Since the date of the latest balance sheet presented in the Registration Statement and the Pricing Disclosure Package, neither the Company nor any Subsidiary has incurred or undertaken any liabilities or obligations, whether direct or indirect, liquidated or contingent, matured or unmatured, or entered into any transactions, including any acquisition or disposition of any business or asset, which are material to the Company and the Subsidiaries, taken as a whole, except for liabilities, obligations and transactions which are disclosed in the Registration Statement and the Pricing Disclosure Package.

(h) The authorized, issued and outstanding capital stock of the Company is as set forth in the Registration Statement and the Pricing Disclosure Package as of the dates specified therein under the column headed “Actual” under the caption “Capitalization” and, after giving effect to the Offering, the filing of the Restated Certificate of Incorporation (as defined in Section 1(mm)) and the other transactions contemplated by this Agreement, would have been as of such date as set forth in the Prospectus in the column headed “Pro Forma As Adjusted” under the caption “Capitalization.” All of the issued and outstanding shares of capital stock of the Company are fully paid and non-assessable and have been duly and validly authorized and issued, in compliance with all applicable state, federal and foreign securities laws and not in violation of or subject to any preemptive or similar right contained in the Company’s certificate of incorporation or bylaws, each as amended as of the date of issuance of such shares, or any other agreement to which the Company was a party or under the Delaware General Corporation Law that entitled any person to acquire from the Company upon the issuance or sale of such share (i) any Common Stock or other security of the Company or (ii) any security

equity, or properties of the Company and the Subsidiaries, taken as a whole; (ii) the long-term debt or capital stock of the Company or Quatrotec; or (iii) the ability of the Company to consummate the Offering or any other transaction contemplated by this Agreement, the Registration Statement or the Pricing Disclosure Package (any such effect, a “Material Adverse Effect”).

(k) Each of the Company and Quatrotec has all requisite power and authority, and all necessary consents, approvals, authorizations, orders, registrations, qualifications, licenses, filings, certifications and permits of, with and from all judicial, regulatory and other legal or governmental agencies and bodies and all third parties, foreign and domestic (individually, a “Consent” and collectively, the “Consents”), to own, lease and operate its properties and conduct its business as it is now being conducted and as disclosed in the Registration Statement and the Pricing Disclosure Package, and each such Consent is valid and in full force and effect, except in each case as could not, individually or in the aggregate, reasonably be expected to result in a Material Adverse Effect. Neither the Company nor any Subsidiary has received notice of any investigation or proceeding which, if decided adversely to the Company or any Subsidiary, could reasonably be expected to result in a Material Adverse Effect. Each of the Company and the Subsidiaries is in compliance with all applicable laws, rules, regulations, ordinances, directives, judgments, decrees and orders, foreign and domestic, except where failure to be in compliance could not reasonably be expected to have a Material Adverse Effect.

(n) No Consent of, with or from any judicial, regulatory or other legal or governmental agency or body or any third party, foreign or domestic, is required to be obtained by the Company for the execution, delivery and performance of this Agreement or consummation of the transactions contemplated by this Agreement, including the issuance, sale and delivery of the Shares to be issued, sold and delivered hereunder, except the registration under the Securities Act of the Shares, which, based on the advice of the Commission, has become effective, the registration under the Securities Exchange Act of 1934, as amended, of the class of Common Stock of the Company, and such Consents as may be required under state or foreign securities or blue sky laws or the by-laws and rules of the National Association of Securities Dealers, Inc.

(q) The statistical, industry-related and market-related data included in the Registration Statement and the Pricing Disclosure Package are based on or derived from sources which the Company reasonably and in good faith believes are reliable, and such data agree with the sources from which they are derived.

(r) The class of Common Stock is registered pursuant to Section 12(g) of the Exchange Act and has been approved for quotation on the Nasdaq National Market System (“NASDAQ”). The Company has taken no action designed to de-list or terminate the registration of, or likely to have the effect of, terminating the registration of the Common Stock

under the Exchange Act or de-listing or terminating the quotation of the Common Stock from NASDAQ, nor has the Company received any notification that the Commission or NASDAQ is contemplating terminating such registration or de-listing.

The Company is not aware of any “material weaknesses” (as such term is defined in the PCAOB Bylaws and Rules; Auditing Standard No. 2—An Audit of Internal Control Over Financial Reporting Performed in Conjunction with an Audit of Financial Statements) in its internal control over financial reporting.

(t) No relationship, direct or indirect, exists between or among any of the Company or any affiliate of the Company, on the one hand, and any director, officer, stockholder, customer or supplier of the Company or any affiliate of the Company, on the other hand, which is required by Item 404 of Regulation S-K under the Securities Act to be described in the Registration Statement or the Pricing Disclosure Package, which is not so described and described as required.

(z) Each of the Company and Quatrotec owns or leases all such properties that are necessary to the conduct of its business, as described in the Registration Statement and the Pricing Disclosure Package, except as could not reasonably be expected to have a Material Adverse Effect. Each of the Company and Quatrotec has good and valid title in fee simple to all real property and good and valid title to all personal property owned by it, in each case free and clear of any and all Liens except such as are described in the Registration Statement and the Pricing Disclosure Package or such as do not (individually or in the aggregate) materially detract from the value of such property or materially interfere with the use made of such property by the Company and Quatrotec; and any real property and buildings held under lease or sublease by the Company and Quatrotec are held by them under valid, subsisting and enforceable leases (except as such enforceability may be subject to the laws of general application relating to bankruptcy and the relief of debtors and laws governing specific performance, injunctive relief or other equitable remedies), with such exceptions as are not material to, and do not materially interfere with, the use made of such property and buildings by the Company and Quatrotec. Neither the Company nor any Subsidiary has received any notice of any claim adverse to its ownership of any real or personal property or of any claim against the continued possession of any real property, whether owned or held under lease or sublease by the Company or any Subsidiary, except as could not reasonably be expected to have a Material Adverse Effect.

