4.7 Investment Representations. In connection with the offer, purchase and sale of the Shares, Purchaser makes the following representations:

(a) Purchase for Own Account. Purchaser is acquiring the Shares for its own account, not as nominee or agent, for investment and not for, with a view to, or for resale in connection with, any distribution or public offering thereof within the meaning of the Securities Act. Purchaser does not presently have any contract, undertaking or agreement with any Person to sell, transfer or grant participation rights to such Person or to any other Person with respect to any of the Shares acquired by Purchaser hereunder. Purchaser has not been organized solely for purposes of acquiring the Shares.

(b) Restricted Securities. Purchaser understands that the Shares are being offered and sold to it in reliance upon specific exemptions from the registration requirements of the Securities Act and state securities laws and that the Company is relying upon the truth and accuracy of, and Purchaser's compliance with, the representations, warranties, agreements, acknowledgments and understandings of Purchaser set forth herein in order to determine the availability of such exemptions and the eligibility of Purchaser to acquire the Shares.  Purchaser understands that the Shares, when issued, shall be "restricted securities" under the federal securities laws inasmuch as they are being acquired from the Company in a transaction not involving a public offering and that under such laws the Shares may be resold without registration under the Securities Act only in certain limited circumstances. Consequently, Purchaser may have to bear the risk of owning the Shares for an indefinite period of time. Purchaser is familiar with Rule 144 as presently in effect.

(c) Purchaser Status.  At the time Purchaser was offered the Shares, it was, and as of the date of this Agreement and the Closing Date is, an "accredited investor" as defined in Regulation D, Rule 501(a), promulgated under the Securities Act.

(d) Knowledge and Experience of Purchaser.  Purchaser has such knowledge, sophistication and experience in business and financial matters so as to be capable of evaluating the merits and risks of the prospective investment in the Shares, and has so evaluated the merits and risks of such investment.  Purchaser has had the opportunity to review the SEC Documents and to ask questions of, and receive answers from, the officers of the Company concerning the Company, including its financial condition, results of operation and prospects, and the terms and conditions of the offering of the Shares sufficient to enable it to evaluate its investment. Purchaser has received all of the information it considers necessary or appropriate for deciding whether to purchase the Shares hereunder. Purchaser understands that its investment in the Shares involves a significant degree of risk, including a risk of total loss of Purchaser's investment.  Purchaser understands that the market price of the Common Stock has been volatile and that no representation is being made as to the future value of the Common Stock.  Purchaser is able to bear the economic risk of an investment in the Shares and is able to afford a complete loss of such investment.

(e) Sufficient Funds. Purchaser has sufficient funds to deliver the Purchase Price in full and to consummate the transactions contemplated by this Agreement in accordance with the terms hereof.

(f) Legend. Purchaser understands that, until such time as a Registration Statement has been declared effective or the Shares may be sold pursuant to Rule 144 under the Securities Act without any restriction as to the number of securities as of a particular date that can then be immediately sold, the certificates evidencing the Shares will bear with one or all of the following restrictive legends:

(i) "THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "ACT"), OR UNDER THE SECURITIES LAWS OF ANY STATE OR OTHER JURISDICTION, AND HAVE BEEN ACQUIRED FOR INVESTMENT AND NOT WITH A VIEW TO, OR IN CONNECTION WITH, THE SALE OR DISTRIBUTION THEREOF. THESE SECURITIES ARE SUBJECT TO RESTRICTIONS ON TRANSFERABILITY AND RESALE AND MAY NOT BE TRANSFERRED OR RESOLD EXCEPT AS PERMITTED UNDER THE ACT AND ANY APPLICABLE STATE SECURITIES LAWS, PURSUANT TO REGISTRATION OR EXEMPTION THEREFROM (AND UNLESS THE COMPANY HAS RECEIVED AN OPINION OF COUNSEL SATISFACTORY TO THE COMPANY AND ITS COUNSEL THAT SUCH REGISTRATION IS NOT REQUIRED). THE TRANSFER OF THE SECURITIES EVIDENCED BY THIS CERTIFICATE IS SUBJECT TO CERTAIN RESTRICTIONS SET FORTH IN A STOCK PURCHASE AGREEMENT BETWEEN THE COMPANY AND PURCHASER OF SUCH SECURITIES.  THE COMPANY AND ITS TRANSFER AGENT WILL NOT BE OBLIGATED TO RECOGNIZE OR GIVE EFFECT TO ANY TRANSFER MADE IN VIOLATION OF SUCH RESTRICTIONS. A COPY OF SUCH RESTRICTIONS MAY BE OBTAINED FROM THE COMPANY UPON WRITTEN REQUEST.";

