No stop order suspending the effectiveness of such registration statement has been issued, and no proceeding for that purpose has been instituted or, to the knowledge of the Company, threatened by the Commission. Additionally, the Company is eligible to file a new registration statement on Form S-3 with respect to the Common Stock that will become effective upon filing with the Commission pursuant to Rule 462(e) under the Act.

          (b) Each part of the Registration Statement, when such part became or becomes effective, and the Prospectus and any amendment or supplement thereto, on the date of

filing thereof with the Commission and at each Settlement Date (as hereinafter defined), conformed or will conform in all material respects with the requirements of the Act and the Rules and Regulations; each part of the Registration Statement, when such part became or becomes effective, did not or will not contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading; and the Prospectus and any amendment or supplement thereto, on the date of filing thereof with the Commission and at each Settlement Date, did not or will not include an untrue statement of a material fact or omit to state a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading; except that the foregoing shall not apply to statements in or omissions from any such document in reliance upon, and in conformity with, written information furnished to the Company by or on behalf of the Sales Manager, specifically for use in the Registration Statement, the Prospectus or any amendment or supplement thereto.

          (z) The Company has met the qualification requirements for a “real estate investment trust” during its taxable years ending on or after December 31, 1999 and its proposed method of operations will enable it to continue to meet the requirements for qualification and taxation as a “real estate investment trust” under the Internal Revenue Code of 1986, as amended (the “Code”), assuming no change in the applicable underlying law.

ARTICLE II

SALE AND DELIVERY OF SECURITIES

     2.1 (a) On the basis of the representations, warranties and agreements herein contained, but subject to the terms and conditions herein set forth, the Company agrees to issue and sell through the Sales Manager, as agent, and the Sales Manager agrees to sell, as agent for the Company, on a best efforts basis, shares of the Common Stock during the term of this Agreement on the terms set forth herein. The Common Stock will be sold from time to time as described in the Registration Statement and Prospectus, in amounts and, subject to price limitations, at prices as directed by the Company and as agreed to by the Sales Manager; provided that nothing in this Agreement shall be construed to require the Company to sell any shares of Common Stock through the Sales Manager.

          (b) The Company or the Sales Manager may, upon notice to the other party hereto by telephone (confirmed promptly by telecopy or e-mail), at any time and from time to time suspend the offering of Common Stock; provided, however, that such suspension shall not affect or impair the parties’ respective obligations with respect to the Common Stock sold hereunder prior to the giving of such notice.

          (c) The compensation to the Sales Manager for sales of Common Stock sold under this Agreement shall be at the following commission rates: 3.0% of the gross sales price per share (“sales proceeds”) for the first $8 million of aggregate sales proceeds raised in each Sales Period; 2.5% of sales proceeds for the next $4 million of aggregate sales proceeds raised in each Sales Period and 2.0% of sales proceeds for any additional aggregate sales proceeds raised in each Sales Period. For purposes of this section 2.1(c), the initial “Sales Period” shall commence on March 10, 2008 and shall end on December 31, 2009 and each subsequent Sales Period shall be for a two year period, commencing on January 1 and ending on December 31 of the following calendar year. The remaining proceeds, after further deduction for any transaction fees imposed by any governmental or self-regulatory organization in respect to such sale shall constitute the net proceeds to the Company for such Common Stock (the “Net Proceeds”). For purposes of the first sentence of this section 2.1(c), sales proceeds include sales proceeds from sales of Common Stock by the Sales Manager for the account of the Company, whether under this Agreement, or otherwise.

          (d) The Company shall open and maintain a trading account (the “Trading Account”) at a clearing agent designated by the Sales Manager to facilitate the transactions contemplated by this Agreement. The Net Proceeds from the sale of the Common Stock shall be available in the Trading Account on the third business day (or such other day as is industry practice for regular-way trading) following each sale of the Common Stock (each, a “Settlement Date”). The Company shall effect the delivery of the applicable number of shares of Common Stock to an account designated by the Sales Manager at The Depository Trust Company on or before the Settlement Date of each sale hereunder. The Sales Manager’s compensation shall be withheld from the sales proceeds on each Settlement Date and shall be paid to the Sales Manager.

