NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)



1.       INTERIM UNAUDITED FINANCIAL INFORMATION

                  The consolidated  financial statements include the accounts of
         Walsh  International  Inc. and all of its  majority-owned  subsidiaries
         other  than  the  Source  Business.  The  "Source  Business",  which is
         accounted for as discontinued operations (see Note 3), includes a range
         of products and  services,  primarily  marketed  under the name Source,
         that utilize proprietary databases of prescriptions dispensed by retail
         outlets in the United States.  The  Consolidated  financial  statements
         have been restated for discontinued operations.

                  The accompanying consolidated statements of operations for the
         three and nine months ended March 31, 1996 and 1995,  the  consolidated
         statements  of cash flows for the nine months  ended March 31, 1996 and
         1995,  the  consolidated  balance  sheets as of March 31,  1996 and the
         related   information  of  Walsh  International  Inc.  (the  "Company")
         included in these notes to the  consolidated  financial  statements are
         unaudited.  In  the  opinion  of  management,   the  interim  financial
         information  reflects all  adjustments  (consisting  only of items of a
         normal recurring nature except for discontinued  operations)  necessary
         for  the  fair  presentation  of the  financial  position,  results  of
         operations  and  cash  flows  for the  periods  presented.  Results  of
         continuing  operations  for the three and nine  months  ended March 31,
         1996 are not  necessarily  indicative of the results to be expected for
         the entire year.

                  The June 30, 1995 balance sheet was derived from the Company's
         June 30, 1995 audited consolidated  financial statements,  but does not
         include all  disclosures  required  by  generally  accepted  accounting
         principles,  and includes certain reclassifica- tions to conform to the
         unaudited March 31, 1996 balance sheet.

                  These  interim   financial   statements   should  be  read  in
         conjunction  with the audited  consolidated  financial  statements  and
         related notes thereto included in the Company's  Registration Statement
         on Form S-1.


2.       PRO FORMA BALANCE SHEET

                  The Pro Forma  Balance  Sheet as of March 31, 1996 is included
         to reflect the estimated effects of the Spin-Off of the Source Business
         to its stockholders (the "Spin-Off");  the proceeds  generated from the
         initial public offering of the Company's



                                        6

<PAGE>
         Common Stock, including the over-allotment, and the use of a portion of
         the proceeds to retire the Company's subordinated debentures.

                  As of April 16, 1996,  the Company  consummated  the Spin-Off.
         Pursuant to an agreement  with the holders of the Preferred  Stock,  at
         the time of the  Spin-Off,  one-half of the shares of  Preferred  Stock
         were  exchanged  for  shares  of  preferred   stock  of  Source  having
         substantially  similar terms, and the redemption price of the Preferred
         Stock was  increased  to $25.34.  Based on the  relative  fair value of
         Walsh and Source,  $11,802,000 of  obligations  of the Preferred  Stock
         were  transferred  to Source  as part of the  Spin-Off.  The  remaining
         issued and outstanding Preferred Stock after the Spin-Off was converted
         into   1,486,252   shares  of  Common  Stock   concurrently   with  the
         consummation of the offering.

                  The unaudited  Pro Forma Balance Sheet  reflects the impact of
         the Spin-Off. In addition to the transaction described in the preceding
         paragraph and the  identifiable  net liabilities of the Source Business
         as  described  in Note 3, the Company  contributed  the  Pharmaceutical
         Marketing Services Inc. ("PMSI") shares, certain other corporate assets
         and  cash  to fund  the  working  capital  requirements  of the  Source
         business.

                  The consummation of the initial public offering, including the
         over-allotment,  resulted in the  issuance of  3,186,091  shares of the
         Company's   Common  Stock  and  the   generation  of  net  proceeds  of
         approximately  $34.8 million.  The Company has used approximately $14.2
         million of the net proceeds to repay its  subordinated  debentures  due
         March 31, 1997 and intends to use approximately $0.5 million of the net
         proceeds  to repay the  remainder  of those  debentures.  The Pro Forma
         Balance Sheet reflects the above transactions.


3.       DISCONTINUED OPERATIONS - SOURCE BUSINESS

                  The Company  consummated  the Spin-Off on April 16, 1996. This
         was  accomplished by the distribution of all the issued and outstanding
         capital stock of Source to the Company's shareholders.

                  As a result of the above, results of operations of Source have
         been reclassified as discontinued operations.

                  The loss in the nine months  ended March 31, 1996  includes an
         estimate of the losses expected to be incurred form the Source business
         from April 1, 1996 through the date of the Spin-Off of $192,000.

                  The revenues for the discontinued operations were $12,470,000,
         $11,366,000,  $37,805,000  and  $36,969,000  for the three months ended
         March 31,  1996 and 1995 and for the nine  months  ended March 31, 1996
         and 1995, respectively.

4.       PRO FORMA INCOME (LOSS) PER SHARE

                  Pro  Forma  income  (loss)  per  share is  computed  using the
         weighted average number of shares of Common Stock  outstanding.  Common
         equivalent  shares from the  Preferred  Stock  (using the  if-converted
         method)  and stock  options  and  warrants  (using the  treasury  stock
         method) have been included in the  computation  where dilutive  (except
         that,  pursuant to the Securities and Exchange  Commission  rules,  the
         Preferred  stock which was  converted  into Common Stock in  connection
         with the Company's  initial public offering is included as if converted
         even though inclusion may be anti-dilutive).

                  Pursuant  to  a  Securities  and  Exchange   Commission  Staff
         Accounting Bulletin,  all Common and Common equivalent shares issued by
         the Company at an exercise price below the public offering price during
         the twelve-month period prior to the offering have been included in the
         calculation  as if  they  were  outstanding  for  all  periods  through
         December 31, 1995,  the interim  period  included in the initial public
         offering  prospectus  (using the treasury  stock method and the initial
         public  offering  price of  $12.00  per share  for  stock  options  and
         warrants).  After  December  31,  1995,  Common  equivalent  shares are
         included  only if they have a  dilutive  effect.  The Pro Forma  Income

5.       INCOME TAXES

                  For the  three  and  nine  months  ended  March  31,  1996 the
         effective  tax rates were 89% and 18%  respectively  compared  to a tax
         provision on a loss for the  equivalent  periods of fiscal 1995.  These
         rates were 56% and 8% after adding back the  debenture  interest  which
         will  not  be a  continuing  expense  and  is not  deductible  for  tax
         purposes.  The  effective  income  tax rate is  based on the  Company's
         projected mix of the profits of its subsidiaries operating in different
         countries.

Item 2.             MANAGEMENT'S DISCUSSION AND ANALYSIS OF RESULTS OF
                             OPERATIONS AND FINANCIAL CONDITION
                          WALSH INTERNATIONAL INC. AND SUBSIDIARIES



              Three Months Ended March 31, 1996 and March 31, 1995

         Revenue for the  Company's  third quarter of fiscal year 1996 was $12.1
million,  an increase of 20% over the  comparable  period of the prior year. The
increase was  principally  due to a 21% increase in PRECISE  revenues.  Although
lower as a percentage of revenue,  increased  direct mail  marketing  sales also
contributed  to the higher  revenues.  Currency  exchange  rates had no material
impact on the level of increase.

         Production  costs  in the  third  quarter  were  $4.7  million  (39% of
revenue)  compared with $4.6 million (45% of revenue) in the comparable  quarter
of fiscal year 1995.  The decline in  production  costs as a percentage of total
revenues  reflect  the  company's  operating  leverage.  Production  costs  have
increased  in the quarter due to the higher  direct mail  marketing  sales which
have a lower gross margin than the Company's other products.

         Selling,  general and administrative expenses in the third quarter were
$5.2 million (43% of  revenue),  compared  with $4.8 million (47% of revenue) in
the  comparable  quarter of the prior  year.  The 10%  increase is due to higher
investment in sales resources.

         Research and development  costs decreased by $0.2 million compared with
the comparable  quarter of fiscal 1995 reflecting  reduced  outside  consultancy
costs  associated with the  development of Premiere.  The percentage of software
development costs capitalized has remained at similar rates in each period.

         Net  interest  expense  for the  quarter  ended March 31, 1996 was $0.4
million,  compared to $0.3  million for the  comparable  fiscal 1995  period,  a
result  of  reduced  levels of cash  following  the  consumption  of cash by the
discontinued operations.

         The  effective  tax rate for the  quarter  ended March 31, 1996 was 89%
which  compares  to a tax  provision  on a loss for the  comparable  fiscal 1995
period.  Excluding  the non-  continuing  debenture  interest  for  which no tax
benefit is obtained,  the effective rate was 56%. The rate differential reflects
the Company's higher  utilization during fiscal 1996 of net operating loss carry
forwards.


                    Nine Months Ended March 31, 1996 and 1995

         Revenue for the nine months ended March 31, 1996 was $34.2 million,  an
increase of 16% over the comparable period of the prior fiscal year. Eliminating
the impact of currency exchange rate  fluctuations,  revenues  increased by 15%.
The increase was principally due to 22% growth in PRECISE revenues.


                                       10

<PAGE>
         Production  costs for the nine  months  ended March 31, 1996 were $13.6
million (40% of revenue),  compared  with $13.0  million (44% of revenue) in the
comparable  fiscal  1995  period.  The  increase in costs was  primarily  due to
increased  revenues.  Production  costs  declined  as a  percentage  of  revenue
demonstrating the company's operating leverage.

         Selling,  general and administrative expenses for the nine months ended
March 31, 1996 were $15.5  million (45% of revenue)  compared with $14.4 million
(49% of  revenue)  for the  comparable  period of the  prior  fiscal  year.  The
increase in expenses was due to costs  associated  with the impending  launch of
Premiere,  including  $0.2 million of one time  promotional  costs and increased
investment in senior sales resources.

         Research and  development  costs were $2.6 million and $2.8 million for
each of the nine  months  ended  March  31,  1996 and  1995,  respectively.  The
decrease  for  fiscal  1996  reflects  lower  development  costs  for  Premiere,
principally reduced expenditure on software development consultants.

         Net interest  expense for the nine months ended March 31, 1996 was $1.1
million, unchanged from the comparable fiscal 1995 period.

         The effective tax rate for the nine months ended March 31, 1996 was 18%
which  compares  to a tax  provision  on a loss for the  comparable  fiscal 1995
period.  The lower  rate is due to tax  credits  in the first half of the fiscal
year  arising  from the  transfer of the PMSI  shares to the Source  business in
order to fund working capital.  Excluding debenture interest, the effective rate
would have been 8%. The rate  differential  reflects  changes in the anticipated
mix of profits of the Company's  subsidiaries  operating in different  countries
for the fiscal  year ending  June 30,  1996 plus the higher  utilization  of net
operating loss carry forwards in fiscal 1996.


                         Liquidity and Capital Resources


         At March 31, 1996, the Company's cash and cash equivalents totaled $4.5
million,  a decrease of $10.6 million from the $15.1 million balance at June 30,
1995.  The  decrease  is  primarily  due  to the  consummation  of  cash  by the
discontinued operations.

         The  consummation  of  the  initial  public  offering,   including  the
over-allotment,  resulted in the issuance of 3,186,091  shares of the  Company's
Common Stock and the generation of net proceeds of approximately  $34.8 million.
The Company has used  approximately  $14.2  million of the net proceeds to repay
its subordinated  debentures due March 31, 1997 and intends to use approximately
$0.5 million of the net proceeds to repay the remainder of those debentures. The
Company  anticipates  that the net proceeds from the initial public  offering of
its Common  Stock,  together  with  anticipated  cash flow from  operations  and
existing cash balances will satisfy the Company's  projected working capital and
capital expenditure requirements through at least the end of fiscal 1998.

                  MASTER REORGANIZATION  AGREEMENT,  dated as of April 16, 1996,
between WALSH INTERNATIONAL INC., a Delaware corporation  ("Walsh"),  and SOURCE
INFORMATICS INC., a Delaware corporation ("Source").

