Section 6.4                                    Prior Negotiations; Entire Agreement.  This Agreement (including the exhibits hereto and the documents and instruments referred to in this Agreement) constitutes the entire agreement of the Parties and supersedes all prior agreements, arrangements or understandings, whether written or oral, between the Parties with respect to the subject matter of this Agreement.

Section 6.5                                    Governing Law; Venue; Arbitration.

(a)                                 Governing Law.  THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF MARYLAND WITHOUT REGARD TO PRINCIPLES OF CONFLICTS OF LAW.

(b)                                 Venue.  Each Party hereto agrees that it shall bring any Proceeding in respect of any claim arising out of or related to this Agreement or the Transaction exclusively in the courts of the State of Maryland and the Federal courts of the United States, in each case, located in the City of Baltimore (the “Chosen Courts”).  Solely in connection with claims arising under this Agreement or the Transaction, each Party hereto irrevocably and unconditionally (i) submits to the exclusive jurisdiction of the Chosen Courts, (ii) agrees not to commence any such Proceeding except in such courts, (iii) waives, to the fullest extent it may legally and effectively do so, any objection which it may now or hereafter have to the laying of venue of any such Proceeding in the Chosen Courts, (iv) waives, to the fullest extent permitted by law, the defense of an inconvenient forum to the maintenance of such Proceeding and (v) agrees that service of process upon such Party in any such Proceeding shall be effective if notice is given in accordance with Section 6.1 of this Agreement. Nothing in this Agreement will affect the right of any Party to serve process in any other manner permitted by Law.  Each of the Parties agrees that a final judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law.  EACH PARTY HERETO IRREVOCABLY WAIVES ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTION.  Notwithstanding anything herein to the contrary, the Parties agree that this Section 6.5(b) shall not apply to any Proceeding which is the subject of a demand for arbitration under Section 6.5(c).

16

(c)                                  Arbitration.

(i)                                     Each Party hereby agrees that any dispute, claim or controversies arising out of or related to this Agreement or the Transaction (all of which are referred to as “Disputes”) shall, on the demand of any party thereto, be resolved through binding and final arbitration in accordance with the Commercial Arbitration Rules (the “Rules”) of the American Arbitration Association (“AAA”) then in effect, except as those Rules may be modified in this Section 6.5(c).

(ii)                                  There shall be three (3) arbitrators.  If there are only two (2) parties to the Dispute, each party shall select one arbitrator within fifteen (15) days after receipt by respondent of a copy of the demand for arbitration.  Such arbitrators may be affiliated or interested persons of such parties.  If there are more than two (2) parties to the Dispute, all claimants, on the one hand, and all respondents, on the other hand, shall each select, by the vote of a majority of the claimants or the respondents, as the case may be, one arbitrator within fifteen (15) days after receipt of a demand for arbitration. Such arbitrators may be affiliated or interested persons of the claimants or the respondents, as the case may be.  If either a claimant (or all claimants) or a respondent (or all respondents) fail to timely select an arbitrator then the party (or parties) who has selected an arbitrator may request AAA to provide a list of three (3) proposed arbitrators in accordance with the Rules (each of whom shall be neutral, impartial and unaffiliated with any party) and the party (or parties) that failed to timely appoint an arbitrator shall have ten (10) days from the date AAA provides such list to select one of the three arbitrators proposed by AAA.  If such party (or parties) fail to select such arbitrator by such time, the party (or parties) who have appointed the first (1st) arbitrator shall then have ten (10) days to select one of the three (3) arbitrators proposed by AAA to be the second (2nd) arbitrator; and if he/they should fail to select the second (2nd) arbitrator by such time, AAA shall select, within fifteen (15) days thereafter, one (1) of the three (3) arbitrators it had proposed as the second (2nd) arbitrator.  The two (2) arbitrators so appointed shall jointly appoint the third and presiding arbitrator (who shall be neutral, impartial and unaffiliated with any party) within fifteen (15) days of the appointment of the second (2nd) arbitrator.  If the third (3rd) arbitrator has not been appointed within the time limit specified herein, then AAA shall provide a list of proposed arbitrators in accordance with the Rules, and the arbitrator shall be appointed by AAA in accordance with a listing, striking and ranking procedure, with each party having a limited number of strikes, excluding strikes for cause.

(iii)                               The place of arbitration shall be Boston, Massachusetts unless otherwise agreed by the parties.  There shall be only limited documentary discovery of documents directly related to the issues in dispute, as may be ordered by the arbitrators.

(iv)                              In rendering an award or decision (the “Award”), the arbitrators shall be required to follow the Laws of the State of Maryland.  Any arbitration proceedings or Award rendered hereunder and the validity, effect and interpretation of this arbitration agreement shall be governed by the Federal Arbitration Act, 9 U.S.C. §1 et seq.  The Award shall be in writing and may, but shall not be required to briefly state the findings of fact and conclusions of law on which it is based.  Any monetary award shall be made and payable in United States Dollars free of any tax, deduction or offset.  The party against which the Award assesses a monetary obligation shall pay that obligation on or

17

before the thirtieth (30th) day following the date of the Award or such other date as the Award may provide.

