The shares of Common Stock of Parent issued in exchange for such shares of Company Restricted Stock shall also be unvested and subject to the same repurchase option, risk of forfeiture or other condition, and the certificate representing such shares of Parent Common Stock may accordingly (A) be held in escrow by Parent until such shares are no longer subject to such repurchase option, risk of forfeiture or other condition or (B) be marked with appropriate legends in the discretion of Parent while such shares are subject to such repurchase option, risk of forfeiture or other condition.

Each stock certificate of Merger Sub evidencing ownership of any such shares of Common Stock of Merger Sub shall, as of the Effective Time, evidence ownership of such shares of Common Stock of the Surviving Corporation. (j) Adjustments to Option Exchange Ratio.

(b) Notwithstanding the provisions of Section 1.7(a) above, if any holder of shares of Company Capital Stock who is otherwise entitled to exercise dissenters' rights under Delaware Law shall effectively withdraw or lose (through failure to perfect or otherwise) such dissenters' rights, then, as of the later of the Effective Time and the occurrence of such event, such holder's shares shall automatically be converted into and represent only the right to receive the Merger Consideration pursuant to Section 1.6 hereof, without interest on the payment and subject to the provisions of Section 1.8 and Article VII hereof, upon surrender of the certificate representing such shares. (c) The Company shall give Parent (i) prompt notice of any written demands for the exercise of dissenters' rights in respect of any shares of Company Capital Stock, withdrawals of such demands, and any other instruments served pursuant to Delaware Law (including without limitation instruments concerning appraisal or dissenters' rights) and received by the Company and (ii) the opportunity to participate in all negotiations and proceedings with respect to such demands. The Company shall not, except with the prior written consent of Parent, voluntarily make any payment with respect to any demands for the exercise of dissenters' rights in respect of any shares of Company Capital Stock or offer to settle or settle any such demands. Notwithstanding the foregoing, to the extent that Parent or the Company (i) makes any payment or payments in respect of any Dissenting Shares in excess of the consideration that otherwise would have been payable in respect of such shares in accordance with this Agreement or (ii) incurs any other costs or expenses in respect of any Dissenting Shares (excluding payments for such shares) (together "Dissenting Share Payments"), Parent shall be entitled to recover under the terms of Article VII hereof the amount of such Dissenting Share Payments. 1.8 Exchange Procedures; Surrender of Certificates. ---------------------------------------------- (a) Exchange Agent. Computershare Trust Company (or such agent as Parent -------------- shall reasonably appoint) shall serve as exchange agent (the "Exchange Agent") in the Merger. (b) Parent to Deposit Escrow Amount. Promptly after the Effective Time, ------------------------------- Parent shall make available to the Exchange Agent for exchange in accordance with this Article I, the Merger Consideration payable pursuant to Section 1.6 hereof; provided, however, that on behalf of the Indemnifying Stockholders (as defined in Section 7.2(a) hereof), Parent shall deposit into an escrow account the Escrow Amount. The portion of the Escrow Amount contributed on behalf of each holder of Company Capital Stock shall be determined with reference to each such holder's Pro Rata Escrow Basis. (c) Exchange Procedures. As soon as practicable after the Effective Time ------------------- (but in any event within ten business days following the Effective Time), Parent shall cause the Exchange Agent to mail to each holder of record of a certificate or certificates (the "Certificates") which immediately prior to the Effective Time represented outstanding shares of Company Capital Stock and which shares were converted into the right to receive the applicable consideration set forth in Section 1.6 hereof, (i) a letter of transmittal (which shall be in customary form and shall specify that delivery shall be effected, and risk of loss and title to the Certificates shall pass, only upon delivery of the Certificates to the Exchange Agent) and (ii) instructions for use in effecting the surrender of -8-

the Certificates in exchange for the applicable consideration set forth in Section 1.6. Upon surrender of a Certificate for cancellation to the Exchange Agent, together with such letter of transmittal, duly completed and validly executed in accordance with the instructions thereto, the holder of such Certificate shall be entitled to receive in exchange therefor such holder's portion of the Merger Consideration as set forth in Section 1.6 hereof less the portion of the Escrow Amount contributed on behalf of such holder and the Certificate so surrendered shall forthwith be canceled. As soon as practicable after the Effective Time, and subject to and in accordance with the provisions of Article VII hereof, Parent shall deposit the Escrow Amount with the Escrow Agent (as defined in Article VII hereof). The Escrow Amount so deposited with the Escrow Agent shall be available to compensate Parent as provided in Article VII hereof.

