AGREEMENT AND PLAN OF MERGER dated as of January 20, 2003, among FORRESTER RESEARCH, INC., a Delaware corporation ("Parent"), WHITCOMB ACQUISITION CORP., a Delaware corporation ("Sub") and a wholly owned subsidiary of Parent, and GIGA INFORMATION GROUP, INC., a Delaware corporation (the "Company"). WHEREAS the respective Boards of Directors of Parent, Sub and the Company have approved the acquisition of the Company by Parent on the terms and subject to the conditions set forth in this Agreement; WHEREAS, in furtherance of such acquisition, Parent proposes to cause Sub to make a tender offer (as it may be amended from time to time as permitted under this Agreement, the "Offer") to purchase all the outstanding shares of common stock, par value $0.001 per share, of the Company (the "Company Common Stock"), including the associated Company Rights (as defined in Section 3.03), at a price per share of Company Common Stock (including the associated Company Right) of $4.75, net to the seller in cash, on the terms and subject to the conditions set forth in this Agreement; WHEREAS, concurrently with the execution and delivery of this Agreement, and as a condition and inducement to Parent entering into this Agreement, each of Gideon I. Gartner, W.R. Hambrecht + Co., LLC and W.R. Hambrecht + Co., Inc. (collectively, the "Principal Shareholders") has entered into a tender and voting agreement, dated as of the date hereof (collectively, the "Tender Agreements"), pursuant to which, among other things, each of the Principal Shareholders has agreed to tender its shares of Company Common Stock to Sub in the Offer. WHEREAS the respective Boards of Directors of Parent, Sub and the Company have approved the merger (the "Merger") of Sub into the Company, or (at the election of Parent) the Company into Sub, on the terms and subject to the conditions set forth in this Agreement, whereby each issued share of Company Common Stock not owned directly by Parent or the Company, other than Appraisal Shares (as defined in Section 2.01(d)), shall be converted into the right to receive the highest per share cash consideration paid pursuant to the Offer; and WHEREAS Parent, Sub and the Company desire to make certain representations, warranties, covenants and agreements in connection with the Offer and the Merger and also to prescribe various conditions to the Offer and the Merger. NOW, THEREFORE, the parties hereto agree as follows: ARTICLE I THE OFFER AND THE MERGER SECTION 1.01. The Offer. (a) Commencement and Expiration of the Offer. Subject to the conditions of this Agreement, as promptly as practicable after the date of this Agreement (but in no event later than five business days after the public announcement of this Agreement), Sub shall, and Parent shall cause Sub to, commence the Offer within the meaning of the applicable rules and regulations of the Securities and Exchange Commission (the "SEC"). The obligation of Sub to, and of Parent to cause Sub to, commence the Offer and accept for payment, and pay for, any shares of Company Common Stock tendered pursuant to the Offer are subject to the conditions set forth in Exhibit A. The initial expiration date of the Offer shall be the 20th business day following the commencement of the Offer (determined using Rules 14d-1(g)(3) and 14d-2 promulgated under the Securities Exchange Act of 1934, as amended (the "Exchange Act")). Sub expressly reserves the right to waive any condition to the Offer or modify the terms of the Offer, except that, without the consent of the Company, Sub shall not and Parent shall not permit Sub to (i) reduce the number of shares of Company Common Stock subject to the Offer, (ii) reduce the price per share of Company Common Stock to be paid pursuant to the Offer, (iii) waive or change the Minimum Tender Condition (as defined in Exhibit A), (iv) modify in any manner adverse to the holders of Company Common Stock or add to the conditions set forth in Exhibit A, (v) except as provided in Section 1.01(b), extend the Offer or (vi) change the form of consideration payable in the Offer. 1

(b) Sub's Ability to Extend the Offer. Notwithstanding the provisions of Section 1.01(a), Sub may, without the consent of the Company, (A) if at the scheduled or any extended expiration date of the Offer (whether extended pursuant to this clause (A) or otherwise) any of the conditions to Sub's obligation to purchase shares of Company Common Stock are not satisfied or waived, extend the Offer for such period as Sub determines; provided that such extension shall be in increments of not more than five business days if all of the conditions set forth in Exhibit A other than the Minimum Tender Condition have been satisfied or waived at such scheduled or extended expiration date, (B) extend the Offer for any period required by any rule, regulation, interpretation or position of the SEC or the staff thereof applicable to the Offer and (C) if at the scheduled or any extended expiration date of the Offer all of the conditions set forth in Exhibit A have been satisfied or waived, Sub may extend the Offer pursuant to an amendment to the Offer providing for a "subsequent offering period" not to exceed twenty (20) business days to the extent permitted under, and in compliance with, Rule 14d-11 under the Exchange Act. (c) Company's Ability to Extend the Offer. (i) In the event that the Minimum Tender Condition has not been satisfied or waived at the scheduled expiration date of the Offer, at the request of the Company, Sub shall, and Parent shall cause Sub to, extend the expiration date of the Offer in such increments as Sub may determine until the earliest to occur of (w) the satisfaction or waiver of such condition, (x) Parent reasonably determines, after March 31, 2003, that such condition to the Offer is not capable of being satisfied on or prior to the Outside Date (as defined in Section 8.01(b)(i)), (y) the termination of this Agreement in accordance with its terms and (z) the Outside Date. (ii) In the event that the waiting period under the HSR Act applicable to the purchase of shares of the Company Common Stock pursuant to the Offer shall not have expired or been terminated at the scheduled expiration date of the Offer, at the request of the Company, Sub shall, and Parent shall cause Sub to, extend the expiration date of the Offer in such increments as Sub may determine until the earliest to occur of (a) the expiration or termination of such waiting period, (b) the termination of this Agreement in accordance with its terms and (c) the Outside Date. (iii) In the event that a failure to satisfy the conditions in subsection (f) of Exhibit A attached hereto shall exist and the cure period described therein shall not have expired at the scheduled expiration date of the Offer, at the request of the Company, Sub shall, and Parent shall cause Sub to, extend the expiration date of the Offer in such increments as Sub may determine until the earliest to occur of (w) the cure of such failure, (x) the expiration of such cure period, (y) the termination of this Agreement in accordance with its terms and (z) the Outside Date. (iv) In the event a notice contemplated by Section 8.05(b)(iv) is delivered to Parent within three business days of the initial expiration date of the Offer, then Sub shall extend the Offer for a period of no less than three business days. (d) Payment Acceptance. On the terms and subject to the conditions of the Offer and this Agreement, Parent shall cause Sub to accept for payment and pay for all shares of Company Common Stock validly tendered and not withdrawn pursuant to the Offer that Sub becomes obligated to purchase pursuant to the Offer as soon as practicable after the expiration of the Offer. (e) SEC Filings. On the date of commencement of the Offer, Parent and Sub shall file with the SEC a Tender Offer Statement on Schedule TO with respect to the Offer, which shall contain an offer to purchase and a related letter of transmittal and summary advertisement (such Schedule TO and the documents included therein pursuant to which the Offer will be made, together with any supplements or amendments thereto, the "Offer Documents"). Each of Parent, Sub and the Company shall promptly correct any information provided by it for use in the Offer Documents if and to the extent that such information shall have become false or misleading in any material respect, and each of Parent and Sub shall take all steps necessary to amend or supplement the Offer Documents and to cause the Offer Documents as so amended or supplemented to be filed with the SEC and to be disseminated to the Company's stockholders, in each case as and to the extent required by applicable Federal securities laws. Parent and Sub shall give the Company and 2

