WHEREAS, the Boards of Directors of Hyperion and Arbor deem it advisable and in the best interests of each corporation and its respective stockholders that Hyperion and Arbor combine in order to advance the long-term business interests of Hyperion and Arbor; WHEREAS, the combination of Hyperion and Arbor shall be effected by the terms of this Agreement through a merger in which the stockholders of Hyperion will become stockholders of Arbor (the "Merger"); WHEREAS, upon the closing of the Merger, the name of Arbor shall be changed to "Hyperion Solutions Corporation" (Arbor, from and after the Merger, being sometimes hereinafter referred to as "Newco"); WHEREAS, concurrently with the execution and delivery of this Agreement and as a condition and inducement to each of Hyperion's and Arbor's willingness to enter into this Agreement, Hyperion and Arbor have entered into (a) a Stock Option Agreement dated as of the date of this Agreement and attached hereto as EXHIBIT A (the "Hyperion Stock Option Agreement"), pursuant to which Arbor granted Hyperion an option to purchase shares of common stock of Arbor under certain circumstances, and (b) a Stock Option Agreement dated as of the date of this Agreement and attached hereto as EXHIBIT B (the "Arbor Stock Option Agreement" and, together with the Hyperion Stock Option Agreement, the "Stock Option Agreements"), pursuant to which Hyperion granted Arbor an option to purchase shares of common stock of Hyperion under certain circumstances; WHEREAS, for Federal income tax purposes, it is intended that the Merger shall qualify as a reorganization within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended (the "Code"); and WHEREAS, for accounting purposes, it is intended that the Merger shall be accounted for as a pooling of interests; NOW, THEREFORE, in consideration of the foregoing and the respective representations, warranties, covenants and agreements set forth below, the parties agree as follows: - 1 - 10 ARTICLE I THE MERGER Section 1.01 EFFECTIVE TIME OF THE MERGER. Subject to the provisions of this Agreement, a certificate of merger in such form as is required by the relevant provisions of the Delaware General Corporation Law ("DGCL") (the "Certificate of Merger") shall be duly prepared, executed and acknowledged by the Surviving Corporation (as defined in Section 1.03) and thereafter delivered to the Secretary of State of the State of Delaware, for filing, as provided in the DGCL, as soon as practicable on or after the Closing Date (as defined in Section 1.02). The Merger shall become effective upon the filing of the Certificate of Merger with the Secretary of State of the State of Delaware or at such time thereafter as is provided in the Certificate of Merger (the "Effective Time"). Section 1.02 CLOSING. The closing of the Merger (the "Closing") will take place at 10:00 a.m., California Time, on a date to be specified by Hyperion and Arbor, which shall be no later than the second business day after satisfaction of the latest to occur of the conditions set forth in Sections 7.01, 7.02 and 7.03 (the "Closing Date"), at the offices of Gunderson Dettmer Stough Villeneuve Franklin & Hachigian, LLP, 155 Constitution Drive, Menlo Park, California, unless another date, place or time is agreed to in writing by Hyperion and Arbor. Section 1.03 EFFECTS OF THE MERGER. At the Effective Time (i) the separate existence of Sub shall cease and Sub shall be merged with and into Hyperion (Sub and Hyperion are sometimes referred to below as the "Constituent Corporations" and Hyperion is sometimes referred to below as the "Surviving Corporation"), (ii) the Certificate of Incorporation of Hyperion shall be amended so that Article IV of such Certificate of Incorporation reads in its entirety as follows: "The total number of shares of all classes of stock which the Corporation shall have authority to issue is 1,000, all of which shall consist of Common Stock, par value $.01 per share," and, as so amended, such Certificate of Incorporation shall be the Certificate of Incorporation of the Surviving Corporation, (iii) the Bylaws of the Sub as in effect immediately prior to the Effective Time shall be the Bylaws of the Surviving Corporation, (iv) all the property, rights, privileges, powers and franchises and duties of Sub and Hyperion shall vest in the Surviving Corporation, and (v) all debts, liabilities and duties of Hyperion and Sub shall become the debts, liabilities and duties of the Surviving Corporation. Section 1.04 DIRECTORS AND OFFICERS OF NEWCO. (a) Arbor shall take all actions necessary to cause the directors comprising the full Board of Directors of Arbor at the Effective Time (the "Newco Board") to be - 2 - 11 comprised of seven directors. Initially, four of such directors shall be designated by Hyperion (the "Hyperion Designees") and three of such directors shall be designated by Arbor (the "Arbor Designees"). Hyperion hereby designates the persons listed as such on EXHIBIT C-1 hereto as the initial Hyperion Designees. Arbor hereby designates the persons listed as such on EXHIBIT C-2 hereto as the initial Arbor Designees. Each class of directors of Newco shall consist, at the Effective Time, of the Hyperion Designees and the Arbor Designees as set forth on EXHIBIT C-3. If, prior to the Effective Time, any of the Hyperion Designees or Arbor Designees shall decline or be unable to serve as a Hyperion Designee or an Arbor Designee, Hyperion (if such person was so designated by Hyperion) or Arbor (if such person was so designated by Arbor) shall designate another person to serve in such person's stead, which person shall be reasonably acceptable to the other party. (b) At the Effective Time, Arbor shall cause the persons listed on EXHIBIT C-4 to be named as officers of Newco, holding the positions therein indicated; provided, that if any such persons are unwilling or unable to serve in such capacities, their replacements shall be selected by the Newco Board as constituted at the Effective Time. Newco shall also have such other officers as may be elected by the Newco Board. (c) The foregoing officers and directors of Newco shall hold their positions until their resignation or removal or the election or appointment of their successors in the manner provided by Newco's charter documents and applicable law. Section 1.05 CHARTER AND BYLAWS OF NEWCO. (a) At the Arbor Stockholders' Meeting (as defined in Section 3.16), Arbor shall, in accordance with Section 6.05, propose, among other things, that its Certificate of Incorporation be amended to: (i) change the name of Arbor to "Hyperion Solutions Corporation," (ii) increase the authorized number of shares of Arbor Common Stock to 300,000,000 shares, (iii) create a staggered Board of Directors, and (iv) incorporate into its Certificate of Incorporation indemnification provisions in substantially the form set forth in Arbor's current Bylaws. (b) Arbor shall amend its Bylaws so that the Bylaws of Newco, upon the Effective Time, shall be as set forth as an Exhibit to Section 1.05 to the Arbor Disclosure Schedule (as defined in Article III below). - 3 - 12 ARTICLE II CONVERSION OF SECURITIES Section 2.01 CONVERSION OF CAPITAL STOCK. As of the Effective Time, by virtue of the Merger and without any action on the part of the holder of any shares of Hyperion Common Stock or capital stock of Sub: (a) CAPITAL STOCK OF SUB. Each issued and outstanding share of the capital stock of Sub shall be converted into and become one fully paid and nonassessable share of Common Stock of the Surviving Corporation. (b) CANCELLATION OF TREASURY STOCK AND ARBOR-OWNED STOCK. All shares of Common Stock of Hyperion ("Hyperion Common Stock") that are owned by Hyperion as treasury stock and any shares of Hyperion Common Stock owned by Arbor, Sub or any other wholly-owned Subsidiary (as defined in Section 3.01) of Arbor shall be canceled and retired and shall cease to exist and no stock of Arbor or other consideration shall be delivered in exchange therefor. All shares of Common Stock, par value $.001 per share, of Arbor ("Arbor Common Stock") owned by Hyperion shall be unaffected by the Merger. (c) EXCHANGE RATIO FOR HYPERION COMMON STOCK. Subject to Section 2.02, each issued and outstanding share of Hyperion Common Stock (other than shares to be canceled in accordance with Section 2.01(b)) shall be converted into the right to receive .95 shares (the "Exchange Ratio") of Arbor Common Stock. All such shares of Hyperion Common Stock, when so converted, shall no longer be outstanding and shall automatically be canceled and retired and shall cease to exist, and each holder of a certificate representing any such shares shall cease to have any rights with respect thereto, except the right to receive the shares of Arbor Common Stock and any cash in lieu of fractional shares of Arbor Common Stock to be issued or paid in consideration therefor upon the surrender of such certificate in accordance with Section 2.02, without interest. (d) ADJUSTMENTS TO EXCHANGE RATIO. The Exchange Ratio shall be adjusted to reflect fully the effect of any stock split, reverse split, stock dividend (including any dividend or distribution of securities convertible into Arbor Common Stock or Hyperion Common Stock), reorganization, recapitalization or other like change with respect to Arbor Common Stock or Hyperion Common Stock occurring after the date hereof and prior to the Effective Time. Section 2.02 EXCHANGE OF CERTIFICATES. The procedures for exchanging outstanding shares of Hyperion Common Stock for Arbor Common Stock pursuant to the Merger are as follows: - 4 - 13 (a) EXCHANGE AGENT. As of the Effective Time, Arbor shall deposit with a bank or trust company designated by Hyperion and Arbor (the "Exchange Agent"), for the benefit of the holders of shares of Hyperion Common Stock, for exchange in accordance with this Section 2.02, through the Exchange Agent, (i) certificates representing the shares of Arbor Common Stock (such shares of Arbor Common Stock, together with any dividends or distributions with respect thereto, being hereinafter referred to as the "Exchange Fund") issuable pursuant to Section 2.01 in exchange for outstanding shares of Hyperion Common Stock, and (ii) cash in an amount sufficient to permit payment of cash in lieu of fractional shares pursuant to Section 2.02(e). (b) EXCHANGE PROCEDURES. As soon as reasonably practicable after the Effective Time, but not later than ten business days thereafter, the Exchange Agent shall mail to each holder of record of a certificate or certificates which immediately prior to the Effective Time represented outstanding shares of Hyperion Common Stock (the "Certificates") whose shares were converted pursuant to Section 2.01 into the right to receive shares of Arbor Common Stock (i) a letter of transmittal (which shall specify that delivery shall be effected, and risk of loss and title to the Certificates shall pass, only upon delivery of the Certificates to the Exchange Agent and shall be in such form and have such other provisions as Hyperion and Arbor may reasonably specify) and (ii) instructions for effecting the surrender of the Certificates in exchange for certificates representing shares of Arbor Common Stock (plus cash in lieu of fractional shares, if any, of Arbor Common Stock as provided below). Upon surrender of a Certificate for cancellation to the Exchange Agent or to such other agent or agents as may be appointed by Hyperion and Arbor, together with such letter of transmittal, duly executed, the holder of such Certificate shall be entitled to receive in exchange therefor a certificate representing that number of whole shares of Arbor Common Stock which such holder has the right to receive pursuant to the provisions of this Article II and payment in lieu of fractional shares which the holder of such Certificate has the right to receive pursuant to Section 2.02(e), and the Certificate so surrendered shall immediately be canceled. In the event of a transfer of ownership of Hyperion Common Stock which is not registered in the transfer records of Hyperion, a certificate representing the proper number of shares of Arbor Common Stock may be issued to a transferee