Notwithstanding anything to the contrary in this subsection 2.l(a), the Corporation shall have no obligation of any kind whatsoever with respect to any request to register Registrable Securities under the Securities Act pursuant to this subsection 2.l(a) unless the aggregate probable gross proceeds to the selling Holders for the number of Registrable Securities requested to be registered for sale to the public pursuant to this 3 subsection 2.l(a) is at least $10,000,000 (as determined by the Board of Directors of the Corporation). (b) Notwithstanding anything to the contrary contained in subsection 2.l(a) above, the Corporation shall not be obligated to prepare or file any registration statement pursuant to subsection 2.l(a) hereof, or to prepare or file any amendment or supplement thereto, at any time when the Corporation, in the good faith judgment of its Board of Directors, reasonably believes that the filing thereof at the time requested, or the offering of Registrable Securities pursuant thereto, (a) would materially adversely affect a pending or proposed public offering of Common Stock, or an acquisition, merger, recapitalization, consolidation, reorganization or similar transaction, or any negotiations, discussions or pending proposals with respect thereto or (b) would materially adversely affect the business or prospects of the Corporation in view of the disclosures that may be required thereby of information about the business, assets, liabilities or operations of the Corporation not theretofore disclosed; PROVIDED, HOWEVER, that the filing of a registration statement, or any supplement or amendment thereto, by the Corporation may be deferred pursuant to this subsection 2.l(b) for no longer than (i) if such deferment is pursuant to clause (a) above, 60 calendar days after the abandonment or consummation of any of the foregoing proposals or transactions or (ii) if such deferment is pursuant to clause (b) above, 60 calendar days beyond the time-requested. (c) The Corporation shall be entitled to include in any registration statement filed or to be filed by the Corporation pursuant to subsection 2.l(a) above shares of Common Stock to be sold by the Corporation for its own account. If any offering pursuant to subsection 2.l(a) above shall be in the form of an underwritten offering, and the managing underwriter or underwriters of such offering, in good faith, advise the Corporation and the selling Preferred Holders in writing that in its or their opinion the aggregate amount of shares of Common Stock requested to be included in such offering (including the Registrable Securities, any shares of Common Stock to be offered for the account of the Corporation and any shares of Common Stock to be offered for the account of any other security holders of the Corporation) would materially adversely affect the success of such offering or the price of the shares of Common Stock to be offered, then the Corporation shall reduce the number of shares of Common Stock to be included in such offering to the amount of Common Stock which the managing underwriter or underwriters have advised can be sold in such offering, said reduction to be effected in the following order: (x) first, any or all shares of Common Stock requested to be included in such offering by such other security holders of the Corporation, PRO RATA among such other stockholders in proportion to the number of shares of Common Stock sought to be registered by such other security holders, (y) second, any or all shares of Common Stock to be sold by the Corporation pursuant to such offering, and (z) third, any or all Registrable Securities requested to be included in such offering by the Holders, PRO RATA among the Holders in proportion to the respective number of Registrable Securities sought to be registered by the selling Preferred Holders. The Preferred Holders proposing to distribute Registrable Securities through such underwriting shall enter into an underwriting agreement in customary form with the managing underwriter selected for such underwriting by mutual agreement of the Corporation and the Required Preferred 4 Holders. If any selling Preferred Holder disapproves of the terms of the underwriting, such person may elect to withdraw therefrom by written notice to the Corporation and the managing underwriter or underwriters. The Registrable Securities so withdrawn shall also be withdrawn from registration. (d) Notwithstanding anything in this subsection 2.1 to the contrary, the Corporation shall not be required to consummate more than one offering of Registrable Securities pursuant to subsection 2.l(a) above. 