termination occurs in the second or third year of the Term, a prorated portion
(on a per diem basis) of any LTIP the Executive would have received under
Section 3.3(a) in the third year of the Term based on the Approved Budget for
such year, or, if such termination occurs in the fourth or fifth year of the
Term, any LTIP the Executive would have received under Section 3.3(a) for the
year in which the termination took place based on the Approved Budget for such
year. 'Approved Budget' shall mean the detailed financial forecast of revenues,
operating income and management cash of the Company as approved by the CEO of

                  of RIAG not inconsistent with the other provisions of this
                  Agreement;

             f)   the commission by the Executive of any act or acts of
                  dishonesty reasonably determined by the CEO of RIAG to
                  render the Executive unfit for continued employment with the
                  Company; or

             g)   the failure of the Company to meet minimum financial

                  performance criteria as indicated on Schedule 3 attached
                  hereto, which Schedule 3 may be amended during the Term by
                  agreement of the Executive and the CEO of RIAG, subject to
                  approval by Thomson; and

             h)   for any other reason;

provided that termination of this Agreement under clauses (b) through (h) shall
be made upon written notice to the Executive by the Company. The Executive may

Agreement is terminated by the Executive for any reason following December 31,
1997 and prior to expiration of the Term, the Executive shall be entitled to

         5.  Certain Covenants of the Executive.

         5.1 Covenants. The Executive acknowledges that (i) the Company is
engaged and in the future will be engaged in the business of developing,
designing, publishing and selling compliance and other information products and
services for tax and accounting professionals as well as products and services
for third parties that integrate with products and services used by tax and
accounting professionals (all of the foregoing shall include, without
limitation, software, databases and consulting services of the type provided by
the Company) (the foregoing, together with any other businesses related to tax
and accounting professionals that the Company or its affiliates may engage in
from the date hereof to the date of the termination of this Agreement for which
the Executive has management responsibility under this Agreement, being
hereinafter referred to as the 'Company Business'); (ii) his services to the
Company will be special and unique; (iii) his work for the Company will give him
access to trade secrets of and confidential information concerning the Company;
(iv) the Company Business is national in scope; (v) the Company would not have
entered into this Agreement but for the agreements and covenants contained in
this Section 5; and (vi) the agreements and covenants contained in this Section

induce the Company to enter into this Agreement, the Executive covenants and
agrees that:

             5.1.1 Restrictive Covenants. In consideration for the payments to
the Executive contemplated hereunder, during the Term hereof and for a period
equal to three years after the termination or expiration of the Executive's
employment with the Company (the 'Restricted Period'), the Executive shall not,
other than as specifically provided in this Agreement, directly or indirectly,
(i) engage in the Company Business or a business competitive with the Company
Business; (ii) assist any person in conducting a business competitive with the
Company Business, provided, however, that this is not intended to restrict the
Executive's ownership of up to 5% of the securities of a publicly traded company
that engages in the Company Business; (iii) interfere with business
relationships (whether 

formed heretofore or hereafter) between the Company and customers of or
suppliers to the Company Business; and provided further that the obligations of
the Executive pursuant to this Section 5.1.1 shall terminate after the second
year of the Restricted Period. The Executive agrees that, in the event of a
breach or threatened breach by the Executive of this section, the Company shall
be entitled to injunctive relief restraining the Executive from engaging in any
of the aforesaid prohibited activities. Nothing hereunder, however, shall be
construed as prohibiting the Company from pursuing any other remedies available
to it in law or in equity.

