                                    RECITALS

     A.     Insightful, Predict AG, a Swiss corporation ("Predict"), and the
                                                          -------
shareholders of Predict, including Shareholder, have entered into a Share
Purchase Agreement (the "Purchase Agreement"), executed concurrently with this
                         ------------------
Agreement, pursuant to which Insightful shall acquire all of the outstanding
capital stock of Predict.

     B.     Shareholder shall provide services to, and shall be employed by,
Predict pursuant to the terms of an employment agreement (the "Employment
                                                               ----------
Agreement"), executed concurrently with this Agreement, by and between Predict
---------
and Shareholder.

     C.     Pursuant to the Purchase Agreement, certificates representing
115'810 shares of common stock of Insightful (the "Insightful Common Stock"),
                                                   -----------------------
$0.01 par value, otherwise issuable to Shareholder shall be held by, and the
shares represented by such certificates shall be subject to forfeiture to,
Insightful, all in accordance with the terms and conditions of this Agreement,
the execution of which is a condition precedent to the consummation of the
transactions contemplated by the Purchase Agreement.

     D.     Capitalized terms used but not otherwise defined in this Agreement
shall have the meaning set forth in the Purchase Agreement.

     NOW, THEREFORE, in consideration of the promises and of the mutual
covenants of the parties contained in this Agreement, the parties hereby agree
as follows:

1.     HOLDBACK OF PLEDGE SHARES.

          (a)     At the Closing Date, certificates representing 93'806 shares
of Insightful Common Stock otherwise issuable to Shareholder pursuant to the
Purchase Agreement (the "Initial Pledge Shares" and, together with the Repledge
                         ---------------------
Shares (as defined in Section 1(d) of this Agreement) and the New Pledge Shares
(as defined in Section 1(e) of this Agreement), the "Pledge Shares") shall be
                                                     -------------
held by, and the shares represented by such


<PAGE>
certificates shall be subject to forfeiture by Shareholder to, Insightful, in
accordance with the provisions of Section 2 of this Agreement.   Upon the
consummation of the transactions contemplated by the Purchase Agreement (in the
case of the Initial Pledge Shares) or at the time of issuance (in the case of
any New Pledge Shares), Shareholder shall be deemed to have pledged such Pledge
Shares to Insightful, and Insightful shall hold such Pledge Shares in accordance
with the terms and conditions of this Agreement.  So long as any Pledge Shares
are held by Insightful under this Agreement, Insightful shall have, and the
Shareholder shall be deemed to have granted to Insightful, a perfected,
first-priority security interest in the Pledge Shares, to secure the obligations
of the Shareholder under the Employment Agreement.

          (b)     Notwithstanding the foregoing, unless and until retransferred
to Insightful in accordance with the provisions of Section 2 of this Agreement,
the Pledge Shares shall be held of record by and owned by Shareholder for all
purposes (including Swiss federal, cantonal and municipal income tax and U.S.
income tax purposes), and Shareholder shall have the full right to vote the
Pledge Shares on all matters coming before the stockholders of Insightful.  For
U.S. federal and state income tax purposes, as well as for Swiss federal,
cantonal and municipal income tax purposes, any dividends paid or other
distributions made with respect to the Pledge Shares shall be income of
Shareholder and shall be immediately disbursed by Insightful to Shareholder.

          (c)     Any attempt by Shareholder to sell, exchange, transfer, pledge
or otherwise dispose of the Pledge Shares before the release of the Pledge
Shares pursuant to Section 3 of this Agreement shall be null and void and shall
have no force or effect.

          (d)     On the first anniversary of the Closing Date, certificates
representing 22'004 Indemnification Shares (the "Repledge Shares") shall
                                                 --------
continue to be held by Purchaser, but shall be deemed to constitute Pledge
Shares hereunder and shall be subject to forfeiture to Purchaser pursuant to the
provisions of this Agreement.

          (e)     In the event of any stock dividend, stock split, consolidation
of shares or any like capital adjustment of the outstanding securities of
Insightful, any new, substituted or additional securities or other property to
which Shareholder becomes entitled by reason of his ownership of the Pledge
Shares (the "New Pledge Shares") shall be subject to forfeiture with the same
             -----------------
force and effect, and in the same proportion, as the Pledge Shares are subject
to forfeiture immediately before the event.

          (f)     Concurrent with the execution of this Agreement, Shareholder
shall execute and deliver to Insightful one or more stock powers endorsed in
blank, in a form reasonably acceptable to the parties.  Thereafter, Shareholder
shall execute and deliver to Insightful such other documentation as Insightful
shall reasonably require to carry out the purposes of this Agreement.

          (g)     Any shares forfeited to Insightful pursuant to Section 2 shall
be retransferred to Insightful for cancellation.

<PAGE>
          (a)     In the event that, during the period beginning on the date of
this Agreement and continuing until the date that is 36 months after the Closing
Date (the "Pledge Period"), Shareholder (a) voluntarily ceases to be employed by
           -------------
Predict for any reason other than his death, his Total Disability (as defined
below) or Good Reason (as defined below) or (b) is terminated by Predict for
Cause (as defined below), Shareholder shall, without any action on the part of
Shareholder, immediately forfeit to Insightful, as liquidated damages, the
Pledge Shares (other than any Pledge Shares that have been previously released
pursuant to Section 3 of this Agreement).

