(c) In the event of rejection of this subscription, or in the event the sale of the Debenture(s) subscribed for by the undersigned is not consummated by the Company for any reason (in which event this Subscription Agreement shall be deemed to be rejected), this Subscription Agreement and any other agreement entered into between the undersigned and the Company relating to this subscription shall thereafter have no force or effect and the Company shall promptly return or cause to be returned to the undersigned the purchase price remitted to the Company by the undersigned, without interest thereon or deduction therefrom.

3.1 Investor Representations and Warranties.

The undersigned hereby acknowledges, represents and warrants to, and agrees with, the Company and its affiliates as follows:

(a) The undersigned is acquiring the Debenture(s) 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. Further, the undersigned does not have any contract, undertaking, agreement or arrangement with any person to sell, transfer or grant participations to such person or to any third person, with respect to the Debenture(s), or the Common Stock into which same may convert, for which the undersigned is subscribing.

(b) The undersigned has full power and authority to enter into this Agreement, the execution and delivery of this Agreement has been duly authorized, if applicable, and this Agreement constitutes a valid and legally binding obligation of the undersigned.

(c) The undersigned acknowledges his understanding that the offering and sale of the Debentures is intended to be exempt from registration under the Securities Act of 1933, as amended (the "Securities Act") by virtue of Section 4(2) of the Securities Act and the provisions of Regulation D promulgated thereunder ("Regulation D"). In furtherance thereof, the undersigned represents and warrants to and agrees with the Company and its affiliates as follows:

(i) The undersigned realizes that the basis for the exemption may not be present if, notwithstanding such representations, the undersigned has in mind merely acquiring the Debenture(s) for a fixed or determinable period in the future, or for a market rise, or for sale if the market does not rise. The undersigned does not have any such intention;

(ii) The undersigned has the financial ability to bear the economic risk of his investment, has adequate means for providing for his current needs and personal contingencies and has no need for liquidity with respect to his investment in the Company;

(iii) ___________________________________ (insert name of Purchaser Representative: if none, so state) has acted as the undersigned's Purchaser Representative for purposes of the private placement exemption under the Securities Act. If the undersigned has appointed a Purchaser Representative (which term is used herein with the same meaning as given in Rule 501(h) of Regulation D), the undersigned has been advised by his Purchaser Representative as to the merits and risks of an investment in the Company in general and the suitability of an investment in the Debenture(s) for the undersigned in particular; and

(iv) The undersigned (together with his Purchaser Representative(s), if any) has such knowledge and experience in financial and business matters as to be capable of evaluating the merits and risks of the prospective investment in the Debenture(s). If other than an individual, the undersigned also represents it has not been organized for the purpose of acquiring the Debenture(s).

(d) The undersigned is an "accredited investor," as that term is defined in Rule 501 of Regulation D, a copy of which is attached hereto as Exhibit B.

(e) The undersigned and his Purchaser Representative(s), if any:

(i) Have been furnished with copies of the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 1998 and all Quarterly Reports on Form 10-Q filed thereafter to date, including all exhibits thereto, and any documents which may have been made available upon request for a reasonable period of time prior to the date hereof (collectively, the "Documents"). The undersigned or his Purchaser Representative(s) have carefully read the Documents and have relied solely (except as indicated in subsections (ii) and (iii) below) on the information contained in the Documents (including all exhibits thereto);

(ii) Have been provided an opportunity for a reasonable period of time prior to the date hereof to obtain additional information concerning the offering of the Debentures, the Company and all other information to the extent the Company possesses such information or can acquire it without unreasonable effort or expense;

(iii) Have been given the opportunity for a reasonable period of time prior to the date hereof to ask questions of, and receive answers from, the Company or its representatives concerning the terms and conditions of the offering of the Debentures and other matters pertaining to this investment, and have been given the opportunity for a reasonable period of time prior to the date hereof to obtain such additional information necessary to verify the accuracy of the information contained in the Documents or that which was otherwise provided in order for him to evaluate the merits and risks of purchase of the Debenture(s) to the extent the Company possesses such information or can acquire it without unreasonable effort or expense;

(iv) Have not been furnished with any oral representation or oral information in connection with the offering of the Debentures which is not contained herein or in the Documents; and

(v) Have determined that the Debenture(s) are a suitable investment for the undersigned and that at this time the undersigned could bear a complete loss of such investment.

The undersigned has relied on the advice of, or has consulted with only those persons, if any, named as Purchaser Representative(s) herein. Each Purchaser Representative is capable of evaluating the merits and risks of an investment in the Debentures and each Purchaser Representative has disclosed to the undersigned in writing (a copy of which is annexed to this Agreement) the specific details of any and all past, present or future relationships, actual or contemplated, between himself and the Company or any affiliate or subsidiary thereof.

(g) The undersigned represents, warrants and agrees that he will not sell or otherwise transfer the Debenture(s), or the Common Stock into which the Debenture(s) may convert, without registration under the Securities Act or an exemption therefrom and fully understands and agrees that he must bear the economic risk of his purchase because, among other reasons, the Debenture(s), and the Common Stock into which the Debenture(s) may convert have not been registered under the Securities Act or under the securities laws of any state and, therefore, cannot be resold, pledged, assigned or otherwise disposed of unless they are subsequently registered under the Securities Act and under the applicable securities laws of such states or an exemption from such registration is available. In particular, the undersigned is aware that the Debenture(s) and Common Stock into which the Debenture(s) may convert are "restricted securities," as such term is defined in Rule 144 promulgated under the Securities Act ("Rule 144"), and they may not be sold pursuant to Rule 144 unless all of the conditions of Rule 144 are met. The undersigned also understands that, except as otherwise provided herein, the Company is under no obligation to register the Debenture(s), or the Common Stock into which same may convert, on his behalf or to assist him in complying with any exemption from registration under the Securities Act or applicable state securities laws. The undersigned further understands that sales or transfers of the Debenture(s), or the Common Stock into which same may convert, are further restricted by state securities laws and the provisions of this Agreement.

