ITEM 3.  SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION.

    On April 1, 1997, NFO Research, Inc., a Delaware corporation ("NFO"),
    acquired one hundred percent (100%) of the outstanding stock of
    Prognostics, a California corporation (the "Company") and provider of
    survey-based quantitative customer satisfaction research to information
    technology companies.  The transaction was effected through the issuance of
    1.726 million newly issued shares of NFO Common Stock pursuant to the terms
    of an Agreement and Plan of Merger dated as of March 20, 1997 (the "Merger
    Agreement") by and among Prognostics, NFO, Prognostics Corp., a Delaware
    corporation and wholly-owned subsidiary of NFO ("Prognostics"), and the
    shareholders of the Company, including James B. Wood and the Trust.  Upon
    consummation of the transaction, the Company was merged into and with
    Prognostics and became a wholly-owned subsidiary of NFO (the "Merger"). 
    Pursuant to the terms of the Merger Agreement, each share of non-voting
    Common Stock of the Company was converted into the right to receive
    59.99477 shares of NFO Common Stock and each share of Preferred Stock of
    the Company was converted into the right to receive 4.72813 shares of NFO
    Common Stock.  As a result, James B. Wood received an aggregate of six
    hundred fifty-one thousand eight hundred forty-four (651,844) shares of NFO
    Common Stock (in exchange for an aggregate of ten thousand eight hundred
    sixty-five (10,865) shares of the Company's non-voting Common Stock) and
    the Trust received an aggregate of nine hundred seventy thousand eight
    hundred forty-four (970,844) shares of NFO Common Stock (in exchange for an
    aggregate of fifteen thousand (15,000) shares of the Company's Preferred
    Stock and fifteen thousand (15,000) shares of the Company's non-voting
    Common Stock).  Pursuant to the terms of the Indemnification and Escrow
    Agreement entered into concurrently with the consummation of the Merger,
    five percent (5%) of the shares of NFO Common Stock received by the
    Company's shareholders pursuant to the Merger Agreement were deposited in
    escrow to secure certain indemnification obligations of the Company's
    shareholders in connection with the Merger.  The transaction was accounted
    for as a pooling of interests.  The closing price of a share of NFO Common
    Stock on the Nasdaq National Market System on April 1, 1997 was Seventeen
    and Seven-Eighths Dollars ($17.875).  Walter P. Smith is the settlor and
    sole trustee of the Trust.  Pursuant to the terms of the Trust, Mr. Smith
    has sole investment and voting power over the shares of NFO Common Stock
    held by the Trust.

ITEM 4.  PURPOSE OF TRANSACTION.

    The purpose of the transaction was to effect the acquisition of the Company
    by NFO.  The shares of NFO Common Stock beneficially owned by the reporting
    persons were received in exchange for shares of Preferred and non-voting
    Common Stock of the Company pursuant to the terms of the Merger Agreement
    described in Item 3 above which is incorporated herein by reference.  In
    addition, upon consummation of the Merger, NFO and each of the Company's
    shareholders entered into a Registration Rights Agreement which provides
    the shareholders certain rights to register under the Securities Act of
    1933, as amended, the shares of NFO Common Stock received by such
    shareholders pursuant to the Merger.  Upon consummation of the Merger, Mr.
    Wood also became President and Chief Executive Officer of Prognostics
    pursuant to the terms of an Employment Agreement with Prognostics, and
    Walter B. Smith entered into a Consulting Agreement with Prognostics
    pursuant to which Mr. Smith agreed to provide consulting services to
    Prognostics on various matters relating to its current and future business. 
    Mr. Wood and the Trust may from time to time sell, assign, gift or
    otherwise transfer their respective shares of NFO Common Stock in
    accordance with applicable securities laws and subject to compliance with
    any applicable contractual restrictions.

    Except as set forth above, no person named in Item 2 to this Schedule 13D
    has any plans or proposals which relate to or would result in: (a) the
    acquisition by any such person of any additional securities of NFO, or the
    disposition of securities of NFO; (b) an extraordinary corporate
    transaction, such as a merger or liquidation, involving NFO or any of its
    subsidiaries; (c) a sale or transfer of a material amount of assets of NFO
    or any of its subsidiaries; (d) any change in the present Board of
    Directors or management of NFO, including any plans or proposals to change
    the number or term or directors or to fill any existing vacancies on the
    Board; (e) any material change in the present capitalization or dividend
    policy of NFO; (f) any other material change in NFO's business or corporate
    structure; (g) changes in NFO's charter, bylaws or instruments
    corresponding thereto or other actions which may impede the acquisition of
    control of NFO by any person; (h) causing a class of securities of NFO to
    be delisted from a national securities exchange or to cease to be
    authorized to be quoted in an inter-dealer quotation system of a registered
    national securities association; (i) a class of equity securities of NFO
    becoming eligible for termination of registration pursuant to Section
    12(g)(4) of the Securities Exchange Act of 1934; or (j) any action similar
    to any of the foregoing.

                             AGREEMENT AND PLAN OF MERGER



    AGREEMENT AND PLAN OF MERGER, dated as of March 20, 1997 (the "Agreement"),
by and among PROGNOSTICS, a California corporation (the "Company"), NFO
RESEARCH, INC., a Delaware corporation ("NFO"), Prognostics Corp., a Delaware
corporation and wholly-owned subsidiary of NFO ("Merger Sub"), and the
shareholders of the Company (the "Shareholders"), who are James B. Wood, The
Walter P. Smith Trust (2120/86), Jay H. Friedman and Thomas Rich.  The Company
and Merger Sub are sometimes collectively referred to herein as the "Constituent
Corporations."

    WHEREAS, NFO is entering into this Agreement to facilitate the acquisition
of the Company by Merger Sub, a wholly-owned subsidiary of NFO.

    WHEREAS, the respective Boards of Directors of the Company and Merger Sub
each have adopted resolutions approving this Agreement pursuant to which, among
other things, the Company will be merged with and into Merger Sub (the "Merger")
on the terms and conditions contained herein and in accordance with the Delaware
General Corporation Law (the "DGCL") and the Corporation Code of the State of
California (the "California Code").

    WHEREAS, it is intended that the Merger shall be accounted for as a
"pooling of interests" for accounting purposes.

    NOW THEREFORE, in consideration of the premises and the representations,
warranties and covenants contained herein, and intending to be legally bound
hereby, the parties hereto agree as follows

                                      ARTICLE 1
                                      THE MERGER

    1.1     THE MERGER.  Upon the terms and subject to the conditions of this
Agreement, at the Effective Time (as defined below) and in accordance with the
DGCL and the California Code, the Company shall be merged with and into Merger
Sub, which shall be the surviving corporation in the Merger (hereinafter
sometimes referred to as the "Surviving Corporation') and shall continue its
corporate existence under the laws of the State of Delaware.  At the Effective
Time, the separate existence of the Company shall cease.

    For Federal income tax purposes, the parties intend that the transactions
herein consummated shall be treated as a tax-free reorganization within the
meaning of Sections 368(a)(1)(A) and 368(a)(2)(D) of the Internal Revenue Code
of 1986, as amended (the "Code").  The parties hereto further agree that in
connection with the Common Stock, the Preferred Stock and the Merger
Consideration, as those terms are defined in Section 2.1 of the Agreement, that
the Merger Consideration represents full and complete consideration for the
Common Stock the Preferred Stock and the Company's Tangible and Intangible
Assets (as hereinafter defined) and that no portion of the Merger Consideration
has been paid for any other intangibles such as employment agreements or
non-compete agreements.  It is further agreed that the rights under any
noncompete agreement among the parties hereto (whether in this Agreement or
under separate agreement) have no economic significance separate from the
Company's goodwill.  Each party shall not take a position on any return or
report filed with any Tax (as defined in Section 4.12(m)) authority which is
inconsistent with this Section 1.1, and shall use their reasonable efforts to
sustain such reporting.  Each party shall give the other prompt notice of any
challenges or investigations undertaken by any Tax authority in connection with
such reporting, and shall keep such other party fully informed of all aspects of
such ongoing challenge or investigation.

$.01 per share, of Merger Sub issued and outstanding immediately prior to the
Effective Time shall, by virtue of the Merger and without any action on the part
of the holder thereof, be converted into one share of common stock, par value
$.01 per share, of the Surviving Corporation.

    2.3     SURRENDER OF COMMON STOCK AND PREFERRED STOCK.  At the Closing (as

so contemplated.  This Agreement has been duly and validly authorized, executed
and delivered by each of NFO and Merger Sub and constitutes a legal, valid and
binding agreement of each of NFO and Merger Sub, enforceable against it in
accordance with its terms.

    3.3     ABSENCE OF BREACH.  The execution and delivery by each of NFO and
Merger Sub of this Agreement, and the performance thereby of its obligations
hereunder, will not (i) conflict with or result in a breach of any of the
provisions of the certificate of incorporation or by-laws thereof, (ii) require
any consent, approval or notice under or conflict with or result in a violation
or breach of, or constitute (with or without notice or lapse of time or both) a
default (or give rise to any right of termination, cancellation or acceleration)
under any of the terms, conditions or provisions of any material note, bond,
mortgage, indenture, license, agreement or other instrument or obligation to
which NFO or Merger Sub is a party or by which any of them or any of their
properties or assets may be bound, or (iii) subject to the obtaining of the
governmental and other consents referred to in Section 3.4, contravene any law,
rule or regulation of any state or of the United States or any political
subdivision thereof or therein, or any order, writ, judgment, injunction,
decree, determination or award currently in effect, which, singly or in the

or declaration or filing with any governmental agency or regulatory authority on
the part of either NFO or Merger Sub which has not been made is required in

    3.5     LITIGATION.  There is no action or proceeding or investigation
pending or, to the best knowledge of NFO or Merger Sub, threatened against or
involving either NFO or Merger Sub, which, if determined adversely, would
materially and adversely affect the financial condition, business, assets or
results of operations thereof or the ability thereof to perform its obligations
hereunder.

    3.6     FULL DISCLOSURE.  The Quarterly Report on Form 10-Q (the "Form
10-Q") of NFO for the fiscal quarter ended September 30,1996 (which has been
delivered or made available by NFO to each Shareholder), as of the date thereof,
neither contained any untrue statement of a material fact nor omitted to state a
material fact necessary in order to make the statements therein in light of the
circumstances under which they were made, not misleading.

    3.7     NO MATERIAL ADVERSE CHANGE.  Since the date of the filing of the
Form 10-Q, (i) there has been no material adverse change in the business,
assets, prospects, condition (financial or otherwise) or results of operations
(the "Condition") of NFO, (ii) to the knowledge of NFO there is no condition or
state of facts or any change that is threatened that if it were to occur could
reasonably be expected to have a material adverse effect on the Condition of
NFO, and (iii) there has not been any damage, destruction or loss materially
adversely affecting the Condition of NFO, whether or not covered by insurance.

    3.8     ACCOUNTING MATTERS.  Neither NFO nor, to its best knowledge, any of
its subsidiaries has taken or agreed to take any action that would prevent NFO
from accounting for the business combination to be effected by the Merger as a
"pooling of interests."

    3.9     POOLING LETTER.  NFO has caused NFO's independent auditors, to
deliver to NFO on or prior to the date hereof a draft letter setting forth the
preliminary conclusion of Arthur Andersen LLP that, assuming the Company is a
corporation eligible to be party to a transaction seeking pooling of interests
accounting treatment and that the participation of the Company in the Merger
will not, in and of itself, disqualify the Merger from qualifying for pooling of
interests accounting treatment if consummated in accordance with this Agreement,
and NFO has delivered a true and complete copy of such letter to the
Shareholders.

    3.10    STATUS OF NFO SHARES.  The shares of NFO Common Stock to be issued
to the Shareholders will, when so issued, be duly and validly issued, fully paid
and non-assessable.

    3.11    TAXES.

            (a)    At all times prior to the Effective Time, NFO will be in
control of Merger Sub used in this Agreement, "Control" shall have the meaning
found in Section 368(c) of the Code ("Control").

            (b)    NFO has no present plan or intention to cause Merger Sub to
issue additional shares of its stock, or to take any other action that would
result in NFO losing Control of Merger Sub.

            (c)    NFO has no present plan or intention to reacquire any of the
NFO Common Stock issued pursuant to the transactions contemplated by this
Agreement.

            (d)    NFO has no present plan or intention to liquidate Merger
Sub, to merge Merger Sub with or into another corporation (other than the
Company); to sell or otherwise dispose of the stock of Merger Sub; or to cause
Merger Sub to sell or otherwise dispose of any of its assets or of any of the
assets acquired from

Company in the reorganization, except for dispositions made in the ordinary
course of business or transfers of assets to a corporation controlled by Merger
Sub, as described in Section 368(a)(2)(C) of the Code.

            (e)    Neither NFO nor Merger Sub is, or will be on the Effective
Time, an investment company within the meaning of Code Section 368(a)(2)(F)(iii)
and (iv).

if any, incurred in connection with the transactions contemplated by this
Agreement.

existing and in good standing under the laws of the State of California and has
all requisite corporate power and authority to own, lease and operate its
properties and to carry on its business as now being conducted.  The Company is
duly qualified or licensed and in good standing to do business in each
jurisdiction in which the property owned, leased or operated by it or the nature
of the business conducted by it makes such qualification or licensing necessary,
except where the failure to be so duly qualified or licensed and in good
standing would not individually or in the aggregate affect materially and
adversely the business, assets, properties, condition (financial or otherwise)
or the results of operations thereof.  The jurisdictions in which qualification
of the Company has been considered and accomplished are listed on Schedule 4.1.
The Company has heretofore delivered to NFO or Merger Sub accurate and complete
copies of the articles of incorporation.

consists of 100,000 shares of Common Stock and 50,000 shares of Preferred Stock.
As of the date hereof, 27,595 shares of Common Stock are issued and outstanding
and 15,000 shares of Preferred Stock are issued and outstanding.  Each
Shareholder owns beneficially and of record that number of shares of Common
Stock and Preferred Stock set forth opposite his or her name on Schedule 4.2
free and clear, other than as set forth on Schedule 4.2, of any Lien (as defined
in Section 4.26) and will surrender such shares pursuant to Section 2.3 free and
clear of any lien or other encumbrance.  No other capital stock of the Company
is authorized or issued.  Except as set forth on Schedule 4.2, all issued and
outstanding shares of capital stock of the Company have been duly authorized and
are validly

issued, fully paid, non-assessable and free of preemptive rights.  There are
not, and at the Effective Time there will not be, any existing Liens with
respect to, or any existing options, warrants, calls, subscriptions, stock
appreciation rights, or other rights or other agreements, arrangements or
commitments obligating the Company to issue, transfer or sell, or securities or
rights convertible or exchangeable for, any shares of capital stock of the
Company.

    4.3     SUBSIDIARIES.  Schedule 4.3 sets forth a complete and accurate list
of all of the subsidiaries of the Company, together with their respective
jurisdictions of incorporation or organization.  Each such subsidiary is
directly wholly-owned by the Company.  Except as set forth on Schedule 4.3, as
of the date hereof, the Company does not own, and as of the Closing Date, the
Company will not own, any direct or indirect equity interest in any corporation,
partnership, joint venture or other entity.

    4.4     AUTHORITY RELATIVE TO THIS AGREEMENT.  Each of the Company and the
Shareholders has full power and authority to execute and deliver this Agreement
and to consummate the transactions contemplated hereby.  The execution and

meaning of Section 1445(b)(2) of the Code.

            (l)    There is no contract, agreement, plan or arrangement
covering any person that, individually or collectively, could give rise to the
payment of any amount that would not be deductible by the Company by reason of
Section 280G of the Code, except for such amounts the nondeductibility of which
would not have a material adverse effect on the Condition of the Company.

            (m)    For purposes of this Agreement, "Tax" or "Taxes" means all
federal, state, county, local, foreign and other taxes (including, without
limitation, income, profits, premium, estimated, excise, sales, use, occupancy,

transfer, withholding, employment, unemployment compensation, payroll-related
and property taxes, import duties and other governmental charges and

with respect thereto, and including expenses associated with any proposed
adjustment related to any of the foregoing (including advice in connection with
contesting such adjustment).

    4.13    ERISA; EMPLOYEE BENEFITS.

            (a)    Schedule 4.13 identifies each employment, severance or
similar contract or arrangement (whether or not written) and each plan, policy,
fund, program or contract or arrangement (whether or not written) providing for
compensation, bonus, profit-sharing, stock option, or other stock related rights
or other forms of incentive or deferred compensation, vacation benefits,
insurance coverage (including any self-insured arrangements) health or medical
benefits, disability benefits, worker's compensation, supplemental unemployment
benefits, severance benefits and post-employment or retirement benefits
(including compensation, pension, health, medical or life insurance or other
benefits) under which the Company or its subsidiaries have or in the future
could have any liability ("Benefit Plans").  Schedule 4.13(a) further identifies
each Benefit Plan which (i) is a multi-employer plan (within the meaning of
Section 3(37) of the Employee Retirement Income Security Act of 1974, as amended
("ERISA"), (ii) is a plan, other than a multi-employer plan, subject to Title IV
of ERISA (a "Title IV Plan") or (iii) is maintained in connection with any trust
described in Section 501 (c)(9) of the Code.

            (b)    The Company has furnished to NFO or Merger Sub copies of the
Benefit Plans (and, if applicable, related trust agreements) and all amendments

report (Form 5500 including, if applicable, Schedule B thereto), the most recent

actuarial valuation report prepared in connection with any Benefit Plan, and the
most recent IRS determination letter received with respect to any Benefit Plan.