The covenants and agreements set forth in this Agreement and any ancillary document hereto that are to be performed following the Closing Date shall survive the Closing and continue in full force and effect until such covenants and agreements are performed in accordance with the terms of this Agreement and the applicable ancillary document. The representations and warranties of Parent and Merger Sub contained in this Agreement, or in any instrument delivered pursuant to this Agreement, shall terminate at the Closing. 7.2 Escrow Arrangements. ------------------- (a) Escrow Fund. At the Effective Time the holders of Company Capital ----------- Stock entitled to receive Merger Consideration pursuant to Section 1.6 hereof (the "Indemnifying Stockholders") will not receive the Escrow Amount but such stockholders will be deemed to have consented to the deposit with the Escrow Agent (as defined below) of the Escrow Amount without any act required on the part of any such stockholder. Instead, as soon as practicable after the Effective Time, the Escrow Amount, without any act required on the part of any stockholder, will be deposited by Parent with an escrow agent acceptable to Parent and the Stockholder Representative as Escrow Agent (the "Escrow Agent"), such deposit to constitute an escrow fund (the "Escrow Fund") to be governed by the terms set forth herein and at Parent's cost and expense. The portion of the Escrow Amount contributed on behalf of each holder of Company Capital Stock shall be determined with reference to each such stockholder's Pro Rata Escrow Basis. The Escrow Amount shall be contributed entirely out of the Merger Consideration payable upon the Merger in respect of -48-

the Company Capital Stock. The Escrow Fund is available to compensate Parent and its officers, directors and affiliates, including the Surviving Corporation (each, an "Indemnified Party" and collectively, the "Indemnified Parties") for any claims, losses, liabilities, damages, deficiencies, costs and expenses, including reasonable attorneys' fees and expenses, and expenses of investigation and defenses (hereinafter individually a "Loss" and collectively "Losses") paid, incurred, accrued or sustained by the Indemnified Parties, or any of them, directly or indirectly as a result of (i) any inaccuracy or breach of a representation or warranty of the Company contained in Article II herein as of the date of this Agreement or as of the Closing Date, as though then made (except to the extent that such representation or warranty speaks as of an earlier date), (ii) any failure by the Company to perform or comply with any covenant contained in this Agreement, (iii) any Dissenting Share Payments, (iv) any claim made by any person that such person is or was entitled (by contract or otherwise) to receive any amount or property in such person's capacity (or asserted capacity) as a holder of equity interests in the Company or contingent equity interests or as a beneficiary of any rights in excess of the consideration set forth in this Agreement by virtue of or as a result of the Merger, other than any claim described in clause (iii) above, (v) any claims made by foreign employees of the Company or any of its subsidiaries whether or not disclosed on the Disclosure Schedule, (vi) any claims made by Parametric Technology Corporation or its subsidiaries relating to the Company Intellectual Property, including, without limitation, any claims related to trade secret misappropriation, whether or not disclosed on the Disclosure Schedule, (vii) the Acceleration or (viii) the Cash Dividend; provided, however, that to the extent that a specific Liability (as defined in Section 2.7 hereof) is used to reduce the amount of the Cash Dividend (as calculated pursuant to Schedule 5.21 hereof), such Liability shall not be considered a Loss for purposes of this Article VII. Parent and the Company each acknowledge that such Losses, if any, would relate to unresolved contingencies existing at the Effective Time, which if resolved at the Effective Time would have led to a reduction in the aggregate Merger consideration. Nothing herein shall limit the liability of the Company for any breach of any representation, warranty or covenant if the Merger does not close. No Indemnified Party may recover any Losses unless and until one or more Officer's Certificates identifying a Loss or Losses in excess of $100,000 in the aggregate (the "Threshold Amount") has or have been delivered to the Escrow Agent as provided in Section 7.2(d) hereof, in which case such Indemnified Party -------------- shall be entitled to recover all Losses (including the Threshold Amount) so identified to the extent then available in the Escrow Fund. Notwithstanding the foregoing, Parent shall be entitled to recover for, and the Threshold Amount shall not apply as a threshold to, any and all claims or payments made with respect to (i) all Losses incurred pursuant to clauses (iii), (iv), (v) or (vi) of this Section 7.2(a), or (ii) fraud, intentional misrepresentation or willful misconduct. (b) Escrow Period; Distribution upon Termination of Escrow Periods. -------------------------------------------------------------- Subject to the following requirements, the Escrow Fund shall be in existence immediately following the Effective Time and shall terminate at 5:00 p.m., (California Time) on the Expiration Date (the "Escrow Period"); provided that the Escrow Period shall not terminate with respect to such amount (or some portion thereof), that is necessary in the reasonable judgment of Parent (subject to reduction as may be determined by arbitration of the matter as provided in Section 7.2(f) hereof in the event of the objection of the Stockholder Representative (as defined in Section 7.2(h) hereof) in -49-

