days every three months during the last eighteen months of the Term to perform
the Consulting Services. The Consulting Services will be performed at such times

         5. Fees. As compensation for the Consulting Services, the Company or

<PAGE>

                  (b) The Company may terminate this Consulting Agreement for
any reason upon providing sixty (60) days' advance written notice to Best.

                  (c) Best may terminate this Consulting Agreement and be
released from providing services to the Company for the remainder of the
Consulting Period only for "Good Reason," which shall be found if, and only if,
the Company engages in a material breach of its obligations under this
Consulting Agreement which is not remedied by the Company within forty five (45)
days after receipt of notice thereof given by Best. Notwithstanding the
foregoing, it is agreed between the parties that "Good Reason" shall include a
change in the management of ProQuest Company that results in Alan Aldworth no
longer being employed by the Company. A termination of this Consulting Agreement
by Best for "Good Reason" under this Section 6(c) shall be accomplished by
giving the Company's Chief Executive Officer, General Counsel and Senior Vice
President of Human Resources written notice of the termination, setting forth in
reasonable detail the specific conduct of the Company that constitutes Good
Reason. An event shall not be deemed to constitute Good Reason if Best fails to
deliver such notice of termination for Good Reason within twenty days of Best's
actual knowledge of such event.

         7. Status. Best acknowledges and agrees that his status at all times
during the Consulting Period shall be that of an independent contractor, and
that he may not, at any time, act as a representative for or on behalf of the
Company or Voyager for any purpose or transaction, and may not bind or otherwise
obligate the Company or Voyager in any manner whatsoever without obtaining the
prior written approval of an authorized representative of the Company or
Voyager. Best hereby waives any rights to be treated as an employee or deemed
employee of the Company or any of its affiliates for any purpose following his
termination of employment at the Effective Date. The parties hereby acknowledge

<PAGE>

and agree that the compensation provided for in Section 5 shall represent fees
for Best's Consulting Services as an independent contractor, and shall be paid
without any deductions or withholdings for taxes. Best further acknowledges that
the Company and Voyager make no warranties as to any tax consequences regarding
payment of compensation under this Consulting Agreement, and specifically agrees
that the determination of any tax liability or other consequences of the payment
set forth above is his sole and complete responsibility and that Best will pay
all federal, state and local taxes, if any, assessed on such payments.

         8. Governing Law; Consent to Jurisdiction. This Agreement shall be
governed by and construed and enforced in accordance with the laws of the State
of Texas, excluding any conflicts or choice of law rule or principle that might
otherwise refer construction or interpretation of this Consulting Agreement to
the substantive law of another jurisdiction.

         9. Assignability. Best may not assign or transfer this Consulting
Agreement or any of Best's rights, duties or obligations hereunder. The Company,
Voyager or both may assign this Consulting Agreement to any affiliate thereof or
to any person or entity acquiring all or substantially all of the assets (by
merger or otherwise) of the Company, Voyager or any such affiliate so long as
such person, entity or affiliate assumes the Company's obligations hereunder.

         10. Entire Agreement. This Consulting Agreement and the Non-Compete
Agreement constitute the full and complete understanding and agreement of the
parties hereto with respect to engaging Best as a consultant to the Company and
