delivered by AdStar and is the legal, valid and binding obligation of AdStar
enforceable in accordance with its terms, and each of the Transaction Documents

subject to bankruptcy, insolvency, reorganization, moratorium or other similar
laws affecting the enforcement thereof or by general equitable principles.

            (b) Neither the execution and delivery of this Agreement or any of
the Transaction Documents or the consummation of any of the transactions
contemplated hereby or thereby nor compliance with or fulfillment of the terms,
conditions and provisions hereof or thereof will:

            (i) conflict with, result in a breach or violation of the terms,
      conditions or provisions of, or constitute a default, an event of default
      or an event creating rights of acceleration, termination or cancellation
      or a loss of rights under, or result in the creation or imposition of any
      Lien upon any of the assets or properties of AdStar, under (A) the
      Certificate of Incorporation or the By-laws or (B) any note, instrument,

            7.4. Authorized Capital Stock. (a) As of the Closing, the authorized
capital stock of AdStar consists of (i) 20,000,000 shares of Common Stock, the
number of issued and outstanding shares of which is as set forth in Schedule 7.4
and (ii) 5,000,000 shares of preferred stock, $0.0001 par value, of which
1,443,457 shares have been designated as Series A Preferred Shares and the

AdStar has reserved for issuance (x) sufficient shares of Common Stock for
issuance upon conversion of all outstanding Series A Preferred Shares, (y)
3,152,530 shares of Common Stock upon exercise of outstanding options and

options, warrants, conversion rights, agreements or other rights to purchase any
of the authorized but unissued capital stock of AdStar or any securities

                                   ARTICLE IX

                                  MISCELLANEOUS

            9.1. Survival of Representations and Warranties. All representations
and warranties contained herein or made in writing by any Party in connection
herewith will survive the execution and delivery of this Agreement and the
consummation of the transactions contemplated hereby, regardless of any
investigation made by or on behalf of the Investor.

            9.2. Amendments and Waivers. Except as otherwise expressly provided
herein, the provisions of this Agreement may be amended, modified or waived only
with the written consent of AdStar and the Investor. No course of dealing
between AdStar and the holder of any Series A Preferred Shares or any delay in
exercising any rights hereunder or under the Transaction Documents or the
Certificate of Designation will operate as a waiver of any rights of any such
holders.

            9.3. Successors and Assigns. Except as otherwise expressly provided
herein, all covenants and agreements contained in this Agreement by or on behalf
of any of the Parties will bind and inure to the benefit of the respective
successors and permitted assigns of the Parties, whether so expressed or not. It
is expressly understood that, in the event of a sale by Investor of a portion of
its Series A Preferred Stock to Knight Ridder, Knight Ridder shall qualify as a
permitted assign under this Section 9.3, and after any such sale Knight Ridder
shall be entitled to all rights and remedies (and shall be bound by any
obligations) of a holder of Series A Preferred Stock hereunder to the same
extent as the Investor.

            9.4. Remedies. The Investor shall be entitled to enforce any rights
it has under this Agreement or the Transaction Documents specifically (without
posting a bond or other security), to recover damages by reason of any breach of
any provision of this Agreement and to exercise all other rights granted by law.

            9.5. Indemnification. In consideration of the Investor's execution
and delivery of this Agreement and acquisition of the Series A Preferred Shares
and in addition to all of AdStar's other obligations under this Agreement,
AdStar shall defend, protect, indemnify and hold harmless the Investor and each
other holder of Series A Preferred Shares and Conversion Common Shares and all
of their partners, officers, directors, employees and agents (including those
retained in connection with the transactions contemplated by this Agreement)
(collectively, the "Indemnitees") from and against any and all actions, causes
of action, suits, claims, losses, costs, penalties, fees, liabilities and
damages, and expenses (irrespective of whether any such Indemnitee is a party to
the action for which indemnification hereunder is sought), and including
reasonable attorneys' fees and disbursements (the "Indemnified Liabilities"),
incurred by the Indemnitees as a result of, or arising out of, or relating to
(a) any breach by AdStar of any of the representations, warranties or covenants
contained in this Agreement or any of the Transaction Documents or (b) any
third-party claims incurred solely as a result of the fact that such Person is a
stockholder of AdStar (or a partner, officer, director, employee or agent of
such Person). To the extent that the foregoing undertaking by AdStar may be
unenforceable for any reason, AdStar shall make the maximum contribution to the
payment and satisfaction of each of the Indemnified Liabilities that is
permissible under applicable law.

            9.6. Severability. Wherever possible, each provision of this
Agreement will be interpreted in such manner as to be effective and valid under
applicable law and in such a way as to, as closely as possible, achieve the
intended economic effect of such provision and this Agreement as a whole, but if
any provision contained herein is, for any reason, held to be invalid, illegal
or unenforceable in any respect, such provision shall be ineffective to the
extent, but only to the extent, of such invalidity, illegality or
unenforceability without invalidating the remainder of such provision or any
other provisions hereof, unless such a construction would be unreasonable.

