and subject to the conditions of this Agreement, the Agreement of Merger and the
Certificate of Merger, Merger Sub will be merged with and into Panopticon (such
remaining entity, as appropriate, the "SURVIVING CORPORATION") in a statutory
merger pursuant to the Agreement of Merger and the Certificate of Merger and in
accordance with applicable provisions of California and Delaware laws as
follows:

                           (a) Conversion of Panopticon Securities.

                                    (i) Total Merger Consideration. In
         connection with the Merger and pursuant to the provisions of this
         Agreement, Broadbase will issue an aggregate of 3,179,810 fully paid
         and nonassessable shares of Broadbase common stock (collectively the
         "TOTAL MERGER CONSIDERATION," and each share individually, an "EXCHANGE
         SHARE") determined as set forth in this Article 2 (provided that
         additional shares of Broadbase common stock may be issued, but only
         with the express written consent of Broadbase (for example, with
         respect to new option grants pursuant to Section 6.4)) in exchange for

         stock, options, warrants and other rights) of Panopticon outstanding
         immediately prior to the Effective Time.

                                    (ii) Conversion of Panopticon Shares.

                                            (A) On the terms and subject to the
              conditions of this Agreement, at the Effective Time, each share of
              Panopticon common stock and preferred stock held by a Panopticon
              Shareholder that is issued and outstanding immediately prior to
              the Effective Time, excluding any Dissenting Shares (as defined in
              Section 8.3(a)) will, by virtue of the Merger and without further
              action on the part of any holder thereof (except as expressly
              provided herein), be converted into and represent the right to
              receive the number of shares of Broadbase common stock that is
              equal to the Conversion Ratio. For purposes of calculating the
              Conversion Ratio, and as used elsewhere in this Agreement, the
              following definitions apply:

                                                     (1) "PANOPTICON SHARE
                  NUMBER" equals the sum of: (x) the total number of shares of
                  Panopticon common stock (not including treasury shares)
                  outstanding, and which Panopticon has promised to issue or to
                  recommend to the Panopticon board of directors to issue, as of
                  the date of this Agreement, and (y) the total number of shares
                  of Panopticon common stock issuable upon exercise of all
                  Panopticon Options (as defined in Section 4.5), Panopticon
                  Warrants (as defined in Section 4.5) or other rights to
                  acquire Panopticon capital stock outstanding (whether or not
                  vested or exercisable), and those which Panopticon has
                  promised to grant or to recommend to the Panopticon board of
                  directors to grant, as of the date of this Agreement; and

                                                     (2) "CONVERSION RATIO"
                  means the quotient (calculated to the fourth decimal place)
                  obtained by dividing the Total Merger Consideration by the
                  Panopticon Share Number;

              provided that, absent the express written consent of Broadbase
              (for example, with respect to new option grants pursuant to
              Section 6.4), in no event shall Broadbase issue more than
              3,179,810 shares of Broadbase common stock in connection with the
              Merger (including shares issuable upon exercise or conversion of
              Exchange Options and Exchange Warrants). Each outstanding share of
              Panopticon preferred stock will be converted to Panopticon common
              stock at the then-applicable conversion ratio prior to the
              Effective Time, and will be deemed to have been converted to
              Panopticon common stock prior for purposes of calculating the
              Conversion Ratio. Each share of Panopticon common stock owned by
              Panopticon immediately prior to the Effective Time shall be
              canceled and extinguished without any conversion pursuant to this
              Section 2.2.

                                            (B) Any right of repurchase by
              Panopticon of any shares of Panopticon common stock that exists
              immediately before the Effective Time shall continue and become a
              right of Broadbase to repurchase on the same terms and conditions
              (adjusted according to the Conversion Ratio) as the applicable
              Exchange Shares, except, with respect to Exchange Shares issued to
              those persons listed in Schedule 2, as explicitly set forth in the
              Employment Agreements. Except for shares of Panopticon common
              stock held by Gerald Held and Lee Kennedy, no right of repurchase
              shall lapse as a result of the Merger, and if any holder of
              restricted stock has acceleration provisions that would be
              triggered by the Merger, each such holder, other than Mr. Held or
              Ms. Kennedy, will waive such acceleration provisions.

                                      -4-
<PAGE>   5

                                    (iii) Dissenting Shares. Holders of shares
         of Panopticon common stock who have complied with all requirements for
         perfecting stockholders' rights of appraisal, as set forth in Section
         1300 of the California Corporations Code, shall be entitled to their
         rights under California law with respect to such rights.

                                    (iv) Assumption and Conversion of Panopticon
         Options.

                                            (A) Effective at the Effective Time,
              Broadbase will assume all Panopticon Options, and each of the
              Panopticon Options shall by its terms be converted into an option
              to purchase that number of shares of Broadbase common stock (an
              "EXCHANGE OPTION") which equals the number of shares of Panopticon
              common stock subject to the Panopticon Option immediately prior to
              the Effective Time, multiplied by the Conversion Ratio, rounded
              down to the nearest whole share. The per share exercise price for
              each Exchange Option will equal the per share exercise price of
              each such Panopticon Option immediately prior to the Effective
              Time divided by the Conversion Ratio, rounded up to the nearest
              whole cent. No cash will be paid in lieu of fractional shares
              which are rounded down pursuant to this Section 2.1(a)(iv)(A). No
              Exchange Options or Exchange Shares shall be issued with respect
              to Panopticon Options which are cancelled subsequent to the date
              of this Agreement and prior to the Effective Time.

                                            (B) Terms of Assumption of Stock
              Options; Vesting. The term, exercisability, vesting schedule,
              status as an "incentive stock option" under Section 422 of the
              Code, if applicable, and all other terms of each Exchange Option
              will be the same in all material respects as the corresponding
              Panopticon Option, except, with respect to Exchange Options
              granted to those persons listed in Schedule 2, as explicitly set
              forth in the Employment Agreements; provided, however, that if the
              employment of a holder of Exchange Options (other than those
              listed in Schedule 2) is terminated (1) by Broadbase without
              "cause" (as such term is defined in the form of Employment
              Agreement attached hereto), (2) by such holder, after
              "Constructive Termination" (as such term is defined in the form of
              Employment Agreement attached hereto) by Broadbase without cause,
              or (3) due to the death or disability of such holder, then upon
              such termination any unvested Exchange Options held by such holder
              which are subject to cliff vesting as of the time of such
              termination shall become vested and exercisable with respect to
              the number of shares that would have vested on a monthly basis
              during such period in accordance with the monthly vesting schedule
              to take effect following such cliff period. No vesting of shares
              subject to Panopticon Options will be accelerated as a result of
              the Merger and if any holder of Panopticon Options has
              acceleration provisions that would be triggered by the Merger,
              each such holder will waive such acceleration provisions.
              Continuous employment with Panopticon will be credited to holders
              of Panopticon Options for purposes of determining the number of
              Exchange Shares exercisable after the Effective Time.

                                    (v) Assumption and Conversion of Panopticon
         Warrants. Effective at the Effective Time, Broadbase will assume all
         Panopticon Warrants, and each of the Panopticon Warrants shall by its
         terms be converted into a warrant to purchase that number of shares of
         Broadbase common stock (an "EXCHANGE WARRANT") which equals the number
         of shares of Panopticon common stock subject to the Panopticon Warrant
         immediately prior to the Effective Time, multiplied by the Conversion
         Ratio, rounded down to the nearest whole share. The per share exercise
         price for each Exchange Warrant will equal the per share exercise price
         of each such Panopticon Warrant immediately prior to the Effective Time
         divided by the


                                      -5-
<PAGE>   6

         Conversion Ratio, rounded up to the nearest whole cent. No cash will be
         paid in lieu of fractional shares which are rounded down pursuant to
         this Section 2.1(a)(v)(A). The term, exercisability, vesting schedule,
         and all other terms of each Exchange Warrant will be the same in all
         material respects as the corresponding Panopticon Warrant. No Exchange
         Warrants or Exchange Shares shall be issued with respect to the
         Panopticon Warrant held by Kindling I LLC issued August 15, 1999 (with
         respect to the remaining shares subject to such warrant) and all other
         Panopticon Warrants which, by their terms, will never become
         exercisable (the "NON-EXERCISABLE PANOPTICON WARRANTS").

                                    (vi) Adjustment for Capital Changes. If
         prior to the Merger, Broadbase (A) recapitalizes either through a
         split-up of the outstanding shares of Broadbase common stock into a
         greater number, or through a combination of such outstanding shares
         into a lesser number, (B) reorganizes, reclassifies or otherwise
         changes such outstanding shares into the same or a different number of
         shares of other classes or into securities of another company (other
         than through a split-up or combination of shares provided for in the
         previous clause), or (C) declares a dividend on its outstanding shares
         payable in shares or securities convertible into shares, the
         calculation of the Conversion Ratio and the Escrow Shares (as defined
         in Section 2.2(b)) will be adjusted appropriately so as to maintain the
         proportionate interests of the Panopticon Shareholders and the holders
         of Broadbase common Stock at the time of such recapitalization.

                                    (vii) Fractional Shares. No fractional
         shares of Broadbase common stock will be issued in connection with the
         Merger. However, in lieu thereof, each Panopticon Shareholder who would
         otherwise be entitled to receive a fraction of a share of Broadbase
         common stock (excluding with respect to Panopticon Options and
         Panopticon Warrants) will receive from Broadbase an amount of cash
         equal to the product obtained by multiplying (A) the closing price of a
         share of Broadbase common stock on the Nasdaq National Market on the
         last trading day before the Effective Time by (B) the fraction of a
         share of Broadbase common stock that such holder would otherwise have
         been entitled to receive.

                           (b) Effects of the Merger. At the Effective Time: (i)
     Merger Sub will merge with and into Panopticon, Panopticon will be the
     Surviving Corporation pursuant to the terms of the Agreement of Merger and
     the Certificate of Merger and the separate existence of Merger Sub will
     thereupon cease; (ii) each share of Panopticon capital stock outstanding
     immediately prior to the Effective Time will be converted as provided in
     this Section 2.1, subject to the escrow provisions of Section 2.2; (iii)
     each share of common stock of Merger Sub that is issued and outstanding
     immediately prior to the Effective Time will, by virtue of the Merger and
     without further action on the part of the sole stockholder of Merger Sub,
     be converted into and become one share of common stock of the Surviving
     Corporation (and the shares of Surviving Corporation into which the shares
     of Merger Sub common stock are so converted shall be the only shares of
     Panopticon common stock that are issued and outstanding immediately after
     the Effective Time); (iv) the Articles of Incorporation and Bylaws of
     Panopticon shall be amended and restated to contain provisions in
     substantially the form set forth in the Certificate of Incorporation and
     Bylaws of Merger Sub; (v) the Board of Directors and executive officers of
     Broadbase will remain unchanged and the sole director and officers of
     Merger Sub immediately prior to the Effective Time will become the sole
     director and officers of the Surviving Corporation; and (vi) the Merger
     will, from and after the Effective Time, have all of the effects provided
     by applicable law.

                  2.2      Escrow.

                           (a) Escrow Agent. State Street Bank and Trust Company
     of California, N.A., or such other escrow agent selected by Broadbase prior
     to the Closing (the "ESCROW AGENT") shall hold, release and perform other
     tasks related to the Escrow Shares (defined in Section 2.2(b)) pursuant to
     the provisions of the Escrow Agreement.

                           (b) Escrow Shares. Broadbase will deduct, on a pro
     rata basis from the number of Exchange Shares to be issued to each
     Panopticon Shareholder pursuant to Section 2.1(a)(ii) upon surrender of his
     or her Panopticon Certificates, that number of shares of Broadbase common
     stock equal to ten percent (10%) of the shares of Broadbase common stock
     issuable in the Merger to the holders of Panopticon common stock
     immediately prior to the Effective Time, rounded to the nearest whole share
     (the "ESCROW SHARES"). As soon as practicable after the Effective Time, and
     in accordance with the provisions of the Escrow Agreement, Broadbase will
     deposit with the Escrow Agent certificates representing the Escrow Shares,
     issued in the name of each Panopticon Shareholder, together with related
     stock transfer powers. Stock dividends that are issued in order to effect a
     stock split of Broadbase common stock on Escrow Shares paid during the
     Escrow Period shall also be held in escrow until such Escrow Shares are
     released.

                           For the purposes of this Agreement and the Escrow
     Agreement, Escrow Shares will be deemed to have a per share value equal to
     the closing price per share of Broadbase common stock as quoted on the
     Nasdaq National Market, and reported in The Wall Street Journal, for the
     trading day immediately preceding the Closing Date (such price shall be
     subject to adjustment to reflect any capital change of the type referred to
     in Section 2.1(a)(v), whether occurring at or after the Effective Time, and
     Broadbase shall promptly provide the Escrow Agent with written notice of
     such capital change) as provided in the Escrow Agreement.

                           (c) Escrow Period. The Escrow Agent will hold the
     Escrow Shares and dividends as collateral for Panopticon's indemnification
     obligations and release shares to satisfy valid claims, all pursuant to the
     Escrow Agreement and Article 12 of this Agreement. The Escrow Agent will
     continue to hold Escrow Shares and dividends not released in satisfaction
     of claims until the end of the Escrow Period.

                  2.3      Securities Law Compliance and Contractual
                           Restrictions.

                           (a) Issuance of Exchange Shares in Exchange for
     Panopticon Common Stock. The parties to this Agreement intend that
     Broadbase shall issue the Exchange Shares pursuant to a permit obtained
     pursuant to a California fairness hearing under Section 3(a)(10) of the
     Securities Act, or, if Broadbase and Panopticon are unable to obtain such a
     permit after using reasonable best efforts to do so, pursuant to a "private
     placement" under Regulation D and/or Section 4(2) of the Securities Act and
     applicable state securities laws (the "PRIVATE PLACEMENT EXEMPTION"). In
     the event that a permit is not obtained and the Exchange Shares are issued
     pursuant to the Private Placement Exemption, the parties agree to cooperate
     in good faith to negotiate and enter into, and cause the Panopticon
     Shareholders to enter into, a registration rights agreement providing for
     the terms set forth in Section 2.3(c)(ii).

                           (b) Issuance of Exchange Shares Pursuant to Exercises
     of Exchange Options. Broadbase shall cause the Exchange Shares that are
     issuable upon exercise of the Exchange Options to be registered under the
     Securities Act on Form S-8 or any other applicable form within a


                                      -7-
<PAGE>   8

     reasonable time after the Closing Date (and in any event within 30 days
     following the Closing Date). Broadbase will use commercially reasonable
     efforts to maintain the effectiveness of such registration statement so
     long as the Exchange Options and New Options (or shares issued upon
     exercise thereof) remain outstanding.


                           (c) Securities Law Restrictions on Resale of Exchange
     Shares.

                                    (i) Fairness Hearing. In the event that the
         Exchange Shares are issued pursuant to a permit obtained pursuant to a
         California fairness hearing as provided above, the Exchange Shares will
         be freely tradable, subject to (A) with respect to the persons listed
         on Schedule 2, the contractual resale restrictions or repurchase rights
         set forth in their Employment Agreements with Broadbase, (B) such
         restrictions imposed by the Securities Act (including Rule 145
         promulgated thereunder) on stockholders who are former affiliates of
         Panopticon or who become affiliates of Broadbase following the Merger,
         (C) the extent of any repurchase rights assumed by Broadbase with
         respect to any such Exchange Shares which are unvested, and (D)
         compliance with any securities trading policies of Broadbase that are
         applicable to its officers and/or employees. In this circumstance,
         Broadbase will not be under any obligation to register the offer and
         sale of the Exchange Shares (other than those issued upon the exercise
         of Exchange Options) with the Commission under the Securities Act.

                                    (ii) Private Placement. In the event that
         the Exchange Shares are issued pursuant to Private Placement Exemption:

                                            (A) Restricted Securities. The
              Exchange Shares shall constitute "restricted securities" within
              the meaning of the Securities Act. The certificates for Exchange
              Shares to be issued in the Merger shall bear appropriate legends
              to identify such privately placed shares as being restricted under
              the Securities Act, to comply with applicable state securities
              laws.

                                            (B) S-3 Registration Rights. Within
              15 days after Broadbase becomes eligible to use such form under
              the Securities Act, Broadbase shall file with the Commission a
              shelf registration statement on Form S-3 to provide for the resale
              of the Exchange Shares. Notwithstanding the foregoing, if
              Broadbase is not eligible to use such form as of September 30,
              2000, then Broadbase will instead use its best efforts to file
              with the Commission a registration statement on Form S-1 to
              provide for resale of the Exchange Shares on or before October 15,
              2000. Broadbase will keep such registration statement effective
              for a period of one year after the Effective Time, in accordance
              with the terms and conditions of the registration rights
              agreement.

                                            (C) Piggyback Registration Rights.
              Broadbase shall notify all holders of Exchange Shares in writing
              at least thirty (30) days prior to filing any registration
              statement under the Securities Act for purposes of effecting a
              public offering of Broadbase securities (including, but not
              limited to, registration statements relating to secondary
              offerings of Broadbase securities, but excluding registration
              statements relating to any employee benefit plan or a corporate
              reorganization) and will afford each such holder an opportunity to
              include in such registration statement all or any part of the
              Exchange Shares then held by such holder. Each holder desiring to
              include in any such registration statement all or any part of the
              Exchange Shares held by such holder shall, within twenty (20) days
              after receipt of the above-described notice from Broadbase, so
              notify Broadbase in writing,



                                      -8-
<PAGE>   9

              and in such notice shall inform Broadbase of the number of
              Exchange Shares such holder wishes to include in such
              registration statement. The rights pursuant to this Section
              2.3(c)(ii)(C) shall terminate and have no force and effect
              upon the declaration by the Commission of the effectiveness of
              a registration statement on Form S-3 filed by Broadbase
              providing for the resale of the Exchange Shares.

                           (d) Holders of Exchange Shares will be wholly
     responsible for compliance with all federal and state securities laws
     regarding the sale, transfer or other disposition of such shares.

                  2.4      Tax and Accounting Aspects of the Merger.

                           (a) Tax Free Reorganization. The parties intend to
     adopt this Agreement as a tax-free plan of reorganization and to consummate
     the Merger in accordance with the provisions of Section 368(a)(1)(A) and
     Section 368(a)(2)(E) of the Code. The parties to this Agreement hereby
     adopt this Agreement as a "plan of reorganization" within the meaning of
     Sections 1.368-2(g) and 1.368-3(a) of the United States Treasury
     Regulations. The value of the Exchange Shares and Exchange Options to be
     received in the Merger is approximately equal, in each instance, to the
     value of the Panopticon common stock and Panopticon Options to be
     surrendered in exchange therefor. The Exchange Shares issued in the Merger
     will be issued solely in exchange for the Panopticon common stock or upon
     exercise of Exchange Options, and no other transaction other than the
     Merger represents, provides for or is intended to be an adjustment to, the
     consideration paid for the Panopticon common stock and Panopticon Options.
     Except for any cash paid in lieu of fractional shares, no consideration
     that could constitute "other property" within the meaning of Section 356 of
     the Code is being paid by Broadbase for the Panopticon common stock and
     Panopticon Options in the Merger. The parties shall treat the Merger as a
     tax-free reorganization described in Section 368(a)(2)(E) of the Code and
     shall not take any position on any tax returns or for any federal income
     tax purposes that is inconsistent with such treatment or is inconsistent
     with this Section 2.4(a). In addition, Broadbase represents that it
     presently intends, and covenants that at the Effective Time it will intend,
     to continue Panopticon's historic business or use a significant portion of
     Panopticon's business assets in a business.

                           (b) Accounting Treatment. The parties intend that the
     Merger be treated as a "purchase" for accounting purposes.

                  2.5 Antitrust. Each of Broadbase and Panopticon will promptly
prepare and file the applicable notices (if any) required to be filed by it
under the Hart-Scott-Rodino Antitrust Improvements Act of 1976 (the "HSR ACT"),
and comply promptly with any requests to it from the Federal Trade Commission or
United States Department of Justice for additional information.

                  2.6 Further Assurances. Panopticon agrees that if, at any time
before or after the Effective Time, Broadbase considers or is advised that any
further deeds, assignments or assurances are reasonably necessary or desirable
to vest, perfect or confirm in Broadbase title to any property or rights of
Panopticon or the Surviving Corporation as provided herein, Broadbase, the
Surviving Corporation and their proper officers and directors are hereby
authorized by Panopticon to execute and deliver all such proper deeds,
assignments and assurances and do all other things necessary or desirable to
vest, perfect or confirm title to such property or rights in Broadbase and
otherwise to carry out the purpose of this Agreement, in the name of Panopticon
or otherwise. The officers and directors of Broadbase, Panopticon and Merger Sub
will take all such other lawful and necessary or desirable action to carry out
the purposes of this Agreement.

         3.       ADDITIONAL AGREEMENTS


                  3.1 Public Announcement. Broadbase and Panopticon will issue a
press release approved by both parties announcing the Merger as soon as
practicable following the execution of this Agreement. Each of Broadbase and
Panopticon may issue such press releases, and make such other disclosures
regarding the Merger, as it determines to be required or appropriate under
applicable securities laws or Nasdaq Stock Market rules after reasonable
consultation, where possible, with the other. Panopticon will not make any other
public announcement or disclosure of the transactions contemplated by this
Agreement. Panopticon will take all reasonable precautions to prevent any
trading in the securities of Broadbase by officers, directors, employees and
agents of Panopticon, having knowledge of any material information regarding
Broadbase provided hereunder, including, without limitation, the existence of
the transactions contemplated by this Agreement until the information in
question has been publicly disclosed.

                  3.2 Fees and Expenses. Except as set forth in this Section
3.3, each party will bear its respective expenses and fees of its own
accountants, attorneys, investment bankers and other professionals incurred with
respect to this Agreement and the transactions contemplated hereby. If the
Merger is consummated, Broadbase will pay at or immediately following the
Closing the reasonable investment banking, accounting and attorneys' fees and
expenses and other fees and expenses incurred by Panopticon in connection with
the Merger, not to exceed more than $235,000.

                  3.3 Integration Matters. Panopticon and Broadbase will
cooperate in good faith to identify and, to the extent practicable, to resolve
matters regarding the orderly integration of their respective operations.


         4.       REPRESENTATIONS AND WARRANTIES OF PANOPTICON

                  Except as set forth in the Panopticon Disclosure Letter, the
parts of which are numbered to correspond to the section numbers of this
Agreement, Panopticon hereby represents and warrants to Broadbase as follows:

                  4.1 Organization and Good Standing. Panopticon is a
corporation duly organized, validly existing and in good standing under the laws
of the state of its incorporation and is qualified as a foreign corporation in
each other jurisdiction (as listed under Item 4.1 of the Panopticon Disclosure
Letter) in which a failure to be so qualified could reasonably be expected to
have a Material Adverse Effect on Panopticon.

                  4.2      Power, Authorization and Validity.

                           (a) Panopticon has the corporate power and authority
     to: (i) carry on its business as now conducted and as proposed to be
     conducted; (ii) own, operate and lease its properties in the manner in
     which its properties are currently owned, used and leased and in the manner
     in which its properties are proposed to be owned, used and leased; (iii)
     perform its obligations under all Panopticon Contracts, and (iv) enter into
     and perform its obligations under this Agreement and all agreements to
     which Panopticon is or will be a party that are required to be executed
     pursuant to or in connection with this Agreement (the "PANOPTICON ANCILLARY
     AGREEMENTS"). The execution, delivery and performance of this Agreement and
     the Panopticon Ancillary Agreements has been duly and validly approved by
     the unanimous vote of the Panopticon Board of Directors.

