sufficiency of which is hereby acknowledged, it is mutually covenanted and
agreed by and among the parties as follows:
<PAGE>

     1.  This Agreement Shall Supercede All Prior Employment Agreements. The
         --------------------------------------------------------------
parties agree that this Agreement shall supercede the November Employment
Agreement and any other prior employment agreements between InfoSpace and Strom,
including all written and oral agreements, except for the Performance Option
Agreement, the Option Agreements and the InfoSpace Employee Non-disclosure
Agreement, the terms of which are incorporated herein subject to any revisions
or modifications made herein. This Agreement shall not affect the Performance
Option Agreement, the Option Agreements, the InfoSpace Employee Nondisclosure
Agreement and the InfoSpace Employee Handbook Acknowledgment between InfoSpace
and Strom except in the manner and to the extent set forth in this Agreement.
The parties agree that (i) the last sentence of the first paragraph of the
InfoSpace Employee Nondisclosure Agreement (the "NDA Agreement") shall be
revised to state that "business" means "the outsourcing or co-branding of fully
integrated private label solutions (as such solutions exist as of December 31,
1999) to web sites or Internet access devices (defined as "InfoSpace
Competitors") (it being agreed that any question as to whether an entity is an
InfoSpace Competitor within such definition shall be determined by the outside
directors of InfoSpace), (ii) the limitation on activities and investment in the
second sentence of the first paragraph of the NDA Agreement shall be superseded
in its entirety by Section 4 of this Agreement, (iii) the provisions of the
third and fourth paragraphs of the NDA Agreement should be revised to limit the
scope of such paragraphs to matters that relate specifically to the "business"
of InfoSpace as defined above, (iv) the provisions of the eighth, twelfth,
thirteenth and fourteenth paragraphs of the NDA Agreement shall be superseded in
its entirety by this Agreement, and (v) the provisions of the tenth paragraph of
the NDA agreement should be revised to omit the words "indirectly" and
"demonstratively anticipated" and (vi) that the InfoSpace Employee Handbook
Acknowledgment shall not be applicable to Strom after January 1, 2000.

     2.  Strom's Position At InfoSpace.  Strom shall continue in her position as
         -----------------------------
President and Chief Operating Officer of InfoSpace through December 31, 1999.

     3.  Strom's Position At InfoSpace's Venture Capital Division. On January 1,
         --------------------------------------------------------
2000, Strom shall assume the position of President of InfoSpace's newly formed
venture capital division (the "Division"). Strom shall remain in the position of
President of the Division until June 30, 2000. Strom shall perform the duties
reasonably necessary to fulfill the responsibilities of such position. All
parties hereto acknowledge and understand that Strom may perform her duties as
President of the Division at a location of her own choice and which may only
require limited attendance at InfoSpace's corporate offices. If, for any reason,
the Division does not exist as of January 1, 2000, then Strom shall assume a
position at InfoSpace to be mutually agreed upon between the parties hereto,
under the same terms and conditions (as set forth herein) that would apply if
she assumed the position of President of the Division. Strom understands that
the Division may be formed as a separate division or a separate entity which may
be a corporation, limited liability corporation or limited partnership. The
Division will be capitalized with at least $15,000,000 and such additional
amount as may be determined by InfoSpace's Board of Directors.

     4.  Outside Activities. During the time in which Strom will perform the
         ------------------
duties of President of the Division, Strom may continue to serve as a director
of other entities and may become a director or chairman of the board of
additional entities, perform part-time consulting services for other entities,
serve as part-time employee of other entities (not to exceed 15 hours of part-
time employment per week in the aggregate) and make investments in other
entities, provided
<PAGE>

that all such activities in the aggregate do not result in Strom being unable to
fulfill her responsibilities as defined in Section 3 and are not with InfoSpace
competitors.

     5.  Salary And Benefits.  Strom's salary and benefits will remain the same
         -------------------
during the remainder of her tenure as President and Chief Operating Officer of
InfoSpace until December 31, 1999.  Strom's salary and benefits as President of
the Division for January 1, 2000 to June 30, 2000 shall be the same as her
salary and benefits as President and Chief Operating Officer of InfoSpace.

     6.  Membership On InfoSpace's Board Of Directors. Strom will remain a
         --------------------------------------------
member of InfoSpace's Board of Directors during the remainder of her tenure as
President and Chief Operating Officer of InfoSpace until December 31, 1999 and
during her employment as President of the Division from January 1, 2000 to June
30, 2000. During this time, Strom may become a member of the Board of Directors
of any other entity, except InfoSpace Competitors. Upon no less than 30 days
notice to InfoSpace, Strom may resign as a director of InfoSpace at any time and
agrees to resign when her employment at InfoSpace terminates.