            9.7. Notices. All notices or other communications required or
permitted hereunder shall be in writing and shall be deemed given or delivered

of transmission is received, (c) if sent by registered or certified mail,

Illinois or any other jurisdiction) that would cause the application of the laws
of any jurisdiction other than the State of Illinois. In furtherance of the
foregoing, the internal law of the State of Illinois shall control the
interpretation and construction of this Agreement (and all Schedules and
Exhibits hereto), even though under that jurisdiction's choice of law or
conflict of law analysis, the substantive law of some other jurisdiction would
ordinarily apply.

            9.9. Submission to Jurisdiction; Waiver of Jury Trial. (a) Each of
the Parties hereby irrevocably submits in any suit, action or proceeding arising
out of or related to this Agreement or any of the Transaction Documents, or any
of the transactions contemplated hereby or thereby, to the exclusive
jurisdiction of the United States District Court for the Northern District of
Illinois and the Circuit Court of Cook County, Illinois and, to the extent
permissible by law, waives any and all claims and objections that any such court
is an inconvenient forum.

            (b) EACH OF THE PARTIES HEREBY EXPRESSLY WAIVES ANY RIGHT TO TRIAL
BY JURY IN ANY DISPUTE, WHETHER SOUNDING IN CONTRACT, TORT OR OTHERWISE, BETWEEN
OR AMONG ANY OF THE PARTIES ARISING OUT OF OR RELATED TO THE TRANSACTIONS
CONTEMPLATED BY THIS AGREEMENT OR ANY OF THE TRANSACTION DOCUMENTS, OR ANY OTHER
INSTRUMENT OR DOCUMENT EXECUTED OR DELIVERED IN CONNECTION HEREWITH OR
THEREWITH. ANY PARTY MAY FILE AN ORIGINAL COUNTERPART OR A COPY OF THIS
AGREEMENT WITH ANY COURT AS WRITTEN EVIDENCE OF THE CONSENT OF THE PARTIES TO
THE WAIVER OF THEIR RIGHT TO TRIAL BY JURY.

            9.10. Attorneys' Fees. In the event of any action or suit based upon
or arising out of any actual or alleged breach by any Party of any
representation, warranty or agreement in this Agreement, the prevailing party
shall be entitled to recover its reasonable attorneys' fees and expenses of such
action or suit from the losing party, in addition to any other relief ordered by
the court.

            9.11. Execution in Counterparts. This Agreement may be executed in
any number of counterparts (including via facsimile), each of which will be
considered an original instrument, but all of which together will be considered
one and the same agreement, and will become binding when one or more
counterparts have been signed by and delivered to each of the Parties.

            9.12. Delivery by Facsimile. This Agreement, to the extent signed
and delivered by means of a facsimile machine, shall be treated in all manner
and respects as an original agreement or instrument and shall be considered to
have the same binding legal effect as if it were the original signed version
thereof delivered in person. At the request of any Party, each other Party shall
reexecute original forms thereof and deliver them to all other Parties. No Party
shall raise the use of a facsimile machine to deliver a signature or the fact
that any signature or agreement or instrument was transmitted or communicated
through the use of a facsimile machine as a defense to the formation or
enforceability of a contract and each such Party forever waives any such
defense.

            9.13. Entire Agreement. This Agreement and the Exhibits and

                    ARTICLE II - DEVELOPMENT AND DEPLOYMENT

            SECTION 2.1. Purpose. The Parties hereby acknowledge and agree that
the CareerBuilder Service is being developed for the sole and exclusive benefit
of Tribune and its Affiliates and the CareerBuilder Network.

            SECTION 2.2. Obligations of AdStar. (a) AdStar shall be responsible
for supplying the resources necessary to (i) reconfigure and customize the
AdStar Service, (ii) install data and other components into the AdStar database,
and (iii) develop the Modules, all in the manner, time and date as specified on
Exhibit A hereto and as necessary to support the requirements of the
CareerBuilder Service and (iv) build a user interface for use by agencies and
advertisers with the "look and feel", branding and links requested by Tribune in
its sole discretion.

            (b) In addition to any other personnel needed to meet the objectives
of this Agreement, AdStar will specifically devote the equivalent of two
full-time employees (the "Developers"), at no additional charge to Tribune, to
the development and deployment of the CareerBuilder Service and to providing
Upgrades and Enhancements. The Developers shall for the term of this Agreement
be responsible for performing Upgrades and Enhancements.

            SECTION 2.3. Progress Reports. Beginning on the Closing Date and
ending on the completion of all of the development contemplated on Exhibit A,
AdStar shall submit to Tribune on a weekly basis, or at such other times as
Tribune may reasonably request, written progress reports relating to the
development of the CareerBuilder Service. Each progress report shall include,
without limitation, project plans, technical designs, Q&A reports, discussion of
progress to date, problems encountered, proposed solutions to such problems and
any other items reasonably requested by Tribune.

            SECTION 2.4. Acceptance Tests. (a) Upon delivery of the completed
CareerBuilder Service pursuant to the schedule set forth in Exhibit A, as
amended from time to time, Tribune, AdStar, any Tribune Newspaper, any Knight
Ridder Newspaper and/or their representatives shall conduct the Acceptance Tests
as specified in Exhibit A, as the same will be developed and updated by Tribune
for the completed CareerBuilder Service.

