OFFER TO EXCHANGE CERTAIN OUTSTANDING OPTIONS TO PURCHASE COMMON STOCK
FOR SHARES OF RESTRICTED STOCK
(THE "OFFER TO EXCHANGE")

-----------------

October 29, 2001

INFOSPACE, INC.

Offer to Exchange Certain Outstanding Options to Purchase Common Stock for
Shares of Restricted Stock (the "Offer to Exchange")

The offer and withdrawal rights expire at 9:00 p.m., Pacific Standard Time, on
November 26, 2001, unless the offer is extended.

InfoSpace, Inc., a Delaware corporation ("InfoSpace"), is offering eligible
employees the opportunity to exchange certain outstanding options to purchase
shares of our common stock for shares of our common stock that will vest after
the date of issuance in equal amounts every three months beginning February 27,
2002 (the "restricted stock"). We will grant the restricted stock under the
InfoSpace, Inc. 2001 Nonstatutory Stock Option Plan (the "2001 Plan"). We are
making the offer upon the terms and conditions described in (i) this "Offer to
Exchange;" (ii) the related letter from Naveen Jain, Chairman and Chief
Executive Officer of InfoSpace, dated October 29, 2001; (iii) the Election
Form; and (iv) the Notice to Withdraw from the Offer (which together, as they
may be amended from time to time, constitute the "offer").

All tendered options accepted by us through the offer will be cancelled
promptly following the date the offer ends. The offer is presently scheduled to
expire on November 26, 2001 (the "Expiration Date"), and we expect to cancel
options on November 28, 2001, or as soon as possible thereafter (the
"Cancellation Date").

We will not be obligated to accept any options and grant and restricted
stock pursuant to this offer if optionholders as a group tender options to
purchase less than 46,755,234 shares of our common stock (95% of the aggregate
shares underlying the Eligible Options and Special Options). However, we may
choose to cancel options and grant restricted stock pursuant to this offer if
options to purchase less than 46,755,234 shares of our common stock are
tendered. This offer is also subject to other conditions. Participation in the
offer is completely voluntary. The offer is subject to conditions that we
describe in Section 7 of this Offer to Exchange.

You may participate in the offer if you are a full-time U.S.-based employee
of InfoSpace or its subsidiary Saraide Inc. hired on or before October 26,
2001, as of the date the offer commences and through the Cancellation Date.
Employees of InfoSpace or one of its United States subsidiaries that are not
paid through a U.S. payroll will not be entitled to participate in the offer.
In order to actually receive the restricted stock pursuant to this offer, you
must continue to be a full-time U.S.-based employee as of the date on which the
restricted stock is granted. You may only tender outstanding vested and
unvested options from the Restated 1996 Flexible Stock Incentive Plan (the
"1996 Plan") or the 2001 Plan granted on or after February 6, 2001 which have
an exercise price of $3.00 or more per share of the common stock underlying
such options (the "Eligible Options"). You may only tender all or none of your
Eligible Options with an exercise price of $3.00 or more. We will not accept
partial tenders of options. Participating employees also will be required to
surrender, in addition to the Eligible Options, all of their outstanding
unexercised options having an exercise price of $3.00 or more per share
(including options to purchase Saraide common stock) granted under the 1996
Plan, the 2001 Plan, the Go2Net Inc. 1996 Stock Option Plan, the Go2Net Inc.
2000 Stock Option Plan, the Silicon Investor, Inc. 1996 Stock Plan, the WEB 21
Stock Option Plan, the Authorize.Net Corporation 1999 Stock Incentive Plan, the
IQC Corporation Option to Purchase Common Stock, the SaveSmart, Inc. 1997
Equity Incentive Plan, the Saraide.com Inc. 1998 Equity Incentive Plan, the
InfoSpace, Inc. and Saraide Inc. 2000 Stock Plan and the INEX Corporation Share
Option Plan regardless of when granted or whether vested or unvested (the
"Special Options"). No restricted stock will be granted in exchange for the
Special Options. In exchange for the Eligible Options you tender that are
accepted for exchange and cancelled by us, you will receive one share of
restricted stock for every four (4) shares of common stock underlying the
Eligible Options you tender.

If you tender options for exchange as described in this offer, we will issue
you restricted stock under the 2001 Plan. The restricted stock will be
available for issuance on the date the tendered options are accepted and
cancelled. Regardless of the vesting schedules of the options that you tender
to us, the restricted stock issued to you will vest after the date of issuance
in equal amounts every three months beginning February 27, 2002, assuming that
you meet the requirements for vesting specified in the restricted stock
agreement between you and us. Until it vests, the restricted stock will be held
in the custody of Paine Webber and will be subject to certain forfeiture
provisions and transfer restrictions set forth in the restricted stock
agreement. UNDER U.S. TAX LAWS, IF YOU DO NOT MAKE AN ELECTION UNDER SECTION
83(b) OF THE INTERNAL REVENUE CODE, THE VESTING OF YOUR RESTRICTED STOCK WILL
RESULT IN YOUR RECOGNITION OF TAXABLE INCOME ON EACH VESTING DATE. IF YOU DO
MAKE AN ELECTION UNDER SECTION 83(b) OF THE INTERNAL REVENUE CODE, YOU WILL
RECOGNIZE TAXABLE INCOME FOR ALL OF THE SHARES ON THE DATE OF GRANT.

As of October 25, 2001, the total number of option shares eligible for the
offer is 29,661,690. Assuming that all of the Eligible Option shares are
tendered for the exchange, we would issue up to 7,416,038 shares of restricted
stock in exchange for shares underlying the Eligible Options, which is
approximately 3% of our total shares outstanding following the issuance.

ALTHOUGH OUR BOARD OF DIRECTORS HAS AUTHORIZED THE OFFER, NEITHER WE NOR OUR
BOARD OF DIRECTORS MAKE ANY RECOMMENDATION AS TO WHETHER YOU SHOULD TENDER OR
NOT TENDER YOUR OPTIONS FOR EXCHANGE. YOU MUST MAKE YOUR OWN DECISION WHETHER
OR NOT TO TENDER YOUR OPTIONS.

Shares of InfoSpace common stock are traded on the Nasdaq National Market
under the symbol "INSP." On October 26, 2001, the closing price of our common
stock reported on the Nasdaq Stock Market was $1.67 per share.

WE RECOMMEND THAT YOU EVALUATE CURRENT MARKET QUOTES FOR OUR COMMON STOCK,
AMONG OTHER FACTORS, BEFORE DECIDING WHETHER OR NOT TO TENDER YOUR OPTIONS.

SUMMARY TERM SHEET

The following are answers to some questions that you may have about this
offer. We urge you to read carefully the remainder of this Offer to Exchange
and the accompanying materials because the information in this summary and in
the introduction preceding the summary are not complete and may not contain all
of the information that is important to you. We have included references to the
relevant sections of this Offer to Exchange where you can find more complete
descriptions of the topics in this summary.

1. Why are we making the offer?

Our board of directors has authorized this exchange in order to provide
eligible employees an incentive for their continued efforts and dedication. As
a company, we are committed to employee ownership because it helps us attract
and retain the best and brightest employees. (Page 18)

2. Who is eligible to participate in the offer?

You are an employee eligible to participate in the offer (an "Eligible
Employee") if (1) you are a full-time U.S. based employee of InfoSpace, Inc. or
Saraide Inc. working in the U.S. and are paid through U.S. payroll, (2) you
were hired on or before October 26, 2001, (3) you are employed by InfoSpace or
one of its U.S. subsidiaries on the date this offer is made and remain employed
as of the date the tendered options are accepted for exchange and the date the
restricted stock is granted, and (4) you hold one or more options to purchase
InfoSpace common stock granted on or after February 6, 2001 under the 2001
Nonstatutory Stock Option Plan (the "2001 Plan") or the Restated 1996 Flexible
Stock Incentive Plan (the "1996 Plan").

You are not eligible to participate in the offer if (1) you are a non-U.S.
based employee of InfoSpace or one of its subsidiaries, (2) you were hired
after October 26, 2001, (3) you are employed by InfoSpace or a U.S. subsidiary
of InfoSpace, but you are paid through payroll outside the U.S. or only work
part-time, (4) you are a non-employee member of our board of directors, (5) you
are a consultant or contractor, or (6) you are not an Eligible Employee as
described above. (Page 16)

3. If I meet the eligibility requirements, but I'm on an approved leave of
absence during the election period, can I still participate?

Yes. If you meet the eligibility requirements, but you are on an approved
leave of absence during the election period, we will provide you documents
relating to the offer, including, among other things, an Election Form.
However, if you are absent for more than 50% of any given vesting period due to
being on an approved leave of absence you would not receive any vesting for
that period, and the vesting of your restricted stock will be suspended for
that period. For any such vesting period in which an employee does not vest due
to having been on an approved leave of absence for more than 50% of that
vesting period, an additional vesting period will be added on to the end of the
vesting schedule for that employee subject to the terms and conditions of the
rest of this Offer to Exchange. (Page 16)

4. What securities are we offering to exchange?

We are offering to exchange all stock options having an exercise price of
$3.00 or more that were granted under our 2001 Plan and our 1996 Plan on or
after February 6, 2001 ("Eligible Options") to Eligible Employees. In return
for your tender of Eligible Options, you will receive a certain number of
shares of restricted stock. Although we will not issue restricted stock in
exchange for any Special Options (described below) you hold, if you elect to
accept this offer, you must return also all your Special Options for
cancellation. If you elect to participate in the exchange, you will also be
eligible to receive a Supplemental Grant (described below). (Page 16)

5. What are the Special Options?

The Special Options are all outstanding options you hold, other than
Eligible Options, with exercise prices equal to or greater than $3.00 per share
granted under: the 1996 Plan, the 2001 Plan, the Go2Net Inc. 1996 Stock Option
Plan, the Go2Net Inc. 2000 Stock Option Plan, the Silicon Investor, Inc. 1996
Stock Plan, the WEB 21 Stock Option Plan, the Authorize.Net Corporation 1999
Stock Incentive Plan, the IQC Corporation Option to Purchase Common Stock, the
SaveSmart, Inc. 1997 Equity Incentive Plan, the Saraide.com Inc. 1998 Equity
Incentive Plan, the InfoSpace, Inc. and Saraide Inc. 2000 Stock Plan and the
INEX Corporation Share Option Plan, regardless of when granted or whether
vested or unvested. If you elect to participate in the offer, you will be
required to tender all Special Options you hold. However, no restricted stock
will be issued in exchange for the Special Options. (Page 17)