                  WHEREAS   Walsh,   through   various   direct   and   indirect
subsidiaries, operates in two business segments: (i) the "Walsh Business," which
includes sales force management and integrated  sales and marketing  information
services  for  the  pharmaceutical  industry,  associated  medical  professional
databases and other  services  related to those  databases,  such as direct mail
marketing and consulting, and (ii) the "Source Business," which includes a range
of products and services for such  industry,  primarily  marketed under the name
"Source,"  that  utilize  proprietary  databases of  prescriptions  dispensed by
retail outlets in the United States; and

                  WHEREAS the Board of  Directors  of Walsh has  determined,  in
light of the substantially  different  characteristics of the Walsh Business and
the Source Business,  the need of the Source Business for significant additional
investment in database  development  and certain other factors,  to separate the
Walsh and Source Businesses into two independent companies; and

                  WHEREAS a subsidiary of Walsh has recently formed
Source for the purpose of acting as the holding company for the
Source Business; and

                  WHEREAS on the Closing Date (as  hereinafter  defined),  Walsh
and certain of its subsidiaries  (the "Walsh  Subsidiaries")  will contribute to
Source  and  its  designated  subsidiaries  (the  "Source  Subsidiaries")  their
respective  ownership  interests  in the Source  Business,  those  being (i) the
assets and properties of Walsh and the Walsh  Subsidiaries  used  exclusively or
primarily in connection with the Source Business, subject to certain liabilities
and (ii) all of the  issued  and  outstanding  capital  stock of  certain  Walsh
Subsidiaries that are engaged in the Source Business (collectively,  the "Source
Assets")  in  return  for  shares of  preferred  and  common  stock of Source as
provided herein; and

                  WHEREAS Walsh intends to distribute the shares of common stock
of Source issued in exchange for the Source Assets to the common stockholders of
Walsh as provided herein; and

                  WHEREAS,  in  accordance  with  the  Restated  Certificate  of
Incorporation  of Walsh and  Section 1 of the  Agreement,  dated as of April 16,
1996,  by and among  Walsh,  Source and the holders of the Series A  Convertible
Preferred   Stock  of  Walsh  (the  "Walsh   Preferred   Stock")  named  therein
(individually,  a "Preferred  Stockholder,"  and  collectively,  the  "Preferred
Stockholders"),  the  Preferred  Stockholders  shall,  upon the Closing Date (as
hereinafter defined), exchange one-half of the aggregate number


<PAGE>



of shares  of Series A  Convertible  Preferred  Stock of Walsh  held by them for
shares of Series A Convertible Preferred Stock of Source; and

                  WHEREAS  Walsh has  agreed to  provide  Source  and the Source
Subsidiaries with certain professional management and technical support services
and  licenses to use certain  databases  and to  collaborate  with Source in the
development  of  their  respective  technologies,  all in  connection  with  the
operation  of the  Source  Business,  as such  support  services,  licenses  and
collaborative  efforts  shall  be  provided  for in  the  service,  license  and
technology agreements to be entered into pursuant to this Agreement; and

                  WHEREAS Walsh  proposes to issue to the public up to 3,277,500
shares of its Common Stock in an underwritten  public offering and, to that end,
has  filed a  Registration  Statement  on Form S-1  (No.  333-316)  (the  "Walsh
Registration Statement") with the Securities and Exchange Commission to register
such shares under the Securities Act of 1933, and the transactions  contemplated
hereby  are  to be  consummated  prior  to  the  effective  date  of  the  Walsh

                  SECTION 2.04.  Instruments of Conveyance and Transfer.  On the

<PAGE>
pursuant to this Agreement,  (iii) certificates evidencing any shares of capital
stock to be  transferred  to such Source  Entity  hereunder,  duly  endorsed for
transfer  to  such  Source  Entity  as  provided  in  Section  2.01  hereof,  or
accompanied by stock transfer powers duly endorsed in blank,  with all requisite
stock transfer taxes paid and stamps affixed, and (iv) such other bills of sale,
instruments of assignment and other  appropriate  documents as may be reasonably
necessary in order to carry out the  intentions  and purposes of Section 2.01 of
this Agreement.

                  SECTION  2.05.  Assumption  of  Liabilities.  Subject  to  the
conditions  hereinafter set forth,  on the Closing Date,  Source shall, or shall
cause each Source Entity  acquiring  any Source Assets  hereunder to execute and
deliver to the Walsh Entity whose name appears  opposite  such source  entity on
Schedule 2.01 hereof an undertaking,  in form satisfactory to Walsh, pursuant to
which such Source  Entity shall assume and agree to pay,  perform and  discharge
when due the  liabilities  and  obligations  of such Walsh Entity related to the
Source  Assets  being  transferred,  and other  appropriate  documents as may be
reasonably necessary to carry out the intentions and purposes of Section 2.01 of
this Agreement.

                  SECTION 2.06.  Non-Assumption of Certain Liabilities.  Neither
Source  nor any  Source  Subsidiary  is  assuming,  nor  shall be deemed to have
assumed,  any liabilities or obligations of Walsh or of any Walsh  Subsidiary of
any kind or nature  whatsoever,  except (i) to the extent  such  liabilities  or
obligations  are  liabilities or obligations of the Source  Business and (ii) as
expressly provided above in Section 2.05 hereof.

                  SECTION 2.07.  Nonassignable  Contracts.  Walsh shall promptly
apply  for  or  otherwise  seek  and  use  reasonable   efforts  to  obtain  all
authorizations, consents, waivers and approvals as may be required in connection
with the assignment of the leases, agreements, contracts, commitments, licenses,
permits,  service  marks and other  rights to be assigned  hereunder,  and shall
provide  Source with copies of all such  authorizations,  consents,  waivers and
approvals  promptly  after  they  have been  obtained.  To the  extent  that the
assignment  of any lease or other right  shall  require the consent of any other
party thereto,  this  Agreement  shall not constitute an agreement to assign the
same if an attempted  assignment would constitute a breach thereof. In the event
that any  lease  or  other  right,  property  or  asset  of  Walsh or any  Walsh
Subsidiary  cannot be effectively  transferred to Source or a Source  Subsidiary
without the consent of a third party,  and if on the Closing Date Walsh does not
receive  such  consent,  Walsh shall  thereafter  be  obligated  to use its best

         hereunder.

                  SECTION  6.02.  Stockholder  Approval;  Third-Party  Consents.
Promptly after the date hereof, Walsh shall take all steps necessary in order to
obtain approval by the stockholders of Walsh of the transactions contemplated by
this  Agreement.  In  addition,   Walsh  shall,  with  Source's  assistance  and
cooperation,  promptly apply for or otherwise  seek and use its reasonable  best
efforts to obtain all authorizations,  consents, waivers and approvals as may be
required  in  connection  with  the  assignment  of the  contracts,  agreements,
licenses,  leases,  sales orders,  purchase  orders and other  commitments to be
assigned to Source or any Source Subsidiary pursuant hereto, provided that Walsh
shall not be required to institute litigation or pay additional consideration to
a third party for such  purpose.  Source agrees that at all times after the date
hereof and prior to the Closing Date it will cooperate with Walsh in its efforts
to obtain such authorizations, consents, waivers and approvals.

                  SECTION 6.03.  Transferred  Assets.  Walsh and Source covenant
and  agree to use  their  best  efforts  to obtain  any  requisite  governmental
approvals for the  acquisition  of the Source Assets by Source and/or any Source
Subsidiary.  In the event that Source has not  received  on the  Closing  Date a
requisite  approval of any governmental  entity to permit purchase of any Source
Assets or the  transfer of any  component  of the Source  Business at such time,
Walsh or the Walsh  Subsidiary,  as the case may be, shall continue,  consistent
with  applicable  law, to hold such Source Assets or operate the Source Business
component,  as the case may be, for the  account of Source  until such  approval
shall have been received,  at which time Walsh or the Walsh  Subsidiary,  as the
case  may be,  shall  transfer  such  Source  Assets  to  Source  or the  Source
Subsidiary  promptly with the appropriate  documentation  as required by Section
2.04  hereof.  For  purposes of this  Agreement,  "operate  the Source  Business
component"  shall mean that Walsh or the Walsh  Subsidiary,  as the case may be,
shall  respond  to the  direction  of  Source in the  daily  operations  of such
component  insofar as consistent  with  applicable  law, but Walsh or such Walsh
Subsidiary  shall not be liable for loss of profits or other claims  relating to
the  conduct of the  business of such  component  except such as result from the
gross negligence or wilful misconduct of Walsh or such Walsh Subsidiary.  In the
event that Source is unable to obtain a required  approval to acquire any Source
Assets,  the  parties  agree to  cooperate  and to use  their  best  efforts  to
restructure  the  transaction so as to obtain such approval or  restructure  the
transaction so as not to require such approval,  in either case  consistent with
applicable law.

covenant  and  agree  with the  other to  provide  to the  other  all  financial
information,  reports and other data relating to the Source Business required by
the  requesting  party in satisfying its reporting  obligations to  governmental
agencies and in completing its tax and other governmental returns.

                  SECTION  6.05.  Confidentiality.  Walsh  shall not at any time
after  the date  hereof  divulge,  furnish  or make  accessible  to  anyone  any
knowledge or  information  with  respect to  confidential  or secret  processes,
inventions,  discoveries,  improvements,  formulae, plans, material,  devices or
ideas or know-how,  whether  patentable or not,  relating to any confidential or
secret  aspects of the Source  Business;  provided,  however,  that (i)  nothing
herein shall prohibit Walsh from complying with any order or decree of any court
of competent  jurisdiction  or  governmental  authority  and (ii) the  foregoing

available to the public through no breach of this Agreement.

                  SECTION 6.06. Transferred Employees. (a) Source agrees that it
will offer each employee of Walsh or any Walsh Subsidiary identified by Walsh as
being  employed  in the  conduct  of the Source  Business  the  opportunity  for
employment  as  employees  of  Source  or a Source  Subsidiary  (with  terms and
conditions of employment and benefits  substantially similar to those previously
in effect  while such  employee  was  employed by Walsh or any Walsh  Subsidiary
unless  otherwise  agreed)  effective on the Closing Date,  it being  understood
that, except as provided in any existing employment  agreements or by applicable
law, such employment shall be employment at will.

                  (b) Walsh  employees who accept  employment  offered by Source
(collectively,  the "Transferred Employees") and who are actively at work on the
day prior to the  Closing  Date  shall  become  employees  of Source or a Source
Subsidiary  on the Closing Date.  Transferred  Employees who are not actively at
work on the day prior to the Closing  Date shall  become  employees of Source on

Transferred  Employee  to, the number of  vacation  and sick leave days that the
Transferred  Employee was credited with on the day prior to employment by Source
or a Source Subsidiary.  In addition,  on the day a Transferred Employee becomes
an employee of Source, the Transferred  Employee will be credited with all years
of service that the  Transferred  Employee  was  credited  with at Walsh for the
purposes of determining eligibility to participate in any of Source's employee

benefit  plans,  benefits  and  services,  as  well as for  the  application  of
policies, practices and procedures, including, but not limited to, seniority for
layoff,  sick leave,  service awards,  severance pay and vacation accrual.  Each
Transferred  Employee  shall be eligible  to  participate  in  Source's  medical
benefit  plans on the date he or she  becomes an employee of Source or in a plan
or plans  substantially  similar to the plans of Walsh  effective on the Closing
Date.

                  SECTION 6.07. Stock Options and Warrants. (a) On and after the
Closing Date,  employment or termination of employment with Source or any Source
Subsidiary,  as the case may be, shall be deemed  employment or  termination  of
employment,  as the case may be, with Walsh or any Walsh Subsidiary for purposes
of the vesting and termination provisions of the Walsh stock options held by the
Transferred  Employees.  All unvested  Walsh stock  options held by  Transferred
Employees  as of the Closing  Date shall  continue to vest and all vested  Walsh
stock  options  held by  Transferred  Employees  as of such  date  shall  remain
exercisable  all in  accordance  with the  terms  of the  related  stock  option
agreements.

