-5-

planned initial filing date of such Registration Statement. Subject to reduction pursuant to Section 5(a), such Registration Statement shall cover the Registrable Common Shares requested by the Initiating Demand Holders to be registered and such other Registrable Common Shares as the Holders other than the Initiating Demand Holders shall request, by written notice to the Company given no later than five Business Days prior to such planned initial filing date, to be registered.

(b) Notwithstanding the provisions of Section 3(a), the Company shall not be required to take any action pursuant to this Section 3:

(i) if prior to the date of a request pursuant to Section 3(a), the Company shall have effected four registrations pursuant to Section 3(a);

(ii) if the Company shall have effected a registration pursuant to this Section 3 within the 120-day period immediately preceding the date of such request which permitted Holders to register Registrable Common Shares;

(iii) if the Registrable Common Shares which the Company shall have been requested to register shall have an aggregate offering price of less than $5,000,000, unless such registration request is for all remaining Registrable Common Shares held by the Holders; or

(iv) during the pendency of any Blackout Period;

provided, however, that the Company shall be permitted to satisfy its obligations under Section 3(a) by amending (to the extent permitted by applicable law) within 30 days after a written request for registration, any Registration Statement previously filed by the Company under the Securities Act so that such Registration Statement (as amended) shall permit the disposition (in accordance with the intended methods of disposition, including, without limitation, an Underwritten Offering, specified by the Holders as aforesaid) of all of the Registrable Common Shares for which a demand for registration has been made under Section 3(a). If the Company shall so amend a previously filed Registration Statement, it shall be deemed to have effected a registration for purposes of this Section 3.

(c) The Holders delivering a request pursuant to Section 3(a) may distribute the Registrable Common Shares covered by such demand by means of an Underwritten Offering or any other method of distribution, as determined by the Holders holding a Majority of the Registrable Common Shares so requested to be registered by all Holders.

(d) Subject to Section 3(e), a registration requested pursuant to this Section 3 shall not be deemed to be effected for purposes of this Section 3: (i) if the Registration Statement for such registration has not been declared effective by the SEC or become effective in accordance with the Securities Act and the rules and regulations thereunder; (ii) in the case of a Registration Statement which does not contemplate an Underwritten Offering, if such Registration Statement does not remain effective for at least 120 days (or such shorter period that will terminate when all Registrable Common Shares covered by such Registration Statement have been sold or withdrawn); (iii) in the case of a Registration Statement which contemplates an Underwritten Offering, if (A) such Registration Statement does not remain

-6-

effective for at least 120 days plus such longer period (not to exceed 90 days after the 120^th day) as, in the opinion of counsel for the underwriter or underwriters, is required by law for the delivery of a Prospectus in connection with the sale of Registrable Common Shares by an underwriter or dealer, or (B) the conditions to closing specified in the applicable underwriting agreement are not satisfied by reason of a violation or breach of such underwriting agreement or this Agreement by the Company; or (iv) if, as a result of a determination made by the lead managing underwriter or (if the offering shall not be an Underwritten Offering) the Holders pursuant to Section 5(a), the Holders shall not be entitled to include in such registration at least 75% of the Registrable Common Shares that such Holders requested pursuant to Section 3(a) to be so included in such registration.

(e) Holders holding a Majority of the Registrable Common Shares held by all Holders to be included in a Registration Statement to be filed pursuant to Section 3(a) may, at any time prior to the effective date of the Registration Statement relating to such registration, revoke such request by providing a written notice to the Company revoking such request. The Company shall be deemed to have effected a registration pursuant to Section 3(a) in the case of any such revocation of an offering initiated by the Initiating Demand Holders, unless (i) the revocation is based on a reasonable determination, made by Holders holding a Majority of the Registrable Common Shares held by all Holders to be included in such Registration Statement, that there has been, since the date of the applicable request pursuant to Section 3(a), a material adverse change in the business, financial condition, results of operations or prospects of the Company, in general market conditions or in market conditions for businesses in the Company’s industry generally or (ii) the Holders requesting that Registrable Common Shares be included in such registration reimburse the Company for all Registration Expenses incurred by the Company with respect to such revoked request. Except as otherwise contemplated by clause (ii) of the immediately preceding sentence, no revocation pursuant to this Section 3(e) shall relieve the Company of its obligation hereunder to pay the Registration Expenses in connection with any such request.

