3.2       Investment Intent: Blue Sky.  Purchaser is acquiring the Shares for investment for its own account, not as a nominee or agent, and not with a view to, or for resale in connection with, any distribution thereof.  It understands that the issuance of the Shares have not been, and will not be, registered under the Securities Act by reason of a specific exemption from the registration provisions of the Securities Act, the availability of which depends upon, among other things, the bona fide nature of the Purchaser’s investment intent and the accuracy of the Purchaser’s representations as expressed herein. 

3.4       Rule 144.  Purchaser acknowledges that the Shares must be held indefinitely unless subsequently registered under the Securities Act or unless an exemption from such registration is available.  It is aware of the provisions of Rule 144 promulgated under the Securities Act which permit limited public resale of shares purchased in a private placement subject to the satisfaction of certain conditions, including, among other things, the existence of a public market for the shares, the availability of certain current public information about the Company, the resale occurring not less than one year after a party has purchased and paid for the security to be sold, the sale being effected through a "broker's transaction" or in a transaction directly with a "market maker," and the number of shares being sold during any three‑month period not exceeding specified limitations.

3.5       Restrictions on Transfer; Restrictive Legends.  Purchaser understands that the transfer of the Shares is restricted by applicable state and federal securities laws and that the certificates representing the Shares will be imprinted with legends restricting transfer except in compliance therewith.

SECTION 4

Profits Interest

4.1.      Grant of Profits Interest. Purchaser does hereby grant to Seller a profits interest in the sales of the Shares payable under the following circumstances:

All proceeds (net of any brokerage commissions, sales fees and transfer taxes) from sale of any or all of the Shares, regardless of the per Share sales price, shall first be applied to payment of all principal and interest on the Promissory Note, until the Promissory Note is paid in full.

Next, all proceeds (net of any brokerage commissions, sales fees and transfer taxes) from any additional sales of any or all of the Shares, regardless of the per Share sales price, up to a cumulative total of $880,000 shall be retained by NHLT Equity Partners, L. P.

Upon satisfaction of the requirements of paragraphs 4.1.1 and 4.1.2 above, Seller shall be entitled to receive a "Profits Interest" equal to twenty percent (20%) of all proceeds (net of any brokerage commissions, sales fees and transfer taxes) from the sales, if any, of the remaining balance of the Shares. Purchaser shall remit to Seller the profits interest amount within five (5) business days of receipt of good (collected) funds from each sale.

4.2       Release of Security Agreement. Notwithstanding the Profits Interest granted above, Seller shall release the liens created in the Security Agreement upon the final payment of the amounts owing under the Promissory Note.

4.3       Nature of Profits Interest.

4.3.1                Speculative Nature.  Purchaser acknowledges and confirms that: (i) Purchaser and Seller have conferred specifically concerning the contingent and uncertain nature of the Profits Interest; (ii) Seller and Purchaser understand and agree that the Profits Interest payable as a result of this Agreement is highly speculative in nature; (iii) both the payments and amount, if any, of the Profits Interest are dependent upon a number of contingencies which are not within Purchaser's control, including, but not limited to, investor interest in the market for shares of NHLT, the corporation's financial performance, and the general state of the stock market and of the U. S. economy; and (iv) the grant of the Profits Interest is for a business purpose.

4.3.2                Statements, Books and Records.  Purchaser shall keep and maintain at all times full and accurate books and records to reflect each distribution, dividend, sale, disposition or other transaction respecting the Shares at the address set forth in Paragraph 5.2 hereof, which records shall be available for inspection by Seller and Seller's representatives and copying at the expense of Seller during reasonable business hours for the purpose of verifying the accuracy of the payments made on account of the Profits Interest.

4.3.3                No Deduction for Negative Profits Interest.  If, at any time it is calculated, the Profits Interest shall be a negative amount, Seller in no way shall be liable for such amount, and there shall be no deduction or offset for such negative amount at any time when the Profits Interest subsequently shall be calculated.

4.3.4                Seller's Right to Elect to Receive Less than Entire Profits Interest.  Seller shall have the right, at Seller's sole discretion, at any time to elect to receive less than the full amount of Profits Interest which would be payable by Purchaser to Seller in accordance with the foregoing provisions.  Seller may exercise such election by delivering to Purchaser a written notice so stating, which notice may state that Seller elects to receive any fraction of the Profits Interest that would otherwise be payable (as specified in such notice).  Any such election by Seller shall not impair Seller's right subsequently to receive any Profits Interest that otherwise would be or have been payable, nor impair or affect any right, power or remedy which Seller otherwise may have, nor shall any such election be construed as a waiver of any such rights, powers or remedies.

