If the Company's stockholders approve such proposal by a majority of the total votes cast on the proposal, the Company shall then enter into an appropriate amendment of this Agreement with Purchasers to increase the Purchasers' Voting Limit to 20% of the Total Voting Power. If the Company's stockholders do not approve such proposal, Mr. Gilbert shall have the right within 30 days (or, if such transaction would result in liability under Section 16(b) of the Exchange Act, such longer period, up to six months from the date of purchase of the Warrants, as may be necessary to avoid such liability) after such stockholders' meeting to rescind some or all of the Warrants then outstanding and upon such rescission the Company shall pay Mr. Gilbert an amount equal to $1.52 per Warrant in cash and cancel a pro rata portion of the then outstanding principal amount of the Note. 5. Standstill Provisions. 5.1 Acquisition of Voting Securities. Until the earliest of (a) the seventh anniversary of the date hereof, (b) such date as the Gilbert Entities cease to Beneficially Own Voting Securities representing 5% or more of the Total Voting Power, and (c) the occurrence of a Change in Control or a Rights Plan Event (the earliest of such dates being referred to as the "Standstill Termination Date") and subject to the further provisions hereof, each Purchaser covenants and agrees that: (i) The Gilbert Entities will not, directly or indirectly, without the prior written consent of the Company, Beneficially Own any Voting Securities except for (A) the Shares, (B) shares of Common Stock issuable upon exercise of the Warrants, (C) shares of Common Stock issuable upon exercise of options granted to Mr. Gilbert under the Directors Plan or any other shares of Common Stock or rights to acquire Common Stock made available to non-employee directors of the Company pursuant to Company plans and (D) additional Voting Securities of the Company so long as the Voting Power of all such additional Voting Securities Beneficially Owned by the Gilbert Entities, together with the Voting Power of the shares referred to in clauses (A), (B) and (C) then Beneficially Owned by the Gilbert Entities (calculated without giving effect to paragraph (ii) of this Section 5.1), does not equal or exceed 25% of the Total Voting Power; (ii) Subject to Section 4.8, if at any time the Gilbert Entities Beneficially Own Voting Securities representing more than 1,056,978 votes ("Purchasers' Voting Limit"), then the Gilbert Entities shall take such action as shall be required so that all shares of Voting Securities Beneficially Owned by the Gilbert Entities representing votes in excess of such number are voted in the same proportion as the votes cast by other holders of Voting Securities on all matters to be voted on by the holders of Voting Securities (including, without limitation, matters relating to mergers or other business combinations). Notwithstanding the foregoing, the Gilbert Entities shall be free to vote all of their Voting Securities in such manner as they determine in their sole discretion with respect to any Low Return Transaction (as defined in Section 5.4(b)); and (iii) The Gilbert Entities (A) shall be present, in person or by proxy, at all stockholders' meetings of the Company so that all outstanding Voting Securities Beneficially Owned by the Gilbert Entities shall be counted for the purpose of determining the presence of a quorum at such meetings and (B) subject to Section 5.1(ii), in any election of directors of the Company, shall vote all outstanding Voting Securities Beneficially Owned by the Gilbert Entities for the election of the Company's nominees as directors of the Company; provided, that the Company has complied with its obligations set forth in Section 4.5. 5.2 Restrictions on Transfer. Prior to the Standstill Termination Date, the Gilbert Entities shall not, directly or indirectly, sell, transfer, pledge, encumber or otherwise dispose of (collectively, "Transfer") any Voting Securities or the Warrants or any incidents of Beneficial Ownership of any Voting Securities or Warrants except for (i) Transfers after the second anniversary of the date hereof of shares of Common Stock pursuant to (x) the exercise of the registration rights set forth in the Registration Rights Agreement or (y) a transaction that complies with the volume, time period and manner of sale provisions contained in Rules 144(e) and (f) under the Securities Act as in effect at the time of such transaction; provided, that, except with respect to underwritten offerings pursuant to the Registration Rights Agreement, the Gilbert Entities shall use their best efforts (which shall include advising any broker of the provisions of this Section 5.2 but shall not require undue investigation on the part of the Gilbert Entities) so that no such Transfers under this clause (i) are made knowingly to any Person (including its Affiliates and any Person or entities which are, to Purchasers' knowledge after inquiry of the Company, part of any 13D Group which includes such transferee or any of its Affiliates) that, after giving effect to such Transfer, would Beneficially Own Voting Securities representing greater than 10% of the Total Voting Power, (ii) Transfers of shares of Common Stock pursuant to any bona fide tender or exchange offer to acquire shares of Common Stock; provided, that, during the first two years after the date hereof, such offer has been approved and recommended by the Company's Board of Directors or (iii) Transfers to an Affiliate of any Purchaser; provided, that such Affiliate becomes a signatory to, and agrees to be bound by, this Agreement. 