4. Piggy-Back Registration Rights.

(a) If, during the Registration Rights Period, the Company shall propose to file a Registration Statement under the Securities Act relating to a public offering of Common Stock or other securities (other than in connection with an Excluded Registration or a Registration Statement filed pursuant to Section 3 of the Series A Registration Rights Agreement) for the Company’s own account or for the account of any holder or holders of Common Stock or other securities (including, without limitation, any Series A Preferred Stockholder or any WCAS Securityholder) pursuant to the exercise of registration rights (each such Person or Persons for whose account such a Registration Statement is proposed to be filed, an “Initiating Securityholder”), in each case, on a registration form and in a manner that would permit the registration of Registrable Common Shares for sale to the public under the Securities Act, the Company shall (x) give written notice at least 15 Business Days prior to the filing thereof to each Holder, specifying the approximate date on which the Company proposes to file such Registration Statement and advising such Holder of its right to have any or all of the Registrable Common Shares of such Holder included among the securities to be covered thereby, and (y) at the written request of any such Holder given to the Company within 15 Business Days after written notice from the Company has been given to the Holder,

-7-

include among the securities covered by such Registration Statement the number of Registrable Common Shares which such Holder (a “Requesting Holder”) shall have requested be so included (subject, however, to reduction, in accordance with the applicable provisions of Section 5).

(b) Nothing in this Section 4 shall create any liability on the part of the Company to any Holder of Registrable Common Shares if for any reason the Company shall decide not to file, or to delay the filing of, a Registration Statement proposed to be filed under Section 4(a) or to withdraw such Registration Statement subsequent to its filing, regardless of any action whatsoever that a Holder may have taken, whether as a result of the issuance by the Company of any notice hereunder or otherwise, provided, however, that the Company shall not be relieved of its obligation hereunder to pay the Registration Expenses in connection with any such filing or proposed filing.

(c) Any Holder participating in an Underwritten Offering by the Company for its own account may, at its option, require that any or all of the representations and warranties by, and the other agreements on the part of, the Company to and for the benefit of the underwriters of such Underwritten Offering shall also be made to and for the benefit of such Holder and that any or all of the conditions precedent to the obligations of such underwriters under the underwriting agreement for such Underwritten Offering shall also be conditions precedent to the obligations of such Holder, in each case to the extent that such agreements and conditions precedent shall reasonably be applicable to selling stockholders in addition to such underwriters.

In connection with the inclusion of Registrable Common Shares pursuant to Section 4(a) in any such offering by the Company, if the lead managing underwriter in an Underwritten Offering delivers a Cutback Notice to the Company (it being understood that the Company shall as soon as reasonably practicable deliver copies of any such notice to all Holders who have requested to include Registrable Common Shares in such offering) or (if the offering shall not be an Underwritten Offering) the Company delivers a Cutback Notice to the Holders, then the Company shall include in such offering, in addition to the securities the Company proposes to sell for its own account,

-10-

WCAS Securityholders to be included in such offering, calculated on an as-converted basis assuming that all of the Series A Registrable Securities of the Series A Preferred Stockholders and all of the WCAS Registrable Securities of the WCAS Securityholders requested to be so included that are convertible into or exercisable for Common Stock are converted into or exercised for Common Stock as of such date), (ii) second, the number, if any, of shares of Common Stock or other securities the Company proposes to sell for its own account that, in the reasonable and good faith opinion of such lead managing underwriter or the Initiating Securityholders, as applicable, can be sold without having an Adverse Offering Effect, and (iii) third, the number, if any, of other shares of Common Stock and other securities requested to be included in such offering that, in the reasonable and good faith opinion of such lead managing underwriter or the Initiating Securityholders, as applicable, can be sold without having an Adverse Offering Effect, such other shares of Common Stock and other securities to be allocated among the holders thereof who have requested that their shares and other securities be so included in accordance with the provisions of their registration rights agreements with the Company.

7. Blackout Periods; Holdback.

(a) If the Company determines that the registration and distribution of Registrable Common Shares (i) would materially impede, delay, interfere with or otherwise adversely affect any pending financing, registration of securities by the Company in a primary offering for its own account, acquisition, corporate reorganization or other significant transaction involving the Company or (ii) would require disclosure of non-public material information that the Company has a bona fide business purpose for preserving as confidential, as determined by the Company’s Board of Directors in good faith, the Company shall be entitled to defer the filing or effectiveness of a Registration Statement, or to suspend the use of an effective Registration Statement, for the shortest period of time reasonably required (each such period, a “Blackout Period”); provided that the Company shall not be entitled to obtain deferrals or suspensions under (x) clause (i) of this Section 7(a), for more than an aggregate of 90 days in any 12-month period or (y) clause (ii) of this Section 7(a), for more than 30 days on any one occasion, on more than two occasions in any 12-month period or for more than an aggregate of 60 days in any 12-month period. The Company shall notify each Holder of the expiration or earlier termination of a Blackout Period and, as soon as reasonably practicable after such expiration or termination, shall amend or supplement any effective Registration Statement to the extent necessary to permit the Holders to resume use

If requested by such managing underwriter, each Holder shall enter, and shall use commercially reasonable efforts to ensure that all Affiliates (other than any Affiliates of such Holder that are portfolio companies of such Holder or of any investment funds that are Affiliates of such Holder) of such Holder holding Registrable Common Shares or Similar Securities enter, into a lock-up agreement with the applicable underwriters that is consistent with the agreement in the preceding sentence.