                                      -10-
<PAGE>   11

                           (b) No filing, authorization or approval,
     governmental or otherwise, is necessary to enable Panopticon to enter into
     and to perform its obligations under this Agreement and the Panopticon
     Ancillary Agreements, except for (i) the filing of the Agreement of Merger
     and the Certificate of Merger with the Secretaries of State of the State of
     California and Delaware, respectively, the filing of such officers'
     certificates and other documents as are required to effectuate the Merger
     under California and Delaware law and the filing of appropriate documents
     with the relevant authorities of the states other than California in which
     Panopticon is qualified to do business, if any, (ii) such filings as may be
     required to comply with federal and state securities laws, including the
     Permit Application (as defined in Section 6.5), (iii) the approval of the
     holders of at least a majority of the outstanding shares of Panopticon
     common stock and two-thirds of the outstanding shares of Panopticon
     preferred stock of the Merger, this Agreement and related transactions
     contemplated hereby, and (iv) such filings as may be required by the HSR
     Act. As of the date hereof, the Panopticon Shareholders who have executed
     Voting Agreements collectively own shares of Panopticon Common Stock and
     Panopticon Preferred Stock representing, in the aggregate, voting power
     sufficient to approve the Merger, this Agreement and the related
     transactions contemplated hereby.

                           (c) This Agreement and the Panopticon Ancillary
     Agreements are, or when executed and delivered by Panopticon and the other
     parties thereto will be, valid and binding obligations of Panopticon
     enforceable against Panopticon in accordance with their respective terms,
     except as to the effect, if any, of (i) applicable bankruptcy and other
     similar laws affecting the rights of creditors generally, (ii) rules of law
     governing specific performance, injunctive relief and other equitable
     remedies and (iii) the enforceability of provisions requiring
     indemnification; provided, however, that the Certificate of Merger, the
     Agreement of Merger and the Panopticon Ancillary Agreements will not be
     effective until the earlier of the Effective Time and the date provided for
     therein.

                  4.3 No Violation of Charter Documents, Contracts or Laws.
Neither the execution and delivery of this Agreement or any Panopticon Ancillary
Agreement, nor the consummation of the transactions provided for herein or
therein, will conflict with, or (with or without notice or lapse of time, or
both) result in a termination, breach, impairment or violation of, (a) any
provision of the Certificate of Incorporation, Bylaws or other charter documents
of Panopticon, as currently in effect, (b) any material Panopticon Contract, or
(c) any federal, state, local or foreign judgment, writ, decree, order, statute,
rule or regulation applicable to Panopticon or its assets or properties. The
consummation of the Merger and succession by Broadbase to all rights, licenses,
franchises, leases and agreements of Panopticon will not require the consent of
any third party (except as set forth under Item 4.3 of the Panopticon Disclosure
Letter) and will not have a Material Adverse Effect on Panopticon.

                  4.4      Corporate Documents.

                           (a) Panopticon has made available to Broadbase for
     examination all documents and information listed in the Panopticon
     Disclosure Letter or other exhibits called for by this Agreement,
     including, without limitation, the following: (i) copies of Panopticon's
     Articles of Incorporation, Bylaws and other charter documents, as currently
     in effect; (ii) Panopticon's minute book containing all records of all
     proceedings, consents, actions and meetings of the shareholders, the Board
     of Directors and any committees of the Board of Directors of Panopticon;

     stock issuances and transfers; and (iv) all permits, orders and consents

     consents.

<PAGE>   12

                           (b) There has not been any violation of any of the
     provisions of the Panopticon Articles of Incorporation or Panopticon
     bylaws, and to Panopticon's knowledge, no event has occurred, and no
     condition or circumstance exists, that likely would (with or without notice
     and/or lapse of time) constitute or result directly or indirectly in such a
     violation.

                           (c) The books of account, stock records, minute books
     and other records of Panopticon (i) are in all material respects true and
     complete, (ii) have been maintained in accordance with reasonable business
     practices and (iii) accurately and fairly reflect in all material respects
     the transactions and dispositions of the assets of Panopticon.

                  4.5      Capitalization.

                           (a) Authorized/Outstanding Capital Stock. As of the
     date hereof, the authorized capital stock of Panopticon consists solely of
     10,000,000 shares of Panopticon common stock and 2,500,000 shares of

     A Preferred Stock (each of which is convertible into one share of
     Panopticon common stock). All issued and outstanding shares of Panopticon
     common stock and Panopticon preferred stock have been duly authorized and
     validly issued, are fully paid and nonassessable, are not subject to any
     right of rescission and have been offered, issued, sold and delivered by
     Panopticon in compliance with all registration or qualification
     requirements (or applicable exemptions therefrom) of applicable federal and
     state securities laws. A list of all holders of Panopticon capital stock
     and the number of shares held by each is set forth under Item 4.5(a) of the
     Panopticon Disclosure Letter as of the date hereof, to be updated as of the
     Closing Date.

                           (b) Options/Warrants/Rights. As of the date of this

     stock (the "PANOPTICON OPTIONS") have been issued and are outstanding; (ii)
     warrants to purchase 350,000 shares of Panopticon common stock have been
     issued and are outstanding; and (iii) warrants to purchase 186,487 shares
     of Panopticon Series A Preferred Stock have been issued and are outstanding
     (the warrants in (ii) and (iii) are collectively referred to as the
     "PANOPTICON WARRANTS"). A list of all holders of Panopticon Options and
     Panopticon Warrants is set forth under Item 4.5(b) of the Panopticon
     Disclosure Letter. Item 4.5(b) of the Panopticon Disclosure Letter lists

     exercise price for each such Panopticon Option or Panopticon Warrant, the
     number of shares or other securities covered by each such Panopticon Option
     or Panopticon Warrant, the term of exercisability of each such Panopticon
     Option or Panopticon Warrant, the vesting schedule and the extent each such
     Panopticon Option or Panopticon Warrant is vested as of the date hereof. In
     addition, Item 4.5(b) of the Panopticon Disclosure Letter lists all holders
     of unvested shares of Panopticon common stock and for each such person, the
     number of unvested shares of Panopticon common stock held and the vesting
     schedule. Panopticon has delivered to Broadbase accurate and complete
     copies of all plans pursuant to which Panopticon has ever granted stock

     Disclosure Letter, there is no: (i) outstanding preemptive right, stock
     appreciation right, subscription, option, call, warrant or right (whether

     Panopticon's knowledge, from affiliates of Panopticon, any shares of the
     capital stock or other securities of Panopticon; (ii) outstanding security,
     instrument or obligation issued by Panopticon or controlled affiliates of
     Panopticon, that is or may become convertible into or exchangeable for any

     shareholders' rights plan (or similar plan

                                      -12-

     commonly referred to as a "poison pill") or Contract under which
     Panopticon is or may become obligated to sell or otherwise
     issue any shares of its capital stock or any other securities; (iv)
     Contract to which Panopticon is a party relating to the voting or
     registration of or restricting any person from purchasing, selling,
     pledging or otherwise disposing of (or granting any option or similar right
     with respect to) any shares of Panopticon common stock; (v) liability for
     dividends accrued but unpaid; or (vi) condition or circumstance, to
     Panopticon's knowledge, that likely would directly or indirectly give rise
     to or provide a basis for the assertion of a claim by any person to the
     effect that such person is entitled to acquire or receive any shares of
     capital stock or other securities of Panopticon, including but not limited
     to promises to issue or grant securities of Panopticon or to recommend to
     Panopticon's board of directors to issue or grant securities of Panopticon.

                           (c) Panopticon is not under any obligation to
     register under the Securities Act any of its presently outstanding
     securities or any securities that may be subsequently issued.

                           (d) To Panopticon's knowledge (i) each Panopticon
     Shareholder has valid title to the shares of Panopticon common stock to be
     sold by such shareholder as set forth under Item 4.5(d) of the Panopticon
     Disclosure Letter, and the legal right and power, and all authorizations
     and approvals required by law, to enter into this Agreement, and to sell,
     transfer and deliver the shares to be sold by such shareholder; (ii) no
     Panopticon Shareholder has sold, assigned or otherwise transferred to any
     third party any of his or her right, title or interest in or to any of the
     shares of Panopticon common stock set forth as owned by such shareholder on
     Item 4.5(d); and (iii) there exists no pledge, lien, security interest,
     claim or encumbrance whatsoever on or relating to any of the shares of
     Panopticon common stock set forth as owned by such shareholder on Item
     4.5(d). To Panopticon's knowledge, (i) no Panopticon Shareholder has
     claimed any interest in any additional shares of capital stock of
     Panopticon, or any options, warrants or other securities of Panopticon,
     except for the number of shares of Panopticon common stock which such
     person is shown to be the owner of on Item 4.5(d), and (ii) no third party
     who is not listed on Item 4.5(d) has made, or has, any claim of entitlement
     to receive any shares of the capital stock of Panopticon, any warrants or
     other rights to acquire any capital stock of Panopticon or any other
     securities of Panopticon.

                  4.6 Board of Directors, Officers and Key Personnel. Item 4.6

title of each of Panopticon's officers; (b) the name and title of supervisory,
developmental or other key personnel of Panopticon; and (c) the name, principal
occupation and address of each member of Panopticon's board of directors.

                  4.7 Subsidiaries and Guaranties. Panopticon does not have any
equity interest, direct or indirect, in any corporation, partnership, joint
venture or other business entity. Panopticon is not a guarantor of any
obligation of a third party, whether or not such third party is related to or
affiliated with Panopticon.

                  4.8 Litigation. There is no action, suit, arbitration,
mediation, proceeding, claim or, to Panopticon's knowledge, investigation
pending against Panopticon, nor, to Panopticon's knowledge, are any of the
foregoing threatened against Panopticon before any court, administrative agency
or arbitrator that, if determined adversely to Panopticon, may reasonably be
expected to have a Material Adverse Effect on Panopticon. There is no judgment,
decree, injunction, rule or administrative agency or arbitrator outstanding
against Panopticon. To the knowledge of Panopticon, there is no basis for any
person, firm, corporation or entity to assert a claim against Panopticon, or
Broadbase as successor in interest to Panopticon, based upon: (a) ownership or
rights to ownership of any shares of Panopticon common stock or other
securities, (b) any rights as a Panopticon securities holder, including, without

                                      -13-

limitation, any option, warrant or other right to acquire any Panopticon
securities, any preemptive rights or any rights to notice or to vote, or (c) any
rights under any agreement between Panopticon and any Panopticon securities
holder or former Panopticon securities holder in such holder's capacity as such.
There is no action, suit, proceeding, claim, arbitration or investigation
pending as to which Panopticon has received notice of assertion against
Panopticon, which in any manner challenges or seeks to prevent, enjoin, alter or
materially delay any of the transactions contemplated by this Agreement.

                  4.9 Panopticon Financial Statements. Panopticon has delivered
to Broadbase, attached hereto as Exhibit E, Panopticon's unaudited balance sheet
as of December 31, 1998 and 1999 and its unaudited balance sheet as of May 31,
2000 (the "BALANCE SHEET DATE"), Panopticon's unaudited income statements and
cash flows for the years ended December 31, 1998 and 1999 and its unaudited
income statement and cash flow for the period from January 1, 2000 through May
31, 2000 (collectively, the "PANOPTICON FINANCIAL STATEMENTS"). Except as
disclosed under Item 4.9 of the Panopticon Disclosure Letter, the Panopticon
Financial Statements: (a) are in accordance with the books and records of
Panopticon, (b) present fairly and accurately the financial condition of
Panopticon at the respective dates specified therein and the results of
operations for the respective periods specified therein in accordance with GAAP
and (c) have been prepared in accordance with GAAP applied on a consistent basis
(except for the absence of any footnotes required by GAAP in the Financial
Statements and subject to customary year-end adjustments). In the opinion of
management of Panopticon, the Financial Statements include all adjustments,
consisting only of normal recurring adjustments, necessary for a fair
presentation of the financial position and results of operations of Panopticon
for the unaudited interim period. Panopticon has no material debt, liability or
obligation of any nature, whether accrued, absolute, contingent or otherwise,
and whether due or to become due, that is not reflected, reserved against or
disclosed in the Panopticon Financial Statements or under Item 4.9 of the
Panopticon Disclosure Letter, except for those that may have been incurred after
the Balance Sheet Date in the ordinary course of Panopticon's business,
consistent with past practice and that are in an aggregate amount not to exceed
$50,000.

                  4.10     Taxes.

                           (a) For the purposes of this Section 4.10, the terms
     "TAX" and "TAXES" include all federal, state, local and foreign income,
     gains, franchise, excise, property, sales, use, employment, license,
     payroll, occupation, recording, value added or transfer taxes, governmental
     charges, fees, levies or assessments (whether payable directly or by
     withholding), and, with respect to such taxes, any estimated tax, interest
     and penalties or additions to tax and interest on such penalties and
     additions to tax.

                           (b) Except as set forth in Item 4.10(b) of the
     Panopticon Disclosure Letter, Panopticon has filed all federal, state,
     local and foreign tax and material information returns required to be filed
     prior to the date hereof, has paid all taxes required to be paid in respect
     of all periods prior to the date hereof for which returns have been filed,
     has made all necessary estimated tax payments, and has no material
     liability for taxes in excess of the amount so paid, except to the extent
     adequate reserves have been established in the Panopticon Financial
     Statements. True, correct and complete copies of all such tax and
     information returns for the past two years have been provided or made
     available by Panopticon to Broadbase. Panopticon is not delinquent in the
     payment of any tax or in the filing of any tax returns, and no deficiencies
     for any tax have been threatened, claimed, proposed or assessed which have
     not been settled or paid. No tax return of Panopticon has ever been audited
     by the Internal Revenue Service or any state taxing agency or authority.
     Panopticon does not have any current or deferred federal income tax
     liabilities and will not as a result of the Merger become

                                      -14-
<PAGE>   15

     liable for any income tax not adequately reserved against on the
     Panopticon Financial Statements. Panopticon has not filed a consent
     pursuant to Section 341(f) of the Code.

     (c) No benefit payable or which may become payable by Panopticon pursuant
     to any Panopticon Employee Plan (as defined in Section 4.17(c) or any
     Panopticon Benefit Arrangement (as defined in Section 4.17(e) or as a
     result of or arising under this Agreement shall constitute an "excess
     parachute payment" (as defined in Section 280G(b)(1) of the Code) which is
     subject to the imposition of an excise tax under Section 4999 of the Code
     or which would not be deductible by reason of Section 280G of the Code.

                  4.11     Title to Properties.

                           (a) Panopticon has good and marketable title to all
     of its assets as shown on the balance sheet as of the Balance Sheet Date
     included in the Panopticon Financial Statements, free and clear of all
     liens, charges or encumbrances (other than for taxes not yet due and
     payable). Except as set forth under Item 4.11 of the Panopticon Disclosure
     Letter, there are no UCC financing statements of record with any state
     naming Panopticon as debtor and Panopticon does not own any property in any
     other state. The machinery and equipment included in the assets of
     Panopticon is in all material respects in good condition and repair, normal
     wear and tear excepted, and all leases of real or personal property to
     which Panopticon is a party are fully effective and afford Panopticon
     peaceful and undisturbed possession of the subject matter of the lease. To
     its knowledge, Panopticon is not in violation of any zoning, building,
     safety or environmental ordinance, regulation or requirement or other law
     or regulation applicable to the operation of owned or leased properties,
     and Panopticon has not received any notice of such violation with which it
     has not complied or had waived.

                           (b) Panopticon owns no real property, nor has it ever
     owned any real property. All leases of real or personal property to which
     Panopticon is a party are fully effective and afford Panopticon peaceful
     and undisturbed possession of the subject matter of the lease. The
     Surviving Corporation will obtain a valid ownership or leasehold interest
     in all such personal property that Panopticon currently owns or leases and
     all real property that Panopticon currently leases, as of the date of this
     Agreement, in each case free and clear of all title defects and
     encumbrances of any kind, except: (i) mechanics', carriers', workers' and
     other similar liens arising in the ordinary course of business, and (ii)
     liens for current taxes not yet due and payable.

                  4.12 Absence of Certain Changes or Events. Since the Balance
Sheet Date, Panopticon has carried on its business in the ordinary course
substantially in accordance with the procedures and practices in effect on the
Balance Sheet Date.

                           (a) Except as set forth under Item 4.12 of the

         circumstance or effect on the business, prospects, assets or
         liabilities (including intangible assets), capitalization, financial
         condition or results of operations of Panopticon, which by itself or in
         conjunction with all other such changes, whether or not arising in the
         ordinary course of business, has had or can reasonably be expected to
         have a Material Adverse Effect on Panopticon;

                                      -15-

         others which exceed in the aggregate $100,000;

         the ordinary course of business and consistent with past practice;

                                    (vi) any material damage, destruction or

         labor practices;

                                    (viii) any change in the compensation

         or agents earning compensation at an anticipated annual rate in excess
         of $50,000, or any bonus payment or arrangement made to or with any of
         such officers, employees, consultants or agents; or any change in the
         compensation payable or to become payable to any of Panopticon's other

         with past practice) or any bonus payment or arrangement made to or with
         any of such officers, employees or agents other than normal bonuses or

effect, and except as expressly noted, a true and complete copy of each has been
delivered or made available to Broadbase. Except as noted on Item 4.13, neither
Panopticon nor, to the knowledge of Panopticon, any other party is in material
breach of or default under any material term of any such agreement, obligation
or commitment. Panopticon has no liability for renegotiation of government
Contracts or sub-Contracts which are material to Panopticon, its financial
condition, business or prospects.

                  4.14     Intellectual Property.

                           (a) Definition. As used herein, the term
     "INTELLECTUAL PROPERTY RIGHTS" shall mean all worldwide industrial and
     intellectual property rights, including, without limitation, patents,
     patent applications, patent rights, trademarks, trademark applications,
     trade names, service marks, service mark applications, URLs, copyright,
     copyright applications, franchises, licenses, inventories, know-how, trade
     secrets, customer lists, proprietary processes and formulae, all source and
     object code, algorithms, architecture, structure, display screens, layouts,
     inventions, development tools and all documentation and media constituting,
     describing or relating to the above, including, without limitation,
     manuals, memoranda and records.

                           (b) Ownership of Intellectual Property. Panopticon
     owns all right, title and interest in, or has the right to use, all
     Intellectual Property Rights used in or reasonably necessary to the conduct
     of its business as presently conducted and the business of the licensing
     and use of Panopticon products and the sale of commercial services using
     such intellectual property and proprietary rights ("PANOPTICON IP RIGHTS").
     Panopticon has the unrestricted, worldwide right to reproduce, manufacture,
     sell, license and distribute all of its products and services (such
     products and services being set forth under Item 4.14(b) of the Panopticon
     Disclosure Letter) and the right to use all of its customer and supplier
     lists. Except as set forth under Item 4.14(b), Panopticon has not granted
     any reseller, distributor, sales representative, original equipment
     manufacturer, value added reseller or other third party any right to
     reproduce, manufacture, sell, license or distribute any of its products or
     services in any market segment or geographic location. Set forth under Item
     4.14(b) is a true and complete list of all copyright, mask work and
     trademark registrations and applications and all patents and patent
     applications for Panopticon IP Rights owned by Panopticon. Panopticon is
     not aware of any loss, cancellation, termination or expiration of any such
     registration or patent except as set forth on Item 4.14(b).

                           (c) No Violation of Rights of Others. The business of
     Panopticon as conducted as of the date hereof does not, and the business of
     the licensing and use of Panopticon products and the sale of commercial
     services using such intellectual property and proprietary rights

                                      -19-

     after the Effective Time will not cause Panopticon to, infringe or violate:
     (i) with respect to any contribution or participation by any employee or
     consultant of Panopticon in developing any Panopticon product, Panopticon
     software or Panopticon IP Right, any of the Intellectual Property Rights of
     any other person; (ii) any of the Intellectual Property Rights (other than
     patent rights) of any other person; or (iii) to the knowledge of
     Panopticon, any patent rights of any other person; and Panopticon has not
     received any written or oral claim or notice of infringement or potential
     infringement of the Intellectual Property Rights of any other person which
     could be reasonably expected to have a Material Adverse Effect on
     Panopticon. To the knowledge of Panopticon, Panopticon is not using any
     confidential information or trade secrets of any past or present employees.

                           (d) Protection of Rights. Panopticon has taken
     reasonable and practicable steps designed to safeguard and maintain the
     secrecy and confidentiality of, and its proprietary rights in, all
     Panopticon IP Rights. To the knowledge of Panopticon, there is no material
     unauthorized use, infringement or misappropriation of any Panopticon IP
     Rights by any third party, including, to the knowledge of Panopticon, any
     Panopticon employee. All Panopticon officers, employees and consultants
     have executed and delivered to Panopticon an agreement regarding the
     protection of proprietary information and the assignment to Panopticon of
     all Intellectual Property Rights arising from the services performed for
     Panopticon by such persons, and Panopticon made available or has delivered
     to Broadbase copies of all such agreements. Panopticon has taken reasonable
     measures to protect all Panopticon IP Rights, and, except as set forth on
     Item 4.14(d), to the knowledge of Panopticon, Panopticon is not aware of
     any infringement of any Panopticon IP Rights by any third party.

                           (e) Conformity of Products and Services. All software
     developed by Panopticon and licensed by Panopticon to customers and all
     other products manufactured, sold, licensed, leased or delivered by
     Panopticon to customers and all services provided by Panopticon to
     customers on or prior to the Closing Date conform in all material respects
     (to the extent required in contracts with such customers) to applicable
     contractual commitments, express and implied warranties, product
     specifications and product documentation and to any representations
     provided to customers and Panopticon has no material liability (and, to
     Panopticon's knowledge, there is no legitimate basis for any present or
     future action, suit, proceeding, hearing, investigation, charge, complaint,
     claim or demand against Panopticon giving rise to any material liability
     relating to the foregoing contracts) for replacement or repair thereof or
     other damages in connection therewith in excess of any reserves therefor
     reflected on the Balance Sheet.

                  4.15 Compliance with Laws. Panopticon has complied, or prior
to the Closing Date will have complied, and is or will be at the Closing Date in
compliance, in all respects material to Panopticon, with all applicable laws,
ordinances, regulations and rules, and all orders, writs, injunctions, awards,
judgments and decrees, applicable to Panopticon or to the assets, properties and
business of Panopticon, including, without limitation:

                           (a) all applicable federal and state securities laws
     and regulations;

                           (b) all applicable federal, state and local laws,
     ordinances and regulations, and all orders, writs, injunctions, awards,
     judgments and decrees, pertaining to (i) the sale, licensing, leasing,
     ownership or management of Panopticon's owned, leased or licensed real or
     personal property, products or technical data, (ii) employment or
     employment practices, terms and conditions of employment, or wages and
     hours or (iii) safety, health, fire prevention, environmental protection

                                      -20-

     (including toxic waste disposal and related matters described in Section
     4.20), building standards, zoning or other similar matters;

                           (c) the Export Administration Act and regulations
     promulgated thereunder or other laws, regulations, rules, orders, writs,
     injunctions, judgments or decrees applicable to the export or re-export of
     controlled commodities or technical data;

                           (d) the Immigration Reform and Control Act; and

                           (e) all governmental and nongovernmental regulations
     related to the operation and use of the Internet.

                  Panopticon has received all material permits and approvals
from, and has made all material filings with, third parties, including
government agencies and authorities, that are necessary to the conduct of its
business as presently conducted.

                  4.16 Certain Transactions and Agreements. To Panopticon's
knowledge, no person who is an officer or director of Panopticon, or a member of
any officer's or director's immediate family:

                           (a) has any direct or indirect ownership interest in
     or any employment or consulting agreement with any firm or corporation that
     competes with Panopticon or Broadbase (except with respect to any interest
     in less than 1% of the outstanding voting shares of any corporation whose
     stock is publicly traded);

                           (b) is directly or indirectly interested in any
     Contract or informal arrangement with Panopticon, including, but not
     limited to, any loan arrangements, except for compensation for services as
     an officer (listed under Item 4.6 of the Panopticon Disclosure Letter),
     director or employee of Panopticon and except for the normal rights of a
     stockholder or optionholder.

                           (c) has any interest in any (i) Panopticon IP Rights
     or (ii) property (other than Panopticon IP Rights) used in the business of
     Panopticon whether such property is real or personal, tangible or
     intangible.

To Panopticon's knowledge, no Panopticon officer or director, or any "affiliate"
or "associate" (as those terms are defined in Rule 405 promulgated under the
Securities Act) of any such person has had, either directly or indirectly, a
material interest in: (i) any entity which purchases from or sells, licenses or
furnishes to Panopticon any goods, property, technology or intellectual or other
property rights or services, or (ii) any Contract to which Panopticon is a party
or by which it may be bound or affected other than with respect to arms-length
transactions.

