NOW, THEREFORE, in consideration of the mutual covenants and promises contained in this Agreement and for other good and valuable consideration, the
receipt and adequacy of which are hereby acknowledged, the parties to this Agreement agree as follows:

ARTICLE I

THE OFFER AND MERGER

Section 1.1
The Offer.

(a) Provided that this Agreement shall not have been terminated in accordance with Section 8.1, as promptly as
practicable (and in any event within ten (10) business days) after the date hereof, Purchaser shall (and Parent shall cause Purchaser to) commence (within the meaning of Rule 14d-2 under the Securities Exchange Act of 1934, as amended, and the
rules and regulations promulgated thereunder (the Exchange Act)) the Offer to purchase for cash all Shares at the Offer Price, subject to:

(i) there being validly tendered in the Offer and not withdrawn prior to any then scheduled Expiration Date (as defined below) that number
of Shares which, together with the Shares then beneficially owned by Parent or Purchaser (if any), represents at least a majority of:

(x) all Shares then outstanding, plus

(y) all Shares issuable upon the exercise,
conversion or exchange of any Company Options, SARs, RSUs, Warrants, Equity Interests or other rights to acquire Shares then outstanding that are vested and exercisable, convertible or exchangeable as of any then scheduled Expiration Date or that
would be vested and exercisable, convertible or exchangeable (including after giving effect to the acceleration of any vesting or exercisability, convertibility or exchangeability that may occur as a result of the Offer) at any time within sixty
(60) days following the then scheduled Expiration Date assuming that the holder of such Company Options, SARs, RSUs, Warrants, Equity Interests or other rights satisfies the vesting or exercisability, convertibility or exchangeability
conditions applicable thereto during such time period, less

(z) the number of Shares issuable upon the exercise of
Company Options then outstanding held by Kevin A. DeNuccio which are vested and exercisable as of the then scheduled Expiration Date or that would be vested

and exercisable (including after giving effect to the acceleration of any vesting or exercisability that may occur as a result of the Offer) at any time
within sixty (60) days following the then scheduled Expiration Date assuming that Mr. DeNuccio satisfies the vesting or exercisability conditions applicable thereto during such time period (the Minimum Condition); and

(ii) the satisfaction, or waiver by Parent or Purchaser, of the other conditions and requirements set forth in Annex I.

(b) The obligation of the Purchaser to accept for payment and pay for any Shares validly tendered and not withdrawn pursuant to the Offer
shall be subject to the satisfaction of the Minimum Condition and the satisfaction, or waiver by Parent or Purchaser, of the other conditions and requirements set forth in Annex I. Subject to the prior satisfaction of the Minimum Condition and the
satisfaction or waiver by Parent or Purchaser of the other conditions and requirements set forth in Annex I, Purchaser shall (and Parent shall cause Purchaser to) consummate the Offer in accordance with its terms and accept for payment and pay for
all Shares validly tendered and not withdrawn pursuant to the Offer as promptly as practicable after Purchaser is legally permitted to do so under applicable law. The Offer Price payable in respect of each Share validly tendered and not withdrawn
pursuant to the Offer shall be paid net to the Seller in cash subject to withholding as provide in Section 2.2(e).

(c) The Offer
shall be made by means of an offer to purchase (the Offer to Purchase) that contains the terms set forth in this Agreement, the Minimum Condition and the other conditions and requirements set forth in Annex I. Parent and Purchaser
expressly reserve the right to increase the Offer Price or to make any other changes in the terms and conditions of the offer; provided, however, that unless otherwise provided by this Agreement or as previously approved by the Company
in writing, Purchaser shall not (i) decrease the Offer Price, (ii) change the form of consideration payable in the Offer, (iii) reduce the maximum number of Shares to be purchased in the Offer, (iv) impose conditions to the Offer
that are different than or in addition to the conditions set forth in Annex I, (v) amend or waive the Minimum Condition, (vi) amend any of the conditions to the Offer set forth in Annex I, or (vii) extend the expiration of the Offer
in a manner other than as required by this Agreement.

(d) Unless extended pursuant to and in accordance with the terms of this Agreement,
the Offer shall expire at midnight (New York City time) on the date that is twenty (20) business days (for this purpose calculated in accordance with Rule 14d-1(g)(3) under the Exchange Act) following the commencement (within the meaning of
Rule 14d-2 under the Exchange Act) of the Offer (the Initial Expiration Date) or, in the event the Initial Expiration Date has been extended pursuant to and in accordance with this Agreement, the date to which the Offer has been
so extended (the Initial Expiration Date, or such later date to which the Initial Expiration Date has been extended pursuant to and in accordance with this Agreement, is referred to as the Expiration Date).

---

(e) The Offer shall be extended from time to time as follows:

(i) Offer Conditions Not Satisfied. If on or prior to any then scheduled Expiration Date, all of the conditions to the Offer
(including the Minimum Condition and all other conditions and requirements set forth in Annex I) shall not have been satisfied, or waived by Parent or Purchaser if permitted hereunder, Purchaser shall (and Parent shall cause Purchaser to) extend the
Offer for successive periods of ten (10) business days each in order to permit the satisfaction of such conditions, or any lesser period ending on April 19, 2007 (the Initial Outside Date), or on December 19, 2007
in the event that the HSR Condition and/or the Governmental Approval Condition shall not have been satisfied, or waived by Parent and Purchaser if permitted hereunder, by the Initial Outside Date (the Extended Outside Date), if
any such ten-day extension would otherwise end after the Initial Outside Date or the Extended Outside Date, as applicable.

(ii) Required by Applicable Law or Nasdaq. Purchaser shall extend the Offer for any period or periods required by applicable law, rule, regulation, interpretation or position of the SEC (or its staff) or Nasdaq.

(f) If necessary to obtain sufficient Shares (without regard to the exercise of the 90% Top-Up Option) to reach the Short Form Threshold, Purchaser may,
in its sole discretion, provide for a subsequent offering period in accordance with Rule 14d-11 under the Exchange Act. In the event that more than eighty percent (80%) of the then outstanding Shares have been validly tendered and
not withdrawn pursuant to the Offer following the Expiration Date, Purchaser shall (and Parent shall cause Purchaser to) provide for a subsequent offering period in accordance with Rule 14d-11 under the Exchange Act of at least ten
(10) business days immediately following the Expiration Date unless Parent and Purchaser exercise the 90% Top-Up Option. Subject to the terms and conditions of this Agreement and the Offer, Purchaser shall (and Parent shall cause Purchaser to)
accept for payment, and pay for, all Shares that are validly tendered and not withdrawn pursuant to the Offer during such subsequent offering period promptly after any such Shares are tendered during such subsequent offering
period. The Offer Documents will provide for the possibility of a subsequent offering period in a manner consistent with the terms of this Section 1.1(f).

(g) Purchaser shall not terminate the Offer prior to any scheduled Expiration Date without the prior written consent of the Company except in the event
that this Agreement is terminated pursuant to Section 8.1. In the event that this Agreement is terminated pursuant to Section 8.1, Purchaser shall (and Parent shall cause Purchaser to) promptly (and in any event within twenty four
(24) hours of such termination), irrevocably and unconditionally terminate the Offer.