(c) Notwithstanding any provision of Section 7(a) or 7(b) to the contrary, the cumulative period of any Blackout Periods pursuant to Section 7(a) and of any holdbacks pursuant to Section 7(b) shall not exceed, in the aggregate, 97 days in any 12-month period.

(d) In the case of any Underwritten Offering of Registrable Common Shares initiated by a Holder pursuant to Section 3, the Company agrees, if requested by the lead managing underwriter of such Underwritten Offering, not to effect (or register for sale) any public sale or distribution of any securities which are Similar Securities for the Company’s own account during the period beginning seven days before, and ending 90 days (or such lesser period as may be permitted by such lead managing underwriter) after, the effective date of the Registration Statement filed in connection with such registration, except for securities of the Company to be offered for the Company’s account in such Underwritten Offering. Notwithstanding the foregoing, the Company may effect a public sale or distribution of Common Stock and other securities which are Similar Securities for the Company’s own account during the period described above (A) pursuant to registrations on Forms S-4 or S-8 or any successor registration forms or (B) as part of any registration of securities for offering and sale to employees, directors or consultants of the Company pursuant to any stock plan or other benefit plan arrangement. The Company agrees to use commercially reasonable best efforts to obtain from each director or executive officer of the Company who holds Similar Securities an agreement not to effect any public sale or distribution of such Similar Securities (other than any sale under Rule 144 or Rule 145) for the account of such director or executive officer during any period referred to in this Section 7(d), except as part of any Underwritten Offering contemplated in this Section 7(d).

8. Registration Procedures. In connection with the registration obligations of the Company under Sections 3 and 4, the Company shall:

(a) prepare and file with the SEC a Registration Statement with respect to such Registrable Common Shares on any registration form adopted by the SEC for which the Company then qualifies or which counsel for the Company shall deem appropriate, and which form shall be available for the sale of the Registrable Common Shares in accordance with the intended methods of distribution thereof, and use reasonable best efforts to cause such Registration Statement to become and remain effective; provided that, at least five Business Days prior to filing a Registration Statement or Prospectus or any amendment or supplement thereto, the Company shall furnish to a single counsel selected by the Holders of a Majority of the Registrable Common Shares included or to be included in such Registration Statement copies of such Registration Statement or Prospectus (or amendment or supplement) as proposed to be filed (including, upon the request of such counsel, documents to be incorporated by reference therein) which documents shall be subject to the reasonable review and comments of such counsel and the Holders of the Registrable Common Shares included or to be included in such Registration Statement during such five-Business-Day period, and the Company shall not file any Registration Statement, any Prospectus or any amendment or supplement thereto (or any such documents incorporated by reference) containing any statements with respect to any such Holder to which such Holder shall reasonably object in writing;

(b) prepare and file with the SEC amendments and post-effective amendments to such Registration Statement and such amendments and supplements to the Prospectus used in connection therewith as may be necessary to maintain the effectiveness of such registration or as may be required by the rules, regulations or instructions applicable to the registration form utilized by the Company or by the Securities Act or rules and regulations thereunder necessary to keep such Registration Statement effective until the earlier of (i) the date on which the Registrable Common Shares covered by such Registration Statement cease to be Registrable Common Shares or have been sold or withdrawn and (ii) subject to Sections 8(e) and 8(k), (x) in the case of a Registration Statement filed pursuant to Section 3 which does not contemplate an Underwritten Offering, for at least 120 days or (y) in the case of a Registration Statement filed pursuant to Section 3 which contemplates an Underwritten Offering, for at least 120 days plus such longer period (not to exceed 90 days after the 120^th day) as, in the opinion of counsel for the underwriter or underwriters of such Underwritten Offering, is required by law for the delivery of a Prospectus in connection with the sale of Registrable Common Shares by an underwriter or dealer, and cause the Prospectus as so amended and supplemented to be filed pursuant to Rule 424 under the Securities Act, and otherwise use reasonable best efforts to comply with the provisions of the Securities Act with respect to the disposition of all securities covered by such Registration Statement until such time as is specified in clause (i) or (ii) above, as the case may be;

-13-

(d) use reasonable best efforts to register or qualify such Registrable Common Shares covered by such Registration Statement under such other securities or blue sky laws of such jurisdictions as each Holder shall reasonably request, and to do any and all other acts and things which may be reasonably necessary to enable such Holder to consummate the disposition in such jurisdictions of the Registrable Common Shares owned by such Holder, except that the Company shall not be required for any such purpose to qualify generally to do business as a foreign corporation in any jurisdiction where, but for the requirements of this Section 8(d), it would not be obligated to be so qualified, to subject itself to taxation in any such jurisdiction, or to consent to general service of process in any such jurisdiction;

