     2.6 The Floor; Dollar Limit on Purchases.

          (a) In the event that the 10-Day VWAP does not equal or exceed the Floor, as calculated with respect to any Closing Date, then such Closing will not occur.

          (d) In the event that the Company furnishes to Seaside a certificate signed by the Chief Executive Officer or Chief Financial Officer of the Company stating that a material development or potential material development involving the Company has occurred which the Company would be obligated to disclose in the Prospectus Supplement, which disclosure would, in the good faith judgment of the Chief Executive Officer, Chief Financial Officer, General Counsel or the Board of Directors of the Company, be premature or otherwise inadvisable at such time, then such Subsequent Closing will not occur; provided, however, that the Company will not be permitted to cancel a Subsequent Closing pursuant to this Section 2.6(d) more than eight times during the term of this Agreement. In the event that a Subsequent Closing is cancelled pursuant to this Section 2.6(d), then an additional Subsequent Closing will be added to the end of the schedule set forth in the definition of Subsequent Closing Date as a replacement for the cancelled Subsequent Closing such that the number of Closings pursuant to this Agreement will remain unchanged as a consequence of the delivery of a certificate pursuant to this Section 2.6(d).

ARTICLE III
REPRESENTATIONS AND WARRANTIES

     3.1 Representations and Warranties of the Company. Except as set forth under the corresponding section of the Disclosure Schedules, which Disclosure Schedules may be updated before any Closing and shall be deemed a part hereof, the Company hereby makes the representations and warranties set forth below to Seaside as of the date hereof and as of each Closing Date (provided that representations and warranties that speak as of a specific date shall continue to be true and correct as of such Closing with respect to such date):

          (a) Subsidiaries. All of the significant subsidiaries (as that term is defined in Rule 1-02 of Regulation S-X promulgated by the Commission) of the Company are listed in the Company’s most recent Annual Report on Form 10-K as modified by any subsequent SEC Reports filed with the SEC (each a “Subsidiary”).

If the Company has no subsidiaries, then references in the Transaction Document to the Subsidiaries will be disregarded.

Neither the Company nor any Subsidiary is in violation or default of any of the provisions of its respective certificate or articles of incorporation, bylaws or other organizational or charter documents. Each of the Company and the Subsidiaries is duly qualified to conduct business and is in good standing as a foreign corporation or other entity in each jurisdiction in which the nature of the business conducted or property owned by it makes such qualification necessary, except where the failure to be so qualified or in good standing, as the case may be, would not reasonably be expected to result in a Material Adverse Effect and, to the knowledge of the Company, no Proceeding has been instituted in any such jurisdiction revoking,

limiting or curtailing or seeking to revoke, limit or curtail such power and authority or qualification.

          (c) Authorization; Enforcement. The Company has the requisite corporate power and authority to enter into and to consummate the transactions contemplated by the Transaction Document and otherwise to carry out its obligations thereunder. The execution and delivery of the Transaction Document by the Company and the consummation by it of the transactions contemplated thereby have been duly authorized by all necessary action on the part of the Company and its stockholders, and no further action is required by the Company or its stockholders in connection therewith other than in connection with the Required Approvals. The Transaction Document has been (or upon delivery will have been) duly executed by the Company and, when delivered in accordance with the terms hereof, will constitute the valid and binding obligation of the Company enforceable against the Company in accordance with its terms except (i) as limited by general equitable principles and applicable bankruptcy, insolvency, reorganization, moratorium and other laws of general application affecting enforcement of creditors’ rights generally, (ii) as limited by laws relating to the availability of specific performance, injunctive relief or other equitable remedies and (iii) insofar as indemnification and contribution provisions may be limited by applicable law.

