AGREEMENT

The Parties to this Agreement, intending to be legally bound, agree as follows:

ARTICLE I

THE OFFER

Section 1.1    The Offer.

(a)    Commencement of the Offer. Provided that this Agreement shall not have been terminated in accordance with Section 8, as promptly as practicable after the date of this Agreement but in no event later than ten (10) business days following the date of this Agreement, Purchaser shall (and Parent shall cause Purchaser to) commence (within the meaning of Rule 14d-2 under the Exchange Act) the Offer.

(d)    Termination of Offer. In the event that this Agreement is terminated pursuant to Section 8.1, Purchaser shall (and Parent shall cause Purchaser to) promptly (and, in any event, within 24 hours of such termination), irrevocably and unconditionally terminate the Offer and shall not acquire any Shares pursuant to the Offer. If the Offer is terminated or withdrawn by Purchaser, Purchaser shall promptly return, and shall cause any depository acting on behalf of Purchaser to return, in accordance with applicable Legal Requirements, all tendered Shares to the registered holders thereof.

Each of Parent and Purchaser shall respond promptly to any comments of the SEC or its staff with respect to the Offer Documents or the Offer. Parent and Purchaser shall provide the Company and its counsel a reasonable opportunity to participate in the formulation of any response to any such comments of the SEC or its staff and a reasonable opportunity to participate in any discussions with the SEC or its staff concerning such comments.

If, between the date of this Agreement and the Offer Acceptance Time, the outstanding Shares are changed into a different number or class of shares by reason of any stock split, division or subdivision of shares, stock dividend, reverse stock split, consolidation of shares, reclassification, recapitalization or other similar transaction, then the Offer Price shall be appropriately adjusted; it being understood that nothing in this Section 1.1(g) shall be construed to permit the Company to take any action that is expressly prohibited by the terms of this Agreement.

Section 2.6    Surrender of Certificates; Stock Transfer Books.

(a)    Prior to the Offer Acceptance Time, Parent shall designate a bank or trust company reasonably acceptable to the Company to act as agent (the “Depository Agent”) for the holders of Shares to receive the funds to which holders of such shares shall become entitled pursuant to Sections 1.1(b) and (f) and to act as agent (the “Paying Agent”) for the holders of Shares to receive the funds to which holders of such shares shall become entitled pursuant to Section 2.5. The Paying Agent Agreement pursuant to which Parent shall appoint the Paying Agent shall be in form and substance reasonably acceptable to the Company. At or promptly following the Offer Acceptance Time, Parent shall deposit, or shall cause to be deposited, with the Depository Agent cash sufficient to make payment of the cash consideration payable pursuant to Sections 1.1(b) and (f), and with the Paying Agent cash sufficient to make payment of the cash consideration payable pursuant to Section 2.5 (together, the “Payment Fund”).

7

(b)    Promptly after the Effective Time (but in no event later than three business days thereafter), the Surviving Corporation shall cause to be mailed to each Person who was, at the Effective Time, a holder of record of the Shares entitled to receive the Merger Consideration pursuant to Section 2.5 a form of letter of transmittal (which shall be in reasonable and customary form and shall specify that delivery shall be effected, and risk of loss and title to the certificates evidencing such shares (the “Certificates”) shall pass, only upon proper delivery of the Certificates (or effective affidavits of loss in lieu thereof) to the Paying Agent) and instructions for use in effecting the surrender of the Certificates or Book-Entry Shares pursuant to such letter of transmittal. Upon surrender to the Paying Agent of Certificates (or effective affidavits of loss in lieu thereof) or Book-Entry Shares, together with such letter of transmittal, duly completed and validly executed in accordance with the instructions thereto, and such other documents as may be reasonably required pursuant to such instructions, the holder of such Certificates or Book-Entry Shares shall be entitled to receive in exchange therefor the Merger Consideration for each Share formerly evidenced by such Certificates or Book-Entry Shares, and such Certificates and Book-Entry Shares shall then be canceled. No interest shall accrue or be paid on the Merger Consideration payable upon the surrender of any Certificates or Book-Entry Shares for the benefit of the holder thereof. If the payment of any Merger Consideration is to be made to a Person other than the Person in whose name the surrendered Certificates formerly evidencing the Shares is registered on the stock transfer books of the Company, it shall be a condition of payment that the Certificate so surrendered shall be endorsed properly or otherwise be in proper form for transfer and that the Person requesting such payment shall have paid all transfer and other similar Taxes required by reason of the payment of the Merger Consideration to a Person other than the registered holder of the Certificate surrendered, or shall have established to the satisfaction of the Surviving Corporation that such Taxes either have been paid or are not applicable. Payment of the applicable Merger Consideration with respect to Book-Entry Shares shall only be made to the Person in whose name such Book-Entry Shares are registered. Until surrendered as contemplated by this Section 2.6(b), each Certificate and Book-Entry Share shall be deemed at any time after the Effective Time to represent only the right to receive upon such surrender the amount of cash, without interest, into which the Shares theretofore represented by such Certificate or Book-Entry have been converted pursuant to Section 2.5.