(v)                                 Except as otherwise agreed by the parties thereto, each party involved in a Dispute shall bear its own costs and expenses (including attorneys’ fees), and the arbitrators shall not render an award that would include shifting of any such costs or expenses (including attorneys’ fees).  Each party (or, if there are more than two (2) parties to the Dispute, all claimants, on the one hand, and all respondents, on the other hand, respectively) shall bear the costs and expenses of its (or their) selected arbitrator and the parties (or, if there are more than two (2) parties to the Dispute, all claimants, on the one hand, and all respondents, on the other hand) shall equally bear the costs and expenses of the third (3rd) appointed arbitrator.

(vi)                              An Award shall be final and binding upon the parties thereto and shall be the sole and exclusive remedy between such parties relating to the Dispute, including any claims, counterclaims, issues or accounting presented to the arbitrators.  Judgment upon the Award may be entered in any court having jurisdiction.  To the fullest extent permitted by Law, no application or appeal to any court of competent jurisdiction may be made in connection with any question of law arising in the course of arbitration or with respect to any award made except for actions relating to enforcement of this agreement to arbitrate or any arbitral award issued hereunder and except for actions seeking interim or other provisional relief in aid of arbitration proceedings in any court of competent jurisdiction.

Section 6.6                                    Severability.  If at any time subsequent to the date hereof, any provision of this Agreement is determined by any court or arbitrator of competent jurisdiction to be invalid, illegal or unenforceable in any respect, such provision will be enforced to the maximum extent possible given the intent of the Parties.  If such clause or provision cannot be so enforced, such provision shall be stricken from this Agreement and the remainder of this Agreement shall be enforced as if such invalid, illegal or unenforceable clause or provision had (to the extent not enforceable) never been contained in this Agreement.  Notwithstanding the forgoing, if the value of this Agreement based upon the substantial benefit of the bargain for any Party is materially impaired, which determination as made by the presiding court or arbitrator of competent jurisdiction shall be binding, then the Parties agree to substitute such provision(s) through good faith negotiations.

Section 6.7                                    Counterparts.  This Agreement may be executed in any number of counterparts, all of which shall be considered one and the same agreement and shall become effective when counterparts have been signed by each of the Parties and delivered to the other Party (including via facsimile or other electronic transmission), it being understood that each Party need not sign the same counterpart.

Section 6.8                                    Expenses.  Each Party shall bear its own expenses incurred or to be incurred in connection with the negotiation and execution of this Agreement and each other agreement, document and instrument contemplated by this Agreement and the consummation of the Transaction.

18

Section 6.9                                    Waivers and Amendments.  This Agreement may be amended, modified, superseded, cancelled, renewed or extended, and the terms and conditions of this Agreement may be waived, only by a written instrument signed by the Parties or, in the case of a waiver, by the Party waiving compliance.  No delay on the part of any Party in exercising any right, power or privilege pursuant to this Agreement shall operate as a waiver thereof, nor shall any waiver of the part of any Party of any right, power or privilege pursuant to this Agreement, nor shall any single or partial exercise of any right, power or privilege pursuant to this Agreement, preclude any other or further exercise thereof or the exercise of any other right, power or privilege pursuant to this Agreement.  The rights and remedies provided pursuant to this Agreement are cumulative and are not exclusive of any rights or remedies which any Party otherwise may have at Law or in equity.

Section 6.10                             Certain Remedies.

(a)                                 Specific Performance.  The Parties agree that irreparable damage would occur in the event that any of the provisions of this Agreement or of any other agreement between them with respect to the Transaction were not performed in accordance with their specific terms or were otherwise breached. It is accordingly agreed that, in addition to any other applicable remedies at Law or equity, the Parties and each intended third party beneficiary of this Agreement shall be entitled to an injunction or injunctions, without proof of damages, to prevent breaches of this Agreement or of any other agreement between them with respect to the Transaction and to enforce specifically the terms and provisions of this Agreement.

(b)                                 No Consequential Damages.  To the fullest extent permitted by applicable Law, the Parties shall not assert, and hereby waive, any claim or any such damages, whether or not accrued and whether or not known or suspected to exist in its favor, against any other Party and its respective Affiliates, members, members’ affiliates, officers, directors, partners, trustees, employees, attorneys and agents on any theory of liability, for special, indirect, consequential or punitive damages (as opposed to direct or actual damages) (whether or not the claim therefor is based on Contract, tort or duty imposed by any applicable legal requirement) arising out of, in connection with, or as a result of, this Agreement or of any other agreement between them with respect to the Transaction.