(e) promptly notify each Holder of any such Registrable Common Shares covered by such Registration Statement, at any time when a Prospectus relating thereto is required to be delivered under the Securities Act within the applicable period referred to in Section 8(b), that the Company has become aware that the Prospectus included in such Registration Statement, as then in effect, includes an untrue statement of material fact or omits to state a material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances then existing (the period during which the Holders are required in such case pursuant to Section 9(b) to refrain from effecting public sales or distributions of Registrable Common Shares referred to herein as a “Section 8(e) Period”), and prepare and furnish to such Holder, as soon as reasonably practicable, without charge to such Holder, a reasonable number of copies of an amendment to such Registration Statement or supplement to such related Prospectus as may be necessary so that, as thereafter delivered to the purchasers of such Registrable Common Shares, such Prospectus shall not include an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances then existing; provided that if the Company gives such notice, the Company shall extend the period during which such Registration Statement shall be maintained effective (including the periods referred to in Section 8(b)) by the number of days in the Section 8(e) Period;

(i) make such representations and warranties to the underwriters in form, substance and scope as are customarily made by issuers to underwriters in comparable Underwritten Offerings;

(ii) use reasonable best efforts to obtain opinions of counsel to the Company (in form, scope and substance reasonably satisfactory to the managing underwriters), addressed to the underwriters, and covering the matters customarily covered in opinions requested in comparable Underwritten Offerings;

(iii) use reasonable best efforts to obtain “cold comfort” letters and bring-downs thereof from the Company’s independent certified public accountants addressed to the underwriters, such letters to be in customary form and covering matters of the type customarily covered in “cold comfort” letters by independent accountants in connection with Underwritten Offerings; and

(iv) deliver such documents and certificates as may be reasonably requested by the managing underwriters to evidence compliance with any customary conditions contained in the underwriting agreement;

(i) cooperate with the Holders of Registrable Common Shares covered by such Registration Statement and the managing underwriter or underwriters or agents, if any, to facilitate the timely preparation and delivery of certificates (not bearing any restrictive legends) representing the securities to be sold under such Registration Statement, and enable such securities to be in such denominations and registered in such names as the managing underwriter or underwriters or agents, if any, or such Holders, may request;

(j) if reasonably requested by the managing underwriter or underwriters or a Holder of Registrable Common Shares being sold in connection with an Underwritten Offering, incorporate in a Prospectus supplement or post-effective amendment to the Registration Statement such information as the managing underwriters and the Holders of a Majority of the Registrable Common Shares being sold by all Holders agree should be included therein relating to the plan of distribution with respect to such Registrable Common Shares, including, without limitation, information with respect to the amount of Registrable Common Shares being sold to such underwriters, the purchase price being paid therefor by such underwriters and any other terms of the Underwritten Offering of the Registrable Common Shares to be sold in such offering and make all required filings of such Prospectus supplement or post-effective amendment upon being notified of the matters to be incorporated in such Prospectus supplement or post-effective amendment;

-15-

(k) in the event of the issuance of any stop order of which the Company is aware suspending the effectiveness of the Registration Statement, or of any order suspending or preventing the use of any related Prospectus or suspending the qualification of any Registrable Common Shares included in the Registration Statement for sale in any jurisdiction, use reasonable best efforts to obtain at the earliest practicable time the withdrawal of such stop order or other order (the period between the issuance and withdrawal of any stop order or other order referred to herein as a “Section 8(k) Period”); provided that the Company shall extend the period during which such Registration Statement will be maintained effective (including the periods referred to in Section 8(b)) by the number of days in the Section 8(k) Period;

(l) use reasonable best efforts to cause all Common Stock covered by such Registration Statement to be listed on any securities exchange or automated quotation system on which the Common Stock is then listed, if such Common Stock is not already so listed and if such listing is then permitted under the rules of such securities exchange or automated quotation system;

(m) in the case of an Underwritten Offering, cause the senior executive officers of the Company to participate in the customary “road show” presentations that may be reasonably requested by the lead managing underwriter in any such Underwritten Offering and otherwise to cooperate with and participate in customary selling efforts related thereto;

(o) provide and cause to be maintained a transfer agent and registrar for all Registrable Common Shares covered by the applicable Registration Statement from and after a date not later than the effective date of such Registration Statement;

(p) make available upon reasonable notice at reasonable times and for reasonable periods for inspection by one representative appointed by the Holders of a Majority of the Registrable Common Shares covered by the applicable Registration Statement, by any managing underwriter or underwriters participating in any Underwritten Offering to be effected pursuant to such Registration Statement, and by any attorney, accountant or other agent retained by such Holders or any such managing underwriter, all pertinent financial and other records, pertinent corporate documents and properties of the Company, and cause all of the Company’s officers, directors and employees and the independent public accountants who have certified its financial statements to make themselves available during normal business hours to discuss the business of the Company and to supply all information reasonably requested by any such Holders or managing underwriter or agent thereof in connection with such Registration Statement as shall be necessary to enable such Persons to exercise their due diligence responsibility (subject to the