(c)    At any time following 12 months after the Effective Time, the Surviving Corporation shall be entitled to require the Paying Agent to deliver to it any funds which had been made available to the Paying Agent and not disbursed to holders of Certificates or Book-Entry Shares (including all interest and other income received by the Paying Agent in respect of all funds made available to it), and, thereafter, such holders shall be entitled to look to the Surviving Corporation (subject to abandoned property, escheat and other similar Legal Requirements) only as general creditors thereof with respect to the Merger Consideration that may be payable upon due surrender of the Certificates or Book-Entry Shares held by them. Neither the Surviving Corporation nor the Paying Agent shall be liable to any holder of Certificates or Book-Entry Shares for the Merger Consideration delivered in respect of such share to a public official pursuant to any abandoned property, escheat or other similar Legal Requirements. Any amounts remaining unclaimed by such holders at such time at which such amounts would otherwise escheat to or become property of any Governmental Body shall become, to the extent permitted by applicable Legal Requirements, the property of the Surviving Corporation or its designee, free and clear of all claims or interest of any Person previously entitled thereto.

8

(d)    At the close of business on the day of the Effective Time, the stock transfer books of the Company with respect to the Shares shall be closed and thereafter there shall be no further registration of transfers of Shares on the records of the Company. From and after the Effective Time, the holders of the Shares outstanding immediately prior to the Effective Time shall cease to have any rights with respect to such shares except as otherwise provided herein or by applicable Legal Requirements.

(e)    Each of the Paying Agent, Parent, Purchaser, and the Surviving Corporation shall be entitled to deduct and withhold from any cash amounts payable pursuant to this Agreement to any holder of Shares or Company Options such amounts as it is required to deduct or withhold therefrom under applicable Legal Requirements. Any such amounts deducted or withheld and remitted to the appropriate Governmental Body in accordance with applicable Legal Requirements shall be treated for all purposes under this Agreement as having been paid to the Person to whom such amounts would otherwise have been paid.

(f)    If any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the Person claiming such Certificate to be lost, stolen or destroyed and, if required by the Surviving Corporation, the posting by such Person of a bond, in such reasonable amount as Parent may direct, as indemnity against any claim that may be made against it with respect to such Certificate (which shall not exceed the Merger Consideration payable with respect to such Certificate), the Paying Agent will pay (less any amounts entitled to be deducted or withheld pursuant to Section 2.6(e)), in exchange for such lost, stolen or destroyed Certificate, the applicable Merger Consideration to be paid in respect of the Shares formerly represented by such Certificate, as contemplated by this Section 2.

Section 2.7    Dissenters’ Rights. Shares outstanding immediately prior to the Effective Time, and held by holders who are entitled to demand appraisal rights under Section 262 of the DGCL and have properly exercised and perfected their respective demands for appraisal of such shares in the time and manner provided in Section 262 of the DGCL and, as of the Effective Time, have neither effectively withdrawn nor lost their rights to such appraisal and payment under the DGCL (the “Dissenting Shares”), shall not be converted into the right to receive Merger Consideration, but shall, by virtue of the Merger, be entitled to only such consideration as shall be determined pursuant to Section 262 of the DGCL; provided that if any such holder shall have failed to perfect or shall have effectively withdrawn or lost such holder’s right to appraisal and payment under the DGCL, such holder’s Shares shall be deemed to have been converted as of the Effective Time into the right to receive the Merger Consideration (less any amounts entitled to be deducted or withheld pursuant to Section 2.6(e)), and such shares shall not be deemed to be Dissenting Shares. Within ten days after the Effective Time, the Surviving Corporation shall provide each of the holders of Shares with the notice contemplated by Section 262 of the DGCL. The Company shall give prompt written notice to Parent of any demands received by the Company for appraisal of any Shares, and Parent shall have the right to participate in, and direct all negotiations and Legal Proceedings with respect to such demands. The Company shall not, without the prior written consent of Parent, make any payment with respect to, or settle or offer to settle, any such demands, or agree to do any of the foregoing. Prior

9

to the Effective Time, Parent shall not, except with the prior written consent of the Company, require the Company to make any payment with respect to any demands for appraisal or offer to settle or settle any such demands.

Section 2.8    Treatment of Company Options.

(a)    Each Company Option that is outstanding as of immediately prior to the Effective Time shall accelerate and become fully vested and exercisable effective immediately prior to, and contingent upon, the Effective Time. As of the Effective Time, by virtue of the Merger and without any further action on the part of the holders thereof, Parent, Purchaser or the Company, each Company Option that is then outstanding and unexercised as of immediately before the Effective Time shall be cancelled and converted into the right to receive cash in an amount equal to the product of (i) the total number of Shares subject to such fully vested Company Option immediately prior to the Effective Time, multiplied by (ii) the excess of (x) the Merger Consideration over (y) the exercise price payable per Share under such Company Option, which amount shall be paid in accordance with Section 2.8(b) (the “Option Consideration”). Any Company Option that has an exercise price that equals or exceeds the Merger Consideration shall be canceled for no consideration.

(b)    On the Surviving Corporation’s next regularly scheduled payroll date following the Effective Time (but no later than ten (10) business days after the Effective Time), Parent shall, or shall cause the Surviving Corporation or a Subsidiary of the Surviving Corporation to, pay through the Surviving Corporation’s or the applicable Subsidiary’s payroll the aggregate Option Consideration payable with respect to Company Options held by current or former employees of the Company (net of any withholding Taxes required to be deducted and withheld by applicable Legal Requirements in accordance with Section 2.6(e)); provided, however, that to the extent the holder of a Company Option is not, and was not at any time during the vesting period of the Company Option, an employee of the Company for employment tax purposes, the Option Consideration payable pursuant to this Section 2.8 with respect to such Company Option shall be deposited in the Payment Fund and paid by the Paying Agent in the manner described in Section 2.6.

