Subsidiary" shall have the meaning set forth in Regulation S-X under the

4. REPRESENTATIONS WARRANTIES AND CERTAIN AGREEMENTS OF INVESTORS. Each
--------------------------------------------------------------
Investor hereby represents and warrants to, and agrees with, the Company,
severally and not jointly, that:

4.1 Authorization. This Agreement, the Voting Agreement and the
-------------
Registration Rights Agreement constitute such Investor's valid and legally
binding obligations, enforceable in accordance with their respective terms
except as may be limited by (i) applicable bankruptcy, insolvency,
reorganization or other laws of general application relating to or affecting the
enforcement of creditors' rights generally and (ii) the effect of rules of law
governing the availability of equitable remedies. Each Investor represents that
such Investor has full power and authority to enter into this Agreement, the
Registration Rights Agreement and the Voting Agreement.

4.2 Purchase for Own Account. This Agreement is made with each
------------------------
Investor in reliance upon such Investor's representation to the Company, which
by such Investor's execution of this Agreement such Investor hereby confirms,
that the Series B Stock to be purchased by such Investor and the Conversion
Shares issuable upon conversion thereof are being acquired for investment for
such Investor's own account, not as a nominee or agent, and not with a view to
the resale or distribution of any part thereof, and that such Investor has no
present intention of selling, granting any participation in, or otherwise
distributing the same. By executing this Agreement, each Investor further
represents that such Investor does not have any

contract, undertaking, agreement or arrangement with any person to sell,
transfer or grant participations to such person or to any third person, with
respect to any of the Series B Stock and/or the Conversion Shares.

4.3 Disclosure of Information. Such Investor has received or has had
-------------------------
full access to all the information it considers necessary or appropriate to make
an informed investment decision with respect to the Purchased Shares to be
purchased by such Investor under this Agreement. Such Investor further has had
an opportunity to ask questions and receive answers from the Company regarding
the terms and conditions of the offering of the Purchased Shares and to obtain
additional information (to the extent the Company possessed such information or
could acquire it without unreasonable effort or expense) necessary to verify any
information furnished to such Investor or to which such Investor had access.
The foregoing, however, does not in any way limit or modify the representations
and warranties made by the Company in Section 3.

4.4 Investment Experience. Such Investor understands and
---------------------
acknowledges that the purchase of the Purchased Shares involves substantial
risk. Such Investor: (i) has experience as an investor in securities of
companies in the development stage and acknowledges that such Investor is able
to fend for itself, can bear the economic risk of such Investor's investment in
the Purchased Shares and has such knowledge and experience in financial or
business matters that such Investor is capable of evaluating the merits and
risks of this investment in the Purchased Shares and protecting its own
interests in connection with this investment and/or (ii) has a preexisting
personal or business relationship with the Company and certain of its officers,
directors or controlling persons of a nature and duration that enables such
Investor to be aware of the character, business acumen and financial
circumstances of such persons.

4.5 Accredited Investor Status. Unless otherwise expressly indicated
--------------------------
on Exhibit A to this Agreement, such Investor is an "accredited investor" within
the meaning of Regulation D promulgated under the Securities Act.

4.6 Restricted Securities. Each Investor understands that the

---------------------
Purchased Shares and the Conversion Shares are characterized as "restricted
securities" under the Securities Act inasmuch as they are being acquired from
the Company in a transaction not involving a public offering and that under the
Securities Act and applicable regulations thereunder such securities may be
resold without registration under the Securities Act only in certain limited
circumstances. In this connection, such Investor represents that such Investor
is familiar with Rule 144 of the U.S. Securities and Exchange Commission, as
presently in effect, and understands the resale limitations imposed thereby and
by the Securities Act. Such Investor understands that the Company is under no
obligation to register any of the securities sold hereunder (or any securities
issuable upon conversion thereof) except

as provided in the Registration Rights Agreement. Such Investor understands
that no public market now exists for any of the Purchased Shares or the
Conversion Shares and that it is uncertain whether a public market will ever
exist for the Purchased Shares or the Conversion Shares.