                  4.17     Employees.

                           (a) General Compliance. Panopticon is in compliance
     in all material respects with all applicable laws and Contracts relating to
     employment, employment practices, wages, hours, and terms and conditions of
     employment, including, but not limited to, employee compensation matters,
     and has correctly classified employees as exempt employees and non-exempt
     employees under the Fair Labor Standards Act. Except as set forth under
     Item 4.17(a) of the Panopticon Disclosure Letter, Panopticon has no
     employment or consulting Contracts currently in effect that are not
     terminable at will (other than agreements with the sole purpose of
     providing for the confidentiality of proprietary information or assignment
     of inventions). All independent

                                      -21-
<PAGE>   22

     contractors have been properly classified as independent contractors for
     the purposes of federal and applicable state tax laws, laws applicable to
     employee benefits and other applicable laws. All Panopticon employees are
     legally permitted to be employed by Panopticon in the United States of
     America. Panopticon will have no liability to any employee or to any
     organization or any other entity as a result of the termination of any
     employee leasing arrangement.

                           (b) Good Labor Relations. Panopticon: (i) to
     Panopticon's knowledge has never been and is not now subject to a union
     organizing effort; (ii) is not subject to any collective bargaining
     agreement with respect to any of its employees; (iii) is not subject to any
     other Contract with any trade or labor union, employees' association or
     similar organization; and (iv) to its knowledge has no current labor
     disputes. Panopticon has good labor relations, and has no knowledge of any
     facts indicating that the consummation of the Merger or any of the other
     transactions contemplated hereby will have a Material Adverse Effect on
     such labor relations. As of the date of this Agreement, Panopticon has no
     knowledge that any key personnel or other employees intends to leave its
     employment. There are no controversies pending or, to Panopticon's
     knowledge, threatened, between Panopticon and any of its employees that
     would be reasonably likely to result in Panopticon incurring any material
     liability.

                           (c) Employee Plans. Item 4.17(c) identifies: (i) each
     "employee benefit plan", as defined in Section 3(3) of the Employee
     Retirement Income Security Act of 1974, as amended ("ERISA"); and (ii) all
     other written or formal plans or Contracts involving direct or indirect
     compensation or benefits (including any employment Contracts entered into
     between Panopticon and any employee of Panopticon, but excluding workers'
     compensation, unemployment compensation and other government-mandated
     programs) currently or previously maintained, contributed to or entered
     into by Panopticon under which Panopticon or any ERISA Affiliate (as
     defined below) has any present or future Liability (collectively, the
     "PANOPTICON EMPLOYEE PLANS"). For purposes of this Section 4.17, "ERISA
     AFFILIATE" shall mean any entity which is a member of: (i) a "controlled
     group of corporations", as defined in Section 414(b) of the Code; (ii) a
     group of entities under "common control", as defined in Section 414(c) of
     the Code; or (iii) an "affiliated service group", as defined in Section
     414(m) of the Code, or treasury regulations promulgated under Section
     414(o) of the Code, any of which includes Panopticon. Copies of all
     Panopticon Employee Plans (and, if applicable, related trust agreements)
     and all related documents, amendments and written interpretations
     (including summary plan descriptions) thereto have been delivered to
     Broadbase or its counsel, together with the two most recent annual reports
     (Form 5500, including, if applicable, Schedule B thereto) prepared in
     connection with any such Panopticon Employee Plan. No "prohibited
     transaction," as defined in Section 406 of ERISA or Section 4975 of the
     Code, has occurred with respect to any Panopticon Employee Plan which is
     covered by Title I of ERISA which would result in a material liability to
     Panopticon, excluding transactions effected pursuant to a statutory or
     administrative exemption. Nothing done or omitted to be done and no
     transaction or holding of any asset under or in connection with any
     Panopticon Employee Plan has or will make Panopticon or any Panopticon
     officer or director subject to any material liability under Title I of
     ERISA or liability for any material tax (as defined in Section 4.14) or
     penalty pursuant to Sections 4972, 4975, 4976 or 4979 of the Code or
     Section 502 of ERISA. Except as set forth in Item 4.17(c) of the Panopticon
     Disclosure Letter, no Panopticon Employee Plans will be subject to any
     surrender fees or service fees upon termination other than the normal and
     reasonable administrative fees associated with the termination of benefit
     plans. All contributions due from Panopticon with respect to any of the
     Panopticon Employee Plans have been made as required under ERISA or have
     been accrued on the Panopticon Financial Statements. Panopticon has
     performed in all material respects all obligations required to be performed
     by it under each Panopticon Employee Plan, and each

                                      -22-
<PAGE>   23

     Panopticon Employee Plan has been maintained substantially in compliance
     with its terms and with the requirements prescribed by any and all
     statutes, orders, rules and regulations, including, without limitation,
     ERISA and the Code, which are applicable to such Panopticon Employee Plans.

                           (d) Pension Plans. All Panopticon Employee Plans
     which individually or collectively would constitute an "employee pension
     benefit plan", as defined in Section 3(2) of ERISA (collectively, the
     "PANOPTICON PENSION PLANS"), are identified as such under Item 4.17(d). Any
     Panopticon Pension Plan which is intended to be qualified under Section
     401(a) of the Code (a "PANOPTICON 401(a) PLAN") is so qualified and has
     been so qualified during the period from its adoption to date, and the
     trust forming a part is exempt from tax pursuant to Section 501(a) of the
     Code. No Panopticon Pension Plan constitutes, or has since the enactment of
     ERISA constituted, a "multiemployer plan," as defined in Section 3(37) of
     ERISA. No Panopticon Pension Plans are subject to Title IV of ERISA.
     Panopticon has delivered to Broadbase or its counsel a complete and correct
     copy of the most recent Internal Revenue Service determination letter with
     respect to each Panopticon 401(a) Plan, if any exists.

                           (e) Benefit Arrangements. Item 4.17(e) lists each
     employment, severance (including all post-employment Liabilities) or other
     similar Contract or policy and each Contract providing for insurance
     coverage (including any self-insured arrangements), workers' benefits,
     vacation benefits, severance benefits, disability benefits, death benefits,
     hospitalization benefits, retirement benefits, deferred compensation,
     profit-sharing, bonuses, stock options, stock purchase, phantom stock,
     stock appreciation or other forms of incentive compensation or
     post-retirement insurance, compensation or benefits for employees,
     consultants or directors which: (i) is not an Panopticon Employee Plan;
     (ii) is entered into, maintained or contributed to by Panopticon; and (iii)
     covers any employee or former employee of Panopticon. Such Contracts and
     policies as are described in this Section 4.17(e) are herein referred to
     collectively as the "PANOPTICON BENEFIT ARRANGEMENTS." Each Panopticon
     Benefit Arrangement has been maintained in substantial compliance with its
     terms and with the requirements prescribed by any and all statutes, orders,
     rules and regulations which are applicable to such Panopticon Benefit
     Arrangement. Panopticon has delivered to Broadbase or its counsel a
     complete and correct copy or description of each Panopticon Benefit
     Arrangement. All individuals who, pursuant to the terms of any Panopticon
     Benefit Arrangement, are entitled to participate in any such Panopticon
     Benefit Arrangement, are currently participating in such Panopticon Benefit
     Arrangement or have been offered an opportunity to do so and have declined.

                           (f) Since December 31, 1999, there has been no
     amendment to, written interpretation or announcement (whether or not
     written) by Panopticon relating to, or change in employee participation or
     coverage under, any Panopticon Employee Plan or Panopticon Benefit
     Arrangement that would increase materially the expense of maintaining such
     Panopticon Employee Plan or Panopticon Benefit Arrangement in the future.

                           (g) COBRA Compliance. Panopticon has complied in all
     material respects prior to the date hereof, with the continuation coverage
     requirements of Section 4980B of the Code and the Consolidated Omnibus
     Budget Reconciliation Act of 1985, as amended ("COBRA"), Sections 601
     through 608 of ERISA, the American Civil Disabilities Act of 1990, as
     amended, and the Family Medical Leave Act of 1993, as amended, and the
     regulations thereunder, and no material tax payable on account of Section
     4980B of the Code has been incurred with respect to any current or former
     employees (or their beneficiaries) of Panopticon.

                                      -23-

                           (h) No Violation of Contracts. To the knowledge of
     Panopticon, no Panopticon employee or consultant is in violation of any
     term of any employment Contract, patent disclosure agreement,
     non-competition agreement, or any other Contract, or any restrictive
     covenant relating to the right of any such employee to be employed by
     Panopticon, or to use Intellectual Property Rights of others. To
     Panopticon's knowledge, the mere fact of employment of any Panopticon
     employee does not subject Panopticon to any liability.

                           (i) Effect of Merger.

                                    (i) Panopticon is not a party to any
         Contract or plan with any key personnel of Panopticon: (A) the benefits
         of which are contingent, or the terms of which are materially altered,
         upon the occurrence of a transaction involving Panopticon in the nature
         of any of the transactions contemplated by this Agreement; (B)
         providing any term of employment or compensation guarantee; or (C)
         providing severance benefits or other benefits after the termination of
         employment of such employee regardless of the reason for such
         termination of employment.

                                    (ii) Panopticon is not a party to any
         Contract or plan, including, without limitation, any stock option plan,
         stock appreciation rights plan or stock purchase plan, any of the
         benefits of which will be materially increased, or the vesting of
         benefits of which will be materially accelerated, by the occurrence of
         any of the transactions contemplated by this Agreement or the value of
         any of the benefits of which will be calculated on the basis of any of
         the transactions contemplated by this Agreement, except as set forth
         under Item 4.17(j).

                           (j) List of Current Panopticon Employees. A list of
     all current Panopticon employees and consultants and the current
     compensation of each is set forth under Item 4.18(k).

                  4.18 No Brokers. Except as set forth under Item 4.18 of the
Panopticon Disclosure Letter, Panopticon is not obligated for the payment of
fees or expenses of any investment banker, broker or finder in connection with
the origin, negotiation or execution of this Agreement or in connection with any
transaction provided for herein or therein.

                  4.19 Insurance. Panopticon maintains, and at all times since
its inception has maintained, fire and casualty, workers compensation, general
liability, business interruption and product liability insurance (which policies
are listed under Item 4.19 of the Panopticon Disclosure Letter) which it
believes to be reasonably prudent for similarly sized and similarly situated
businesses. Item 4.19 sets forth all material claims made under insurance
policies since December 31, 1997 and the premiums that apply with respect to
such insurance policies as of the date of this Agreement. Panopticon has not
changed insurance carriers since its inception.

                  4.20 Environmental Matters.

                           (a) For the purposes of this Agreement, the terms
     "DISPOSAL," "RELEASE," and "THREATENED RELEASE" shall have the definitions
     assigned thereto by the Comprehensive Environmental Response, Compensation
     and Liability Act of 1980, 42 U.S.C. Section 9601 et seq., as amended
     ("CERCLA"). For the purposes of this Agreement, "HAZARDOUS MATERIALS" shall
     mean any hazardous or toxic substance, material or waste which is or
     becomes prior to the Closing regulated under, or defined as a "hazardous
     substance," "pollutant," "contaminant," "toxic chemical," "hazardous
     material," "toxic substance" or "hazardous chemical" under: (i) CERCLA;

                           (b) To Panopticon's knowledge, none of Panopticon's
     properties or facilities is in violation of any federal, state or local
     law, ordinance, regulation or order relating to industrial hygiene or to
     the environmental conditions on, under or about such properties or
     facilities, including, but not limited to, soil and ground water condition.

                           (c) To Panopticon's knowledge, during the time that

         properties or facilities or transported to or from such properties or
         facilities any Hazardous Materials;

                                    (ii) there have been no disposals, releases

         transported from such premises to any site or facility now listed or
         proposed for listing on the National Priorities List, at 40 C.F.R. Part
         300, or any list with a similar scope or purpose published by any state
         authority; and

                                    (iv) there has been no litigation,
         proceeding or administrative action brought, threatened in writing
         against Panopticon, or any settlement reached by Panopticon with, any
         party or parties alleging the presence, disposal, release or threatened
         release of any Hazardous Materials on, from or under any of such
         premises.

                           (d) Panopticon has no knowledge of any presence,
     disposals, releases or threatened releases of Hazardous Materials on, from
     or under any of such properties or facilities that may have occurred prior
     to Panopticon having taken possession of any of such properties or
     facilities.

                  4.21 Year 2000 Compliance. Panopticon conducted a reasonable
review of all of the technology, systems and infrastructure used to host and
deliver its services and all material operating codes, programs, utilities and
other software, as well as all hardware and systems, utilized by it
(collectively, "SYSTEMS") to determine whether such Systems are designed to
record, store, process and present millennial dates in the same manner, and with
the same functionality, as provided on or before December 31, 1999, and on or
before June 30, 2000, and are designed to not lose functionality or degrade in
performance as a consequence of such software operating on and after December
31, 1999, and on and after June 30, 2000 (such design and performance being
referred to as "Y-2000 COMPLIANT"). All of Panopticon's systems are Y-2000
Compliant except where the failure to be Y-2000 Compliant does and will not have
a Material Adverse Effect on Panopticon or materially impair the performance of
any of Panopticon's services. Except as set forth under Item 4.21 of the
Panopticon Disclosure Letter, to the knowledge of Panopticon, all suppliers of
products or services to Panopticon are Y-2000 Compliant.

                  4.22 Warranties. Except as set forth under Item 4.22 of the
Panopticon Disclosure Letter, Panopticon has not provided to its customers (i)
any express warranties, including any warranties related to Y-2000 Compliant
issues, regarding the services it provides to such customers or (ii) rights to
obtain refunds with respect to any such services.

                  4.23 Information Supplied. None of the information supplied or
to be supplied by Panopticon for inclusion in the Notice Materials and the
Information Statement (both as defined in Section 6.5), at the date such
information is supplied and at the time of the meeting, or the date of the
written consent, of the Panopticon Shareholders to approve the Merger, contains
or will contain any untrue statement of a material fact or omits or will omit to
state any material fact required to be stated therein or necessary in order to
make the statements therein, in light of the circumstances under which they are
made, not misleading.

                  4.24 Voting Arrangements. Except for the Voting Agreements,
there are no outstanding stockholder agreements, voting trusts, proxies or other
Contracts to which Panopticon is a party or, to Panopticon's knowledge, to which
any other person or entity is a party, relating to the voting of any shares of
Panopticon's capital stock.

                  4.25 Ownership of Shares of Broadbase Capital Stock. Except as
set forth under Item 4.25 of the Panopticon Disclosure Letter, as of the date
hereof, neither Panopticon nor, to Panopticon's knowledge, any of Panopticon's
affiliates or associates (as such terms are defined under the Exchange Act of
1934): (a) beneficially owns, directly or indirectly; or (b) is party to any
Contract for the purpose of acquiring, holding, voting or disposing of, in each
case, shares of Broadbase capital stock (except for shares of Broadbase capital
stock in the aggregate representing less than 1% of the outstanding shares of
Broadbase capital stock).

                  4.26 Accuracy of Disclosure. This Agreement, its exhibits and
schedules, and any of the certificates or documents to be delivered by
Panopticon to Broadbase under this Agreement, taken together, do not contain any
untrue statement of a material fact or omit to state a material fact necessary
in order to make the statements contained herein and therein, in light of the
circumstances under which such statements were made, not misleading.

                           (b) No filing, authorization or approval,
     governmental or otherwise, is necessary to enable Broadbase or Merger Sub
     to enter into, and to perform its obligations under, this Agreement and the
     Broadbase Ancillary Agreements, except for (i) the filing of the

both) result in a termination, breach, impairment or violation of (a) any
provision of the Certificate of Incorporation or Bylaws of Broadbase or Merger
Sub, as currently in effect, (b) in any material respect, any material Broadbase
Contract, or (c) any federal, state, local or foreign judgment, writ, decree,

properties.

                  5.4 Litigation. There is no action, suit, arbitration,
mediation, proceeding, claim or, to Broadbase's knowledge, investigation
pending, nor, to Broadbase's knowledge, are any of the foregoing threatened

arbitrator that, if determined adversely to Broadbase or Merger Sub, may
reasonably be expected to have a Material Adverse Effect on Broadbase or Merger
Sub. There is no action, suit, proceeding, claim, arbitration or investigation
pending as to which Broadbase or Merger Sub has received notice of assertion
against Broadbase or Merger Sub, which in any manner challenges or seeks to
prevent, enjoin, alter or materially delay any of the transactions contemplated
by this Agreement.

written consent, of the Panopticon Shareholders to approve the Merger, contains
or will contain any untrue statement of a material fact or omits or will omit to
state any material fact required to be stated therein or necessary in order to

any customer, supplier or key employee, it will promptly bring such information
to the attention of Broadbase in writing and, if requested by Broadbase, will
exert reasonable best efforts to restore the relationship. Panopticon will use
commercially reasonable efforts to maintain its equipment and other assets in
good working condition and repair according to the standards it has maintained

                  6.5 Preparation of Permit Application, Hearing Request,

Corporate Securities Law of 1968, as amended (the "CCSL") including, but not
limited to, any required "PERMIT APPLICATION," "HEARING REQUEST," and "HEARING
NOTICE", pursuant to Sections 25121 and 25142 of the CCSL (collectively, the
"NOTICE MATERIALS"), in connection with the Merger in order to perfect the
exemption from registration provided in Section 3(a)(10) of the Securities Act.
Each of Broadbase and Panopticon shall use its reasonable best efforts to have
the Permit Application, Hearing Request and Hearing Notice declared effective
under the CCSL as promptly as practicable after such filing. In addition,
Panopticon and Broadbase will prepare and Panopticon will distribute an
information statement (the "INFORMATION STATEMENT") along with the Notice
Materials, as may be required by California Law, at the earliest practicable
date to submit this Agreement, the Merger and related matters for the
consideration and approval of the Panopticon Shareholders, which approval will
be recommended by Panopticon's Board of Directors and management. Such
Information Statement will contain information, and will be distributed, in
compliance with applicable law. Panopticon will promptly provide all information
relating to its business and operations necessary for inclusion in the Notice
Materials to satisfy all requirements of applicable state and federal securities
laws. Panopticon shall be solely responsible for any statement, information or
omission in the Notice Materials relating to it or its affiliates based upon
written information furnished by it. In the event that the Permit Application,
Hearing Request and Hearing Notice shall not have been declared effective by
September 30, 2000, then at the written request of Panopticon to Broadbase,
Broadbase and Panopticon shall take all reasonable actions necessary to qualify
the issuance of the Exchange Shares in the Merger for an exemption from
registration under the Securities Act pursuant to the Private Placement
Exemption.

                  6.6 Approval of Panopticon Shareholders.

                           (a) Panopticon will hold a special meeting or solicit
     written consent of the Panopticon Shareholders as promptly as practicable,
     and in any event (to the extent permissible under applicable law) no more
     than fifteen (15) days after the California Commissioner of Corporations
     has issued a permit declaring the Permit Application, Hearing Request and
     Hearing Notice with respect to the Merger effective, for the purpose of
     voting upon approval of this Agreement and the Merger (or if such permit
     shall not have been issued by September 30, 2000, and either Broadbase or
     Panopticon shall have delivered the written notice described in the last
     sentence


                                      -31-
<PAGE>   32



     of Section 6.5 as soon as practicable after such date). Panopticon will
     solicit from the Panopticon Shareholders proxies in favor of the approval
     of this Agreement and the Merger, and will use its reasonable best efforts
     to take all other action necessary or advisable to secure the vote or
     consent of the Panopticon Shareholders required by the rules of California
     law to obtain such approvals. Any meeting of the Panopticon Shareholders
     shall be called, held and conducted, and any proxies or shareholder written
     consents will be solicited, in compliance with California law and
     Panopticon's Articles of Incorporation and Bylaws, and all other applicable
     legal requirements. Panopticon's obligation to call, give notice of,
     convene, hold and conduct the Panopticon Shareholders Meeting or solicit a
     written consent of the Panopticon Shareholders in accordance with this
     Section 6.6 shall not be limited to or otherwise affected by the
     commencement, disclosure, announcement or submission to Panopticon of any
     Acquisition Proposal (as defined in Section 6.7), or by any withdrawal,
     amendment or modification of the recommendation of the Board of Directors
     of Panopticon to the Panopticon Shareholders to approve this Agreement and
     the Merger.

                           (b) In the event a meeting of the Panopticon
     Shareholders is held to approve this Agreement and the Merger (the
     "PANOPTICON SHAREHOLDERS MEETING"), then notwithstanding anything to the
     contrary contained in this Agreement, Panopticon may adjourn or postpone
     the Panopticon Shareholders Meeting if as of the time for which the
     Panopticon Shareholders Meeting is originally scheduled there are
     insufficient shares of Panopticon common stock represented (either in
     person or by proxy) to constitute a quorum necessary to conduct the
     business of the Panopticon Shareholders Meeting. Panopticon shall ensure
     that the Panopticon Shareholders Meeting is called, noticed, convened, held

     adverse to Broadbase, the recommendation of the Board of Directors of
     Panopticon that the Panopticon Shareholders vote in favor of and approve
     this Agreement and the Merger.

                           (d) Nothing contained in this Agreement shall

     the Panopticon Shareholders a position contemplated by Rules 14d-9 and
     14e-2(a) promulgated under the Exchange Act of 1934.

                           (c) In addition to the obligations of Panopticon set
     forth in Section 6.7(b), Panopticon as promptly as practicable shall advise
     Broadbase orally and in writing of any request for non-public information
     or any other inquiry which Panopticon reasonably believes could lead to an
     Acquisition Proposal or of any Acquisition Proposal, the material terms and
     conditions of such request, inquiry or Acquisition Proposal, and the
     identity of the person or group making any such request, inquiry or
     Acquisition Proposal. Panopticon will keep Broadbase informed as promptly
     as practicable in all material respects of amendments to any such request,
     inquiry or Acquisition Proposal.

                  6.8 Regulatory Approvals. Panopticon will execute and file, or

                                      -33-
<PAGE>   34

                  6.9 Necessary Consents. Panopticon will use reasonable best
efforts to obtain such written consents and take such other actions as may be
necessary or appropriate for Panopticon, in addition to those set forth in
Section 6.5, to allow the consummation of the transactions provided for herein
and to facilitate and allow Broadbase to carry on Panopticon's business after
the Closing Date. Panopticon will use its best efforts to obtain from Kindling
LLC waivers of any acceleration provisions that would be triggered by the
Merger.

                  6.10 Blue Sky Laws. Panopticon shall use reasonable efforts to
assist Broadbase to the extent necessary to comply with the securities and Blue
Sky laws of all jurisdictions applicable in connection with the Merger.

                  6.11 Panopticon Dissenting Shares. As promptly as practicable
after the date the Information Statement is distributed to Panopticon
Shareholders and prior to the Closing Date, Panopticon shall furnish Broadbase
with the name and address of each Panopticon Shareholder who has up to such time
dissented and the number of shares owned by such Panopticon Shareholders.

                  6.12 Litigation. Panopticon will notify Broadbase in writing
promptly after learning of any material action, suit, proceeding or
investigation by or before any court, board or governmental agency, initiated by
or against Panopticon or threatened against it. If Panopticon becomes subject to
a review by the Internal Revenue Service or any other taxing agency or authority
for accounting periods prior to the Closing Date (including but not limited to
any short tax year resulting from the Merger), then Panopticon acknowledges that
Broadbase will be entitled to participate in such review and that Panopticon
shall be responsible for payment of any assessment subject to the limitations on
indemnification contained in Article 12. Panopticon will not enter into any
settlement or other stipulation with respect to any such review without the
written consent of Broadbase, which consent will not be unreasonably withheld.

                  6.13 Certain Employee Benefits. As soon as practicable after
the execution of this Agreement, Panopticon and Broadbase shall confer and work
together in good faith to agree upon mutually acceptable employee benefit and
compensation arrangements for Panopticon employees following the Merger.
Panopticon shall take such actions as are necessary to terminate such Panopticon
Employee Plans as are requested by Broadbase to be terminated, provided that
those Panopticon employees who are eligible to participate in each such Employee
Plan shall be provided the opportunity to participate in a substantially
comparable employee benefit plan maintained by Broadbase and provided further
that Broadbase requests such termination no later than ten days prior to the
Closing Date. Panopticon agrees that it shall terminate any and all group
severance, separation, retention and salary continuation plans, programs or
arrangements (other than agreements entered into by certain individuals to
effect transactions contemplated by this Agreement) prior to the Closing.

