Ladies & Gentlemen:

     TeleCommunication Systems, Inc., a Maryland corporation (the “Company”), proposes to issue and sell to Oppenheimer & Co. Inc. and the other initial purchasers named on Schedule I to this Agreement, for whom Oppenheimer & Co. Inc. and Raymond James & Associates Inc. are acting as Representatives (the “Representatives”) (the “Initial Purchasers”), $90,000,000 in aggregate principal amount of 4.5% Convertible Senior Notes due 2014 (the “Firm Notes”), subject to the terms and conditions set forth herein.

     1. The Transaction. Subject to the terms and conditions herein contained, the Company proposes to issue and sell to the Initial Purchasers, severally and not jointly, the Firm Notes which are convertible into the Class A common stock $0.01 par value per share (the “Common Stock”) of the Company. In addition, the Company proposes to grant to the Initial Purchasers an option to purchase up to an additional $13,500,000 principal amount of Notes from the Company (the “Option Notes”) pursuant to the terms hereof. The Firm Notes and the Option Notes are collectively referred to herein as the “Securities”. The Securities are to be issued under an Indenture between the Company and The Bank of New York Mellon, as trustee (the “Trustee”) (the “Indenture”).

     The amounts of the Securities to be purchased by each of the several Initial Purchasers are set forth opposite their names on Schedule I hereto.

     In connection with the sale of the Securities, the Company has prepared a preliminary offering memorandum, dated November 9, 2009 (the “Preliminary Offering Memorandum”), and has prepared a final offering memorandum, dated the date hereof (the “Offering Memorandum”), each setting forth information regarding the Company, the Securities, the terms of the Offering and the transactions contemplated by the Transaction Documents (as defined below), and any material developments relating to the Company occurring after the date of the most recent financial statements included therein. Any references herein to the Preliminary Offering Memorandum or the Offering Memorandum shall be deemed to include, in each case, all amendments and supplements thereto and any information and/or documents incorporated by reference therein. The Company hereby confirms that it has authorized the use of the Disclosure Package (as defined below) and the Offering Memorandum in connection with the offering and resale of the Securities by the Initial Purchasers.

     The Company understands that the Initial Purchasers propose to make an offering of the Securities (the “Exempt Resales”) only on the terms and in the manner set forth in the Disclosure Package and the Offering Memorandum, as amended or supplemented, and the terms hereof as soon as the Initial Purchasers deem advisable after this Agreement has been executed and delivered, solely to persons in the United States whom the Initial Purchasers reasonably believe to be “qualified institutional buyers” (each, a “QIB”) as defined in Rule 144A under the Securities Act of 1933, as amended (the “Securities Act”), as such rule may be amended from time to time (“Rule 144A”) in transactions under Rule 144A or pursuant to another exemption from registration requirements of the Securities Act. The QIBs are referred to herein from time to time as the “Eligible Purchasers.” The Initial Purchasers will offer the Securities to such Eligible Purchasers initially at a price equal to 100% of the principal amount thereof. Such price may be changed by the Initial Purchasers at any time without notice.

     The Securities are convertible in accordance with their terms and the terms of the Indenture into shares of Common Stock (except for any cash in lieu of fractional shares) at an initial conversion rate of 96.637 shares of Common Stock per $1,000 principal amount of Securities.

     This Agreement, the Securities, and the Indenture are hereinafter referred to collectively as the “Transaction Documents.”

     Any references herein to “Exchange Act Reports” herein include all documents filed by the Company with the Securities and Exchange Commission (the “Commission”) pursuant to Section 13(a), 13(c) or 15(d) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). Unless stated to the contrary, any references herein to the terms “amend”, “amendment” or “supplement” with respect to the Disclosure Package or the Offering Memorandum shall be deemed to refer to all Exchange Act Reports filed subsequent to the date of this Agreement that are incorporated by reference therein.

     Capitalized terms used herein and not otherwise defined shall have the meanings assigned to such terms in the Disclosure Package, and if not defined therein, in the Indenture.