          (e) At each Settlement Date, the Company shall be deemed to have affirmed each representation, warranty, covenant and other agreement contained in this Agreement. Any obligation of the Sales Manager under this Agreement shall be subject to the continuing accuracy of the representations and warranties of the Company herein, to the performance by the Company of its obligations hereunder and to the continuing satisfaction of the additional conditions specified in Article IV of this Agreement.

          (f) If the Company shall default on its obligation to deliver Common Stock on any Settlement Date, the Company shall (i) hold the Sales Manager harmless against any loss, claim or damage arising from or as a result of such default by the Company and (ii) pay the Sales Manager any commission to which it would otherwise be entitled absent such default.

ARTICLE III

COVENANTS OF THE COMPANY

     3.1 The Company covenants and agrees with the Sales Manager that:

          (a) As promptly as practicable after the date of this Agreement, the Company will (if not previously filed) file the Registration Statement to permit sales of the Common Stock under the Act. The Company will use its best reasonable efforts to cause the Registration Statement to become effective as promptly as possible thereafter.

          (b) During the period in which the Sales Agent has been requested to offer and sell Common Stock, the Company will notify the Sales Manager promptly of the time when any subsequent amendment to the Registration Statement has become effective or any subsequent supplement to the Prospectus has been filed and of any request by the Commission for any amendment or supplement to the Registration Statement or the Prospectus or for additional information. The Company will prepare and file with the Commission, promptly upon the Sales Manager’s reasonable request, any amendments or supplements to the Registration Statement or Prospectus that, in the Sales Manager’s reasonable opinion, may be necessary or advisable in connection with the sale of the Common Stock pursuant to this Agreement. The Company will not file any amendment or supplement to the Registration Statement or Prospectus (other than a supplement to the Prospectus that (i) does not materially change the information about the Company or its business, operations, properties or financial condition previously disclosed in the Registration Statement or Prospectus, (ii) relates to a “follow-on” offering of the Common Stock by the Company, or (iii) relates to an offering of securities other than the Common Stock (each, an “Excluded Supplement”)) unless a copy thereof has been submitted to the Sales Manager a reasonable period of time before the filing and the Sales Manager has not reasonably objected thereto; and it will notify the Sales Manager at the time of filing thereof of any document that upon filing is deemed to be incorporated by reference in the Registration Statement or Prospectus, which will then be available on the Company’s website at ▇▇▇.▇▇▇▇▇▇▇▇.▇▇▇ (and will furnish to the Sales Manager any such document that is not available on the Company’s website). The Company will cause each amendment to the Registration Statement or supplement to the Prospectus and each filing or report incorporated therein, to be prepared in form and substance as required by the Act, the Rules and Regulations, the Exchange Act and the rules and regulations thereunder, and to be timely filed with the Commission.

          (c) The Company will advise the Sales Manager, promptly after it shall receive notice or obtain knowledge thereof, of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement, of the suspension of the qualification of the Common Stock for offering or sale in any jurisdiction, or of the initiation or threatening of any proceeding for any such purpose; and it will promptly use its best reasonable efforts to prevent the issuance of any stop order or to obtain its withdrawal if such a stop order should be issued.

          (d) Within the time during which a prospectus relating to the Common Stock is required to be delivered under the Act, the Company will comply with all requirements

imposed upon it by the Act and by the Rules and Regulations, as from time to time in force, so far as necessary to permit the continuance of sales of or dealings in the Common Stock as contemplated by the provisions hereof and the Prospectus. If during such period any event occurs as a result of which the Prospectus, as then amended or supplemented, would include an untrue statement of a material fact or omit to state a material fact necessary to make the statements therein, in the light of the circumstances then existing, not misleading, or if during such period it is necessary to amend or supplement the Registration Statement or Prospectus to comply with the Act, the Company will promptly notify the Sales Manager to suspend the offering of Common Stock during such period and the Company will amend or supplement the Registration Statement or Prospectus (at the expense of the Company) so as to correct such statement or omission or effect such compliance and will use its best reasonable efforts to have any amendment or supplement to the Registration Statement or Prospectus declared effective as soon as possible, unless the Company has reasonable business reasons to defer public disclosure of the relevant information.