     7.  No Termination Except For Good Cause. Strom may not be terminated from
         ------------------------------------
her position as President and Chief Operating Officer of InfoSpace, or from her
position as President of the Division prior to June 30, 2000, except for "Good
Cause" which is defined specifically the happening of one or more of the
following events: (a) a repeated, willful failure or a repeated refusal to
comply in any material respect with the reasonable written policies, standards
or regulations of the Company as modified to reflect the performance of services
as contemplated by this Agreement; (b) a repeated willful failure or a repeated
refusal in any material respect, faithfully or diligently, to perform her duties
as described in Section 3 (except due to ill health or disability); (c)
unethical or fraudulent conduct or conduct that materially discredits the
Company or is materially detrimental of the reputation, character or standing of
the Company; (d) dishonest conduct or a deliberate attempt to do an injury to
the Company; (e) a willful and material breach of a term (other than Section 3
which is provided for in (b) above) of this Agreement and the agreements
incorporated herein; (f) a criminal act; or (g) death. Notwithstanding the
foregoing, Strom shall not be deemed to have been terminated for "Good Cause"
without (i) at least 30 days notice to Strom setting forth the reasons and
specific facts for InfoSpace's or the Division's intention to terminate for
"Good Cause," and (ii) an opportunity during such 30 day period for Strom,
together with her counsel, if any, to be heard before the Board of Directors of
InfoSpace and/or for Strom to cure such grounds for termination. After June 30,
2000, Strom's employment shall become at will and may be terminated at any time
by Strom or InfoSpace for any reason or no reason.

     8.  Reimbursement Of Expenses.  During the term of Strom's employment as
         -------------------------
President and Chief Operating Officer of InfoSpace, and as President of the
Division, InfoSpace will continue to reimburse Strom for all expenses reasonably
incurred in the fulfillment of her duties, including, without limitation, travel
expenses, provided such expenses have been preapproved by either Tammy Halstead,
Ellen Alben or John Cunningham.  Strom will submit her actual expenses, on a
monthly basis, to Tammy Halstead, who will make arrangements for reimbursement
of all expenses (within 30 days).

     9.  Voicemail And E-Mail Continued; Computer.  During the term of Strom's
         ----------------------------------------
employment as President and Chief Operating Officer of InfoSpace, and as
President of the Division,
<PAGE>

InfoSpace will continue to provide Strom with all voice-mail and e-mail services
she currently has. Strom may retain her computer after termination of employment
and agrees to promptly delete all InfoSpace proprietary information therefrom.

     10.  Officer And Director Indemnification Continued. During the term of
          ----------------------------------------------
Strom's employment as President and Chief Operating Officer of InfoSpace, and as
President of the Division, InfoSpace will continue to provide Strom with
indemnification and/or insurance, such as Errors and Omissions or Directors and
Officers insurance, in the same manner and to the same extent as is currently in
effect or through purchase of a separate insurance policy.

     11. Stock Option Vesting.  Throughout the remainder of Strom's tenure as
         --------------------
President and Chief Operating Officer of InfoSpace until December 31, 1999, and
during her employment as President of the Division, all stock options to which
Strom is entitled under the Option Agreements shall continue to vest as provided
in those agreements.  During that time, all provisions of all the Option
Agreements shall continue in full force and effect including, without
limitation, all provisions relating to the parties rights in the event of a
change of control of InfoSpace.

     12. Performance Option Agreement.  InfoSpace confirms that Strom has been
         ----------------------------
vested in options to purchase 125,000 shares under the Performance Option
Agreement for 1999.  Strom and InfoSpace agree that the Performance Option
Agreement shall be terminated at the effective date of this Agreement and Strom
shall not be entitled to any further awards of options under such agreement.

     13. Term Loan For Stock Option Exercise And Taxes. Commencing as of the
         ---------------------------------------------
date of this Agreement, InfoSpace will extend a term loan in an amount not to
exceed $10,000,000 to Strom for the purpose of (i) exercising stock options to
which Strom becomes or has become entitled under the Option Agreements; and (ii)
paying the Federal taxes due upon exercise of those stock options (the "Term
Loan"). The Term Loan will be subject to a interest rate equal to the prime rate
as adjusted from time to time, compounded annually. The Term Loan and interest
accrued thereon will be secured by an escrow account, but with full recourse
against Strom. Each time Strom utilizes the Term Loan in order to exercise
options, Strom will place into escrow a sufficient number of shares of InfoSpace
stock (which, for this purpose, shall be valued at the fair market value at the
time of exercise) equal to two times the amount advanced to secure the amount
advanced for the purchase of the shares, in addition to the amount advanced for
payment of taxes incurred as a result of the exercise. For purposes of
calculations under this provisions, Strom shall be deemed to have total tax
liability in the 40% tax bracket. The Term Loan shall remain open for a period
of 2 years from the date of this Agreement, at which time the entire amount of
the Term Loan which remains unpaid, in addition to the interest accrued thereon,
shall become due and payable.