            (b) If in the course of conducting Acceptance Tests, Tribune or its
representatives determine that the CareerBuilder Service (including the testing
of any Upgrade or Enhancement) does not materially perform in accordance with
the applicable Acceptance Tests, Tribune shall promptly notify AdStar and AdStar
shall, within thirty (30) days, or such other time period as may be requested by
AdStar and approved by Tribune, at AdStar's sole cost and expense, modify or
improve the CareerBuilder Service so that the same shall perform in accordance
with the Acceptance Tests. Upon redelivery of the CareerBuilder Service, Tribune
and AdStar or their representatives shall conduct, as applicable, additional
Acceptance Tests as specified in Exhibit A or such other documents as agreed by
the Parties.

            (c) The material failure of the CareerBuilder Service to meet the
applicable Acceptance Tests after the second set of Acceptance Tests, which
failure is not due to any action

                                      -5-
<PAGE>

or inaction on the part of Tribune (of which Tribune has received prior written
notice from AdStar), shall constitute a material breach of this Agreement by
AdStar.

            SECTION 2.5. Milestones; Delay. (a) AdStar shall notify Tribune on a
continuing basis of any event or occurrence that could cause a material delay in
meeting any milestone set forth in Exhibit A or otherwise delay the development
of the CareerBuilder Service. Any material delay which is caused by AdStar,
other than a delay resulting from a Force Majeure Event or due to any action or
inaction on the part of Tribune or CareerBuilder (of which Tribune has received
notice from AdStar) shall be deemed to be a material breach of this Agreement.
If, in the event of such delay, Tribune, in its sole discretion, elects not to
exercise its rights under Article X or otherwise pursuant to this Agreement,
Tribune may, by written notice, designate a new date for the completion of the
delayed CareerBuilder Service.

            (b) If a new completion date is designated, AdStar shall pay

any Change Order until such Change Order is executed by both Parties. Each
Change Order executed by Tribune and AdStar shall be incorporated into and
constitute an amendment to this Agreement. The terms of any Change Order shall
control over any inconsistent provisions set forth in this Agreement or any
attachment hereto.

such Party's performance under this Agreement; (ii) interacting with the other
Party's Project Manager; and (iii) supervising the performance of such Party's
obligations under this Agreement. Project Managers of each Party shall meet as
needed, but no less often than monthly to review progress and to resolve issues

            (b) Tribune may, if good cause exists therefor, withdraw its
approval of AdStar's Project Manager. If AdStar's Project Manager is unable to

unreasonably withheld or delayed.

            SECTION 2.8. Management by Tribune. Notwithstanding anything to the
contrary herein, Tribune shall have the right to manage the development
specified herein provided by AdStar if, in Tribune's reasonable judgment, it

that Tribune exercises its rights under this Section 2.8 (i) AdStar will
continue to use best efforts to meet the objectives of this Agreement, (ii)
AdStar will not be subject to any liquidated damages under Section 2.5 accruing
after the date on which Tribune begins such management and (iii) Tribune will be

Tribune and its Affiliates an exclusive (even as against AdStar), perpetual,
irrevocable, sublicensable (but only to Affiliates of Tribune or members of the
CareerBuilder Network), worldwide, transferable (but only to Affiliates of
Tribune or members of the CareerBuilder Network) right and license to use,
reproduce, display, modify and transmit the Modules and Enhancements or other
modifications thereto. The parties hereby acknowledge and agree that the
computer code written for the Modules, as defined in Exhibit B, may not be used
by AdStar to create software for any third party. The definition of the Modules

by mutual agreement between the parties.

(even as against AdStar), sublicensable (but only to Affiliates of Tribune or
members of the CareerBuilder Network), worldwide, transferable (but only to
Affiliates of Tribune or members of the CareerBuilder Network) right and license
for the Term to use, reproduce, display, modify and transmit the CareerBuilder
Service other than the Modules and Enhancements or other modifications thereto
(the "License").

            SECTION 3.2. Further Licenses. Upon the prior consent of Tribune,

create Enhancements to the CareerBuilder Service, and AdStar agrees to use its
best efforts in performing the services to develop such Enhancements. Tribune
may also request that AdStar create improvements or modifications to the
CareerBuilder Service to be used in Other Classified Verticals and such
improvements or modifications will be considered Enhancements for the purposes
of this Agreement. The use of the Developers to create Enhancements shall not be
chargeable to Tribune. Any work related to Enhancements that requires employees
or consultants in addition to the Developers will be chargeable to Tribune on a
time and materials basis without mark-up; provided, however, that if Tribune's
concept for an Enhancement is under active development by AdStar with a
projected deployment date ("Deployment Date"), Tribune shall have the option to
(i) wait until the Deployment Date and receive the new functionality as an
Upgrade, or (ii) request that the new functionality be developed on an
accelerated basis with Tribune paying any applicable fees in accordance with the
Agreement. If Tribune opts to proceed under clause (ii), the Parties shall
mutually agree whether such new functionality will be considered an Enhancement
(and subject to Article VIII) or, if not, whether any period of exclusivity will
apply and whether and on what basis AdStar will repay to Tribune any fees paid
for development of the new functionality or reimburse Tribune for the use of the
Developers.