5.3 Other Matters. Each Purchaser covenants and agrees that until the Standstill Termination Date, except solely by virtue of Mr. Gilbert's representation on the Board of Directors of the Company as provided in Section 4.5 hereof: (a) Neither any Purchaser nor any other Gilbert Entity thereof shall deposit any Voting Securities in a voting trust or subject any Voting Securities to any arrangement or agreement with respect to the voting of such Voting Securities or other agreement having similar effect (other than a voting trust, arrangement or agreement solely among the Purchasers and their Affiliates). (b) Neither any Purchaser nor any other Gilbert Entity shall solicit proxies or become a "participant" in a "solicitation" (as such terms are defined in Regulation 14A under the Exchange Act) in opposition to the recommendation of the majority of the directors of the Company with respect to any matter other than any charter or by-law amendment to be voted upon by the Company's stockholders that would adversely affect the rights of any such Purchaser, Mr. Gilbert or any other Gilbert Entity under this Agreement or adversely affect the rights of any such Purchaser, Mr. Gilbert or any other Gilbert Entity as a holder of Voting Securities in a discriminatory manner. (c) Neither any Purchaser nor any other Gilbert Entity thereof shall form, join or otherwise participate in a 13D Group or otherwise act in concert with any other Person who is not a Gilbert Entity for the purpose of acquiring, holding, voting or disposing of Voting Securities. (d) Other than pursuant to a direct request by the Company, neither any Purchaser nor any other Gilbert Entity thereof shall offer or propose (i) to enter into, directly or indirectly, any merger or other business combination involving the Company, (ii) to purchase, directly or indirectly, a material portion of the assets of the Company or (iii) to acquire any Voting Securities if such acquisition would be inconsistent with Section 5.1 hereof. (e) Neither any Purchaser nor any other Gilbert Entity thereof shall (i) disclose any intention, plan or arrangement inconsistent with the foregoing or (ii) advise, assist (including by knowingly providing or arranging financing for that purpose) or knowingly encourage any other Person in connection with any of the foregoing. 5.4 Notice of Certain Third Party Transactions. (a) Until the Standstill Termination Date, the Company shall give Purchasers written notice within two business days following receipt by the Company of any of the following: (i) any written or oral notice from any Person or group couched in such terms as to put the Company reasonably on notice of the likelihood that such Person or groups has acquired or is proposing to acquire any shares of Voting Securities which results in, or, if successful, would result in, such persons or group owning or having the right to acquire more than 15% of the Total Voting Power; (ii) any notice under the HSR Act relating to the Company; or (iii) any statement on Schedule 13D or Schedule 14D-1 (or any successor schedule or form to such schedules) under the Exchange Act relating to any Voting Securities of the Company. In its written notice to Purchasers, the Company shall disclose the material terms of such transaction, except that the Company need not disclose the name of the inquirer, purchaser or offeror, as the case may be. The Company may not enter into any definitive agreement relating to any such transaction until ten (10) business days have elapsed after Purchasers' receipt of the Company's notice under this Section 5.4(a). The Company shall have no obligation to update the information contained in any such notice. (b) If the Company desires to enter into a merger, consolidation or other business combination transaction in which the Company would not be the surviving corporation or in which the Company's outstanding Voting Securities were to be changed or exchanged for cash, stock or assets of another Person, or 50% or more of the Company's capital stock outstanding immediately after such merger, consolidation or other business combination transaction would not be owned by the stockholders of the Company immediately prior to such merger, consolidation or other business combination transaction or all or substantially all of the Company's assets or earning power would be sold, the Company shall give Purchasers written notice of such proposed transaction (a "Proposed Transaction") and the Company shall not enter into an agreement with respect to such Proposed Transaction and shall negotiate in good faith with Purchasers (but shall not be precluded from pursuing any such Proposed Transaction), in each case for a period of fifteen (15) business days after the date of such notice with a view towards reaching a mutually beneficial transaction with the Purchasers. The Company shall have no obligation to update the information contained in such notice unless the previously noticed terms are made materially less favorable to the Company, in which case the preceding and this sentence shall apply to such revised transaction. During such 15 business day period, the Company and the Purchasers shall keep confidential (subject to the requirements of applicable securities laws) the fact that such negotiations are occurring (including the terms discussed) and shall make no direct or indirect disclosure thereof to any other Person (other than their respective advisers). If, after such 15 business day period, the Company enters into an agreement with respect to such Proposed Transaction and, under the terms of such Proposed Transaction, Purchasers would receive proceeds in an amount that is less than the amount of their cash investment in the Shares, the Warrants and the Warrant Shares plus a return on such investment at the compounded rate of 10% per annum from the date of investment (which amount, in the case of a transaction involving the purchase of or an exchange for less than all of such Shares, Warrants and Warrant Shares, shall be computed solely on the basis of the proportion of such Shares, Warrants and Warrant Shares that would be sold in such Proposed Transaction) (a "Low Return Transaction"), then, notwithstanding the provisions of Section 5.1 or 5.3 hereof, Purchasers shall have the right to make and consummate one or more offers to the Company to acquire the Company in a merger transaction or to the stockholders to acquire all of their shares of Common Stock at a higher price than the price being offered in such Approved Transaction (with non-cash consideration valued at fair market value). 