(i) less than zero, then Phase Forward shall be entitled to recoup in accordance with Section 13.4, against the Escrow Amount an amount in cash equal to such shortfall.

(ii) greater than zero, then Phase Forward shall pay to the Securityholder Representative for further distribution to the Waban

Securityholders an amount equal to such excess, such payment to be made within five (5) business days following such final determination.

(f) The Final Net Working Capital reflected on the Closing Balance Sheet and the Closing Schedule delivered to the Securityholder Representative shall be conclusive and binding upon the parties unless the Securityholder Representative, within 20 days from the date of receipt of the Closing Balance Sheet and the Closing Schedule, delivers a written objection to Phase Forward specifying in reasonable detail the basis for the objection, and a computation of the Final Net Working Capital asserted by the Securityholder Representative (the “Working Capital Objection”).

The Accounting Expert shall notify the parties in writing of its determination within 30 days following the receipt of the Working Capital Determination Materials, which determination shall be final and conclusive. No such determinations shall result in adjustments to any items not in dispute and no adjustments shall be greater than claimed in any dispute by the Securityholder Representative. In acting hereunder, the Accounting Expert shall act as experts and not as arbiters. Phase Forward shall be entitled to offset one-half of the fees and expenses of the Accounting Expert from the Escrow Amount.

(d) To the extent Phase Forward is required to make any payments to any Waban Securityholder pursuant to Sections 4.4(b) or 4.4(c), the Securityholder Representative will pay to Phase Forward the amount of such payment less the Appraisal Reduction Amount, which such Appraisal Reduction Amount shall be subject to the indemnification provisions of Section 13.

(e) Each of Phase Forward and the Surviving Corporation shall be entitled to deduct and withhold from the Merger Consideration otherwise payable pursuant to this Agreement to the Securityholder Representative or any holder of shares of Waban Common Stock or Waban Rights such amounts, if any, as it would be required to deduct and withhold with respect to the making of such payment under the Code or any provision of state, local or foreign Tax Law, provided, however, Phase Forward and the Surviving Corporation shall pay all amounts so deducted or withheld to the appropriate Tax Authority when due.

From and after the Effective Time, subject to the provisions of this Article 13, the Waban Securityholders shall, jointly and severally, indemnify the Phase Forward Indemnitees from, against, for and in respect of Losses paid, suffered or incurred by such Phase Forward Indemnitee(s), and resulting from, based upon, arising out of or in connection with: (i) a breach of any representation or warranty of Waban contained in any Purchase Document; (ii) a breach of any covenant or agreement of Waban contained in any Purchase Document; (iii) the Appraisal Reduction Amount (including all related Proceedings) or any other claims or Proceedings made or brought against Phase Forward, Waban or any other Phase Forward Indemnitee by a Waban Securityholder as a result of this Agreement or the Merger; (iv) Tax Claims (except to the extent that the liability for any Tax included in such Tax Claim was taken into account as a liability in the Final Net Working Capital); (v) any indemnification obligation to reimburse or advance payment for expenses to the Indemnified Directors/Officers for actions taken by them prior to the Effective Time (to the extent not covered by insurance); (vi) Benefits Claims (except to the extent that the liability for any such Benefits Claim was taken into account as a liability in the Final Net Working Capital); (vii) Transaction Fees (to the extent not reflected in the calculation of the Closing Date Consideration or the calculation of the Final Net Working Capital); (viii) Indebtedness of Waban that existed prior to or at the Effective Time (to the extent not reflected in the calculation of the Closing Date Consideration or the calculation of the Final Net Working Capital); (ix) any Net Working Capital shortfall determined pursuant to Section 4.6(e)(i), (x) those matters described on Exhibit 13.1, and (xi) those matters described in Section 14.4 with respect to the allocation of the Merger Consideration by the Securityholder Representative to the Waban Securityholders. “Phase Forward Indemnitees” means Phase Forward and its Affiliates (including from and after the Effective Time, Waban), and their respective agents, representatives, employees, officers and directors.

13.2 Procedures. A Phase Forward Indemnitee claiming indemnification under this Agreement (except for a claim under clause (ix) of Section 13.1, which shall be governed by the procedure set forth in Section 4.6(e)(i)) shall notify the Securityholder Representative, specifying the basis on which indemnification is sought.