5.3 Exceptions to Section 5.2 Standstill Provisions. Notwithstanding the foregoing, the obligations under Section 5.1 shall terminate as to Purchaser and its Affiliates in the event that:

(a) the Company publicly announces a decision of the Company Board to conduct a formal process to sell all or substantially all of the assets of the Company; provided that the restrictions in Section 5.1 will automatically be reinstated and be in full force and effect if and at such time as the Company publicly announces a termination of such process;

5.5 Market Stand-Off Agreement. During the Lock-Up Period, Purchaser agrees that in connection with any registration of the Company's securities that, upon the request of the Company or the underwriters managing any underwritten offering of the Company's securities, not to sell, make any short sale of, loan, grant any option for the purchase of, or otherwise dispose of any Registrable Securities without the prior written consent of the Company or such underwriters, as the case may be, for such period of time from the effective date of such registration as the Company or the underwriters may specify.

6. Registration Rights.

6.1 Demand Registration. At any time following the Lock-Up Period, Purchaser may request in writing ("Request") (which Request will specify the Registrable Securities intended to be disposed and the intended method of distribution thereof) that the Company register under the Securities Act all or part of the Registrable Securities that are Beneficially Owned by Purchaser (a) on a Registration Statement on Form S-3 or other available form (a "Demand Registration") or (b) on a Shelf Registration Statement covering any Registrable Securities (or otherwise designating an existing Shelf Registration Statement with the SEC to cover the Registrable Securities) ("Shelf Registration").  Each Request pursuant to this Section 6.1 will be in writing and will specify the number of Registrable Securities requested to be registered.

6.2 Restrictions on Demand Registrations. Notwithstanding anything to the contrary in this Agreement, Purchaser may not make more than three Requests for Demand Registration and not more than three Requests for Shelf Registration.  The Company may on up to two occasions postpone for up to 120 days the filing or the effectiveness of a Registration Statement if the Board of Directors of the Company determines in good faith that such Demand Registration or Shelf Registration, as the case may be, would reasonably be expected to have a material adverse effect on any acquisition of assets (other than in the ordinary course of business), merger, consolidation, tender offer or any other material business transaction by the Company; provided that in such event, Purchaser will be entitled to withdraw such Request and, if such Request is withdrawn, such Request will not count as one of the permitted Requests.

6.3 Selection of Underwriters; Underwritten Offering.  If Purchaser so elects in writing delivered to the Company, the Company will use its reasonable best efforts to cause a Demand Registration to be in the form of an underwritten offering.  The Company will have the right to select the managing underwriter and managers to administer the offering, subject to such managing underwriter being a nationally recognized investment bank reasonably acceptable to Purchaser. Purchaser may not participate in any registration hereunder which is underwritten unless Purchaser (a) agrees to sell the Registrable Securities held by Purchaser on the basis provided in any underwriting agreement with the underwriters and (b) completes and executes all questionnaires, powers of attorney, indemnities, underwriting agreements and other documents reasonably required under the terms of such underwriting arrangements.