6. What is restricted stock?

When you receive "restricted stock" you become a holder of shares of
InfoSpace common stock. These shares are "restricted" because they are subject
to forfeiture and restrictions on transfer until the restrictions lapse, at
which time the shares "vest." The forfeiture and transfer restrictions will be
set forth in a restricted stock agreement entered into by you and us. Once
shares of restricted stock have vested, those shares will be yours to hold,
transfer or sell as you desire, subject to applicable securities laws and
payment of withholding taxes. In contrast, a stock option, when vested, gives
the option holder a contractual right (subject to the terms and conditions of
the option plan and option agreement) to purchase shares of common stock at a
certain price for a specified period. (Page 24)

7. How many shares of restricted stock will I receive in exchange for the
options I return?

You will receive one (1) share of restricted stock for every four (4) shares
covered by an Eligible Option that you tender. All fractional amounts will be
rounded up. For example, assume that you tender an Eligible Option covering
3,750 shares. 3,750 shares divided by 4 equals 937.5. The restricted stock
grant would be rounded up to 938 shares. (Page 17)

You will not receive any restricted stock in exchange for the Special
Options. However, if you elect to participate in the exchange, you may be
eligible to receive a supplemental restricted stock grant ("Supplemental
Grant") granted by the board of directors of InfoSpace, in its sole discretion.
The board of directors has reserved approximately 8,000,000 shares of
restricted stock to make the Supplemental Grants. The number of shares of
restricted stock granted as Supplemental Grants, if any, will vary among
employees. The terms of the Supplemental Grants will be the same as the terms
of the restricted stock granted in exchange for the Eligible Options. Eligible
Employees must participate in the exchange offer in order to be eligible to
receive a Supplemental Grant. (Page 17)

8. If I elect to exchange eligible options, do I have to exchange all of my
options or can I just exchange some of them?

If you elect to participate in the exchange, you must tender all of your
Eligible Options and Special Options. Partial tenders of Eligible Options and
Special Options are not permitted. (Pages 17 and 21)

9. When will I receive my restricted stock?

The restricted stock will be granted on November 28, 2001, unless we extend
this Offer to Exchange or unless we decide to reject all tendered options. We
expect to distribute the restricted stock agreements promptly after expiration
of this Offer to Exchange and after we have accepted and cancelled the tendered
options. Your award of restricted stock will be evidenced by a restricted stock
agreement between you and us, but you will not receive a stock certificate for
the restricted stock. Until the restricted stock vests, it will be held in the
custody of Paine Webber. Generally, as the shares vest, they will be deposited
into your account with Paine Webber, subject to payment of applicable
withholding taxes. (Page 21)

10. What is the vesting schedule for the restricted stock?

The shares of restricted stock will vest over a two-year period that will
begin on the exchange date (assuming your continued employment). Subject to the
terms and conditions of the 2001 Plan and the restricted stock agreement, 12.5%
of the shares will vest every three-month period beginning on February 27, 2002
(February 27, 2002, May 27, 2002, August 27, 2002, November 27, 2002, February
27, 2003, May 27, 2003, August 27, 2003 and November 27, 2003). Vesting will
only occur, however, if you are employed by InfoSpace or one of its
subsidiaries through the respective vesting dates. Even if the options you
exchange are partially or fully vested, the shares of restricted stock you
receive will not be vested and will be subject to the new vesting period. (Page
24)

If you are absent for more than 50% of any given vesting period due to being
on an approved leave of absence, the vesting of your restricted stock will be
suspended for that period. The vesting that you missed generally will be added
on at the end of the regularly scheduled vesting period. For example, assume an
employee goes out on an approved leave of absence on February 1, 2002 and
returns on May 1, 2002. The employee would vest for the period ending on
February 27, 2002 because he or she worked for more than 50% of that vesting
period. He or she would not vest for the period ending on May 27, 2002 because
he or she would have been on leave for more than 50% of that vesting period. An
additional vesting period would be added on at the end and the employee would
be scheduled to be 100% vested on February 27, 2004. (Page 25)

If you change your status from full-time to part-time and your status is
part-time for more than 50% of any given vesting period, vesting of your
restricted stock will be suspended until the next period in which you are
full-time for more than 50% of the given vesting period. The vesting period(s)
that you missed will be added on at the end of the vesting schedule.

In addition, certain members of senior management will be entitled to
accelerated vesting of any unvested restricted stock if their employment is
terminated as a result of an involuntary termination within 24 months following
a change of control of InfoSpace. (Page 25)

11. Under what circumstances will I forfeit the restricted stock I receive in
the exchange?

Prior to vesting, your unvested restricted stock will be forfeited
completely if you leave InfoSpace for any or no reason, including voluntary
resignation or termination of your employment by us with or without cause.
Whatever shares vest while you remain an InfoSpace employee are yours to keep
even after you leave InfoSpace. However, as described in Question 10 above,
certain members of senior management whose employment terminates within 24
months of a change of control may be entitled to receive accelerated vesting.
Your restricted stock agreement will contain the particular provisions
regarding the effect of an acquisition on your restricted stock. (Page 25)

12. What are the other restrictions on the restricted stock?

The restrictions on the restricted stock you receive in this exchange will
be set forth in your restricted stock agreement. Restricted stock generally may
not be sold, transferred, assigned, pledged or otherwise encumbered or disposed
of until the stock vests. Until then, the restricted stock will be held in the
custody of Paine Webber. Once the restricted stock has vested, the stock will
no longer be subject to forfeiture in connection with your employment with
InfoSpace. (Page 24)

13. Will I receive a stock certificate representing the restricted stock?

Your award of restricted stock will be evidenced by the restricted stock
agreement between you and us, and you will not receive a stock certificate for
the restricted stock. Until the restricted stock vests, it will be held in the
custody of Paine Webber. Following each vesting date, if you are still employed
by us, have signed the restricted stock agreement and related documents and
have opened your account with Paine Webber, and subject to the terms and
conditions of the 2001 Plan and the restricted stock agreement, 12.5% of the
shares of your original award of restricted stock will be deposited into your
Paine Webber account within approximately six business days, subject to payment
of applicable withholding taxes. (Page 24)

14. Am I entitled to exercise any rights of ownership of restricted stock while
the stock is subject to restriction?

Once the restricted stock is granted, you will be treated as a stockholder.
This will entitle you to voting, dividend and other stockholder rights (subject
to the transfer and forfeiture restrictions of your restricted stock) with
respect to all shares of restricted stock, whether vested or unvested.
InfoSpace will deliver to you, by mail or otherwise, all notices of meetings,
proxies and other materials distributed to all of our stockholders. (Page 24)

15. Are there conditions to the offer to exchange?

We are not obligated to accept the tendered options if optionholders as a
group tender options to purchase less than 46,755,234 of shares of our common
stock (95% of the aggregate shares underlying the Eligible Options and Special
Options). However, we may choose to cancel options and grant restricted stock
pursuant to this offer if options to purchase less than 46,755,234 shares of
our common stock are tendered. This offer is also subject to other conditions
described in Section 7. (Page 22)

16. If I am eligible to participate in the exchange, will I be eligible to
receive other option grants?

InfoSpace will not issue any new options to an Eligible Employee for a
period of at least six months from the date of the restricted stock grant,
regardless of whether or not the Eligible Employee participates in the offer.
We will defer the grant of new options to Eligible Employees because it is
necessary for us to do so to avoid incurring compensation expense because of
accounting rules that could apply to such interim option grants as a result of
the offer. Therefore, Eligible Employees, regardless of whether they
participate in the exchange, generally will not be eligible to receive any new
option grants until the 2002 annual review currently scheduled for October
2002. (Page 21)

17. What happens if I choose not to participate in the exchange?

If you choose not to accept the offer to exchange, the options you currently
hold will remain outstanding without modification and you will remain eligible
to receive future option grants. However, assuming we complete the exchange, we
will not issue any new options to you or any other Eligible Employee for a
period of at least six months from the date the restricted stock is issued
regardless of whether you participate in the exchange. (Page 19)

If you choose not to accept the offer, you will not receive a supplemental
grant for which you might otherwise have been eligible.

If Eligible Employees tender options representing less than 46,755,234
shares (95% of shares underlying Eligible Options and Special Options), we may
elect not to complete the exchange. If we do not complete the exchange, our
board of directors has not approved any plans to make additional stock option
grants prior to the 2002 annual review, currently scheduled for October 2002,
or otherwise issue the supplemental grants of restricted stock described in
these offering materials. (Page 22)

If any of your Eligible Options or Special Options qualify as "incentive
stock options" for tax purposes and you choose not to tender them, the tax
treatment of those options may be adversely impacted. (See Q&A number 20 and
page 32)

18. What is the source of the common stock that will be used to exchange for my
options?

The restricted stock offered to option holders will be issued under the 2001
Plan and will be drawn from the pool of common stock currently authorized for
issuance under that Plan. All options under the 1996 Plan and the 2001 Plan
returned to us in the tender offer will be cancelled and those shares will be
returned to the Plans from

which they were granted, thereby permitting the issuance of the restricted
stock under the 2001 Plan and providing additional stock for future awards
under the 1996 Plan and 2001 Plan. (Page 23)

19. What are the U.S. tax effects for the restricted stock?

Assuming you do not make an election under Section 83(b) of the Internal
Revenue Code, you will have no taxable income at the time we grant you the
restricted stock in exchange for your tendered Eligible Options. Instead, you
will recognize ordinary income when (and if) the restricted stock vests. If you
make a Section 83(b) election, you recognize ordinary income at the time of
grant of the restricted stock. However, if you later forfeit the restricted
stock, no tax deduction is allowed with respect to the forfeiture. That is, you
will not receive any credit for taxes paid with respect to such forfeited
stock. In all cases, the amount of ordinary income that you recognize will
equal the fair market value of the shares at the time you recognize income.

For example, if you receive 3,200 shares of restricted stock on November 28,
2001, 400 shares would vest every three months, beginning February 27, 2002.

If you do not make an election under Section 83(b) of the Code, on or before
December 27, 2001, you would recognize ordinary income for 400 shares on
February 27, 2002 and the amount would be the closing price of our common stock
on the following market trading day. If our stock price is $1.00 on February
28, 2002, you would recognize $400 of ordinary income. If on February 28, 2002,
our stock price is $1.25, you would recognize $500 of ordinary income.

If you do make an election under Section 83(b) of the Code, you would
recognize ordinary income for all 3,200 shares on November 28, 2001, the date
of grant. If our stock price is $1.00 on November 28, 2001, you would
immediately recognize $3,200 of ordinary income. The subsequent vesting of the
shares does not trigger additional recognition of ordinary income.

