Section 1 - Registrant’s Business and Operations

Item 1.01. Entry into a Material Definitive Agreement.

On June 22, 2007, Sentra Consulting Corp. (the “Company”) agreed to loan funds to Karat Platinum, LLC (“KP”), a company which manufactures and sells a platinum alloy and platinum jewelry. Pursuant to the terms of the Promissory Note executed by KP to the Company, the outstanding principal and accrued interest at the rate of 1.5% per month shall be due and payable September 22, 2007. The Company has currently loaned KP $150,000 and may advance additional sums to KP. If KP does not pay said amount when due, interest shall accrue on the outstanding principal amount at the rate of 2% per month thereafter. KP has the right to prepay the Notes without penalty or premium.

The loan was made in connection with the execution of the Letter of Intent between KP and the Company described below.

For all the terms and conditions of the Note issued by KP to the Company, reference is hereby made to such note annexed hereto as Exhibit 10.3. All statements made herein concerning the foregoing are qualified by reference to said exhibit.

Section 2 - Financial Information

Item 2.03. Creation of a Direct Financial Obligation or an Obligation under an Off-Balance Sheet Arrangement of a Registrant.

On each of June 22nd, 25^th and 26th, 2007, Sentra Consulting Corp. (the “Company”) issued promissory notes (the “Notes”) to three persons who are minority shareholders of the Company (the “Noteholders”), in the original principal amounts of $100,000, $50,000 and $450,000, respectively, in consideration for loans made simultaneously therewith by each of the three Noteholders. Principal and interest, which accrues at 1.5% per month, are due and payable by the Company 90 days after the date of each of the Notes. If the Company does not pay said amount when due, interest shall accrue on the outstanding principal amount at the rate of 2% per month thereafter. The Company has the right to prepay the Notes without penalty or premium. Each of the Notes are secured by a guaranty of payment by a principal of KP.

As additional consideration for issuance of the Notes, the Company entered into Warrant Agreements with the Noteholders, whereby the Company issued an aggregate of 60,000 common stock purchase warrants. Each common stock purchase warrant grants the holder thereof the right to purchase one share of common stock of the Company at an exercise price of $0.50 per share for a term of 3 years; said term to commence 6 months from the date of each Note. The Warrant Agreements provide that under certain issuances by the Company of additional equity securities for a consideration per share less than $0.50 (the exercise price of the common stock purchase warrants), the exercise price of the warrants shall be reduced to such price.

For all the terms and conditions of the Notes and Warrant Agreements, reference is hereby made to the form of such notes and agreements annexed hereto as Exhibits 4.1 and 4.2, respectively. All statements made herein concerning the foregoing are qualified by reference to said exhibits.

Section 8 - Other Events

Item 8.01. Other Events.

On June 21, 2007, the Company entered into a non-binding Letter of Intent (the “LOI”) with KP pursuant to which the Company would purchase all the outstanding membership interests of KP in consideration for the issuance of 30,000,000 shares of the Company’s common stock and 500,000 common stock purchase warrants, each of which will provide the holder thereof the right to purchase one share of common stock of the Company for $0.01. The warrants will expire 10 years after the issuance thereof. The closing of the transaction contemplated by the LOI is subject to the satisfaction of certain conditions, including without limitation, the consent from the lenders to KP of the transaction with the Company and/or the release of the collateral of KP satisfactory to the Company, the completion of the due diligence investigation of both parties, the making of loans by the Company to KP in an amount of not less than $1,000,000, the delivery of any required consents from third parties and the delivery of audited financial statements of KP. Pursuant to the terms of the LOI, the Company and KP agreed to use their best efforts to negotiate and agree to a mutually acceptable definitive agreement within 120 days. If there is a closing, each of the Company and KP will have the right to appoint 2 members to the Board of Directors of the Company and said members shall appoint a fifth member.

KP further agreed that it will not directly or indirectly solicit, negotiate, or accept any offer from a third party to acquire any of KP’s assets or securities until October 21, 2007. KP also agreed to permit the Company and its representatives to begin its due diligence investigation and to have access to and inspect KP’s records, properties, personnel, and other such matters.