6.4 Piggyback Registrations.

(a) If the Company determines to register any of its securities either for its own account or the account of a security holder or holders, other than a registration pursuant to Section 6.1, a registration relating solely to employee or director benefit plans or employee dividend reinvestment plans, a registration relating to the offer and sale of debt securities, a registration relating solely to a corporate reorganization (including by way of merger of the Company with any other business) or acquisition of another business or a registration on any registration form that does not permit secondary sales (a "Piggyback Registration"), the Company will (i) promptly give written notice of the proposed Piggyback Registration to Purchaser and (ii) subject to Sections 6.4(b) and 6.4(c), include in such Piggyback Registration and in any underwriting involved therein all of such Registrable Securities as are specified in a written request or requests made by Purchaser received by the Company within 10 Business Days after such written notice from the Company is given to Purchaser.

(b) If a Piggyback Registration is an underwritten primary registration on behalf of the Company, and the managing underwriters advise the Company in writing that in their opinion the number of securities requested to be included in such registration exceeds the number which can be sold in an orderly manner in such offering within a price range acceptable to the Company, the Company will include in such registration (i) first, the securities the Company proposes to sell, (ii) second, the securities requested to be included in such registration by holders that are contractually entitled to include such securities therein pursuant to any written agreement entered into by the Company prior to the date of this Agreement (the "Other Registrable Securities") pro rata, on the basis of the number of shares of Common Stock held by Purchaser and the holders of the other Registrable Securities and the Registrable Securities requested to be included in such registration by Purchaser and (iii) third, any other securities requested to be included in such registration. If a Piggyback Registration is an underwritten secondary registration on behalf of any holder of Other Registrable Securities, and the managing underwriters advise the Company in writing that in their opinion the number of securities requested to be included in such registration exceeds the number which can be sold in an orderly manner in such offering within a price range acceptable to the holders of Other Registrable Securities, the Company will include in such registration (A) first, the Other Registrable Securities requested to be included in such registration by the holders thereof, (B) second, the Registrable Securities requested to be included in such registration by Purchaser and (C) third, any other securities requested to be included in such registration.

(c) The Company and any holder of Other Registrable Securities initiating any registration will have the right to, in its sole discretion, defer, terminate or withdraw any registration initiated by it under this Section 6.4 whether or not Purchaser has elected to include any Registrable Securities in such registration. Notwithstanding anything contained herein, in the event that the SEC or applicable federal securities laws and regulations prohibit the Company from including all of the Registrable Securities requested by Purchaser to be registered in a registration statement pursuant to this Section 6.4, then the Company will be obligated to include in such registration statement only such limited portion of the Registrable Securities as is permitted by the SEC or such federal securities laws and regulations.

    6.5 Withdrawals.  Purchaser may withdraw all or any part of the Registrable Securities from a Registration Statement at any time prior to the effective date of such Registration Statement.  If such withdrawal is made primarily as a result of the failure of the Company to comply with any provision of this Agreement, then such Request will not count as one of the permitted Requests and the Company will be responsible for the payment of all Registration Expenses in connection with such registration.  In the case of any other withdrawal, Purchaser may elect either to pay for the Registration Expenses associated with the withdrawn registration or to forfeit one request.

    6.6 Registration Procedures.  Whenever Purchaser has made a Request in accordance with Section 6.1 that any Registrable Securities be registered pursuant to this Agreement, the Company will:

