Section 2. Initial Shelf Registration; Liquidated Damages.

(a) Initial Shelf Registration.

(i) Subject to the terms and conditions of this Agreement, the Company agrees to use its best efforts to prepare and file with the SEC, as soon as reasonably practicable, but in no event later than June 15, 2011 (the “Filing Deadline”), a registration statement (together with the prospectus, amendments and supplements to such registration statement or prospectus, including pre- and post-effective amendments, all exhibits thereto, and all material incorporated by reference or deemed to be incorporated by reference in such registration statement, the “Initial Shelf Registration”) covering the resale of all of the Registrable Securities that are owned by the USH Investor or its Affiliates for an offering to be made on a continuous basis; provided, however, that the USH Investor shall not be named as an “underwriter” in the Initial Shelf Registration without the USH Investor’s prior written consent. Subject to the terms of this Agreement, the Company shall use its best efforts to cause such Initial Shelf Registration to be declared effective under the Securities Act as promptly as possible after the filing thereof, but in any event prior to July 31, 2011, and shall use its best efforts to keep such Initial Shelf Registration continuously effective under the Securities Act during the period (the “Effectiveness Period”) ending on the earlier of (i) the date on which all Registrable Securities included in such registration have been sold or distributed pursuant to the Initial Shelf Registration, or (ii) the date as of which no Registrable Securities are outstanding. The Initial Shelf Registration Statement may be used by the USH Investor and/or Affiliates from time to time to complete one or more underwritten offerings as contemplated by this Agreement.

(ii) If at any time the SEC takes the position that the offering of some or all of the Registrable Securities in a Initial Shelf Registration is not eligible to be made on a delayed or continuous basis under the provisions of Rule 415 under the Securities Act or requires the USH Investor to be named as an “underwriter”, the Company shall use its best efforts to persuade the SEC that the offering contemplated by the Initial Shelf Registration is a valid secondary offering and not an offering “by or on behalf of the issuer” as defined in Rule 415 and that the USH Investor is not an “underwriter”. The USH Investor shall have the right to participate or have their counsel participate in any meetings or discussions with the SEC regarding the SEC’s position and to comment or have their counsel comment on any written submission made to the SEC with respect thereto. No such written submission shall be made to the SEC to which the USH

-5-

Investor’s counsel reasonably objects. In the event that, despite the Company’s best efforts and compliance with the terms of this Section 2(a)(ii), the SEC refuses to alter its position, the Company shall (i) remove from the Initial Shelf Registration such portion of the Registrable Securities (the “Cut Back Shares”) and/or (ii) agree to such restrictions and limitations on the registration and resale of the Registrable Securities as the SEC may require to assure the Company’s compliance with the requirements of Rule 415 (collectively, the “SEC Restrictions”); provided, however, that the Company shall not agree to name the USH Investor as an “underwriter” in such Initial Shelf Registration without the prior written consent of the USH Investor. The Company shall use it best efforts to allocate any cut-back imposed on the USH Investor pursuant to this Section 2(a)(ii) among the USH Investor and the PIPE Investors on a pro rata basis. No liquidated damages under Section 2(b) shall accrue as to any Cut Back Shares until such date as the Company is able to effect the registration of such Cut Back Shares in accordance with any SEC Restrictions (such date, the “Restriction Termination Date” of such Cut Back Shares). From and after the Restriction Termination Date applicable to any Cut Back Shares, all of the provisions of this Section 2(a) (including the liquidated damages provisions) shall again be applicable to such Cut Back Shares; provided, however, that (i) the filing deadline for the Initial Shelf Registration including such Cut Back Shares shall be the later of June 15, 2011 and ten (10) Business Days after such Restriction Termination Date, and (ii) the date by which the Company is required to obtain effectiveness with respect to such Cut Back Shares under Section 2(b) shall be the later of July 15, 2011 (or within 16 days thereafter, to the extent such extension is required a result of the SEC processing responses to SEC comments made regarding the filed Registration Statement) and the 90th day immediately after the Restriction Termination Date.