the manner provided in Section 7.2(e) hereof) to satisfy any unsatisfied claims concerning facts and circumstances existing prior to the termination of such Escrow Period and to the extent specified in any Officer's Certificate (as defined below) delivered to the Escrow Agent prior to termination of such Escrow Period. As soon as all such claims have been resolved, the Escrow Agent shall transfer to the stockholders of the Company, pursuant to written instructions by Parent, the remaining portion of the Escrow Fund, if any, not required to satisfy such claims. Notwithstanding the foregoing, on the third business day following the date that is twelve months from the Closing Date, Parent shall instruct the Escrow Agent in writing to distribute 50% of the Escrow Amount remaining (and not subject to any unsatisfied claims under any Officer's Certificate(s) delivered to the Escrow Agent prior to the date of the Early Release) in the Escrow Fund to the stockholders (the "Early Release"); provided, however, that there shall be no Early Release if an Indemnified Party(ies) has previously submitted an Officer's Certificate(s) claiming an aggregate of $5,000,000 or more in Losses. Deliveries of Escrow Amounts to the stockholders of the Company pursuant to this Section 7.2(b) shall be made with reference to each stockholder's Pro Rata Escrow Basis. (c) Protection of Escrow Fund. The Escrow Agent shall hold and ------------------------- safeguard the Escrow Fund during the Escrow Period, shall treat such fund as a trust fund in accordance with the terms of this Agreement and shall hold and dispose of the Escrow Fund only in accordance with the terms hereof. All income earned on the cash in the Escrow Fund, if any, shall become part of, and be held as an additional portion of the Escrow Fund in proportion to each applicable stockholder's Pro Rata Escrow Basis, subject to the tax distribution authorized below. It is expressly agreed and understood that the Escrow Fund shall, until distributed pursuant to the terms of this Agreement or the Escrow Agreement, constitute assets of the Parent for tax purposes, provided, however, that the Escrow Agent shall not distribute any amounts from the Escrow Fund except as expressly provided in this Agreement or the Escrow Agreement or pursuant to any final and nonappealable order of a court of competent jurisdiction with respect to payment. Accordingly, for tax purposes, the assets and all earnings on the assets shall be considered owned by the Parent until distributed pursuant to the terms of this Agreement or the Escrow Agreement, and reported as such for all tax reporting purposes. Interest shall accrue on Parent's obligation to Company stockholders under the Escrow Fund arrangement at a rate equal to the rate at which interest is earned on the amounts in escrow. Parent will report such accrued interest to the Company stockholders as required by income tax reporting rules (including the original issue discount rules). The Escrow Agent is hereby directed to pay to the Company stockholders out of the Escrow Fund, as soon as reasonably practicable following the reporting of such accrued interest to such Company stockholders, a tax distribution equal to 40% of the amounts reported to Company stockholders. Within 30 days after the Closing Date, the Stockholder Representative shall deliver to Parent a properly executed, valid IRS Form W-8 or W-9 and such other tax reporting documents that the Parent may reasonably request, for each Company stockholder. (d) Claims Upon Escrow Fund. Subject to Section 7.2(e) hereof, upon ----------------------- receipt by the Escrow Agent at any time on or before the last day of the Escrow Period of a certificate signed by any officer of Parent (an "Officer's Certificate"): (A) stating that an Indemnified Party has paid or properly accrued or reasonably anticipates that it will have to pay or accrue Losses, and (B) specifying in reasonable detail the individual items of Losses included in the amount so stated, -50-