(a) not later than the 30th calendar day after the receipt by the Company of such a Request, prepare and file with the SEC a Required Registration Statement or Required Shelf Registration Statement, as the case may be, providing for the registration under the Securities Act of the Registrable Securities which the Company has been so requested to register in accordance with the intended methods of distribution thereof specified in such Request or  requests, and will use reasonable best efforts to have such Required Registration Statement or Required Shelf Registration Statement, as the case may be, declared effective by the SEC as soon as practicable thereafter and to keep such Required Registration Statement or Required Shelf Registration Statement, as the case may be, continuously effective (i) in the case of a Demand Registration, for a period of at least 180 calendar days (or, in the case of an underwritten offering, such period as the underwriters will reasonably require) following the date on which such Required Registration Statement is declared effective (or such shorter period which will terminate when all of the Registrable Securities covered by such Required Registration Statement have been sold pursuant thereto) or (ii) in the case of a Shelf Registration, until such time as all Registrable Securities covered by such Required Shelf Registration Statement have been sold pursuant thereto, including, in either case, if necessary, by filing with the SEC a post-effective amendment or a supplement to the Required Registration Statement or Required Shelf Registration Statement or the related prospectus or any document incorporated therein by reference or by filing any other required document or otherwise supplementing or amending the Required Registration Statement or Required Shelf Registration Statement, if required by the rules, regulations or instructions applicable to the registration form used by the Company for such Required Registration Statement or Required Shelf Registration Statement or by the Securities Act, the Exchange Act, any state securities or blue sky laws, or any rules and regulations thereunder;

(b) prepare and file with the SEC such amendments and supplements to such Registration Statement and the prospectus used in connection therewith as may be necessary to comply with the provisions of the Securities Act with respect to the disposition of all securities covered by such Registration Statement for the period set forth in (a) above;

(c) furnish to Purchaser such number of copies of such Registration Statement, each amendment and supplement thereto, the prospectus included in such Registration Statement (including each preliminary prospectus) and such other documents as Purchaser may reasonably request in order to facilitate the disposition of the Registrable Securities owned by Purchaser;

(d) use its reasonable best efforts to register or qualify such Registrable Securities under such other securities or blue sky laws of such jurisdictions as Purchaser reasonably requests and do any and all other acts and things which may be reasonably necessary or advisable to enable Purchaser to consummate the disposition in such jurisdictions of the Registrable Securities owned by Purchaser; provided that the Company will not be required to (i) qualify generally to do business in any jurisdiction where it would not otherwise be required to qualify or (ii) consent to general service of process in any such jurisdiction;

(e) in the event of any underwritten public offering, enter into and perform its obligations under an underwriting agreement, in usual and customary form, with the managing underwriters of such offering and take such other actions as are prudent and reasonably required in order to expedite or facilitate the disposition of such Registrable Securities, including causing its officers to participate in "road shows" and other information meetings organized by the managing underwriters;

(f) notify Purchaser, at any time when a prospectus relating thereto is required to be delivered under the Securities Act, of the happening of any event as a result of which the prospectus included in such Registration Statement contains an untrue statement of a material fact or omits any fact necessary to make the statements therein not misleading, and in such case, the Company will promptly prepare a supplement or amendment to such prospectus so that, as thereafter delivered to the purchasers of such Registrable Securities, such prospectus will not contain an untrue statement of a material fact or omit to state any fact necessary to make the statements therein not misleading;

(g) use its reasonable best efforts to cause all such Registrable Securities which are registered to be listed on each securities exchange on which similar securities issued by the Company are then listed;

(h) enter into such customary agreements and take all such other actions as Purchaser or the underwriters, if any, reasonably request in order to expedite or facilitate the disposition of such Registrable Securities;

(i) make available for inspection by Purchaser, any underwriter participating in any disposition pursuant to such Registration Statement and any attorney, accountant or other agent retained by Purchaser or any underwriter, all financial and other records, pertinent corporate documents and properties of the Company, and cause the Company's officers, directors, employees and independent accountants to supply all information reasonably requested by Purchaser or any underwriter, attorney, accountant or agent in connection with such Registration Statement;

(j) if such sale is pursuant to an underwritten offering, use reasonable best efforts to obtain "comfort" letters dated the pricing date of the offering of the Registrable Securities and the date of the closing under the underwriting agreement from the Company's independent public accountants in customary form and covering such matters of the type customarily covered by "comfort" letters as the managing underwriter reasonably requests;