(b) Liquidated Damages. If: (i) the Initial Shelf Registration is not filed on or prior to Filing Deadline, (ii) the Company fails to have the Initial Shelf Registration declared effective under the Securities Act prior to July 31, 2011 (the “Registration Deadline”), or (iii) after a Initial Shelf Registration is declared effective, such Initial Shelf Registration ceases for any reason to remain continuously effective as to all Registrable Securities included in such Initial Shelf Registration, or the holders of such Registrable Securities are otherwise not permitted to utilize the prospectus therein to resell such Registrable Securities (other than during an Allowable Grace Period (as defined below)), or (iv) a Grace Period (as defined below) exceeds the Allowable Grace Period (any such failure or breach being referred to as an “Event,” and for purposes of clause (i) and (ii), the date on which such Event occurs, or for purposes of clause (iii) the date on which such Initial Shelf Registration ceases to be effective, or the holders of such Registrable Securities are otherwise not permitted to utilize the prospectus therein to resell such Registrable Securities (other than during an Allowable Grace Period), or for purposes of clause (iv) the date on which the Allowable Grace Period is exceeded, being referred to as “Event Date”), then, in addition to any other rights the holders of such Registrable Securities may have hereunder or under applicable law, on each such Event Date and on each monthly anniversary of each such Event Date (for the avoidance of doubt, if an Event is cured prior to a monthly anniversary of an Event Date, the Company shall be responsible for paying to the holders of Registrable Securities their pro rata portion of the liquidated damages for that portion of the monthly anniversary period during which such Event is not cured) until the applicable Event is cured, the Company shall pay to each holder of Registrable Securities their pro rata

-6-

portion of $900,000 in cash, for any month when the Event remains uncured, as partial liquidated damages and not as a penalty. Notwithstanding the foregoing, (A) no liquidated damages shall accrue after the date as of which all of the Registrable Securities included in such registration are able to be sold by the USH Investor and its Affiliates and all other holders of Registrable Securities pursuant to Rule 144(b)(1) without compliance with the current public information requirements of such rule, and (B) no liquidated damages shall accrue during any period during which the Company has advised the holders of Registrable Securities to suspend the use of any prospectus, provided such period does not exceed the Allowable Grace Period. If the Company fails to pay any partial liquidated damages pursuant to this Section in full within seven calendar days after the date payable, the Company will pay interest thereon at a rate of 12% per annum (or such lesser maximum amount that is permitted to be paid by applicable law) to the holders, accruing daily from the date such partial liquidated damages are due until such amounts, plus all such interest thereon, are paid in full. The partial liquidated damages pursuant to the terms hereof shall apply on a daily pro rata basis for any portion of a month prior to the cure of an Event. Notwithstanding the foregoing, an “Event” shall not include a Initial Shelf Registration not remaining effective if the Company has advised the holders of Registrable Securities to suspend the use of any prospectus pursuant to Section 2(c), provided such period does not exceed the Allowable Grace Period. In addition, an “Event” with respect to the USH Investor shall not include an Event that occurs as a result of a Initial Shelf Registration not being filed, not being declared effective, or not remaining effective as a result of the USH Investor failing to timely provide the Company with information requested by the Company and necessary to complete the Initial Shelf Registration in accordance with the requirements of the Securities Act, and then the liquidated damages shall not be accrued or payable to the USH Investor who has not provided such information.

(c) Grace Periods. Notwithstanding anything to the contrary herein, at any time after any Registration Statement (as defined below) has been declared effective by the SEC, the Company may delay the disclosure of material non-public information concerning the Company if the disclosure of such information at the time is not, in the good faith judgment of the Company, in the best interests of the Company (a “Grace Period”); provided, however, the Company shall promptly (i) notify the holders of Registrable Securities in writing (including via facsimile or other electronic transmission) of the existence of material non-public information giving rise to a Grace Period (provided that the Company shall not disclose the content of such material non-public information to the holders) or the need to file a supplement or post-effective amendment, as applicable, and the date on which such Grace Period will begin, and (ii) notify the holders of Registrable Securities in writing (including via facsimile or other electronic transmission) of the date on which the Grace Period ends; provided, further, that no single Grace Period shall exceed thirty (30) consecutive days, and during any three hundred sixty-five (365) day period, the aggregate of all Grace Periods shall not exceed an aggregate of sixty (60) days (each Grace Period complying with this provision being an “Allowable Grace Period”). For purposes of determining the length of a Grace Period, the Grace Period shall be deemed to begin on and include the date the holders receive the notice referred to in clause (i) above and shall end on and include the later of the date the holders receive the notice referred to in clause (ii) above and the date referred to in such notice; provided, however, that no Grace Period shall be longer than an Allowable Grace Period.