Section 2.9    Treatment of Company Warrants. At the Effective Time, by virtue of the Merger and without any further action on the part of Parent, the Company, the holder of any Company Warrant or any other Person, the Company Warrants will be converted into the right to receive the Merger Consideration less the applicable exercise price in respect of the shares of Company Common Stock underlying such Company Warrants, and the holders of such Company Warrants, in lieu of Shares immediately theretofore purchasable and receivable upon the exercise of the rights represented by the Company Warrant, will be entitled only to receive the Merger Consideration less the applicable exercise price in respect of each share of Company Common Stock underlying such Company Warrants and will have no other rights pursuant to each such holder’s ownership of such Company Warrants.

Section 2.10    Further Action. If, at any time after the Effective Time, any further action is reasonably determined by Parent to be necessary or desirable to carry out the purposes of this Agreement or to vest the Surviving Corporation with full right, title and possession of and to all rights and property of Purchaser and the Company, the officers and directors of the Surviving Corporation and Parent shall be fully authorized (in the name of Purchaser, in the name of the Company and otherwise) to take such action.

Section 4.2    Purchaser. Purchaser was formed solely for the purpose of engaging in the Transactions and activities incidental thereto and has not engaged in any business activities or conducted any operations other than in connection with the Transactions and those incident to its formation. Either Parent or a wholly owned subsidiary of Parent owns beneficially and of record all of the outstanding capital stock of Purchaser.

Section 4.3    Authority; Binding Nature of Agreement. Parent and Purchaser have the corporate power and authority to execute and deliver and perform their obligations under this Agreement; and the execution, delivery and performance by Parent and Purchaser of this Agreement has been duly authorized by all necessary action on the part of Parent and Purchaser and their respective boards of directors. This Agreement constitutes the legal, valid and binding obligation of Parent and Purchaser, and assuming due authorization, execution and delivery by the Company, is enforceable against them in accordance with its terms, subject to (a) laws of general application relating to bankruptcy, insolvency and the relief of debtors and (b) rules of law governing specific performance, injunctive relief and other equitable remedies.

Section 4.4    Non-Contravention; Consents. Assuming compliance with the applicable provisions of the HSR Act, and any applicable filing, notification or approval in any foreign jurisdiction required by Antitrust Laws, the execution and delivery of this Agreement by Parent and Purchaser, and the consummation of the Transactions, will not: (a) cause a violation of any of the provisions of the certificate of incorporation or bylaws or other organizational documents of Parent or Purchaser; (b) cause a violation by Parent or Purchaser of any Legal Requirement or order applicable to Parent or Purchaser, or to which they are subject; or (c) conflict with, result in a breach of, or constitute a default on the part of Parent or Purchaser under any Contract, except, in the case of clauses “(b)” and “(c)”, for such conflicts, violations, breaches or defaults as would not reasonably be expected to have a Parent Material Adverse Effect.

No national or subnational governments of a single foreign state have a “substantial interest” in Parent within the meaning of the Defense Production Act of 1950, including all implementing regulations thereof (the “DPA”). No vote of Parent’s stockholders is necessary to approve this Agreement or any of the Transactions.

Section 4.5    Disclosure. None of the Offer Documents will contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading. None of the information with respect to Parent or Purchaser supplied or to be supplied by or on behalf of Parent or Purchaser or any of their Subsidiaries specifically for inclusion or incorporation by reference in the Schedule 14D-9 will, at the time such document is filed with the SEC, at any time such document is amended or supplemented or at the time such document is first published, sent or given to the Company’s stockholders, contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading.

Section 4.6    Absence of Litigation. There is no Legal Proceeding pending and served or, to the knowledge of Parent, pending and not served or overtly threatened against Parent or Purchaser, except as would not and would not reasonably be expected to materially and

34

adversely affect Parent’s or Purchaser’s ability to consummate the Transactions. To the knowledge of Parent or Purchaser, as of the date of this Agreement, neither Parent nor Purchaser is subject to any continuing order of, consent decree, settlement agreement or similar written agreement with, or continuing investigation by, any Governmental Body, or any order, writ, judgment, injunction, decree, determination or award of any Governmental Body, except as would not and would not reasonably be expected to materially and adversely affect Parent’s or Purchaser’s ability to consummate the Transactions.

Section 4.7    Funds. Parent has, and will at the Closing have, cash resources in immediately available funds and in an amount sufficient to consummate the Transactions.

Section 4.8    Ownership of Company Common Stock. Neither Parent nor any of Parent’s Affiliates directly or indirectly owns, and at all times for the past three years, neither Parent nor any of Parent’s controlled Affiliates has owned, beneficially or otherwise, any shares of the Company’s capital stock or any securities, contracts or obligations convertible into or exercisable or exchangeable for shares of the Company’s capital stock. Neither Parent nor Purchaser has enacted or will enact a plan that complies with Rule 10b5-1 under the Exchange Act covering the purchase of any of the shares of the Company’s capital stock. As of the date hereof, neither Parent nor Purchaser is an “interested stockholder” of the Company under Section 203(c) of the DGCL.