                  6.14 Notification of Employee Problems. Panopticon will
promptly notify Broadbase if any of Panopticon's officers becomes aware that any
of the key employees listed under Item 4.6 of the Panopticon Disclosure Letter
intends to leave its employ.

                  6.15 Certain Agreements. Panopticon will use all reasonable
efforts to cause all present employees and consultants of Panopticon who have
not previously executed Panopticon's forms of assignments of copyright and other
intellectual property rights to Panopticon to execute such forms, copies of
which are attached hereto as Exhibit F.

                                      -34-
<PAGE>   35

                  6.16 Panopticon Affiliates. To help ensure that the issuance
of the Exchange Shares complies with the Securities Act, prior to the Closing
Date Panopticon will deliver a letter identifying all persons who are, in
Panopticon's reasonable judgment, "affiliates" of Panopticon at that time (the
"PANOPTICON AFFILIATES"). Panopticon will provide Broadbase with all information
and documents needed to evaluate this list for compliance with securities laws.
Broadbase will cause the Exchange Shares issued to the Panopticon Affiliates to
bear legends with respect to any application limitations on transfer under Rule
145 promulgated under the Securities Act.

                  6.17 Tax Free Reorganization. Panopticon will cooperate with
the other parties and take all reasonable actions as may be necessary to ensure
that this Agreement involves a tax-free plan of reorganization and that the
Merger is consummated in accordance with the provisions of Section 368(a)(1)(A)
and Section 368(a)(2)(E) of the Code.

                  6.18 Satisfaction of Closing Conditions. Panopticon will use
its reasonable best efforts to satisfy or cause to be satisfied all the
conditions precedent which are set forth in Article 10 on or before September
15, 2000, subject to any regulatory approvals or requirements. Panopticon will
use its reasonable best efforts to cause the transactions contemplated by this
Agreement to be consummated, and, without limiting the generality of the
foregoing, to obtain all consents and authorizations of third parties and to
make all filings with, and give all notices to, third parties that may be
necessary or reasonably required on its part in order to effect the transactions
contemplated hereby.


         7.       BROADBASE PRE-CLOSING COVENANTS

                  During the period from the date of this Agreement until the
Effective Time, Broadbase covenants to and agrees with Panopticon as follows:

                  7.1 Advice of Changes. Broadbase will promptly advise
Panopticon in writing of: (i) the discovery by Broadbase of any event,
condition, fact or circumstance occurring on or prior to the date of this
Agreement that would render any representation or warranty by Broadbase
contained in this Agreement untrue or inaccurate in any material respect; (ii)
any event, condition, fact or circumstance occurring subsequent to the date of
this Agreement that would render any representation or warranty by Broadbase
contained in this Agreement, if made on or as of the date of such event or the
Closing Date, untrue or inaccurate in any material respect; (iii) any breach of
any covenant or obligation of Broadbase pursuant to this Agreement or any
Ancillary Agreement; (iv) any event, condition, fact or circumstance that may
make the timely satisfaction of any of the conditions set forth in Article 9
impossible or unlikely; and (v) any Material Adverse Effect on Broadbase.

                  7.2 Regulatory Approvals. Broadbase will execute and file, or
join in the execution and filing, of any application or other document that may
be necessary in order to obtain the authorization, approval or consent of any
governmental body, federal, state, local or foreign, which may be reasonably
required, or which Panopticon may reasonably request, in connection with the
consummation of the transactions provided for in this Agreement. Broadbase will
use reasonable best efforts to obtain all such authorizations, approvals and
consents.

                  7.3 Preparation of Permit Application, Hearing Request and
Hearing Notice. As promptly as practicable after the date hereof, Broadbase,
with Panopticon's assistance, shall prepare and file with the California
Commissioner of Corporations the Notice Materials, including the Permit
Application, Hearing Request and Hearing Notice, in connection with the Merger.
Broadbase, with

                                      -35-
<PAGE>   36

Panopticon's assistance, shall use its reasonable best efforts to have the
Permit Application, Hearing Request and Hearing Notice declared effective under
the CCSL as promptly as practicable after such filing. Broadbase will promptly
provide all information relating to its business and operations necessary for
inclusion in the Notice Materials to satisfy all requirements of applicable
state and federal securities laws. Broadbase shall be solely responsible for any
statement, information or omission in the Notice Materials relating to it or its
affiliates based upon written information furnished by it. In the event that the
Permit Application, Hearing Request and Hearing Notice shall not have been
declared effective by September 30, 2000, then at the written request of
Panopticon to Broadbase, Broadbase and Panopticon shall take all reasonable
actions necessary to qualify the issuance of the Exchange Shares in the Merger
for an exemption from registration under the Securities Act pursuant to the
Private Placement Exemption.

                  7.4 Litigation. Broadbase will notify Panopticon in writing
promptly after learning of any litigation or proceeding threatened or pending
for the purpose or with the probable effect of enjoining or preventing the
consummation of any of the transactions contemplated by this Agreement, or which
would be reasonably expected to have a Material Adverse Effect on Broadbase.

                  7.5 Certain Employee Benefits. After the Effective Time,
Broadbase shall grant (or cause to be granted) to each Panopticon employee
credit for all service with Panopticon prior to the Effective Time to the same
extent as if such service had been with Broadbase for (a) all eligibility and
vesting purposes under all employee benefit plans, policies, programs and
arrangements of Broadbase and any of its subsidiaries that cover an Panopticon
employee, (b) vacation accrual purposes after the Effective Time, and (c)
purposes of satisfying any preexisting condition exclusion or actively-at-work
requirement that would otherwise apply to each Panopticon employee under any
medical, dental or other welfare benefit plans, policies, programs and
arrangements of Broadbase and any of its subsidiaries that employ a Panopticon
employee, to the extent that this clause (c) does not violate the applicable
plan, policy, program or arrangement.

                  7.6 Tax Free Reorganization. Broadbase will cooperate with the
other parties and take all reasonable actions as may be necessary to ensure that
this Agreement involves a tax-free plan of reorganization and that the Merger is
consummated in accordance with the provisions of Section 368(a)(1)(A) and
Section 368(a)(2)(E) of the Code.

                  7.7 Satisfaction of Conditions Precedent. Broadbase will use
its reasonable best efforts to satisfy or cause to be satisfied all the
conditions precedent which are set forth in Article 9 on or before September 15,
2000, subject to any regulatory approvals or requirements. Broadbase will use
reasonable best efforts to cause the transactions provided for in this Agreement
to be consummated, and, without limiting the generality of the foregoing, to
obtain all consents and authorizations of third parties and to make all filings
with, and give all notices to, third parties that may be necessary or reasonably
required on its part in order to effect the transactions provided for herein.

                  7.8 Indemnification of Directors and Officers; Directors &
Officers Insurance.

                           (a) From and after the Effective Time, Broadbase will
     cause the Surviving Corporation to fulfill and honor in all respects the
     obligations of Panopticon pursuant to any indemnification agreements
     between Panopticon and its directors and officers as of or prior to the
     date hereof (or indemnification agreements in Panopticon's customary form
     for directors joining Panopticon's Board of Directors prior to the
     Effective Time) and any indemnification provisions


                                      -36-
<PAGE>   37

     under Panopticon's Articles of Incorporation or bylaws as in effect
     immediately prior to the Effective Time.

                           (b) For a period of three years after the Effective
     Time, Broadbase will maintain or cause the Surviving Corporation to
     maintain in effect, if available, directors' and officers' liability
     insurance covering those persons who, as of immediately prior to the
     Effective Time, were scheduled to be covered by Panopticon's directors' and
     officers' liability insurance policy (the "INSURED PARTIES").

                           (c) The provisions of this Section 7.7 are intended
     to be for the benefit of, and will be enforceable by, each Insured Party
     entitled to indemnification hereunder and the heirs and representatives of
     such Insured Party. Broadbase will not permit the Surviving Corporation to
     merge or consolidate with any other entity unless the Surviving Corporation
     will ensure that the surviving or resulting entity assumes the obligations
     imposed by this Section 7.7.

                  7.9 Interim Financing.

                           (a) Provided this Agreement has not been terminated
     as provided in Article 11, Broadbase agrees to lend up to an aggregate of
     $2,000,000 to Panopticon (the "LOAN") for the purpose of financing
     operating expenses incurred in the ordinary course of business, pursuant to
     the terms set forth in the form of convertible promissory note attached
     hereto as Exhibit G, and subject to execution and delivery of such note by
     Panopticon. Each advance of all or any portion of the Loan shall be subject
     to the conditions that (i) the representations and warranties of Panopticon
     set forth in this Agreement shall be true and correct as of the time of
     such advance (provided that this condition shall be deemed satisfied unless
     the cumulative effect of such inaccuracies and breaches has a Material
     Adverse Effect on Panopticon), (ii) Panopticon shall not have breached any
     material covenant contained in this Agreement, and (iii) Panopticon shall
     have given Broadbase at least five (5) days' written notice requesting such
     advance and affirming that the conditions described in clauses (i) and (ii)
     have been satisfied.

                           (b) If this Agreement is terminated by Broadbase
     pursuant to Section 11.1(b) or the provisions specifically enumerated in
     Section 11.4, then all unpaid principal and accrued interest under the Loan
     shall be accelerated and shall become due and payable by Panopticon upon
     the earliest to occur of: (i) Panopticon's next equity financing of at
     least $5 million, (ii) an Acquisition of Panopticon, or (iii) the date that
     is six months after the date of such termination. Panopticon may pre-pay
     any unpaid principal and accrued interest under the Loan upon two days'
     written notice to Broadbase. At the election of Broadbase, the Loan may
     instead be converted into shares of Panopticon preferred stock issued in
     Panopticon's next equity financing at a conversion price equal to the price
     per share of the equity securities sold in such equity financing, and each
     party hereto will take all steps necessary or advisable to effect such
     result.

         8.       CLOSING MATTERS

                  8.1 The Closing. Subject to termination of this Agreement as
provided in Article 11, the closing of the transactions provided for herein (the
"CLOSING") will take place at the offices of Fenwick & West LLP, Two Palo Alto
Square, Palo Alto, California 94306 at 10:00 a.m., Pacific Time no later than
the later of September 15, 2000 and the third business day after all conditions
to closing have been satisfied or waived (the "CLOSING DATE"). Prior to or
concurrently with the Closing, the Agreement of Merger, Certificate of Merger
and such officers' certificates or other documents as may be required to

                                      -37-
<PAGE>   38

effectuate the Merger will be filed in the offices of the California Secretary
of State and Delaware Secretary of State, respectively.

                  8.2 Exchange of Certificates.

                           (a) Procedures.

                                    (i) U.S. Stock Corporation, transfer agent
         for Broadbase common stock, will act as exchange agent (the "EXCHANGE
         AGENT") for the Exchange Shares. On the Closing Date, Broadbase will
         deposit with the Exchange Agent the Exchange Shares, to be held by the
         Exchange Agent until released as provided herein. Within a reasonable
         time after the Closing, Broadbase shall cause to be mailed to each
         holder of record of a certificate(s) for shares of Panopticon capital
         stock (the "PANOPTICON CERTIFICATES"): (A) a letter of transmittal
         (which shall specify that delivery shall be effected, and risk of loss
         and title to the Panopticon Certificates shall pass, only upon delivery
         of the Panopticon Certificates to the Exchange Agent), and (B)
         instructions for use in effecting the surrender of the Panopticon
         Certificates in exchange for certificates representing Exchange Shares.
         As soon as practicable after the Effective Time, each Panopticon
         Shareholder (1) will surrender either (x) the Panopticon Certificates
         to Broadbase for cancellation or (y) an affidavit of lost certificate
         (or nonissued) and a bond in form and amount reasonably satisfactory to
         Broadbase or the Exchange Agent (a "BOND"), (2) will execute and
         deliver an indemnification letter pursuant to which each Panopticon
         Shareholder will agree to indemnify the Indemnified Persons (as defined
         in Section 12.2) pursuant to the terms of Article 12 (the
         "INDEMNIFICATION LETTER"), (3) will execute and deliver representations
         as to such Panopticon Shareholder's valid and marketable title to such
         holder's shares of Panopticon common stock, and (4), if a permit is not
         obtained from the California Department of Corporations as contemplated
         by Section 6.5, a representation letter stating that such shareholder
         is acquiring the "Exchange Shares" for investment purposes and not with
         a view to any distribution thereof, and such other matters as Broadbase
         may reasonably require in order to establish the Private Placement
         Exemption (items 3 and 4 collectively, the "PANOPTICON SHAREHOLDER
         REPRESENTATIONS"). Promptly following the Effective Time and receipt of
         Panopticon Certificates and/or the Bonds, the Indemnification Letter
         and the Panopticon Shareholder Representations, Broadbase will cause
         the Exchange Agent to issue to such surrendering holder certificate(s)
         for the number of Exchange Shares to which such holder is entitled
         pursuant to Section 2.1, less the Escrow Shares to be deposited into
         escrow on behalf of such holder pursuant to Section 2.2, and will
         distribute any cash payable under Section 2.1(a)(v).

                                    (ii) At the Effective Time, the stock
         transfer books of Panopticon will be closed and no transfer of shares
         of Panopticon capital stock will thereafter be made. If, after the
         Effective Time, Panopticon Certificates are presented for any reason,
         they will be canceled and exchanged as provided in this Section 8.2;
         provided, however, that subject to applicable law any Panopticon
         Certificate that is not properly submitted to Broadbase for exchange
         and cancellation within three years after the Effective Time shall no
         longer evidence ownership of or any right to receive shares of
         Broadbase common stock and all rights of the holder of such Panopticon
         Certificate, with respect to the shares previously evidenced by such
         Panopticon Certificate, shall cease.

                                    (iii) Subject to the provisions of Section
         2.2 and the Escrow Agreement with respect to the Escrow Shares, all
         Exchange Shares delivered upon the surrender of Panopticon Certificates
         in accordance with the terms hereof will be deemed to have been

                                      -38-
<PAGE>   39

         delivered in full satisfaction of all rights pertaining to the
         Panopticon common stock evidenced by such Panopticon Certificates.

                           (b) Unexchanged Shares. Until Panopticon Certificates
     outstanding prior to the Merger (or affidavits of lost (or non-issued)
     certificates and attendant Bonds) are surrendered pursuant to Section
     8.2(a), such Panopticon Certificates will be deemed, for all purposes, to
     evidence ownership of (i) the number of Exchange Shares into which the
     Panopticon common stock will have been converted (less the number of shares
     to be withheld as Escrow Shares pursuant to Section 2.2) and (ii) if
     applicable, cash in lieu of fractional shares.

                           (c) Payment of Dividends. No dividends or
     distributions payable to holders of record of Broadbase common stock after
     the Effective Time, or cash payable in lieu of fractional shares, will be
     paid to holders of any unsurrendered Panopticon Certificates until such
     holders surrender their Panopticon Certificates (or affidavits of lost (or
     non-issued) certificates and attendant Bonds). Upon such surrender, subject
     to the effect, if any, of applicable escheat and other laws, there will be
     delivered to such tendering holder the amount of any dividends and
     distributions paid with respect to Exchange Shares so withheld as of any
     date subsequent to the Effective Time and prior to such date of delivery,
     less any stock dividends for Escrow Shares that are issued in order to
     effect a stock split of Broadbase common stock (which shall be held until
     the Escrow Shares are released). Except for the Escrow Shares, no other
     interest shall be paid on any such dividends withheld.

                           (d) Miscellaneous.

                                    (i) If any certificates for Exchange Shares
         are to be issued in a name other than that in which the Panopticon
         Certificate surrendered in exchange therefor is registered, the
         following shall be conditions of such exchange: (A) the Panopticon
         Certificate must be properly endorsed and otherwise in proper form for
         transfer, and (B) the person requesting such exchange shall either pay
         to the Exchange Agent any transfer or other taxes required by reason of
         the issuance of certificates for such Exchange Shares in a name other
         than that of the registered holder of the Panopticon Certificate
         surrendered or establish to the satisfaction of the Exchange Agent that
         such tax has been paid or is not applicable.

                                    (ii) Notwithstanding anything in this
         Agreement to the contrary, neither the Exchange Agent nor any party
         hereto shall be liable to a Panopticon Shareholder for any Exchange
         Shares or dividends thereon or the cash payments otherwise due
         hereunder delivered to a public official pursuant to applicable
         abandoned property, escheat or other similar laws following the passage
         of time specified therein.

                  8.3 Dissenting Shares. Notwithstanding anything to the
contrary in this Agreement:

                           (a) For each Panopticon Shareholder who exercises
     appraisal rights with respect to shares of Panopticon capital stock in
     accordance with Chapter 13 of the California General Corporation Law
     ("CALIFORNIA CODE") and, as of the Effective Time, has not lost or
     effectively withdrawn such appraisal rights, such Panopticon shares
     ("DISSENTING SHARES") will not be converted into or represent a right to
     receive the consideration described in Section 2.1(a)(i). Instead, each
     holder of Dissenting Shares will be entitled only to such rights as are
     granted by Chapter 13 of the California Code. The Exchange Shares to which
     such dissenting Panopticon Shareholders would have been entitled had each
     assented to the merger will have the status of authorized and unissued
     shares of Broadbase.

                                      -39-
<PAGE>   40

                           (b) For each Panopticon Shareholder who demands
     appraisal rights with respect to such shares, but subsequently loses
     (through the failure to perfect or otherwise) or effectively withdraws such
     demand for appraisal rights in accordance with Chapter 13 of the California
     Code, such holder's shares shall, as of the Effective Time (or, if after
     the Effective Time, upon the occurrence of such event) automatically be
     converted into and represent only the right to receive the consideration
     described in Section 2.1 upon surrender of the applicable certificate(s) as
     provided in Section 8.2.

                           (c) Panopticon shall comply with the notice and other
     procedural requirements set forth in Chapter 13 of the California Code with
     respect to any Panopticon Shareholder who demands appraisal rights for such
     Panopticon shares and has not lost or effectively withdrawn such demand for
     appraisal rights. Broadbase shall have the opportunity to participate in
     all negotiations and proceedings with respect to such demands. Panopticon
     shall not, except with the prior written consent of Broadbase, voluntarily
     make any payment with respect to any demands for the exercise of appraisal
     rights or offer to settle or settle any such demands.

                  8.4 Employee Plans. As of the Effective Time, Broadbase and
Panopticon shall take such actions as are necessary to effect the mutually
acceptable employee benefit and compensation arrangements as determined pursuant
to Section 6.13.

(a) changes in general economic conditions, (b) changes affecting the industry
generally in which Panopticon operates which do not affect Panopticon
disproportionately, or (c) any omission of Panopticon directly resulting from
Broadbase's failure to consent to actions requested to be taken by Panopticon

Kim, or (ii) Craig Hughes, or (iii) any two or more of Arash Afrakhteh, Alan

         11.      TERMINATION OF AGREEMENT

                  11.1 Right to Terminate. This Agreement may be terminated and
the Merger abandoned at any time prior to the Effective Time, whether before or
after approval by the Panopticon Shareholders:

                           (a) by the mutual written consent of Panopticon and
     Broadbase;

                           (b) by either Panopticon or Broadbase, if such party
     (including its stockholders) is not in material breach of any
     representation, warranty, covenant or agreement contained in this
     Agreement, and such other party is in material breach of any
     representation, warranty, covenant or agreement contained in this
     Agreement, or if any representation of such other party will have become
     untrue, in either case to an extent that would cause the conditions set
     forth in Article 9 (for Panopticon) or Article 10 (for Broadbase) not to be
     satisfied and such breaching party fails to cure such material breach
     within fifteen (15) days of written notice of such material breach from the
     non-breaching party (except that no cure period will be provided for a
     breach which by its nature cannot be cured);

                           (c) by either Panopticon or Broadbase, if any of the
     conditions precedent to such party's obligations set forth in Article 9
     (for Panopticon) or Article 10 (for Broadbase) have not

                                      -43-
<PAGE>   44

     been fulfilled or waived on or before November 15, 2000 (the "FINAL DATE")
     other than as a result of a breach of this Agreement by the terminating
     party;

                           (d) by either Panopticon or Broadbase, if there is a
     final nonappealable order of a federal or state court in effect preventing
     consummation of the Merger, or if any statute, rule, regulation or order is
     enacted, promulgated or issued or deemed applicable to the Merger by any
     governmental body that would make consummation of the Merger illegal; or

                           (e) by either Panopticon or Broadbase if the required
     approval of the Panopticon Shareholders contemplated by this Agreement
     shall not have been obtained by reason of the failure to obtain the
     required vote by written consent or at a meeting of the Panopticon
     Shareholders duly convened therefore or at any adjournment thereof;
     provided, however, that the right to terminate this Agreement under this
     11.1 shall not be available to a party where the failure to obtain the
     Panopticon Shareholder approval shall have been caused by the action or
     failure to act of such party (or an officer or director of such party) and
     such action or failure to act constitutes a material breach of this
     Agreement.

                  11.2 Termination Procedures. If either party wishes to
terminate this Agreement pursuant to Section 11.1, such party shall deliver to
the other party a written notice stating that such party is terminating this
Agreement and setting forth a brief description of the basis of such
termination. Termination of this Agreement will be effective upon the delivery
of such notice.

                  11.3 Continuing Obligations. In the event of the termination
of this Agreement as provided in Section 11.1, this Agreement shall be of no
further force or effect, except (i) as set forth in this Section 11.3 and
Article 12, each of which shall survive the termination of this Agreement, and
(ii) nothing herein shall relieve any party from liability for any willful
breach of this Agreement. No termination of this Agreement shall affect the
obligations of the parties pursuant to any agreement to maintain the
confidentiality of information regarding the other party, all of which
obligations shall survive termination of this Agreement in accordance with their
terms.

                  11.4 Termination Fee. In the event that this Agreement is
terminated by Broadbase for any reason other than: (i) those reasons enumerated
in Section 11.1 (a), (d), or (e); (ii) pursuant to Section 10.1 (but only with
respect to any Material Adverse Effect on Panopticon arising, as a result of
inaccuracies of representations or breaches of warranties made as of the date of
this Agreement); (iii) pursuant to Section 10.2; and (iv) pursuant to Section
10.3, with respect to any Material Adverse Effect on Panopticon arising out of
matters covered by (A) Section 4.8 (with respect to the Panopticon IP Rights
only) and Section 4.14, and (B) if either (1) Stanley Kim, or (2) Craig Hughes,
or (3) any two or more of Arash Afrakhteh, Alan Thornton Gous, Miguel Lobo, and
Arman Magbouleh, or (4) 25% or more of the employees employed by Panopticon as
of the date of this Agreement, is (are) not an employee(s) (or, in the case of
Mr. Gous, a consultant) of Panopticon as of the Effective Time, then:

                           (a) Broadbase shall promptly, but in no event later
     than five days after the date of such termination, pay Panopticon in
     immediately available funds a fee equal to $8 million (the "TERMINATION
     FEE"), plus an amount equal to Panopticon's reasonable investment banking,
     accounting and attorneys' fees and expenses and other fees and expenses
     incurred by Panopticon with respect to this Agreement and the transactions
     contemplated hereby (except that the amount of such expenses to be paid by
     Broadbase shall not be in excess of the amount set forth in Section 3.2)
     provided that

                                      -44-
<PAGE>   45

                           (b) if any principal or interest under any of the
     Loan contemplated by Section 7.8 remain outstanding, then the Termination
     Fee payable by Broadbase pursuant to this Section 11.2(b) shall be reduced
     by the amount of the Loan owed by Panopticon.

The payment provided for in this Section 11.4 shall be treated as liquidated
damages and shall be in lieu of any other payments for damages incurred by
Panopticon or its shareholders for any termination of this Agreement by
Broadbase pursuant to this Section 11.4.


         12.      SURVIVAL OF REPRESENTATIONS, INDEMNIFICATION AND
                  REMEDIES, CONTINUING COVENANTS

                  12.1 Survival of Representations. All representations,
warranties, covenants and agreements of Broadbase and Panopticon contained in
this Agreement will remain operative and in full force and effect, regardless of
any investigation made by or on behalf of the parties to this Agreement, until
the earlier of the termination of this Agreement and the expiration of the
Escrow Period, whereupon such representations, warranties, covenants and
agreements will expire.