if the Certificate representing such Hyperion Common Stock is presented to the Exchange Agent, accompanied by all documents required to evidence and effect such transfer and by evidence that any applicable stock transfer or other applicable taxes have been paid. Until surrendered as contemplated by this Section 2.02, each Certificate shall be deemed at any time after the Effective Time to represent only the right to receive upon such surrender the certificate representing shares of Arbor Common Stock and cash in lieu of any fractional shares of Arbor Common Stock as contemplated by this Section 2.02. - 5 - 14 (c) DISTRIBUTIONS WITH RESPECT TO UNEXCHANGED SHARES. No dividends or other distributions declared or made after the Effective Time with respect to Arbor Common Stock with a record date after the Effective Time shall be paid to the holder of any unsurrendered Certificate with respect to the shares of Arbor Common Stock represented thereby and no cash payment in lieu of fractional shares shall be paid to any such holder pursuant to subsection (e) below until the holder of record of such Certificate shall surrender such Certificate. Subject to the effect of applicable laws, following surrender of any such Certificate, there shall be paid to the record holder of the certificates representing whole shares of Arbor Common Stock issued in exchange therefor, without interest, (i) at the time of such surrender, the amount of any cash payable in lieu of a fractional share of Arbor Common Stock to which such holder is entitled pursuant to subsection (e) below and the amount of dividends or other distributions with a record date after the Effective Time previously paid with respect to such whole shares of Arbor Common Stock, and (ii) at the appropriate payment date, the amount of dividends or other distributions with a record date after the Effective Time but prior to surrender and a payment date subsequent to surrender payable with respect to such whole shares of Arbor Common Stock. (d) NO FURTHER OWNERSHIP RIGHTS IN HYPERION COMMON STOCK. All shares of Arbor Common Stock issued upon the surrender for exchange of Certificates in accordance with the terms hereof (including any cash paid pursuant to subsection (c) or (e) of this Section 2.02) shall be deemed to have been issued in full satisfaction of all rights pertaining to such shares of Hyperion Common Stock, subject, however, to the Surviving Corporation's obligation to pay any dividends or make any other distributions with a record date prior to the Effective Time which may have been declared or made by Hyperion on such shares of Hyperion Common Stock in accordance with the terms of this Agreement (to the extent permitted under Section 5.01) prior to the date hereof and which remain unpaid at the Effective Time, and from and after the Effective Time there shall be no further registration of transfers on the stock transfer books of the Surviving Corporation of the shares of Hyperion Common Stock which were outstanding immediately prior to the Effective Time. If, after the Effective Time, Certificates are presented to the Surviving Corporation for any reason, they shall be canceled and exchanged as provided in this Section 2.02. (e) NO FRACTIONAL SHARES. No certificate or scrip representing fractional shares of Arbor Common Stock shall be issued upon the surrender for exchange of Certificates, and such fractional share interests will not entitle the owner thereof to vote or to any other rights of a stockholder of Arbor. Notwithstanding any other provision of this Agreement, each holder of shares of Hyperion Common Stock exchanged pursuant to the Merger who would otherwise have been entitled to receive a fraction of a share of Arbor Common Stock (after taking into account all Certificates delivered by such holder) shall receive, in lieu thereof, cash (without interest) in an amount equal to such fractional part of a share of Arbor Common Stock multiplied by the average of the last reported sales prices of Arbor Common - 6 - 15 Stock, as reported on the Nasdaq National Market, on each of the ten trading days immediately preceding the Closing Date. (f) TERMINATION OF EXCHANGE FUND. Any portion of the Exchange Fund which remains undistributed to the stockholders of Hyperion for 180 days after the Effective Time shall be delivered to Arbor, upon demand, and any stockholders of Hyperion who have not previously complied with this Section 2.02 shall thereafter look only to Arbor for payment of their claim for Arbor Common Stock, any cash in lieu of fractional shares of Arbor Common Stock and any dividends or distributions with respect to Arbor Common Stock. (g) NO LIABILITY. To the extent permitted by applicable law, neither Arbor nor Hyperion shall be liable to any holder of shares of Arbor Common Stock or Hyperion Common Stock, as the case may be, for such shares (or dividends or distributions with respect thereto) delivered to a public official pursuant to any applicable abandoned property, escheat or similar law. (h) WITHHOLDING RIGHTS. Each of Arbor and the Surviving Corporation shall be entitled to deduct and withhold from the consideration otherwise payable pursuant to this Agreement to any holder of shares of Hyperion Common Stock such amounts as it is required to deduct and withhold with respect to the making of such payment under the Code, or any provision of state, local or foreign tax law. To the extent that amounts are so withheld by the Surviving Corporation or Arbor, as the case may be, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the holder of the shares of Hyperion Common Stock in respect of which such deduction and withholding was made by the Surviving Corporation or Arbor, as the case may be. (i) LOST CERTIFICATES. If any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the person claiming such Certificate to be lost, stolen or destroyed and, if required by the Surviving Corporation, the posting by such person of a bond in such reasonable amount as the Surviving Corporation may direct as indemnity against any claim that may be made against it with respect to such Certificate, the Exchange Agent will issue in exchange for such lost, stolen or destroyed Certificate the shares of Arbor Common Stock and any cash in lieu of fractional shares, and unpaid dividends and distributions on shares of Arbor Common Stock deliverable in respect thereof pursuant to this Agreement. (j) AFFILIATES. Notwithstanding anything herein to the contrary, Certificates surrendered for exchange by any Affiliate (as defined in Section 6.10) of Hyperion shall not be exchanged until Arbor has received an Affiliate Agreement (as defined in Section 6.10) from such Affiliate. - 7 - 16 ARTICLE III REPRESENTATIONS AND WARRANTIES OF ARBOR AND SUB Arbor and Sub represent and warrant to Hyperion that the statements contained in this Article III are true and correct except as set forth herein and in the disclosure schedule delivered by Arbor to Hyperion prior to the execution and delivery of this Agreement (the "Arbor Disclosure Schedule"). The Arbor Disclosure Schedule shall be arranged in sections and paragraphs corresponding to the numbered and lettered sections and paragraphs contained in this Article III and the disclosure in any section or paragraph shall qualify other sections and paragraphs in this Article III only to the extent that it is reasonably apparent from a reading of such disclosure that it also qualifies or applies to such other sections and paragraphs. Section 3.01 ORGANIZATION OF ARBOR AND SUB. Each of Arbor and Sub and Arbor's other Subsidiaries (as defined below) is a corporation duly organized, validly existing and in good standing under the laws of the jurisdiction of its incorporation, has all requisite corporate power to own, lease and operate its property and to carry on its business as now being conducted and as proposed to be conducted, and is duly qualified to do business and is in good standing as a foreign corporation in each jurisdiction in which the failure to be so qualified would have an Arbor Material Adverse Effect (as defined below). Except as set forth in the Arbor SEC Reports (as defined in Section 3.04) filed prior to the date hereof, neither Arbor nor any of its Subsidiaries directly or indirectly owns any equity or similar interest in, or any interest convertible into or exchangeable or exercisable for, any corporation, partnership, joint venture or other business association or entity, excluding securities in any publicly traded company held for investment by Arbor and comprising less than five percent (5%) of the outstanding stock of such company. As used in this Agreement, the word "Subsidiary" means, with respect to any party, any corporation or other organization, whether incorporated or unincorporated, of which (a) such party or any other Subsidiary of such party is a general partner (excluding partnerships, the general partnership interests of which held by such party or any Subsidiary of such party do not have a majority of the voting interest in such partnership) or (b) at least a majority of the securities or other interests having by their terms ordinary voting power to elect a majority of the Board of Directors or others performing similar functions with respect to such corporation or other organization is directly or indirectly owned or controlled by such party or by any one or more of its Subsidiaries, or by such party and one or more of its Subsidiaries. As used in this Agreement, any reference to a party's "knowledge" means, with respect to a matter, such party's actual knowledge after due and diligent inquiry of officers, directors and other employees of such party and its Subsidiaries reasonably believed to have knowledge of such matter. For purposes of this Agreement, the term "Arbor Material Adverse Effect" means any effect that is, or would reasonably be expected to be, materially adverse to the business, properties, financial condition or results of - 8 - 17 operations of Arbor and its Subsidiaries, taken as a whole; provided, however, that (i) any adverse change, event or effect that is demonstrated to be primarily caused by conditions affecting the United States economy generally or the economy of any nation or region in which Arbor or any of its Subsidiaries conducts business that is material to the business of Arbor and its Subsidiaries, taken as a whole, shall not be taken into account in determining whether there has been or would be an "Arbor Material Adverse Effect" on or with respect to Arbor and its Subsidiaries, taken as a whole, (ii) any adverse change, event or effect that is demonstrated to be primarily caused by conditions generally affecting the enterprise software industry shall not be taken into account in determining whether there has been or would be an "Arbor Material Adverse Effect" on or with respect to Arbor and its Subsidiaries, taken as a whole, (iii) any adverse change, event or effect that is demonstrated to be primarily caused by the announcement or pendency of the Merger shall not be taken into account in determining whether there has been or would be an "Arbor Material Adverse Effect" on or with respect to Arbor and its Subsidiaries, taken as a whole, and (iv) any adverse change in the stock price of Arbor as quoted on the Nasdaq National Market shall not be taken into account in determining whether there has been or would be an "Arbor Material Adverse Effect" on or with respect to Arbor and its Subsidiaries, taken as a whole. Section 3.02 ARBOR CAPITAL STRUCTURE. (a) The authorized capital stock of Arbor consists of 50,000,000 shares of Common Stock, $.001 par value, and 5,000,000 shares of Preferred Stock, $.001 par value ("Arbor Preferred Stock"). As of March 31, 1998, (i) 11,402,591 shares of Arbor Common Stock were issued and outstanding, all of which are validly issued, fully paid and nonassessable, (ii) 1,774,402 shares of Arbor Common Stock were reserved for issuance upon conversion of Arbor's 4 1/2% Convertible Subordinated Notes Due 2005 in the original principal amount of $100,000,000 (the "Arbor Notes") and (iii) no shares of Arbor Common Stock were held in the treasury of Arbor or by Subsidiaries of Arbor.

