Stock (“Marketing Materials”), including any road show or investor presentations made to investors by the Company (whether in person or electronically), (ii) the omission or alleged omission to state in any Preliminary Prospectus, the Registration Statement or the Prospectus, or in any amendment or supplement thereto, or in any Marketing Materials, any material fact required to be stated therein or necessary to make the statements therein not misleading, or (iii) any act or failure to act or any alleged act or failure to act by any Underwriter in connection with, or relating in any manner to, the Stock or the offering contemplated hereby, and that is included as part of or referred to in any loss, claim, damage, liability or action arising out of or based upon matters covered by clause (i) or (ii) above (provided that the Company shall not be liable under this clause (iii) to the extent that it is determined in a final judgment by a court of competent jurisdiction that such loss, claim, damage, liability or action resulted directly from any such acts or failures to act undertaken or omitted to be taken by such Underwriter through its gross negligence or willful misconduct), and shall reimburse each Underwriter and each such officer, employee or controlling person promptly upon demand for any legal or other expenses reasonably incurred by that Underwriter, officer, employee or controlling person in connection with investigating or defending or preparing to defend against any such loss, claim, damage, liability or action as such expenses are incurred; provided, however, that the Company shall not be liable in any such case to the extent that any such loss, claim, damage, liability or action arises out of, or is based upon, any untrue statement or alleged untrue statement or omission or alleged omission made in any Preliminary Prospectus, the Registration Statement or the Prospectus, or in any such amendment or supplement, in reliance upon and in conformity with written information concerning such Underwriter furnished to the Company through the Representatives by or on behalf of any Underwriter specifically for inclusion therein which information consists solely of the information specified in Section 10(f); provided further, that the Company and its subsidiaries shall not be liable to the Underwriters or any of their respective directors, officers, employees or controlling persons with respect to any such untrue statement or omission made in any Preliminary Prospectus existing as of the date hereof that is corrected in the Prospectus if it is judicially determined that (i) the person asserting any such loss, claim, damage, liability or action purchased Stock from the Underwriters in reliance upon the Preliminary Prospectus but was not delivered or sent a copy of the Prospectus, if required by law, at or prior to the written confirmation of the sale of such Stock to such person, unless such failure to deliver or send the Prospectus was a result of noncompliance by the Company with Section 6 of this Agreement and (ii) the Underwriters, and each such officer, director, employee and controlling person, if any, would not have incurred such loss, claim, damage, liability or action had the Prospectus been delivered or sent. The foregoing indemnity agreement is in addition to any liability that the Company may otherwise have to any Underwriter or to any officer, employee or controlling person of that Underwriter.

(b) Each of the Selling Stockholders, severally in proportion to the number of shares of Stock to be sold by each of them hereunder, shall indemnify and hold harmless each Underwriter, its directors, officers and employees, and each person, if any, who controls any Underwriter within the meaning of the Securities Act, from and

against any loss, claim, damage or liability, joint or several, or any action in respect thereof (including, but not limited to, any loss, claim, damage, liability or action relating to purchases and sales of the Stock), to which that Underwriter, director, officer, employee or controlling person may become subject, under the Securities Act or otherwise, insofar as such loss, claim, damage, liability or action arises out of, or is based upon, (i) any untrue statement or alleged untrue statement of a material fact contained in any Preliminary Prospectus, the Registration Statement or the Prospectus or in any amendment or supplement thereto, (ii) the omission or alleged omission to state in any Preliminary Prospectus, the Registration Statement or the Prospectus, or in any amendment or supplement thereto, any material fact required to be stated therein or necessary to make the statements therein not misleading, but only to the extent that such untrue statement or omission or alleged untrue statement or omission relates to information provided to the Company or the Representatives in writing by such Selling Stockholder specifically for use in the Preliminary Prospectus, the Registration Statement or the Prospectus or (iii) the breach by such Selling Stockholder of any of the representations and warranties made by such Selling Stockholder in Section 2 hereof; and shall reimburse each Underwriter and any such director, officer or controlling person for any legal or other expenses reasonably incurred by such Underwriter or any such director, officer or controlling person in connection with investigating or defending or preparing to defend against any such loss, claim, damage, liability or action as such expenses are incurred; provided, however, that the Selling Stockholders shall not be liable in any such case to the extent that any such loss, claim, damage, liability or action arises out of, or is based upon, any untrue statement or alleged untrue statement or omission or alleged omission made in any Preliminary Prospectus, the Registration Statement or the Prospectus, or in any such amendment or supplement, in reliance upon and in conformity with written information concerning such Underwriter furnished to the Selling Stockholders through the Representatives by or on behalf of any Underwriter specifically for inclusion therein, which information consists solely of the information specified in Section 10(f); provided further, that the Selling Stockholders shall not be liable to the Underwriters or any of their respective directors, officers, employees or controlling persons with respect to any such untrue statement or omission made in any Preliminary Prospectus existing as of the date hereof that is corrected in the Prospectus if it is judicially determined that (i) the person asserting any such loss, claim, damage, liability or action purchased Stock from the Underwriters in reliance upon the Preliminary Prospectus but was not delivered or sent a copy of the Prospectus, if required by law, at or prior to the written confirmation of the sale of such Stock to such person, unless such failure to deliver or send the Prospectus was a result of noncompliance by the Company with Section 6 of this Agreement and (ii) the Underwriters, and each such officer, director, employee and controlling person, if any, would not have incurred such loss, claim, damage, liability or action had the Prospectus been delivered or sent. Notwithstanding any other provision of this Agreement, the liability of each Selling Stockholder pursuant to the provisions of this Section 10 shall be limited to an amount equal to the aggregate purchase price, less underwriting discounts and commissions, received by such Selling Stockholder from the sale of Stock hereunder by such Selling Stockholder. The foregoing indemnity agreement is in addition to any liability that the