Accordingly, Parent and Purchaser hereby acknowledge and agree that neither the Company nor any of its

35

Affiliates, stockholders, directors, officers, employees, consultants, agents, representatives or advisors, nor any other person, has made or is making any express or implied representation or warranty with respect to such estimates, projections, forecasts, forward-looking statements or business plans unless any such information is expressly addressed or included in a representation or warranty contained in this Agreement.

equity in any Person or by any other manner or engage in any other material transaction or take any other material action, if the entering into of an agreement relating to or the consummation of such acquisition, merger, consolidation or purchase or other transaction or action would reasonably be expected to (i) impose any material delay in the expiration or termination of any applicable waiting period or impose any material delay in the obtaining of, or increase the risk of not obtaining, any authorization, consent, clearance, approval or order of a Governmental Body necessary to consummate the Offer, the Merger and the other transactions contemplated by this Agreement, including any approvals and expiration of waiting periods pursuant to the HSR Act or any other applicable Legal Requirements, (ii) increase the risk of any Governmental Body entering, or increase the risk of not being able to remove or successfully challenge, any permanent, preliminary or temporary injunction or other order decree, decision, determination or judgment that would delay, restrain, prevent, enjoin or otherwise prohibit consummation of the Offer, the Merger and the other transactions contemplated by this Agreement or (iii) otherwise materially delay or impede the consummation of the Offer, the Merger and the other transactions contemplated by this Agreement ((i), (ii) and (iii) collectively, “Regulatory Hurdles”).

Section 6.3    Company Options.

(b)    Prior to the Offer Acceptance Time, the Company shall take all actions that may be necessary to terminate any repurchase rights of the Company with respect to any Restricted Shares then outstanding as of immediately prior to the Offer Acceptance Time.

(c)    As soon as reasonably practicable following the date of this Agreement and in any event prior to the Effective Time and not later than the day immediately prior to the date on which the first offering period that is regularly scheduled to commence under the ESPP after the date of this Agreement, the Company will take all necessary actions, including obtaining any necessary determinations or resolutions of the Company Board (or a committee thereof), if appropriate, and amending the terms of the ESPP as may be necessary or required under the ESPP and applicable Laws, to (i) provide that each individual participating in the Offering (as defined in the ESPP) in progress on the date of this Agreement (the “Final Offering”) will not be permitted to increase the percentage of his or her earnings (as defined in the Final Offering documents) pursuant to the ESPP from the individual’s applicable elected

47

percentage of earnings that was in effect when that Offering commenced, or make any non-payroll contributions to the ESPP on or following the date of this Agreement; (ii) ensure that, except for the Final Offering, no offering period under the ESPP will be authorized or commenced on or after the date of this Agreement; (iii) if the Closing will occur prior to the end of the Final Offering, provide each individual participating in the Final Offering with notice of the transactions contemplated by this Agreement prior to the Closing Date; (iv) cause the Final Offering to end on the date that is immediately prior to the Closing Date; (v) make any pro rata adjustments that may be necessary to reflect the shortened Purchase Period (as defined in the ESPP) of the Final Offering, but otherwise treat such shortened Purchase Period of the Final Offering as a fully effective and completed Purchase Period for all purposes pursuant to the ESPP; (vi) cause each ESPP participant’s accumulated contributions under the ESPP to be used to purchase shares of Company Common Stock in accordance with the ESPP as of the end of the Final Offering; (vii) provide that the applicable purchase price for Company Common Stock will not be decreased below the levels set forth in the ESPP as of the date of this Agreement; and (viii) ensure that no further rights are granted under the ESPP after the Effective Time.

Section 6.4    Employee Benefits. For a period of one year following the Effective Time, Parent shall provide, or cause to be provided, to each employee of the Company who is employed by the Company as of immediately prior to the Effective Time and who continues to be employed by the Surviving Corporation (or any Affiliate thereof) during such one year period (each, a “Continuing Employee”) a base salary (or base wages, as the case may be) and short-term cash incentive compensation opportunities, each of which is no less favorable than the base salary (or base wages, as the case may be) and short-term cash incentive compensation opportunities provided to such Continuing Employee immediately prior to the Effective Time, and broad-based employee benefits (excluding equity and equity-based awards, severance and change in control plans, programs, perquisites and arrangements) that are substantially comparable in the aggregate to the benefits (excluding equity and equity-based awards, severance and change in control plans, programs, perquisites and arrangements) provided to such Continuing Employee immediately prior to the Effective Time:

(a)    Each Continuing Employee shall be given service credit for purposes of (i) eligibility to participate and eligibility for vesting, and (ii), only under Parent’s and/or Surviving Corporation’s vacation, sick and/or PTO policies, levels of benefits, in each case under Parent’s and/or the Surviving Corporation’s employee benefit plans and arrangements to the extent such Continuing Employee is eligible to participate in such plans and arrangements and coverage under such plans and arrangements replaces coverage under a comparable Employee Plan in which such Continuing Employee participates immediately prior to the Closing Date, with respect to his or her length of service with the Company (and its predecessors) prior to the Closing Date, provided that the foregoing shall not result in the duplication of benefits under any such employee benefit plans and arrangements.

(b)    With respect to any accrued but unused personal, sick or vacation time to which any Continuing Employee is entitled pursuant to the personal, sick or vacation policies applicable to such Continuing Employee immediately prior to the Effective Time, Parent shall, or shall cause the Surviving Corporation to and instruct its Affiliates to, as applicable (and

48

without duplication of benefits), assume, as of the Effective Time, the liability for such accrued personal, sick or vacation time and allow such Continuing Employee to use such accrued personal, sick or vacation time in accordance with the practice and policies of the Company.