-7-

(d) Public Disclosure. The Company shall, and shall provide the USH Investor with a written confirmation of the same, upon (x) the earliest to occur of (i) the announcement of the closing of the proposed $200 million senior secured note offering announced by the Company on a press release dated March 1, 2011 (the “Note Offering”), which announcement must be made no later than one Business Day after the closing of the Note Offering, (ii) the termination or abandonment of the Note Offering, (iii) the refinancing of the Credit and Guaranty Agreement, dated November 17, 2010, as amended by that certain Amended and Restated Amendment No. 1 to Credit Agreement dated as of January 6, 2011 and as amended by that certain Amendment No. 2 to Credit Agreement dated as of March 2, 2011, by and among the Company, certain of the Company’s subsidiaries, U.S. Healthcare I and U.S. Healthcare II and (iv) March 31, 2011 (the “First Disclosure Date”), (y) the earlier of (i) the Registration Deadline or (ii) the time the Initial Registration Statement is declared effective by the SEC as contemplated by Section 2(a)(i) of this Agreement (the “Second Disclosure Date”) and (z) any time following the First Disclosure Date and for so long as the USH Investor or any of its Affiliates continues to own any Warrants, within three Business Days of being requested by the USH Investor (a “Subsequent Disclosure Date”, and each of the First Disclosure Date, the Second Disclosure Date and a Subsequent Disclosure Date, a “Disclosure Date”), publicly disclose in a Current Report on Form 8-K or such other periodic report required or permitted to be filed under the Exchange Act with the SEC all of the previously publicly undisclosed confidential information provided to the USH Investor or its Affiliates by the Company that in the Company’s reasonable judgment, after consultation with its outside counsel, constitutes material non-public information (such disclosure made on the First Disclosure Date, the “First Disclosure”, such disclosure made on the Second Disclosure Date, the “Second Disclosure” and such disclosure made on a Subsequent Disclosure Date, a “Subsequent Disclosure”, and each of the First Disclosure, the Second Disclosure and a Subsequent Disclosure, a “Disclosure”). Any such request for a Subsequent Disclosure by the USH Investor shall be in writing and shall contain a representation by the USH Investor that it has a good faith belief that such disclosure is required in order for the USH Investor to engage in any type of transaction that relates, directly or indirectly, to the Company’s Capital Stock, or other securities related thereto, when such three Business Day period expires. The Company shall provide the USH Investor with a copy of each Disclosure at least two Business Days prior to its release. If the USH Investor has not delivered a Potential Supplemental Disclosure Notice (as defined below) with respect to a Disclosure prior to its release, the USH Investor shall not have the right to make a USH Investor Disclosure (as defined below) with respect to such Disclosure. If the USH Investor believes the Company may have failed to make a Disclosure on or before the applicable Disclosure Date, fails to include in any Disclosure, or draft Disclosure provided to the USH Investor prior to its release, all of the material non-public information previously provided to the USH Investor, the USH Investor may provide the Company with a written notice setting forth the material non-public information which the Company has failed to disclose or include in such draft disclosure (a “Potential Supplemental Disclosure Notice”). The Company may, within two Business Days of receiving a Potential Supplemental Disclosure Notice, provide the USH Investor with a written certification that, based on the reasonable advice of its outside counsel, the Company has determined that all or part of the information specified in the Potential Supplemental Disclosure Notice is not material and therefore the USH Investor is not in possession of material non-public information received from the Company. The Company shall be obligated to publicly disclose all of the information in the Potential Supplemental Disclosure Notice which it has failed to so certify is