(a) If the indemnification claim involves a matter other than a third party claim, the Securityholder Representative shall have 20 days after delivery of notice of the claim to object by delivery of notice of such objection to Phase Forward, specifying the basis for such objection. Failure to timely object constitutes final and binding acceptance of the indemnification claim by the Securityholder Representative. If an objection is timely made, and if Phase Forward and Securityholder Representative do not resolve such objection pursuant to a written agreement executed by Phase Forward and the Securityholder Representative within 30 days after such objection is delivered to Phase Forward, such indemnification claim shall be resolved by arbitration in accordance with the provisions of Section 15.10.

(b) If an indemnification claim involves a third party claim, the Phase Forward Indemnitee shall: (i) promptly notify the Securityholder Representative of material information concerning the third party claim known to the Phase Forward Indemnitee, provided that failure to so notify the Securityholder Representative will only relieve the indemnification obligation if and to the extent such failure results in material prejudice with respect to such third party claim; and (ii) give the Securityholder Representative full opportunity to control the defense of such third party claim (using counsel reasonably acceptable to Phase Forward, which acceptance shall not be unreasonably withheld or delayed), including any settlement or compromise thereof; provided that the Phase Forward Indemnitee can participate in any proceeding to defend such third party claim, represented by counsel of its choosing, at its cost and expense; and provided further that Phase Forward can elect to control the defense of a third party claim for which any Phase Forward Indemnitee seeks indemnification, including any settlement or compromise thereof, if the claim involves an issue or matter which could have an adverse effect on the business, operations, Assets, affairs or prospects of Waban, any of its Subsidiaries or any Phase Forward Indemnitee (including administration of Tax Returns and responsibilities of Waban, or any of its Subsidiaries or any Phase Forward Indemnitee under Laws pertaining to Taxes). If, after notice thereof, the Securityholder Representative fails to promptly assume the defense of a third party claim for which indemnification is claimed hereunder, or, after having assumed defense of such claim, fails to diligently continue such defense, the Phase Forward Indemnitee can assume the defense thereof, including any settlement or compromise thereof, and shall be indemnified for the cost and expense of such defense; provided, however, that no Phase Forward Indemnitee may settle or compromise any such claim without the consent of the Securityholder Representative, which shall not be unreasonably withheld or delayed. Neither Waban (or any of its Subsidiaries) nor any Phase Forward Indemnitee (or its Assets) may be bound by any compromise or settlement of a third party claim without Phase Forward’s consent, not to be unreasonably withheld or delayed, unless (i) the sole relief is monetary damages for which the Phase Forward Indemnitees shall be fully indemnified, and (ii) there is no finding or admission of any violation of Law or rights of any Person and no effect on other claims that may be made against Waban (or any of its Subsidiaries) or any Phase Forward Indemnitee.

13.3 Limitation of Liability.

(a) In no event shall the Phase Forward Indemnitees be entitled to indemnification under Section 13.1 for Losses suffered or incurred by the Phase Forward Indemnitees in excess of an amount equal to thirty percent (30%) of the Base Consideration (“Maximum Amount”), except for Losses arising out of or related to matters listed on Exhibit 13.1, breaches of the representations, warranties or covenants contained in Sections 7.1, 7.18 or 8.7, any Net Working Capital shortfall determined pursuant to Section 4.6(e)(i), or as a result of fraud, intentional misrepresentation or intentional breach of a representation or warranty (collectively, “No Limit Losses”).

(b) No indemnification shall be payable for any Loss incurred by a Phase Forward Indemnitee to the extent that the amount of such Loss was included as a liability or reserve in the calculation of the Final Net Working Capital; provided, however, that nothing herein is intended to prevent a Phase Forward Indemnitee from seeking indemnification for any such Loss to the extent that the amount of such Loss exceeds the amount included as a liability or reserve in the calculation of the Final Net Working Capital.

(c) Except as set forth below, any claim by a Phase Forward Indemnitee for indemnification pursuant to Section 13.1 of this Agreement shall be required to be made by delivering notice to Securityholder Representative no later than the expiration of eighteen (18) months after the Closing Date. Notwithstanding the foregoing, (i) any claim for indemnification resulting from or arising out of any inaccuracy in or breach of any representation or warranty in Section 7.1 may be made at any time; and (ii) any claim for indemnification based upon, resulting from or arising out of (A) any inaccuracy in or breach of any representation or warranty made in Section 7.18 or Section 1(e) of Exhibit 7.15, (B) any inaccuracy in or breach of any covenant made in Section 8.7, or (C) any matter listed on Exhibit 13.1, may be made at any time prior to 3 months following the expiration of the applicable statute of limitations (including valid extensions thereof).