(c)    To the extent that service is relevant for eligibility, vesting or allowances under any health or welfare benefit plan of Parent and/or the Surviving Corporation, then Parent shall (i) use commercially reasonable efforts to waive all limitations as to pre-existing conditions, exclusions and waiting periods with respect to participation and coverage requirements applicable to the Continuing Employees, to the extent that such conditions, exclusions and waiting periods would not apply under a similar employee benefit plan in which such employees participated prior to the Effective Time and (ii) use commercially reasonable efforts to ensure that such health or welfare benefit plan shall, for purposes of eligibility, vesting, deductibles, co-payments and out-of-pocket maximums and allowances, credit Continuing Employees for service and amounts paid prior to the Effective Time with the Company (and its predecessors) to the same extent that such service and amounts paid was recognized prior to the Effective Time under the corresponding health or welfare benefit plan of the Company.

(d)    Effective as of no later than the day immediately preceding the Closing Date, if requested by Parent in writing at least ten (10) business days prior to the Closing Date, the Company shall cause the Principia Biopharma 401(k) Plan (the “401(k) Plan”) to be terminated. If Parent provides such written notice to the Company, the Company shall provide Parent with evidence that the 401(k) Plan has been terminated (effective as of no later than the day immediately preceding the Closing Date), and the Company shall have taken all steps necessary to terminate the 401(k) Plan as Parent may reasonably require.

(e)    The provisions of this Section 6.4 are solely for the benefit of the Parties to this Agreement, and no provision of this Section 6.4 is intended to, or shall, constitute the establishment or adoption of or an amendment to any employee benefit plan for purposes of ERISA or otherwise and no current or former employee or any other individual associated therewith shall be regarded for any purpose as a third party beneficiary of this Agreement or have the right to enforce the provisions hereof. Nothing in this Agreement shall confer upon any director, employee or service provider of the Company any right to continue in the employ or service of the Surviving Corporation, Parent or any subsidiary or affiliate thereof, or shall interfere with or restrict in any way the rights of the Surviving Corporation, Parent or any subsidiary or affiliate thereof to discharge or terminate the services of any director, employee or individual service provider of the Company at any time for any reason whatsoever, with or without cause.

Section 6.5    Indemnification of Officers and Directors.

(a)    All rights to indemnification, advancement of expenses and exculpation by the Company existing in favor of those Persons who are directors or officers of the Company as of the date of this Agreement or have been directors or officers of the Company in the past (the “Indemnified Persons”) for their acts and omissions occurring prior to the Effective Time, as provided in the certificate of incorporation and bylaws of the Company (as in effect as of the date of this Agreement) and as provided in the indemnification agreements between the Company and said Indemnified Persons (as set forth on Part 6.5(a) of the Company Disclosure

49

Schedule and in effect as of the date of this Agreement) in the forms made available by the Company to Parent or Parent’s Representatives prior to the date of this Agreement, shall survive the Merger and shall not be amended, repealed or otherwise modified in any manner that would adversely affect the rights thereunder of such Indemnified Persons, and shall be observed by the Surviving Corporation and its Subsidiaries to the fullest extent available under Delaware or other applicable Legal Requirements for a period of six years from the Effective Time, and any claim made pursuant to such rights within such six-year period shall continue to be subject to this Section 6.5(a) and the rights provided under this Section 6.5(a) until disposition of such claim.

(b)    From the Effective Time until the sixth anniversary of the date on which the Effective Time occurs, Parent and the Surviving Corporation (together with their successors and assigns, the “Indemnifying Parties”) shall, to the fullest extent the Company would have been, prior to the Effective Time, permitted under applicable Legal Requirements, indemnify and hold harmless each Indemnified Person in his or her capacity as an officer or director of the Company against all losses, claims, damages, liabilities, fees, expenses, judgments or fines incurred by such Indemnified Person as an officer or director of the Company in connection with any pending or threatened Legal Proceeding based on or arising out of, in whole or in part, the fact that such Indemnified Person is or was a director or officer of the Company at or prior to the Effective Time and pertaining to any and all matters pending, existing or occurring at or prior to the Effective Time, whether asserted or claimed prior to, at or after the Effective Time, including any such matter arising under any claim with respect to the Transactions. Without limiting the foregoing, from the Effective Time until the sixth anniversary of the date on which the Effective Time occurs, the Indemnifying Parties shall also, to the fullest extent permitted under applicable Legal Requirements, advance reasonable and documented out-of-pocket costs and expenses (including reasonable and documented attorneys’ fees) incurred by the Indemnified Persons in connection with matters for which such Indemnified Persons are eligible to be indemnified pursuant to this Section 6.5(b) within 15 days after receipt by Parent of a written request for such advance, subject to the execution by such Indemnified Persons of appropriate undertakings in favor of the Indemnifying Parties to repay such advanced costs and expenses if it is ultimately determined in a final and non-appealable judgment of a court of competent jurisdiction that such Indemnified Person is not entitled to be indemnified under this Section 6.5(b).

(c)    From the Effective Time until the sixth anniversary of the Effective Time, the Surviving Corporation shall, and Parent shall cause the Surviving Corporation to, maintain, in effect, the existing policy of directors’ and officers’ liability insurance maintained by the Company as of the date of this Agreement (an accurate and complete summary of which has been made available by the Company to Parent or Parent’s Representatives prior to the date of this Agreement) for the benefit of the Indemnified Persons who are currently covered by such existing policy with respect to their acts and omissions occurring prior to the Effective Time in their capacities as directors and officers of the Company (as applicable), on terms with respect to coverage, deductibles and amounts no less favorable than the existing policy (or at or prior to the Effective Time, Parent or the Company may (through a nationally recognized insurance broker approved by Parent (such approval not to be unreasonably withheld, delayed or conditioned)) purchase a six-year “tail” policy for the existing policy effective as of the Effective Time) and if such “tail policy” has been obtained, it shall be deemed to satisfy all obligations to obtain and/or maintain insurance pursuant to this Section 6.5(c); provided, however, that in no event shall the Surviving Corporation be required to expend in any one year an amount in excess of 300% of the

50

annual premium currently payable by the Company with respect to such current policy, it being understood that if the annual premiums payable for such insurance coverage exceeds such amount, Parent shall be obligated to cause the Surviving Corporation to obtain a policy with the greatest coverage available for a cost equal to such amount.