All of the outstanding shares of capital stock of each of Arbor's Subsidiaries are duly authorized, validly issued, fully paid and nonassessable and all such shares (other than directors' qualifying shares in the case of foreign Subsidiaries) are owned by Arbor or another Subsidiary free and clear of all security interests, liens, claims, pledges, agreements, limitations in Arbor's voting rights, charges or other encumbrances of any nature.

The Arbor SEC Reports (i) at the time filed or, with respect to registration statements filed with the SEC under the Securities Act, as of the effective date thereof, complied in all material respects with the applicable requirements of the Securities Act of 1933, as amended (the "Securities Act"), and the Exchange Act, as the case may be, and (ii) did not at the time they were filed (or if amended or superseded by a filing prior to the date of this Agreement, then on the date of such filing) contain any untrue statement of a material fact or omit to state a material fact required to be stated in such Arbor SEC Reports or necessary in order to make the statements in such Arbor SEC Reports, in the light of the circumstances under which they were made, not misleading.

(b) Each of the consolidated financial statements (including, in each case, any related notes) contained in the Arbor SEC Reports complied as to form in all material respects with the applicable published rules and regulations of the SEC with respect thereto, was prepared in accordance with U.S. generally accepted accounting principles ("GAAP") applied on a consistent basis throughout the periods involved (except as may be indicated in the notes to such financial statements or, in the case of unaudited statements, as permitted by Form 10-Q of the SEC) and fairly presented the consolidated financial position of Arbor and its Subsidiaries as of the dates and the consolidated results of its operations and cash flows for the periods indicated, except that the unaudited interim financial statements were or are subject to normal and recurring year-end adjustments which were not or are not expected to be material in amount. The unaudited balance sheet of Arbor as of March 31, 1998 is referred to herein as the "Arbor Balance Sheet." Section 3.05 NO UNDISCLOSED LIABILITIES. Except as disclosed in the Arbor SEC Reports filed prior to the date hereof, and except for normal or recurring liabilities incurred since March 31, 1998 in the ordinary course of business consistent with past practices, Arbor and its Subsidiaries do not have any liabilities, either accrued, contingent or otherwise (whether or not required to be reflected in financial statements in accordance with GAAP), and whether due or to become due, which individually or in the aggregate are reasonably likely to have an Arbor Material Adverse Effect. Section 3.06 ABSENCE OF CERTAIN CHANGES OR EVENTS. Except as disclosed in the Arbor SEC Reports filed prior to the date hereof, during the period commencing on the date of the Arbor Balance Sheet and ending on the date of this Agreement, Arbor and its Subsidiaries have conducted their businesses only in the ordinary course and - 12 - 21 in a manner consistent with past practice and, during such period, there has not been (i) any change in the financial condition, results of operations, business or properties of Arbor and its Subsidiaries, taken as a whole, which has had or could reasonably be expected to have an Arbor Material Adverse Effect; (ii) any damage, destruction or loss (whether or not covered by insurance) with respect to Arbor or any of its Subsidiaries having an Arbor Material Adverse Effect; (iii) any material change by Arbor in its accounting methods, principles or practices to which Hyperion has not previously consented in writing; (iv) any revaluation by Arbor of any of its assets having an Arbor Material Adverse Effect; or (v) any other action or event that would have required the consent of Hyperion pursuant to Section 5.01 of this Agreement had such action or event occurred after the date of this Agreement and that, in the case of this clause (v), individually or in the aggregate, has had or is reasonably likely to have an Arbor Material Adverse Effect. Section 3.07 TAXES. (a) For the purposes of this Agreement, a "Tax" or, collectively, "Taxes" means any and all material federal, state, local and foreign taxes, assessments and other governmental charges, duties, impositions and liabilities, including taxes based upon or measured by gross receipts, income, profits, sales, use and occupation, and value added, ad valorem, transfer, gains, franchise, withholding, payroll, recapture, employment, excise, unemployment insurance, social security, business license, occupation, business organization, stamp, environmental and property taxes, together with all interest, penalties and additions imposed with respect to such amounts and any obligations under any agreements or arrangements with any other person with respect to such amounts and including any liability for taxes of a predecessor entity. "Tax Returns" means all reports, returns, declarations, statements or other information required to be supplied to a taxing authority in connection with Taxes. (b) Each of Arbor and its Subsidiaries has filed all Tax Returns that it was required to file, and, except to the extent that a reserve for Taxes was reflected on the Arbor Balance Sheet (exclusive of any accruals for "deferred taxes" or similar items that reflect timing differences between Tax and financial accounting principles), all such Tax Returns were correct and complete. Each group of corporations with which Arbor or any Subsidiary has filed (or was required to file) consolidated, combined, unitary or similar Tax Returns (an "Arbor Affiliated Group") has filed all such Tax Returns that it was required to file with respect to any period in which Arbor or a Subsidiary was a member of such Arbor Affiliated Group (an "Arbor Affiliated Period"), and, except to the extent that a reserve for Taxes was reflected on the Arbor Balance Sheet (exclusive of any accruals for "deferred taxes" or similar items that reflect timing differences between Tax and financial accounting principles), all such Tax Returns were correct and complete. Except to the extent that a reserve for Taxes was reflected on the Arbor Balance Sheet (exclusive of any accruals for "deferred taxes" or similar items that reflect timing differences between Tax and financial - 13 - 22 accounting principles), each of Arbor and its Subsidiaries has paid all Taxes (whether or not shown on such Tax Returns) that were due and payable, and each Arbor Affiliated Group has paid all Taxes (whether or not shown on such Tax Returns) that were due and payable with respect to all Arbor Affiliated Periods and with respect to which Arbor or any of its Subsidiaries may be liable by operation of law or otherwise. The unpaid Taxes of Arbor and the Subsidiaries for Tax periods through the date of the Arbor Balance Sheet do not exceed the accruals and reserves for Taxes set forth on the Arbor Balance Sheet (exclusive of any accruals for "deferred taxes" or similar items that reflect timing differences between Tax and financial accounting principles). The unpaid Taxes of Arbor and the Subsidiaries for Tax periods from the date of the Arbor Balance Sheet through the Closing Date are attributable solely to the conduct of their businesses in the ordinary course and in a manner consistence with past practices. All Taxes that Arbor or any Subsidiary is or was required by law to withhold or collect have been duly withheld or collected and, to the extent required, have been paid to the proper Governmental Entity. Each of the representations contained in this Section 3.07(b) shall be limited in its application to items which are reasonably likely, individually or in the aggregate, to have an Arbor Material Adverse Effect. (c) Arbor is not and never has been a party to or bound by any Tax indemnity, Tax sharing or Tax allocation agreement (whether written or unwritten or arising under operation of federal law as a result of being a member of a group filing consolidated Tax Returns, under operation of certain state laws as a result of being a member of a unitary group, or under comparable laws of other states or foreign jurisdictions) which includes a party other than Arbor nor does Arbor owe any amount under any such agreement. No examination or audit by any Governmental Entity of any Tax Return of Arbor, any of its Subsidiaries or any Arbor Affiliated Group with respect to an Arbor Affiliated Period is currently in progress or, to the knowledge of Arbor and its Subsidiaries, threatened or contemplated, in each case, which involve claims that individually or in the aggregate are reasonably likely to have an Arbor Material Adverse Effect. Neither Arbor nor any of its Subsidiaries has been informed by any jurisdiction that the jurisdiction believes that Arbor or any of its Subsidiaries was required to file any Tax Return that was not filed which failure or failures individually, or in the aggregate, are reasonably likely to have an Arbor Material Adverse Effect.

Section 3.08 PROPERTIES. (a) Arbor does not own of record any real property. (b) All material real property leases of Arbor and its Subsidiaries are in good standing, valid and effective in accordance with their respective terms, and neither Arbor nor any of its Subsidiaries is in default under any of such leases, except where the lack of such good standing, validity or effectiveness or the existence of such default would not be reasonably likely to have an Arbor Material Adverse Effect. Section 3.09 INTELLECTUAL PROPERTY. (a) Arbor and its Subsidiaries own, or are licensed or otherwise possess legally enforceable rights to use, all patents, trademarks, trade names, service marks, copyrights and mask works, any applications for and registrations of such patents, trademarks, trade names, service marks, copyrights and mask works, and all processes, formulae, methods, schematics, technology, know-how, computer software programs or applications and tangible or intangible proprietary information or material that are necessary to conduct the business of Arbor and its Subsidiaries as currently conducted, or planned to be conducted, the absence of which would be reasonably likely to have an Arbor Material Adverse Effect (the "Arbor Intellectual Property Rights"). (b) Neither Arbor nor any of its Subsidiaries is, or will as a result of the execution and delivery of this Agreement or the performance of Arbor's obligations under this Agreement or otherwise be, in breach of any license, sublicense or other agreement relating to the Arbor Intellectual Property Rights, or any material licenses, sublicenses and other agreements as to which Arbor or any of its Subsidiaries is a party and pursuant to which Arbor or any of its Subsidiaries is authorized to use any third party patents, trademarks or copyrights ("Arbor Third Party Intellectual Property Rights"), including software that is used in the manufacture of, incorporated in, or forms a part of any product sold by or expected to be sold by Arbor or any of its Subsidiaries, the breach of which would be reasonably likely to have an Arbor Material Adverse Effect. (c) All patents, registered trademarks, service marks and copyrights which are held by Arbor or any of its Subsidiaries and which are material to the business of Arbor and its Subsidiaries, taken as a whole, are valid and subsisting. Arbor (i) has - 15 - 24 not been sued in any suit, action or proceeding, or received in writing any claim or notice, which involves a claim of infringement of any patents, trademarks, service marks, copyrights or violation of any trade secret or other proprietary right of any third party; and (ii) has no knowledge that the manufacturing, marketing, licensing or sale of its products infringes any patent, trademark, service mark, copyright, trade secret or other proprietary right of any third party, which infringement would reasonably be expected to have an Arbor Material Adverse Effect.

Arbor has not breached, or received in writing any claim or notice that it has breached, any of the terms or conditions of any agreement, contract or commitment filed as an exhibit to the Arbor SEC Reports ("Arbor Material Contracts") in such a manner as, individually or in the aggregate, are reasonably likely to have an Arbor Material Adverse Effect. Each Arbor Material Contract that has not expired by its terms is in full force and effect. Section 3.11 LITIGATION. Except as described in the Arbor SEC Reports filed prior to the date hereof, there is no action, suit or proceeding, claim, arbitration or investigation against Arbor or any of its Subsidiaries pending or as to which Arbor or any such Subsidiary has received any written notice of assertion, which, individually or in the aggregate, is reasonably likely to have an Arbor Material Adverse Effect or a material adverse effect on the ability of Arbor to consummate the transactions contemplated by this Agreement.

All of the outstanding shares of capital stock of each of Hyperion's Subsidiaries are duly authorized, validly issued, fully paid and nonassessable and all such shares (other than directors' qualifying shares in the case of foreign Subsidiaries) are owned by Hyperion or another Subsidiary free and clear of all security interests, liens, claims, pledges, agreements, limitations in Hyperion's voting rights, charges or other encumbrances of any nature.

Except as set forth in the Hyperion SEC Reports filed prior to the date hereof, in the Arbor Stock Option Agreement or disclosed in Section 4.02 of the Hyperion Disclosure Schedule, there are no options, warrants, equity securities, calls, rights, commitments or agreements of any character to which Hyperion or any of its Subsidiaries is a party or by which it is bound obligating Hyperion or any of its Subsidiaries to issue, deliver or sell, or cause to be issued, delivered or sold, additional shares of capital stock of Hyperion or any of its Subsidiaries or obligating Hyperion or any of its Subsidiaries to grant, extend, accelerate the vesting of, change the price of, or otherwise amend or enter into any such option, warrant, equity security, call, right, commitment or agreement.