Upon the subsequent sale of the shares, any gain or loss will be treated as
capital gain or loss. Capital gains are grouped and netted by holding periods.
Net capital gain on assets held twelve (12) months or less is taxed at your
highest marginal income tax rate. Net capital gain on assets held for more than
twelve (12) months is taxed currently at a maximum federal rate of 20%. Capital
losses are first allowed in full against capital gains and then up to $3,000
against other income. (Page 31)

PLEASE BE AWARE THAT THE STOCK PRICES LISTED ABOVE ARE ONLY BEING USED AS
EXAMPLES. WE ARE NOT MAKING ANY REPRESENTATIONS, WARRANTIES OR COVENANTS THAT
INFOSPACE'S STOCK PRICE WILL ACTUALLY ACHIEVE THE AMOUNTS INDICATED AS OF SUCH
DATES OR ON ANY DATE.

THE PREVIOUS DISCUSSION REGARDING TAXES IS INTENDED ONLY AS A SUMMARY OF THE
GENERAL U.S. TAX LAWS THAT MAY APPLY TO THE RESTRICTED STOCK. THE FEDERAL,
STATE AND LOCAL TAX CONSEQUENCES TO ANY PARTICULAR INDIVIDUAL WILL DEPEND UPON
HIS OR HER INDIVIDUAL CIRCUMSTANCES. ACCORDINGLY, WE STRONGLY ADVISE YOU TO
SEEK THE ADVICE OF A QUALIFIED TAX ADVISOR REGARDING YOUR PARTICIPATION IN THE
OFFER.

20. If I have incentive stock options, what happens if I elect not to exchange
them in this offer?

We do not believe that our offer to you will change any of the terms of your
incentive stock options if you do not accept the offer. However, the IRS may
characterize our offer to you as a "modification" of options eligible for
tender that qualify for favorable tax treatment as incentive stock options (but
not non-qualified stock options), even if you decline the offer. A successful
assertion by the IRS that the options are modified could extend the period of
time that you are required to hold the options to qualify for favorable tax
treatment and cause a portion of your incentive stock options to be treated as
nonqualified stock options. (Page 32)

21. How will withholding taxes be handled when my restricted stock vests?

At the time you recognize ordinary income (either upon vesting or, if you
make an election under Section 83(b) of the Code, upon grant), we will have a
withholding tax obligation, much like the obligation that arises when we pay
your salary. This ordinary income will be reflected on your year-end W-2. In
order to facilitate the payment of this withholding tax obligation, we have
arranged with Paine Webber to sell a portion of your shares of restricted stock
(including any Supplemental Grants) as they vest that is sufficient to pay the
withholding obligation, and this arrangement will be reflected in your
restricted stock agreement and your Irrevocable Standing Order to Sell Shares.
Specifically, the following will happen:

. You will be required to open an account with Paine Webber prior to the
vesting of your shares of restricted stock. We will require you to sign
and return the Irrevocable Standing Order to Sell Shares prior to any
vesting of your shares. The Irrevocable Standing Order to Sell Shares
includes provisions authorizing Paine Webber to sell a portion of your
shares of restricted stock to pay withholding taxes.

Note: If you are an executive of InfoSpace subject to the reporting
requirements of Section 16 of the Securities Act of 1934, as amended, or
you are a specifically named "Covered Person'' under the InfoSpace Company
Policy Regarding Special Trading Procedures, you may be required to file
with the SEC a 10b5-1 trading plan in lieu of signing and delivering an
Irrevocable Standing Order to Sell Shares.

. If you make a Section83(b) election, you must pay over to us the amount of
the withholding taxes by check at the time of the election. If you do not
pay over the amount of withholding taxes by check, your Section 83(b)
election will not be effective and Paine Webber will rely on your standing
order to sell that number of vested shares that is sufficient to obtain
proceeds to satisfy the withholding tax obligation after each vesting
date, as described below. You will pay Paine Webber's usual trade
commission for this sale.

. If you do not make a Section83(b) election, on one of three (3) market
trading days immediately following each vesting date, Paine Webber will
rely on your irrevocable standing order to sell that number of vested
shares that is sufficient to obtain proceeds to satisfy the withholding
tax obligation. You will pay Paine Webber's usual trade commission for
this sale.

. InfoSpace will estimate the amount of taxes to be withheld based on the
closing stock price on the date of vesting. An estimate is needed because
your actual taxable compensation will be determined using the closing
price on the first market trading day following your vesting date. A
schedule will be provided to Paine Webber on the vesting date(s) showing
the shares to be sold for each employee to satisfy the estimated
withholding taxes.

. Shares will be sold in three blocks on the three consecutive trading days
following the vesting date. You will be assigned to one of three trading
groups that will rotate in selling order for each quarterly vesting date.

. Your selling price will be reported by Paine Webber as the average sales
price of the block of shares for the trading group that you were assigned
to. This means that each of the three blocks may have a different selling
price associated with the shares traded to pay withholding taxes and
commissions. However, if you are an executive officer of InfoSpace subject
to the reporting requirements of Section 16 of the Securities Exchange Act
of 1934, as amended, or you are a specifically named "Covered Person"
under the InfoSpace Company Policy Regarding Special Trading Procedures
(Covered Persons will be notified by the Company), your shares will be
sold in one-third increments over the three trading days following vesting
and your selling price will be tracked separately and will be reported by
Paine Webber as your actual sales price for your shares sold.

. You may recognize a short-term capital gain or loss on the shares traded
to pay your withholding taxes and commission based on the difference
between the sales price of your shares sold to cover withholding and the
amount of taxable income recognized on the vesting date (i.e. equal to the
closing price of our stock on the trading day following your vesting
date). Any proceeds from your trade not used to pay withholding taxes or
commissions will be deposited into your Paine Webber account.

. The amount of withholding taxes you owe will be based on the closing price
of our stock on the next market trading day following the vesting date. We
will attempt to estimate the correct number of vested shares to be sold to
cover withholding taxes based on the price of our stock. However, it is
possible that the proceeds obtained from the sale will be either too much
or too little to satisfy the withholding tax obligations. In the event
that excess proceeds are received, the excess will be deposited in your
Paine Webber account. In the event that the proceeds received are
insufficient to cover the withholding taxes, then we reserve the right to
either instruct Paine Webber to sell additional vested shares or deduct
the necessary amount from your wages.

By participating in this exchange and signing the restricted stock agreement
and Irrevocable Standing Order to Sell Shares, you will authorize us and Paine
Webber to take the above actions to pay withholding taxes. In the event there
is not a market in our common stock, we will have the right to make other
arrangements to satisfy the withholding obligations. (Page 33)

22. When can I sell my shares of restricted stock?

The scheduled vesting dates for the restricted stock grants are as follows:
February 27, 2002, May 27, 2002, August 27, 2002, November 27, 2002, February
27, 2003, May 27, 2003, August 27, 2003, and November 27, 2003.

The vested shares (less the shares held back for tax withholding) will be
deposited to your Paine Webber account on the morning of the next trading day
following each vesting date. Once sufficient shares have been sold to cover
your tax obligations and Paine Webber's commission, any remaining shares will
be deposited in your account approximately six business days after the vesting
date. This delay is necessary to allow adequate time for Paine Webber to sell
the shares to pay the taxes and for your account to be reconciled. (Page 24)

23. How do I exchange my options for restricted stock pursuant to the offer?

In connection with the offer, we are providing you a packet of information,
which includes, among other things, a cover letter describing the offer.
Additionally, there will be included an Election Form that Brent Satterlee must
receive by 9:00 p.m., Pacific Standard Time, on November 26, 2001, stating
whether or not you intend to participate in the offer. You may mail your
Election Form to Brent's attention at: 601 108th Avenue N.E., Suite 1200,
Bellevue, Washington 98004. It also is acceptable to fax your signed Election
Form to Brent at (425) 201-6185 on or before the above deadline and mail the
original. If you do not hand it in, or it is not timely received by us, you
will not be able to participate.

We will send an e-mail three (3) business days prior to the expiration of
the offer to confirm whether your Election Form has been received or alerting
you that it has not yet been received. We will send a final confirmation e-mail
following the expiration of the offer to confirm what remaining forms were
received. However, these e-mails do not constitute acceptance of the options
for exchange. (Page 19)

24. When does the offer to exchange expire? Can the offer be extended, and if
so, how will I know if it is extended?

The offer expires on November 26, 2001 at 9:00 p.m., Pacific Standard Time.
Although we do not currently intend to do so, we may, in our discretion, extend
the offer at any time. If the offer is extended we will make a public
announcement of the extension no later than 6:00 a.m. Pacific Standard Time, on
the next business day following the previously scheduled expiration of the
offer period. (Page 19)

25. During what period of time may I withdraw my previously tendered options?

You may withdraw your tendered options at any time before 9:00 p.m., Pacific
Standard Time, on November 26, 2001. If we extend the offer beyond that time,
you may withdraw your tendered options at any time until the extended
expiration of the offer. To withdraw tendered options, you must deliver to
Brent Satterlee in the Bellevue office a completed Notice to Withdraw From the
Offer while you still have the time to withdraw the tendered options. Once you
have withdrawn your options, you may re-tender them only by following the
delivery procedures described in this offer. (Page 20)

26. Do I have to return an election form if I do not want to exchange my
options?

Whether you accept the offer or not, we urge you to complete and deliver the
Election Form to Brent Satterlee by the deadline specified above. Although we
would appreciate receiving your Election Form, if you do not deliver it to us,
you will be deemed to have rejected this offer. (Page 19)

27. What happens to my options if I do not accept the offer or if my options
are not accepted for exchange?

If you do not accept the offer, or if we do not accept all tendered options,
you will keep all of your current options, including any Special Options, and
you will not receive any restricted stock. The options will retain their
current exercise prices and vesting schedule until you exercise them or they
expire by their terms. However, if you currently have incentive stock options
that are eligible to be tendered under this offer and you do not accept the
offer, see Question 19 above. (Page 9)

28. What happens to my options if after I tender my options, I cease to be an
employee of InfoSpace?

If you cease to be an employee of InfoSpace after we accepted and cancelled
your tendered options, you will have no rights with respect to those options
and they will not be reissued and returned to you for any reason. (Page 16)

This offer does not change the "at-will" nature of your employment with us
in any way and your employment may be terminated by us or by you at any time.

29. What happens if an outside party acquires InfoSpace?

If we are acquired prior to the expiration of the offer, you may withdraw
your tendered options and have the rights afforded to you under the particular
stock plan and your existing stock option agreements evidencing those options.

