     Securities"), the Company shall first offer to sell to each holder of
     Preferred Stock a portion of such Equity Securities to be issued equal to

     the same terms and conditions) that such other Persons are required to
     purchase. The purchase price for all stock and securities offered to such
     holders hereunder shall be payable in cash.

               (ii) In order to exercise its purchase rights hereunder, the

     holders of Preferred Stock have not elected to purchase during the 180 days
     following such expiration at a price not less and on other terms and
     conditions not more favorable to the purchasers thereof than that offered
     to such holders. Any stock or securities offered or sold by the Company

applicable law or governmental regulations or by order of a court of competent
jurisdiction, in which case, unless otherwise prohibited by applicable law,
prior to making such disclosure the Company shall give written notice to such
Purchaser describing in

                                       12

material respects with the requirements of the Securities Exchange Act, the
Securities Act and the published rules and regulations of the Securities and
Exchange Commission thereunder, each as applicable to all SEC Reports.

          4I. Confidentiality.

               (i) Each holder of Preferred Stock shall hold, and shall use its
     reasonable efforts to cause its Representatives to hold, in confidence,
     unless compelled to disclose by judicial or administrative process or by
     other requirements of law or national stock exchange, all confidential
     documents and information concerning the Company or any of its Subsidiaries
     furnished to the such holder of Preferred Stock, except to the extent that
     such information can be shown to have been (a) previously known on a
     non-confidential basis by the holder of Preferred Stock or such
     Representatives, (b) in the public domain through no fault of such holder
     of Preferred Stock or its Representatives (acting in their capacity as such
     or with respect to information received in their capacity as such) or (c)
     later acquired by such holder of Preferred Stock or its Representatives
     from sources other than the Company or any of its Subsidiaries not known by
     such holder of Preferred Stock or such Representatives, as applicable, to
     be bound by any confidentiality obligation; provided that a holder of
     Preferred Stock may disclose such information if required by applicable
     law, subject to compliance with Section 4I(ii); provided further that a
     holder of Preferred Stock may disclose such information to any of its
     Representatives in connection with the transactions contemplated by this
     Agreement or its ownership of the Preferred Stock and monitoring of its
     investment therein so long as such Persons are informed by the holder of
     Preferred Stock of the confidential nature of such information and are
     directed by such holder of Preferred Stock to treat such information
     confidentially; provided further that the holder of Preferred Stock may
     disclose such information in connection with a sale or transfer (or
     prospective sale or transfer) permitted by Section 5A of any Preferred
     Stock if such holder of Preferred Stock's transferee (or prospective
     transferee) agrees to be bound by the provisions of this section. Each
     holder of Preferred Stock shall be responsible for any failure of it or any
     of its Representatives to treat such information confidentially. Each
     holder of Preferred Stock agrees that it shall not and it shall cause each
     of its Representatives not to use any confidential documents or information
     for any purpose other than monitoring and evaluating its investment in the
     Company and in connection with the transactions contemplated by this
     Agreement.

               (ii) In the event any of the holders of Preferred Stock or anyone
     to whom any of the holders of Preferred Stock transmit confidential
     information is requested or required (by oral questions, interrogatories,
     requests for information or documents, subpoenas, civil investigative
     demand or similar process) to disclose any

                                       13

<PAGE>

     such information, such holder of Preferred Stock shall provide the Company
     with prompt notice so that the Company may seek a protective order or other
     appropriate remedy and/or waive such holder's compliance with the
     provisions of this section. In the event that such protective order or
     other remedy is not obtained sufficiently promptly so as not to adversely
     affect such holder of Preferred Stock or those of its officers, directors,
     employees, accountants, counsel, consultants, advisors and agents as to
     whom the information has been requested or required, or the Company waives
     such holder's compliance with the provisions of this Agreement, such holder
     will furnish only that portion of such information that such holder is
     advised by counsel is legally required and shall, at the Company's expense
     and direction, exercise its reasonable efforts to obtain reliable assurance
     that confidential treatment will be accorded such information.

          OR OTHERWISE DISTRIBUTED EXCEPT IN CONJUNCTION WITH AN EFFECTIVE
          REGISTRATION STATEMENT FOR THE SECURITIES UNDER THE SECURITIES ACT, OR
          IN COMPLIANCE WITH RULE 144 OR PURSUANT TO ANOTHER EXEMPTION. THE
          SECURITIES ARE ALSO SUBJECT TO PROVISIONS OF A REGISTRATION RIGHTS
          AGREEMENT."

          (ii) "THE TRANSFER OF THE SECURITIES REPRESENTED BY THIS CERTIFICATE
          IS SUBJECT TO

                                       14

<PAGE>

          THE CONDITIONS SPECIFIED IN THE PREFERRED STOCK PURCHASE AGREEMENT,
          DATED AS OF APRIL 24, 2003 (AS THE SAME MAY BE AMENDED FROM TIME TO
          TIME), BETWEEN THE ISSUER (THE "COMPANY") AND CERTAIN OTHER PERSONS,
          AND THE COMPANY RESERVES THE RIGHT TO REFUSE THE TRANSFER OF SUCH
          SECURITIES UNTIL SUCH CONDITIONS HAVE BEEN FULFILLED WITH RESPECT TO
          SUCH TRANSFER. A COPY OF SUCH CONDITIONS SHALL BE FURNISHED BY THE
          COMPANY TO THE HOLDER HEREOF UPON WRITTEN REQUEST AND WITHOUT CHARGE."

               In addition, the certificates representing Preferred Stock shall
bear the following legend:

          "The Company will furnish the holder of this certificate information
          concerning the designations, relative rights, preferences and
          limitations applicable to each class of stock or series hereof,
          including the liquidation and dividend preferences and voting and
          conversion rights of the preferred stock, on request in writing and
          without charge."

               Whenever any particular securities cease to be Restricted
Securities, the holder thereof shall be entitled to receive from the Company,
without expense, new securities of the like tenor not bearing a Securities Act
legend of the character set forth in Section 5C(i).

          5D. Legend Removal. If any Restricted Securities become eligible for
sale pursuant to Rule 144(k), the Company shall, upon the request of the holder
of such Restricted Securities, remove the legend set forth in Section 5C(i) from
the certificates for such Restricted Securities. In addition, if in connection
with any transfer the holder of the Restricted Securities delivers to the
Company an opinion of Kirkland & Ellis or such other counsel which (to the
Company's reasonable satisfaction) is knowledgeable in securities law matters to
the effect that no subsequent transfer of such Restricted Securities shall
require registration under the Securities Act, then the Company promptly upon
such contemplated shall transfer deliver new certificates for such Restricted
Securities which do not bear the Securities Act legend set forth in Section
5C(i). In addition, the Company shall, upon the request of the holder of such
Restricted Securities, remove the legend set forth in Section 5C(ii) from the
certificates for such Restricted Securities upon a conversion of Restricted
Securities constituting Preferred Stock into Common Stock.

          5E. Right of First Offer. At least 15 business days prior to
transferring any shares of Preferred Stock pursuant to Section 5A(iv), the
transferring shareholder (the "Transferring Shareholder") shall deliver a
written notice (a "Sale Notice") to the Company. The Sale Notice shall disclose
in reasonable detail the proposed number of shares of Preferred Stock to be
transferred. The Company may offer to purchase all (but not less than all) of
the shares of Preferred Stock specified in the Sale Notice by delivering written
notice of such offer (a

                                       15

<PAGE>

"Company Offer") to the Transferring Shareholder, as soon as practicable but in
any event within 15 days after the delivery of the Sale Notice (the "Election
Period"), disclosing in reasonable detail the proposed terms and conditions
(including the offer price) of the Company's offer in a binding commitment (if
accepted by the Transferring Shareholder within 60 days) to purchase the
Transferring Shareholder's Preferred Stock specified in the Sale Notice. If
within the Election Period the Company has offered to purchase the shares of
Preferred Stock from the Transferring Shareholder in a Company Offer, the
Transferring Shareholder may, within 60 days after receipt of the Company Offer
(the "Offer Period"), either accept or decline the Company Offer. If the
Transferring Shareholder accepts the Company's Offer within such 60 day period,
then the Transferring Shareholder and the Company shall be bound, and the
transfer of such shares shall be consummated as soon as practical after the
delivery of the Transferring Shareholder's acceptance of the Company Offer, but
in any event within 30 days after the acceptance of the Company Offer. If the
Transferring Shareholder declines the Company Offer, then it may transfer such
shares of Preferred Stock (specified in the Sale Notice) at a price no less than
the price per share specified in the Company Offer within 120 days after the
expiration of the Election Period. If the Company has not made a Company Offer
(which must be with respect to all of the shares of Preferred Stock in the Sale
Notice), then the Transferring Shareholder may, within 180 days after the
expiration of the Election Period, transfer such shares of Preferred Stock
specified in the Sale Notice to one or more third parties. The Transferring
Shareholder shall deliver a new Sale Notice under this Section 5E with respect
to any shares of Preferred Stock not transferred within such 180-day period
after the expiration of the Election Period prior to any subsequent transfer.
The purchase price specified in any Company Offer shall be payable solely in
cash at the closing of the transaction. If the Company has failed to consummate
a Company Offer that one or more Transferring Shareholder(s) accepted, then this
Section 5E shall cease to apply with respect to such Transferring Shareholder(s)
and shall no longer require such Transferring Shareholder(s) to deliver a Sale
Notice to the Company prior to transferring any Preferred Stock.