                  (b) Source shall grant to each  employee of Walsh or any Walsh
Subsidiary (whether or not such employee becomes a Transferred Employee) holding
a Walsh stock  option as of the  Closing  Date a stock  option to  purchase  the
number of shares of Source  Common Stock  representing  the same  percentage  of
Source's  fully-diluted equity as the percentage of Walsh's fully-diluted equity
represented by the Walsh stock options held by such  employee.  Each such Source
stock option shall vest in accordance  with same vesting  schedule set forth in,
and the same percentage of shares shall be deemed vested as of the date of grant
as have vested under, the Walsh stock option held by the employee.

                  (c) Source  shall grant to each holder of Walsh's  outstanding
stock purchase  warrants as of the Closing Date a warrant to purchase the number
of shares of Source Common Stock  representing  the same  percentage of Source's
fully  diluted  equity  as  the  percentage  of  Walsh's   fully-diluted  equity
represented by the Walsh stock purchase warrant held by such holder.

                  (d) The aggregate  exercise  price of each  outstanding  Walsh
option or warrant in respect of which a Source option or warrant shall be issued
by Source  pursuant to this Section 6.07 shall be  allocated,  as of the Closing
Date,  between such Walsh option or warrant and the Source  option or warrant so
issued in  proportion  to the  relative  fair market  values of the Walsh Common
Stock and the Common  Stock of Source as of such date.  The fair market value of
the Walsh Common Stock shall be equal to its initial  public  offering  price in
the Walsh underwritten public


                                       17

<PAGE>
offering  and the  fair  market  value  of the  Source  Common  Stock  shall  be
determined in good faith by the Board of Directors of Source.

                  (e) The  issuance  of stock  options  and  warrants  by source
pursuant to this Section 6.07 shall be subject to any necessary  compliance with
Federal securities laws and state "blue sky" securities laws.

                  SECTION  6.08.  Further  Assurances.  (a) At any time and from
time to time on and after the  Closing  Date,  Walsh  shall,  at the  request of
Source,  execute and deliver or cause to be executed and delivered to Source all
such deeds, assignments, consents, documents and further instruments of transfer
and conveyance,  and take or cause to be taken all such other actions, as Source
may  reasonably  deem  necessary or desirable in order to fully and  effectively
vest in Source or any Source  Subsidiary,  as the case may be, or to confirm its
title to and possession of, the Source Assets, or to assist Source in exercising
rights with respect thereto which Source is entitled to exercise pursuant to the
terms of this  Agreement;  and Source  shall  execute and deliver or cause to be
executed and delivered  such further  instruments  and take or cause to be taken
such  further  actions as Walsh may  reasonably  deem  necessary or desirable to
carry out the terms and provisions of this Agreement.

                  (b) In the event that Source shall determine at any time after
the  Closing  Date that it has not  acquired  hereunder  any  properties  or any
authorizations,  licenses  or  other  rights,  or  any  services  or  facilities
necessary to the conduct of the Source Business, Walsh shall, to the extent such
assets or rights are  unavailable  to Source  from third  parties on  reasonable
terms and to the extent  Walsh is capable of doing so,  negotiate  in good faith
with Source to provide Source with such assets or rights on terms  comparable to
those on which Walsh has agreed to provide  similar  assets or rights  under the
Additional Agreements.

                  SECTION 6.09. Inspection and Preservation of Records, Etc. (a)
On and after the Closing Date,  each party hereto upon request will permit,  and
Source will cause each Source Subsidiary to permit,  the other party hereto, its
representatives  and any firm designated by such requesting  party to act as its
independent public  accountants,  at all reasonable times during business hours,
to  inspect  the files,  books,  records  and  accounts  of the Source  Business
reflecting  transactions through the Closing Date or relating to transactions as
to which  Walsh or any  Walsh  Subsidiary  shall  continue  to have  primary  or
contingent  liability after the Closing Date and will give such requesting party
and such accountants access to all accounting and other records and documents of
the Source Business to enable such accountants to


                                       18

<PAGE>
conduct any audit or any other  procedures  which such requesting  party or such
accountants  may deem necessary in connection  with the  preparation,  review or
audit of any financial  statements or tax returns of such requesting party or to
comply with any other request of a  governmental  entity.  The party holding the
records being inspected will render,  at the requesting  party's  expense,  such
assistance  as  the  requesting  party  and  such  accountants  may  request  in
completing any of the foregoing  determinations or such other reviews, audits or
procedures or in complying with any government request.

                  (b) On and after the Closing Date, each party will permit, and
Source will cause each Source Subsidiary to permit,  the other party hereto, its
representatives  and its counsel,  at reasonable times during business hours, to
inspect all the files,  books,  records and accounts of the Source Business held
by a party or such Source  Subsidiary,  as well as access to any employee of the
Source  Business  or former  employee of the Source  Business  employed by Walsh
having knowledge of the information  therein  contained,  if such inspection and
access are reasonably  necessary for the defense by such requesting party of any
litigation relating to the Source Business prior to the Closing Date or relating
to transactions as to which Walsh or any Walsh Subsidiary shall continue to have
primary or contingent liability after the Closing Date.

                  (c) For a period of six years  after the  Closing  Date,  each
party shall preserve the business  records of the Source Business owned by them,
shall allow the other party hereto and its representatives  reasonable access to
such  records  and the  right  to make  copies  and  extracts  therefrom  at any
reasonable  time  during  normal  business  hours,  and shall not dispose of any
thereof,  provided that,  commencing three years after the Closing Date, a party
may give the other party written  notice of its intention to dispose of any part
thereof,  specifying the items to be disposed of in reasonable detail. Any party
may,  within a period of 60 days from  receipt  of any such  notice,  notify the
disposing  party of its desire to retain one or more of the items to be disposed
of. The  disposing  party shall,  upon  receipt of such  notice,  deliver to the
requesting party, at its expense, the items specified therein.

obligations of the Source  Business,  including  those assumed by Source or such
Source  Subsidiary  pursuant  to this  Agreement,  or (iii) any action  made out
against  Walsh or any Walsh  Subsidiary  that arises out of or results  from the
operation of the Source  Business,  whether arising with respect to transactions
or events occurring prior to or after the Closing Date; provided,  however, that

indemnifying  party shall have the right to  undertake  the  defense  thereof by
representatives of its own choosing.

after  receipt  of notice of any such claim (or,  if  earlier,  by the tenth day
preceding  the day on which an answer or other  pleading must be served in order

does not elect to defend against such claim,  the party to be  indemnified  will
(upon further notice to the indemnifying  party) have the right to undertake the
defense, compromise or settlement of such claim on behalf of and for the account
and risk of the  indemnifying  party,  subject to the right of the  indemnifying
party to assume  the  defense  of such  claim at any time  prior to  settlement,
compromise or final determination thereof.

                  (c)   Anything   in  this   Section   8.04  to  the   contrary
notwithstanding,  (i) if  there is a  reasonable  probability  that a claim  may
materially and adversely affect the indemnifying party other than as a result of
money damages or other money  payments,  the  indemnifying  party shall have the
right, at its own cost and expense, to compromise or settle such claim, but (ii)
the indemnifying party shall not, without the prior written consent of the


                                       24

<PAGE>
party to be indemnified,  settle or compromise any claim or consent to the entry
of any  judgment  that does not  include as an  unconditional  term  thereof the
giving by the claimant or the plaintiff to the party to be indemnified a release
from all liability in respect of such claim.

                  (d)  In  connection   with  any  such   indemnification,   the
indemnified party will cooperate in all reasonable  requests of the indemnifying
party.

                  SECTION 8.05. Remedies Cumulative.  Except as herein provided,
the  remedies  provided  herein  shall be  cumulative  and  shall  not  preclude
assertion  by any party  hereto of any other  rights or the seeking of any other
remedies against the other party hereto.

                               SERVICES AGREEMENT



                  THIS  AGREEMENT,  dated as of April 16,  1996,  between  WALSH
INTERNATIONAL  INC., a Delaware  corporation  ("Walsh")  and SOURCE  INFORMATICS
INC., a Delaware corporation ("Source").

                  WHEREAS,  pursuant  to the  Master  Reorganization  Agreement,
dated as of the date hereof (the "Master Agreement"),  between Walsh and Source,
Walsh has agreed to  transfer  to Source  certain of  Walsh's  assets  including

dispensed in the United States and other  counties,  and are designed to be used
by  the  pharmaceutical   industry  in  sales  force   compensation,   territory
realignment and focused promotion (the "Source Business"); and

                  WHEREAS,  in  spite  of the  formation  of a  Source  business
distinct from Walsh and Source having its own management and professional staff,
Source  nevertheless  wishes to avail itself,  during a transition  period after
consummation of the transfer to it of the Source Business, of the experience and
expertise of certain  Management,  financial and professional Walsh personnel to
assure  continuity in its business  operations and to facilitate  further growth
and development; and

                  WHEREAS,  Walsh is willing to make available to Source and its
subsidiaries  the services of certain  management,  financial  and  professional
personnel to provide  required support  services  required by Source,  under the
following terms and conditions.

                  initial period of 24 months with respect to general management
                  services,  and a period  of not  more  than  six  months  with
                  respect to financial and legal services and, Walsh shall,  and
                  shall  cause  its  subsidiaries  to  provide,   the  following
                  employees  to  Source  and its  subsidiaries,  on a  part-time
                  basis, to provide management and function- al support services
                  specified below:

                  (i)      General Management Services -- Michael A. Hauck


<PAGE>

                  (iii)    Legal Services -- Leonard R. Benjamin

                  (iv)     Any other executives of Walsh or its subsidiaries who
                           are  deemed  by the  individuals  named  above  to be
                           necessary or appropriate to provide,  or to assist in
                           providing, management,  financial, and legal services
                           hereunder.

         (b)      Notwithstanding   anything  herein  to  the  contrary,  it  is
                  understood that the  individuals  identified in Paragraph 1(a)
                  hereof  shall  devote at least 80% of their  business  time to

         (c)      In  the  event  that  any  of the  individuals  identified  in
                  Paragraph 1(a) hereof is unable to provide the services in the
                  areas described above,  Walsh shall provide other individuals,
                  acceptable to Source, to perform the specified services.

         (d)      In consideration  for the services  provided by Walsh pursuant
                  to Paragraph 1(a),  Source shall pay to Walsh a fee calculated

                  time  spent on  Source  activi-  ties and the  details  of the
                  remuneration  (and other related costs)  attributable  to said
                  Walsh  personnel for the purposes of verifying the fee payable
                  by  Source  to  Walsh.  The fee  shall be  payable  by  Source
                  quarterly on the last day of April,  July, October and January
                  of each year.

2.       TERM OF AGREEMENT AND TERMINATION

         (a)      This  Agreement  shall  commence  with the  Closing  and shall
                  continue for a period of 24 months. Thereafter, this Agreement
                  shall  automatically  be renewed  for  successive  three month
                  periods unless either Walsh or Source notifies the other party
                  in writing of its  intention to terminate  the  Agreement,  or
                  specific  services  provided  pursuant  thereto,  at least one
                  month prior to the beginning of the applicable renewal period.

         (b)      Either  Walsh or Source may  terminate  this  Agreement if the
                  other has  defaulted in any material  obligation  hereunder by
                  giving  at least  30 days,  written  notice  to the  breaching
                  party; provided, however, that if the


                                        2

<PAGE>
                  breaching  party  corrects  such  default  within  said 30 day
                  period,  this  Agreement  shall  continue  in full  force  and
                  effect.

         (c)      Either  Walsh  or  Source  may  terminate  this  Agreement  by
                  immediate written notice if the other party becomes insolvent,
                  or a court of competent jurisdiction enters an order or decree
                  in respect of such party under any  bankruptcy or similar law,
                  approving  a  petition  for  reorganization  or  appointing  a
                  custodian  for  all or a  substantial  part of its  assets  or
                  ordering the liquida- tion of such party.