its counsel a reasonable opportunity to review and comment on the Offer Documents prior to their being filed with the SEC or disseminated to the stockholders of the Company. Parent and Sub shall provide the Company and its counsel in writing with any comments Parent, Sub or their counsel may receive from the SEC or its staff with respect to the Offer Documents promptly after the receipt of such comments and shall provide the Company and its counsel with a reasonable opportunity to participate in the response of Parent or Sub to such comments. (f) Funding Obligations. Prior to the expiration of the Offer, Parent shall provide or cause to be provided to Sub on a timely basis the funds necessary to purchase any shares of Company Common Stock that Sub becomes obligated to purchase pursuant to the Offer. SECTION 1.02. Company Actions. (a) Subject to Section 5.02(b), the Company hereby approves of and consents to the Offer, the Merger and the other transactions contemplated by this Agreement (collectively, the "Transactions"). (b) On the date the Offer Documents are filed with the SEC, the Company shall file with the SEC a Solicitation/Recommendation Statement on Schedule 14D-9 with respect to the Offer (such Schedule 14D-9, as amended and supplemented from time to time, the "Schedule 14D-9"), describing the recommendations referred to in Section 3.04(b), or any permitted withdrawal or modification in accordance with Section 5.02(b), and shall mail the Schedule 14D-9 to the holders of Company Common Stock. Each of the Company, Parent and Sub shall promptly correct any information provided by it for use in the Schedule 14D-9 if and to the extent that such information shall have become false or misleading in any material respect, and the Company shall take all steps necessary to amend or supplement the Schedule 14D-9 and to cause the Schedule 14D-9 as so amended or supplemented to be filed with the SEC and disseminated to the Company's stockholders, in each case as and to the extent required by applicable Federal securities laws. The Company shall provide Parent and its counsel in writing with any comments the Company or its counsel may receive from the SEC or its staff with respect to the Schedule 14D-9 promptly after the receipt of such comments. (c) In connection with the Offer, the Company shall cause its transfer agent to promptly furnish Sub with mailing labels containing the names and addresses of the record holders of Company Common Stock as of a recent date and of those persons becoming record holders subsequent to such date, together with copies of all lists of stockholders, security position listings and computer files and all other information as Sub may reasonably request in the Company's possession or control regarding the beneficial owners of Company Common Stock, and shall furnish to Sub such information and assistance (including updated lists of stockholders, security position listings and computer files) as Parent may reasonably request in communicating the Offer to the Company's stockholders. Subject to the requirements of applicable Law (as defined in Section 3.05), and except for such steps as are necessary to disseminate the Offer Documents and any other documents necessary to consummate the Transactions, Parent and Sub shall hold in confidence pursuant to the Confidentiality Agreement (as defined in Section 6.02) the information contained in any such labels, listings and files, shall use such information only for the purpose of communicating the Offer and disseminating any other documents necessary to consummate the Offer, the Merger and the other Transactions and, if this Agreement shall be terminated, shall, upon request, deliver to the Company all copies of such information then in their possession. SECTION 1.03. The Merger. On the terms and subject to the satisfaction or waiver of the conditions set forth in this Agreement, and in accordance with the Delaware General Corporation Law (the "DGCL"), Sub shall be merged with and into the Company at the Effective Time (as defined in Section 1.05). At the Effective Time, the separate corporate existence of Sub shall cease and the Company shall continue as the surviving corporation (the "Surviving Corporation"). The Surviving Corporation shall possess all the rights, privileges, immunities, powers and franchises of the Company and Sub, and the Surviving Corporation shall by operation of law become liable for all of the debts, liabilities and duties of the Company and Sub. The name of the Surviving Corporation shall be Giga Information Group, Inc. and the purpose thereof shall be as set forth in Section 2 of the Certificate of Incorporation of the Surviving Corporation. Notwithstanding the foregoing, Parent may elect at any time after the expiration of the Offer and prior to the Merger, instead of 3