The execution and delivery of this Agreement and the Arbor Stock Option Agreement and the consummation of the transactions contemplated by this Agreement and the Arbor Stock Option Agreement by Hyperion have been duly authorized by all necessary corporate action on the part of Hyperion, subject only to the approval of the Merger by Hyperion's stockholders under the DGCL. This Agreement and the Arbor Stock Option Agreement have been duly executed and delivered by Hyperion and constitute the valid and binding obligation of Hyperion, enforceable in accordance with their terms, subject to the Bankruptcy and Equity Exception. (b) The execution and delivery of this Agreement and the Arbor Stock Option Agreement by Hyperion does not, and the consummation of the transactions contemplated by this Agreement and the Arbor Stock Option Agreement will not, (i) conflict with, or result in any violation or breach of, any provision of the Certificate of Incorporation or Bylaws of Hyperion, each as amended to date, (ii) result in any violation of, or default under or breach of, or constitute (with or without notice or lapse of time, or both) a default (or give rise to a right of termination, cancellation or acceleration of any obligation or loss of any material benefit) under, or require a consent or waiver under, any of the terms, conditions or provisions of any note, bond, mortgage, indenture, lease, contract or other agreement, instrument or obligation to which Hyperion or any of its Subsidiaries is a party or by which any of them or any of their properties or assets may be bound, or (iii) conflict with or violate any permit, concession, franchise, license, judgment, order, decree, statute, law, ordinance, rule or regulation applicable to Hyperion or any of its Subsidiaries or any of its or their properties or assets, except in the case of clauses (ii) and (iii) for any such conflicts, violations, defaults, terminations, cancellations or - 23 - 32 accelerations that are not, individually or in the aggregate, reasonably likely to have a Hyperion Material Adverse Effect.

Section 4.04 SEC FILINGS; FINANCIAL STATEMENTS. (a) Hyperion has filed and made available to Arbor all forms, reports and documents required to be filed by Hyperion with the SEC since July 1, 1995 other than registration statements on Form S-8 (collectively, the "Hyperion SEC Reports"). The Hyperion SEC Reports (i) at the time filed or, with respect to registration statements filed with the SEC under the Securities Act, as of the effective date thereof, complied in all material respects with the applicable requirements of the Securities Act and the Exchange Act, as the case may be, and (ii) did not at the time they were filed (or if amended or superseded by a filing prior to the date of this Agreement, then on the date of such filing) contain any untrue statement of a material fact or omit to state a material fact required to be stated in such Hyperion SEC Reports or necessary in order to make the statements in such Hyperion SEC Reports, in the light of the circumstances under which they were made, not misleading. None of Hyperion's Subsidiaries is required to file any forms, reports or other documents with the SEC. (b) Each of the consolidated financial statements (including, in each case, any related notes) contained in the Hyperion SEC Reports complied as to form in all material respects with the applicable published rules and regulations of the SEC with respect thereto, was prepared in accordance with GAAP applied on a consistent basis throughout the periods involved (except as may be indicated in the notes to such financial statements or, in the case of unaudited statements, as permitted by Form 10-Q of the SEC) and fairly presented the consolidated financial position of Hyperion and its Subsidiaries as of the dates and the consolidated results of its operations and cash flows for the periods indicated, except that the unaudited interim - 24 - 33 financial statements were or are subject to normal and recurring year-end adjustments which were not or are not expected to be material in amount. The audited balance sheet of Hyperion as of June 30, 1997 is referred to herein as the "Hyperion Balance Sheet." Section 4.05 NO UNDISCLOSED LIABILITIES. Except as disclosed in the Hyperion SEC Reports filed prior to the date hereof, and except for normal or recurring liabilities incurred since June 30, 1997 in the ordinary course of business consistent with past practices, Hyperion and its Subsidiaries do not have any liabilities, either accrued, contingent or otherwise (whether or not required to be reflected in financial statements in accordance with GAAP), and whether due or to become due, which individually or in the aggregate, are reasonably likely to have a Hyperion Material Adverse Effect. Section 4.06 ABSENCE OF CERTAIN CHANGES OR EVENTS. Except as disclosed in the Hyperion SEC Reports filed prior to the date hereof, during the period commencing on the date of the Hyperion Balance Sheet and ending on the date of this Agreement, Hyperion and its Subsidiaries have conducted their businesses only in the ordinary course and in a manner consistent with past practice and, during such period, there has not been (i) any change in the financial condition, results of operations, business or properties of Hyperion and its Subsidiaries, taken as a whole, which has had or could reasonably be expected to have a Hyperion Material Adverse Effect; (ii) any damage, destruction or loss (whether or not covered by insurance) with respect to Hyperion or any of its Subsidiaries having a Hyperion Material Adverse Effect; (iii) any material change by Hyperion in its accounting methods, principles or practices to which Arbor has not previously consented in writing; (iv) any revaluation by Hyperion of any of its assets having a Hyperion Material Adverse Effect; or (v) any other action or event that would have required the consent of Arbor pursuant to Section 5.01 of this Agreement had such action or event occurred after the date of this Agreement and that, in the case of this clause (v), individually or in the aggregate, has had or is reasonably likely to have a Hyperion Material Adverse Effect. Section 4.07 TAXES. (a) Each of Hyperion and its Subsidiaries has filed all Tax Returns that it was required to file, and, except to the extent that a reserve for Taxes was reflected on the Hyperion Balance Sheet (exclusive of any accruals for "deferred taxes" or similar items that reflect timing differences between Tax and financial accounting principles), all such Tax Returns were correct and complete. Each group of corporations with which Hyperion or any Subsidiary has filed (or was required to file) consolidated, combined, unitary or similar Tax Returns (a "Hyperion Affiliated Group") has filed all such Tax Returns that it was required to file with respect to any period in which Hyperion or a Subsidiary was a member of such Hyperion Affiliated Group (a "Hyperion Affiliated Period"), and, except to the extent that a reserve for - 25 - 34 Taxes was reflected on the Hyperion Balance Sheet (exclusive of any accruals for "deferred taxes" or similar items that reflect timing differences between Tax and financial accounting principles), all such Tax Returns were correct and complete. Except to the extent that a reserve for Taxes was reflected on the Hyperion Balance Sheet (exclusive of any accruals for "deferred taxes" or similar items that reflect timing differences between Tax and financial accounting principles), each of Hyperion and its Subsidiaries has paid all Taxes (whether or not shown on such Tax Returns) that were due and payable, and each Hyperion Affiliated Group has paid all Taxes (whether or not shown on such Tax Returns) that were due and payable with respect to all Hyperion Affiliated Periods and with respect to which Hyperion or any of its Subsidiaries may be liable by operation of law or otherwise. The unpaid Taxes of Hyperion and the Subsidiaries for Tax periods through the date of the Hyperion Balance Sheet do not exceed the accruals and reserves for Taxes set forth on the Hyperion Balance Sheet (exclusive of any accruals for "deferred taxes" or similar items that reflect timing differences between Tax and financial accounting principles). The unpaid Taxes of Hyperion and the Subsidiaries for Tax periods from the date of the Hyperion Balance Sheet through the Closing Date are attributable solely to the conduct of their businesses in the ordinary course and in a manner consistence with past practices. All Taxes that Hyperion or any Subsidiary is or was required by law to withhold or collect have been duly withheld or collected and, to the extent required, have been paid to the proper Governmental Entity. Each of the representations contained in this Section 4.07(a) shall be limited in its application to items which are reasonably likely, individually or in the aggregate, to have a Hyperion Material Adverse Effect. (b) Hyperion is not and never has been a party to or bound by any Tax indemnity, Tax sharing or Tax allocation agreement (whether written or unwritten or arising under operation of federal law as a result of being a member of a group filing consolidated Tax Returns, under operation of certain state laws as a result of being a member of a unitary group, or under comparable laws of other states or foreign jurisdictions) which includes a party other than Hyperion nor does Hyperion owe any amount under any such agreement. No examination or audit by any Governmental Entity of any Tax Return of Hyperion, any of its Subsidiaries or any Hyperion Affiliated Group with respect to a Hyperion Affiliated Period is currently in progress or, to the knowledge of Hyperion and its Subsidiaries, threatened or contemplated, in each case, which involve claims that individually or in the aggregate are reasonably likely to have a Hyperion Material Adverse Effect. Neither Hyperion nor any of its Subsidiaries has been informed by any jurisdiction that the jurisdiction believes that Hyperion or any of its Subsidiaries was required to file any Tax Return that was not filed which failure or failures individually, or in the aggregate, are reasonably likely to have a Hyperion Material Adverse Effect. (c) Neither Hyperion nor any of its Subsidiaries is a "consenting corporation" within the meaning of Section 341(f) of the Code, and none of the assets - 26 - 35 of Hyperion or the Subsidiaries are subject to an election under Section 341(f) of the Code. (d) Neither Hyperion nor any of its Subsidiaries has been a United States real property holding corporation within the meaning of Section 897(c)(2) of the Code during the applicable period specified in Section 897(c)(l)(A)(ii) of the Code. (e) Neither Hyperion nor any of its Subsidiaries has made any payments, is obligated to make any payments, or is a party to any agreement that could obligate it to make any payments that will be an "excess parachute payment" under Code Section 280G. Section 4.08 PROPERTIES. (a) Hyperion has provided to Arbor a true and complete list of all real property that Hyperion or any of its Subsidiaries owns. With respect to each such item of real property, except as disclosed in the Hyperion SEC Reports and except for such matters that, individually or in the aggregate, are not reasonably likely to have a Hyperion Material Adverse Effect: (a) Hyperion or the identified Subsidiary has good and clear record and marketable title to such property, insurable by a recognized national title insurance company at standard rates, free and clear of any security interest, easement, covenant or other restriction, except for recorded easements, covenants and other restrictions which do not materially impair the current uses or occupancy of such property; and (b) the improvements constructed on such property are in good condition, and all mechanical and utility systems servicing such improvements are in good condition, free in each case of material defects. (b) All material real property leases of Hyperion and its Subsidiaries are in good standing, valid and effective in accordance with their respective terms, and neither Hyperion nor its Subsidiaries is in default under any of such leases, except where the lack of such good standing, validity or effectiveness or the existence of such default would not be reasonably likely to have a Hyperion Material Adverse Effect. Section 4.09 INTELLECTUAL PROPERTY. (a) Hyperion and its Subsidiaries own, or are licensed or otherwise possess legally enforceable rights to use, all patents, trademarks, trade names, service marks, copyrights and mask works, any applications for and registrations of such patents, trademarks, trade names, service marks, copyrights and mask works, and all processes, formulae, methods, schematics, technology, know-how, computer software programs or applications and tangible or intangible proprietary information or material that are necessary to conduct the business of Hyperion and its Subsidiaries as currently conducted, or planned to be conducted, the absence of which would be - 27 - 36 reasonably likely to have a Hyperion Material Adverse Effect (the "Hyperion Intellectual Property Rights"). (b) Neither Hyperion nor any of its Subsidiaries is, or will as a result of the execution and delivery of this Agreement or the performance of Hyperion's obligations under this Agreement or otherwise be, in breach of any license, sublicense or other agreement relating to the Hyperion Intellectual Property Rights, or any material licenses, sublicenses and other agreements as to which Hyperion or any of its Subsidiaries is a party and pursuant to which Hyperion or any of its Subsidiaries is authorized to use any third party patents, trademarks or copyrights ("Hyperion Third Party Intellectual Property Rights"), including software that is used in the manufacture of, incorporated in, or forms a part of any product sold by or expected to be sold by Hyperion or any of its Subsidiaries, the breach of which would be reasonably likely to have a Hyperion Material Adverse Effect. (c) All patents, registered trademarks, service marks and copyrights which are held by Hyperion or any of its Subsidiaries and which are material to the business of Hyperion and its Subsidiaries, taken as a whole, are valid and subsisting. Hyperion (i) has not been sued in any suit, action or proceeding, or received in writing any claim or notice, which involves a claim of infringement of any patents, trademarks, service marks, copyrights or violation of any trade secret or other proprietary right of any third party; and (ii) has no knowledge that the manufacturing, marketing, licensing or sale of its products infringes any patent, trademark, service mark, copyright, trade secret or other proprietary right of any third party, which infringement would reasonably be expected to have a Hyperion Material Adverse Effect. Section 4.10 AGREEMENTS, CONTRACTS AND COMMITMENTS. Hyperion has not breached, or received in writing any claim or notice that it has breached, any of the terms or conditions of any agreement, contract or commitment filed as an exhibit to the Hyperion SEC Reports ("Hyperion Material Contracts") in such a manner as, individually or in the aggregate, are reasonably likely to have a Hyperion Material Adverse Effect. Each Hyperion Material Contract that has not expired by its terms is in full force and effect. Section 4.11 LITIGATION. Except as described in the Hyperion SEC Reports filed prior to the date hereof, there is no action, suit or proceeding, claim, arbitration or investigation against Hyperion or any of its Subsidiaries pending or as to which Hyperion or any such Subsidiary has received any written notice of assertion, which, individually or in the aggregate, is reasonably likely to have a Hyperion Material Adverse Effect or a material adverse effect on the ability of Hyperion to consummate the transactions contemplated by this Agreement. - 28 - 37 Section 4.12 ENVIRONMENTAL MATTERS. Except as disclosed in the Hyperion SEC Reports filed prior to the date hereof and except for such matters that, individually or in the aggregate, are not reasonably likely to have a Hyperion Material Adverse Effect: (i) Hyperion and its Subsidiaries have complied with all applicable Environmental Laws; (ii) the properties currently owned or operated by Hyperion and its Subsidiaries (including soils, groundwater, surface water, buildings or other structures) are not contaminated with any Hazardous Substances; (iii) the properties formerly owned or operated by Hyperion or any of its Subsidiaries were not contaminated with Hazardous Substances during the period of ownership or operation by Hyperion or any of its Subsidiaries; (iv) neither Hyperion nor any of its Subsidiaries are subject to liability for any Hazardous Substance disposal or contamination on any third party property; (v) neither Hyperion nor any of its Subsidiaries has been associated with any release or threat of release of any Hazardous Substance; (vi) neither Hyperion nor any of its Subsidiaries has received any notice, demand, letter, claim or request for information alleging that Hyperion or any of its Subsidiaries may be in violation of or liable under any Environmental Law; (vii) neither Hyperion nor any of its Subsidiaries is subject to any orders, decrees, injunctions or other arrangements with any Governmental Entity or is subject to any indemnity or other agreement with any third party relating to liability under any Environmental Law or relating to Hazardous Substances; and (viii) there are no circumstances or conditions involving Hyperion or any of its Subsidiaries that could reasonably be expected to result in any claims, liability, investigations, costs or restrictions on the ownership, use or transfer of any property of Hyperion pursuant to any Environmental Law.

