                            BREAKAWAY SOLUTIONS, INC.

                           STOCK RESTRICTION AGREEMENT

     This Stock Restriction Agreement (this "Agreement") is made as of May 14,
1999, by and between Breakaway Solutions, Inc., a Delaware corporation (the
"Company"), and John A. Loftus (the "Stockholder").

     WHEREAS, the Company, WPL Laboratories, Inc., a Pennsylvania corporation
("WPL") and Celtic Acquisition Corp., a Pennsylvania corporation ("Merger Sub")
and the Stockholder, among others, have entered into an Agreement and Plan of
Reorganization (the "Merger Agreement") whereby WPL will merge with and into
Merger Sub (the "Merger");

     WHEREAS, the Stockholder will acquire an aggregate of 341,035 shares of the
Company's common stock at a price of $2.78 per share (the "Original Purchase
Price") pursuant to the Merger;

     WHEREAS, the Merger Agreement requires, as a condition to closing the
Merger, that the parties hereto enter into this Agreement;

     WHEREAS, the Stockholder desires to induce the Company to close the Merger
and is willing to subject an aggregate of 131,167 shares, representing the total
number of shares of the Company's common stock to be acquired by the Stockholder
in the Merger less the Stockholder's pro rata proportion (based exclusively on
the Outstanding Share Amount) of 50% of the Aggregate Share Number (as defined
in the Merger Agreement) (the "Shares"), of the Company's common stock to the
repurchase option described herein;

              NOW, THEREFORE, the parties hereto agree as follows:

                                    SECTION 1

                                REPURCHASE OPTION

     1.1 In the event the Stockholder's employment ("Continuous Status") with
the Company is terminated by the Stockholder voluntarily or by the Company for
"CAUSE" (as defined below) before all of the Shares are released from the
Company's repurchase option (see Section 2), the Company shall, upon the date of
such termination, have an irrevocable, exclusive option for a period of sixty
(60) days from such date to repurchase up to that number of shares which
constitute the "Unreleased Shares" (as defined in Section 2) at the Original
Purchase Price per share (the "Repurchase Price"). Such option shall be
exercised by the Company by delivering written notice to the Stockholder and, at
the Company's option, (i) by delivering to the Stockholder a check in the amount
of the aggregate Repurchase Price, or (ii) by the Company canceling an amount of
the Stockholder's indebtedness for borrowed money to the Company, if any, equal
to the aggregate Repurchase Price, or (iii) by a combination of (i) and (ii) so
that the combined payment and cancellation of indebtedness equals such aggregate
Repurchase Price. Upon delivery of such notice and the payment of the aggregate
Repurchase Price in any of the ways described above, the Company shall become
the legal and beneficial owner of the Unreleased Shares being repurchased and
all rights and interests therein or relating thereto, and



<PAGE>



the Company shall have the right to retain and transfer to its own name the
number of Unreleased Shares being repurchased by the Company. For the purpose of
this Section 1, "CAUSE" shall mean: (i) the substantial and continuing failure,
after thirty (30) days' notice thereof, to render services to the Company or any
subsidiary of the Company in accordance with the terms or requirements of the
Stockholder's position and duties; (ii) gross negligence or willful misconduct
in the performance of Stockholder's duties or a breach of fiduciary duty to the
Company or any subsidiary of the Company; (iii) the commission of an act of
embezzlement or fraud; (iv) deliberate disregard of the written rules or
policies of the Company or any subsidiary of the Company which results in direct
or indirect loss, damage or injury to the Company or any subsidiary of the
Company; (v) the intentional unauthorized disclosure of any trade secret or
confidential information of the Company or any subsidiary of the Company; or
(vi) the conviction of a felony.

     1.2 Whenever the Company shall have the right to repurchase the Unreleased
Shares hereunder, the Company may designate and assign one or more employees,
officers, directors or stockholders of the Company or other persons or
organizations to exercise all or a part of the Company's repurchase rights under
this Agreement and purchase all or a part of such Unreleased Shares.

                                   SECTION 2

                    RELEASE OF SHARES FROM REPURCHASE OPTION

     2.1 Twenty-five percent (25%) of the Shares shall be released from the
Company's repurchase option on the first anniversary of the date hereof and the
remaining Shares shall be released from the Company's repurchase option ratably
every month over an aggregate period of thirty-six (36) months, provided in each
case that the Stockholder's Continuous Status with the Company has not
terminated prior to the date of any such release, subject to Section 2.2 below.

     2.2 Upon the occurrence of a Change of Control, all Unreleased Shares (as
defined below) shall be released from the Company's repurchase option in full.
For purpose of this Section 2.2, "Change of Control" shall mean the occurrence
of any of the following events:

     (i)    the approval by shareholders of the Company of a merger or
            consolidation of the Company with any other corporation, other
            than a merger or consolidation which would result in the
            voting securities of the Company outstanding immediately prior
            thereto continuing to represent (either by remaining
            outstanding or by being converted into voting securities of
            the surviving entity) more than fifty percent (50%) of the
            total voting power represented by the voting securities of the
            Company or such surviving entity outstanding immediately after
            such merger or consolidation;

     (ii)   any approval by the shareholders of the Company of a plan or
            proposal for the liquidation or dissolution of the Company or
            an agreement or agreements for the sale, lease, exchange,
            disposition or other transfer (in one transaction or a series
            of transactions) by the Company of all or substantially all of
            the assets of the Company; or


                                       2
<PAGE>



      (iii) any "person" (as such term is used in Sections 13(d) and 14(d)
            of the Securities Exchange Act of 1934, as amended) becoming
            the "beneficial owner" (as defined in Rule l3d-3 under said
            Act), directly or indirectly, of securities of the Company
            representing 50% or more of the total voting power represented
            by the Company's then outstanding voting securities; PROVIDED
            HOWEVER, that this section shall not apply to any person or
            persons who, either individually or jointly, on the date of
            this Agreement beneficially owned securities of the Company
            representing 50% or more of the total voting power represented
            by the Company's then outstanding voting securities.

     2.3 In the event that the Company terminates Stockholder's employment other
than for Cause or materially reduces Stockholder's compensation and benefits,
then all of the Unreleased Shares (as defined below) shall immediately be
released from the Company's repurchase option.

     2.4 Any of the Shares which have not yet been released from the Company's
repurchase option are referred to herein as "UNRELEASED SHARES".

                                   SECTION 3

                             RESTRICTION ON TRANSFER

     3.1 Except for the escrow described in Section 4 or the transfer of the
Shares to the Company or its assignees contemplated by this Agreement, none of
the Shares or any beneficial interest therein shall be transferred, encumbered
or otherwise disposed of in any way until the release of such Shares from the
Company's repurchase option in accordance with the provisions of this Agreement.

     3.2 The Stockholder further agrees that, during the period of duration (up
to, but not exceeding, one hundred eighty (180) days) specified by the Company
and an underwriter of Common Stock or other securities of the Company, following
the date of the final prospectus which forms a part of a registration statement
of the Company filed under the Securities Act of 1933, as amended, relating to
the Company's initial public offering, the Stockholder shall not, to the extent
requested by the Company and such underwriter, directly or indirectly sell,
offer to sell, pledge, contract to sell (including, without limitation, any
short sale), grant any option, right or warrant, to purchase or otherwise
transfer or dispose of (other than to donees who agree to be similarly bound)
(each a "Disposition") any of the Shares at any time during such period except
Common Stock included in such registration; provided that other officers of the
Company are prohibited from engaging in a Disposition to the same extent as
provided herein.

                                   SECTION 4

                                ESCROW OF SHARES

     4.1 To ensure the availability for delivery of the Stockholder's Unreleased
Shares upon repurchase by the Company pursuant to the Company's repurchase
option under Section 1 above, the Stockholder shall, upon execution of this
Agreement, deliver and deposit with the


                                       3
<PAGE>



Company the share certificates representing the Unreleased Shares, together with
the stock assignment duly endorsed in blank, attached hereto as EXHIBIT A. The
Unreleased Shares and stock assignment shall be held by the Company pursuant to
the terms of this Agreement.

     4.2 The Company shall not be liable for any act it may do or omit to do
with respect to holding the Unreleased Shares in escrow and while acting in good
faith and in the exercise of its good faith judgment.

     4.3 If the Company or any assignee exercises its repurchase option
hereunder, the Company, upon receipt of written notice of such option exercise
from the proposed transferee, shall take all steps necessary to accomplish such
transfer.

     4.4 When the repurchase option has been exercised or expires unexercised or
a portion of the Shares has been released from such repurchase option, upon
Stockholder's request the Company shall promptly cause a new certificate to be
issued for such released Shares and shall deliver such certificate to the
Company or the Stockholder, as the case may be.

     4.5 Subject to the terms hereof, the Stockholder shall have all the rights
of a stockholder with respect to such Unreleased Shares while they are held in
escrow, including without limitation, the right to vote the Unreleased Shares
and receive any cash dividends declared thereon. If, from time to time during
the term of the Company's repurchase option, there is (i) any stock dividend,
stock split or other change in the Unreleased Shares, or (ii) any acquisition,
merger or sale of assets of the Company which does not release all of the
Unreleased Shares from the Company's repurchase option, any and all new,
substituted or additional securities to which the Stockholder is entitled by
reason of the Stockholder's ownership of the Unreleased Shares shall be
immediately subject to this Agreement, deposited with the Company and included
thereafter as "Unreleased Shares" for purposes of this Agreement and the
Company's repurchase option.

     4.6 THE STOCKHOLDER ACKNOWLEDGES AND AGREES THAT THE RELEASE OF SHARES FROM
THE REPURCHASE OPTION OF THE COMPANY PURSUANT TO SECTION 2 HEREOF IS EARNED ONLY
BY CONTINUING SERVICE AS AN EMPLOYEE OF THE COMPANY (EXCEPT AS PROVIDED IN
SECTION 2.2). THE STOCKHOLDER FURTHER ACKNOWLEDGES AND AGREES THAT THIS
AGREEMENT, THE TRANSACTIONS CONTEMPLATED HEREUNDER AND THE VESTING SCHEDULE SET
FORTH HEREIN DO NOT CONSTITUTE AN EXPRESS OR IMPLIED PROMISE OF CONTINUED
ENGAGEMENT AS AN EMPLOYEE FOR THE VESTING PERIOD, FOR ANY PERIOD, OR AT ALL, AND
SHALL NOT INTERFERE WITH THE STOCKHOLDER'S RIGHT OR THE COMPANY'S RIGHT TO
TERMINATE THE STOCKHOLDER'S EMPLOYMENT RELATIONSHIP AT ANY TIME, WITH OR WITHOUT
CAUSE.

Stockholder understands that he (and not the Company) shall be responsible for
his own federal, state, local or foreign tax liability and any of his other tax

entered into and wholly to be performed within the State of Delaware by Delaware
residents.

     5.5 COUNTERPARTS. This Agreement may be executed in counterparts, each of
which shall be an original, but all of which together shall constitute one and
the same instrument.

     5.6 HEADINGS. The section headings of this Agreement are for convenience
and shall not by themselves determine the interpretation of this Agreement.