             5.1.2 Confidential Information; Personal Relationships. During and
after the Restricted Period, the Executive shall keep secret and retain in
strictest confidence, and shall not use for the benefit of himself or others,
except in connection with the business and affairs of the Company and its
affiliates, all confidential information relating to the Company Business or to
the Company or to the business of any of the Company's affiliates, including,
but not limited to, 'know-how,' trade secrets, customer lists, subscription
lists, details of consultant contracts, pricing policies, operational methods,
marketing plans or strategies, product development techniques or plans, business
acquisition plans, technical processes, new personnel acquisition plans,
processes, designs and design projects, inventions, software, source codes,
object codes, system documentation and research projects and other business
affairs relating to the Company Business or to any affiliate of the Company
learned by the Executive heretofore or hereafter, and shall not disclose them to
anyone outside of the Company and its affiliates, either during or after
employment by the Company or any of its affiliates, except (i) as required in
the course of performing his duties hereunder, or (ii) with the Company's
express written consent, or (iii) pursuant to legal process. Notwithstanding the
foregoing, the obligations of the Executive pursuant to this Section 5.1.2 shall
not apply to confidential information:

         (a) which at the date hereof or thereafter becomes a matter of public
             knowledge without breach by the Executive of this Agreement; or

         (b) which is obtained by the Executive from a person other than the
             Company or an affiliate of the Company who is under no obligation
             of confidentiality to the Company. 

             5.1.3 Employees and Consultants of the Company. During the
Restricted Period, the Executive shall not, directly or indirectly, (a) hire,
solicit or encourage any employee to leave the employment of the Company or any
of its affiliates, (b) hire or enter into a consulting relationship with any
such employee who has left the employment of the Company or any of its
affiliates within three months of the termination of such employee's employment
with the Company or any of its affiliates, (c) solicit or encourage any
consultant to terminate a consulting relationship with the Company or any of its
affiliates or (d) hire or enter into a consulting relationship with any such
consultant who has terminated a consulting relationship related to the Company
Business with the Company or any of its affiliates within three months of the
termination of such consultant's relationship with the Company or any of its
affiliates; provided, however, that no provision of this Section 5.1.3 shall
prohibit any action the Executive may take with respect to Robert W. Nolan, Jr..

             5.1.4 Consequence of Termination. Upon termination of the
Executive's employment with the Company, all documents, records, notebooks, and
similar repositories of or containing trade secrets or intellectual property
then in the Executive's possession, including copies thereof, whether prepared
by the Executive or others, will be promptly returned to or left with the
Company.

         5.2 Rights and Remedies upon Breach. If the Executive breaches, or
threatens to commit a breach of, any of the provisions of Section 5.1 (the
'Restrictive Covenants'), the Company shall have the right and remedy to have
the Restrictive Covenants specifically enforced by any court having equity
jurisdiction, it being acknowledged and agreed that any such breach or
threatened breach will cause irreparable injury to the Company and that money
damages will not provide adequate remedy to the Company. Such rights and
remedies shall be in addition to, and not in lieu of, any other rights and
remedies available to the Company under law or in equity.

         5.3 Severability of Covenants. The Executive acknowledges and agrees
that the Restrictive Covenants are reasonable and valid in geographical and
temporal scope and in all other respects. If any court determines that any of
the Restrictive Covenants or any part thereof, is invalid or unenforceable, the
remainder of the Restrictive Covenants shall 

not thereby be affected and shall be given full effect, without regard to the
invalid portions.

         5.4 Blue-Pencilling. If any court determines that any of the
Restrictive Covenants, or any part thereof, is unenforceable because of the
duration or geographic scope of such provision, such court shall have the power
to reduce the duration or scope of such provision, as the case may be, and, in
its reduced form, such provision shall then be enforceable and shall be
enforced.

     6.  Intellectual Property. The Company shall be the sole owner of all the
products and proceeds of the Executive's services hereunder, including, but not
limited to, all materials, ideas, concepts, formats, suggestions, developments,
arrangements, packages, programs and other intellectual properties that the
Executive may acquire, obtain, develop or create in connection with and during
the term of the Executive's employment hereunder, free and clear of any claims
by the Executive (or anyone claiming under the Executive) of any kind or
character whatsoever. The Executive shall, at the request of the Company,
execute such assignments, certificates or other instruments as the Company may
from time to time deem necessary or desirable to evidence, establish, maintain,
perfect, protect, enforce or defend its right, title and/or interest in or to
any such properties.