-8-

not material (the “Supplemental Material Information”). If the Company fails to publicly disclose the Supplemental Material Information on or before the later of (i) the applicable Disclosure Date and (ii) two Business Days after receiving the Potential Supplemental Disclosure Notice, then, without limitation on any other rights available to the USH Investor, the Company agrees that the USH Investor is authorized to make the Supplemental Material Information or any portion thereof available to the public generally (a “USH Investor Disclosure”). The USH Investor shall not have any liability to the Company, its subsidiaries, or any of its or their respective officers, directors, employees, stockholders or agents for any such disclosure. Notwithstanding the foregoing, solely after the First Disclosure Date, no disclosure of confidential information by the Company contemplated by this Section 2(d) shall be required (i) during a Grace Period or (ii) if the USH Investor has accepted material non-public information for review after the First Disclosure Date in accordance with clause (i) of the last paragraph of Section 9(a), if such disclosure would cause the Company to breach any material confidentiality obligation or the terms of any other material contract or agreement of the Company; provided, however, that the Company shall use commercially reasonable efforts to amend or eliminate such confidentially obligations or contract or agreement terms that prevent such disclosure.

(e) Lock Up Agreement. During the period commencing on the date of this Agreement and continuing until the time the Initial Registration Statement is declared effective by the SEC as contemplated pursuant to Section 2(a)(i) of this Agreement, the Company shall not: (i) offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, lend, or otherwise transfer or dispose of, directly or indirectly, any shares of Common Stock or any securities convertible into or exercisable or exchangeable for Common Stock, (ii) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of the Common Stock, whether any such transaction described in clause (i) or (ii) above is to be settled by delivery of Common Stock or such other securities, in cash or otherwise or (iii) permit any registration statement filed with the SEC relating to the offering of the PIPE Securities or any shares of Common Stock or any securities convertible into or exercisable or exchangeable for Common Stock held by the PIPE Investors (or any of their transferees) to be declared effective by the SEC. Notwithstanding the foregoing, clauses (i) and (ii) of the immediately preceding sentence shall not apply to any Excluded Shares (as defined in the Warrants).

(b) Long-Form Registrations. The holders of Registrable Securities shall be entitled to request up to three Long-Form Registrations in which the Company shall pay all Registration Expenses (as defined in Section 6(a)), whether or not any such registration is consummated.

(c) Short-Form Registrations. In addition to the Long-Form Registrations provided pursuant to Section 3(b), the holders of Registrable Securities shall be entitled to request an unlimited number of Short-Form Registrations in which the Company shall pay all Registration Expenses.

(d) Priority on Registration Statements.

If a Registration Statement is an underwritten offering and the managing underwriters advise the Company in writing that in their opinion the number of Registrable Securities and, if permitted hereunder, other securities requested to be included in such offering exceeds the number of Registrable Securities and other securities, if any, which can be sold therein without adversely affecting the marketability, proposed offering price, timing or method of distribution of the offering, the Company shall include in such registration prior to the inclusion of any securities which are not Registrable Securities the number of Registrable Securities requested to be included which, in the opinion of such underwriters, can be sold, without any such adverse effect, pro rata among the respective holders thereof on the basis of the amount of Registrable Securities owned by each such holder.

(e) Selection of Underwriters. The holders of a majority of the Registrable Securities included in an underwritten offering shall have the right to select the investment banker(s) and manager(s) to administer the offering and the Company shall pay all reasonable expenses in connection therewith.

-13-

(vii) notify each seller of such Registrable Securities (A) promptly after it receives notice thereof, of the date and time when such registration statement and each post-effective amendment thereto has become effective or a prospectus or supplement to any prospectus relating to a registration statement has been filed and when any registration or qualification has become effective under a state securities or blue sky law or any exemption thereunder has been obtained, (B) promptly after receipt thereof, of any request by the SEC for the amendment or supplementing of such registration statement or prospectus or for additional information, and (C) at any time when a prospectus relating thereto is required to be delivered under the Securities Act, of the happening of any event as a result of which the prospectus included in such registration statement contains an untrue statement of a material fact or omits any fact necessary to make the statements therein not misleading, and, at the request of any such seller, the Company shall prepare a supplement or amendment to such prospectus so that, as thereafter delivered to the purchasers of such Registrable Securities, such prospectus shall not contain an untrue statement of a material fact or omit to state any fact necessary to make the statements therein not misleading;

(xii) take all reasonable actions to ensure that any Issuer Free-Writing Prospectus utilized in connection with any Registration Statement hereunder complies in all material respects with the Securities Act, is filed in accordance with the Securities Act

Section 6. Registration Expenses.