(h) As soon as practicable after the
commencement of the Offer (within the meaning of Rule 14d-2 under the Exchange Act), Parent and Purchaser shall file with the Securities and Exchange Commission (the SEC), pursuant to Regulation M-A under the Exchange Act
(Regulation M-A), a Tender Offer Statement on Schedule TO with respect to the Offer (together with all amendments, supplements and exhibits thereto, the Schedule TO). The Schedule TO shall include, as exhibits,
the



4



---

Offer to Purchase and a form of letter of transmittal and summary advertisement (collectively, together with any amendments and supplements thereto, the
Offer Documents). Parent and Purchaser agree to take all steps necessary to cause the Offer Documents to be filed with the SEC and disseminated to holders of Shares, in each case as and to the extent required by the Exchange Act.
Parent and Purchaser, on the one hand, and the Company, on the other hand, agree to promptly correct any information provided by it for use in the Offer Documents if and to the extent that it shall have become false or misleading in any material
respect or as otherwise required by applicable law. Parent and Purchaser further agree to take all steps necessary to cause the Offer Documents, as so corrected (if applicable), to be filed with the SEC and disseminated to holders of Shares, in each
case as and to the extent required by the Exchange Act. The Company and its counsel shall be given a reasonable opportunity to review the Schedule TO and the Offer Documents before they are filed with the SEC, and Parent and Purchaser shall give due
consideration to all the reasonable additions, deletions or changes suggested thereto by the Company and its counsel. In addition, Parent and Purchaser shall provide the Company and its counsel with copies of any written comments, and shall inform
them of any oral comments, that Parent, Purchaser or their counsel may receive from time to time from the SEC or its staff with respect to the Schedule TO or the Offer Documents promptly after receipt of such comments, and any written or oral
responses thereto. The Company and its counsel shall be given a reasonable opportunity to review any such written responses and Parent and Purchaser shall give due consideration to all reasonable additions, deletions or changes suggested thereto by
the Company and its counsel. If the Offer is terminated or withdrawn by Purchaser, or this Agreement is terminated prior to the purchase of Shares in the Offer, Purchaser shall promptly return, and shall cause any depository, acting on behalf of
Purchaser to return, all tendered Shares to the registered holders thereof.

(i) The Offer Price shall be adjusted appropriately to reflect
the effect of any stock split, reverse stock split, stock dividend (including any dividend or distribution of securities convertible into Common Stock), cash dividend, reorganization, recapitalization, reclassification, combination, exchange of
shares or other like change with respect to Common Stock occurring on or after the date hereof and prior to the Effective Time.

Section 1.2 Company Actions.

(a) Contemporaneous with the filing of the Schedule TO, the Company shall, in a manner
that complies with Rule 14d-9 under the Exchange Act, file with the SEC a Tender Offer Solicitation/ Recommendation Statement on Schedule 14D-9 with respect to the Offer (together with all amendments, supplements and exhibits thereto, the
Schedule 14D-9) that shall, subject to the provisions of Section 5.3(c), contain the Company Recommendation. The Company further agrees to take all steps necessary to cause the Schedule 14D-9 to be filed with the SEC and
disseminated to holders of Shares, in each case as and to the extent required by the Exchange Act. The Company, on the one hand, and Parent and Purchaser, on the other hand, agree to promptly correct any information provided by it for use in the
Schedule 14D-9 if and to the extent that it shall have become false or misleading in any material respect or as



5

otherwise required by applicable law. The Company further agrees to take all steps necessary to cause the Schedule 14D-9, as so corrected (if applicable), to
be filed with the SEC and disseminated to holders of Shares, in each case as and to the extent required by the Exchange Act. Parent, Purchaser and their counsel shall be given a reasonable opportunity to review the Schedule 14D-9 before it is filed
with the SEC and the Company shall give due consideration to all reasonable additions, deletions or changes suggested thereto by Parent, Purchaser and their counsel. In addition, the Company shall provide Parent, Purchaser and their counsel with
copies of any written comments, and shall inform them of any oral comments, that the Company or its counsel may receive from time to time from the SEC or its staff with respect to the Schedule 14D-9 promptly after the Companys receipt of such
comments, and any written or oral responses thereto. Parent, Purchaser and their counsel shall be given a reasonable opportunity to review any such written responses and the Company shall give due consideration to all reasonable additions, deletions
or changes suggested thereto by Parent, Purchaser and their counsel.

(b) In connection with the Offer, the Company shall promptly furnish
or cause to be furnished to Purchaser mailing labels, security position listings and any available listing or computer files containing the names and addresses of the record holders of the Shares as of the most recent practicable date, and shall
promptly furnish Purchaser with such information and assistance (including, but not limited to, lists of holders of the Shares, updated promptly from time to time upon Purchasers request, and their addresses, mailing labels and lists of
security positions) as Purchaser or its agent may reasonably request for the purpose of communicating the Offer to the record and beneficial holders of the Shares. Except for such steps as are necessary to disseminate the Offer Documents and any
other documents necessary to consummate the Offer, the Merger and the other Transactions contemplated by this Agreement, Purchaser shall hold in confidence the information contained in any such labels, listings and files, shall use such information
only in connection with the Offer and the Merger and, if this Agreement shall be terminated, shall promptly deliver to the Company all copies of such information.

Section 1.3 Directors.

(a) Promptly after Purchaser accepts for payment and pays for any Shares
tendered and not withdrawn pursuant to the Offer (the Appointment Time), and at all times thereafter, Purchaser shall be entitled to elect or designate such number of directors, rounded up to the next whole number, on the Company
Board of Directors as is equal to the product of the total number of directors on the Company Board of Directors (giving effect to the directors elected or designated by Purchaser pursuant to this sentence) multiplied by the percentage that the
aggregate number of Shares beneficially owned by Parent, Purchaser and any of its affiliates bears to the total number of Shares then outstanding. The Company shall, upon Purchasers request at any time following the purchase of and payment for
Shares pursuant to the Offer, take such actions, including but not limited to promptly filling vacancies or newly created directorships on the Company Board of Directors, promptly increasing the size of the Company Board of Directors (including by
amending the Bylaws of the Company if necessary so as to increase the size of the Company Board of Directors) and/or promptly securing the resignations of such number of its incumbent directors as are necessary or desirable to

enable Purchasers designees to be so elected or designated to the Company Board of Directors, and shall use its best efforts to cause Purchasers
designees to be so elected or designated at such time. The Company shall, upon Purchasers request following the Appointment Time, also cause Persons elected or designated by Purchaser to constitute the same percentage (rounded up to the next
whole number) as is on the Company Board of Directors of (i) each committee of the Company Board of Directors, (ii) each board of directors (or similar body) of each Company Subsidiary and (iii) each committee (or similar body) of
each such board, in each case to the extent permitted by applicable law and the Marketplace Rules of the Nasdaq Global Market (the Nasdaq). Promptly after the Appointment Time, the Company shall take all action necessary to elect
to be treated as a controlled company as defined by Nasdaq Marketplace Rule 4350(c) and make all necessary filings and disclosures associated with such status. The Companys obligations under this Section 1.3(a) shall be
subject to Section 14(f) of the Exchange Act and Rule 14f-1 promulgated thereunder. The Company shall promptly upon execution of this Agreement take all actions required pursuant to Section 14(f) and Rule 14f-1 in order to fulfill its
obligations under this Section 1.3(a), including mailing to stockholders (together with the Schedule 14D-9) the information required by Section 14(f) and Rule 14f-1 as is necessary to enable Purchasers designees to be elected or
designated to the Company Board of Directors. Purchaser shall supply the Company with information with respect to Purchasers designees and Parents and Purchasers respective officers, directors and affiliates to the extent required
by Section 14(f) and Rule 14f-1. The provisions of this Section 1.3(a) are in addition to and shall not limit any rights that any of Purchaser, Parent or any of their respective affiliates may have as a record holder or beneficial owner of
Shares as a matter of applicable law with respect to the election of directors or otherwise.