If you continue employment after a buyer acquires control of InfoSpace, the
buyer generally will assume your unvested restricted stock and your vesting
schedule would continue. Rather than receiving shares of stock in InfoSpace,
you would in all likelihood receive shares of stock in the buyer, cash or a
combination of both when you vest. Certain members of senior management who do
not continue employment after a buyer acquires InfoSpace may be entitled to
receive certain accelerated vesting. Your restricted stock agreement will
contain the particular provisions regarding the effect of an acquisition on
your restricted stock. (Page 25)

30. What do we and our board of directors think of this offer to exchange?

Although our board of directors has approved this offer, neither we nor our
board of directors makes any recommendation as to whether you should tender or
refrain from tendering your options. You should evaluate

your situation and consult with your personal tax, financial or legal advisor
to determine whether or not to participate in the exchange. We recommend that
you evaluate current market quotes for our market stock, among other factors,
before deciding whether or not to participate in the exchange. (Page 19)

31. What are the accounting consequences to the Company of making this offer?

InfoSpace will record an expense based on the stock's value on the date of
grant. This amount will be expensed as a compensation expense as the restricted
stock vests. The shares of restricted stock issued in exchange will not be
treated as variable awards for financial accounting purposes. As a result of
this offer, all options that are eligible to be tendered but that are not
tendered and accepted may be treated for financial reporting purposes as
variable awards. This means that we may be required to record non-cash stock
compensation charges reflecting any increases and decreases in the price of
InfoSpace's common stock. The higher the market value of our common stock, the
greater the non-cash stock compensation expense we would have to record. We
would have to continue to reflect the impact of increases and decreases in the
price of InfoSpace's common stock in InfoSpace's statement of operations until
the options are exercised, forfeited or terminated. Options which were eligible
but not tendered in this offer and accepted will retain their original term,
which is generally ten (10) years, subject to earlier expiration of the option
upon the occurrence of certain events, such as the optionee's termination of
employment. (Page 31)

32. Who can I talk to if I have questions about this offer?

All questions should be directed to the Exchange Offer Hotline at
eo@infospace.com or (425) 709-8008. We will attempt to respond to e-mail
inquiries within 24-48 hours.

33. What else should I know about this Offer to Exchange?

We may update this Offer to Exchange in the future by furnishing to
participants an appendix, memorandum, notice or replacement page containing
updated information. We generally will not send you a new Offer to Exchange,
except upon request. Accordingly, you should keep this Offer to Exchange for
future reference.

You should rely on the information incorporated by reference or provided in
this Offer to Exchange or any supplement to this Offer to Exchange. We have not

offer is not permitted. You should not assume that the information in this
Offer to Exchange or any supplement to this Offer to Exchange is accurate as of
any date other than the date on the front of this document.

referring you to those documents. The information incorporated by reference is
considered to be part of this prospectus, and later information filed with the
SEC will update and supersede this information. We incorporate by reference the
documents listed below and any future filings we make with the SEC under

1934 Act or the latest prospectus filed pursuant to Rule 424(a) under the
Securities Act of 1933 (the "1933 Act") which contains, either directly or by
incorporation by reference, audited financial statements for our latest fiscal

CERTAIN RISKS OF PARTICIPATING IN THE OFFER

Participation in the offer involves a number of potential risks, including
those described below. This list and the risk factors under the heading
entitled "Factors Affecting Our Operating Results, Business Prospects and
Market Price of Stock" in InfoSpace's Annual Report on Form 10-K for the fiscal
year ended December 31, 2000, filed on April 2, 2001, and under the heading
entitled "Factors Affecting Future Results" in InfoSpace's Quarterly Report on
Form 10-Q for the quarter ended June 30, 2001, filed on August 13, 2001,
highlight the material risks of participating in this offer. Eligible employees
should carefully consider these risks and are encouraged to speak with an
investment and tax advisor as necessary before deciding to participant in the
offer. In addition, we strongly urge you to read the rest of this Offer to
Exchange, the related letter from Naveen Jain, Chairman and Chief Executive
Officer of InfoSpace, dated October 29, 2001, the Election Form and the Notice
to Withdraw from the Offer and our entire Annual Report on Form 10-K for the
fiscal year ended December 31, 2000 before deciding whether the participate in
the exchange offer.

ECONOMIC RISKS

You may lose the potential benefit of any vested options that you tender in
this offer.

Your shares of restricted stock are scheduled to vest ratably in eight equal
installments every three months commencing February 27, 2002. You will receive
restricted stock with a new vesting schedule and lose the benefit of vesting
that has already occurred with respect to your Eligible Options and you will
receive no restricted stock for the Special Options you tender. You will
generally forfeit any portion of the restricted stock you receive in this offer
that is not vested when your service with us terminates for any reason. In such
case, your unvested restricted stock will expire and will not continue to vest.
If your service with us is terminated for any reason prior to February 27,
2002, you generally will forfeit all of your restricted stock. If your service
with us is terminated for any reason prior to November 27, 2003, the last
regularly scheduled vesting date of the restricted stock (or later, in the case
of certain leaves of absence), you may lose the potential benefit of any vested
options you tender in this offer.

You may benefit from an increase in the trading price of our common stock to a
lesser extent if you tender your options in this offer.

If the trading price of our common stock increases after this offer, of
which we can give you no assurance whatsoever, you may benefit to a lesser
extent if you tender your options. You are eligible to receive one (1) share of
restricted stock for every four (4) shares of common stock covered by your
Eligible Options and you are not eligible to receive any shares of restricted
stock for any shares covered by your Special Options. If the trading price of
our common stock increases above the exercise price of your tendered options,
because of the higher number of option shares, you may benefit more from
holding the options. We advise you to consult with your financial advisor
regarding the potential benefits of holding your options at different trading
prices of our common stock.

TAX-RELATED RISKS

You may incur tax liability in connection with receiving your restricted stock
but never recognize any benefit from your restricted stock, or incur tax
liability in excess of the amount you receive upon sale of your restricted
stock.

If you do not make an election under Section 83(b) of the Internal Revenue
Code, upon the vesting of your restricted stock, you will be required to
recognize additional income in an amount equal to the fair market value of the
restricted stock that vests, determined on the day after the shares vest. If
the trading price of our common stock decreases after a vesting date and your
shares are subsequently sold, you may receive an amount from the sale of your
restricted stock that is less than your tax liability.

If you make a Section 83(b) election, you will be required to recognize
taxable income at the time you receive your restricted stock in an amount equal
to the fair market value of the restricted stock you receive on that date. If
you make a Section 83(b) election and subsequently forfeit your shares of
restricted stock, you will receive nothing from the forfeiture of your
restricted stock to offset your tax liability. Also, if the trading price of
our common stock decreases after you receive your restricted stock, and your
restricted stock subsequently vests, you may receive an amount from the sale of
your restricted stock that is less than your tax liability.

Even if you elect not to participate in the exchange, your incentive stock
options may be affected.

We believe that you will not be subject to current U.S. federal income tax
if you do not elect to participate in the exchange. We also believe that the
exchange will not change the U.S. federal income tax treatment of subsequent
grants and exercises of your incentive stock options (and sales of shares
acquired upon exercises of such options) if you do not participate in the
exchange.

However, the Internal Revenue Service may characterize our offer to you as a
"modification" of those incentive stock options, even if you decline the offer.
A successful assertion by the Internal Revenue Service that your incentive
stock options are modified would extend your required holding period with
respect to the shares purchased under those options in order to qualify all of
the gain on a subsequent sale of those shares as long-term capital gain. That
extended holding period for long-term capital gain would require that any
taxable sale or disposition of the shares not take place until the later of (i)
two (2) years from the date of the deemed modification of your incentive stock
options, or (ii) one (1) year from the date of the option exercise for those
shares. In addition, such a deemed modification may also cause a portion of
your incentive stock options to be treated as non-qualified stock options upon
exercise.

BUSINESS-RELATED RISKS

For a description of risks related to InfoSpace's business, please see
Section 19 of this Offer to Exchange.

THE OFFER

1. Eligibility.

You are an employee eligible to participate in the offer (an "Eligible
Employee") if:

(1) you are a full-time (30 hours or more per week) U.S.-based employee
of InfoSpace, Inc. or Saraide Inc. (the "Company's U.S. subsidiaries")
working in the U.S. and are paid through U.S. payroll;

(2) you were hired on or before October 26, 2001;

(3) you are employed by InfoSpace or one of its U.S. subsidiaries on the
date this offer is made and remain employed as of the date the tendered
options are accepted for exchange and the date the restricted stock is
granted; and

(4) you hold one or more eligible options to purchase InfoSpace common
stock granted on or after February 6, 2001 under the 2001 Nonstatutory Stock
Option Plan (the "2001 Plan") or the Restated 1996 Flexible Stock Incentive
Plan (the "1996 Plan").

You are not eligible to participate in the offer if:

(1) you are a non-U.S. based employee of InfoSpace or one of its
subsidiaries;

(2) you were hired after October 26, 2001;

(3) you are employed by InfoSpace or a U.S. subsidiary of InfoSpace, but
you are paid through payroll outside the U.S. or only work part-time;

(4) you are a non-employee member of our board of directors;

(5) you are a consultant or contractor; or

(6) you are not an Eligible Employee as described above.

If you meet the eligibility requirements, but you are on an approved leave
of absence during the election period, you are still eligible to participate in
the offer. However, if you are absent for more than 50% of any given vesting
period due to being on an approved leave of absence you would not vest for that
period, and the vesting of your restricted stock will be deferred. For any such
vesting period in which an employee does not vest due to having been on an
approved leave of absence for more than 50% of that vesting period, an
additional vesting period will be added on to the end of the vesting schedule
for that employee subject to the terms and conditions of the rest of this Offer
to Exchange.

2. Number of options; expiration date.

Subject to the terms and conditions of the offer, we will exchange all
outstanding, unexercised Eligible Options held by Eligible Employees that are
properly tendered in accordance with Section 4 and not validly withdrawn before
the "expiration date," as defined below, in return for shares of "restricted
stock," as defined in Section 9. We are offering to exchange all stock options
having an exercise price of $3.00 or more that were granted under our 2001 Plan
and our 1996 Plan on or after February 6, 2001 ("Eligible Options") to Eligible
Employees. In return for your tender of Eligible Options, you will receive a
certain number of shares of restricted stock.

Although we will not issue restricted stock in exchange for any "Special
Options" you hold, if you elect to accept this offer, you must return all your
Special Options for cancellation. The Special Options are all outstanding
options you hold, other than Eligible Options, with exercise prices equal to or
greater than $3.00 per share granted under:

. the 1996 Plan,

. the 2001 Plan,

. the Go2Net Inc. 1996 Stock Option Plan,

. the Go2Net Inc. 2000 Stock Option Plan,

. the Silicon Investor, Inc. 1996 Stock Plan,

. the WEB 21 Stock Option Plan,

. the Authorize.Net Corporation 1999 Stock Incentive Plan,

. the IQC Corporation Option to Purchase Common Stock,

. the SaveSmart, Inc. 1997 Equity Incentive Plan,

. the Saraide.com Inc. 1998 Equity Incentive Plan,

. the InfoSpace, Inc. and Saraide Inc. 2000 Stock Plan, and

. the INEX Corporation Share Option Plan,

regardless of when granted or whether vested or unvested. If you elect to
participate in the offer, you will be required to tender all Special Options
you hold. You will not receive any restricted stock in exchange for the Special
Options. However, if you elect to participate in the exchange, you will be
eligible to receive a supplemental restricted stock grant (the "Supplemental
Grant") granted by the board of directors of InfoSpace, in its sole discretion.
The number of shares of restricted stock granted as Supplemental Grants, if
any, will vary among employees. The terms of the Supplemental Grants will be
the same as the terms of the restricted stock granted in exchange for the
Eligible Options. Eligible Employees must participate in the exchange offer in
order to be eligible to receive a Supplemental Grant.

