Re: $250,000,000 Senior Secured Credit Facilities - Commitment Letter

Ladies and Gentlemen:

      infoUSA Inc. (the "Borrower"), various lenders (the "Existing Lenders"),
and Wells Fargo Bank, National Association, as sole lead arranger, sole book
runner and administrative agent (in such capacity, the "Administrative Agent"),
are parties to a Credit Agreement dated as of March 25, 2004 (the "Existing
Credit Agreement"). Under the Existing Credit Agreement, the Existing Lenders
have extended $170 million of revolving and term credit.

      The Borrower has advised Wells Fargo Bank, National Association ("Wells
Fargo"), that it intends, through certain wholly-owned subsidiaries (the
"Acquisition Sub"), to acquire OneSource Information Services, Inc., a Delaware
corporation (the "Target"), by means of a tender offer for not less than 51% of
the outstanding shares of the Target followed by a merger (the "Acquisition").
The Borrower has also advised Wells Fargo that in connection with such
transaction, certain existing indebtedness of the Target will be refinanced (the
"Refinancing") and related premiums, fees and expenses (the "Fee and Expense
Payments") will be paid.

      The Acquisition, Refinancing, Fee and Expense Payments and other related
transactions are collectively referred to herein as the "Transaction". The
approximate amounts to be expended in connection with the Transaction, and
assuming that the Existing Credit Agreement is refinanced, are set forth in the
Sources and Uses Table attached as Addendum II to the Summary of Terms, Senior
Secured Credit Facilities (the "Senior Term Sheet") attached hereto as Annex A.
The term "Credit Parties" as used herein refers collectively to the Borrower,
the Target, the Acquisition Sub and all subsidiary guarantors of such companies
after giving effect to the consummation of the Transaction. The Senior Secured
Credit Facilities described in the Senior Term Sheet are referred to herein as
the "Senior Secured Credit Facilities".

      Wells Fargo is pleased to inform the Borrower that it hereby commits to
provide the entire principal amount of the Senior Secured Credit Facilities and
to act as the sole and exclusive lead arranger, administrative agent and sole
book runner (the "Lead

Arranger") for the Senior Secured Credit Facilities and to arrange for a
syndicate of financial institutions and other "accredited investors" (as defined
in SEC regulations; each such financial institution and accredited investor,
including Wells Fargo, being a "Lender" and, collectively, the "Lenders") to
participate in the Senior Secured Credit Facilities. The Lead Arranger shall
determine whether to amend the Existing Credit Agreement or to refinance the
indebtedness arising under the Existing Credit Agreement in connection with
providing the Senior Secured Credit Facilities.

      The Lead Arranger's fees for such services are set forth in the
accompanying confidential fee letter (the "Fee Letter"). The Borrower agrees
that no other agents or advisors will be engaged or appointed and no
compensation (other than that expressly contemplated by the Fee Letter) will be
paid for the placement of the Facilities unless the Borrower and the Lead
Arranger shall so agree.

      Wells Fargo is satisfied with the results of its diligence investigation
of the Borrower, the Target and their subsidiaries. Wells Fargo's commitment
shall not be subject to further diligence unless Wells Fargo shall become aware
of any information relating to conditions or events not previously disclosed to
Wells Fargo or constituting new information or additional developments
concerning conditions or events previously disclosed to Wells Fargo which, in
its judgment, is inconsistent with the information theretofore provided to Wells
Fargo and which Wells Fargo reasonably deems materially adverse in respect of
the condition (financial or otherwise), business, operations, debt service
capacity, properties, assets, accounting treatment, liabilities (including
environmental liabilities ) or prospects of the Borrower, the Target and their
subsidiaries.