For all the terms and conditions of the LOI, reference is hereby made to such agreement annexed hereto as Exhibit 10.4. All statements made herein concerning the foregoing agreement are qualified by reference to said exhibit.

c.Any representation or warranty made by Maker under this Note shall be untrue or misleading in any material respect when made.

d.Maker shall have breached any of its covenants and agreements hereunder.

then, in each case where an Event of Default occurs, the Payee, by notice in writing to Maker shall inform Maker of such Event of Default and if such default is not cured within sixty business days from the date such notice is received by Maker, then Payee, may, at its option, declare the outstanding Principal Amount to be due and payable immediately, and upon any such declaration the same shall become immediately due and payable.

2.Representations of Payee.The Payee hereby acknowledges, represents and warrants to, and agrees with, the Maker as follows:

a. The Payee is executing the transactions contemplated by this Note and the Warrant Agreement dated the date hereof between the Maker and Payee (the “Warrant Agreement”; capitalized terms used herein not otherwise defined shall have the meanings ascribed to such terms in the Warrant Agreement), for his own account as principal, not as a nominee or agent, for investment purposes only, and not with a view to, or for, resale, distribution, or fractionalization thereof, in whole or in part, and no other person has a direct or indirect beneficial interest in this Note, the Warrants or the Warrant Shares or any portion thereof.

b. The Payee is not investing in the Securities as a result of, or subsequent to, any advertisement, article, notice, or other communication published in any newspaper, magazine or similar media or broadcast over television or radio, or presented at any seminar or meeting, or any solicitation of a subscription by a person other than the officers of the Maker.

c. Payee understands that the Securities have not been registered under the Securities Act of 1933, as amended (the “Securities Act”) or registered or qualified under any the securities laws of any state or other jurisdiction, and are “restricted securities,” and cannot be resold or otherwise transferred unless they are registered under the Securities Act, and registered or qualified under any other applicable securities laws, or an exemption from such registration and qualification is available.

d. Payee is an “accredited investor” as that term is defined in Rule 501 of the General Rules and Regulations under the Securities Act by reason of Rule 501(3).

e.

WARRANT AGREEMENT

WARRANT AGREEMENT (“Agreement”), dated as of June __, 2007, by and between Sentra Consulting Corp., a Nevada corporation (the “Company”), and ____________ (“Warrantholder”). Certain capitalized terms used herein are defined in Section 14 hereof.

In consideration of the mutual terms, conditions, representations, warranties and agreements herein set forth, and for other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, the parties hereto hereby agree as follows:

Section 1. Issuance of Warrants.

The Company hereby issues and grants to Warrantholder __________________ (________) stock purchase warrants (hereinafter referred to as “Warrants”). Each Warrant shall grant to the holder thereof the right to purchase one (1) share of common stock of the Company (the “Common Stock”). Commencing six (6) months from the date hereof (the “Warrant Commencement Date”), and terminating on _____________, 2010 (the “Warrant Expiration Date”), the holder shall have the right, subject to the satisfaction of the conditions to exercise set forth in Section 7 of this Agreement, to purchase one (1) share of Common Stock per each Warrant (the shares of Common Stock issuable upon exercise of the Warrants being collectively referred to herein as the “Warrant Shares”) at an exercise price of $.50 per Warrant Share (the “Exercise Price”). The number of Warrant Shares issuable on exercise of each Warrant and the Exercise Price are all subject to adjustment pursuant to Section 8 of this Agreement.

Section 2. Form of Warrant Certificates.

Promptly after the execution and delivery of this Agreement by the parties hereto, the Company may, in its sole and absolute discretion, cause to be executed and delivered to Warrantholder one or more certificates evidencing the Warrants (the “Warrant Certificates”). Each Warrant Certificate delivered hereunder shall be substantially in the form set forth in Exhibit A attached hereto, and may have such letters, numbers or other identification marks and legends, summaries or endorsements printed thereon as the Company may deem appropriate and that are not inconsistent with the terms of this Agreement or as may be required by applicable law, rule or regulation. Each Warrant Certificate shall be dated the date of execution by the Company.