          (e) The Company will use its best reasonable efforts to qualify the Common Stock for sale under the securities laws of such jurisdictions as the Sales Manager designates and to continue such qualifications in effect so long as required for the sale of the Common Stock, except that the Company shall not be required in connection therewith to qualify as a foreign corporation or to execute a general consent to service of process in any jurisdiction.

          (f) The Company will furnish to the Sales Manager and its legal counsel (at the expense of the Company) copies of the Registration Statement, the Prospectus (including all documents incorporated by reference therein) and all amendments and supplements to the Registration Statement or Prospectus that are filed with the Commission during the period in which a prospectus relating to the Common Stock is required to be delivered under the Act (including all documents filed with the Commission during such period that are deemed to be incorporated by reference therein), in each case as soon as available and in such quantities as the Sales Manager may from time to time reasonably request. The Company will take such action as to enable the conditions set forth in Rule 153(b) of the Rules and Regulations to be satisfied at all times that the Sales Agent is selling Common Stock.

          (g) The Company will make generally available to its security holders as soon as practicable, but in any event not later than 15 months after the end of the Company’s current fiscal quarter, an earnings statement (which need not be audited) covering a 12-month period that satisfies the provisions of Section 11(a) of the Act and Rule 158 of the Rules and Regulations.

          (h) The Company, whether or not the transactions contemplated hereunder are consummated or this Agreement is terminated, will pay all of its expenses incident to the performance of its obligations hereunder (including, but not limited to, any transaction fees imposed by any governmental or self-regulatory organization with respect to transactions contemplated by this Agreement and any blue sky fees) and will pay the expenses of printing all documents relating to the offering. The Company will reimburse the Sales Manager for its reasonable out-of-pocket costs and expenses incurred in connection with entering into this Agreement, including, without limitation, reasonable travel, reproduction, printing and similar expenses, as well as the reasonable fees and disbursements of its legal counsel.

          (i) The Company shall use its best reasonable efforts to list, subject to notice of issuance, the Common Stock on the applicable Trading Market.

          (j) The Company will apply the Net Proceeds from the sale of the Stock as set forth in the Prospectus.

          (k) The Company will not, directly or indirectly, offer or sell any shares of common stock (other than the Common Stock) or securities convertible into or exchangeable for, or any rights to purchase or acquire, common stock during the period from the date of this Agreement through the final Settlement Date for the sale of Common Stock hereunder without (i) giving the Sales Manager at least one business day prior written notice specifying the nature of the proposed sale and the date of such proposed sale and (ii) suspending activity under this program for such period of time as may reasonably be determined by agreement of the Company and the Sales Manager; provided, however, that no such notice and suspension shall be required in connection with the Company’s issuance or sale of (i) shares of common stock pursuant to any employee or director stock option or benefits plan, stock ownership plan, dividend reinvestment plan, as such plans may be amended from time to time, and (ii) common stock issuable upon conversion of securities or the exercise of warrants, options or other rights in effect or outstanding on the date hereof. Notwithstanding the foregoing, this paragraph (k) shall not apply during periods that the Company is neither selling Common Stock through the Sales Manager nor has requested the Sales Manager to sell Common Stock.

          (l) The Company will, at any time during the term of this Agreement, as supplemented from time to time, advise the Sales Manager immediately after it shall have received notice or obtain knowledge thereof, of any information or fact that would alter or affect any opinion, certificate, letter and other document provided to the Sales Manager pursuant to Article IV herein.

          (m) Each time that the Registration Statement or the Prospectus shall be amended or supplemented (other than an Excluded Supplement) and on the dates specified in Section 4.1(f) below, the Company shall (unless the Company is not then selling Common Stock through the Sales Manager and has not requested the Sales Manager to sell Common Stock) furnish or cause to be furnished to the Sales Manager forthwith a certificate, in form and substance satisfactory to the Sales Manager to the effect that the statements contained in the certificates referred to in Section 4.1(f) below that were last furnished to the Sales Manager are true and correct at the time of such amendment or supplement, as the case may be, as though made at and as of such time (except that such statements shall be deemed to relate to the Registration Statement and the Prospectus as amended and supplemented to such time) or, in lieu of such certificates, certificates of the same tenor as the certificates referred to in said Section 4.1(f) below, modified as necessary to relate to the Registration Statement and the Prospectus as amended and supplemented to the time of delivery of such certificate.