      The foregoing commitment and all undertakings and agreements hereunder are
expressly subject to (i) no material adverse change in the business, assets,
condition (financial or otherwise), operations, liabilities (whether
contractual, environmental or otherwise), properties, Projections or prospects
of the Borrower and its subsidiaries taken as a whole or the Target since
December 31, 2003, or in the facts and information as represented to date, (ii)
no material disruption or material adverse change in the financial or capital
markets generally or in the market for syndicated credit facilities that could
in the sole discretion of the Lead Arranger be expected to materially adversely
affect the syndication of the Senior Secured Credit Facilities, (iii) the
satisfaction of the terms and conditions of this letter, the Senior Term Sheet
and the other annexes and schedules attached hereto (together, this "Commitment
Letter") and the Fee Letter in a manner acceptable to Wells Fargo, and (iv) the
absence of any competing offering, placement or arrangement for any debt
security or bank financing by or on behalf of any of the Credit Parties.

      The Lead Arranger will manage all aspects of the syndication, including
decisions as to the selection of institutions to be approached and when they
will be approached, when their commitments will be accepted, which institutions
will participate, the allocations of the commitments among potential Lenders,
any titles offered to potential Lenders and the amount and distribution of fees
among the Lenders. The Borrower agrees


infoUSA Inc.

that no other agents, co-agents or arrangers will be appointed, no other titles
will be awarded and no compensation other than as expressly set forth in the
Senior Term Sheet and the Fee Letter will be paid in connection with the Senior
Secured Credit Facilities unless the Borrower and the Lead Arranger shall so
agree. The Borrower shall actively assist the Lead Arranger in completing a
syndication satisfactory to it. Such assistance shall include (i) the Borrower
using reasonable efforts to ensure that the syndication efforts benefit
materially from the existing lending and investment banking relationships of the
Credit Parties, (ii) the Borrower using reasonable efforts to make certain
members of the management of the Credit Parties, as well as its consultants and
advisors, are available during regular business hours to answer questions
regarding the Senior Secured Credit Facilities, (iii) the Credit Parties
providing or causing to be provided to the Lead Arranger all information
reasonably deemed necessary by it to complete syndication and the Credit Parties
assisting in the preparation of a confidential informational memorandum to be
used in connection with the syndication, and (iv) the hosting by the Credit
Parties of meetings with prospective Lenders. Unless this letter is terminated
by the Lead Arranger or the Borrower, the Borrower also agrees to refrain from
any activity in the capital markets and the private placement market from the
date the Borrower signs this letter until the execution and delivery of the
Credit Agreement by the parties thereto (the "Closing") and the arrangement and
syndication has been successfully completed.

      The Borrower hereby represents that (i) all information, other than
Projections (as defined below), which has been or is hereafter made available to
the Lead Arranger or the other Lenders by any of the Credit Parties or any of
their representatives in connection with the transactions contemplated hereby
(the "Information") has been reviewed and analyzed by the Borrower in connection
with the performance of its own due diligence and is or will be, in the case of
Information made available after the date hereof, complete and correct in all
material respects and does not or will not contain any untrue statement of a
material fact or omit to state a material fact necessary to make the statements
contained therein not materially misleading in light of the circumstances under
which such statements were or are made, and (ii) all financial projections
concerning the Credit Parties that have been or are hereafter made available to
the Lenders by the Credit Parties or any of their representatives in connection
with the transactions contemplated hereby (the "Projections") have been or will
be, in the case of Projections made available after the date hereof, prepared in
good faith based upon reasonable assumptions. The Borrower shall supplement the
Information and the Projections from time to time until the closing date so that
the representation and warranty in the preceding sentence is correct on the
closing date. In arranging and syndicating the Senior Secured Credit Facilities,
Wells Fargo and each Lender that issues a commitment letter to provide a portion
of the Senior Secured Credit Facilities or agrees to amend the Existing Credit
Facility will be using and relying on the Information and the Projections
without independent verification thereof. The representations and covenants
contained in this paragraph shall remain effective until the initial funding
under a definitive financing agreement and thereafter the disclosure
representations contained herein shall be superseded by those contained in such
definitive financing agreement.