Section 3. Execution of Warrant Certificates.

Each Warrant Certificate delivered hereunder shall be signed on behalf of the Company by at least one of the following: its Chief Executive Officer, President, Secretary or Treasurer. Each such signature may be in the form of a facsimile thereof and may be imprinted or otherwise reproduced on the Warrant Certificates.

If any officer of the Company who signed any Warrant Certificate ceases to be an officer of the Company before the Warrant Certificate so signed shall have been delivered by the Company, such Warrant Certificate nevertheless may be delivered as though such person had not ceased to be such officer of the Company.

Section 4. Registration of Ownership and Transfer.

Warrant Certificates shall be issued in registered form only. The Company will keep or cause to be kept books for registration of ownership and transfer of each Warrant Certificate issued pursuant to this Agreement. Each Warrant Certificate issued pursuant to this Agreement shall be numbered by the Company and shall be registered by the Company in the name of the holder thereof (initially the Warrantholder). The Company may deem and treat the registered holder of any Warrant Certificate as the absolute owner thereof (notwithstanding any notation of ownership or other writing thereon made by anyone) for the purpose of any exercise thereof and for all other purposes, and the Company shall not be affected by any notice to the contrary.

Section 5. No Transfers.

No Warrant may be sold, pledged, hypothecated, assigned, conveyed, transferred or otherwise disposed of without the agreement of the Company, which will not be unreasonably withheld.

Section 6. Mutilated or Missing Warrant Certificates.

If any Warrant Certificate is mutilated, lost, stolen or destroyed, the Company shall issue, upon surrender and cancellation of any mutilated Warrant Certificate, or in lieu of and substitution for any lost, stolen or destroyed Warrant Certificate, a new Warrant Certificate of like tenor and representing an equal number of Warrants. In the case of a lost, stolen or destroyed Warrant Certificate, a new Warrant Certificate shall be issued by the Company only upon the Company’s receipt of reasonably satisfactory evidence of such loss, theft or destruction and, if requested, an indemnity or bond reasonably satisfactory to the Company.

Section 7. Exercise of Warrants.

A.Exercise. Subject to the terms and conditions set forth in this Section 7, Warrants may be exercised, in whole or in part (but not as to any fractional part of a Warrant), at any time or from time to time on and after the Warrant Commencement Date and on or prior to 5:00 p.m., Eastern time, on the Warrant Expiration Date.

In order to exercise any Warrant, Warrantholder shall deliver to the Company at its office referred to in Section 15 the following: (i) a written notice in the form of the Election to Purchase appearing at the end of the form of Warrant Certificate attached as Exhibit B attached hereto, to Purchase hereto of such Warrantholder’s election to exercise the Warrants, which notice shall specify the number of such Warrantholder’s Warrants being exercised; (ii) the Warrant Certificate or Warrant Certificates, if any, evidencing the Warrants being exercised; and (iii) payment of the aggregate Exercise Price.

All rights of Warrantholder with respect to any Warrant that has not been exercised, on or prior to 5:00 p.m., Eastern time, on the Warrant Expiration Date shall immediately cease and such Warrants shall be automatically cancelled and void.

B.Payment of Exercise Price. Payment of the Exercise Price with respect to Warrants being exercised hereunder shall be made by the payment to the Company, in cash, by check or wire transfer, of an amount equal to the Exercise Price multiplied by the number of Warrants then being exercised.

C.Payment of Taxes. The Company shall be responsible for paying any and all issue, documentary, stamp or other taxes that may be payable in respect of any issuance or delivery of Warrant Shares on exercise of a Warrant. Notwithstanding anything contained herein to the contrary, the Warrantholder shall be responsible for all taxes that may be due and payable by the Warrantholder as a result of the issuance of this Warrant to the Warrantholder or as a result of the issuance of the Warrant Shares upon due exercise hereof.