     4. Purchase, Sale and Delivery. On the basis of the representations, warranties, covenants and agreements contained in this Agreement, and subject to its terms and conditions:

          (a) The Company agrees to issue and sell to the several Initial Purchasers, and each of the Initial Purchasers agrees, severally and not jointly, to purchase from the Company, at a purchase price of 100% of the principal amount thereof, plus accrued interest, if any, from November 10, 2009 to the Closing Date, as defined below (the “Initial Price”), the aggregate amount of Firm Notes. The Company hereby grants to each of the Initial Purchasers an option to purchase all or any part of the Option Notes at the Initial Price. The aggregate amount of Option

Notes to be purchased by each of the Initial Purchasers shall be the same percentage of the Option Notes to be purchased by each of the Initial Purchasers as such Initial Purchaser is purchasing of the Firm Notes. Such option may be exercised in whole or in part at any time on or before 12:00 noon, New York City time, on the business day before the Firm Notes Closing Date (as defined below), and from time to time thereafter within 30 days after the date of this Agreement, in each case upon written, facsimile or telegraphic notice, or verbal or telephonic notice confirmed by written, facsimile or telegraphic notice, by each of the Initial Purchasers to the Company no later than 12:00 noon, New York City time, on the business day before the Firm Notes Closing Date or at least two business days before the Option Notes Closing Date (as defined below), as the case may be, setting forth the aggregate amount of Option Notes to be purchased and the time and date (if other than the Firm Notes Closing Date) of such purchase.

          (b) Payment of the purchase price for, and delivery of, the Firm Notes shall be made at the offices of Oppenheimer & Co. Inc., 300 Madison Avenue, New York, New York 10017, at 10:00 a.m., New York City time, on November 16, 2009 or at such time on such other date, not later than ten (10) business days after the date of this Agreement, as shall be agreed upon by the Company and the Representatives (such time and date of delivery and payment are called the “Firm Notes Closing Date”. In addition, in the event that any or all of the Option Notes are purchased by the Initial Purchasers, payment of the purchase price, and delivery of the certificates, for such Option Notes shall be made at the above-mentioned offices, or at such other place as shall be agreed upon by the Initial Purchasers and the Company, on each date of delivery as specified in the notice from the Initial Purchasers to the Company (such time and date of delivery and payment are called the “Option Notes Closing Date”). The Firm Notes Closing Date and any Option Notes Closing Dates are called, individually, a “Closing Date” and, together, the “Closing Dates”.

          (c) Payment for the Securities shall be made to the Company by wire transfer of immediately available funds or by certified or official bank check or checks payable in New York Clearing House (same day) funds drawn to the order of the Company, against delivery of the Securities to the Representatives for the respective accounts of the Initial Purchasers.

          (d) On each Closing Date the Company will deliver to the Initial Purchasers, in such denomination or denominations and registered in such name or names as the Representatives request upon notice to the Company at least 48 hours prior to the Closing Date, one or more Securities in definitive form, registered in such name and in such denominations as the Initial Purchasers shall request, having an aggregate amount corresponding to the aggregate principal amount of the Securities sold pursuant to Exempt Resales to QIBs and Individual Accredited Investors (the “Definitive Note”), against payment of the purchase price therefor by wire transfer of same-day funds to the account of the Company, previously designated by it in writing. The Definitive Note shall be made available to the Initial Purchasers for inspection not later than 5:00 p.m., New York City time, on the business day immediately preceding each Closing Date.

     5. Offering by Initial Purchasers. The Initial Purchasers propose to make an offering of the Securities at the price and upon the terms set forth in the Offering Memorandum as soon as practicable after this Agreement is entered into and as, in the judgment of the Initial Purchasers, is advisable.

     6. Agreements of the Company. The Company covenants and agrees with the Initial Purchasers that:

          (a) The Company shall advise the Initial Purchasers promptly and, if requested by the Representative, confirm such advice in writing, (i) of the issuance by any state securities commission or other regulatory authority of any stop order or order suspending the qualification or exemption from qualification of any Securities for offering or sale in any jurisdiction, or the initiation of any proceeding for such purpose by any state securities commission or other regulatory authority and (ii) of the happening of any event that makes any statement of a material fact made in the Disclosure Package or the Offering Memorandum untrue or that requires the making of any additions to or changes in the Disclosure Package or the Offering Memorandum in order to make the Disclosure Package or the Offering Memorandum not misleading in the light of the circumstances existing at the time it is delivered to an Eligible Purchaser. The Company shall use their commercially reasonable efforts to prevent the issuance of any stop order or order suspending the qualification or exemption from qualification of any Securities under any state securities or blue sky laws and, if at any time any state securities commission or other regulatory authority shall issue an order suspending the qualification or exemption from qualification of any Securities under any state securities or blue sky laws, the Company shall use its commercially reasonable efforts to obtain the withdrawal or lifting of such order at the earliest possible time.