-16-

entry by each Person referred to in this Section 8(p) into customary confidentiality agreements in a form reasonably acceptable to the Company);

(q) if requested in writing by Holders holding a Majority of the Registrable Common Shares included in such Registration Statement, prepare and file with the SEC amendments and post-effective amendments to such Registration Statement and amendments and supplements to the Prospectus used in connection with such Registration Statement as shall be necessary to enable any transferee of Registrable Common Shares included in such Registration Statement who becomes a Holder under this Agreement to resell such Holder’s Registrable Common Shares pursuant to such Registration Statement, to the extent that such amendments, post-effective amendments and supplements shall be required for such transferee- Holders to be named as selling securityholders in such Registration Statement and Prospectus; and

(r) use reasonable best efforts to take all other steps necessary to effect the registration of the Registrable Common Shares contemplated hereby.

9. Agreements of Holders.

(a) As a condition to the Company’s obligation under this Agreement to cause Registrable Common Shares of any Holder to be included in a Registration Statement, such Holder shall timely provide the Company with all of the information required to be provided in the Registration Statement with respect to such Holder pursuant to Items 507 and 508 of Regulation S-K under the Securities Act and such other information as otherwise may reasonably be requested by the Company in connection with the Registration Statement.

(b) Each Holder shall comply with the prospectus delivery requirements of the Securities Act in connection with the offer and sale of Registrable Common Shares made by such Holder pursuant to any Registration Statement. Upon receipt of any notice from the Company of the happening of any event of the kind described in Section 8(e) or Section 8(k), each Holder of Registrable Common Shares shall forthwith discontinue the disposition of Registrable Common Shares pursuant to the Prospectus or Registration Statement covering such Registrable Common Shares until such Holder’s receipt of the copies of the supplemented or amended Prospectus contemplated by Section 8(e) or the withdrawal of any stop order or other order referred to in Section 8(k), and, if so directed by the Company, shall deliver to the Company all copies, other than permanent file copies then in such Holder’s possession, of the Prospectus covering such Registrable Common Shares at the time of receipt of such notice.

(c) To the extent required by the Securities Act or rules or regulations thereunder, as reasonably determined by the Company, a Holder shall consent to disclosure in any Registration Statement to the effect that such Holder is or may be deemed to be an underwriter for purposes of the Securities Act in connection with the offering of Registrable Common Shares of such Holder included in such Registration Statement.

(d) Each Holder shall comply with Regulation M under the Exchange Act in connection with the offer and sale of Registrable Common Shares made by such Holder pursuant to any Registration Statement. Each Holder shall provide the Company with such

-17-

information about such Holder’s offer and sale of Registrable Common Shares pursuant to any Registration Statement as the Company shall reasonably request to enable the Company and its Affiliates to comply with Regulation M under the Exchange Act in connection with any such offer and sale.

10. Registration Expenses. The Company shall pay all Registration Expenses in connection with all registrations pursuant to this Agreement to the extent provided herein. In connection with all such registrations, each Holder shall pay all underwriting discounts and fees, brokerage and sales commissions, and transfer and documentary stamp taxes, if any, relating to the sale or disposition of such Holder’s Registrable Common Shares pursuant to the Registration Statement, and, except as provided in clause (g) of the definition of Registration Expenses, all fees and expenses of counsel to such Holder.

11. Indemnification; Contribution.

(a) The Company shall indemnify and hold harmless, to the fullest extent permitted by law, each Holder in any offering or sale of Registrable Common Shares, each Person, if any, who participates as an underwriter in any offering and sale of Registrable Common Shares, and each Person, if any, who controls such Holder or such underwriter within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act and their respective directors, trustees, officers, partners, agents, employees and affiliates against all losses, claims, damages, liabilities and expenses (including reasonable attorneys’ fees, disbursements and expenses, as incurred, and any amounts paid in any settlement effected with the Company’s consent, which consent shall not be unreasonably withheld or delayed) (collectively, “Losses”) incurred by such party pursuant to any actual or threatened action, suit, proceeding or investigation arising out of or based upon: (i) any untrue or alleged untrue statement of a material fact contained in, or any omission or alleged omission of a material fact required to be stated in, the Registration Statement, Prospectus or preliminary Prospectus or any amendment or supplement to any of the foregoing or necessary to make the statements therein (in the case of a Prospectus or a preliminary Prospectus, in the light of the circumstances then existing) not misleading, except in each case insofar as such statements or omissions arise out of or are based upon (A) any such untrue statement or alleged untrue statement or omission or alleged omission made in reliance on and in conformity with information with respect to such Holder furnished in writing to the Company by such Holder or its counsel expressly for use therein, (B) the use of any Prospectus after such time as the obligation of the Company to keep effective the Registration Statement of which such Prospectus forms a part has expired or (C) the use of any Prospectus after such time as the Company has advised the Holders that the filing of an amendment or supplement thereto is required, except such Prospectus as so amended or supplemented; or (ii) any violation by the Company of any other federal or state securities laws or regulations applicable to the Company and relating to action required of or inaction by the Company in connection with any such registration. Notwithstanding the foregoing provisions of this Section 8(a), the Company shall not be liable to any such Holder or underwriter or to any other indemnified party under the indemnity agreement in this Section 8(a) for any Losses that arise out of or are based upon an untrue statement or alleged untrue statement or omission or alleged omission made in any Prospectus if either: (i) (A) such Holder or underwriter failed to send or deliver a copy of the Prospectus with or prior to the delivery of written confirmation of the