(a) The Company’s Obligation. All expenses incident to the Company’s performance of or compliance with this Agreement (including, without limitation, all registration, qualification and filing fees, fees and expenses of compliance with securities or blue sky laws, printing expenses, messenger and delivery expenses, fees and disbursements of custodians, and fees and disbursements of counsel for the Company, reasonable fees and expenses billed at the standard hourly rates of one counsel to the USH Investor and the USH Investor’s reasonable expenses in connection with the registration, and all independent certified public accountants, underwriters and other Persons retained by the Company) (all such expenses being herein called “Registration Expenses”), shall be borne by the Company.

(b) Counsel Fees and Disbursements. In connection with each Registration Statement, the Company shall reimburse the holders of Registrable Securities included in such registration for the reasonable fees and disbursements of one counsel chosen by a majority of the

-16-

holders of the Registrable Securities requesting such registration for the purpose of rendering a legal opinion on behalf of such holder in connection with any underwritten Registration Statement.

Section 7. Indemnification and Contribution.

(a) By the Company. The Company shall indemnify and hold harmless, to the extent permitted by law, each holder of Registrable Securities, such holder’s officers, directors employees, agents and representatives, and each Person who controls such holder (within the meaning of the Securities Act) (the “Indemnified Parties”) against all losses, claims, actions, damages, liabilities and expenses (including with respect to actions or proceedings, whether commenced or threatened, and including attorney fees and expenses) caused by, resulting from, arising out of, based upon or related to any of the following statements, omissions or violations (each a “Violation”) by the Company: (i) any untrue or alleged untrue statement of material fact contained in (A) any registration statement pursuant to which Registrable Securities are registered, any prospectus, preliminary prospectus or Issuer Free-Writing Prospectus included in any such registration statement, or any amendment thereof or supplement thereto or (B) any application or other document or communication (in this Section 7, collectively called an “application”) executed by or on behalf of the Company or based upon written information furnished by or on behalf of the Company filed in any jurisdiction in order to qualify any Registrable Securities covered by such registration under the securities laws thereof, (ii) any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading or (iii) any violation or alleged violation by the Company of the Securities Act or any other similar federal or state securities laws or any rule or regulation promulgated thereunder applicable to the Company and relating to action or inaction required of the Company in connection with any such registration, qualification or compliance; provided that the Company will not be liable for losses arising out of written information provided by a holder for inclusion in the registration statement or sales of Registrable Securities made during a Grace Period, after notice has been given by the Company. In addition, the Company will reimburse such Indemnified Party for any reasonable legal or any other expenses incurred by them in connection with investigating or defending any such losses.

(b) By Each Security Holder. In connection with any registration statement in which a holder of Registrable Securities is participating, each such holder shall furnish to the Company in writing such information and affidavits as the Company reasonably requests for use in connection with any such registration statement or prospectus and, to the extent permitted by law, shall indemnify the Company, its officers, directors, employees, agents and representatives, and each Person who controls the Company (within the meaning of the Securities Act) against any losses, claims, damages, liabilities and expenses resulting from any untrue or alleged untrue statement of material fact contained in the registration statement, prospectus, preliminary prospectus or Issuer Free-Writing Prospectus or any amendment thereof or supplement thereto or any omission or alleged omission of 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 or omission is contained in any information or affidavit so furnished in writing by such holder specifically for inclusion in such registration statement or prospectus or amendment or supplement thereto; provided that the obligation to indemnify shall be individual, not joint and several, for each holder (with no holder being responsible for any misstatements or omissions of

-17-

any other holder) and shall be limited to the amount of proceeds (net of all expense paid by such holder in connection with any claim relating to this Section 7 and the amount of any damages such holder has otherwise been required to pay by reason of such untrue statement or omission) received by such holder from the sale of securities pursuant to such registration statement giving rise to such indemnification obligation.