(b) In the event that Purchasers
designees are elected or designated to the Company Board of Directors pursuant to Section 1.3(a), then, until the Effective Time, the Company shall cause the Company Board of Directors to maintain three (3) directors who are members of the
Company Board of Directors on the date hereof, each of whom shall be an independent director as defined by Rule 4200(a)(15) of the Nasdaq Marketplace Rules and eligible to serve on the Companys audit committee under the Exchange
Act and Nasdaq rules and, at least one of whom shall be an audit committee financial expert as defined in Item 401(h) of Regulation S-K and the instructions thereto (the Continuing Directors); provided,
however, that if any Continuing Director is unable to serve due to death, disability or resignation, the Company shall take all necessary action (including creating a committee of the Company Board of Directors) so that the Continuing
Director(s) shall be entitled to elect or designate another Person (or Persons) to fill such vacancy, and such Person (or Persons) shall be deemed to be a Continuing Director for purposes of this Agreement. If no Continuing Director then remains,
the other directors shall designate three (3) Persons to fill such vacancies and such Persons shall be deemed Continuing Directors for all purposes of this Agreement. Notwithstanding anything in this Agreement to the contrary, if
Purchasers designees constitute a majority of the Company Board of Directors after the Appointment Time and prior to the Effective Time, then the affirmative vote of a majority of the Continuing Directors shall (in addition to the approval
rights of the Company Board of Directors or the stockholders of the Company as may be required by the Amended and Restated

Certificate of Incorporation of the Company (as amended, the Company Certificate), the Amended and Restated Bylaws of the Company (as
amended, the Company Bylaws, and together with the Company Certificate, the Company Governing Documents) or applicable law) be required (i) for the Company to amend or terminate this Agreement, (ii) to
exercise or waive any of the Companys rights, benefits or remedies hereunder, if such action would materially and adversely affect the holders of Shares (other than Parent or Purchaser), (iii) to amend the Company Governing Documents if
such action would materially and adversely affect the holders of Shares (other than Parent or Purchaser) or (iv) to take any other action of the Company Board of Directors under or in connection with this Agreement if such action would
materially and adversely affect the holders of Shares (other than Parent or Purchaser); provided, however, that if there shall be no Continuing Directors as a result of such Persons deaths, disabilities or refusal to serve, then
such actions may be effected by majority vote of the entire Company Board of Directors.

ARTICLE II

CONVERSION OF SECURITIES

Section 2.1
Conversion of Capital Stock. At the Effective Time, by virtue of the Merger and without any action on the part of the holders of any securities of the Company or common stock, par value $0.0001 per share, of Purchaser (the Purchaser
Common Stock):

(a) Purchaser Common Stock. Each issued and outstanding share of Purchaser Common Stock shall be converted
into and become one fully paid and nonassessable share of common stock, par value $0.0001 per share, of the Surviving Corporation.

(b)
Cancellation of Treasury Stock and Parent-Owned Stock. All Shares that are owned by the Company and any Shares owned by Parent, Purchaser or any of their respective subsidiaries or affiliates shall be cancelled and shall cease to exist, and
no consideration shall be delivered in exchange therefor.

(c) Conversion of Common Stock. Each issued and outstanding Share (other
than Shares to be cancelled in accordance with Section 2.1(b) and other than Dissenting Shares) shall be converted into the right to receive the Offer Price, payable to the holder thereof in cash, without interest (the Merger
Consideration). From and after the Effective Time, all such Shares shall no longer be outstanding and shall automatically be cancelled and shall cease to exist, and each holder of a certificate representing any such Shares shall cease to
have any rights with respect thereto, except the right to receive the Merger Consideration therefor upon the surrender of such certificate in accordance with Section 2.2, without interest thereon.



11



---

(d) Adjustment to Merger Consideration. The Merger Consideration shall be adjusted appropriately
to reflect the effect of any stock split, reverse stock split, stock dividend (including any dividend or distribution of securities convertible into Common Stock), cash dividend, reorganization, recapitalization, reclassification, combination,
exchange of shares or other like change with respect to Common Stock occurring on or after the date hereof and prior to the Effective Time.

Section 2.2 Exchange of Certificates.

(a) Paying Agent. Purchaser shall designate a bank or trust company to
act as the payment agent in connection with the Merger (the Paying Agent). Prior to the Effective Time, Parent or Purchaser shall deposit, or cause to be deposited, with the Paying Agent the aggregate Merger Consideration. Such
funds shall be invested by the Paying Agent as directed by Parent, in its sole discretion, pending payment thereof by the Paying Agent to the holders of the Shares. Earnings from such investments shall be the sole and exclusive property of Parent,
and no part of such earnings shall accrue to the benefit of holders of Shares.

(b) Exchange Procedures. Promptly after the
Effective Time, the Paying Agent shall mail to each holder of record of a certificate or certificates which immediately prior to the Effective Time represented outstanding Shares (the Certificates) and whose Shares were converted
pursuant to Section 2.1 into the right to receive the Merger Consideration (i) a letter of transmittal (which shall specify that delivery shall be effected, and risk of loss and title to the Certificates shall pass, only upon delivery of
the Certificates to the Paying Agent and shall be in such form and have such other provisions as Parent may reasonably specify) and (ii) instructions for effecting the surrender of the Certificates in exchange for payment of the Merger
Consideration. Upon surrender of a Certificate for cancellation to the Paying Agent or to such other agent or agents as may be appointed by Parent, together with such letter of transmittal, duly executed, the holder of such Certificate shall be
entitled to receive in exchange therefor the Merger Consideration for each Share formerly represented by such Certificate and the Certificate so surrendered shall forthwith be cancelled. If payment of the Merger Consideration is to be made to a
Person other than the Person in whose name the surrendered Certificate is registered, it shall be a condition precedent of payment that (x) the Certificate so surrendered shall be properly endorsed or shall be otherwise in proper form for
transfer and (y) the Person requesting such payment shall have paid any transfer and other similar taxes required by reason of the payment of the Merger Consideration to a Person other than the registered holder of the Certificate surrendered
or shall have established to the satisfaction of the Surviving Corporation that such tax either has been paid or is not required to be paid. Until surrendered as contemplated by this Section 2.2, each Certificate shall be deemed at any time
after the Effective Time to represent only the right to receive the Merger Consideration in cash as contemplated by this Section 2.2, without interest thereon.

(c) Transfer Books; No Further Ownership Rights in Shares. At the Effective Time, the stock transfer books of the Company shall be closed and thereafter there shall be no further registration of transfers of
Shares on the records of the Company.



12



---

From and after the Effective Time, the holders of Certificates outstanding immediately prior to the Effective Time shall cease to have any rights with
respect to such Shares except as otherwise provided for herein or by applicable law. If, after the Effective Time, Certificates are presented to the Surviving Corporation for any reason, they shall be cancelled and exchanged as provided in this
Article II.