merging Sub into the Company as provided above, to merge the Company with and into Sub; provided, however, that the Company shall not be deemed to have breached any of its representations, warranties or covenants set forth in this Agreement solely by reason of such election. In such event, the parties shall execute an appropriate amendment to this Agreement to reflect the foregoing. At the election of Parent, any direct or indirect wholly owned subsidiary of Parent may be substituted for Sub as a constituent corporation in the Merger. In such event, the parties shall execute an appropriate amendment to this Agreement in order to reflect the foregoing. SECTION 1.04. Closing. The closing (the "Closing") of the Merger shall take place at the offices of Ropes & Gray, One International Place, Boston, Massachusetts 02110 at 10:00 a.m. on the second business day following the satisfaction (or, to the extent permitted by Law, waiver by all parties) of the conditions set forth in Article VII hereof, or at such other place, time and date as shall be agreed in writing between Parent and the Company. The date on which the Closing occurs is referred to in this Agreement as the "Closing Date". SECTION 1.05. Effective Time. Prior to the Closing, Parent shall prepare and give the Company and its counsel the opportunity to review, and on the Closing Date or as soon as practicable thereafter Parent shall file with the Secretary of State of the State of Delaware, a certificate of merger or other appropriate documents (in any such case, the "Certificate of Merger") executed in accordance with the relevant provisions of the DGCL and shall make all other filings or recordings required under the DGCL. The Merger shall become effective at such time as the Certificate of Merger is duly filed with such Secretary of State, or at such other time as Parent and the Company shall agree and specify in the Certificate of Merger (the time the Merger becomes effective being the "Effective Time"). SECTION 1.06. Effects. The Merger shall have the effects set forth in Section 259(a) of the DGCL. SECTION 1.07. Certificate of Incorporation and By-laws. (a) The Certificate of Incorporation of Sub as in effect immediately prior to the Effective Time shall be the Certificate of Incorporation of the Surviving Corporation until thereafter changed or amended as provided therein or by applicable Law. (b) The By-laws of Sub as in effect immediately prior to the Effective Time shall be the By-laws of the Surviving Corporation until thereafter changed or amended as provided therein or by applicable Law. SECTION 1.08. Directors. At the Closing, Parent shall designate the directors of the Surviving Corporation and such directors shall hold office until the earlier of their resignation or removal or until their respective successors are duly elected and qualified, as the case may be. SECTION 1.09. Officers. At the Closing, Parent shall designate the officers of the Surviving Corporation and such officers shall hold office until the earlier of their resignation or removal or until their respective successors are duly elected or appointed and qualified, as the case may be. ARTICLE II EFFECT ON THE CAPITAL STOCK OF THE CONSTITUENT CORPORATIONS; EXCHANGE OF CERTIFICATES SECTION 2.01. Effect on Capital Stock. At the Effective Time, by virtue of the Merger and without any action on the part of the holder of any shares of Company Common Stock or any shares of capital stock of Sub: (a) Capital Stock of Sub. Each issued and outstanding share of capital stock of Sub shall be converted into and become a number of fully paid and non-assessable shares of common stock, par value $0.01 per share, of the Surviving Corporation ("Surviving Corporation Common Stock") equal to (i) the number of shares of Company Common Stock outstanding immediately prior to Effective Time (excluding any shares of Company Common Stock that are owned by any subsidiary of the Company or Parent other than Sub) divided by (ii) 1,000; provided, however, that if the aggregate number of shares 4

of Surviving Corporation Common Stock into which the capital stock of Sub is to be converted pursuant to this Section 2.01(a) is not a whole number, such number shall be rounded up to the next higher whole number. (b) Cancellation of Treasury Stock and Parent-Owned Stock. Each share of Company Common Stock that is owned directly by the Company, Parent or Sub shall no longer be outstanding and shall automatically be canceled and retired and shall cease to exist, and no other consideration shall be delivered or deliverable in exchange therefor. Each share of Company Common Stock that is owned by any subsidiary of the Company or Parent (other than Sub) shall automatically be converted into one fully paid and nonassessable share of Surviving Corporation Common Stock. (c) Conversion of Company Common Stock. (i) Subject to Sections 2.01(b) and 2.01(d), each issued share of Company Common Stock shall be converted into the right to receive in cash the highest price per share of Company Common Stock paid pursuant to the Offer. (ii) The cash payable upon the conversion of shares of Company Common Stock pursuant to this Section 2.01(c) is referred to collectively as the "Merger Consideration". As of the Effective Time, all such shares of Company Common Stock shall no longer be outstanding and shall automatically be canceled and retired and shall cease to exist, and each holder of a certificate representing any such shares of Company Common Stock shall cease to have any rights with respect thereto, except the right to receive Merger Consideration upon surrender of such certificate in accordance with Section 2.02, without interest. (d) Appraisal Rights. Notwithstanding anything in this Agreement to the contrary, shares (the "Appraisal Shares") of Company Common Stock that are outstanding immediately prior to the Effective Time and that are held by any person who is entitled to demand and properly demands appraisal of such Appraisal Shares pursuant to, and who complies in all respects with, Section 262 of the DGCL (the "Appraisal Provisions") shall not be converted into Merger Consideration as provided in Section 2.01(c), but rather the holders of Appraisal Shares shall be entitled to payment of the fair value of such Appraisal Shares in accordance with the Appraisal Provisions; provided, however, that if any such holder shall fail to perfect or otherwise shall waive, withdraw or lose the right to appraisal under the Appraisal Provisions, then the right of such holder to be paid the fair value of such holder's Appraisal Shares shall cease and such Appraisal Shares shall be deemed to have been converted as of the Effective Time into, and to have become exchangeable solely for the right to receive, Merger Consideration as provided in Section 2.01(c). The Company shall serve prompt notice to Parent of any demands received by the Company for appraisal of any shares of Company Common Stock, and Parent shall have the right to participate in and direct all negotiations and proceedings with respect to such demands. Prior to the Effective Time, the Company shall not, without the prior written consent of Parent, make any payment with respect to, or settle or offer to settle, any such demands, or agree to do any of the foregoing. SECTION 2.02. Exchange of Certificates. (a) Paying Agent. Prior to the Effective Time, Parent shall select a bank or trust company in the United States to act as paying agent (the "Paying Agent") for the payment of the Merger Consideration upon surrender of certificates representing Company Common Stock. Parent shall take all steps necessary to enable and cause the Surviving Corporation to provide to the Paying Agent on a timely basis, as and when needed after the Effective Time, cash necessary to pay for the shares of Company Common Stock converted into the right to receive cash pursuant to Section 2.01(c) (such cash being hereinafter referred to as the "Exchange Fund"). If for any reason (including losses) the Exchange Fund is inadequate to pay the amounts to which holders of shares of Company Common Stock shall be entitled under this Section 2.02(a), Parent shall take all steps necessary to enable or cause the Surviving Corporation promptly to deposit in trust additional cash with the Paying Agent sufficient to make all payments required under this Agreement, and Parent and the Surviving Corporation shall in any event be liable for payment thereof. The Exchange Fund shall not be used for any purpose except as expressly provided in this Agreement. 5

