(e) Capital Stock of Merger Sub.

Each certificate evidencing ownership of shares of Merger Sub Common Stock shall thereafter evidence ownership of such shares of capital stock of the Surviving Corporation.

(f) Adjustments to Per Share Merger Consideration.

-5-

Merger (the “Unvested Cash”) shall be, in place of such Unvested Shares, equally subject to such right assigned to Acquiror and shall be withheld by Acquiror and paid (in respect of the cash portion, without interest) to the holders of such Unvested Shares if and to the extent such assigned right expires unexercised by Acquiror pursuant to the terms of the applicable Contract with Company; provided, however, that (i) the Surviving Corporation and Acquiror shall be entitled to deduct and withhold from such payments the amount of withholding imposed for Taxes (as defined in Section 3.15(a)) as required by any applicable Legal Requirements; (ii) a portion of such newly vested cash so distributed may be treated as imputed interest and will be so treated to the extent required under the Code and the regulations promulgated thereunder; (iii)Acquiror shall make all such required payments of newly vested cash according to its normal payroll schedule following the date within a month upon which such cash became vested. Notwithstanding the foregoing, if any such holder paid for Unvested Shares with promissory notes, Unvested Cash which vests shall first be applied towards repayment of accrued interest and then outstanding principal under such promissory notes before being distributed to such holder. Company shall take all actions that may be reasonably necessary to ensure that, from and after the Effective Time, Acquiror (or its assignee) is entitled to exercise any such right assigned hereunder, such that any Unvested Cash shall be returned to Acquiror without payment to such holder (other than payment of the original purchase price of any Unvested Shares converted into Unvested Cash upon exercise of the applicable right by Acquiror according to the terms of the Contract with Company governing such Unvested Shares as of immediately prior to the Effective Time).

2.2 Surrender of Certificates; Payment of Per Share Merger Consideration.

(a) Exchange Agent. BNY Mellon Shareowner Services, LLC shall act as the exchange agent for the Merger (the “Exchange Agent”) to receive and pay out the Per Share Merger Consideration to which the holders of Company Common Stock (“Company Stockholders”) and Company Optionholders (collectively, the “Company Securityholders”) shall become entitled to pursuant to this Article II.

(b) Acquiror to Provide Per Share Merger Consideration. Promptly after the Effective Time, Acquiror shall deposit with the Exchange Agent, as needed, for exchange in accordance with this Article II, the Per Share Merger Consideration. Any cash deposited with the Exchange Agent shall be invested by the Exchange Agent as directed by Acquiror for the benefit of Acquiror; provided, that no such investment or loss thereon shall affect the amounts payable to holders of Company Securityholders pursuant to this Article II.

(c) Exchange Procedures. As soon as reasonably practicable after the Effective Time (and in any event within ten (10) days), Acquiror shall cause the Exchange Agent to mail to each holder of record (as of immediately prior to the Effective Time) of a certificate or certificates or other instruments, including uncertificated shares as represented on the books of Company, evidencing Company Common Stock and Company Stock Options (excluding Assumed Options) that were outstanding immediately prior to the Effective Time (the “Certificates”), and which were converted into the right to receive cash pursuant to Section 2.1(a) and Section 2.1(b): (i) a letter of transmittal in customary form (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 Exchange Agent and shall contain such other provisions as

-6-

Acquiror and the Exchange Agent may reasonably specify); and (ii) instructions for use in effecting the surrender of the Certificates in exchange for the portion of the Per Share Merger Consideration payable upon surrender of said Certificates. Subject to Section 2.2(h), upon surrender of Certificates to the Exchange Agent for cancellation or to such other agent or agents as may be appointed by Acquiror, together with such letter of transmittal, duly completed and validly executed in accordance with the instructions thereto and such other documents as may reasonably be required by the Exchange Agent (including any required Form W-8 or W-9), the holders of such Certificates shall be entitled to receive in exchange therefor a check in the amount of U.S. dollars that the holders thereof have the right to receive pursuant to Section 2.1(a) and Section 2.1(b) subject to the provisions of Section 2.1(g) (regarding the continuation of vesting and repurchase rights), and the Certificates so surrendered shall forthwith be cancelled. Until so surrendered, outstanding Certificates will be deemed from and after the Effective Time, for all corporate purposes, to evidence only the right to receive upon surrender thereof a check in the amount of U.S. dollars that the holders thereof have the right to receive pursuant to Section 2.1(a) and Section 2.1(b) subject to the provisions of Section 2.1(g) (regarding the continuation of vesting and repurchase rights). No interest will be paid or accrued on any cash payable to holders of Certificates. In the event of a transfer of ownership of shares of Company Common Stock that is not registered in the transfer records of Company, a check in the amount of U.S. dollars that the holder thereof has the right to receive pursuant to Section 2.1(a) and Section 2.1(b) subject to the provisions of Section 2.1(g) (regarding the continuation of vesting and repurchase rights) may be issued to a transferee if the Certificate representing such shares of Company Common Stock is presented to the Exchange Agent, accompanied by all documents required to evidence and effect such transfer (including, if requested by Acquiror or the Exchange Agent, a medallion guarantee) and by evidence that any applicable stock transfer Taxes (as defined in Section 3.15(a)) have been paid or are not payable.