4.7 Further Limitations on Disposition. Without in any way limiting
-----------------------------------
the representations set forth above, such Investor further agrees not to make
any disposition of all or any portion of the Purchased Shares or the Conversion
Shares unless and until:

(a) there is then in effect a registration statement under the
Securities Act covering such proposed disposition and such disposition is made
in accordance with such registration statement; or

(b) (i) such Investor shall have notified the Company of the proposed
disposition and shall have furnished the Company with a statement of the
circumstances surrounding the proposed disposition, and (ii) such Investor shall
have furnished the Company, at the expense of such Investor or its transferee,
with an opinion of counsel, reasonably satisfactory to the Company, that such
disposition will not require registration of such securities under the 1933 Act.

Notwithstanding the provisions of paragraphs (a) and (b) above, no such
registration statement or opinion of counsel shall be required: (i) for any
transfer of any Purchased Shares or Conversion Shares in compliance with SEC
Rule 144 or Rule 144A, or (ii) for any transfer of Purchased Shares or
Conversion Shares by an Investor that is a partnership or a corporation to (A) a
partner of such partnership or shareholder of such corporation, (B) a retired
partner of such partnership who retires after the date hereof, (C) the estate of
any such partner or shareholder, or (iii) for the transfer by gift, will or
interstate succession by any Investor to his or her spouse or lineal descendants
or ancestors or any trust for any of the foregoing; provided that in each of the
--------
foregoing cases the transferee agrees in writing to be subject to the terms of
this Section 4 (other than Section 4.5) to the same extent as if the transferee
were an original Investor hereunder.

4.8 Legends. It is understood that the certificates evidencing the
-------
Purchased Shares and the Conversion Shares will bear the legends set forth
below:

(a) THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER
THE SECURITIES ACT OF 1933, AS AMENDED (THE "ACT"), OR UNDER THE SECURITIES LAWS
OF CERTAIN STATES. THESE SECURITIES ARE SUBJECT TO RESTRICTIONS ON
TRANSFERABILITY AND RESALE AND MAY NOT BE TRANSFERRED OR RESOLD EXCEPT AS
PERMITTED UNDER THE ACT AND THE APPLICABLE STATE SECURITIES LAWS, PURSUANT TO
REGISTRATION OR EXEMPTION THEREFROM.

INVESTORS SHOULD BE AWARE THAT THEY MAY BE REQUIRED TO BEAR THE FINANCIAL RISKS
OF THIS INVESTMENT FOR AN INDEFINITE PERIOD OF TIME. THE ISSUER OF THESE
SECURITIES MAY REQUIRE AN OPINION OF COUNSEL IN FORM AND SUBSTANCE REASONABLY
SATISFACTORY TO THE ISSUER TO THE EFFECT THAT ANY PROPOSED TRANSFER OR RESALE IS
IN COMPLIANCE WITH THE ACT AND ANY APPLICABLE STATE SECURITIES LAWS.

(b) Any legend required by the laws of the State of Delaware or any
other state securities laws, including a legend substantially in the form of the
following:

THE SHARES EVIDENCED BY THIS CERTIFICATE: (1) ARE CONVERTIBLE INTO
SHARES OF COMMON STOCK OF THE COMPANY AT THE OPTION OF THE HOLDER AT ANY TIME
PRIOR TO AUTOMATIC CONVERSION THEREOF, AND (2) AUTOMATICALLY CONVERT INTO COMMON
STOCK OF THE COMPANY IN THE EVENT OF A PUBLIC OFFERING MEETING CERTAIN
REQUIREMENTS OR UPON CERTAIN CONSENTS OF THE HOLDERS OF THE COMPANY'S PREFERRED
STOCK; ALL PURSUANT TO AND UPON THE TERMS AND CONDITIONS SPECIFIED IN THE
COMPANY'S CERTIFICATE OF INCORPORATION. A COPY OF SUCH CERTIFICATE OF
INCORPORATION MAY BE OBTAINED, WITHOUT CHARGE, AT THE COMPANY'S PRINCIPAL
OFFICE.

The legend set forth in (a) above shall be removed by the Company from any
certificate evidencing Purchased Shares or Conversion Shares upon delivery to
the Company of an opinion by counsel, reasonably satisfactory to the Company,
that a registration statement under the 1933 Act is at that time in effect with
respect to the legended security or that such security can be freely transferred
in a public sale without such a registration statement being in effect and that
such transfer will not jeopardize the exemption or exemptions from registration
pursuant to which the Company issued the Purchased Shares or Conversion Shares.