2.2 PIGGYBACK REGISTRATION. If at any time after the Initial Public Offering, the Corporation proposes to file a registration statement under the Securities Act covering a proposed sale of its Common Stock, whether for its own account or for the account of any other security holder or both (other than a registration statement on Form S-4 or S-8, or any form substituting therefor for shares of Common Stock to be offered in a transaction of the type referred to in Rule 145 under the Securities Act or to employees of the Corporation pursuant to any employee benefit plan, respectively, and other than a registration statement filed in connection with an offering effected pursuant to subsection 2.l(a) or 2.3(a) hereof), the Corporation shall give each Holder written notice of such proposed filing at least 20 Business Days prior to the anticipated filing date, and such notice shall offer each such Holder the opportunity to register such number of Registrable Securities as they may request, which request must be delivered to the Corporation in writing within ten Business Days after the notice given by the Corporation. The Corporation shall use its best efforts to cause the Registrable Securities as to which registration shall have been so requested by the requesting Holders to be included among the shares of Common Stock to be covered by the registration statement proposed to be filed by the Corporation pursuant to this subsection 2.2. In the event that any such registration statement shall be, in whole or in part, an underwritten public offering, the Corporation shall use its best efforts to cause the managing underwriter or underwriters to include such Registrable Securities as to which registration shall have been so requested by the requesting Holders, all upon the same terms and conditions as the other shares of Common Stock included therein. Notwithstanding the foregoing, if the managing underwriter or underwriters of such offering, in good faith, determine that the total number of shares of Common Stock which the requesting Holders, the Corporation and any other security holders of the Corporation intend to include in such offering would materially adversely affect the success of such offering or the price of the shares of Common Stock to be offered, then the Corporation shall reduce the number of shares of Common Stock to be included in such offering to the number of shares of Common Stock which the managing underwriter or underwriters shall have advised can be sold in such offering, said reduction to be effected in the following order: (x) first, any or all shares of Common Stock requested to be included in such offering by any other security holders of the Corporation (other than security holders exercising demand registration rights), pro rata among such other security holders in proportion to their respective numbers of shares of Common Stock sought to be registered pursuant to such offering, (y) second, any or all shares of Common Stock requested to be included in such offering by the Holders, pro rata among the Holders in proportion to their respective number of Registrable Securities sought to be registered pursuant to such offering, (z) third, any or all shares of Common 5 Stock proposed to be sold by the Corporation pursuant to such offering, and (zz) fourth, any or all shares of Common Stock requested to be included in such offering by security holders of the Corporation exercising demand registration rights, PRO RATA among such security holders in proportion to the number of shares of Common Stock entitled to be registered by each and in accordance with their respective priorities. In the event that the contemplated registration does not involve an underwritten public offering, the determination that the inclusion of any Registrable Securities requested to be included in such registration by the requesting Holders would have a material adverse effect on the success of such offering or the price of the shares of Common Stock to be offered shall be made in the good faith reasonable judgment of the Corporation's Board of Directors. 2.3 S-3 REGISTRATIONS. (a) Subject to the limitations and provisions set forth in this subsection 2.3(a) and in subsections 2.3(b) and 2.3(c) below, at any time from and after the first anniversary of the closing of the Initial Public Offering, Holders shall have the right to require the Corporation to file a registration statement on Form S-3, if available, or any comparable or successor form, under the Securities Act for purposes of registering for sale to the public Registrable Securities representing probable gross proceeds to the selling Holders of at least $1,000,000 (the "Minimum S-3 Registrable Securities Amount"), the amount of such probable gross proceeds to be determined in good faith by the Board of Directors of the Corporation. The Holders may exercise their rights under this Section 2.3 by notifying the Corporation in writing that they desire for the Corporation to cause all or a portion of such Holders' Registrable Securities (but in no event less than the Minimum S-3 Registrable Securities Amount) to be registered for sale to the public under the Securities Act pursuant to this subsection 2.3(a); PROVIDED, HOWEVER, that the Holders shall not be entitled to request that the Corporation register Registrable Securities for sale to the public pursuant to this Section 2.3 at any time within one year after the effective date of a registration statement filed by the Corporation in connection with a public offering in which the Holders shall have been entitled to join pursuant to this