(aa) Except as otherwise described in the Registration Statement and Pricing Prospectus: (i) the Company owns or otherwise possesses rights to use all trademarks, service marks, domain names, trade names, trademark registrations, service ▇▇▇▇ registrations, copyrights, proprietary know-how, trade secrets, proprietary or confidential information and

other intellectual property, including all intellectual property rights (collectively, “Intellectual Property Rights”) material to the conduct of its business as currently being conducted or proposed to be conducted, in each case as described in the Registration Statement and the Pricing Prospectus, (ii) to the Company’s knowledge, the Company owns or otherwise possesses rights to use all patents and patent applications material to the conduct of its business as currently being conducted or proposed to be conducted, in each case as described in the Registration Statement and the Pricing Prospectus, (iii) to the Company’s knowledge, the conduct of its business as currently being conducted or proposed to be conducted, in each case as described in the Registration Statement and the Pricing Prospectus does not or will not conflict with, and the Company has not received any notice of any claim of conflict with, any such Intellectual Property Right of others that is material to the Company or the conduct of its business, (iv) to the Company’s knowledge, there is no infringement by third parties of any Intellectual Property Right owned by the Company that is material to the Company or the conduct of its business, (v) there is no pending or, to the Company’s knowledge, threatened action, suit, proceeding or claim by others challenging the Company’s rights in or to any Intellectual Property Rights owned by the Company that is material to the Company or the conduct of its business, (vi) there is no pending or, to the Company’s knowledge, threatened action, suit, proceeding or claim by others that the Company or any product or service of the Company infringes or otherwise violates any patent, trademark, copyright, trade secret or other proprietary rights of others that is material to the Company or the conduct of its business, and (vii) each of the Company and the Subsidiaries has taken reasonable steps to maintain the confidentiality of all information that the Company or any of the Subsidiaries considers to be its trade secrets.

(bb) Each of the Company and Quatrotec maintains or is covered by insurance in such amounts and covering such risks as the Company reasonably considers adequate for the conduct of its business and the value of its properties and as is customary for companies engaged in similar businesses in similar industries, all of which insurance is in full force and effect, except where the failure to maintain such insurance could not reasonably be expected to have a Material Adverse Effect. To the Company’s knowledge, there are no material claims by the Company or Quatrotec under any such policy or instrument as to which any insurance company is denying liability or defending under a reservation of rights clause. To the Company’s knowledge, it will be able to renew its existing insurance, and the insurance covering the Subsidiaries, as and when such coverage expires, or will be able to obtain replacement insurance adequate for the conduct of their businesses and the value of their properties at a cost that could not reasonably be expected to have a Material Adverse Effect.

(cc) Each of the Company and the Subsidiaries has accurately prepared and timely filed all federal, state, foreign and other tax returns that are required to be filed by it and has paid or made provision for the payment of all taxes, assessments, governmental or other similar charges, including without limitation, all sales and use taxes and all taxes which the Company or any Subsidiary is obligated to withhold from amounts owing to employees, creditors and other third parties, with respect to the periods covered by such tax returns (whether or not such amounts are shown as due on any tax return), except where the failure to file or pay could not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect. No deficiency assessment with respect to a proposed adjustment of the Company’s or any Subsidiary’s federal, state, local or foreign taxes is pending or, to the Company’s knowledge, threatened, except for deficiencies that could not, individually or in the aggregate, reasonably be

expected to have a Material Adverse Effect. To the Company’s knowledge, the accruals and reserves on the books and records of the Company and the Subsidiaries in respect of tax liabilities for any taxable period not finally determined are adequate to meet any assessments and related liabilities for any such period and, since September 30, 2005, neither the Company nor any Subsidiary has incurred any liability for taxes other than in the ordinary course of its business. There is no tax lien, whether imposed by any federal, state, foreign or other taxing authority, outstanding against the assets, properties or business of the Company or any Subsidiary, except with respect to current taxes not yet due or delinquent.

Payment of the purchase price for the Firm Shares shall be made by wire transfer in same day funds to the Company upon delivery of certificates for the Firm Shares to the Lead Manager through the facilities of The Depository Trust Company for the respective accounts of the several Underwriters against receipt therefor signed by the Lead Manager. Certificates for the Firm Shares shall be registered in such name or names and shall be in such denominations as the Lead Manager may request at least two business days prior to the Closing Date.

This option may be exercised at any time and from time to time, in whole or in part on one or more occasions, on or before the thirtieth day following the date of the Prospectus, by written notice from the Lead Manager to the Company. Such notice shall set forth the aggregate number of Additional Shares as to which the option is being exercised and the date and time, as reasonably determined by the

Lead Manager, when the Additional Shares are to be delivered (any such date and time being herein sometimes referred to as the “Additional Closing Date”); provided, however, that no Additional Closing Date shall occur earlier than the Closing Date or earlier than the second full business day after the date on which the option shall have been exercised nor later than the eighth full business day after the date on which the option shall have been exercised (unless such time and date are postponed in accordance with the provisions of Section 9 hereof).