(d) Except for claims for indemnification for (i) any inaccuracy in or breach of (A) any representation or warranty made in Section 7.1(d), Section 7.1(e) or Section 7.18 or (B) any covenant made in Section 8.7, (ii) any Indebtedness of Waban that existed prior to or at the Effective Time (to the extent not reflected in the calculation of the Closing Date Consideration or the calculation of the Final Net Working Capital), (iii) any Transaction Fees (to the extent not reflected in the calculation of the Closing Date Consideration or the calculation of the Final Net Working Capital), (iv) any Losses arising out of matters set forth on Exhibit 13.1, or (v) any Net Working Capital shortfall determined pursuant to Section 4.6(e)(i), Phase Forward Indemnitees shall not be entitled to indemnification until the aggregate amount of all of Phase Forward Indemnitees’ claims for indemnification exceeds the Indemnification Threshold, in which case Phase Forward Indemnitees shall be entitled to indemnification only for amounts in excess of the Indemnification Threshold.

(e) Any claims for indemnification under this Article 13 shall be net of the amount of any recoveries paid under any insurance policy or “pass-through” warranty coverage from a manufacturer or other third party to Phase Forward, the Surviving Corporation, Waban or any of their Affiliates in connection with the circumstances that give rise to the claim for indemnification. Phase Forward shall, and shall cause the Surviving Corporation to, file claims and otherwise take all necessary

and appropriate action to recover any such recovery which may be available under such insurance policies or warranty coverage.

(f) No Non-Founder Securityholder shall be liable under this Article 13 for any amount in excess of such Non-Founder Securityholder’s Pro Rata Share of the Maximum Amount. Except for claims for indemnification for No Limit Losses, no Founder Securityholder shall be liable under this Article 13 for any amount in excess of such Founder Securityholder’s Pro Rata Share of the Maximum Amount.

13.4 Set-Off; Escrow Amount Administration. Phase Forward may recoup from the Escrow Amount the amount (as finally determined in accordance with this Agreement) of any indemnification claim of Phase Forward or any Phase Forward Indemnitees arising under or in connection with this Agreement for any Losses. The Escrow Agreement shall provide that the Escrow Agent shall pay any portion of the Escrow Amount remaining after any recoupment by any Phase Forward Indemnitee from the Escrow Amount in accordance with the terms of this Agreement and the Escrow Agreement to the Securityholder Representative (for further payment to the Waban Securityholders in accordance with Sections 4.2 and 4.3) within 20 days after the date that is 18 months after the Closing Date (the “Escrow Payment Date”), less an amount equal to the sum of the amount of any then pending indemnification claims, plus the estimated amount (reasonably determined by Phase Forward in good faith) of the other Losses that Phase Forward reasonably expects to incur specifically related to such pending indemnification claims prior to resolution of such pending claims. If all or a portion of the Escrow Amount otherwise payable on the Escrow Payment Date is held back (such amount, the “Deferred Escrow”) for pending claims, and in the event that after resolution of such pending claims, the amount of the Deferred Escrow exceeds the Losses recovered pursuant to such claims, the Escrow Agent shall, within twenty (20) days after resolution of such claims, pay to the Securityholder Representative the remaining portion of the Deferred Escrow, for further payment to the Waban Securityholders in accordance with Sections 4.2 and 4.3. Notwithstanding the foregoing, in no event shall the Escrow Amount be deemed to be the sole source of recovery of all Losses.

13.5 Indemnification of Waban Securityholders and the Securityholder Representative.

(a) From and after the Effective Time, subject to the provisions of this Article 13, the Waban Securityholders, the Securityholder Representative and their respective officers, directors, employees and agents (collectively, the “Waban Indemnitees”) shall be entitled to indemnification from, against, for and in respect of Losses paid, suffered or incurred by such Waban Indemnitee(s), and resulting from, based upon, arising out of or in connection with: (a) a breach of any representation or warranty of Phase Forward or Sub contained in any Purchase Document, or (b) a breach of any covenant or agreement of Phase Forward or Sub contained in any Purchase Document. Phase Forward does not make and shall not be deemed to have made, nor is any Waban Indemnitee relying upon, any representation, warranty or covenant other than those representations, warranties and covenants which are expressly set forth in this Agreement.

(b) Except as set forth below, any claim by a Waban Indemnitee for indemnification pursuant to this Section 13.5 shall be required to be made by delivering

notice to Phase Forward no later than the expiration of eighteen (18) months after the Closing Date. Notwithstanding the foregoing, any claim for indemnification resulting from or arising out of a breach of a covenant contained in Section 8.7 may be made at any time prior to 3 months following the expiration of the applicable statute of limitations (including valid extensions thereof).

