CONSULTING AGREEMENT
                              --------------------

           This Consulting Agreement ("AGREEMENT") is entered into by and
between John Landry ("CONSULTANT") and Giga Information Group, Inc. ("COMPANY")
dated as of August 23, 1999.

           CONSULTANT has been requested by COMPANY to provide consulting
services and advice as requested by COMPANY in accordance with the terms,
covenants and conditions set forth below. In consideration of the following
terms, covenants and conditions, the parties agree as follows:

           1. Term. The term of this AGREEMENT shall be the period commencing on
August 23, 1999 and ending on August 31, 2001, or until completion of the
project/assignment set forth in paragraph 2, whichever date is earlier. Either
party may also terminate this AGREEMENT upon not less than sixty (60) days'
prior written notice to the other.

           2. Services. CONSULTANT agrees to serve as a consultant to COMPANY
during the term of this AGREEMENT, to provide advice, guidance and knowledge
related to strategy and executive management as reasonably required by COMPANY.
CONSULTANT shall allocate an average minimum of 15 hours per month to his
consulting services hereunder. Nothing contained herein shall preclude
CONSULTANT from representing, performing services for or being employed by such
additional clients, persons or companies (other than a competitor of COMPANY) as
CONSULTANT in his sole discretion sees fit, so long as such activities do not
conflict or interfere with CONSULTANT'S performance under this AGREEMENT.

           3. Independent Contractor. CONSULTANT shall be an independent
contractor in the making and performance of this AGREEMENT and is not, and shall
not be construed to be, an employee, agent or servant of COMPANY. COMPANY shall
have no liability whatsoever for withholding, collection or payment of income
taxes or for taxes of any other nature on behalf of CONSULTANT, and CONSULTANT
hereby agrees to indemnify COMPANY for any liability, cost or expense incurred
by COMPANY as a result of COMPANY'S failure to withhold. Under no circumstances
shall CONSULTANT have or claim to have power of decision hereunder in any
activity on behalf of COMPANY, nor shall he have the power or authority
hereunder to obligate, bind or commit COMPANY in any respect. It is specifically
understood that COMPANY shall not, with respect to CONSULTANT'S services,
exercise or have the power to exercise such control over CONSULTANT as would
indicate or establish that a relationship of employer and employee exists
between CONSULTANT and COMPANY. CONSULTANT is free to engage at CONSULTANT'S
expense such other employees or agents of CONSULTANT that CONSULTANT deems
necessary for the satisfactory completion of the project/assignment set forth in
Paragraph 2, provided that any such employees or agents first execute COMPANY'S
standard form of Confidential and Proprietary Information, Trade Secrets and
Non-Solicitation Agreement. The parties further agree that CONSULTANT shall have
the right to control the manner and means by which the contracted
project/assignment is achieved, subject only to the satisfaction of COMPANY as
to the quality, effectiveness and timeliness of the required results.

           4. Expenses. COMPANY agrees to reimburse CONSULTANT for reasonable
travel, living and related expenses incurred by CONSULTANT when requested by
Company to travel hereunder, upon submission of appropriate documentation.
Airplane travel may be First Class.

           5. Stock Option. Subject to ratification of this AGREEMENT by the
Board of Directors of the COMPANY, CONSULTANT shall receive on the date hereof a
five-year, non-qualified stock option for 25,000 shares of COMPANY Common Stock
under COMPANY's 1999 Share Incentive Plan, having an exercise price equal to the
Fair Market Value of the Common Stock at the time of grant, and in accordance
with a customary grant letter to be entered into with CONSULTANT. The option
will provide for vesting as follows: 2,000 shares on September 30, 1999 and
1,000 shares for each full calendar month thereafter through August 30, 2001.
However, the aforementioned vesting will accelerate upon a Change of Control, as
defined in subsections 13 (b)(i) through (v) of the COMPANY's 1999 Share
Incentive Plan (regardless of any contrary action by the Board), or if
CONSULTANT fails to be nominated or re-elected as a Director, in each case
(regarding his continuing as a Director) without his prior consent. Furthermore,
vesting will terminate: (1) if CONSULTANT terminates this Agreement or (2) if
COMPANY terminates this AGREEMENT.

           6. Confidential Information. CONSULTANT understands and acknowledges
that during the term of this AGREEMENT he may have access to and become
acquainted with certain confidential information and trade secrets, which are
private or confidential in that they are not generally known or available to the
public, or give COMPANY, and its subsidiaries and related companies, an
opportunity to obtain an advantage over competitors who do not know or use such
information. CONSULTANT agrees that he shall not disclose any such confidential
information or trade secrets to any person or entity, either directly or
indirectly, or use said confidential information or trade secrets for his
personal benefit or in any other way, except in the performance of CONSULTANT'S
responsibilities set forth in this AGREEMENT. However, this obligation will not
apply to information which is or becomes publicly available without fault on the
part of CONSULTANT, is already in CONSULTANT'S possession prior to the time
CONSULTANT gains access to the data under this AGREEMENT, is independently
developed by CONSULTANT, or is rightfully obtained from third parties. Upon
termination of this AGREEMENT, CONSULTANT shall return to COMPANY all copies of
all data, materials and documents which belong to COMPANY (whether or not such
data, materials or documents were prepared by COMPANY, the CONSULTANT or
others).