Prior to the last date on which an Additional Closing Date, if any, may occur, the Company shall file no further amendment to the Registration Statement or amendment or supplement to the Prospectus to which the Lead Manager shall reasonably object in writing after being furnished in advance a copy thereof and given a reasonable opportunity to review and comment thereon. The Company shall notify the Lead Manager promptly (and, if requested by the Lead Manager, will confirm such notice in writing) (i) when the Registration Statement and any amendments thereto become effective, (ii) of any request by the Commission for any amendment of or supplement to the Registration Statement, the Pricing Prospectus or the Prospectus or for any additional information, (iii) of the Company’s intention to file, or prepare any supplement or amendment to, the Registration Statement, any Preliminary Prospectus, the Pricing Prospectus, the Prospectus or any Free Writing Prospectus, (iv) of the mailing or the delivery to the Commission for filing of any amendment of or supplement to the Registration Statement, the Pricing Prospectus, the Prospectus or any Free Writing Prospectus, including but not limited to a Registration Statement filed pursuant to Rule 462(b) under the Securities Act, (v) the Company’s receipt of notice of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or any post-effective amendment thereto, or suspending the use of any Preliminary Prospectus, the Pricing Prospectus, the Prospectus or any Free Writing Prospectus, or of any examination pursuant to Section 8(e) of the Securities Act concerning the Registration Statement, or, in each case, of the initiation or the threatening of any proceedings therefore, (vi) of the receipt of any comments from the Commission, and (vii) of the receipt by the Company of any notification with respect to the suspension of the qualification of the Shares for sale in any jurisdiction or the initiation or threatening of any proceeding for that purpose. If the Commission shall propose or enter a stop order at any time, the Company will make every reasonable effort to prevent the issuance of any such stop order and, if issued, to obtain the lifting of such order as soon as possible.

(b) The Company shall comply with the Securities Act and the Exchange Act to permit completion of the distribution of the Shares by the Underwriters as contemplated in this Agreement. If at any time when a prospectus relating to the Shares (or, in lieu thereof, the notice referred to in Rule 173(a) under the Securities Act) is required to be delivered under the Securities Act in connection with the sale of the Shares, any event shall have occurred as a result of which the Pricing Disclosure Package (prior to the availability of the Prospectus) or the Prospectus as then amended or supplemented would, in the judgment of the Underwriters or the Company, include an untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances existing at the time of delivery of such Pricing Disclosure Package or Prospectus (or, in lieu thereof, the notice referred to in Rule 173(a) under the Securities Act) to the purchaser, not misleading, or if to comply with the Securities Act, the Exchange Act or the Rules and Regulations it shall be necessary at any time to amend or supplement the Pricing Disclosure Package, the Prospectus or the Registration Statement, the Company will notify the

Lead Manager promptly and prepare and file with the Commission, subject to Section 4(a) hereof, an appropriate amendment, supplement or document (in form and substance reasonably satisfactory to the Lead Manager) that will correct such statement or omission or effect such compliance, and will make every reasonable effort to have any amendment to the Registration Statement declared effective as soon as possible.

(c) The Company will not, without the prior consent of the Lead Manager, (i) make any offer relating to the Shares that would constitute a “free writing prospectus” as defined in Rule 405 under the Securities Act, except for any Issuer Free Writing Prospectus set forth in Schedule III attached hereto and any electronic road show previously approved by the Lead Manager in writing, or (ii) file, refer to, approve, use or authorize the use of any “free writing prospectus” as defined in Rule 405 under the Securities Act with respect to the Offering or the Shares. If at any time any event shall have occurred as a result of which any Issuer Free Writing Prospectus as then amended or supplemented would, in the judgment of the Underwriters or the Company, conflict with the information in the Registration Statement, the Pricing Disclosure Package or the Prospectus as then amended or supplemented or would, in the judgment of the Underwriters or the Company, include an untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances existing at the time of delivery to the purchaser, not misleading, or if to comply with the Securities Act or the Rules and Regulations it shall be necessary at any time to amend or supplement any Issuer Free Writing Prospectus, the Company will notify the Lead Manager promptly and, if requested by the Lead Manager, prepare and furnish without charge to each Underwriter an appropriate amendment or supplement (in form and substance satisfactory to the Lead Manager) that will correct such statement, omission or conflict or effect such compliance.

(d) The Company has complied and will comply with the requirements of Rule 433 with respect to each Issuer Free Writing Prospectus including, without limitation, all prospectus delivery, filing, record retention and legending requirements applicable to each such Issuer Free Writing Prospectus; and the Company has caused there to be made available at least one version of a “bona fide electronic road show” (as defined in Rule 433 under the Securities Act) in a manner that causes the Company not to be required, pursuant to Rule 433(d) under the Securities Act, to file with the Commission any road show.

(e) The Company will promptly deliver to each of the Lead Manager and Paul, Hastings, ▇▇▇▇▇▇▇▇ & ▇▇▇▇▇▇ LLP (“Underwriters’ Counsel”) a signed or conformed copy of the Registration Statement, as initially filed and all amendments thereto, including all consents and exhibits filed therewith, and will maintain in the Company’s files manually signed copies of such documents for at least five years after the date of filing. The Company will promptly deliver to each of the Underwriters such number of copies of any Preliminary Prospectus, the Pricing Prospectus, the Prospectus, the Registration Statement, any Issuer Free Writing Prospectus, and all amendments of and supplements to such documents, if any, as the Lead Manager may reasonably request. As promptly as practicable, but in no event later than 3:00 P.M., New York time, on the business day next succeeding the date of this Agreement, and from time to time thereafter, the Company will furnish the Underwriters with copies of the Prospectus in New York City in such quantities as the Lead Manager may reasonably request.

(f) The Company consents to the use and delivery of the Preliminary Prospectus by the Underwriters in accordance with Rule 430 and Section 5(b) of the Securities Act.

(g) The Company will use its commercially reasonable efforts, in cooperation with the Lead Manager, at or prior to the time of effectiveness of the Registration Statement, to qualify the Shares for offering and sale under the securities laws relating to the offering or sale of the Shares of such jurisdictions, domestic or foreign, as the Lead Manager may reasonably designate, and to maintain such qualification in effect for so long as required for the distribution thereof; except that in no event shall the Company be obligated in connection therewith to become subject to taxation, to qualify as a foreign corporation or to execute a general consent to service of process in any jurisdiction where it is not now so qualified or required to file such consent.