4.3.5                Disputes Concerning Profits Interest.  Seller may notify Purchaser within thirty (30) days after receipt of any Profits Interest that Seller disputes any computation or item contained in any portion of the statement submitted with such Profits Interest.  In the event Seller so notifies Purchaser, the parties shall meet and in good faith shall attempt to resolve such disputed items.  If the parties are unable to resolve such disputed items, the dispute shall be submitted to arbitration.  The arbitrator shall be a single person chosen by agreement of the parties.  If the parties are unable to agree on the appointment of an arbitrator within thirty (30) days after receipt of the notice from the Seller required in the first sentence of this Paragraph, either party may apply to a court of competent jurisdiction within Travis County, Texas, for the appointment of an arbitrator pursuant to the Texas Arbitration Act.  The determination of such dispute by said arbitrator shall be final.  The fees of such arbitrator shall be paid by Seller unless such review shall indicate that the computation resulted in an underpayment to Seller of Profits Interest in an amount exceeding three percent (3%) of the amount actually owing to Seller, in which case the Purchaser shall pay the arbitrator's fee.  Purchaser shall pay any additional amount due to Seller within ten (10) days after the resolution of such dispute, together with interest thereon from the date such payment was originally due at the maximum rate allowed by law or, of there is no maximum rate, then at the rate of eighteen percent (18%) per annum.  In the event that the arbitrator determines that the amount of Profits Interest due to Seller was overstated, the Seller shall refund to Purchaser any such amount paid to Seller within ten (10) days after the resolution of such dispute, together with interest thereon from the date of such payment was due at the maximum rate.

4.4       Maximum Permissible Interest Rate.  In the event that, notwithstanding Paragraphs 4.1 through 4.3 hereof, any sum payable hereunder as a Profits Interest is adjudicated as constituting interest, then in no contingency or event whatsoever, shall the amount payable hereunder or under any other agreement between Seller and Purchaser exceed the highest lawful rate permissible under the applicable usury law.  If, from any circumstance whatsoever, fulfillment of any provision of this Agreement or any other agreement between Seller an Purchaser, at the time performance of such provision shall be due, shall involve transcending the limit of validity prescribed by law which a court of competent jurisdiction may deem applicable hereto, then, ipso facto, the obligation to be fulfilled shall be reduced to the limit of such validity, and if from any circumstance, Seller shall receive as interest an amount which would exceed the highest lawful rate, such amount which would be excessive interest shall be refunded to Purchaser.  All sums paid, or agreed to be paid, to Purchaser for the use, forbearance or detention of the indebtedness of Purchaser to Seller shall be amortized, prorated, allocated and spread throughout the full term of this Agreement so that the actual rate of interest on account of such indebtedness is uniform throughout the term thereof.

4.5       Effect of Certain Changes.

4.5.1                If there is any change in the shares of NHLT Common Stock through the declaration of dividends on Common Stock paid in equity securities of NHLT, recapitalization, stock splits, reverse splits, or combinations or exchanges of such shares, or other similar transactions, the obligations of the Purchaser to make payments under Paragraph 4.1 of this Agreement shall apply to the proceeds of all sales of securities or property issuable or distributable in respect of, or exchangeable for, the Shares.

4.5.2                In the event of the dissolution or liquidation of NHLT, or in the event of a merger or consolidation of NHLT with another company, or other similar transactions, each of the Shares covered by this Agreement shall be replaced for the purposes herein by (and the obligation to make payments under Paragraph 4.1 of this Agreement shall be deemed to pertain to) the proceeds of sales of all securities or property issuable or distributable in respect of, or exchangeable for, the Shares upon such dissolution, liquidation, merger or consolidation.

4.5.3                Except as contemplated by this Paragraph 4.5, the Seller shall have no rights by reason of any subdivision or consolidation of shares of stock of any class or the payment of any dividend or any other increase or decrease in the number of shares of stock of any class or by reason of any dissolution, liquidation, merger, or consolidation.