(d) Distributions With Respect to Unexchanged Shares. Subject to any applicable Legal Requirements (as defined in Section 3.3(a)(ii)), following surrender of any such Certificates, the Exchange Agent shall deliver to the record holders thereof, without interest, the portion of the Per Share Merger Consideration to which such person is entitled by virtue thereof.

(e) Required Withholding. Each of the Exchange Agent, Acquiror, and the Surviving Corporation shall be entitled to deduct and withhold from any consideration payable or otherwise deliverable pursuant to this Agreement such amounts as are required to be deducted or withheld therefrom under the Internal Revenue Code of 1986, as amended (the “Code”) or under any provision of state, local or non-U.S. tax law or under any other applicable Legal Requirement. To the extent such amounts are so deducted or withheld, such amounts shall be treated for all purposes under this Agreement as having been paid to the person to whom such amounts would otherwise have been paid.

(f) No Liability. At any time following the one hundred eightieth (180^th) day after the Effective Time, the Surviving Corporation shall be entitled to require the Exchange Agent to deliver to it any cash amounts which had been made available to the Exchange Agent and not disbursed to Company Securityholders (including all interest and other income received by the Exchange Agent in respect of all funds made available to it) and, thereafter, such Company Securityholders who have not previously complied with this Section 2.2 shall be entitled to look only to the Surviving Corporation (subject to abandoned property, escheat and

-7-

other similar laws) as general creditors thereof with respect to any portion of the Per Share Merger Consideration that may be payable upon due surrender of the Certificates held by them.

ADDITIONAL AGREEMENTS

6.1 Proxy Statement. As promptly as practicable after the execution of this Agreement, Company and Acquiror, in consultation with each other, shall prepare and Company shall file with the SEC the Proxy Statement. Company shall not make any filing of, or amendment or supplement to the Proxy Statement without Acquiror’s prior written consent (which shall not be unreasonably withheld). Company and Acquiror shall respond to any comments of the SEC or its staff and shall cause the Proxy Statement to be mailed to the

-48-

Company Stockholders at the earliest practicable time after the resolution of any such comments. Company shall notify Acquiror promptly upon the receipt of any comments from the SEC or its staff or any other government officials and of any request by the SEC or its staff or any other government officials for amendments or supplements to the Proxy Statement and shall supply Acquiror with copies of all correspondence between Company or any of its representatives, on the one hand, and the SEC, or its staff or any other government officials, on the other hand, with respect to the Proxy Statement.

Whenever any event occurs which is required to be set forth in an amendment or supplement to the Proxy Statement, Acquiror or Company, as the case may be, shall promptly inform the other of such occurrence and cooperate in filing with the SEC or its staff or any other government officials, and/or mailing to stockholders of Company, such amendment or supplement.

6.2 Company Meeting.

(a) As soon as reasonably practicable following the date of this Agreement, Company shall take all action necessary in accordance with Delaware Law, the Company Charter Documents, the rules of Nasdaq, and all other applicable Legal Requirements, and to call, duly give notice of, convene and hold the Company Meeting. The purpose of the Company Meeting will be to obtain the affirmative vote of the holders of a majority of the outstanding shares of Company Common Stock in favor of the adoption of this Agreement (the “Required Company Stockholder Approval”) and nothing herein shall be deemed to relieve Company of such obligation. Company shall use all commercially reasonable efforts to solicit from its stockholders proxies in favor of the adoption of this Agreement, and shall take all other commercially reasonable action necessary or advisable to secure the Required Company Stockholder Approval including, with the prior written consent of Acquiror, adjourning the Company Meeting to solicit additional proxies if, at the time of the Company Meeting, Company does not have sufficient votes to obtain the Required Company Stockholder Approval (unless, the Company Board concludes in good faith, following the receipt of advice of its outside legal counsel, that it would be a breach of the Company Board’s fiduciary duties to the Company Stockholders under applicable Legal Requirements to do so). Notwithstanding anything to the contrary contained in this Agreement, Company may adjourn or postpone the Company Meeting to the extent necessary to ensure that any necessary supplement or amendment to the Proxy Statement is provided to its stockholders in advance of a vote on the adoption of this Agreement or if, as of the time for which the Company Meeting is originally scheduled (as set forth in the Proxy Statement), there are insufficient shares of Company Common Stock represented (either in person or by proxy) to constitute a quorum necessary to conduct the business of such Company Meeting. Company shall ensure that the calling, notice, convening and conduct of the Company Meeting, and that all proxies solicited by it in connection with the Company Meeting, are solicited and done in compliance with Delaware Law, the Company Charter Documents, the rules of Nasdaq, and all other applicable Legal Requirements. Without the prior written consent of Acquiror, adoption of this Agreement (including adjournment of the Company Meeting, if necessary, if a quorum is present, to solicit additional proxies if there are not sufficient votes in favor of the Required Company Stockholder Approval), election of directors and ratification of the appointment of Company’s independent auditor are the only matters which Company shall propose to be acted on by its stockholders at the Company Meeting.