      The Borrower shall pay the Lead Arranger's reasonable costs and expenses
(including the reasonable fees and expenses of counsel (including allocated
costs of internal counsel), reasonable professional fees of consultants and
other experts and reasonable out-of-pocket expenses, including without
limitation syndication expenses) incurred before or after the date of this
Commitment Letter arising in connection with this Commitment Letter, the
definitive financing agreement, the syndication of the Senior Secured Credit
Facilities and the other transactions contemplated hereby.

      The Borrower shall indemnify and hold harmless the Lead Arranger and each
Lender (including Wells Fargo) and their respective affiliates and each
director, officer, employee, agent, attorney and affiliate thereof (each such
person, an "indemnified person") from and against any losses, claims, damages,
liabilities or other expenses to which an indemnified person may become subject,
insofar as such losses, claims, damages, liabilities (or actions or other
proceedings commenced or threatened in respect thereof) or other expenses arise
out of or in any way relate to or result from the Transaction, whether or not
actually completed and the other transactions contemplated by this Commitment
Letter, the Fee Letter, the extension of the financing contemplated hereby, the
Senior Secured Credit Facilities or any use or intended use of the proceeds of
any of the loans and other extensions of credit contemplated hereby, and to
reimburse each indemnified person for any reasonable legal or other expenses
incurred in connection with investigating, defending or participating in any
such investigation, litigation or other proceeding (whether or not any such
investigation, litigation or other proceeding involves claims made between any
Credit Party or any third party and any such indemnified person, and whether or
not any such indemnified person is a party to any investigation, litigation or
proceeding out of which any such expenses arise); provided, however, that the
indemnity contained herein shall not apply to the extent that it is determined
in a final nonappealable judgment by a court of competent jurisdiction that such
losses, claims, damages, liabilities or other expenses result from the gross
negligence or willful misconduct of such indemnified person. The obligations to
indemnify each indemnified person and to pay such legal and other expenses shall
remain effective until the initial funding under a definitive financing
agreement and thereafter the indemnification and expense reimbursement
obligations contained herein shall be superseded by those contained in such
definitive financing agreement. No indemnified person shall be liable for any
damages arising from the use by others of Information or other materials
obtained through internet, Intralinks or similar information transmission
systems in connection with the Senior Secured Credit Facilities. No indemnified
person shall be responsible or liable to any other party or any other person for
any indirect, consequential or special damages. The foregoing provisions of this
paragraph shall be in addition to any rights that any indemnified person may
have at common law or otherwise.

      Wells Fargo and its affiliates may be providing or proposing to provide
debt financing, equity capital or other services (including financial advisory
services) to other companies in respect of which the Credit Parties or their
affiliates may have conflicting interests because of the Transaction or other
relationships. The Borrower acknowledges that

confidential information to any Credit Parties.

to provide a portion of the Senior Secured Credit Facilities or agrees to amend
the Existing Credit Facility and each indemnified person and nothing in this
Commitment Letter or the Fee Letter, express or implied, shall give any person

hereunder. Neither this Commitment Letter nor the Fee Letter is assignable (and
any purported assignment shall be null and void) and neither may be relied upon

such disclosure prior to making such disclosure. The Lead Arranger hereby
consents to the disclosure of this Commitment Letter (but not the Fee Letter) on
a confidential basis to the Target and its financial and legal advisors for
their use in connection with their evaluation of the Borrower's proposal for the
Acquisition.

      If this Commitment Letter and the Fee Letter are not accepted by the
Borrower as provided for below, the Borrower shall immediately return this
Commitment Letter and the Fee Letter (and any copies hereof and thereof) to the

1.6011-4) of any of the transactions contemplated hereunder and all materials of
any kind (including opinions or other tax analyses) that are provided to Wells
Fargo, the Borrower or any of their respective affiliates (and any such

hereof to the contrary notwithstanding all of the Borrower's obligations
hereunder in respect of indemnification, confidentiality and fee and expense
reimbursement shall survive any termination of the commitments pursuant to this
paragraph.

      THIS COMMITMENT LETTER SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE

                        months for LIBOR loans, subject to availability.

                        default under the Senior Secured Credit Facilities at a
                        rate per annum of 2% above the applicable interest rate.