           7. Proprietary Rights. (a) CONSULTANT agrees that if any inventions,
discoveries or improvements are conceived, first reduced to practice, made or
developed in anticipation of, in the course of, or as a result of, work
performed under this AGREEMENT, CONSULTANT will assign to COMPANY the
CONSULTANT'S entire right, title and interest in and to such inventions,
discoveries and improvements, and any patents that may be granted in any country
of the world. CONSULTANT further agrees that, without charge to COMPANY or its
designee, CONSULTANT will sign all papers and do all acts which may be
necessary, desirable or convenient to enable COMPANY at its expense to file and
prosecute applications for patents on such inventions, discoveries and
improvements, and to maintain any such patents granted.

           (b) The entire right, title and interest, including copyright, in all
original works of authorship fixed in any tangible medium or expression
originated and developed by CONSULTANT as a part of the work covered by this
AGREEMENT shall be transferred to and vested in COMPANY. The parties expressly
agree to consider as works made for hire those works ordered or commissioned by
COMPANY which qualify as such in accordance with the copyright laws. For all
such original works, CONSULTANT agrees to provide documentation satisfactory to
COMPANY to assure the conveyance of all such right, title and interest,
including copyright, to COMPANY. The cost of conveying such rights shall be at
COMPANY'S expense. In the event the work is deemed not to be a work for hire,
CONSULTANT irrevocably transfers, assigns and conveys the exclusive copyright
ownership to COMPANY, free and clear of any liens, claims, or other encumbrances
to the fullest extent permitted by law.

           (c) CONSULTANT agrees to disclose and furnish promptly to COMPANY any
and all technical information, computer or other apparatus programs,
specifications, drawings, records, documentation, works of authorship or other
creative works, ideas, knowledge or data, written, oral or otherwise expressed,
originated or developed by CONSULTANT, as a result of work performed under or in
anticipation of this AGREEMENT. CONSULTANT further agrees that all such
information shall be the property of COMPANY, shall be used only in providing
services under this AGREEMENT, and may not be used for other purposes, except
upon such terms as a may be agreed upon by COMPANY in writing.

           (d) CONSULTANT warrants the originality of the work prepared for
COMPANY under this AGREEMENT, its disclosure to COMPANY exclusively, and that no
portion of the work prepared for COMPANY under this AGREEMENT is derived from
any work owned by another party. If such information includes materials
previously developed or copyrighted by CONSULTANT and not originated or
developed under this AGREEMENT, CONSULTANT grants and agrees to grant to COMPANY
any unrestricted, royalty-free license to use and copy such materials.

           (e) CONSULTANT warrants that the use of any work product, or any part
thereof, furnished under this AGREEMENT by CONSULTANT to COMPANY, will not
infringe any U.S. patent, copyright, trade secret or other proprietary right and
that he is not currently bound by any other agreement, restriction or obligation
and will not assume such obligation or restriction which would in any way
interfere or would be inconsistent with the services to be provided to COMPANY
under this AGREEMENT.

           8. Governing Law. This AGREEMENT shall in all respects be
interpreted, enforced and governed under the laws of the Commonwealth of
Massachusetts.

           9. Arbitration. (a) All disputes between CONSULTANT (and his
attorneys, successors, and assigns) and COMPANY (and its affiliates,
shareholders, directors, officers, employees, agents, successors, attorneys, and
assigns) relating in any manner to any and all disputes arising out of or
relating to this AGREEMENT or the interpretation or breach thereof ("Arbitrable
Claims") shall be resolved by arbitration. All persons and entities specified in
the preceding sentence (other than COMPANY and CONSULTANT) shall be considered
third-party beneficiaries of the rights and obligations created by this Section

contract (express or implied) and tort claims of all kinds, as well as all
claims based on any federal, state, or local law, statute, or regulation,
excepting only claims under applicable workers' compensation law and
unemployment insurance claims. Arbitration shall be final and binding upon the
parties and shall be the exclusive remedy for all Arbitrable Claims, except that

breach of Sections 6 and 7 of this AGREEMENT. Subject to the foregoing sentence,
THE PARTIES HEREBY WAIVE ANY RIGHTS THEY MAY HAVE TO TRIAL BY JURY IN REGARD TO
ARBITRABLE CLAIMS.

           (b) Arbitration of Arbitrable Claims shall be in accordance with the
Employment Dispute Resolution Rules of the American Arbitration Association
("AAA Employment Rules"), except as provided otherwise in this AGREEMENT. In any
arbitration, the burden of proof shall be allocated as provided by applicable
law. Either party may bring an action in court to compel arbitration under this
AGREEMENT and to enforce an arbitration award. Otherwise, neither party shall
initiate or prosecute any lawsuit or administrative action in any way related to
any Arbitrable Claim. All arbitration hearings under this AGREEMENT shall be
conducted at the COMPANY office or branch where this AGREEMENT was executed or,
in the event the branch is no longer in operation, at the COMPANY office
geographically closest to the place where this AGREEMENT was executed. The
Federal Arbitration Act shall govern the interpretation and enforcement of this
Section. The fees of the arbitrator shall be split between both parties equally.
All proceedings and all documents prepared in connection with any Arbitrable
Claim shall he confidential and, unless otherwise required by law, the subject
matter thereof shall not be disclosed to any person other than the parties to
the proceedings, their counsel, witnesses and experts, the arbitrator, and, if
involved, the court and court staff.