            (c)    As of the Effective Time, the fair market value of the
assets of each Title IV Plan (excluding for these purposes any accrued but
unpaid contributions) including, without limitation, the Prognostics Defined
Benefit Pension Plan (the "PDBPP"), exceeded the present value of all benefits
accrued under such Title IV Plan determined on a termination basis using the
assumptions established by the Pension Benefits Guaranty Corporation ("PBGC") as
in effect on such date.  As of the Effective Time, the aggregate unfunded
liability of the Company or its subsidiaries in respect of all Benefit Plans
described under Sections 4(b)(5) or 401 (a)(1) of ERISA, computed using
reasonable actuarial assumptions and determined as if all benefits under such
plans were vested and payable as of such date, did not exceed $0.00.

            (d)    No transaction prohibited by Section 406 of ERISA or Section
4975 of the Code, has occurred with respect to any employee benefit plan or
arrangement which is covered by Title I of ERISA which transaction has or will
cause the Company to incur any liability under ERISA, the Code or otherwise,
excluding transactions effected pursuant to and in compliance with a statutory
or administrative exemption.  Neither the Company nor any affiliate of the
Company has (i) engaged in, or is a successor or parent corporation to an entity
that has engaged in, a transaction described in Sections 4069 or 4212(c) of
ERISA or (ii) incurred, or reasonably expects to (A) any liability under Title
IV of ERISA arising in connection with the termination of, or a complete or
partial withdrawal from, any plan covered or previously covered by Title IV of
ERISA or (B) any liability under Section 4971 of the Code that in either case
could become a liability of the Company or NFO, Merger Sub or any of their ERISA
affiliates.  No condition exists that (i) could constitute grounds for
termination by the PBGC of any employee benefit plan that is subject to Title IV
of ERISA that is maintained by the Company or any of its ERISA affiliates or
(ii) presents a material risk of complete or partial withdrawal from any
multi-employer plan, as defined in Section 3(37) of ERISA, which could result in
the Company, NFO or Merger Sub or any ERISA affiliate of any of them incurring a
withdrawal liability within the meaning of Section 4201 of ERISA.  The assets of
the Company are not now, nor will they after the passage of time be, subject to
any lien imposed under code Section 412(m) by reason of a failure of any of the
Company or its affiliates, the Company to make timely installments or other
payments required under Code Section 412.  If a "complete withdrawal" by the
Company and all of its ERISA affiliates were to occur as of the Closing Date
with respect to all Multiemployer Plans, neither the Company nor any of its
ERISA affiliates would incur any material withdrawal liability under Title IV of
ERISA.

            (e)    Each Benefit Plan that is intended to be qualified under
Section 401(a) of the Code is so qualified and has been so qualified during the
period since its adoption; each trust created under any such Plan is exempt from
tax under Section 501 (a) of the Code and has been so exempt since its creation.
Each Benefit Plan has been maintained in substantial compliance with its terms
and with the requirements prescribed by any and all applicable statutes, orders,
rules and regulations, including but not limited to ERISA and the Code.

            (f)    The Company does not have any current or projected liability
in respect of post-employment or post-retirement health or medical or life
insurance benefits for retired, former or current employees of the Company,
except as required to avoid excise tax under Section 49808 of the Code.

            (g)    There is no contract, plan or arrangement (written or
otherwise) covering any employee or former employee of the Company that,
individually or collectively, could give rise to the payment of any amount that
would not be deductible pursuant to the terms of Section 280G of the Code

            (h)    There has been no failure of a group health plan (as defined
in Section 5000(b)(1) of the Code) to meet the requirements of Code Section
4980B(f) with respect to a qualified beneficiary (as defined in Section
4980(9)).  The Company has not contributed to a nonconforming group health plan
(as defined in Section 5000(c)) and no affiliate of the Company has incurred a
tax under Section 5000(a) which is or could become a liability of the Company.

            (i)    No employee or former employee of the Company will become
entitled to any bonus, retirement, severance, job security or similar benefit or
enhanced such benefit (including acceleration of vesting or exercise of an
incentive award) as a result of the transactions contemplated hereby.

schedules and timetables contained in Environmental Laws or contained in any
plan, judgment, injunction, notice or demand letter issued, entered, promulgated
or approved thereunder.

            (c)    There is no civil, criminal or administrative action, suit,
demand, claim, hearing, notice or demand letter, notice of violation,
investigation, or proceeding pending or, to the knowledge of any Shareholder or
the Company, threatened against the Company or its subsidiaries relating in any
way to Environmental Laws.

with the Company or its subsidiaries.

    4.20    LITIGATION INVOLVING SHAREHOLDERS.  No Shareholder is a party to,

obligations hereunder.

Company in good faith on a reasonable basis.  The assumptions on which the
Budget is based are consistent with normal budgeting practices (including,
without limitation, accounting practices) of the Company and with historical
conditions applicable to the business of the Company and its subsidiaries.
Nothing has come to the attention of any Shareholder or the Company to indicate
that the Budget or the assumptions upon which it is based are not reasonable.

    4.26    LIENS.  The Company and its subsidiaries own outright and have good
and marketable title to all of their assets and properties, including, without
limitation, all of the assets and properties reflected on the Balance Sheet, in
each case, except as set forth on Schedule 4.26, free and clear of any lien,
pledge, mortgage, security interest, claim, lease, charge, option, right of
first refusal, easement or any other encumbrance whatsoever (collectively,
"Liens"), except for (i) immaterial assets and properties; (ii) assets and

Except for claims set forth on Schedule 4.27, there are no outstanding unpaid
claims under any such policy or binder.  Neither the Company nor its
subsidiaries has received a notice of cancellation or non-renewal of any such
policy or binder.  Neither the Company nor any Shareholders has any knowledge of
any inaccuracy IN ANY application for such policies or binders, any failure to
pay premiums when due or any similar state of facts which might form the basis
for termination of any such insurance.

    4.28    POTENTIAL CONFLICTS OF INTEREST.  Except as set forth on Schedule
4.28, no officer or director of the Company or its subsidiaries (i) owns,
directly or indirectly, any interest in (excepting not more than 1 % stock

    4.29    ACCOUNTING MATTERS.  None of the Company, its subsidiaries or the
Shareholders has taken or agreed to take any action that would interfere with
Merger Sub and NFO accounting for the business combination to be effected by the
Merger as a "pooling of interests."

    4.30    POOLING LETTER.  The Company has caused the Company's independent
auditors, to deliver to the Company on or prior to the date hereof a draft
letter setting forth the preliminary conclusion of Price Waterhouse LP.  That,
assuming NFO is a corporation eligible to be a party to a transaction seeking
pooling of interests accounting treatment and that the participation of NFO in
the Merger will not, in and of itself, disqualify the Merger from qualifying for
pooling of interests accounting treatment, the Merger will qualify for pooling
of interests accounting treatment if consummated in accordance with this
Agreement, and the Company has delivered a true and complete copy of such letter
to NFO.

    4.31    TOTAL REVENUES OR NET ASSETS.  The Company, together with its
ultimate parent entity (as defined in the Hart-Scott Rodino Antitrust
Improvements Act of 1976, as amended, and the rules promulgated thereunder (the

Act, equal to or in excess of $10 million.

                                     EXHIBIT "C"

                         INDEMNIFICATION AND ESCROW AGREEMENT

         INDEMNIFICATION AND ESCROW AGREEMENT, dated as of April 1, 1997 (the
"Agreement"), by and among NFO RESEARCH, INC., a Delaware corporation ("NFO"),
all of the shareholders of Prognostics, a California corporation
("Prognostics"), who are James B. Wood, The Walter P. Smith Trust (2120186), Jay
H. Friedman and Thomas Rich (collectively, the "Shareholders"), and THE CHASE
MANHATTAN BANK, a New York State Chartered bank, acting as escrow agent (the
"Escrow Agent").

         Pursuant to an Agreement and Plan of Merger, dated as of April 1, 1997
(the "Merger Agreement"), by and among NFO and Prognostics Corp., a Delaware
corporation and wholly-owned subsidiary of NFO (the "Subsidiary"), on the one
hand, and the Shareholders and Prognostics, on the other hand, Prognostics
simultaneously herewith, is merging with the Subsidiary, with the Subsidiary
being the surviving corporation (the "Surviving Company").

         Pursuant to the Merger Agreement, simultaneously herewith, each share
of (i) Non-Voting Common Stock, $.001 par value, of Prognostics (the
"Prognostics Common Stock") and (ii) Preferred Stock, $.001 par value, of
Prognostics (together with the Prognostics Common Stock, the "Prognostics
Stock"), outstanding immediately prior to the date hereof is being converted
into the right to receive the Merger Consideration (as defined in the Merger
Agreement).

         The Merger Agreement provides that at the Effective Time (as defined
in the Merger Agreement) NFO shall deposit with the Escrow Agent hereunder five
percent of the shares of common stock, $.01 par value, of NFO (the "NFO Common
Stock") being issued in the Merger, which the holders of Prognostics Stock would
otherwise be entitled to receive at the Effective Time pursuant to the Merger
Agreement.

         Accordingly, the parties hereto agree as follows:

         1.   SECURITY INTEREST AND ESCROW. To secure the payment of all or at
least a portion of the obligations pursuant to Section 2.1 hereunder (the
"Obligations") for which it is responsible, each Shareholder hereby pledges,
assigns, hypothecates, transfers, sets over and delivers to the Escrow Agent,
and grants to the Escrow Agent, for the benefit of NFO, a first lien on, and
first security interest in, (a) the shares of NFO Common Stock set forth beside
such Shareholders's name in Schedule 1 hereto (together with the proceeds
therefrom), with stock powers duly endorsed in blank for transfer, and (b) all
cash, securities and other property (together with the proceeds therefrom) at
any time and from time to time received, receivable or otherwise distributed or
distributable in exchange for any or all of such shares of NFO Common Stock,
including any shares of stock into which NFO Common Stock shall be reclassified
or otherwise converted, whether pursuant to the terms thereof, by operation of
law or otherwise (all of the foregoing, together with any additional collateral
that may be deposited with the Escrow Agent hereunder, as from time to time
invested and reinvested as provided herein, and all proceeds therefrom, being
hereinafter referred to as the "Escrow Assets"). Each Shareholder hereby agrees
to deposit with the Escrow Agent any cash, securities and other property
referred to in clause (b) of this Section 1 that such Shareholder may acquire,
with stock powers or other


<PAGE>

                                                                               2

instruments of transfer duly endorsed in blank for transfer of any securities or
property so deposited. The Escrow Agent agrees to accept the Escrow Assets, and
to hold them in escrow to secure payment of the Obligations pursuant to the
terms hereof.

         2.   INDEMNIFICATION.

              2.1  OBLIGATIONS TO INDEMNIFY.  Subject to Sections 2.2, 2.3 and
10 hereof:

                   (a)  each Shareholder, severally and not jointly, shall
indemnify and hold harmless NFO and its subsidiaries (including the Surviving
Company) and their respective directors, officers, employees, agents, partners,
affiliates, successors and assigns (collectively, the "Indemnified Persons")
from and against any and all losses, lawsuits, liabilities (including, without
limitation, liability arising under principles of strict or joint and several

pursuant to the Merger Agreement; and

                   (b)  each Shareholder, severally and not jointly, shall
indemnify and hold harmless the Indemnified Persons from and against any and all
Losses based upon, arising out of or otherwise in connection with any inaccuracy
in, or any breach of, any representation, warranty, covenant or agreement of and
pertaining to such Shareholder contained in the Merger Agreement or in any

Section 2.1(a) hereof;

                   (b)  the liability of a Shareholder with respect to each

<PAGE>
                                                                               3

except with respect to a breach of the representation and warranty contained in

which Arthur Andersen LLP delivers to NFO its final audit opinion (the "Audit
Opinion") on the consolidated financial statements of NFO for the fiscal year
ending December 31, 1997;

                   (d)  the Shareholders shall have no liability and no
obligation to indemnify the Indemnified Persons for any Losses pursuant to
Section 2. l(a) hereof, except with respect to a breach of the representation
and warranty contained in (x) Section 4.13(c) of the Merger Agreement as it
relates to the Prognostics Defined Benefit Pension Plan or (y) Section 4.13(e)
of the Merger Agreement as it relates to the Prognostics Automated Data
Processing Prototype 401(k) Plan, unless and until the Shareholders' aggregate
indemnity obligations hereunder with respect to Losses pursuant to Section
2.1(a) hereof shall exceed $50,000 (the "Minimum Amount"), whereupon the
Indemnified Persons shall be entitled to receive the aggregate amount of all
such Losses (including the Minimum Amount);

                   (e)  with respect to any obligation to indemnify the
Indemnified Persons for any Losses pursuant to Section 2.1(a) hereof, after the
Minimum Amount has been met, all amounts payable under Section 2.1(a) (including
the Minimum Amount) shall be payable by the Shareholders until the amounts paid
by the Shareholders pursuant to Section 2.1(a) shall equal $10,000,000, except
that the limitation set forth in this Section 2.2(e) shall not apply with
respect to a breach of a representation and warranty contained in (x) Section

Plan or (y) Section 4.13(e) of the Merger Agreement as it relates to the
Prognostics Automated Data Processing Prototype 401(k) Plan;

                   (f)  during the Escrow Period (as defined in Section 10
hereof) the Indemnified Persons' recourse with respect to recovery of any
amounts payable hereunder or otherwise for Losses shall not be limited to the

                   (g)  the amount of any Loss and the amount of any
indemnification payment to be made by any party shall be determined (i) without
deducting therefrom any tax benefit obtained by reason of deductibility for tax
purposes of any damage, loss or payment giving rise to any such Loss or
indemnification payment and (ii) without including any increase or "gross-up"
for any tax liability that may be incurred by reason of the inclusion in income
of, or by reason of a reduction in tax basis as a result of, any indemnification
payment received hereunder.

              2.3  NOTICE AND OPPORTUNITY TO DEFEND.

                   (a)  Promptly after receipt by any Indemnified Person of
notice of any demand, claim or circumstance which, with the lapse of time, would
or might give rise to


<PAGE>
                                                                               4

a claim or the commencement (or threatened commencement) of any action,
proceeding or investigation (an "Asserted Liability") by any third party that
may result in Losses for which the Shareholders may be required to provide
indemnification pursuant to this Agreement, NFO shall give notice thereof (the
"Claims Notice") to the Shareholders in accordance with Section 14.6 hereof. The
Claims Notice shall describe the Asserted Liability in reasonable detail to the
extent practicable in the circumstances and shall indicate the amount
(estimated, if necessary and to extent feasible) of the Losses that have been or
may be suffered by the Indemnified Person; PROVIDED that the failure to give
such notice shall not relieve the Shareholders of any of their obligations
hereunder (unless such failure directly results in a material increase of their
indemnification obligations hereunder, whereupon the Shareholders shall be
relieved only to the extent of such increase of their indemnification
obligations hereunder).

                   (b)  The Surviving Corporation and NFO jointly shall have
the right to control the defense of any such Asserted Liability with counsel
reasonably satisfactory to the Shareholders. Notwithstanding the foregoing, the
Shareholders may, at their expense, participate in such defense with counsel of
their own choice. In addition, the Shareholders shall, to the extent in the
possession of the Shareholders. make available to NFO and the Surviving
Corporation and their attorneys, accountants and other representatives all
books, records and other information relating to such Asserted Liability and
shall cooperate with NFO and the Surviving Corporation and shall render to them
such assistance as they may reasonably request, at no expense to the
Shareholders, to ensure the proper and adequate defense of such Asserted
Liability. NFO and the Surviving Corporation shall use all reasonable efforts to
mitigate Losses in connection with such Asserted Liability. NFO shall, from time
to time, and as reasonably requested by the Representatives, advise the
Shareholders of the progress of such Asserted Liability.

                   (c)  Neither NFO nor the Surviving Corporation may settle or
compromise any such Asserted Liability without the consent of the
Representatives, which consent shall not be unreasonably withheld, delayed or
conditioned; PROVIDED, HOWEVER, that no consent of the Representatives need be
sought or obtained if (i) the Representatives have contested in writing (or
declined, following NFO's request, to affirm in writing) the obligation of the
Shareholders to indemnify NFO against the Asserted Liability under this
Agreement or (ii) the settlement or compromise of the Asserted Liability
includes a complete release by NFO and the Surviving Corporation of the
Shareholders' indemnification obligations hereunder with respect to the matter
being settled or compromised without giving rise to any indemnification
obligation of the Shareholders pursuant to this Agreement.

of America or any agency or instrumentality thereof;

                                                                               5

                   (b)  certificates of deposit of or accounts with national
banks or corporations endowed with trust powers having capital and surplus in
excess of $100,000,000;

                   (c)  commercial paper at the time of investment rated A-l by
Standard & Poor's Corporation or Prime-l by Moody's Investor's Service, Inc.;
and

                   (d)  obligations issued by any state or municipality of the
United States.

              3.2  ESCROW LEDGER. The Escrow Agent shall maintain with respect
to each of the Shareholders a ledger (the "Escrow Ledger") setting forth (i) all
income or other items added to and distributions from or other items charged
against the Escrow Assets held in such Shareholder's account and (ii) with
respect to any distribution to NFO pursuant to this Agreement, the provision of
this Agreement pursuant to which such distribution has been made.