the date each such item was paid or properly accrued, or the basis for such reasonably anticipated liability, and the nature of the misrepresentation, breach of warranty or covenant or otherwise to which such item is related, the Escrow Agent shall, subject to the provisions of Section 7.2(e) hereof, transfer to Parent out of the Escrow Fund, as promptly as practicable, funds held in the Escrow Fund in an amount equal to such Losses. Such payments from the Escrow Fund will be made with reference to each stockholder's Pro Rata Escrow Basis. (e) Objections to Claims. At the time of delivery of any -------------------- Officer's Certificate to the Escrow Agent, a duplicate copy of such certificate shall be delivered to the Stockholder Representative and for a period of thirty (30) days after such delivery, the Escrow Agent shall make no transfer to Parent of any Escrow Amounts pursuant to Section 7.2(d) hereof unless the Escrow Agent shall have received written authorization from the Stockholder Representative to make such transfer. After the expiration of such thirty (30) day period, the Escrow Agent shall transfer the funds from the Escrow Fund in accordance with Section 7.2(d) hereof, provided that no such transfer may be made if the Stockholder Representative shall object in a written statement to the claim made in the Officer's Certificate, and such statement shall have been delivered to the Escrow Agent prior to the expiration of such thirty (30) day period. (f) Resolution of Conflicts; Arbitration. ------------------------------------ (i) In case the Stockholder Representative shall object in writing to any claim or claims made in any Officer's Certificate as provided in Section 7.2(e) hereof, the Stockholder Representative and Parent shall attempt in good faith to agree upon the rights of the respective parties with respect to each of such claims. If the Stockholder Representative and Parent should so agree, a memorandum setting forth such agreement shall be prepared and signed by both parties and shall be furnished to the Escrow Agent. The Escrow Agent shall be entitled to rely on any such memorandum and distribute funds from the Escrow Fund in accordance with the terms thereof. (ii) If no such agreement can be reached after good faith negotiation, either Parent or the Stockholder Representative may demand arbitration of the matter unless the amount of the damage or loss is at issue in pending litigation with a third party, in which event arbitration shall not be commenced until such amount is ascertained or both parties agree to arbitration; and in either such event the matter shall be settled by arbitration conducted by three arbitrators. Parent and the Stockholder Representative shall each select one arbitrator, and the two arbitrators so selected shall select a third arbitrator. The arbitrators shall set a limited time period and establish procedures designed to reduce the cost and time for discovery while allowing the parties an opportunity, adequate in the sole judgment of the arbitrators, to discover relevant information from the opposing parties about the subject matter of the dispute. The arbitrators shall rule upon motions to compel or limit discovery and shall have the authority to impose sanctions, including attorneys fees and costs, to the extent as a court of competent law or equity, should the arbitrators determine that discovery was sought without substantial justification or that discovery was refused or objected to without substantial justification. The decision of a majority of the three arbitrators as to the validity and amount of any claim in such Officer's Certificate shall be binding -51-

and conclusive upon the parties to this Agreement, and notwithstanding anything in Section 7.2(e) hereof, the Escrow Agent shall be entitled to act in accordance with such decision and make or withhold payments out of the Escrow Fund in accordance therewith. Such decision shall be written and shall be supported by written findings of fact and conclusions which shall set forth the award, judgment, decree or order awarded by the arbitrators. (iii) Judgment upon any award rendered by the arbitrators may be entered in any court having jurisdiction. Any such arbitration shall be held in Marin County, California under the rules then in effect of the American Arbitration Association. For purposes of this Section 7.2(f), in any arbitration hereunder in which any claim or the amount thereof stated in the Officer's Certificate is at issue, Parent shall be deemed to be the prevailing party in the event that the arbitrators award Parent an amount equal to at least the sum of one-half (1/2) of the disputed amount plus any amounts not in dispute; otherwise, the Stockholder Representative shall be deemed to be the prevailing party. The non-prevailing party to an arbitration shall pay its own expenses, the fees of each arbitrator, the administrative costs of the arbitration, and the expenses, including without limitation, reasonable attorneys fees and costs, incurred by the other party to the arbitration. (g) Third-Party Claims. In the event Parent becomes aware of a ------------------ third-party claim that Parent reasonably believes may result in a demand against the Escrow Fund, Parent shall notify the Stockholder Representative of such claim, and the Stockholder Representative shall be entitled, at its expense, to participate in any defense of such claim. Parent shall have the right in its sole discretion to control the defense of all such claims and to settle any such claim; provided, however, that no settlement of any such claim with third-party claimants shall be the sole determining factor of the amount of any claim against the Escrow Fund, except with the consent of the Stockholder Representative. In the event that the Stockholder Representative has consented to any such settlement and acknowledged that the claim is a valid claim against the Escrow Fund, the Stockholder Representative shall be deemed to have agreed to the claim by Parent against the Escrow Fund in an amount equal to such settlement. (h) Stockholder Representative; Power of Attorney. --------------------------------------------- (i) In the event that the Merger is approved, effective upon such vote, and without further act of any stockholder, Irwin Jungreis, shall be appointed as agent and attorney-in-fact (the "Stockholder Representative") for each stockholder of the Company (except such stockholders, if any, as shall have exercised their dissenters' rights under Delaware Law), for and on behalf of stockholders of the Company, to give and receive notices and communications, to authorize delivery to Parent of cash from the Escrow Fund in satisfaction of claims by Parent, to object to such deliveries, to agree to, negotiate, enter into settlements and compromises of, and demand arbitration and comply with orders of courts and awards of arbitrators with respect to such claims, and to take all actions necessary or appropriate in the judgment of Stockholder Representative for the accomplishment of the foregoing. Such agency may be changed by the stockholders of the Company from time to time upon not less than thirty (30) days prior written notice to Parent; provided that the Stockholder Representative may not be removed unless holders of a two-thirds interest of the Escrow Fund agree to such removal and to the identity of the substituted -52-