- 2 -

D.Delivery of Warrant Shares. Upon receipt of the items referred to in Section 7A, the Company shall, as promptly as practicable, execute and deliver or cause to be executed and delivered, to or upon the written order of Warrantholder, and in the name of Warrantholder or Warrantholder’s designee, a stock certificate or stock certificates representing the number of Warrant Shares to be issued on exercise of the Warrant(s). The certificates issued to Warrantholder or its designee shall bear any restrictive legend required under applicable law, rule or regulation. The stock certificate or certificates so delivered shall be registered in the name of Warrantholder or such other name as shall be designated in said notice. A Warrant shall be deemed to have been exercised and such stock certificate or stock certificates shall be deemed to have been issued, and such holder or any other Person so designated to be named therein shall be deemed to have become a holder of record of such shares for all purposes, as of the date that such notice, together with payment of the aggregate Exercise Price and the Warrant Certificate or Warrant Certificates evidencing the Warrants to be exercised, is received by the Company as aforesaid. If the Warrants evidenced by any Warrant Certificate are exercised in part, the Company shall, at the time of delivery of the stock certificates, deliver to the holder thereof a new Warrant Certificate evidencing the Warrants that were not exercised or surrendered, which shall in all respects (other than as to the number of Warrants evidenced thereby) be identical to the Warrant Certificate being exercised. Any Warrant Certificates surrendered upon exercise of Warrants shall be canceled by the Company.

Section 8. Adjustment of Number of Warrant Shares Issuable Upon Exercise of a Warrant and Adjustment of Exercise Price.

A.Adjustment for Stock Splits, Stock Dividends, Recapitalizations. The number of Warrant Shares issuable upon exercise of each Warrant and the Exercise Price shall each be proportionately adjusted to reflect any stock dividend, stock split, reverse stock split, recapitalization or the like affecting the number of outstanding shares of Common Stock that occurs after the date hereof.

B.Adjustments for Reorganization, Consolidation, Merger. If after the date hereof, the Company (or any other entity, the stock or other securities of which are at the time receivable on the exercise of the Warrants), consolidates with or merges into another entity or conveys all or substantially all of its assets to another entity, then, in each such case, Warrantholder, upon any permitted exercise of a Warrant (as provided in Section 7), at any time after the consummation of such reorganization, consolidation, merger or conveyance, shall be entitled to receive, inlieu of the stock or other securities and property receivable upon the exercise of the Warrant prior to such consummation, the stock or other securities or property to which such Warrantholder would have been entitled upon the consummation of such reorganization, consolidation, merger or conveyance if such Warrantholder had exercised the Warrant immediately prior thereto, all subject to further adjustment as provided in this Section 8. The successor or purchasing entity in any such reorganization, consolidation, merger or conveyance (if other than the Company) shall duly execute and deliver to Warrantholder a written acknowledgment of such entity’s obligations under the Warrants and this Agreement.

C. Adjustments Upon Issuance of Additional Stock.

If, at any time prior to the Warrant Expiration Date, the Company shall issue ''Additional Stock'' (as hereafter defined) for a consideration per share less than the Exercise Price, then and in that event, the Exercise Price shall be reduced concurrently with that issue to a price equal to the aggregate consideration paid per share in that issue. For purposes of this Section 8(C), ''Additional Stock'' shall mean all shares of Common Stock issued by the Company after the date on which the Warrants were first issued other than shares of Common Stock (or securities convertible into shares of Common Stock) issued or issuable at any time (i) to officers, directors, and employees of, and consultants to, the Company after the date on which the Warrants were first issued as designated and approved by the Board of Directors; (ii) in connection with equipment leasing or bank financing transactions approved by the Company's Board of Directors; (iii) shares of Common Stock issued upon the exercise of securities convertible into Common Stock which were granted prior to the date on which the Warrants were first issued; and (iv) securities of the Company issued to a Strategic Investor (hereafter defined). As used herein, “Strategic Investor” means that a majority of the Company's Board of Directors determines that such investor is a strategic investor and the Company does not issue to such investor more than ten percent (10%) of the Company's then outstanding securities.