-49-

(b) Except to the extent expressly permitted by Section 6.5(d): (i) the Company Board shall unanimously recommend that Company’s stockholders vote in favor of the adoption of this Agreement at the Company Meeting; (ii) the Proxy Statement shall include (A) the fairness opinion referred to in Section 3.21, and (B) a statement to the effect that the Company Board has unanimously recommended that the Company Stockholders vote in favor of the adoption of this Agreement at the Company Meeting; and (iii) neither the Company Board nor any committee thereof shall withdraw, withhold, amend, change, qualify or modify, or publicly-propose, or resolve to withdraw, withhold, amend, change, qualify or modify in any manner adverse to Acquiror, the unanimous recommendation of the Company Board that Company’s stockholders vote in favor of the adoption of this Agreement (any of the foregoing actions in this clause (iii), whether by the Company Board or a committee thereof, or, in the case of a tender or exchange offer made by a third party directly to Company’s stockholders, a failure by the Company Board to recommend that Company’s stockholders reject such tender or exchange offer, a “Change in Recommendation”). For purposes of this Agreement, a Change in Recommendation shall be deemed to have occurred if the recommendation referred to in clause (i) of the immediately preceding sentence shall no longer be unanimous.

6.3 Confidentiality. The parties acknowledge that Company and Acquiror have previously executed a Confidentiality Agreement, dated as of February 22, 2008 (the “Confidentiality Agreement”), which Acquiror and Company mutually agree shall continue in full force and effect after the date of this Agreement.

No review pursuant to this Section 6.4 shall affect or be deemed to modify any representation or warranty contained herein, the covenants or agreements of the parties hereto or the conditions to the obligations of the parties hereto under this Agreement.

6.5 No Solicitation.

(a) No Solicitation by Company. Company shall not, and will cause its subsidiaries, and its and its subsidiaries’ respective officers, directors, affiliates, employees, agents and representatives (including any investment banker, attorney, accountant or other advisor or representative retained by, or otherwise working on behalf of, Company or any of its subsidiaries whether on the date hereof or any time thereafter) (collectively, “Representatives”) not to directly or indirectly: (i) solicit, initiate, seek, knowingly encourage, knowingly facilitate or knowingly induce any Acquisition Proposal (as defined in Section 6.5(f)(i)), any inquiry with respect to any Acquisition Proposal, or the making, submission or announcement of, any

Any breach of the foregoing provisions of this subsection by any of Company’s subsidiaries or Representatives shall be deemed to be a breach by Company.

(b) Notification of Unsolicited Acquisition Proposals.

(i) As promptly as practicable after receipt by Company (but in no event more than 24 hours after receipt by Company thereof), and of its subsidiaries or any of its Representatives of any Acquisition Proposal or any request for nonpublic information or any expression of interest or inquiry relating in any way to any Acquisition Proposal or which would reasonably be expected to lead to an Acquisition Proposal, Company shall provide to Acquiror (A) oral and written notice of the material terms and conditions of such Acquisition Proposal, request, expression of interest or inquiry, (B) the identity of the person or group making any such Acquisition Proposal, request, expression of interest or inquiry, (C) a copy of all written materials (including written material provided by e-mail or other electronic format) provided in connection with such Acquisition Proposal, request, expression of interest or inquiry, and (D) a written summary of all material information provided orally in connection with such Acquisition Proposal.

(ii) Engage in negotiations with such third party with respect to such Acquisition Proposal.

(iv) following such five (5) business day period, the Company Board has concluded in good faith, after receipt of advice of its outside legal counsel and financial advisor, that, in light of such Superior Offer, and notwithstanding any negotiations pursuant to Section 6.5(d)(iii)(D) or any resulting amendments, adjustment or revisions proposed to be made by Acquiror to this Agreement, that the failure to effect a Change in Recommendation would be inconsistent with its fiduciary duties to Company’s stockholders under applicable Legal Requirements; and

(v) Company shall not have breached in any material respect any of the provisions set forth in Section 6.2 or this Section 6.5.

(e) Compliance with Tender Offer Rules. Nothing contained in this Agreement shall prohibit the Company Board from taking and disclosing to its stockholders a position contemplated by Rules 14d-9 and 14e-2(a) promulgated under the Exchange Act; provided that Company has otherwise complied with Section 6.5. Without limiting the foregoing proviso, the Company Board shall not effect a Change in Recommendation unless specifically permitted pursuant to the terms of Section 6.2 and Section 6.5(f)(i).

(f) Certain Definitions. For purposes of this Agreement, the following terms shall have the following meanings:

(i) “Acquisition Proposal,” shall mean, with respect to Company and its subsidiaries, any offer or proposal (whether written, oral or otherwise, and whether binding or not), or any public announcement of an intention to make any such offer or proposal, relating to any transaction or series of related transactions (other than the Merger) involving: (A) any purchase or acquisition by any person or “group” (as defined under Section 13(d) of the Exchange Act and the rules and regulations thereunder) of more than a ten percent (10%) interest in the total outstanding voting securities of Company or any of its subsidiaries, or any tender offer or exchange offer that if consummated would result in any person or group beneficially owning ten percent (10%) or more of the total outstanding voting securities of Company or any of its subsidiaries, or any merger, consolidation, business combination or similar transaction involving Company or any of its subsidiaries, (B) any sale, lease (other than in the ordinary course of business), exchange, transfer, exclusive license or other license outside the ordinary course of business or acquisition or disposition of more than ten percent (10%) of the aggregate fair market value of the consolidated assets of Company and its subsidiaries taken as a whole, (C) any liquidation or dissolution of Company, or (D) any extraordinary dividend, whether of cash or other property.