(b) Exchange Procedures. As soon as reasonably practicable after the Effective Time, but in no event more than five (5) business days thereafter, the Surviving Corporation shall cause the Paying Agent to mail to each holder of record of a certificate or certificates (the "Certificates") that immediately prior to the Effective Time represented outstanding shares of Company Common Stock whose shares were converted into the right to receive Merger Consideration pursuant to Section 2.01, (i) a letter of transmittal (which shall specify that delivery shall be effected, and risk of loss and title to the Certificates shall pass, only upon delivery of the Certificates to the Paying Agent and shall be in such form and have such other provisions as Parent may reasonably specify) and (ii) instructions for use in effecting the surrender of the Certificates in exchange for Merger Consideration. Upon surrender of a Certificate for cancellation to the Paying Agent, together with such letter of transmittal, duly executed, and such other documents as may reasonably be required by the Paying Agent, the holder of such Certificate shall be entitled to receive in exchange therefor the amount of cash into which the shares of Company Common Stock theretofore represented by such Certificate shall have been converted pursuant to Section 2.01, and the Certificate so surrendered shall forthwith be canceled. In the event of a transfer of ownership of Company Common Stock that is not registered in the transfer records of the Company, payment may be made to a person other than the person in whose name the Certificate so surrendered is registered, if such Certificate shall be properly endorsed or otherwise be in proper form for transfer and the person requesting such payment shall pay any transfer or other taxes required by reason of the payment to a person other than the registered holder of such Certificate or establish to the satisfaction of Parent that such tax has been paid or is not applicable. Until surrendered as contemplated by this Section 2.02, each Certificate shall be deemed at any time after the Effective Time to represent only the right to receive upon such surrender the amount of cash, without interest, into which the shares of Company Common Stock theretofore represented by such Certificate have been converted pursuant to Section 2.01. If any holder of shares of Company Common Stock shall be unable to surrender such holder's Certificates because such Certificates have been lost, mutilated or destroyed, such holder may deliver in lieu thereof an affidavit and indemnity bond in form and substance and with surety reasonably satisfactory to the Surviving Corporation. No interest shall be paid or accrue on the cash payable upon surrender of any Certificate. (c) No Further Ownership Rights in Company Common Stock. The Merger Consideration paid in accordance with the terms of this Article II upon conversion of any shares of Company Common Stock shall be deemed to have been paid in full satisfaction of all rights pertaining to such shares of Company Common Stock, and after the Effective Time there shall be no further registration of transfers on the stock transfer books of the Surviving Corporation of shares of Company Common Stock that were outstanding immediately prior to the Effective Time. If, after the Effective Time, any certificates formerly representing shares of Company Common Stock are presented to the Surviving Corporation or the Paying Agent for any reason, they shall be canceled and exchanged as provided in this Article II. (d) Termination of Exchange Fund. Any portion of the Exchange Fund that remains undistributed to the holders of Company Common Stock for six months after the Effective Time shall be delivered to Parent, upon demand, and any holder of Company Common Stock who has not theretofore complied with this Article II shall thereafter look only to Parent for payment of its claim for Merger Consideration. (e) No Liability. None of Parent, Sub, the Company or the Paying Agent shall be liable to any person in respect of any cash from the Exchange Fund delivered to a public official pursuant to any applicable abandoned property, escheat or similar Law. If any Certificate has not been surrendered prior to five years after the Effective Time (or immediately prior to such earlier date on which Merger Consideration in respect of such Certificate would otherwise escheat to or become the property of any Governmental Entity (as defined in Section 3.05)), any such shares, cash, dividends or distributions in respect of such Certificate shall, to the extent permitted by applicable Law, become the property of the Surviving Corporation, free and clear of all claims or interest of any person previously entitled thereto. (f) Investment of Exchange Fund. The Paying Agent shall invest any cash included in the Exchange Fund, as directed by Parent, on a daily basis. Any interest and other income resulting from such investments shall be paid to Parent. 6

(g) Withholding Rights. Parent shall be entitled to deduct and withhold from the consideration otherwise payable to any holder of Company Common Stock pursuant to this Agreement such amounts as may be required to be deducted and withheld with respect to the making of such payment under the Code (as defined in Section 3.11(b)), or under any provision of state, local or foreign tax Law. (h) Charges and Expenses. The Surviving Corporation shall pay all charges and expenses, including those of the Paying Agent, in connection with the exchange of cash for shares of Company Common Stock.