(h) The Company will make generally available to its security holders and the Underwriters as soon as practicable, but in any event not later than 45 days after the end of the first fiscal quarter ending after the first anniversary of the effective date of the Registration Statement (as defined in Rule 158(c) under the Securities Act), a consolidated earnings statement of the Company and the Subsidiaries (which need not be audited) complying with Section 11(a) of the Securities Act and the Rules and Regulations (including, at the option of the Company, Rule 158 under the Securities Act).

(i) During the period beginning on the date of the Prospectus and ending 180 days after the date of the Prospectus (the “Lock-Up Period”), without the prior written consent of the Lead Manager, the Company (i) will not, directly or indirectly, issue, offer, sell, agree to issue, offer or sell, solicit offers to purchase, grant any call option, warrant or other right to purchase, purchase any put option or other right to sell, pledge, borrow or otherwise dispose of any Relevant Security, or make any public announcement of any of the foregoing, (ii) will not establish or increase any “put equivalent position” or liquidate or decrease any “call equivalent position” (in each case within the meaning of Section 16 of the Exchange Act and the rules and regulations promulgated thereunder) with respect to any Relevant Security, and (iii) will not otherwise enter into any swap, derivative or other transaction or arrangement that transfers to another, in whole or in part, any economic consequence of ownership of a Relevant Security, whether or not such transaction is to be settled by delivery of Relevant Securities, other securities, cash or other consideration other than the sale or issuance of Shares as contemplated by this Agreement or the sale or issuance of Relevant Securities: (A) upon the conversion or exchange of convertible or exchangeable securities outstanding on the date hereof; (B) upon the exercise of currently outstanding options; (C) upon the exercise of currently outstanding warrants; and (D) upon the grant and exercise of Shares or options or other equity instruments under, or the issuance and sale of Shares pursuant to, employee stock option plans in effect on the date hereof, each as described in the Registration Statement and the Pricing Disclosure Package (or pursuant to an employee benefit plan assumed by the Company in connection with a transaction described in clause (E) of this sentence); or (E) in connection with any mergers or acquisitions of securities, businesses, property or other assets, joint ventures or other strategic corporate transactions or any other transaction, in each case the primary purpose of which is not to raise capital (provided, however, that in the case of any issuance pursuant to this clause (E), each recipient of any such shares or other securities shall sign and deliver an

agreement in substantially the form of Annex IV attached hereto). During the Lock-Up Period, the Company will not file a registration statement under the Securities Act in connection with any transaction by the Company or any person that is prohibited pursuant to the foregoing, except for registration statements on Form S-8 (including Form S-8/S-3) relating to employee benefit plans or registration statements filed in connection with a transaction contemplated by clause (E) of the preceding paragraph.

The Company will provide the Lead Manager and any co-managers, each officer and director of the Company, and each other stockholder, person and entity listed on Schedule II attached hereto, with prior notice of any such announcement that gives rise to an extension of the Lock-Up Period.

Each of the Company’s officers and directors, and each of the stockholders, optionholders, persons and entities listed on Schedule II attached hereto, have executed a form of agreement in substantially the form attached as Annex IV hereto.

(j) In the event that at any time during the Lock-up Period, any individual not otherwise listed on Schedule II attached hereto becomes subject to Section 16 of the Exchange Act as a result of such individual becoming an officer or director of the Company, then the Company shall, no later than the date such individual becomes an officer or director of the Company, as applicable, obtain a duly executed agreement, in substantially the form attached hereto as Annex IV, from such person and deliver such executed lock-up agreement to the Lead Manager within two business days thereof.

publication or public dissemination by the Company, except as necessary to comply with its obligations under law; provided, however, that if it is necessary for the Lead Manager to disclose such information, the Lead Manager shall provide the Company with notice thereof to enable the Company to seek a protective order and will disclose only such information as necessary to comply with its obligations under law.

(l) The Company will use its commercially reasonable efforts to maintain the quotation of the Shares on the NASDAQ.

(m) The Company will apply the net proceeds from the sale of the Shares as set forth under the caption “Use of Proceeds” in the Registration Statement and the Pricing Disclosure Package.

(o) The Company will use its commercially reasonable efforts to do and perform all things required to be done or performed under this Agreement by the Company prior to the Closing Date or the Additional Closing Date, as the case may be, and to satisfy all conditions precedent to the delivery of the Firm Shares and the Additional Shares.

(q) Unless otherwise agreed to in writing by the Lead Manager, the Company will (i) enforce, to their fullest extent, the lock-up agreement provisions set forth in Section 11 of the Registration Rights Agreement (the “Registration Rights Lock-up”), and (ii) issue stop-transfer instructions to the transfer agent for the Common Stock with respect to any transaction or contemplated transaction that would constitute a breach or violation of, or default under, the Registration Rights Lock-up. In addition, except with the prior written consent of the Lead Manager, the Company agrees not to amend, terminate or waive the Registration Rights Lock-up or release any party to the Registration Rights Agreement from the Registration Rights Lock-up. The Company shall promptly notify each party to the Registration Rights Agreement in the event the restrictions of such Registration Rights Lock-up shall continue to apply beyond the Lock-Up Period (as such term is defined in the Registration Rights Agreement).

(r) Each Underwriter, severally and not jointly, covenants and agrees with the Company that such Underwriter will not use or refer to any “free writing prospectus” (as defined in Rule 405 under the Securities Act) without the prior written consent of the Company if such Underwriter’s use of or reference to such “free writing prospectus” would require the

Company to file with the Commission any “issuer information” (as defined in Rule 433 under the Securities Act).

(s) Concurrently with the Closing, the Company shall file the Restated Certificate of Incorporation with the Secretary of State of the State of Delaware. Prior to the final date on which any Additional Shares may be sold by the Company under this Agreement, the Company shall not restate, amend or otherwise modify the Restated Certificate of Incorporation without the prior written consent of the Lead Manager.