                  12.2 Agreement to Indemnify. Subject to the limitations set
forth in this Article 12, Panopticon and each of the Panopticon Shareholders
hereby agree (and each Panopticon Shareholder shall execute and deliver to
Broadbase an Indemnification Letter to signify such agreement) to severally
indemnify and hold harmless Broadbase and its officers, directors, agents and
employees, and each person, if any, who controls or may control Broadbase within
the meaning of the Securities Act (hereinafter referred to individually as an
"INDEMNIFIED PERSON" and collectively as "INDEMNIFIED PERSONS") from and against
any and all claims, demands, actions, causes of actions, losses, costs, damages,
liabilities and expenses, including without limitation, reasonable legal fees
and costs (hereinafter referred to as "DAMAGES") directly or indirectly arising
out of or resulting from:

                           (a) any misrepresentation or breach of or default in
     connection with any of the representations, warranties, agreements and
     covenants given or made by Panopticon in this Agreement or any certificate,
     document or instrument delivered by or on behalf of Panopticon pursuant
     hereto, including, without limitation, any Damages arising out of or
     relating to the Non-Exercisable Panopticon Warrants; or

                           (b) any failure of such Panopticon Shareholders (i)
     to have good, valid and marketable title to the issued and outstanding
     Panopticon common stock held by such shareholders, free and clear of all
     liens, claims, pledges, options, adverse claims, assessments or charges of
     any nature whatsoever, or (ii) to have full right, capacity and authority
     to vote such Panopticon common stock in favor of the Merger and the other
     transactions contemplated hereby;

provided, however, that for purposes of the foregoing clause (b), the
Indemnified Person may only seek and recover Damages from the Indemnifying
Stockholder who failed to have good, valid and marketable title to or authority
to vote the issued and outstanding Panopticon common stock held by such
Indemnifying Stockholder.

                  12.3 Limitations on Liability; Exceptions.

                           (a) Limitations on Liability. Except as set forth in
     Section 12.3(b), the Escrow Shares and any other assets deposited in escrow
     pursuant to the Escrow Agreement shall be the Indemnified Persons' sole
     recourse under this Agreement, and no claim for Damages shall first

                                      -45-
<PAGE>   46


     be made under Section 12.2 or otherwise under this Agreement after
     expiration of the Escrow Period. Except as set forth in Section 12.3(b),
     the remedies set forth in this Article 12 shall be the exclusive remedies
     of Broadbase and the other Indemnified Persons against any Panopticon
     Shareholder under any theory or liability.

                           (b) Exceptions to Limitations on Liability. None of
     the limitations set forth in Section 12.3(a) shall in any manner limit the
     liability or indemnification obligations of the Panopticon Shareholders
     with respect to: (i) intentional fraud or willful misconduct, (ii) any
     breach of the representations and warranties made in Section 4.5 or any
     claim for Damages arising out of or relating to the Non-Exercisable
     Panopticon Warrants, or (iii) any matter or claim described in Section
     12.2(b), except that the liability or indemnification obligation of each
     individual Panopticon Shareholder with respect to items within (ii) or
     (iii) above shall be limited to the consideration received or to be
     received by such Panopticon Shareholder in connection with the Merger.

                           (c) Basket. Except for indemnification with respect
     to fees and expenses pursuant to Section 3.2, the indemnification provided
     for in this Article 12 shall not apply unless the aggregate Damages, as the
     case may be, for which one or more Indemnified Persons seeks
     indemnification exceeds $100,000, in which event the indemnification
     provided for in this Article 12 will include the aggregate of all Damages.

                  12.4 Survival of Claims. Notwithstanding anything to the
contrary, if, prior to the expiration of the Escrow Period, an Indemnified
Person makes a claim for indemnification under either this Agreement or the
Escrow Agreement with respect to a misrepresentation or breach of such
representation, warranty or covenant, then the Indemnified Person's rights to
indemnification under this Article 12 for such claim shall survive the
expiration of the Escrow Period.

                  12.5 No Indemnity for Corporate Agents. Each of the
indemnifying shareholders agrees that such indemnifying shareholder will not
make any claim for indemnification against Panopticon by reason of the fact that
such indemnifying shareholder was a director, officer, employee or agent of any
such entity or was serving at the request of any such entity as a partner,
trustee, director, officer, employee or agent of another entity (whether such
claims is for judgments, damages, penalties, fines, costs, amounts paid in
settlement, losses, expense or otherwise and whether such claim is pursuant to
any statute, charter document, bylaw, agreement or otherwise) with respect to
any action, suit, proceeding, complaint, claim or demand brought by Broadbase
against the indemnifying shareholder (whether such action, suit, proceeding,
complaint, claim or demand is pursuant to this Agreement, applicable law or
otherwise).

                  12.6 Panopticon Shareholders' Representative.

                           (a) Authority. The Panopticon Shareholders, by their
     approval of the Merger and/or their tender pursuant to Section 8.2 of
     Panopticon Certificates, will be conclusively deemed to have consented to,
     approved and agreed to be personally bound by: (a) the indemnification
     provisions of Article 12, (b) the Escrow Agreement, (c) the appointment of
     Stanley Kim as the representative of the Panopticon Shareholders (the
     "REPRESENTATIVE") under the Escrow Agreement and as the attorney-in-fact
     and agent for and on behalf of the Panopticon Shareholders (including their
     successors and assigns) as provided in the Escrow Agreement and (d) the
     taking by the Representative of any and all actions and the making of any
     decisions required or permitted to be taken by the Representative under the
     Escrow Agreement, including, without limitation, the exercise of the power
     to: (i) authorize delivery to Broadbase of Escrow Shares in satisfaction of
     indemnity


                                      -46-
<PAGE>   47

     claims by Broadbase or any other Indemnified Person (as defined herein)
     pursuant to Article 12 hereof and/or the Escrow Agreement; (ii) agree to,
     negotiate, enter into settlements and compromises of, demand arbitration
     of, and comply with orders of courts and awards of arbitrators with respect
     to, such claims; (iii) arbitrate, resolve, settle or compromise any claim
     for indemnity made pursuant to Article 12; (iv) waive any right of any or
     all of the Panopticon Shareholders following the Merger with respect to
     matters set forth in this Agreement, the Escrow Agreement or any other
     agreement contemplated by this Agreement; (v) give and receive all notices
     required to be given under this Agreement and the Escrow Agreement; and
     (vi) take all actions necessary in the sole judgment of the Representative
     for the accomplishment of the foregoing. The Representative will have
     unlimited authority and power to act on behalf of the Panopticon
     Shareholders with respect to the Escrow Agreement and the disposition,
     settlement or other handling of all claims governed by the Escrow
     Agreement, and all rights or obligations arising under the Escrow Agreement
     so long as all Panopticon Shareholders are treated in the same manner. The
     Representative is authorized to take any actions deemed by him to be
     appropriate or reasonably necessary to carry out the provisions of Article
     12 hereof. In addition, the Representative is authorized to accept service
     of process upon the Panopticon Shareholders. All decisions and actions of
     the Representative in connection with this Agreement and the Escrow
     Agreement shall be binding and conclusive upon the Panopticon Shareholders,
     and Broadbase, the Surviving Corporation and the Escrow Agent will be
     entitled to rely on any action or decision of the Representative. The
     Representative will not be a trustee for any Panopticon Shareholder or have
     any fiduciary duty to any Panopticon Shareholder, and in performing the
     functions specified in this Agreement and the Escrow Agreement, the
     Representative will not be liable to any Panopticon Shareholders for any
     act or omission the Representative made in good faith and in the exercise
     of reasonable judgment. As provided in the Escrow Agreement, any
     out-of-pocket costs and expenses reasonably incurred by the Representative
     in connection with actions taken pursuant to the terms of the Escrow
     Agreement, at the Representative's option, either (i) will be paid by the
     Panopticon Shareholders to the Representative or (ii) if shares are
     available for distribution to the Panopticon Shareholders pursuant to the
     Escrow Agreement, at the request of the Representative, a portion of those
     shares will be sold by the Escrow Agent and the proceeds paid to or at the
     direction of the Representative, in either case, pro rata in proportion to
     the Panopticon Shareholders' respective percentage interests in the Escrow
     Shares.

                           (b) Standard of Conduct. Neither the Representative
     nor any of his partners, members, directors, officers, employees or agents
     shall be liable to any of the Panopticon Shareholders for any error of
     judgment, act done or omitted by them, or mistake of fact or law in
     connection with his services pursuant to Article 12, unless caused by his
     own gross negligence or willful misconduct. In taking any action or
     refraining from taking any action whatsoever the Representative shall be
     protected in relying upon any notice, paper or other document reasonably
     believed by him to be genuine, or upon any evidence reasonably deemed by
     him to be sufficient. The Representative shall not be required to take any
     action which is contrary to this Agreement, the Escrow Agreement or
     applicable law. The Representative may consult with counsel in connection
     with his duties and shall be fully protected in any act taken, suffered or
     permitted by them in good faith in accordance with the advice of counsel.
     In connection with their services under Article 12, the Representative
     shall not be responsible for determining or verifying the authority of any
     person acting or purporting to act on behalf of any party to this
     Agreement.

                           (c) Indemnification. Each Panopticon Shareholder
     agrees to indemnify the Representative, ratably in accordance with his or
     her pro rata share of the Escrow Shares, for any and all liabilities,
     obligations, losses, damages, penalties, actions, judgments, suits, costs,
     expenses or disbursements of any kind or nature whatsoever which may at any
     time be imposed on, incurred by

                                      -47-
<PAGE>   48

     or asserted against the Representative in any way relating to or arising
     out of this Agreement or any documents contemplated by or referred to
     herein or therein or the transactions contemplated hereby or thereby or the
     enforcement of any of the terms hereof or thereof or of any such other
     documents; provided, however, that no Panopticon Shareholder shall be
     liable for any of the foregoing to the extent they arise from the
     Representative's gross negligence or willful misconduct. The Representative
     shall be fully justified in refusing to take or to continue to take any
     action hereunder unless he shall first be indemnified to his reasonable
     satisfaction by the Panopticon Shareholders against any and all liability
     and expense which may be incurred by him by reason of taking or continuing
     to take any such action.

                           (d) Resignation or Removal of the Representative.
     Subject to the appointment and acceptance of a successor Representative as
     provided below, the Representative may (i) resign at any time thirty (30)
     days subsequent to giving notice thereof to the Panopticon Shareholders,
     and (ii) be removed at any time with or without cause by action of the
     Panopticon Shareholders who represented a majority of the rights to the
     Escrow Shares. Upon any such resignation or removal, holders of a majority
     of the Escrow Shares may appoint a successor Representative, which
     successor shall be reasonably acceptable to Broadbase. If no successor
     Representative shall have been appointed by the Panopticon Shareholders and
     accepted such appointment within twenty (20) days after the retiring
     Representative's giving of notice of resignation or the Panopticon
     Shareholders' removal of the Representative, then the retiring or removed
     Representative may, on behalf of the Panopticon Shareholders, appoint a
     successor, which shall be reasonably acceptable to Broadbase. Upon the
     acceptance of any appointment as the Representative hereunder, such
     successor Representative shall thereupon succeed to and become vested with
     all the rights, powers, privileges and duties of the retiring or removed
     Representative, and the retiring or removed Representative shall be
     discharged from his duties and obligations hereunder. After any retiring
     Representative's resignation or removal hereunder as the Representative,
     the provisions of Article 12 shall continue in effect for its benefit in
     respect of any actions taken or omitted to be taken by it while it was
     acting as the Representative.

                           (e) Representative as Panopticon Shareholder. The
     Representative, to the extent he is or was a Panopticon Shareholder, shall
     have the same rights and powers under this Agreement as any other
     Panopticon Shareholder and may exercise the same as though he were not
     serving as the Representative, and the term "Panopticon Shareholder" shall
     include the Representative in his capacity as such.


         13.      MISCELLANEOUS

                  13.1 Entire Agreement. The Letter Agreement between Panopticon
and Broadbase dated June 26, 2000 with respect to non-disclosure of confidential
information, this Agreement and the exhibits hereto constitute the entire
understanding and agreement of the parties hereto with respect to the subject
matter hereof and supersede all prior and contemporaneous agreements or
understandings, inducements or conditions, express or implied, written or oral,
between the parties with respect to the subject matter hereof. The express terms
hereof control and supersede any course of performance or usage of trade
inconsistent with any of the terms hereof.

                  13.2 Assignment; Binding Upon Successors and Assigns. Neither
party hereto may assign any of its rights or obligations hereunder without the
prior written consent of the other party

                                      -48-
<PAGE>   49

hereto. This Agreement will be binding upon and inure to the benefit of the
parties hereto and their respective successors and permitted assigns.

                  13.3 No Third Party Beneficiaries. No provisions of this
Agreement are intended, nor will be interpreted, to provide or create any third
party beneficiary rights or any other rights of any kind in any client,
customer, affiliate, stockholder, partner, employee or any party hereto or any
other Person unless specifically provided otherwise herein, and, except as so
provided, all provisions hereof will be personal solely between the parties to
this Agreement.

                  13.4 No Joint Venture. Nothing contained in this Agreement
will be deemed or construed as creating a joint venture or partnership between
the parties hereto. No party is by virtue of this Agreement authorized as an
agent, employee or legal representative of any other party. No party will have
the power to control the activities and operations of any other, and the
parties' status is, and at all times, will continue to be, that of independent
contractors with respect to each other. No party will have any power or
authority to bind or commit any other. No party will hold itself out as having
any authority or relationship in contravention of this Section.

                  13.5 Construction of Agreement. This Agreement has been
negotiated by the respective parties hereto and their attorneys and have been
reviewed by each party hereto. Accordingly, no ambiguity in the language hereof
will be construed for or against either party.

                  13.6 Severability. If any provision of this Agreement, or the
application thereof, is for any reason held to any extent to be invalid or
unenforceable, the remainder of this Agreement and 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
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 the void or unenforceable provision.

                  13.7 Section Headings. A reference to an article, Section or
Exhibit will mean an article or Section in, or an Exhibit to, this Agreement,
unless otherwise explicitly set forth. The titles and headings in this Agreement
are for reference purposes only and will not in any manner limit the
construction of this Agreement. For the purposes of such construction, this
Agreement will be considered as a whole.

                  13.8 Amendment, Extension and Waivers. At any time prior to
the Effective Time, Broadbase, Merger Sub and Panopticon may, to the extent
legally allowed: (a) extend the time for performance of any of the obligations
of the other party; (b) waive any inaccuracies in the representations and
warranties made to such party contained herein or in any document delivered
pursuant thereto; and (c) waive compliance with any of the agreements, covenants
or conditions for the benefit of such party contained herein. Any term or
provision of this Agreement may be amended. Any agreement to any amendment,
extension or waiver will be valid only if set forth in writing and signed by the
party to be bound. The waiver by a party of any breach hereof or default in the
performance hereof will not be deemed to constitute a waiver of any other
default or any succeeding breach or default. The failure of any party to enforce
any of the provisions hereof will not be construed to be a waiver of the right
of such party thereafter to enforce such provisions. The Agreement may be
amended by the parties hereto at any time before or after approval of the
Panopticon Shareholders, but, after such approval, no amendment will be made
which by applicable law requires the further approval of the Panopticon
Shareholders without obtaining such further approval.

                  13.9 Governing Law. The validity of this Agreement the
construction of its terms, and the interpretation and enforcement of the rights
and duties of the parties of this Agreement will be exclusively governed by and
construed in accordance with the internal laws of the State of California, as
applied to agreements entered into solely between residents of and to be
performed entirely in the State of California, without reference to that body of
law relating to conflicts of law or choice of law.

                  13.10 Dispute Resolution. Any dispute hereunder ("DISPUTE")
shall be settled by arbitration, to be held in San Francisco, California, and,
except as herein specifically stated, in accordance with the commercial
arbitration rules of the American Arbitration Association ("AAA RULES") then in
effect. However, in all events, these arbitration provisions shall govern over
any conflicting rules which may now or hereafter be contained in the AAA Rules.
Any judgment upon the award rendered by the arbitrator may be entered in any
court having jurisdiction over the subject matter thereof. The arbitrator shall
have the authority to grant any equitable and legal remedies that would be
available in any judicial proceeding instituted to resolve a Dispute.

                           (a) Compensation of Arbitrator. Any such arbitration
     will be conducted before a single arbitrator who will be compensated for
     his or her services at a rate to be determined by the parties or by the
     American Arbitration Association, but based upon reasonable hourly or daily
     consulting rates for the arbitrator in the event the parties are not able
     to agree upon his or her rate of compensation.

                           (b) Selection of Arbitrator. The American Arbitration
     Association will have the authority to select an arbitrator from a list of
     arbitrators who are lawyers familiar with California contract law;
     provided, however, that such lawyers cannot work for a firm then performing
     services for either party, that each party will have the opportunity to
     make such reasonable objection to any of the arbitrators listed as such
     party may wish and that the American Arbitration Association will select
     the arbitrator from the list of arbitrators as to whom neither party makes
     any such objection. In the event that the foregoing procedure is not
     followed, each party will choose one person from the list of arbitrators
     provided by the American Arbitration Association (provided that such person
     does not have a conflict of interest), and the two persons so selected will
     select from the list provided by the American Arbitration Association the
     person who will act as the arbitrator.

                           (c) Payment of Costs. Broadbase and Panopticon, or
     Broadbase and the Panopticon Shareholders after the Closing, will bear the
     expense of deposits and advances required by the arbitrator in equal
     proportions, but either party may advance such amounts, subject to recovery
     as an addition or offset to any award. The arbitrator will award to the
     prevailing party, as determined by the arbitrator, all costs, fees and
     expenses related to the arbitration, including reasonable fees and expenses
     of attorneys, accountants and other professionals incurred by the
     prevailing party.

                           (d) Burden of Proof. For any Dispute submitted to
     arbitration, the burden of proof will be as it would be if the claim were
     litigated in a judicial proceeding.

                           (e) Award. Upon the conclusion of any arbitration
     proceedings hereunder, the arbitrator will render findings of fact and
     conclusions of law and a written opinion setting forth the basis and
     reasons for any decision reached and will deliver such documents to each
     party to this Agreement along with a signed copy of the award.

                                      -50-
<PAGE>   51

                           (f) Terms of Arbitration. The arbitrator chosen in
     accordance with these provisions will not have the power to alter, amend or
     otherwise affect the terms of these arbitration provisions or the
     provisions of this Agreement.

                           (g) Exclusive Remedy. Except as specifically
     otherwise provided in this Agreement, arbitration will be the sole and
     exclusive remedy of the parties for any Dispute arising out of this
     Agreement.

                  13.11 Other Remedies. Except as otherwise provided in Section
12.3 or elsewhere 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 on such party, and the exercise of any one remedy
will not preclude the exercise of any other.

                  13.12 Notices. Any notice or other communication required or
permitted to be given under this Agreement will be in writing, will be delivered
personally or by mail or express delivery, postage prepaid, and will be deemed
given upon actual delivery or, if mailed by registered or certified mail, on the
third business day following deposit in the mails, addressed as follows:

                               AGREEMENT OF MERGER


         This Agreement of Merger (this "AGREEMENT") is entered into as of
September 15, 2000, by and among Bridge Acquisition Corp., a Delaware
corporation ("BRIDGE") and Panopticon, Inc., a California corporation
("PANOPTICON").

                                    RECITALS

         A. Broadbase Software, Inc., a Delaware corporation, and the parent of
Bridge ("BROADBASE"), Bridge and Panopticon have entered into an Agreement and
Plan of Merger, dated as of July 6, 2000 (the "PLAN OF MERGER"), that provides
for the statutory merger of Bridge with and into Panopticon.

         B. The Boards of Directors of Broadbase, Bridge and Panopticon have
determined it to be advisable and in the respective interests of Broadbase,
Bridge and Panopticon and their stockholders and shareholders, respectively,
that Bridge be merged with and into Panopticon in a reverse triangular merger
(the "MERGER") in accordance with the California General Corporation Law
("CALIFORNIA LAW") and the Delaware General Corporation Law ("DELAWARE LAW") so
that Panopticon will be the surviving corporation of the Merger and will be a
wholly-owned subsidiary of Broadbase subsequent to the Merger.

         NOW, THEREFORE, Bridge and Panopticon hereby agree as follows:

         1. TERMS OF THE MERGER. The effective time of the Merger will be the
time and date on which this Agreement and any required officers' certificates
are filed with the office of the California Secretary of State in accordance
with Section 1108(c) of California Law (the "EFFECTIVE TIME"). On the terms and
subject to the conditions of this Agreement, Bridge will be merged with and into
Panopticon in a statutory merger pursuant to this Agreement in accordance with
applicable provisions of California Law as follows:

                  (a) Conversion of Panopticon Securities. In connection with
     the Merger, Broadbase will issue up to an aggregate of 3,179,810 fully paid
     and nonassessable shares of Broadbase common stock in exchange for all of
     the securities (including shares of common stock, preferred stock, options,
     warrants and other rights) of Panopticon outstanding immediately prior to
     the Effective Time.

                           (i) Conversion of Panopticon Shares. Except as set
         forth in Section 1(c), each share of Panopticon common stock and
         Panopticon Series A Preferred Stock that is issued and outstanding
         immediately prior to the Effective Time, other than shares, if any, for
         which dissenters' rights have been or may be perfected in compliance
         with applicable law, will, by virtue of the Merger and at the Effective
         Time, and without further action on the part of any holder thereof, be
         converted into and represent the right to receive 0.3475 shares of
         Broadbase common stock (the "CONVERSION RATIO").

                           (ii) Dissenting Shares. Notwithstanding anything to
         the contrary contained in this Agreement, any shares of Panopticon
         common stock or Panopticon Series A Preferred Stock that, as of the
         Effective Time, are or may become "dissenting shares" within the
         meaning of Section 1300(b) of the California Corporations Code shall
         not be converted into or represent the right to receive Broadbase
         common stock in accordance with Section 1(a) (or cash in lieu of


<PAGE>   56

         fractional shares in accordance with Section 1(a)(v)), and the holder
         or holders of such shares shall be entitled only to such rights as may
         be granted to such holder or holders in Chapter 13 of the California
         General Corporation Law; provided, however, that if the status of any
         such shares as "dissenting shares," shall not be perfected, or if any
         such shares lose their status as "dissenting shares," then, as of the
         later of the Effective Time or the time of the failure to perfect such
         status or the loss of such status, such shares shall automatically be
         converted into and shall represent only the right to receive (upon
         surrender of the certificate or certificates representing such shares)
         Broadbase common stock in accordance with Section 1(a)(i) (and cash in
         lieu of fractional shares in accordance with Section 1(a)(v)).

                           (iii) Conversion of Panopticon Options and Warrants.

                                    (A) Panopticon Options. Upon the Effective
              Time of the Merger, each option to purchase Panopticon common
              stock (a "PANOPTICON OPTION") that is outstanding immediately
              prior to the Effective Time (whether vested or unvested, and
              whether an incentive or a nonqualified stock option) will be
              assumed by Broadbase and converted into an option (a "BROADBASE
              OPTION") to purchase that number of shares of Broadbase common
              stock that is equal to the number of shares of Panopticon common
              stock that could be purchased pursuant to the Panopticon Option,
              multiplied by the Conversion Ratio, rounded down to the nearest
              whole number. The per share exercise price for each Broadbase
              Option shall be equal to the exercise price per share of such
              Panopticon Option immediately prior to the Effective Time, divided
              by the Conversion Ratio, rounded up to the nearest whole cent. No
              cash will be paid in lieu of fractional shares that are rounded
              down.