          (d) No Conflicts. The execution, delivery and performance of the Transaction Document by the Company, the issuance and sale of the Shares at each Closing and the consummation by the Company of the other transactions contemplated thereby do not and will not (i) conflict with or violate any provision of the Company’s or any Subsidiary’s certificate or articles of incorporation, bylaws or other organizational or charter documents, or (ii) conflict with, violate or constitute a default (or an event that with notice or lapse of time or both would become a default) under, or result in the creation of any Lien upon any of the properties or assets of the Company or any Subsidiary pursuant to, or give to others any rights of termination, amendment, acceleration or cancellation (with or without notice, lapse of time or both) of, any agreement (written or oral), credit facility, debt or other instrument (evidencing a Company or Subsidiary debt or otherwise) to which the Company or any Subsidiary is a party or by which any property or asset of the Company or any Subsidiary is bound or affected, or (iii) subject to the Required Approvals, conflict with or result in a violation of (x) any law, rule or regulation to which the Company or a Subsidiary is subject (including federal and state securities laws and regulations), or by which any property or asset of the Company or a Subsidiary is bound or affected, or (y) any order, judgment, injunction, decree or other restriction of any court or governmental authority that names the Company or a Subsidiary or to or by which, to the Company’s knowledge, the Company or a Subsidiary or any property or asset thereof is bound or affected, except in the case of each of clauses (ii) and (iii), such as would not reasonably be expected to result in a Material Adverse Effect.

          (e) Filings, Consents and Approvals. The Company is not required to obtain any consent, waiver, authorization, approval or order of, give any notice to, or make any filing or registration with, any court or other federal, state, local or other governmental authority, the Trading Market or other Person (including its stockholders) in connection with the execution, delivery and performance by the Company of the Transaction Document, other than (i) the filing of the Prospectus Supplement and (ii) any notice filings or SEC Reports as are required to be made

following each Closing Date under applicable federal and state securities laws or under applicable rules and regulations of the Trading Market (collectively, the “Required Approvals”).

          (f) Issuance of the Shares. The Shares are duly authorized and, when issued and paid for in accordance with the Transaction Document, will be duly and validly issued, fully paid and nonassessable, free and clear of all Liens. The Company has reserved from its duly authorized capital stock the maximum number of shares of Common Stock issuable pursuant to this Agreement. The issuance by the Company to Seaside or the resale by Seaside of the Shares has been registered under the Securities Act and all of the Shares when delivered will be freely transferable and tradable on the Trading Market by Seaside without restriction (other than any restrictions arising solely from the status, acts or omissions of Seaside). The Registration Statement is effective and available for the issuance or the resale by Seaside of the Shares thereunder and the Company has not received any notice that the Commission has issued or intends to issue a stop-order with respect to the Registration Statement or that the Commission otherwise has suspended or withdrawn the effectiveness of the Registration Statement, either temporarily or permanently, or intends or has threatened in writing to do so.

Except as disclosed in the SEC Reports or Section 3.1(g) of the Disclosure Schedules, the issue and sale of the Shares will not obligate the Company to issue shares of Common Stock or other securities to any Person (other than Seaside) and will not result in a right of any holder of Company securities to adjust the exercise, conversion, exchange or reset price under such securities. All of the outstanding shares of capital stock of the Company are validly issued, fully paid and nonassessable, have been issued in material compliance with all federal and state securities laws and requirements of the Trading Market, and none of such outstanding shares was issued in violation of any preemptive rights or similar rights to subscribe for or purchase securities. No further approval or authorization of any stockholder or the Board of Directors of the Company is required for the issuance and sale of the Shares, other than the Required Approvals.

          (p) Approvals. The issuance and listing or quotation (as applicable) on the Trading Market of the Shares requires no further approvals, including but not limited to, the approval of stockholders.

          (q) Intellectual Property. The Company possesses such right, title and interest in and to, or possesses legal rights to use, all such patents, patent rights, trade secrets, inventions, know-how, trademarks, trade names, copyrights, service marks and other proprietary rights (“Intellectual Property”) as are material to the conduct of the Company’s business except Intellectual Property the failure of which to possess would not reasonably be expected to have a Material Adverse Effect. Except as disclosed in the SEC Reports, the Company has not received any notice of infringement, misappropriation or conflict from any third party as to Intellectual Property owned by or exclusively licensed to the Company that has not been resolved or disposed of, which infringement, misappropriation or conflict would, if the subject of an unfavorable decision, ruling or finding, reasonably be expected to have a Material Adverse Effect. To the Company’s knowledge, it has not infringed, misappropriated, or otherwise conflicted with the valid Intellectual Property of any third parties, which infringement, misappropriation or conflict would, if the subject of an unfavorable decision, ruling or finding, reasonably be expected to have a Material Adverse Effect.