You will receive one share of restricted stock for every four (4) shares
covered by an Eligible Option that you tender. All fractional amounts will be
rounded up. For example, assume that you tender an Eligible Option covering
3,750 shares. 3,750 shares divided by 4 equals 937.5. The restricted stock
grant would be rounded up to 938 shares. We will not accept partial tenders of
options. Therefore, you may tender options for all or none of the shares
subject to your Eligible Options. Participating employees also will be required
to surrender, in addition to the Eligible Options, all of their Special
Options. No restricted stock will be granted in exchange for the Special
Options. We presently expect to cancel all tendered options on or about
November 28, 2001.

If you cease to be an employee of InfoSpace prior to the expiration of the
offer, you may withdraw your tendered options and exercise them to the extent
they are vested and in accordance with their terms. In this case, you will not
receive any restricted stock. If you cease to be an employee of InfoSpace after
we have accepted and cancelled your tendered options, you will have no rights
with respect to those options and they will not be reissued and returned to you
for any reason. In this case, you will be entitled to keep any vested shares of
restricted stock as of your date of termination. These forfeiture provisions
will apply regardless of whether you quit with or without good reason, we
terminate your employment with or without cause or your employment is
terminated because of death or disability. This offer does not change the
"at-will" nature of your employment with us in any way and your employment may
be terminated by us or by you at any time.

The term "expiration date" means 9:00 p.m., Pacific Standard Time, on
November 26, 2001, unless and until we, in our sole discretion, have extended
the period of time during which the offer will remain open, in

which event the term "expiration date" refers to the latest time and date at
which the offer, as so extended, expires. See Section 16 of this Offer to
Exchange for a description of our rights to extend, delay, terminate and amend
the offer.

If we decide to take any of the following actions, we will publish notice or
otherwise inform you in writing of such action:

. we increase or decrease the amount of consideration offered for the
options,

. we decrease the number of options eligible to be tendered in the offer, or

. we increase the number of options eligible to be tendered in the offer by
an amount that exceeds 2% of the shares issuable upon exercise of the
options that are subject to the offer immediately prior to the increase.

If the offer is scheduled to expire at any time earlier than the tenth
(10th) business day from, and including, the date that notice of the increase
or decrease is first published, sent or given in the manner specified in
Section 16 of this Offer to Exchange, we will extend the offer so that the
offer is open at least ten (10) business days following the publication,
sending or giving of notice.

We will also notify you of any other material change in the information
contained in this Offer to Exchange.

For purposes of the offer, a "business day" means any day other than a
Saturday, Sunday or federal holiday and consists of the time period from 12:01
a.m. through 12:00 midnight, Eastern Standard Time.

3. Purpose of the offer.

We previously issued the Eligible Options to:

. provide our employees with additional incentives and to promote the
success of our business, and

. encourage our employees to continue their employment with us.

Our board of directors has authorized this exchange in order to provide
Eligible Employees an incentive for their continued efforts and dedication. As
a company, we are committed to employee ownership because it helps us attract
and retain the best and brightest employees.

We continually evaluate strategic opportunities as they arise, including
business combination transactions, capital infusions and the purchase or sale
of assets. We also routinely grant options to our employees and non-employee
directors and offer stock pursuant to our 1998 Employee Stock Purchase Plan.
Subject to the foregoing, and except as otherwise disclosed in this Offer to
Exchange or in our filings with the SEC, we presently have no definitive plans
or binding proposals that relate to or would result in:

(a)any extraordinary transaction, such as a merger, reorganization or
liquidation;

(b)any purchase, sale or transfer of a material amount of assets of our
assets or the assets of our subsidiaries;

(c)any material change in our present dividend policy or in our
indebtedness;

(d)any change in our present board of directors or management;

(e)any material changes in our corporate structure or business;

(f)our common stock not being authorized for quotation in an automated
quotation system operated by a national securities exchange;

(g)our common stock becoming eligible for termination of registration
pursuant to Section 12(g)(4) of the Securities Exchange Act of 1934;

(h)the suspension of our obligation to file reports with the SEC pursuant
to Section 15(d) of the Securities Exchange Act of 1934; or

(i)any change in our certificate of incorporation or bylaws or any actions
which may impede the acquisition of control of us by an person.

NEITHER WE NOR OUR BOARD OF DIRECTORS MAKES ANY RECOMMENDATION AS TO WHETHER
YOU SHOULD TENDER OR NOT TENDER YOUR OPTIONS, NOR HAVE WE AUTHORIZED ANY PERSON
TO MAKE ANY SUCH RECOMMENDATION. YOU ARE URGED TO EVALUATE CAREFULLY ALL OF THE
INFORMATION IN THIS OFFER TO EXCHANGE, THE LETTER FROM NAVEEN JAIN DATED
OCTOBER 29, 2001, THE ELECTION FORM, AND THE NOTICE TO WITHDRAW FROM THE OFFER
AND TO CONSULT YOUR OWN INVESTMENT AND TAX ADVISORS. YOU MUST MAKE YOUR OWN
DECISION WHETHER OR NOT TO TENDER YOUR OPTIONS FOR EXCHANGE.

4. Procedures for tendering options.

The delivery of all documents, including Election Forms and any Notice to
Withdraw from the Offer, is at your risk. We intend to confirm the receipt of
your Election Form within three business days prior to the expiration of the
offer and we will send a final confirmation e-mail following the expiration of
the offer to confirm what remaining forms were received. However, these e-mails
do not constitute acceptance of the options for exchange. If you have not
received such a confirmation of receipt, it is your responsibility to ensure
that we have received your Election Form.

Determination of Validity; Rejection of Options; Waiver of Defects; No
Obligation to Give Notice of Defects.

We will determine, in our discretion, all questions as to the form of
documents and the validity, form, eligibility, including time of receipt, and
acceptance of any tender of options. Our determination of these matters will be
final and binding on all parties. Although we anticipate that we will accept
properly and timely tendered options that are not validly withdrawn, we reserve
the right to reject any or all tenders of options for any reason, including
tenders of options that we determine are not in appropriate form or that we
determine are unlawful to accept. We also reserve the right to waive any of the
conditions of the offer or any defect or irregularity in any tender of any
particular options or for any particular Eligible Employee, provided that if we
grant any such waiver, it shall be granted to all Eligible Employees and
tenders of options. No tender of options will be deemed to have been properly
made until all defects or irregularities have been cured by the tendering
Eligible Employee or waived by us. Neither we nor any other person is obligated
to give notice of any defects or irregularities in tenders, nor will anyone
incur any liability for failure to give any notice. This is a one-time offer,
and we will strictly enforce the offer period, subject only to any extension
which we may grant in our sole discretion.

Our Acceptance Constitutes an Agreement.

Your tender of options pursuant to the procedures described above
constitutes your acceptance of the terms and conditions of the offer. OUR
ACCEPTANCE FOR EXCHANGE AND CANCELLATION OF THE

OPTIONS TENDERED BY YOU THROUGH THE OFFER WILL CONSTITUTE A BINDING AGREEMENT
BETWEEN US AND YOU UPON THE TERMS AND SUBJECT TO THE CONDITIONS OF THE OFFER.
As noted above, we reserve the right to reject any or all tenders of options
for any reason, including tenders of options that we determine are not in
appropriate form or that we determine are unlawful to accept.

Subject to our rights to extend, terminate and amend the offer, we presently
expect that we will accept all properly tendered options that have not been
validly withdrawn promptly after the expiration of the offer.

5. Withdrawal rights and change of election.

You may only withdraw your tendered options or change your election in
accordance with the provisions of this section.

You may withdraw your tendered options at any time before 9:00 p.m., Pacific
Standard Time, on November 26, 2001. If we extend the offer beyond that time,
you may withdraw your tendered options at any time until the extended
expiration of the offer. We expect to accept all properly tendered options
promptly after the expiration of the offer on November 26, 2001, and we expect
to cancel all accepted options on or about November 28, 2001. If, however, we
have not accepted your tendered options for exchange by 9:00 p.m., Pacific
Standard Time, on December 24, 2001, you may withdraw your tendered options at
any time after December 24, 2001, until they are accepted and cancelled.

To validly withdraw tendered options, you must deliver to InfoSpace,
Attention: Brent Satterlee via facsimile (425-201-6185) or hand delivery, in
accordance with the procedures listed in Section 4 above, a signed and dated
Notice to Withdraw from the Offer, with the required information, while you
still have the right to withdraw the tendered options.

If you first decline to participate in the offer and then decide to
participate, you must deliver a new Election Form to InfoSpace, Attention:
Brent Satterlee via facsimile (425-201-6185) or hand delivery, in accordance
with the procedures listed in Section 4 above prior to the expiration date. If
you deliver a new Election Form that is properly signed and dated, it will
replace any previously submitted Election Form, which will be disregarded. The
new Election Form must be signed and dated.

Except as described in the following sentences of this paragraph, the
Election Form and the Notice to Withdraw from the Offer must be executed by the
Eligible Employee whose name appears on the option agreement or agreements
evidencing such options. If the Eligible Employee's name has legally been
changed since the signing of the option agreement, the Eligible Employee must
submit proof of the legal name change. If the signature is by a trustee,
executor, administrator, guardian, attorney-in-fact, officer of a corporation
or another person acting in a fiduciary or representative capacity, the
signer's full title and proper evidence of the authority of such person to act
in that capacity must be indicated.

You may not rescind any withdrawal, and any options you withdraw will
thereafter be deemed not properly tendered for purposes of the offer, unless
you properly re-tender those options before the expiration date by following
the procedures described in Section 4.

Neither we nor any other person is obligated to give notice of any defects
or irregularities in any Notice to Withdraw from the Offer or any new or
amended Election Form, nor will anyone incur any liability for failure to give
any notice. We will resolve, in our discretion, all questions as to the form
and validity, including time of receipt, of any Notices to Withdraw from the
Offer and any new or amended Election Forms. Our determination of these matters
will be final and binding.