            (b) Tribune shall request a Statement of Work from AdStar for each
Enhancement to the CareerBuilder Service it desires. AdStar shall deliver the

Enhancement and the related services to be provided; (ii) the scope of the
services; (iii) any specific Confidential Information (as defined below) of a
Party to be incorporated into or form the basis of the Enhancement (iv) the

Parties as stated herein.

            SECTION 5.2. Development Schedule. Following receipt of a Statement
of Work, AdStar and Tribune shall mutually agree to a schedule for the
development of the Enhancement and an estimate of the hours required to create
such Enhancement (the "Development Schedule"). If Tribune approves the
Development Schedule, AdStar shall use its best efforts to create the
Enhancement pursuant to the Development Schedule. AdStar shall provide reports
to Tribune on the progress of the Enhancements as specified in Section 2.3.

            SECTION 5.3. Acceptance of Enhancements. Acceptance testing of
Enhancements shall be conducted as specified in Article II or as otherwise

            SECTION 5.4. Tribune's Cooperation. Tribune acknowledges that the
successful and timely rendering of the services and provision of the
Enhancements requires the good faith cooperation of Tribune. Tribune shall

required information concerning the proposed services and intended Enhancements
as may be reasonably required by AdStar; and (b) making reasonably available to
AdStar such personnel of Tribune as are familiar with the anticipated
requirements of the Enhancements; Tribune's Project Manager shall be the only
person authorized to act for Tribune with respect to the matters related to the
applicable Statement of Work.

            SECTION 5.5. Ownership of Enhancements. Except for Joint
Developments under Section 6.4, upon completion of the services under the
Statement of Work, all Enhancements developed by AdStar hereunder, including,
without limitation, all modifications and derivative works of the CareerBuilder
Service, and the CareerBuilder Service so enhanced, are and shall become and
remain, as between AdStar and Tribune, the sole and exclusive property of
AdStar, subject to any Third Party Technology included therein and the exclusive
rights and covenants granted herein. AdStar hereby grants to Tribune an
exclusive license to use the Enhancement during the Term, on the same
conditions, and to the same extent, as the License of the CareerBuilder Service
granted to Tribune under Section 3.1 of this Agreement.

                             ARTICLE VI - OWNERSHIP

            SECTION 6.1. Ownership Rights. All intellectual property rights in
and to the CareerBuilder Service created prior to or during the Term, including
all Enhancements (except as limited by Section 6.4), are solely and exclusively
owned by AdStar, subject to the exclusive rights and covenants granted herein.
All ownership and intellectual property rights in and to any and all data and
information processed through the CareerBuilder Service are and shall remain the
sole and exclusive property of Tribune and AdStar shall provide such data to
Tribune as soon as practicable if and when requested.

            SECTION 6.2. Maintenance of Intellectual Property Rights. AdStar
shall take all action necessary to maintain and protect the Intellectual
Property Rights subsisting in the CareerBuilder Service. Tribune may request
that AdStar take any specific action, and AdStar shall not unreasonably deny any

Tribune shall reasonably cooperate with AdStar in the maintenance of the
applications and registrations relating to the Intellectual Property Rights
subsisting in the CareerBuilder Service, including executing such instruments as
AdStar may from time to time reasonably request.

            SECTION 6.3. Goodwill. Any and all goodwill arising from Tribune's
use of any trademarks owned by AdStar included within the CareerBuilder Service
shall inure solely to the benefit of AdStar. Any and all goodwill arising from
AdStar's use of any trademarks owned by Tribune included within the
CareerBuilder Service shall inure solely to the benefit of Tribune.

            SECTION 6.4. Joint Developments. During the term of this Agreement,
any idea, invention, design, process, improvement, discovery, know-how, computer

and all Intellectual Property

                                      -9-
<PAGE>

Rights therein, which the Parties invent, create or develop jointly, shall be
jointly owned without a right of accounting ("Joint Developments"). AdStar
agrees, however, that its interest in Joint Developments shall be subject to the
terms of this Agreement.