     14.  Relocation Expenses. From the date of this Agreement to June 30, 2001,
          -------------------
Strom may, at her sole discretion, give notice to InfoSpace of her decision to
relocate and to sell the Kirkland Residence. InfoSpace agrees that if during
such period prior to June 30, 2001, Strom intends to enter into an agreement (as
evidenced by a bona fide written offer to purchase) to sell such Kirkland
Residence for a price after deduction of customary closing costs to be paid by
Strom (the "Net Purchase Price") less than $3,600,000 (the price Strom paid for
such residence, not including any improvements by Strom), then InfoSpace will
either, at its option, pay to Strom the difference
<PAGE>

between $3,600,000 and the Net Purchase Price or purchase the Kirkland Residence
from Strom at the Net Purchase Price. The provisions of Section 14 shall not be
applicable if Strom is terminated for "Good Cause."

     15. Severance Package.  The day following Strom's last day of employment as
         -----------------
President of the Division unless such employment is earlier terminated for "Good
Cause", InfoSpace shall pay Strom a severance amount equal to $250,000 and
InfoSpace shall maintain Strom's life insurance, health insurance and dental
insurance, at the present rate until the earlier of one year from her last day
of employment, or the date Strom accepts employment with another entity
providing such benefits.  The benefits in this Section 15 shall be payable to
Strom if she is terminated voluntarily or without "Good Cause."  It shall be a
condition of the receipt of such amounts in this Section 15 and the amount
provided in Section 14 that Strom enter into a mutual release as of the date of
the payment of such $250,000 in the form of Section 20.

     16.  Public Announcement And Non-Disparagement.  After execution of this
          -----------------------------------------
Agreement, the parties hereto will agree on the wording of a public
announcement, an internal announcement and a response to any request for
references describing the relationship between Strom, InfoSpace and the
Division.  The parties agree that neither InfoSpace, the Division nor Strom, nor
any member of the Board of Directors, officer, employee or agent of InfoSpace or
the Division, shall make any statement to the press or any individual or entity
that relates to InfoSpace's business or related activities or the relationship
between the parties that in anyway disparages the other party or InfoSpace's
officers or directors.  This Agreement regarding non-disparagement shall be
personally binding upon all members of the Board of Directors of InfoSpace and
all officers of InfoSpace.  Neither party will disclose the terms of this
Agreement, unless and until this Agreement is filed as required as an exhibit to
InfoSpace's Form 10-K or other SEC filing.

     17. Arbitration.
         -----------

         (a)  Agreement. In consideration of this Agreement, InfoSpace and Strom
agree that any dispute and/or claim between InfoSpace and Strom that (i)
underlies, (ii) relates to, (iii) and/or is asserted following the termination
of, her employment relationship with InfoSpace and that cannot be otherwise
resolved will be submitted to final, binding arbitration in accordance with the
National Rules for the Resolution of Employment Disputes of the American
Arbitration Association that are then in effect. (Copies of the current rules
are available from InfoSpace's human resources department.) This Agreement also
governs any claims that Strom may have against InfoSpace's officers, directors,
employees, agents and shareholders. Strom and InfoSpace understand that,
pursuant to this Agreement, each foregoes and waives the right to take any
covered dispute or claim to civil litigation in court. Strom and InfoSpace
understand that this Agreement governs any claim each may have that underlies,
relates to and/or is asserted following the termination of her employment
relationship with InfoSpace, including, but not limited to, claims of wrongful
discharge, infliction of emotional distress, breach of contract, breach of any
covenant of good faith and fair dealing, and claims of retaliation and/or
discrimination in violation of any local, state or federal law. Examples of such
laws include Title VII of the Civil Rights Act of 1964, as amended; the Age
Discrimination in Employment Act; the Americans with Disabilities Act; the
Family and Medical Leave Act, and state and local laws applicable to her
employment. This Agreement does not affect Strom's right to pursue worker's
compensation or unemployment compensation benefits for which
<PAGE>

she may be eligible in accordance with state law, nor does it affect her right
to file and/or to cooperate in the investigation of an administrative charge of
discrimination.