          Section 6. Representations and Warranties of the Company. As a
material inducement to the Purchasers to enter into this Agreement and purchase
the Preferred Stock hereunder, the Company hereby represents and warrants to
each Purchaser that:

          6A. Organization; Ownership; Power; Qualification of the Company. The
Company is a corporation duly organized, validly existing and in good standing
under the laws of the State of Delaware and is duly qualified as a foreign
corporation to transact business and is in good standing in each jurisdiction in
which such qualification is required, whether by reason of the ownership or
leasing of property or the conduct of business, except where the failure to be
so qualified as a foreign corporation or be in good standing would not have a
Material Adverse Effect. The Company possesses all requisite corporate power and
authority and all material licenses, permits and authorizations necessary to
own, lease and operate its properties and to conduct its business as now
conducted and presently proposed to be conducted except such as would not
reasonably be expected to have a Material Adverse Effect. The Company possesses
all requisite corporate power and authority and all material licenses, permits
and authorizations necessary to enter into this Agreement and the agreements

                                       16

          6B. Subsidiaries. Each of the Company's Subsidiaries is duly
organized, validly existing as a corporation, general partnership, limited
partnership, limited liability company, closed joint stock company or similar
entity, and in good standing under the laws of the jurisdiction of its
organization and is duly qualified as a foreign corporation or other entity to
transact business and is in good standing in each jurisdiction in which such
qualification is required, whether by reason of the ownership or leasing of
property or the conduct of business, except where the failure to be so qualified
as a foreign corporation or be in good standing would not have a Material
Adverse Effect. Each Subsidiary possesses all requisite organizational power and
authority and all material licenses, permits and authorizations necessary to
own, lease and operate its properties and to conduct its business as now
conducted and presently proposed to be conducted except such as would not
reasonably be expected to have a Material Adverse Effect. All of the issued and
outstanding shares of capital stock or other ownership interests of each such
Subsidiary are duly authorized and are validly issued, fully paid and
non-assessable (to the extent applicable) and owned by the Company, directly or
through Subsidiaries except such as would not reasonably be expected to have a
Material Adverse Effect.

          6C. Capital Stock and Related Matters.

               (i) As of March 31, 2006, the authorized capital stock of the
     Company consists of (a) 2,000,000 shares of preferred stock, of which no
     shares are designated, and (b) 50,000,000 shares of Common Stock, of which
     30,222,983 shares are issued and outstanding and 6,254,418 shares are
     reserved under the Permitted Stock Plans (of which options for 4,504,463
     shares of Common Stock have been granted). As of the Closing and
     immediately thereafter, the authorized capital stock of the Company shall
     consist of (a) 2,000,000 shares of preferred stock, of which 50,000 shares
     shall be designated as Series B Preferred Stock (all of which shall be
     issued and outstanding) and of which no other shares shall be designated,
     and (b) 50,000,000 shares of Common Stock, of which 30,222,983 shares (plus
     any shares issued upon the exercise of options between the date of this
     Agreement and the Closing Date) shall be issued and outstanding, 6,254,418
     shares shall be reserved under the Permitted Stock Plans and 4,255,320
     shares shall be reserved for issuance upon conversion of the Preferred
     Stock. Except as set forth above or as disclosed in the Company SEC
     Reports, neither the Company nor any Subsidiary has outstanding any stock
     or securities convertible into or exchangeable for any shares of its
     capital stock or containing any profit participation features, nor does it
     have outstanding any rights or options to subscribe for or to purchase its
     capital stock or any stock or securities convertible into or exchangeable
     for its capital stock or any stock appreciation rights or phantom stock
     plans, except for the Preferred Stock. Neither the Company nor any
     Subsidiary is subject to any obligation (contingent or otherwise) to
     repurchase or otherwise acquire or retire any shares of its capital stock
     or any warrants, options or other rights to acquire its capital stock
     except pursuant to the Certificate of Designation. All of the outstanding
     shares of the Company's capital stock are validly issued, fully paid and
     nonassessable.

               (ii) There are no statutory or, to the Company's Knowledge,
     contractual shareholders' preemptive rights or rights of refusal with
     respect to the issuance or sale of the Preferred Stock hereunder or the
     issuance of Common Stock upon conversion of the Preferred Stock. The
     Company has complied with all applicable

                                       17

<PAGE>

     federal or state securities laws in connection with the offer, sale and
     issuance of the Preferred Stock hereunder, and such offer, issuance and
     sale do not require registration under the Securities Act or any applicable
     state securities laws. Except such as would not reasonably be expected to
     have a Material Adverse Effect, the Company has complied with all
     applicable federal or state securities laws in connection with the offer,
     sale or issuance of any of its capital stock. Except as disclosed in the
     Company SEC Reports, there are no agreements between the Company and any of
     its shareholders or, to the Company's Knowledge, among any of the Company's
     shareholders with respect to the voting or transfer of the Company's
     capital stock or with respect to any other aspect of the Company's affairs.

          6D. Authorization; No Breach. The execution, delivery and performance
of each of the Transaction Documents, the filing of the Certificate of
Designation and the offering, sale and issuance of the Preferred Stock to the
Purchasers have been duly authorized by all necessary corporate action on the
part of the Company. Each of the Transaction Documents constitutes a valid and
binding obligation of the Company, enforceable in accordance with its terms. The
Articles of Incorporation have been duly adopted and are in full force and
effect and enforceable in accordance with their terms and the Certificate of
Designation will have been duly adopted as of the Closing and will be in full
force and effect and enforceable in accordance with its terms. The offering,
sale and issuance of the Preferred Stock hereunder, the issuance of the Common
Stock upon conversion of the Preferred Stock, the filing of the Certificate of
Designation, changes or circumstances that may occur as a result of the terms of
the Preferred Stock, whether pursuant to Section 5C of the Certificate of
Designation or otherwise (but not including, for the avoidance of doubt, any
purchase or other acquisition by any such holder of additional securities of the
Company other than acquisitions that result from the terms of the Preferred
Stock)), the execution and delivery by the Company of each of the Transaction
Documents and the fulfillment of and compliance with the other respective terms
hereof and thereof by the Company, do not and will not (i) conflict with or
result in a breach of any of the terms, conditions or provisions of, (ii)
constitute a default under, (iii) result in the creation of any lien, security
interest, charge or encumbrance upon the Company's or any Subsidiary's capital
stock or assets pursuant to, (iv) give any third party the right to modify,
terminate or accelerate any obligation under or claim any change of control or
similar payments pursuant to, (v) result in a violation of, or (vi) require any
authorization, consent, approval, exemption or other action by or notice or
declaration to, or filing with, any court or administrative or governmental body
or agency pursuant to, the charter (including the Certificate of Designation) or
the Bylaws or the bylaws of any Subsidiary, or any law or statute or any rule,
regulation, order, writ, injunction or decree of any court or administrative
government body or agency to which the Company or any Subsidiary is subject, or
any material agreement, instrument, order, judgment or decree to which the
Company or any Subsidiary is subject. The Company is not a party to or bound by
any written or oral agreement or understanding with respect to any Alternative
Transaction, and has terminated all discussions with third parties regarding any
Alternative Transactions.

          6E. SEC Reports and Financial Statements.

               (i) The Company has filed with the SEC on a timely basis all
     reports, schedules, forms, statements and other documents required to be
     filed, as such documents may have been amended or supplemented with the SEC
     since the time of filing (the

                                       18

<PAGE>

     "Company SEC Documents"). No Subsidiary of the Company is required to file
     with the SEC any report, schedule, form, statement or other document. Each
     of the Company SEC Documents, (i) as of the filing date of such report,
     complied with the requirements of the Securities Act of 1933, as amended,
     and the rules and regulations promulgated thereunder (the "Securities Act")
     and the Exchange Act, as the case may be, and, to the extent then
     applicable, the Sarbanes-Oxley Act of 2002 and the rules and regulations
     promulgated thereunder (the "Sarbanes-Oxley Act"), and (ii) as of its
     filing date (or, if amended or superseded by a subsequent filing prior to
     the date hereof, on the date of such filing) did not contain any untrue
     statement of a material fact or omit to state a material fact required to
     be stated therein or necessary in order to make the statements made
     therein, in the light of the circumstances under which they were made, not
     misleading. As used in this Section 6E, the term "file" shall be broadly
     construed to include any manner in which a document or information is
     furnished, transmitted or otherwise made available to the SEC.