(c) Except for claims for indemnification with respect to (i) a failure to pay any portion of the Merger Consideration or the amounts set forth in Section 11.2 when due or (ii) a breach of a covenant contained in Section 8.7, Waban Indemnitees shall not be entitled to indemnification until the aggregate amount of all of Waban Indemnitees’ claims for indemnification exceeds the Indemnification Threshold, and thereafter Waban Indemnitees shall be entitled to indemnification only for amounts in excess of the Indemnification Threshold.

(d) Except for claims for indemnification with respect to (i) a failure to pay any portion of the Merger Consideration or the amounts set forth in Section 11.2 when due or (ii) a breach of any covenant contained in Section 8.7, the maximum indemnification amount to which Waban Indemnitees may be entitled under this Agreement shall be an amount equal to an amount equal to the Maximum Amount.

13.6 Survival of Representations and Warranties. All representations and warranties set forth in this Agreement shall survive consummation of the Merger and the other transactions contemplated by this Agreement and shall continue in full force and effect for a period of eighteen (18) months after the Closing Date; provided, however, that the representations and warranties contained in Section 7.1 shall survive indefinitely, and the representations and warranties contained in Section 7.18 shall survive for 3 months following the applicable statute of limitations period. All covenants set forth in this Agreement shall survive consummation of the Merger and the other transactions contemplated by this Agreement and shall continue in full force and effect until performed in accordance with their terms.

13.7 Characterization of Indemnity Payments. Any indemnification payments made shall be treated as an adjustment to the Merger Consideration unless otherwise required by Law.

13.8 Sole Remedy. Except in the case of fraud, each Party acknowledges and agrees that from and after the Closing, the remedies provided for in this Article 13 shall be such Party’s sole and exclusive remedy with respect to any Loss arising out of any breach or claim relating to this Agreement or arising in connection herewith. Notwithstanding the foregoing, nothing contained in this Agreement shall limit a Party’s right to pursue equitable remedies, including injunctive relief and specific performance .

ARTICLE 14

SECURITYHOLDER REPRESENTATIVE

14.1 Appointment; Authority; Expenses.

(a) Waban hereby designates the Securityholder Representative to execute any and all instruments or other documents on behalf of Waban or the Waban Securityholders, and to do any and all other acts or things on behalf of Waban or the Waban Securityholders, which the Securityholder Representative may deem necessary

or advisable, or which may be required pursuant to this Agreement or otherwise, in connection with the consummation of the transactions contemplated hereby and the performance of all obligations hereunder before, at or following the Closing. Without limiting the generality of the foregoing, the Securityholder Representative shall have the full and exclusive authority to (i) agree with Phase Forward with respect to any matter or thing required or deemed necessary by the Securityholder Representative in connection with the provisions of this Agreement calling for the agreement of Waban or the Waban Securityholders, give and receive notices on behalf of Waban and the Waban Securityholders, and act on behalf of Waban and the Waban Securityholders in connection with any matter as to which Waban or the Waban Securityholders are or may be obligated under this Agreement or the Escrow Agreement, all in the absolute discretion of the Securityholder Representative, (ii) in general, do all things and perform all acts, including without limitation executing and delivering all agreements, certificates, receipts, consents, elections, instructions, and other instruments or documents contemplated by, or deemed by the Securityholder Representative to be necessary or advisable in connection with, this Agreement, and (iii) take all actions necessary or desirable in connection with the defense or settlement of any indemnification claims pursuant to Article 13 and performance of obligations of Waban, the Waban Securityholders or the Securityholder Representative, including to withhold the Securityholder Holdback and any other funds for the satisfaction of expenses or other liabilities or obligations or to withhold funds for potential indemnification claims made hereunder. Any fees and expenses of the Securityholder Representative (including but not limited to legal fees and expenses) shall be borne exclusively by the Waban Securityholders.

(b) The Waban Securityholders shall cooperate with the Securityholder Representative and any accountants, attorneys or other agents whom he may retain to assist in carrying out his duties hereunder. All decisions by the Securityholder Representative shall be binding upon all the Waban Securityholders, and no Waban Securityholder shall have the right to object, dissent, protest or otherwise contest the same. The Securityholder Representative may communicate with any Waban Securityholder or any other Person concerning his responsibilities hereunder, but is not required to do so. The Securityholder Representative has a duty to serve in good faith the interests of the Waban Securityholders and to perform his designated role under this Agreement, but the Securityholder Representative shall have no financial liability whatsoever to any Person relating to its service hereunder (including any action taken or omitted to be taken), except that he shall be liable for harm which he directly causes by an act of willful misconduct.

