2.       General Understanding

         Purchaser understands that the Securities have not been registered
         under the Act, and, accordingly, that the Issuer must be satisfied
         that the offer and sale of the Securities to the Purchaser will
         satisfy the requirements of Section 4(2) under the Act.  Purchaser and
         Issuer intend that the representations, declarations, and warranties
         set out in this Agreement will be relied upon in determining
         Purchaser's suitability as a purchaser of the Securities.

3.       Purchaser Representations and Covenants

         Purchaser represents, warrants, and acknowledges to the Issuer as
         follows:

a)       The Securities are being acquired for the account of Purchaser and its
         affiliates for investment, with no present intention of distributing
         or selling any portion thereof, and will not be transferred by
         Purchaser in violation of the Act.  No one other than Purchaser has
         any interest in or any right to acquire the Securities.

b)       The Securities have not been registered under the Act or qualified
         under any state securities law in reliance on an exemption from
         registration and qualification for private offerings.  Purchaser is
         purchasing the Securities without being furnished any offering
         literature or prospectus other than the SEC Filings (as defined in
         Section 3(k) below).

C)       Purchaser is an "accredited investor" under Rule 501(a)(3) of
         Regulation D under the Act and will sign the Accredited Investor
         Declaration, substantially in the form of Schedule "C", attached
         hereto, contemporaneously with the execution of this Agreement.

d)       No representations or warranties have been made to Purchaser by the
         Issuer or any agent of the Issuer other





                                       2
   3
         than those set forth in this Agreement.

e)       Purchaser has investigated the acquisition of the Securities to the
         extent it deems necessary or desirable and the Issuer has provided it
         with any assistance it has requested in connection therewith.

f)       The address set forth below is the true and correct address of
         Purchaser's principal business office.

g)       Purchaser has full power and authority to make the representations
         referred to herein, to purchase the Securities, and to execute and
         deliver this Agreement.

h)       If Purchaser is not located in the United States, Purchaser has
         satisfied himself as to the full observance of the laws of the
         Purchaser's jurisdiction in connection with the offer and sale of the
         Securities or any use of this Agreement, including (i) the legal
         requirements of the Purchaser's jurisdiction for the purchase of
         Securities, (ii) any foreign exchange restrictions applicable to such
         purchase, and (iii) any governmental or other consents that may need
         to be obtained, and (iv) the income tax and other tax consequences, if
         any, which may be material to the purchase, holding, redemption,
         exchange, sale or transfer of the Securities.  Purchaser's purchase
         and payment for, and Purchaser's continued beneficial ownership of the
         Securities will not violate any applicable securities or other laws of
         Purchaser's jurisdiction.

i)       Purchaser is aware that this is a private offering and that no United
         States federal, state or other agency has made any finding or
         determination as to the fairness of the investment nor made any
         recommendation or endorsement of the Securities;

j)       Purchaser acknowledges and represents that Purchaser has had access to
         information concerning the Issuer and its subsidiaries, its
         management, its current and proposed business and other details of the
         investment believed by Purchaser to be sufficient to enable Purchaser
         to make an informed investment decision regarding Purchaser's
         acquisition of the Securities.  Purchaser has had an opportunity to
         ask questions of, and receive answers from, and obtain additional
         information from representatives of the Issuer concerning (i) the
         business and financial condition of the Issuer; (ii) the current and
         proposed business of the Issuer; and (iii) the terms of this Agreement
         and the purchase of the Securities, all to the extent such information
         is available or could be





                                       3
   4
         acquired without unreasonable effort or expense.

k)       Purchaser represents that Purchaser or its representative has received
         copies of the Form 10 Registration Statement under the Securities
         Exchange Act of 1934 filed by the Issuer on April 3, 1997 and will
         receive all amendments thereto (collectively "SEC Filings").

l)       Purchaser represents that all data or information requested by
         Purchaser from the Issuer or any of its officers or affiliates
         concerning the Issuer has been furnished to Purchaser.

m)       Purchaser represents and warrants to the Issuer that (i) Purchaser is
         able to bear the economic risk of an investment in the Securities;
         (ii) Purchaser has adequate means of providing for Purchaser's current
         needs and contingencies; (iii) Purchaser is purchasing the Securities
         for investment with the intention of holding the Securities for an
         indefinite period, and is able to afford to hold the Securities for an
         indefinite period; (iv) Purchaser has such knowledge and experience in
         financial and business matters that Purchaser is capable of evaluating
         the merits and risks of the investment in the Securities; (v)
         Purchaser can afford a complete loss of Purchaser's investment in the
         Securities; and (vi) Purchaser is willing to accept the foregoing
         investment risks.

n)       Purchaser represents and warrants to the Issuer that Purchaser's
         acquisition of the Securities is not a transaction (or any element of
         a series of transactions) that is part of a plan or scheme to evade
         the registration provisions of the Act.

o)       Purchaser understands that there is currently no trading market for
         the Securities and that none is expected to arise.  Purchaser further
         acknowledges that, although there currently exists a trading market
         for the Issuer's Common Stock, such market may not exist or be
         accessible in sufficient volume at such time as the Securities are
         converted into Common Stock.