         4.   REPRESENTATIVES.

              4.1  ATTORNEYS-IN-FACT.  Each Shareholder hereby appoints each of
Walter P. Smith and James B. Wood (the "Representatives") as the
attorney-in-fact of such Shareholder for the purpose of carrying out the
provisions of this Agreement and the Merger Agreement and taking any action and
executing or completing any instruments that the Representatives may deem
necessary or advisable to accomplish the purposes hereof and thereof, which
appointment as attorney-in-fact is irrevocable and coupled with an interest. In
the event either of such persons shall, at any time, be unwilling or unable to
act as such attorney-in-fact, then a replacement for such person shall be
designated by Shareholders holding, at the date of such designation, a majority
of the shares of NFO Common Stock constituting the Escrow Assets at such time
(the "Majority Holders"). NFO shall assume that the individuals referred to
above are acting as attorneys-in-fact, unless it receives written notice signed
by the Majority Holders at the date of such notice that one or more other
attorneys-in-fact have been appointed. All action taken by the Representatives
shall, in order to be effective, be in writing and signed by both of the
Representatives. In addition, NFO shall be entitled to rely upon, and to treat
as duly authorized and approved by the Shareholders and the Representatives, any
and all instructions, directions, letters, paper, documents or other notices
believed by NFO to be genuine and to have been signed by both of the
Representatives.

              4.2  LIABILITY OF REPRESENTATIVES. The duties and obligations of
the Representatives hereunder and under the Merger Agreement shall be determined
solely by the express provisions of this Agreement, and no Representative shall
be under any obligation to refer to any other documents between or among the
parties related in any way to this Agreement, it being specifically understood
that the following provisions are accepted by all of the parties hereto:

                   (a)  no Representative shall be liable to any Shareholder by
reason of any error of judgment or for any mistake of fact or law for anything
that he may do or refrain from doing in connection herewith, unless caused by or
arising out of his own gross negligence or willful misconduct. The Shareholders
shall indemnify and hold the Representatives


<PAGE>

                                                                              6

harmless from and against any and all liability and expense that may arise out
of any action taken or omitted by any of them in accordance with this Agreement,
except such liability and expense as may result from the gross negligence or
willful misconduct of such Representatives; and

                   (b)  the Representatives shall be entitled to rely, and
shall be protected in acting in reliance, upon any instruction or directions
furnished to either Representative in writing signed by a Shareholder pursuant
to any provision of this Agreement and shall be entitled to treat as genuine,
and as the document it purports to be, any letters, paper or other document
furnished to either Representative by a Shareholder, and believed by the
Representatives to be genuine and to have been signed and presented by the
proper party or parties.

         5.   TRANSFER AND OTHER LIENS.  Unless and until the Escrow Assets
have been released from escrow pursuant to Section 6 hereof, no Shareholder
shall sell, dispose of or otherwise transfer its interest in any of the Escrow
Assets or create or permit to exist any lien, security interest or other charge
or encumbrance upon or with respect to any of the Escrow Assets.

         6.   PROCEDURES WITH RESPECT TO CLAIMS.

              6.1  CLAIMS BY NFO. If NFO has a claim for indemnification
against any or all of the Shareholders under Section 2.1 of this Agreement, NFO
shall (to the extent indemnification hereunder is sought) give a Claims Notice
to the Representatives and, if Escrow Assets are being sought by NFO, to the
Escrow Agent, which shall, if appropriate, state the Escrow Assets requested to
be released, the basis upon which such notice is given, and the Shareholder
account(s) from which such Escrow Assets are to be released.

              6.2  RESPONSES BY THE REPRESENTATIVES.  Within 20 days after
receipt of any Claims Notice asserting a claim, the Representatives shall, by
written notice to NFO and, if appropriate, the Escrow Agent, (a) concede
liability in whole or in part or (b) deny liability in whole or in part. Failure
of the Representatives to give such notice within the specified period shall be
deemed a concession of liability in whole.

              6.3  PAYMENT OF CLAIMS. If Escrow Assets are being sought by NFO,
the Escrow Agent shall distribute Escrow Assets to NFO (a) promptly following
any concession of liability, in whole or in part, pursuant to Section 6.2, to
the extent of the liability conceded, (b) promptly following receipt by the
Escrow Agent of, and in accordance with, joint written instructions from NFO and
the Representatives or (c) as determined by a final decision of a court of
competent jurisdiction from which no appeal is then allowed. In the event of a
claim by NFO pursuant to which Escrow Assets are to be distributed, the Escrow
Agent shall distribute Escrow Assets of each Shareholder in accordance with the
terms and provisions of this Agreement; PROVIDED, that the Escrow Agent may only
make distributions on behalf of each Shareholder to satisfy the Losses for which
such Shareholder is responsible to the extent of such Shareholder's portion of
the Escrow Assets, as the same is reduced from time to time by payments to
satisfy Losses for which such Shareholder is responsible for indemnification
pursuant to Sections 2.1(a) and (b). Notwithstanding anything to the contrary
contained herein, the amount of Escrow Assets


<PAGE>

                                                                              7

paid out by the Escrow Agent on behalf of each Shareholder in satisfaction of
Losses for which such Shareholder is responsible shall not exceed the number of
shares of NFO Common Stock originally placed in escrow by such Shareholder (as
the same shall be adjusted for stock splits or other adjustments or increased by
the receipt of other Escrow Assets thereon). For purposes of calculating the
amount of Escrow Assets NFO shall be entitled to receive or, in the case of a
claim for indemnification by NFO that is to be satisfied with Merger
Consideration that is not placed in escrow, such Merger Consideration, each
share of NFO Common Stock, whether or not held in escrow, shall be valued at
$21.15 per share (subject to appropriate adjustment in the event of any
subdivision, combination or other capital adjustment or the payment of a stock
dividend in NFO Common Stock). Escrow Assets to be released to NFO as provided
herein shall be released as follows and in the following order or priority: (i)
FIRST, Escrow Assets consisting of shares of NFO Common Stock shall be released
by delivery to NFO of such shares, together with stock powers or other
instruments of transfer duly executed and (ii) SECOND, Escrow Assets consisting
of cash and all other assets other than shares of NFO Common Stock.

              6.4  INDEMNIFICATION PAYMENTS IN EXCESS OF THE ESCROW ASSETS. If
at any time during the Escrow Period (as defined in Section 10 hereof) the
amount of any payment required to be made by the Escrow Agent to NFO for Losses
pursuant to Section 2. l(a) exceeds the amount of the Escrow Assets, the Escrow
Agent shall distribute to NFO all of the remaining Escrow Assets. If at any time
during the Escrow Period the amount of any payment required to be made by the
Escrow Agent to NFO for Losses pursuant to Section 2.1(b) exceeds the amount of
the Escrow Assets of the Shareholder responsible for indemnification for such
Losses, the Escrow Agent shall distribute to NFO all of the remaining Escrow
Assets of such Shareholder.

         7.   DISTRIBUTION TO THE SHAREHOLDERS FROM THE ESCROW FUND.

              7.1  DISTRIBUTION OF ESCROW FUND TO THE SHAREHOLDERS.  Subject to
the provisions of this Section 7, on the earlier of (i) one year from the
Effective Time (as defined in the Merger Agreement) or (ii) the date on which
Arthur Andersen LLP (or its successor) delivers to NFO the Audit Opinion (the
"Outside Date"), the Escrow Agent shall distribute to each Shareholder out of
such Shareholder's account, to the addresses provided by the Representatives,
the number of shares of NFO Common Stock initially delivered to the Escrow Agent
on behalf of such Shareholder (such number of shares being set forth on Schedule
1 hereto) any Escrow Assets attributable to such shares of Common Stock MINUS
(x) the pro rata (in accordance with the indemnification percentages set forth
on Schedule 1 hereto) portion of such Shareholder's Escrow Assets paid to
satisfy Losses pursuant to Section 2.1(a) of this Agreement and (y) the portion
of such Shareholder's Escrow Assets paid to satisfy the Losses of such
Shareholder pursuant to Section 2.1(b) hereof; PROVIDED, that any distribution
of Escrow Assets pursuant to this Section 7.1 shall be net of all claims made by
NFO pursuant to Section 6 pending against the Escrow Assets on the Outside Date;
PROVIDED, FURTHER, that following the resolution of claims by NFO pending
pursuant to Section 6 on the Outside Date, Escrow Assets, as appropriate, will
be distributed in accordance with this Section 7.1. NFO shall notify the Escrow
Agent and the Representatives of such determination.

              7.2  DISTRIBUTION NOTICE.  The Escrow Agent shall give NFO
written notice (the "Distribution Notice") of any pending distribution pursuant
to Section 7.1. Within 10


<PAGE>

                                                                              8

days after the date of such notice, NFO shall, by written notice to the Escrow
Agent with a copy to the Representatives (a "Distribution Reply"), state (a) its
agreement that the amount specified in the Distribution Notice (or any lesser
portion thereof) is properly distributable to the Shareholders or (b) that it
disputes that the amount is properly distributable to the Shareholders and the
reasons therefor. Failure by NFO to give a Distribution Reply within the
specified period shall be deemed an agreement that the amount specified in the
Distribution Notice is properly distributable to the Shareholders.

              7.3  PAYMENT OF DISTRIBUTIONS.  If NFO gives notice of any
dispute pursuant to Section 7.2, the parties shall attempt to resolve such
dispute as promptly as possible. The Escrow Agent shall make distributions of
the Escrow Assets pursuant to this Section 7 (a) promptly following agreement by
NFO pursuant to Section 7.2 to such distribution, including any portion thereof
as to which NFO does not object, (b) promptly following receipt by the Escrow
Agent of joint written instructions from NFO and the Representatives directing
that such a payment be made to the Shareholders or (c) as determined by a final
decision of a court of competent jurisdiction from which no appeal is then
allowed.

         8.   DISTRIBUTION ON CONSENT.  Notwithstanding the foregoing
provisions, the Escrow Agent shall distribute the Escrow Assets at any time or
from time to time as NFO and the Representatives may, in writing, jointly
direct.

         9.   RIGHTS AS SHAREHOLDER. Except as provided in Sections l(b) and 5
hereof and this Section 9, each Shareholder shall at all times have the right to
exercise all rights of a stockholder with respect to Escrow Assets consisting of
shares of capital stock. Upon delivery of Escrow Assets to NFO pursuant to
Section 6.3 hereof, all rights of each Shareholder to exercise the rights of a
shareholder with respect to such Escrow Assets shall cease.

         10.  TERMINATION OF ESCROW.  The term of the escrow (the "Escrow
Period") hereunder shall terminate upon the distribution of all of the Escrow
Assets held by the Escrow Agent pursuant to this Agreement.

         11.  DUTIES OF ESCROW AGENT.

              11.1    DUTIES LIMITED. The duties and responsibilities of the
Escrow Agent hereunder shall be determined solely by the express provisions of
this Escrow Agreement, and no other or further duties or responsibilities shall
be implied. The Escrow Agent shall not have any liability under, nor duty to
inquire into the terms and provisions of any agreement or instructions, other
than outlined in the Agreement.

              11.2    RELIANCE. The Escrow Agent may rely upon, and shall be
protected in acting or refraining from acting in reliance upon, any written
notice, instruction or request furnished to it hereunder and believed by it to
be genuine and to have been signed or presented by the proper party or parties.
The Escrow Agent shall be under no duty to inquire into or investigate the
validity, accuracy or content of any such document. The Escrow Agent shall have
no duty to solicit any payments which may be due it hereunder.

              11.3    LIABILITY. The Escrow Agent shall not be liable to anyone
whomsoever by reason of any error of judgment or for any mistake of fact or law
for anything that it may do or refrain from doing in connection herewith, unless
caused by or arising out of its own gross negligence or willful misconduct. The
Shareholders, collectively based upon their respective Indemnification
Percentages, and NFO, in an equal amount, shall severally indemnify and hold the
Escrow Agent harmless from and against any and all liability and expense that
may arise out of any action taken or omitted by the Escrow Agent in accordance
with this Agreement, including the costs and expenses incurred in defending any
such claim of liability, except such liability and expense as may result from
the gross negligence or willful misconduct of the Escrow Agent. Anything in this
Agreement to the contrary notwithstanding, in no event shall the Escrow Agent be
liable for special, indirect or consequential loss or damage of any kind
whatsoever (including but not limited to lost profits), even if the Escrow Agent
has been advised of the likelihood of such loss or damage and regardless of the
form of action.

         12.  RESIGNATION: SUCCESSOR ESCROW AGENT.

              12.1    RESIGNATION. The Escrow Agent may resign at any time by
giving 30 days' notice of such resignation to NFO and the Representatives.
Thereafter, the Escrow Agent shall have no further obligation hereunder except
to hold the Escrow Assets as depositary. In such event the Escrow Agent shall
not take any action until NFO and the Representatives have designated a banking
corporation, trust company, attorney or other person as successor escrow agent.
Upon receipt of such instructions, the Escrow Agent shall promptly deliver the
Escrow Assets to such successor escrow agent and shall thereafter have no
further obligations hereunder.

              12.2    TERMINATION. NFO and the Representatives together may
terminate the appointment of the Escrow Agent hereunder upon notice specifying
the date upon which such termination shall take effect. In the event of such
termination, NFO and the Representatives shall within 30 days of such notice
jointly appoint a successor escrow agent and the Escrow Agent shall turn over to
such successor escrow agent all of the Escrow Assets held by it pursuant to this
Agreement. Upon receipt of the Escrow Assets, the successor escrow agent shall
thereupon be bound by all of the provisions hereof.

         13.  FEES AND EXPENSES.  NFO shall (i) pay the Escrow Agent upon
execution of this Agreement reasonable compensation for the services to be
rendered hereunder, as described in Schedule 2 attached hereto, and (ii) pay or
reimburse the Escrow Agent upon request for all expenses, disbursement and
advances, including reasonable attorney's fees, incurred or made by it in
connection with the preparation, execution, performance, delivery modification
and termination of this Agreement.

         14.  MISCELLANEOUS.

              14.1    TIN NUMBER.  Each party hereto, except the Escrow Agent,
shall provide the Escrow Agent with their Tax Identification Number (TIN) as

              14.2    INSTRUCTIONS.

                      (a)    In the event funds transfer instructions are given
(other than in writing at the time of execution of the Agreement), whether in
writing, by telecopier or otherwise, the Escrow Agent is authorized to seek
confirmation of such instructions by telephone call-back to the person or
persons designated on Schedule 3 hereto, and the Escrow Agent may rely upon the
confirmations of anyone purporting to be the person or persons so designated.
The persons and telephone numbers for call-backs may be changed only in writing
actually received and acknowledged by the Escrow Agent. The parties to this
Agreement acknowledge that such security procedure is commercially reasonable.

                      (b)    It is understood that the Escrow Agent and the
beneficiary's bank in any funds transfer may rely solely upon any account
numbers or similar identifying number provided by either of the other parties
hereto to identify (i) the beneficiary, (ii) the beneficiary's bank, or (iii) an
intermediary bank. The Escrow Agent may apply any escrowed funds for any payment
order it executes using any such identifying number, even where its use may
result in a person other than the beneficiary being paid, or the transfer of
funds to a bank other than the beneficiary's bank, or an intermediary bank
designated.

              14.3    NO LIABILITY.  The Escrow Agent shall not incur any
liability for following the instructions herein contained or expressly provided
for, or written instructions given by the parties hereto.

              14.4    UNCERTAINTY. In the event that the Escrow Agent shall be
uncertain as to its duties or rights hereunder or shall receive instructions,
claims or demands from any party hereto which, in its opinion, conflict with any
of the provisions of this Agreement, it shall be entitled to refrain from taking
any action and its sole obligation shall be to keep safely all property held in
escrow until it shall be directed otherwise in writing by all of the other
parties hereto or by a final order or judgment of a court of competent
jurisdiction.

              14.5    MERGER OF ESCROW AGENT. Any corporation into which the
Escrow Agent in its individual capacity may be merged or converted or with which
it may be consolidated, or any corporation resulting from any merger, conversion
or consolidation to which the Escrow Agent in its individual capacity shall be a
party, or any corporation to which substantially all the corporate trust
business of the Escrow Agent in its individual capacity may be transferred,
shall be the Escrow Agent under this Escrow Agreement without further act.

              14.6    NOTICES. All notices and other communication required or
permitted hereunder shall be in writing and shall be delivered personally,
telecopied (and confirmed) or sent by certified, registered or express mail,
postage prepaid. Any such notice shall be deemed given when so delivered
personally, telecopied (and confirmed), or, if mailed, five days (or, in the
case of express mail, one day) after the date of deposit in the United States
mail, as follows:

                            REGISTRATION RIGHTS AGREEMENT


         REGISTRATION RIGHTS AGREEMENT, dated as of April 1, 1997 (the
"Agreement"), by and among NFO RESEARCH, INC., a Delaware corporation (the
"Company"), and JAMES B. WOOD, THE WALTER P. SMITH TRUST (2/20/86), JAY H.
FRIEDMAN and THOMAS RICH, each of whom is receiving common stock of the Company
on the date hereof pursuant to the Merger (as defined below) (collectively, the
"Initial Holders"), and any of their respective (a) successors-in-interest and
(b) family members, trusts and limited partnerships wholly or principally for
the benefit of the Initial Holder and/or family members to whom an Initial
Holder or its successor-in-interest transfers any of the Registrable Securities
(as hereinafter defined) initially issued to such Initial Holder, which family
member, trust or limited partnership described in clause (b) is registered on
the books of the Company (together with the Initial Holders, such
successors-in-interest, family members, trusts and limited partnerships are
hereinafter sometimes referred to as the "Holders").

         This Agreement is made pursuant to the Agreement and Plan of Merger,
dated as of March 20, 1997 (the "Merger Agreement"), by and among the Company,
Prognostics Corp., a Delaware corporation and a wholly owned subsidiary of the
Company (the "Subsidiary"), Prognostics, a California corporation
("Prognostics"), and the Initial Holders, pursuant to which, among other things,
(a) Prognostics is merging with the Subsidiary (the "Merger"), with the
Subsidiary being the surviving corporation and (b) the Company is issuing shares
(the "Shares") of its common stock, par value $.01 per share, to the Initial
Holders, which will not be registered under the Securities Act of 1993, as
amended (the "Securities Act").  In order to induce Prognostics and the Initial
Holders to enter into the Merger Agreement and the Initial Holders to vote in
favor of the Merger, the Company has agreed to provide certain registration
rights with respect to the Shares as set forth in this Agreement.