The Company and each Company Subsidiary is duly qualified to do business in each jurisdiction where the nature of its business or their ownership or leasing of its properties make such qualification necessary except where the failure to so qualify has not had and would not reasonably be expected to have a Company Material Adverse Effect. The Company has made available to Parent true and complete copies of the certificate of incorporation of the Company, as amended to the date of this Agreement (as so amended, the "Company Charter"), and the by-laws of the Company, as amended to the date of this Agreement (as so amended, the "Company By-laws"), and the comparable charter and organizational documents of each Company Subsidiary, in each case as amended through the date of this Agreement. SECTION 3.02. Company Subsidiaries; Equity Interests. (a) The letter, dated as of the date of this Agreement, from the Company to Parent and Sub (the "Company Disclosure Letter") lists each Company Subsidiary and its jurisdiction of organization. All the outstanding shares of capital stock of each Company Subsidiary have been validly issued and are fully paid and nonassessable and, except as set forth in the Company Disclosure Letter, are owned by the Company, by another Company Subsidiary or by the Company and another Company Subsidiary, free and clear of all pledges, liens, charges, mortgages, encumbrances and security interests of any kind or nature whatsoever (collectively, "Liens").

Parent will advance such funds to the Company as the Company requires in order to comply with the provisions of this Section 6.04(a) on terms mutually acceptable to Parent and the Company. (b) All amounts payable pursuant to Section 6.04(a) shall be subject to any required withholding of Taxes or proof of eligibility of exemption therefrom and shall be paid without interest by the Company as soon as practicable following the first acceptance for payment of shares of Company Common Stock pursuant to the Offer.

The Company shall give any required notice to participants in the Company ESPP and each participant shall have the right to exercise his or her outstanding option under the Company ESPP in full based on the accumulated payroll deductions credited to his or her account through the New Exercise Date. From and after the New Exercise Date, no new payroll contributions shall be accepted by, or made to, the Company ESPP. The Company agrees that, from the date of this Agreement through the New Exercise Date, the Company ESPP shall be operated only in the ordinary course and in a manner consistent with the previous operation of the Company ESPP.

(b) In addition to the agreement set forth in Section 6.05(a), from and after the Control Date and from and after the Effective Time, Parent shall cause the Company or the Surviving Corporation, as applicable, to honor in accordance with their respective terms (as in effect on the date of this Agreement), all the Company's employment, severance and termination agreements, plans and policies disclosed in the Company Disclosure Letter, including any change in control provisions contained therein. (c) With respect to any "employee benefit plan", as defined in Section 3(3) of ERISA, maintained by Parent or any of its subsidiaries (including any severance plan), for all purposes, including determining eligibility to participate and vesting, service with the Company or any Company Subsidiary shall be treated as service with Parent or any of its subsidiaries; provided, however, that such service need not be recognized to the extent that such recognition would result in any duplication of benefits.

(a) Parent shall, to the fullest extent permitted by Law, cause the Company (from and after the Control Date) and the Surviving Corporation (from and after the Effective Time) to honor all the Company's obligations to indemnify, defend and hold harmless (including any obligations to advance funds for expenses) the current and former directors and officers of the Company and its subsidiaries against all losses, claims, damages or liabilities arising out of acts or omissions by any such directors and officers occurring prior to the Effective Time to the maximum extent that such obligations of the Company exist on the date of this Agreement, whether pursuant to the Company Charter, the Company By-laws, the DGCL, individual indemnity agreements or otherwise, and such obligations shall survive the Merger and shall continue in full force and effect in accordance with the terms of the Company Charter, the Company By-laws, the DGCL and such individual indemnity agreements from the Effective Time until the expiration of the applicable statute of limitations with respect to any claims against such directors or officers arising out of such acts or omissions. In the event a current or former director or officer of the Company or any of its subsidiaries is entitled to indemnification under this Section 6.06(a), such director or officer shall be entitled to reimbursement from the Company (from and after the Control Date) or the Surviving Corporation (from and after the Effective Time) for reasonable attorney fees and expenses incurred by such director or officer in pursuing such indemnification, including payment of such fees and expenses by the Surviving Corporation or the Company, as applicable, in advance of the final disposition of such action upon receipt of an undertaking by such current or former director or officer to repay such payment if it shall be adjudicated that such current or former director or officer was not entitled to such payment. (b) From and after the Control Date and for a period of six years after the Effective Time, Parent shall cause to be maintained in effect the current policies of directors' and officers' liability insurance maintained by the Company (provided that Parent may either (i) substitute therefor policies with reputable and financially sound carriers or (ii) maintain self insurance or similar arrangements through a financially sound insurance affiliate of Parent, in each case of at least the same coverage and amounts containing terms and conditions 23