6. Acceptance of options for exchange and issuance of restricted stock.

Upon the terms and conditions of the offer and promptly following the
expiration date, we will accept for exchange and will cancel those Eligible
Options that are properly tendered and not validly withdrawn before the

expiration date. Once the options are cancelled, you will no longer have any
rights with respect to those options. Subject to the terms and conditions of
this offer, if your options are properly tendered and accepted for exchange,
these options will be cancelled promptly after the date of our acceptance,
which we anticipate to be on or about November 28, 2001, and we will forward to
you, as soon as practicable, a restricted stock agreement for execution in
connection with the issuance to you of restricted stock.

The restricted stock will be granted under the 2001 Plan on November 28,
2001, unless we extend this Offer to Exchange or unless we decide to reject all
tendered options. We expect to distribute the restricted stock agreements
promptly after expiration of this Offer to Exchange and after we have accepted
and cancelled the tendered options. Your award of restricted stock will be
evidenced by a restricted stock agreement between you and us, but you will not
receive a stock certificate for the restricted stock. Until the restricted
stock vests, it will be held in the custody of Paine Webber.

Generally, as the shares vest, they will be deposited into your account with
Paine Webber, subject to payment of applicable withholding taxes. Following
each vesting date, if you are still employed by us, have signed the restricted
stock agreement and related documents and have opened your account with Paine
Webber, 12.5% of the shares of your original award of restricted stock will be
deposited into your Paine Webber account within approximately six business
days, subject to payment of applicable withholding taxes.

We will not accept partial tenders of your Eligible Options or Special
Options. However, you may tender the remaining portion of an option which you
have partially exercised. Accordingly, to participate in the offer, you must
tender all of your unexercised Eligible Options and Special Options whether or
not such options are partially exercised.

InfoSpace will not issue any new options to Eligible Employees for a period
of at least six months from the date of the restricted stock grant, regardless
of whether or not the Eligible Employee participates in the offer. We will
defer the grant of new options to Eligible Employees because it is necessary
for us to do so to avoid incurring compensation expense because of accounting
rules that could apply to these interim option grants as a result of the offer.
Therefore, Eligible Employees generally will not be eligible to receive any new
option grants until the 2002 annual review in October 2002.

If you do not accept the offer, or if we do not accept any returned options,
you will keep all of your current options, including any Special Options, and
you will not receive any restricted stock. The options will retain their
current exercise prices and vesting schedule until you exercise them or they
terminate or expire by their terms.

Within three (3) business days prior to the expiration of the offer, we
intend to e-mail you a confirmation of receipt. However, this is not by itself
an acceptance of your options for exchange. For purposes of the offer, we will
not be deemed to have accepted your options for exchange until such time as of
when we have given oral or written notice to the Eligible Employees generally
of such acceptance of such options for exchange, which notice may be made by
press release. Subject to our rights to extend, terminate and amend the offer,
we presently expect that we will accept all properly tendered options that are
not validly withdrawn promptly after the expiration of the offer. Options
accepted for exchange will be cancelled on the Cancellation Date, which we
presently expect to be on or about November 28, 2001. We currently anticipate
announcing our decision to accept or reject the exchange offers on or about
November 28, 2001.

7. Conditions of the offer.

Notwithstanding any other provision of the offer, we will not be required to
accept any options tendered for exchange, and we may terminate or amend the
offer, or postpone our acceptance and cancellation of any options tendered for
exchange, in each case, subject to Rule 13e-4(f)(5) under the Securities
Exchange Act, if at any time on or after October 29, 2001, and prior to the
Expiration Date, any of the following events has occurred, or has been
determined by us to have occurred, and, in our reasonable judgment in any case
and regardless of the circumstances giving rise to the event, including any
action or omission to act by us, the occurrence of such event

or events makes it inadvisable for us to proceed with the offer or with such
acceptance and cancellation of options tendered for exchange:

. there shall have been threatened or instituted or be pending any action or
proceeding by any governmental, regulatory or administrative agency or
authority that directly or indirectly challenges the making of the offer,
the acquisition of some or all of the tendered options pursuant to the
offer, the issuance of restricted stock, or otherwise relates in any
manner to the offer, or that, in our reasonable judgment, could materially
and adversely affect our business, condition, income, operations or
prospects or materially impair the contemplated benefits of the offer to
InfoSpace;

. there shall have been any action threatened, pending or taken, or approval
withheld, or any statute, rule, regulation, judgment, order or injunction
threatened, proposed, sought, promulgated, enacted, entered, amended,
enforced or deemed to be applicable to the offer or InfoSpace, by any
court or any authority, agency or tribunal that, in our reasonable
judgment, would or might directly or indirectly:

(i) make the acceptance for exchange of, or issuance of restricted stock
for, some or all of the tendered options illegal or otherwise restrict
or prohibit consummation of the offer or that otherwise relates in any
manner to the offer;

(ii)delay or restrict our ability, or render us unable, to accept for
exchange, or issue restricted stock for, some or all of the tendered
options;

(iii)materially impair (such as by increasing the accounting or other costs
of the offer to InfoSpace) the contemplated benefits of the offer to
InfoSpace, where the contemplated benefits include the opportunity for
us to align employee and stockholder interests and offer Eligible
Employees a valuable incentive to stay with InfoSpace and to achieve
high levels of performance; or

(iv)materially and adversely affect InfoSpace's business, condition,
income, operations or prospects or materially impair the contemplated
benefits of the offer to InfoSpace;

. a tender or exchange offer for some or all of our shares, or a merger or
acquisition proposal for InfoSpace, shall have been proposed, announced or
made by another person or entity or shall have been publicly disclosed;

. the number of tendered options underlying shares of our common stock is
not sufficient to make the exchange worthwhile to InfoSpace; specifically,
we will not be obligated to cancel any options and grant any restricted
stock pursuant to this offer if optionholders as a group tender options to
purchase less than 46,755,234 shares of our common stock (95% of the
aggregate shares underlying the Eligible Options and Special Options).
However, we may choose to cancel options and grant restricted stock
pursuant to this offer if options to purchase less than 46,755,234 shares
of our common stock are tendered.

. any change or changes shall have occurred in InfoSpace's business,
condition, assets, income, operations, prospects or stock ownership that,
in our reasonable judgment, is or may be material to InfoSpace or may
materially impair the contemplated benefits of the offer to InfoSpace;

. any general suspension of trading in, or limitation on prices for,
securities on any national securities exchange, the Nasdaq stock market or
the over-the-counter market; or

. any actual or anticipated change in United States generally accepted
accounting principles which could materially and adversely effect the
manner in which we are required for financial accounting purposes to
account for the offer.

The conditions to the offer are for our benefit. We may assert them in our
discretion regardless of the circumstances giving rise to them before the
expiration date. We may waive them, in whole or in part, at any time and from
time to time prior to the expiration date, in our discretion, whether or not we
waive any other condition to the offer. Our failure at any time to exercise any
of these rights will not be deemed a waiver of any such rights. The waiver of
any of these rights with respect to particular facts and circumstances will not
be deemed a waiver with respect to any other facts and circumstances. Any
determination we make concerning the events described in this Section 7 will be
final and binding upon all persons.

WE RECOMMEND THAT YOU EVALUATE CURRENT MARKET QUOTES FOR OUR COMMON STOCK,
AMONG OTHER FACTORS, BEFORE DECIDING WHETHER OR NOT TO TENDER YOUR OPTIONS.

9. Source and amount of consideration; terms of restricted stock.

Consideration.

We will issue shares of common stock subject to certain vesting restrictions
(the "restricted stock") under our 2001 Plan in exchange for the Eligible
Options properly tendered to and accepted for exchange and cancelled by us.
Participating employees will also be required to surrender any Special Options.
We will cancel all surrendered Special Options but no restricted stock will be
granted for the Special Options. We will issue one share of restricted stock
for each four shares of common stock underlying the tendered Eligible Options
which we accept and cancel in accordance with the terms of this offer with
fractional shares rounded up to the nearest whole share. In addition, Eligible
Employees who participate in the exchange will be eligible to receive a
Supplemental Grant of restricted stock under the 2001 Plan, as determined in
the sole discretion of the board of directors. If we receive and accept tenders
of all Eligible Options from all Eligible Employees, subject to the terms and
conditions of this offer, we will issue 7,416,038 shares of restricted stock in
exchange for the shares underlying the Eligible Options. These shares would
equal approximately 3% of the total shares of our common stock outstanding as
of October 25, 2001.

Terms of Restricted Stock.

The following description of the terms of the restricted stock is a summary
and is not complete. The description is subject to, and qualified in its
entirety by reference to, all provisions of the 2001 Plan and the forms of
restricted stock agreement. The 2001 Plan, as amended, and the forms of
restricted stock agreement have been filed with the SEC as exhibits to the
Schedule TO. Please contact us by email at eo@infospace.com or at 601 108/th/
Avenue N.E., Suite 1200, Bellevue, Washington 98004, Attention: Brent
Satterlee, (telephone: 425-709-8008), to receive a copy of the 2001 Plan or the
restricted stock agreements. We will promptly furnish you with copies of these
documents at our expense.

General.

Awards of restricted stock under the 2001 Plan may be made to employees and
consultants of InfoSpace and its subsidiaries. At present, 25,000,000 shares of
common stock are reserved for issuance under our 2001 Plan. Under the terms of
the 2001 Plan, the shares of common stock underlying an option cancelled as
part of this offer are available for subsequent grants under the 2001 Plan. We
have amended the 2001 Plan in connection with this offer, a copy of which is
attached to the Schedule TO as Exhibit (d)(1).

The restricted stock issued under the 2001 Plan will be evidenced by a
restricted stock agreement between us and each Eligible Employee whose tendered
Eligible Options are accepted and cancelled in the offer. The restricted stock
agreement will contain the vesting provisions and other restrictions applicable
to the restricted stock to be issued to each such Eligible Employee. The shares
of restricted stock will be subject to forfeiture and other restrictions until
the shares vest. These restrictions include prohibitions against sale,
assignment, transfer, conveyance, pledge, hypothecation, gift or other
encumbrance or disposition.

We will issue in your name the number of shares of restricted stock that you
are entitled to receive in connection with the offer. Until the shares have
vested in accordance with the restricted stock agreement, Paine Webber will
hold the certificates representing the unvested portion of your restricted
shares in their custody. On each vesting date, subject to the terms and
conditions of the 2001 Plan and your restricted stock agreement, after you have
provided for the payment to us of any required federal and state income and
withholding taxes with respect to the vested portion of the restricted stock by
execution of an Irrevocable Standing Order to Sell Shares with Paine Webber, we
will deliver to your Paine Webber account the vested portion of the restricted
stock issued to you pursuant to the offer. You will have dividend, voting and
other stockholder rights with respect to all of the restricted stock, even
though the stock certificate representing the unvested portion of the
restricted stock is held in a separate account in the custody of Paine Webber,
until you vest in that portion of the restricted stock. In addition, we will
send you all notices of meetings, proxy statements, proxies and other materials
distributed to our stockholders. However, if you do not vest in the unvested
portion of the restricted stock and it is forfeited to us, you will lose all
stockholder rights with respect to those shares, and you will not be sent
notices of meetings, proxy statements or other materials distributed to our
stockholders unless you otherwise continue to hold shares of our common stock.