(c) Claim Procedure. Any Person entitled to indemnification hereunder shall (i) give prompt written notice to the indemnifying party of any claim with respect to which it seeks indemnification (provided that the failure to give prompt notice shall impair any Person’s right to indemnification hereunder only to the extent such failure has prejudiced the indemnifying party) and (ii) unless in such indemnified party’s judgment a conflict of interest between such indemnified and indemnifying parties may exist with respect to such claim, permit such indemnifying party to assume the defense of such claim with counsel reasonably satisfactory to the indemnified party. If such defense is assumed, the indemnifying party shall not be subject to any liability for any settlement made by the indemnified party without its consent (but such consent shall not be unreasonably withheld, conditioned or delayed). 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 judgment of any indemnified party a conflict of interest may exist between such indemnified party and any other of such indemnified parties with respect to such claim. In such instance, the conflicted indemnified parties shall have a right to retain one separate counsel, chosen by the holders of the Registrable Securities included in the registration if such holders are indemnified parties, at the expense of the indemnifying party.

(d) Contribution. If the indemnification provided for in this Section 7 is held by a court of competent jurisdiction to be unavailable to, or is insufficient to hold harmless, an indemnified party or is otherwise unenforceable with respect to any loss, claim, damage, liability or action referred to herein, then the indemnifying party shall contribute to the amounts paid or payable by such indemnified party as a result of such loss, claim, damage, liability or action in such proportion as is appropriate to reflect the relative fault of the indemnifying party on the one hand and of the indemnified party on the other hand in connection with the statements or omissions which resulted in such loss, claim, damage, liability or action as well as any other relevant equitable considerations. The relative fault of the indemnifying party and of the indemnified party shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission to state a material fact relates to information supplied by the indemnifying party or by the indemnified party and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The parties hereto agree that it would not be just or equitable if the contribution pursuant to this Section 7(d) were to be determined by pro rata allocation or by any other method of allocation that does not take into account such equitable considerations. The amount paid or payable by an indemnified party as a result of the losses, claims, damages, liabilities or expenses referred to herein shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending against any action or claim which is the subject hereof. 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 is not guilty of such fraudulent misrepresentation.

-18-

Notwithstanding anything to the contrary, in no event shall the contribution obligation of a holder of Registrable Securities be greater in amount than the dollar amount of the proceeds (net of all expenses paid by such holder in connection with any claim relating to this Section 7 and the amount of any damages such holder has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission) received by it upon the sale of the Registrable Securities giving rise to such contribution obligation.

(e) Release. No indemnifying party shall, except with the consent of the indemnified party, consent to the entry of any judgment or enter into any settlement that does not include as an unconditional term thereof giving by the claimant or plaintiff to such indemnified party of a release from all liability in respect to such claim or litigation.

(f) Non-exclusive Remedy; Survival. The indemnification and contribution provided for under this Agreement shall be in addition to any other rights to indemnification or contribution that any indemnified party may have pursuant to law or contract and shall remain in full force and effect regardless of any investigation made by or on behalf of the indemnified party or any officer, director or controlling Person of such indemnified party and shall survive the transfer of Registrable Securities and the termination or expiration of this Agreement.

Section 8. Underwritten Registrations; Suspended Distributions.

(a) Participation. No Person may participate in any registration hereunder which is underwritten unless such Person (i) agrees to sell such Person’s securities on the basis provided in any underwriting arrangements approved by the Person or Persons entitled hereunder to approve such arrangements (including, without limitation, pursuant to any over-allotment or “green shoe” option requested by the underwriters; provided that no holder of Registrable Securities shall be required to sell more than the number of Registrable Securities such holder has requested to include) and (ii) completes and executes all questionnaires, powers of attorney, indemnities, underwriting agreements and other documents required under the terms of such underwriting arrangements; provided that no holder of Registrable Securities included in any underwritten registration shall be required to make any representations or warranties to the Company or the underwriters (other than representations and warranties regarding such holder and such holder’s intended method of distribution) or to undertake any indemnification obligations to the Company or the underwriters with respect thereto that are materially more burdensome than those provided in Section 7.

(b) Suspended Distributions. Each Person that is participating in any registration under this Agreement, upon receipt of any notice from the Company of the happening of any event giving rise to a Grace Period, shall immediately discontinue the disposition of its Registrable Securities pursuant to the registration statement until such Person’s receipt of the copies of a supplemented or amended prospectus as contemplated by Section 5(a)(vii). In the event the Company has given any such notice, the applicable time period set forth in Section 5(a)(ii) during which a Registration Statement is to remain effective shall be extended by the number of days during the period from and including the date of the giving of such notice pursuant to this Section 8(b) to and including the date when each seller of Registrable Securities covered by such registration statement shall have received the copies of the supplemented or amended prospectus contemplated by Section 5(a)(vii).