-18-

sale of Registrable Common Shares by such Holder or underwriter to the Person asserting the claim from which such Losses arise and (B) the Prospectus would have corrected such untrue statement or alleged untrue statement or such omission or alleged omission; or (ii) (A) such untrue statement or alleged untrue statement or omission or alleged omission is corrected in an amendment or supplement to the Prospectus and (B) having previously been furnished by or on behalf of the Company with copies of the Prospectus as so amended or supplemented as required hereunder, such Holder or underwriter thereafter fails to deliver such Prospectus, as so amended or supplemented, with or prior to the delivery of written confirmation of the sale of Registrable Common Shares by such Holder or underwriter to the Person asserting the claim from which such Losses arise. Such rights to indemnity and reimbursement of expenses shall survive the transfer of the Registrable Common Shares by such indemnified party.

(b) In connection with any Registration Statement filed pursuant to this Agreement, each Holder of Registrable Common Shares to be covered thereby shall, severally and not jointly with any other Holders, indemnify and hold harmless, to the fullest extent permitted by law, the Company, each Person, if any, who participates as an underwriter in any offering and sale of Registrable Common Shares and each Person, if any, who controls the Company or such underwriter within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, and their respective directors, trustees, officers, partners, agents, employees and affiliates, against all Losses incurred by such party pursuant to any actual action, suit, proceeding or investigation arising out of or based upon any untrue or alleged untrue statement of a material fact contained in, or any omission or alleged omission of a material fact required to be stated in, the Registration Statement, Prospectus or preliminary Prospectus or any amendment or supplement to any of the foregoing or necessary to make the statements therein (in case of a Prospectus or preliminary Prospectus, in the light of the circumstances then existing) not misleading, but only to the extent that any such untrue statement or omission is made in reliance on and in conformity with information with respect to such Holder furnished in writing to the Company by such Holder or its counsel specifically for use therein; provided, however, that no Holder shall be required to indemnify the Company or any other indemnified party under this Section 11(b) with respect to any amount in excess of the amount of the total net proceeds received by such Holder from sales of the Registrable Common Shares of such Holder under such Registration Statement.

(c) Any Person entitled to indemnification hereunder agrees to give prompt written notice to the indemnifying party after the receipt by such indemnified party of any written notice of the commencement of any action, suit, proceeding or investigation or threat thereof made in writing for which such indemnified party may claim indemnification or contribution pursuant to this Agreement, provided that failure to give such notification shall not affect the obligations of the indemnifying party pursuant to this Section 11 except to the extent the indemnifying party shall have been actually and materially prejudiced as a result of such failure. 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 therein and, to the extent that it shall wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel reasonably satisfactory to such indemnified party, and after notice from the indemnifying

-19-

party to such indemnified party of its election so to assume the defense thereof, the indemnifying party shall not be liable to such indemnified party for any legal expenses of other counsel or any other expenses, in each case subsequently incurred by such indemnified party, in connection with the defense thereof other than reasonable costs of investigation, unless in the reasonable judgment of any indemnified party, based on the opinion of counsel, a conflict of interest is likely to exist between the indemnifying party and such indemnified party and any other of such indemnified parties with respect to such claim, in which event the indemnifying party shall not be liable for the fees and expenses of (i) more than one counsel for all Holders of Registrable Common Shares who are indemnified parties, selected by the Holders of a Majority of the Registrable Common Shares who are indemnified parties (which selection shall be reasonably satisfactory to the Company), (ii) more than one counsel for the underwriters in an Underwritten Offering or (iii) more than one counsel for the Company, in each case in connection with any one action or separate but similar or related actions. An indemnifying party who is not entitled to, or elects not to, assume the defense of a claim shall not be obligated to pay the fees and expenses of more than one counsel for all parties indemnified by such indemnifying party with respect to such claim, unless in the reasonable judgment of any indemnified party, based on the opinion of counsel, a conflict of interest is likely to exist between an indemnified party and any other of such indemnified parties with respect to such claim, in which event the indemnifying party shall be obligated to pay the fees and expenses of such additional counsel, provided that the indemnifying party shall not be liable for the fees and expenses of (i) more than one counsel for all Holders of Registrable Common Shares who are indemnified parties, selected by the Holders of a Majority of the Registrable Common Shares who are indemnified parties (which selection shall be reasonably satisfactory to the Company), (ii) more than one counsel for the underwriters in an Underwritten Offering or (iii) more than one counsel for the Company, in each case in connection with any one action or separate but similar or related actions. No indemnifying party, in defense of any such action, suit, proceeding or investigation, shall, except with the consent of each indemnified party, consent to the entry of any judgment or entry into any settlement which does not include as an unconditional term thereof the giving by the claimant or plaintiff to such indemnified party of a release from all liability in respect to such action, suit, proceeding or investigation to the extent such liability is covered by the indemnity obligations set forth in this Section 11. No indemnified party shall consent to entry of any judgment or entry into any settlement without the consent of each indemnifying party.