                                    (B) Panopticon Warrants. Upon the Effective
              Time of the Merger, each warrant to purchase Panopticon capital
              stock (a "PANOPTICON WARRANT") that is outstanding immediately
              prior to the Effective Time will be assumed by Broadbase and
              converted into a warrant (a "BROADBASE WARRANT") to purchase that
              number of shares of Broadbase common stock that could be purchased
              pursuant to the Panopticon Warrant, multiplied by the Conversion
              Ratio, rounded down to the nearest whole number. The per share
              exercise price of each Broadbase Warrant shall be equal to the
              exercise price per share of such Panopticon Warrant immediately
              prior to the Effective Time, divided by the Conversion Ratio,
              rounded up to the nearest whole cent. No Broadbase Warrants or
              Broadbase common stock shall be issued with respect to the
              Panopticon Warrant held by Kindling I LLC issued August 15, 1999
              (with respect to the remaining shares subject to such warrant) and
              all other Panopticon Warrants which, by their terms, will never
              become exercisable.

                           (iv) Adjustments for Capital Changes. If prior to the
         Merger, Broadbase recapitalizes either through a split-up of the
         outstanding shares of Broadbase common stock into a greater number, or
         through a combination of such outstanding shares into a lesser number,
         or reorganizes, reclassifies or otherwise changes such outstanding
         shares into the same or a different number of shares of other classes
         (other than through a split-up or combination of shares provided for in
         the previous clause), or declares a dividend on its outstanding shares
         payable in shares or securities convertible into shares or sets a
         record date with respect to any of the foregoing that is before the
         Effective Time, the calculation of the Conversion Ratio will be
         adjusted appropriately.

                           (v) No Fractional Shares. Notwithstanding the above
         conversion formulas, no fractional shares of Broadbase common stock
         will be issued in connection with the Merger.


                                      -2-
<PAGE>   57

         In lieu thereof, a Panopticon shareholder who would otherwise be
         entitled to receive a fraction of a share of Broadbase common stock
         (excluding with respect to the Panopticon Options and Panopticon
         Warrants) will instead receive in cash in an amount equal to the
         product obtained by multiplying (i) the closing price of Broadbase
         common stock on the Nasdaq National Market on the last trading day
         before the Effective Time, by (ii) the fraction of a share of Broadbase
         common stock which such holder would otherwise be entitled to receive.

                  (b) Escrow. Broadbase will deduct, on a pro rata basis from
     the number of shares to be issued to each Panopticon shareholder, ten
     percent (10%) of the shares of Broadbase common stock issuable in the
     Merger to the holders of Panopticon common stock immediately prior to the
     Effective Time, rounded to the nearest whole share (the "ESCROW SHARES").
     An escrow agent will hold the Escrow Shares and dividends as collateral for
     Panopticon's indemnification obligations and release shares to satisfy
     valid claims, pursuant to Article 12 of the Plan of Merger. The escrow
     agent will continue to hold Escrow Shares and dividends not released in
     satisfaction of claims until the first anniversary of the Closing Date
     (such period is referred to as the "ESCROW PERIOD"). Stock dividends that
     are issued in order to effect a stock split of Broadbase common stock on
     Escrow Shares paid during the Escrow Period shall also be held in escrow
     until such Escrow Shares are released.

                  (c) Shares of Panopticon Held By Broadbase or Bridge. Each
     share of Panopticon common stock held by Broadbase or Bridge immediately
     prior to the Effective Time will, at the Effective Time, be cancelled,
     without consideration and will not be converted into Broadbase common
     stock.

                  (d) Conversion of Bridge Shares. Each share of Bridge common
     stock that is issued and outstanding immediately prior to the Effective
     Time will, by virtue of the Merger and without further action on the part
     of the sole stockholder of Bridge, be converted into and become one share
     of Panopticon common stock that is issued and outstanding immediately after
     the Effective Time, and the shares of Panopticon common stock into which
     the shares of Bridge common stock are so converted shall be the only shares
     of Panopticon common stock that are issued and outstanding immediately
     after the Effective Time.

                  2. EFFECTS OF THE MERGER. As of the Effective Time: (a) the
separate existence of Bridge will cease and Bridge will be merged with and into
Panopticon, and Panopticon will be the surviving corporation of the Merger; (b)
the Articles of Incorporation of Panopticon will be amended and restated as set
forth in Exhibit A; (c) pursuant to Section 1(a), each share of Panopticon
common stock and Panopticon preferred stock outstanding immediately prior to the
Effective Time will be converted into Broadbase common stock and each Panopticon
Option and Panopticon Warrant will be converted into a Broadbase Option or
Broadbase Warrant, as applicable, except as otherwise provided in Section
1(a)(iii); (d) each share of Bridge common stock outstanding immediately prior
to the Effective Time will be converted into one outstanding share of Panopticon
common stock; (e) the sole director of Bridge prior to the Effective Time will
become the sole director of the surviving corporation and the officers of Bridge
will become the officers of the surviving corporation; and (f) the Merger will,
at and after the Effective Time, have all of the effects provided by applicable
law.

         3. FURTHER ASSURANCES. Bridge agrees that if, at any time after the
Effective Time, Broadbase or Panopticon considers that any further deeds,
assignments or assurances are reasonably necessary or desirable to vest, perfect
or confirm in Panopticon title to any property or rights of Bridge as provided
herein, Broadbase, Panopticon and all of their officers are hereby authorized by
Bridge to execute and deliver all such proper deeds, assignments and assurances
and do all other things necessary or desirable to vest, perfect or confirm title
to such property or rights in Panopticon or Broadbase and

otherwise to carry out the purposes of this Agreement, in the name of Bridge or
otherwise.

the securities to be issued in the Merger, the Stockholder hereby constitutes
and appoints Broadbase, which shall act by and through Rusty Thomas and Eric

administering such plan.

                  4. BUSINESS EXPENSES. During his Employment, the Employee
shall be authorized to incur necessary and reasonable travel, entertainment and
other business expenses in connection with his duties hereunder. The Company
shall reimburse the Employee for such expenses upon presentation of an itemized
account and appropriate supporting documentation, all in accordance with the
Company's generally applicable policies.

                  5. VESTING OF EQUITY IN THE COMPANY. Notwithstanding any
provision in any plan, employment agreement, offer letter or other agreement
between Employee and Panopticon ("Prior Agreements") to the contrary, all of the
Employee's remaining unvested shares of Panopticon common stock, or unvested
options to purchase shares of Panopticon common stock, that are exchanged for
shares of, or options to purchase shares of, Common Stock of the Company on the
date of the Merger ("Restricted Shares") shall remain initially unvested, and
shall at the end of the six month period beginning upon the Effective Time of
the Merger become vested with respect to the number of shares that would have
vested during such six month period pursuant to the vesting schedule in effect
prior to the Merger, and shall thereafter resume vesting in accordance with the
vesting schedule in effect prior to the Merger, for so long as Employee is
continuously providing services to the Company, subject to the provisions of
Section 6. Employee agrees to cancel any right that Employee had to accelerated
vesting of the Restricted Shares as a result of any Prior Agreements. Any
portion of the Restricted Shares that do not vest pursuant to this Section 5
and/or Section 6 shall be forfeited.

                  6. TERM OF EMPLOYMENT.

                           (a) EMPLOYMENT AT WILL. Either party may terminate
the Employee's Employment at any time and for any reason (or no reason), and
with or without cause, by giving the other party notice in writing. The
Employee's Employment with the Company shall be "at will," meaning that either
the Employee or the Company shall be entitled to terminate the Employee's
employment at any time and for any reason, with or without cause. Any contrary
representations that may have been made to the Employee shall be superseded by
this Agreement. This Agreement shall constitute the full and complete agreement
between the Employee and the Company on the "at will" nature of the Employee's
Employment, which may only be changed in an express written agreement signed by
the Employee and a duly authorized officer of the Company.

                           (b) RIGHTS UPON TERMINATION OF EMPLOYMENT. Upon the
termination of the Employee's Employment pursuant to this Section 6, the
Employee shall only be entitled to the compensation, benefits and reimbursements
described in Sections 2, 3, 4, 5 and 6 for the period preceding the effective
date of the termination, and any severance that may be

                                       2

<PAGE>   74

provided pursuant to Section 6(d). The payments under this Agreement shall fully
discharge all responsibilities of the Company to the Employee.

                           (c) TERMINATION OF AGREEMENT. This Agreement shall
terminate when all obligations of the parties hereunder have been satisfied. Any
earlier termination of this employment hereunder shall not limit or otherwise
affect any of the Employee's obligations under Sections 7 and 8.

                           (d) SEVERANCE AND ACCELERATION OF VESTING.

                           (1) CASH SEVERANCE. Notwithstanding the foregoing, if
         Employee's agreement is terminated within the Noncompetition Term (i)
         by Broadbase without "cause", or (ii) by Employee, after "Constructive
         Termination" by Broadbase without cause, then Employee shall be
         entitled to continue receiving base salary for the remaining period of
         the Noncompetition Term, payable on the same schedule as salary is
         generally paid for other Broadbase employees.

                           (2) VESTING ACCELERATION. Notwithstanding the
         foregoing, if Employee's agreement is terminated within the
         Noncompetition Term (i) by Broadbase without "cause", (ii) by Employee,
         after "Constructive Termination" by Broadbase without cause, or (iii)
         due to the death or disability of the Employee, then twenty percent
         (25%) of the then remaining unvested Restricted Shares shall become
         immediately vested and exercisable as of the time of such termination.

                           The term "CAUSE" shall mean:

                                    (i) Any material breach of this Agreement
         between the Employee and the Company, if either (i) such breach is of a
         nature which cannot be cured, or (ii) such breach is of a nature which
         can be cured but which remains uncured fifteen days after written
         notice of breach;

                                    (ii) Any willful misconduct that causes
         significant harm to the Company or that is repeated or continues after
         written notice from the CEO of the Company;

                                    (iii) Conviction of, or a plea of "guilty"
         or "no contest" to, a felony under the laws of the United States or any
         state thereof;

                                    (iv) Misappropriation of the assets of the
         Company or other acts of fraud or embezzlement; or

                                    (v) The repeated or ongoing abuse of alcohol
         or controlled substances that has a repeated or ongoing detrimental
         effect upon the Employee's performance of his duties under this
         Agreement.

                 The term "CONSTRUCTIVE TERMINATION" shall mean:

                                       3

<PAGE>   75

                                    (i) a reduction in base salary or total
         target compensation;

                                    (ii) a change in job location of more than
         30 miles without the Employee's written consent; or

                                    (iii) a significant diminution in
         responsibilities beneath a level of responsibility reasonably
         assignable to the Position.

                           (e) RELEASE. Subsection (d) above shall not apply
unless the Employee (i) has executed a mutual general release (in a form
prescribed by the Company) of all known and unknown claims that he may then have
against the Company or persons affiliated with the Company and which such claims
are in any way related to such termination, Constructive Termination, or Cause
for either, and (ii) has agreed not to prosecute any legal action or other
proceeding based upon any of such claims.

                  7. NON-DISCLOSURE. This Agreement is contingent upon the
Employee's execution of the Company's form of Proprietary Information and
Inventions Agreement, a copy of which is attached hereto as EXHIBIT A. If any
provisions of such Proprietary Information and Inventions Agreement are in
conflict with the provisions of this Agreement, the provisions of this Agreement
shall control.

                  8. NON-COMPETITION, NON-SOLICITATION AND SAVINGS CLAUSE.

                           (a) NONCOMPETITION TERM. For a period of two years
following the Closing Date (the "NONCOMPETITION TERM"), the Employee hereby
agrees that, except as specifically identified in Attachment A or otherwise with
the written consent of Broadbase, directly or indirectly, individually or as an
employee, partner, officer, director or shareholder or in any other capacity
whatsoever of or for any person, firm, partnership, company or corporation other
than Broadbase or its subsidiaries (other than as a holder of less than 1% of
the outstanding capital stock of a publicly-traded company), he shall not:

                                    (i) Own, manage, operate, sell, control or
         participate in the ownership, management, operation, sales or control
         of or be connected in any manner with any business engaged in: (A)
         developing and marketing software in the fields of communication
         personalization solutions, customer marketing solutions and
         personalized purchase recommendations for e-commerce applications; or
         (B) developing any product or providing any service that is
         substantially the same as, is based upon or competes in any material
         respect with any business described in clause (A) of this paragraph;

                                    (ii) Recruit, attempt to hire, solicit,
         assist others in recruiting or hiring, or refer to others concerning
         employment, any person who is or was an employee of Panopticon,
         Broadbase, or any of Broadbase's other subsidiaries, or induce or
         attempt to induce any such employee to terminate his employment with
         Panopticon, Broadbase, or any of Broadbase's other subsidiaries (as the
         case may be);

                                    (iii) Induce or attempt to induce any person
         or entity to curtail or cancel any business or contracts that such
         person or entity had with Panopticon,

                                       4

<PAGE>   76

         Broadbase, or any of Broadbase's other subsidiaries; or

                                    (iv) Contact, solicit or call upon any
         customer or supplier of Panopticon, Broadbase, or any of Broadbase's
         other subsidiaries, on behalf of any other person or entity for the
         purpose of selling or providing any services or products of the type
         normally sold or provided by Panopticon, Broadbase, or any of
         Broadbase's other subsidiaries.

                  (b) The agreements set forth in this Section 8 include within
     their scope all cities, counties, provinces and states of all countries in
     which Broadbase or any of its subsidiaries has engaged in development of
     products or sales or otherwise conducted business or selling or licensing
     efforts at any time during the two years prior to the Closing Date hereof
     or during the Noncompetition Term. The Employee acknowledges that the scope
     and period of restrictions and the geographical area to which the
     restriction imposed in this Section 8 shall apply are fair and reasonable
     and are reasonably required for the protection of Broadbase and that
     Section 8(a) accurately describes the business to which the restrictions
     are intended to apply.

                  (c) It is the desire and intent of the parties that the
     provisions of this Section 8 shall be enforced to the fullest extent
     permissible under applicable law. If any provision of this Agreement or any
     part of any such provision is held under any circumstances to be invalid or
     unenforceable by any arbitrator or court of competent jurisdiction, then:
     (i) such provision or part thereof shall, with respect to such
     circumstances and in such jurisdiction, be modified by such arbitrator or
     court to conform to applicable laws so as to be valid and enforceable to
     the fullest possible extent; (ii) the invalidity or unenforceability of
     such provision or part thereof under such circumstances and in such
     jurisdiction shall not affect the validity or enforceability of such
     provision or part thereof under any other circumstances or in any other
     jurisdiction; (iii) the invalidity or unenforceability of such provision or
     part thereof shall not affect the validity or enforceability of the
     remainder of such provision or the validity or enforceability of any other
     provision of this Section 8. Each provision of this Section 8 is separable
     from every other provision of this Section 8, and each part of each
     provision of this Section 8 is separable from every other part of such
     provision.

                  (d) The Employee acknowledges that any breach of the covenants
of Section 8 will result in immediate and irreparable injury to Broadbase and,
accordingly, consents to the application of injunctive relief and such other
equitable remedies for the benefit of Broadbase as may be appropriate in the
event such a breach occurs or is threatened. The foregoing remedies shall be in
addition to all other legal remedies to which Broadbase may be entitled
hereunder, including, without limitation, monetary damages.



                  9. SUCCESSORS.

                           (a) COMPANY'S SUCCESSORS. This Agreement shall be

all of the Company's business and/or assets. For

administrators, successors, heirs, distributees, devisees and legatees.

                  10. MISCELLANEOUS PROVISIONS.

                           (a) NOTICE. Notices and all other communications

been duly given when personally delivered or when mailed by U.S. registered or
certified mail, return receipt requested and postage prepaid. In the case of the
Employee, mailed notices shall be addressed to him at the home address which he
most recently communicated to the Company in writing. In the case of the
Company, mailed notices shall be addressed to its corporate headquarters, and
all notices shall be directed to the attention of its Secretary.

                           (b) MODIFICATIONS AND WAIVERS. No provision of this
Agreement shall be modified, waived or discharged unless the modification,
waiver or discharge is agreed to in writing and signed by the Employee and by an
authorized officer of the Company (other than the Employee). No waiver by either
party of any breach of, or of compliance with, any condition or provision of

or entered into by either party with respect to the subject matter hereof. This
Agreement, the Merger Agreement and Plan of Reorganization and the Proprietary

shall be interpreted in accordance with the laws of the State of California
(except their provisions governing the choice of law). If any provision of this
Agreement becomes or is deemed invalid, illegal or unenforceable in any
jurisdiction by reason of the scope, extent or duration of its coverage, then
such provision shall be deemed amended to the extent necessary to conform to
applicable law so as to be valid and enforceable or, if such provision cannot be
so amended without materially altering the intention of the parties, then such
provision shall be stricken and the remainder of this Agreement shall continue
in full force and effect. Should there ever occur any conflict between any
provision contained in this Agreement and any present or future statute,

                                       6

law, ordinance or regulation contrary to which the parties have no legal right
to contract, then the latter shall prevail but the provision of this Agreement
affected thereby shall be curtailed and limited only to the extent necessary to

limitation.

                           (f) ARBITRATION. Any controversy or claim arising out
of or relating to this Agreement or the breach thereof, or the Employee's
Employment or the termination thereof, with the exception of any controversy or
claim arising out of or relating to Section 8, shall be settled by arbitration
in San Francisco, California in accordance with the National Rules for the
Resolution of Employment Disputes of the American Arbitration Association. The
decision of the arbitrator shall be final and binding on the parties, and
judgment on the award rendered by the arbitrator may be entered in any court
having jurisdiction thereof. The parties hereby agree that the arbitrator shall
be empowered to enter an equitable decree mandating specific enforcement of the
terms of this Agreement. The Company and the Employee shall share equally all
fees and expenses of the arbitrator. Any controversy or claim arising out of or
relating to Section 8 shall be settled in the appropriate federal or state court
in the State of California. The Company and the Employee hereby consent to
personal jurisdiction of the state and federal courts located in the State of
California for any action or proceeding arising from or relating to this
Agreement or relating to any arbitration in which the parties are participants.

                           (g) NO ASSIGNMENT. This Agreement and all rights and
obligations of the Employee hereunder are personal to the Employee and may not
be transferred or assigned by the Employee at any time. The Company may assign
its rights under this Agreement to any entity that assumes the Company's

                           (h) COUNTERPARTS. This Agreement may be executed in

                                ESCROW AGREEMENT


         THIS ESCROW AGREEMENT is made and entered into as of September 7, 2000
by and among Broadbase Software, Inc., a Delaware corporation ("BROADBASE"),
Stanley Kim, as representative (the "REPRESENTATIVE") of all of the holders of
common stock (the "SHAREHOLDERS") of Panopticon, Inc., a California corporation
("PANOPTICON"), and State Street Bank and Trust Company of California, N.A. (the
"ESCROW AGENT").

                                    RECITALS

         A. Broadbase, Panopticon and Bridge Acquisition Corp., a Delaware
corporation and wholly owned subsidiary of Broadbase ("MERGER SUB"), have
entered into an Agreement and Plan of Merger (the "MERGER AGREEMENT") dated as
of July 6, 2000, pursuant to which Merger Sub will merge with and into
Panopticon in a reverse triangular merger (the "MERGER"), with Panopticon to be
the surviving corporation of the Merger. Capitalized terms used in this
Agreement and not otherwise defined herein, including without limitation
"DAMAGES," "EFFECTIVE TIME," "ESCROW SHARES," "ESCROW PERIOD," "EXCHANGE AGENT"
and "INDEMNIFIED PERSONS," shall have the meanings given to such terms in the
Merger Agreement, a copy of which is attached hereto;

         B. Section 2.2 of the Merger Agreement provides that, at the Effective
Time, Broadbase will be entitled to withhold from the Shareholders a certain
percentage of the shares of Broadbase common stock issuable to the Shareholders
at the Effective Time for the purpose of securing the Shareholders'
indemnification obligations to Broadbase and the other Indemnified Persons
pursuant to the terms and conditions set forth in Article 12 of the Merger
Agreement and in this Agreement;

         C. The Representative is entering into this Agreement on behalf of the
Shareholders as a material inducement and consideration for Broadbase to enter
into the Merger Agreement and to consummate the transactions contemplated
therein and as a material inducement and condition precedent to consummation of
the Merger; and

         D. The parties desire to set forth in this Agreement the terms and
conditions pursuant to which the Escrow Shares shall be deposited in, held in
and delivered from an escrow account.

         NOW, THEREFORE, in consideration of the facts stated in the foregoing
recitals and the mutual promises hereinafter set forth, the parties hereby agree
as follows:


<PAGE>   81

         1.       ESCROW AND INDEMNIFICATION

                  1.1      Establishment of Escrow.

                           (a) Deposit of Escrow Shares. On the Closing Date,
     Broadbase will deposit with the Exchange Agent the Exchange Shares,
     including shares to be subsequently held in escrow. The Exchange Agent will
     give the Escrow Agent prompt written notice of the Closing Date and
     Effective Time of the Merger. Promptly after the Closing, Broadbase will
     provide the Escrow Agent with a spreadsheet listing each Shareholder and
     their interest in the Escrow Shares, and the Exchange Agent will issue to
     the Escrow Agent the Escrow Shares to be withheld from the Shareholders
     upon the surrender of their Panopticon Certificates (including any
     Additional Escrow Shares, as defined in Section 2.1(b)), each registered in
     the name of the applicable Shareholder.

                           (b) Delivery of Stock Powers. Promptly after the
     Effective Time, but in any event within ten (10) business days after
     receipt of the letter of transmittal from the Exchange Agent, each
     Shareholder will deliver to the Escrow Agent three duly endorsed stock
     powers (each a "STOCK POWER") substantially in the form attached as Exhibit
     A and bearing a "medallion" signature guarantee. In the event any
     Additional Escrow Shares are issued, or if the Escrow Agent reasonably
     requires an additional Stock Power to effect a transfer, each Shareholder
     will, upon request, promptly execute and deliver an additional Stock Power
     to the Escrow Agent.

                           (c) Legends. Stock certificates representing Escrow
     Shares will (until they are released to the Shareholders or Broadbase in
     accordance with this Agreement) bear the following legend indicating that
     they are subject to this Agreement (in addition to any other legends which
     might be applicable to such shares):

         "THE SECURITIES REPRESENTED HEREBY MAY BE OFFERED, SOLD OR OTHERWISE
         TRANSFERRED, PLEDGED OR HYPOTHECATED ONLY IN ACCORDANCE WITH THE TERMS
         OF AN ESCROW AGREEMENT AMONG THE ISSUER, THE HOLDER THEREOF AND STATE
         STREET BANK AND TRUST COMPANY OF CALIFORNIA, N.A. A COPY OF SUCH
         AGREEMENT IS ON FILE AT THE PRINCIPAL OFFICE OF THE ISSUER."

                           (d) Investments of Cash. The Escrow Agent shall
     invest cash, if any, held in the Escrow, other than amounts immediately
     distributable by the Escrow Agent, in the SSgA U.S. Treasury Money Market
     Fund. For tax reporting and withholding purposes, the income on such
     investments shall be allocated to the Shareholders in accordance with their
     proportionate interests in the Escrow Shares as set forth in the Escrow
     Ledger (defined in Section 2.2).

                  1.2 Indemnification. Broadbase and the other Indemnified
Persons are entitled to be indemnified by the Shareholders pursuant to the terms
of Article 12 of the Merger Agreement against any Damages during the Escrow
Period. Each of the Shareholders has agreed to the use of the Escrow Shares as
collateral for these indemnity obligations, subject to the terms and limitations
set forth in Article 12 of the Merger Agreement and in this Agreement.

         2.       OWNERSHIP INTERESTS IN AND RELEASE OF
                  THE ESCROW SHARES

                  2.1      Shareholders' Interests in the Escrow Shares.

                           (a) Individual Shareholder Interests. The Escrow
     Shares shall be evidenced by certificates issued in the name of each
     Shareholder. All of the Escrow Shares shall be deemed to be issued and
     outstanding capital stock of Broadbase.

                           (b) Dividends. If Broadbase declares any cash
     dividends, dividends payable in other property or other distributions of
     any kind with respect to Escrow Shares held by the Escrow Agent, Broadbase
     will issue such distributions directly to the Shareholders. Tax-free
     (pursuant to Section 305(a) of the Code) stock dividends declared on the
     Escrow Shares during the Escrow Period in order to effect a stock split of
     Broadbase common stock ("ADDITIONAL ESCROW SHARES") will be delivered
     promptly to the Escrow Agent, held in escrow and distributed to the
     Shareholders in the same manner and in the same proportions as the Escrow
     Shares. For all purposes of this Agreement, the Additional Escrow Shares
     will be treated the same as the Escrow Shares. Unless and until the Escrow
     Agent receives certificates representing Additional Escrow Shares, it may
     assume without inquiry that no Additional Escrow Shares have been, or are
     required to be, issued and that the stock certificates that the Escrow
     Agent possesses represent all of the Escrow Shares.