(c) The Waban Securityholders shall indemnify and hold harmless the Securityholder Representative from and against any loss, expense (including reasonable attorney’s fees) or other liability arising out of its service as the Securityholder Representative under this Agreement, other than for harm directly caused by an act of willful misconduct. In acting hereunder, the Securityholder Representative may rely upon, and shall be protected in acting or refraining from acting upon, advice or an opinion of counsel, a certificate of auditors or any other certificate, statement, instrument, opinion, report, notice, request, consent, order, arbitrator’s award, appraisal, bond or other paper or document reasonably believed by him to be genuine and to have been signed or presented by the proper party or parties. The Securityholder Representative may consult with counsel, and any advice of such counsel shall be full and complete authorization and protection in respect to any action taken or suffered or

omitted by him in such capacity in good faith and in accordance with such opinion of counsel. The Securityholder Representative may perform his duties either directly or by or through his agents or attorneys, and the Securityholder Representative shall not be responsible to the other Waban Securityholders for any misconduct or negligence on the part of any agent or attorney appointed with reasonable care by him.

14.2 Acceptance. By executing and delivering this Agreement, the Person who is appointed as the Securityholder Representative and is executing this Agreement in such capacity hereby (1) accepts his/her appointment and authorization to act as Securityholder Representative as in accordance with the terms of this Agreement and (2) agrees to perform its obligations under this Agreement.

14.3 Successor. The Securityholder Representative may resign upon 30 days prior notice to Phase Forward and the Waban Securityholders, provided that such resignation is not effective until appointment of a successor. In the event of a notice of proposed resignation of the Securityholder Representative, the Waban Securityholders (or their successors or assigns) shall elect a replacement Securityholder Representative by a vote of the majority of the Pro Rata Shares of the Waban Securityholders and shall promptly notify Phase Forward thereof. Any successor so elected or selected shall have all of the power, authority, rights and privileges conferred upon the original Securityholder Representative, and the term “Securityholder Representative” shall be deemed to include any and all such successors.

14.4 Allocation to the Waban Securityholders of the Merger Consideration. The payment by Phase Forward of the Merger Consideration into the Securityholder Account shall constitute payment by Phase Forward to each Waban Securityholder and satisfaction of Phase Forward’s obligation to pay such amount hereunder. After such payment by Phase Forward, the Securityholder Representative shall be solely responsible for allocating and distributing to each Waban Securityholder such Waban Securityholder’s Pro Rata Share of the Merger Consideration from the Shareholder Account. The Merger Consideration and any collective obligations of the Waban Securityholders, including, without limitation, payment of Transaction Fees and liability for any indemnification claims hereunder, shall be allocated among the Waban Securityholders in accordance with the Merger Consideration Spreadsheet (which has been prepared by, and is the sole responsibility of, Waban). The portion of the Merger Consideration allocated to each Waban Securityholder (net of obligations and any reserves or holdbacks for indemnification obligations or otherwise established pursuant to this Agreement, the Escrow Agreement or by the Securityholder Representative in its sole discretion) shall be paid and distributed to such Waban Securityholder by means of check or by wire transfer of immediately available funds to an account designated by such Waban Securityholder to the Securityholder Representative prior to, on, or after the Closing. At the Closing, the Securityholder Representative may withhold from the proceeds otherwise distributable to each Waban Securityholder hereunder, and pay, such Waban Securityholder’s pro-rata portion of any Transaction Fees incurred by or on behalf of Waban or the Waban Securityholders in connection with the transactions contemplated hereby. Nothing in this Section 14.4 is intended or shall be construed to confer on any Waban Securityholder any rights against Phase Forward in respect of the portion of the Merger Consideration allocated to such Waban Securityholder or the net proceeds received after delivery of same into the Shareholder Account.

14.5 Reliance. Phase Forward and the Phase Forward Indemnitees may rely conclusively on all notices received from, agreements and determinations made by, documents executed and delivered by, or other actions or omissions of the Securityholder Representative.

Neither failure nor delay by any party in exercising any right or remedy, and no single or partial exercise of any right or remedy, precludes further exercise of that right or remedy or exercise of any other right or remedy.

invalid, illegal, or unenforceable in any respect, such invalidity, illegality, or unenforceability shall not affect any other provisions of this Agreement, and this Agreement shall be construed as if such invalid, illegal, or unenforceable provision(s) are not contained herein unless their deletion would result in such a material change as to cause completion of transactions contemplated hereby to be unreasonable.