               (ii) The certifications and statements required by Rules 13a-14
     and 15d-14 under the Exchange Act and Sections 302 and 906 of the
     Sarbanes-Oxley Act with respect to the applicable Company SEC Documents
     (collectively, the "Certifications"), were true and correct as of the date
     of filing thereof. Nothing has come to the attention of the principal
     executive officer or principal financial officer of the Company that would
     preclude each of them from being able to make the Certifications in the
     Company's next quarterly report on Form 10-Q when due.

               (iii) The Company maintains disclosure controls and procedures
     required by Rule 13a-15 or 15d-15 under the Exchange Act. Such disclosure
     controls and procedures are effective to ensure that all material
     information concerning the Company is made known on a timely basis to the
     individuals responsible for the preparation of the Company's filings with
     the SEC and other public disclosure documents. The Company has disclosed,
     based on its most recent evaluation prior to the date of this Agreement, to
     the Company's auditors and the Audit Committee of the Board of Directors of
     the Company (A) any control deficiencies in the design or operation of
     internal controls that could adversely affect in any material respect the
     Company's ability to record, process, summarize and report financial data
     and has identified for the Company's auditors any material weaknesses in
     internal controls and (B) any fraud, whether or not material, that involves
     management or other employees of the Company or its Subsidiaries. The
     Company has delivered or made available to the Majority Purchasers a
     summary of any such disclosure made by management to the Company's auditors
     or the Audit Committee of the Company's Board of Directors. No significant
     deficiency or material weakness was identified in management's assessment
     of internal controls as of March 16, 2006 (nor has any such deficiency or
     weakness since been identified). Neither the Company nor any of its
     Subsidiaries nor, to the Knowledge of the Company, any director, officer,
     employee, auditor, accountant or representative of the Company or any of
     its Subsidiaries has received or otherwise had or obtained knowledge of any
     complaint, allegation or claim, whether written or oral, alleging improper
     accounting or auditing practices, procedures, methodologies or methods or
     internal accounting control procedures of the Company or any of its
     Subsidiaries, including any complaint, allegation or claim that the Company
     or any of its Subsidiaries has engaged in

                                       19

<PAGE>

     questionable accounting or auditing practices. No attorney representing the
     Company or any of its Subsidiaries, whether or not employed by the Company
     or any of its Subsidiaries, has reported evidence of a violation of
     securities Laws, breach of fiduciary duty or similar violation by the
     Company or any of its officers, directors, employees or agents to the Board
     of Directors of the Company or any committee thereof or to any director or
     officer of the Company. Since March 16, 2006, neither the chief executive
     officer nor the chief financial officer of the Company has become aware of
     any fact or circumstance that is reasonably likely to result in a
     substantial change to the Company's internal controls over financial
     reporting.

               (iv) The Company is, and since enactment of the Sarbanes-Oxley
     Act has been, in compliance with the applicable provisions of the
     Sarbanes-Oxley Act and with the applicable listing and other rules and
     regulations of The Nasdaq National Market, and has not received any notice
     from The Nasdaq National Market asserting any non-compliance with such
     rules and regulations. Except as permitted by the Exchange Act, including
     Sections 13(k)(2) and (3), since the enactment of the Sarbanes-Oxley Act,
     neither the Company nor any of its affiliates has made, arranged, or
     modified (in any material way) personal loans to any executive officer or
     director of the Company. The audit committee of the Board of Directors of
     the Company includes an Audit Committee Financial Expert, as defined by
     Item 401(h)(2) of Regulation S-K.

               (v) The Company has adopted a code of ethics, as defined by Item
     406(b) of Regulation S-K, for senior financial officers, applicable to its
     principal financial officer, comptroller or principal accounting officer,
     or persons performing similar functions. The Company has promptly
     disclosed, by filing a Form 8-K, any change in or waiver of the Company's
     code of ethics, as required by Section 406(b) of Sarbanes-Oxley Act. To the
     Knowledge of the Company, there have been no violations of provisions of
     the Company's code of ethics.

               (vi) The financial statements of the Company for the fiscal year
     ended December 31, 2005 (the "Company Financial Statements"), and all other
     financial statements of the Company included in the Company SEC Documents,
     including in each case the notes thereto (collectively with the Company
     Financial Statements, the "SEC Financial Statements") complied, as of their
     respective dates of filing with the SEC, or with respect to unaudited
     financial statements, as of the date of this Agreement, in all material
     respects with applicable accounting requirements and the published rules
     and regulations of the SEC with respect thereto, were prepared in
     accordance with the United States generally accepted accounting principles
     ("GAAP") applied on a consistent basis during the periods covered (except
     as may be indicated therein or in the notes thereto or, in the case of
     unaudited financial statements, as permitted by Form 10-Q of the SEC) and
     fairly present in all material respects the consolidated financial position
     of the Company and its Subsidiaries as of the dates thereof and the
     consolidated results of their operations and cash flows for the periods
     then ended (subject, in the case of unaudited statements, to normal
     recurring year-end audit adjustments and other adjustments described
     therein).

               (vii) Except as set forth in the Company Financial Statements and
     except as arising hereunder, the Company and its Subsidiaries have no
     material liabilities

                                       20

<PAGE>

     or obligations of any nature (whether absolute, accrued, asserted or
     unasserted, contingent or otherwise) that would be required to be reflected
     on or reserved against in any SEC Financial Statements that are not
     disclosed, reflected or reserved against in such SEC Financial Statements,
     except for such liabilities and obligations (A) that have been incurred
     since March 16, 2006 in the Ordinary Course of Business, and (B) that could
     not reasonably be expected to have a Material Adverse Effect on the
     Company.

               (viii) Neither the Company nor any of its Subsidiaries is a party
     to, or has any commitment to become a party to, any joint venture,
     partnership agreement or any similar contract (including any contract
     relating to any transaction, arrangement or relationship between or among
     the Company or any of its Subsidiaries, on the one hand, and any
     unconsolidated Affiliate, including any structured finance, special purpose
     or limited purpose entity or Person, on the other hand) where the purpose
     or intended effect of such arrangement is to avoid disclosure of any
     material transaction involving the Company or any of its Subsidiaries in
     the Company's financial statements.

          6F. No Material Adverse Effect. To the Company's Knowledge, since
December 31, 2005, there has occurred no event, circumstance or condition which
has had or which could reasonably be expected to have a Material Adverse Effect.

          6G. Absence of Certain Developments.

               (i) Except as expressly contemplated by this Agreement, the
     Merger Agreement and the transactions contemplated hereunder or thereunder
     or as disclosed in the SEC Reports, since December 31, 2005, neither the
     Company nor any of its Subsidiaries has:

                    (a) issued any notes, bonds or other debt securities or any
     capital stock or other equity securities or any securities convertible,
     exchangeable or exercisable into any capital stock or other equity
     securities except those issued pursuant to the Permitted Stock Plans;

                    (b) borrowed any amount (except for intercompany loans) or
     incurred or become subject to any material liabilities, except current
     liabilities incurred in the ordinary course of business and material
     liabilities under contracts entered into in the ordinary course of
     business;

                    (c) discharged or satisfied any material Lien or paid any
     material obligation or liability, other than current liabilities paid in
     the ordinary course of business;

                    (d) other than as has been publicly announced by the
     Company, declared or made any payment or distribution of cash or other
     property to its shareholders with respect to its capital stock or other
     equity securities or purchased or redeemed any shares of its capital stock
     or other equity securities (including, without limitation, any warrants,
     options or other rights to acquire its capital stock or other equity
     securities);

                                       21

<PAGE>

                    (e) except in the ordinary course of business, mortgaged or
     pledged any of its properties or assets or subjected them to any Lien,
     except Liens for current property taxes not yet due and payable;

                    (f) sold, assigned or transferred any of its tangible
     assets, except in the ordinary course of business, or canceled any material
     debts or claims;

                    (g) entered into any agreement to acquire the capital stock
     or other equity interests of any Person;

                    (h) suffered any extraordinary losses or waived any rights
     of material value, other than in the ordinary course of business or
     consistent with past practice; or

                    (i) agreed, whether orally or in writing, to do any of the
     foregoing.

               (ii) Neither the Company nor any Subsidiary has at any time made
     any bribes, kickback payments or other illegal payments.

          6H. Tax Matters.