subsection 2.3(a) or subsections 2.1 or 2.2 hereof. Upon receipt of such written request by any of the Holders, the Corporation shall promptly notify in writing all other Holders of such request, and such other Holders shall have a period of ten Business Days following such notice from the Corporation to notify the Corporation in writing whether such other Holders, or any of them, desire to have Registrable Securities held by them registered for sale to the public under the Securities Act pursuant to this subsection 2.3(a). Thereafter, subject to the conditions, limitations and provisions set forth below in this subsection 2.3(a) or in subsections 2.3(b) and 2.3(c) hereof, the Corporation shall, promptly following the expiration of such ten Business Day period, prepare and file, and use its best efforts to prosecute to effectiveness, a registration statement on Form S-3 (or any comparable or successor form) covering all of those Registrable Securities (but in no event less than the Minimum S-3 Registrable Securities Amount) of the Holders with respect to which registration under the Securities Act has been requested pursuant to this subsection 2.3(a). Notwithstanding anything expressed or implied in this subsection 2.3(a) to the contrary, any offering pursuant to this subsection 2.3(a) shall not be in the form of an underwritten offering. 6 (b) Notwithstanding anything to the contrary contained in subsection 2.3(a) above, the Corporation shall not be obligated to prepare or file any registration statement pursuant to subsection 2.3(a) hereof, or to prepare or file any amendment or supplement thereto, at any time when the Corporation, in the good faith judgment of its Board of Directors, reasonably believes that the filing thereof at the time requested, or the offering of Registrable Securities pursuant thereto, (a) would materially adversely affect a pending or proposed public offering of Common Stock, or an acquisition, merger, recapitalization, consolidation, reorganization or similar transaction, or any negotiations, discussions or pending proposals with respect thereto or (b) would materially adversely affect the business or prospects of the Corporation in view of the disclosures that may be required thereby of information about the business, assets, liabilities or operations of the Corporation not theretofore disclosed; PROVIDED, HOWEVER, that the filing of a registration statement, or any supplement or amendment thereto, by the Corporation may be deferred pursuant to this subsection 2.3(b) for no longer than (i) if such deferment is pursuant to clause (a) above, 60 calendar days after the abandonment or consummation of any of the foregoing proposals or transactions or (ii) if such deferment is pursuant to clause (b) above, 60 calendar days beyond the time-requested. (c) Notwithstanding anything in this subsection 2.3 to the contrary, the Corporation shall not be required to consummate more than three offerings of Registrable Securities pursuant to subsection 2.3(a) above. The Corporation shall be entitled to include in any registration statement filed or to be filed by the Corporation pursuant to subsection 2.3(a) above shares of Common Stock to be sold by the Corporation for its own account. 2.4 FURTHER OBLIGATIONS OF THE CORPORATION. Whenever, under this Agreement, the Corporation is required to register Registrable Securities, it agrees that it shall also do the following: (a) prepare and file with the Commission a registration statement with respect to such Registrable Securities and use its best efforts to cause such registration statement to become and remain effective for a period of time required for the disposition of such Registrable Securities by the Holders thereof provided that such period shall not be longer than six months from the date of such registration statement unless the Corporation otherwise agrees in its sole discretion; (b) prepare and file with the Commission such amendments and supplements to such registration statement and the prospectus used in connection therewith as may be necessary to keep such registration statement effective; (c) furnish to each Holder offering Registrable Securities under such registration statement such number of copies of a summary prospectus or other prospectus, including a preliminary prospectus complying with the requirements of the Securities Act, as such Holder may reasonably request; and 7 (d) register or qualify the Registrable Securities covered by such registration statement under the securities or blue sky laws of such jurisdictions within the United States and Puerto Rico as the underwriter or manager shall request or in the event that the registration does not involve an underwritten public offering as each such Holder shall reasonably request; PROVIDED that the Corporation shall not be obligated to register or qualify such Registrable Securities in any jurisdiction in which such registration or qualification would require the Corporation to qualify as a foreign corporation or file any general consent to service of process where it is not then so qualified or otherwise required to be qualified or has not theretofore so consented. 