7. Indemnification.

(a) The Company shall indemnify and hold harmless each Underwriter, its affiliates (as such term is defined in Rule 501(b) under the Securities Act) and each person, if any, who controls any Underwriter within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, against any and all losses, liabilities, claims, damages and expenses whatsoever as incurred (including but not limited to reasonable and documented attorneys’ fees and other expenses incurred in investigating, preparing or defending against any litigation, commenced or threatened, or any claim, and any and all amounts paid in settlement of any claim or litigation), joint or several, to which they or any of them may become subject under the Securities Act, the Exchange Act or otherwise, insofar as such losses, liabilities, claims, damages or expenses (or actions in respect thereof) arise out of or are based upon: (i) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, as originally filed or in any amendment thereof or supplement thereto, or the omission or alleged omission to state a material fact in the Registration Statement, as originally filed or in any amendment thereof or supplement thereto, required to be stated therein or necessary to make the statements therein not misleading; or (ii) any untrue statement or alleged untrue statement of a material fact contained in any Issuer Free Writing Prospectus, Preliminary Prospectus, the Pricing Disclosure Package, the Prospectus, any “issuer information” (as defined in Rule 433(h)(2) under the Securities Act) filed or required to be filed pursuant to Rule 433(d) under the Securities Act, or in any of the materials or information set forth on Schedule V attached hereto, or in any supplement to any of the foregoing, or any omission or alleged omission to state a material fact in any of the foregoing necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading; provided, however, that the Company will not be liable in any such case to the extent but only to

the extent that any such loss, liability, claim, damage or expense arises out of or is based upon any such untrue statement or alleged untrue statement or omission or alleged omission made therein in reliance upon and in conformity with written information furnished to the Company by or on behalf of any Underwriter through the Lead Manager expressly for use therein. The parties agree that such information provided by or on behalf of any Underwriter through the Lead Manager consists solely of the material referred to in Section 15 hereof. This indemnity agreement will be in addition to any liability which the Company may otherwise have, including but not limited to other liability under this Agreement.

(b) Each Underwriter, severally and not jointly, shall indemnify and hold harmless the Company, each of the directors of the Company, each of the officers of the Company who shall have signed the Registration Statement, and each other person, if any, who controls the Company within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, against any losses, liabilities, claims, damages and expenses as incurred (including but not limited to reasonable and documented attorneys’ fees and other expenses incurred in investigating, preparing or defending against any litigation, commenced or threatened, or any claim, and any and all amounts paid in settlement of any claim or litigation), joint or several, to which they or any of them may become subject under the Securities Act, the Exchange Act or otherwise, insofar as such losses, liabilities, claims, damages or expenses (or actions in respect thereof) arise out of or are based upon: (i) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, as originally filed or in any amendment thereof or supplement thereto, or the omission or alleged omission to state a material fact in the Registration Statement, as originally filed or in any amendment thereof or supplement thereto, required to be stated therein or necessary to make the statements therein not misleading; (ii) any untrue statement or alleged untrue statement of a material fact contained in any Preliminary Prospectus, the Pricing Disclosure Package or the Prospectus, or any supplement to any of the foregoing, or omission or alleged omission to state a material fact therein-necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading, in each case to the extent, but only to the extent, that any such loss, liability, claim, damage or expense arises out of or is based upon any such untrue statement or alleged untrue statement or omission or alleged omission made therein in reliance upon and in conformity with information furnished in writing to the Company by or on behalf of any Underwriter through the Lead Manager specifically for use therein; provided, however, that in no case shall any Underwriter be liable or responsible under this Section 7 for any amount in excess of the underwriting discount applicable to the Shares to be purchased by such Underwriter hereunder. The parties agree that such information provided by or on behalf of any Underwriter through the Lead Manager consists solely of the material referred to in Section 15 hereof.

(c) The Company also shall indemnify and hold harmless Bear, ▇▇▇▇▇▇▇ & Co. Inc. (“Bear ▇▇▇▇▇▇▇”) and each person, if any, who controls Bear ▇▇▇▇▇▇▇ within the meaning of either Section 15 of the Act, or Section 20 of the Exchange Act, from and against any and all losses, claims, damages, liabilities and judgments incurred as a result of Bear ▇▇▇▇▇▇▇’▇ participation as a “qualified independent underwriter” within the meaning of Rule 2720 of the National Association of Securities Dealers’ Conduct Rules in connection with the Offering, except to the extent any such losses, claims, damages, liabilities and judgments are found in a final judgment by a court of competent jurisdiction (not subject to further appeal) to

have resulted primarily and directly from the gross negligence or willful misconduct of Bear ▇▇▇▇▇▇▇.