         In consideration of the mutual covenants and agreements set forth
herein and for good and valuable consideration, the receipt of which is hereby
acknowledged, the parties hereto agree as follows:

         1.   SECURITIES SUBJECT TO THIS AGREEMENT.  The securities entitled to
the benefits of this Agreement are the Shares and any other securities issued by
the Company in exchange for any of the Shares (collectively, the "Registrable
Securities") but, with respect to any particular Registrable Security, only so
long as it continues to be a Registrable Security.  Registrable Securities shall
include any securities issued as a dividend or distribution on account of
Registrable Securities or resulting from a subdivision of the outstanding shares
of Registrable Securities into a greater number of shares (by reclassification,
stock split or otherwise).  For the purposes of this Agreement, a security that
was at one time a Registrable Security shall cease to be a Registrable Security
when (a) such security has been effectively registered under the Securities Act
and has been disposed of pursuant to such registration statement, (b) such
security is distributed to the public pursuant to Rule 144 (or any similar
provision then in force) under the Securities Act, (c) such security has been

<PAGE>

                                                                             2


otherwise transferred and (i) the Company has delivered a new certificate or
other evidence of ownership not bearing the legend set forth on the Shares upon
the initial issuance thereof (or other legend of similar import) and (ii) in the
opinion of counsel to the Company, the subsequent disposition of such security
shall not require the registration or qualification under the Securities Act or
(d) such security has ceased to be outstanding.

         2.   SHELF REGISTRATION.

              (a)     On or prior to August 31, 1997, the Company shall cause
to be filed a registration statement (a "Shelf Registration") on Form S-3 or any
other appropriate form under the Securities Act (including, if necessary, on
Form S-l) for an offering to be made on a delayed or continuous basis pursuant
to Rule 415 thereunder or any similar rule that may be adopted by the Securities
and Exchange Commission (the "Commission") and permitting sales in ordinary
course brokerage or dealer transactions not involving an underwritten public
offering (and shall register or qualify the shares to be sold in such offering
under such other securities or "blue sky" laws as would be required pursuant to
Section 6(d) hereof) covering an amount equal to 22.5% of the Registrable
Securities issued in the Merger and held by each Holder (provided that the
Registrable Securities held in escrow pursuant to the Indemnification and Escrow
Agreement dated the date hereof shall not be so registered).  Prior to the
filing of the Shelf Registration or any supplement or amendment thereto, the
Company will furnish copies of the Shelf Registration or such amendment to one
counsel designated by the Holders of a majority in interest of the Registrable
Shares, and will not file the Shelf Registration or such amendment without the
prior consent of such counsel, which consent shall not be unreasonably withheld.
The Company shall use its reasonable efforts to (a) cause the Shelf Registration
to be declared effective by the Commission as soon as practicable after the date
on which the Company files such registration statement and (b) keep the Shelf
Registration continuously effective (and register or qualify the shares to be
sold in such offering under such other securities or "blue sky" laws as would be
required pursuant to Section 6(d) hereof) for a period beginning on the date on
which the Shelf Registration is declared effective by the Commission and ending
on the first anniversary of the date hereof (or such shorter period that will
terminate when all Registrable Securities covered by the Shelf Registration have
been sold).  The Company agrees, if necessary, to supplement or make amendments
to the Shelf Registration, if required by the registration form used by the
Company for the Shelf Registration or by the instructions applicable to such
registration form or by the Securities Act or the rules or regulations
thereunder or as may reasonably be requested by the Holders of a majority in
interest of the Registrable Securities then outstanding.  Notwithstanding the
foregoing, if the Company shall furnish to the Holders a certificate signed by
the Chief Financial Officer of the Company stating that (i) the Company has
determined, in its good faith judgement, that an amendment or supplement to the
Shelf Registration would interfere with a material financing, acquisition,
corporate reorganization or other material transaction involving the Company or
any of its affiliates and (ii) the need for such an amendment or supplement is
not caused by a proposed public offering of any securities of the Company by any
of its security holders (other than an offering made pursuant to a registration
on Form S-8), the Company may defer such amending or supplementing of such Shelf
Registration for not more

                                                                             3

than 45 days and in such event the Holders shall be required to discontinue
disposition of any Registrable Securities covered by such Shelf Registration
during such period.  Notwithstanding the foregoing, in connection with any
amendment or supplement required to reflect a public offering of securities by
the Company, the Company shall file such amendment or supplement no later than
the same day that it files a registration statement relating to such offering
and shall provide written notice of the filing of such amendment or supplement
to the holders of Registrable Securities promptly following such filing.  The
Company shall pay all Registration Expenses incurred in connection with the
Shelf Registration.

              (b)     At any time after the third anniversary of the date
hereof and prior to the fourth anniversary of the date hereof, any Holder may
make a written request for the Company to cause to be filed a Shelf Registration
on Form S-3 or any other appropriate form under the Securities Act (including,
if necessary, on Form S-1), which filing shall be made as soon as reasonably
practicable following the date of receipt of such written request, for an
offering to be made on a delayed or continuous basis pursuant to Rule 415
thereunder or any similar rule that may be adopted by the Commission and
permitting sales in ordinary course brokerage or dealer transactions not
involving an underwritten public offering (and shall register or qualify the
shares to be sold in such offering under such other securities or "blue sky"
laws as would be required pursuant to Section 6(d) hereof) covering an amount
equal to no more than 20% of the Registrable Securities issued in the Merger and
held by each Holder; PROVIDED, that the Company shall have no obligation under
this Section 2(b) unless Holders that own, in the aggregate, at least 40%
interest of the Registrable Securities then outstanding participate in making
such request.  Prior to the filing of the Shelf Registration or any supplement
or amendment thereto, the Company will furnish copies of the Shelf Registration
or such amendment to one counsel designated by the Holders of a majority in
interest of the Registrable Shares, and will not file the Shelf Registration or
such amendment without the prior consent of such counsel, which consent shall
not be unreasonably withheld.  The Company shall use its reasonable efforts to
(a) cause the Shelf Registration to be declared effective by the Commission as
soon as practicable after the date on which the Company files such registration
statement and (b) keep the Shelf Registration continuously effective (and
register or qualify the shares to be sold in such offering under such other
securities or "blue sky" laws as would be required pursuant to Section 6(d)
hereof) for a period beginning on the date on which the Shelf Registration is
declared effective by the Commission and ending on the fourth anniversary of the
date hereof (or such shorter period that will terminate when all Registrable
Securities covered by the Shelf Registration have been sold); PROVIDED, that if
the Holders are required to discontinue disposition of any Registerable
Securities covered by the Shelf Registration following delivery by the Chief
Financial Officer of the Company of a certificate as specified below, and such
requirement to discontinue disposition occurs during the 90 days preceding the
fourth anniversary of the date hereof, such time period shall be extended by the
length of such discontinuance.  The Company agrees, if necessary, to supplement
or make amendments to the Shelf Registration, if required by the registration
form used by the Company for the Shelf Registration or by the instructions
applicable to such registration form or by the Securities Act or the rules or
regulations thereunder or as may reasonably be requested by

the Holders of a majority in interest of the Registrable Securities then
outstanding.  Notwithstanding the foregoing, if the Company shall furnish to the
Holders a certificate signed by the Chief Financial Officer of the Company
stating that (i) the Company has determined, in its good faith judgement, that
an amendment or supplement to the Shelf Registration would interfere with a
material financing, acquisition, corporate reorganization or other material
transaction involving the Company or any of its affiliates and (ii) the need for
such an amendment or supplement is not caused by a proposed public offering of
any securities of the Company by any of its securityholders (other than an
offering made pursuant to a registration on Form S-8), the Company may defer
such amending or supplementing of such Shelf Registration for not more than 45
days and in such event the Holders shall be required to discontinue disposition
of any Registrable Securities covered by such Shelf Registration during such
period.  Notwithstanding the foregoing, in connection with any amendment or
supplement required to reflect a public offering of securities by the Company,
the Company shall file such amendment or supplement no later than the same day
that it files a registration statement relating to such offering and shall
provide written notice of the filing of such amendment or supplement to the
holders of Registrable Securities promptly following such filing.  The Company
shall pay all Registration Expenses incurred in connection with the Shelf
Registration pursuant to Section 2(b).

              (c)     At any time after the fourth anniversary of the date
hereof and prior to the fifth anniversary of the date hereof, any Holder may
make a written request for the Company to cause to be filed a Shelf Registration
on Form S-3 or any other appropriate form under the Securities Act (including,
if necessary, on Form S-l), which filing shall be made as soon as reasonably
practicable following the date of receipt of such written request, for an
offering to be made on a delayed or continuous basis pursuant to Rule 415
thereunder or any similar rule that may be adopted by the Commission and
permitting sales in ordinary course brokerage or dealer transactions not
involving an underwritten public offering (and shall register or qualify the
shares to be sold in such offering under such other securities or "blue sly"
laws as would be required pursuant to Section 6(d) hereof) covering an amount
equal to no more than 20% of the Registrable Securities issued in the Merger and
held by each Holder; PROVIDED, that the Company shall have no obligation under
this Section 2(c) unless Holders that own, in the aggregate, at least 40%
interest of the Registrable Securities then outstanding participate in making
such request.  Prior to the filing of the Shelf Registration or any supplement
or amendment thereto, the Company will furnish copies of the Shelf Registration
or such amendment to one counsel designated by the Holders of a majority in

such amendment without the prior consent of such counsel, which consent shall

Securities covered by the Shelf

Registration have been sold); PROVIDED, that if the Holders are required to
discontinue disposition of any Registerable Securities covered by the Shelf
Registration following delivery by the Chief Financial Officer of the Company of
a certificate as specified below, and such requirement to discontinue
disposition occurs during the 90 days preceding the fifth anniversary of the
date hereof, such time period shall be extended by the length of such
discontinuance.  The Company agrees, if necessary, to supplement or make
amendments to the Shelf Registration, if required by the registration form used
by the Company for the Shelf Registration or by the instructions applicable to
such registration form or by the Securities Act or the rules or regulations
thereunder or as may reasonably be requested by the Holders of a majority in
interest of the Registrable Securities then outstanding.  Notwithstanding the
foregoing, if the Company shall furnish to the Holders a certificate signed by
the Chief Financial Officer of the Company stating that (i) the Company has
determined, in its good faith judgement, that an amendment or supplement to the
Shelf Registration would interfere with a material financing, acquisition,
corporate reorganization or other material transaction involving the Company or
any of its affiliates and (ii) the need for such an amendment or supplement is
not caused by a proposed public offering of any securities of the Company by any
of its securityholders (other than an offering made pursuant to a registration
on Form S-8), the Company may defer such amending or supplementing of such Shelf
Registration for not more than 45 days and in such event the Holders shall be
required to discontinue disposition of any Registrable Securities covered by
such Shelf Registration during such period.  Notwithstanding the foregoing, in
connection with any amendment or supplement required to reflect a public
offering of securities by the Company, the Company shall file such amendment or
supplement no later than the same day that it files a registration statement
relating to such offering and shall provide written notice of the filing of such
amendment or supplement to the holders of Registrable Securities promptly
following such filing.  The Holders that register Registrable Securities
pursuant to this Section 2(c) shall pay all Registration Expenses incurred in
connection with the Shelf Registration pursuant to Section 2(c).

         3.   DEMAND REGISTRATION.

              3.1     REQUEST FOR REGISTRATION.  At any time after the first
anniversary of the date hereof and prior to the third anniversary of the date
hereof, any Holder may make a written request (specifying the intended method of
disposition) for registration under the Securities Act (a "Demand Registration")
of all or part of such Holder's Registrable Securities; PROVIDED, HOWEVER, that
Holders that own, in the aggregate, a majority in interest of the Registrable
Securities then outstanding must participate in making such request; and
PROVIDED FURTHER, HOWEVER, that, subject to Section 3.5 hereof, the Company
shall not be required to effect more than one Demand Registration pursuant to
this Agreement.  Within ten days after receipt of a request for a Demand
Registration, the Company shall give written notice (the "Notice") of such
request to all other Holders and shall include in such registration all
Registrable Securities that the Company has received written requests for
inclusion therein within 15 days after the Notice is given.  Thereafter, the
Company may elect to include in such registration additional shares of common
stock to be issued by the

<PAGE>

                                                                             6


Company.  All requests made pursuant to this Section 3.1 shall specify the
aggregate number of Registrable Securities to be registered.

              3.2     EFFECTIVE REGISTRATION AND EXPENSES.  A registration
shall not constitute a Demand Registration under Section 3.1 hereof until it has
become effective and, in the case of an offering made on a delayed or continuous
basis pursuant to Rule 415 only, has been effective for at least 120 days.  In
any registration initiated as a Demand Registration, the Company shall pay all
Registration Expenses (as defined in Section 7 hereof) incurred in connection
therewith, whether or not such Demand Registration becomes effective, unless
such Demand Registration fails to become effective as a result OF THE FAULT OF
ONE or more Holders, in which case the Company will not be required to pay the
Registration Expenses incurred with respect to the offering of such Holder's or
Holders' Registrable Securities.  The Registration Expenses incurred with
respect to the offering of such Holder's or Holders' Registrable Securities
shall be the product of (a) the aggregate amount of all Registration Expenses
incurred in connection with such registration and (b) the ratio that the number
of such Registrable Securities bears to the total number of Registrable
Securities included in the registration.

              3.3     PRIORITY ON DEMAND REGISTRATIONS.  The Holder or Holders
making the Demand Registration may elect whether the offering of such
Registrable Securities pursuant to such Demand Registration shall be in the form
of a firm commitment underwritten offering or otherwise; PROVIDED, HOWEVER, that
if the Holders requesting a Demand Registration have specified an underwritten
offering as the intended method of disposition, the Company may elect not to
effectuate such Demand Registration in the form of an underwritten offering if
the market value of the securities to be sold in such Demand Registration is not
equal to or in excess of $10 million; PROVIDED FURTHER, HOWEVER, that the
Company shall not be obligated to keep the Registration Statement for an
offering to be made on a delayed or continuous basis pursuant to Rule 415 under
the Securities Act continuously effective for a period in excess of 120 days
after the date on which the Registration Statement for the Demand Registration
is declared effective by the Commission.  If a Demand Registration is an
underwritten offering and the managing underwriters advise the Company in
writing that in their opinion the number of Registrable Securities and other
securities requested to be included in such offering exceeds the number of
Registrable Securities and other securities, if any, which can be sold in an
orderly manner in such offering within a price range acceptable to the holders
of a majority in interest of the Registrable Securities requesting registration,
the Company will include in such registration prior to the inclusion of any
securities which are not Registrable Securities the number of Registrable
Securities requested to be included which in the opinion of such underwriters
can be sold in an orderly manner within the price range of such offering, pro
rata among the respective holders thereof on the basis of the amount of
Registrable Securities owned by each such holder.

              3.4     SELECTION OF UNDERWRITERS.  Subject to the first proviso
of Section 3.3, if any of the Registrable Securities covered by a Demand
Registration are to be sold in an underwritten offering, the Company shall have
the right to select the investment

<PAGE>

                                                                             7


banker or investment bankers and manager or managers that will underwrite the
offering; PROVIDED, HOWEVER, that such investment bankers and managers must be
reasonably satisfactory to the Holders that own, in the aggregate, a majority in
interest of the Registrable Securities that the Company has been requested to
register.

              3.5     LIMITATIONS, CONDITIONS AND QUALIFICATIONS TO OBLIGATIONS
UNDER SECTION 3 REGISTRATION COVENANTS.  The Company shall be entitled to
postpone for a reasonable period of time (but not exceeding 90 days) the filing
of any registration statement otherwise required to be prepared and filed by it
pursuant to Section 3.1 if the Company determines, in its good faith judgment,
that such registration and offering would interfere with any material financing,
acquisition, corporate reorganization or other material transaction involving
the Company or any of its affiliates and promptly gives the holders of
Registrable Securities requesting registration thereof pursuant to Section 3.1
written notice of such determination, containing a general statement of the
reasons for such postponement and an approximation of the anticipated delay;
PROVIDED, that such right to postpone the filing of a registration statement to
be prepared and filed by the Company pursuant to Section 3.1 can only be
exercised by the Company not more than once in any one-year period.  If the
Company shall so postpone the filing of a registration statement, holders of
Registrable Securities requesting registration thereof pursuant to Section 3.1,
representing not less than 50% of the Registrable Securities with respect to
which registration has been requested, shall have the right to withdraw the
request for registration by giving written notice to the Company within 15 days
after receipt of the notice of postponement and, in the event of such
withdrawal, such request shall not be counted for purposes of the requests for
registration to which holders of Registrable Securities are entitled pursuant to
Section 3.1 hereof.