          The Company and each Subsidiary have filed all Tax Returns which they
are required to file under applicable laws and regulations; all such Tax Returns
are complete and correct in all material respects and have been prepared in
compliance with all applicable laws and regulations in all material respects;
the Company and each Subsidiary have paid all Taxes due and owing by them
(whether or not such Taxes are required to be shown on a Tax Return) and have
withheld and paid over to the appropriate taxing authority all Taxes which they
are required to withhold from amounts paid or owing to any employee,
shareholder, creditor or other third party except for Taxes in dispute for which
appropriate reserves have been taken on the Company's financial statements and
except such as would not reasonably be expected to have a Material Adverse
Effect; the accrual for Taxes on the Latest Balance Sheet would be adequate to
pay all Tax liabilities of the Company and its Subsidiaries if their current tax
year were treated as ending on the date of the Latest Balance Sheet (excluding
any amount recorded which is attributable solely to timing differences between
book and Tax income); since the date of the Latest Balance Sheet, the Company
and its Subsidiaries have not incurred any liability for Taxes other than in the
ordinary course of business; and except as specifically disclosed to the
Majority Purchasers in writing on the date hereof, no foreign, federal, state or
local Tax audits or administrative or judicial proceedings are pending or being
conducted with respect to the Company or any Subsidiary, no information related
to Tax matters has been requested by any foreign, federal, state or local taxing
authority and no written notice indicating an intent to open an audit or other
review has been received by the Company or any Subsidiary from any foreign,
federal, state or local taxing authority. The charges, accruals and reserves on
the books of the Company and its Subsidiaries in respect of Taxes are, in the
reasonable judgment of the Company, adequate.

     equitable relief against the Indemnitee), settle or compromise or consent
     to the entry of any judgment with respect to any litigation, or any
     investigation or proceeding by any Governmental Entity, commenced or
     threatened, or any claim whatsoever in respect to which indemnification or
     contribution could be sought under this Section 8D (whether or not the

     settlement, compromise or consent (a) includes an unconditional release of
     each indemnified party from all liability arising out of such litigation

     to or an admission of fault, culpability or a failure to act by or on
     behalf of any Indemnitee.

          8E. Purchaser's Investment Representations. Each Purchaser hereby
represents and warrants for itself individually and ratably and not jointly and
severally, that:

               (i) Organization, Good Standing, Power, Authority, Etc. Such
     Purchaser is validly organized and existing and in good standing under the
     laws of its jurisdiction of organization and has full power and authority
     to execute and deliver each of the Transaction Documents to which such
     Purchaser is a party, and to perform its obligations hereunder or
     thereunder. Such Purchaser has taken all necessary corporate or other
     organizational action in order to authorize the execution and delivery of
     each of the Transaction Documents to which such Purchaser is a party and
     the consummation of the transactions contemplated hereby or thereby, and
     each such agreement is a valid and binding obligation of such Purchaser,
     enforceable in accordance with its terms, except as such enforceability may
     be limited by bankruptcy, insolvency, reorganization, similar laws
     affecting creditors' rights generally or general principles of equity.

               (ii) No Conflicts; No Consents. Neither the execution nor
     delivery of any of the Transaction Documents to which such Purchaser is a
     party nor the consummation by such Purchaser of the purchase of the
     Preferred Stock contemplated hereby will conflict with, or result in any
     violation of, or constitute any default under, any provision of such
     Purchaser's organizational documents. Such Purchaser is not required to
     submit any notice, report or other filing with any governmental authority
     in connection

                                       40

<PAGE>

     with the execution or delivery by it of this Agreement or the consummation
     of the transactions contemplated hereby. No consent, approval or
     authorization of any governmental or regulatory authority or any other
     party or person is required to be obtained by such Purchaser (but in no
     event including any consent, approval or authorization of any governmental
     or regulatory authority necessitated by the status of the Company or its
     business) in order to execute, deliver and perform its obligations under
     this Agreement. Such Purchaser is not aware of any reason why the
     provisions of Section 2P will not be satisfied as to such Purchaser.

               (iii) Ownership of Securities. As of immediately prior to the
     date hereof, such Purchaser does not own any debt or equity securities
     issued by the Company.

               (iv) Investor Suitability. Such Purchaser is an "accredited
     investor" as such term is defined in Rule 501 promulgated under the
     Securities Act.

               (v) Disclosure of Information. Such Purchaser acknowledges that
     it or its representatives have been furnished with all information
     regarding the Company and its business, assets, results of operations and
     financial condition that the Purchaser has requested. Such Purchaser has
     had an opportunity to ask questions of and receive answers from the Company
     regarding the Company and its business, assets, results of operations, and
     financial condition and the terms and conditions of the issuance of the
     Securities; however, no representations or warranties have been made by the
     Company to the Purchasers in their capacity as Purchasers except as are set
     forth in this Agreement. NOTHING CONTAINED IN THIS SECTION 8E(v) AND NO
     INVESTIGATION, OR NEGLIGENCE OF THE PURCHASER IN CONNECTION THEREWITH, BY
     PURCHASERS SHALL IN ANY WAY AFFECT THE PURCHASERS' RIGHT TO RELY UPON THE
     COMPANY'S REPRESENTATIONS AND COVENANTS CONTAINED IN THIS AGREEMENT.

               (vi) Investment Experience. Such Purchaser represents that it has
     such knowledge, experience and skill in evaluating and investing in common
     and preferred stocks and other securities, based on actual participation in
     financial, investment and business matters, so that each is capable of
     evaluating the merits and risks of an investment in the Preferred Stock and
     has such knowledge, experience and skill in financial and business maters
     that each is capable of evaluating the merits and risks of the investment
     in the Company and the suitability of the Preferred Stock as an investment
     and can bear the economic risk of an investment in the Preferred Stock.

               (vii) Brokerage. No broker, finder or other party is entitled to
     receive from such Purchaser, any brokerage or finder's fee or any other
     fee, commission or payment as a result of the transactions contemplated by
     this Agreement for which the Company could have any liability or
     responsibility.

               (viii) Purchase for Own Account. Such Purchaser is acquiring the
     Restricted Securities purchased hereunder or acquired pursuant hereto for
     its own account with the present intention of holding such securities for
     purposes of investment, and that

                                       41

<PAGE>

     it has no intention of selling such securities in a public distribution in
     violation of the federal securities laws or any applicable state securities
     laws; provided that nothing contained herein shall prevent any Purchaser or
     subsequent holders of Restricted Securities from transferring such
     securities in compliance with the provisions of Section 4 hereof.

          8F. Consent to Amendments. Except as otherwise expressly provided
herein, the provisions of this Agreement may be amended and the Company may take
any action herein prohibited, or omit to perform any act herein required to be
performed by it, only if the Company has obtained the prior written consent of
the Majority Holders outstanding at the time the amendment or waiver becomes
effective or, in the case of any amendment or waiver prior to the Closing, only
if the Company has obtained the consent of the Majority Purchasers; provided
that if any such amendment, modification or waiver would adversely affect any
holder of Preferred Stock, as the case may be, relative to the holders of
Preferred Stock voting in favor of such amendment, modification, or waiver, such
amendment, modification or waiver shall also require the written consent of the
holders of a majority of the Preferred stock, as the case may be, held by all
holders so adversely affected; provided further that if any such amendment,
modification or waiver is to a provision in this Agreement that requires a
specific vote to take an action thereunder or to take an action with respect to
the matters described therein, such amendment, modification or waiver shall not
be effective unless such vote is obtained with respect to such amendment,
modification or waiver. No other course of dealing between the Company and the
holder of any Preferred Stock or any delay in exercising any rights hereunder or
under the Articles of Incorporation, Certificate of Designation or Registration
Agreement shall operate as a waiver of any rights of any such holders. For
purposes of this Agreement, Preferred Stock held by the Company or any
Subsidiary shall not be deemed to be outstanding.

          8G. Survival of Representations and Warranties. All representations
and warranties contained herein or made in writing by any party in connection
herewith shall survive the execution and delivery of this Agreement and the
Closing of the transactions contemplated hereby, regardless of any investigation
made by any Purchaser or on its behalf.

          8H. Successors and Assigns. Except as otherwise expressly provided
herein, all covenants and agreements contained in this Agreement by or on behalf
of any of the Parties hereto shall bind and inure to the benefit of the
respective successors and assigns of the Parties hereto whether so expressed or
not. In addition, and whether or not any express assignment has been made, the
provisions of this Agreement which are for any Purchaser's benefit as a
purchaser or holder of Preferred Stock are also for the benefit of, and
enforceable by, any subsequent holder of such Preferred Stock.

          8I. Generally Accepted Accounting Principles. Where any accounting
determination or calculation is required to be made under this Agreement or the
exhibits hereto, such determination or calculation (unless otherwise provided)
shall be made in accordance with GAAP, except that if because of a change in
GAAP the Company would have to alter a previously utilized accounting method or
policy in order to remain in compliance with GAAP, such determination or
calculation shall continue to be made in accordance with the Company's previous
accounting methods and policies.

                                       42

<PAGE>

          8J. Severability. Whenever possible, each provision of this Agreement
shall be interpreted in such manner as to be effective and valid under
applicable law, but if any provision of this Agreement is held to be prohibited
by or invalid under applicable law, such provision shall be ineffective only to
the extent of such prohibition or invalidity, without invalidating the remainder
of this Agreement.

          8K. Counterparts. This Agreement may be executed simultaneously in two
or more counterparts (including by means of telecopied signature pages), any one
of which need not contain the signatures of more than one party, but all such
counterparts taken together shall constitute one and the same Agreement.

