Stockholders' Rights of First Refusal on Company's Issuance of Equity Equivalents. (a) If at any time the Company wishes to issue any equity securities or any options, warrants or other rights to acquire equity securities (collectively, the "Equity Equivalents") to any Person or Persons, the Company shall promptly deliver a notice of intention to sell (the "Company's Notice of Intention to Sell") to each Stockholder setting forth a description of the Equity Equivalents to be sold and the proposed purchase price and terms of sale. Upon receipt of the Company's Notice of Intention to Sell, each Stockholder shall have the right to elect to purchase, at the price and on the terms stated in the Company's Notice of Intention to Sell, a number of the Equity Equivalents equal to such Stockholder's aggregate proportionate ownership of Common Stock and rights to acquire Common Stock (calculated on a fully-diluted basis assuming all holders of then outstanding warrants, options and convertible securities of the Company had converted such securities or -11- 12 exercised such warrants or options immediately prior to the taking of the record of the holders of Common Stock for the purpose of determining whether they are entitled to receive such offer) held by all Stockholders multiplied by the number of Equity Equivalents to be issued. Such election is to be made by the electing Stockholder by written notice to the Company within ten (10) days after receipt by such Stockholder of the Company's Notice of Intention to Sell (the "Acceptance Period for Equity Equivalents"). Each Stockholder shall also have the option, exercisable by so specifying in such written notice, to purchase on a pro rata basis similar to that described above, any remaining Equity Equivalents not purchased by other Stockholders, in which case the Stockholders exercising such further option shall be deemed to have elected to purchase such remaining Equity Equivalents on such pro rata basis as described above (provided that the denominator used to determine pro rata ownership shall be the number of shares of Common Stock, determined on a fully diluted basis, held by all holders exercising such further option). In the event that the Equity Equivalents to be issued at any time as contemplated by this Section 6 are either voting securities of the Company or securities which are convertible, exercisable or otherwise exchangeable for voting securities of the Company and for any reason one or more of the Stockholders determines in its sole discretion that it would be detrimental to such Stockholder or its affiliates to purchase such securities as provided for hereby, then the Company shall make available to any such Stockholder an amount of alternative securities equal to the amount of such Equity Equivalents as such Stockholder is entitled to purchase pursuant to the terms hereof which are identical to such Equity Equivalents in all respects except for the fact that such alternate securities shall be non-voting securities or convertible, exercisable or otherwise exchangeable for non-voting securities (the "Alternative Securities"). (b) If effective acceptance shall not be received pursuant to paragraph (a) above in respect of all the Equity Equivalents or Alternative Securities, then the Company may, at its election, during a period of one hundred and twenty (120) days following the expiration of the Acceptance Period for Equity Equivalents, sell and issue the remaining Equity Equivalents to another person at a price and upon terms not more favorable to such person than those stated in the Company's Notice of Intention to Sell; provided, however, that failure by a Stockholder to exercise its option to purchase with respect to one offering, sale and issuance of Equity Equivalents shall not affect its option to purchase Equity Equivalents or rights to acquire Equity Equivalents in any subsequent offering, sale and purchase. In the event the Company has not sold the Equity Equivalents, or entered into a binding agreement to sell the Equity Equivalents, within such one hundred and twenty (120) day period, the Company shall not thereafter issue or sell any Equity Equivalents without first offering such securities to each Stockholder in the manner provided in Section 6(a) hereof. (c) If a Stockholder gives the Company notice, pursuant to the provisions of this Section 6, that such Stockholder desires to purchase any of the Equity Equivalents or Alternative Securities, payment therefor shall be by check or wire transfer, against delivery of the securities at the executive offices of the Company within ten (10) days after giving the Company such notice, or, if later, the closing date as mutually agreed between the Company and such Stockholder for the sale of such Equity Equivalents or Alternative Securities. In the event that any such proposed issuance is for a consideration other than cash, such Stockholders will be entitled to pay cash for each share or other unit, in lieu of such other consideration, in the amount determined in good faith by the Board to constitute the fair value of such consideration other than cash to be paid