ARTICLE IV TAG ALONG RIGHTS Until the earlier of (a) the effective date of an IPO Event or (b) the date when Thayer's Pro Rata Share (together with any Affiliates of Thayer) is less than fifty-one percent (51%), Thayer shall not engage in a transaction (including a merger, consolidation or similar business combination) that involves the Transfer by Thayer (together with any Affiliates of Thayer) to a third party of Common Stock representing greater than fifty percent (50%) of the outstanding Common Stock held by Thayer (other than a "Drag Along Sale" as defined in Article V below and other than a Transfer to one or more Affiliates --------- of Thayer and/or Family Members of such Affiliates) without first offering the other Stockholders the right to participate in such Transfer in the following manner: 4.1 Notice.

The Tag Along Notice shall specify the maximum number of Common Stock shares that the Stockholder (a "Tag Along Stockholder") may elect to Transfer which number shall not exceed the product (rounded down to the nearest whole number) of (i) a fraction, the numerator of which is the number of Common Stock shares proposed to be Transferred by Thayer, and the denominator of which is the aggregate number of Common Stock shares owned by Thayer, multiplied by (ii) the number of shares of Common Stock owned by the Stockholder plus the number of shares of Equity Securities then convertible into Common Stock or which will become convertible into Common Stock as a result of the transaction contemplated by the Transfer Notice. Thayer shall use its commercially reasonable best efforts to interest the third party in purchasing all the shares of Common Stock specified by Tag Along Stockholders in the Tag Along Notices, in addition to -5- the Common Stock that the third party may already have agreed to purchase from Thayer.

At least five - ---------- (5) days prior to the date of such consummation, each Tag Along Stockholder shall deliver to Thayer for Transfer to the third party one or more certificates, properly endorsed for Transfer, which represent the number of shares of Common Stock such Tag Along Stockholder is entitled to sell as provided in the Consummation Notice. The certificate(s) delivered to Thayer by each Tag Along Stockholder shall be Transferred to the third party identified in the Consummation Notice, as part of the consummation of the Transfer of Common Stock pursuant to the terms and conditions specified in the Transfer Notice and the Consummation Notice. Upon receipt of the proceeds of the Transfer, Thayer shall promptly remit to each Tag Along Stockholder that portion of such proceeds to which such Tag Along Stockholder is entitled by reason of such Stockholder's participation in such Transfer together with any stock certificates for any shares not sold in the Transfer.

Notwithstanding anything to the contrary in this --------------- Article IV, Thayer shall have no obligation to permit a Stockholder, and no - ---------- Stockholder shall have a right, to participate as a Tag Along Stockholder in a Thayer Transfer of Common Stock in the event that such Stockholder's Transfer (i) would not be exempt from all registration requirements under federal and state securities laws or (ii) would violate, or cause Thayer's Transfer to violate, any applicable federal or state laws. ARTICLE V DRAG ALONG RIGHTS 5.1 Drag Along Sale. In the event that, prior to the effective date of an --------------- IPO Event, Thayer, in its sole discretion, determines to accept an offer from a third party that is not an Affiliate of Thayer to purchase all of the Equity Securities then held by Thayer and the Stockholders, then each Stockholder shall be required to sell all the shares of Common Stock and Preferred Stock (together with any other Equity Securities) held by such Stockholder pursuant to such offer (the "Drag Along Sale"). If the Drag Along Sale is structured as a (i) merger or consolidation, each holder of Equity Securities shall waive any dissenters' rights, appraisal rights or similar rights in connection with such merger or consolidation or (ii) sale of stock, each holder of Equity Securities shall agree to sell all of its, her or his Equity Securities and rights to acquire Equity Securities on the terms and conditions approved by the Board and Thayer.

Duong unless such person is then serving as a director of the Company or the Company's Chief Executive Officer or Chief Operating Officer) shall also be required to provide customary representations and warranties regarding the Company. Notwithstanding the foregoing, in the event that any portion of the consideration in a Drag-Along Sale is subject to escrow or a future contingency, each Stockholder's right to the proceeds of the Drag-Along Sale shall be proportionally subject to such escrow and/or contingency and the future payments due therefrom. ARTICLE VI PUBLIC OFFERING Other than the Preferred Stock whose rights and obligations upon the occurrence of an IPO Event shall be determined exclusively by reference to the Company's Amended and Restated Certificate of Incorporation, as amended, in the event that the Board and the holders of a majority of the outstanding shares of Common Stock approve proceeding with an IPO Event, Thayer and the Stockholders shall take all reasonably necessary or desirable actions in connection with the consummation of the IPO Event.