          8L. Descriptive Headings; Interpretation. The descriptive headings and
captions used in this Agreement and the table of contents to this Agreement are
for convenience and reference purposes only and shall not constitute a
substantive part of, or affect in any way the meaning or interpretation of, this
Agreement. Any capitalized terms used in any Schedule or Exhibit attached hereto
or delivered in connection herewith and not otherwise defined therein shall have
the meanings set forth in this Agreement. The use of the word "including" herein
shall mean "including without limitation." The Parties intend that each
representation, warranty and covenant contained herein shall have independent
significance. If any Party has breached any representation, warranty or covenant
contained herein in any respect, the fact that there exists another
representation, warranty or covenant relating to the same subject matter
(regardless of the relative levels of specificity) which the Party has not
breached shall not detract from or mitigate the fact that the Party is in breach
of the first representation, warranty or covenant.

          8M. Governing Law. The corporate law of the State of Delaware shall
govern all issues and questions concerning the relative rights and obligations
of the Company and its shareholders. All other issues and questions concerning
the construction, validity, enforcement and interpretation of this Agreement and
the Exhibits and Schedules hereto shall be governed by, and construed in
accordance with, the laws of the State of Delaware, without giving effect to any
choice of law or conflict of law rules or provisions (whether of the State of
Delaware or any other jurisdiction) that would cause the application of the laws
of any jurisdiction other than the State of Delaware.

                          REGISTRATION RIGHTS AGREEMENT

          THIS REGISTRATION RIGHTS AGREEMENT is made as of April 23, 2006,
between JDA Software Group, Inc., a Delaware corporation (the "Company"), and
the Investors (the "Investors") listed on the Schedule of Investors attached
hereto.

          The parties to this Agreement are parties to a Preferred Stock
Purchase Agreement, dated April 23, 2006 (the "Purchase Agreement"). In order to
induce the Investors to enter into the Purchase Agreement, the Company has
agreed to provide the registration rights set forth in this Agreement. The
execution and delivery of this Agreement is a condition to the closing under the
Purchase Agreement. Unless otherwise provided in this Agreement, capitalized
terms used herein shall have the meanings set forth in Section 8 hereof.

          The parties hereto agree as follows:

          1. Mandatory and Demand Registrations.

          (a) Mandatory Registration. The Company shall use its commercially
reasonable efforts to file with the SEC a registration statement on the
applicable SEC form with respect to the resale, whether underwritten or
otherwise, of the Registrable Securities by the holders thereof within 30
calendar days, but in no event more than 60 calendar days, of the closing date
of purchase of Registrable Securities pursuant to the Purchase Agreement (the
"Closing Date"). The Company shall use its commercially reasonable efforts to
respond to all SEC comments related to such registration statement within 10
calendar days of the receipt thereof, and shall use its commercially reasonable
efforts to cause such registration statement to be declared effective by the SEC
within 90 days of the Closing Date. The Company shall use its commercially
reasonable efforts to maintain the effectiveness of the registration effected
pursuant to this Section 1(a) at all time, subject only to the limitations on
effectiveness set forth in Section 4 below. The registration contemplated by
this Section 1(a) is referred to herein as the "Mandatory Registration."

          (b) Demand Registration. The holders of at least a majority of the
Registrable Securities then outstanding may request up to two registrations
under the Securities Act of all or any portion of their Registrable Securities
on Form S-1 or any similar long-form registration as the Company may elect
("Long-Form Registrations"), and the holders of at least 25% of the Registrable
Securities then outstanding may request an unlimited number of registrations
under the Securities Act of all or any portion of their Registrable Securities
on Form S-3 or any similar short-form registration as the Company may elect
("Short-Form Registrations"), if available; provided that to the extent the
registration statement contemplated by Section 1(a) is available for use with
respect to the transaction contemplated by such registration request, the
Company may require the requesting holders to use such registration statement in
lieu of filing an additional registration statement pursuant to this Section
1(b), and provided further that the aggregate offering value of the Registrable
Securities requested to be registered in any registration under this Section
1(b) must equal at least $10 million in any Long-Form Registration and at least
$2 million in any Short-Form Registration. Any registration contemplated by this
Section 1(b) is referred to herein as a "Demand Registration."

<PAGE>

          All requests for Demand Registrations shall be made by giving written
notice thereof to the Company (a "Demand Notice"). Each Demand Notice shall
specify the approximate number of Registrable Securities requested to be
registered. Within ten business days after receipt of any Demand Notice, the
Company shall give written notice of such requested registration to all other
holders of Registrable Securities and, subject to the terms of Section 1(f)
hereof, shall include in such registration (and in all related registrations and
qualifications under state blue sky laws or in compliance with other
registration requirements and in any related underwriting) all Registrable
Securities with respect to which the Company has received written requests for
inclusion therein within 15 business days after the delivery of the Company's
notice in accordance with Section 11(k) hereof.

          (c) Short-Form Registrations. The Mandatory Registration and any
Demand Registrations shall be Short-Form Registrations whenever the Company is
permitted to use any applicable short form and, if applicable, the managing
underwriters agree to the use of a Short-Form Registration, and the Company
shall use its commercially reasonable efforts to make Short-Form Registrations
on Form S-3 available for the sale of Registrable Securities. The holders of at
least a majority of the Registrable Securities requested to be included in the
Mandatory Registration or any Demand Registration that is a Short-Form
Registration may require the Company to file such Short-Form Registration with
the SEC in accordance with and pursuant to Rule 415 promulgated under the
Securities Act (or any successor rule then in effect) (a "Shelf Registration").
The Mandatory Registration shall be filed as a Shelf Registration. So long as
any such Shelf Registration is effective as required herein and in compliance
with the Securities Act and usable for resale of Registrable Securities, the
holders of at least 25% of the Registrable Securities shall be entitled to
demand any number of draw-downs (including underwritten draw-downs, provided
that the aggregate offering value of the Registrable Securities requested to be
included in such underwritten draw-down must equal at least $2 million) from the
shelf and, in connection with any such draw-down, the Company shall take all
customary and reasonable actions that the Company would take in connection with
an underwritten Demand Registration pursuant to this Section 1 (including,
without limitation, all actions referred to in Section 4 necessary to effectuate
such sale in the manner determined by the holders of at least a majority of the
Registrable Securities to be included in such underwritten draw-dawn) as any
holder reasonably requests. The Company shall use its reasonable efforts to
cause the registration statement or statements filed pursuant to a Short-Form
Registration to remain effective until such date as is the earlier of (i) the
date on which all Registrable Securities included in the registration statement
shall have been sold or shall have otherwise ceased to be Registrable Securities
and (ii) the date on which all remaining Registrable Securities may be sold
during any three month period without any restriction pursuant to Rule 144(k)
promulgated under the Securities Act after taking into account any holders'
status as an affiliate of the Company as determined by the counsel to the
Company pursuant to a written opinion letter addressed to the Company's transfer
agent to such effect.

          (d) Long-Form Registrations. A registration shall not be deemed to
have been effected for purposes of Section 1 and shall not count as the one of
the Demand Registrations permitted as a Long-Form Registration if the applicable
registration statement has not been declared effective and kept effective until
the earlier of (i) six months following the date on which such registration
statement was declared effective and (ii) the sale pursuant to such registration
statement of all Registrable Securities covered thereby; provided that in any
event

                                       2

<PAGE>

the Company shall pay all Registration Expenses in connection with any
registration initiated as a Demand Registration whether or not it has become
effective and whether or not such registration has counted as one of the
permitted Long-Form Registrations. All Demand Registrations that are Long-Form
Registrations shall be underwritten registrations unless otherwise requested by
the holders of at least a majority of the Registrable Securities included in the
applicable Long-Form Registration. In the event the Mandatory Registration must
be effected as a Long-Form Registration, such registration shall nonetheless be
filed a Shelf Registration and the Company shall use its commercially reasonable
efforts to keep such registration current and effective, including by filing
periodic post-effective amendments to update the financial statements contained
in such registration statement in accordance with Regulation S-X promulgated
under the Securities Act until the date on which all Registrable Securities
included in the registration statement shall have been sold.

          (e) Expenses. The Registration Expenses (as defined in Section 5(a)
hereof) in the Mandatory Registration and all Demand Registrations shall be paid
by the Company.

          (f) Priority. The Company shall not include in the Mandatory
Registration or any Demand Registration any securities which are not Registrable
Securities without the prior written consent of the holders of at least a
majority of the Registrable Securities included in such registration. If a
Demand Registration is an underwritten offering and the managing underwriters
advise the Company in writing that in their opinion the number of Registrable
Securities and, if permitted hereunder, other securities requested to be
included in such offering exceeds the number of Registrable Securities and other
securities, if any, which can be sold in an orderly manner in such offering
within a price range acceptable to the holders of at least a majority of the
Registrable Securities requested to be included in such offering, the Company
shall include in such registration, prior to the inclusion of any securities
which are not Registrable Securities, the number of Registrable Securities
requested to be included which in the opinion of such underwriters can be sold
in an orderly manner within the price range of such offering, pro rata among the
respective holders thereof on the basis of the amount of Registrable Securities
owned by each such holder.