In connection with and without limiting the foregoing, Company and its board of directors shall, if any state takeover statute or similar statute or regulation is or becomes applicable to the Merger and this Agreement or any of the transactions contemplated hereby, use reasonable best efforts to ensure that the Merger and this Agreement, and the other transactions contemplated hereby may be consummated as promptly as practicable on the terms contemplated by this Agreement and otherwise to minimize the effect of such statute or regulation on the Merger, this Agreement, and the transactions contemplated hereby.

6.8 Notification

(a) Company shall give prompt notice to Acquiror of any representation or warranty made by it contained in this Agreement becoming untrue or inaccurate, or any failure of Company to comply with or satisfy in any respect any covenant, condition or agreement to be complied with or satisfied by it under this Agreement, in each case, such that the conditions set forth in Section 7.3(a), Section 7.3(b), or Section 7.3(c) would not be satisfied; provided, however, that no such notification shall affect the representations, warranties, covenants or agreements of the parties or the conditions to the obligations of the parties under this Agreement. Company shall notify Acquiror of any actions commenced against, relating to or involving or otherwise affecting Company or any of its subsidiaries that relate to the consummation of the Merger.

(b) Acquiror shall give prompt notice to Company of any representation or warranty made by it or Merger Sub contained in this Agreement becoming untrue or inaccurate, or any failure of Acquiror or Merger Sub to comply with or satisfy in any respect any covenant, condition or agreement to be complied with or satisfied by it under this Agreement, in each case, such that the conditions set forth in Section 7.2(a) or Section 7.2(b) would not be satisfied; provided, however, that no such notification shall affect the representations, warranties, covenants or agreements of the parties or the conditions to the obligations of the parties under this Agreement.

6.10 Company 401(k) Plan; Company ESPP; Employee Benefit Matters.

(a) 401(k) Plans. Effective as of the day immediately preceding the Closing Date, Company and its subsidiaries, as applicable, shall each terminate any and all group severance, separation or salary continuation plans, programs or arrangements and any and all plans intended to include a Code Section 401(k) arrangement (unless Acquiror provides written

-55-

notice to Company that such 401(k) plan(s) shall not be terminated) (collectively, the “Terminating Company Plans”). Unless Acquiror provides such written notice to Company, no later than five (5) business days prior to the Closing Date, Company shall provide Acquiror with evidence that such Terminating Company Plan(s) have been terminated (effective as of the day immediately preceding the Closing Date) pursuant to resolutions of the Company Board. The form and substance of such resolutions shall be subject to review and approval of Acquiror. If a Terminating Company Plan includes a Code Section 401(k) arrangement, Company will take all actions required so that the termination of such Terminating Company Plan will result in full vesting of all Company contributions in accordance with the terms of such Terminating Company Plan and applicable laws. Company also shall take such other actions in furtherance of terminating such Terminating Company Plan(s) as Acquiror may reasonably require. In the event that the distribution or rollover of assets from the trust of a 401(k) plan that is terminated is reasonably anticipated to trigger liquidation charges, surrender charges, or other fees to be imposed upon the account of any participant or beneficiary of such terminated plan or upon Company or plan sponsor, then Company shall take all such actions as are necessary to reasonably estimate the amount of such charges and/or fees and provide such estimate in writing to Acquiror prior the Closing Date.

(b) Company ESPP. The Company ESPP shall be treated as provided for in Section 2.1(c).

(c) Employee Benefit Matters. All employees of Company who continue employment with Company following the Closing Date shall continue on their existing benefit plans until such time as, in Acquiror’s sole discretion, an orderly transition can be accomplished to employee benefit plans and programs maintained by Acquiror for its and its affiliates’ employees. Acquiror shall take such reasonable actions, to the extent permitted by Acquiror’s benefits programs, as are necessary to allow eligible employees of Company to participate in the health, welfare and other employee benefits programs of Acquiror or alternative benefits programs that are, in the aggregate, substantially similar to those applicable to employees of Acquiror in similar functions and positions on similar terms. Following the Closing Date, employees of Company who continue employment with the Acquiror (or any subsidiary) (i) shall receive credit for purposes of eligibility and vesting for years of service with Company or any of its subsidiaries prior to the Closing Date in the applicable welfare benefit plans and retirement plan (intended to qualify within the meaning of Section 401(a) of the Code) of Acquiror, and (ii) subject to the approval of any insurance carrier and to the extent consistent with applicable law, Acquiror shall cause any and all pre-existing condition limitations, eligibility waiting periods and evidence of insurability requirements under any group health plans of Acquiror in which such employees and their eligible dependents shall participate to be waived. Notwithstanding anything to the contrary, any such credit and waiver will not result in duplication of benefits.

6.11 Indemnification.

(a) If the Merger is consummated, then until the sixth (6^th) anniversary of the Effective Time, Acquiror shall, and shall cause the Surviving Corporation to, fulfill and honor the obligations of Company to its directors and officers as of immediately prior to the Effective Time (the “Company Indemnified Persons”) pursuant to any (i) indemnification provisions under Company’s Certificate of Incorporation or Bylaws as in effect on the date of this

-56-

Agreement, and (ii) written indemnification agreements between Company and such Company Indemnified Parties existing as of the date of this Agreement (the “Company Indemnification Provisions”), with respect to claims arising out of acts or omissions occurring at or prior to the Effective Time. Any claims for indemnification made under this Section 6.11(a) on or prior to the sixth (6^th) anniversary of the Effective Time shall survive such anniversary until the final resolution thereof.