(d) If the indemnification from the indemnifying party provided for in this Section 11 is unavailable to an indemnified party hereunder in respect to any Losses, 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 in such proportion as is appropriate to reflect the relative fault of the indemnifying party and indemnified party in connection with the actions which resulted in such Losses, as well as any other relevant equitable considerations; provided, however, that no Holder shall be required to contribute any amount in excess of the amount of the total net proceeds received by such Holder from sales of the Registrable Common Shares of the Holder under the applicable Registration Statement. The relative fault of such indemnifying party and indemnified party shall be determined by reference to, among other things, whether any action in question, including any untrue statement 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

-20-

information supplied by, such indemnifying party or indemnified party, 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 as a result of the Losses referred to above shall be deemed to include, subject to the limitations set forth in Section 11(c), any legal or other fees and expenses reasonably incurred by such indemnified party in connection with any investigation or proceeding. 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 parties agree that it would not be just and equitable if contribution pursuant to this Section 11(d) were determined by pro rata allocation or by any other method of allocation that does not take into account the consideration referred to in this Section 11(d). If indemnification is available under this Section 11, the indemnifying parties shall indemnify each indemnified party to the full extent provided in Section 11(a) or 11(b), as the case may be, without regard to the relative fault of such indemnifying parties or indemnified party or any other equitable consideration provided for in this Section 11(d).

(e) The provisions of this Section 11 shall be in addition to any liability which any indemnifying party may have to any indemnified party and shall survive the termination of this Agreement.

(f) The indemnification and contribution required by this Section 11 shall be made by periodic payments of the amount thereof during the course of any action, suit, proceeding or investigation, as and when invoices are received or Losses are incurred.

12. Participation in Underwritten Offerings. No Holder of Registrable Common Shares may participate in any Underwritten Offering pursuant to this Agreement unless such Holder (i) agrees to sell such Holder’s Registrable Common Shares on the basis provided in any underwriting arrangements approved by the Company, which approval shall not be unreasonably withheld or delayed, and (ii) completes and executes all questionnaires, powers of attorney, custody agreements, indemnities, underwriting agreements and other documents reasonably required under the terms of such underwriting arrangements.

13. Reports Under the Exchange Act. For so long as any Registrable Common Shares remain outstanding, the Company shall use best efforts to file with the SEC in a timely manner all reports required to be filed by the Company pursuant to Section 13 or 15(d) of the Exchange Act and shall furnish to any Holder, upon request by such Holder, a written statement by the Company as to whether it has complied with the current public information requirements of Rule 144(c) under the Securities Act.

14. No Inconsistent Agreements; Most Favorable Provisions. The Company is not currently a party to, and after the date hereof shall not enter into, any agreement which is inconsistent with the rights granted to the Holders of Registrable Common Shares by this Agreement. The Holders agree for purposes of this Section 14 that none of the Series A Registration Rights Agreement, as amended, or the WCAS Registration Rights Agreement, as amended, in each case, as in effect on the date hereof, is inconsistent with the rights of the Holders hereunder. If the Company shall further amend the Series A Registration Rights Agreement or the WCAS Registration Rights Agreement or enter into any agreement after

-21-

the date hereof with any other Person pursuant to which the Series A Preferred Stockholders under the Series A Registration Rights Agreement, the WCAS Securityholders under the WCAS Registration Rights Agreement or such other Person under such other agreement, as the case may be, shall have registration rights with respect to any security of the Company that are materially more favorable to the Series A Preferred Stockholders, the WCAS Securityholders or such other Person, as the case may be, than those set forth in this Agreement, this Agreement shall thereupon, and without any further action on the part of any Holder or the Company, be deemed to be, and shall be, automatically amended to provide such materially more favorable rights to the Holders. Notwithstanding the foregoing provisions of this Section 14, this Section 14 shall not apply to, and shall not provide the Holders with any rights with respect to, any agreement relating to a Rule 144A Resale Shelf Registration.