     7.  Other Provisions.

         7.1 Consent to Jurisdiction and Service of Process. Any legal action,
suit or proceeding in equity or in law arising out of or relating to this
Agreement and the transactions contemplated hereby or thereby shall be

in any such action, suit or proceeding, any claim that such party is not subject
personally to the jurisdiction of such court, that its property is exempt or
immune from attachment, that the action, suit or proceeding is brought in an
inconvenient forum, that the venue of the action, suit or proceeding is
improper, or that this Agreement may not be enforced in or by such court. Each
party further irrevocably submits to the jurisdiction of any such court in any
such action, suit or proceeding. Nothing herein contained shall be deemed to
affect the right of any party to serve process in any manner permitted by law.

                                  Annual Bonus

A.   Calculations: Revenue, Operating Income and Management Cash shall each be 
as determined in accordance with generally acceptable accounting principles
consistently applied, calculated and certified by the chief financial officer of
the Company and approved by the CEO of RIAG. The CEO of RIAG will deliver a
certificate of determination of Revenue, Operating Income and Management Cash to
the Executive no later than ninety days after the end of each respective
calendar year during the Term.

     The financial targets included herein have been developed using the
financial accounting policies adopted by the Company at the time of the Merger
Agreement, utilizing a January 31 fiscal year end. The effect on the targets of
any adjustments to these policies and a change to a calendar year end will be
quantified and will adjust the targets as agreed between the CEO of RIAG and the
Executive.

     Any payments of Annual Bonus amounts are funded out of the operating
results of the Company and are included in the calculation of Operating Income
to arrive at the Annual Bonus amount.

     The Annual Bonus amount will be calculated by applying the percentage bonus
earned (using the financial targets in B. below and the pro forma bonus schedule
in C. below) to the salary of the Executive in effect during the relevant
calendar year.

     The Executive will not be eligible for any payments unless the 'Floor'
targets for both Revenue and Operating Income for the relevant year as
identified in B. below are met or exceeded.

B.   Financial Targets

The financial targets for each fiscal year under the Agreement are as follow
(note: 1996 relates to the fiscal year ending January 31, 1997, et seq.):

(ii) Percentage Bonus Schedule for years 1997 through 2000 will be prepared on a
     consistent basis with the Percentage Bonus Schedule for 1996 using the
     relevant financial targets for each of those years.

D.   Treatment of Acquisitions: Acquisitions with revenues of up to $1.0 million
will be included in the results of the ongoing operations at the Company and the
targets used herein will not be adjusted. The targets used herein will be
adjusted to include the Revenue, Operating Income and Management Cash included
in the approved Thomson Board Papers for each acquisition with revenues in
excess of $1.0 million.

E.   Treatment of Changes in Operations: The targets used herein are based on 
the existing operations of the Company, as such may change in the ordinary
course of business. The targets may be adjusted for any extraordinary changes
including, but not limited to, product transfers to/from the Company and
significant new investment in product development funded by Thomson.

F.   Payment: Payment of the Annual Bonus pursuant to Section 3.3(a) and this
Schedule 1 shall be made as soon as practicable after the determination of
Revenue, Operating Income and Management Cash for the relevant period as

                                   SCHEDULE 2

                                      LTIP

A.   Calculations: Revenue and Operating Income shall each be as determined in
accordance with generally acceptable accounting principles consistently applied,
calculated and certified by the chief financial officer of the Company and
approved by the CEO of RIAG. The CEO of RIAG will deliver a certificate of
determination of Revenue and Operating Income to the Executive no later than
ninety days after the end of each respective calendar year during the Term.