which are no less advantageous) with respect to claims arising from or related to facts or events which occurred at or before the Effective Time; provided, however, that Parent shall not be obligated to make annual premium payments for such insurance to the extent such premiums exceed 200% of the annual premiums paid as of the date hereof by the Company for such insurance (such 200% amount, the "Maximum Premium"). If such insurance coverage cannot be obtained at all, or can only be obtained at an annual premium in excess of the Maximum Premium, Parent shall maintain the most advantageous policies of directors' and officers' insurance obtainable for an annual premium equal to the Maximum Premium. The Company represents to Parent that the Maximum Premium is $558,480. (c) The Company will maintain, through the Effective Time, the Company's existing directors' and officers' insurance in full force and effect without reduction of coverage. (d) If the Surviving Corporation or any of its successors or assigns (i) consolidates with or merges into any other person and shall not be the continuing or surviving corporation or entity of such consolidation or merger and the continuing or surviving entity does not assume the obligations of the Surviving Corporation set forth in this Section 6.06, or (ii) transfers all or substantially all of its properties and assets to any person, then, and in each such case, proper provision shall be made so that the successors and assigns of the Surviving Corporation assume, as a matter of law or otherwise, the obligations set forth in this Section 6.06. SECTION 6.07. Fees and Expenses. (a) Except as provided below, all fees and expenses incurred in connection with the Merger and the other Transactions shall be paid by the party incurring such fees or expenses, whether or not the Merger is consummated. (b) The Company shall pay to Parent a fee of $2.75 million if: (i) this Agreement is terminated pursuant to Section 8.01(b)(iii) as a result of the failure of the condition set forth in paragraph (d) of Exhibit A; (ii) the Company terminates this Agreement pursuant to Section 8.01(e); (iii) Parent terminates this Agreement pursuant to Section 8.01(d)(i) or 8.01(d)(ii) as a result of a material breach of Section 5.02; (iv) after the date of this Agreement, any person makes a Company Takeover Proposal and (A) the Offer shall have remained open until the later of (1) the scheduled expiration date immediately following the date such Company Takeover Proposal is made and (2) ten days after the date such Company Takeover Proposal is made, (B) the Minimum Tender Condition is not satisfied at such expiration date, (C) this Agreement is terminated pursuant to Section 8.01(b)(i) or 8.01(b)(iii) (other than as a result of the failure of the condition set forth in paragraph (d) of Exhibit A) and (D) within 12 months of such termination the Company enters into a definitive agreement to consummate, or consummates, the transactions contemplated by such Company Takeover Proposal; or (v) subject to Section 6.07(c), (A) this Agreement is terminated pursuant to Section 8.01(c) as a result of a willful breach by the Company, (B) after such termination, a Company Takeover Proposal is made, and (C) within 12 months of such termination the Company enters into a definitive agreement to consummate, or consummates, the transactions contemplated by any Company Takeover Proposal. Any fee due under this Section 6.07(b) shall be paid by wire transfer of same-day funds on the date of termination of this Agreement (except that in the case of clause (iv) or (v) above such payment shall be made on the date of execution of such definitive agreement or, if earlier, consummation of such transactions). (c) If the Company becomes obligated to pay a fee under Section 6.07(b) as a result of a termination pursuant to Section 8.01(c), Parent may elect, within six months of the date of such termination, not to receive the fee and, if such election is made, may pursue any and all rights, claims and causes of action it may have under Law with respect to the breach giving rise to such right of termination. If Parent elects to receive the fee, and the Company pays the fee as required by Section 6.07(b), the payment by the Company of such fee shall be Parent's and Sub's sole remedy with respect to such breach and each of Parent and Sub shall waive, to the fullest extent permitted by Law, any and all rights, claims and causes of action (other than claims of, or causes of action arising from, fraud) it may have against the Company with respect to such breach. 24

SECTION 6.08. Public Announcements. Parent and Sub, on the one hand, and the Company, on the other hand, shall consult with each other before issuing, and provide each other the opportunity to review and comment upon, any press release or other public statements with respect to the Offer, the Merger and the other Transactions and shall not issue any such press release or make any such public statement prior to such consultation, except as may be required by applicable Law (including foreign regulations relating to competition), court process or by obligations pursuant to any listing agreement with any national securities exchange. SECTION 6.09. Transfer Taxes. All stock transfer, real estate transfer, documentary, stamp, recording and other similar Taxes (including interest, penalties and additions to any such Taxes) ("Transfer Taxes") incurred in connection with the Transactions shall be paid by the party upon whom the primary burden for payment is placed by the applicable law. Each party shall cooperate with the other in preparing, executing and filing any Tax Returns with respect to such Transfer Taxes and shall use reasonable efforts to avail itself of any available exemptions from such Transfer Taxes, and shall cooperate in providing any information and documentation that may be necessary to obtain such exemptions. SECTION 6.10. Directors. Promptly upon the first acceptance for payment of, and payment by Sub for, any shares of Company Common Stock pursuant to the Offer, Sub shall be entitled to designate such number of directors on the Company Board as will give Sub, subject to compliance with Section 14(f) of the Exchange Act, representation on the Company Board equal to at least that number of directors, rounded up to the next whole number, which is the product of (a) the total number of directors on the Company Board (giving effect to the directors elected pursuant to this sentence) multiplied by (b) the percentage that (i) such number of shares of Company Common Stock so accepted for payment and paid for by Sub plus the number of shares of Company Common Stock otherwise owned by Sub or any other subsidiary of Parent bears to (ii) the number of such shares outstanding, and the Company shall, at such time, cause Sub's designees to be so elected; provided, however, that in the event that Sub's designees are appointed or elected to the Company Board, until the Effective Time the Company Board shall have at least three directors who are directors on the date of this Agreement and who are not officers of the Company (the "Independent Directors"); and provided further that, in such event, if the number of Independent Directors shall be reduced below three for any reason whatsoever, any remaining Independent Directors (or Independent Director, if there shall be only one remaining) shall be entitled to designate persons to fill such vacancies who shall be deemed to be Independent Directors for purposes of this Agreement or, if no Independent Directors then remain, the other directors shall designate three persons to fill such vacancies who are not officers, stockholders or affiliates of the Company, Parent or Sub, and such persons shall be deemed to be Independent Directors for purposes of this Agreement. Subject to applicable Law, the Company shall take all action requested by Parent necessary to effect any such election, including mailing to its stockholders the Information Statement containing the information required by Section 14(f) of the Exchange Act and Rule 14f-1 promulgated thereunder, and the Company shall make such mailing with the mailing of the Schedule 14D-9 (provided that Sub shall have provided to the Company on a timely basis all information required to be included in the Information Statement with respect to Sub's designees). In connection with the foregoing, the Company shall promptly, at the option of Sub, either increase the size of the Company Board or obtain the resignation of such number of its current directors as is necessary to enable Sub's designees to be elected or appointed to the Company Board as provided above. SECTION 6.11. Rights Agreement; Consequences if Rights Triggered. The Company Board shall take all action requested in writing by Parent in order to render the Company Rights inapplicable to the Offer, the Merger and the other Transactions. Except as approved in writing by Parent, the Company Board shall not (i) amend the Company Rights Agreement, (ii) redeem the Company Rights or (iii) take any action with respect to, or make any determination under, the Company Rights Agreement, in each case in a manner adverse to Parent or Sub. If any Distribution Date or Stock Acquisition Date occurs under the Company Rights Agreement at any time during the period from the date of this Agreement to the Effective Time, the Company and Parent shall make such adjustment to the Offer Price as the Company and Parent shall mutually agree so as to preserve the economic benefits that the Company and Parent each reasonably expected 25

