(a) The Company shall not, directly or indirectly, without the prior written consent of the Purchaser, offer, sell, grant any option to purchase or otherwise dispose (or announce any offer, sale, grant or any option to purchase or other disposition) of any of its or its Affiliates equity or equity equivalent securities (a "Subsequent Sale") for a period of 180 days after the Closing Date, except (i) upon conversion of any of the Preferred Stock or the Series C Preferred Stock or exercise of any of the Warrants or warrants heretofore issued in connection with the Series C Preferred Stock, (ii) as a stock dividend or upon any subdivision of shares of Common Stock, provided that the securities -13- 15 issued pursuant to such stock dividend or subdivision are limited to additional shares of Common Stock, (iii) pursuant to subscriptions, warrants, options, convertible securities or other rights which are outstanding on the Closing Date, (iv) solely in consideration for the acquisition (whether by merger or otherwise) by the Company or any of its Subsidiaries of all or substantially all of the stock or assets of any other entity, (v) pursuant to a primary registered public offering under the Securities Act, other than an offering subject to Rule 415 under the Securities Act, (vi) pursuant to the exercise of options or purchase rights to purchase Common Stock granted to employees, consultants and directors of the Company pursuant to any stock purchase, stock option or employee stock bonus plan approved by the Board of Directors, (vii) securities issued to equipment lessors in connection with lease of corporate equipment by the Company as approved by the Company's Board of Directors, (viii) upon the exercise of any right other than a right to purchase securities which was not itself in violation of the terms of this paragraph, and (ix) securities issued in connection with refinancing the Company's existing bank debt, not more than 200,000 shares in any calendar year unless (A) the Company delivers to the Purchaser a written notice (the "Subsequent Sale Notice") of its intention to effect such Subsequent Sale, which Subsequent Sale Notice shall describe in reasonable detail the proposed terms of such Subsequent Sale, the identity of the Persons who proposes to provide such Subsequent Sale and the amount of proceeds intended to be raised thereunder and (B) the Purchaser shall not have notified the Company by 5:00 p.m. (Eastern Time) on the tenth Business Day after its receipt of the Subsequent Sale Notice of its willingness to enter into good faith negotiations to provide (or to cause its sole designee to provide) financing to the Company on substantially the terms set forth in the Subsequent Sale Notice. If the Purchaser shall fail to notify the Company of its intention to enter into such negotiations within such time period, the Company may effect the Subsequent Sale substantially upon the terms and to the Persons (or Affiliates of such Persons) set forth in the Subsequent Sale Notice; provided, that the Company shall provide the Purchaser with a second Subsequent Sale Notice, and the Purchaser shall again have the right of first refusal set forth above in this paragraph (a), subject to the exceptions set forth above in this paragraph (a), if the Subsequent Sale subject to the initial Subsequent Sale Notice shall not have been consummated for any reason on the terms set forth in such Subsequent Sale Notice within 90 days after the date of the initial Subsequent Sale Notice with the Person (or an Affiliate of such Person) identified in the Subsequent Sale Notice. (b) For as long as Preferred Stock or Warrants outstanding, the Company shall not and shall cause the Subsidiaries not to, without the consent of the Purchaser, (i) amend its Restated Articles of Organization, bylaws or other charter documents so as to adversely affect any rights provided in the Transaction Documents to the Preferred Stock and the Warrants; (ii) split, combine or reclassify its outstanding capital stock; (iii) redeem, repurchase or offer to repurchase or otherwise acquire shares of its Junior Securities (as defined in the Statements of Rights and Preferences); or (iv) enter into any agreement with respect to any of the foregoing. Section 4.13. Notwithstanding anything to the contrary contained herein, each Conversion Notice shall contain a representation that, after giving effect to the shares of the Company's Common Stock to be issued pursuant to such Conversion Notice, the total number of shares of the Company's Common Stock deemed beneficially owned by the holder thereof, together with all shares of the Company's Common Stock deemed beneficially owned by such holder's "affiliates" as defined in Rule 144 promulgated under the Securities Act of 1933, as amended, (exclusive of shares issuable upon conversion of the unconverted portion of the Shares of Series D Preferred Stock or the unexercised or unconverted portion of any other securities of the Company subject to a limitation on conversion or exercise analogous to the limitations contained herein) will not result in beneficial ownership by the holder and its affiliates of more -14- 16 than 4.9% of the outstanding shares of Common Stock. For purposes of this subparagraph, beneficial ownership shall be determined in accordance with Section 13(d) of the Securities Exchange Act of 1934, as amended, and Regulation 13 D-G thereunder, except as other provided above. Any Conversion Notice which does not contain such representation shall be ineffective provided, however, that the requirement of this paragraph shall not apply to any Purchaser marked as "excluded from Section 4.13" on Schedule A. Section 4.14. Availability of Common Stock. The Company has duly reserved a sum of 5,200,000 shares of authorized and unissued Common Stock for issuance upon the conversion of Series D Shares and the exercise all of the Series D Warrants. If at any time the Company does not have reserved sufficient shares of Common Stock to enable it to perform its conversion and exercise obligations hereunder with respect to all shares of Preferred Stock and all Warrants then outstanding it shall, at the option of the holders of Preferred Stock, redeem all Shares and Underlying Shares then held by such holders, pursuant to Section 4.16 hereto. Section 4.15. Listing of Underlying Shares and Warrant Shares. Prior to the Closing, the Company shall have filed an additional listing application with the Nasdaq National Market or SmallCap Market, as the case may be (and each other national