2.5 HOLDBACK AGREEMENT. In connection with the Initial Public Offering and any registration in which any Holder is participating in connection with an underwritten public offering, each Preferred Holder agrees (and shall enter into an agreement which shall so state), if requested by the managing underwriter or underwriters, not to effect any public sale or distribution, including any sale pursuant to Rule 144 under the Securities Act, of any shares of Common Stock or any other equity security of the Corporation or of any security convertible into or exchangeable or exercisable for Common Stock or any such other equity security of the Corporation (in each case, other than as part of such underwritten public offering) within ten days before or 180 days after the effective date of the registration statement filed in connection with such underwritten offering; provided that all officers and directors of the Corporation and all other persons with registration rights (whether or not pursuant to this Agreement) enter into similar agreements. 2.6 EXPENSES; CERTAIN CONDITIONS TO REGISTRATION.

(a) INDEMNIFICATION BY THE CORPORATION. In the event of any registration of any Registrable Securities under the Securities Act pursuant to this Agreement, the Corporation shall indemnify and hold harmless each Holder of such Registrable Securities, such Holder's directors, officers, employees and agents, each underwriter who participated in the offering of such Registrable Securities and each other Person, if any, who controls such Holder or such underwriter within the meaning of the Securities Act, against any losses, claims, damages, liabilities or expenses, joint or several, to which such Holder or any such director, officer, employee or agent or underwriter or controlling Person may become subject under the Securities Act or any other statute or at common law, insofar as such losses, claims, damages, liabilities or expenses (or actions in respect thereof) arise out of or are based upon (i) any untrue statement or alleged untrue statement of any material fact contained, on the effective date thereof, in any registration statement under which such Registrable Securities were registered under the Securities Act, any preliminary prospectus or final prospectus contained therein, or any amendment or supplement thereto, or (ii) any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and shall reimburse such Holder or such director, officer, employee or agent or underwriter or controlling Person for any legal or any other expenses reasonably incurred by such Holder or such director, officer, employee or agent or underwriter or controlling Person in connection with investigating or defending, settling or satisfying any such loss, claim, damage, liability, expense or action; provided, however, that the Corporation shall not be liable in any such case to the extent that any such loss, claim, damage, liability or expense arises out of or is based upon any untrue statement or alleged untrue statement or any omission or alleged omission made in such registration statement, preliminary prospectus, or amendment or supplement in reliance upon and in conformity with written information furnished to the Corporation by such Holder specifically for use therein. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of such Holder or such director, officer, employee or agent or underwriter or controlling Person, and shall survive the transfer of such Registrable Securities by such Holder. (b) HOLDERS' INDEMNIFICATION. In connection with any registration statement in which a Holder is participating, each such Holder will furnish to the Corporation in writing such information as shall reasonably be requested by the Corporation for use in any such registration statement or prospectus and shall severally, but not jointly, indemnify, to the extent permitted by law, the Corporation, its directors, officers, employees and agents, each underwriter and each Person, if any, who controls the Corporation or such underwriter within the meaning of the Securities Act (collectively, 9 the "Indemnitees"), against any losses, claims, damages, liabilities and expenses (under the Securities Act, at common law or otherwise) caused by or resulting from any untrue statement or alleged untrue statement of a material fact contained in any registration statement filed by the Corporation under the Securities Act, or any prospectus or preliminary prospectus included therein (in each case as amended or supplemented), or caused by any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, but only to the extent that such untrue statement of a material fact is contained in, or such material fact is omitted from, information furnished in writing by such Holder for use therein, and such Holder shall reimburse the Indemnitees for any legal and any other expenses reasonably incurred in connection with investigating or defending, settling or satisfying any such loss, claim, damage, liability or expense. Notwithstanding anything herein to the contrary, a Holder's obligation