(a) Hyperion has listed in Section 4.13 of the Hyperion Disclosure Schedule all employee benefit plans (as defined in Section 3(3) of ERISA) and all bonus, stock option, stock purchase, incentive, deferred compensation, supplemental retirement, severance and other similar employee benefit plans, and all unexpired severance agreements, written or otherwise, for the benefit of, or relating to, any current or former employee of Hyperion or any ERISA Affiliate of Hyperion, or any Subsidiary of Hyperion (collectively, the "Hyperion Employee Plans"). (b) With respect to each Hyperion Employee Plan, Hyperion has made available to Arbor, a true and correct copy of (i) the most recent annual report (Form 5500), if any, filed with the IRS, (ii) such Hyperion Employee Plan, (iii) each trust agreement and group annuity contract, if any, relating to such Hyperion Employee Plan and (iv) the most recent actuarial report or valuation relating to a Hyperion Employee Plan subject to Title IV of ERISA. (c) With respect to the Hyperion Employee Plans, individually and in the aggregate, no event has occurred and, to the knowledge of Hyperion, there exists no - 29 - 38 condition or set of circumstances in connection with which Hyperion could be subject to any liability that is reasonably likely to have a Hyperion Material Adverse Effect under ERISA, the Code or any other applicable law. (d) With respect to the Hyperion Employee Plans, individually and in the aggregate, there are no funded benefit obligations for which contributions have not been made or properly accrued and there are no unfunded benefit obligations that have not been accounted for by reserves, or otherwise properly footnoted in accordance with GAAP, on the financial statements of Hyperion, which obligations are reasonably likely to have a Hyperion Material Adverse Effect.

Hyperion Software Corporation By: /s/ James Perakis ------------------------------------ Title: Chairman and Chief Executive --------------------------------- Officer --------------------------------- HSC Merger Corp. By: /s/ John Dillon ------------------------------------ Title: President --------------------------------- Arbor Software Corporation By: /s/ John Dillon ------------------------------------ Title: President and Chief Executive --------------------------------- Officer --------------------------------- - 54 - 63 Exhibit A --------- Hyperion Stock Option Agreement STOCK OPTION AGREEMENT, dated as of May 25, 1998 (the "Agreement"), between HYPERION SOFTWARE CORPORATION, a Delaware corporation (the "Grantee"), and ARBOR SOFTWARE CORPORATION, a Delaware corporation (the "Grantor"). WHEREAS, the Grantee, the Grantor and HSC Merger Corp., a Delaware corporation and a wholly owned subsidiary of the Grantor ("Sub"), are entering into an Agreement and Plan of Merger, dated as of the date hereof (the "Merger Agreement"), which provides, among other things, for the merger (the "Merger") of Sub with and into the Grantee; WHEREAS, as a condition to its willingness to enter into the Merger Agreement, the Grantee has requested that the Grantor grant to the Grantee an option to purchase 2,274,000 shares of Common Stock, par value $0.001 per share, of the Grantor (the "Common Stock"), upon the terms and subject to the conditions hereof; and WHEREAS, in order to induce the Grantee to enter into the Merger Agreement, the Grantor is willing to grant the Grantee the requested option. NOW, THEREFORE, in consideration of the premises and the mutual covenants and agreements set forth herein, the parties hereto agree as follows: 1. THE OPTION; EXERCISE; ADJUSTMENTS; PAYMENT OF SPREAD. (a) Contemporaneously herewith the Grantee, Sub and the Grantor are entering into the Merger Agreement. Subject to the other terms and conditions set forth herein, the Grantor hereby grants to the Grantee an irrevocable option (the "Option") to purchase up to 2,274,000 shares of Common Stock (the "Shares") at a cash purchase price equal to the lowest of (i) $42.125 per Share, (ii) the average closing price of the Common Stock on the Nasdaq National Market for the five consecutive trading days beginning on and including the day that the Merger is publicly announced, or (iii) the average closing price of the Common Stock on the Nasdaq National Market for the five consecutive trading days immediately preceding the public announcement of an Alternative Transaction (as defined in the Merger Agreement) involving Grantor giving rise to the right to exercise this Option pursuant to Section 2 below (the "Purchase Price"). The Option may be exercised by the Grantee, in whole or in part, at any time, or from time to time, following the A-1 64 occurrence of one of the events set forth in Section 2(c) hereof and prior to the termination of the Option in accordance with the terms of this Agreement. (b) In the event the Grantee wishes to exercise the Option, the Grantee shall send a written notice to the Grantor (the "Stock Exercise Notice") specifying a date (subject to the HSR Act (as defined below)) not later than 10 business days and not earlier than the next business day following the date such notice is given for the closing of such purchase. In the event of any change in the number of issued and outstanding shares of Common Stock by reason of any stock dividend, stock split, split-up, recapitalization, merger or other change in the corporate or capital structure of the Grantor, the number of Shares subject to this Option and the purchase price per Share shall be appropriately adjusted to restore to the Grantee its rights hereunder, including its right to purchase Shares representing 19.9% of the capital stock of the Grantor entitled to vote generally for the election of the directors of the Grantor which is issued and outstanding immediately prior to the exercise of the Option at an aggregate purchase price equal to the Purchase Price multiplied by 2,274,000. (c) If at any time the Option is then exercisable pursuant to the terms of Section 1(a) hereof, the Grantee may elect, in lieu of exercising the Option to purchase Shares provided in Section 1.(a) hereof, to send a written notice to the Grantor (the "Cash Exercise Notice") specifying a date not later than 20 business days and not earlier than 10 business days following the date such notice is given on which date the Grantor shall pay to the Grantee an amount in cash equal to the Spread (as hereinafter defined) multiplied by all or such portion of the Shares subject to the Option as Grantee shall specify. As used herein "Spread" shall mean the excess, if any, over the Purchase Price of the higher of (x) if applicable, the highest price per share of Common Stock (including any brokerage commissions, transfer taxes and soliciting dealers' fees) paid by any person in an Alternative Transaction (as defined in the Merger Agreement) (the "Alternative Purchase Price") or (y) the closing price of the shares of Common Stock on the Nasdaq National Market on the last trading day immediately prior to the date of the Cash Exercise Notice (the "Closing Price"). If the Alternative Purchase Price includes any property other than cash, the Alternative Purchase Price shall be the sum of (i) the fixed cash amount, if any, included in the Alternative Purchase Price plus (ii) the fair market value of such other property. If such other property consists of securities with an existing public trading market, the average of the closing prices (or the average of the closing bid and asked prices if closing prices are unavailable) for such securities in their principal public trading market on the five trading days ending five days prior to the date of the Cash Exercise Notice shall be deemed to equal the fair market value of such property. If such other property consists of something other than cash or securities with an existing public trading market and, as of the payment date for the Spread, agreement on the value of such other property has not been reached, the Alternative Purchase Price shall be deemed to equal the Closing Price. Upon exercise of its right to receive cash pursuant to this Section 1(c), the obligations of the Grantor to deliver Shares pursuant to A-2 65 Section 3 shall be terminated with respect to such number of Shares for which the Grantee shall have elected to be paid the Spread. 2. CONDITIONS TO DELIVERY OF SHARES. The Grantor's obligation to deliver Shares upon exercise of the Option or the Spread upon exercise of the Grantor's rights under Section 1(c) above is subject only to the conditions that: (a) No preliminary or permanent injunction or other order issued by any federal or state court of competent jurisdiction in the United States prohibiting the delivery of the Shares shall be in effect; and (b) Any applicable waiting periods under the Hart-Scott-Rodino Antitrust Improvements Act of 1976 (the "HSR Act") shall have expired or been terminated; and (c) A proposal for an Alternative Transaction involving Grantor shall have been made prior to the date the Merger Agreement is terminated pursuant to the terms thereof (the "Merger Termination Date") and one or more of the following events shall have occurred on or after the date of the making of such proposal: (1) the requisite vote of the stockholders of Grantor in favor of the Arbor Voting Proposals shall not have been obtained at the Arbor Stockholders' Meeting (as such terms are defined in the Merger Agreement) or any adjournment or postponement thereof; (2) the Board of Directors of Grantor shall have withdrawn or modified its recommendation of the Merger Agreement or the Merger; (3) the Board of Directors of Grantor shall have recommended to the stockholders of Grantor an Alternative Transaction (as defined in the Merger Agreement); (4) a tender offer or exchange offer for 15% or more of the outstanding shares of Grantor Common Stock shall have been commenced (other than by Grantee or an affiliate of Grantee) and the Board of Directors of Grantor shall have recommended that the stockholders of Grantor tender their shares in such tender or exchange offer; or (5) for any reason Grantor shall have failed to call and hold the Arbor Stockholders' Meeting (as defined in the Merger Agreement) by the Outside Date (as defined in the Merger Agreement) and Grantor is not at such time otherwise entitled to terminate the Merger Agreement pursuant to Section 8.01(g) thereof. 3.