Purchaser covenants to the Issuer that:

         excluding the SEC Filings, Purchaser has not distributed, and will not
         distribute any materials and has not divulged, and will not divulge,
         the contents thereof to anyone other than such legal or financial
         advisors as Purchaser has deemed necessary for purposes of evaluating
         an investment in the Securities and no one (except such





                                       4
   5
         advisors) has used such materials, and Purchaser has not made, and
         will not make, any copies thereof.

4.       Issuer Representations and Covenants.

         In order to induce Purchaser to enter into this Agreement, the Issuer
         represents and warrants to the Purchaser as follows:

         This private placement of Securities in the aggregate principal amount
         of up to $10,000,000.00 is being made on a "best efforts" basis
         pursuant to Section 4(2) of the Act. Such Securities may be issued in
         from one to five tranches of up to $2,000,000 per tranche, at one or
         more closings (each a "Closing") with no aggregate minimum investment
         amount, but all such Securities shall have identical rights, and
         privileges in all respects.

a)       The Securities, when issued and delivered pursuant hereto, and the
         Common Stock issuable upon conversion and/or exercise thereof, when
         issued and delivered upon such conversion and/or exercise thereof,
         will be duly and validly authorized and under federal or state law
         issued, fully paid and non-assessable and will not subject the
         Purchaser thereof to any liability solely by reason of being such
         Purchaser.

b)       The Issuer has full corporate power and authority to execute and
         deliver this Agreement and to perform its obligations hereunder and,
         when accepted by the Issuer, this Agreement will have been duly
         authorized by all necessary actions of the directors and (if
         necessary) the shareholders of Issuer, validly executed and delivered
         on behalf of the Issuer and be a legally binding obligation of the
         Issuer, enforceable in accordance with its terms.

c)       The execution and delivery of this Agreement and the sale of the
         Securities pursuant hereto and the issuance of the Common Stock
         issuable upon conversion and/or exercise thereof of such Securities,
         and the transactions contemplated by this Agreement do not and will
         not conflict with or result in a breach by the Issuer of any of the
         terms or provisions of, or constitute a default under, the Articles of
         Incorporation or By-Laws of the Issuer or any indenture, mortgage,
         deed of trust or other material agreement or instrument to which the
         Issuer is a party or by which it or any of its property or assets are
         bound or any existing applicable law, rule or regulation or any
         applicable decree, judgment or order of any court, federal or state
         regulatory body, administrative agency or other governmental body
         having jurisdiction over the Issuer or any of its properties or
         assets.





                                       5

d)       There are no facts or circumstances existing, and there has been no
         event, which has had or which reasonably could be expected to have in
         the future a material adverse effect with respect to the financial
         condition, business affairs or prospects of the Issuer other than as
         disclosed in the SEC Filings provided to Purchaser.

e)       Issuer is a corporation duly organized, validly existing and in good
         standing under the laws of the State of Nevada and is duly qualified
         and in good standing as a foreign corporation in all jurisdictions
         where the failure to so qualify would have a material adverse effect
         on the Issuer.  The Issuer has not registered its Common Stock
         pursuant to Section 12 of the Securities Exchange Act of 1934, as
         amended (the "Exchange Act") but filed a registration statement on
         Form 10 under the Exchange Act on April 3, 1997, and the Common Stock
         is traded on the Electronic Bulletin Board maintained by the National
         Association of Securities Dealers, Inc. under the symbol NVMH.

f)       The Purchaser shall, upon the purchase of the Securities and at each
         Closing, receive an opinion letter from the Issuer's counsel to the
         effect that (i) the Issuer is duly incorporated and validly existing;
         (ii) this Agreement, the issuance of the Securities, the issuance of
         Common Stock upon conversion and/or exercise thereof and the other
         transactions contemplated by this Agreement have been approved and
         duly authorized by all required corporate action; (iii) the
         Securities, upon delivery, shall be validly issued and outstanding,
         fully paid and nonassessable; and (iv) the Issuer has reserved from
         its authorized but unissued shares of Common Stock a sufficient number
         of shares to permit full conversion and/or exercise thereof at the
         then applicable conversion and/or exercise rate for all outstanding
         Securities.

(9)      Contemporaneously with the Closing of the first tranche the Issuer
         will pay all existing liens and encumbrances on the Issuer's Nevada
         mining properties and deliver a first trust deed on such properties in
         favor of Purchaser so that Purchaser shall have a senior security
         interest in such properties.

Covenants of the Issuer.