     Strom and InfoSpace understand that each may seek in arbitration any remedy
or award that would be available to each through civil litigation and the
arbitrator has authority to grant any such remedy or award.  Strom and InfoSpace
agree that such remedies include monetary damages but do not include
reinstatement unless authorized by statute.

     In any matter that is presented to an arbitrator under this Agreement,
Strom and InfoSpace agree that the location of the arbitration hearing(s) will
be in Redmond, Washington, unless another location is mutually agreed upon.

     Strom and InfoSpace enter into this Agreement freely and voluntarily in
consideration for her employment with InfoSpace, the compensation and benefits
she receives based on that employment and InfoSpace's mutual agreement for
arbitration.

         (b)  Governing Law. The arbitrator shall apply the law of the State of
              -------------
Washington to the merits of any dispute or claim, without reference to rules of
conflict of law. Each party hereby expressly consents to the personal
jurisdiction of the state and federal courts located in the State of Washington
for any action or proceeding arising from or relating to this Agreement or
relating to any arbitration in which the parties are participants.

         (c)  Costs and Fees of Arbitration. The prevailing party in any
              -----------------------------
arbitration or legal proceeding hereunder shall be entitled to recover her or
its attorneys' fees and expenses from the losing party.

         (d)  Equitable Relief. The parties may apply to any court of competent
              ----------------
jurisdiction for a temporary restraining order, preliminary injunction, or other
interim or conservatory relief, as necessary, without breach of this arbitration
agreement and without abridgment of the powers of the arbitrator.

     18. Successors.
         -----------

         (a)  InfoSpace's Successors. Any successor to InfoSpace (whether direct
              ----------------------
or indirect and whether by purchase, lease, merger, consolidation, or otherwise)
to all or substantially all of InfoSpace's business and/or assets shall assume
the obligations under this Agreement and agree expressly to perform the
obligations under this Agreement in the same manner and to the same extent as
InfoSpace would be required to perform such obligations in the absence of a
succession. For all purposes under this Agreement, the term "InfoSpace" shall
include any successor to InfoSpace's business and/or assets which executes and
delivers the assumption agreement described in this subsection (a) or which
becomes bound by the terms of this Agreement by operation of law.

         (b)  Strom's Successors. Without the written consent of InfoSpace,
              ------------------
Strom shall not assign or transfer this Agreement or any right or obligation
under this Agreement to any other person or entity. Notwithstanding the
foregoing, the terms of this Agreement and all rights of Strom
<PAGE>

hereunder shall inure to the benefit of, and be enforceable by, Strom's personal
or legal representatives, executors, administrators, successors, heirs,
distributees, devisees and legatees.

     19.  Notice Clause.
          -------------

          (a)  Manner. Any notice hereby required or permitted to be given shall
               ------
be sufficiently given if in writing and upon mailing by registered or certified
mail, postage prepaid, to either party at the address of such party or such
other address as shall have been designated by written notice by such party to
the other party.

          (b)  Effectiveness. Any notice or other communication required or
               -------------
permitted to be given under this Agreement will be deemed given on the day when
delivered in person, or the third business day after the day on which such
notice was mailed in accordance with Section 18(a).

     20.  Mutual Release of Claims.
          ------------------------

          (a) General Release.  Strom expressly waives any claims against
              ---------------
InfoSpace and releases InfoSpace (including its owners, officers, directors,
stockholders, managers, agents, employees and representatives) (collectively
"InfoSpace") from any and all actual or potential actions, claims or causes of
action and damages known or unknown from any and all actual or potential
actions, claims, causes of action, and damages, known or unknown and InfoSpace
expressly waives any claims against Strom and releases Strom from any and all
actual or potential actions, claims or causes of action and damages known or
unknown from any and all actual or potential actions, claims, causes of action,
and damages, known or unknown, in all cases on account of or arising out of
Strom's employment relationship with InfoSpace or the change in or the
termination thereof in accordance with this Agreement.  It is understood that
other than as provided pursuant to this Agreement, this release includes, but is
not limited to, any claims for wages, bonuses, or other compensation, including
but not limited to stock or stock options, employment benefits, or damages of
any kind whatsoever, arising out of any common law torts, arising out of any
contracts, express or implied, any covenant of good faith and fair dealing,
express or implied, any theory of wrongful discharge, any theory of negligence,
any theory of retaliation, any theory of discrimination or harassment in any
form, any legal restriction on InfoSpace's right to terminate employees, or any
federal, state, or other governmental statute or ordinance, including, without
limitation, Title VII of the Civil Rights Act of 1964 as amended, the Americans
with Disabilities Act, the Age Discrimination in Employment Act, the Older
Workers Benefit Protection Act, the Washington Law Against Discrimination, or
any other legal limitation on or regulation of the employment relationship.
Strom agrees to indemnify and hold InfoSpace harmless from and against any and
all loss, costs, damages, or expenses, including, without limitation, reasonable
attorneys' fees incurred by InfoSpace or arising out of any breach of this
Agreement by Strom or resulting from any representation made herein by Strom
that was false when made.  InfoSpace agrees to indemnify and hold Strom harmless
from and against any and all loss, costs, damages, or expenses, including,
without limitation, reasonable attorneys' fees incurred by Strom or arising out
of any breach of this Agreement by InfoSpace or resulting from any
representation made herein by InfoSpace that was false when made.  This waiver
and release shall not preclude either party from proceeding with arbitration as
provided herein for the exclusive purpose of enforcing its rights under this
Agreement.
<PAGE>