          (b) The Company shall, without charge, provide to the Initial Purchasers and to counsel to the Initial Purchasers, and to those persons identified by the Initial Purchasers to the Company as many copies of the Preliminary Offering Memorandum and the Offering Memorandum, and any amendments or supplements thereto, as the Initial Purchasers may reasonably request. The Company consents to the use of the Preliminary Offering Memorandum and the Offering Memorandum, and any amendments and supplements thereto required pursuant hereto, by the Initial Purchasers in connection with Exempt Resales.

          (c) The Company will not amend or supplement the Preliminary Offering Memorandum or the Offering Memorandum or any other document used in connection with the offer and sale of the Securities or any amendment or supplement thereto during such period as, in the opinion of counsel for the Initial Purchasers, the Preliminary Offering Memorandum or the Offering Memorandum is required by law to be delivered in connection with Exempt Resales and in connection with market-making activities of the Initial Purchasers for so long as any Notes are outstanding unless the Initial Purchasers shall previously have been advised thereof and furnished a copy for a reasonable period of time prior to the proposed amendment or supplement and as to which the Initial Purchasers shall not have given their consent, which shall not be unreasonably withheld.

          (d) If, during the period referred to in 6(c) above, any event shall occur as a result of which, it is necessary or advisable, in the opinion of counsel for the Initial Purchasers, to amend or supplement the Preliminary Offering Memorandum or the Offering Memorandum or any other document used in connection with the offer and sale of the Securities in order to make such Preliminary Offering Memorandum or Offering Memorandum or such other document not misleading in the light of the circumstances existing at the time it is delivered to an Eligible Purchaser, or if for any other reason it shall be reasonably necessary or advisable to amend or

supplement the Preliminary Offering Memorandum or the Offering Memorandum or such other document to comply with applicable laws, rules or regulations, the Company shall (subject to Section 6(c) hereof) forthwith amend or supplement such Preliminary Offering Memorandum or Offering Memorandum or such other document at its own expense so that, as so amended or supplemented, such Preliminary Offering Memorandum or Offering Memorandum or such other document will not include an untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein not misleading or so that such Preliminary Offering Memorandum or Offering Memorandum or such other document will comply with all applicable laws, rules or regulations; if, during the period referred to in 6(c) above, the Company proposes to file with the SEC an Exchange Act Report that is incorporated by reference into the Offering Memorandum, a reasonable time prior to the proposed filing, the Company shall furnishes a copy of such Exchange Act Report to the Initial Purchasers for review and comment, and shall not file such document with the Commission until the Initial Purchasers have been afforded the opportunity to review and comment and the Initial Purchasers have not reasonably objected to the filing of such Exchange Act Report.

          (e) The Company shall cooperate with the Initial Purchasers and counsel for the Initial Purchasers in connection with the qualification or registration of the Securities for offering and sale under the securities or blue sky laws of such jurisdictions as the Representative may designate and shall continue such qualifications in effect for as long as may be necessary to complete the Exempt Resales; provided, however, that in connection therewith neither the Company shall be required to qualify as a foreign corporation where it is not now so qualified or to execute a general consent to service of process in any jurisdiction or to take any other action that would subject it to general service of process or to taxation in respect of doing business in any jurisdiction in which it is not otherwise subject, in each case, other than as to matters and transactions relating to the Preliminary Offering Memorandum, the Offering Memorandum or Exempt Resales.

          (f) If this Agreement shall terminate or shall be terminated after execution because of any failure or refusal on the part of the Company to comply with the terms or fulfill any of the conditions of this Agreement, the Company agrees to reimburse the Initial Purchasers for all reasonable out-of-pocket expenses (including reasonable fees and expenses of counsel for the Initial Purchasers) incurred by the Initial Purchasers in connection herewith.

          (g) The Company shall apply the net proceeds from the sale of the Securities in the manner set forth under “Use of Proceeds” in the Disclosure Package and the Offering Memorandum.