securities exchange on which the Common Stock is then listed) for the listing of the Underlying Shares and the Warrant Shares. The Company shall, as promptly as possible, take all steps necessary to cause the Underlying Shares and Warrant Shares to be approved for listing in the Nasdaq National Market or SmallCap Market (and each other national securities exchange or market on which the Common Stock is then listed), and shall provide to the Purchaser evidence of such listing when approved and shall maintain the listing of its Common Stock on such exchange. Section 4.16. Purchaser's Rights if Trading in Common Stock is Suspended or Delisted. In the event that at any time within the three-year period after the Closing Date trading in the shares of the Common Stock is suspended, or if the Common Stock shall not listed for trading, on the Nasdaq National Market (other than as a result of the suspension of trading in securities on such market or exchange generally or temporary suspensions pending the release of material information and other than a suspension of trading on the Nasdaq National Market if the Common Stock is listed for trading, and not suspended, on the Nasdaq SmallCap Market within one Business Day after such suspension) for more than ten days, at the Purchaser's option exercisable by written notice to the Company, the Company shall redeem for cash all Shares and all Underlying Shares then held by such Purchaser, at an aggregate purchase price equal to (A) the product of the average Per Share Market Value for the five Trading Days immediately preceding the day of such notice multiplied by the number of shares of Common Stock into which the Shares to be purchased are then convertible and exercisable (or in the case of Underlying Shares, the number of Underlying Shares to be purchased), plus (B) interest on such amount accruing from the 7th day after such notice at the rate of 15% per annum. Section 4.17. No Violation of Applicable Law. Notwithstanding any provision of this Agreement to the contrary, if any redemption of Shares or Underlying Shares otherwise required under the Transaction Documents or the Statements of Rights and Preferences would be prohibited by the relevant provisions of the Massachusetts Business Corporation Law, such redemption shall be effected as soon as it is permitted under such law; provided, however, that, interest payable by the Company with respect to any such redemption shall continue to accrue in accordance with Section 4.16 during any such period. -15- 17 Section 4.18. Redemption Restrictions. Notwithstanding any provision of this Agreement to the contrary, if any redemption of Shares or Underlying Shares otherwise required under this Agreement would be prohibited in the absence of consent from any lender of the Company or of any Subsidiary, or by the holders of any class of securities of the Company, the Company shall use its best efforts to obtain such consent as promptly as practicable after the redemption is required but in no event later than 30 days after the redemption is required. Interest payable by the Company with respect to any such redemption shall continue to accrue in accordance with Section 4.16 until such consent is obtained. Nothing contained in this Section shall be construed as a waiver by the Purchaser of any rights it may have by virtue of any breach of any representation or warranty of the Company herein as to the absence of any requirement to obtain any such consent. Section 4.19. Notice of Breaches. Each of the Company and the Purchaser shall give prompt written notice to the other of any breach of any representation, warranty or other agreement contained in the Transaction Documents, as well as any events or occurrences arising after the date hereof and prior to the Closing Date, which could reasonably be likely to cause any representation or warranty or other agreement of such party, as the case may be, contained herein or therein to be incorrect or breached as of such Closing Date. However, no disclosure by either party pursuant to this Section shall be deemed to cure any breach of any representation, warranty or other agreement contained herein or in the other Transaction Documents. Neither the Company, any Subsidiary nor the Purchaser will take, or agree to commit to take, any action that is intended to make any representation or warranty of the Company or the Purchaser, as the case may be, contained herein or in the other Transaction Documents or in the Statements of Rights and Preferences inaccurate in any respect at such Closing Date. Notwithstanding the generality of the foregoing, the Company shall promptly notify the Purchaser of any notice or claim (written or oral) that it receives from any lender of the Company to the effect that the consummation of the transactions contemplated by the Transaction Documents violates or would violate any written agreement or understanding between such lender and the Company, and the Company shall promptly furnish by facsimile to the holders of the Shares and Warrants a copy of any written statement in support of or relating to such claim or notice. Section 4.20. The Warrants. (a) The Series D Warrants. At the Series D Closing, the Company shall issue to each Purchaser three Common Stock purchase warrants (the "Series D Warrants"), in accordance with the following terms: (i) one Series D Warrant shall entitle the Purchaser to acquire 0.66666 shares of Common Stock for each share of Preferred Stock being purchased by that Purchaser at a price per share equal to 125% of the average Per Share Market Value for the ten trading days immediately preceding the Closing Date (the "Average Price") in accordance with the terms thereof and shall be exercisable through the date that is three years after the Closing Date, (ii) one Series D Warrant shall entitle the Purchaser to acquire 0.66666 shares of Common Stock for each share of Preferred Stock being purchased by that Purchaser at a price per share equal to 135% of the Average Price in accordance with the terms thereof and shall be exercisable through the date that is four years after the Closing Date, and (iii) one Series D Warrant shall entitle the Purchaser to acquire 1.0 share of Common Stock for each share of Preferred Stock being purchased by that Purchaser at a price per share equal to 150% of the Average Price in accordance with the terms thereof and shall be exercisable through the date that is five years after the Closing Date. -16- 18 (b) The Warrants shall be substantially in the form of Exhibit E.