          (n) Each time that a post-effective amendment to the Registration Statement is declared effective or the Company files an Annual Report on Form 10-K, and at such other times as may be reasonably requested by the Sales Manager, the Company shall (unless the Company is not then selling Common Stock through the Sales Manager and has not requested the Sales Manager to sell Common Stock) furnish or cause to be furnished forthwith to the Sales Manager

and to its legal counsel, a written opinion of ▇▇▇▇▇▇▇ ▇▇▇▇▇ LLP, counsel to the Company (“Company Counsel”), or other counsel reasonably satisfactory to the Sales Manager, dated the date of effectiveness of such amendment or the date of filing with the Commission of such document, as the case may be, in form and substance satisfactory to the Sales Manager, of the same tenor as the opinion referred to in Section 4.1(d) below, but modified as necessary to relate to the Registration Statement and the Prospectus as amended and supplemented to the time of delivery of such opinion; provided , however that in lieu of such opinion, the Company may furnish the Sales Manager with a letter from Company Counsel to the effect that the Sales Manager may rely on the prior opinion delivered pursuant to Section 4.1(d) below to the same extent as if it were dated the date of such letter (except that statements in such prior opinion shall be deemed to relate to the Registration Statement and the Prospectus as amended or supplemented to the time of delivery of such letter).

          (o) Each time that a post-effective amendment to the Registration Statement is declared effective or the Company files an Annual Report on Form 10-K, and at such other times as may be reasonably requested by the Sales Manager, the Company shall (unless the Company is not then selling Common Stock through the Sales Manager and has not requested the Sales Manager to sell Common Stock) cause Ernst & Young LLP, or other independent accountants then retained by the Company, forthwith to furnish to the Sales Manager a letter, dated the date of effectiveness of such amendment, or the date of filing of such supplement or other document with the Commission, as the case may be, in form and substance satisfactory to the Sales Manager, of the same tenor as the letter referred to in Section 4.1(e) below but modified to relate to the Registration Statement and the Prospectus, as amended and supplemented to the date of such letter.

          (p) The Company represents and agrees that, unless it obtains the prior consent of the Sales Manager, and the Sales Manager represents and agrees that, unless it obtains the prior consent of the Company, it has not made and will not make any offer relating to the Common Stock that would constitute an Issuer Free Writing Prospectus, or that would otherwise constitute a “free writing prospectus” as defined in Rule 405, required to be filed with the Commission. Any such free writing prospectus consented to by the Company and the Sales Manager is hereinafter referred to as a “Permitted Free Writing Prospectus.” The Company represents that it has treated and agrees that it will treat each Permitted Free Writing Prospectus as an “issuer free writing prospectus,” as defined in Rule 433 of the Act, and has complied and will comply with the requirements of Rules 164 and 433 of the Act, as applicable to any Permitted Free Writing Prospectus, including timely Commission filings where required, legending and record keeping.

     For the purposes of this Section, “Issuer Free Writing Prospectus” means any “issuer free writing prospectus,” as defined in Rule 433 of the Act, relating to the Common Stock in the form filed or required to be filed with the Commission or, if not required to be filed, in the form retained in the Company’s records pursuant to Rule 433(g) of the Act.

     Notwithstanding the foregoing, the Company shall not be required to obtain the consent of the Sales Manager with respect to the offering of any securities other than Common Stock or any “follow-on” offering of Common Stock pursuant to an Issuer Free Writing Prospectus.