(b) For a period of six (6) years from and after the Effective Time, Acquiror shall, and shall cause the Surviving Corporation to, maintain in effect, if available, directors’ and officers’ liability insurance covering those persons who are currently covered by Company’s directors’ and officers’ liability insurance policy in an amount and on terms no less advantageous, when taken as a whole, to those applicable to the current directors and officers of Company; provided, however, Acquiror may fulfill its obligations under this Section 6.11(b) by purchasing a policy of directors’ and officers’ insurance or a “tail” policy under Company’s existing directors’ and officers’ insurance policy, in either case which (i) has an effective term of six (6) years from the Effective Time, (ii) covers only those persons who are currently covered by Company’s directors’ and officers’ insurance policy in effect as of the date hereof and only for actions and omissions occurring on or prior to the Effective Time, and (iii) contains terms and conditions (including, without limitation, coverage amounts) that are no less advantageous, when taken as a whole, to those applicable to the current directors and officers of Company, provided, further, that in no event shall Acquiror or the Surviving Corporation be required to expend an annual premium for any such coverage in excess of one hundred fifty percent (150%) of the annual premium currently paid by Company under its directors’ and officer’s liability insurance policy in effect as of the date hereof, and if the cost for any such coverage is in excess of such amount, Acquiror or the Surviving Corporation shall only be required to maintain such coverage as is available for such amount.

(c) This Section 6.11 shall survive the consummation of the Merger, is intended to benefit each Company Indemnified Person, shall be binding on all successors and assigns of the Surviving Corporation and Acquiror, and shall be enforceable by Company Indemnified Persons.

6.12 Disqualified Individuals. Ten (10) business days prior to the Closing Date, Company shall, as and to the extent necessary, deliver to Acquiror a schedule which sets forth each person who Company reasonably believes is, with respect to Company or any Company ERISA Affiliate, a “disqualified individual” within the meaning of Section 280G of the Code and the regulations promulgated thereunder, as of the date such schedule is delivered to Acquiror.

6.13 Form S-8. Acquiror will cause the Acquiror Common Stock issuable upon exercise of the Assumed Options for which a Form S-8 registration statement is available to be registered with the SEC on Form S-8 as soon as reasonably practicable following the Closing Date, will exercise commercially reasonable efforts to maintain the effectiveness of such registration statement for so long as the Assumed Options remain outstanding and will reserve a sufficient number of shares of Acquiror Common Stock for issuance upon exercise thereof.

(ii) Company hereby acknowledges and agrees that the agreements contained in this Section 8.3(b) are an integral part of the transactions contemplated by this Agreement, and that, without these agreements, Acquiror would not enter into this Agreement; accordingly, if Company fails to pay in a timely manner the amounts due pursuant to this Section 8.3(b) and, in order to obtain such payment, Acquiror makes a claim that results in a judgment against Company for the amounts set forth in this Section 8.3(b), Company shall pay to Acquiror its reasonable costs and expenses (including attorneys’ fees and expenses) in connection with such suit, together with interest on the amounts set forth in this Section 8.3(b) at the prime rate of Citibank N.A. in effect on the date such payment was required to be made. Payment of the fees described in this Section 8.3(b) shall not be in lieu of damages incurred in the event of breach of this Agreement.

Exhibit B

VOTING AGREEMENT

This Voting Agreement (“Agreement”) is made and entered into as of June 18, 2008, by and between TIBCO Software Inc., a Delaware corporation (“TIBCO”), and the undersigned stockholder (“Stockholder”) of Insightful Corporation, a Delaware corporation (“Insightful”).

RECITALS

A. TIBCO, Mineral Acquisition Corporation, a Delaware corporation and a wholly-owned subsidiary of TIBCO (“Sub”), and Insightful have entered into an Agreement and Plan of Merger dated as of June 18, 2008 (the “Merger Agreement”), which provides for the merger of Sub with and into Insightful (the “Merger”), with Insightful being the surviving corporation. Pursuant to the Merger, all outstanding capital stock of Insightful shall be converted into the right to receive cash as provided in the Merger Agreement.

B. Stockholder is the holder of record and the beneficial owner (as defined in Rule 13d-3 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) of such number of shares of the outstanding capital stock of Insightful, and such number of shares of capital stock of Insightful issuable upon the exercise of outstanding options and warrants, as is indicated on the signature page of this Agreement.

C. In consideration of the execution of the Merger Agreement by TIBCO, Stockholder (in his or her capacity as such) has agreed to vote the Shares (as defined below) and such other shares of capital stock of Insightful over which Stockholder has voting power, so as to facilitate consummation of the transactions contemplated by the Merger Agreement.

NOW, THEREFORE, intending to be legally bound hereby, the parties hereto hereby agree as follows:

1. Certain Definitions. Capitalized terms used but not defined herein shall have the respective meanings ascribed thereto in the Merger Agreement. For all purposes of and under this Agreement, the following terms shall have the following respective meanings:

1.1 “Expiration Date” shall mean the earliest to occur of (i) such date and time as the Merger Agreement shall have been validly terminated pursuant to its terms, (ii) such date and time as the Merger shall become effective in accordance with the terms and conditions set forth in the Merger Agreement or (iii) the date of the written agreement of the parties hereto to terminate this Agreement.