on the date of this Agreement to receive as a result of the consummation of the Offer, the Merger and the other Transactions. SECTION 6.12. Stockholder Litigation. The Company shall give Parent the opportunity to participate in the defense or settlement of any stockholder litigation against the Company and its directors relating to any Transaction; provided, however, that the Company shall not enter into any such settlement without Parent's consent, which consent shall not be unreasonably withheld.

No statute, rule, regulation, executive order, decree, temporary restraining order, preliminary or permanent injunction or other order enacted, entered, promulgated, enforced or issued by any Governmental Entity or other legal restraint or prohibition preventing the consummation of the Merger or the other Transactions shall be in effect; provided, however, that prior to asserting this condition each of the parties shall have used all reasonable efforts to prevent the entry of any such injunction or other order and to appeal as promptly as possible any such injunction or other order that may be entered. (d) Acceptance of Shares Pursuant to the Offer. Sub shall have accepted shares of Company Common Stock for payment pursuant to the Offer; provided, that the obligation of a party to effect the Merger shall not be conditioned on the fulfillment of the condition set forth in this clause (d) if the failure of Sub to accept shares of Company Common Stock for payment pursuant to the Offer shall have constituted or resulted from a material breach of the Offer or this Agreement by such party. ARTICLE VIII TERMINATION, AMENDMENT AND WAIVER SECTION 8.01. Termination. This Agreement may be terminated at any time prior to the Effective Time, whether before or after receipt of Company Stockholder Approval: (a) by mutual written consent of Parent, Sub and the Company; (b) by either Parent or the Company: (i) if the Offer is not consummated on or before April 30, 2003 (the "Outside Date"), unless the failure to consummate the Offer is the result of a willful and material breach of this Agreement by the party seeking to terminate this Agreement; (ii) if any Governmental Entity issues an order, decree or ruling or takes any other action permanently enjoining, restraining or otherwise prohibiting the acceptance for payment of, or payment for, shares of Company Common Stock pursuant to the Offer or the Merger and such order, decree, ruling or other action shall have become final and nonappealable; or (iii) if as the result of the failure of any of the conditions set forth in Exhibit A to this Agreement, the Offer shall have terminated or expired in accordance with its terms without Sub having accepted 26

shares of Company Common Stock for payment pursuant to the Offer; provided, however, that the right to terminate this Agreement pursuant to this clause (iii) shall not be available to any party whose failure to fulfill any of its obligations under this Agreement results in the failure of any such condition or if the failure of such condition results from facts or circumstances that constitute a willful breach of any representation or warranty under this Agreement by such party; or (iv) if Sub fails to commence the Offer as provided in Section 1.01(a) on or before March 1, 2003 due to the failure of the condition set forth in paragraph (a) of Exhibit A; provided, however, that the right to terminate this Agreement pursuant to this clause (iv) shall not be available to the Company if its failure to fulfill any of its obligations under this Agreement results in the failure of the condition described in paragraph (a) of Exhibit A or if the failure of the condition described in paragraph (a) of Exhibit A results from facts or circumstances that constitute a willful breach of any representation or warranty under this Agreement by the Company; or (c) by Parent, if the Company breaches or fails to perform in any material respect any of its representations, warranties or covenants contained in this Agreement (other than a breach or failure to perform for which Parent has the right to terminate this Agreement pursuant to Section 8.01(d)(ii)), which breach or failure to perform (i) would give rise to the failure of a condition set forth in Exhibit A, and (ii) cannot be or has not been cured within 30 days after the giving of written notice to the Company of such breach (provided that Parent is not then in material breach of any representation, warranty or covenant contained in this Agreement); or (d) by Parent prior to the first acceptance of shares of Company Common Stock for payment pursuant to the Offer: (i) if the Company Board or any committee thereof withdraws or modifies in a manner adverse to Parent or Sub, or publicly proposes to withdraw or modify in a manner adverse to Parent or Sub, its approval or recommendation of this Agreement, the Offer or the Merger, fails to recommend to the Company's stockholders that they accept the Offer and give the Company Stockholder Approval or publicly approves or recommends, or publicly proposes to approve or recommend, any Company Takeover Proposal; or (ii) if the Company or any of its officers, directors, representatives or agents willfully takes any of the actions that would be proscribed by Section 5.02 but for the exceptions therein allowing certain actions to be taken pursuant to the proviso in the first sentence of Section 5.02(a); or (e) by the Company prior to the first acceptance of shares of Company Common Stock for payment pursuant to the Offer in accordance with Section 8.05(b); provided, however, that the Company shall have complied with all provisions thereof, including the notice provisions therein; or (f) by the Company prior to the first acceptance of shares of Company Common Stock for payment pursuant to the Offer, if Parent breaches or fails to perform in any material respect any of its representations, warranties or covenants contained in this Agreement, which breach or failure to perform cannot be or has not been cured within 30 days after the giving of written notice to Parent of such breach (provided that the Company is not then in material breach of any representation, warranty or covenant contained in this Agreement). SECTION 8.02. Effect of Termination. In the event of termination of this Agreement by either the Company or Parent as provided in Section 8.01, this Agreement shall forthwith become void and have no effect.