- 3 -

For the purpose of making any adjustment in the Exercise Price as provided herein, the consideration received by the Company for any issue or sale of shares of Common Stock will be computed as follows:

(i) To the extent it consists of cash, as the amount of cash received by the Company before deduction of any offering expenses payable by the Company and any underwriting or similar commissions, compensation, or concessions paid or allowed by the Company in connection with the issue or sale;

(ii) To the extent it consists of property other than cash, at the fair market value of that property as determined in good faith by the Company's Board of Directors; and

(iii) If shares of Common Stock are issued or sold together with other stock or securities or other assets of the Company for a consideration which covers both, as the portion of the consideration so received that may be reasonably determined in good faith by the Board of Directors to be allocable to those shares of Common Stock.

If the Company (i) grants any rights or options to subscribe for, purchase, or otherwise acquire shares of Common Stock, or (ii) issues or sells any security convertible into shares of Common Stock, then, in each case, the price per share of Common Stock issuable on the exercise of the rights or options or the conversion of the securities will be determined by dividing the total amount, if any, received or receivable by the Company as consideration for the granting of the rights or options or the issue or sale of the convertible securities, plus the minimum aggregate amount of additional consideration payable to the Company on exercise or conversion of the securities, by the maximum number of shares of Common Stock issuable on the exercise of conversion. Such a grant, issue, or sale will be considered to be an issue or sale for cash of the maximum number of shares of Common Stock issuable on exercise or conversion at the price per share determined under this section, and the Exercise Price will be adjusted as provided above to reflect (on the basis of that determination) the issue or sale. No further adjustment of the Exercise Price will be made as a result of the actual issuance of shares of Common Stock on the exercise of any such rights or options or the conversion of any such convertible securities.

D.Notice of Certain Events.

Upon the occurrence of any event resulting in an adjustment in the number of Warrant Shares (or other stock or securities or property) receivable upon the exercise of the Warrants or the Exercise Price, the Company shall promptly thereafter (i) compute such adjustment in accordance with the terms of the Warrants, (ii) prepare a certificate setting forth such adjustment and showing in detail the facts upon which such adjustment is based, and (iii) mail copies of such certificate to Warrantholder.

Section 9. Reservation of Shares.

The Company shall at all times reserve and keep available, free from preemptive rights, out of the aggregate of its authorized but unissued Common Stock, or its authorized and issued Common Stock held in its treasury, the aggregate number of the Warrant Shares deliverable upon the exercise of all outstanding Warrants, for the purpose of enabling it to satisfy any obligation to issue the Warrant Shares upon the due and punctual exercise of the Warrants, through 5:00 p.m., Eastern time, on the Warrant Expiration Date.

- 4 -

Section 10. No Impairment.

The Company shall not, by amendment of its certificate of incorporation or bylaws, or through reorganization, consolidation, merger, dissolution, issuance or sale of securities, sale of assets or any other voluntary action, willfully avoid or seek to avoid the observance or performance of any of the terms of the Warrants or this Agreement, and shall at all times in good faith assist in the carrying out of all such terms and in the taking of all such actions as may be necessary or appropriate in order to protect the rights of Warrantholder under the Warrants and this Agreement against wrongful impairment. Without limiting the generality of the foregoing, the Company: (i) shall not set or increase the par value of any Warrant Shares above the amount payable therefor upon exercise, and (ii) shall take all actions that are necessary or appropriate in order that the Company may validly and legally issue fully paid and nonassessable Warrant Shares upon the exercise of the Warrants.

Section 11. Representations and Warranties of Warrantholder.

Warrantholder represents and warrants to the Company that, on the date hereof and on the date the Warrantholder exercises the Warrant pursuant to the terms of this Agreement:

A.Warrantholder understands that the Warrants and the Warrant Shares have not been registered under the Securities Act and acknowledges that the Warrants and the Warrant Shares must be held indefinitely unless they are subsequently registered under the Securities Act or an exemption from such registration becomes available.

B. Warrantholder is acquiring the Warrants for Warrantholder’s own account for investment and not with a view to, or for sale in connection with, any distribution thereof.