(d)    In the event Parent or the Surviving Corporation or any of their respective successors or assigns (i) consolidates with or merges into any other Person and shall not be the continuing or surviving corporation or Entity of such consolidation or merger or (ii) transfers all or substantially all of its properties and assets to any Person, then, and in each such case, Parent shall ensure that the successors and assigns of Parent or the Surviving Corporation, as the case may be, or at Parent’s option, Parent, shall assume the obligations set forth in this Section 6.5.

(e)    The provisions of this Section 6.5 shall survive the acceptance of Shares for payment pursuant to the Offer and the consummation of the Merger and are (i) intended to be for the benefit of, and shall be enforceable by, each of the Indemnified Persons and their successors, assigns and heirs and (ii) in addition to, and not in substitution for, any other rights to indemnification or contribution that any such Person may have by contract or otherwise. Unless required by applicable Legal Requirement, this Section 6.5 may not be amended, altered or repealed after the Offer Acceptance Time in such a manner as to adversely affect the rights of any Indemnified Person or any of their successors, assigns or heirs without the prior written consent of the affected Indemnified Person.

Section 6.6    Securityholder Litigation. The Company shall promptly notify Parent of any litigation against the Company and/or its directors relating to the Transactions. The Company shall control any Legal Proceeding brought by stockholders of the Company against the Company and/or its directors relating to the Transactions; provided that the Company shall give Parent the right to review and comment on all material filings or responses to be made by the Company in connection with such litigation, and the right to consult on the settlement with respect to such litigation, and the Company shall in good faith take such comments into account. No such settlement shall be agreed to without Parent’s prior written consent (such consent not to be unreasonably withheld, conditioned or delayed), except to the extent the settlement is fully covered by the Company’s insurance policies (other than any applicable deductible), but only if such settlement would not result in the imposition of any restriction on the business or operations of the Company.

Section 6.7    Additional Agreements. Without limitation or contravention of the provisions of Section 6.2, and subject to the terms and conditions of this Agreement, Parent and the Company shall use commercially reasonable efforts to take, or cause to be taken, all actions necessary to consummate the Offer and the Merger and make effective the other Transactions. Without limiting the generality of the foregoing, subject to the terms and conditions of this Agreement, each Party to this Agreement shall (i) make all filings (if any) and give all notices (if any) required to be made and given by such Party in connection with the Offer and the Merger and the other Transactions pursuant to any applicable Legal Requirements or Material Contract set forth on Schedule 6.7(a), (ii) use commercially reasonable efforts to obtain each Consent (if any) required to be obtained pursuant to any applicable Legal Requirement or Material Contract set forth on Schedule 6.7(b) by such Party in connection with the Transactions and (iii) use commercially reasonable efforts to lift any restraint, injunction or other legal bar to the Offer or

51

the Merger brought by any third Person against such Party. The Company shall promptly deliver to Parent a copy of each such filing made, each such notice given and each such Consent obtained by the Company during the Pre-Closing Period.

Notwithstanding the foregoing: (a) each Party may, without such consultation or consent, make any public statement in response to questions from the press, analysts, investors or those attending industry conferences, make internal announcements to employees and make disclosures in Company SEC Documents, so long as such statements are consistent with previous press releases, public disclosures or public statements made jointly by the parties (or individually, if approved by the other Party); (b) a Party may, without the prior consent of the other Party hereto but subject to giving advance notice to the other Party, issue any such press release or make any such public announcement or statement as may be required by any Legal Requirement; and (c) the Company need not consult with Parent in connection with such portion of any press release, public statement or filing to be issued or made pursuant to Section 5.3(e) or with respect to any Acquisition Proposal or Company Adverse Change Recommendation, and neither Party shall be required by this Section 6.8 to consult with or seek consent from the other Party relating to any dispute between the Parties relating to this Agreement.

(b)    The Company shall give prompt notice to Parent (and shall subsequently keep Parent informed on a current basis of any developments related to such notice) upon its becoming aware of the occurrence or existence of any fact, event or circumstance that is reasonably likely to result in any of the conditions set forth in Section 7 or Annex I not being able to be satisfied prior to the End Date. Parent shall give prompt notice to the Company (and shall subsequently keep the Company informed on a current basis of any developments related to such notice) upon its becoming aware of the occurrence or existence of any fact, event or circumstance that (i) has had or would reasonably be expected to have a Parent Material Adverse Effect or (ii) is reasonably likely to result in any of the conditions set forth in Section 7 not being able to be satisfied prior to the End Date.

55

(a)    Except as set forth in this Section 8.3, all fees and expenses incurred in connection with this Agreement and the Transactions shall be paid by the Party incurring such expenses, whether or not the Offer and Merger are consummated.

