SECTION 2. CONVERSION OPTION. (a) Until February 14, 2001, if the Company shall initiate any transaction or be a party to any agreement or transaction resulting in any Equity Financing, then, as a condition of the consummation of all such Equity Financings, lawful, enforceable and adequate provision shall be made so that the Purchaser shall be entitled to elect, at its option, by written notice to the Company to convert the sum of the unpaid principal amount of the Note (including PIK Notes, if any) plus all accrued and unpaid interest thereon (the "Aggregate Note Amount") into fully paid and non-assessable securities of the identical price, type and kind of securities received by the purchasers in such Equity Financings. The number of securities to be received shall be determined by dividing the Aggregate Note Amount by the identical per share price being paid for the securities by the ultimate purchasers in the Equity Financing. The above provisions of this Section 2(a) shall apply to all Equity Financings which occur on or prior to February 14, 2001; provided, that if the Company has initiated or become a party to any agreement or transaction before February 14, 2001 which will result in an Equity Financing being consummated after February 14, 2001, then this Section 2(a) shall continue to apply until the consummation of such Equity Financing; provided, however, upon the closing of a Qualified Public Offering, the Aggregate Note Amount shall be automatically converted into fully paid and non-assessable securities of the identical price, type and kind of securities received in the Qualified Public Offering. The Company shall give written notice to the Purchaser no less than 20 days prior to the closing of such Equity Financing. Such notice shall contain all the material terms, including, but not limited to, the price, quantity and rights of the applicable security, of the Equity Financing. (b) In order to exercise the conversion privilege, the Purchaser of any note to be converted shall on or before the 10th day after receipt of the Company's notice of an Equity Financing surrender such note, duly endorsed or assigned to the Company or in blank at any office or agency of the Company, accompanied by written notice to the Company at such office or agency that the Purchaser elects to convert such note or, if less than the entire principal amount thereof is to be converted, the portion thereof to be converted. Notes shall be deemed to have 3 4 been converted immediately prior to the close of business on the day of surrender of such notes for conversion in accordance with the foregoing provisions, and at such time the rights of the Purchaser of such notes as Purchaser shall cease, and the Person or Persons entitled to receive the securities issuable upon conversion shall be treated for all purposes as the record purchaser or purchasers of such securities at such time. As promptly as practicable on or after the conversion date, the Company shall issue and shall deliver at such office or agency a certificate or certificates for the number of full shares of securities issuable upon conversion, together with payment in lieu of any fraction of a share, as provided in Section 1(c). In the case of any note that is converted in part only, upon such conversion the Company shall execute a new note in aggregate principal amount equal to the unconverted portion of the principal amount of such note. (c) No fractional shares of securities shall be issued upon conversion of the note. If more than one note shall be surrendered for conversion at one time by the same Purchaser, the number of full shares that shall be issuable upon conversion thereof shall be computed on the basis of the aggregate principal amount of the notes (or, specified portions thereof) so surrendered. Instead of any securities that would otherwise be issuable upon conversion of any note or notes (or, specified portions thereof), the Company shall pay a cash adjustment in respect of such fraction in an amount equal to the same fraction of the per share purchase price of a share of such securities. (d) As a condition of the exercise of the conversion right, the Purchaser shall execute and become a party to all documents involved in such Equity Financing which are reasonably acceptable to the Purchaser and are executed by other purchasers in such Equity Financing (including, without limitation, shareholder agreements, registration rights agreements, purchase agreements, and, if such Equity Financing is a Qualified Public Offering, a 180-day lock-up agreement). SECTION 3. RIGHT TO INVEST IN EQUITY FINANCINGS. (a) Right to Invest. In the event the Company redeems all or any portion of the Note (or PIK Notes, if any) on or before February 14, 2001, from the proceeds of a source of funds other than an Equity Financing, and in the event the Company conducts any Equity Financing during the 12 months after the date of redemption, then the Company hereby agrees to give prior written notice to the Purchaser and grants to the Purchaser the option to purchase securities issued in such Equity Financing with an aggregate purchase price equal to the Allocable Portion, at the price and upon the same terms set forth in such transaction. Such options shall be exercisable by written notice to the Company for a period of 20 days from the date of such offer and shall follow the procedures set forth in Sections 2(b), 2(c) and 2(d). The closing of the purchase of such securities by the Purchaser shall take place concurrently with the closing of such Equity Financing. 