          (r) Permits. The Company has made all filings, applications and submissions required by, and possesses all approvals, licenses, certificates, certifications, clearances, consents, exemptions, marks, notifications, orders, permits and other authorizations issued by, the appropriate federal, state or foreign regulatory authorities necessary to own or lease its properties

and to conduct its businesses (collectively, “Permits”), except for such Permits the failure of which to possess or obtain would not reasonably be expected to have a Material Adverse Effect. The Company has not received any written notice of proceedings relating to the limitation, revocation, cancellation, suspension, modification or non-renewal of any such Permit which, singly or in the aggregate, if the subject of an unfavorable decision, ruling or finding, would reasonably be expected to have a Material Adverse Effect, and has no reason to believe that any such Permit will not be renewed in the ordinary course.

          (s) Disclosure. The Company confirms that neither the Company nor any officer, director or employee of the Company acting on its behalf (as such term is used in Regulation FD) has provided Seaside or its agents or counsel with any information that constitutes or might reasonably be expected to constitute material, non-public information except insofar as the existence and terms of the proposed transactions hereunder may constitute such information. The Company understands and confirms that Seaside will rely on the foregoing representations and covenants in effecting transactions in securities of the Company. None of the representations and warranties of the Company contained herein, nor any statement made by the Company in any disclosure, schedule, exhibit, certificate or other document furnished or to be furnished to Seaside in connection herewith, contains or will contain any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements made therein, in light of the circumstances under which they were made, not misleading.

     3.2 Representations and Warranties of Seaside. Seaside hereby makes the representations and warranties set forth below to the Company as of the date hereof and as of each Closing Date (provided that representations and warranties that speak as of a specific date shall continue to be true and correct as of such Closing with respect to such date):

          (a) Organization; Authority. Seaside is a limited partnership duly organized, validly existing and in good standing under the laws of the state of Florida, with full right, power and authority to own and use its properties and assets and to carry on its business as currently conducted and to enter into and to consummate the transactions contemplated by this Agreement and otherwise to carry out its obligations hereunder and thereunder. The execution, delivery and performance by Seaside of the transactions contemplated by this Agreement have been duly authorized by all necessary action on the part of Seaside and no such further action is required. The Transaction Document has been (or upon delivery will have been) duly executed by Seaside, and, when delivered by Seaside in accordance with the terms thereof, will constitute the valid and legally binding obligation of Seaside, enforceable against it in accordance with its terms, except (i) as limited by general equitable principles and applicable bankruptcy, insolvency, reorganization, moratorium and other laws of general application affecting enforcement of creditors’ rights generally, (ii) as limited by laws relating to the availability of specific performance, injunctive relief or other equitable remedies and (iii) insofar as indemnification and contribution provisions may be limited by applicable law.

          (b) Experience of Seaside. Seaside, either alone or together with its representatives, 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. Seaside has access to sufficient capital to fund its anticipated obligations set forth in Sections 2.1 and 2.2. Seaside is

able to bear the economic risk of an investment in the Shares and, at the present time, is able to afford a complete loss of such investment.

          (c) Short Sales. Seaside has not directly or indirectly executed any Short Sales or other hedging transactions in the securities of the Company.

          (d) No Brokers or Finders. Except for Omni Capital Corporation, whose fees will be paid by the Company, no agent, broker, investment banker or other firm is or will be entitled to any broker’s or finder’s fee or any commission or similar fee from Seaside in connection with any of the transactions contemplated by this Agreement.

          (e) Limited Ownership. The purchase by Seaside of the Shares issuable to it at the Closings will not result in Seaside (individually or together with any other Person with whom Seaside has identified, or will have identified, itself as part of a “group” in a public filing made with the Commission involving the Company’s securities) acquiring, or obtaining the right to acquire, in excess of 19.9% of the outstanding shares of Common Stock or the voting power of the Company on a post-transaction basis that assumes that all Closings contemplated by this Agreement shall have occurred.

          (f) Investment Intent. Based on its past experience in transactions similar to the transaction contemplated by this Agreement and its intentions with respect to the Shares that are issuable to it under this Agreement, Seaside does not believe it is an underwriter.