            SECTION 6.5. Use of Third Party Technology by AdStar. AdStar has not
and shall not incorporate any material Third Party Technology in the
CareerBuilder Services unless: (i) such technology and their owners (including
the owners of any patents, copyrights, trade secrets, trademarks or other
intellectual property rights embedded therein) are identified in writing to
Tribune, and (ii) AdStar either: (x) has sufficient authority to grant to
Tribune the rights and licenses necessary to exploit the CareerBuilder Service
as contemplated herein (y) the third party owner has granted directly to Tribune
rights and licenses in such materials necessary to exploit the CareerBuilder
Service as contemplated herein pursuant to a separate written agreement.
Schedule 6 contains a complete and accurate list of all Third Party Technology
used or contemplated to be used in the CareerBuilder Service and except as
specified in Schedule 6, AdStar has the right to assign all Third Party
Technology licenses incorporated in the CareerBuilder Service to Tribune in the
event of a release of the Deposit Materials pursuant to Article X. AdStar also
agrees that it will use its best efforts to assign any Third Party Technology
licenses to Tribune in the event of a release of the Deposit Materials as
specified in Article X and will use it best efforts to secure such rights in all
future Third Party Technology licenses. AdStar shall have sole responsibility
for payment of all royalties and other charges with respect to Third Party
Technology employed by AdStar and included in the CareerBuilder Service or the
Modules, including as they may accrue with respect to subsequent exercise by
Tribune, its Affiliates, customers, and successors and assigns. With respect to
material Third Party Technology that is identified in writing to Tribune, AdStar
shall, prior to incorporating the same in the CareerBuilder Services, either
provide to Tribune a copy of any agreements or other instruments from which
AdStar derives its authority to grant Tribune the rights contemplated herein, or
shall allow Tribune's counsel to review such agreements or other instruments on
a confidential basis for the purpose of advising Tribune with respect to
AdStar's authority to grant Tribune such rights and licenses. Failure to provide
such agreements or instruments to Tribune or Tribune's counsel shall be deemed a
material breach of this Agreement; provided, however, that AdStar shall have ten
(10) calendar days to provide such agreements upon notice from Tribune. If
Tribune is not satisfied that AdStar has sufficient rights with respect to any
Third Party Technology, or if AdStar fails to assume and discharge its
responsibility for related royalties and other charges, Tribune may suspend
further action or payment with respect to this Agreement. Nothing contained in
this Section 6.5 shall apply to Third Party Technology incorporated into the
CareerBuilder Services at the request of Tribune, or to restrict or preclude
Tribune from dealing directly with any third party with respect to such Third
Party Technology.

been received in exchange for the covenants set for in Schedule 8.

            SECTION 8.2. Integration Fees. Tribune will pay AdStar a $25,000
integration fee for each additional Tribune newspaper that becomes an AdStar
customer (each, an "Additional Newspaper") after the Closing Date; it being
understood that no Additional Newspaper will be obligated to become an AdStar
customer and that, if such Additional Newspaper desires to become an AdStar
customer, the Additional Newspaper will either execute a License Agreement with
AdStar substantially in the form of Exhibit G to the Investment Agreement or

AdStar pursuant to Section 11.1 may be entered into without the consent of
Tribune, if such settlement, payment judgment or other voluntary final
disposition would subject Tribune to an injunction, require that Tribune make a
monetary payment, or otherwise materially adversely affect Tribune's rights
under this Agreement.

                         ARTICLE XII - INDEMNIFICATION

            SECTION 12.1. Indemnification by Tribune. Except for matters
indemnified by AdStar under Section 12.2, Tribune agrees to indemnify, defend,
and hold AdStar and its directors, officers, employees, representatives and
agents harmless from and against any and all claims (including those for
personal injury or death), losses, damages, obligations, liabilities and costs
(including reasonable out-of-pocket attorneys' and other professional fees and
other costs of litigation) (collectively, "Liabilities") arising out of or
attributable to: (a) the gross negligence or willful misconduct of Tribune in
connection with this Agreement; (b) any material breach of any warranty or the
inaccuracy of any representation of Tribune contained or referred to in this
Agreement; or (c) any material breach of any covenant or obligation of Tribune
under this Agreement.

            SECTION 12.2. Indemnification by AdStar. Except for matters
indemnified under Section 12.1, AdStar agrees to indemnify, defend, and hold
Tribune, it Affiliates and their directors, officers, employees, representatives
and agents harmless from and against:

            (a) any and all Liabilities, arising out of or attributable to: (i)
the gross negligence or willful misconduct of AdStar in connection with this
Agreement; (ii) any material breach of any warranty or the inaccuracy of any
representation of AdStar contained or referred to

                                      -15-
<PAGE>

in this Agreement; or (iii) any material breach of any covenant or obligation of
AdStar under this Agreement; and

            (b) Any and all Liabilities arising out of or attributable to the
CareerBuilder Service or any component thereof infringing, misappropriating or
violating any Intellectual Property Rights of any third Party and/or based upon
any claim, which, if true, would constitute a breach of any express warranty
made by AdStar hereunder.

            SECTION 12.3. Indemnification Procedures. In the event that any
Party intends to claim indemnification pursuant to Section 12.1 or Section 12.2
(an "Indemnitee"), it shall promptly notify the indemnifying Party (the
"Indemnitor") in writing of such alleged liability; provided, however, that the
failure to promptly notify the Indemnitor shall not relieve the Indemnitor of
any obligation under this Agreement except to the extent such failure to provide
prompt notice adversely impairs the Indemnitor's ability to defend against the
claim, suit or proceeding. The Indemnitor shall have the sole right to control
the defense and settlement of the liability, provided that: (a) the Indemnitor
may not consent to imposition of any obligation or restriction on the Indemnitee
in any settlement unless mutually agreed in writing among the Parties; (b)
Indemnitor shall keep Indemnitee fully informed and permit the Indemnitee to
participate (at Indemnitee's expense) as the Indemnitee may reasonably request;
and (c) Indemnitee may, without affecting its right to indemnity hereunder,
defend and settle any such claim, suit or proceeding if Indemnitor declines to
defend against such claim, suit or proceeding or files for bankruptcy. The
Indemnitee shall cooperate with the Indemnitor and its legal representatives in
the investigation of liability covered by Section 12.1 or Section 12.2. The
Indemnitee shall not, except at its own cost, voluntarily make any payment or
incur any expense with respect to any claim or suit without the prior written
consent of Indemnitor, which Indemnitor shall not be required to give, provided
that the Indemnitee may, without affecting its right to indemnity hereunder,
defend and settle any such claim, suit or proceeding if the Indemnitor declines
to take responsibility or files for bankruptcy.