                           (c) Voting and Other Rights of Ownership. While the
     Escrow Shares remain in the possession of the Escrow Agent, each
     Shareholder beneficially owning Escrow Shares will retain and will be able
     to exercise with respect to such Escrow Shares: (i) voting rights, and (ii)
     all other incidents of ownership of such Escrow Shares which are not
     inconsistent with the terms of this Agreement. Subject to the rights of
     Broadbase under the Merger Agreement and this Agreement, all beneficial
     interest in the Escrow Shares shall be the property of the Shareholders
     from and after the Closing, and Broadbase shall have no interest therein.
     None of the rights of the Shareholders hereunder shall be transferable
     except as otherwise provided by law. Each of the Shareholders shall be
     obligated for all federal, state or local taxes applicable to such
     Shareholder's interest in the Escrow Shares.

                           (d) No Transfers or Encumbrances. Prior to the
     Release Date (or the release of the Escrow Shares, with respect to shares
     held with respect to pending Claims pursuant to Section 2.3(b) of this
     Agreement), Shareholders may not sell, assign or otherwise transfer, nor
     place any Encumbrance on, any Escrow Shares or any beneficial interest
     therein, except: (i) transfers made for estate planning purposes, and (ii)
     transfers by operation of law or laws of descent and distribution. In the
     case of any permitted transfer, the transferee will be subject to all terms
     and provisions of this Agreement. Also, prior to the Release Date (or the
     release of the Escrow Shares, with respect to shares held with respect to
     pending Claims pursuant to Section 2.3(b) of this Agreement), no Escrow
     Shares nor any beneficial interest therein shall be taken or reached by any
     legal or equitable process in satisfaction of any debt or other liability
     of a Shareholder, except to satisfy such Shareholder's obligations under
     Article 12 of the Merger Agreement. The Escrow Agent shall have no
     responsibility for determining or enforcing compliance with this paragraph,
     other than by retaining possession of the Escrow Shares.

                           (e) Right of Escrow Agent to Transfer Shares.
     Notwithstanding the other provisions of this Section 2.1, the Escrow Agent
     shall have the power to effect any transfer of Escrow Shares required by
     this Agreement or necessary for administrative purposes. Broadbase

                                      -3-

shall cooperate with the Escrow Agent in promptly issuing, or causing its
transfer agent to promptly issue, such stock certificates as shall be required
to effect such transfers.

                  2.2 Escrow Ledger. The Escrow Agent shall create and maintain
a written record of each Shareholder's interest in the Escrow shares (the
"ESCROW LEDGER"). The Escrow Agent shall adjust the Escrow Ledger to reflect
changes in each Shareholder's interests in the Escrow Shares. This duty will
continue until the Escrow Agent is required to deliver each Shareholder's Escrow
Shares pursuant to Section 2.3. Absent manifest error, all of the Escrow Agent's
determinations as to the Escrow Ledger shall be binding and conclusive on all
parties to this Agreement. Adjustments to the Escrow Ledger shall include, but
are not limited to, the following:

                           (a) Adjustments for Capital Changes. The Escrow Agent
     shall adjust the Escrow Ledger to reflect the Escrow Agent's receipt of
     Additional Escrow Shares pursuant to Section 2.1(b).

                           (b) Adjustments for Claims. The Escrow Agent shall
     denote Escrow Shares that become subject to pending Contested Claims of
     Broadbase or other Indemnified Persons in each Shareholder's account in the
     Escrow Ledger. The Escrow Agent shall deduct Escrow Shares that are charged
     and allocated to each Shareholder's account pursuant to Article 4 in
     satisfaction of Claims by Broadbase or other Indemnified Persons.

                  2.3 Release of Escrow Shares to Shareholders.

                           (a) Release of Escrow Shares Generally. On the first
     anniversary of the Closing Date (the "RELEASE DATE"), in accordance with
     Section 2.3(c), the Escrow Agent shall certify the Escrow Share balances
     reflected in the Escrow Ledger as of that date and direct the Exchange
     Agent to release the appropriate number of Escrow Shares to each
     Shareholder as designated in the Escrow Ledger, which shall equal such
     Shareholder's original Escrow Shares and Additional Escrow Shares, minus:
     (i) any Escrow Shares attributable to such Shareholder that were returned
     to Broadbase in accordance with Article 4 in satisfaction of a Claim(s) by
     Broadbase or another Indemnified Person(s), and (ii) any Escrow Shares
     attributable to such Shareholder that are subject to pending Claims of
     Broadbase or other Indemnified Persons, to be held pursuant to Section
     2.3(b). The Escrow Agent will direct the Exchange Agent to remove the
     legend described in Section 1.1(c) from all Escrow Shares distributed by
     it.

                           (b) Escrow Shares Subject to Pending Claims.

                                    (i) Upon the Release Date and thereafter,
         the Escrow Agent shall continue to hold any Escrow Shares that are
         subject to pending Claims until the ten business day period in Section
         4.2 expires. At that time, the Escrow Agent shall, as appropriate,
         either instruct the Exchange Agent to distribute the Escrow Shares
         subject to such claim pursuant to Section 4.2, or continue to hold the
         Escrow Shares subject to such Claim pursuant to Section 2.3(b)(ii).

                                    (ii) Upon the Release Date and thereafter,
         the Escrow Agent shall continue to hold any Escrow Shares that are
         subject to Contested Claims of Broadbase or other Indemnified Persons,
         as designated in the Escrow Ledger, until the Escrow Agent receives
         written notice of resolution of each specific Claim pursuant to Section
         4.3(c). After the Escrow Agent receives such notice, in accordance with
         Section 2.3(c), the Escrow Agent shall: (a) either deliver or instruct
         the Exchange Agent to deliver to each Shareholder the number of Escrow

                                      -4-
<PAGE>   84

         Shares, if any, due to each Shareholder in accordance with the
         resolution of the Claim; (b) if applicable, charge and allocate Escrow
         Shares against each Shareholder's account in satisfaction of the
         resolution of the Claim and either return or instruct the Exchange
         Agent to return such Escrow Shares back to Broadbase; and (c) notify
         the Representative in writing of any deduction of Escrow Shares as
         promptly as reasonably practicable. The Escrow Agent shall make the
         appropriate entries in the Escrow Ledger.

                           (c) Procedure for Release and Delivery. Within seven
     (7) days after the Release Date (or with respect to Escrow Shares held
     pursuant to Section 2.3(b), within seven (7) days after the Escrow Agent's
     receipt of written notice of a resolution of a Claim pursuant to Section
     4.3(c)), the Escrow Agent shall instruct the Exchange Agent to deliver the
     Escrow Shares to each Shareholder by mailing (by registered or certified
     mail, return receipt requested) to the address set forth opposite each
     Shareholder's name on the Escrow Ledger (or such other address as provided
     in writing by the Representative to the Escrow Agent). No fractional Escrow
     Shares will be delivered. Broadbase shall have provided to the Escrow Agent
     prior to the expiration of the Escrow Period, and the Escrow Agent shall
     distribute to each Shareholder at the time Escrow Shares, if any, are
     distributed to each Shareholder, cash in lieu of any fractions of Escrow
     Shares in an amount equal to the product of such fraction multiplied by the
     value of an Escrow Share as determined in accordance with Section 4.5. The
     Escrow Agent need not invest cash on hand pending distribution.

         3.       CLAIMS

                  3.1      "Claim" Defined. As used herein, the term "CLAIM"
means a claim for indemnification under Article 12 of the Merger Agreement made
by Broadbase or by any other Indemnified Person. Broadbase agrees that it will
make Claims only as permitted by Article 12 of the Merger Agreement.

                  3.2      Notice of Claim.

                           (a) When a Notice of Claim is Required. An officer of
     Broadbase shall execute and deliver written notice of a Claim (a "NOTICE OF
     CLAIM") to the Representative and the Escrow Agent as promptly as
     reasonably practicable, and in no event after the Release Date, upon:

                                    (i) Broadbase's discovery of any inaccuracy,
         misrepresentation, breach of or default in connection with any of the
         provisions of Section 12.2 of the Merger Agreement; or

                                    (ii) Broadbase's receipt of written notice
         of an order or proceeding brought by any third person against Broadbase
         and/or any Indemnified Person that is based upon or includes assertions
         that would, if true, constitute an inaccuracy, misrepresentation,
         breach of or default in connection with any of the provisions of
         Section 12.2 of the Merger Agreement (a "THIRD PARTY PROCEEDING");

                           (b) Failure to Provide Notice of Claim. Failure to
     provide such notice in a timely manner shall not reduce Broadbase's
     indemnification rights or the indemnification obligations of the
     Shareholders in this Agreement and under the Merger Agreement, unless the
     failure to provide such timely notice impairs the indemnifying party's
     ability to defend the Claim, and then only to the extent of such
     impairment, and except as set forth in Section 3.2(c) below.

                                      -5-

<PAGE>   85


                           (c) All claims for Damages under Article 12 of the
     Merger Agreement must be initiated prior to the expiration of the Escrow
     Period.

                  3.3 Contents of Each Notice of Claim. Each Notice of Claim
given by Broadbase pursuant to Section 3.2 shall be set forth in writing and
shall contain the following information to the extent it is reasonably available
to Broadbase:

                           (a) Statement of Damages. The statement of damages
     shall include: (i) the amount of Damages that Broadbase believes has
     actually been incurred by Broadbase and/or any other Indemnified Person in
     connection with the Claim, reduced by any recovery under policies of
     insurance, and (ii) Broadbase's good faith estimate of the reasonably
     foreseeable maximum amount of the alleged Damages that will ultimately be
     incurred by Broadbase and/or any other Indemnified Person in connection
     with such Claim, including without limitation any Damages from a potential
     Third Party Proceeding.

                           (b) Statement of Basis for Damages. The statement of
     basis for damages shall include: (i) a brief description, in reasonable
     detail, of the facts, circumstances or events giving rise to the alleged
     Damages based on Broadbase's or any other affected Indemnified Person's
     good faith belief, and (ii) if applicable, specific references to the
     provisions of the Merger Agreement alleged to have been breached.

                  3.4 Requirement of Resolution of Claims. The Escrow Agent
shall not act regarding any of the Escrow Shares held pursuant to a Notice of
Claim until such Notice of Claim has been resolved in accordance with Article 4
and, in the case of a Contested Claim, it receives appropriate notice pursuant
to Section 4.3(c).

         4.       RESOLUTION OF CLAIMS

         Any Notice of Claim received by the Representative and the Escrow Agent
pursuant to Article 3 shall be resolved as follows:

                  4.1 Third Party Proceedings. Broadbase shall have the right,
at the Shareholders' expense (to be paid in Escrow Shares subject to the
provisions of Section 12 of the Merger Agreement), to select counsel in
connection with conducting the defense or handling each Third Party Proceeding
and defend or handle such Third Party Proceeding in such manner as Broadbase may
deem reasonably appropriate (including without limitation consent to an entry of
judgement or settlement of such Third Party Proceeding); provided, however, that
Broadbase shall keep the Representative timely apprised of the status of such
Third Party Proceeding. The reasonable costs and expenses incurred by Broadbase
in connection with such defense (including but not limited to reasonable
attorneys' fees, other professionals' and experts' fees and court or arbitration
costs) shall be included in the Damages for which Broadbase may seek indemnity
pursuant to a Claim made by Broadbase or an Indemnified Person hereunder. If
Broadbase defends or handles the Third Party Proceeding, the Representative and
the Shareholders shall cooperate with Broadbase and shall be entitled to
participate in the defense or handling of the Third Party Proceeding with their
own counsel and at their own expense.

         4.2 Uncontested Claims. If, within ten business days after the Escrow
Agent and the Representative receives a Notice of Claim, the Representative does
not contest such Notice of Claim (an "UNCONTESTED CLAIM") in a written notice
delivered to the Escrow Agent pursuant to Section 4.3, then the Escrow Agent
shall: (a) immediately charge and allocate against each Shareholder's accounts
in the

                                      -6-
<PAGE>   86

Escrow Ledger the number of Escrow Shares required, pursuant to Section 4.5, to
satisfy the amount of Damages specified in such Notice of Claim (reduced by any
recovery to date under policies of insurance not reflected in the Notice of
Claim); (b) update the Escrow Ledger to reflect the effect of the deduction
pursuant to Section 2.2(b); and (c) notify the Representative in writing of the
deduction of Escrow Shares as promptly as reasonably practicable. The number of
Escrow Shares deducted hereunder shall be charged to and allocated among the
Shareholders pro rata according to each Shareholder's percentage share, as set
forth in the Escrow Ledger, except as otherwise provided for in Section 12.2 of
the Merger Agreement.

                  4.3 Contested Claims. If Broadbase and the Escrow Agent
receive a written notice contesting all, or a portion of, a Notice of Claim
within the ten business day period described in Section 4.2 (a "CONTESTED
CLAIM"), then the parties will work together in good faith to resolve their
dispute for up to thirty (30) days. If the Contested Claim is still not
resolved, then: (a) such Contested Claim shall be resolved by binding
arbitration in accordance with Section 13.10 of the Merger Agreement, and (b)
the Escrow Agent shall continue to hold the number of Escrow Shares sufficient,
pursuant to Section 4.5, to satisfy the maximum potential award to all
Indemnified Persons under such Claim. Any portion of the Notice of Claim that is
not contested by the Representative in accordance with the foregoing provisions
of this Section 4.3 shall be resolved as an Uncontested Claim in accordance with
Section 4.2. In addition to the provisions of Section 13.10 of the Merger
Agreement, resolution of Contested Claims shall be subject to the following
additional provisions:

                           (a) Award.

                                    (i) Upon the conclusion of any arbitration
         proceedings hereunder, the arbitrator shall render findings of fact and
         conclusions of law and a final written arbitration award setting forth
         the basis and reasons for any decision reached (the "FINAL AWARD") and
         shall deliver such documents to the Escrow Agent, the Representative
         and Broadbase. The Final Award shall constitute a conclusive
         determination of all issues in question, binding upon the
         Representative, the Shareholders and Broadbase, and shall not be
         contested by the Representative, the Shareholders or Broadbase.

                                    (ii) To the extent that the Final Award
         determines that Broadbase or any other Indemnified Person has actually
         incurred Damages in connection with the Contested Claim through the
         date of the Final Award ("INCURRED DAMAGES"), the Final Award will set
         forth and award to Broadbase the amount of such damages, reduced by any
         recovery under policies of insurance to date that were not specified in
         the Notice of Claim. In addition, the Final Award will set forth an
         additional amount of Damages equal to the reasonably foreseeable amount
         of alleged Damages that the arbitrator determines (based on the
         evidence submitted by the parties in the arbitration) are reasonably
         likely to be incurred by Broadbase and any other Indemnified Person as
         a result of the facts giving rise to the Contested Claim ("ESTIMATED
         DAMAGES"), which amount of Estimated Damages may, without limitation,
         include the amount of damages claimed by a third party in an action
         brought against any Indemnified Person based on alleged facts which, if
         true, would give rise to Damages. The Escrow Agent will continue to
         hold Escrow Shares representing the Estimated Damages, in accordance
         with Section 4.5, in escrow, including, if appropriate, beyond the
         expiration of the Escrow Period, until and to the extent that: (A) the
         arbitrator deems that Broadbase has actually incurred such Estimated
         Damages, reduced by any recovery under policies of insurance to date
         that were not specified in the Notice of Claim; (B) the arbitrator
         deems that Broadbase will not actually incur any additional Estimated
         Damages; or (C) the parties come to a written settlement agreement
         pursuant to Section 4.4.

                                      -7-
<PAGE>   87


         Both Incurred Damages and Estimated Damages owed to Indemnified Persons
         are deemed to be Damages for purposes of this Agreement. Upon issuance
         and delivery of the Final Award pursuant to Section 4.3(a)(i), and
         subject to receipt by the Escrow Agent of a written notice of
         resolution of the Claim pursuant to Section 4.3(c), Broadbase will
         immediately be entitled to recover the amount of any Incurred Damages
         awarded to Broadbase under such Final Award.

                           (b) Timing. The Representative, Broadbase and the
     arbitrator shall conclude each arbitration pursuant to this Section 4.3 as
     promptly as practicable. Time is of the essence with regards to all aspects
     of this Agreement.

                           (c) Notice of Resolution of Claim. The Escrow Agent
     shall not deliver Escrow Shares held pursuant to a Contested Claim until
     the Escrow Agent receives appropriate notice. Such notice must consist of:
     (i) written notice of the resolution of such Claim executed by both the
     Representative and Broadbase; (ii) a written settlement agreement pursuant
     to Section 4.4; (iii) delivery to the Escrow Agent of an appropriate final
     non-appealable order by a court of competent jurisdiction; or (iv) delivery
     to the Escrow Agent of a copy of the Final Award of an arbitrator or court.
     The Escrow Agent shall act on such notice without further inquiry in
     accordance with Sections 2.3(b) and (c).

                           (d) Multiplicity of Claims. The assertion of any
     single Claim for indemnification hereunder will not bar Broadbase from
     asserting other Claims hereunder.

                  4.4 Settled Claims. If a Claim (including a Contested Claim)
is settled by a written settlement agreement executed by the Representative and
Broadbase, then the Representative and Broadbase shall promptly deliver such
written settlement agreement to the Escrow Agent with written instructions on
the appropriate charges or adjustments to be made to the Escrow Ledger, and the
Escrow Agent shall promptly release and/or return the Escrow Shares subject to
such claim in accordance with Sections 2.3(b) and 2.3(c). Any settlement which
is effected without the consent of the Representative, which consent shall not
be unreasonably withheld or delayed, shall not be determinative of the amount of
Damages for which indemnification may be sought.

                   4.5 Determination of Number of Escrow Shares for Claims.
Unless a specific number of Escrow Shares is specified, or unless any claim
asserts that a different allocation should be made pursuant to Section 12.2 of
the Merger Agreement, any amount owed to Broadbase under this Agreement will be
immediately payable to Broadbase, subject to Section 4.3(c), by deducting pro
rata from each Shareholder's account in the Escrow Ledger the number of Escrow
Shares equal to: (a) the Damages for that Claim, divided by, (b) the closing
price per share of Broadbase common stock as quoted on the Nasdaq National
Market, and reported in The Wall Street Journal, for the trading day immediately
preceding the Closing Date (subject to adjustment for changes in Broadbase
capital stock as set forth in a certificate of Broadbase delivered to the Escrow
Agent).

                  4.6 Election of Remedies. Broadbase may institute Claims
against the Escrow Shares and in satisfaction thereof may elect to have such
Escrow Shares deducted from the Escrow Ledger, after any notice to the
Representative required hereunder, without making any other claims directly
against the Shareholders and without rescinding or attempting to rescind the
transactions consummated pursuant to the Merger Agreement. Broadbase need not
exhaust any other remedies that may be available to it but may proceed directly
in accordance with the provisions of this Agreement.

         5.       THE ESCROW AGENT

                  5.1 Limitation of Escrow Agent's Liability/Responsibility. In
performing any of its duties under this Escrow Agreement, the Escrow Agent shall
not be liable to any party for damages, losses or expenses, except in the event
of gross negligence or willful misconduct on its part. In no event shall the
Escrow Agent be liable for punitive, consequential or incidental damages. The
Escrow Agent shall not incur any such liability for any action taken or omitted
in reliance upon any instrument, including any written statement or affidavit
provided for in this Escrow Agreement that the Escrow Agent shall in good faith
believe to be genuine; nor will the Escrow Agent be liable or responsible for
forgeries, fraud, impersonations, or determining the scope of any agent's
authority. In addition, the Escrow Agent may consult with legal counsel of its
choice in connection with its duties under this Escrow Agreement and shall be
fully protected in any act taken, suffered, or permitted by it in good faith in
accordance with the advice of counsel. The Escrow Agent is not responsible for
determining and verifying the authority of any person acting or purporting to
act on behalf of any party to this Escrow Agreement. The Escrow Agent undertakes
to perform such duties as are specifically set forth in this Escrow Agreement,
and the Escrow Agent shall not be liable except for the performance of such
duties as are specifically set forth in this Escrow Agreement. No implied
covenants or obligations shall be read into this Escrow Agreement against the
Escrow Agent.

                  5.2 Indemnification of the Escrow Agent.

                           (a) For the purposes of this Section 5.2, references
     to the Escrow Agent shall include the Escrow Agent's officers, directors,
     employees, counsel and agents.

                           (b) Each party to this Agreement other than the
     Escrow Agent (each an "INDEMNIFYING PARTY" and together the "INDEMNIFYING
     PARTIES") will severally reimburse, indemnify and hold harmless the Escrow
     Agent from and against any damage, liability or loss suffered, incurred by,
     or asserted against the Escrow Agent (including amounts paid in settlement
     of any action, suit, proceeding, or claim brought or threatened to be
     brought and including reasonable expenses of legal counsel, collectively,
     "Loss") arising out of, in connection with or based upon any act or
     omission by the Escrow Agent relating in any way to this Agreement or the
     Escrow Agent's services hereunder. This indemnity will exclude any
     indemnification for any Loss arising in whole or in part, directly or
     indirectly, from any fraud, gross negligence or willful misconduct on the
     Escrow Agent's part. Anything in this Agreement to the contrary
     notwithstanding, in no event will the Escrow Agent be liable for special,
     indirect or consequential loss or damage of any kind whatsoever (including
     but not limited to lost profits) suffered by another party to this
     Agreement or by any Shareholder, even if the Escrow Agent has been advised
     of the likelihood of such loss or damage and regardless of the form of
     action. The Escrow Agent's right to indemnification hereunder will survive
     the Escrow Agent's resignation or removal as the Escrow Agent and will
     survive the termination of this Agreement by lapse of time or otherwise.

                           (c) Each Indemnifying Party may participate at its
     own expense in the defense of any claim or action that may be asserted
     against the Escrow Agent related to this Agreement, and if the Indemnifying
     Parties so elect, the Indemnifying Parties may assume the defense of such
     claim or action; provided, however, that, if there exists a conflict of
     interest that would make it inappropriate, in the sole discretion of the
     Escrow Agent, for the same counsel to represent both Escrow Agent and the
     Indemnifying Parties, the Escrow Agent's retention of separate counsel will
     be reimbursable as provided in Section 5.3(b).

<PAGE>   89

                           (d) The Escrow Agent will notify each Indemnifying
     Party by letter, or by telephone or telecopy confirmed by letter, of any
     receipt by Escrow Agent of a written assertion of a claim against the
     Escrow Agent arising out of this Agreement, or any action commenced against
     the Escrow Agent arising out of this Agreement, within five (5) business
     days after the Escrow Agent's receipt of written notice of such claim.
     However, the Escrow Agent's failure to so notify each Indemnifying Party
     will not operate in any manner whatsoever to relieve an Indemnifying Party
     from any liability that it may have to the Escrow Agent under this Section
     5.3 or otherwise unless such failure by the Escrow Agent to give such
     notice materially prejudices such Indemnifying Party.

                  5.4 Compensation and Expenses of Escrow Agent. All fees and
expenses of the Escrow Agent incurred in the ordinary course of performing its
responsibilities hereunder shall be paid by Broadbase upon receipt of a written
invoice by Escrow Agent in accordance with Exhibit B.