5.5 Restrictions on Amendments to the Rights Plan and Adoption of New Rights Plan. Until the Standstill Termination Date, the Board of Directors of the Company shall not (a) amend the definition of "Acquiring Person" set forth in the Rights Plan (as amended by the Rights Amendment) so as to deprive the Gilbert Entities of the benefits afforded by the Rights Amendment, (b) adopt any new rights plan pursuant to which holders of rights would be entitled to purchase securities upon the occurrence of certain "triggering events" at less than fair market value thereof which adopts a definition of "Acquiring Person" (or any functionally equivalent designation) which deprives the Gilbert Entities of the benefits afforded by the Rights Amendment or (c) cause any Gilbert Entity to become, for the purposes of any application of the Rights Plan, an "Acquiring Person" (or any functionally equivalent designation) solely by reason of its or his purchase of any Voting Securities in compliance with Section 5 of this Agreement. If an event described in Section 6.10(a) occurs, the Company shall at the same time amend the definition of "Acquiring Person" (or any functionally equivalent designation) to permit the Gilbert Entities to acquire Voting Securities representing such greater Total Voting Power. 5.6 Maintenance of Purchaser's Interest. From and after the date hereof until the Standstill Termination Date, upon the issuance or sale for cash by the Company of any Voting Securities (other than Voting Securities issued pursuant to options or rights to acquire Voting Securities granted or to be granted to officers, employees, consultants or directors pursuant to any stock plan, stock bonus, stock appreciation rights, stock purchase or other benefit plan relating to such classes or persons, hereafter adopted by those members of the Board of Directors who (i) in the case of officer and employee awards, are not officers or employees of the Company and (ii) in the case of all other awards, are not entitled to participate in any plan then the subject of approval other than automatic non-discretionary plans), the Company shall offer to Purchasers, by written notice to Purchasers given concurrently with such issuance or sale, the opportunity to acquire such number of Voting Securities on the same terms and conditions as such issuance or sale as shall allow the Gilbert Entities, immediately following the issuance or sale of all such Voting Securities, to be the Beneficial Owner, in the aggregate, of Voting Securities representing the same Total Voting Power as that represented by the Voting Securities owned by the Gilbert Entities immediately prior to the issuance or sale referred to in this Section 5.6 (without giving effect to Section 5.1(ii)). 5.7 Top Up Right. From and after the date hereof until the Standstill Termination Date, the Company covenants that, so long as the Gilbert Entities Beneficially Own Voting Securities representing 15% or more of the Total Voting Power, if the Company proposes to issue Voting Securities or securities convertible or exchangeable into Voting Securities to any Person or group of related Persons (a "Buyer") and, immediately after such issuance, such Buyer would Beneficially Own (a) capital stock representing a greater percentage of the total capital stock outstanding (determined on an as-converted basis) or (b) (after giving effect to Section 5.1(ii) with respect to the Gilbert Entities and any similar restriction with respect to such Buyer) Voting Securities representing a greater percentage of Total Voting Power, than the percentage of total Common Stock outstanding or Total Voting Power, respectively, Beneficially Owned by the Gilbert Entities at such time, then, notwithstanding the provisions of Section 5.1(i), the Company shall offer to Purchasers new Voting Securities (on the same terms and conditions as such issuance to Buyer) and/or amend the restrictions set forth in Section 5.1(ii) so that, after giving effect to such issuances and/or amendment, Buyer and the Gilbert Entities would Beneficially Own (i) the same number of shares of Common Stock and (ii) Voting Securities representing the same percentage of Total Voting Power (giving effect to Section 5.1(ii) as so amended with respect to the Gilbert Entities and any similar restriction with respect to Buyer). 5.8 Standstill Termination Events. Notwithstanding the provisions of Sections 5.1 and 5.3, if, in response to any tender or exchange offer to acquire Voting Securities made pursuant to a Schedule 14D-1 filed with the Commission (a "Tender Offer"), the Company (i) recommends acceptance of, or responds neutrally to, such Tender Offer (as evidenced by the Company's filing with the Commission of a Schedule 14D-9) or (ii) redeems the Rights issued under the Rights Agreement, the Gilbert Entities may make an offer to purchase for cash and purchase all outstanding shares of Common Stock at a higher price than the consideration being offered in the Tender Offer. 6.