agent. Any vacancy in the position of Stockholder Representative may be filled by approval of the holders of a majority in interest of the Escrow Fund. No bond shall be required of the Stockholder Representative, and the Stockholder Representative shall not receive compensation for his or her services. Notices or communications to or from the Stockholder Representative shall constitute notice to or from each of the stockholders of the Company. (ii) The Stockholder Representative shall not be liable for any act done or omitted hereunder as Stockholder Representative in good faith, absent gross negligence. The stockholders of the Company on whose behalf the Escrow Amount was contributed to the Escrow Fund shall severally indemnify the Stockholder Representative and hold the Stockholder Representative harmless against any loss, liability or expense incurred without gross negligence or bad faith on the part of the Stockholder Representative and arising out of or in connection with the acceptance or administration of the Stockholder Representative's duties hereunder, including the reasonable fees and expenses of any legal counsel retained by the Stockholder Representative. (i) Actions of the Stockholder Representative. A decision, act, ----------------------------------------- consent or instruction of the Stockholder Representative shall constitute a decision of all the stockholders for whom a portion of the Escrow Amount otherwise issuable to them are deposited in the Escrow Fund and shall be final, binding and conclusive upon each of such stockholders, and the Escrow Agent and Parent may rely upon any such decision, act, consent or instruction of the Stockholder Representative as being the decision, act, consent or instruction of each such stockholder of the Company. The Escrow Agent and Parent are hereby relieved from any liability to any person for any acts done by them in accordance with such decision, act, consent or instruction of the Stockholder Representative. (j) Escrow Agent's Duties. --------------------- (i) The Escrow Agent shall be obligated only for the performance of such duties as are specifically set forth herein, and as set forth in any additional written escrow instructions that the Escrow Agent may receive after the date of this Agreement that are signed by an officer of Parent and the Stockholder Representative, and may rely and shall be protected in relying or refraining from acting on any instrument reasonably believed to be genuine and to have been signed or presented by the proper party or parties. The Escrow Agent shall not be liable for any act done or omitted hereunder as Escrow Agent while acting in good faith and in the exercise of reasonable judgment, and any act done or omitted pursuant to the advice of counsel shall be conclusive evidence of such good faith, provided that the Escrow Agent has exercised reasonable care in the selection of such counsel. (ii) The Escrow Agent is hereby expressly authorized to disregard any and all warnings given by any of the parties hereto or by any other person, excepting only orders or process of courts of law or the arbitrators, and is hereby expressly authorized to comply with and obey orders, judgments or decrees of any court or the arbitrators. In case the Escrow Agent obeys or complies with any such order, judgment or decree of any court, the Escrow Agent shall not be liable to any of the parties hereto or to any other person by reason of such compliance, notwithstanding any -53-