(b)    In the event that:

(i)    this Agreement is terminated by the Company pursuant to Section 8.1(e);

(ii)    this Agreement is terminated by Parent pursuant to Section 8.1(c); or

(iii)    (A) this Agreement is terminated pursuant to Section 8.1(d) (but in the case of a termination by the Company, only if at such time Parent would not be prohibited from terminating this Agreement pursuant to the proviso to Section 8.1(d)) or Section 8.1(f), (B) any Person shall have publicly disclosed a bona fide Acquisition Proposal after the date hereof and shall not have publicly withdrawn such Acquisition Proposal prior to (1) in the case of this Agreement being subsequently terminated pursuant to Section 8.1(d), the date that is four business days prior to the Expiration Date or (2) in the case of this Agreement being subsequently terminated pursuant to Section 8.1(f), the time of the breach or failure to perform giving rise to such termination and (C) within twelve (12) months of such termination the Company shall have consummated an Acquisition Proposal or entered into a definitive agreement with respect to an Acquisition Proposal (provided that for purposes of this clause (C) the references to “20% or more” in the definition of “Acquisition Proposal” shall be deemed to be references to “more than 50%”);

then, in any such event under clause “(i)”, “(ii)” or “(iii)” of this Section 8.3(b), the Company shall pay to Parent or its designee the Termination Fee by wire transfer of same day funds (x) in the case of Section 8.3(b)(i), on the date that the Specified Agreement is executed (or if the Specified Agreement is executed on a day that is not a business day, the next business day), (y) in the case of Section 8.3(b)(ii), within two business days after such termination or (z) in the case of Section 8.3(b)(iii), within two business days after the entering into the definitive agreement with respect to the Acquisition Proposal referred to in subclause (iii)(C) above; it being understood that in no event shall the Company be required to pay the Termination Fee on more than one occasion.

Except in the case of common law fraud or Willful Breach, in the event that Parent or its designee shall receive full payment pursuant to this Section 8.3(b), the receipt of the Termination Fee shall be deemed to be liquidated damages for any and all losses or damages suffered or incurred by Parent, Purchaser, any of their respective Affiliates or any other Person in connection with this Agreement (and the termination hereof), the Transactions (and the abandonment thereof) or any matter forming the basis for such termination, and none of Parent, Purchaser, any of their respective Affiliates (collectively, “Parent Related Parties”) or any other Person shall be entitled to bring or maintain any claim, action or proceeding against the Company or any of its Affiliates arising out of or in connection with this Agreement, any of the Transactions or any matters forming the basis for such termination (other than in the case of

56

common law fraud or Willful Breach); provided, however, that Parent may seek specific performance to cause the Company to consummate the Transactions in accordance with Section 9.5(b), but in no event shall Parent be entitled to both specific performance and the payment of the Termination Fee. Any Termination Fee paid to Parent pursuant to this Section 8.3(b) will be offset against any award for damages given in any final and non-appealable judgment of a court of competent jurisdiction to Parent pursuant to any claim based upon common law fraud or Willful Breach.

(c)    Parent’s right to receive payment from the Company of the Termination Fee pursuant to Section 8.3(b) and any payments pursuant to Section 8.3(d) shall be the sole and exclusive remedy of the Parent Related Parties against the Company and any of their respective former, current or future officers, directors, partners, stockholders, optionholders, managers, members or Affiliates (collectively, “Company Related Parties”) for any loss suffered as a result of the failure of the Offer or the Merger to be consummated or for a breach or failure to perform hereunder or otherwise, and upon payment of such amount(s), none of the Company Related Parties shall have any further liability or obligation relating to or arising out of this Agreement or the Transactions.

(d)    The Parties acknowledge that the agreements contained in this Section 8.3 are an integral part of the Transactions and that, without these agreements, the Parties would not enter into this Agreement; accordingly, if the Company fails to timely pay any amount due pursuant to this Section 8.3, and, in order to obtain the payment, Parent commences a Legal Proceeding which results in a judgment against the Company, the Company shall pay Parent its reasonable and documented costs and expenses (including reasonable and documented attorneys’ fees) in connection with such suit, together with interest on such amount at the prime rate as published in the Wall Street Journal in effect on the date such payment was required to be made through the date such payment was actually received.

Section 9.2    Waiver.

No Party shall be deemed to have waived any claim arising out of this Agreement, or any power, right, privilege or remedy under this Agreement, unless the waiver of such claim, power, right, privilege or remedy is expressly set forth in a written instrument duly executed and delivered on behalf of such Party; and any such waiver shall not be applicable or have any effect except in the specific instance in which it is given.

57

Section 9.3    No Survival of Representations and Warranties. None of the representations and warranties or covenants contained in this Agreement, the Company Disclosure Schedule or in any certificate or schedule or other document delivered pursuant to this Agreement shall survive the Merger, except for those covenants that by their terms survive the Effective Time, this Section 9 and the any applicable defined terms in Exhibit A shall survive the Effective Time.

Section 9.4    Entire Agreement; Counterparts. This Agreement and the other agreements, exhibits, annexes and schedules referred to herein constitute the entire agreement and supersede all prior agreements and understandings, both written and oral, among or between any of the Parties, with respect to the subject matter hereof and thereof; provided, however, that the Confidentiality Agreement shall not be superseded and shall remain in full force and effect; provided, further, that, if the Effective Time occurs, the Confidentiality Agreement shall automatically terminate and be of no further force and effect. This Agreement may be executed in several counterparts, each of which shall be deemed an original and all of which shall constitute one and the same instrument. The exchange of a fully executed Agreement (in counterparts or otherwise) by PDF shall be sufficient to bind the Parties to the terms and conditions of this Agreement.

Section 9.5    Applicable Legal Requirements; Jurisdiction; Specific Performance; Remedies.