SECTION 8.03. Amendment. This Agreement may be amended by the parties at any time before or after receipt of the Company Stockholder Approval; provided, however, that after receipt of the Company Stockholder Approval, there shall be made no amendment that by Law requires further approval by the stockholders of the Company without the further approval of such stockholders; and provided, further, that after Sub's purchase of shares in the Offer, no such amendment or modification shall be made that reduces the amount or changes the form of Merger Consideration or otherwise materially and adversely affects the rights of the Company's stockholders hereunder, without the further approval of such stockholders. This Agreement may not be amended except by an instrument in writing signed on behalf of each of the parties hereto. SECTION 8.04. Extension; Waiver. At any time prior to the Effective Time, the parties may (a) extend the time for the performance of any of the obligations or other acts of the other parties, (b) waive any inaccuracies in the representations and warranties contained in this Agreement or in any document delivered pursuant to this Agreement or (c) subject to the proviso of Section 8.03, waive compliance with any of the agreements or conditions contained in this Agreement. Any agreement on the part of a party to any such extension or waiver shall be valid only if set forth in an instrument in writing signed on behalf of such party. The failure of any party to this Agreement to assert any of its rights under this Agreement or otherwise shall not constitute a waiver of such rights. SECTION 8.05. Procedure for Termination, Amendment, Extension or Waiver. (a) A termination of this Agreement pursuant to Section 8.01, an amendment of this Agreement pursuant to Section 8.03 or an extension or waiver pursuant to Section 8.04 shall, in order to be effective, require in the case of Parent, Sub or the Company, action by its Board of Directors or the duly authorized designee of its Board of Directors; provided, that in the case of the Company and in the event the Offer has been consummated and the shares of Company Common Stock have been purchased pursuant thereto, such action shall also require action by a majority of the Independent Directors.

EXHIBIT A CONDITIONS OF THE OFFER Notwithstanding any other term of the Offer or this Agreement, Sub shall not be required to accept for payment or, subject to any applicable rules and regulations of the SEC, including Rule 14e-l(c) under the Exchange Act (relating to Sub's obligation to pay for or return tendered shares of Company Common Stock promptly after the termination or withdrawal of the Offer), to pay for any shares of Company Common Stock tendered pursuant to the Offer unless (i) there shall have been validly tendered and not withdrawn prior to the expiration of the Offer that number of shares of Company Common Stock which, together with that number of shares of Company Common Stock owned by Parent, Sub and Parent's other subsidiaries, would represent more than fifty percent (50%) of the Fully Diluted Shares (the "Minimum Tender Condition") and (ii) any waiting period under the HSR Act applicable to the purchase of shares of Company Common Stock pursuant to the Offer shall have expired or been terminated. The term "Fully Diluted Shares" means all outstanding securities entitled generally to vote in the election of directors of the Company on a fully diluted basis, after giving effect to the exercise or conversion of all options, rights and securities exercisable or convertible into such voting securities.

EXHIBIT 99.1 FOR IMMEDIATE RELEASE FORRESTER RESEARCH TO ACQUIRE GIGA INFORMATION GROUP CAMBRIDGE, Mass., January 21, 2003 . . . Forrester Research, Inc. (Nasdaq: FORR), a leading provider of research and analysis on emerging technologies, and Giga Information Group, Inc. (OTCBB: GIGX), a leading global technology advisory firm, today announced that they have entered into a definitive agreement under which Forrester will acquire Giga. Pursuant to the agreement, Forrester will begin a tender offer for all outstanding shares of Giga for $4.75 per share in cash. The acquisition has been approved unanimously by the boards of directors of each company and is subject to customary conditions, including regulatory and other standard approvals. Gideon Gartner, Giga's founder and owner of 17 percent of its outstanding stock, has agreed to tender his shares in the offer, and W.R. Hambrecht & Co., owner of 15 percent of Giga's stock, has agreed to tender its shares in the offer subject to the approval of its lenders. "We believe that this acquisition significantly expands our coverage and reach," stated George F. Colony, Forrester's chairman of the board and chief executive officer. "Giga brings deep IT research that augments our emerging technology focus, as well as approximately 900 new client relationships. These strengths, together with Giga's reputation for quality, innovative products, and customer service, make Giga an ideal fit for Forrester and our clients." "We have long respected Forrester for the quality of its people, its work, and its approach," stated John F. Andrews, Giga's president and chief executive officer. "It is a tribute to everyone at Giga that Forrester has decided to purchase our company. I believe these two companies will combine into a research powerhouse that will provide unparalleled levels of customer satisfaction." The tender offer requires that at least a majority of Giga's fully diluted shares be tendered. If tenders for 90 percent of Giga's outstanding shares are received, the acquisition is expected to close at the end of February 2003. If a majority but less than 90 percent of Giga's outstanding shares are tendered, Giga would become a majority-owned subsidiary of Forrester and a meeting of Giga's stockholders would need to be called to complete the transaction. In that case, the acquisition would likely be completed during the second quarter of 2003. Following the completion of the transaction, Giga will become a wholly owned subsidiary of Forrester. In conjunction with this news release, Forrester management will host a conference call for investors at 10 a.m. Eastern time today, January 21, 2003. The call will be broadcast live over the Internet.