3.       EXPENSES

         Source shall reimburse Walsh for all reasonable travel,  accommodation,
         living and  entertainment  expenses  actually  incurred by Walsh or its
         subsidiaries  in  providing  any  of the  services  specified  in  this
         Agreement.

4.       CONFIDENTIALITY

         For the purposes of enabling Walsh to perform the services  required by
         this Agreement,  Source shall grant Walsh access to Source's  premises,
         files and staff and shall fully disclose to Walsh all  confidential and
         proprietary  information necessary to enable Walsh and its subsidiaries
         to provide the services  hereunder.  In addition to any covenants  with
         respect to  confidentiality  contained in the Master  Agreement,  Walsh
         agrees  that it shall,  and cause its  subsidiaries  to,  maintain  the
         confidentiality,  and neither disclose to third parties nor use for its
         own purposes  (except as separately  agreed),  all such  information so
         disclosed  to  it;   provided,   however,   that  the   obligation   of
         confidentiality  specified  above shall not extend to: (i)  information
         that is or subsequently  becomes public  knowledge  through no fault of
         Walsh or any other Walsh subsidiary;  or to (ii) information that comes
         into the possession of Walsh or a Walsh  subsidiary  from a third party
         not under an obligation of confidentiality to Source.

5.       LIABILITY OF WALSH

         (a)      This  Agreement  constitutes  a contract for the  provision by
                  Walsh  of  services  as an  independent  contractor  and not a
                  contract  of  employment.  Accordingly,  Walsh  shall  pay all
                  salaries and other  compensation  due to employees of Walsh or
                  any  Walsh  subsidiary  engaged  in  the  performance  of  the
                  services  specified herein.  Walsh shall withhold,  deduct and
                  remit all taxes, contributions or imposts


                                        3

<PAGE>
                  required  by  any  Government  having  jurisdiction  over  the
                  relationship between Walsh employees and Walsh.

         (b)      Walsh  agrees to use its best efforts to render the ser- vices
                  required of it  hereunder  in a diligent  and  profes-  sional
                  manner.

         (c)      Walsh's liability,  however, for wrongful acts or omissions in
                  breach of this Agreement  shall not extend to damages for lost
                  profits or other consequential damages.

6.       MISCELLANEOUS PROVISIONS

         (a)      This Agreement shall not be assignable by either party without
                  the  prior  written   consent  of  the  other,   except  to  a
                  wholly-owned subsidiary of either Walsh or Source, as the case
                  may be. In the event of a permitted  assignment,  however, the
                  assigning  party shall  guarantee the  performance  of all the
                  obligations under this Agreement.

         (b)      No waiver, modification or alteration of any of the provisions
                  of this Agreement  shall be binding unless approved in writing

         (c)      This Agreement  embodies the entire  contractual  relationship
                  between the parties in relation to the subject  matter hereof,
                  and no other agreement or understanding,  verbal or otherwise,
                  exists between the parties at the time of execution hereof.

                  writing and  personally  delivered or mailed by  registered or
                  certified  mail,  return receipt  requested,  or  telegraphed,

                  WHEREAS,  in  spite  of the  formation  of a  Source  business
distinct from Walsh and Source having its own management and professional staff,
Walsh  nevertheless  wishes to avail  itself,  during a transition  period after
consummation of the transfer to Source of the Source Business, of the support of

continuity on Walsh's business operations; and
                  WHEREAS,  Source is  willing  to make  available  to Walsh the
functional  support  services  required by Walsh or its  subsidiaries  under the
following terms and conditions.




<PAGE>
                  NOW, THEREFORE, in view of the premises stated above and
of the mutual covenants and agreements hereinafter set forth, the
parties hereto agree as follows:

1.       SERVICES
         
         (a)      Commencing   with  the   Closing   (the   "Closing")   of  the

 (i)     Executive Services;

                  (ii)     Human Resources Services;

                  (iii)    Financial Services; and

                  (iv)     Any other functional support and consulting  services
                           of Source  which are deemed by Walsh to be  necessary
                           or appropriate to reasonably assure continuity in its

                  continue for a period of 24 months. Thereafter, this Agreement
                  shall  automatically  be renewed  for  successive  three-month
                  periods unless either Walsh or Source notifies the other party

                  immediate written notice of the other party becomes insolvent,
                  or a court of competent jurisdiction enters an order or decree
                  in respect of such party under any  bankruptcy or similar law,
                  approving  a  petition  for  reorganization  or  appointing  a
                  custodian  for  all or a  substantial  part of its  assets  or
                  ordering the liquida- tion of such party.

3.       EXPENSES
         
         Walsh shall reimburse Source for all reasonable travel,  accommodation,
         living and  entertainment  expenses actually incurred by the Source and
         its  subsidiaries  in providing  any of the services  specified in this
         Agreement.

4.       CONFIDENTIALITY
         
         For the purpose of enabling the Source to perform the services required
         by this Agreement, Walsh shall grant Source access to Walsh's premises,
         files and staff and shall fully disclose to the Source all confidential
         and  proprietary   information  necessary  to  enable  Source  and  its
         subsidiaries  to provide  the  services  hereunder.  In addition to any
         covenants  with  respect  to  confidentiality  contained  in the Master
         Agreement,   Source   agrees  that  it  shall,   and  shall  cause  its
         subsidiaries to,


                                        4


<PAGE>
         maintain the confidentiality, and neither disclose to third parties nor
         use for its own  purposes  (except  as  separately  agreed),  all  such
         information so disclosed to it; provided,  however, that the obligation
         of confidentiality specified above shall not extend to: (i) information
         that is or subsequently  becomes public  knowledge  through no fault of
         the Source Group; or to (ii) information that comes into the possession
         of the  Source  Group  from a third  party not under an  obligation  of
         confidentiality to Walsh or any of its subsidiaries.

5.       LIABILITY OF SOURCE
  
         (a)      This  Agreement  constitutes  a contract for the  provision by
                  Source of  services  as an  independent  contractor  and not a
                  contract  of  employment.  Accordingly,  Source  shall pay all
                  salaries  and other  compensation  due to  employees of Source
                  engaged in the performance of the services  specified  herein.
                  Source   shall   withhold,   deduct   and  remit  all   taxes,
                  contributions  or imposts  required by any  Government  having
                  jurisdiction  over the  relationship  between Source employees
                  and Source.

         (b)      Source  shall  use its best  efforts  to render  the  services
                  required  of  it  hereunder  in a  diligent  and  professional
                  manner.

<PAGE>

         (c)      Source's liability, however, for wrongful acts or omissions in
                  breach of this Agreement  shall not extend to damages for lost
                  profits or other consequential damages.

6.       MISCELLANEOUS PROVISIONS
         
         (a)      This Agreement shall not be assignable by either party without
                  the  prior  written   consent  of  the  other,   except  to  a
                  wholly-owned subsidiary of either Walsh or Source, as the case
                  may be. In the event of a permitted  assignment,  however, the
                  assigning  party shall  guarantee the  performance  of all the
                  obligations under this Agreement.

         (b)      No waiver, modification or alteration of any of the provisions
                  of this Agreement  shall be binding unless approved in writing
                  by duly authorized representatives of the parties.

         (c)      This Agreement  embodies the entire  contractual  relationship
                  between the parties in relation to the subject  matter hereof,
                  and no other agreement or understanding,  verbal or otherwise,
                  exists between the parties at the time of execution hereof.

                  and may be personally  delivered or delivered by registered or

                     PREFERRED TECHNOLOGY PARTNER AGREEMENT


         PREFERRED  TECHNOLOGY  PARTNER  AGREEMENT,  dated as of April 16, 1996,
between WALSH INTERNATIONAL INC., a Delaware corporation  ("Walsh"),  and SOURCE
INFORMATICS INC., a Delaware corporation ("Source").

         WHEREAS  Walsh is engaged in the  business  of  providing  sales  force
management and integrated sales and marketing information  services,  associated
medical professional  databases and other services related to those databases to
and on behalf of the pharmaceutical industry (the "Walsh Business"); and

         WHEREAS, pursuant to the Master Reorganization  Agreement,  dated as of
the date hereof (the "Master  Agreement"),  between Walsh and Source,  Walsh has
agreed to transfer to Source  certain of Walsh's  assets  including its products
and services that are based on proprietary databases of prescriptions  dispensed
in the  United  States and in other  countries  and  designed  to be used by the
pharmaceutical  industry in sales force compensation,  territory realignment and
focused promotion (the "Source Business"); and

         WHEREAS, in view of the complementary  nature of the Walsh Business and
the Source  Business,  the  parties  have  decided  to enter into a  development
project in order to facilitate the delivery of Source  prescription  data to its
(Source) clients utilizing Walsh technology services.

         NOW,  THEREFORE,  in  consideration  of the  premises  and  the  mutual
covenants herein contained, the parties agree as follows:


                                    ARTICLE I

                            AGREEMENT TO COLLABORATE

         Section 1.01. Development and Maintenance of Data Interface.  Walsh and
Source hereby agree to collaborate on the creation,  maintenance,  modification,
updating  (including  routine  updating  of the  databases  and the  information
contained therein), revising, enhancing and testing of a computer interface (the
"Interface")  between their respective  technologies  enabling  Source's data on
prescriptions  dispensed in the United States and any other  jurisdiction  where
Source  provides  such  data  ("Prescription  Data") to be  delivered  by Source
directly to its client through Walsh  technology  services,  minimizing the need
for reprocessing.

<PAGE>

         Section  1.02.  Promotion of  Interface.  Walsh and Source hereby agree
that each of them and any of their respective  subsidiaries shall have the right
to  promote  the  Interface  between  their   technologies  in  marketing  their

wherever Source provides  Prescription  Data.  Such  promotional  activities may
include any activities and decision-making  related to the  commercialization of
products and services included in the Walsh Business or the Source Business that
utilize  the  Interface  including,   without  limitation,  all  activities  and
decision-making   relating  to   marketing,   pricing,   product   strategy  and
positioning,  detailing,  sale, delivery,  servicing, and training in the use of
such products and services.


                                   ARTICLE II

responsibility of the respective party.

recommended or plans to overcome such anticipated or potential difficulties.

         (c) Such final report shall include a summary of the entire performance
hereunder.

                                 CONFIDENTIALITY

         Section  3.01.  (a)  In  addition  to any  covenants  with  respect  to
confidentiality  contained  in the  Master  Agreement,  during  the term of this
Agreement and for a period of five years thereafter,  neither party shall reveal
or  disclose  to  third  parties,  nor use  for  any  purposes  other  than  the
fulfillment of this Agreement,  any confidential  information  received from the
other party in  connection  with this  Agreement  without  first  obtaining  the
written  consent of such party.  This  obligation of  confidentiality  shall not
apply to any  information  that (i) is or becomes a matter of public  knowledge,
(ii) is already in the  possession of the  recipient,  (iii) is disclosed to the
recipient  by a third party  having the right to do so, (iv) is in response to a
valid order of a court or other governmental body to which a party hereto may be
subject or otherwise  required by law;  provided,  however,  that in the case of
disclosure by the receiving party  hereunder,  such party shall first have given
as much notice to the  disclosing  party as  practical,  or (v) is  necessary to
establish patent rights,  copyrights or other intellectual property rights which
are capable of being registered, but only after receiving the written consent of
the disclosing party, which consent shall not be unreasonably withheld.

         (b)  The  promotion  of  the  Interface  which   inherently   discloses
confidential information of either party shall not in itself be prohibited.

         (c) All information  supplied by either party hereto in connection with
the development of the Interface shall be treated as confidential information of
the party so supplying such information. Information developed during the course
of the development of the Interface and in connection therewith shall be treated
as the confidential information of both parties.