Selling Stockholders may otherwise have to any Underwriter or to any director, officer, employee or controlling person of that Underwriter.

(c) Each Underwriter, severally and not jointly, shall indemnify and hold harmless the Company, each Selling Stockholder, each of their respective officers and employees, each of its directors, and each person, if any, who controls the Company or such Selling Stockholder within the meaning of the Securities Act, from and against any loss, claim, damage or liability, joint or several, or any action in respect thereof, to which the Company, such Selling Stockholder or any such director, officer or controlling person may become subject, under the Securities Act or otherwise, insofar as such loss, claim, damage, liability or action arises out of, or is based upon, (i) any untrue statement or alleged untrue statement of a material fact contained in any Preliminary Prospectus, the Registration Statement or the Prospectus or in any amendment or supplement thereto, or (ii) the omission or alleged omission to state in any Preliminary Prospectus, the Registration Statement or the Prospectus, or in any amendment or supplement thereto, any material fact required to be stated therein or necessary to make the statements therein not misleading, but in each case only to the extent that the untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with written information concerning such Underwriter furnished to the Company and the Selling Stockholders through the Representatives by or on behalf of that Underwriter specifically for inclusion therein, which information is limited to the information set forth in Section 10(f), and shall reimburse the Company, each Selling Stockholder and any such director, officer or controlling person for any legal or other expenses reasonably incurred by the Company or such Selling Stockholder or any such director, officer or controlling person in connection with investigating or defending or preparing to defend against any such loss, claim, damage, liability or action as such expenses are incurred. The foregoing indemnity agreement is in addition to any liability which any Underwriter may otherwise have to the Company, any Selling Stockholder or any such director, officer, employee or controlling person.

(d) Promptly after receipt by an indemnified party under this Section 10 of notice of any claim or the commencement of any action, the indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under this Section 10, notify the indemnifying party in writing of the claim or the commencement of that action; provided, however, that the failure to notify the indemnifying party shall not relieve it from any liability which it may have under this Section 10 except to the extent it has been materially prejudiced by such failure and, provided further, that the failure to notify the indemnifying party shall not relieve it from any liability which it may have to an indemnified party otherwise than under this Section 10. If any such claim or action shall be brought against an indemnified party, and it shall notify the indemnifying party thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it wishes, jointly with any other similarly notified indemnifying party, to assume the defense thereof with counsel reasonably satisfactory to the indemnified party. After notice from the indemnifying party to the indemnified party of its election to assume the defense of such claim or action, the indemnifying party shall not be liable to the

