      In connection therewith, the undersigned hereby agrees that, except as

3.    From and after the time the Closing Price (as defined below) of the Common

4.    From and after the time the Closing Price of the Common Shares is less
      than $2.00 per share on any trading day, the Disposition of an additional
      25% of the aggregate number of Cummins Common Shares; and

5.    From and after (a) the one year anniversary of the Effective Date or (b)
      the time the Closing Price of the Common Shares is less than $1.50 per

      Notwithstanding the foregoing, the Disposition of all of the Cummins

defined below) of Tasker or (ii) a change in, or the resignation, removal, death
or disability of, any of the following officers of Tasker, for any reason
whatsoever: Tasker's chief executive officer, president or chief operating
officer.

      For purposes of this lock-up agreement, the following defined terms shall
have the following meanings:

      "Change in Control" shall mean:

      (a) the consummation of a merger or consolidation of Tasker with or into
another entity or any other corporate reorganization involving Tasker, if all or
substantially all of the individuals and entities who were the beneficial owners
of the outstanding Common Shares immediately prior to such merger, consolidation
or other reorganization do not beneficially own, directly or indirectly, more
than 50% of the combined voting power of the continuing or surviving entity's
securities outstanding immediately after such merger, consolidation or other
reorganization in substantially the same proportions as their ownership,
immediately prior to such merger, consolidation or other reorganization, of the
outstanding Common Shares;

      (b) the sale, transfer or other disposition of all or substantially all of
Tasker's assets;

      (c) a change in the composition of the Board of Directors of Tasker (the
"Board") , as a result of which fewer than two-thirds of the incumbent directors
are directors who either (i) had been directors of Tasker on the date 24 months
prior to the date of the event that may constitute a Change in Control (the
"original directors") or (ii) were elected, or nominated for election, to the
Board with the affirmative votes of at least a majority of the aggregate of the
original directors who were still in office at the time of the election or
nomination and the directors whose election or nomination was previously so
approved or (iii) satisfy any combination of (i) and (ii); or

                                       2
<PAGE>

      (d) any transaction as a result of which any person is the "beneficial
owner" (as defined in Rule 13d-3 under the Securities Exchange Act of 1934, as
amended (the "Exchange Act")), directly or indirectly, of securities of Tasker
representing at least 50% of the total voting power represented by Tasker's then
outstanding voting securities. For purposes of this clause (d), the term
"person" shall have the same meaning as when used in Sections 13(d) and 14(d) of
the Exchange Act but shall exclude (i) a trustee or other fiduciary holding
securities under an employee benefit plan of Tasker or of a parent or subsidiary
of Tasker and (ii) a corporation owned directly or indirectly by the
stockholders of Tasker in substantially the same proportions as their ownership
of the Common Shares of Tasker.

      A transaction shall not constitute a Change in Control if its sole purpose
is to change the state of Tasker's incorporation or to create a holding company
that will be owned in substantially the same proportions by the persons who held
Tasker's securities immediately before such transaction.

      "Closing Price" shall mean, on any trading day, the closing price per
share of the Common Shares trading on a "regular way" basis as reported on any
recognized over-the-counter quotation system.

      The provisions of this lock-up agreement shall not apply (i) to any
transfer of Cummins Common Shares by the laws of descent and distribution
following the undersigned's death, (ii) in the event that the Shelf Registration
Statement has not been declared effective by the Commission on or before the
Initial Registration Deadline (as defined in the Purchase Agreement) or (iii) to
any transactions relating to Common Shares acquired by the undersigned in open
market transactions after the Effective Date.

      The undersigned acknowledges that the Cummins Common Shares will contain
(i) the legend described in Section 4.22(a) of the Purchase Agreement until the
Shelf Registration Statement has been declared effective by the Commission and
(ii) the legend described in Section 4.22(b) of the Purchase Agreement until
such Cummins Common Shares are no longer subject to restrictions contained in
this agreement.

                                           Very truly yours,

                                           /s/ Barry Cummins