     The financial targets included herein have been developed using the
financial accounting policies adopted by the Company at the time of the Merger
Agreement, utilizing a January 31 fiscal year end. The effect on the targets of
any adjustments to these policies and a change to a calendar year end will be
quantified and will adjust the targets as agreed between the CEO of RIAG and the
Executive.

     Any payments of LTIP amounts are funded out of the operating results of the
Company and are included in the calculation of Operating Income to arrive at the
LTIP amount.

     The LTIP amount will be calculated as provided below. The Executive will
not be eligible for any payments unless the 'Floor' targets as identified in B.
below for the relevant year are met or exceeded.

B.   LTIP Formula: Executive will be eligible to begin receiving payments of the
LTIP if the minimum ('Floor') Revenue and Operating Income targets are achieved
as outlined below. All dollar amounts are in thousands of U.S. dollars.

                                       Targets will not be adjusted.

   Revenues greater than $1.0 Million: Operating Income targets for each year
                                       of the Agreement will be increased by 
                                       12% of the purchase price of the 
                                       acquisition. Revenue targets will not 
                                       be adjusted.

(iv) Treatment of Changes in Operations: The targets used herein are based on
the existing operations of the Company, as such may change in the ordinary
course of business. The targets may be adjusted for any extraordinary changes

withholdings.

                                   SCHEDULE 3

Minimum Company Financial Performance Criteria:

The Company's minimum financial performance criteria require that Revenue and
Operating Income for each calendar year during the Term must exceed the previous
year's Revenue and Operating Income by at least 5% and 10% respectively. The
calculation for 1996 will be based on the Company's fiscal year 1995 results,
except that in no event will the minimum Revenue and Operating Income
requirements for 1996 be less than $20 million and $3.75 million respectively.
Notwithstanding the foregoing, if the minimum growth rates are not met but the
Company's overall performance exceeds the financial targets included in Schedule
1 (Section B.), then the Company's financial performance will be considered
acceptable for purposes of this Schedule.

                                  Attachment A

                              CONSULTING AGREEMENT

    CONSULTING AGREEMENT (the 'Agreement'), dated January __, 1996 between
Thomson Information Services, Inc. (the 'Company') and Robert W. Nolan, Sr. (the
'Consultant').

    The Consultant has served as a key executive of SCS/Compute, Inc., an
affiliate of the Company, and in recognition thereof it is the desire of the
Company and the Consultant to enter into this Agreement in order to ensure that
the services and advice of the Consultant will be available to the Company for
the term of the Agreement and to reward the Consultant for his continuing
contributions to the success of the Company on the terms and subject to the
conditions hereinafter set forth.

    Accordingly, the parties agree as follows:

    1. Consulting Engagement. The Company hereby engages the Consultant for the
Consulting Period (as defined in Section 2) to perform such consulting, advisory
and other services as the Consultant shall reasonably be requested to perform by
the Chief Executive Officer of Research Institute of America Group. The
Consultant hereby accepts such engagement and shall render the services
described above.

    2. Consulting Period. This Agreement shall take effect, and the term of the
Consultant's engagement under this Agreement shall commence, as of the earlier
of the date of termination of Consultant's employment pursuant to Section 4.1 of
the Employment Agreement between the Consultant and the Company dated January
__, 1996 (the 'Employment Agreement') and expiration of the Term of the
Employment Agreement (as such term is defined in Section 2 of the Employment
Agreement) (the 'Effective Date') and shall end on the third anniversary of the
Effective Date (the 'Consulting Period').

    3. Compensation.

       3.1 Fee. As compensation for all services to be rendered during the
Consulting Period pursuant to this Agreement, the Company shall pay the
Consultant a total fee of $1,050,000. Such fee shall be payable in the following
amounts at the following times: (i) during the period commencing on the
Effective Date and ending on the second anniversary of the Effective Date, an
annual amount of $400,000 payable monthly in arrears; and (ii) during the period
commencing on the date immediately following the second anniversary of the
Effective Date and ending on the third anniversary of the Effective Date, an
annual amount of $250,000 payable monthly in arrears.