         4.   PIGGYBACK REGISTRATION.  At any time after the first anniversary
of the date hereof and prior to the third anniversary of the date hereof,
whenever the Company proposes to file a registration statement under the
Securities Act with respect to an underwritten public offering of common stock
by the Company, the Company shall give written notice (the "Offering Notice") of
such proposed filing to each of the Holders at least 20 days before the
anticipated filing date.  Such Offering Notice shall offer all such Holders the
opportunity to register such number of Registrable Securities as each such
Holder may request in writing, which request for registration (each, a
"Piggyback Registration") must be received by the Company within 15 days after
the Offering Notice is given.  If a Piggyback Registration is an underwritten
primary registration on behalf of the Company, and the managing underwriters
advise the Company in writing that in their opinion the number of securities
requested to be included in such registration exceeds the number which can be
sold in such offering without adversely affecting the marketability of the
offering, the Company will include in such registration (i) first, the
securities the Company proposes to sell, (ii) second, the securities requested
to be included in such registration pursuant to the Primary Registration
Agreement (as defined in Section 11.1) and the MK Registration Agreement (as
defined in Section 11.1), (iii) third, the Registrable Securities requested to
be included in such registration, pro rata among the holders of such Registrable
Securities on the basis of the number of shares owned by each such holder, and
(iv) fourth, other securities requested to be included in such registration.  If
a Piggyback Registration is an underwritten secondary


<PAGE>

                                                                             8

registration on behalf of holders of the Company's securities, and the managing
underwriters advise the Company in writing that in their opinion the number of
securities requested to be included in such registration exceeds the number
which can be sold in such offering without adversely affecting the marketability
of the offering, the Company will include in such registration (i) first, the
securities requested to be included therein pursuant to the Primary Registration
Agreement and the MK Registration Agreement, (ii) second, the securities
requested to be included therein by the holders of Registrable Securities, pro
rata among the holders of Registrable Securities on the basis of the number of
securities so requested to be included therein owned by each such holder, and
(iii) third, other securities requested to be included in such registration.

         5.   RESTRICTIONS ON PUBLIC SALE BY HOLDERS OF REGISTRABLE SECURITIES.
Each Holder agrees, if reasonably requested by the managing underwAter or
underwriters for any underwritten offing covered by any Demand Registration or
Piggyback Registration (whether or not such Holder is participating therein),
not to effect any public sale or distribution of Registrable Securities,
including a sale pursuant to Rule 144 (or any similar provision then in force)
under the Securities Act, during the 14 days prior to, and during the 180-day
period beginning on, the effective date of such Demand Registration or Piggyback
Registration (except as part of such underwritten offering).

         6.   REGISTRATION PROCEDURES.  Whenever the Holders have requested
that any Registrable Securities be registered pursuant to Section 3 or 4 hereof,
the Company shall use its reasonable efforts to effect the registration of
Registrable Securities in accordance with the intended method of disposition
thereof as expeditiously as practicable and, in connection with any such
request, the Company shall as expeditiously as possible:

              (a)     in connection with a request pursuant to Section 3
hereof, prepare and file with the Commission, not later than 120 days, after
receipt of a request to file a registration statement with respect to
Registrable Securities, a registration statement on any form for which the
Company then qualifies or which counsel for the Company shall deem appropriate
and which form shall be available for the sale of such Registrable Securities in
accordance with the intended method of distribution thereof and, if the offing
is an underwritten offering, shall be reasonably satisfactory to the managing
underwriter or underwriters, and use its best efforts to cause such registration
statement to become effective; PROVIDED, HOWEVER, that before filing a
registration statement or prospectus or any amendments or supplements thereto,
the Company shall (i) furnish to the counsel selected by the Holder or Holders
making the demand, if any, or, if no demand, by the Holders that own, in the
aggregate, a majority in interest of the Registrable Securities covered by such
registration statement, copies of all such documents proposed to be filed, which
documents shall not be filed without the consent of such counsel, which consent
shall not be unreasonably withheld, and (ii) notify such counsel and each seller
or prospective seller of Registrable Securities of any stop order issued or
threatened by the Commission and take all reasonable actions required to prevent
the entry of such stop order or to remove it if entered;

<PAGE>

                                                                             9

              (b)     in connection with a registration pursuant to Section 3
hereof, prepare and file with the Commission such amendments and supplements to
such registration statement and the prospectus used in connection therewith as
may be necessary to keep such registration statement effective for a period of
not less than 120 days (or such shorter period that will terminate when all
Registrable Securities covered by such registration statement have been sold,
but not before the expiration of the applicable period referred to in Section
4(3) of the Securities Act and Rule 174 thereunder, if applicable); PROVIDED,
HOWEVER, that prior to the filing of such supplement or amendment, the Company
will furnish copies thereof to the Holders, any underwriters and counsel for the
Holders and will not file such supplement or amendment without the prior consent
of such counsel, which consent shall not be unreasonably withheld, and comply
with the provisions of the Securities Act applicable to it with respect to the
disposition of all securities covered by such registration statement during such
period in accordance with the intended method of disposition by the sellers
thereof set forth in such registration statement or as may reasonably be
requested by the Holders of a majority of the Registrable Securities then
outstanding;

              (c)     furnish to each seller of Registrable Securities such
number of copies of the registration statement, each amendment and supplement
thereto (in each case including all exhibits thereto), the prospectus included
in such registration statement (including each preliminary prospectus) and such
other documents as each seller may reasonably request in order to facilitate the
disposition of the Registrable Securities owned by such seller;

              (d)     use reasonable efforts to register or qualify such
Registrable Securities under such other securities or "blue sky" laws of such
jurisdictions as any seller or underwriter reasonably requests in writing and to
do any and all other acts and things that may be reasonably necessary or
advisable to register or qualify for sale in such jurisdictions the Registrable
Securities owned by such seller; PROVIDED, HOWEVER, that the Company shall not
be required to (i) qualify generally to do business in any jurisdiction where it
is not then so qualified, (ii) subject itself to taxation in any such
jurisdiction, (iii) consent to general service of process in any such
jurisdiction or (iv) make any change in its charter or by-laws that the Board of
Directors of the Company determines in good faith to be contrary to the best
interest of the Company and its stockholders;

              (e)     use reasonable efforts to cause the Registrable
Securities covered by such registration statement to be registered with or
approved by such other governmental agencies or authorities as may be necessary
by virtue of the business and operations of the Company to enable the seller or
sellers thereof or the underwriters, if any, to consummate the disposition of
such Registrable Securities;

              (f)     notify each seller of such Registrable Securities at any
time when a prospectus relating thereto is required to be delivered under the
Securities Act of the happening of any event as a result of which the prospectus
included in such registration statement contains an untrue statement of a
material fact or omits to state any material fact required to be stated therein
or necessary to make the statements therein, in light of the

<PAGE>

                                                                            10

circumstances under which they were made, not misleading, and prepare and file
with the Commission a supplement or amendment to such prospectus so that, as
thereafter delivered to the purchasers of such Registrable Securities, such
prospectus will not contain an untrue statement of a material fact or omit to
state any material fact required to be stated therein or necessary to make the
statements therein, in light of the circumstances under which they were made,
not misleading, PROVIDED that prior to the filing of such supplement or
amendment, the Company will furnish copies thereof to the Holders, any
underwriters and counsel for the Holders and will not file such supplement or
amendment without the prior consent of such counsel, which consent shall not be
unreasonably withheld;

              (g)     enter into customary agreements (including an
underwriting agreement in customary form, if the offering is an underwritten
offering) and take such other actions as are reasonably required in order to
expedite or facilitate the disposition of such Registrable Securities;

              (h)     make available for inspection by any seller of
Registrable Securities, any underwriter participating in any disposition
pursuant to such registration statement, the counsel referred to in clause (i)
of Section 6(a) hereof and any attorney, accountant or other agent retained by
any such seller or underwriter (collectively, the "Inspectors"), all financial
and other records, pertinent corporate documents and properties of the Company
(collectively, the "Records") as shall be reasonably necessary to enable them to
exercise their due diligence responsibility, and cause the Company's officers,
directors, employees and agents to supply all information reasonably requested
by any such Inspector in connection with such registration statement.  Records
that the Company determines, in good faith, to be confidential and that it
notifies the Inspectors are confidential shall not be disclosed by the
Inspectors unless (i) the disclosure of such Records is, in the reasonable
judgment of any Inspector, necessary to avoid or correct a misstatement or
omission of a material fact in the registration statement or (ii) the release of
such Records is ordered pursuant to a subpoena or other order from a court or
governmental agency of competent jurisdiction or required (in the written
opinion of counsel to such seller or underwriter, which counsel shall be
reasonably acceptable to the Company) pursuant to applicable state or federal
law.  Each seller of Registrable Securities agrees that it will, upon learning
that disclosure of such Records are sought by a court or governmental agency,
give notice to the Company and allow the Company, at the Company's expense, to
undertake appropriate action to prevent disclosure of the Records deemed
confidential;

              (i)     if such sale is pursuant to an underwritten offering, use
reasonable efforts to obtain a "cold comfort" letter and updates thereof from
the Company's independent public accountants in customary form and covering such
matters of the type customarily covered by "cold comfort" letters as the
managing underwriter or underwriters reasonably request;

              (j)     otherwise use reasonable efforts to comply with all
applicable rules and regulations of the Commission, and make generally available
to its security holders, as soon as reasonably practicable, an earnings
statement covering a period of 12

<PAGE>

                                                                            11

months, beginning within three months after the effective date of the
registration statement, which earnings statement shall satisfy the provisions of
Section 1 l(a) of the Securities Act; and

              (k)     use reasonable efforts to cause all Registrable
Securities covered by the registration statement to be listed on each securities
exchange or market, if any, on which similar securities issued by the Company
are then listed, provided that the applicable listing requirements are
satisfied.

         The Company may require each seller or prospective seller of
Registrable Securities as to which any registration is being effected to furnish
to the Company such information regarding the distribution of such securities
and other matters as may be required to be included in the registration
statement.

         Each holder of Registrable Securities agrees that, upon receipt of any
notice from the Company of the happening of any event of the kind described in
paragraph (f) of this Section 6, such holder shall forthwith discontinue
disposition of Registrable Securities pursuant to the registration statement
covering such Registrable Securities until such holder's receipt of the copies
of the supplemented or amended prospectus contemplated by paragraph (f) of this
Section 6 and, if so directed by the Company, such holder shall deliver to the
Company (at the Company's expense) all copies, other than permanent file copies
then in such holder's possession, of the prospectus covering such Registrable
Securities current at the time of receipt of such notice.  If the Company shall
give any such notice, the Company shall extend the period during which such
registration statement shall be maintained effective pursuant to this Agreement
(including the period referred to in paragraph (b) of this Section 6) by the
number of days during the period from and including the date of the giving of
such notice pursuant to paragraph (f) of this Section 6 to and including the
date when each seller of Registrable Securities covered by such registration
statement shall have received the copies of the supplemented or amended
prospectus contemplated by paragraph (f) of this Section 6.  Notwithstanding
anything to the contrary set forth above in this paragraph, the Company agrees
that it may not require the holders of Registrable Securities to discontinue
disposition of Registrable Securities for purposes of effecting a public
offering of any securities of the Company by any of its securityholders (other
than an offering made pursuant to a registration on Form S-8).  Notwithstanding
the foregoing, if the Company shall furnish to the Holders a certificate signed
by the Chief Financial Officer of the Company stating that (i) the Company has
determined, in its good faith judgement, that an amendment or supplement to the
Shelf Registration would interfere with a material financing, acquisition,
corporate reorganization or other material transaction involving the Company or
any of its affiliates and (ii) the need for such an amendment or supplement is
not caused by a proposed secondary public offering of securities of the Company
by any of its securityholders (other than an offering made pursuant to a
registration on Form S-8), the Company may defer such amending or supplementing
of such Shelf Registration for not more than 45 days and in such event the
Holders shall be required to discontinue disposition of any Registrable
Securities covered by such Shelf Registration during such period.
Notwithstanding the foregoing, in connection with any amendment or supplement
required to reflect a public offering of securities by the

<PAGE>

                                                                            12

Company, the Company shall file such amendment or supplement no later than the
same day that it files a registration statement relating to such offering and
shall provide written notice of the filing of such amendment or supplement to
the holders of Registrable Securities promptly following such filing.

         7.   REGISTRATION EXPENSES.  The Company or the Holders, as specified
in this Agreement, shall pay all expenses incident to its performance of or
compliance with this Agreement, regardless of whether such registration becomes
effective including, without limitation, (a) all Commission, stock exchange or
market and National Association of Securities Dealers, Inc. registration and
filing fees, (b) all fees and expenses incurred in complying with securities or
"blue sky" laws (including reasonable fees and disbursements of counsel in
connection with "blue sky" qualifications of the Registrable Securities), (c)
all printing, messenger and delivery expenses, (d) all fees and disbursements of
the Company's independent public accountants and counsel, (e) all fees and
expenses of any special experts retained by the Company in connection with any
Demand Registration or Piggyback Registration pursuant to the terms of this
Agreement, and (f) the fees and disbursements of one counsel retained
collectively by the Holders, to the extent such fees and disbursements do not
exceed an aggregate of $10,000 for a registration; PROVIDED, HOWEVER, that the
Company shall not pay (x) any Registration Expenses incurred pursuant to Section
2(c) of this Agreement or (y) the costs and expenses of any Holder relating to
underwriters' commissions and discounts relating to Registrable Securities to be
sold by such Holder, brokerage fees, transfer taxes or, except as provided in
clause (f) of this Section 7, the fees or expenses of any counsel, accountants
or other representatives retained by the Holders, individually or in the
aggregate.  All of the expenses described in this Section 7 that are to be paid
by the Company or the Holders, as the case may be, are herein called
"Registration Expenses."

         8.   INDEMNIFICATION: CONTRIBUTION.

              8.1     INDEMNIFICATION BY THE COMPANY.  The Company agrees to
indemnify, to the fullest extent permitted by law, each Holder, its officers,
directors and agents and each person, if any, who controls such Holder (within
the meaning of the Securities Act), against any and all losses, claims, damages,
liabilities and expenses caused by any untrue or alleged untrue statement of
material fact contained in any registration statement, prospectus or preliminary
prospectus or any amendment thereof or supplement thereto or any omission or
alleged omission to state therein a material fact required to be stated therein
or necessary to make the statements therein (in the case of a prospectus, in
light of the circumstances under which they were made) not misleading, except
insofar as the same are caused by or contained in any information with respect
to such Holder furnished in writing to the Company by such Holder expressly for
use therein or by such Holder's failure to deliver a copy of the prospectus or
any supplements thereto after the Company has furnished such Holder with a
sufficient number of copies of the same or by the delivery of prospectuses by
such Holder after the Company notified such Holder in writing to discontinue
delivery of prospectuses.  The Company also shall indemnify any underwriters of
the Registrable Securities, their officers and directors and each person who
controls such

<PAGE>

                                                                            13

underwriters (within the meaning of the Securities Act) to the same extent as
provided above with respect to the indemnification of the Holders.

              8.2     INDEMNIFICATION BY HOLDERS.  In connection with any
registration statement in which a Holder is participating, each such Holder
shall furnish to the Company in writing such information and affidavits with
respect to such Holder as the Company reasonably requests for use in connection
with any such registration statement or prospectus and agrees to indemnify,
severally and not jointly, to the fullest extent permitted by law, the Company,
its officers, directors and agents and each person, if any, who controls the
Company (within the meaning of the Securities Act) against any and all losses,
claims, damages, liabilities and expenses resulting from any untrue or alleged
untrue statement of a material fact or any omission or alleged omission of a
material fact required to be stated in any registration statement, prospectus or
preliminary prospectus or any amendment thereof or supplement thereto or
necessary to make the statements therein (in the case of a prospectus, in light
of the circumstances under which they were made) not misleading, to the extent,
but only to the extent, that such untrue or alleged untrue statement or omission
is contained in or improperly omitted from, as the case may be, any information
or affidavit with respect to such Holder so furnished in writing by such Holder;
PROVIDED, HOWEVER, that the obligations of each Holder under this Section 8.2
shall be limited to an amount equal to the proceeds to each Holder of
Registrable Securities sold in connection with such registration.  Each Holder
also shall indemnify any underwriters of the Registrable Securities, their
officers and directors and each person who controls such underwriters (within
the meaning of the Securities Act) to the same extent as provided above with
respect to the indemnification of the Company.

              8.3     CONDUCT OF INDEMNIFICATION PROCEEDINGS.  Any party that
proposes to assert the right to be indemnified under this Section 8 shall,
promptly after receipt of notice of commencement of any action against such
party in respect of which a claim is to be made against an indemnifying party or
parties under this Section 8, notify each such indemnifying party of the
commencement of such action, enclosing a copy of all papers served, but the
omission so to notify such indemnifying party will not relieve it from any
liability that it may have to any indemnified party under the foregoing
provisions of this Section 8 unless, and only to the extent that, such omission
results in the forfeiture of substantive rights or defenses by the indemnifying
party.  If any such action is brought against any indemnified party and it
notifies the indemnifying party of its commencement, the indemnifying party will
be entitled to participate in and, to the extent that it elects by delivering
written notice to the indemnified party promptly after receiving notice of the
commencement of the action from the indemnified party, jointly with any other
indemnifying party similarly notified, to assume the defense of the action, with
counsel reasonably satisfactory to the indemnified party, and after notice from
the indemnifying party to the indemnified party of its election to assume the
defense, the indemnifying party will not be liable to the indemnified party for
any legal or other expenses except as provided below and except for the
reasonable costs of investigation subsequently incurred by the indemnified party
in connection with the defense.  If the indemnifying party assumes the defense,
the indemnifying party shall have the right to settle such action without the
consent of the

<PAGE>

                                                                            14

indemnified party; PROVIDED, HOWEVER, that the indemnifying party shall be
required to obtain such consent (which consent shall not be unreasonably
withheld) if the settlement includes any admission of wrongdoing on the part of
the indemnified party or any decree or restriction on the indemnified party or
its officers or directors; PROVIDED, FURTHER, that no indemnifying party, in the
defense of any such action, shall, except with the consent of the indemnified
party (which consent shall not be unreasonably withheld), consent to entry of
any judgment or enter into any settlement that does not include as an
unconditional term thereof the giving by the claimant or plaintiff to such
indemnified party of a release from all liability with respect to such action.
The indemnified party will have the right to employ its own counsel in any such
action, but the fees, expenses and other charges of such counsel will be at the
expense of such indemnified party unless (a) the employment of counsel by the
indemnified party has been authorized in writing by the indemnifying party, (b)
the indemnified party has reasonably concluded (based on advice of counsel) that
there may be legal defenses available to it or other indemnified parties that
are different from or in addition to those available to the indemnifying party,
(c) a conflict or potential conflict exists (based on advice of counsel to the
indemnified party) between the indemnified party and the indemnifying party (in
which case the indemnifying party will not have the right to direct the defense
of such action on behalf of the indemnified party) or (d) the indemnifying party
has not in fact employed counsel to assume the defense of such action within a
reasonable time after receiving notice of the commencement of the action, in
each of which cases the reasonable fees, disbursements and other charges of
counsel will be at the expense of the indemnifying party or parties.  It is
understood that the indemnifying party or parties shall not, in connection with
any proceeding or related proceedings in the same jurisdiction, be liable for
the reasonable fees, disbursements and other charges of more than one separate
firm admitted to practice in such jurisdiction at any one time from all such
indemnified party or parties unless (x) the employment of more than one counsel
has been authorized in writing by the indemnifying party or parties, (y) an
indemnified party has reasonably concluded (based on advice of counsel) that
there may be legal defenses available to it that are different from or in
addition to those available to the other indemnified parties or (z) a conflict
or potential conflict exists (based on advice of counsel to an indemnified
party) between such indemnified party and the other indemnified parties, in each
of which cases the indemnifying party shall be obligated to pay the reasonable
fees and expenses of such additional counsel or counsels.  An indemnifying party
will not be liable for any settlement of any action or claim effected without
its written consent (which consent shall not be unreasonably withheld).