-19-

Section 9. Current Public Information At all times after the earlier of (i) the Registration Deadline or (ii) the time the Initial Registration Statement is declared effective by the SEC as contemplated pursuant to Section 2(a)(i) of this Agreement, the Company shall file all reports required to be filed by it under the Securities Act and the Exchange Act (including all reports that were previously required to be filed prior to such time) on or prior to the date that is required to be so filed under the applicable rules and regulations of the SEC (which date shall include any additional period provided in Rule 12b-25 under the Exchange Act for the filing to be deemed timely filed, provided that the Company makes such filing within the applicable additional period) and shall take such further action as any holder or holders of Registrable Securities may reasonably request, all to the extent required to enable such holders to sell Registrable Securities pursuant to Rule 144. Upon request, the Company shall deliver to any holder of Registrable Securities a written statement as to whether it has complied with such requirements. If at any time following the date on which the Company is required to comply with this Section 9, Company fails to file a report required by the Exchange Act on or prior to the date that is required to be so filed under the applicable rules and regulations of the SEC (a “Reporting Event”), in addition to any other rights the holders of such Registrable Securities may have hereunder or under applicable law, on each such Reporting Event and on each monthly anniversary of each such Reporting Event (for the avoidance of doubt, if a Reporting Event is cured prior to a monthly anniversary of a Reporting Event, the Company shall be responsible for paying to the holders of Registrable Securities their pro rata portion of the liquidated damages for that portion of the monthly anniversary period during which such Reporting Event is not cured) until the applicable Reporting Event is cured, the Company shall pay to each holder of Registrable Securities their pro rata portion of $900,000 in cash, as partial liquidated damages and not as a penalty. Notwithstanding the foregoing, the amount of any such partial liquidated damages payable under this Section 9 shall be reduced by the amount of any liquidated damages payable by the Company pursuant to Section 2(b) hereof. If the Company fails to pay any partial liquidated damages pursuant to this Section 9 in full within seven calendar days after the date payable, the Company will pay interest thereon at a rate of 12% per annum (or such lesser maximum amount that is permitted to be paid by applicable law) to the holders, accruing daily from the date such partial liquidated damages are due until such amounts, plus all such interest thereon, are paid in full. The partial liquidated damages pursuant to the terms hereof shall apply on a daily pro rata basis for any portion of a month prior to the cure of a Reporting Event.

(a) Due Diligence Review; Information. Subject to the following paragraph of this section, the Company shall make available, during normal business hours, for inspection and review by the USH Investor, advisors to and representatives of the USH Investor (who may or may not be affiliated with the USH Investor and who are reasonably acceptable to the Company), all financial and other records, all 1934 Act Filings and other filings with the SEC, and all other corporate documents and properties of the Company as may be reasonably necessary for the purpose of such review, and cause the Company’s officers, directors and employees, within a reasonable time period, to supply all such information reasonably requested by the USH Investor or any such representative, advisor or underwriter in connection with such Registration Statement (including, without limitation, in response to all questions and other inquiries reasonably made or submitted by any of them), prior to and from time to time after the filing and effectiveness of the Registration Statement for the sole purpose of enabling the USH Investor and such representatives, advisors and underwriters and their respective accountants and attorneys to conduct initial and ongoing due diligence with respect to the Company and the accuracy of such Registration Statement.

-20-

Anything in the foregoing notwithstanding, after the First Disclosure Date, the Company shall not disclose material nonpublic information to the USH Investor, or to advisors to or representatives of the USH Investor, unless prior to disclosure of such information the Company identifies such information as being material nonpublic information and provides the USH Investor, such advisors and representatives with the opportunity to (i) accept such material nonpublic information for review, (ii) refuse to accept such material nonpublic information for review or (iii) to direct the Company to deliver any such material, nonpublic information to a division, affiliate or advisor of the USH Investor which is segregated from the USH Investor such that its receipt of such material, nonpublic information does not restrict such USH Investor from trading in the securities of the Company and any USH Investor, division, affiliate, advisor or representative, as applicable, wishing to obtain such information enters into an appropriate confidentiality agreement with the Company with respect thereto.