15. Assignment of Registration Rights. The right to cause the Company to register Registrable Common Shares pursuant to this Agreement may be assigned (but only with all related obligations hereunder) by any Holder in connection with a transfer of such Registrable Common Shares to any transferee who, immediately following such transfer, holds at least 5% of then-outstanding Registrable Common Shares (calculated on an as-converted basis, assuming that all outstanding Registrable Common Shares that are convertible into or exercisable for Common Stock are converted into or exercised for Common Stock); provided that, as a condition to the effectiveness of such assignment, such transferee shall be required to execute a counterpart of this Agreement. Upon such transferee’s execution of such counterpart, such transferee shall be deemed to be a Holder for all purposes of this Agreement and shall be entitled to the benefits of, and shall be subject to the restrictions contained in, this Agreement, as amended from time to time, as a Holder hereunder to the same extent as if such transferee had originally been included in the definition of a Holder and had originally been a party hereto. Notwithstanding the foregoing, a Permitted Transferee (as defined in the Amended and Restated Governance Agreement) who otherwise would become entitled to registration rights in accordance with the foregoing provisions of this Section 15 in connection with a Distribution In Kind (as defined in the Amended and Restated Governance Agreement) of Registrable Common Shares shall not become entitled to any such registration rights under this Agreement unless such Permitted Transferee becomes bound by the Amended and Restated Governance Agreement.

16. Binding Effect; Benefit. This Agreement shall inure to the benefit of and be binding upon the parties hereto, any Holder and any successor, permitted assign, heir and legal representative thereof; provided, however, that, except as provided in Section 15, this Agreement and the provisions of this Agreement that are for the benefit of the Holders shall not be assignable by any Holder, and any such purported assignment shall be null and void. Except to the extent provided in Section 11, nothing in this Agreement, expressed or implied, is intended to confer upon any Person other than the Company, the Holders and their respective successors, permitted assigns, heirs and legal representatives any rights, remedies, obligations or liabilities under or by reason of this Agreement. No purchaser of Registrable Common Shares from a Holder shall be deemed to be a successor or assignee of such Holder merely by reason of such purchase.

-22-

17. Amendments and Waivers. The provisions of this Agreement, including the provisions of this sentence, may not be amended, modified or supplemented, and waivers or consents to departures from the provisions hereof (each such amendment, modification, supplement, waiver or consent, an “Amendment”) may not be given, unless the Company has obtained the written consent thereto of Holders of a Majority of the Registrable Common Shares; provided that if any Amendment would materially and adversely affect any Holder disproportionately relative to any other Holder or Holders, then such Amendment shall also require the written consent of Holders holding a Majority of the Registrable Common Shares held by all Holders so disproportionately affected. Notwithstanding the foregoing, an Amendment with respect to a matter that relates exclusively to the rights of Holders of Registrable Common Shares whose securities are being included in a Registration Statement and that does not directly or indirectly affect the rights of other Holders of Registrable Common Shares shall be effective if consented to by Holders of at least a Majority of the Registrable Common Shares being included in such Registration Statement; provided that the provisions of this sentence may not be amended, modified or supplemented, nor may waivers or departures from the provisions thereof be given, except in accordance with the provisions of the immediately preceding sentence. Each Holder of Registrable Common Shares outstanding at the time of any such Amendment thereafter shall be bound by any such Amendment effected pursuant to this Section 17, whether or not any notice, writing or marking indicating such Amendment appears on the Registrable Common Shares or is delivered to such Holder.

18. Notices. All notices, demands, requests, consents or other communications to be given or delivered under or by reason of the provisions of this Agreement shall be in writing and shall be deemed to have been given when (i) delivered personally to the recipient, (ii) sent by confirmed facsimile or confirmed electronic mail transmission before 5:00 p.m. New York City time on a Business Day, and otherwise on the next Business Day, or (iii) one Business Day after being sent to the recipient by reputable overnight courier service (charges prepaid). Such notices, demands, requests, consents and other communications shall be sent (i) if to the Company, to ITC^DeltaCom, Inc., 0000 X.X. Xxxxxxx Xxxxx, Xxxx Xxxxx, Xxxxxxx 00000, Attention: General Counsel, telecopy no.: (000) 000-0000, or to such other address as the Company shall designate in writing to the Holders from time to time, and (ii) if to any Holder, to such Holder at the address of such Holder set forth on the signature pages hereto, or to such other address of any Holder as such Holder shall designate in writing to the Company from time to time.

19. Headings. The headings contained in this Agreement are for convenience only and shall not affect the meaning or interpretation of this Agreement.

20. Counterparts; Effectiveness. This Agreement may be executed in any number of counterparts, each of which shall be deemed to be an original and all of which together shall be deemed to be one and the same instrument. This Agreement shall become effective as between the Company and any Holder when the Company and such Holder shall have received a copy of counterparts hereof signed by the other.

21. Governing Law. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF
