                              STOCKHOLDER AGREEMENT

         THIS STOCKHOLDER AGREEMENT, dated as of January 26, 2000 (this
"Agreement"), is made by and among Breakaway Solutions, Inc., a Delaware
corporation (the "Buyer"), Benedict Acquisition Corp., a Delaware corporation
and a wholly owned subsidiary of the Buyer ("Transitory Subsidiary"), and the
holders (the "Stockholders") of the shares of Common Stock, $0.01 par value per

defined herein shall have the meaning set forth in the Merger Agreement (as

         WHEREAS, concurrently herewith, the Buyer, Transitory Subsidiary and
the Company are entering into an Agreement and Plan of Merger (as it may be
amended from time to time in the future in accordance with its terms, the
"Merger Agreement") providing for the merger of Transitory Subsidiary with and
into the Company (the "Merger"), with the Company being the entity surviving the
Merger and becoming a wholly owned subsidiary of the Buyer; and

         WHEREAS, in order to induce the Buyer and Transitory Subsidiary to
enter into the Merger Agreement, the Buyer and Transitory Subsidiary have
requested that the Stockholders, and the Stockholders have agreed to, enter into
this Agreement;

         NOW, THEREFORE, the parties hereto agree as follows:

                                   ARTICLE I

Merger Agreement, the Merger and all agreements related to the Merger and any
actions related thereto at any meeting of the stockholders of the Company, and
at any adjournment thereof (or by written consent in lieu of a meeting), at
which such Merger Agreement and other related agreements (or any amended version
thereof), or such other actions, are submitted for the consideration and vote of
the stockholders of the Company. Each Stockholder hereby agrees that it will not
vote (or give a written consent with respect to) any Shares in favor of the

Subsidiary's entering into this Agreement and the Merger Agreement and incurring
certain related fees and expenses. The

Shares during the term of the proxy granted herein in accordance with the terms
of the proxy granted herein.

party personally within the State of Delaware.