Section 10. Subsidiary Public Offering. If, after an initial Public Offering of the Capital Stock of one of its Subsidiaries, the Company distributes securities of such Subsidiary to its equity holders, then the rights and obligations of the Company pursuant to this Agreement shall apply, mutatis mutandis, to securities of such Subsidiary, and the Company shall cause such Subsidiary to comply with such Subsidiary’s obligations under this Agreement.

Section 11. Lock-up. For a period of 45 days after the date of the effectiveness of the Registration Statement the Company will not offer, sell, contract to sell, pledge or otherwise dispose of, directly or indirectly any additional shares of its securities or securities convertible into or exchangeable or exercisable for any shares of its securities, excluding (i) options granted to employees, directors or consultants under the Company’s stock option plans, (ii) the conversion or exercise of convertible or exercisable securities outstanding on the date hereof, (iii) the issuance of shares in connection with debt financing or similar transactions that are primarily of a non-equity financing nature and approved by the Company’s Board of Directors, (iv) securities issued pursuant to acquisitions or strategic transactions approved by the Company’s Board of Directors, and (v) securities issued in exchange for outstanding debt.

Section 12. General Provisions.

(a) Amendments and Waivers. Except as otherwise provided herein, the provisions of this Agreement may be amended, modified or waived only with the prior written consent of the Company and a majority of the holders of the Registrable Securities. The failure or delay of any Person to enforce any of the provisions of this Agreement shall in no way be construed as a waiver of such provisions and shall not affect the right of such Person thereafter to enforce each and every provision of this Agreement in accordance with its terms. A waiver or consent to or of any breach or default by any Person in the performance by that Person of his, her or its obligations under this Agreement shall not be deemed to be a consent or waiver to or of any other breach or default in the performance by that Person of the same or any other obligations of that Person under this Agreement.

-21-

(b) Remedies. The parties to this Agreement shall be entitled to enforce their rights under this Agreement specifically (without posting a bond or other security), to recover damages caused by reason of any breach of any provision of this Agreement and to exercise all other rights existing in their favor. The parties hereto agree and acknowledge that a breach of this Agreement would cause irreparable harm and money damages would not be an adequate remedy for any such breach and that, in addition to any other rights and remedies existing hereunder, any party shall be entitled to specific performance and/or other injunctive relief from any court of law or equity of competent jurisdiction (without posting any bond or other security) in order to enforce or prevent violation of the provisions of this Agreement.

(c) Severability. Whenever possible, each provision of this Agreement shall be interpreted in such manner as to be effective and valid under applicable law, but if any provision of this Agreement is held to be prohibited, invalid, illegal or unenforceable in any respect under any applicable law or regulation in any jurisdiction, such prohibition, invalidity, illegality or unenforceability shall not affect the validity, legality or enforceability of any other provision of this Agreement in such jurisdiction or in any other jurisdiction, but this Agreement shall be reformed, construed and enforced in such jurisdiction as if such prohibited, invalid, illegal or unenforceable provision had never been contained herein.

(d) Entire Agreement. Except as otherwise provided herein, this Agreement contains the complete agreement and understanding among the parties hereto with respect to the subject matter hereof and supersedes and preempts any prior understandings, agreements or representations by or among the parties hereto, written or oral, which may have related to the subject matter hereof in any way, except as may be contained in the Purchase Agreements or the Warrants.

(e) Successors and Assigns. Except as otherwise provided herein, this Agreement shall bind and inure to the benefit and be enforceable by the Company and its successors and assigns and the holders of Registrable Securities and their respective successors and permitted assigns (whether so expressed or not). In addition, whether or not any express assignment has been made, the provisions of this Agreement which are for the benefit of purchasers or holders of Registrable Securities are also for the benefit of, and enforceable by, any subsequent holder of Registrable Securities.

(f) Notices. All notices, demands or other communications to be given or delivered under or by reason of the provisions of this Agreement will be in writing and will be delivered personally, mailed by certified or registered mail, return receipt requested and postage prepaid, or sent by reputable overnight courier service (charges prepaid), to the recipient.
