AGREEMENT

         This Agreement (the "Agreement") is made and entered into as of
January ____, 2004 by and between OneSource Information Services, Inc., a
Delaware corporation (the "Company"), and _______________________ (the
"Employee").

RECITALS

A. The Company considers it consistent with the best interests of the Company's
   stockholders to foster the continuous at-will employment of key management
   personnel and recognizes that the possibility of a change of control of the
   Company may exist and that such possibility, and the uncertainty and
   questions which it may raise among management, may result in the departure
   or distraction of management personnel to the detriment of the Company and
   its stockholders.

B. The Company desires to provide members of the Company's management,
   including the Employee, with an incentive to continue their respective
   at-will employment and to maximize the value of the Company upon a change of
   control for the benefit of the Company's stockholders.

In consideration of the foregoing, the mutual covenants set forth herein and
   the continued employment of the Employee, the parties agree as follows:

        1.      Definitions. As used in this Agreement, the following terms
                shall have meanings set forth herein:

        (a)     A termination for "Cause" means a termination of the Employee's
                employment by the Company for one or more of the following
                reasons:

                (i)     the substantial and continuing failure or refusal of the
        Employee, after notice thereof, to perform his or her job duties and
        responsibilities (other than failure or refusal resulting from
        incapacity due to physical disability or mental illness);

                (ii)    disloyalty, gross negligence, willful misconduct, or
        breach of fiduciary duty to the Company;

                (iii)   the commission of an act of embezzlement,
        misappropriation or fraud;

                (iv)    deliberate disregard of the rules or policies of the
        Company which results in direct or indirect material loss, damage or
        injury to the Company;

                (v)     the unauthorized disclosure of any confidential,
        proprietary and/or trade secret information of the Company or its
        customers;

                (vi)    the commission of an act which constitutes unfair
        competition with the Company or which induces any customer or supplier
        to break a contract with the Company;

                (vii)   the material breach of any written agreement between the
        Employee and the Company, including, but not limited to, the Employment
        and Confidentiality Agreement between the Employee and the Company; or

                (viii)   the conviction, or plea of nolo contendere, by the
        Employee of a felony.

        (b)     "Change of Control" means:

                (i)     a transaction or series of transactions resulting in a
         "person" (as such term is used in Sections 13(d) and 14 (d) of the
         Securities Exchange Act of 1934 (the "Exchange Act")), becoming the
         "beneficial owner" (as defined in Rule 13d-3 promulgated under the
         Exchange Act), directly or indirectly, of more than 50% of (A) the
         outstanding shares of common stock of the Company or (B) the combined
         voting power of the Company's then-outstanding securities; or

<PAGE>

                (ii)    a merger, consolidation, business combination or other
         reorganization to which the Company is a party (except one in which
         the holders of the outstanding capital stock of the Company
         immediately prior to such merger, consolidation, business combination
         or other reorganization continue to hold at least a majority of the
         capital stock and voting power of the surviving entity thereafter); or

                (iii)   a sale of all or substantially all of the assets of the
         Company when the assets are sold as a going concern.

         (c)    "Change of Control Effective Date" means the date of
effectiveness of a Change of Control.

         (d)    A termination for "Good Reason" means a termination of the
Employee's employment by the Employee following the occurrence of any of the
following events without the Employee's written consent:

                (i)     a reduction in the Employee's then-current base salary
         or bonus target (other than in connection with a salary adjustment or
         bonus target adjustment generally applicable to similarly situated
         senior management employees); or

                (ii)    any failure to offer the Employee the kind or level of
         benefits offered to similarly situated senior management employees; or

                (iii)   a significant diminution in the Employee's duties or
         responsibilities which results in the assignment of the Employee to a
         position inconsistent with the Employee's substantive area of
         expertise and experience; or

                (iv)    the relocation of the Employee's primary business
         location to a location greater than 35 miles from the Employee's
         then-current primary business location; or

                (v)     the failure to pay the Employee any portion of his or
         her current base salary, bonus or other deferred compensation within
         five (5) days of the date such compensation is due, based upon the
         payment terms currently in effect.

         (e)    "Permanent Disability" means that (i) the Employee has been
incapacitated by bodily injury or disease so as to be prevented thereby from
engaging in the performance of the Employee's duties, (ii) such incapacity has
continued for a period of six consecutive months, and (iii) such incapacity
will, in the opinion of a qualified physician, be permanent and continuous
during the remainder of the Employee's life.