(a)    This Agreement shall be governed by, and construed in accordance with, the laws of the State of Delaware, without giving effect to any laws, rules or provisions that would cause the application of the laws of any jurisdiction other than the State of Delaware. Subject to Section 9.5(c), in any action or proceeding arising out of or relating to this Agreement or any of the Transactions: (i) each of the Parties irrevocably and unconditionally consents and submits to the exclusive jurisdiction and venue of the Chancery Court of the State of Delaware and any state appellate court therefrom or, if such court lacks subject matter jurisdiction, the United States District Court sitting in New Castle County in the State of Delaware (it being agreed that the consents to jurisdiction and venue set forth in this Section 9.5(a) shall not constitute general consents to service of process in the State of Delaware and shall have no effect for any purpose except as provided in this paragraph and shall not be deemed to confer rights on any Person other than the Parties hereto); and (ii) each of the Parties irrevocably consents to service of process by first class certified mail, return receipt requested, postage prepaid, to the address at which such Party is to receive notice in accordance with Section 9.8. The Parties hereto agree that a final judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by applicable Legal Requirements; provided, however, that nothing in the foregoing shall restrict any Party’s rights to seek any post-judgment relief regarding, or any appeal from, such final trial court judgment.

(b)    The Parties agree that irreparable damage for which monetary damages, even if available, would not be an adequate remedy, would occur in the event that the Parties hereto do not perform their obligations under the provisions of this Agreement in accordance with its specified terms or otherwise breach such provisions. Subject to the following sentence, the Parties acknowledge and agree that (i) the Parties shall be entitled to an injunction or

58

injunctions, specific performance, or other non-monetary equitable relief, to prevent breaches of this Agreement and to enforce specifically the terms and provisions hereof in the courts described in Section 9.5(a) without proof of damages or otherwise, this being in addition to any other remedy to which they are entitled under this Agreement, (ii) the provisions set forth in Section 8.3: (x) are not intended to and do not adequately compensate for the harm that would result from a breach of this Agreement; and (y) shall not be construed to diminish or otherwise impair in any respect any Party’s right to specific performance except if Parent has been paid the Termination Fee, and (iii) the right of specific performance is an integral part of the Transactions and without that right, neither the Company nor Parent would have entered into this Agreement. Except if the Termination Fee has been paid pursuant to Section 8.3, each of the Parties hereto agrees that it will not oppose the granting of an injunction, specific performance and other equitable relief on the basis that the other Parties hereto have an adequate remedy at law or an award of specific performance is not an appropriate remedy for any reason at law or equity. The Parties hereto acknowledge and agree that any Party seeking an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement in accordance with this Section 9.5(b) shall not be required to provide any bond or other security in connection with any such order or injunction.

(c)    EACH OF THE PARTIES HERETO IRREVOCABLY WAIVES ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING BETWEEN THE PARTIES HERETO ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY.

Section 9.6    Assignability. This Agreement shall be binding upon, and shall be enforceable by and inure solely to the benefit of, the Parties hereto and their respective successors and permitted assigns; provided, however, that neither this Agreement nor any of the rights hereunder may be assigned without the prior written consent of the other Parties hereto, and any attempted assignment of this Agreement or any of such rights without such consent shall be void and of no effect; provided, further, however, that Parent or Purchaser may assign this Agreement to any of their Affiliates (provided that such assignment shall not impede or delay the consummation of the Transactions or otherwise impede the rights of the stockholders of the Company under this Agreement); provided that no such assignment or pledge permitted pursuant to this Section 9.6 shall relieve Parent of its obligations hereunder.

Section 9.7    No Third Party Beneficiaries. Nothing in this Agreement, express or implied, is intended to or shall confer upon any Person (other than the Parties hereto) any right, benefit or remedy of any nature whatsoever under or by reason of this Agreement; except for: (i) if the Offer Acceptance Time occurs (A) the right of the Company’s stockholders to receive the Offer Price or Merger Consideration, as applicable and (B) the right of the holders of Company Options to receive the Option Consideration, as applicable pursuant to Section 2.8; (ii) the provisions set forth in Section 6.5; and (iii) the limitations on liability of the Company Related Parties set forth in Section 8.3(c).

Section 9.8    Notices.

Section 9.9    Severability. Any term or provision of this Agreement that is invalid or unenforceable in any situation in any jurisdiction shall not affect the validity or enforceability of the remaining terms and provisions of this Agreement or the validity or enforceability of the offending term or provision in any other situation or in any other jurisdiction. If a final judgment of a court of competent jurisdiction declares that any term or provision of this Agreement is

60

invalid or unenforceable, the Parties hereto agree that the court making such determination shall have the power to limit such term or provision, to delete specific words or phrases or to replace such term or provision with a term or provision that is valid and enforceable and that comes closest to expressing the intention of the invalid or unenforceable term or provision, and this Agreement shall be valid and enforceable as so modified. In the event such court does not exercise the power granted to it in the prior sentence, the Parties hereto agree to replace such invalid or unenforceable term or provision with a valid and enforceable term or provision that will achieve, to the extent possible, the economic, business and other purposes of such invalid or unenforceable term or provision.

The mere inclusion of an item in the Company Disclosure Schedule as an exception to a representation or warranty or covenant shall not be deemed an admission that such item represents a material exception or material fact, event or circumstance or that such item is material or constitutes a Material Adverse Effect, and no reference to, or disclosure of, any item or other matter in the Company Disclosure Schedule shall necessarily imply that any other undisclosed matter or item having a greater value or significance is material.