1.2 “Person” shall mean any individual, any corporation, limited liability company, general or limited partnership, business trust, unincorporated association or other business organization or entity, or any governmental authority.

1.3 “Securities” shall mean: (i) all securities which Stockholder directly or indirectly has the power to vote or direct the voting of and shares of Insightful Common Stock (“Current Shares”) and all options, warrants, other securities and other rights to acquire shares

B-1

of Insightful Common Stock (“Current Derivatives”), if any, Owned by Stockholder as of the date of this Agreement, and (ii) all additional securities which Stockholder directly or indirectly has the power to vote or direct the voting of and shares of Insightful Common Stock (“After-Acquired Shares” and, together with the Current Shares, the “Shares”) and all additional options, warrants, other securities and other rights to acquire shares of Insightful Common Stock (“After-Acquired Derivatives” and, together with the Current Derivatives, the “Derivatives”) of which Stockholder acquires Ownership during the period commencing with the execution and delivery of this Agreement until the Expiration Date. Stockholder shall be deemed to “Own” or to have acquired “Ownership” of a Security if Stockholder: (i) is the record owner of such Security; or (ii) is the “beneficial owner” (within the meaning of Rule 13d-3 under the Exchange Act) of such Security.

1.4 “Transfer”. A Person shall be deemed to have effected a “Transfer” of a Security if such Person directly or indirectly (i) sells, tenders, pledges, encumbers, hypothecates, grants an option with respect to, transfers, assigns or otherwise disposes of such Security or any interest therein, or (ii) enters into an agreement, arrangement, understanding or commitment, whether or not in writing, to effect any of the foregoing, or (iii) reduces such Person’s Ownership of such Security.

2. Transfer of Shares.

2.1 Restriction on Transfer of Securities. Subject to Section 2.2, Stockholder shall not, during the term of this Agreement, directly or indirectly: (i) cause or permit any Transfer of any or all of the Securities or any interest therein; (ii) grant any proxies or powers of attorney with respect to any Securities not Transferred or deposit any Securities not Transferred into a voting trust or enter into a voting agreement with respect to any Securities not Transferred, or (iii) take any action (other than any action of Stockholder in the exercise of Stockholder’s fiduciary duties to Company, to the extent any such duties shall exist) that would make any representation or warranty of Stockholder contained herein untrue or incorrect or have the effect of impairing Stockholder from performing any of Stockholder’s obligations under this Agreement (it being understood that nothing contained in this Agreement shall be deemed to restrict the ability of Stockholder to exercise (but not Transfer) any Derivatives held by Stockholder prior to the Expiration Date). Stockholder further agrees with and covenants to TIBCO that Stockholder shall not request that Insightful register the Transfer of any certificate or uncertificated interest representing any of the Securities, unless such Transfer is made in compliance with this Agreement. Stockholder agrees that, in order to ensure compliance with the restrictions referred to herein, Insightful may issue appropriate “stop transfer” instructions to its transfer agent.

2.2 Permitted Transfers. Section 2.1 shall not prohibit (i) a Transfer of Securities expressly contemplated by the Merger Agreement, (ii) a Transfer of Securities by Stockholder to any member of Stockholder’s immediate family or to a trust established for the benefit of Stockholder and/or for the benefit of one or more members of Stockholder’s immediate family or upon the death of Stockholder, (iii) a Transfer in connection with or for the purpose of personal tax-planning, (iv) a Transfer or other disposition of Shares to a charitable organization qualified under Section 501(c)(3) of the Internal Revenue Code of 1986, as amended or (v) a Transfer of Shares pursuant to a court order or as otherwise required by law,

B-2

provided that a Transfer referred to in clauses (ii), (iii) or (iv) shall be permitted only if, as a precondition to such Transfer, the transferee of such Securities agrees to be bound by the terms and conditions of this Agreement.

3. Agreement to Vote Shares. The Stockholder hereby revokes any and all previous proxies granted by such stockholder with respect to such Shares. Until the Expiration Date, at every meeting of stockholders of Insightful called with respect to any of the following, and at every adjournment or postponement thereof, Stockholder shall vote, to the extent not voted by the Person(s) appointed under the Proxy (as defined in Section 4 hereof), the Shares Owned by Stockholder:

3.1 in favor of (i) the adoption of the Merger Agreement, and (ii) the Proxy and any action required in furtherance thereof;

3.2 against approval of any proposal made in opposition to, or in competition with, consummation of the Merger and the transactions contemplated by the Merger Agreement; and

3.3 against any other action that is intended, or could reasonably be expected to, impede, interfere with, expect to frustrate, delay, postpone, or adversely affect the Merger or any of the other transactions contemplated by the Merger Agreement, including without limitation any Acquisition Proposal (as defined in the Merger Agreement) or any agreement or transaction providing for a transaction contemplated by any Acquisition Proposal; provided, that, TIBCO shall use commercially reasonable efforts to give the Stockholder written notice no fewer than three (3) business days prior to the meeting of stockholders of Insightful at which such matters are to be considered, that it is TIBCO’s viewpoint that a vote in favor of such matter would constitute a breach of this Section 3.3.