          (g) Restrictions on Demand Registrations. The Company shall not be
obligated to effect any Demand Registration within 180 days after the effective
date of the Mandatory Registration or a previous Demand Registration or a
previous registration in which the holders of Registrable Securities were given
piggyback rights pursuant to Section 2.

          Notwithstanding the foregoing, the Company may postpone for up to 180
days the filing or the effectiveness of a registration statement for a Demand
Registration (but not, for the avoidance of doubt, the Mandatory Registration)
if the Company's board of directors determines in its reasonable good faith
judgment that such Demand Registration would reasonably be expected to have a
material adverse effect on any proposal or plan of the Company or any of its
Subsidiaries to engage in any acquisition of assets or any merger,
consolidation, tender offer, reorganization or other material transaction;
provided that in such event, the holders of Registrable Securities initially
requesting such Demand Registration shall be entitled to withdraw such request
and, if such request is withdrawn with respect to a Long-Form Registration, such
Demand Registration shall not count as one of the permitted Long-Form
Registrations hereunder and the Company shall pay all Registration Expenses in
connection with

                                       3

<PAGE>

such registration. The Company may delay a Demand Registration hereunder only
once in any twelve-month period.

          (h) Selection of Underwriters. The holders of a majority of the
Registrable Securities included in any Demand Registration or any underwritten
takedown off the registration statement filed pursuant to the Mandatory
Registration shall have the right to select the investment banker(s) and
manager(s) to administer the offering; provided, however, that such banker(s)
and manager(s) must be reasonably acceptable to the Company (its acceptance not
to be unreasonably withheld or delayed).

          (i) Other Registration Rights. The Company represents and warrants
that it is not a party to, or otherwise subject to, any other agreement granting
registration rights to any other Person with respect to any securities of the
Company. Except as provided in this Agreement, the Company shall not grant to
any Person the right to request the Company to register any equity securities of
the Company, or any securities convertible or exchangeable into or exercisable
for such securities, without the prior written consent of the holders of at
least a majority of the Registrable Securities; provided that without such
consent the Company may grant rights to other Persons to participate in
Piggyback Registrations so long as such rights are subordinate to the rights of
the holders of Registrable Securities with respect to such Piggyback
Registrations as provided in Sections 2(c) and 2(d) below. Any securities (other
than Registrable Securities) as to which the Company has granted contractual
registration rights shall be referred to as "Other Securities."

          2. Piggyback Registrations.

          (a) Right to Piggyback. Whenever the Company proposes to register any
of its securities under the Securities Act other than pursuant to a Demand
Registration and other than in connection with the registration of equity
securities issued or issuable pursuant to an employee equity option, purchase,
bonus or similar plan or pursuant to a merger, exchange offer or transaction of
the type specified in Rule 145(a) under the Securities Act, and the registration
form to be used may be used for the registration of Registrable Securities (a
"Piggyback Registration"), the Company shall give prompt written notice to all
holders of Registrable Securities of its intention to effect such a registration
and shall (subject to Sections 2(c) and 2(d)) include in such registration (and
in all related registrations or qualifications under blue sky laws or in
compliance with other registration requirements and in any related underwriting)
all Registrable Securities with respect to which the Company has received
written requests for inclusion therein within 20 days after the receipt of the
Company's notice.

          (b) Piggyback Expenses. The Registration Expenses in all Piggyback
Registrations shall be paid by the Company.

          (c) Priority on Primary Registrations. If a Piggyback Registration is
an underwritten primary registration on behalf of the Company, and the managing
underwriters advise the Company in writing that in their opinion the number of
securities requested to be included in such registration exceeds the number
which can be sold in an orderly manner in such offering within a price range
acceptable to the Company, the Company shall include in such registration (i)
first, the securities the Company proposes to sell, (ii) second, the Registrable

                                       4

<PAGE>

Securities requested to be included in such registration, pro rata among the
holders of such Registrable Securities on the basis of the number of shares
requested to be included therein by each such holder, and (iii) the Other
Securities requested to be included in such registration.

          (d) Priority on Secondary Registrations. If a Piggyback Registration
is an underwritten secondary registration on behalf of holders of the Company's
securities, and the managing underwriters advise the Company in writing that in
their opinion the number of securities requested to be included in such
registration exceeds the number which can be sold in an orderly manner in such
offering within a price range acceptable to the holders initially requesting
such registration, the Company shall include in such registration (i) first, the
securities requested to be included therein by the holders requesting such
registration and the Registrable Securities requested to be included in such
registration, pro rata among the holders of such securities on the basis of the
number of securities so requested to be included therein, and (ii) second, the
Other Securities requested to be included in such registration.

          (e) Selection of Underwriters. If any Piggyback Registration is an
underwritten offering, the selection of investment banker(s) and manager(s) for
the offering by the Company must be approved by the holders of at least a
majority of the Registrable Securities included in such Piggyback Registration,
which such approval shall not be unreasonably withheld or delayed.

          (f) Other Registrations. If the Company has previously filed a
registration statement with respect to Registrable Securities pursuant to
Section 1 or pursuant to this Section 2, and if such previous registration has
not been withdrawn or abandoned, the Company shall not file or cause to be
effected any other registration of any of its equity securities or securities
convertible or exchangeable into or exercisable for its equity securities under
the Securities Act (except pursuant to a registration on Form S-4, Form S-8 or
any successor form), whether on its own behalf or at the request of any holder
or holders of such securities, until a period of at least 90 days has elapsed
from the effective date of such previous registration.

          3. Holdback Agreements; Cooperation.

          (a) Each holder of Registrable Securities shall not effect any public
sale or distribution (including sales pursuant to Rule 144 promulgated under the
Securities Act) of equity securities of the Company, or any securities
convertible into or exchangeable or exercisable for such securities, during (i)
with respect to any underwritten Demand Registration or any underwritten
Piggyback Registration in which Registrable Securities are included, the seven
days prior to and the 90-day period beginning on the effective date of such
registration (or such shorter period as agreed to by the managing underwriters),
and (ii) upon notice from the Company of the commencement of an underwritten
distribution in connection with any Shelf Registration, the seven days prior to
and the 90-day period beginning on the date of commencement of such distribution
(or such shorter period as agreed to by the managing underwriters), in each case
except as part of such underwritten registration and in each case unless the
underwriters managing the registered public offering otherwise agree.

          (b) The Company (i) shall not effect any public sale or distribution
of its equity securities, or any securities convertible into or exchangeable or
exercisable for such

                                       5

<PAGE>

securities (except pursuant to registration on Form S-4, Form S-8 or any
successor form), during (A) with respect to any underwritten Demand Registration
or any underwritten Piggyback Registration in which Registrable Securities are
included, the seven days prior to and the 90-day period (or such shorter period
as agreed to by the underwriters) beginning on the effective date of such
registration, and (B) upon notice from any holder(s) of Registrable Securities
subject to a Shelf Registration that such holder(s) intend to effect an
underwritten distribution of Registrable Securities pursuant to such Shelf
Registration (upon receipt of which, the Company will promptly notify all other
holders of Registrable Securities of the date of commencement of such
distribution), the seven days prior to and the 90-day period (or such shorter
period as agreed to by the underwriters) beginning on the date of commencement
of such distribution, and (ii) shall cause each holder or group of affiliated
holders who purchases from the Company at any time after the date of this
Agreement at least 10% of its Common Stock, or any securities convertible into
or exchangeable or exercisable for at least 10% of its Common Stock, (other than
purchases in a registered public offering or pursuant to an underwritten
offering under Rule 144A or pursuant to equity subscription agreements, stock
option agreements, stock appreciation rights, phantom stock plans or similar
rights or plans in effect on the date of this Agreement) (a "Private Purchaser")
to agree not to effect any public sale or distribution (including sales pursuant
to Rule 144) of any such securities during such 90 day periods (or such shorter
or longer periods as provided below) so long as (x) the holders of Registrable
Securities continue to hold at least 50% of the Registrable Securities held as
of the date hereof (provided that a Private Purchaser shall be subject to such
periods only twice in any twelve-month period) and (y) such Private Purchaser
has entered into an agreement with the Company limiting such Private Purchaser's
right or ability to effectuate a public sale or distribution during an
underwritten registered offering by the Company (provided that such Private
Purchaser shall be limited for the same period of time that it is limited by
with respect to an underwritten registered offering by the Company (which may be
greater or less than the 90 day period set forth above), in each case except as
part of such underwritten registration and in each case unless the underwriters
managing the registered public offering otherwise agree.

          (c) Each holder of Registrable Securities agrees to cooperate with the
Company as reasonably requested by the Company in connection with the
preparation and filing hereunder of any registration statement, prospectus or
preliminary prospectus or any amendment thereof or supplement thereto.