For so long as, and at any time that, a designee of the Grantee is a member of the Board of Directors of the Grantor, the Grantee covenants and agrees that the Grantee will not enter into any agreement or understanding with any person with respect to the voting of any shares of Common Stock it may beneficially own, and shall vote all such shares beneficially owned by it (unless the aggregate of all such shares of Common Stock beneficially owned by the Grantee and its affiliates exceeds 50% of the outstanding shares of Common Stock) in favor of the Grantor's nominees for election of directors. 8. RIGHT OF FIRST REFUSAL. If a Change in Control Event (as defined in Section 8(e) below) has not then already occurred, if the Grantee, at any time prior to the first anniversary of the Merger Termination Date, seeks to sell all or any part of the Shares (i) in a transaction registered under the Securities Act (other than in a registered public offering in which the underwriters are instructed to achieve a broad public distribution) or (ii) in a transaction not required to be registered under the Securities Act (other than in a transfer by operation of law upon consummation of a merger), it shall give the Grantor (or a designee of the Grantor) the opportunity, in the following manner, to purchase such Shares: (a) The Grantee shall give notice to the Grantor in writing of its intent to sell Shares (a "Disposition Notice"), specifying the number of Shares to be sold, the price and, if applicable, the material terms of any agreement relating thereto For purposes of this Section 8, if the Disposition Notice is given with respect to the sale of the Shares pursuant to a tender or exchange offer, it shall be assumed that all Shares tendered will be accepted for payment. The Disposition Notice may be given at any time, including prior to the giving of any Stock Exercise Notice. (b) The Grantor or its designee shall have the right, exercisable by written notice given to the Grantee within five business days after receipt of a Disposition Notice (or, if applicable, in the case of a proposed sale pursuant to a tender or exchange offer for shares of Common Stock, by written notice given to the Grantee at least two business days prior to the then announced expiration date of such tender or exchange offer (the "Expiration Date") if such Disposition Notice was given at least four business days prior to such Expiration Date), to purchase all, but not less than all, of the Shares specified in the Disposition Notice at the price set forth in the Disposition Notice. If the purchase price specified in the Disposition Notice includes any property other than cash, the purchase price to be paid by the Grantor shall be an amount of cash equal to the sum of (i) the cash included in the purchase price plus (ii) the fair market value of such other property at the date of the Disposition Notice. If such other property consists of securities with an existing public trading market, the A-6 69 average of the last sales prices for such securities on the five trading days ending five days prior to the date of the Disposition Notice shall be used as the fair market value of such property. If such other property consists of something other than cash or securities with an existing public trading market and at the time of the closing referred to in paragraph (c) below, agreement on the value of such other property has not been reached, the average of the closing prices for the Grantor's Common Stock on the five trading days ending five days prior to the date of the Disposition Notice shall be used as the per share purchase price; provided, however, that promptly after the closing, the Grantee and the Grantor or its designee, as the case may be, shall settle any additional amounts to be paid or returned as a result of the determination of fair market value of such other property made by a nationally recognized investment banking firm selected by the Grantor and approved by the Grantee within 30 days of the closing. Such determination shall be final and binding on all parties hereto. If, at the time of the purchase of any Shares by the Grantor (or its designee) pursuant to this Section 8, a tender or exchange offer is outstanding, then the Grantor (or its designee) shall agree at the time of such purchase to promptly pay to Grantee from time to time such additional amounts, if any, so that the consideration received by Grantee with respect to each Share shall be equal to the highest price paid for a share of Common Stock pursuant to such tender or exchange, or pursuant to any other tender or exchange offer outstanding at any time such tender or exchange offer is outstanding. (c) If the Grantor exercises its right of first refusal hereunder, the closing of the purchase of the Shares with respect to which such right has been exercised shall take place within five business days after the notice of such exercise (or, if applicable, in the case of a tender or exchange offer, no later than one business day prior to the expiration date of the offer if written notice was given within the time set forth in the parenthetical in the first sentence of paragraph (b) above); provided, however, that at any time prior to the closing of the purchase of Shares hereunder, the Grantee may determine not to sell the Shares and revoke the Disposition Notice and by so doing, cancel the Grantor's right of first refusal with respect to the disposition in question. The Grantor (or its designee) shall pay for the Shares in immediately available funds. (d) If the Grantor does not exercise its right of first refusal hereunder within the time specified for such exercise, the Grantee shall be free for 90 days following the expiration of such time for exercise to sell or enter into an agreement to sell the Shares specified in the Disposition Notice, at the price specified in the Disposition Notice or any price in excess thereof and otherwise on substantially the same terms set forth in the Disposition Notice; provided, that if such sale is not consummated within such 90-day period, then the provisions of this Section 8 will again apply to the sale of such Shares. A-7 70 (e) For purposes of the Agreement, a "Change in Control Event" shall be deemed to have occurred if (i) any person has a acquired beneficial ownership of more than 50% (excluding the Shares) of the outstanding shares of Common Stock or (ii) the Grantor shall have entered into an agreement, including without limitation an agreement in principle, providing for a merger or other business combination involving the Grantor or the acquisition of 20% or more of the assets of the Grantor and its subsidiaries, taken as a whole. 9. REPURCHASE OF SHARES; SALE OF SHARES. (a) If a Change in Control Event has not occurred prior to the first anniversary date of the Merger Termination Date, then beginning on such anniversary date, the Grantor shall have the right to purchase (the "Repurchase Right") all, but not less than all, of the Shares at the greater of (i) the Purchase Price, or (ii) the average of the closing prices for shares of Common Stock on the five trading days ending five days prior to the date the Grantor gives written notice of its intention to exercise the Repurchase Right. If the Grantor does not exercise the Repurchase Right within 30 days following the first anniversary of the Merger Termination Date, the Repurchase Right shall terminate. In the event the Grantor wishes to exercise the Repurchase Right, the Grantor shall send a written notice to the Grantee specifying a date (not later than 10 business days and not earlier than the next business day following the date such notice is given) for the closing of such purchase. (b) At any time prior to the first anniversary of the Merger Termination Date, the Grantee shall have the right to sell (the "Sale Right") to the Grantor all, but no less than all, of the Shares at the greater of (i) the Purchase Price or (ii) the average of the last sales prices for shares of Common Stock on the five trading days ending five days prior to the date the Grantee gives written notice of its intention to exercise the Sale Right. If the Grantee does not exercise the Sale Right prior to the first anniversary of the Merger Termination Date, the Sale Right shall terminate.

(a) In the event that the Grantee shall desire to sell any of the Shares within two years after the purchase of such Shares pursuant hereto, and such sale requires, in the opinion of counsel to the Grantee, which opinion shall be reasonably satisfactory to the Grantor and its counsel, registration of such Shares under the Securities Act, the Grantor will cooperate with the Grantee and any underwriters in registering such Shares for resale, including, without limitation, promptly filing a registration statement that complies with the requirements of applicable federal and A-8 71 state securities laws and entering into an underwriting agreement with such underwriters upon such terms and conditions as are customarily contained in underwriting agreements with respect to secondary distributions; provided that the Grantor shall not be required to have declared effective more than two registration statements hereunder and shall be entitled to delay the filing or effectiveness of any registration statement for up to 120 days if the offering would, in the judgment of the Board of Directors of the Grantor, require premature disclosure of any material corporate development or otherwise interfere with or adversely affect any pending or proposed offering of securities of the Grantor or any other material transaction involving the Grantor. (b) If the Common Stock is registered pursuant to the provisions of this Section 10, the Grantor agrees (i) to furnish copies of the registration statement and the prospectus relating to the Shares covered thereby in such numbers as the Grantee may from time to time reasonably request and (ii) if any event shall occur as a result of which it becomes necessary to amend or supplement any registration statement or prospectus, to prepare and file under the applicable securities laws such amendments and supplements as may be necessary to keep available for at least 90 days a prospectus covering the Common Stock meeting the requirements of such securities laws, and to furnish the Grantee such numbers of copies of the registration statement and prospectus as amended or supplemented as may reasonably be requested. The Grantor shall bear the cost of the registration, including, but not limited to, all registration and filing fees, printing expenses, and fees and disbursements of counsel and accountants for the Grantor, except that the Grantee shall pay the fees and disbursements of its counsel, the underwriting fees and selling commissions applicable to the shares of Common Stock sold by the Grantee. The Grantor shall indemnify and hold harmless Grantee, its affiliates and its officers and directors from and against any and all losses, claims, damages, liabilities and expenses arising out of or based upon any statements contained in, omissions or alleged omissions from, each registration statement filed pursuant to this paragraph; provided, however, that this provision does not apply to any loss, liability, claim, damage or expense to the extent it arises out of any untrue statement or omission made in reliance upon and in conformity with written information furnished to the Grantor by the Grantee, its affiliates and its officers expressly for use in any registration statement (or any amendment thereto) or any preliminary prospectus filed pursuant to this paragraph. The Grantor shall also indemnify and hold harmless each underwriter and each person who controls any underwriter within the meaning of either the Securities Act or the Securities Exchange Act of 1934 against any and all losses, claims, damages, liabilities and expenses arising out of or based upon any statements contained in, omissions or alleged omissions from, each registration statement filed pursuant to this paragraph; provided, however, that this provision does not apply to any loss, liability, claim, damage or expense to the extent it arises out of any untrue statement or omission made in reliance upon and in conformity with written information furnished to the Grantor by the underwriters expressly for use in any registration statement (or A-9 72 any amendment thereto) or any preliminary prospectus filed pursuant to this paragraph. 11. PROFIT LIMITATION. (a) Notwithstanding any other provision of this Agreement, in no event shall the Grantee's Total Profit (as defined in Section 11(c) below) exceed $30 million and, if it otherwise would exceed such amount, the Grantee, at its sole election, shall either (i) deliver to the Grantor for cancellation Shares previously purchased by Grantee, (ii) pay cash or other consideration to the Grantor or (iii) undertake any combination thereof, so that Grantee's Total Profit shall not exceed $30 million after taking into account the foregoing actions. (b) Notwithstanding any other provision of this Agreement, this Option may not be exercised for a number of Shares as would, as of the date of the Stock Exercise Notice, result in a Notional Total Profit (as defined in Section 11(c) below) of more than $30 million and, if exercise of the Option otherwise would exceed such amount, the Grantee, at its discretion, may increase the Purchase Price for that number of Shares set forth in the Stock Exercise Notice so that the Notional Total Profit shall not exceed $30 million; provided, that nothing in this sentence shall restrict any exercise of the Option permitted hereby on any subsequent date at the Purchase Price set forth in Section 1(a) hereof. (c) As used herein, the term "Total Profit" shall mean the aggregate amount (before taxes) of the following: (i) the amount of cash received by Grantee pursuant to Section 8.03(c) of the Merger Agreement and Section 1(c) hereof, (ii) (x) the amount received by Grantee pursuant to the Grantor's repurchase of Shares pursuant to Sections 8 or 9 hereof, less (y) the Grantee's purchase price for such Shares, and (iii) (x) the net cash amounts received by Grantee pursuant to the sale of Shares (or any other securities into which such Shares are converted or exchanged) to any unaffiliated party, less (y) the Grantee's purchase price for such Shares. (d) As used herein, the term "Notional Total Profit" with respect to any number of Shares as to which Grantee may propose to exercise this Option shall be the Total Profit determined as of the date of the Stock Exercise Notice assuming that this Option were exercised on such date for such number of Shares and assuming that such Shares, together with all other Shares held by Grantee and its affiliates as of such date, were sold for cash at the closing market price for the Common Stock as of the close of business on the preceding trading day (less customary brokerage commissions). 12.