(d) Termination of Fund; No Liability. At any time following six months after the Effective Time, the Surviving
Corporation shall be entitled to require the Paying Agent to deliver to it any funds (including any interest received with respect thereto) made available to the Paying Agent and not disbursed (or for which disbursement is pending subject only to
the Paying Agents routine administrative procedures) to holders of Certificates, and thereafter such holders shall be entitled to look only to the Surviving Corporation (subject to abandoned property, escheat or other similar laws) only as
general creditors thereof with respect to the Merger Consideration payable upon due surrender of their Certificates, without any interest thereon. Notwithstanding the foregoing, neither the Surviving Corporation nor the Paying Agent shall be liable
to any holder of a Certificate for Merger Consideration delivered to a public official pursuant to any applicable abandoned property, escheat or similar law.

(e) Withholding Rights. Parent, Purchaser, the Surviving Corporation and the Paying Agent, as the case may be, shall be entitled to deduct and withhold from the relevant Merger Consideration or Offer Price
otherwise payable pursuant to this Agreement to any holder of Shares such amounts that Parent, Purchaser, the Surviving Corporation or the Paying Agent is required to deduct and withhold with respect to the making of such payment under the Internal
Revenue Code of 1986, as amended (the Code), the rules and regulations promulgated thereunder or any provision of applicable state, local or foreign law. To the extent that amounts are so withheld by Parent, Purchaser, the
Surviving Corporation or the Paying Agent, such amounts shall be treated for all purposes of this Agreement as having been paid to the holder of Shares in respect of which such deduction and withholding was made by Parent, Purchaser, the Surviving
Corporation or the Paying Agent.

(f) Lost, Stolen or Destroyed Certificates. In the event that any Certificates shall have been
lost, stolen or destroyed, the Paying Agent shall issue in exchange for such lost, stolen or destroyed Certificates, upon the making of an affidavit of that fact by the holder thereof, the Merger Consideration payable in respect thereof pursuant to
Section 2.1 hereof; provided, however, that Parent may, in its discretion and as a condition precedent to the payment of such Merger Consideration, require the owners of such lost, stolen or destroyed Certificates to deliver a
bond in such sum as it may reasonably direct as indemnity against any claim that may be made against Parent, the Surviving Corporation or the Paying Agent with respect to the Certificates alleged to have been lost, stolen or destroyed.

Section 2.3 Dissenting Shares.

(a) Notwithstanding anything in this Agreement to the contrary, Shares outstanding immediately prior to the Effective Time and held by a holder who is



13



---

entitled to demand and properly demands appraisal of such Shares (Dissenting Shares) pursuant to, and who complies in all respects with,
Section 262 of the DGCL (the Appraisal Rights) shall be entitled to payment of the fair value of such Dissenting Shares in accordance with the Appraisal Rights; provided, however, that if any such holder shall
fail to perfect or otherwise shall waive, withdraw or lose the right to dissent under the Appraisal Rights, then the right of such holder to be paid the fair value of such holders Dissenting Shares shall cease and such Dissenting Shares shall
be deemed to have been converted as of the Effective Time into, and to have become exchangeable solely for the right to receive the Merger Consideration.

(b) The Company shall serve prompt notice to Purchaser of any demands received by the Company for dissenters rights of any Shares, and Purchaser shall have the right to participate in all negotiations and
proceedings with respect to such demands. Prior to the Effective Time, the Company shall not, without the prior written consent of Purchaser, make any payment with respect to, or settle or compromise or offer to settle or compromise, any such
demand, or agree to do any of the foregoing.

Section 2.4 Top-Up Options.

(a) 90% Top-Up Option.

(i) The Company hereby grants to Purchaser an irrevocable option (the 90% Top-Up Option), exercisable only upon the terms and subject to the conditions set forth herein, to purchase with a promissory note, bearing simple
interest at 6% per annum, and due 30 days after the purchase (a Promissory Note), at a price per share equal to the Offer Price, that number of shares of Common Stock (the 90% Top-Up Option Shares) equal to
the lesser of (x) the lowest number of shares of Common Stock that, when added to the number of shares of Common Stock owned by Parent, Purchaser and their respective subsidiaries and affiliates at the time of such exercise, shall constitute
ten thousand (10,000) shares more than 90% of the shares of Common Stock then outstanding (after giving effect to the issuance of the 90% Top-Up Option Shares) and (y) an aggregate number of shares of Common Stock that is equal to 19.9% of
the shares of Common Stock issued and outstanding as of the date hereof; provided, however, that the 90% Top-Up Option shall not be exercisable unless, immediately after such exercise and the issuance of shares of Common Stock pursuant
thereto, the Short Form Threshold would be reached (assuming the issuance of the 90% Top-Up Option Shares); and provided,further, that in no event shall the 90% Top-Up Option be exercisable for a number of shares of Common
stock in excess of the Companys total authorized and unissued shares of Common Stock.

(ii) Provided that no
applicable law, rule, regulation, order, injunction or other legal impediment shall prohibit the exercise of the 90% Top-Up Option or the issuance of the 90% Top-Up Option Shares pursuant thereto, or otherwise make such exercise or issuance illegal,
Purchaser may exercise the 90% Top-Up Option, in whole but not in part, at any one time after the Appointment Time and prior to the earlier to occur of (i) the Effective Time and (ii) the termination of this Agreement pursuant to
Section 8.1.



14



---

(iii) In the event Purchaser wishes to exercise the 90% Top-Up Option, Purchaser shall
send to the Company a written notice (a 90% Top-Up Exercise Notice, the date of which notice is referred to herein as the 90% Top-Up Notice Date) specifying the denominations of the certificate or certificates
evidencing the 90% Top-Up Option Shares which the Purchaser wishes to receive, and the place, time and date for the closing of the purchase and sale pursuant to the 90% Top-Up Option (the 90% Top-Up Closing). The Company shall,
promptly after receipt of the 90% Top-Up Exercise Notice, deliver a written notice to the Purchaser confirming the number of 90% Top-Up Option Shares and the aggregate purchase price therefore (the 90% Top-Up Notice Receipt). At
the 90% Top-Up Closing, Purchaser shall pay the Company the aggregate price required to be paid for the 90% Top-Up Option Shares, by delivery of a Promissory Note in an aggregate principal amount equal to the amount specified in the 90% Top-Up
Notice Receipt, and the Company shall cause to be issued to Purchaser a certificate or certificates representing the 90% Top-Up Option Shares. Such certificates may include any legends that are required by federal or state securities laws.

(b) 50% Top-Up Option.

(i) In order to offset the dilutive impact of the issuance of Shares pursuant to the exercise, conversion or exchange of any Company Options, SARs, RSUs, Warrants, Equity Interests or other rights to acquire Shares
following the Appointment Time, the Company hereby grants to Purchaser an irrevocable option (the 50% Top-Up Option), exercisable only upon the terms and subject to the conditions set forth herein, to purchase with a Promissory
Note, at a price per share equal to the Offer Price, that number of shares of Common Stock (the 50% Top-Up Option Shares) equal to the lesser of (x) the lowest number of shares of Common Stock that, when added to the number
of shares of Common Stock owned by Parent, Purchaser and their respective subsidiaries and affiliates at the time of such exercise, shall constitute ten thousand (10,000) shares more than 50% of the shares of Common Stock then outstanding
(after giving effect to the issuance of the 50% Top-Up Option Shares) and (y) an aggregate number of shares of Common Stock that is equal to 19.9% of the shares of Common Stock issued and outstanding as of the date hereof; provided,
however, that the 50% Top-Up Option shall not be exercisable unless, immediately after such exercise and the issuance of shares of Common Stock pursuant thereto, Purchaser would own more than 50% of the Shares then outstanding (assuming the
issuance of the 50% Top-Up Option Shares); and provided,further, that in no event shall the 50% Top-Up Option be exercisable for a number of shares of Common stock in excess of the Companys total authorized and unissued
shares of Common Stock.