          4. Registration Procedures. In the Mandatory Registration and whenever
the holders of Registrable Securities have requested that any Registrable
Securities be registered pursuant to this Agreement, the Company shall use its
reasonable efforts to effect the registration and the sale of such Registrable
Securities in accordance with the intended method of disposition thereof, and
pursuant thereto the Company shall as expeditiously as practicable:

          (b) notify each holder of Registrable Securities of the effectiveness

the case of a Shelf Registration, a period ending on such date as is the earlier
of (i) the date on which all Registrable Securities included in the registration
statement shall have been sold or shall have otherwise ceased to be Registrable
Securities and (ii) the date on which all remaining Registrable Securities may
be sold during any three month period without any restriction pursuant to Rule
144(k) promulgated under the Securities Act after taking into account any
holders' status as an affiliate of the Company as determined by the counsel to
the Company pursuant to a written opinion letter addressed to the Company's
transfer agent to such effect) and comply with the provisions of the Securities
Act with respect to the disposition of all securities covered by such
registration statement during such period in accordance with the intended
methods of disposition by the sellers thereof set forth in such registration
statement;

          (c) furnish to each seller of Registrable Securities such number of
copies of the prospectus included in such registration statement (including each
preliminary prospectus), each amendment and supplement thereto and such other
documents as such seller may reasonably request in order to facilitate the
disposition of the Registrable Securities owned by such seller;

          (d) use its best efforts to register or qualify such Registrable
Securities under such other securities or blue sky laws of such jurisdictions as
any seller reasonably requests and do any and all other acts and things which
may be reasonably necessary or advisable to enable such seller to consummate the
disposition in such jurisdictions of the Registrable Securities owned by such
seller (provided that the Company shall not be required to (i) qualify generally
to do business in any jurisdiction where it would not otherwise be required to
qualify but for this subparagraph, (ii) subject itself to taxation in any such
jurisdiction or (iii) consent to general service of process in any such
jurisdiction);

          (e) notify each seller of such Registrable Securities, at any time
when a prospectus relating thereto is required to be delivered under the
Securities Act, of the happening of any event as a result of which the
prospectus included in such registration statement contains an untrue statement
of a material fact or omits any fact necessary to make the statements therein
not misleading, and, at the request of any such seller, the Company shall
prepare a supplement or amendment to such prospectus so that, as thereafter
delivered to the purchasers of such Registrable Securities, such prospectus
shall not contain an untrue statement of a material fact or omit to state any
fact necessary to make the statements therein not misleading;

          (f) cause all such Registrable Securities to be listed on each
securities exchange on which similar securities issued by the Company are then
listed and, if not so listed, to be listed on the NASD automated quotation
system and, if listed on the NASD automated quotation system, use its reasonable
efforts to secure designation of all such Registrable Securities covered by such
registration statement as a Nasdaq "national market system security"

                                       7

<PAGE>

within the meaning of Rule 11Aa2-1 of the SEC or, failing that, to secure Nasdaq
authorization for such Registrable Securities and, without limiting the
generality of the foregoing, use its reasonable efforts to arrange for at least
two market makers to register as such with respect to such Registrable
Securities with the NASD;

          (g) provide a transfer agent and registrar for all such Registrable
Securities not later than the effective date of such registration statement;

          (h) enter into such customary agreements (including underwriting
agreements in customary form) and take all such other actions as the holders of
a majority of the Registrable Securities being sold or the underwriters, if any,
reasonably request in order to expedite or facilitate the disposition of such
Registrable Securities (including preparing for and participating in such number
of "road shows" as the underwriters managing such offering may reasonably
request);

          (i) make available for inspection by any seller of Registrable
Securities, any underwriter participating in any disposition pursuant to such

any such seller or underwriter, all financial and other records, pertinent
corporate documents and properties of the Company, and cause the Company's
officers, directors, employees and independent accountants to supply all
information reasonably requested by any such seller, underwriter, attorney,
accountant or agent in connection with such registration statement (unless the
Company can demonstrate that such Person already possesses the requested
information);

          (j) otherwise use its best efforts to comply with all applicable rules
and regulations of the SEC, and make available to its security holders, as soon
as reasonably practicable, an earnings statement covering the period of at least
twelve months beginning with the first day of the Company's first full calendar
quarter after the effective date of the registration statement, which earnings
statement shall satisfy the provisions of Section 11(a) of the Securities Act
and Rule 158 thereunder;

          (k) permit any holder of Registrable Securities which holder, in its
sole and exclusive judgment, might be deemed to be an underwriter or a
controlling person of the Company, to participate in the preparation of such
registration or comparable statement and to require the insertion therein of
material, furnished to the Company in writing in a timely manner, which in the
reasonable judgment of such holder and its counsel should be included;

          (l) in the event of the issuance of any stop order suspending the
effectiveness of a registration statement, or of any order suspending or
preventing the use of any related prospectus or suspending the qualification of
any common stock included in such registration statement for sale in any
jurisdiction, the Company shall use its reasonable efforts promptly to obtain
the withdrawal of such order;

          (m) use its reasonable efforts to cause such Registrable Securities
covered by such registration statement to be registered with or approved by such
other governmental agencies or authorities as may be necessary to enable the
sellers thereof to consummate the disposition of such Registrable Securities;
and

                                       8

<PAGE>

          (n) in the case of an underwritten offering, use reasonable efforts to
obtain a cold comfort letter from the Company's independent public accountants
in customary form and covering such matters of the type customarily covered by
cold comfort letters as the holders of at least a majority of the Registrable
Securities being sold reasonably request.

          5. Registration Expenses.

          (a) All expenses incident to the Company's performance of or
compliance with this Agreement, including without limitation all registration
and filing fees, fees and expenses of compliance with securities or blue sky
laws, printing expenses, messenger and delivery expenses, fees and disbursements
of custodians, and fees and disbursements of counsel for the Company and, to the
extent provided in Section 5(b), fees and disbursements of counsel for any
holder of Registrable Securities and all independent certified public
accountants, underwriters (excluding discounts and commissions) and other
Persons retained by the Company (all such expenses being herein called
"Registration Expenses"), shall be borne by the Company as provided in this
Agreement, except that the Company shall, in any event, pay its internal
expenses (including, without limitation, all salaries and expenses of its
officers and employees performing legal or accounting duties), the expense of
any annual audit or quarterly review, the expense of any liability insurance
which the Company has agreed to obtain in its reasonable discretion and the
expenses and fees for listing the securities to be registered on each securities
exchange on which similar securities issued by the Company are then listed or on
the NASD automated quotation system.

          (b) In connection with each Demand Registration and each Piggyback
Registration, the Company shall reimburse the holders of Registrable Securities
included in such registration for the reasonable fees and disbursements of one
counsel chosen by the holders of a majority of the Registrable Securities
included in such registration upon submission of reasonably itemized statements
for such counsel rendering services customarily performed by counsel for selling
shareholders.

          (c) To the extent any expenses relating to a registration hereunder
are not required to be paid by the Company, each holder of securities included
in any registration hereunder shall pay those expenses allocable to the
registration of such holder's securities so included, and any expenses not so
allocable shall be borne by all sellers of securities included in such
registration in proportion to the aggregate selling price of the securities to
be so registered.

          (d) Any obligation to pay Registration Expenses or other expenses
provided for in this Agreement shall survive the termination of this Agreement.

          6. Indemnification.

          (a) The Company agrees to indemnify, to the extent permitted by law,
each holder of Registrable Securities, its officers, directors, employees,
agents, Affiliates and each Person who controls such holder (within the meaning
of the Securities Act and the Securities Exchange Act) against all losses,
claims, actions, damages, liabilities and expenses caused by (i) any untrue or
alleged untrue statement of material fact contained in any registration
statement, prospectus or preliminary prospectus or any amendment thereof or
supplement thereto or any

                                       9

<PAGE>

omission or alleged omission of a material fact required to be stated therein or
necessary to make the statements therein not misleading, except to the extent
that such untrue statements relate to such holder and was reviewed and approved
of in writing by such holder for use in any registration statement, prospectus
or preliminary prospectus or any amendment thereof or supplement thereto, or
(ii) any violation by the Company of any rule or regulation promulgated under
the Securities Act applicable to the Company and relating to action or inaction
required of the Company in connection with any such registration, qualification
or compliance, and to pay to each holder of Registrable Securities, its officers
and directors and each Person who controls such holder (within the meaning of
the Securities Act), as incurred, any legal and any other expenses reasonably
incurred in connection with investigating, preparing or defending any such
claim, loss, damage, liability or action, except insofar as the same are caused
by or contained in any information furnished in writing to the Company by such
holder expressly for use therein or by such holder's failure to deliver a copy
of the registration statement or prospectus or any amendments or supplements
thereto after the Company has furnished such holder with such number of copies
of the same as was previously requested by such holder. In connection with an
underwritten offering, the Company shall indemnify such underwriters, their
officers, directors, employees, agents and each Person who controls such
underwriters (within the meaning of the Securities Act and the Securities
Exchange Act) to the same extent as provided above with respect to the
indemnification of the holders of Registrable Securities, but the provisions of
the underwriting agreement with such underwriters, if different, shall govern.