indemnified party under this Section 10 for any legal or other expenses subsequently incurred by the indemnified party in connection with the defense thereof other than reasonable costs of investigation; provided, however, that the indemnified party shall have the right to employ its own counsel if the named parties to such proceeding include both the indemnifying party and the indemnified party and representation of both parties by the same counsel would be, in the reasonable judgment of the indemnified party, inappropriate due to actual or potential differing interests between them or if, in the reasonable judgment of the indemnified party, the same counsel could not adequately represent the interests of both the indemnifying party and the indemnified party, and in that event the fees and expenses of such separate counsel for all indemnified parties shall be paid by the indemnifying party. It is understood that the indemnifying party shall not, in respect of the legal expenses of any indemnified party in connection with any proceeding or related proceedings, be liable for (i) the fees and expenses of more than one separate firm (in addition to any local counsel) for all Underwriters, its directors, officers and employees, and each person, if any, who controls any Underwriter within the meaning of the Securities Act, (ii) the fees and expenses of more than one separate firm (in addition to any local counsel) for the Company, its officers and employees, its directors, and each person, if any, who controls the Company within the meaning of the Securities Act, and (iii) the fees and expenses of more than one separate firm (in addition to any local counsel) for the Selling Stockholders, their officers and employees, their directors, and each person, if any, who controls any of the Selling Stockholders within the meaning of the Securities Act. No indemnifying party shall (i) without the prior written consent of the indemnified parties (which consent shall not be unreasonably withheld), settle or compromise or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified parties are actual or potential parties to such claim or action) unless such settlement, compromise or consent includes an unconditional release of each indemnified party from all liability arising out of such claim, action, suit or proceeding, or (ii) be liable for any settlement of any such action effected without its written consent (which consent shall not be unreasonably withheld), but if settled with the consent of the indemnifying party or if there be a final judgment of the plaintiff in any such action, the indemnifying party agrees to indemnify and hold harmless any indemnified party from and against any loss or liability by reason of such settlement or judgment to the extent provided in the Section 10.

(e) If the indemnification provided for in this Section 10 shall for any reason be unavailable to or insufficient to hold harmless an indemnified party under Section 10(a), 10(b) or 10(c) in respect of any loss, claim, damage or liability, or any action in respect thereof, referred to therein, then each indemnifying party shall, in lieu of indemnifying such indemnified party, contribute to the amount paid or payable by such indemnified party as a result of such loss, claim, damage or liability, or action in respect thereof, (i) in such proportion as shall be appropriate to reflect the relative benefits received by the Company and/or the Selling Stockholders on the one hand and the Underwriters on the other from the offering of the Stock or (ii) if the allocation provided

by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above, but also the relative fault of the Company and/or the Selling Stockholders on the one hand and the Underwriters on the other with respect to the statements or omissions which resulted in such loss, claim, damage or liability, or action in respect thereof, as well as any other relevant equitable considerations. The relative benefits received by the Company and the Selling Stockholders on the one hand and the Underwriters on the other with respect to such offering shall be deemed to be in the same proportion as the total net proceeds from the offering of the Stock purchased under this Agreement (before deducting expenses) received by the Company and the Selling Stockholders on the one hand, and the total underwriting discounts and commissions received by the Underwriters with respect to the shares of the Stock purchased under this Agreement, on the other hand, bear to the total gross proceeds from the offering of the shares of the Stock under this Agreement, in each case as set forth in the table on the cover page of the Prospectus. The relative fault shall be determined by reference to whether the untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Company, any Selling Stockholder or the Underwriters, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company, each Selling Stockholder and the Underwriters agree that it would not be just and equitable if contributions pursuant to this Section were to be determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation which does not take into account the equitable considerations referred to herein. The amount paid or payable by an indemnified party as a result of the loss, claim, damage or liability, or action in respect thereof, referred to above in this Section shall be deemed to include, for purposes of this Section 10(e), any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 10(e), no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Stock underwritten by it and distributed to the public was offered to the public exceeds the amount of any damages which such Underwriter has otherwise paid or become liable to pay by reason of any untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters’ obligations to contribute as provided in this Section 10(e) are several in proportion to their respective underwriting obligations and not joint.

(f) The Underwriters severally confirm and the Company and each Selling Stockholder acknowledges that (i) the statements with respect to the public offering of the Stock by the Underwriters set forth on the cover page of, (ii) the concession and reallowance figures appearing under the caption “Underwriting” in, (iii) the second paragraph under the caption “Underwriting – Commissions and Expenses” in, and (iv) the first and second paragraphs under the captions “Underwriting – Stabilization, Short Positions and Penalty Bids” and the paragraph under “Underwriting –

Discretionary Sales” in the Prospectus are correct and constitute the only information concerning such Underwriters furnished in writing to the Company by or on behalf of the Underwriters specifically for inclusion in the Preliminary Prospectus, the Registration Statement and the Prospectus.