              8.4     CONTRIBUTION.  If the indemnification provided for in
this Section 8 from the indemnifying party is unavailable to an indemnified
party hereunder in respect of any losses, claims, damages, liabilities or
expenses referred to herein, then the indemnifying party, to the extent such
indemnification is unavailable, in lieu of indemnifying such indemnified party,
shall contribute to the amount paid or payable by such indemnified party as a
result of such losses, claims, damages, liabilities or expenses in such
proportion as is appropriate to reflect the relative fault of the indemnifying
party and indemnified parties in connection with the actions that resulted in
such losses, claims, damages, liabilities or expenses.  The relative fault of
such indemnifying party and indemnified parties shall be determined by reference
to, among other things, whether any action in question, including

<PAGE>

                                                                            15

any untrue or alleged untrue statement of a material fact or omission or alleged
omission to state a material fact, has been made by, or relates to information
supplied by, such indemnifying party or indemnified parties, and the parties'
relative intent, knowledge, access to information and opportunity to correct or
prevent such action.  The amount paid or payable by a panty as a result of the
losses, claims, damages, liabilities and expenses referred to above shall be
deemed to include, subject to the limitations set forth in Section 8.3 hereof,
any legal or other fees or expenses reasonably incurred by such party in
connection with any investigation or proceeding; PROVIDED, HOWEVER, that no
Holder will be required to contribute pursuant to this Section 8.4 any amount in
excess of the proceeds to it of all Registrable Securities sold by it pursuant
to such registration.

              The parties hereto agree that it would not be just and equitable
if contribution pursuant to this Section 8.4 were determined by PRO RATA
allocation or by any other method of allocation that does not take account of
the equitable considerations referred to in the immediately preceding paragraph.
No person guilty of fraudulent misrepresentation (within the meaning of Section
1 l(f) of the Securities Act) shall be entitled to contribution from any person.

              If indemnification is available under this Section 8, the
indemnifying parties shall indemnify each indemnified party to the full extent
provided in Sections 8.1 and 8.2 hereof without regard to the relative fault of
said indemnifying parties or indemnified party.

         9.   PARTICIPATION IN UNDERWRITTEN REGISTRATIONS.  No person may
participate in any underwritten registration hereunder unless such person (a)
agrees to sell such person's securities on the basis provided in any
underwriting agreements approved by the persons entitled hereunder to approve
such arrangements and (b) completes and executes all questionnaires, powers of
attorney, indemnities, underwriting agreements and other documents reasonably
required under the terms of such underwriting arrangements.

         10.  RULE 144.  The Company covenants that it shall use its best
efforts to file the reports required to be filed by it under the Securities
Exchange Act of 1934, as amended, and the rules and regulations of the

interest, or his estate.

Mr. Wood is no longer employed by Prognostics because of retirement, voluntary
termination, or termination by Prognostics with cause, or without cause as 
covered in 5.02 of the Employment Agreement, Prognostics and Walter Smith 
shall have the right, exercisable within 60 days, to purchase all or any part 
of the shares owned by Mr. Wood. The option shall be exercisable first by 
Prognostics and thereafter by Walter Smith, at the price and on the terms 
provided in this Agreement, and in the manner provided by Article 6 of this 
Agreement.

Wood in contravention of any covenant of good faith and fair dealing, expressed
or implied, in employment law as applied in the State of California.

perform his employment duties, Prognostics shall purchase all shares owned by
Mr. Wood at the price and on the terms provided in the Agreement.

    For purposes of this paragraph, "disability" shall be defined in accordance
with the terms of any disability insurance policy on Mr. Wood that is owned by
Prognostics at the time of the onset of the disability. In the absence of such a
disability insurance policy, "disability" shall mean inability to perform all or
substantially all his regular duties as contemplated by his employment with
Prognostics.

    In the event Prognostics and Mr. Wood, or his personal representative, fail

arbitrator, and the two arbitrators so selected shall settle the issue. If the
arbitrators cannot agree, they shall designate a third arbitrator to reach a
decision. The arbitrators shall be entitled to receive and rely on any medical
advice or other advice that they shall deem required to enable them to make a
decision under this paragraph, and their decision shall be final and binding on
Prognostics and Mr. Wood.

    If Mr. Wood should die after becoming disabled, but before the actual sale
of his shares, then the purchase and sale of his shares will be treated as the
purchase and sale of a decedent's shares under paragraph 4.03 of this Agreement.

    4.03 PURCHASE ON DEATH.  Within a period beginning with the death of Mr.
Wood and ending 60 days after his death, his estate shall sell and Prognostics
shall purchase and redeem all of Mr. Wood's shares of Prognostics' stock, at the
price and on the terms provided in the Agreement.

    The term "estate" as used in this Article shall mean and include as those
terms are understood in California law:

    (a)  The duly appointed and qualified executor, executrix, administrator,
administratrix, administrator with the will annexed, or administratrix with the
will annexed of the estate of the Mr. Wood.

    (b)  Any other person who may, because of the community property or other
law of any jurisdiction, acquire without formal probate proceedings any right,
title, or interest in or to the shares owned by Mr. Wood in the Corporation by
reason of the death of Mr. Wood.

    The estate of Mr. Wood shall bear, and save Prognostics harmless from, all
costs and expenses required for securing any court orders, court decrees, court
approvals, inheritance tax clearances, and estate tax clearances required to
enable the estate of Mr. Wood to transfer to Prognostics, or Walter Smith, full
legal and equitable tax-free title to the shares of Mr. Wood in Prognostics.

    The death of Mr. Wood's spouse, for purposes of this Article, shall not be
considered a death requiring the purchase by Prognostics, from the estate of his
deceased spouse, any shares owned by Mr. Wood by way of operation of testate,
intestate or community property law or other estate planning instrument, such as
a trust or will executed by his deceased spouse, which requests the disposition
of any purported interest in such stock to any person other than Mr. Wood.

    4.04 OPTIONAL PURCHASE ON OTHER EVENTS.  In the event Mr. Wood is
adjudicated a bankrupt (voluntarily or involuntarily), or makes an assignment
for the benefit of creditors, or files a petition seeking to

Prognostics and J.B. Wood

force the involuntary winding up and dissolution of Prognostics under
Corporations Code section 1800, or if substantially all property of the Mr. Wood
is levied on and sold in a judicial proceeding, Prognostics and Walter Smith
shall have the right to purchase all or any part, of the shares owned by Mr.
Wood. If at any time Mr. Wood has information that would reasonably cause him to
believe that his shares would be transferred involuntarily or by operation of
law, he shall give written notice to Prognostics and Walter Smith in accordance
with paragraph 10.04 "Notice".

    4.05 DEATH OR TOTAL INCAPACITY.  Upon the death or total incapacity as
defined under 4.02 above (but not retirement) of Walter Smith, Mr. Wood shall
have the right, as defined under 3.05 above, to make an offer to purchase all or
a portion of the stock of Prognostics from the estate of Mr. Smith, if within
six months of the time of the above stated event another offer is received for
the purchase of all or a portion of the stock in Prognostics.

    4.06 GIFTS BY MR. SMITH TO OTHERS.  In the event that Mr. Smith wishes to
give any portion of his preferred or common stock to another individual(s), that
individual(s) shall take subject to the rights and obligations imposed by this
agreement. The new individual(s) shall be bound by this Buy-Sell Agreement in
the same manner and capacity as Mr. Smith would be bound were he the owner of
the shares.

ARTICLE 5. VALUATION

                                   AND PROGNOSTICS

$40,000       Menlo Park, California                          December 19, 1994


    In installments as hereinafter state, for value received, I promise to pay
to Prognostics at its Headquarters Office in Menlo Park, California, the sum of
$40,000, with interest on unpaid principal at the rate of eight (8) percent per
annum from date hereof until paid, said interest payable quarterly and principal
and interest payable in lawful money of the United State of America. Said
principal sum shall be due and payable in one installment of $40,000 at the end
of the term of this note which is four (4) years commencing on December 19, 1994
and continuing until December 19, 1998.  This note is renewable and may be
extended for successive terms, or any portion thereof, at the sole discretion of
Prognostics without notice to or consent of the undersigned.

    As the sole collateral and security for this promissory note I hereby
pledge my interest in all shares of non-voting Common Stock of Prognostics owned
by me.  Concurrently with the execution of this Promissory Note I will endorse a
stock assignment form(s) assigning my entire interest in my shares of non-voting
Common Stock of Prognostics.  I will turn over this assignment form(s), along

the secretary of the Corporation for Deposit.  This note is a non-recourse note
secured solely by the stock mentioned in the first sentence of this paragraph.

    Upon default in payment of any such installment of interest when due, the
whole of the principal sum then remaining unpaid and all interest accrued hereon
shall, at the option of the holder hereof, become immediately due and payable,
with 30 days notice of demand.  In case any payment herein provided for shall
not be made at maturity, or if suit be brought to enforce payment of this Note,
I further promise to pay all costs of enforcement, and collection including
reasonable attorneys' fees.  I further waive presentment, notice of non-payment,
notice of dishonor, protest, demand, and diligence.

    IN WITNESS WHEREOF, this Note is executed as of the day and year first
written above.

                                  BUY-SELL AGREEMENT
                                 BETWEEN PROGNOSTICS 
                                    AND J.B. WOOD


    The Buy-Sell Agreement ("Agreement") originally executed on December 19,
1994 at Palo Alto, California, between J. B. Wood ("Mr. Wood") and Prognostics,
a California Corporation, ("Prognostics") with respect to shares of Prognostics'
common stock is hereby Amended ("Amendment") as follows: 

ARTICLE 1. RECITALS

    Whereas, Prognostics wishes to maintain the approximate ownership of Mr.
Wood in the total percentage of the common stock outstanding; and 

    Whereas, Mr. Wood and Prognostics believe such an Amendment to the current
Buy-Sell Agreement to be in their best interests. 

    Therefore, in consideration of the mutual covenants and conditions
contained in the original Buy-Sell Agreement executed on December 19, 1994 and
contained herein as an Amendment to the original document, Prognostics and Mr.
Wood agree as follows:

ARTICLE 2. INCREASE IN NUMBER OF SHARES

    2.01  ADDITIONAL SHARES ISSUED.  Additional non-voting common shares may
be issued to Mr. Wood after the execution of this Amendment.  The total number
of non-voting common shares which may be issued as a result of this Amendment is

ARTICLE 3.  EXECUTION OF COMPLIMENTARY DOCUMENTS

    3.01  COMPLIMENTARY DOCUMENTS TO BE CONTEMPORANEOUSLY EXECUTED. 
Contemporaneously with the execution of this Amendment, additional documents,
including but not limited to a promissory note, pledge agreement and spousal
consent, shall be executed by and between Mr. Wood and Prognostics prior to the
formal issuance of the stock certificates which evidence ownership in any
non-voting common stock of Prognostics.

ARTICLE 4.  PROVISIONS IN BUY-SELL AGREEMENT STILL IN EFFECT

    4.01  ALL PROVISIONS OF DOCUMENT EXECUTED DECEMBER 19, 1994 ARE IN EFFECT. 
The execution of this Amendment shall serve solely to supplement the provisions
of the original Buy-Sell Agreement which was executed on December 19, 1994. 
Nothing in this Amendment shall serve to cancel a provision or to render the
original document ineffective or expired, in whole or in part, except where
specifically noted in 4.02 below. 

    4.02  AMENDMENT(S) TO SPECIFIC PROVISIONS.  The following provisions of
the original Buy-Sell Agreement, dated December 19, 1994, are Amended as
follows: 

          7.02     CERTIFICATE LEGEND.  Each share certificate, whether
presently owned or subsequently issued, shall have conspicuously endorsed on its
face the following words; "Sale, transfer, encumbrance, or disposition of the
shares represented by this certificate is restricted by the provisions of a
Buy-Sell Agreement between Mr. Wood and Prognostics dated December 19, 1994 as
amended August 31, 1995.  All provisions of the Buy-Sell Agreement and Amendment
are incorporated by reference in this certificate.  A copy of the Agreement and
Amendment may be inspected at the principal office of Prognostics."   A copy of
this Agreement and Amendment shall be delivered to the secretary of Prognostics
and shall be shown only in case of necessity to individuals, (i.e., auditors,
potential buyers of Prognostics, etc.), inquiring about them.

          7.05     PARTICIPATION OF OTHER INDIVIDUALS.  It is anticipated that
other individuals will be invited to purchase stock in Prognostics and nothing
in this agreement shall prohibit the sale of these additional shares.  The
additional sales shall be allocated either from the authorized Preferred or
non-voting Common shares.  The appraisal value listed for all subsequent shares
issued shall be the same as that listed under Article 5 of this   agreement. 
Therefore, the value of each share of currently issued stock will be diluted in
proportion to the number of new shares subsequently issued.  For example, if
additional shares are issued, or series is authorized, from the non-voting
Common shares, then the equity interest each Shareholder holds, in the value of
Prognostics attributable to their non-voting Common stock, shall be diluted in
proportion to their current holdings as related to the total number of shares
issued for all series within the non-voting Common Stock.

pledge my interest in all shares of non-voting Common Stock of Prognostics owned
by me.  Concurrently with the execution of this Promissory Note I will endorse a
stock assignment form(s) assigning my entire interest in my shares of non-voting
Common Stock of Prognostics.  I will turn over this assignment form(s), along
with my stock certificate(s) for the non-voting Common Stock of Prognostics, to
the secretary of the Corporation for Deposit.  This note is a non-recourse note
secured solely by the stock mentioned in the first sentence of this paragraph. 

    Upon default in payment of any such installment of interest when due, the
whole of the principal sum then remaining unpaid and all interest accrued hereon
shall, at the option of the holder hereof, become immediately due and payable,
with 30 days notice of demand.  In case any payment herein provided for shall
not be made at maturity, or if suit be brought to enforce payment of this Note,
I further promise to pay all costs of   enforcement, and collection including
reasonable attorneys' fees.  I further waive presentment, notice of non-payment,
notice of dishonor, protest, demand, and diligence. 

    IN WITNESS WHEREOF, this Note is executed as of the day and year first

    I acknowledge that I have read the foregoing First Amendment to Buy-Sell
Agreement and additional Promissory Note, and that I know and understand the
contents therein contained in each.  I am aware that by the provisions of these
documents, my spouse agrees to hold his shares of stock ("Shares") of

Shares, including my interest in them, upon certain events.  I hereby approve
the provisions of each document and consent to such sale; and I agree that I

therein during my lifetime except as expressly permitted by these documents. 
Upon my death, I agree that I will not make any transfer of, or otherwise deal
with, my interest in the Shares, whether by bequest or by the application of the
residuary clause of my Will or otherwise, in any manner that would have the
effect of causing the Shares to cease being subject to these documents.

                                     EXHIBIT "H"


    PLEDGE AGREEMENT dated as of April 4, 1997, made by the undersigned (the
"Pledgor") in favor of Fleet National Bank (the "Bank").

PRELIMINARY STATEMENTS:

    (1)  The Bank has made a loan to the pledgor in the original principal
amount of $240,000 (the "Loan"), as evidenced by a Time Promissory Note dated as
of even date herewith (said Time Promissory Note, as it may hereafter be amended
or otherwise modified from time to time, being the "Note," the terms defined
therein and not otherwise defined herein being used herein as therein defined)
made by the Pledgor in favor of the Bank.

    (2)  The Pledgor is the owner of the shares (the "Pledged Shares") of stock
described in Schedule I hereto and issued by the corporations named therein.

    (3)  It is a condition precedent to the making of the Loan by the Bank, as
evidenced by the Note, that the Pledgor shall have made the pledge contemplated
by this Agreement.

    NOW, THEREFORE, in consideration of the premises and in order to induce the
Bank to make the Loan evidenced by the Note, the Pledgor hereby agrees with the
Bank as follows:

    SECTION 1.     PLEDGE. The Pledgor hereby pledges to the Bank, and grants
to the Bank a security interest in, the following (the "Pledged Collateral"):

         (a)       the Pledged Shares and the certificates representing the
Pledged Shares, and all dividends, cash, instruments and other property from
time to time received, receivable or otherwise distributed in respect of or in
exchange for any or all of the Pledged Shares; and

         (b)       all proceeds of any and all of the foregoing Collateral
(including, without limitation, proceeds that constitute property of the types
described above).