You may generally sell your shares once they have become vested pursuant to
the terms of your restricted stock grant and the terms of the 2001 Plan.
Included with the offering materials will be information and instructions
regarding setting up your account with Paine Webber. We anticipate that the
vested shares (less the shares held back for tax withholding) will be deposited
to your Paine Webber account on the morning of the next trading day following
each vesting date. Once sufficient shares have been sold to cover your tax
obligations and Paine Webber's commission, any remaining shares will be
deposited in your account approximately six business days after the vesting
date. This delay is necessary to allow adequate time for Paine Webber to sell
the shares to pay the taxes and for your account to be reconciled.

Note: If you are an executive of InfoSpace subject to the reporting
requirements of Section 16 of the Securities Act of 1934, as amended, or you
are a specifically named "Covered Person'' under the InfoSpace Company Policy
Regarding Special Trading Procedures, you may be required to file with the SEC
a 10b5-1 trading plan in lieu of signing and delivering an Irrevocable Standing
Order to Sell Shares.

Vesting; Forfeiture.

The shares of restricted stock will vest over a two-year period that will
begin on the exchange date (assuming your continued employment and other
conditions to vesting are met). 12.5% of the shares will vest every three-month
period beginning on February 27, 2002 (February 27, 2002, May 27, 2002, August
27, 2002, November 27, 2002, February 27, 2003, May 27, 2003, August 27, 2003
and November 27, 2003). In the event a three-month amount is a fraction, we
will round the number up to the nearest whole number. For example, if you
receive 10,500 shares of restricted stock, 1,313 shares will vest in each of
the first seven three-month periods and

1,309 shares will vest in the last three-month period. (10,500 divided by 8
equals 1312.5, which rounds up to 1,313 shares per three-month period. After
the first seven three-month periods, 9,191 shares would have vested and the
remaining 1,309 shares would vest in the last three-month period.) This vesting
schedule will apply to the shares of restricted stock regardless of whether or
not the options exchanged in this offer had already vested. Unvested shares of
restricted stock are subject to forfeiture by you as described below.

In the event you terminate your employment with us, we terminate your
employment with or without cause or your employment is terminated because of
your death or disability, you generally will forfeit to us all unvested shares
of restricted stock. For example, assume you receive 10,000 shares of
restricted stock in this offer. One year later, you terminate your employment
and at that time, 5,000 shares of restricted stock have vested. This means that
the remaining 5,000 shares of unvested restricted stock are forfeited. You will
no longer have any rights whatsoever to shares of restricted stock that are
forfeited to us. This forfeiture is what makes the stock restricted.

If you are absent for more than 50% of any given vesting period due to being
on an approved leave of absence, the vesting of your restricted stock will be
suspended for that period -- i.e., you would not receive any vesting for that
period. For any such vesting period in which an employee does not vest due to
having been on an approved leave of absence for more than 50% of that vesting
period, an additional vesting period will be added on to the end of the vesting
schedule for that employee subject to the terms and conditions of the Offer to
Exchange. For example, assume you are employed full-time from the grant date
then go out on an approved leave of absence on February 1, 2002 and return to
full-time work with the Company on May 1, 2002. You would vest for the period
ending on February 27, 2002 because you worked for more than 50% of that
vesting period. You would not vest for the period ending on May 27, 2002
because you would have been on leave for more than 50% of the vesting period.
Instead, an additional vesting period would be added following November 27,
2003 (the last scheduled vesting date) and you would be scheduled to be 100%
vested on February 27, 2004 assuming all other conditions to vesting are met.

Change of Control.

If we are acquired prior to the expiration of the offer, you may withdraw
your tendered options and have the rights afforded you under the particular
stock plan and your existing stock option agreements evidencing those options.

If in the future an outside party, or a "buyer," acquires control of
InfoSpace, the buyer may assume your unvested restricted stock or you may
receive accelerated vesting, depending on the following circumstances:

. If you continue employment with the buyer, your vesting schedule generally
will continue. The difference is that rather than receiving shares of
common stock in InfoSpace as you vest, you may receive either shares of
stock in the buyer or cash as you vest. The amount of stock or cash you
receive will be based on the per share amounts paid by the buyer to the
InfoSpace stockholders in connection with the buyer's acquisition of
InfoSpace. In other words, your restricted shares would be converted into
a right to receive what the InfoSpace stockholders received in the
acquisition. In all likelihood, this would either be stock in the buyer,
cash or a combination of both. The actual amounts you receive would be
subject to the appropriate exchange ratios that are determined in the
acquisition.

. In addition, if you are currently an executive officer of InfoSpace who is
subject to the reporting requirements of Section 16 of the Securities
Exchange Act, you will be entitled to accelerated vesting of any unvested
restricted stock if your employment is terminated as a result of an
involuntary termination within 24 months following a change of control of
InfoSpace.

Your restricted stock agreement contains the provisions, if any, regarding the
effect of a change of control on your restricted stock.

PLEASE BE AWARE THAT THE DATES LISTED ABOVE AND THE DESCRIPTION OF POTENTIAL
BUYERS ARE ONLY BEING USED AS EXAMPLES. WE ARE NOT MAKING ANY REPRESENTATIONS,
WARRANTIES, COVENANTS OR STATEMENTS REGARDING YOUR EMPLOYMENT OR THAT AN
ACQUISITION OF INFOSPACE WILL OR WILL NOT OCCUR IN THE FUTURE.

Tax Consequences.

You should refer to Section 15 of this Offer to Exchange for a discussion of
U.S. federal tax consequences resulting from the exchange of options for
restricted stock.

Other than as set forth above or periodic purchases of our common stock
pursuant to our 1998 Employee Stock Purchase Plan and grants of stock options
in the ordinary course to employees who are not executive officers, there have
been no transactions in options to purchase our common stock or in our common
stock that were effected during the past sixty (60) days by InfoSpace or, to
our knowledge, by any current executive officer, director, affiliate or
subsidiary of InfoSpace.

None of our executive officers or directors have as yet indicated their
intention to tender their options in the offer, other than:

. Edmund O. Belsheim, our President and Chief Operating Officer, and

. Tammy D. Halstead, our Chief Financial Officer.

13. Status of options acquired by us in the offer; accounting consequences
of the offer.

Options we acquire through the offer will be cancelled and the shares
subject to those options granted under the 1996 Plan and 2001 Plan will be
returned to the applicable pool of shares available for grants under the 1996
Plan and the 2001 Plan. To the extent these shares are not issued as restricted
stock in connection with the offer under the 2001 Plan, the shares will be
available for future awards to employees and other eligible plan participants
under the 1996 Plan and the 2001 Plan without further stockholder action,
except as required by applicable law or the rules of the Nasdaq National Market
or any other securities quotation system or any stock exchange on which our
shares are then quoted or listed.

The exchange and cancellation of tendered options and the subsequent
issuance of restricted stock will result in the recognition of a compensation
cost by us. The compensation cost is measured as the quoted market price of our
common stock on the date a share of restricted stock is granted. As shares
vest, we will recognize compensation costs. The expense must be amortized
against our earnings over the vesting period of the restricted stock. The
shares of restricted stock issued in the exchange will not be treated as
variable awards for financial accounting purposes.

As a result of this offer, all options that are eligible to be tendered but
that are not tendered and accepted may be treated for financial reporting
purposes as variable awards. This means that we may be required to record
non-cash stock compensation charges reflecting any increases and decreases in
the price of InfoSpace's common stock. The higher the market value of our
common stock, the greater the non-cash stock compensation expense we would have
to record. We would have to continue to reflect the impact of increases and
decreases in the price of InfoSpace's common stock in InfoSpace's statement of
operations until the options are exercised, forfeited or terminated. Options
which were eligible but not tendered in this offer and accepted will retain
their original term, which is generally ten (10) years, subject to earlier
expiration or termination of the option upon the occurrence of certain events,
such as the optionee's termination of employment.

14. Legal matters; regulatory approvals.

We are not aware of any license or regulatory permit that appears to be
material to our business that might be adversely affected by our exchange of
options and issuance of restricted stock as contemplated by the offer, or of
any approval or other action by any government or governmental, administrative
or regulatory authority or agency, domestic or foreign, that would be required
for the acquisition or ownership of our options as contemplated herein. Should
any such approval or other action be required, we presently contemplate that we
will seek such approval or take such other action. We cannot assure you that
any such approval or other action, if needed, could be obtained or what the
conditions imposed in connection with such approvals would entail or whether
the failure to obtain any such approval or other action would result in adverse
consequences to our business. Our obligation under the offer to accept tendered
options for exchange and to issue new options for tendered options is subject
to the conditions described in Section 7.

15. Material U.S. federal income tax consequences.

The following is a general summary of the material U.S. federal income tax
consequences of the exchange of options pursuant to the offer. This discussion
is based on the Internal Revenue Code, its legislative history, Treasury
Regulations thereunder and administrative and judicial interpretations thereof
as of the date of the offer, all of which are subject to change, possibly on a
retroactive basis. This summary does not discuss all of the tax consequences
that may be relevant to you in light of your particular circumstances, nor is
it intended to be applicable in all respects to all eligible employees.

WE ADVISE ALL ELIGIBLE EMPLOYEES WHO MAY CONSIDER EXCHANGING THEIR OPTIONS
TO MEET WITH THEIR OWN TAX ADVISORS WITH RESPECT TO THE FEDERAL, STATE, LOCAL
AND FOREIGN TAX CONSEQUENCES OF PARTICIPATING IN THE OFFER.

Issuance of Restricted Stock.

If you do not make an election under Section 83(b) of the Internal Revenue
Code, you will have no taxable income at the time we grant you the restricted
stock. Instead, you will recognize ordinary income when (and if) the restricted
stock vests and no longer is subject to forfeiture. If you make a Section 83(b)
election by filing the Section 83(b) election form. The election must be made
within thirty days of the grant of restricted stock by sending a Section 83(b)
election to the Internal Revenue Service. You must also supply a copy to
InfoSpace (Attention: Payroll Department) along with a check to cover the
withholding taxes, you recognize ordinary income at the time of grant of the
restricted stock. However, if you later forfeit the restricted stock, no tax
deduction is allowed with respect to the forfeiture. That is, you will not
receive any credit for taxes paid with respect to such forfeited stock. In all
cases, the amount of ordinary income that you recognize will equal:

. the fair market value of the shares at the time you recognize income, less

. the amount (if any) you pay for the shares.