C. Warrantholder understands that the Warrants and the Warrant Shares are being offered and sold to him in reliance on an exemption from the registration requirements of United States federal and state securities laws under Regulation D promulgated under the Securities Act and that the Company is relying upon the truth and accuracy of the representations, warranties, agreements, acknowledgments and understandings of the Warrantholder set forth herein in order to determine the applicability of such exemptions and the suitability of the Warrantholder to acquire the Warrants and Warrant Shares.

D. All the representations made by the Warrantholder in the Promissory Note dated the date hereof between the Company and the Warrantholder (the “Note”) shall be true and correct as of the date the Warrantholder exercises the Warrant. Warrantholder further understands that if the information provided by the Warrantholder in the Note between the Company and the Warrantholder are not true and accurate before or at the time of the exercise of the Warrants, the Warrantholder shall inform the Company before or at the time of the exercise of the Warrants.

Re: Letter of Intent

Gentlemen:

This Letter of Intent (this “Agreement”) shall set forth our mutual agreement regarding a transaction (the “Transaction”) whereby Sentra Consulting Corp. (“Purchaser”) shall issue common stock in exchange for all the issued and outstanding membership interests of Karat Platinum LLC (the “Company”). This Agreement is intended solely as a basis for further discussion and is not intended to be and does not constitute a legally binding obligation except as provided below. No other legally binding obligations will be created, implied, or inferred until documentation in final form is executed and delivered by all parties. Without limiting the generality of the foregoing, it is the parties intent that, until that event, no agreement shall exist among them and there shall be no obligations whatsoever based on such things as parol evidence, extended negotiations, “handshakes,” oral understandings, or courses of conduct (including reliance and changes of position), except as provided below.

1.The Transaction. Purchaser hereby offers to purchase all of the issued and outstanding membership interests of the Company from the current owners thereof in consideration for the issuance of 30,000,000 shares of common stock (the “Consideration Shares”) of the Purchaser and 500,000 common stock purchase warrants, each of which will provide the Company the right to purchase one share of common stock of Purchaser for $0.01 until ten years after the date hereof (the “Consideration Warrants,” and together with the Consideration Shares, the “Consideration Securities”). The Consideration Securities shall be issued to the owners of the Company in proportion to their current equity ownership interest in the Company. If, after the date hereof but prior to the Closing (hereafter defined), Purchaser issues additional shares of common stock or other securities convertible into common stock to a third party without the written consent of Company (except for shares of common stock issued upon the exercise of securities convertible into common stock which were granted prior to the date hereof (which Purchaser represents only includes a warrant for 50,000 shares of common stock)), the number of Consideration Securities will be adjusted so that the number of Consideration Shares and shares of common stock issuable upon exercise of the Consideration Warrants will be equal to 90.7% of the outstanding shares of common stock of Purchaser. Upon consummation of the proposed transaction, the Company shall become a wholly-owned subsidiary of Purchaser.

2.Closing. The closingof the Transaction (the “Closing”) is subject to the following terms:

(i)   The loan by Purchaser to the Company of not less than $1,000,000;

(ii)   Purchaser performing its full due diligence over the Company and being fully satisfied in its absolute discretion with the due diligence;

(iii)   Company performing its full due diligence over the Purchaser and being fully satisfied in its absolute discretion with the due diligence;

(iv)   Delivery to Purchaser of evidence satisfactory to Purchaser that the agreement with Allgemeine Gold-und Silberscheideanstalt AG dated January 13, 2004_is valid, binding and enforceable against the parties thereto;

(v)   Consent from ABN Amro Bank NV, or Harrods Capital LLC, and the lenders to the Company to the Transaction and/or release of the collateral which is pledged to the foregoing persons or entities satisfactory to the Purchaser;

(vi)   Approval of the Transaction by the board of directors of Purchaser and the managers and members of the Company;

(vii)   Delivery of audited financial statements of the Company, in form and substance satisfactory to Purchaser and its independent public auditors; and

(viii)   Execution and delivery of documentation appropriate for the Transaction in form and substance mutually acceptable to both parties, including containing customary terms, representations, conditions, covenants and indemnities for a transaction of this nature.