15



---

(ii) Provided that no applicable law, rule, regulation, order, injunction or other legal
impediment shall prohibit the exercise of the 50% Top-Up Option or the issuance of the 50% Top-Up Option Shares pursuant thereto, or otherwise make such exercise or issuance illegal, Purchaser may exercise the 50% Top-Up Option, in whole but not in
part, at any one time after the Appointment Time and prior to the earlier to occur of (i) the record date for the Special Meeting, and (ii) the termination of this Agreement pursuant to Section 8.1.

(iii) In the event Purchaser wishes to exercise the 50% Top-Up Option, Purchaser shall send to the Company a written notice (a
50% Top-Up Exercise Notice, the date of which notice is referred to herein as the 50% Top-Up Notice Date) specifying the denominations of the certificate or certificates evidencing the 50% Top-Up Option Shares
which the Purchaser wishes to receive, and the place, time and date for the closing of the purchase and sale pursuant to the 50% Top-Up Option (the 50% Top-Up Closing). The Company shall, promptly after receipt of the 50% Top-Up
Exercise Notice, deliver a written notice to the Purchaser confirming the number of 50% Top-Up Option Shares and the aggregate purchase price therefore (the 50% Top-Up Notice Receipt). At the 50% Top-Up Closing, Purchaser shall
pay the Company the aggregate price required to be paid for the 50% Top-Up Option Shares by delivery of a Promissory Note in an aggregate principal amount equal to the aggregate purchase price specified in the 50% Top-Up Notice Receipt, and the
Company shall cause to be issued to Purchaser a certificate or certificates representing the 50% Top-Up Option Shares. Such certificates may include any legends that are required by federal or state securities laws.

Section 2.5 Treatment of Options, Restricted Stock and other Equity Awards.

(a) At the Effective Time, each option, or portion thereof, to purchase Shares granted pursuant to the Company Stock Plans (Company
Options) or stock appreciation right, or portion thereof, whether settled in cash or Shares (SAR), in each case granted pursuant to the Company Stock Plans, that is outstanding and vested immediately prior to the
Effective Time, shall be deemed exercised and automatically converted into the right to receive an amount in cash equal to the product obtained by multiplying (x) the aggregate number of Shares for which such Company Option or SAR was vested
and exercisable immediately prior to the Effective Time and (y) the excess, if any, of the Merger Consideration less the per Share exercise price of such Company Option or SAR (the Option Consideration) after which it shall
be cancelled and extinguished.

(b) At the Effective Time, each Company Option and SAR that was outstanding and unvested immediately prior
to the Effective Time shall be assumed by the Parent and converted into the right to receive the Option Consideration, provided that the Company Option or SAR shall be subject to the same vesting arrangements that were applicable to such Company
Option or SAR immediately prior to the Effective Time and Parents obligation to pay the Option Consideration will only become payable to the



16



---

extent that such vesting requirements are satisfied. For each Share subject to a Company Option or SAR which would have vested after the Effective Time under
the vesting schedule applicable to such Company Option or SAR immediately prior to the Effective Time, the holder thereof shall be entitled to a cash payment equal to the Option Consideration, and Parent shall pay the holder thereof the Option
Consideration as soon as administratively practicable after the day on which such Share would have vested.

(c) At the Effective Time, the
Merger Consideration payable with respect to each unvested Share subject to restrictions and forfeiture granted pursuant to the Company Stock Plans (Restricted Stock) shall be subject to the same restrictions and vesting
arrangements that were applicable to such unvested Restricted Stock immediately prior to the Effective Time. Therefore, cash otherwise payable pursuant to Section 2.1 in exchange for the Restricted Stock issued and outstanding immediately prior
to the Effective Time (Unvested Cash) shall not automatically be payable by Parent at the Effective Time, and shall instead become payable by Parent on the date that such Shares of Restricted Stock would have become vested under
the vesting schedule in place for such shares immediately prior to or at the Effective Time (subject to the restrictions and other terms of such vesting schedule). Parent shall make all such required payments to holders of Unvested Cash as soon as
administratively practicable after the day on which such Unvested Cash would have become vested under the original vesting schedule. All outstanding rights to repurchase Restricted Stock that the Company may hold or similar restrictions in the
Companys favor immediately prior to the Effective Time (all such rights, the Repurchase Rights) shall be assigned to Parent in the Merger and shall thereafter be exercisable by Parent upon the same terms and subject to the
same conditions that were in effect immediately prior to the Effective Time, except that Repurchase Rights may be exercised by Parent retaining the Unvested Cash into which such Restricted Stock has been converted, and paying to the former holder
thereof the repurchase price in effect for each such Share subject to that Repurchase Right immediately prior to the Effective Time.

(d)
At the Effective Time, each Share subject to a Restricted Stock Unit granted pursuant to the Company Stock Plans (RSU) that is outstanding immediately prior to the Effective Time will be assumed by the Parent and converted into
the potential right to receive a cash payment equal to the Merger Consideration (the RSU Consideration); provided, however, that the RSU shall be subject to the same vesting arrangements that were applicable immediately prior to
the Effective Time and payment of the RSU Consideration with respect to a Share subject to an RSU will only become payable by the Parent to the extent that such vesting requirements are satisfied. For each Share subject to an RSU which would have
vested after the Effective Time, the holder thereof shall be entitled to a cash payment equal to the RSU Consideration, and Parent shall pay the holder thereof the RSU Consideration as soon as administratively practicable after the day on which such
Share subject to the RSU would have vested.

evidencing the Company Options, SARs Restricted Stock and RSUs. All amounts payable pursuant to Sections 2.5(a)-(d) shall be paid without interest, and
no Unvested Cash or RSU Consideration or rights to receive any payments pursuant to Section 2.5(c) and (d) may be pledged, encumbered, sold, assigned or transferred (including any transfer by operation of law), by any Person, other than
Parent, or be taken or reached by any legal or equitable process in satisfaction of any liability of such Person, prior to the distribution to such Person of such Unvested Cash or RSU Consideration or payment pursuant to Section 2.5(c) and (d),
in accordance with this Agreement. Any payments made pursuant to this Section 2.5 shall be net of all applicable withholding taxes that Parent, Purchaser, the Surviving Corporation and the Paying Agent, as the case may be, shall be required to
deduct and withhold from the relevant Option Consideration, Unvested Cash, RSU Consideration, or Merger Consideration under the Code, the rules and regulations promulgated thereunder or any provision of applicable state, local or foreign law. To the
extent that amounts are so withheld by Parent, Purchaser, the Surviving Corporation or the Paying Agent, such amounts shall be treated for all purposes of this Agreement as having been paid to the holder of Shares in respect of which such deduction
and withholding was made by Parent, Purchaser, the Surviving Corporation or the Paying Agent.