ARTICLE IV
OTHER AGREEMENTS OF THE PARTIES

     4.1 No Transfer Restrictions. Certificates evidencing the Shares shall not contain any legend restricting their transferability by Seaside. The Company shall cause its counsel to issue a legal opinion to the Company’s transfer agent if required by the Company’s transfer agent to effect a transfer of any of the Shares; such opinion shall be provided by the Company’s counsel at no expense to Seaside.

     4.2 Securities Laws Disclosure; Publicity. The Company shall, by 9:00 a.m. Eastern time on the Trading Day following the date hereof, file a Current Report on Form 8-K which attaches as an exhibit this Agreement, in a form reasonably acceptable to Seaside and its counsel, if Seaside is readily available to review such Form 8-K in a timely manner, disclosing the material terms of the transactions contemplated hereby.

     4.3 Shareholders Rights Plan. No claim will be made or enforced by the Company or, with the consent of the Company, any other Person that Seaside is an “Acquiring Person” or similar designation under any shareholders rights plan or similar plan or arrangement in effect or hereafter adopted by the Company, or that Seaside could be deemed to trigger the provisions of any such plan or arrangement, by virtue of receiving Shares under the Transaction Document or under any other agreement between the Company and Seaside.

     4.4 Investment Company Status. The Company shall conduct its business in a manner so that it will not become subject to the Investment Company Act of 1940, as amended.

     4.5 Non-Public Information. The Company covenants and agrees that neither it nor any other Person acting on its behalf will provide Seaside or its agents or counsel with any information that the Company believes constitutes material non-public information. The Company understands and confirms that Seaside shall be relying on the foregoing representations in effecting transactions in securities of the Company. Seaside covenants and agrees that it shall not, and shall cause its counsel not to, knowingly request from the Company or any person acting on the Company’s behalf any material non-public information (other than any such information disclosed prior to the date of this Agreement).

     4.6 Indemnification of Seaside. Subject to the provisions of this Section 4.6, the Company will indemnify and hold Seaside and its respective directors, officers, stockholders, partners, members, employees, agents and Affiliates (each, a “Seaside Party”) harmless from any and all losses, liabilities, obligations, claims, contingencies, damages, costs and expenses, including all judgments, amounts paid in settlements, court costs and actual and reasonable attorneys’ fees and costs of investigation reasonably incurred in connection with defending or investigating any suit or action in respect thereof to which any Seaside Party is or reasonably believes it may become a party under the Securities Act, the Exchange Act or any other federal or state statutory law or regulation, at common law or otherwise, insofar as such losses, liabilities, obligations, claims, demands, contingencies, damages, costs and expenses arise out of or are based on (a) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or any Prospectus Supplement, or (b) the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, provided that the Company will not be liable in any such case to the extent that any such liability, obligation, claim, demand, contingency, damage, cost or expense arises out of or is based upon any untrue statement or alleged untrue statement or omission or alleged omission made therein in reliance upon and in conformity with written information furnished to the Company by and regarding Seaside expressly for inclusion therein. If any action shall be brought against any Seaside Party in respect of which indemnity may be sought pursuant to this Agreement, such Seaside Party shall promptly notify the Company in writing, and the Company shall have the right to assume the defense thereof with counsel of its own choosing. Any Seaside Party shall 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 shall be at the expense of such Seaside Party except to the extent that (i) the employment thereof has been specifically authorized by the Company in writing, (ii) the Company has failed after a reasonable period of time to assume such defense and to employ counsel or (iii) in such action there is, in the reasonable opinion of such separate counsel, a material conflict on any material issue between the position of the Company and the position of such Seaside Party such that common representation would be unethical or ineffective. The Company will not be liable to any Seaside Party under this Agreement (x) for any settlement by a Seaside Party effected without the Company’s prior written consent, which consent shall not be unreasonably withheld or delayed; or (y) to the extent, but only to the extent, that a loss, liability, obligation, claim, demand, damage, cost or expense is attributable to any Seaside Party’s breach of any of the representations, warranties, covenants or agreements made by Seaside in this Agreement.