         2.     Severance Benefits Upon Termination After a Change of Control.
If at any time within twelve (12) months after the Change of Control Effective
Date or on or within three (3) months prior to the Change of Control Effective
Date, Employee's employment is terminated either (i) by the Company for any
reason other than for Cause or the Employee's Permanent Disability or death or
(ii) by the Employee for Good Reason, (such events of termination referred to
herein as an "Involuntary Termination"), the Company shall pay or provide the
Employee with the following:

                (i)     all base salary and accrued but unused vacation up to
         and through the date of Involuntary Termination shall be paid in
         accordance with the Company's normal payroll payment practices as
         currently in effect; and

                (ii)    (a) if the Involuntary Termination occurs on or before
         the 180th day following the Change of Control Effective Date,
         severance from the Company in an amount equal to the sum of (A) the
         Employee's then-current monthly base salary, multiplied by 12, (B) the
         average annual bonus awarded to the Employee over the three (3) years
         prior to the Change of Control Effective Date, and (C) an amount equal
         to the matching contribution paid by the Company to his or her account
         under the Company's 401(k) Plan for the calendar year immediately
         preceding the date of such Involuntary Termination, which severance
         shall be paid as a lump sum within thirty (30) days of such
         Involuntary Termination; or (b) if the Involuntary Termination occurs
         after the 180th day but on or before the 270th day following the
         Change of Control Effective Date, severance from the Company equal to
         the Employee's then-current monthly base salary, multiplied by nine
         (9), which severance shall be paid as a lump sum within thirty (30)
         days of such Involuntary Termination; or (c) if the Involuntary
         Termination occurs after the 270th day but on or before the 365th day
         following the Change of Control Effective Date, severance from the
         Company equal to the Employee's then-current monthly base salary,
         multiplied by six (6), which severance shall be paid as a lump sum
         within thirty (30) days of such Involuntary Termination.

<PAGE>

                (iii)   payment of Employee's health and dental insurance from
         the date of the Employee's termination through the 12-month
         anniversary of the Change of Control Effective Date (pro-rated for any
         partial month), provided the Employee elects to continue such health
         and dental insurance in accordance with the applicable provisions of
         the Consolidated Omnibus Budget Reconciliation Act of 1985 ("COBRA");
         and

                (iv)    continuation of coverage under the Company's life and
         disability insurance plans, if any, to the extent permitted by
         applicable law and the terms and conditions of such plans, until the
         12-month anniversary of the Change of Control Effective Date;
         provided, however, that in the event such continuation of coverage is
         not so permitted, the Employee acknowledges and agrees that he or she
         shall not be entitled to any payments in lieu thereof.

         The Company's obligation to provide the payments as set forth in this
Section 2 shall be subject to, and conditioned upon, the Employee's prior
execution of a full release of claims in form reasonably satisfactory to the
Company, providing for, among other things, the release of the Company, its
directors, officers, shareholders, employees and agents, and its and their
respective successors and assigns from any claims arising from or relating to
the Employee's employment or severance from employment with the Company (and/or
its successors and assigns), including any claims arising from this Agreement
through the date of such release.

         The Employee shall not be required to mitigate the amount of any
payment to be paid or provided in this Section 2 by seeking other employment or
otherwise, nor shall the amount of any payment or benefit provided by this
Section 2 be reduced by any compensation earned by the Employee as a result of
employment by another employer, by retirement benefits, by offset against any
amount claimed to be owed by the Employee to the Company, or otherwise.

         3.     Noncompetition. The Employee agrees that, upon and subject to
the Employee's receipt of the payments and benefits set forth above, (x) for a
period of twelve (12) months following an Involuntary Termination that occurs
on or before the 180th day following the Change of Control Effective Date; or
(y) for a period of nine (9) months following an Involuntary Termination that
occurs after the 180th day but on or before the 270th day following the Change
of Control Effective Date; or (z) for a period of six (6) months following an
Involuntary Termination that occurs after the 270th day but on or before the
365th day following the Change of Control Effective Date (such period described
in (x), (y) or (z), as applicable, referred to herein as the "Noncompete and
Nonsolicit Period"), the Employee shall not, anywhere in the United States,
have any Business Relationship (as defined below) with any entity, including,
but not limited to, any corporation, partnership, limited liability company,
sole proprietorship, joint venture or unincorporated business (whether or not
for profit) (such entity, a "Business"), which has products and services that
are being sold or provided that are competitive with the products and services
of the Company planned or being sold or provided by the Company as of the date
of the Involuntary Termination. The Employee will be deemed to have a "Business
Relationship" with a Business if the Employee (a) owns, manages, operates,
joins or is employed by the Business, (b) is a director, member, agent,
shareholder, owner or partner of the Business, (c) acts as a consultant or
advisor to the Business, or (d) controls or participates in the ownership,
management or operation of the Business; provided, however, that nothing herein
shall prevent the Employee from acquiring, solely as an investment through
market purchases, (i) less than 5% of the outstanding equity securities of any
corporation that are registered under the Exchange Act and that are publicly
traded, or (ii) shares or interests in any public or private mutual fund;
provided that the Employee is not part of any control group of such corporation
or mutual fund.