Subject to the forgoing, it is the intent of the parties that definitive documentation with respect to the transactions contemplated in this Agreement shall be executed and delivered within 120 days from the date hereof (hereinafter referred to as the “Outside Closing Date”) and the parties shall use their best efforts to achieve same.

3. Due Diligence. Each of the Company and its representatives, on one hand, and the Purchaser and its representatives, on the other hand, shall enable the officers, accountants, counsel, bankers and other representatives of such other party access to its properties, books, records, personnel, business and other commercial relationships, and will fully cooperate in order that such other party may have full opportunity to make such investigation as it desires to make.

2

4. Exclusivity.In consideration of the above, the Company shall not, directly or indirectly, through any director, officer, member, manager, employee, agent, creditor, representative or otherwise (and each of said parties shall use reasonable efforts to insure such persons shall not directly or indirectly) (i) solicit, initiate or encourage the submission of inquiries, proposals or offers from any person or entity relating to (x) any business combination with respect to the Company or the business of the Company; or (y) the sale of any of the assets and/or securities of the Company (an "Alternative Transaction"), (ii) enter into or participate in any negotiations, or initiate any discussions or continue any discussions initiated by others, regarding any Alternative Transaction, or furnish to any other person or entity any information with respect to the assets or business of the Company or its business for the purposes of pursuing a possible Alternative Transaction with any other party, or (iii) otherwise participate in, assist, facilitate or encourage any effort or attempt by any other person or entity to do any of the foregoing. The Company shall promptly notify the Purchaser of any proposal or inquiry made to it or any of its directors, officers, members, managers, creditors, employees, agents, representatives, or otherwise with respect to any of the foregoing.

The foregoing exclusivity shall terminate upon the earlier of the Closing, or the Outside Closing Date, or the date Purchaser terminates this Agreement, provided, however, that if the Transaction has not been consummated prior to the Outside Closing Date as a result of the Purchaser not fulfilling its obligations provided for herein, including without limitation, the loan described in Section 2(i) above, the Company shall be released from its obligations hereunder and this Agreement shall be terminated and have no further force and effect, and provided, further that if the Transaction has not been consummated prior to the Outside Closing Date as a result of the Company not fulfilling its obligations provided for herein, including without limitation, those provided for in Sections 2(iv), (v) and (vii), the exclusivity shall continue until the earlier of the termination of this Agreement by the Purchaser or 60 days after the Outside Closing Date.

The restrictions herein provided shall not apply with respect to Confidential Information which (i) is or becomes a part of the public domain without breach of this Section 7 hereof or (ii) is disclosed pursuant to judicial action or government regulations, provided the receiving party notifies the disclosing party prior to such disclosure and cooperates with the disclosing party in the event the disclosing party elects to legally contest and avoid such disclosure.

3

(ii) Except as required by applicable law and in connection with the Transaction, neither party shall disclose nor permit its respective officers, representatives, agents or employees to discuss the existence or terms of this Agreement to any third party without the prior written consent of Purchaser.

8.Board of Directors. The consummation of the Transaction will result in a change of control of Purchaser. The parties agree that upon the Closing, each of the Company and Purchaser shall appoint two members to the Board of Directors of Purchaser and said members shall mutually appoint a fifth member to the Board.

9. Binding Effect; Termination. The parties agree to negotiate in good faith the terms and conditions of the definitive agreements with respect to the Transaction until this Agreement is terminated in accordance with the terms hereof. The parties will use their best efforts to effectuate the closing of the Transaction on or before the Outside Closing Date; provided, however, that this Agreement will terminate upon written notice by Purchaser to the Company at any time prior thereto. Except with respect to paragraphs 6 through 11, inclusive, the parties shall no longer have any rights or obligations with respect to this Agreement after the termination hereof.

10.Governing Law.This Agreement shall be governed by and construed in accordance with the laws of the State of New York applicable to agreements made and to be performed therein without giving effect to conflict of law principles.

11.Binding Effect. This Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns. No assignment of this Agreement or any right or obligation hereunder made be made by the parties and any such attempted assignment shall be void.