per share or other unit. -12- 13 (d) The right of first refusal contained in this Section 6 shall not apply to (i) the issuance of shares of Common Stock as a stock dividend or upon any subdivision or stock split of the outstanding shares of Common Stock; (ii) the issuance of shares of Common Stock upon conversion of any shares of convertible securities (including, without limitation, the Series A Preferred Stock); (iii) the issuance of shares of Common Stock, or the grant of options, warrants or rights to subscribe for shares of Common Stock, to officers, directors and other employees of the Company and to consultants to the Company pursuant to stock options to purchase up to 63,830 shares of Common Stock that are issued pursuant to the Stock Option Plan or such other options that are granted to such persons and that are approved by a majority of the entire Board (in each case, as such number of shares may be adjusted from time to time in accordance with the terms of the Stock Option Plan or agreements evidencing grants thereunder); or (iv) the issuance of Common Stock pursuant to any under-written public offering. 7. Transfer of Investor Stock. (a) Shares of Investor Stock are transferable only pursuant to (i) public offerings registered under the Securities Act, and (ii) subject to the provisions of Section 3 and Section 4 above, Rule 144 or Rule 144A (or any similar rule or rules then in effect) of the SEC if such rule is available, and (iii) subject to Section 3, Section 4 and Section 7(b) below, any other legally available means of Transfer. (b) In connection with the Transfer of any shares of Investor Stock other than a Transfer described in clause (i) or (ii) of Section 7(a) above, the holder thereof shall deliver written notice to the Company describing in reasonable detail the Transfer or proposed Transfer, together with an opinion of counsel reasonably acceptable to the Company to the effect that such Transfer of shares of Investor Stock may be effected without registration of such shares of Investor Stock under the Securities Act. In addition, if the holder of the shares of Investor Stock delivers to the Company an opinion of counsel that no subsequent Transfer of such shares of Investor Stock shall require registration under the Securities Act, the Company shall promptly upon such contemplated Transfer deliver new certificates for such shares of Investor Stock which do not bear the legend set forth in Section 7 below. If the Company is not required to deliver new certificates for such shares of Investor Stock not bearing such legend, the holder thereof shall not consummate a Transfer of the same until the prospective transferee has confirmed to the Company in writing its agreement to be bound by the conditions contained in this Section 7 below. (c) Upon the request of a holder of Investor Stock, the Company shall promptly supply to such Person or its prospective transferees all information regarding the Company required to be delivered in connection with a Transfer pursuant to Rule 144A or Rule 144 (or any similar rule or rules then in effect) of the SEC. (d) Upon the request of any holder of Investor Stock, the Company shall remove the legend set forth in Section 10 below from the certificates for such holder's shares of Investor Stock; provided, that such shares of Investor Stock are eligible for sale pursuant to Rule 144(k) (or any similar rule or rules then in effect) of the SEC. -13- 14 8. Deliveries. The Company shall furnish to each Investor, for so long as such Investor holds any Stockholder Shares: (a) Financial Information. (i) Within 30 days after the end of the second fiscal quarter of each fiscal year, a copy of the consolidated balance sheets of the Company and its Subsidiaries as of the end of such period, and the related consolidated statements of income, changes in stockholders' equity, and cash flow for the period then ended, prepared in accordance with GAAP (subject to normal year-end adjustments and the exclusion of such footnotes as may be required in accordance with GAAP), and accompanied by comparisons to the Company's annual budget and to the corresponding periods in the preceding fiscal year. (ii) Within 90 days after the end of each fiscal year, a copy of the audited consolidated balance sheets of the Company and its Subsidiaries as of the end of such period, and the related consolidated statements of income, changes in stockholders' equity, and cash flow for the period then ended, setting forth in comparative form in each case the consolidated figures for the previous fiscal year-end, which financial statements shall be prepared in accordance with GAAP and certified without qualification by Ernst & Young, L.L.P. or any other "big-six" accounting firm selected by the Company. (iii) Not later than the commencement of each fiscal year, an annual business plan, including a budget and detailed financial projections for the Company, for such fiscal year, together with underlying assumptions thereto. (b) Notices to Stockholders. Promptly after the furnishing thereof, copies of any report, letter, notice, statement or other information furnished by the Company to the Stockholders. (c) Other Information. With reasonable promptness, such other data and information as from time to time may be reasonably requested by any Investor. 