For example, if you receive 3,200 shares of restricted stock on November 28,
2001, 400 shares would vest in each three-month period.

If you do not make an election under Section 83(b) of the Code, you would
recognize ordinary income for 400 shares on February 27, 2002 and the amount
would be the closing price of our common stock on the following market trading
day. If our stock price is $1.00 on February 28, 2002, you would recognize $400
of ordinary income. If on February 28, 2002, our stock price is $1.25, you
would recognize $500 of ordinary income.

If you do make an election under Section 83(b) of the Code, you would
recognize ordinary income for all 3,200 shares on November 28, 2001, the date
of grant. If our stock price is $1.00 on November 28, 2001, you would recognize
$3,200 of ordinary income. The subsequent vesting of the shares does not
trigger additional recognition of ordinary income.

We will generally be allowed a business expense deduction for the amount of
the taxable income recognized by you in connection with the issuance or vesting
of your restricted stock.

Subsequent Sale of Restricted Stock.

Upon a sale or other taxable disposition of the restricted stock, you will
recognize a taxable capital gain equal to the amount realized upon the sale or
disposition of the shares less their fair market value at the time you
recognized taxable income in connection with those shares. A capital loss will
result to the extent the amount realized upon such sale is less than such fair
market value. The capital gain or capital loss will be long-term if the shares
are held for more than one (1) year prior to the sale.

The capital gain holding period for unvested restricted stock will start
either (i) at the time the restricted stock vests, if no Section 83(b) election
is filed at the time of issuance, or (ii) at the time of issuance, if you file
the Section 83(b) election within 30 days after the date of issuance.

Effect on Incentive Stock Options Not Tendered.

We do not believe that our offer to you will change any of the terms of your
eligible incentive stock options if you do not accept the offer. However, the
Internal Revenue Service may characterize our offer to you as a

"modification" of those incentive stock options, even if you decline the offer.
A successful assertion by the Internal Revenue Service that your incentive
stock options are modified would extend your required holding period with
respect to the shares purchased under those options in order to qualify all of
the gain on a subsequent sale of those shares as long-term capital gain. That
extended holding period for long-term capital gain would require that any
taxable sale or disposition of the shares not take place until the later of (i)
two (2) years from the date of the deemed modification of your incentive stock
options or (ii) one (1) year from the date of the option exercise for those
shares. In addition, such a deemed modification may also cause a portion of
your incentive stock options to be treated as non-qualified stock options upon
exercise.

Withholding Taxes.

. You will be required to open an account with Paine Webber prior to the
vesting of your shares of restricted stock. We will require you to sign
and return the Irrevocable Standing Order to Sell Shares prior to any
vesting of your shares. The Irrevocable Standing Order to Sell Shares
includes provisions authorizing Paine Webber to sell a portion of your
vested shares of restricted stock to pay withholding taxes.

. If you make a Section 83(b) election, you must pay over to us the amount
of the withholding taxes by check at the time of the election. If you do
not pay over the amount of withholding taxes by check, your Section 83(b)
election will not be effective and Paine Webber will rely on your standing
order to sell that number of vested shares that is sufficient to obtain
proceeds to satisfy the withholding tax obligation after each vesting
date, as described below. You will pay Paine Webber's usual trade
commission for this sale.

. If you do not make a Section 83(b) election, on one of three market
trading days following each vesting date, Paine Webber will rely on your
standing order to sell that number of vested shares that is sufficient to
obtain proceeds to satisfy the withholding tax obligation. You will pay
Paine Webber's usual trade commission for this sale.

. The shares will be sold in three blocks on the three consecutive trading
days following the vesting date. You will be assigned to one of three
trading groups that will rotate in selling order for each quarterly
vesting date.

Note: However, if you are an executive officer of InfoSpace subject to the
reporting requirements of Section 16 of the Securities Exchange Act of
1934, as amended, or you are a specifically named "Covered

Person" under the InfoSpace Company Policy Regarding Special Trading
Procedures (Covered Persons will be notified by the Company), your shares
will be sold in one-third increments over the three trading days following
vesting and your selling price will be tracked separately and will be
reported by Paine Webber as your actual sales price for your shares sold.

. You will recognize a short-term capital gain or loss on the shares traded
to pay your withholding taxes and commission based on the difference
between the sales price of your shares sold to cover withholding and the
amount of taxable income recognized on the vesting date (equal to the
closing price of our stock on the trading day following your vesting
date). Any proceeds from your trade not used to pay withholding taxes or
commissions will be deposited into your Paine Webber account.

. The amount of withholding taxes you owe will be based on the closing price
of our stock on the next market trading day following the vesting date. We
will attempt to estimate the correct number of vested shares to be sold to
cover withholding taxes based on the price of our stock on the vesting
date. However, it is possible that the proceeds obtained from the sale
will be either too much or too little to satisfy the withholding tax
obligations. In the event that excess proceeds are received, the excess
will be deposited in your Paine Webber account. In the event that the
proceeds received are insufficient to cover the withholding taxes, then we
reserve the right to either instruct Paine Webber to sell additional
vested shares or deduct the necessary amount from your wages.

WE RECOMMEND THAT YOU CONSULT YOUR OWN TAX ADVISOR WITH RESPECT TO THE
FEDERAL, STATE AND LOCAL TAX CONSEQUENCES OF PARTICIPATION IN THE OFFER.

16. Extension of offer; termination; amendment.

We expressly reserve the right, in our discretion, at any time and from time
to time, and regardless of whether or not any event listed in Section 7 has
occurred or is deemed by us to have occurred, to extend the period of time
during which the offer is open and thereby delay the acceptance for exchange of
any options by giving oral or written notice of such extension to the Eligible
Employees or making a public announcement thereof.

We also expressly reserve the right, in our reasonable judgment, prior to
the expiration date to terminate or amend the offer and to postpone our
acceptance and cancellation of any options tendered for exchange upon the
occurrence of any of the events listed in Section 7, by giving oral or written
notice of such termination or postponement to you or by making a public
announcement. Our reservation of the right to delay our acceptance and
cancellation of options tendered for exchange is limited by Rule 13e-4(f)(5)
promulgated under the Securities Exchange Act of 1934, which requires that we
must pay the consideration offered or return the options tendered promptly
after termination or withdrawal of a tender offer.

Subject to compliance with applicable law, we further reserve the right, in
our discretion, and regardless of whether any event listed in Section 7 has
occurred or is deemed by us to have occurred, to amend the offer in any
respect, including, without limitation, by decreasing or increasing the
consideration offered in the offer to eligible employees or by decreasing or
increasing the number of options being sought in the offer.

Amendments to the offer may be made at any time and from time to time by
public announcement of the amendment. In the case of an extension, the
amendment must be issued no later than 6:00 a.m., Pacific Standard Time, on the
next business day after the last previously scheduled or announced expiration
date. Any public announcement made through the offer will be disseminated
promptly to Eligible Employees in a manner

reasonably designated to inform Eligible Employees of the change. Without
limiting the manner in which we may choose to make a public announcement,
except as required by applicable law, we have no obligation to publish,
advertise or otherwise communicate any such public announcement.

If we materially change the terms of the offer or the information concerning
the offer, or if we waive a material condition of the offer, we will extend the
offer to the extent required by Rules 13e-4(d)(2) and 13e-4(e)(3) under the
Securities Exchange Act of 1934. These rules require that the minimum period
during which an offer must remain open following material changes in the terms
of the offer or information concerning the offer, other than a change in price
or a change in percentage of securities sought, will depend on the facts and
circumstances, including the relative materiality of such terms or information.

If we decide to take any of the following actions, we will publish notice or
otherwise inform you in writing of these actions:

. we increase or decrease the amount of consideration offered for the
options,

. we decrease the number of options eligible to be tendered in the offer, or

If the offer is scheduled to expire at any time earlier than the tenth
(10/th/) business day from, and including, the date that notice of such
increase or decrease is first published, sent or given in the manner specified
in this Section 16, we will extend the offer so that the offer is open at least
ten (10) business days following the publication, sending or giving of notice.

17. Fees and expenses.

We will not pay any fees or commissions to any broker, dealer or other
person for soliciting tenders of options pursuant to this offer.

19. Miscellaneous.

This Offer to Exchange and our SEC reports referred to above include
"forward-looking statements." When used in this Offer to Exchange, the words
"anticipate," "believe," "estimate," "expect," "intend" and "plan" as they
relate to InfoSpace or our management are intended to identify these
forward-looking statements. All statements by us regarding our expected future
financial position and operating results, our business strategy, our financing
plans and expected capital requirements, forecasted trends relating to our
services or the markets in which we operate and similar matters are
forward-looking statements. The documents we filed with the SEC, including our
annual report for the year ended December 31, 2000, on Form 10-K filed on April
2, 2001, as amended, discuss some of the risks that could cause our actual
results to differ from those contained or implied in the forward-looking
statements. These risks include, but are not limited to:

. We have a history of losses and expect to continue to incur significant
operating losses, and we may never be profitable.

. We have relatively limited operating history, which makes it difficult to
evaluate our future prospects.

. Our financial results are likely to continue to fluctuate, which could
cause our stock price to be volatile or decline.

. Our stock price has been and is likely to continue to be highly volatile.

. If we are unable to diversify our revenue base, a significant portion of
our revenues will continue to be derived from wireline consumer services,
which could weaken our financial position.

. Our financial and operating results will suffer if we are unsuccessful at
integrating acquired businesses.

. Our future earnings could be negatively affected by significant charges
resulting from the impairment in the value of acquired assets.

. Our revenues are attributable to a small number of customers, the loss of
any one of which could harm our financial results.

. We depend on third parties for content, and the loss of access to this
content could cause us to reduce our product offerings to customers.

. Unless we are able to hire, retain and motivate highly qualified
employees, we will be unable to execute our business strategy.

. Our historical and future expansion in personnel and facilities will
continue to significantly strain our management, operational and financial
resources.

. Our expansion into international markets may not be successful and may
expose us to risks that could harm our business.

. We have implemented anti-takeover provisions that could make it more
difficult to acquire us.

. Our systems could fail or become unavailable, which would harm our
reputation, result in a loss of current and potential customers and could
cause us to breach existing agreements.

. We rely heavily on our proprietary technology, but we may be unable to
adequately protect or enforce our intellectual property rights thus
weakening our competitive position and negatively impacting our financial
results.

. Intense competition in the wireline, wireless and broadband markets could
prevent us from entering those markets or cause us to lose market share.

. We rely on the Internet infrastructure, and its continued commercial
viability, over which we have no control and the failure of which could
substantially undermine our business strategy.