          (h) The Company shall not voluntarily claim, and shall actively resist any attempts to claim, the benefit of any usury laws against the holders of any Securities.

          (i) The Company shall do and perform all things required or necessary to be done and performed under this Agreement prior to or after each Closing Date and to satisfy all conditions precedent to the delivery of the Securities.

          (j) None of the Company or any of its “affiliates” (as defined in Rule 144 under the Securities Act) will sell, offer for sale, solicit offers to buy or otherwise negotiate in

respect of any “security” (as defined in the Securities Act) that could be integrated with the sale of the Securities in a manner that would require the registration under the Securities Act of the sale to the Initial Purchasers or the Eligible Purchasers of the Securities or to take any other action that would result in the Exempt Resales not being exempt from registration under the Securities Act.

          (k) For so long as any of the Securities remain outstanding and are “restricted securities” within the meaning of Rule 144(a)(3) under the Securities Act and are not able to be sold in their entirety under Rule 144 under the Securities Act (or any successor provision), for the benefit of holders from time to time of Securities, the Company will furnish at its expense, upon request, to any holder or beneficial owner of Notes and prospective purchasers of the Notes, information specified in Rule 144A(d)(4) under the Securities Act, unless the Company are then subject to and in compliance with Section 13 or 15(d) of the Exchange Act.

          (l) The Company shall comply with the representation letters to DTC relating to the approval of the Securities by DTC for “book-entry” transfer.

          (m) During the period of three years from the Closing Date, the Company shall deliver without charge to the Initial Purchasers (i) as soon as available, copies of each report and other communication (financial or otherwise) of the Company mailed to the Trustee of the holders of the Securities, stockholders or any national securities exchange on which any class of securities of the Company may be listed (including without limitation, press releases) other than materials filed with or furnished to the Commission and (ii) from time to time such other information concerning the Company as the Initial Purchasers may reasonably request.

          (n) The Company shall not take, directly or indirectly, any action which constitutes or is designed to cause or result in, or which could reasonably be expected to constitute, cause or result in, the stabilization or manipulation of the price of any security of the Company to facilitate the sale or resale of the Securities or the Common Stock issuable upon conversion thereof, or take any action prohibited by Regulation M under the Exchange Act, in connection with the distribution of the Securities contemplated hereby. The Company will not distribute any (i) preliminary offering memorandum, including, without limitation, the Preliminary Offering Memorandum, (ii) offering memorandum, including, without limitation, the Offering Memorandum or (iii) other offering material in connection with the offering and sale of the Securities.

          (o) For so long as the Securities constitute “restricted” securities within the meaning of Rule 144(a)(3) under the Securities Act, the Company shall not, and shall not permit any subsidiary to, solicit any offer to buy or offer to sell the Securities by means of any form of general solicitation or general advertising (as those terms are used in Regulation D under the Securities Act) or in any manner involving a public offering within the meaning of Section 4(2) of the Securities Act.

          (p) During the period from the Closing Date until one year after the Closing Date, without the prior written consent of the Initial Purchasers, the Company shall not, and shall not permit any of its “affiliates” (as defined in Rule 144 under the Securities Act) to, resell any of

the Securities that constitute “restricted securities” under Rule 144 that have been reacquired by any of them.

          (q) Prior to the Closing Date, except as required by law, not to issue any press release or other communications, directly or indirectly, or hold any press conference with respect to the issuance of the Securities, the Company, the properties, business, results of operations, condition (financial or otherwise), affairs or business prospects of the Company, without the prior consent of the Initial Purchasers, which shall not be unreasonably withheld. In such instance, the Company shall furnish a copy of any such release or communication to the Initial Purchasers for review and comment a reasonable time prior to its contemplated release.

          (r) Without the prior consent of the Initial Purchasers, not to make any offer relating to the Securities that would constitute a “free writing prospectus” (if the offering of the Securities was made pursuant to a registered offering under the Securities Act) as defined in Rule 405 under the Securities Act (a “Free Writing Offering Document”); any such Free Writing Offering Document the use of which has been consented to by the Initial Purchasers is listed on Schedule III hereto; if at any time following issuance of a Free Writing Offering Document any event occurred or occurs as a result of which such Free Writing Offering Document would conflict with the information in the Preliminary Offering Memorandum or the Offering Memorandum or would include an untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in light of the circumstances then prevailing, not misleading, the Company will give prompt notice thereof to the Initial Purchasers and, if requested by the Initial Purchasers, will prepare and furnish without charge to the Initial Purchasers a Free Writing Offering Document or other document which will correct such conflict, statement or omission.