         (b) No Admission of Wrongdoing. This Agreement shall not be construed
             --------------------------

discrimination, or breach of contract, and InfoSpace and Strom specifically

Strom with any governmental agency or any court, and agrees that each will not
initiate, assist, participate in, or encourage in any such actions, except as

agency or court assumes jurisdiction of any complaint or charge against
InfoSpace on behalf of Strom or against Strom on behalf of InfoSpace that the
other party will request the agency or court to withdraw from the matter and
dismiss it with prejudice.

     21.   Governing Law.  This Agreement shall be governed by and construed
           -------------
in accordance with the internal substantive laws, but not the choice of law
rules, of the State of Washington.

     22.   Severability. The invalidity or unenforceability of any provision
           ------------
of this Agreement, or any terms hereof, shall not affect the validity or
enforceability of any other provision or term of this Agreement.

     23.   Integration.  This Agreement represents the entire agreement and
           -----------
understanding between the parties as to the subject matter herein and supersedes
all prior or contemporaneous agreements whether written or oral.  No waiver,

                                   AGREEMENT

     This Agreement is entered into as of February 10, 2000 by and between
InfoSpace.com, Inc., a Delaware corporation, Naveen Jain, and each of the
undersigned individuals.

     WHEREAS, at the time of the Company's initial public offering in December
1998, the parties to this Agreement entered into a Indemnification Agreement
dated as of December 11, 1998, whereby Mr. Jain, as the Company's majority
stockholder, agreed to provide 1,000,000 shares (before adjustment for stock
splits after such date) of his Common Stock into an escrow fund to provide
indemnification to the Company and the Company's directors in connection with
certain potential claims against the Company arising from activities of the
Company prior to the initial public offering, and

     WHEREAS, the purpose of that Agreement was to enable the Company to
complete its initial public offering and assure that, should any of such claims
related to the Company's business prior to the public offering arise, the
Company would have an escrow fund available which would provide further
assurances to the underwriters and the public investors in connection with the
Company's initial public offering, and

     WHEREAS, the Company completed its initial public offering and, under the
leadership of Mr. Jain, has substantially increased its business and its market
capitalization, and

     WHEREAS, the Company, Mr. Jain and the undersigned individuals wish to
enter into this Agreement terminating the Indemnification Agreement and
providing that Mr. Jain will enter into a two (2) year non-competition agreement
with the Company.

written consent of InfoSpace.com. Also, during my employment, I will not engage
in any activity or investment (other than an investment of less than .01% of the
shares of a company traded on registered stock exchange), that (a) conflicts

InfoSpace.com's Special Projects Committee.  As used herein, InfoSpace.com's
------------------------------------------

Internet.

2.   At all times during my employment and thereafter I will not disclose to
anyone outside InfoSpace.com nor use for any purpose other than my work for

any information InfoSpace.com has received from others which InfoSpace.com is
obligated to treat as confidential or proprietary or (c) any confidential or
proprietary information which is circulated within InfoSpace.com via its
internal email system or otherwise.  I will also not disclose any confidential
information inside InfoSpace.com except on "need to know" basis.  If I have any
questions as to what comprises such confidential proprietary information or
trade secrets, or to whom, if anyone, inside InfoSpace.com, it may be disclosed,
I will consult my manager at InfoSpace.com

3.   I will make prompt and full disclosure to InfoSpace.com, will hold in trust
for the sole benefit of InfoSpace.com, and will assign exclusively to

material, and trade secrets (collectively herein "inventions") that I, solely or
jointly, may conceive, develop, or reduce to practice during the period of time

InfoSpace.com any and all claims of any nature whatsoever that I now or