                  5.5 Resolution of Conflicting Demands. In the event
conflicting demands are made or conflicting notices are served upon the Escrow
Agent with respect to the Escrow Shares or the Escrow Ledger, the Escrow Agent
shall have the right, at the Escrow Agent's election, to either: (a) give
written notice to the other parties to this Agreement that it has received
conflicting instructions from Broadbase and the Representative and is refraining
from taking action until it receives instructions consented to in writing by
both Broadbase and the Representative, or (b) resign so that a successor escrow
agent can be appointed pursuant to Section 5.6. In the further event that the
Escrow Agent gives written notice under "(a)" above and does not receive
instructions consented to in writing by both Broadbase and the Representative
within thirty (30) calendar days, then the Escrow Agent may file a suit in
interpleader and obtain an order from a court of competent jurisdiction located
in San Mateo County, California, requiring the parties to interplead and
litigate in such court their several claims and rights among themselves. In this
case, the Escrow Agent shall thereby be fully released and discharged from all
further obligations imposed upon it under this Agreement with respect to the
matters that are the subject of such interpleader suit, and Broadbase shall pay
the Escrow Agent all costs, expenses and reasonable attorneys' fees expended or
incurred by the Escrow Agent pursuant to the exercise of Escrow Agent's rights
under this paragraph.

                  5.6 Successor Escrow Agent.

                           (a) In the event the Escrow Agent becomes unavailable
     or unwilling to continue in its capacity as Escrow Agent hereunder, the
     Escrow Agent may resign and be discharged from its duties hereunder by
     giving notice of resignation to the parties to this Agreement, specifying a
     date not less than thirty (30) days following such notice date of when such
     resignation shall take effect and refunding to Broadbase any prepaid but
     unearned fees previously paid by Broadbase to the Escrow Agent hereunder.
     Broadbase shall designate a successor Escrow Agent reasonably satisfactory
     to the Representative prior to the expiration of such ten day period by
     giving written notice to the Escrow Agent and the Representative. If no
     successor escrow agent is named by Broadbase, then the Escrow Agent may
     apply to a court of competent jurisdiction for the appointment of a
     successor Escrow Agent. In either case, the Escrow Agent shall promptly
     transfer the Escrow Shares and Escrow Ledger to the designated successor
     Escrow Agent.

                           (b) In the event Escrow Agent is merged with,
     acquired or otherwise combined with another entity, or Escrow Agent
     transfers all or substantially all of its corporate trust business
     (including the escrow contemplated by this Agreement) to another
     institution, the successor as a result of such transaction will be the
     Escrow Agent hereunder without any further action by the parties hereto.

continuing waiver of any such condition or breach or a waiver of any other

                                                                       EXHIBIT F


                                PANOPTICON, INC.
                        PROPRIETARY INFORMATION AGREEMENT


         As an employee of Panopticon, Inc., its subsidiary or its affiliate
(together, the "Company"), and in consideration of the compensation now and
hereafter paid to me, I agree to the following:

         I.       MAINTAINING CONFIDENTIAL INFORMATION

                  A. Company Information. I agree at all times during the term
of my employment and thereafter to hold in strictest confidence, and not to use,
except for the benefit of the Company, or to disclose to any person, firm or
corporation without the express written authorization of the Board of Directors
of the Company, any trade secrets, confidential knowledge, data or other
proprietary information relating to products, processes, know-how, designs,
formulas, developmental or experimental work, computer programs, data bases,
other original works of authorship, customer lists, business plans, financial
information or other subject matter pertaining to any business of the Company or
any of its clients, consultants or licensees.

                  B. Former Employer Information. I agree that I will not,
during my employment with the Company, improperly use or disclose any
proprietary information or trade secrets of my former or concurrent employers or
companies, if any, and that I will not bring onto the premises of the Company
any unpublished document or any property belonging to my former or concurrent
employers or companies, if any, unless consented to in writing by said employers
or companies.

                  C. Third Party Information. I recognize that the Company has
received and in the future will receive from third parties their confidential or
proprietary information subject to a duty on the Company's part to maintain the
confidentiality of such information and to use it only for certain limited
purposes. I agree that I owe the Company and such third parties, during the term
of my employment and thereafter, a duty to hold all such confidential or
proprietary information in the strictest confidence and not to disclose it to
any person, firm or corporation (except as necessary in carrying out my work for
the Company consistent with the Company's agreement with such third party) or to
use it for the benefit of anyone other than for the Company or such third party
(consistent with the Company's agreement with such third party) without the
express written authorization of the Board of Directors of the Company.

         II.      RETAINING AND ASSIGNING INVENTIONS AND ORIGINAL WORKS

                  A. Inventions and Original Works Retained by Me. I have
attached hereto, as Exhibit A, a list describing all inventions, original works
of authorship, developments, improvements and trade secrets which were made by
me prior to my employment with the Company, which belong to me, which relate to
the Company's proposed business and products, and which are not assigned to the
Company; or, if no such list is attached, I represent that there are no such
inventions.

                  B. Inventions and Original Works Assigned to the Company. I
agree that I will promptly make full written disclosure to the Company, will
hold in trust for the sole right and benefit of the Company, and will assign to
the Company all my right, title and interest in and to any and all inventions,
original works of authorship, developments, improvements or trade secrets which
I may solely or jointly conceive or develop or reduce to practice, or cause to
be conceived or developed or reduced to practice, during the period of time I am
in the employ of the Company. I recognize, however, that Section 2870 of

                                       -3-
<PAGE>   99

the California Labor Code (as set forth in Exhibit B attached hereto) exempts
from this provision any invention as to which I can prove the following:

                           1.       It was developed entirely on my own time;
                                    and

                           2.       No equipment, supplies, facilities or trade
                                    secrets of the Company were used in its
                                    development; and

                           3.       It either:

                                    a.       does not relate, at the time the
                                             invention was conceived or reduced
                                             to practice, to the Company's
                                             business or to the Company's actual
                                             or demonstrably anticipated
                                             research and development; or

                                    b.       does not result from any work
                                             performed by me for the Company.

                  I acknowledge that all original works of authorship which are
made by me (solely or jointly with others) within the scope of my employment and
which are protestable by copyright are "works made for hire," as that term is
defined in the United States Copyright Act (17 USCA, Section 101).

          C. Maintenance of Records. I agree to keep and maintain adequate and
current written records of all inventions and original works of authorship made
by me (solely or jointly with others) during the term of my employment with the
Company. The records will be in the form of notes, sketches, drawings, and any
other format that may be specified by the Company. The records will be available
to and remain the sole property of the Company at all times.

          D. Inventions Assigned to the United States. I agree to assign to the
United States government all my right, title and interest in and to any and all
inventions, original works of authorship, developments, improvements or trade
secrets whenever such full title is required to be in the United States by a
contract between the Company and the United States or any of its agencies.

          E. Obtaining Patent Letters and Copyright Registrations. I agree that
my obligation to assist the Company to obtain United States or foreign patent
letters and copyright registrations covering inventions and original works of
authorship assigned hereunder to the Company shall continue beyond the
termination of my employment, but the Company shall compensate me at a
reasonable rate for time actually spent by me at the Company's request on such
assistance. If the Company is unable because of my mental or physical incapacity
or for any other reason to secure my signature to apply for or to pursue any
application for any United States or foreign patent letters or copyright
registrations covering inventions or original works of authorship assigned to
the Company as above, then I hereby irrevocably designate and appoint the
Company and its duly authorized officers and agents as my agent and attorney in
fact, to act for and in my behalf and stead to execute and file any such
applications and to do all other lawfully permitted acts to further the
prosecution and issuance of patent letters or copyright registrations thereon
with the same legal force and effect as if executed by me. I hereby waive and
quitclaim to the Company any and all claims, of any nature whatsoever, which I
now or may hereafter have for infringement of any patents or copyrights,
resulting from any such application for patent letters or copyright
registrations assigned hereunder to the Company.

                                       -4-
<PAGE>   100

         F. Exception to Assignments. I understand that the provisions of this
Agreement requiring assignment to the Company do not apply to any invention
which qualifies fully under the provisions of Section 2870 of the California
Labor Code, a copy of which is attached hereto as Exhibit B. I will advise the
Company promptly in writing of any inventions, original works of authorship,
developments, improvements or trade secrets that I believe meet the criteria in
Subparagraphs II(B)(1) through (3) above; and I will at that time provide to the
Company in writing all evidence necessary to substantiate that belief. I
understand that the Company will keep in confidence and will not disclose to
third parties without my consent any confidential information disclosed in
writing to the Company relating to inventions that qualify fully under the
provisions of Section 2870 of the California Labor Code.

III. CONFLICTING EMPLOYMENT. I agree that during the term of my employment with
the Company, I will not engage in any other employment, occupation, consulting
or other business activity directly related to the business in which the Company
is now involved or becomes involved during the term of my employment, nor will I
engage in any other activities that conflict with my obligations to the Company.

IV. RETURNING COMPANY DOCUMENTS. I agree that, at the time of leaving the employ
of the Company, I will deliver to the Company (and will not keep in my
possession or deliver to anyone else) any and all devices, records, data, notes,
reports, proposals, lists, correspondence, specifications, drawings, blueprints,
sketches, materials, equipment, other documents or property, or reproductions of
any aforementioned items belonging to the Company, its successors or assigns. In
the event of the termination of my employment, I agree to sign and deliver the
"Termination Certification" attached hereto as Exhibit C.

V. REPRESENTATIONS. I agree to execute any proper oath or verify any proper
document required to carry out the terms of this Agreement. I represent that my
performance of all the terms of this Agreement will not breach any agreement to
keep in confidence proprietary information acquired by me in confidence or in
trust prior to my employment by the Company. I have not entered into, and I
agree I will not enter into, any oral or written agreement in conflict herewith.

VI. GENERAL PROVISIONS.

         A. Governing Law. This Agreement will be governed by the laws of the
State of California.

         B. Entire Agreement. This Agreement sets forth the entire agreement and
understanding between the Company and me relating to the subject matter herein
and merges all prior discussions between us. No modification of or amendment to
this Agreement, nor any waiver of any rights under this agreement, will be
effective unless in writing signed by the party to be charged. Any subsequent
change or changes in my duties, salary or compensation will not affect the
validity or scope of this Agreement.

         C. Severability. If one or more of the provisions in this Agreement are
deemed void by law, then the remaining provisions will continue in full force
and effect.

         D. Successors and Assigns. This Agreement will be binding upon my
heirs, executors, administrators and other legal representatives and will be for
the benefit of the Company, its successors and its assigns.

                       CALIFORNIA LABOR CODE SECTION 2870

                   EMPLOYMENT AGREEMENTS; ASSIGNMENT OF RIGHTS



"(a) Any provision in an employment agreement which provides that an employee
shall assign, or offer to assign, any of his or her rights in an invention to
his or her employer shall not apply to an invention that the employee developed
entirely on his or her own time without using the employer's equipment,
supplies, facilities, or trade secret information except for those inventions
that either:

          (1) Relate at the time of conception or reduction to practice of the
invention to the employer's business, or actual or demonstrably anticipated
research or development of the employer.

          (2) Result from any work performed by the employee for the employer.

(b) To the extent a provision in an employment agreement purports to require an
employee to assign an invention otherwise excluded from being required to be
assigned under subdivision (a), the provision is against the public policy of
this state and is unenforceable."

                           CONVERTIBLE PROMISSORY NOTE

$                                                        Menlo Park, California
 ----------
                                                         -----------


         FOR VALUE RECEIVED, the undersigned Panopticon, Inc., a California
corporation ("BORROWER") promises to pay to the order of Broadbase Software,
Inc., a Delaware corporation ("LENDER"), or the assignee of Lender (including
Lender, the "HOLDER") at Lender's office at 181 Constitution Drive, Menlo Park,
California, or at such other place as Holder may designate, in lawful money of
the United States of America and in immediately available funds, the principal
sum of ______, with interest thereon, to be computed from the date of its
disbursement as set forth herein. Capitalized terms not defined in the text are
defined in Section VI hereof.


         I.       LOAN AND REPAYMENT

                  (a) Loan. Lender shall loan to Borrower the amount set forth
above, provided that (i) the loaned funds may be used by Borrower only for
operating purposes, and (ii) Borrower shall have given Lender a written
affirmation that Borrower has not met either of the default conditions in
Sections IV(a)(ii) or (iii) hereof. Borrower may from time to time during the
term of this Note partially or wholly repay its outstanding borrowing, subject
to all of the limitations, terms and conditions of this Note and of any document
executed in connection with or governing this Note. The unpaid principal balance
of this obligation at any time shall be the total amount advanced hereunder by
Holder less the amount of principal payments made hereon by or for any Borrower,
which balance may be endorsed hereon from time to time by Holder.

                  (b) Repayment. Subject to Section III and Section IV(b) below,
the outstanding balance of this Note shall be due and payable on demand of
Holder at any time on or after November 15, 2000; provided, however, that in the
event that Lender terminates the Merger Agreement pursuant to Section 11.1(b) or
the provisions specifically enumerated in Section 11.4 of the Merger Agreement,
then this Note shall become due and payable by Borrower, subject to Section III
and Section IV(b) below, upon the earliest to occur of: (i) Borrower's next
equity financing of at least $5 million, (ii) an Acquisition of Borrower, or
(iii) the date that is six months after the date of such termination.

                  (c) Advance. Borrower shall provide Lender with Borrower's
wire instructions for Lender to send the advance.
<PAGE>   106

                  (d) Application of Payments. Each payment made on this Note
shall be credited first, to any interest then due and second, to the outstanding
principal balance hereof.

                  (e) Prepayment. Borrower may prepay principal on any portion
of this Note at any time, in any amount and without penalty, upon two days'
written notice to Holder.


         II.      INTEREST

                  (a) Interest. The outstanding principal balance of this Note
shall bear interest (computed on the basis of a 365-day year, actual days
elapsed) at a fixed rate per annum equal to the "PRIME Rate" as reported in the
Wall Street Journal in effect on the first day of the Note ("REGULAR INTEREST").

                  (b) Payment of Interest. Interest accrued on this Note shall
be payable on the Due Date.

                  (c) Default Interest. From and after the maturity date of this
Note, or from and after the occurrence of an Event of Default (as defined
below), the outstanding principal balance of this Note shall, at the election of
Holder, bear interest until paid in full at an increased rate per annum
(computed on the basis of a 365-day year, actual days elapsed) equal to the
lesser of four percent (4%) above the rate of interest from time to time
applicable to this Note or the highest rate of interest permitted under
applicable usury laws (either, as applicable, "DEFAULT INTEREST"). The
imposition of such Default Interest shall be effective as of the date of notice
to Borrower from Holder making such election and specifying such Event of
Default, provided, however, that such Default Interest shall not apply if
Borrower, within ten (10) days of the date of such notice, either (i) cures the
Event of Default or (ii) pays all outstanding principal and Regular Interest
through the date of such payment.


         III.     CONVERSION; ADJUSTMENT

                  (a) Conversion

                           (i) Upon Failure to Pay Amount Due. At any time on or
     after the Due Date, Holder has the right, at Holder's option, prior to the
     repayment of principal and interest by Borrower, to convert the principal
     and accrued interest on this Note, in whole or in part, into Conversion
     Stock at the Conversion Price; provided, however, that Holder shall not be
     entitled to receive the stock certificate representing the shares of
     Conversion Stock to be issued upon conversion of this Note until the
     original of this Note is surrendered to Borrower.

                           (ii) Upon Lender's Next Equity Financing. At any time
     upon or after the closing of the next equity financing of Borrower, Holder
     has the right, at Holder's option, prior to the repayment of principal and
     interest by Borrower, to convert the principal and accrued interest on this
     Note, in whole or in part, into shares of Next Equity Stock at the Next
     Equity Price; provided, however, that Holder shall not be entitled to
     receive the stock certificate representing the shares of Next Equity Stock
     to be issued upon conversion of this Note until the original of this Note
     is surrendered to Borrower. Borrower and Lender will take all steps
     necessary or advisable to effect such result.

                                      -2-
<PAGE>   107

                           (iii) Issuance of Conversion Stock or Next Equity
     Stock. As soon as practicable after conversion of this Note, Borrower at
     its expense will cause to be issued in the name of and delivered to Holder,
     a certificate or certificates for the number of shares of Conversion Stock
     or Next Equity Stock, as applicable, to which the Lender shall be entitled
     upon such conversion (bearing such legends as may be required by applicable
     state and federal securities laws in the opinion of legal counsel of
     Borrower, by Borrower's articles of incorporation or bylaws, or by any
     agreement between Borrower and Lender), together with any other securities
     and property to which Holder is entitled upon such conversion under the
     terms of this Note. Such conversion shall be deemed to have been made
     immediately prior to the close of business on the date that this Note shall
     have been surrendered for conversion, accompanied by written notice of
     election to convert. No fractional shares will be issued upon conversion of
     this Note. If upon any conversion of this Note a fraction of a share would
     otherwise result, then in lieu of such fractional share the Borrower will
     pay the cash value of that fractional share, calculated on the basis of the
     Conversion Price or Next Equity Price, as applicable.

                  (b) Adjustment Provisions. The number and character of shares
of Conversion Stock (which term for purposes of this Section III(b) shall
include Next Equity Stock, if applicable) issuable upon conversion of this Note
(or any shares of stock or other securities or property at the time receivable
or issuable upon conversion of this Note) and the Conversion Price (which term
for purposes of this Section III(b) shall, if applicable, instead mean the Next
Equity Price) therefore, are subject to adjustment upon occurrence of the
following events between the date this Note is issued and the date it is
converted:

                           (i) Adjustment for Stock Splits, Stock Dividends,
     Recapitalizations, etc. The Conversion Price of this Note and the number of
     shares of Conversion Stock issuable upon conversion of this Note (or any
     shares of stock or other securities at the time issuable upon conversion of
     this Note) shall each be proportionally adjusted to reflect any stock
     dividend, stock split, reverse stock split, combination of shares,
     reclassification, recapitalization or other similar event affecting the
     number of outstanding shares of Conversion Stock (or such other stock or
     securities).

                           (ii) Adjustment for Other Dividends and
     Distributions. In case Borrower shall make or issue, or shall fix a record
     date for the determination of eligible holders entitled to receive, a
     dividend or other distribution payable with respect to the Conversion Stock
     that is payable in (A) securities of Borrower (other than issuances with
     respect to which adjustment is made under Section III(b)(i), or (B) assets
     (other than cash dividends paid or payable solely out of retained
     earnings), then, and in each such case, Holder, upon conversion of this
     Note at any time after the consummation, effective date or record date of
     such event, shall receive, in addition to the shares of Conversion Stock
     issuable upon such exercise prior to such date, the securities or such
     other assets of Borrower to which Holder would have been entitled upon such
     date if Holder had converted this Note immediately prior thereto (all
     subject to further adjustment as provided in this Note).

                           (iii) Adjustment for Reorganization, Consolidation,
     Merger. In case of any reorganization of Borrower (or of any other
     corporation the stock or other securities of which are at the time
     receivable on the conversion of this Note), after the date of this Note, or
     in case, after such date, Borrower (or any such corporation) shall
     consolidate with or merge into another corporation or convey all or
     substantially all of its assets to another corporation, then, and in each
     such case, Holder, upon the conversion of this Note (as provided in Section
     III(a)) at any time after the consummation of such reorganization,
     consolidation, merger or conveyance, shall be entitled to

                                      -3-
<PAGE>   108

     receive, in lieu of the stock or other securities and property receivable
     upon the conversion of this Note prior to such consummation, the stock or
     other securities or property to which Holder would have been entitled upon
     the consummation of such reorganization, consolidation, merger or
     conveyance if Holder had converted this Note immediately prior thereto, all
     subject to further adjustment as provided in this Note, and the successor
     or purchasing corporation in such reorganization, consolidation, merger or
     conveyance (if other than Borrower) shall duly execute and deliver to
     Holder a supplement hereto acknowledging such corporation's obligations
     under this Note; and in each such case, the terms of the Note shall be
     applicable to the shares of stock or other securities or property
     receivable upon the conversion of this Note after the consummation of such
     reorganization, consolidation, merger or conveyance.

                           (iv) Conversion of Stock. In case all the authorized
     Conversion Stock of Borrower is converted, pursuant to Borrower's
     certificate of incorporation, into Borrower's common stock or other
     securities or property, or the Conversion Stock otherwise ceases to exist,
     then, in such case, Holder, upon conversion of this Note at any time after
     the date on which the Conversion Stock is so converted or ceases to exist
     (the "TERMINATION DATE"), shall receive, in lieu of the number of shares of
     Conversion Stock that would have been issuable upon such exercise
     immediately prior to the Termination Date (the "FORMER NUMBER OF SHARES OF
     CONVERSION STOCK"), the stock and other securities and property to which
     Holder would have been entitled to receive upon the Termination Date if the
     Lender had converted this Note with respect to the Former Number of Shares
     of Conversion Stock immediately prior to the Termination Date (all subject
     to further adjustment as provided in this Note).

                           (v) Notice of Adjustments. Borrower shall promptly
     give written notice of each adjustment or readjustment of the Conversion
     Price or the number of shares of Conversion Stock or other securities
     issuable upon conversion of this Note. The notice shall describe the
     adjustment or readjustment and show in reasonable detail the facts on which
     the adjustment or readjustment is based.

                           (vi) No Change Necessary. The form of this Note need
     not be changed because of any adjustment in the Conversion Price or in the
     number of shares of Conversion Stock issuable upon its conversion.

                           (vii) Reservation of Stock. If at any time the number
     of shares of Conversion Stock or other securities issuable upon conversion
     of this Note shall not be sufficient to effect the conversion of this Note,
     Borrower will use best efforts to take such corporate action as may, in the
     opinion of its counsel, be necessary to increase its authorized but
     unissued shares of Conversion Stock or other securities issuable upon
     conversion of this Note as shall be sufficient for such purpose.


         IV.      DEFAULT

                  (a) Events of Default. The occurrence of any of the following
shall constitute an "EVENT OF DEFAULT" under this Note:

                           (i) Borrower shall fail to pay when due any

                           (ii) Any representation or warranty made by Borrower
     under shall fail the condition of Section 10.1 of the Merger Agreement.

                           (iii) Any failure to comply with a material
     obligation of this Note, or any failure to perform or comply in with any
     material covenant made by Borrower in the Merger Agreement, provided that,
     any such failure shall not be deemed an Event of Default if cured within
     ten (10) days of the earlier of (A) Borrower's notification to Lender of
     such failure or (B) five (5) business days following Borrower's initial
     awareness of such failure.

                           (iv) Borrower shall suffer or consent to or apply for
     the appointment of a receiver, trustee, custodian or liquidator of itself
     or any of its property, or shall generally fail to pay its debts as they
     become due, or shall make a general assignment for the benefit of
     creditors; Borrower shall file a voluntary petition in bankruptcy, or
     seeking reorganization, in order to effect a plan or other arrangement with
     creditors or any other relief under the Bankruptcy Reform Act, Title 11 of
     the United States Code, as amended or recodified from time to time
     ("BANKRUPTCY CODE"), or under any state or federal law granting relief to
     debtors, whether now or hereafter in effect; or any involuntary petition or
     proceeding pursuant to the Bankruptcy Code or any other applicable state or
     federal law relating to bankruptcy, reorganization or other relief for
     debtors is filed or commenced against Borrower and not dismissed within 90
     days, or Borrower shall file an answer admitting the jurisdiction of the
     court and the material allegations of any involuntary petition; or Borrower
     shall be adjudicated a bankrupt, or an order for relief shall be entered
     against Borrower by any court of competent jurisdiction under the
     Bankruptcy Code or any other applicable state or federal law relating to
     bankruptcy, reorganization or other relief for debtors.

                  (b) Remedies. Upon the occurrence of any Event of Default, the
holder of this Note, at the holder's option, may declare all sums of principal
and interest outstanding hereunder to be immediately due and payable without
presentment, demand, notice of nonperformance, notice of protest, protest or
notice of dishonor, all of which are expressly waived by Borrower, and the
obligation, if any, of the holder to extend any further credit hereunder shall
immediately cease and terminate. Borrower shall pay to the holder immediately
upon demand the full amount of all payments, advances, charges, costs and
expenses, including reasonable attorneys' fees (to include outside counsel fees
and all allocated costs of the holder's in-house counsel), expended or incurred
by the holder in connection with the enforcement of the holder's rights and/or
the collection of any amounts which become due to the holder under this Note,
and the prosecution or defense of any action in any way related to this Note,
including without limitation, any action for declaratory relief, whether
incurred at the trial or appellate level, in an arbitration proceeding or
otherwise, and including any of the foregoing incurred in connection with any
bankruptcy proceeding (including without limitation, any adversary proceeding,
contested matter or motion brought by Lender or any other person) relating to
Borrower or any other person or entity.