          (b) In connection with any registration statement in which a holder of
Registrable Securities is participating, each such holder shall furnish to the
Company in writing such information and affidavits as the Company reasonably
requests for use in connection with any such registration statement or
prospectus and, to the extent permitted by law, shall indemnify the Company, its
directors, officers, employees, agents, Affiliates and each Person who controls
the Company (within the meaning of the Securities Act and the Securities
Exchange Act) against any losses, claims, damages, liabilities and expenses
resulting from any untrue or alleged untrue statement of material fact contained
in the registration statement, prospectus or preliminary prospectus or any
amendment thereof or supplement thereto or any omission or alleged omission of a
material fact required to be stated therein or necessary to make the statements
therein not misleading, but only to the extent that such untrue statement or
omission is contained in any information or affidavit so furnished in writing by
such holder; provided that the obligation to indemnify shall be individual and
ratable, not joint and several, for each holder and shall be limited to the net
amount of proceeds received by such holder from the sale of Registrable
Securities pursuant to such registration statement.

          (c) Any Person entitled to indemnification hereunder shall (i) give
prompt written notice to the indemnifying party of any claim with respect to
which it seeks indemnification (provided that the failure to give prompt notice
shall not impair any Person's right to indemnification hereunder to the extent
such failure has not prejudiced the indemnifying party) and (ii) unless in such
indemnified party's reasonable judgment a conflict of interest between such
indemnified and indemnifying parties may exist with respect to such claim,
permit such indemnifying party to assume the defense of such claim with counsel
reasonably satisfactory to the indemnified party. If such defense is assumed,
the indemnifying party shall not be subject to any liability for any settlement
made by the indemnified party without its consent (but such consent shall not be
unreasonably withheld). An indemnifying party who is

                                       10

<PAGE>

not entitled to, or elects not to, assume the defense of a claim shall not be
obligated to pay the fees and expenses of more than one counsel for all parties
indemnified by such indemnifying party with respect to such claim, unless in the
reasonable judgment of any indemnified party a conflict of interest may exist
between such indemnified party and any other of such indemnified parties with
respect to such claim. In such instance, the conflicting indemnified parties
shall have a right to retain one separate counsel, chosen by the holders of a
majority of the Registrable Securities included in the registration, at the
expense of the indemnifying party. No indemnifying party, in the defense of such
claim or litigation, shall, except with the consent of each indemnified party,
consent to the entry of any judgment or enter into any settlement which does not
include as an unconditional term thereof the giving by the claimant or plaintiff
to such indemnified party of a release from all liability in respect to such
claim or litigation.

          (d) The indemnification provided for under this Agreement shall remain
in full force and effect regardless of any investigation made by or on behalf of
the indemnified party or any officer, director, employee, agent, Affiliate or
controlling Person of such indemnified party and shall survive the transfer of
securities and the termination of this Agreement. The Company also agrees to
make such provisions, as are reasonably requested by any indemnified party, for
contribution to such party in the event the Company's indemnification is
unavailable for any reason.

          7. Participation in Underwritten Registrations. No Person may
participate in any registration hereunder that is underwritten unless such
Person (i) agrees to sell such Person's securities on the basis provided in any
underwriting arrangements approved by the Person or Persons entitled hereunder
to approve such arrangements and (ii) completes and executes all questionnaires,
powers of attorney, indemnities, underwriting agreements and other documents
required under the terms of such underwriting arrangements in a timely manner;
provided that no holder of Registrable Securities included in any underwritten
registration shall be required to make any representations or warranties to the
Company or the underwriters (other than representations and warranties regarding
such holder, such holder's title to the securities and such holder's intended
method of distribution) or to undertake any indemnification obligations to the
Company or the underwriters with respect thereto, except as otherwise provided
in Section 6 hereof.

required to be filed by it under the Securities Act and the Securities Exchange
Act and the rules and regulations adopted by the SEC thereunder and shall take
such further action as any holder or holders of Registrable Securities may
reasonably request, all to the extent required to enable such

                                       13

holders to sell Registrable Securities pursuant to Rule 144 adopted by the SEC
under the Securities Act (as such rule may be amended from time to time) or any
similar rule or regulation hereafter adopted by the SEC. Upon request, the
Company shall deliver to any holder of Registrable Securities a written
statement as to whether it has complied with such requirements. The Company
shall at all times use its best efforts to cause the Common Stock into which the
Preferred Stock is convertible to be listed on one or more of the New York Stock
Exchange, the American Stock Exchange or the Nasdaq National Market System.

          (d) Adjustments Affecting Registrable Securities. The Company shall
not take any action, or permit any change to occur, with respect to its
securities which would adversely affect the ability of the holders of
Registrable Securities to include such Registrable Securities in a registration
undertaken pursuant to this Agreement or which would adversely affect the
marketability of such Registrable Securities in any such registration
(including, without limitation, effecting a stock split or a combination of
shares).

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

          (f) Consent to Amendments. Except as otherwise expressly provided
herein, the provisions of this Agreement may be amended or modified and the
Company may take any action herein prohibited, or omit to perform any act herein
required to be performed by it, only if the Company has obtained the written
consent of the holders of a majority of the Registrable Securities outstanding
at the time the amendment or waiver becomes effective; provided that if any such
amendment, modification or waiver is to a provision in this Agreement that
requires a specific vote to take an action thereunder or to take an action with
respect to the matters described therein, such amendment, modification or waiver
shall not be effective unless such vote is obtained with respect to such
amendment, modification or waiver. No other course of dealing between the
Company and the holder of any Registrable Securities or any delay in exercising
any rights hereunder shall operate as a waiver of any rights of any such
holders. For purposes of this Agreement, Registrable Securities held by the
Company or any Subsidiaries shall not be deemed to be outstanding.

          (g) Successors and Assigns. All covenants and agreements in this
Agreement by or on behalf of any of the parties hereto shall bind and inure to
the benefit of the respective successors and assigns of the parties hereto
whether so expressed or not. In addition, whether or not any express assignment
has been made, the provisions of this Agreement which are for the benefit of
purchasers or holders of Registrable Securities are also for the benefit of, and
enforceable by, any subsequent holder of Registrable Securities.

                                       14

          (h) Severability. Whenever possible, each provision of this Agreement
shall be interpreted in such manner as to be effective and valid under
applicable law, but if any provision of this Agreement is held to be prohibited
by or invalid under applicable law, such provision shall be ineffective only to
the extent of such prohibition or invalidity, without invalidating the remainder
of this Agreement.

          (i) Counterparts. This Agreement may be executed simultaneously in two
or more counterparts (including by means of telecopied signature pages), any one
of which need not contain the signatures of more than one party, but all such
counterparts taken together shall constitute one and the same Agreement.

          (j) Descriptive Headings. The descriptive headings of this Agreement
are inserted for convenience only and do not constitute a substantive part of
this Agreement. Whenever required by the context, any pronoun used in this
Agreement shall include the corresponding masculine, feminine or neuter forms,
and the singular forms of nouns, pronouns, and verbs shall include the plural
and vice versa. Reference to any agreement, document, certificate, or instrument
means such agreement, document, certificate or instrument as the same is
amended, waived or otherwise modified from time to time in accordance with the
terms thereof and, if applicable, hereof. Except as otherwise provided in this
Agreement, words such as "herein," "hereunder," "hereof" and the like shall be
deemed to refer to this Agreement as a whole and not to any particular document
or article, Section, paragraph or other portion of a document. The use of the
words "include" or "including" in this Agreement shall be by way of example
rather than by limitation. The use of the words "or," "either" or "any" shall
not be exclusive.

          (k) Governing Law. The corporate law of the State of Delaware shall
govern all issues and questions concerning the relative rights of the Company
and its stockholders. All other issues and questions concerning the
construction, validity, interpretation and enforcement of this Agreement and the
exhibits and schedules hereto shall be governed by, and construed in accordance
with, the laws of the State of Delaware, without giving effect to any choice of
law or conflict of law rules or provisions (whether of the State of Delaware or
any other jurisdiction) that would cause the application of the laws of any
jurisdiction other than the State of Delaware.

          (l) Notices. All notices, demands or other communications to be given
or delivered under or by reason of the provisions of this Agreement shall be in
writing and shall be deemed to have been given when delivered personally to the
recipient, telecopied to the recipient (with hard copy sent by overnight courier

          (m) Business Days. If any time period for giving notice or taking

          (n) Delivery by Facsimile. This Agreement, the agreements referred to
herein and each other agreement or instrument entered into in connection
herewith or therewith or contemplated hereby or thereby, and any amendments
hereto or thereto, to the extent signed and delivered by means of a facsimile
machine, shall be treated in all manner and respects as an original agreement or
instrument and shall be considered to have the same binding legal effect as if
it were the original signed version thereof delivered in person. At the request
of any party hereto or to any such agreement or instrument, each other party
hereto or thereto shall reexecute originals forms thereof and deliver them to
all other parties. No party hereto or to any such agreement or instrument shall
raise the use of a facsimile machine to deliver a signature or the fact that any
signature or agreement or instrument was transmitted or communicated through the
use of a facsimile machine as a defense to the formation or enforceability of a
contract and each such party forever waives any such defense.