     4.7 Listing or Quotation of Common Stock. The Company hereby agrees to use its best efforts to maintain the listing or quotation (as applicable) of the Common Stock on its current Trading Market and all other Trading Markets on which such Common Stock may hereafter be

listed or quoted (as applicable), and will comply in all respects with the Company’s reporting, filing and other obligations under the bylaws or rules of such Trading Market(s), provided that best efforts shall not require the expenditure of time or money that is unreasonable in light of the likelihood of success of the efforts. The Company further agrees that, if the Company applies to have the Common Stock traded on any Trading Market other than its current Trading Market, it will include in such application all of the Shares and will take such other action as is reasonably necessary to cause all of the Shares to be listed on such other Trading Market.

     4.8 Stockholder Approval. The Company shall not issue shares of Common Stock or Common Stock Equivalents, if such issuance would require stockholder approval pursuant to applicable rules of the Trading Market, unless and until such stockholder approval is obtained.

     4.9 Short Sales; Limits on Trading. Seaside covenants that neither it nor any Person acting on its behalf or pursuant to any understanding with it will (a) execute any Short Sales in the securities of the Company from the date hereof until the final Subsequent Closing contemplated hereby, or (b) sell a quantity of Shares that exceeds 10% of the total number of shares of Common Stock traded on any Trading Day.

     4.10 Prospectus Supplement. The Company will use its best efforts to file the Prospectus Supplement in accordance with the requirements of Rule 424 promulgated under the Securities Act on or before the Initial Closing Date and, if required, before each Subsequent Closing Date.

ARTICLE V
MISCELLANEOUS

     5.1 Termination. This Agreement may be terminated by the Company, immediately upon written notice to Seaside; provided, however, that no such termination pursuant to this Section 5.1 will affect the right of any party to sue for any breach by the other party (or parties).

     5.2 Fees and Expenses. Except as otherwise set forth in this Agreement and as set forth in this Section 5.2 below, each party shall pay the fees and expenses of its own advisers, counsel, accountants and other experts, if any, and all other expenses incurred by such party incident to the negotiation, preparation, execution, delivery and performance of this Agreement. The Company shall pay all stamp and other taxes and duties levied in connection with the delivery of the Shares. Notwithstanding the foregoing, at the Initial Closing the Company shall reimburse Seaside for the fees and expenses of its counsel, White White & Van Etten PC, in an amount equal to $25,000 and at each Subsequent Closing the Company shall reimburse Seaside for the fees and expenses of its counsel, White White & Van Etten PC, in an amount equal to $2,500. Such legal fees may be withheld by Seaside from the amount to be paid for the Shares purchased at the Initial Closing and any Subsequent Closing.

     5.3 Entire Agreement. The Transaction Document, together with the exhibits and schedules thereto (including the Disclosure Schedules), contain the entire understanding of the parties with respect to the subject matter hereof and supersede all prior agreements and understandings, oral or written, with respect to such matters, which the parties acknowledge have been merged into such documents, exhibits and schedules.

     5.4 Notices. Any and all notices or other communications or deliveries required or permitted to be provided hereunder shall be in writing and shall be deemed given and effective on the earliest of (a) the date of transmission, if such notice or communication is delivered via electronic mail or facsimile at the electronic mail address or facsimile number set forth on the signature pages attached hereto prior to 5:30 p.m. (Eastern time) on a Trading Day, (b) the next Trading Day after the date of transmission, if such notice or communication is delivered via electronic mail or facsimile at the electronic mail address or facsimile number set forth on the signature pages attached hereto on a day that is not a Trading Day or later than 5:30 p.m. (Eastern time) on any Trading Day, (c) the second Trading Day following the date of mailing, if sent by U.S. nationally recognized overnight courier service, or (d) upon actual receipt by the party to whom such notice is required to be given. The address for such notices and communications shall be as set forth on the signature pages attached hereto or as otherwise provided in writing from time to time by the addressee to the other party.

     5.5 Amendments; Waivers. No provision of this Agreement may be waived or amended except in a written instrument signed, in the case of an amendment, by the Company and Seaside or, in the case of a waiver, by the party against whom enforcement of any such waiver is sought. No waiver of any default with respect to any provision, condition or requirement of this Agreement shall be deemed to be a continuing waiver in the future or a waiver of any subsequent default or a waiver of any other provision, condition or requirement hereof, nor shall any delay or omission of either party to exercise any right hereunder in any manner impair the exercise of any such right.