         (d)  Notwithstanding  any  other  provision  of this  Article  III,  no
copyright  license is granted in this  Article III by either  party to the other
with  respect to (i) any program code or microcode or (ii) any document or other
media  containing a notice of copyright which may be included in the information
exchanged hereunder.

         (e) No  public  announcement  or  other  disclosure  to  third  parties
concerning the existence of or the terms of this Agreement shall be made, either
directly or indirectly, by any party to this Agreement, except as may be legally
required,  without first obtaining the approval of the other party and agreement
upon the nature and text of such announcement or disclosure.

         Section 4.01. (a) The copyrights and other intellectual property rights
in the Interface,  and any related documentation or information containing media
developed under this Agreement (hereinafter "Work Product") shall be jointly and
equally  owned  and,   subject  to  Article  III,  each  party  shall  have  the
unrestricted right to grant licenses (including the right for any sublicensee to
grant  sublicenses)  to a third party  thereunder  without  accounting  and with
necessary  consent  hereby  given to the other  party as may be  required by any
country law in granting  such  licenses to a third  party.  Notwithstanding  the
foregoing,  neither party may use the Interface in connection  with the products
or services that compete with products or services of the other party.

         (b) Each party  shall have the right to obtain and to hold in the joint
owners' name copyrights,  registrations  and such other statutory and common law
protection as may be available,  and any extensions and renewals thereof, in the
Work  Product  referred to in this  Article IV in which it has joint  ownership.
Each party  agrees to give the other  party,  and any person  designated  by the
other party, at such other party's expense,  all assistance  reasonably required
to perfect the rights defined in this Article IV.

         (c)  Subject to Article  III,  to the extent  that any  pre-exist-  ing
materials,  other than program code or microcode,  of one party are contained in
the Work Product which is owned solely or jointly by the other party,  the party
providing the  pre-existing  materials  agrees to grant and hereby grants to the
owner of the Work Product a  non-exclusive,  worldwide,  and, subject to Section
2.06 hereto,  fully paid-up right and license under  copyright to use,  execute,
reproduce,  display, perform, distribute copies of, and prepare derivative works
of, such pre-existing materials, and to authorize others to do any, some, or all
of the foregoing.

         (d) Notwithstanding  any other provision of this Agreement,  no program
code or  microcode  is licensed  under this  Agreement.  The notice of copyright

interfere or be  inconsistent  with the activities to be undertaken  pursuant to
this Agreement.

that,  regarding any  information  to be disclosed to the other party under this
Agreement,  it has or will have the full  right and power to  disclose  same and
that the use of any such  information  by the other party will not  constitute a
misuse or misappropriation of any trade secret or any other type of confidential
information of any third party.

         Section 5.03. No Liability.  Neither party shall be liable to the other
party for any lost revenue, lost profits or other consequential damages, even if
advised of the possibility of such damages, which may result from its failure to
perform its  obligations  under this Agreement and neither party shall be liable
for any claim against the other party by any third party.  Notwithstanding  this
limitation  of liability  clause,  nothing in this  Agreement  will limit either
party's payment obligations hereunder.


                                   ARTICLE VI

hereto.

         Section 6.02.  Termination.  Either party may terminate  this Agreement
(a) by immediate written notice if the other party hereto becomes insolvent,  or
if a court of  competent  jurisdiction  enters an order or decree in  respect of
such company  under any  bankruptcy  or similar law, or approving a petition for
reorganization  or appointing a custodian  for all or a substantial  part of its
assets or  ordering  liquidation  of such  company or (b) if the other party has
defaulted  in any  material  obligation  hereunder  by  giving at least 30 days'
written notice to the breaching party; provided,  however, that if the breaching
party  corrects such default  within said 30 day period,  this  Agreement  shall
continue in full force and effect.

         Section  6.03.   Effect  of  Termination.   Upon  termination  of  this
Agreement,  the  obligations  to make payments in  accordance  with Section 2.07
hereof and the  obligations  of  confidentiality  specified in Article III shall
nevertheless survive. Upon termina- tion, however,  Walsh or Source, as the case
may be, shall return to

         Section 7.01.  Relationship  of the Parties.  Nothing in this Agreement
shall  constitute  or be deemed to  constitute  (a) a  partnership  between  the

consent of the
other.

         Section  7.02.  No  Default.  No party shall be  considered  in default

         Section 7.03. Assignability.  This Agreement shall not be assignable by

                           PHARBASE LICENSE AGREEMENT


                  THIS  AGREEMENT,  dated as of April 16,  1996,  by and between
WALSH INTERNATIONAL INC., a corporation organized under the laws of the State of
Delaware  (hereinafter  "WALSH"),  and SOURCE  INFORMATICS  INC., a  corporation
organized under the laws of the State of Delaware (hereinafter "SOURCE").

                                   WITNESSETH:

                  WHEREAS, WALSH has developed Medical Professional
Databases containing detailed demographic information about
physicians; and
                  WHEREAS, WALSH has licensed its Medical Professional Databases
(the "Pharbase  Databases") to pharmaceutical  companies in certain countries to
help them identify, and promote to, specific doctors or groups of doctors within
the total doctor population; and

                  WHEREAS,  pursuant  to the  Master  Reorganization  Agreement,
dated as of April 16, 1996 (the "Master  Agreement"),  between WALSH and SOURCE,
WALSH has agreed to  transfer to SOURCE or its  subsidiaries  certain of WALSH's
assets  including  its  products  and  services  that are  based on  proprietary
databases  of  prescriptions  dispensed  in  the  United  States  and  in  other
countries, and designed to be used by the pharmaceutical industry in sales force
compensation,  territory  alignment  and  focused  promotion  (SOURCE  and  such
subsidiaries being hereinafter referred to collectively as the "SOURCE Group");

         WHEREAS,   the  SOURCE  Group   intends  to  provide   physician-linked
prescription database services to pharmaceutical and

<PAGE>
healthcare companies operating in the United Kingdom, France, Germany,  Belgium,
The Netherlands, Spain and Italy; and

                  WHEREAS, WALSH is willing to license the Pharbase Databases to
the SOURCE Group for use internally in the  development  and  maintenance of the
SOURCE Group's SOURCE prescription database products and related services; and

                  WHEREAS,  SOURCE is  interested  in becoming a licensee of the
Pharbase Databases.

                  NOW,  THEREFORE,  in  consideration of the premises and of the
mutual covenants and agreements  hereinafter set forth, the parties hereto agree
as follows:

1.       LICENSE RIGHTS

         (a)      WALSH  hereby  grants  to  SOURCE  a  non-exclusive  and  non-
                  transferable  license in the countries of the United  Kingdom,
                  France,  Germany,  Belgium,  The Netherlands,  Spain and Italy
                  (hereinafter  collectively the "Territory" and each separately
                  a "the Country") to:

                  (i)      use the  Pharbase  Databases  described in Appendix A
                           and owned by WALSH and its  subsidiaries  for  inter-
                           nal use in the  development  and  maintenance  of the
                           SOURCE  Group's SOURCE  products and related  servic-
                           es;

                  (ii)     use  the  Pharbase  Databases  for  the  purposes  of
                           collecting,  verifying  and  disseminating  physician
                           linked prescribing information; and

                  (iii)    use  the   information   derived  from  the  Pharbase
                           Databases that becomes part of the SOURCE physi-


                                        2

<PAGE>
                           cian-linked  prescription record in the normal course
                           of selling and exploiting its SOURCE  services.  Such
                           use shall exclude the resale of information  from the
                           Pharbase   Databases  to  third  parties  where  such
                           information is not enhanced by  incorporation  into a
                           SOURCE physician linked  prescribing  record or where
                           it  reduces  WALSH's  ability  to sell  its  Pharbase
                           Database service to third parties.

         (b)      SOURCE shall not,  however,  be  permitted to make  available,
                  sell or license to any third party the  Pharbase  Databases or
                  any data and  information  delivered  to the  SOURCE  Group by
                  WALSH in connection  therewith except as provided in Paragraph
                  1(a)(ii) above.

2.       TERM OF LICENSE

         The initial term of the licenses shall be a period of 10 years from the
         date of execution of this Agreement.  Thereafter,  this Agreement shall
         be automatically renewed for successive five year periods unless either
         WALSH or SOURCE notifies the other party in writing of its intention to
         terminate  the  Agreement at least six months  prior to the  applicable
         renewal year.

3.       ROYALTIES

         (a)      In  consideration  for each  license  right  granted to SOURCE
                  hereunder,  SOURCE shall pay to WALSH a royalty for the fiscal
                  year ending June 30, 1996,  equal to One U.S. Dollar (US$1.00)
                  for each physician in the Country on the Pharbase  Database in
                  regard to whom data and information


                                        3

<PAGE>
                  have been  provided by WALSH to the SOURCE  Group  during that
                  year.  For the fiscal year ending June 30,  1997,  the royalty
                  per  physician  shall be  US$0.75;  for the fiscal year ending
                  June 30, 1998,  the royalty shall be US$0.50 per physician and
                  for  the  fourth  and  subsequent  fiscal  years  US$0.25  per
                  physician,   provided  that  should  SOURCE  fail  to  provide
                  information  to Walsh as updates as provided in Paragraph 8(a)
                  for any fiscal year, Walsh may in addition to any other rights
                  or  remedies  it  may  have,   increase  the  royalty  to  One
                  U.S.Dollar  (US$1.00) for that fiscal year.  The royalty shall
                  be paid by September 30 of each fiscal year during the term of
                  this   Agreement  in  respect  of  the   physician   data  and
                  information  supplied by WALSH for the preceding  fiscal year.
                  For  purposes of this  Agreement a fiscal year shall be the 12
                  month period  beginning July 1 and ending June 30, except that
                  the first fiscal year of this Agreement  shall begin as of the
                  date first set forth above and end June 30, 1996.

         (b)      WALSH shall  increase  the royalty for the  licensed  products
                  specified in Paragraph 3(a) annually.  Said royalties for each
                  Country  in  the  Territory  shall  increase  by the  rate  of
                  inflation in that Country for the previous year. The effective
                  date of the  increase  shall be July 1 of each fiscal year and
                  each WALSH  Company  shall  notify  the SOURCE  Company in the
                  relevant country


                                        4

<PAGE>

                  of the increase and provide  supporting  documentary  evidence
                  therefor.

         (c)      WALSH shall  submit an invoice to SOURCE,  as soon as possible
                  after the  beginning of each  calendar  year,  specifying  the
                  total  number  of  physicians  in regard to whom data has been
                  provided by WALSH to SOURCE.  SOURCE shall pay said invoice on
                  the  later of (i)  twenty  (20)  days  after  receipt  of such
                  invoice and (ii) September 30 of the relevant fiscal year.

4.       IMPROVEMENTS AND ENHANCEMENTS

         During the term of this  Agreement,  WALSH  shall  provide  SOURCE on a
         monthly basis with all updates to the Pharbase  Databases that are made
         by WALSH.  All  maintenance and support  services  provided by WALSH to
         SOURCE in the Territory,  when so requested by SOURCE, shall be charged
         at a rate  of One  Thousand  U.S.  Dollars  (US$1,000)  per  diem  plus
         expenses.

5.       INTELLECTUAL PROPERTY RIGHTS

         The  ownership  of the  Pharbase  Databases,  all  software  associated
         therewith,   and  any   copyrights,   service   marks  and   associated
         intellectual  property rights relating to the Pharbase  Databases shall
         remain  the   exclusive   property   of  WALSH  and  its   wholly-owned
         subsidiaries.