In all other matters, the Shares shall be voted by and in a manner determined by Stockholder in Stockholder’s sole discretion. Prior to the Expiration Date, Stockholder shall not enter into any agreement or understanding with any Person to vote or give instructions in any manner inconsistent with the terms of this Section 3.

4. Irrevocable Proxy. Concurrently with the execution of this Agreement, Stockholder agrees to deliver to TIBCO a proxy in the form attached hereto as Exhibit A (the “Proxy”), which shall be irrevocable to the fullest extent permissible by applicable law, with respect to the Shares.

5. Representations, Warranties and Covenants of Stockholder.

5.1 Stockholder hereby represents and warrants to TIBCO that, as of the date hereof and at all times until the Expiration Date, (i) Stockholder is and will be the beneficial owner of the Current Shares and Current Derivatives set forth on the signature page of this Agreement (unless otherwise Transferred in accordance with this Agreement, including, but not limited to pursuant to a Permitted Transfer), with full power to vote or direct the voting of the Shares; (ii) the Securities are and will be, unless otherwise Transferred in accordance with this Agreement, including, but not limited to pursuant to a Permitted Transfer, free and clear of any liens, pledges, security interests, claims, options, rights of first refusal, co-sale rights, charges or

B-3

other encumbrances of any kind or nature (other than pursuant to the terms of restricted stock agreements as in effect on the date hereof and except for applicable restrictions on transfer under applicable securities laws or under this Agreement and except for applicable community property laws); (iii) Stockholder does not Own any Securities of Insightful other than the Current Shares and Current Derivatives set forth on the signature page of this Agreement; (iv) with respect to the Shares, Stockholder has and will have full power and authority to make, enter into and carry out the terms of this Agreement and the Proxy (unless such Shares are otherwise Transferred in accordance with this Agreement) and to perform Stockholder’s obligations hereunder and thereunder; (v) the execution, delivery and performance of this Agreement by Stockholder will not violate any agreement or court order to which the Securities are subject, including, without limitation, any voting agreement or voting trust; and (vi) this Agreement has been duly and validly executed and delivered by Stockholder and constitutes a valid and binding agreement of Stockholder, enforceable against Stockholder in accordance with its terms, subject to: (A) laws of general application relating to bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium and the relief of debtors; and (B) rules of law governing specific performance, injunctive relief and other equitable remedies.

5.2 Stockholder agrees that it will not bring, commence, institute, maintain, prosecute, participate in or voluntarily aid any action, claim, suit or cause of action, in law or in equity, in any court or before any governmental entity, which (i) challenges the validity of or seeks to enjoin the operation of any provision of this Agreement, or (ii) alleges that the execution and delivery of this Agreement by Stockholder, either alone or together with the other Insightful voting agreements and proxies to be delivered in connection with the execution of the Merger Agreement, or the approval of the Merger Agreement by the board of directors of Insightful, breaches any fiduciary duty of the board of directors of Insightful or any member thereof; provided, that Stockholder may defend against, contest or settle any such action, claim, suit or cause of action brought against Stockholder that relates solely to Stockholder’s capacity as a director or officer of Insightful.

6. Additional Documents. Stockholder and TIBCO hereby covenant and agree, from the date hereof to the Expiration Date, to execute and deliver any additional documents reasonably necessary or desirable, in the reasonable opinion of TIBCO upon advice of its counsel, to carry out the purpose and intent of this Agreement.

7. Legending of Shares. If so requested by TIBCO, Stockholder hereby agrees that the Shares shall bear a legend stating that they are subject to this Agreement and to an irrevocable proxy.

8. Termination. This Agreement shall terminate automatically and be of no further force or effect as of the Expiration Date.

9. Fiduciary Duties. Each Stockholder is signing this Agreement solely in such Stockholder’s capacity as an owner of his, her or its respective Shares, and nothing herein shall affect, limit, prohibit, prevent or preclude such Stockholder from taking or not taking any action in his or her capacity as an officer or director of Insightful, to the extent permitted by the Merger Agreement.

B-4

10. Miscellaneous.

10.1 Waiver. No waiver by any party hereto of any condition or any breach of any term or provision set forth in this Agreement shall be effective unless in writing and signed by each party hereto. The waiver of a condition or any breach of any term or provision of this Agreement shall not operate as or be construed to be a waiver of any other previous or subsequent breach of any term or provision of this Agreement.

10.2 Severability. In the event that any provision of this Agreement, or the application thereof, becomes or is declared by a court of competent jurisdiction to be illegal, void or unenforceable, the remainder of this Agreement will continue in full force and effect and the application of such provision to other Persons or circumstances will be interpreted so as reasonably to effect the intent of the parties hereto. The parties further agree to replace such void or unenforceable provision of this Agreement with a valid and enforceable provision that will achieve, to the extent possible, the economic, business and other purposes of such void or unenforceable provision.

10.3 Binding Effect; Assignment. Except as provided or required herein, neither party may assign or delegate, in whole or in part, by operation of law or otherwise, either this Agreement or any of the rights, interests, or obligations hereunder without the prior written approval of the other party, and any such assignment without such prior written consent shall be null and void. Subject to the preceding sentence, this Agreement shall be binding upon and shall inure to the benefit of the parties hereto and their respective successors and permitted assigns.