                      ARTICLE XIII - TERM AND TERMINATION

            SECTION 13.1. Term. Except for the license grant in Section 3.1(a)
which shall be perpetual and except as set forth in Section 15.16, the term of
this Agreement shall commence on the Closing Date and continue in full force and
effect for as long as the Service Agreement between AdStar and CareerBuilder
dated the date hereof, as the same may be renewed, amended or extended, is in
effect ( the "Term").

            SECTION 13.2. Termination by Either Party With Notice. Either Party
shall have the right to terminate this Agreement by providing written notice to
the other Party for any breach or alleged breach by the other Party of any
material covenant, term, or condition of this Agreement. Such notice shall
adequately describe the nature of the breach, and the breaching Party shall have
thirty (30) calendar days from receipt of such notice to attempt to cure the
breach. If the breach is not cured within such thirty (30) calendar day period,
the non-breaching Party may terminate this Agreement in its entirety by
providing the breaching Party with written notice of termination. At the request
of the breaching Party, the non-breaching Party may consent to extend the cure
period for up to an additional sixty (60) calendar days, which consent

                                      -16-
<PAGE>

shall not be withheld or delayed unreasonably if the breaching Party has
commenced commercially reasonable, good faith cure efforts during such period
and has continued to pursue such cure.

            SECTION 13.3. Termination By Either Party Without Notice. Either
Party may terminate this Agreement in its entirety immediately upon the
occurrence of any of the following events with respect to the other Party: (a) a
receiver is appointed for such Party or its material assets; (b) such Party
becomes insolvent, generally unable to pay its debts as they become due, or
makes an assignment for the benefit of its creditors or seeks relief under any
bankruptcy, insolvency or debtor's relief law; or (c) if proceedings are
commenced against such Party under any bankruptcy, insolvency or debtor's relief
law, and such proceedings have not been vacated or set aside within sixty (60)
calendar days from the date of commencement thereof.

            SECTION 13.4. Rights of Parties Upon Termination. (a) In any case of
termination where Tribune fails to make a payment required hereunder and such
nonpayment remains uncured for thirty (30) days after demand from AdStar for
payment, Tribune shall have no further rights to License the CareerBuilder
Service under Section 3.1, and shall, as directed by AdStar return to AdStar
immediately upon such termination all Confidential Information of AdStar that is
not necessary for the maintenance of the CareerBuilder Service.

            (b) In any case of termination where AdStar is the breaching Party
under Section 13.2 or Section 13.3 (subject to any applicable provisions of the
Escrow Agreement), in addition to any other rights and remedies of Tribune under
this Agreement, Tribune shall be entitled to continuous exercise of its License
under Section 3.1. If such termination constitutes a Release Condition under the
Escrow Agreement, Tribune shall receive access to the Deposit Materials pursuant
to the terms and conditions of such Escrow Agreement. In addition to the
foregoing, AdStar shall, as directed by Tribune, either: (i) return to Tribune
all of Tribune's Confidential Information in its possession, custody or control;
or (ii) provide a written certification from an officer of AdStar as to the
destruction of the foregoing.

                         ARTICLE XIV - CONFIDENTIALITY

            SECTION 14.1. Confidential Information. In connection with this
Agreement, each of AdStar and Tribune (in such capacity, the "Recipient") has
received, developed or been given access to, and shall in the future receive,
develop or be given access to, certain information and materials deemed
confidential by and proprietary to the other Party (in such capacity, the
"Disclosing Party"). Subject to Section 14.2, regardless of whether such
information and materials are furnished in whole or part, in writing or orally,
or in any physical format including without limitation, written documents and
computer-related media, and whether or not such information is made available to
a Party under this Agreement, such information and materials may include,
without limitation, (a) the Disclosing Party's services (both existing and under
development during the Term), including, as to AdStar, the CareerBuilder
Service, Source Code, Object Code, Enhancements, Intellectual Property Rights
and Know-How; (b) information, data, materials, subject matter, algorithms,
work-flows, models, formulae, structures, schematics, designs, drawings,
specifications, flow charts, diagrams and methods and processes of, contained in
or embodied by any of the Disclosing Party's CareerBuilder Services (both
existing and under

                                      -17-
<PAGE>

development during the Term) and related documentation, including, as to AdStar,
such as may related to the CareerBuilder Service, Source Code, Object Code,
Enhancements, Intellectual Property Rights and Know-How; and (c) information,
data, materials, subject matter, methods and processes, concerning the current
or prospective businesses, customers, potential customers, employees, operating
methods, sources of supply, potential sources of supply, distribution methods,
sales, sales plans, sales methods, profits, markets, financing or plans for
future development (collectively, the "Confidential Information").