6.       CONFIDENTIALITY

         (a)      All confidential and proprietary  information disclosed by the
                  SOURCE  Group  to WALSH  or to the  personnel  of WALSH in the
                  course of the  performance of this Agreement  shall remain the
                  exclusive property of SOURCE. WALSH shall


                                        5

                  maintain the  confidentiality,  and neither  disclose to third
                  parties  nor use for its own  purposes  (except as  separately
                  agreed),  all such information;  provided,  however,  that the
                  obligation of confidentiality specified above shall not extend
                  to: (i)  information  that is or  subsequently  becomes public
                  knowledge  through no fault of WALSH or (ii)  information that

         (b)      All  confidential  and  proprietary  information  disclosed by
                  WALSH to the SOURCE Group or to the personnel of SOURCE in the
                  course of the  performance of this Agreement  shall remain the

7.       WARRANTIES AND LIMITATIONS

         (a)      WALSH warrants that the Pharbase  Databases licensed hereunder
                  will perform the functions  for which they are being  provided
                  to the SOURCE Group and will materially


                                        6

<PAGE>

                  conform with the specifications agreed on from time to time by
                  the parties.

         (b)      The  express  terms  of  this  Agreement  are in  lieu  of all
                  warranties,  conditions,  terms,  undertakings and obligations
                  implied by statute, common law, custom, trade usage, course of
                  dealing or otherwise,  all of which are hereby excluded to the
                  fullest extent permitted by law.

         (c)      WALSH's  liability to the SOURCE Group arising by reason of or
                  in connection  with a defect in the Pharbase  Databases or any
                  aspect  of the data or  information  provided  by WALSH to the
                  SOURCE Group  hereunder shall not exceed in any Country in the
                  Territory  an amount  equal to the  annual  royalties  paid by
                  SOURCE in that Country.

         (d)      In no event  shall  WALSH be  liable to the  SOURCE  Group for
                  indirect,  consequential  or  incidental  damages,  including,
                  without  limitation,  loss of  profits,  injury to  persons or
                  damage  to or loss of use of any  property,  except  injury to
                  persons  or damage to or loss of use of any  property  arising
                  out of the willful misconduct of WALSH.

8.       ADDITIONAL AGREEMENTS OF PARTIES

         (a)      In the  event  the  SOURCE  Group  acquires  information  with
                  respect to the names,  addresses and telephone  numbers of new
                  physicians  or the new  addresses  and  telephone  numbers  of
                  previously listed  physicians,  SOURCE shall promptly disclose
                  said  information  to the WALSH  subsidiary  in the country in
                  which the  physician  is located.  In such event,  WALSH shall
                  validate the information and, if


                                        7

<PAGE>
                  accurate,  promptly  incorporate the information received from
                  SOURCE in its physician database universe.

         (b)      Pursuant to Clause 1(a)(iii), should SOURCE deliver its SOURCE
                  database service at the physician level to a pharmaceutical or
                  healthcare  company  which  is not a client  of Walsh  for its
                  Pharbase  service in that Country,  Source will pay to Walsh a
                  sum each year that such data is  delivered to the client a fee
                  of 75% of the current  list price of the  Pharbase  service in
                  that Country.

         (c)      In the  event  that  WALSH  develops  a  medical  professional
                  database in the other  countries  in which  SOURCE  intends to
                  develop physician linked prescription  databases,  WALSH shall
                  grant to SOURCE  licenses to utilize  said  databases  for the
                  same  purposes  and  under  substantially   similar  terms  as
                  specified  herein.   The  terms  of  said  licenses  shall  be
                  coincidental  with the term of this Agreement  irrespective of
                  their  commencement  date.  In such event,  the parties  shall
                  execute an amendment to this  Agreement  confirming  the terms
                  and conditions of said additional license rights.

9.       TERMINATION

         (a)      Either party may  terminate  this  Agreement  forthwith at any
                  time by notice  in  writing  to the  other  party if the other
                  party  commits an  irremediable  breach of this  Agreement  or
                  commits any remediable breach and fails to remedy it within 30
                  days after receipt of written notice of the breach.

         (b)      Either  WALSH or SOURCE may  terminate  this  Agreement  as it
                  applies to a particular Country by immediate written notice if
                  the other party becomes insolvent,  or if a court of competent
                  jurisdiction  enters  an order or decree  in  respect  of such
                  party  under  any  bankruptcy  or  similar  law,  approving  a
                  petition for  reorganization  or appoint- ing a custodian  for
                  all  or   substantially   all  its  assets  or  ordering   the
                  liquidation of such party.

         (c)      Each party may  exercise  any right to  terminate  as provided
                  herein by providing  notice of its  intention to terminate the
                  entire  Agreement  or as it is in  effect  in  any  particular
                  Country  in the  Territory.  In the  event  the  Agreement  is
                  terminated in one or more  Countries it shall continue in full
                  force and effect in the remaining countries in the Territory.

         (d)      Notwithstanding  the termination of this Agreement,  the terms
                  and  provisions  of  Paragraph 6 herein  shall  survive.  Upon
                  termination,   each  party  shall  return  to  the  other  any
                  confidential   materials  or  information  in  its  possession
                  pursuant to this Agreement.

                  wholly-owned subsidiary of either WALSH or SOURCE, as the case

                  by the  other  party or to claim a breach  of any term of this
                  Agreement  shall  not be  deemed  to be a waiver  of any right
                  under this Agreement.

         (f)      This   Agreement   shall  be  governed  by  and  construed  in

                              --------------------

         THIS AGREEMENT, entered into as of April 16, 1996, by and between WALSH
INTERNATIONAL INC., a Delaware  corporation  (hereinafter  "WALSH"),  and SOURCE
INFORMATICS INC., a Delaware corporation (hereinafter "SOURCE").


                                   WITNESSETH:
                                   ----------
         WHEREAS, pursuant to the Master Reorganization  Agreement,  dated as of
April 16, 1996 (the "Master  Agreement"),  between  WALSH and SOURCE,  WALSH has
agreed to transfer,  or cause the transfer,  to SOURCE or its  subsidiaries  the
certain assets of certain of WALSH's  subsidiaries  (the companies to which such
assets are being transferred hereinafter referred to collectively as the "SOURCE
Group"  and  the  companies  from  which  such  assets  are  being   transferred
hereinafter referred to collectively as the "WALSH Group"); and
         
         WHEREAS,  for some period of time,  the SOURCE Group will occupy office
space and utilize  certain  tangible  assets owned or leased by companies in the
WALSH Group; and
         
         WHEREAS,  SOURCE now  desires to enter into an  Agreement  pursuant  to
which,  after the transfer to the SOURCE Group pursuant to the Master Agreement,
companies  in the SOURCE  Group  will have the  continued  right and  ability to
occupy and  utilize  the  facilities  of the WALSH  Group.  

         NOW,  THEREFORE,  in  consideration  of the  premises and of the mutual
covenants and  agreements  hereinafter  set forth,  the parties  hereto agree as

         The following terms, whenever used in this Agreement, shall
         have the following meanings:
         (a)      The term "WALSH Companies" shall mean WALSH and the
                  wholly-owned subsidiaries of WALSH listed in Appendix A
                  attached hereto.
         (b)      The  term  "SOURCE   Companies"  shall  mean  SOURCE  and  the
                  wholly-owned  subsidiaries  of  SOURCE  listed in  Appendix  A
                  attached hereto.
2.       SUB-LEASE OF SPACE
         ------------------
         (a)      Commencing   with  the   closing   (the   "Closing")   of  the
                  transactions contemplated by the Master Agreement, WALSH shall
                  cause the WALSH  Companies  to sub-lease  office,  storage and
                  warehouse  space to the SOURCE  Companies in the  countries of
                  Belgium, France, Italy and the United
                  Kingdom.
         (b)      The respective superior leases pursuant to which each
                  WALSH Company occupies office, storage and warehouse
                  space in each of the locations identified on Appendix A
                                                               ----------
                  (hereinafter the "Superior Leases") have, prior to the
                  date hereof, been delivered to representatives of SOURCE.
                  SOURCE hereby acknowledges receipt of the Superior Leas-
                  es.  WALSH hereby represents that each WALSH Company is
                  in compliance with the material terms of the Superior
                  Lease applicable to it.
         (c)      Unless and until otherwise mutually agreed, the specific
                  locations in the WALSH facilities subleased to the SOURCE




                                        2

<PAGE>



                  Companies shall be the space  occupied,  as of the date hereof
                  by the SOURCE Companies in the WALSH facilities.
         
         (d)      WALSH  shall  procure the  consents  of the Lessors  under the
                  Superior  Leases,  if necessary,  to each of the sub-leases to
                  SOURCE  Companies  specified  hereinabove.  In the event  that
                  WALSH fails to procure the necessary consent and SOURCE or any
                  other  SOURCE  Company  suffers  loss or  damage  as a  result
                  thereof,  WALSH shall  indemnify and hold harmless  SOURCE and
                  any  other  SOURCE  Company  from and  against  any  losses or
                  damages  (including  any  reasonable  legal fees that may have
                  been  incurred in connection  therewith)  suffered by any such
                  SOURCE  Company as a result of such failure.  

         (e)      In the event  that any WALSH  Company  sub-leasing  space to a
                  SOURCE Company  pursuant  hereto desires to vacate any office,
                  storage or  warehouse  space that it  presently  occupies,  it
                  shall,  prior  to  seeking  to  sub-lease  said  space  to  an
                  independent  third  party,  afford  the  partic-  ular  SOURCE
                  Company in such country the first opportunity to sub-lease the
                  available space on terms to be mutually agreed.  Neither WALSH
                  nor  any  WALSH  Company  shall  enter  into  any   subsequent
                  sub-lease with a third party without SOURCE's consent on terms
                  more  favorable  than those  offered to the SOURCE  Company in
                  said country.

3.                ADDITIONAL  FACILITIES AND  SERVICES 
                  ------------------------------------

                  In  conjunction  with the  sub-lease  of office,  storage  and
                  warehouse space to SOURCE as provided in Paragraph 2 herein-

         following additional facilities and services:

              including telephone; 

         (b)  Janitorial  service,  trash  collection,security  services and all
              other  maintenance  services;  all the same or  equivalent  to the

              in the sub-leased space;

         (c)  The use of the cafeteria and kitchen facilities, if any, contained
              within the space retained by the WALSH Company.  (SOURCE employees
              of  SOURCE  Companies  shall,  however,  be  required  to pay  the
              standard  charges for the food  consumed  therein.)  

         4.   RENTAL AND OTHER  CHARGES 
              ------------------------  

         (a)  SOURCE or the appropriate  SOURCE Company shall, in  consideration
              for the space and other facilities  provided to it hereunder,  pay
              the rental  charges  specified  in respect of each  country on the
              attached Appendix A. All said rental payments shall be made by the
              fifteenth day of each month. 

         (b)  In addition,  in the event that a WALSH Company is responsible for
              the  payment  of  any  taxes  or  other  local  levies,  including
              landlord's  provisions  for  repairs,  under  the  Superior  Lease
              pursuant  to which the WALSH  Company  occupies  said  space,  the
              SOURCE   Company  sub-  leasing  in  such  location  shall  pay  a
              proportionate  amount of the taxes or other levies due  thereunder
              based upon the amount of space that the SOURCE Company occupies at




                                        4

              said  location as a percentage of the total amount of space leased
              to the WALSH Company.
         
         (c)  All  rental  payments  shall  be delivered  by  the SOURCE Company
              sub-leasing  the premises to the Financial  Director or Controller
              of  the  WALSH  Company  serving  as the  Lessor  under  the  said

              sub-leased  hereunder  shall expire  earlier.  In such event,  the
              sub-lease  between  WALSH and SOURCE in  respect of such  premises
              shall expire  simultaneously with the expiration or termination of
              the Superior  Lease between the WALSH Company and the Lessor.  