SECTION 11. Defaulting Underwriters.

If, on either Delivery Date, any Underwriter defaults in the performance of its obligations under this Agreement, the remaining non-defaulting Underwriters shall be obligated to purchase the Stock which the defaulting Underwriter agreed but failed to purchase on such Delivery Date in the respective proportions which the number of shares of the Firm Stock set opposite the name of each remaining non-defaulting Underwriter in Schedule 1 hereto bears to the total number of shares of the Firm Stock set opposite the names of all the remaining non-defaulting Underwriters in Schedule 1 hereto; provided, however, that the remaining non-defaulting Underwriters shall not be obligated to purchase any of the Stock on such Delivery Date if the total number of shares of the Stock which the defaulting Underwriter or Underwriters agreed but failed to purchase on such date exceeds 9.09% of the total number of shares of the Stock to be purchased on such Delivery Date, and any remaining non-defaulting Underwriter shall not be obligated to purchase more than 110% of the number of shares of the Stock which it agreed to purchase on such Delivery Date pursuant to the terms of Section 4. If the foregoing maximums are exceeded, the remaining non-defaulting Underwriters, or those other underwriters satisfactory to the Representatives who so agree, shall have the right, but shall not be obligated, to purchase, in such proportion as may be agreed upon among them, all the Stock to be purchased on such Delivery Date. If the remaining Underwriters or other underwriters satisfactory to the Representatives do not elect to purchase the shares which the defaulting Underwriter or Underwriters agreed but failed to purchase on such Delivery Date, this Agreement (or, with respect to the Second Delivery Date, the obligation of the Underwriters to purchase, and of the Company and the Option Selling Stockholders to sell, the Option Stock) shall terminate without liability on the part of any non-defaulting Underwriter or the Company, except that the Company will continue to be liable for the payment of expenses to the extent set forth in Sections 8 and 13. As used in this Agreement, the term “Underwriter” includes, for all purposes of this Agreement unless the context requires otherwise, any party not listed in Schedule 1 hereto who, pursuant to this Section 11, purchases which a defaulting Underwriter agreed but failed to purchase.

Nothing contained herein shall relieve a defaulting Underwriter of any liability it may have to the Company or the Selling Stockholders for damages caused by its default. If other underwriters are obligated or agree to purchase the Stock of a defaulting or withdrawing Underwriter, either the Representatives or the Company may postpone the Delivery Date for up to seven full business days in order to effect any changes that in the opinion of counsel for the Company or counsel for the Underwriters may be necessary in the Registration Statement, the Prospectus or in any other document or arrangement.

SECTION 12. Termination. The obligations of the Underwriters hereunder may be terminated by the Representatives by notice given to and received by the Company prior to delivery of and payment for the Firm Stock if, prior to that time, any of the events described in Sections 9(j) or 9(k), shall have occurred or if the Underwriters shall decline to purchase the Stock for any reason permitted under this Agreement.

SECTION 13. Reimbursement of Underwriters’ Expense. If any Selling Stockholder shall fail to tender the Stock for delivery to the Underwriters by reason of any failure, refusal or inability on the part of the Company or any Selling Stockholder to perform any agreement on its part to be performed, or because any other condition of the Underwriters’ obligations hereunder required to be fulfilled by the Company or the Selling Stockholders (including, without limitation, with respect to the transactions) is not fulfilled, the Company will reimburse the Underwriters for all reasonable out-of-pocket expenses (including fees and disbursements of counsel) incurred by the Underwriters in connection with this Agreement and the proposed purchase of the Stock, and upon demand the Company shall pay the full amount thereof to the Representatives. If this Agreement is terminated pursuant to Section 11 by reason of the default of one or more Underwriters, neither the Company nor the Selling Stockholders shall be obligated to reimburse any defaulting Underwriter on account of those expenses.

SECTION 14. Notices, Etc. All statements, requests, notices and agreements hereunder shall be in writing, and:

(a) if to the Underwriters, shall be delivered or sent by mail, telex or facsimile transmission to Xxxxxx Brothers Inc., 1285 Avenue of the Xxxxxxxx, 00xx Xxxxx, Xxx Xxxx, Xxx Xxxx 00000, Attention: Syndicate Registration Department (Fax: 000-000-0000), with a copy, in the case of any notice pursuant to Section 10(d), to the Director of Litigation, Office of the General Counsel, Xxxxxx Brothers Inc., 000 Xxxx Xxxxxx, 00xx Xxxxx, Xxx Xxxx, XX 00000, and

Any such statements, requests, notices or agreements shall take effect at the time of receipt thereof. The Company shall be entitled to act and rely upon any request, consent, notice or agreement given or made on behalf of the Underwriters by Xxxxxx Brothers Inc. on behalf of the Representatives.