In such event, the Grantor agrees that the Grantee shall have the right, in addition to any other rights it may have, to specific performance of this Agreement. Accordingly, if the Grantee should institute an action or proceeding seeking specific enforcement of the provisions hereof, the Grantor hereby waives the claim or defense that the Grantee has an adequate remedy at law and hereby agrees not to assert in any such action or proceeding the claim or defense that such a remedy at law exists.

Hyperion Software Corporation By: /s/ James Perakis ---------------------------------------- Title: Chairman and Chief Executive Officer -------------------------------------- Arbor Software Corporation By: /s/ John Dillon ---------------------------------------- Title: President and Chief Executive Officer -------------------------------------- A-14 77 Exhibit B --------- Arbor Stock Option Agreement STOCK OPTION AGREEMENT, dated as of May 25, 1998 (the "Agreement"), between ARBOR SOFTWARE CORPORATION, a Delaware corporation (the "Grantee"), and HYPERION SOFTWARE CORPORATION, a Delaware corporation (the "Grantor"). WHEREAS, the Grantee, the Grantor and HSC Merger Corp., a Delaware corporation and a wholly owned subsidiary of the Grantee ("Sub"), are entering into an Agreement and Plan of Merger, dated as of the date hereof (the "Merger Agreement"), which provides, among other things, for the merger (the "Merger") of Sub with and into the Grantor; WHEREAS, as a condition to its willingness to enter into the Merger Agreement, the Grantee has requested that the Grantor grant to the Grantee an option to purchase 3,789,000 shares of Common Stock, par value $0.01 per share, of the Grantor (the "Common Stock"), upon the terms and subject to the conditions hereof; and WHEREAS, in order to induce the Grantee to enter into the Merger Agreement, the Grantor is willing to grant the Grantee the requested option. NOW, THEREFORE, in consideration of the premises and the mutual covenants and agreements set forth herein, the parties hereto agree as follows: 1. THE OPTION; EXERCISE; ADJUSTMENTS; PAYMENT OF SPREAD. (a) Contemporaneously herewith the Grantee, Sub and the Grantor are entering into the Merger Agreement. Subject to the other terms and conditions set forth herein, the Grantor hereby grants to the Grantee an irrevocable option (the "Option") to purchase up to 3,789,000 shares of Common Stock (the "Shares") at a cash purchase price equal to the lowest of (i) $38.125 per Share, (ii) the average closing price of the Common Stock on the Nasdaq National Market for the five consecutive trading days beginning on and including the day that the Merger is publicly announced, or (iii) the average closing price of the Common Stock on the Nasdaq National Market for the five consecutive trading days immediately preceding the public announcement of an Alternative Transaction (as defined in the Merger Agreement) involving Grantor giving rise to the right to exercise this Option pursuant to Section 2 below (the "Purchase Price"). The Option may be exercised by the Grantee, in whole or in part, at any time, or from time to time, following the occurrence of one of the events set forth B-1 78 in Section 2(c) hereof and prior to the termination of the Option in accordance with the terms of this Agreement. (b) In the event the Grantee wishes to exercise the Option, the Grantee shall send a written notice to the Grantor (the "Stock Exercise Notice") specifying a date (subject to the HSR Act (as defined below)) not later than 10 business days and not earlier than the next business day following the date such notice is given for the closing of such purchase. In the event of any change in the number of issued and outstanding shares of Common Stock by reason of any stock dividend, stock split, split-up, recapitalization, merger or other change in the corporate or capital structure of the Grantor, the number of Shares subject to this Option and the purchase price per Share shall be appropriately adjusted to restore to the Grantee its rights hereunder, including its right to purchase Shares representing 19.9% of the capital stock of the Grantor entitled to vote generally for the election of the directors of the Grantor which is issued and outstanding immediately prior to the exercise of the Option at an aggregate purchase price equal to the Purchase Price multiplied by 3,789,000. (c) If at any time the Option is then exercisable pursuant to the terms of Section 1(a) hereof, the Grantee may elect, in lieu of exercising the Option to purchase Shares provided in Section 1.(a) hereof, to send a written notice to the Grantor (the "Cash Exercise Notice") specifying a date not later than 20 business days and not earlier than 10 business days following the date such notice is given on which date the Grantor shall pay to the Grantee an amount in cash equal to the Spread (as hereinafter defined) multiplied by all or such portion of the Shares subject to the Option as Grantee shall specify. As used herein "Spread" shall mean the excess, if any, over the Purchase Price of the higher of (x) if applicable, the highest price per share of Common Stock (including any brokerage commissions, transfer taxes and soliciting dealers' fees) paid by any person in an Alternative Transaction (as defined in the Merger Agreement) (the "Alternative Purchase Price") or (y) the closing price of the shares of Common Stock on the Nasdaq National Market on the last trading day immediately prior to the date of the Cash Exercise Notice (the "Closing Price"). If the Alternative Purchase Price includes any property other than cash, the Alternative Purchase Price shall be the sum of (i) the fixed cash amount, if any, included in the Alternative Purchase Price plus (ii) the fair market value of such other property. If such other property consists of securities with an existing public trading market, the average of the closing prices (or the average of the closing bid and asked prices if closing prices are unavailable) for such securities in their principal public trading market on the five trading days ending five days prior to the date of the Cash Exercise Notice shall be deemed to equal the fair market value of such property. If such other property consists of something other than cash or securities with an existing public trading market and, as of the payment date for the Spread, agreement on the value of such other property has not been reached, the Alternative Purchase Price shall be deemed to equal the Closing Price. Upon exercise of its right to receive cash pursuant to this Section 1(c), the obligations of the Grantor to deliver Shares pursuant to B-2 79 Section 3 shall be terminated with respect to such number of Shares for which the Grantee shall have elected to be paid the Spread. 2. CONDITIONS TO DELIVERY OF SHARES. The Grantor's obligation to deliver Shares upon exercise of the Option or the Spread upon exercise of the Grantor's rights under Section 1(c) above is subject only to the conditions that: (a) No preliminary or permanent injunction or other order issued by any federal or state court of competent jurisdiction in the United States prohibiting the delivery of the Shares shall be in effect; and (b) Any applicable waiting periods under the Hart-Scott-Rodino Antitrust Improvements Act of 1976 (the "HSR Act") shall have expired or been terminated; and (c) A proposal for an Alternative Transaction involving Grantor shall have been made prior to the date the Merger Agreement is terminated pursuant to the terms thereof (the "Merger Termination Date") and one or more of the following events shall have occurred on or after the date of the making of such proposal: (1) the requisite vote of the stockholders of Grantor in favor of the Merger Agreement and the Merger shall not have been obtained at the Hyperion Stockholders' Meeting (as such term is defined in the Merger Agreement) or any adjournment or postponement thereof; (2) the Board of Directors of Grantor shall have withdrawn or modified its recommendation of the Merger Agreement or the Merger; (3) the Board of Directors of Grantor shall have recommended to the stockholders of Grantor an Alternative Transaction (as defined in the Merger Agreement); (4) a tender offer or exchange offer for 15% or more of the outstanding shares of Grantor Common Stock shall have been commenced (other than by Grantee or an affiliate of Grantee) and the Board of Directors of Grantor shall have recommended that the stockholders of Grantor tender their shares in such tender or exchange offer; or (5) for any reason Grantor shall have failed to call and hold the Hyperion Stockholders' Meeting (as defined in the Merger Agreement) by the Outside Date (as defined in the Merger Agreement) and Grantor is not at such time otherwise entitled to terminate the Merger Agreement pursuant to Section 8.01(g) thereof. 3.