Section 2.6 Treatment of Employee
Stock Purchase Plan. Each outstanding purchase right (each, a Purchase Right) under the Companys 1999 Employee Stock Purchase Plan (the ESPP) shall be cancelled immediately prior to the Effective Time
and converted into the right to receive at the Effective Time from Parent, an amount (subject to any withholding tax required by applicable law) in cash equal to the product obtained by multiplying (x) the number of Shares issuable to the
holder of such Purchase Right had such Purchase Right been exercised immediately prior to the Effective Time and (y) the amount by which the Merger Consideration exceeds the purchase price under such Purchase Right. Within five (5) days
following the Effective Time, Parent shall cause the Company to return to participants their respective accumulated payroll contributions not applied to the purchase of Shares under the ESPP, if any.

Section 2.7 Treatment of Warrants. At the Effective Time, each warrant to purchase Shares (the Warrants) that is issued
and outstanding immediately prior to the Effective Time and not terminated pursuant to its terms shall be assumed by Parent and converted into the right to receive cash equal to the product obtained by multiplying (x) the aggregate number of
Shares for which such Warrant was exercisable immediately prior to the Effective Time and (y) the excess, if any, of the Merger Consideration less the per Share exercise price of such Warrant (the Warrant Consideration). The
Company shall take all necessary actions, including obtaining any required consents from holders of outstanding Warrants necessary to effect such assumption pursuant to the terms of the applicable Warrant. Any payments made pursuant to this
Section 2.7 shall be net of all applicable withholding taxes that Parent, Purchaser, the Surviving Corporation and the Paying Agent, as the case may be, shall be required to deduct and withhold from the Warrant Consideration under the Code, the
rules and regulations promulgated thereunder or any provision of applicable state, local or foreign law. To the extent that amounts are so withheld by Parent, Purchaser, the

Surviving Corporation or the Paying Agent, such amounts shall be treated for all purposes of this Agreement as having been paid to the holder of Warrants in
respect of which such deduction and withholding was made by Parent, Purchaser, the Surviving Corporation or the Paying Agent.

material respects with the applicable requirements of Section 4980B(f) of the Code or any similar state statute with respect to each Benefit Plan that is a group health plan within the meaning of Section 5000(b)(1) of the Code or such
state statute. Neither the Company nor any Company Subsidiary has any material obligations for retiree health or life insurance benefits under any Benefit Plan (other than for continuation coverage under Section 4980B(f) of the Code).

(h) Except as may be required by applicable law, or as contemplated under this Agreement, neither the Company nor any Company Subsidiary
has any plan or commitment to create any additional Benefit Plans or Foreign Plans, or to amend or modify any existing Benefit Plan or Foreign Plan in such a manner as to materially increase the cost of such Benefit Plan or Foreign Plan to the
Company or any Company Subsidiary.

(i) Section 3.11(i) of the Company Disclosure Schedule discloses: (i) each material payment
(including any bonus, severance, unemployment compensation, deferred compensation, forgiveness of indebtedness or golden parachute payment) becoming due to any current or former employee under any Benefit Plan or Foreign Plan because of this
Agreement (or the consummation of the Transactions); (ii) any increase in any material respect of any benefit otherwise payable under any Benefit Plan or Foreign Plan; (iii) any acceleration in any material respect of the time of payment
or vesting of any such benefits under any Benefit Plan or Foreign Plan; or (iv) any material obligation to fund any trust or other arrangement with respect to compensation or benefits under a Benefit Plan or Foreign Plan in each case caused or
triggered by the execution and delivery of this Agreement or the consummation of the Offer or the Merger or the other Transactions contemplated hereby. No payment or benefit which has been, will or may be made by the Company or any Company
Subsidiary with respect to any current or former employee located in the United States in connection with the execution and delivery of this Agreement or the consummation of the Transactions contemplated hereby would fail to be deductible under
Section 162(m) of the Code. Neither this Agreement (or the consummation of the Transactions contemplated hereby) nor any other agreement, plan, arrangement or other contract between the Company or any Company Subsidiary and an employee or other
service provider that, considered individually or considered collectively with any other such agreements, plans, arrangements or other contracts,

could reasonably be expected to, give rise directly or indirectly to the payment of any amount that would be characterized as an excess parachute
payment within the meaning of Section 280G(b)(1) of the Code.

(k) Neither the Company nor any Subsidiary has entered into any contract, agreement, arrangement or understanding with any officer or director of the
Company or any Company Subsidiary in connection with or in contemplation of the Transactions, except as contemplated by this Agreement or the Transactions.

(l) To the knowledge of the Company, no payment pursuant to any Benefit Plans or other arrangement between the Company or a Company Subsidiary and any service provider (as such term is defined in
Section 409A of the Code and the United States Treasury Regulations and IRS guidance thereunder), including, without limitation, the grant, vesting or exercise of any stock option or the grant or vesting of an RSU, would subject any Person to a
tax pursuant to Section 409A of the Code, whether pursuant to the consummation of the Offer or the Merger, any other transactions contemplated by this Agreement or otherwise.

(m) All Company Options have been appropriately authorized by the Companys Board of Directors or an appropriate committee thereof, including
approval of the option exercise price or the methodology for determining the option exercise price and the substantive option terms. All Company Options granted to employees in the United States that are potentially subject to Code Section 409A
have a per share exercise price which reflects the fair market value of the Companys common stock as determined in good faith compliance with Section 409A of the Code on the date that the option was granted (within the meaning of United
States Treasury Regulation §1.421-1(c)). To the knowledge of the Company, no Company Options have been retroactively granted, or the exercise price of any Company Option determined retroactively. The Company Board of Directors, at a meeting
duly called and held, has determined that each of the members of the Compensation Committee of the Company Board of Directors (the Compensation Committee) are, and the Company represents and warrants that each of the members of
the Compensation Committee are and at the Expiration Date will be, independent directors as defined in Rule 4200(a)(15) of the Nasdaq Marketplace Rules and eligible to serve on the Compensation Committee under the Exchange Act and all

Nasdaq Marketplace Rules. On or prior to the date hereof, the Compensation Committee, at a meeting duly called and held, approved each Company Compensation
Arrangement as an employment compensation, severance or other employee benefit arrangement within the meaning of Rule 14d-10(d)(1) under the Exchange Act (an Employment Compensation Arrangement), and has taken all
other action necessary to satisfy the requirements of the non-exclusive safe-harbor with respect to such Company Compensation Arrangements in accordance to Rule 14d-10(d)(2) under the Exchange Act.

owing by any of the Company and each Company Subsidiary on or before the date hereof (whether or not shown on any Tax Returns) have been paid, or both are being contested in good faith and have been reserved for in accordance with GAAP on the
Financial Statements. None of the Company or any Company Subsidiary currently is the beneficiary of any extension of time within which to file any material Tax Return. No claim has ever been made by a Tax authority in a jurisdiction where any of the
Company or any Company Subsidiary does not file Tax Returns that it is or may be subject to taxation by that jurisdiction.

(b) The unpaid
Taxes of the Company and each Company Subsidiary did not, as of the dates of the Financial Statements, exceed the reserve for Tax liability set forth on the face of the balance sheets contained in such Financial Statements. Since the date of the
most recent Financial Statements, neither the Company nor any of the Company Subsidiaries have incurred any liability for Taxes outside the ordinary course of business or otherwise inconsistent with past practice.