SECTION 16. Survival. The respective indemnities, representations, warranties and agreements of the Company, the Selling Stockholders and the Underwriters contained in this Agreement or made by or on behalf on them, respectively, pursuant to this Agreement, shall survive the delivery of and payment for the Stock and shall remain in full force and effect, regardless of any investigation made by or on behalf of any of them or any person controlling any of them.

SECTION 17. Definition of the Terms “Business Day” and “Subsidiary”. For purposes of this Agreement, (a) “business day” means each Monday, Tuesday, Wednesday, Thursday or Friday which is not a day on which banking institutions in New York are generally authorized or obligated by law or executive order to close and (b) “subsidiary” has the meaning set forth in Rule 405 of the Rules and Regulations.

Dear Sirs:

The undersigned understands that you and certain other firms propose to enter into an Underwriting Agreement (the “Underwriting Agreement”) providing for the purchase by you and such other firms (the “Underwriters”) of shares (the “Shares”) of Common Stock, par value $0.001 per share (the “Common Stock”), of Tessera Technologies, Inc., a Delaware corporation (the “Company”), and that the Underwriters propose to reoffer the Shares to the public (the “Offering”).

In consideration of the execution of the Underwriting Agreement by the Underwriters, and for other good and valuable consideration, the undersigned hereby irrevocably agrees that, without the prior written consent of Xxxxxx Brothers Inc., on behalf of the Underwriters, the undersigned will not, directly or indirectly, (1) offer for sale, sell, pledge, or otherwise dispose of (or enter into any transaction or device that is designed to, or could be expected to, result in the disposition by any person at any time in the future of) any shares of Common Stock (including, without limitation, shares of Common Stock that may be deemed to be beneficially owned by the undersigned in accordance with the rules and regulations of the Securities and Exchange Commission and shares of Common Stock that may be issued upon exercise of any option or warrant) or securities convertible into or exchangeable for Common Stock (other than any of the Shares) owned by the undersigned on the date of execution of this Lock-Up Letter Agreement or on the date of the completion of the Offering, or (2) enter into any swap or other derivatives transaction that transfers to another, in whole or in part, any of the economic benefits or risks of ownership of such shares of Common Stock, whether any such transaction described in clause (1) or (2) above is to be settled by delivery of Common Stock or other securities, in cash or otherwise, for a period of 90 days after the date of the final Prospectus relating to the Offering.

In furtherance of the foregoing, the Company and its Transfer Agent are hereby authorized to decline to make any transfer of securities if such transfer would constitute a violation or breach of this Lock-Up Letter Agreement.

The foregoing restrictions shall not apply to bona fide gifts or other transfers of shares of Common Stock, in each case that are made exclusively between and among the undersigned or members of the undersigned’s family, or affiliates of the undersigned, including its partners (if a partnership) or members (if a limited liability company); provided that it shall be a condition to any such transfer that (i) the transferee agrees to be bound by the terms of this Lock-Up Letter Agreement to the same extent as if the transferee were a party hereto, and (ii) no filing by any party (donor, donee, transferor or transferee) under the Securities Exchange Act of 1934, as amended, shall be required or shall be voluntarily made in connection with such transfer or distribution (other than a filing on a Form 5 made after the expiration of the 90-day period referred to above).

Notwithstanding anything herein to the contrary, if (i) during the last 17 days of the 90-day restricted period, the Company issues an earnings release or material news or a material event relating to the Company occurs; or (ii) prior to the expiration of the 90-day restricted period, the Company announces that it will release earnings results during the 16-day period beginning on the last day of the 90-day period, the restrictions imposed by this Agreement shall continue to apply until the expiration of the 18-day period beginning on the issuance of the earnings release or the occurrence of the material news or material event.

It is understood that, if the Company notifies you that it does not intend to proceed with the Offering, if the Underwriting Agreement does not become effective, or if the Underwriting Agreement (other than the provisions thereof which survive termination) shall terminate or be terminated prior to payment for and delivery of the Shares, the undersigned will be released from its obligations under this Lock-Up Letter Agreement. Furthermore, it is understood that the obligations accepted pursuant to this Lock-Up Letter Agreement are in addition to, and do not supercede, any similar obligations to which the undersigned may be bound.