         (b)  Each  of  the  SOURCE  Companies  and  the WALSH  Companies  shall
              have  the  right,   in  respect  of  the  individual  sub-  leases
              identified on the attached  Appendix A, to terminate the sub-lease
              at the end of the initial term thereof by providing written notice
              to the  other  at least  six (6)  months  prior to the  expiration
              thereof.  In the  absence,  however,  of such  written  notice  of
              termination given by either party, the particular  sub-lease shall
              automatical- ly continue  thereafter for an additional term of one
              (1) year on the same terms and conditions; provided, however, that
              WALSH shall have the right to increase the rental charges  payable
              pursuant to Paragraph 4(a) by an amount

              increased rental charge. In addition,  SOURCE shall continue to be
              responsible for its pro-rata share of taxes and levies, if any, as
              provided in Paragraph 4(b) hereinabove. Written notice of any such
              increase shall be given by WALSH at least sixty (60) days prior to

              serving as sub-lessor, the lobbies, corridors,  elevators, parking
              lots  and  other  public  portions  of the  leased  premises.  All
              employees of SOURCE  Companies having parking spaces at the leased
              premises  prior to the date hereof  shall be permitted to continue
              to utilize said parking spaces.

              SOURCE  Company  shall  have  the  right  to  place  a sign on the
              exterior  of the  building  in  which  the  premises  are  located
              identifying it as an occupant of the building.  Said sign shall be
              of a size  comparable to the exterior sign  identifying  the WALSH
              Company as an occupant of said premises.  The cost of installation
              of the sign shall be borne by SOURCE. 

7.       LEASEHOLD  IMPROVEMENTS
         -----------------------
         (a)  If the  terms of the  Superior  Lease  between  the  Lessor of the
              premises and the  particular  WALSH  Company  serving as Lessee so
              permit, the right and title to all leasehold improvements existing
              within the sub-leased premises as of the date of execution of this
              Agreement  shall vest in the particular  SOURCE Company  occupying
              said premises.

         (b)  Commencing  on the  date  of  this  Agreement,  SOURCE  shall  not
              undertake  any  alterations,  additions  or  improvements  to  the
              sub-leased  premises  without first having obtained the consent in
              writing of the particular WALSH Company serving as sub-lessor and,
              if required,  the Lessor under the Superior Lease. If such consent
              has been  obtained,  any  leasehold  improvements  rendered to the
              premises by SOURCE shall, if the Superior Lease so permits, become
              the property of SOURCE.

         (c)  At  the  expiration  of  the  term  of  any  particular  sub-lease
              hereunder,  the SOURCE Company serving as sub-lessee  shall, if so
              requested  either by the  particular  WALSH  Company or the Lessor
              under the Superior Lease, remove




                                        7

<PAGE>



              all  leasehold  improvements  or  additions  contained  within the
              sub-leased  premises.  The costs of such removal shall be borne by
              SOURCE.

8.       SUPERIOR LEASE
         --------------
         SOURCE  hereby  agrees  to be bound,  and to cause  each  other  SOURCE
         Company that will occupy any of the premises to be sub-leased hereunder
         to be bound,  by all of the terms and  conditions of the Superior Lease
         between the particular WALSH Company and the Lessor  pertaining to such
         premises. Moreover, SOURCE shall not engage in any activity, or fail to
         take the necessary action if such action is required, that would put it
         and/or WALSH in violation of any  Governmental  regulation or authority
         or  otherwise  put  WALSH  or  any  WALSH  Company  in  breach  of  its
         obligations under any Superior Lease.

9.       CONDITION OF THE SUB-LEASED PREMISES
         ------------------------------------
         (a)  Each  SOURCE  Company  hereby  agrees  to  accept  the  sub-leased
              premises in "as is" condition and WALSH makes no representation of
              any kind concerning said condition.  

         (b)  At the  expiration  of this  Agreement or of any  sub-lease in any
              particular country, SOURCE shall deliver up and surrender to WALSH
              possession of the sub-leased premises in the same condition as the
              premises  were in on the date on which the  SOURCE  Company  first
              occupied the same,  excepting  only  ordinary  wear and tear.  

         (c)  WALSH shall maintain in full force and effect all public liability
              and property damage insurance coverage pertaining to the occupancy
              and use of the leased  premises  that WALSH had in place  prior to
              the effective date of this




                                        8

              sub-lease.  WALSH  shall  name  SOURCE or the  appropriate  SOURCE
              Company as an  additional  insured  under each policy of insurance
              pertaining thereto.
         

         (d)  SOURCE  shall  reimburse  to  WALSH a  proportionate  share of the
              premiums  incurred by WALSH in connection  with the maintenance of
              said insurance coverage based upon the amount of space occupied by
              the SOURCE  Companies as a percentage of the total space  utilized
              by both WALSH and SOURCE at any particular location.  SOURCE shall
              reim- burse WALSH for such proportionate insurance premiums within
              thirty  (30) days  after  receipt  of an  invoice  from WALSH or a
              particular WALSH Company  together with appropriate  documentation
              evidencing  the  payment of the premium by WALSH.  

10.      REPAIRS TO SUB-LEASED PREMISES  
         ------------------------------
         (a)  Whenever  repairs to the  sub-leased  premises  are required to be
              made by the Lessor  under the  Superior  Lease  pertaining  to the
              premises,  WALSH shall take all steps necessary to ensure that the
              Lessor  promptly  fulfills  its  obligation  to repair as provided
              therein.

         (b)  In the event that the  Superior  Lease does not  require  that the
              Lessor undertake any repair of the premises  sub-leased by SOURCE,
              then the appropriate SOURCE Company shall perform and pay for said
              repair to the sub-leased premises.

11.      INDEMNIFICATION 
         ---------------
         (a)  SOURCE shall defend,  indemnify  and hold harmless  WALSH and each
              other WALSH Company from any liability, loss,




                                        9

              cost or expense, including reasonable attorneys' fees, arising out
              of the use and  occupancy  by  SOURCE  Companies  of the  premises
              identified   in   Appendix  A  hereto  and  the   performance   or
              non-performance by any SOURCE Company of any obligation  contained
              in  this  Agreement  (or any  Superior  Lease)  including  but not
              limited to claims  for  injury or damage to  persons  or  property
              arising from any source or cause whatsoever.
         

         (b)  WALSH shall defend,  indemnify  and hold  harmless  SOURCE and any
              SOURCE  Company  from  any  liability,   loss,  cost  or  expense,
              including  reasonable  attorneys' fees, arising out of a breach or
              default by any WALSH Company of any provision of this Agreement or
              any Superior  Lease (other than breaches or defaults of provisions
              of any  Superior  Lease  caused by the action or  inaction  of any
              SOURCE Company).

                      for a fee to be agreed based on the WALSH  Companies' cost
                      for  so  doing. 

         (b)  WALSH shall provide the services  specified  hereinabove to SOURCE

              own  subsidiaries,  divisions or personnel,  subject to reasonable

              services have  previously  been  rendered to the SOURCE  Companies
              when they were part of the WALSH Group. 

         (c)  The  services   provided  in  accordance   with  Paragraph   12(a)
              hereinabove  shall be included in the rental charges  specified in

              purchase  of  supplies,   postage  and  freight,  etc.,  shall  be

13.      TERMINATION
         -----------
         (a)  Either  party  may  terminate  this  Agreement  if the  other  has
              defaulted in any material obligation  hereunder by giving at least
              thirty (30) days' written notice to the breaching party; provided,
              however,  that if the breaching party corrects such default within
              said thirty (30) day period, this Agreement shall continue in full
              force and effect.  

         (b)  Either WALSH or SOURCE may terminate this Agreement, and any WALSH

              applies to a particular  country,  by immediate  written notice if
              the other  party  becomes  insolvent,  or if a court of  competent
              jurisdiction  enters an order or decree in  respect  of such party
              under any  bankruptcy  or similar  law,  approving a petition  for

              all its assets or ordering the liquidation of such party. 

         (c)  Each  party  may  exercise  a right of  termination  as  specified

              Agreement in its entirety  or, in the  alternative,  in respect of
              any particular country in which a material breach has occurred. In
              the event that a notice of  termination is given with respect to a
              particular sub-lease between a WALSH Company and a SOURCE

              Company but not with respect to this  Agreement  in its  entirety,
              this Agreement shall  thereupon  continue in full force and effect
              in  respect  of  the  countries  still  covered  by the  terms  of
              Paragraph 2(a) hereof.
         

         (d)  This  Agreement  shall  automatically  terminate with respect to a
              specific  sub-lease  upon the assignment of such sublease from the
              applicable  WALSH Company to the applicable  SOURCE  Company.  

14.      ADDITIONAL  AGREEMENTS  OF THE  PARTIES  
         ---------------------------------------
         (a)  The SOURCE  Company  conducting  the SOURCE  business  in the U.S.
              shall sub-lease to the WALSH Company conducting the WALSH business
              in the U.S.  the space  occupied  by that  business as of the date
              hereof at 2394 E.  Camelback  Road,  Phoenix,  Arizona  and at 105
              Terry  Drive,  Suite  118,  Newtown,   Pennsylvania.   
         (b)  Unless otherwise  mutually  agreed,  the monthly rental charge for
              such space shall be determined based on the full allocation of all
              space and other  facilities  related costs at that  location.  The
              basis for allocation will be the square footage  occupied pro rata
              by the SOURCE Company  (including  square footage  occupied by its
              other  lessee)  and  the  WALSH  Company  at that  location.  Such
              sub-leases  shall  be under  the  same  terms  and  conditions  as
              provided herein,  except that the WALSH Company may also terminate
              such  subleases  at any time upon at least ninety (90) days notice
              to the applicable SOURCE Company.

Company in the form attached  hereto as Exhibit A (the "Restated  Certificate of
Incorporation")  will  amend  the  terms of the  Series A  Preferred  Shares  as
provided  therein,  with the effect that (i) effective as of the filing with the

Optional Redemption Price" and in the conversion formulas set forth in Section 7
of the Restated Certificate of Incorporation)  shall be appropriately  adjusted;
(ii)  effective  as of the  Spin-Off,  each holder of Series A Preferred  Shares
shall  automatically,  and  without  action on the part of the  Company  or such
holder,  be deemed to have exchanged  one-half the aggregate  number of Series A
Preferred Shares held by such holder for the number of shares of preferred stock
of Source ("Source Preferred Shares"), having the powers, preferences and rights
set forth in the  Certificate of  Designations,  Powers,  Preferences and Rights
attached  hereto  as  Exhibit  B (the  "Source  Certificate  of  Designations"),

exchanged by such holder, times (y) 2; (iii) simultaneously with the issuance of
the Source Preferred Shares in such exchange,  the references to "$24.00" in the
definitions of "Mandatory  Redemption  Price" and "Special  Optional  Redemption
Price" and in the  conversion  formula  set forth in  Section 6 of the  Restated
Certificate of  Incorporation  (as amended in accordance  with clause (i) above)
shall be changed to be  references  to  "$25.34";  and (iv)  effective  upon the
consummation  of the Offering,  each then  outstanding  Series A Preferred Share
shall automatically, without any action by the Company or any holder thereof, be
converted  into a number of shares of Company  Common Stock equal to the greater
of (A) 2.24 and (B) the number determined by dividing $25.34 by 74% of the price
to the public of the Company  Common  Stock sold in the  Offering.  Concurrently
with the Spin-Off, the Company will exchange Series A Preferred Stock for Source
Preferred Shares pursuant to the Restated Certificate of Incorporation.

                  Company  may  without  violating  the  provisions  of  Section

<PAGE>


                  party of all of the outstanding  shares of Common Stock of the
                  Company so long as (i) in  connection  with such  transaction,
                  holders of shares of Common  Stock of the  Company  shall have
                  the right to receive  the same  securities  or other  property
                  (containing  the same terms and the same  rights) with respect
                  to each such  share of Common  Stock and (ii) the  holders  of
                  Shares and  Conversion  Shares shall have the right to receive
                  in connection  with such  transaction the same such securities
                  or other property  (including the same terms and with the same
                  rights) on  account  of the  number of shares of Common  Stock
                  which are then represented by such Conversion  Shares or which
                  are then  obtainable  upon  conversion  of such  Shares as are
                  received  by the other  holders of Common  Stock on account of
                  the shares of Common Stock held by such holders.