(d) Promptly after receipt by an indemnified party under subsection (a), (b) or (c) above of notice of any claims or the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under such subsection, notify each party against whom indemnification is to be sought in writing of the claim or the commencement thereof (but the failure so to notify an indemnifying party shall not relieve the indemnifying party from any liability which it may have under this Section 7 to the extent it is not materially prejudiced as a result thereof through a forfeiture of substantive rights or defenses). In case any such claim or action is brought against any indemnified party, and it notifies an indemnifying party of the commencement thereof, the indemnifying party will be entitled to participate, at its own expense, in the defense of such action, and, to the extent it may elect by written notice delivered to the indemnified party promptly after receiving the aforesaid notice from such indemnified party, to assume and control the defense thereof with counsel satisfactory to such indemnified party; provided, however, that counsel to the indemnifying party shall not (except with the written consent of the indemnified party) also be counsel to the indemnified party. Notwithstanding the foregoing, the indemnified party or parties shall have the right to employ its or their own counsel in any such case, but the fees and expenses of such counsel shall be at the expense of such indemnified party or parties unless (i) the employment of such counsel shall have been authorized in writing by the indemnifying parties in connection with the defense of such action, (ii) the indemnifying parties shall not have employed counsel to have charge of the defense of such action within a reasonable period of time after notice of commencement of the action, (iii) if the indemnified party reasonably determines that the indemnifying party is not diligently defending the action after assumption of the defense, or (iv) such indemnified party or parties shall have reasonably concluded, based on the advice of counsel, that there may be defenses available to it or them which are different from or additional to those available to one or all of the indemnifying parties (in which case the indemnifying parties shall not have the right to direct the defense of such action on behalf of the indemnified party or parties). In the case of any of the events set forth in the preceding sentence, such fees and expenses of not more than one counsel (unless, in connection with any one action or separate but similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances, a conflict or potential conflict exists (based upon advice of counsel to such indemnified party) between such indemnified party and another indemnified party that makes it impossible or inadvisable for the same counsel to conduct the defense of both such indemnified parties) shall be borne by the indemnifying parties. Notwithstanding anything contained in this Agreement to the contrary, if indemnity may be sought pursuant to Section 7(c) hereof in respect of such action or proceeding, then in addition to such separate firm for the indemnified parties, the indemnifying party shall be liable for the reasonable fees and expenses of not more than one separate firm (in addition to any local counsel) for Bear ▇▇▇▇▇▇▇ in its capacity as a “qualified independent underwriter” and all persons, if any, who control Bear ▇▇▇▇▇▇▇ within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act. No indemnifying party shall, without the prior written consent of the indemnified parties, effect any settlement or compromise of, or consent to the entry of judgment with respect to, any pending or threatened claim, investigation, action or proceeding in respect of which indemnity or contribution may be or could have been sought by an indemnified party under this Section 7 or Section 8 hereof (whether or not the indemnified party is an actual or potential party thereto), unless such

settlement, compromise or judgment (i) includes an unconditional release of the indemnified party from all liability arising out of such claim, investigation, action or proceeding and (ii) does not include a statement as to or an admission of fault, culpability or any failure to act, by or on behalf of the indemnified party.

8. Contribution. To the extent the indemnification provided for in Section 7 hereof is for any reason held to be unavailable from any indemnifying party or is insufficient to hold harmless a party indemnified thereunder, the Company, on the one hand, and the Underwriters, on the other hand, shall contribute to the aggregate losses, claims, damages, liabilities and expenses of the nature contemplated by such indemnification provision (including any investigation, legal and other expenses incurred in connection with, and any amount paid in settlement of, any action, suit or proceeding or any claims asserted, but after deducting, in the case of losses, claims, damages, liabilities and expenses suffered by the Company, any contribution received by the Company from persons, other than the Underwriters, who may also be liable for contribution, including persons who control the Company within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, officers of the Company who signed the Registration Statement and directors of the Company) as incurred to which the Company and one or more of the Underwriters may be subject, in such proportions as are appropriate to reflect the relative benefits received by the Company, on the one hand, and the Underwriters, on the other hand, from the Offering or, if such allocation is not permitted by applicable law, in such proportions as are appropriate to reflect not only the relative benefits referred to above but also the relative fault of the Company, on the one hand, and the Underwriters, on the other hand, in connection with the statements or omissions which resulted in such losses, claims, damages, liabilities or expenses, as well as any other relevant equitable considerations. The relative benefits received by the Company, on the one hand, and the Underwriters, on the other hand, shall be deemed to be in the same proportion as (x) the total proceeds from the Offering (net of underwriting discounts and commissions but before deducting expenses) received by the Company bears to (y) the underwriting discount or commissions received by the Underwriters, in each case as set forth in the table on the cover page of the Prospectus. The relative fault of the Company, on the one hand, and of the Underwriters, on the other hand, shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company, on the one hand, or the Underwriters, on the other hand, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company and the Underwriters agree that Bear ▇▇▇▇▇▇▇ will not receive any additional benefits hereunder for serving as the QIU in connection with the Offering, except as provided in Section 7(c) hereof. The Company and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 8 were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to above in this Section 8. The aggregate amount of losses, liabilities, claims, damages and expenses incurred by an indemnified party and referred to above in this Section 8 shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in investigating, preparing or defending against any litigation, or any investigation or proceeding by any judicial, regulatory or other legal or governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue or alleged untrue statement or omission or alleged omission. Notwithstanding the provisions of this

Section 8, (i) no Underwriter shall be required to contribute any amount in excess of the amount by which the discounts and commissions applicable to the Shares underwritten by it and distributed to the public exceeds the amount of any damages which such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission, or alleged omission and (ii) 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. For purposes of this Section 8, each person, if any, who controls an Underwriter within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act shall have the same rights to contribution as such Underwriter, and each person, if any, who controls the Company within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, each officer of the Company who shall have signed the Registration Statement and each director of the Company shall have the same rights to contribution as the Company, subject in each case to clauses (i) and (ii) of the immediately preceding sentence. Any party entitled to contribution will, promptly after receipt of notice of commencement of any action, suit or proceeding against such party in respect of which a claim for contribution may be made against another party or parties, notify each party or parties from whom contribution may be sought, but the omission to so notify such party or parties shall not relieve the party or parties from whom contribution may be sought from any obligation it or they may have under this Section 8 or otherwise to the extent that such party or parties are not materially prejudiced as a result thereof through a forfeiture of substantive rights or defenses. The obligations of the Underwriters to contribute pursuant to this Section 8 are several in proportion to the respective number of Shares to be purchased by each of the Underwriters hereunder and not joint.

9. Underwriter Default.

(a) If any Underwriter or Underwriters shall default in its or their obligation to purchase Firm Shares or Additional Shares hereunder, and if the Firm Shares or Additional Shares with respect to which such default relates (the “Default Shares”) do not (after giving effect to arrangements, if any, made by the Lead Manager pursuant to subsection (b) below) exceed in the aggregate 10% of the number of Firm Shares or Additional Shares, if any, each non-defaulting Underwriter, acting severally and not jointly, agrees to purchase from the Company that number of Default Shares that bears the same proportion of the total number of Default Shares then being purchased as the number of Firm Shares set forth opposite the name of such Underwriter in Schedule I attached hereto bears to the aggregate number of Firm Shares set forth opposite the names of the non-defaulting Underwriters, subject, however, to such adjustments to eliminate fractional shares as the Lead Manager in their sole discretion shall make.