(k) use reasonable best efforts to furnish, at the request of Purchaser on the date such securities are delivered to the underwriters for sale pursuant to such registration or are otherwise sold pursuant thereto, an opinion, dated such date, of counsel representing the Company for the purposes of such registration, addressed to the underwriters, if any, and to the seller making such request, covering such legal matters with respect to the registration in respect of which such opinion is being given as the underwriters, if any, and the seller may reasonably request and are customarily included in such opinions;

(l) use reasonable best efforts to obtain the withdrawal of any order suspending the effectiveness of the Registration Statement registering such Registrable Securities;

(m) otherwise use its reasonable best efforts to comply with all applicable rules and regulations of the SEC, and make available to its security holders, as soon as reasonably practicable but no later than 15 months after the effective date of the Registration Statement, an earnings statement covering the period of at least twelve months beginning with the first day of the Company's first full calendar quarter after the effective date of the Registration Statement, which earnings statement will satisfy the provisions of Section 11(a) of the Securities Act and Rule 158 thereunder;

(n) cooperate with Purchaser and each underwriter participating in the disposition of such Registrable Securities and their respective counsel in connection with any filings required to be made with the Financial Industry Regulatory Authority;

(o) promptly notify in writing Purchaser and the underwriter, if any, of the following events:

(i)	the effectiveness of any such Registration Statement;

(ii)	any request by the SEC for amendments or supplements to the Registration Statement or the prospectus or for additional information and when same has been filed and become effective;

(iii)

the issuance by the SEC of any stop order suspending the effectiveness of the Registration Statement or the initiation of any proceedings by any person for that purpose; and

(p) if requested by any underwriter, agree, and cause the Company and any directors or officers of the Company to agree, to be bound by customer "lock-up" agreements restricting the ability to dispose of Company securities; and

(q) use reasonable best efforts to take all other steps reasonably necessary to effect the registration of the Registrable Securities contemplated hereby.

    6.7 Removal of Legends.  In the case of a transaction pursuant to clause (a) of the following sentence, Purchaser hereby covenants and agrees with the Company not to make any sale of the Registrable Securities under any Registration Statement without complying with the provisions of this Agreement and without causing the prospectus delivery requirements under the Securities Act to be satisfied. The legend set forth in Section 4.7 will be removed and the Company will issue a certificate without such legend if (a) such Registrable Securities are registered for resale under the Securities Act, (b) in connection with a sale, assignment or other transfer that may be made without registration under the applicable requirements of the Securities Act, or (c) Purchaser provides the Company with reasonable assurance that such Registrable Securities can be sold, assigned or transferred pursuant to Rule 144.  Following the effective date of the Registration Statement or other information or assurances referred to in the preceding sentence, the Company will as soon as reasonably practicable following the delivery by Purchaser to the Company or the Company's transfer agent of a legended certificate representing such Registrable Securities, deliver or cause to be delivered to Purchaser a certificate representing such Registrable Securities that is free from all restrictive and other legends.

6.8 Suspension.  Purchaser acknowledges that there may be times when the Company must suspend the use of the prospectus forming a part of the Registration Statement (a "Suspension") until such time as an amendment to the Registration Statement has been filed by the Company and declared effective by the SEC, or until such time as the Company has filed an appropriate report with the SEC pursuant to the Exchange Act.  Purchaser hereby covenants and agrees that it will not sell any Registrable Securities pursuant to such prospectus during the period commencing at the time at which the Company gives Purchaser written notice of a Suspension of the use of such prospectus and ending at the time the Company gives Purchaser written notice that Purchaser may thereafter effect sales pursuant to such prospectus (the "Suspension End Date"). Following the Suspension End Date, the Company will promptly notify Purchaser in writing that the use of the prospectus may be resumed and will provide Purchaser with a copy of any amendment to the Registration Statement or supplement to the prospectus.