PURCHASE AGREEMENT

THIS AMENDMENT NO. 1 dated as of December 5, 1995 to the Series B Preferred
Stock Purchase Agreement, dated November 13, 1995 (the "Purchase Agreement") by
and among Giga Information Group, Inc. (the "Company"), and the purchasers
listed on Exhibit A thereto (the "Purchasers").

WHEREAS, Section 2.2(a) of the Purchase Agreement, as executed on November
13, 1995, provides that:

Conditions of Additional Closing. At any time or times within thirty (30)
--------------------------------
days immediately following the Closing, the Company may, at one or more closings
(each an "ADDITIONAL CLOSING"), without obtaining the signature, consent or
permission of any of the Investors, offer and sell to other investors ("NEW
INVESTORS"), at a price of not less than $3.50 per share, up to that number of
shares of Series B Stock that is equal to 5,142,856 shares of Series B Stock
less the number of shares of Series B Stock actually issued and sold by the
Company prior to such Additional Closing pursuant to this Agreement and upon
conversion of the Convertible Note (as defined in Section 3.4(c)). New
Investors may include persons or entities who are already Investors under this
Agreement.

WHEREAS, the Company has requested an extension of the period in which it
may hold an Additional Closing to enable it to offer and sell shares of its
Series B Preferred Stock ("Series B Stock") to certain persons who are currently
stockholders, directors, or officers of, or advisors to, or who have other
business relationships with, the Company;

WHEREAS, the parties hereto wish to amend the Series B Purchase Agreement
pursuant to Section 8.9 thereof, to provide for such an extension, as
hereinafter provided;

NOW THEREFORE, in consideration of the foregoing, and intending to be
legally bound hereby, the parties hereto agree as follows:

1. The Company and each of the Purchasers signing below hereby agree that
Section 2.2(a) of the Purchase Agreement is hereby amended to read in its
entirety as follows:

Conditions of Additional Closing. At any time or times on or before January
--------------------------------
20, 1996, the Company may, at one or more closings (each an "ADDITIONAL
CLOSING"), without obtaining the signature, consent or permission

A-5

of any of the Investors, offer and sell to other investors ("NEW INVESTORS"), at

a price of not less than $3.50 per share, up to that number of shares of Series
B Stock that is equal to 5,142,856 shares of Series B Stock less the number of
shares of Series B Stock actually issued and sold by the Company prior to such
Additional Closing pursuant to this Agreement and upon conversion of the
Convertible Note (as defined in Section 3.4(c)); provided that each New Investor
shall have been, as of November 13, 1995: (i) an employee of, or advisor to,
the Company, (ii) an individual specified in Exhibit I to Amendment No. 1 to the
---------
Purchase Agreement, or (iii) an affiliate of any of the foregoing. New
Investors may include persons or entities who are already Investors under this
Agreement.

Wherever the Purchase Agreement is itself referred to in the Purchase
Agreement, it shall mean the Purchase Agreement as amended by this Amendment No.
1.

2. The Company and the New Investors purchasing Series B Stock at any
Additional Closing will execute counterpart signature pages to this Agreement,
the Registration Rights Agreement, the Voting Agreement and the Co-Sale
Agreement (each as defined in the Purchase Agreement), and such New Investors
will, upon delivery to the Company of such signature pages, become parties to,
and bound by, this Agreement, the Registration Rights Agreement, the Voting
Agreement and the Co-Sale Agreement, each to the same extent as if they had been
Investors at the Closing. Immediately after any Additional Closing, Exhibit A to
---------
the Purchase Agreement will be amended by the Company to list the New Investors
purchasing shares of Series B Stock hereunder and the number of shares of Series
B Stock purchased by each New Investor under the Purchase Agreement at the
Additional Closing.

3. Upon the completion of an Additional Closing as provided in the
Purchase Agreement as amended hereby, each New Investor will be deemed to be an
"INVESTOR" for all purposes of the Purchase Agreement, the Registration Rights
Agreement and the Co-Sale Agreement, and a "SERIES B PURCHASER" for purposes of
the Voting Agreement.

4. This Agreement may be executed in two or more counterparts, each of
which shall be deemed an original but all of which shall constitute one and the
same instrument.