such order, judgment or decree being subsequently reversed, modified, annulled, set aside, vacated or found to have been entered without jurisdiction. (iii) The Escrow Agent shall not be liable in any respect on account of the identity, authority or rights of the parties executing or delivering or purporting to execute or deliver this Agreement or any documents or papers deposited or called for hereunder absent gross negligence or willful misconduct. (iv) The Escrow Agent shall not be liable for the expiration of any rights under any statute of limitations with respect to this Agreement or any documents deposited with the Escrow Agent absent gross negligence or willful misconduct. (v) In performing any duties under the Agreement, the Escrow Agent shall not be liable to any party for damages, losses, or expenses, except for gross negligence or willful misconduct on the part of the Escrow Agent. The Escrow Agent shall not incur any such liability for (A) any act or failure to act made or omitted in good faith, or (B) any action taken or omitted in reliance upon any instrument, including any written statement of affidavit provided for in this Agreement that the Escrow Agent shall in good faith believe to be genuine, nor will the Escrow Agent be liable or responsible for forgeries, fraud, impersonations, or determining the scope of any representative authority. In addition, the Escrow Agent may consult with the legal counsel in connection with Escrow Agent's duties under this Agreement and shall be fully protected in any act taken, suffered, or permitted by him/her in good faith in accordance with the advice of counsel provided that the Escrow Agent has exercised reasonable care in the selection of such counsel. The Escrow Agent is not responsible for determining and verifying the authority of any person acting or purporting to act on behalf of any party to this Agreement. (vi) If any controversy arises between the parties to this Agreement, or with any other party, concerning the subject matter of this Agreement, its terms or conditions, the Escrow Agent will not be required to determine the controversy or to take any action regarding it. The Escrow Agent may hold all documents and funds held in escrow and may wait for settlement of any such controversy by final appropriate legal proceedings. In such event, the Escrow Agent will not be liable for damage. Furthermore, the Escrow Agent may at its option, file an action of interpleader requiring the parties to answer and litigate any claims and rights among themselves. The Escrow Agent is authorized to deposit with the clerk of the court all documents and funds held in escrow, except all cost, expenses, charges and reasonable attorneys fees incurred by the Escrow Agent due to the interpleader action and which the parties jointly and severally agree to pay. Upon initiating such action, the Escrow Agent shall be fully released and discharged of and from all obligations and liabilities imposed by the terms of this Agreement. (vii) The parties and their respective successors and assigns agree jointly and severally to indemnify and hold Escrow Agent harmless against any and all losses, claims, damages, liabilities, and expenses, including reasonable costs of investigation, attorneys fees, and disbursements that may be imposed on Escrow Agent or incurred by Escrow Agent in connection -54-

with the performance of his/her duties under this Agreement, including but not limited to any litigation arising from this Agreement or involving its subject matter. (viii) The Escrow Agent may resign at any time upon giving at least thirty (30) days written notice to the parties; provided, however, that no such resignation shall become effective until the appointment of a successor escrow agent, which shall be accomplished as follows: the parties shall use their best efforts to mutually agree on a successor escrow agent within thirty (30) days after receiving such notice. If the parties fail to agree upon a successor escrow agent within such time, the Escrow Agent shall have the right to appoint a successor escrow agent authorized to do business in the State of California. The successor escrow agent shall execute and deliver an instrument accepting such appointment and it shall, without further acts, be vested with all the estates, properties, rights, powers and duties of the predecessor escrow agent as if originally named as escrow agent. The Escrow Agent shall be discharged from any further duties and liability under this Agreement. (k) Fees. All fees of the Escrow Agent for performance of its ---- duties hereunder shall be paid by Parent. It is understood that the fees and usual charges agreed upon for services of the Escrow Agent shall be considered compensation for ordinary services as contemplated by this Agreement. In the event that the conditions of this Agreement are not promptly fulfilled, or if the Escrow Agent renders any service not provided for in this Agreement, or if the parties request a substantial modification of its terms, or if any controversy arises, or if the Escrow Agent is made a party to, or intervenes in, any litigation pertaining to this escrow or its subject matter, the Escrow Agent shall be reasonably compensated by Parent for such extraordinary services and reimbursed for all costs, attorneys fees, and expenses occasioned by such default, delay, controversy or litigation. (l) Escrow as the Sole Remedy. The Escrow Fund shall be the sole ------------------------- and exclusive source of satisfaction of any claim made by the Indemnified Parties for any Losses resulting from the matters set forth in this Article VII and the Indemnified Parties shall have no other right of indemnification against the Indemnifying Stockholders with respect to any other information, documents or materials furnished to Parent or Merger Sub or any of their officers, directors, employees, agents or advisors; provided that nothing herein shall limit any remedy of an Indemnified Party for fraud, intentional misrepresentation or willful misconduct, and nothing herein shall limit the liability of the Company for any breach of any representation, warranty or covenant if the Merger does not close.