            SECTION 14.2. Exclusions. Notwithstanding anything to the contrary
contained in Section 14.1, Confidential Information shall not include any
information or materials which: (a) prior to disclosure, are or were known or
generally available to the public other than by means of a breach of this
Agreement; (b) after disclosure, become known to the public through no act or
omission of the Recipient or any other person with an obligation of
confidentiality to the Disclosing Party; (c) are independently developed by or
for the Recipient, as evidenced by written records of the Recipient; or (d) are
required to be disclosed pursuant to an application, law, rule, regulation,
government requirement or court order, or the rules of any stock exchange;
provided, however, that the Recipient shall advise the Disclosing Party of such
required disclosure promptly upon learning thereof in order to afford the
Disclosing Party a reasonable opportunity to contest, limit and assist the
Recipient in responding to such disclosure.

            SECTION 14.3. Protection of Confidential Information. The Recipient
shall hold in the strictest confidence all Confidential Information provided to
it and shall not make any disclosure of the Disclosing Party's Confidential
Information to any person other than its Authorized Representatives during the
Term of this Agreement and for a period of three (3) years thereafter; provided,
however, that upon a Release Condition that is not cured by AdStar, Tribune
shall no longer be subject to the restrictions of Article XIV to the extent
necessary to operate the CareerBuilder Services. The Recipient shall handle the
Disclosing Party's Confidential Information with the same degree of care and
through procedures no less stringent than those taken to protect its own
Confidential Information. Notwithstanding the foregoing, the Recipient may
disclose such Confidential Information to those directors, officers, employees,
agents, advisors and sublicensee of the Recipient who have a need to know such
information in connection with the use by Recipient of the CareerBuilder Service
or in connection with its performance under this Agreement ("Authorized
Representatives"). The Recipient shall be responsible for any and all breaches
of the provisions of this Section 14.2 by its Authorized Representatives.

            SECTION 14.4. Restricted Use of Confidential Information. The
Recipient and its Authorized Representatives shall use the Disclosing Party's
Confidential Information solely in connection with performance under this
Agreement or any sublicense, and for no other purpose. All Confidential
Information shall remain the sole and exclusive property of the Disclosing Party
and, other than the License expressly granted to the CareerBuilder Service, no
disclosure or permitted use of the Confidential Information under this Agreement
shall be construed as the grant of any right, title or interest, by license or
otherwise, in or to the Confidential Information related to the CareerBuilder
Service. The Disclosing Party shall use commercially reasonable efforts to
identify all embodiments of the Confidential Information (in whatever medium)
with the legend "Confidential;" provided, however, that any material

                                      -18-
<PAGE>

reasonably believed to be confidential by the Receiving Party and not stamped
"Confidential" shall also be treated as Confidential Information.

            SECTION 14.5. Obligation to Inform. Upon learning of any
unauthorized disclosure or use of a Disclosing Party's Confidential Information,
the Party learning of such disclosure promptly shall provide the Disclosing
Party with written notice thereof.

                        ARTICLE XV - GENERAL PROVISIONS

            SECTION 15.1. Governing Law; Submission to Jurisdiction. This
Agreement and any disputes arising hereunder or related hereto shall be governed
by and construed in accordance with the internal laws of the State of Illinois,
without regard to principles of conflicts of laws. By the execution and delivery
of this Agreement, the Parties submit to the venue and personal jurisdiction of
any federal or state court in the State of Illinois in any suit or proceeding
arising out of or relating to this Agreement.

            SECTION 15.2. Public Announcement. The Parties shall mutually agree
upon and issue a press release within five (5) calendar days of the Closing
Date. Neither Party shall issue any press release, publicity statement or other
public notice or announcement relating to this Agreement without the prior
consent of the other Party in each instance. Nothing in this Section 15.2 shall
be construed as prohibiting AdStar's use of the name and identity of Tribune in
sales or marketing or similar materials distributed to prospective customers or
investors of AdStar.

            SECTION 15.3. Non-Solicitation/Non-Hiring. The Parties recognize
that their respective employees, and such employees' loyalty and services,
constitute valuable assets of the other. Accordingly, neither Party shall,
during the Term and for a period of one (1) year thereafter, directly or
indirectly solicit, employ, offer to employ, nor engage as a consultant, any
employee or independent consultant of the other Party with whom such Party had
contact pursuant to this Agreement, without the express consent of the other
Party in each instance; provided, however, that in the event the Deposit
Materials are released to Tribune pursuant to the Escrow Agreement, this Section
15.3 shall no longer apply to either Party.