                  (iii)  agree  with  the  Company  that,   effective  upon  the
         consummation  of the Offering and  conversion of the Series A Preferred
         Shares as  contemplated  in paragraph  1(iv) hereof,  the provisions of
         Section  7 of each  of the  Purchase  Agreements  (except  for  each of
         Sections 7.1, "Use of Proceeds";  7.7,  "Environmental  Matters";  7.18
         "Listing  of  Shares";  7.19,  "Securities  Act  Registration";   7.20,
         "Maintenance  of Public Market"  (amended as provided  above) and 7.22,
         "Delivery of Information,"  which shall remain in full force and effect
         in accordance with the Purchase Agreements),  shall terminate and be of
         no further force and effect.

                  (b) Each of the Preferred  Stockholder  Parties  hereby waives
any rights under Section 19 of the Walsh Stockholders' Agreement or otherwise to
acquire  Company  Common  Stock in  connection  with the issuance of warrants to
purchase up to 200,000  shares of Company  Common Stock at an exercise  price of
$6.00 per share to Comdisco, Inc.

                  5. Certain Registration Rights Matters. Pursuant to Section 15
of each of the Purchase Agreements, the Preferred Stockholder Parties, being the
holders of at least  two-thirds in interest of the "Conversion  Shares" (as such
term is defined in the Purchase Agreements),  hereby waive written notice of the
Offering  and any right to request  that  Conversion  Shares be  included in the
Offering under Section 8.2(a) of each of the Purchase Agreements; provided, that
such waivers are conditioned upon the Company obtaining similar waivers from any
other  persons  possessing  registration  rights with  respect to the  Company's
securities  and that the  Offering  consists  solely  of the  offer  and sale of
securities by and on behalf of the Company.  The Company  confirms,  pursuant to
Section 8.2(b) of each of the Purchase Agreements, that the managing underwriter
of the  Offering has advised the Company  that it has  determined  in good faith
that the inclusion of Conversion Shares or any other securities of the




                                        4

Company would  jeopardize the successful  sale of the Company Common Stock to be
sold in the Offering.

                  6. Termination of Walsh Stockholders'  Agreement.  Pursuant to
Section  33 of the Walsh  Stockholders'  Agreement,  the  Preferred  Stockholder
Parties,  constituting  the holders of a majority of the shares of Common  Stock
currently  held by the "New  Shareholder  Group" (as such term is defined in the
Walsh Stockholders'  Agreement),  and the Company agree that, effective upon the
consummation  of the  Offering and the receipt of the  requisite  consent of the
"Welsh Stockholders", the "Crown Stockholders" and the "Management Stockholders"
(as such terms are  defined  in the Walsh  Stockholders'  Agreement),  the Walsh
Stock- holders' Agreement shall terminate and be of no further force and effect.

                  7. ELI Observer  Rights.  Following  the  consummation  of the
Offering,  for so  long  as  Equity-Linked  Investors,  L.P.  and  Equity-Linked
Investors II, L.P.  (collectively,  the "ELI  Stockholders")  shall hold, in the
aggregate,  at least 1/2 of the number of  Conversion  Shares held by them as of
the date of  consummation  of the Offering (as such number may be  appropriately
adjusted to take account of stock splits,  stock  dividends,  recapitalizations,
reclassifications  and  other  similar  events),  the ELI  Stockholders  (acting
through  the  holder or holders  of a  majority  of the  Shares  held by the ELI
Stockholders)  will  have  the  collective  right,  at the  request  of the  ELI
Stockholders,  to send one  representative to meetings of the Company's Board of
Directors,  such  representative  to act as an observer  without a vote or other
rights as a director  (except the right to receive  sufficient  notice to enable
such attendance and the right to receive all other  communications,  information
and materials furnished,  from time to time, to directors of the Company and the
right to  receive  reimbursement  for  travel  expenses  to the same  extent  as
directors of the Company);  provided, that any such representative shall, before
attending any meetings of the Company's Board of Directors,  execute and deliver
to the Company a  confidentiality  agreement  in form and  substance  reasonably
satisfactory to the Company and its counsel.

                  8.  Representations  and Warranties of the Company and Source.
Each of the Company and Source hereby  represents and warrants to each holder of
Series  A  Preferred  Shares,  as of the date  hereof  and as of the date of the
Reorganization Closing, as follows:

                  (a) Each of the  Company  and  Source  is a  corporation  duly
         organized,  validly existing and in good standing under the laws of the
         State of Delaware, and is duly qualified, licensed and authorized to do
         business and is in good standing in each  jurisdiction in which it owns
         or leases any material property or in which the conduct of its business

<PAGE>

         requires  it to so  qualify  or to be  so  licensed,  except  for  such
         jurisdictions  where the failure to so qualify or be so licensed  would
         not have a material  adverse  effect on the  Company or Source,  as the
         case may be.

                  (b)  The  Company  has  all  requisite   corporate  power  and
         authority  to enter  into  this  Agreement  and,  upon  receipt  of the
         stockholder  consents referred to in paragraph 2 hereof,  will have all
         requisite  corporate power and authority to consummate the transactions
         contemplated hereby (including,  without limitation,  the Offering, the
         Spin-Off and the issuance of Conversion  Shares upon  conversion of the
         Series A Preferred  Shares in accordance with the Restated  Certificate
         of Incorporation). This Agreement has been duly executed by the Company
         and constitutes the legal, valid and binding obligation of the Company,
         enforceable against it in accordance with its terms.

                  (c) The Conversion Shares,  when issued upon conversion of the
         Series A Preferred  Shares in accordance with the Restated  Certificate
         of Incorporation,  will be duly authorized,  validly issued, fully paid
         and non-assessable.

                  (d) Source has all requisite  corporate power and authority to
         enter  into  this  Agreement  and  the  Stockholders  Agreement  and to
         consummate the transactions contemplated hereby and thereby (including,
         without  limitation,  the  issuance  and  delivery  of shares of Source
         Preferred Stock in accordance with the terms hereof and of the Restated
         Certificate of Incorporation). This Agreement has been duly executed by
         Source and  constitutes  the legal,  valid and  binding  obligation  of
         Source,  enforceable  against it in  accordance  with its  terms.  Upon
         execution  and  delivery  by Source of the  Stockholders  Agreement  as
         contemplated  hereby,  the  Stockholders  Agreement will constitute the
         legal, valid and binding obligation of Source,  enforceable  against it
         in accordance with its terms.

                  (e) The authorized  capital stock of Source consists solely of
         common stock and an aggregate  2,000,000 shares of preferred stock, the
         only  designated  series  of  which  is the  Source  Preferred  Shares.
         Immediately  prior to the  Spin-Off,  the only  issued and  outstanding
         shares  of  capital  stock of Source  shall be shares of Source  Common
         Stock  and  the  Source  Preferred  Shares.  Immediately  prior  to the
         Spin-Off,  all the Source  Preferred  Shares  will be duly  authorized,
         validly issued, fully paid and non-assessable, and the Company will own
         all the Source  Preferred Shares free and clear of any and all pledges,
         security   interests,   liens,   adverse   claims,   charges  or  other
         encumbrances  of any nature  whatsoever.  The  shares of Source  Common
         Stock into  which the Source  Preferred  Shares  are  convertible  (the
         "Source Conversion

         Source  Preferred  Shares in accordance with the Source  Certificate of
         Designations   and,  when  so  issued  and  delivered,   will  be  duly
         authorized, validly issued, fully paid and non-assessable.

                  (f) The  exchange  of  Series A  Preferred  Stock  for  Source
         Preferred Shares pursuant to the Restated  Certificate of Incorporation
         will transfer  valid title to such Source  Preferred  Shares,  free and
         clear  of any and  all  pledges,  security  interests,  liens,  adverse
         claims, charges or other
         encumbrances of any nature whatsoever.

                  (g)  The  execution  and  delivery  of this  Agreement  by the
         Company and Source and of the Source Stockholders  Agreement by Source,
         and  the  performance  by  each  of  the  Company  and  Source  of  its
         obligations  hereunder and thereunder  (including,  without limitation,
         the Offering, the Spin-Off, the issuance of the Source Preferred Shares
         in  exchange  for  Series  A  Preferred  Shares  and  the  issuance  of
         Conversion  Shares upon conversion of the Series A Preferred  Shares in
         accordance  with the Restated  Certificate of  Incorporation)  will not
         violate any provision of law, any order of any court or other agency of
         government,  the  Restated  Certificate  of  Incorporation  or Restated
         By-Laws of the Company,  the Certificate of Incorporation or By-Laws of
         Source, the Source Certificate of Designations,  or any judgment, award
         or decree or any  indenture,  agreement  or other  instrument  to which
         either  of the  Company  or  Source is a party or by which any of their
         respective assets are bound or affected,  or conflict with, result in a
         breach or  constitute  (with due  notice or  passage of time or both) a
         default  under,  any such  indenture,  agreement  or other  instrument,
         except for any such violations,  conflicts, breaches or defaults which,
         individually  or in the  aggregate,  would not materially and adversely
         affect either of the Company or Source.

                  9. Representations and Warranties of the Preferred Stockholder
Parties.  Each  of the  Preferred  Stockholder  Parties  hereby  represents  and
warrants  to  each  of  the  Company  and  Source  and to  the  other  Preferred

<PAGE>
                  (b) Such Preferred  Stockholder  Party has all requisite power
         and  authority  to enter  into this  Agreement  and to  consummate  the
         transactions contemplated hereby. This Agreement has been duly executed
         by such Preferred  Stockholder  Party and constitutes the legal,  valid

         against it in accordance with its terms.

                  (c)  Such   Preferred   Stockholder   Party  has  had  a  full
         opportunity  to request from the Company and to review and has received
         all  information  which  it  deems  relevant  in  connection  with  the
         Spin-Off, the issuance of the Conversion Shares and the issuance of the
         Source Preferred Shares.

                  (d)  Such  Preferred   Stockholder  Party  is  an  "accredited

         investment  and not with a view to or for sale in  connection  with any
         distribution thereof in violation of any securities laws.

                  (f) Such Preferred  Stockholder Party understands that none of
         the Source Preferred Shares or the Source  Conversion  Shares have been
         registered  under the  Securities  Act by reason of their issuance in a
         transaction exempt from the registration requirements of the Securities
         Act.

                  (g) Such  Preferred  Stockholder  Party  understands  that the

         securities  will bear a legend to such effect and the Company will make
         a notation on its transfer books to such effect.

1)       The Common Share equivalents consist of stock options, warrants and the
         Series A  Convertible  Preferred  Stock.  The Stock options and warrant
         equivalent  shares are  calculated  using the treasury stock method and
         the  $12.00  initial  public  offering  price per share as the  average
         and/or closing price for all periods.  For the purposes of this Exhibit
         all common  equivalent  shares have been  included  even where they are
         dilutive.


2)       The Common Stock equivalents consist of stock options, warrants and the
         Series A Convertible  Preferred Stock.  Common  equivalent  shares from
         convertible  preferred stock (using the if- converted method) and stock
         options  and  warrants  (using the  treasury  stock  method)  have been
         included in the computation when dilutive (except that, pursuant to the
         Securities  and Exchange  Commission  rules,  the Series A  Convertible
         Preferred  Stock which has  converted  into Common Stock in  connection
         with the Company's  initial public offering is included as if converted
         at  the  original  date  of  issuance  even  though  inclusion  may  be
         anti-dilutive).  Pursuant to the  Securities  and  Exchange  Commission
         Staff  Accounting  Bulletin  all common and  common  equivalent  shares
         issued by the  Company at an exercise  price  below the assumed  public
         offering  price  during the  twelve-month  period prior to the offering
         have been included in the  calculation as if they were  outstanding for
         all periods  through  December 31, 1995, the interim period included in
         the initial  public  offering  prospectus,  (using the  treasury  stock
         method and the  initial  public  offering  price of $12.00 per  share).
         After December 31, 1995 Common  equivalent  shares are included only if
         they have a dilutive effect.