(b) In the event that the aggregate number of Default Shares exceeds 10% of the number of Firm Shares or Additional Shares, as the case may be, the Lead Manager may in their discretion arrange for themselves or for another party or parties (including any non-defaulting Underwriter or Underwriters who so agree) to purchase the Default Shares on the terms contained herein. In the event that within five calendar days after such a default the Lead Manager do not arrange for the purchase of the Default Shares as provided in this Section 9, this Agreement or, in the case of a default with respect to the Additional Shares, the obligations of the Underwriters to purchase and of the Company to sell the Additional Shares shall thereupon

terminate, without liability on the part of the Company with respect thereto (except in each case as provided in Sections 5, 7, 8, 10 and 11) or the Underwriters, but nothing in this Agreement shall relieve a defaulting Underwriter or Underwriters of its or their liability, if any, to the other Underwriters and the Company for damages occasioned by its or their default hereunder.

(c) In the event that any Default Shares are to be purchased by the non-defaulting Underwriters, or are to be purchased by another party or parties as aforesaid, the Lead Manager or the Company shall have the right to postpone the Closing Date or the Additional Closing Date, as the case may be for a period not exceeding five business days, in order to effect whatever changes may thereby be made necessary in the Registration Statement or the Prospectus or in any other documents and arrangements, and the Company agrees to file promptly any amendment of or supplement to the Registration Statement or the Prospectus which, in the opinion of Underwriters’ Counsel, may thereby be made necessary or advisable. The term “Underwriter” as used in this Agreement shall include any party substituted under this Section 9 with like effect as if it had originally been a party to this Agreement with respect to such Firm Shares and Additional Shares.

10. Survival of Representations and Agreements. All representations and warranties, covenants and agreements of the Underwriters and the Company contained in this Agreement or in certificates of officers of the Company or any Subsidiary submitted pursuant hereto, including the agreements contained in Section 5 hereof, the indemnity agreements contained in Section 7 hereof and the contribution agreements contained in Section 8 hereof, shall remain operative and in full force and effect regardless of any investigation made by or on behalf of any Underwriter or any controlling person thereof, or by or on behalf of the Company, any of its officers and directors or any controlling person thereof, and shall survive delivery of and payment for the Shares to and by the Underwriters. The representations contained in Section 1 and the agreements contained in Sections 5, 7, 8, 10 and 11 hereof shall survive any termination of this Agreement, including termination pursuant to Section 9 or 11 hereof.

11. Effective Date of Agreement; Termination.

(a) This Agreement shall become effective when the parties hereto have executed and delivered this Agreement.

(b) The Lead Manager shall have the right to terminate this Agreement at any time prior to the Closing Date or to terminate the obligations of the Underwriters to purchase the Additional Shares at any time prior to the Additional Closing Date, as the case may be, if, at or after the Applicable Time, (i) any domestic or international event or act or occurrence has materially disrupted, or in the opinion of the Lead Manager will in the immediate future materially disrupt, the market for the Company’s securities or securities in general such that, in the sole judgment of the Lead Manager, it is impracticable or inadvisable to proceed with the offering, sale and delivery of the Firm Shares or the Additional Shares, as the case may be, on the terms and in the manner contemplated by this Agreement; or (ii) trading on the NYSE or NASDAQ shall have been suspended or been made subject to material limitations, or minimum or maximum prices for trading shall have been fixed, or maximum ranges for prices for securities shall have been required, on the NYSE or NASDAQ or by order of the Commission or any other governmental authority having jurisdiction; or (iii) a banking moratorium has been declared by

any state or federal authority or any material disruption in commercial banking or securities settlement or clearance services shall have occurred; or (iv)(A) there shall have occurred any outbreak or escalation of hostilities or acts of terrorism involving the United States or there is a declaration of a national emergency or war by the United States or (B) there shall have been any other calamity or crisis or any change in political, financial or economic conditions if the effect of any such event in clause (A) or (B), in the judgment of the Lead Manager, makes it impracticable or inadvisable to proceed with the offering, sale and delivery of the Firm Shares or the Additional Shares, as the case may be, on the terms and in the manner contemplated by this Agreement.

(d) If this Agreement shall be terminated pursuant to any provision of this Agreement (other than pursuant to Section 9(b) hereof), or if the sale of the Shares provided for herein is not consummated because any condition to the obligations of the Underwriters set forth herein is not satisfied or because of any refusal, inability or failure on the part of the Company to perform any agreement herein or comply with any provision hereof, the Company will, subject to demand by the Lead Manager, reimburse the Underwriters for all out-of-pocket expenses (including the reasonable and documented fees, disbursements and expenses of Underwriters’ Counsel), incurred by the Underwriters in connection herewith.

In order to induce you and the other underwriters for which you act as representative (the “Underwriters”) to underwrite the Offering, the undersigned hereby agrees that, without the prior written consent of Bear, ▇▇▇▇▇▇▇ & Co. Inc. (“Bear ▇▇▇▇▇▇▇”), during the period from the date hereof until one hundred eighty (180) days from the date of the final prospectus for the Offering (the “Lock-Up Period”), the undersigned (a) will not, directly or indirectly, offer, sell, agree to offer or sell, solicit offers to purchase, grant any call option or purchase any put option with respect to, pledge, borrow or otherwise dispose of any Relevant Security (as defined below), and (b) will not establish or increase any “put equivalent position” or liquidate or decrease any “call equivalent position” with respect to any Relevant Security (in each case within the meaning of Section 16 of the Securities Exchange Act of 1934, as amended, and the rules and regulations promulgated thereunder), or otherwise enter into any swap, derivative or other transaction or arrangement that transfers to another, in whole or in part, any economic consequence of ownership of a Relevant Security, whether or not such transaction is to be settled by delivery of Relevant Securities, other securities, cash or other consideration. As used herein “Relevant Security” means the Stock, any other equity security of the Company or any of its subsidiaries and any security convertible into, or exercisable or exchangeable for, any Stock or other such equity security.