         4.     Nonsolicitation. Upon and subject to the Employee's receipt of
the payments and benefits set forth in Section 2, during the Noncompete and
Nonsolicit Period, the Employee will not, directly or indirectly, (a) solicit
or do business with any entity that at such time is, or at any time in the
3-month period prior to such time had been, a customer of the Company, or (b)
solicit, recruit, influence, entice or encourage any person who at such time
is, or who at any time in the 3-month period prior to such time had been, an
employee of, or consultant to, the Company to cease or curtail his or her
relationship therewith.

         5.     Equitable Relief. The Employee acknowledges that the Company's
remedies at law for breach of the provisions of Section 3 or Section 4 of this
Agreement would be inadequate, and, in recognition thereof, the Employee agrees
that, in the event of such breach, in addition to any remedies at law it may
have, the Company, without posting any bond, shall be entitled to seek
equitable relief in the form of specific performance, a temporary restraining
order, a temporary or permanent injunction, or any other equitable remedy that
may be available to it.

         6.     At-Will Employment. The Employee acknowledges and agrees that
this Agreement does not in any way modify or limit the at-will nature of the
Employee's employment with the Company. Nothing in this Agreement should be
taken as a limit on payments that may be made to the Employee or as a guarantee
of continued employment, a specific term of employment and/or a contract of
employment, and at all times either the Employee or the Company may terminate
the Employee's employment with the Company at any time, for any or no reason,
and with or without prior notice.

         8.     Assignment and Expiration of Agreement.

         (a)    The Employee acknowledges and agrees that this Agreement is
personal to the Employee and the Employee may not assign any rights or delegate
any obligations or duties hereunder; provided that this Agreement shall inure
to the benefit of and be enforceable by the Employee and his or her personal or
legal representatives, executors, administrators, heirs, distributees, devisees
and legatees.

         (b)    This Agreement, and the rights and obligations of the Company
hereunder, shall inure to the benefit of, and shall be binding upon, any
successor or assign of the Company or all or substantially all of the business
and/or assets of the Company (whether direct or indirect, by merger, purchase,
consolidation, operation of law or otherwise) and may be assigned by the
Company to any entity that shall succeed to the business and assets of the
Company. As used in this Agreement, "Company" shall mean the Company as defined
herein and any successor to the Company or its business and/or assets as

within twelve (12) months of the date thereof.

         9.     Governing Law. The Employee and the Company agree that this
Agreement shall be interpreted in accordance with and governed by the laws of

         10.    Entire Agreement. This Agreement shall supersede all prior,
concurrent and/or contemporaneous arrangements, whether written or oral,
regarding the subject matter of this Agreement; provided, however, that this
Agreement is not intended to and shall not affect, limit or terminate the
Employment and Confidentiality Agreement between the Employee and the Company.

         11.    Acknowledgements. The Employee acknowledges that he or she is
not relying and has not relied on any promise, representation or statement made
by or on behalf of the Company which is not set forth in this Agreement. The

continuity of the Company's business, trade secrets and goodwill, and as such,
the Employee agrees that the restrictions set forth in such sections are
reasonable as to time and scope.

         12.    Severability. If any one or more of the provisions (or any part
thereof) of this Agreement shall be declared invalid, illegal or unenforceable
to any extent by a court of competent jurisdiction, then the application of
such provision in such circumstances shall be modified to permit its
enforcement to the maximum extent permitted by law, and both the application of
such portion or provision in circumstances other than those as to which it is
so declared invalid, illegal or unenforceable and the remainder of this
Agreement shall not be affected thereby, and each of the remaining provisions
(or any part thereof) shall be valid and enforceable to the fullest extent
permitted by law.

         13.    Waiver; Modification; Amendment. No waiver of any provision of
this Agreement shall be effective unless made in writing and signed by the