            SECTION 15.4. Disputes. In the event of any disagreement,
controversy or dispute regarding performance under or interpretation of this
Agreement, the Parties agree to attempt to reach a negotiated resolution among
themselves. If after twenty (20) calendar days Tribune and AdStar have not
agreed to resolve the dispute, AdStar will have the right to present the dispute
and proposed resolution to both (i) the Chief Technology Officer (or an officer
with similar responsibilities) of Tribune Company and (ii) President of Tribune
Publishing and Tribune will have the right to present the dispute and proposed
resolution to Eli Rousso. If such disagreement, controversy or dispute can not
be resolved within ten (10) calendar days of such escalation, the Parties may
pursue their rights under this Agreement or otherwise. The periods specified in
this Section 15.4 may be increased on a one-to-one basis for each day the
appropriate Tribune personnel are not available to engage in dispute resolution.
If no resolution of a dispute is achieved pursuant to this Section 15.4, AdStar
will fully cooperate with Tribune if such failure to resolve a dispute entitles
Tribune to a release of the Deposit Materials.

                                      -19-
<PAGE>

            SECTION 15.5. Assignment. Subject to the terms of this Agreement,
neither Party may assign or transfer this Agreement without the prior written
consent of the other Party, except that Tribune (and not AdStar) may transfer or
assign this Agreement without such consent: (a) in connection with the sale of
all or significant portion of its assets; or (b) to the surviving entity in any
merger or consolidation.

            SECTION 15.6. Successors. This Agreement shall be binding upon and
inure solely to the benefit of each Party and their successors and assigns, and
nothing in this Agreement, express or implied, is intended to or shall confer
upon any other person any right, benefit or remedy of any nature whatsoever
under or by reason of this Agreement.

            SECTION 15.7. Independent Contractors. No agency, partnership or
joint venture is established by this Agreement. Neither Party shall enter into,
incur liabilities, or hold itself out to third Parties as having the authority
to enter into and incur any contractual obligations, expenses or liabilities on
behalf of the other Party. Each of the Parties, in performing its obligations
under this Agreement is acting as an independent contractor of the other Party
and shall have exclusive control of the manner and means of performing such
obligations. Each Party shall be solely responsible for the supervision, daily
direction and control of its employees and for payment of their salaries
(including withholding of appropriate payroll taxes), worker's compensation,
disability, and other benefits. Under no circumstances shall the employees of
one Party be deemed to be employees of the other for any purpose.

            SECTION 15.8. Entire Agreement; Amendments. Except for the
Investment Agreement and the other agreements contemplated thereby, this
Agreement and the Exhibits and Schedules hereto contain the entire understanding
of the Parties with regard to the subject matter contained herein or therein,
and supersede all other prior representations, warranties, agreements,
understandings or letters of intent between or among the Parties. This Agreement
shall not be amended, modified or supplemented except by a written instrument
signed by an authorized representative of each of the Parties. Except as set
forth in Section 15.17 and except for the CareerBuilder Network and the Tribune
Newspapers (which are intended beneficiaries of this Agreement) this Agreement
is not intended to confer upon any Person other than the Parties hereto any
rights or remedies hereunder. The Parties acknowledge and agree that the fees
paid by the Tribune Newspapers ("Newspaper Fees") are part of the total
consideration received by AdStar under this Agreement.

            SECTION 15.9. Waivers. Any term or provision of this Agreement may
be waived, or the time for its performance may be extended, by the Party or
Parties entitled to the benefit thereof. Any such waiver shall be validly and
sufficiently authorized for the purposes of this Agreement if, as to any Party,
it is authorized in writing by the President of AdStar or by the President or
any vice president of Tribune, as the case may be. The failure of any Party to
enforce at any time any provision of this Agreement shall not be construed to be
a waiver of such provision, nor in any way to affect the validity of this
Agreement or any part hereof or the right of any Party thereafter to enforce
each and every such provision. No waiver of any breach of this Agreement shall
be held to constitute a waiver of any other or subsequent breach.

            SECTION 15.10. Expenses. Except as expressly set forth herein or in
the Investment Agreement and related agreements, each Party will pay all costs
and expenses

                                      -20-
<PAGE>

incident to its negotiation and preparation of this Agreement and to its
performance and compliance with all agreements and conditions contained herein
on its part to be performed or complied with, including the fees, expenses and
disbursements of its counsel and independent public accountants.

            SECTION 15.11. Partial Invalidity. Wherever possible, each provision
hereof shall be interpreted in such manner as to be effective and valid under
applicable law, but in case any one or more of the provisions contained herein
shall, for any reason, be held to be invalid, illegal or unenforceable in any
respect, such provision shall be ineffective to the extent, but only to the
extent, of such invalidity, illegality or unenforceability without invalidating
the remainder of such invalid, illegal or unenforceable provision or provisions
or any other provisions hereof, unless such a construction would be
unreasonable.

            SECTION 15.12. Execution in Counterparts. This Agreement may be
executed in counterparts, each of which shall be considered an original
instrument, but all of which shall be considered one and the same agreement, and
shall become binding when one or more counterparts have been signed by each
Party and delivered to each Party.

            SECTION 15.13. Headings. The section and article headings contained
in this Agreement are inserted for convenience of reference only and will not
affect the meaning or interpretation of this Agreement.

            SECTION 15.14. Notices. All notices or other communications required
or permitted hereunder shall be in writing and shall be deemed given or