          (b)     For purposes of this Agreement, "Cause" shall mean and is

such notification; or

               (iii)     the conviction of Shareholder of any felony that
impairs the business, goodwill or reputation of Insightful or Predict or that
compromises Shareholder's ability to represent Insightful or Predict with the
public;

               (iv)     any willful misconduct by Shareholder in connection with
his responsibilities as an employee that impairs the business, goodwill or
reputation of Insightful or Predict or that compromises Shareholder's ability to
represent Insightful or Predict with the public; or

               (v)     Shareholder's unreasonable refusal to perform his lawful
material duties as an employee of Predict, to adhere to explicitly stated and
reasonable guidelines of employment or to follow the reasonable directives of
the Board of Directors of Predict, provided that Shareholder has been notified
in writing of such unreasonable refusal and has failed to discontinue such
refusal within a reasonable time period after such notification.

          (c)     For the purposes of this Agreement, "Good Reason" shall mean
                                                       -----------
and is limited to the occurrence of the following events:

               (i)     a material change in Shareholder's status, title,
position or responsibilities that represents a substantial reduction in such
status, title, position or responsibilities as in effect immediately before the
change, except as a result of the termination of Shareholder's employment by
Predict for Cause or because of his death or Total Disability, or by Shareholder
other than for Good Reason or the assignment to Shareholder of any material
duties or responsibilities that are substantially inconsistent with such status,
title, position or responsibilities; or

               (ii)     failure by Predict to timely pay, or reduction by
Predict, of Shareholder's annual base salary, except for reductions that are
generally applicable to all employees of Predict of similar position and
authority;

<PAGE>
               (iii)     a requirement by Predict that the principal place of
business at which Shareholder performs his duties be changed to a location more
than 50 miles from the current location of Predict's office in Basel,
Switzerland;

               (iv)     a failure by Predict to continue in effect any benefits
provided to Shareholder, unless Insightful provides Shareholder with a plan or
plans that provide substantially similar benefits, or the taking of any action
by Predict that would adversely affect Shareholder's benefits under any such
plans or deprive Shareholder of any material fringe benefit enjoyed by him,
except to the extent that such loss or reduction of benefits is applicable to
all employees of Predict of similar position and authority; or

               (v)     any material breach by Predict of any provision of the
Employment Agreement.

          (d)     For purposes of this Agreement, "Total Disability" shall mean
                                                   ----------------
a mental or physical impairment of Shareholder that renders him, or is
reasonably expected to render him, unable to perform the material services
contemplated by the Employment Agreement for a period of three months, whether
or not consecutive, in any 12-month period.   A determination of Total
Disability shall be made by a physician satisfactory to both Shareholder and
Insightful; provided, that if Shareholder and Insightful do not agree on a
physician, Shareholder and Insightful shall each select a physician and these
two physicians shall together select a third physician, whose determination as
to Total Disability shall be binding on all parties.

such Pledge Shares) shall be released by Insightful to Shareholder, and shall no
longer be subject to forfeiture (the "Released Shares"), on each of the second
                                      ---------------

to Shareholder the certificate or certificates representing the applicable
number of Released Shares, plus any dividends paid or other distributions made
with respect to the Released Shares.

          (b)     Notwithstanding the foregoing, all remaining Pledge Shares

                  ---------------
any heir, personal representative, successor or assign of either party, resort

<PAGE>
modified, waived, terminated or discharged, signed by the Chief Executive
Officer or [Chief Financial Officer] of Insightful (or other person duly
authorized by Insightful) and Shareholder.  Each such amendment, modification,
waiver, termination or discharge shall be effective only in the specific

this Agreement shall be varied, contradicted or explained by any oral agreement,
course of dealing or performance or any other matter not set forth in an

          (l)     Rights Cumulative.  The rights and remedies provided by this

                  ---------
Agreement in any instance to exercise any right, power or privilege under this
Agreement or under law shall constitute a waiver of any other right, power or
privilege or of the same right, power or privilege in any other instance.  All
waivers by either party to this Agreement must be contained in a written
instrument signed by the party to be charged and, in the case of Insightful, by
the Chief Executive Officer or [Chief Financial Officer] of Insightful (or other
person duly authorized by Insightful).

          (n)     Arbitration.  Any controversy, claim or dispute arising out of

or relating to this Agreement between the parties, their successors, assignees,
affiliates or agents, shall be settled by arbitration in accordance with the
National Rules for the Resolution of Employment Disputes of the American
Arbitration Association then in effect.   The arbitration shall be conducted in
[Seattle, Washington] by one arbitrator either mutually agreed upon by
Insightful and Shareholder or chosen in accordance with the AAA Rules, except
that the parties shall have any right to discovery as would be permitted by the
Federal Rules of Civil Procedure for a period of 90 days following the
commencement of the arbitration and the arbitrator shall resolve any dispute
which arises in connection with such discovery.  The parties agree to abide by
all decisions and awards rendered in such proceedings, and decisions and awards
rendered by the arbitrator shall be final and conclusive and may be entered in
any court having jurisdiction as a basis of judgment and of the issuance of
execution for its collection.  All such controversies, claims or disputes shall
be resolved by arbitration in lieu of any action at law or equity; provided
however, that nothing in this subsection 4(n) shall be construed as precluding
Insightful from bringing an action for injunctive relief or other equitable
relief.  The prevailing party shall be entitled to costs, expenses and
reasonable attorneys' fees, and judgment upon the award rendered by the
arbitrator may be entered in any court having jurisdiction.  The parties shall
keep confidential the existence of the claim, controversy or disputes from third
parties (other than arbitrator(s)), and the determination of the arbitration,
unless otherwise required by law.