     8. Indemnification.

          (a) The Company agrees to indemnify and hold harmless the Initial Purchasers and each person, if any, who controls the Initial Purchasers within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act against any and all losses, claims, damages and liabilities, joint or several (including any reasonable investigation, legal and other expenses incurred in connection with, and any amount paid in settlement of, any action, suit or proceeding or any claim asserted), to which they, or any of them, may become subject under the Securities Act, the Exchange Act or other Federal or state law or regulation, at common law or otherwise, insofar as such losses, claims, damages or liabilities arise out of or are based upon (i) any untrue statement or alleged untrue statement of a material fact contained in the Disclosure Package, any Free Writing Offering Document or the Offering Memorandum, or in any supplement thereto or amendment thereof, or in any electronic road show, or in any Blue

Sky application or other information or other documents executed by the Company filed in any state or other jurisdiction to qualify any or all of the Securities under the securities laws thereof (any such application, document or information being hereinafter referred to as a “Blue Sky Application”) or (ii) any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading; provided, however, that such indemnity shall not inure to the benefit of any Initial Purchaser (or any person controlling such Initial Purchaser) on account of any losses, claims, damages or liabilities arising from the sale of the Securities to any person by such Initial Purchaser if such untrue statement or omission or alleged untrue statement or omission was made in the Disclosure Package, any Free Writing Offering Document or the Offering Memorandum, or in any supplement thereto or amendment thereof, or in any electronic road show, or in any Blue Sky Application in reliance upon and in conformity with the Initial Purchaser Information (as defined in Section 11 hereto). This indemnity agreement will be in addition to any liability which the Company may otherwise have.

          (b) Each Initial Purchaser, severally and not jointly, agrees to indemnify and hold harmless the Company, each person, if any, who controls the Company within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, and the officers and directors of the Company, against any losses, claims, damages or liabilities to which such party may become subject, under the Securities Act, the Exchange Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in the Disclosure Package, any Free Writing Offering Document or the Offering Memorandum, or in any supplement thereto or amendment thereof, or arise out of or are based upon the omission or alleged omission to state therein, a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances in which they were made, not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in the Disclosure Package, any Free Writing Offering Document or the Offering Memorandum, or in any supplement thereto or amendment thereof, in reliance upon and in conformity with the Initial Purchaser Information; provided, however, that the obligation of any Initial Purchaser to severally and not jointly indemnify the Company (including any controlling person, director or officer thereof) shall be limited to the net proceeds received by the Company from such Initial Purchaser.

          (c) Any party that proposes to assert the right to be indemnified under this Section will, promptly after receipt of notice of commencement of any action, suit or proceeding against such party in respect of which a claim is to be made against an indemnifying party or parties under this Section, notify each such indemnifying party of the commencement of such action, suit or proceeding, enclosing a copy of all papers served. No indemnification provided for in Section 8(a) or 8(b) shall be available to any party who shall fail to give notice as provided in this Section 8(c) if the party to whom notice was not given was unaware of the proceeding to which such notice would have related and was prejudiced by the failure to give such notice but the omission so to notify such indemnifying party of any such action, suit or proceeding shall not relieve it from any liability that it may have to any indemnified party for contribution or otherwise than under this Section. In case any such action, suit or proceeding shall be brought against any indemnified party and it shall notify the indemnifying party of the commencement thereof, the indemnifying party shall be entitled to participate in, and, to the extent that it shall

wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel reasonably satisfactory to such indemnified party, and after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof and the approval by the indemnified party of such counsel, the indemnifying party shall not be liable to such indemnified party for any legal or other expenses, except as provided below and except for the reasonable costs of investigation subsequently incurred by such indemnified party in connection with the defense thereof. The indemnified party shall have the right to employ its counsel in any such action, but the fees and expenses of such counsel shall be at the expense of such indemnified party unless (i) the employment of counsel by such indemnified party has been authorized in writing by the indemnifying parties, (ii) the indemnified party shall have been advised by counsel that there may be one or more legal defenses available to it which are different from or in addition to those available to the indemnifying party (in which case the indemnifying parties shall not have the right to direct the defense of such action on behalf of the indemnified party) or (iii) the indemnifying parties shall not have employed counsel to assume the defense of such action within a reasonable time after notice of the commencement thereof, in each of which cases the reasonable fees and expenses of counsel shall be at the expense of the indemnifying parties. An indemnifying party shall not be liable for any settlement of any action, suit, and proceeding or claim effected without its written consent, which consent shall not be unreasonably withheld or delayed. No indemnifying party shall, without the prior written consent, which consent shall not be unreasonably withheld or delayed, of the indemnified party, effect any settlement of any proceeding or threatened proceeding in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party, unless (i) such settlement includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such proceeding and (ii) does not contain any factual or legal admission by or with respect to any indemnified party or any adverse statement with respect to the character, professionalism, expertise or reputation of any Indemnified Party or any action or inaction of any Indemnified Party.

     9. Contribution. In order to provide for just and equitable contribution in circumstances in which the indemnification provided for in Section 8(a) or 8(b) is due in accordance with its terms but for any reason is unavailable to or insufficient to hold harmless an indemnified party in respect to any losses, liabilities, claims, damages or expenses referred to therein, then each indemnifying party shall contribute to the aggregate losses, liabilities, claims, damages and expenses (including any investigation, legal and other expenses reasonably incurred in connection with, and any amount paid in settlement of, any action, suit or proceeding or any claims asserted, but after deducting any contribution received by any person entitled hereunder to contribution from any person who may be liable for contribution) incurred by such indemnified party, as incurred, in such proportion as is appropriate to reflect the relative benefits received by the Company, on the one hand, and the Initial Purchasers, on the other hand, from the offering of the Securities pursuant to this Agreement or, if such allocation is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to above but also the relative fault of the Company, on the one hand, and the Initial Purchasers, on the other hand, in connection with the statements or omissions which resulted in such losses, liabilities, claims, damages or expenses, as well as any other relevant equitable considerations. The Company and the Initial Purchasers agree that it would not be just and equitable if contribution pursuant to this Section 9 were determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to above. The

aggregate amount of losses, liabilities, claims, damages and expenses incurred by an indemnified party and referred to above shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue or alleged untrue statement or omission or alleged omission. Notwithstanding the provisions of this Section 9, no Initial Purchaser shall be required to contribute any amount in excess of the amount by which the total price at which the Securities resold by it to Eligible Purchasers were offered to the public exceeds the amount of damages which such Initial Purchaser has otherwise been required to pay by reason of any such 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. For purposes of this Section 9, each person, if any, who controls an Initial Purchaser within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act shall have the same rights to contribution as such Initial Purchaser, and each director of the Company, each officer of the Company, and each person, if any, who controls the Company within the meaning of the Section 15 of the Securities Act or Section 20 of the Exchange Act, shall have the same rights to contribution as the Company. Any party entitled to contribution will, promptly after receipt of notice of commencement of any action, suit or proceeding against such party in respect of which a claim for contribution may be made against another party or parties under this Section 9, notify such party or parties from whom contribution may be sought, but the omission so to notify such party or parties from whom contribution may be sought shall not relieve the party or parties from whom contribution may be sought from any other obligation it or they may have hereunder or otherwise than under this Section 9. No party shall be liable for contribution with respect to any action, suit, proceeding or claim settled without its written consent.

     The remedies provided for in Section 8 and this Section 9 are not exclusive and shall not limit any rights or remedies which otherwise may be available to any indemnified party in law or in equity.

     10. Conditions of Initial Purchasers Obligations. The obligations of the Initial Purchasers under this Agreement are several and not joint. The obligations of the Initial Purchasers to purchase and pay for the Securities, as provided herein, are subject to the absence from any certificates, opinions, written statements or letters furnished to the Initial Purchasers pursuant to this Section 10 of any misstatement or omissions and to the satisfaction of the following additional conditions unless waived in writing by the Representative:

          (a) All of the representations and warranties of the Company contained in this Agreement shall be true and correct on the date hereof and on each Closing Date with the same force and effect as if made on and as of the date hereof and the Closing Date, respectively.