       3.2 Expenses. The Consultant shall be entitled to be reimbursed for
reasonable expenses actually incurred or paid by the Consultant in the
performance of the Consultant's services during the Consulting Period under this
Agreement.

    4. Independent Contractor. The Consultant acknowledges that he is being
retained by the Company as an independent contractor and not as an employee. The
Company shall not exercise direction or control over the Consultant in his
performance of services hereunder. Accordingly, the Consultant hereby
acknowledges: (i) the Consultant shall be solely responsible for and shall file,
on a timely basis, tax returns and payments required to be filed with or made to
any relevant tax authorities with respect to his performance of services
hereunder; (ii) the Company will not withhold any taxes from compensation paid
by the Company to the Consultant during the Consulting Period unless legally
required to do so; (iii) the Consultant will be responsible for providing his
own office space; and (iv) the Company will not provide the Consultant during

long-term disability insurance or (d) any other employee benefits, rights or
entitlements under any plans of the Company or of SCS/Compute, Inc.. The
Company's only obligations under this Agreement are to pay the Consultant the
compensation and expenses described in Section 3 hereof.

    5. No Agency. Nothing contained in this Agreement shall be construed as
creating an agency relationship between the Company and the Consultant and,
without the Company's prior written consent, the Consultant shall have no
authority hereunder to bind the Company or make any commitments on the Company's
behalf. The Consultant shall not take any action in connection with his
rendering of services hereunder which he reasonably believes would cause any
third party to assume that he has such authority.

    6. Certain Covenants of the Consultant. The Consultant acknowledges that his

obligations pursuant to Sections 5, 6 and 7.1 of the Employment Agreement are
ongoing; provided, however, that any breach by the Executive of such Sections 5,
6 and 7.1 of the Employment Agreement shall not, without more, be deemed a
breach of this Agreement.

         Upon termination of the Consultant's engagement hereunder, all
documents, records, notebooks, and similar repositories of or containing trade
secrets or intellectual property then in the Consultant's possession, including
copies thereof, whether prepared by the Consultant or others, will be promptly
returned to or left with the Company.

         The Company shall be the sole owner of all the products and proceeds of
the Consultant's services hereunder, including, but not limited to, all
materials, ideas, concepts, formats, suggestions, developments, arrangements,
packages, programs and other intellectual properties that the Consultant may
acquire, obtain, develop or create in connection with and during the term of the
Consultant's engagement hereunder, free and clear of any claims by the
Consultant (or anyone claiming under the Consultant) of any kind or character
whatsoever. The Consultant shall, at the request of the Company, execute such
assignments, certificates or other instruments as the Company may from time to
time deem necessary or desirable to evidence, establish, maintain, perfect,
protect, enforce or defend its right, title and/or interest in or to any such
properties.

    7. Rights and Remedies upon Breach. If the Consultant breaches, or threatens
to commit a breach of, any of the provisions of Section 5 or 6 of this
Agreement, the Company shall have the right and remedy to have the Consultant's
obligations pursuant to such Sections specifically enforced by any court having
equity jurisdiction, it being acknowledged and agreed that any such breach or
threatened breach will cause irreparable injury to the Company and that money
damages will not provide adequate remedy to the Company. Such rights and
remedies shall be in addition to, and not in lieu of, any other rights and
remedies available to the Company under law or in equity.

    8. Other Provisions.

       8.1 Consent to Jurisdiction and Service of Process. Any legal action,
suit or proceeding in equity or in law arising out of or relating to this

immune from attachment, that the action, suit or proceeding is brought in an
inconvenient forum, that the venue of the action, suit or proceeding is
improper, or that this Agreement may not be enforced in or by such court. Each
party further irrevocably submits to the jurisdiction of any such court in any
such action, suit or proceeding. Nothing herein contained shall be deemed to
affect the right of any party to serve process in any manner permitted by law.