    6.9 Registration Expenses.  All expenses incident to the Company's performance of or compliance with this Section 6, including all registration and filing fees, fees and expenses of compliance with securities or blue sky laws, printing expenses, messenger and delivery expenses, the Company's internal expenses (including all salaries and expenses of its officers and employees performing legal or accounting duties), the expense of any annual audit or quarterly review, the expense of any liability insurance, the expenses and fees for listing the securities to be registered on each securities exchange on which similar securities issued by the Company are then listed and fees and disbursements of counsel for the Company and all independent certified public accountants retained by the Company (all such expenses being herein called "Registration Expenses"), will be borne by the Company. Purchaser will pay all fees, costs and expenses of its counsel, accountants, advisers or representatives and all expenses of any broker's commission or underwriter's discount or commission relating to the registration and sale of Registrable Securities pursuant to this Agreement.

    6.10 Rule 144 Reporting.  With a view to making available to Purchaser the benefits of certain rules and regulations of the SEC which may permit the sale of the Registrable Securities to the public without registration, the Company agrees to use its reasonable best efforts to:

(a) make and keep public information available, as those terms are understood and defined in Rule 144 or any similar or analogous rule promulgated under the Securities Act, at all times after the effective date of the first registration filed by the Company for an offering of its securities to the general public;

(b) file with the SEC, in a timely manner, all reports and other documents required of the Company under the Exchange Act; and

(c) so long as Purchaser owns any Registrable Securities, furnish to Purchaser promptly upon request (i) a written statement by the Company as to its compliance with the reporting requirements of Rule 144 of the Securities Act and of the Exchange Act, (ii) a copy of the most recent annual or quarterly report of the Company filed with the SEC and (iii) such other reports and documents as Purchaser may reasonably request in connection with availing itself of any rule or regulation of the SEC allowing it to sell any such securities without registration.

    6.11 Company Indemnification.  The Company agrees to indemnify and hold harmless, to the extent permitted by law, Purchaser, its Affiliates and each of its and their respective directors, officers, partners, members and agents and directors and each Person, if any, who controls Purchaser (within the meaning of the Securities Act or the Exchange Act) from and against (i) any and all losses, claims, damages, liabilities and expenses whatsoever (including reasonable expenses of investigation and reasonable attorneys' fees and expenses) caused by, arising out of or relating to any untrue or alleged untrue statement of material fact contained in any Registration Statement, prospectus or preliminary prospectus or any amendment thereof or supplement thereto covering the resale of any Registrable Securities by or on behalf of Purchaser or any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein and (ii) any and all losses, claims, damages, liabilities and expenses whatsoever (including reimbursement as incurred, of reasonable expenses of investigation and reasonable attorneys' fees and expenses) to the extent of the aggregate amount paid in settlement of any litigation, or investigation or proceeding by any Governmental Authority, commenced or threatened, or of any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission, if such settlement is effected with the written consent of the Company (which will not be unreasonably withheld); in each case, except insofar as the same are caused by or based upon any information furnished in writing to the Company by Purchaser expressly for use therein.  In connection with an underwritten offering, the Company will indemnify any underwriters of the Registrable Securities, their directors and officers and each Person who controls such underwriters (within the meaning of the Securities Act or the Exchange Act) to the same extent as provided above with respect to the indemnification of Purchaser.

     6.12 Purchaser Indemnification.  Purchaser agrees to indemnify and hold harmless, to the extent permitted by law, the Company, its Affiliates, its and their respective directors, officers, partners, members and agents and each Person, if any, who controls the Company (within the meaning of the Securities Act or the Exchange Act) from and against any and all losses, claims, damages, liabilities and expenses (including reasonable expenses of investigation and reasonable attorneys' fees and expenses) caused by, arising out of or relating to any untrue or alleged untrue statement of material fact contained in the Registration Statement, prospectus or preliminary prospectus or any amendment thereof or supplement thereto covering the resale of any Registrable Securities by or on behalf of Purchaser or any omission or alleged omission of a 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 is contained in any information or affidavit so furnished in writing by Purchaser expressly stated to be used in connection with such Registration Statement; provided that the foregoing indemnity of Purchaser shall be limited to the gross proceeds of the offering received by Purchaser, unless such indemnity arises out of or is based on willful misconduct or fraud by Purchaser.