10.4 Amendments. This Agreement may not be modified, amended, altered or supplemented, except upon the execution and delivery of a written agreement executed by each of the parties hereto. A copy of such written agreement shall be provided to Insightful promptly following execution thereof.

10.5 Other Remedies; Specific Performance. Except as otherwise provided herein, any and all remedies herein expressly conferred upon a party will be deemed cumulative with and not exclusive of any other remedy conferred hereby, or by law or equity upon such party, and the exercise by a party of any one remedy will not preclude the exercise of any other remedy and nothing in this Agreement shall be deemed a waiver by any party of any right to specific performance or injunctive relief. The parties hereto acknowledge that irreparable damage would occur in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached. It is accordingly agreed that the parties shall be entitled to seek an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions hereof, this being in addition to any other remedy to which they are entitled at law or in equity.

10.6 Governing Law. This Agreement shall be governed by and construed in accordance with the laws of the State of Delaware, regardless of the laws that might otherwise govern under applicable principles of conflicts of law thereof. The parties hereto hereby irrevocably submit to the exclusive jurisdiction of the courts of the State of Delaware and the Federal courts of the United States of America located within Newcastle County in the State of Delaware solely in respect of the interpretation and enforcement of the provisions of this

B-5

Agreement and of the documents referred to in this Agreement, and in respect of the transactions contemplated hereby and thereby, and hereby waive, and agree not to assert, as a defense in any action, suit or proceeding for the interpretation or enforcement hereof or thereof, that it is not subject thereto or that such action, suit or proceeding may not be brought or is not maintainable in said courts or that the venue thereof may not be appropriate or that this Agreement or any such document may not be enforced in or by such courts, and the parties hereto irrevocably agree that all claims with respect to such action or proceeding shall be heard and determined in such a Delaware State or Federal court. The parties hereby consent to and grant any such court jurisdiction over the Person of such parties and over the subject matter of such dispute and agree that mailing of process or other papers in connection with any such action or proceeding in the manner provided in Section 10.8 or in such other manner as may be permitted by applicable law, shall be valid and sufficient service thereof.

10.7 Entire Agreement. This Agreement and the Proxy and the other agreements referred to in this Agreement set forth the entire agreement and understanding of TIBCO and Stockholder with respect to the subject matter hereof and thereof, and supersede all prior discussions, agreements and understandings between TIBCO and Stockholder, both oral and written, with respect to the subject matter hereof and thereof.

The Shares beneficially owned by the undersigned stockholder of Insightful as of the date of this Proxy are listed on the final page of this Proxy. Upon the execution of this Proxy by the undersigned, any and all prior proxies given by the undersigned with respect to any Shares are hereby revoked and the undersigned hereby agrees not to grant any subsequent proxies with respect to the Shares until after the Expiration Date (as defined below).

This Proxy is irrevocable (to the fullest extent permitted by law), is coupled with an interest and is granted pursuant to that certain Voting Agreement of even date herewith by and between TIBCO and the undersigned stockholder (the “Voting Agreement”), and is granted in consideration of TIBCO entering into that certain Agreement and Plan of Merger (the “Merger Agreement”), by and among TIBCO, Mineral Acquisition Corporation, a Delaware corporation and a wholly-owned subsidiary of TIBCO (“Sub”) and Insightful, which provides for the merger of Sub with and into Insightful (the “Merger”), with Insightful being the surviving corporation. This Proxy shall terminate, and be of no further force and effect, automatically upon the Expiration Date. As used herein, the term “Expiration Date” shall have the same meaning ascribed to it in the Voting Agreement.

The attorneys and proxies named above, and each of them, are hereby authorized and empowered by the undersigned, at any time prior to the Expiration Date, to act as the undersigned’s attorney and proxy to vote the Shares, and to exercise all voting, consent and similar rights of the undersigned with respect to the Shares (including, without limitation, the power to execute and deliver written consents) at every annual, special, adjourned or postponed meeting of stockholders of Insightful and in every written consent in lieu of such meeting: (i) in favor of (A) the adoption of the Merger Agreement and (B) the Proxy and any action required in furtherance thereof; (ii) against approval of any proposal made in opposition to, or in competition with, consummation of the Merger and the transactions contemplated by the Merger Agreement; and (iii) against any other action that is intended, or could reasonably be expected to, impede, interfere with, expect to frustrate, delay, postpone, or adversely affect the Merger or any of the other transactions contemplated by the Merger Agreement, including without limitation any Acquisition Proposal (as defined in the Merger

B-10

Agreement) or any agreement or transaction providing for a transaction contemplated by any Acquisition Proposal; provided, that, TIBCO shall use commercially reasonable efforts to give the Stockholder written notice no fewer than three (3) business days prior to the meeting of stockholders of Insightful at which such matters are to be considered, that it is TIBCO’s viewpoint that a vote in favor of such matter would constitute a breach of this Proxy.

The attorneys and proxies named above may not exercise this Proxy to vote, consent or act on any other matter except as provided above. The undersigned stockholder may vote the Shares on all other matters.

Any obligation of the undersigned hereunder shall be binding upon the successors and assigns of the undersigned.