(h) No representations or warranties have been made to the undersigned by the Company, or any officer, employee, agent, affiliate or subsidiary of the Company, other than the representations of the Company contained herein, and in subscribing for the Debentures the undersigned is not relying upon any representations other than those contained herein.

(i) Any information which the undersigned has heretofore furnished to the Company with respect to his financial position and business experience is correct and complete as of the date of this Agreement and if there should be any material change in such information he will immediately furnish such revised or corrected information to the Company.

(j) The undersigned understands and agrees that the certificates for the Debenture(s), or the Common Stock into which same may convert, shall bear, substantially, the following legend until (i) such securities shall have been registered under the Securities Act and effectively been disposed of in accordance with a registration statement that has been declared effective; or (ii) in the opinion of counsel for the Company such securities be may sold without registration under the Securities Act as well as any applicable "Blue Sky" or state securities laws:

"THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "ACT"), AND ARE SUBJECT TO RESTRICTIONS ON TRANSFERABILITY AS SET FORTH IN THIS CERTIFICATE. THE SECURITIES REPRESENTED HEREBY MAY NOT BE SOLD, TRANSFERRED, OR OTHERWISE DISPOSED OF IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT UNDER THE ACT OR AN OPINION OF COUNSEL, REASONABLY ACCEPTABLE TO COUNSEL FOR THE COMPANY, TO THE EFFECT THAT THE PROPOSED SALE, TRANSFER, OR DISPOSITION MAY BE EFFECTUATED WITHOUT REGISTRATION UNDER THE ACT."

(k) The undersigned understands that an investment in the Debentures is a speculative investment which involves a high degree of risk and the potential loss of his entire investment.

(l) The undersigned's overall commitment to investments which are not readily marketable is not disproportionate to the undersigned's net worth, and an investment in the Debentures will not cause such overall commitment to become excessive.

(m) The foregoing representations, warranties and agreements shall survive the Closing.

EXHIBIT B

DEFINITION OF ACCREDITED INVESTORS

Each investor must represent in writing that he or she qualifies as an "accredited investor," as such term is defined in Rule 501(a) of Regulation D under the Securities Act, and must demonstrate the basis for such qualification. To be an accredited investor, an investor must fall within any of the following categories at the time of the sale of the Securities to that investor:

(1) A bank as defined in Section 3(a)(2) of the Securities Act, or a savings and loan association or other institution as defined in Section 3(a)(5)(A) of the Securities Act, whether acting in its individual or fiduciary capacity; a broker or dealer registered pursuant to Section 15 of the Securities Exchange Act of 1934, as amended; an insurance company as defined in Section 2(13) of the Securities Act; an investment company registered under the Investment Company Act of 1940 or a business development company as defined in Section 2(a)(48) of that act; a Small Business Investment Company dealer by the United States Small Business Administration under Section 301(c) or (d) of the Small Business Investment Act of 1958; a plan established and maintained by a state, its political subdivisions, or any agency or instrumentality of a state or its political subdivisions, for the benefit of its employees, if such plan has total assets in excess of $5,000,000; an employee benefit plan within the meaning of the Employee Retirement Income Security Act of 1974, if the investment decision is made by a plan fiduciary, as defined in Section 3(21) of that act, which is either a bank, savings and loan association, insurance company or registered investment advisor, or if the employee benefit plan has total assets in excess of $5,000,000, or, if a self-directed plan, with investment decisions made solely by persons that are accredited investors;

(2) A private business development company as defined in Section 2(a)(22) of the Investment Advisers Act of 1940;

(3) An organization described in Section 501(c)(3) of the Internal Revenue Code of 1986, as amended, a corporation, a Massachusetts or similar business trust, or a partnership, not formed for the specific purpose of acquiring the Debentures, with total assets in excess of $5,000,000;

(4) A director or executive officer of the Company;

(5) A natural person whose individual net worth, or joint net worth with that person's spouse, at the time of such person's purchase of the Debentures exceeds $1,000,000;

(6) A natural person who had an individual income in excess of $200,000 in each of the two most recent years or joint income with that person's spouse in excess of $300,000 in each of those years and has a reasonable expectation of reaching the same income level in the current year;

(7) A trust, with total assets in excess of $5,000,000, not formed for the specific purpose of acquiring the securities offered, whose purchase is directed by a sophisticated person as described in Rule 506(b)(2)(ii) of Regulation D; or

(8) An entity in which all of the equity owners are accredited investors (as defined above). As used in this Memorandum, the term "net worth" means the excess of total assets over total liabilities. In computing net worth for the purpose of (5) above, the principal residence of the investor must be valued at cost, including cost of improvements, or at recently appraised value by an institutional lender making a secured loan, net of encumbrances. In determining income, an investor should add to the investor's adjusted gross income, as reported in a federal income tax return, any amounts attributable to tax-exempt income received, losses claimed as a limited partner in any limited partnership, deductions claimed for depletion, contributions to an IRA or Keogh retirement plan, alimony payments and any amount by which income for long-term capital gains has been reduced in arriving at adjusted gross income.