(c) No deficiencies for material Taxes with respect to any of the Company and the Company Subsidiaries have been claimed or proposed in writing or
assessed by any Tax authority. There are no pending or, to the Companys knowledge, threatened audits, assessments or other actions for or relating to any material liability in respect of Taxes of any of the Company or any of the Company
Subsidiaries, and there are no matters under discussion with any Tax authority, or known to the Company or any of the Company Subsidiaries, with respect to Taxes that are likely to result in an additional material liability for Taxes with respect to
any of the Company or any Company Subsidiaries. The Company has delivered or made available to Parent complete and accurate copies of federal, state and local income Tax Returns and other material Tax Returns of each of the Company and the Company
Subsidiaries and their predecessors for the years ended December 31, 2003 through 2005, and complete and accurate copies of all examination reports and statements of deficiencies assessed against or agreed to by any of the Company and the
Company Subsidiaries or any predecessors since January 1, 2003, with respect to Taxes of any type. Neither the Company nor any of the Company Subsidiaries nor any predecessor has waived any statute of limitations in respect of material Taxes or
agreed to any extension of time with respect to a material Tax assessment or deficiency, nor has any request been made in writing for any such extension or waiver.

member of an affiliated group filing a consolidated federal income Tax Return (other than a group the common parent of which is the Company).

(h) There are no Tax sharing agreements or similar arrangements (including indemnity arrangements) with respect to or involving any of the Company and the Company Subsidiaries (except for the allocation of Taxes set forth in leases,
contracts and commercial agreements entered into in the ordinary course of business), and, after the Closing Date, none of the Company nor any of the Company Subsidiaries shall be bound by any such Tax sharing agreements or similar arrangements or
have any liability thereunder for amounts due in respect of periods prior to the Closing Date.

(i) Neither the Company nor any of the
Company Subsidiaries has constituted a distributing corporation or a controlled corporation (within the meaning of Section 355(a)(1)(A) of the Code) in a distribution of stock to which Section 355 of the Code (or so
much of Section 356 of the Code as relates to Section 355 of the Code) applies.

(j) Neither the Company nor any of the Company
Subsidiaries (i) has agreed, or is required, to make any adjustment under Section 481(a) of the Code for any period after the Closing Date by reason of a change in accounting method or otherwise; or (ii) is a shareholder of a

Section 3.14 Title to Properties; Encumbrances. The Company and each of the Company Subsidiaries has good, valid and marketable title to,
or, in the case of leased properties and assets, valid leasehold interests in, all of its tangible properties and assets except where the failure to have such good, valid and marketable title has not had and would not reasonably be expected to have,

owned by another Person has been pursuant to the terms of a written agreement with such Person permitting such use or was otherwise lawful, except to the extent that any such use or disclosure that was not done in accordance with such a written
agreement does not and will not, individually or in the aggregate, give rise to a Company Material Adverse Effect. The Company and its Subsidiaries have executed confidentiality agreements with all employees and contractors to whom the Company or
its Subsidiaries have granted access to Trade Secrets, which agreements prohibit such employees and contractors from disclosing such Trade Secrets to third parties or using such Trade Secrets for any purpose other than for the benefit of the Company

Property Right of another Person is pending or, to the knowledge of the Company, has been threatened against Company or its Subsidiaries. Neither the Company nor any of its Subsidiaries has received any notice or other communication relating to any
actual, alleged, or suspected infringement, misappropriation, or violation of any Intellectual Property Right of another Person by Company or any Subsidiary. The Company and its Subsidiaries are not subject to any Order of any Governmental Entity
that restricts or impairs the use of any Company IP.

Rights, (ii) any right, including any right of termination, amendment, modification, cancellation or acceleration under any Company IP Agreement, (iii) the loss of or the imposition of any Lien on any Owned Company IP, (iv) the

Subsidiaries collection and dissemination of personal information in connection with their business has been conducted in accordance with applicable privacy policies published or otherwise adopted by the Company and its Subsidiary and any

affected in any manner adverse to any party. Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the parties hereto shall negotiate in good faith to modify this Agreement so as to effect the
original intent of the parties as closely as possible in an acceptable manner to the end that the Offer and the Merger are fulfilled to the extent possible.

relating thereto, and each of the parties hereby irrevocably and unconditionally (i) agrees not to commence any such action or proceeding except in such courts, (ii) agrees that any claim in respect of any such action or proceeding may be
heard and determined in such Delaware Court of Chancery court or, if no such state court has proper jurisdiction, the in such Federal court, (iii) waives, to the fullest extent it may legally and effectively do so, any objection which it may
now or hereafter have to the laying of venue of any such action or proceeding in any such Delaware Court of Chancery or Federal court, and (iv) waives, to the fullest extent permitted by law, the defense of an inconvenient forum to the
maintenance of such action or proceeding in any such Delaware Court of Chancery or Federal court. Each of the parties hereto agrees that a final judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions
by suit on the judgment or in any other manner provided by law. Each party to this Agreement irrevocably consents to service of process in the manner provided for notices in Section 9.4. Nothing in this Agreement will affect the right of any
party to this Agreement to serve process in any other manner permitted by law. Each party hereto agrees not to commence any legal proceedings relating to or arising out of this Agreement or the Transactions in any jurisdiction or courts other than
as provided herein.

Section 9.12 Waiver of Jury Trial. EACH PARTY IS HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY RIGHT
IT MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT AND ANY OF THE AGREEMENTS DELIVERED IN CONNECTION HEREWITH OR THE OFFER AND MERGER CONTEMPLATED HEREBY OR THEREBY. EACH

by operation of law or otherwise) without the prior written consent of the other parties, except that Purchaser may assign, in its sole discretion and without the consent of any other party, any or all of its rights, interests and obligations
hereunder to (i) Parent, (ii) to Parent and one or more direct or indirect wholly-owned Subsidiaries of Parent or (iii) to one or more direct or indirect wholly-owned Subsidiaries of Parent (each, an Assignee).

be binding upon, inure to the benefit of and be enforceable by the parties and their respective successors and assigns. Notwithstanding anything to the
contrary contained herein, Parent, Purchaser and their affiliates shall have the right to collaterally assign in whole or in part this Agreement and any ancillary agreements or documents related to the Transactions and any of their respective rights
thereunder as security to one or more lenders or purchasers of debt securities who, in each case, are being granted a collateral interest in this Agreement or any ancillary agreements or documents related to the Transactions.

Section 9.14 Enforcement; Remedies. The parties hereto agree that irreparable damage would occur in the event that any of the provisions of
this Agreement were not performed in accordance with their specific terms. It is accordingly agreed that the parties hereto shall be entitled seek an injunction or injunctions to prevent breaches of this Agreement and to specifically enforce the
terms hereof, this being in addition to any other remedy to which they are entitled at law or in equity. Except as otherwise provided herein, any and all remedies herein expressly conferred upon a party will be deemed cumulative with and not
exclusive of any other remedy conferred hereby, or by law or equity upon such party, and the exercise by a party of any one remedy will not preclude the exercise of any other remedy.