     5.6 Headings. The headings herein are for convenience only, do not constitute a part of this Agreement and shall not be deemed to limit or affect any of the provisions hereof. The language used in this Agreement will be deemed to be the language chosen by the parties to express their mutual intent, and no rules of strict construction will be applied against any party.

     5.7 Successors and Assigns. This Agreement shall be binding upon and inure to the benefit of the parties and their successors and permitted assigns. Neither party may assign this Agreement or any rights or obligations hereunder without the prior written consent of other party; provided that Seaside may assign its rights and obligations under this Agreement to an affiliate of Seaside without obtaining the Company’s prior written consent so long as the assignee shall agree in writing to be bound by such obligations and provided that Seaside shall in any event remain liable for the obligations of any such assignee under this Agreement.

     5.8 No Third-Party Beneficiaries. This Agreement is intended for the benefit of the parties hereto and their respective successors and permitted assigns and is not for the benefit of, nor may any provision hereof be enforced by, any other Person, except as otherwise set forth in Section 4.6.

     5.9 Governing Law. All questions concerning the construction, validity, enforcement and interpretation of the Transaction Document shall be governed by and construed and enforced in accordance with the internal laws of the State of New York, without regard to the principles of conflicts of law thereof. The parties hereby waive all rights to a trial by jury. If either party shall commence an action or proceeding to enforce any provisions of the Transaction Document, then the prevailing party in such action or proceeding shall be reimbursed by the other party for its

reasonable attorneys’ fees and other costs and expenses incurred with the investigation, preparation and prosecution of such action or proceeding.

     5.10 Survival. The representations and warranties herein shall survive the Closings and delivery of the Shares for the applicable statute of limitations.

     5.11 Execution. This Agreement may be executed in two or more counterparts, all of which when taken together shall be considered one and the same agreement and shall become effective when counterparts have been signed by each party and delivered to the other party, it being understood that both parties need not sign the same counterpart. In the event that any signature is delivered by facsimile or email transmission, such signature shall create a valid and binding obligation of the party executing (or on whose behalf such signature is executed) with the same force and effect as if such facsimile or email signature page were an original thereof.

     5.12 Severability. If any provision of this Agreement is held to be invalid or unenforceable in any respect, the validity and enforceability of the remaining terms and provisions of this Agreement shall not in any way be affected or impaired thereby and the parties will attempt to agree upon a valid and enforceable provision that is a reasonable substitute therefor, and upon so agreeing, shall incorporate such substitute provision in this Agreement.

     5.13 Rescission and Withdrawal Right. Notwithstanding anything to the contrary contained in (and without limiting any similar provisions of) the Transaction Document, whenever one party exercises a right, election, demand or option under the Transaction Document and the other party does not timely perform its related obligations within the periods therein provided, then the exercising party may rescind or withdraw, in its sole discretion from time to time upon written notice to the other party, any relevant notice, demand or election in whole or in part without prejudice to its future actions and rights.

     5.14 Remedies. In addition to being entitled to exercise all rights provided herein or granted by law, including recovery of damages, Seaside and the Company will be entitled to specific performance under the Transaction Document. The parties agree that monetary damages may not be adequate compensation for any loss incurred by reason of any breach of the obligations set forth herein and hereby agree to waive in any such action for specific performance of any such obligation the defense that a remedy at law would be adequate.

     5.15 Payment Set Aside. To the extent that either party hereto makes a payment or payments to the other party hereto pursuant to the Transaction Document or enforces or exercises its rights thereunder, and such payment or payments or the proceeds of such enforcement or exercise or any part thereof are subsequently invalidated, declared to be fraudulent or preferential, set aside, recovered from, disgorged by or are required to be refunded, repaid or otherwise restored to the other party, a trustee, receiver or any other person under any law (including, without limitation, any bankruptcy law, state or federal law, common law or equitable cause of action), then to the extent of any such restoration the obligation or part thereof originally intended to be satisfied shall be revived and continued in full force and effect as if such payment had not been made or such enforcement or setoff had not occurred.

     5.16 Construction. The parties agree that each of them and/or their respective counsel has reviewed and had an opportunity to revise the Transaction Document and, therefore, the normal rule of construction to the effect that any ambiguities are to be resolved against the drafting party shall not be employed in the interpretation of the Transaction Document or any amendments hereto.