4 5 (b) As a condition of the exercise of the rights under this Section 3, the Purchaser shall execute and become a party to all documents involved in such Equity Financing which are reasonably acceptable to the Purchaser and are executed by the other purchasers in such Equity Financing (including, without limitation, shareholder agreements, registration rights agreements, purchase agreements, etc.). SECTION 4. MERGER OR SIMILAR TRANSACTION. If, on or before February 14, 2001, the Company shall merge, consolidate, exchange or close any similar transaction with an unaffiliated entity which does not have a class of equity securities registered under the Securities Exchange Act of 1934, as amended (the "Acquiring Company"), in any such case where securities of the Acquiring Company are being issued in exchange for, or otherwise in return for, all or substantially all of the outstanding securities of the Company (a "Sale Transaction"), the Purchaser shall have the right to convert all or a portion of the outstanding principal and accrued interest on the Notes into shares of the Class A common stock of the Company, in the manner set forth in Section 2 above. The number of shares of the Class A common stock of the Company to be issued in connection with such conversion shall be equal to the dollar amount of the Notes to be converted, divided by the transaction per share value of a share of the Company's Class A common stock in the Sale Transaction. The Purchaser shall execute all documents reasonably required to be signed by the holders of the Class A common stock in connection with the Sale Transaction. The Company shall provide the Purchaser with written notice of the proposed Sale Transaction within 20 days prior to the closing thereof. Such notice shall contain all the material terms, including, but not limited to, the price, quantity and rights of the applicable security, of the Equity Financing. If the Purchaser desires to convert all or a portion of the Notes, it shall provide written notice to the Company within 10 days after receipt of the Company's notice. Upon the closing of the Sale Transaction, the Purchaser, shall have no other rights pursuant to Sections 2 or 3 of this Agreement. SECTION 5. ASSIGNABILITY; SUCCESSORS AND ASSIGNS. Neither the Company nor the Purchaser may assign or transfer (by operation of law or otherwise) its rights and obligations, in whole or in part, under this Agreement to any third party without the prior written consent of the other party; provided, however, that the Purchaser may assign such rights and obligations to an affiliate of the Purchaser without obtaining such consent. The rights and obligations of the Purchaser and the Company hereunder shall inure to the benefit of, and be binding and enforceable upon, the respective successors, and permitted assigns or transferees of the Purchaser and the Company. SECTION 6. REMEDIES. The Company stipulates that the remedies at law of the Purchaser in the event of any default or threatened default by the Company in the performance of or compliance with any of the terms of this Agreement are not and will not be adequate, and that such terms may be specifically enforced by a decree for the specific performance of any agreement contained herein or by an injunction against a violation of any of the terms hereof or otherwise. 5 6 SECTION 7. NOTICES. Except as otherwise provided herein, any notices hereunder shall be deemed to have been received (a) when delivered, if personally delivered or sent via facsimile, or (b) one day following delivery to a nationally recognized overnight courier or (c) on the third business day following the date on which the piece of mail containing such communication is posted, if sent by certified or registered mail, return receipt requested, in each case addressed to the principal office of the Company, Attention: President. SECTION 8. MISCELLANEOUS. This Agreement and any term hereof may be changed, waived, discharged or terminated only by an instrument in writing signed by both the Company and the Purchaser. This Agreement shall be construed and enforced in accordance with, and governed by the laws of, the State of North Carolina. This Agreement may be executed in one or more counterparts each of which shall be deemed an original, but all of which together shall constitute one and the same agreement. The headings in this Agreement are for purposes of reference only, and shall not limit or otherwise affect any of the terms hereof. SECTION 9. COMPLIANCE WITH LAWS. The exercise by the Purchaser of its rights hereunder shall be subject to compliance with applicable securities laws (including without limitation Section 5 of the Securities Act of 1933, as amended, as it relates to the integration of offerings) and the rules and regulations of self-regulatory organizations (including without limitation, the National Association of Securities Dealers, including those governing underwriters' compensation, free writing and withholding). If, at the time of the proposed exercise of any of the Purchaser's rights hereunder, the exercise of such rights would violate any of such laws or regulations, the parties agree to modify this Agreement and use their respective best efforts to preserve the economic benefits provided by this Agreement, and the Company shall compensate the Purchaser in such a way as to realize the benefit of its rights hereunder; provided, however, that if the violation is based on the amount of the economic benefit to be received, an appropriate adjustment in such amount shall be agreed to by the parties. SECTION 10. PROTECTIVE PROVISION. The Company agrees to not permit any entity which is controlled by the Company or by the Holding Company to consummate an initial public offering of capital stock pursuant to the Securities Act of 1933, as amended, without providing the Purchaser the option to realize the benefit of its rights hereunder. 6 7 IN WITNESS WHEREOF, the parties hereto have executed this Agreement as of the date first above written.