Notwithstanding any other provisions of the Offer, but subject to the terms and conditions set forth in the Merger Agreement, and in addition to (and not in limitation of) Purchasers rights and obligations to

Expiration Date:

(a) there shall be threatened in writing or pending any suit, action or proceeding by any Governmental Entity of competent

or consummation of the Offer or the Merger, (ii) seeking to impose material limitations on the ability of Purchaser (or Parent on Purchasers behalf), or render Purchaser (or Parent on Purchasers behalf) unable, to accept for
payment, pay for or purchase any or all of the Shares pursuant to the Offer or the Merger, or seeking to require divestiture thereof or any material assets of the Company or any Company Subsidiary, (iii) seeking to prohibit or impose any
material limitations on the ownership or operation by Parent (or any of its Subsidiaries) of all or any portion of businesses or assets of Parent, the Company or any of their respective Subsidiaries as a result of or in connection with the

I-i



---

any other action shall be taken by any Governmental Entity, other than the application to the Offer or the Merger of applicable waiting periods under HSR Act
or similar waiting periods with respect to the Required Governmental Approvals, that (x) is, in the reasonable judgment of Parent and Purchaser, likely, individually or in the aggregate, to result, directly or indirectly, in any of the
consequences referred to in clauses (i) through (v) of paragraph (a) above, or (y) has the effect of making such transactions illegal or which has the effect of prohibiting or otherwise preventing the consummation of any of the
transactions contemplated by the Merger Agreement;

(c)(i) any of the representations and warranties of the Company contained in Sections
3.2, 3.3, 3.4 or 3.5(b) shall not be true and correct in all material respects, each as of the date hereof and as of the expiration date of the Offer with the same force and effect as if made on and as of such date, except for representations and
warranties that relate to a specific date or time (which need only be true and correct in all material respects as of such date or time), or (ii) except as has not had and would not reasonably be expected to have, individually or in the
aggregate with all other failures to be true or correct, a Company Material Adverse Effect, the representations and warranties of the Company contained in this Agreement, other than representations and warranties referenced in clause (i) of
this paragraph (c), shall not be true and correct in all respects (without giving effect to any references to any Company Material Adverse Effect or materiality qualifications and other qualifications based upon the concept of materiality or similar
phrases contained therein and without giving effect to any modifications or updates to the Company Disclosure Schedule) as of the date of the Merger Agreement and as of the expiration date of the Offer with the same force and effect as if made on
and as of such date, except for representations and warranties that relate to a specific date or time (which need only be true and correct (without giving effect to any references to any Company Material Adverse Effect or materiality qualifications
and other qualifications based upon the concept of materiality or similar phrases contained therein and without giving effect to any modifications or updates to the Company Disclosure Schedule) as of such date or time);

(d) since the date of the Merger Agreement, any fact(s), change(s), event(s), development(s) or circumstance(s) have occurred, arisen or come into
existence or become known to the Company, Parent or Purchaser, which is continuing and which has had or would reasonably be expected to have, individually or in the aggregate with all other such fact(s), change(s), event(s), development(s) or
circumstance(s), a Company Material Adverse Effect;

(e) the Company shall have breached or failed, in any material respect, to perform or
to comply with any agreement or covenant to be performed or complied with by it under the Merger Agreement prior to the expiration of the Offer (or, in the case of Section 6.1 hereof, shall have intentionally breached or failed in any material
respect to perform or comply with such Section 6.1) and such breach or failure shall not have been cured;

(f) Purchaser shall have
failed to receive a certificate of the Company, executed by the Chief Executive Officer and the Chief Financial Officer of the Company, dated as of the scheduled Expiration Date, to the effect that the conditions set forth in paragraphs (c) and

I-ii



---

(g) the Merger Agreement shall have been terminated in accordance with its terms.

The foregoing conditions are for the sole benefit of Parent and Purchaser, may be asserted by Parent or Purchaser regardless of the circumstances giving
rise to such condition, and may be waived by Parent or Purchaser in whole or in part at any time and from time to time and in the sole discretion of Parent or Purchaser, subject in each case to the terms of the Merger Agreement. The foregoing
conditions shall be in addition to, and not a limitation of the rights of Parent and Purchaser to extend, terminate and/or modify the Offer pursuant to the terms and conditions of the Merger Agreement. Any reference in this Annex I or in the Merger
Agreement to a condition or requirement being satisfied shall be deemed met if such condition or requirements is so waived. The failure by Parent or Purchaser at any time to exercise any of the foregoing rights shall not be deemed a waiver of any
such right and, each such right shall be deemed an ongoing right that may be asserted at any time and from time to time.

As used in this
Annex I, the term Required Governmental Approvals shall mean any applicable review process by CFIUS under the Exon-Florio Act (including, if applicable, any investigation commenced thereunder) and any other material approval or
consent of any Governmental Entity of competent jurisdiction reasonably deemed necessary, appropriate or desirable by Parent by the later of (i) ten business days after the date of the Merger Agreement, and (ii) five business days after
Parent has received all information from the Company which is reasonably necessary to enable Parent to determine which such approvals or consents may be necessary, appropriate or desirable under applicable law, as shall be evidenced by a list of
which will be delivered to the Company within such period. The other capitalized terms used in this Annex I shall have the meanings set forth in the Agreement to which it is annexed, except that the term Merger Agreement shall be
deemed to refer to the Agreement to which this Annex I is annexed.

Schedule 5.4

Promptly after the date of the Agreement, the Company will issue to and set aside with a disbursement agent (the Disbursement Agent) the maximum number of Shares that the Company would be required to issue
pursuant to the Reorganization Plan and the Bankruptcy Confirmation Order to the holders of such Unresolved Bankruptcy Claims/Interests were such Unresolved Bankruptcy Claims/Interests allowed in the respective maximum amounts claimed by such
holders (the Escrowed Shares). To the extent any Unresolved Bankruptcy Claims/Interests are allowed in a liquidated amount prior to the Effective Time, the Disbursement Agent shall promptly distribute the applicable portion of the
Escrowed Shares to the holders of such allowed Unresolved Bankruptcy Claims/Interests, and if all Unresolved Bankruptcy Claims/Interests have been resolved as of the Effective Time, then all Escrowed Shares not required to be distributed to any
holders of Unresolved Bankruptcy Claims/Interests shall be delivered by the Disbursement Agent to the Company and cancelled pursuant to Section 2.1(b) of the Agreement. If, as of the Effective Time, any Escrowed Shares remain undistributed, and
one or more Unresolved Bankruptcy Claims/Interests remain unresolved, then (i) that portion of the remaining Escrowed Shares that would be required to be issued pursuant to the Reorganization Plan and Bankruptcy Confirmation Order to the
holders of such Unresolved Bankruptcy Claims/Interests were such Unresolved Bankruptcy Claims/Interests allowed in the respective maximum amounts claimed by such holders shall be converted to the right to receive Merger Consideration pursuant to
Section 2.1(c) of the Agreement, and the applicable portion of such Merger Consideration shall be distributed to such holders as and when their Unresolved Bankruptcy Claims/Interests are allowed in a liquidated amount, and (ii) the
remaining portion of such Escrowed Shares shall be delivered by the Disbursement Agent to the Company and cancelled pursuant to Section 2.1(b) of the Agreement. Upon resolution and payment from the Merger Consideration of all Unresolved
Bankruptcy Claims/Interests that were unresolved as of the Effective Time, any remaining Merger Consideration shall be delivered by the Disbursement Agent to the Company and shall become unrestricted cash of the Company.