The undersigned understands that the Company and the Underwriters will proceed with the Offering in reliance on this Lock-Up Letter Agreement.

Whether or not the Offering actually occurs depends on a number of factors, including market conditions. Any Offering will only be made pursuant to an Underwriting Agreement, the terms of which are subject to negotiation between the Company, the Underwriters and the Selling Stockholders named therein.

This Lock-Up Letter Agreement shall be governed by, and construed in accordance with, the laws of the State of New York.

The undersigned hereby represents and warrants that the undersigned has full power and authority to enter into this Lock-Up Letter Agreement and that, upon request, the undersigned will execute any additional documents necessary in connection with the enforcement hereof. Any obligations of the undersigned shall be binding upon the heirs, personal representatives, successors and assigns of the undersigned.

This Lock-Up Letter Agreement shall lapse and become null and void if the Offering shall not have occurred on or before July 31, 2004.


Very truly yours,

(v) The Registration Statement has become effective under the Securities Act. With your consent, based solely on a telephonic confirmation by a member of the Staff of the Commission on [date], to the best of our knowledge no stop order suspending the effectiveness of the Registration Statement has been issued under the Act and no proceedings therefor have been initiated by the Commission. Any required filing of the Prospectus pursuant to Rule 424 under the Act has been made in accordance with Rule 424 and 430A under the Act;

(vi) The Registration Statement, as of the date it was declared effective, and the Prospectus, as of its date, complied as to form in all material respects with the requirements for registration statements on Form S-1 under the Act and the rules and regulations of the Commission thereunder; it being understood, however, that we express no opinion with respect to Regulation S-T or the financial statements, schedules, or other financial data, included in, or omitted from, the Registration Statement or the Prospectus. In passing upon the compliance as to form of the Registration Statement and the Prospectus, we have assumed that the statements made therein are correct and complete;

(vii) The statements in the Prospectus under the caption “Description of Capital Stock,” insofar as they purport to constitute a summary of the terms of the Common Stock, and under the captions “Shares Available for Future Sale,” and “United States Federal Income Tax Consequences to Non-United States Holders,” insofar as they purport to summarize certain provisions of the statutes and regulations referred to therein, are accurate summaries in all material respects;

(viii) To the best of our knowledge, there are no contracts or documents of a character required to be described in the Registration Statement or Prospectus or to be filed as exhibits to the Registration Statement that are not described or filed;

(xi) With your consent based solely on a certificate of an officer of the Company as to factual matters and a review of the Material Agreements, except as described in the Prospectus, the Company is not a party to any agreement that would require the inclusion in the Registration Statement of shares owned by any person or entity other than the Selling Stockholders;

(xii) Neither the Company nor any subsidiary is an “investment company” as defined in the Investment Company Act;

(xiii) With your consent, based solely on a review of the Governing Documents and the Material Agreements, none of the Governing Documents or Material Agreements contains any restriction on voting or limitation on transfer affecting the Stock to be issued and sold to you, when so issued, which are not described or referred to in the Prospectus, other than the requirements of the DGCL and customary restrictions on transfer under state and federal securities laws;

(xiv) Upon indication by book entry that the shares of Stock listed on Schedule 2 to the Underwriting Agreement have been credited to securities accounts maintained by the Underwriters at the Depository Trust Company and payment therefor in accordance with the Underwriting Agreement, the several Underwriters will acquire a securities entitlement with respect to such shares of Stock and, under the New York UCC, an action based on an adverse claim to such securities entitlement, whether framed in conversion, replevin, constructive trust, equitable lien or other theory may not be asserted against the several Underwriters; and

(xv) Assuming the due authorization, execution and delivery of the Custody Agreement by or on behalf of each Selling Stockholder, the Custody Agreement constitutes a valid and binding agreement of such Selling Stockholder in accordance with its terms.

In rendering such opinion, such counsel may state that their opinion is limited to matters governed by the Federal laws of the United States of America, the laws of the State of New York and the General Corporation Law of the State of Delaware. The foregoing opinion and statement may be qualified by a statement to the effect that such counsel does not assume any responsibility for the accuracy, completeness or fairness of the statements contained in the Registration Statement or the Prospectus (other than as set forth in clause (vii) above).