    SECTION 2.     SECURITY FOR OBLIGATIONS. This Agreement secures the payment
of all obligations of the Pledgor now or hereafter existing under the Note and
the other Facility Documents, whether for principal, interest, fees, expenses or
otherwise, and all obligations of the Pledgor now or hereafter existing under
this Agreement (all such obligations of the Pledgor being the "Obligations").
Without limiting the generality of the foregoing, this Agreement secures the
payment of all amounts which constitute part of the Obligations and would be
owed by the Pledgor to the Bank under the Note and the other Facility Documents
but for the fact that they are unenforceable or not allowable due to the
existence of a bankruptcy, reorganization or similar proceeding involving the
Pledgor.  Notwithstanding anything to the contrary contained in this Agreement,
the Note or any other Facility Document, the Bank's sole recourse against the
Pledgor hereunder, whether for principal, interest, fees or other charges or
claims, shall be limited to the Bank's rights and remedies with respect to the
Pledged Collateral.

    SECTION 3.     DELIVERY OF PLEDGED COLLATERAL. All certificates or
instruments representing or evidencing the Pledged Collateral shall be delivered
to and held by or on behalf of the Bank pursuant hereto and shall be in suitable
form for transfer by delivery, or shall be accompanied by duly executed
instruments of transfer or assignment in blank, all in form and substance
satisfactory to the Bank. The Bank shall have the right, at any time in its
discretion and without notice to the Pledgor, to transfer to or to register in
the name of the Bank or any of its nominees any or all of the Pledged
Collateral, subject only to the revocable rights specified in Section 6(a).

                                                                               2


In addition, the Bank shall have the right at any time to exchange certificates
or instruments representing or evidencing Pledged Collateral for certificates or
instruments of smaller or larger denominations

    SECTION 4.     REPRESENTATIONS AND WARRANTIES. Except as set forth in
Schedule 4, the Pledgor represents and warrants as follows:

         (a)       The Pledged Shares have been duly authorized and validly
issued and are fully paid and non-assessable.

         (b)       The Pledgor is the legal and beneficial owner of the Pledged
Collateral free and clear of any lien, security interest, option or other charge
or encumbrance except for the security interest created by this Agreement and
except for the security interest in the Pledged Collateral held by Prognostics
Corp. by virtue of (i) a Pledge and Assignment of Stock Certificate issued
pursuant to a certain Buy-Sell Agreement made by the Pledgor in favor of
Prognostics, a California corporation, dated as of December 19, 1994, as amended
on August 31, 1995 (the "Buy-Sell Agreement"), securing the Pledgor's
obligations under a Promissory Note dated as of December 19, 1994, in the
original principal amount of $40,000 by the Pledgor in favor of Prognostics and
(ii) a Pledge and Assignment of Stock Certificate issued pursuant to the
Buy-Sell Agreement, securing the Pledgor's obligations under a Promissory Note
dated as of August 31, 1995, in the original principal amount of $3,460 by the
Pledgor in favor of Prognostics. Prognostics Corp. has succeeded to the
interests of Prognostics under said Pledge Agreements and said Promissory Notes.

         (c)       The pledge of the Pledged Shares pursuant to this Agreement
creates a valid and perfected first priority security interest in the Pledged
Collateral (subject to the prior pledge in favor of Prognostics Corp. pursuant
to the Pledge Agreements referred to in subsection (b) above), securing the
payment of the Obligations.

         (d)       No consent of any other person or entity and no
authorization, approval, or other action by, and no notice to or filing with,
any governmental authority or regulatory body is required (i) for the pledge by
the Pledgor of the Pledged Collateral pursuant to this Agreement or for the
execution, delivery or performance of this Agreement by the Pledgor, (ii) for
the perfection or maintenance of the security interest created hereby or (iii)
for the exercise by the Bank of the voting or other rights provided for in this
Agreement or the remedies in respect of the Pledged Collateral pursuant to this
Agreement (except as may be required in connection with any disposition of any
portion of the Pledged Collateral by laws affecting the offering and sale of
securities generally).

         (e)       There are no conditions precedent to the effectiveness of
this Agreement that have not been satisfied or waived.

         (f)       The Pledgor has, independently and without reliance upon the
Bank and based on such documents and information as he has deemed appropriate,
made his own credit analysis and decision to enter into this Agreement.

    SECTION 5.     FURTHER ASSURANCES. The Pledgor agrees that at any time and
from time to time, at the expense of the Pledgor, the Pledgor will promptly
execute and deliver all further instruments and documents, and take all further
action, that may be necessary or desirable, or that the Bank may reasonably
request, in order to perfect and protect any Pledged Collateral interest granted
or purported to be granted hereby or to enable the Bank to exercise and enforce
its rights and remedies hereunder with respect to any Pledged Collateral. On the
request of the Bank, the Pledgor shall execute and deliver or cause to be
executed and delivered to the Bank such documents and instruments respecting the
Pledged Collateral as may be necessary for the Bank to perfect its


<PAGE>

                                                                               3


interests in the Pledged Collateral or to enforce its rights hereunder,
including, without limitation, any documents, opinions and affidavits that the
Bank may reasonably request from time to time to obtain the transfer, and to
assure itself or the transferability, of the Pledged Collateral without legend
or "stop transfer" instructions. The Pledgor hereby irrevocably appoints the
Bank as his attorney-in-fact and proxy, with full authority in the place and
stead of the Pledgor and in the name of the Pledgor or otherwise, from time to
time in the Bank's discretion after the occurrence of an Event of Default (as
hereinafter defined), to take any action and to execute and file any instrument
(including, without limitation, one or more stock powers, other instruments of
transfer and/or notices on SEC Form 144) that the Bank may deem necessary or
advisable to accomplish the foregoing and the purposes of this Agreement, which
appointment is coupled with an interest (and the Pledgor will, on request of the
Bank, provide to the Bank all information which the Bank may request in order to
complete such instruments).

    SECTION 6.     VOTING RIGHTS; DIVIDENDS; ETC. 


         (a)       So long as no event of default set forth in the Note (an
"Event of Default") shall have occurred and be continuing:

                   (i) The Pledgor shall be entitled to exercise or refrain
from exercising any and all voting and other consensual rights pertaining to the
Pledged Collateral or any part thereof for any purpose not inconsistent with the
terms of this Agreement or the Note; PROVIDED, HOWEVER, that the Pledgor shall
not exercise or refrain from exercising any such right if, in the Bank's
judgment, such action would have a material adverse effect on the value of the
Pledged Collateral or any part thereof, and, PROVIDED, FURTHER, that the Pledgor
shall give the Bank at least five days' written notice of the manner in which he
intends to exercise, or the reasons for refraining from exercising, any such
right.

                   (ii) The Pledgor shall be entitled to receive and retain any
and all dividends paid in respect of the Pledged Collateral, PROVIDED, HOWEVER,
that any and all

                        (A) dividends paid or payable other than in cash in
respect of, and instruments and other property received, receivable or otherwise
distributed in respect of, or in exchange for, any Pledged Collateral,

                        (B) dividends and other distributions paid or payable
in cash in respect of any Pledged Collateral in connection with a partial or
total liquidation or dissolution or in connection with a reduction of capital,
capital surplus or paid-in-surplus, and

                        (C) cash paid, payable or otherwise distributed in
respect of principal of, or in redemption of, or in exchange for, any Pledged
Collateral,

shall be, and shall be forthwith delivered to the Bank to hold as, Pledged
Collateral and shall, if received by the Pledgor, be received in trust for the
benefit of the Bank, be segregated from the other property or funds of the
Pledgor, and be forthwith delivered to the Bank as Pledged Collateral in the
same form as so received (with any necessary endorsement or assignment).

                   (iii) The Bank shall execute and deliver (or cause to be
executed and delivered) to the Pledgor all such proxies and other instruments as
the Pledgor may reasonably request for the purpose of enabling the Pledgor to
exercise the voting and other rights which he is entitled to exercise pursuant
to paragraph (i) above and to receive the dividends which he is authorized to
receive and retain pursuant to paragraph (ii) above.

                                                                               4


         (b)       Upon the occurrence and during the continuance of an Event
of Default:

                   (i) All rights of the Pledgor to exercise or refrain from
exercising the voting and other consensual rights which he would otherwise be
entitled to exercise pursuant to Section 6(a)(i) and to receive the dividends
which he would otherwise be authorized to receive and retain pursuant to Section
6(a)(ii) shall cease, and all such rights shall thereupon become vested in the
Bank who shall thereupon have the sole right to exercise or refrain from
exercising such voting and other consensual rights and to receive and hold as
Pledged Collateral such dividends.

                   (ii) All dividends which are received by the Pledgor
contrary to the provisions of paragraph (i) of this Section 6(b) shall be
received in trust for the benefit of the Bank, shall be segregated from other
funds of the Pledgor and shall be forthwith paid over to the Bank as Pledged
Collateral in the same form as so received (with any necessary endorsement).

    SECTION 7.     TRANSFERS AND OTHER LIENS. The Pledgor agrees that he will
not (i) sell, assign (by operation of law or otherwise) or otherwise dispose of,
or grant any option with respect to, any of the Pledged Collateral, or (ii)
create or permit to exist any lien, security interest, option or other charge or
encumbrance upon or with respect to any of the Pledged Collateral, except for
the security interest under this Agreement and the pledge in favor of
Prognostics Corp. pursuant to the Pledge Agreements referred to in subsection
4(b) above).

    SECTION 8.     BANK APPOINTED ATTORNEY-IN-FACT. The Pledgor hereby appoints
the Bank the Pledgor's attorney-in-fact, with full authority in the place and
stead of the Pledgor and in the name of the Pledgor or otherwise, from time to
time in the Bank's discretion to take any action and to execute any instrument
which the Bank may deem necessary or advisable to accomplish the purposes of
this Agreement (subject to the rights of the Pledgor under Section 6),
including, without limitation, to receive, endorse and collect all instruments
made payable to the Pledgor representing any dividend or other distribution in
respect of the Pledged Collateral or any part thereof and to give full discharge
for the same.  

    SECTION 9.     BANK MAY PERFORM. If the Pledgor fails to perform any
agreement contained herein, the Bank may itself perform, or cause performance
of; such agreement, and the expenses of the Bank incurred in connection
therewith shall be payable by the Pledgor under Section 13.

    SECTION 10.    THE BANK'S DUTIES. The powers conferred on the Bank
hereunder are solely to protect its interest in the Pledged Collateral and shall
not impose any duty upon it to exercise any such powers. Except for the safe
custody of any Pledged Collateral in its possession and the accounting for
moneys actually received by it hereunder, the Bank shall have no duty as to any
Pledged Collateral, as to ascertaining or taking action with respect to calls,
conversions, exchanges, maturities, tenders or other matters relative to any
Pledged Collateral, whether or not the Bank has or is deemed to have knowledge
of such matters, or as to the taking of any necessary steps to preserve rights
against any parties or any other rights pertaining to any Pledged Collateral.
The Bank shall be deemed to have exercised reasonable care in the custody and
preservation of the Pledged Collateral in its possession if the Pledged
Collateral is accorded treatment substantially equal to that which the Bank
accords its own property.

    SECTION 11.    REMEDIES UPON DEFAULT. If an Event of Default shall have
occurred and be continuing:

         (a)       The Bank may exercise in respect of the Pledged Collateral,
in addition to other rights and remedies provided for herein or otherwise
available to it, all the rights and remedies of a secured party in default under
the Uniform Commercial Code in effect in the State of Connecticut at that time
(the "Code") (whether or not the Code applies to the affected Collateral), and
may also, without notice except as specified


<PAGE>

                                                                               5


below, sell the Pledged Collateral or any part thereof in one or more parcels at
public or private sale, at any exchange, broker's board or at any of the Bank's
offices or elsewhere, for cash, on credit or for future delivery, and upon such
other terms as the Bank may deem commercially reasonable. The Pledgor agrees
that, to the extent notice of sale shall be required by law, at least ten days
notice to the Pledgor of the time and place of any public sale or the time after
which any private sale is to be made shall constitute reasonable notification.
The Bank shall not be obligated to make any sale of Pledged Collateral
regardless of notice of sale having been given. The Bank may adjourn any public
or private sale from time to time by announcement at the time and place fixed
therefor, and such sale may, without further notice, be made at the time and
place to which it was so adjourned.

         (b)       Any cash held by the Bank as Pledged Collateral and all cash
proceeds received by the Bank in respect of any sale of, collection from, or
other realization upon all or any part of the Pledged Collateral may, in the
discretion of the Bank, be held by the Bank as collateral for, and/or then or at
any time thereafter be applied (after payment of any amounts payable to the Bank
pursuant to Section 13) in whole or in part by the Bank against, all or any part
of the Obligations in such order as the Bank shall elect. Any surplus of such
cash or cash proceeds held by the Bank and remaining after payment in full of
all the Obligations shall be paid over to the Pledgor or to whomsoever may be
lawfully entitled to receive such surplus.

         (c)       The Pledgor recognizes that the Bank may not effect an
immediate public sale of any or all securities held as Pledged Collateral and
may elect to sell the Pledged Collateral over a period of time and/or resort to
one or more public or private sales thereof, which may result in prices, and be
on other terms, less favorable to the Pledgor than if such sale were immediately
made in a public sale. If, at the time of sale, the Bank determines that there
may be a question as to whether the Pledged Collateral may be sold under Section
4(1) of the Securities Act of 1933, as amended (the "Securities Act") without
restriction, the Bank, in its sole discretion at any such sale, may restrict the
prospective bidders or purchasers as to their number, nature and investment
intention (including, without limitation, requiring that the persons making such
purchases represent and agree, to the satisfaction of the Bank, that they meet
such criteria and are purchasing the securities for their own account, for
investment and not with a view toward the distribution or resale of any thereof
in violation of the Securities Act). The Bank may also sell such Pledged
Collateral from time to time in limited quantities over a period of time and in
transactions limited to "brokers' transactions" if needed to comply with Rule
144 promulgated under the Securities Act ("Rule 144"). Any sale may be made in
one lot, as an entirety or in separate parcels, even if such sale is made at a
discount from the then current market price of the securities and regardless of
the availability of Section 4(1) of the Securities Act (without compliance with
the restrictions under Rule 144), paragraph (k) of Rule 144 or another exemption
from the registration provisions of the Securities Act or registration under the
Securities Act.

    SECTION 12.    PLEDGOR'S COOPERATION. If the Bank shall determine to
exercise its right to sell all or any of the Pledged Collateral pursuant to
Section 11, the Pledgor agrees that, upon request of the Bank, the Pledgor will,
at his own expense, do or cause to be done all such acts and things as may be
necessary to make such sale of the Pledged Collateral or any part thereof valid
and binding and in compliance with applicable law.

    SECTION 13.    EXPENSES. The Pledgor will upon demand pay to the Bank the
amount of any and all reasonable expenses, including, the reasonable fees and
expenses of its counsel and of any experts and agents, which the Bank may incur
in connection with the failure by the Pledgor to perform or observe any of the
provisions hereof This Section is subject to the non-recourse provisions
contained in the Note

    SECTION 14.    AMENDMENTS, ETC. No amendment or waiver of any provision of
this Agreement, and no consent to any departure by the Pledgor herefrom, shall
in any event be effective unless the same shall be in writing and signed by the
Bank, and then such waiver or consent shall be effective only in the specific
instance and for the specific purpose for which given.

    SECTION 15.    ADDRESSES FOR NOTICES. All notices and other communications
provided for hereunder shall be sent in the manner set forth in the Note and to
the addresses set forth in the Note

    SECTION 16.    CONTINUING SECURITY INTEREST; ASSIGNMENTS UNDER NOTE. This
Agreement shall create a continuing security interest in the Pledged Collateral
and shall (i) remain in full force and effect until the payment in full of the
Obligations and all other amounts payable under this Agreement, (ii) be binding
upon the Pledgor, his successors and assigns, and (iii) inure, together with the
rights and remedies of the Bank hereunder, to the benefit of, and be enforceable
by, the Bank and its successors, transferees and assigns. Without limiting the
generality of the foregoing clause (iii), the Bank may assign or otherwise
transfer all or any portion of its rights and obligations under the Note
(including, without limitation, all or any portion of the Loan owing to it) to
any other person or entity, and such other person or entity shall thereupon
become vested with all the benefits in respect thereof granted to the Bank
herein or otherwise. Upon the later of payment in full of the Obligations and
all other amounts payable under this Agreement, the security interest granted
hereby shall terminate and all rights to the Pledged Collateral shall revert to
the Pledgor. Upon any such termination, the Bank will, at the Pledgor's expense,
return to the Pledgor such of the Pledged Collateral as shall not have been sold
or otherwise applied pursuant to the terms hereof and execute and deliver to the
Pledgor such documents as the Pledgor shall reasonably request to evidence such
termination.

    SECTION 17.    GOVERNING LAW; TERMS. This Agreement shall be governed by,
and construed in accordance with, the laws of the State of Connecticut, except
as required by mandatory provisions of law and except to the extent that the
validity or perfection of the security interest hereunder, or remedies
hereunder, in respect of any particular Pledged Collateral are governed by the
laws of a jurisdiction other than the State of Connecticut. Unless otherwise
defined herein or in the Note, terms defined in Article 9 of the Code are used
herein as therein defined

Agreement as of the date first above written.

                                     EXHIBIT "I"


    PLEDGE AGREEMENT dated as of April 4, 1997, made by the undersigned (the
"Pledgor") in favor of Fleet National Bank (the "Bank"). 