to indemnify the Indemnitees shall be limited to the amount of money such Holder received in connection with the sale of Registrable Securities under such registration statement. (c) CONTRIBUTION. If the indemnification provided for in this subsection 2.7 from the indemnifying party (which term shall, for purposes of this subsection 2.7, include all indemnifying parties if there be more than one) is unavailable to an indemnified party hereunder in respect of any losses, claims, damages, liabilities or expenses referred to herein, then the indemnifying party, in lieu of indemnifying such indemnified party, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages, liabilities or expenses in such proportion as is appropriate to reflect the relative fault of the indemnifying party and indemnified parties in connection with the actions which resulted in such losses, claims, damages, liabilities or expenses, as well as any other relevant equitable considerations. The relative fault of such indemnifying party and indemnified parties shall be determined by reference to, among other things, whether any action in question, including any untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact, has been made by, or relates to information supplied by, such indemnifying party or indemnified parties, and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such action. The amount paid or payable by a party under this subsection 2.7(c) as a result of the losses, claims, damages, liabilities and expenses referred to above shall be deemed to include any legal or other fees or expenses reasonably incurred by such party in connection with any investigation or proceeding. The parties hereto agree that it would not be just and equitable if contribution pursuant to this subsection 2.7(c) were determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to in the immediately preceding paragraph. Notwithstanding the provisions of this subsection 2.7(c), no Holder shall be required to contribute any amount in excess of the total amount received by it upon the sale of its Registrable Securities pursuant to any registration statement to which the losses, claims, damages, liabilities and expenses referred to above relate. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The obligations of each 10 of the Holders under this subsection 2.7(c) to contribute are several and not joint. (d) INDEMNIFICATION PROCEDURES. Promptly after receipt by an indemnified party hereunder of notice of the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party hereunder, notify the indemnifying party in writing thereof, but the omission so to notify the indemnifying party shall not relieve it from any liability which it may have to any indemnified party. In case any such action shall be brought against any indemnified party and it shall notify the indemnifying party of the commencement thereof, the indemnifying party shall be entitled to participate in and, to the extent it shall wish, to assume and undertake the defense thereof with counsel reasonably satisfactory to such indemnified party, and, after notice from the indemnifying party to such indemnified party of its election so to assume and undertake the defense thereof, the indemnifying party shall not be liable to such indemnified party under this subsection 2.7(d) for any legal expenses subsequently incurred by such indemnified party in connection with the defense thereof other than reasonable costs of investigation and of liaison with counsel so selected; PROVIDED, HOWEVER, that, if the defendants in any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that there may be reasonable defenses available to it which are different from or additional to those available to the indemnifying party, or if the interests of the indemnified party reasonably may be deemed to conflict with the interest of the indemnifying party, the indemnified party shall have the right to select a separate counsel and to assume such legal defenses and otherwise to participate in the defense of such action, with the expenses and fees of such separate counsel and other expenses related to such participation to be reimbursed by the indemnifying party as incurred. 2.8 TERMINATION OF REGISTRATION RIGHTS. (a) The right of any Holder to request registration or inclusion in any registration pursuant to any provision of Section 2 of this Agreement shall terminate on such date after the closing of the Initial Public Offering as all shares of Registrable Securities beneficially owned or subject to Rule 144 aggregation by such Holder may immediately be sold under Rule 144 (without regard to Rule 144(k)) during any 90-day period; provided, however, that the provisions of this subsection 2.8(a) shall not apply to any Holder who owns more than two percent (2%) of the Corporation's outstanding stock until such time as such Holder owns less than two percent (2%) of the outstanding stock of the Corporation. (b) This Agreement and all of the rights of Holders granted hereunder shall terminate on the sixth (6th) anniversary of the date hereof. 2.9 ASSIGNMENT OF REGISTRATION RIGHTS.