     6.13 Resolution of Claims.  Any Person entitled to indemnification pursuant to this Section 6 will give prompt written notice to the indemnifying party of any claim with respect to which it seeks indemnification; provided that the failure so to notify the indemnifying party will not relieve the indemnifying party of any liability that it may have to the indemnified party hereunder except to the extent that the indemnifying party is materially prejudiced or otherwise forfeits substantive rights or defenses by reason of such failure.  If notice of commencement of any such action is given to the indemnifying party as above provided, the indemnifying party will be entitled to participate in and, to the extent it may wish, jointly with any other indemnifying party similarly notified, to assume the defense of such action at its own expense, with counsel chosen by it and reasonably satisfactory to such indemnified party.  The indemnified party will have the right to employ separate counsel in any such action and participate in the defense thereof, but the fees and expenses of such counsel will be paid by the indemnified party unless (a) the indemnifying party agrees to pay the same, (b) the indemnifying party fails to assume the defense of such action with counsel reasonably satisfactory to the indemnified party or (c) the named parties to any such action (including any impleaded parties) include both the indemnifying party and the indemnified party and such parties have been advised by such counsel that either (i) representation of such indemnified party and the indemnifying party by the same counsel would be inappropriate under applicable standards of professional conduct or (ii) it is reasonably foreseeable that there will be one or more material legal defenses available to the indemnified party which are different from or additional to those available to the indemnifying party.  In any of such cases, the indemnified party will have the right to participate in the defense of such action with its own counsel, the reasonable fees and expenses of which will be paid by the indemnifying party, it being understood, however, that the indemnifying party will not be liable for the fees and expenses of more than one separate firm of attorneys (in addition to any local counsel) for all indemnified parties. No indemnifying party will be liable for any settlement entered into without its written consent.  No indemnifying party will, without the consent of such indemnified party, effect any settlement of any pending or threatened proceeding in respect of which such indemnified party is a party and indemnity has been sought hereunder by such indemnified party, unless such settlement includes an unconditional release of such indemnified party from all liability for claims that are the subject matter of such proceeding.

     6.14 Contribution.  If the indemnification provided for in Section 6.11 or 6.12 is held by a court of competent jurisdiction to be unavailable to an indemnified party with respect to any losses, claims, damages or liabilities referred to herein, the indemnifying party, in lieu of indemnifying such indemnified party thereunder, will to the extent permitted by applicable law contribute to the amount paid or payable by such indemnified party as a result of such loss, claim, damage or liability in such proportion as is appropriate to reflect the relative fault of the indemnifying party on the one hand and of the indemnified party on the other in connection with such loss, claim, damage or liability, as well as any other relevant equitable considerations. The relative fault of the indemnifying party and of the indemnified party will be determined by a court of law by reference to, among other things, if it relates to an untrue or alleged untrue statement of a material fact or the omission to state a material fact in a Registration Statement, prospectus or preliminary prospectus or any amendment thereof or supplement thereof covering the resale of any Registrable Securities by or on behalf of the holder of Registrable Securities, whether the untrue or alleged untrue statement of a material fact or the omission to state a material fact relates to information supplied by the indemnifying party or by the indemnified party and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.  The amount paid or payable by a party as a result of any loss, claim, damage or liability referred to above will be deemed to include, subject to the limitations set forth in this Section 6.14, any legal or other fees, charges or expenses reasonably incurred by such party in connection with any investigation or proceeding. The parties hereto agree that it would not be just and equitable if contribution pursuant to this Section 6.14 were determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to in this Section 6.14.  No Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) will be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation.