          (i) The representations and warranties of the Company in this Agreement are true and correct, as if made at and as of the Commencement Date or the Certificate Date (as the case may be), and the Company has complied with all the agreements and satisfied all the conditions on its part to be performed or satisfied at or prior to the Commencement Date and each such Certificate Date (as the case may be);

ARTICLE V

INDEMNIFICATION AND CONTRIBUTION

     5.1 (a) The Company agrees to indemnify and hold harmless the Sales Manager and each person, if any, who controls the Sales Manager within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, as follows:

          (i) against any and all loss, liability, claim, damage and expense whatsoever, as incurred, arising out of any untrue statement or alleged untrue statement of a material fact contained in the representations in this Agreement or contained in the Registration Statement (or any amendment thereto), or the omission or alleged omission therefrom of a material fact required to be stated therein or necessary to make the statements therein not misleading or arising out of any untrue statement or alleged untrue statement of a material fact contained in any preliminary prospectus or the Prospectus (or any amendment or supplement thereto) or the omission or alleged omission therefrom of a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading;

          (ii) against any and all loss, liability, claim, damage and expense whatsoever, as incurred, to the extent of the aggregate amount paid in settlement of any litigation, or any investigation or proceeding by any governmental agency or body, 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; and

          (iii) against any and all expense whatsoever, as incurred (including, subject to Section 5(c) hereof, the reasonable fees and disbursements of legal counsel chosen by the Sales Manager), reasonably incurred 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 statement or omission, or any such alleged untrue statement or omission, to the extent that any such expense is not paid under (i) or (ii) above;

provided, however, that this indemnity agreement shall not apply to any loss, liability, claim, damage or expense to the extent arising out of any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with written information furnished to the Company by the Sales Manager expressly for use in the Registration Statement (or any amendment thereto) or any preliminary prospectus or the Prospectus (or any amendment or supplement thereto).

          (b) The Sales Manager agrees to indemnify and hold harmless the Company and its directors and each officer of the Company who signed the Registration Statement, and each person, if any, who controls the Company within the meaning of Section 15 of the Act or Section 20 of the Exchange Act against any and all loss, liability, claim, damage and expense described in the indemnity contained in Section 5.1(a), as incurred, but only with respect to untrue statements or omissions, or alleged untrue statements or omissions, made in the Registration Statement (or any amendments thereto) or any preliminary prospectus or the Prospectus (or any amendment or supplement thereto) in reliance upon and in conformity with written information furnished to the Company by the Sales Manager expressly for use in the Registration Statement (or any amendment thereto) or such preliminary prospectus or the Prospectus (or any amendment or supplement thereto). The total liability of the Sales Manager under this Section 5.1(b) shall not exceed the total actual sales price of Common Stock sold by the Sales Manager that is the subject of the dispute.

          (c) Any indemnified party that proposes to assert the right to be indemnified under this Article V will, promptly after receipt of notice of commencement of any action against such party in respect of which a claim is to be made against an indemnifying party or parties under this Article V, notify each such indemnifying party of the commencement of such action, enclosing a copy of all papers served, but the omission so to notify such indemnifying party will not relieve the indemnifying party from any liability that it might have to any indemnified party to the extent it is not materially prejudiced as a result thereof. If any such action is brought against any indemnified party and it notifies the indemnifying party of its commencement, the indemnifying party will be entitled to participate in and, to the extent that it elects by delivering written notice to the indemnified party promptly after receiving notice of the commencement of the action from the indemnified party, jointly with any other indemnifying party similarly notified, to assume the defense of the action, with legal counsel reasonably satisfactory to the indemnified party, and after notice from the indemnifying party to the indemnified party of its election to assume the defense, the indemnifying party will not be liable to the indemnified party for any legal or other expenses except as provided below and except for the reasonable costs of investigation subsequently incurred by the indemnified party in connection with the defense. The indemnified party will have the right to employ its own legal counsel in any such action, but the fees, expenses and other charges of such legal counsel will be at the expense of such indemnified party unless (1) the employment of legal counsel by the indemnified party has been authorized in writing by the indemnifying party, (2) the indemnified party has reasonably concluded (based on written advice of legal counsel) that there may be legal defenses available to it or other indemnified parties that are different from or in addition to those available to the indemnifying party, (3) a conflict or potential conflict exists (based on written advice of legal counsel to the indemnified party) between the indemnified party and the indemnifying party (in which case the indemnifying party will not have the right to direct the defense of such action on behalf of the indemnified party) or (4) the indemnifying party has not in fact employed legal counsel to assume the defense of such action within a reasonable time after receiving notice of the commencement of the action, in each of which cases the reasonable fees, disbursements and other charges of legal counsel will be at the expense of the indemnifying party or parties. It is understood that the indemnifying party or parties shall not, in connection with any proceeding or related proceedings in the same jurisdiction, be liable for the reasonable fees, disbursements and other charges of more than one separate firm admitted to practice in such jurisdiction at any one time for all such indemnified party or parties. All such fees, disbursements and other charges will be reimbursed by the indemnifying party promptly as they are incurred. An indemnifying party will not be liable for any settlement of any action or claim effected without its written consent (which consent will not be unreasonably withheld).