Notwithstanding the foregoing, the Grantor shall not be required to nominate the designee of the Grantee, and shall be entitled to request and receive the resignation of any designee of the Grantee then serving on the Board of Directors of the Grantor, at any time that the Grantee then beneficially owns less than 1,900,000 shares of Common Stock. The Grantee and the Grantor agree to take such steps as may be necessary to give effect to this Section 6(b) in a manner consistent with applicable law. 7. COVENANTS OF THE GRANTEE. For so long as, and at any time that, a designee of the Grantee is a member of the Board of Directors of the Grantor, the Grantee covenants and agrees that the Grantee will not enter into any agreement or understanding with any person with respect to the voting of any shares of Common Stock it may beneficially own, and shall vote all such shares beneficially owned by it (unless the aggregate of all such shares of Common Stock beneficially owned by the Grantee and its affiliates exceeds 50% of the outstanding shares of Common Stock) in favor of the Grantor's nominees for election of directors. 8. RIGHT OF FIRST REFUSAL. If a Change in Control Event (as defined in Section 8(e) below) has not then already occurred, if the Grantee, at any time prior to the first anniversary of the Merger Termination Date, seeks to sell all or any part of the Shares (i) in a transaction registered under the Securities Act (other than in a registered public offering in which the underwriters are instructed to achieve a broad public distribution) or (ii) in a transaction not required to be registered under the Securities Act (other than in a transfer by operation of law upon consummation of a merger), it shall give the Grantor (or a designee of the Grantor) the opportunity, in the following manner, to purchase such Shares: (a) The Grantee shall give notice to the Grantor in writing of its intent to sell Shares (a "Disposition Notice"), specifying the number of Shares to be sold, the price and, if applicable, the material terms of any agreement relating thereto For purposes of this Section 8, if the Disposition Notice is given with respect to the sale of the Shares pursuant to a tender or exchange offer, it shall be assumed that all Shares tendered will be accepted for payment. The Disposition Notice may be given at any time, including prior to the giving of any Stock Exercise Notice. (b) The Grantor or its designee shall have the right, exercisable by written notice given to the Grantee within five business days after receipt of a Disposition Notice (or, if applicable, in the case of a proposed sale pursuant to a tender or exchange offer for shares of Common Stock, by written notice given to the Grantee at least two business days prior to the then announced expiration date of such tender or exchange offer (the "Expiration Date") if such Disposition Notice was given at least four business days prior to such Expiration Date), to purchase all, but not less than all, of the Shares specified in the Disposition Notice at the price set forth in the Disposition Notice. If the purchase price specified in the Disposition Notice includes B-6 83 any property other than cash, the purchase price to be paid by the Grantor shall be an amount of cash equal to the sum of (i) the cash included in the purchase price plus (ii) the fair market value of such other property at the date of the Disposition Notice. If such other property consists of securities with an existing public trading market, the average of the last sales prices for such securities on the five trading days ending five days prior to the date of the Disposition Notice shall be used as the fair market value of such property. If such other property consists of something other than cash or securities with an existing public trading market and at the time of the closing referred to in paragraph (c) below, agreement on the value of such other property has not been reached, the average of the closing prices for the Grantor's Common Stock on the five trading days ending five days prior to the date of the Disposition Notice shall be used as the per share purchase price; provided, however, that promptly after the closing, the Grantee and the Grantor or its designee, as the case may be, shall settle any additional amounts to be paid or returned as a result of the determination of fair market value of such other property made by a nationally recognized investment banking firm selected by the Grantor and approved by the Grantee within 30 days of the closing. Such determination shall be final and binding on all parties hereto. If, at the time of the purchase of any Shares by the Grantor (or its designee) pursuant to this Section 8, a tender or exchange offer is outstanding, then the Grantor (or its designee) shall agree at the time of such purchase to promptly pay to Grantee from time to time such additional amounts, if any, so that the consideration received by Grantee with respect to each Share shall be equal to the highest price paid for a share of Common Stock pursuant to such tender or exchange, or pursuant to any other tender or exchange offer outstanding at any time such tender or exchange offer is outstanding. (c) If the Grantor exercises its right of first refusal hereunder, the closing of the purchase of the Shares with respect to which such right has been exercised shall take place within five business days after the notice of such exercise (or, if applicable, in the case of a tender or exchange offer, no later than one business day prior to the expiration date of the offer if written notice was given within the time set forth in the parenthetical in the first sentence of paragraph (b) above); provided, however, that at any time prior to the closing of the purchase of Shares hereunder, the Grantee may determine not to sell the Shares and revoke the Disposition Notice and by so doing, cancel the Grantor's right of first refusal with respect to the disposition in question. The Grantor (or its designee) shall pay for the Shares in immediately available funds. (d) If the Grantor does not exercise its right of first refusal hereunder within the time specified for such exercise, the Grantee shall be free for 90 days following the expiration of such time for exercise to sell or enter into an agreement to sell the Shares specified in the Disposition Notice, at the price specified in the Disposition Notice or any price in excess thereof and otherwise on substantially the same terms set forth in the Disposition Notice; provided, that if such sale is not B-7 84 consummated within such 90-day period, then the provisions of this Section 8 will again apply to the sale of such Shares. (e) For purposes of the Agreement, a "Change in Control Event" shall be deemed to have occurred if (i) any person has a acquired beneficial ownership of more than 50% (excluding the Shares) of the outstanding shares of Common Stock or (ii) the Grantor shall have entered into an agreement, including without limitation an agreement in principle, providing for a merger or other business combination involving the Grantor or the acquisition of 20% or more of the assets of the Grantor and its subsidiaries, taken as a whole. 9. REPURCHASE OF SHARES; SALE OF SHARES. (a) If a Change in Control Event has not occurred prior to the first anniversary date of the Merger Termination Date, then beginning on such anniversary date, the Grantor shall have the right to purchase (the "Repurchase Right") all, but not less than all, of the Shares at the greater of (i) the Purchase Price, or (ii) the average of the closing prices for shares of Common Stock on the five trading days ending five days prior to the date the Grantor gives written notice of its intention to exercise the Repurchase Right. If the Grantor does not exercise the Repurchase Right within 30 days following the first anniversary of the Merger Termination Date, the Repurchase Right shall terminate. In the event the Grantor wishes to exercise the Repurchase Right, the Grantor shall send a written notice to the Grantee specifying a date (not later than 10 business days and not earlier than the next business day following the date such notice is given) for the closing of such purchase. (b) At any time prior to the first anniversary of the Merger Termination Date, the Grantee shall have the right to sell (the "Sale Right") to the Grantor all, but no less than all, of the Shares at the greater of (i) the Purchase Price or (ii) the average of the last sales prices for shares of Common Stock on the five trading days ending five days prior to the date the Grantee gives written notice of its intention to exercise the Sale Right. If the Grantee does not exercise the Sale Right prior to the first anniversary of the Merger Termination Date, the Sale Right shall terminate. In the event the Grantee wishes to exercise the Sale Right, the Grantee shall send a written notice to the Grantor specifying a date (not later than 20 business days and not earlier than 10 business days following the date such notice is given) for the closing of such sale. 10. REGISTRATION RIGHTS. (a) In the event that the Grantee shall desire to sell any of the Shares within two years after the purchase of such Shares pursuant hereto, and such sale requires, in the opinion of counsel to the Grantee, which opinion shall be reasonably satisfactory to the Grantor and its counsel, registration of such Shares under the B-8 85 Securities Act, the Grantor will cooperate with the Grantee and any underwriters in registering such Shares for resale, including, without limitation, promptly filing a registration statement that complies with the requirements of applicable federal and state securities laws and entering into an underwriting agreement with such underwriters upon such terms and conditions as are customarily contained in underwriting agreements with respect to secondary distributions; provided that the Grantor shall not be required to have declared effective more than two registration statements hereunder and shall be entitled to delay the filing or effectiveness of any registration statement for up to 120 days if the offering would, in the judgment of the Board of Directors of the Grantor, require premature disclosure of any material corporate development or otherwise interfere with or adversely affect any pending or proposed offering of securities of the Grantor or any other material transaction involving the Grantor. (b) If the Common Stock is registered pursuant to the provisions of this Section 10, the Grantor agrees (i) to furnish copies of the registration statement and the prospectus relating to the Shares covered thereby in such numbers as the Grantee may from time to time reasonably request and (ii) if any event shall occur as a result of which it becomes necessary to amend or supplement any registration statement or prospectus, to prepare and file under the applicable securities laws such amendments and supplements as may be necessary to keep available for at least 90 days a prospectus covering the Common Stock meeting the requirements of such securities laws, and to furnish the Grantee such numbers of copies of the registration statement and prospectus as amended or supplemented as may reasonably be requested. The Grantor shall bear the cost of the registration, including, but not limited to, all registration and filing fees, printing expenses, and fees and disbursements of counsel and accountants for the Grantor, except that the Grantee shall pay the fees and disbursements of its counsel, the underwriting fees and selling commissions applicable to the shares of Common Stock sold by the Grantee. The Grantor shall indemnify and hold harmless Grantee, its affiliates and its officers and directors from and against any and all losses, claims, damages, liabilities and expenses arising out of or based upon any statements contained in, omissions or alleged omissions from, each registration statement filed pursuant to this paragraph; provided, however, that this provision does not apply to any loss, liability, claim, damage or expense to the extent it arises out of any untrue statement or omission made in reliance upon and in conformity with written information furnished to the Grantor by the Grantee, its affiliates and its officers expressly for use in any registration statement (or any amendment thereto) or any preliminary prospectus filed pursuant to this paragraph. The Grantor shall also indemnify and hold harmless each underwriter and each person who controls any underwriter within the meaning of either the Securities Act or the Securities Exchange Act of 1934 against any and all losses, claims, damages, liabilities and expenses arising out of or based upon any statements contained in, omissions or alleged omissions from, each registration statement filed pursuant to this paragraph; provided, however, that this provision does not apply to any loss, liability, B-9 86 claim, damage or expense to the extent it arises out of any untrue statement or omission made in reliance upon and in conformity with written information furnished to the Grantor by the underwriters expressly for use in any registration statement (or any amendment thereto) or any preliminary prospectus filed pursuant to this paragraph. 11. PROFIT LIMITATION. (a) Notwithstanding any other provision of this Agreement, in no event shall the Grantee's Total Profit (as defined in Section 11(c) below) exceed $30 million and, if it otherwise would exceed such amount, the Grantee, at its sole election, shall either (i) deliver to the Grantor for cancellation Shares previously purchased by Grantee, (ii) pay cash or other consideration to the Grantor or (iii) undertake any combination thereof, so that Grantee's Total Profit shall not exceed $30 million after taking into account the foregoing actions. (b) Notwithstanding any other provision of this Agreement, this Option may not be exercised for a number of Shares as would, as of the date of the Stock Exercise Notice, result in a Notional Total Profit (as defined in Section 11(d) below) of more than $30 million and, if exercise of the Option otherwise would exceed such amount, the Grantee, at its discretion, may increase the Purchase Price for that number of Shares set forth in the Stock Exercise Notice so that the Notional Total Profit shall not exceed $30 million; provided, that nothing in this sentence shall restrict any exercise of the Option permitted hereby on any subsequent date at the Purchase Price set forth in Section 1(a) hereof. (c) As used herein, the term "Total Profit" shall mean the aggregate amount (before taxes) of the following: (i) the amount of cash received by Grantee pursuant to Section 8.03(e) of the Merger Agreement and Section 1(c) hereof, (ii) (x) the amount received by Grantee pursuant to the Grantor's repurchase of Shares pursuant to Sections 8 or 9 hereof, less (y) the Grantee's purchase price for such Shares, and (iii) (x) the net cash amounts received by Grantee pursuant to the sale of Shares (or any other securities into which such Shares are converted or exchanged) to any unaffiliated party, less (y) the Grantee's purchase price for such Shares. (d) As used herein, the term "Notional Total Profit" with respect to any number of Shares as to which Grantee may propose to exercise this Option shall be the Total Profit determined as of the date of the Stock Exercise Notice assuming that this Option were exercised on such date for such number of Shares and assuming that such Shares, together with all other Shares held by Grantee and its affiliates as of such date, were sold for cash at the closing market price for the Common Stock as of the close of business on the preceding trading day (less customary brokerage commissions). B-10 87 12. EXPENSES. Each party hereto shall pay its own expenses incurred in connection with this Agreement, except as otherwise specifically provided herein. 13. SPECIFIC PERFORMANCE. The Grantor acknowledges that if the Grantor fails to perform any of its obligations under this Agreement immediate and irreparable harm or injury would be caused to the Grantee for which money damages would not be an adequate remedy. In such event, the Grantor agrees that the Grantee shall have the right, in addition to any other rights it may have, to specific performance of this Agreement. Accordingly, if the Grantee should institute an action or proceeding seeking specific enforcement of the provisions hereof, the Grantor hereby waives the claim or defense that the Grantee has an adequate remedy at law and hereby agrees not to assert in any such action or proceeding the claim or defense that such a remedy at law exists. The Grantor further agrees to waive any requirements for the securing or posting of any bond in connection with obtaining any such equitable relief. 14. NOTICE.