PRELIMINARY STATEMENTS:

    (1)  The Bank has made a loan to the Pledgor in the original principal
amount of $360,000 (the "Loan"), as evidenced by a Time Promissory Note dated as
of even date herewith (said Time Promissory Note, as it may hereafter be amended
or otherwise modified from time to time, being the "Note," the terms defined
therein and not otherwise defined herein being used herein as therein defined)
made by the Pledgor in favor of the Bank. 

    (2)  The Pledgor is the owner of the shares (the "Pledged Shares") of stock
described in Schedule I hereto and issued by the corporations named therein. 

    (3)  It is a condition precedent to the making of the Loan by the Bank, as  
evidenced by the Note, that the Pledgor shall have made the pledge contemplated
by this Agreement. 

    NOW, THEREFORE, in consideration of the premises and in order to induce the
Bank to make the Loan evidenced by the Note, the Pledgor hereby agrees with the
Bank as follows: 

    SECTION 1.     PLEDGE. The Pledgor hereby pledges to the Bank, and grants
to the Bank a security interest in, the following (the "Pledged Collateral"): 

         (a)  the Pledged Shares and the certificates representing the Pledged
Shares, and all dividends, cash, instruments and other property from time to
time received, receivable or otherwise distributed in respect of or in exchange
for any or all of the Pledged Shares; and 

         (b)  all proceeds of any and all of the foregoing Collateral
(including, without limitation, proceeds that constitute property of the types
described above). 

    SECTION 2.     SECURITY FOR OBLIGATIONS. This Agreement secures the payment
of all obligations of the Pledgor now or hereafter existing under the Note and
the other Facility Documents, whether for principal, interest, fees, expenses or
otherwise, and all obligations of the Pledgor now or hereafter existing under
this Agreement (all such obligations of the Pledgor being the "Obligations"). 
Without limiting the generality of the  foregoing, this Agreement secures the
payment of all amounts which constitute part of the Obligations and would be
owed by the Pledgor to the Bank under the Note and the other Facility Documents
but for the fact that they are unenforceable or not allowable due to the
existence of a bankruptcy, reorganization or similar proceeding involving the
Pledgor.  Notwithstanding anything to the contrary contained in this Agreement,
the Note or any other Facility Document, the Bank's sole recourse against the
Pledgor hereunder, whether for principal, interest, fees or other charges or
claims, shall be limited to the Bank's rights and remedies with respect to the
Pledged Collateral. 

    SECTION 3.     DELIVERY OF PLEDGED COLLATERAL.  All certificates or
instruments representing or evidencing the Pledged Collateral shall be delivered
to and held by or on behalf of the Bank pursuant hereto and shall be in suitable
form for transfer by delivery, or shall be accompanied by duly executed
instruments of transfer or assignment in blank, all in form and substance
satisfactory to the Bank.  The Bank shall have the right, at any time in its
discretion and without notice to the Pledgor, to transfer to or to register in
the name of the Bank or any of its nominees any or all of the Pledged
Collateral, subject only to the revocable rights specified in 

<PAGE>

Section 6(a).  In addition, the Bank shall have the right at any time to
exchange certificates or instruments representing or evidencing Pledged
Collateral for certificates or instruments of smaller or larger denominations.

    SECTION 4.     REPRESENTATIONS AND WARRANTIES.  Except as set forth in
Schedule 4, the Pledgor represents and warrants as follows: 

         (a)  The Pledged Shares have been duly authorized and validly issued
and are fully paid and non-assessable. 

         (b)  The Pledgor is the legal and beneficial owner of the Pledged
Collateral free and clear of any lien, security interest, option or other charge
or encumbrance except for the security interest created by this Agreement. 

         (c)  The pledge of the Pledged Shares pursuant to this Agreement
creates a valid and perfected first priority security interest in the Pledged
Collateral, securing the payment of the Obligations. 
 
         (d)  No consent of any other person or entity and no authorization,
approval, or other action by, and no notice to or filing with, any governmental
authority or regulatory body is required (i) for the pledge by the Pledgor of
the Pledged Collateral pursuant to this Agreement or for the execution, delivery
or performance of this Agreement by the Pledgor, (ii) for the perfection or
maintenance of the security interest created hereby or (iii) for the exercise by
the Bank of the voting or other  rights provided for in this Agreement or the
remedies in respect of the Pledged Collateral pursuant to this Agreement (except
as may be required in connection with any disposition of any portion of the
Pledged Collateral by laws affecting the offering and sale of securities
generally). 

         (e)  There are no conditions precedent to the effectiveness of this
Agreement that have not been satisfied or waived.

         (f)  The Pledgor has, independently and without reliance upon the Bank
and based on such documents and information as he has deemed appropriate, made
his own credit analysis and decision to enter into this Agreement. 

    SECTION 5.     FURTHER ASSURANCES.  The Pledgor agrees that at any time and
from time to time, at the expense of the Pledgor, the Pledgor will promptly
execute and deliver all further instruments and documents, and take all further
action, that may be necessary or desirable, or that the Bank may reasonably
request, in order to perfect and protect any Pledged Collateral interest granted
or purported to be granted hereby or to enable the Bank to exercise and enforce
its rights and remedies hereunder with respect to any Pledged Collateral.  On
the request of the Bank, the Pledgor shall execute and deliver or cause to be
executed and delivered to the Bank such documents and instruments respecting the
Pledged Collateral as may be necessary for the Bank to perfect its interests in
the Pledged Collateral or to enforce its rights hereunder, including, without
limitation, any documents, opinions and affidavits that the Bank may reasonably
request from time to time to obtain the transfer, and to assure itself or the
transferability, of the Pledged Collateral without legend or "stop transfer"
instructions.  The Pledgor hereby irrevocably appoints the Bank as his
attorney-in-fact and proxy, with full authority in the place and stead of the
Pledgor and in the name of the Pledgor or otherwise, from time to time in the
Bank's discretion after the occurrence of an Event of Default (as hereinafter
defined), to take any action and to execute and file any instrument (including,
without limitation, one or more stock powers, other instruments of transfer
and/or notices on SEC Form 144) that the Bank may deem necessary or advisable to
accomplish the foregoing and the purposes 

<PAGE>

of this Agreement, which appointment is coupled with an interest (and the
Pledgor will, on  request of the Bank, provide to the Bank all information which
the Bank may request in order to complete such instruments). 

    SECTION 6.     VOTING RIGHTS; DIVIDENDS; ETC. 

         (a)  So long as no event of default set forth in the Note (an "Event
of Default") shall have occurred and be continuing: 

              (i)  The Pledgor shall be entitled to exercise or refrain from
exercising any and all voting and other consensual rights pertaining to the
Pledged Collateral or any part thereof for any purpose not inconsistent with the
terms of this Agreement or the Note; PROVIDED, HOWEVER, that the Pledgor shall
not exercise or  refrain from exercising any such right if, in the Bank's
judgment,  such action would have a material adverse effect on the value of the
Pledged Collateral or any part thereof, and, PROVIDED, FURTHER, that the Pledgor
shall give the Bank at least five days' written notice of the manner in which he
intends to exercise, or the reasons for remaining from exercising, any such
right. 

              (ii) The Pledgor shall be entitled to receive and retain any and
all dividends paid in respect of the Pledged Collateral, PROVIDED, HOWEVER, that
any and all 
 
                   (A)  dividends paid or payable other than in cash in respect
of, and instruments and other property received, receivable or otherwise
distributed in respect of, or in exchange for, any Pledged Collateral, 

                   (B)  dividends and other distributions paid or payable in
cash in respect of any Pledged Collateral in connection with a partial or total
liquidation or dissolution or in connection with a reduction of capital, capital
surplus or paid-in-surplus, and 

                   (C)  cash paid, payable or otherwise distributed in respect
of principal of, or in redemption of, or in exchange for, any Pledged
Collateral, shall be, and shall be forthwith delivered to the Bank to hold as,
Pledged Collateral and shall, if received by the Pledgor, be received in trust
for the benefit of the Bank, be segregated from the other property or funds of
the Pledgor, and be forthwith delivered to the Bank as Pledged Collateral in the
same form as so received (with any necessary endorsement or assignment). 

              (iii)  The Bank shall execute and deliver (or cause to be
executed and delivered) to the Pledgor all such proxies and other instruments as
the Pledgor may reasonably request for the purpose of enabling the Pledgor to
exercise the voting and other rights which he is entitled to exercise pursuant
to paragraph (i) above and to receive the dividends which he is authorized to
receive and retain pursuant to paragraph (ii) above. 

         (b)  Upon the occurrence and during the continuance of an Event of a
default. 

              (i)  All rights of the Pledgor to exercise or refrain from
exercising the voting and other consensual rights which he would otherwise be
entitled to exercise pursuant to Section 6(a)(i) and to receive the dividends
which he would otherwise be authorized to receive and retain pursuant to Section
6(a)(ii) shall cease, and all such rights shall thereupon become vested in the
Bank who shall thereupon have the sole right to exercise or refrain from
exercising such voting and other consensual rights and to receive and hold as
Pledged Collateral such dividends. 

<PAGE>

              (ii)  All dividends which are received by the Pledgor contrary to
the provisions of paragraph (i) of this Section 6(b) shall be received in trust
for the benefit of the Bank, shall be segregated from other funds of the Pledgor
and shall be forthwith paid over to the Bank as Pledged Collateral in the same
form as so received (with any necessary endorsement). 

    SECTION 7.     TRANSFERS AND OTHER LIENS.  The Pledgor agrees that he will
not (i) sell, assign (by operation of law or otherwise) or otherwise dispose of,
or grant any option with respect to, any of the Pledged Collateral, or (ii)
create or permit to exist any lien, security interest, option or other charge or
encumbrance upon or with respect to any of the Pledged Collateral, except for
the security interest under this Agreement. 

    SECTION 8.     BANK APPOINTED ATTORNEY-IN-FACT.  The Pledgor hereby
appoints the Bank the Pledgor's attorney-in-fact, with full authority in the
place and stead of the Pledgor and in the name of the Pledgor or otherwise, from
time to time in the Bank's discretion to take any action and to execute any
instrument which the Bank may deem necessary or advisable to accomplish the
purposes of this Agreement (subject to the rights of the Pledgor under Section
6), including, without limitation, to receive, endorse and  collect all
instruments made payable to the Pledgor representing any dividend or other
distribution in respect of the Pledged Collateral or any part thereof and to
give full discharge for the same. 

    SECTION 9.     BANK MAY PERFORM.  If the Pledgor fails to perform any
agreement contained herein, the Bank may itself perform, or cause performance
of, such agreement, and the expenses of the Bank incurred in connection
therewith shall be payable by the Pledgor under Section 13. 

    SECTION 10.    THE BANK'S DUTIES.  The powers conferred on the Bank
hereunder are solely to protect its interest in the Pledged Collateral and shall
not impose any duty upon it to exercise any such powers.  Except for the safe
custody of any Pledged Collateral in its possession and the accounting for
moneys actually received by it hereunder, the Bank shall have no duty as to any
Pledged Collateral, as to ascertaining or taking action with respect to calls,
conversions, exchanges, maturities, tenders or other matters relative to any
Pledged Collateral, whether or not the Bank has or is deemed to have knowledge
of such matters, or as to the taking of any necessary steps to preserve rights
against ally parties or any other rights pertaining to any Pledged Collateral.
The Bank shall be deemed to have exercised reasonable care in the custody and
preservation of the Pledged Collateral in its possession if the Pledged
Collateral is accorded treatment substantially equal to that which the Bank
accords its own property. 

    SECTION 11.    REMEDIES UPON DEFAULT.  If an Event of Default shall have
occurred and be continuing: 

         (a)  The Bank may exercise in respect of the Pledged Collateral, in
addition to other rights and remedies provided for herein or otherwise available
to it, all the rights and remedies of a secured party in default under the
Uniform Commercial Code in effect in the State of Connecticut at that time (the
"Code") (whether or not the Code applies to the affected Collateral), and may
also, without notice except as specified below, sell the Pledged Collateral or
any part thereof in one or more parcels at public or private sale, at any
exchange, broker's board or at any of the Bank's offices or elsewhere, for cash,
on credit or for future delivery, and upon such other terms as the Bank may deem
commercially reasonable.  The Pledgor agrees that, to the extent notice of sale
shall be required by law, at least ten days' notice to the Pledgor of the time
and place of any public sale or the time after which any private sale is to be
made shall constitute reasonable notification. The Bank shall not be obligated
to make any sale of Pledged Collateral regardless of notice of sale having been
given.  The Bank may adjourn any public or private sale from time to time by
announcement at the time and place fixed therefor, and such sale may, without
further notice, be made at the time and place to which it was so adjourned. 


<PAGE>

         (b)  Any cash held by the Bank as Pledged Collateral and all cash
proceeds received by the Bank in respect of any sale of, collection from, or
other realization upon all or any part of the Pledged Collateral may, in the
discretion of the Bank, be held by the Bank as collateral for, and/or then or at
any time thereafter be applied (after payment of any amounts payable to the Bank
pursuant to Section 13) in whole or in part by the Bank against, all or any part
of the Obligations in such order as the Bank shall elect.  Any surplus of such
cash or cash proceeds held by the Bank and remaining after payment in full of
all the Obligations shall be paid over to the Pledgor or to whomsoever may be
lawfully entitled to receive such surplus. 

         (c)  The Pledgor recognizes that the Bank may not effect an 
immediate public sale of any or all securities held as Pledged Collateral and 
may elect to sell the Pledged Collateral over a period of time and/or resort 
to one or more public or private sales thereof, which may result in prices, 
and be on other terms, less favorable to the Pledgor than if such sale were 
immediately made in a public sale. If, at the time of sale, the Bank 
determines that here may be a question as to whether the Pledged Collateral 
may be sold under Section 4(1) of the Securities Act of 1933, as amended  
(the "Securities Act") without restriction, the Bank, in its sole discretion 
at any such sale, may restrict the prospective bidders or purchasers as to 
their number, nature and investment intention (including, without limitation, 
requiring that the persons making such purchases represent and agree, to the 
satisfaction of the Bank, that they meet such criteria and are purchasing the 
securities for their own account, for investment and not with a view toward 
the distribution or resale of any thereof in violation of the Securities 
Act).  The Bank may also sell such Pledged Collateral from time to time in 
limited quantities over a period of time and in transactions limited to 
"brokers' transactions" if needed to comply with Rule 144 promulgated under 
the Securities Act ("Rule 144").  Any sale may be made in one lot, as an 
entirety or in separate parcels, even if such sale is made at a discount from 
 the then current market price of the securities and regardless of the 
availability of Section 4(1) of the Securities Act (without compliance with 
the restrictions under Rule 144), paragraph (k) of Rule 144 or another 
exemption from the registration provisions of the Securities Act or 
registration under the Securities Act. 

    SECTION 12.    PLEDGOR'S COOPERATION.  If the Bank shall determine to
exercise its right to sell all or any of the Pledged Collateral pursuant to
Section 11, the Pledgor agrees that, upon request of the Bank, the Pledgor will,
at his own expense, do or cause to be done all such acts and things as may be
necessary to make such sale of the Pledged Collateral or any part thereof valid
and binding and in compliance with applicable law. 

    SECTION 13.    EXPENSES.  The Pledgor will upon demand pay to the Bank the
amount of any and all reasonable expenses, including the reasonable fees and
expenses of its counsel and of any experts and agents, which the Bank may incur
in connection with the failure by the Pledgor to perform or observe any of the
provisions hereof. This Section is subject to the non-recourse provisions
contained in the Note. 

    SECTION 14.    AMENDMENTS, ETC.  No amendment or waiver of any provision of
this Agreement, and no consent to any departure by the Pledgor here from, shall
in any event be effective unless the same shall be in writing and signed by the
Bank, and then such waiver or consent shall be effective only in the specific
instance and for the specific purpose or which given. 

    SECTION 15.    ADDRESSES FOR NOTICES.  All notices and other communications
provided for hereunder shall be sent in the manner set forth in the Note and to
the addresses set forth in the Note 

    SECTION 16.    CONTINUING SECURITY INTEREST; ASSIGNMENTS UNDER NOTE.  This
Agreement shall create a continuing security interest in the Pledged Collateral
and shall (i) remain in full force and effect until the payment in full of the
Obligations and all other amounts payable under this Agreement, (ii) be binding
upon the Pledgor, his successors and assigns, and (iii) inure, together with the
rights and remedies of the Bank hereunder, to the 

<PAGE>

benefit of, and be enforceable by, the Bank and its successors, transferees and
assigns.  Without limiting the generality of the foregoing clause (iv), the Bank
may assign or otherwise transfer all or any portion of its rights and
obligations under the Note (including, without limitation, all or any portion of
the Loan owing to it) to any other person or entity, and such other person or
entity shall thereupon become vested with all the benefits in respect thereof
granted to the Bank herein or otherwise.  Upon the later of payment in full of
the Obligations and all other amounts payable under this Agreement, the security
interest granted hereby shall terminate and all rights to the Pledged Collateral
shall revert to the Pledgor. Upon any such termination, the Bank will, at the
Pledgor's expense, return to the Pledgor such of the Pledged Collateral as shall
not have been sold or otherwise applied pursuant to the terms hereof and execute
and deliver to the Pledgor such documents as the Pledgor shall reasonably
request to evidence such termination. 

    SECTION 17.    GOVERNING LAW; TERMS.  This Agreement shall be governed by,
and construed in accordance with, the laws of the State of Connecticut, except
as required by mandatory provisions of law and except to the extent that the
validity or perfection of the security interest hereunder, or remedies
hereunder, in respect of any particular Pledged Collateral are governed by the
laws of a jurisdiction other than the State of Connecticut.  Unless otherwise
defined herein or in the Note, terms defined in Article 9 of the Code are used
herein as therein defined. 

    IN WITNESS WHEREOF, the Pledgor has duly executed and delivered this
Agreement as of the date first above written.