Notwithstanding the foregoing, the undersigned may transfer Relevant Securities: (a) by bona fide gift; (b) to any trust for the benefit of the undersigned or any parent, grandparent, step parent, step grandparent, mother-in-law, father-in-law, spouse, sibling, sister-in-law, brother-in-law, son-in-law, daughter-in-law, child, step child, grandchild, step grandchild, niece or nephew, including adoptive relationships, of the undersigned; (c) if the undersigned is a partnership, to any general partner, limited partner or affiliate of the undersigned partnership; (d) if the undersigned is a limited liability company, to any member or affiliate of the undersigned limited

In addition, this Agreement shall not restrict the sale or other disposition of Relevant Securities that are acquired by the undersigned in the open market after the Offering is completed, provided that any such sale or other disposition fully complies with, and is not required to be, and will not be, disclosed or reported under, applicable law (including but not limited to Section 16 under the Securities Exchange Act of 1934 and the rules and regulations promulgated thereunder).

Nothing in this Agreement shall restrict the right of the Company to repurchase from the undersigned, or the right of the undersigned to sell or transfer to the Company in connection with any such repurchase right of the Company, shares of Stock issued to the undersigned under the Company’s equity incentive plans which plans are described in the final prospectus for the Offering or under stock option or other equity-based compensation agreements or arrangements entered into by the Company with any of the Company’s employees, directors or consultants pursuant to which such shares of Stock were issued which agreements or arrangements are described in the final prospectus for the Offering. In addition, notwithstanding the lock-up restrictions described in this Agreement, if the undersigned is an officer or director of the Company, the undersigned may, at any time after the closing of the Offering, enter into a written plan meeting the requirements of Rule 10b5-1 under the Securities Exchange Act of 1934, as amended, relating to the sale of shares of Stock, if then permitted by the Company; provided that (i) the shares subject to such plan may not be sold until after the end of the Lock-Up Period (including any extension thereof as provided in this Agreement) and (ii) neither the undersigned nor the Company will make any public announcement, disclosure or filing relating to, or disclosing, such plan or its existence prior to the end of the Lock-Up Period (including any extension thereof as provided in this Agreement).

Notwithstanding the foregoing, if (1) during the last 17 days of the Lock-Up Period, the Company issues an earnings release or discloses material news or a material event relating to the Company occurs; or (2) prior to the expiration of the Lock-Up Period, the Company announces that it will release earnings results or becomes aware that it will disclose material news or that a material event relating to the Company will occur during the 16-day period beginning on the last day of the Lock-Up Period, then the restrictions imposed by this Agreement shall continue to apply until the expiration of the 18-day period beginning on the issuance of the earnings release or the disclosure of the material news or the occurrence of a material event, as applicable, unless such extension is waived, in writing, by Bear ▇▇▇▇▇▇▇. The undersigned acknowledges that the Company will agree, pursuant to an underwriting agreement that the Company proposes to enter into with Bear ▇▇▇▇▇▇▇ on behalf of the several underwriters named therein (“Underwriting

Agreement”), to provide the undersigned with prior notice of any such announcement that gives rise to an extension of the Lock-Up Period, and agrees that any such notice properly delivered will be deemed to have been given to, and received by, the undersigned.

WHEREAS, the undersigned, AEI Holding Corporation is the holder of a warrant (the “Warrant”) to purchase 32,405 shares of the Company’s Series H Preferred Stock (the “Preferred Stock”) issued on November 4, 2005 by the Company in connection with a private offering of the Company’s Series H Preferred Stock;

WHEREAS, in order to induce you and the other underwriters for which you act as representative (the “Underwriters”) to underwrite the Offering, the undersigned has also agreed in a separate lock-up agreement (the “Initial Lock-Up Agreement”) that, without the prior written consent of Bear, ▇▇▇▇▇▇▇ & Co. Inc. (“Bear ▇▇▇▇▇▇▇”), it will not sell, transfer or otherwise dispose of any Relevant Security (as defined in the Initial Lock-Up Agreement) including the Preferred Stock for a period from the date hereof until one hundred eighty (180) days from the date of the final prospectus for the Offering and for such additional period as may be provided for therein; and

WHEREAS, the Preferred Stock has been deemed by the Corporate Finance Department of the National Association of Securities Dealers, Inc.

NOW, THEREFORE, for good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged the undersigned hereby agrees as follows:

No Relevant Security (as defined below) will be sold during the Offering.

During the period from the date hereof until one hundred eighty (180) days immediately following the date of effectiveness of the Offering or commencement of sales of the Offering (“Lock-Up Period”), the undersigned (a) will not, directly or indirectly, offer, sell, agree to offer or sell, solicit offers to purchase, grant any call option or purchase any put option with respect to, transfer, assign, pledge, hypothecate, borrow or otherwise dispose of any Relevant Security (as defined below), and (b) will not establish or increase any “put equivalent position” or liquidate or decrease any “call equivalent position” with respect to any Relevant Security (in each case within the meaning of Section 16 of the Securities Exchange Act of 1934, as amended, and the rules and regulations promulgated thereunder), or otherwise enter into any hedging, short sale, swap, derivative, put or call or other transaction or arrangement that transfers to another, in whole or in part, any economic consequence of ownership of a Relevant Security or results in the effective economic disposition of Relevant Securities by the undersigned, whether or not such transaction is to be settled by delivery of Relevant Securities, other securities, cash or other consideration.