          (d) In order to provide for just and equitable contribution in circumstances in which the indemnification provided for in the foregoing paragraphs of this Article V is applicable in accordance with its terms but for any reason is held to be unavailable from the Company or the Sales Manager, the Company and the Sales Manager will contribute to the total losses, claims, liabilities, expenses and damages (including any investigative, legal and other expenses reasonably incurred in connection with, and any amount paid in settlement of, any action, suit or proceeding or any claim asserted, but after deducting any contribution received by the Company from persons other than the Sales Manager, such as persons who control the Company within the meaning of the Act, officers of the Company who signed the Registration Statement and directors of the Company, who also may be liable for contribution) to which the

Company and the Sales Manager may be subject in such proportion as shall be appropriate to reflect the relative benefits received by the Company on the one hand and the Sales Manager on the other. The relative benefits received by the Company on the one hand and the Sales Manager on the other hand shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting expenses) received by the Company bear to the total compensation (before deducting expenses) received by the Sales Manager from the sale of Common Stock on behalf of the Company. If, but only if, the allocation provided by the foregoing sentence is not permitted by applicable law, the allocation of contribution shall be made in such proportion as is appropriate to reflect not only the relative benefits referred to in the foregoing sentence but also the relative fault of the Company, on the one hand, and the Sales Manager, on the other, with respect to the statements or omission which resulted in such loss, claim, liability, expense or damage, or action in respect thereof, as well as any other relevant equitable considerations with respect to such offering. Such relative fault shall be determined by reference to whether the untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Company or the Sales Manager, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company and the Sales Manager agree that it would not be just and equitable if contributions pursuant to this Section 5.1(d) were to be determined by pro rata allocation or by any other method of allocation which does not take into account the equitable considerations referred to herein. The amount paid or payable by an indemnified party as a result of the loss, claim, liability, expense or damage, or action in respect thereof, referred to above in this Section 5.1(d) shall be deemed to include, for the purpose of this Section 5.1(d), any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the foregoing provisions of this Section 5.1(d), the Sales Manager shall not be required to contribute any amount in excess of the amount by which the total actual sales price at which Common Stock sold by the Sales Manager exceeds the amount of any damages that the Sales Manager has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission and no person found guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) will be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of this Section 5.1(d), any person who controls a party to this Agreement within the meaning of the Act will have the same rights to contribution as that party, and each officer and director of the Company who signed the Registration Statement will have the same rights to contribution as the Company, subject in each case to the provisions hereof. Any party entitled to contribution, promptly after receipt of notice of commencement of any action against such party in respect of which a claim for contribution may be made under this Section 5.1(d), will notify any such party or parties from whom contribution may be sought, but the omission so to notify will not relieve that party or parties from whom contribution may be sought from any other obligation it or they may have under this Section 5.1(d). No party will be liable for contribution with respect to any action or claim settled without its written consent (which consent will not be unreasonably withheld).

          (e) The indemnity and contribution provided by this Article V shall not relieve the Company and the Sales Manager from any liability the Company and the Sales Manager may otherwise have (including, without limitation, any liability the Sales Manager may have for a breach of its obligations under Article II hereof).

     7.4 Any termination of this Agreement shall be effective on the date specified in such notice of termination; provided that such termination shall not be effective until the close of business on the date of receipt of such notice by the Sales Manager or the Company, as the case may be.