8A. Inspection Rights. Each Investor shall have reasonable access to the Company's and each Subsidiary's books and records, and other documents and data of the Company and each Subsidiary, and any such Investor may, at its own expense, make copies of all such books and records, and other documents and data. Without limiting the rights of each Investor as provided in this Section 8A, the Investor shall use reasonable efforts to coordinate their inspection so as not to burden unreasonably the Company or any Subsidiary. 9. Put Arrangements. (a) If (x) the Company shall not have consummated an Initial Public Offering by the third anniversary of the date hereof (such date, the "Third Anniversary") or (y) the Company consummates an Approved Sale or consummates a public offering or liquidates, each Investor shall have the right within ninety (90) days following the Third Anniversary or prior to or simultaneously with the closing of the Approved Sale, public offering, or liquidation (the "Put Period"), to require the Company to repurchase all or any portion of the Common Stock held by such Investor at the Put Price (the "Put") by delivering written notice to the Company specifying the number of shares of -14- 15 Common Stock to be repurchased by the Company (the "Put Notice"). The right to exercise the Put shall inure to the benefit of all Transferees of Investor Stock (other than transferees in a Public Sale). (b) Within ten (10) Business Days after an Investor delivers a Put Notice to the Company, the Company shall purchase and such Investor (the "Selling Investor") shall sell the number of shares of Common Stock specified in the Put Notice at a mutually agreeable time and place (the "Put Closing"). (c) At the Put Closing, the Selling Investor shall deliver to the Company certificates representing the shares of Common Stock to be repurchased by the Company free and clear of all liens and encumbrances and duly endorsed in blank or accompanied by duly executed forms of assignment, and the Company shall deliver to the Selling Investor the Put Price by cashier's or certified check payable to the Selling Investor or by wire transfer of immediately available funds to an account designated by the Selling Investor; provided, that if and to the extent any such purchase for cash is prohibited by (x) the provisions of applicable state law or (y) the terms and conditions of the Company's financing agreements with its primary lender such that the Put Closing would cause a default under the terms and conditions of such financing agreements, the amount of the Put Price which is not able to be paid in cash shall be paid for by the issuance of subordinated promissory notes with a maturity of ten years and bearing interest on the unpaid principal amount of such notes at a rate equal to the Prime Rate, in each case subject to the terms and conditions of the Company's financing agreements; provided, further, that the Selling Investor shall be entitled to rescind any portion of the exercised Put if any portion of the Put Price would be payable by a subordinated promissory note; and provided further, that the Company shall use its reasonable best efforts to arrange alternate financing in order to pay the Put Price in cash and will give the Investor notice at such time as alternate financing has been arranged. Notwithstanding any limitation contained herein on the period during which an Investor may exercise the Put, in the event a Selling Investor rescinds any portion of the exercised Put pursuant to the foregoing sentence of this Section 9(c) (a "Put Recission"), such Selling Investor shall be entitled to exercise the Put at any time following a Put Recission in accordance with the terms and conditions of this Section 9. 9A. Negative Covenants. Without the prior written approval of the holder or holders of a majority of the shares of Investor Stock then outstanding, the Company will not: (i) declare or pay any dividends, or make any distributions, upon the Common Stock; (ii) redeem, purchase or otherwise acquire any of the Common Stock, except for redemptions, purchases or acquisitions of Common Stock held by members of management of the Company in connection with the death, disability or termination of employment of any such Persons; (iii) enter into (directly or indirectly), or permit any Subsidiary to enter into, any transaction with any officer, director or stockholder of the Company, any of their respective Affiliates, or any entity in which any officer, director or stockholder of the Company or any of their respective Affiliates may have an interest on terms less favorable than the Company could obtain in a transaction with an unrelated party; or -15- 16 (iv) become subject to, or permit any of its Subsidiaries to become subject to, any agreement or instrument, which by its terms would materially restrict the Company's right to perform any of its obligations pursuant to the terms of this Agreement. 10.