For so long as any Securities held by Purchaser remain outstanding, the Issuer
covenants and agrees with the Purchaser that:

a)       Issuer will undertake its best efforts to maintain the listing of its
         Common Stock on the Electronic Bulletin

   7
         Board, the NASDAQ SmallCap Stock Market or the American Stock
         Exchange;

b)       Except as expressly set forth in Section 7 below, and only until the
         Registration Statement (as hereinafter defined) has been declared
         effective, Issuer will not issue stop transfer instructions to its
         transfer agent in regard to the Securities or the Common Stock
         issuable upon conversion and/or exercise thereof of the Securities;

C)       The SEC Filings and any amendments thereto (i) do and will conform in
         all material respects to the rules and regulations of the Commission
         with respect thereto; (ii) do not and will not contain an untrue
         statement of a material fact or omit to state any material fact
         required to make the statements contained therein not misleading;

d)       Issuer will reserve from its authorized shares of Common Stock One
         Million Five Hundred Thousand (1,500,000) shares to permit conversion
         and/or exercise thereof in full of all outstanding Securities;

e)       Notwithstanding the foregoing, the conversion and/or exercise right of
         the Purchaser set forth herein shall be limited such that in no
         instance shall the maximum number of shares of Common Stock into which
         the Purchaser may convert these Securities exceed, at any one time, an
         amount equal to the remainder of (i) 4.99% of the then issued and
         outstanding shares of Common Stock of the Issuer following such
         conversion and/or exercise thereof, minus (ii) the number of shares of
         common Stock of the Issuer then held by the Purchaser;

f)       Neither the SEC Filings nor the Registration Statement (as hereinafter
         defined) or any amendments thereto, when declared effective will
         contain a misstatement of material fact or will omit a material fact
         necessary to make the statements contained therein not misleading; and

g)       The President and the Senior Vice President of the Issuer will confirm
         the warranties, representations and covenants contained in this
         Agreement at each Closing.

5.       Attorney's Fees: Due Diligence Fees.

         The Issuer agrees to pay all costs and expenses, including reasonable
         attorneys' fees, which may be incurred by the Purchaser in collecting
         any amount due or exercising the conversion and/or exercise rights
         under these Securities.  Further, the Issuer agrees to pay from escrow
         the Purchaser's legal fees and due diligence costs incurred in an
         amount of





                                       7
   8
         Twenty Five Thousand Dollars ($25,000.00), payable on the first
         tranche Closing and due diligence costs (estimated at $15,000) for
         representatives of Purchaser to travel to Issuer's facilities in
         Nevada, Brazil and Indonesia.

6.       Registration Rights; Liquidated Damages.

         The Purchaser will be entitled to registration rights in respect of
         the shares of Common Stock issuable upon conversion of the Debentures
         and exercise of the Warrants (the terms of which are set forth below)
         as follows: (1) The Issuer shall prepare and file, within 30 days of
         the initial Closing Date, and amendment to its registration statement
         under the Act on Form SB-2 (the "Registration Statement"), filed with
         the Securities and Exchange Commission (the "Commission") on December
         6, 1996, covering the resale of the shares of Common Stock issuable
         upon conversion of the Debentures and the shares of Common Stock
         issuable upon exercise of the Warrants.  The Issuer shall use its best
         efforts to cause the Registration Statement to be declared effective
         by the Commission no later than 120 days following the initial Closing
         Date and shall promptly deliver to Purchaser copies of all amendments
         to such Registration Statement and correspondence with the Commission
         with respect thereto.  The Issuer shall maintain the effectiveness of
         the Registration Statement until all of the Common Stock issuable or
         issued upon conversion or exercise of the Securities has been sold.
         The Issuer shall pay all expenses of registration (other than
         underwriting fees and discounts in respect of shares of Common Stock
         offered and sold under such registration statement by the Purchaser,
         if any). (2) If the Registration Statement is not declared effective
         by the Commission during the 120-day period mentioned above, the
         Company shall pay in cash (or common stock valued at Market Price, as
         hereinafter defined) to the Purchaser, as liquidated damages and not
         as a penalty, an amount equal to two percent (2%) per month
         (commencing 90 and ending 120 days after the initial Closing) of the
         outstanding principal amount of the Debentures, in the event that the
         Registration Statement is not declared effective by the Commission
         within 90 days of the initial Closing Date and three percent (3%) from
         120 days after the Closing Date until the Registration Statement is
         declared effective.

7.       Transfer Agent Instructions, Book-Entry System, Liquidated Damages.

         Each conversion of the Debentures and/or exercise of the Warrants will
         be effected through a "book-entry" mechanism.  Pursuant to this
         book-entry mechanism, (1) immediately following each Closing, the
         Escrow Agent will wire payment of the net offering proceeds to the
         Issuer and the Issuer will instruct the Issuer's transfer agent to
         register the Debentures in the name of the Purchaser on a Debenture





                                       8
   9
         Register to be maintained by such transfer agent for the benefit of
         the Issuer and the Purchaser; (2) the transfer agent will establish a
         set of book-entry procedures to record transfers and conversions of
         the Debentures; and (3) the Issuer will irrevocably instruct the
         transfer agent to issue shares of Common Stock, bearing such legend as
         may be required by law, to the Purchaser upon the valid exercise of
         the conversion privilege and the fulfillment of other requirements of
         the transfer agent, including but not limited to the effectiveness of
         the Registration Statement and the delivery of an opinion of the
         Company's counsel (which the Company shall promptly supply) as to the
         issuance of such shares of Common Stock.  If the Company willfully
         fails to deliver shares of Common Stock without restrictive legends or
         stop-transfer orders within four (4) New York Stock Exchange Trading
         Days of delivery of a notice of conversion following the effectiveness
         of the Registration Statement, or fails to deliver legended
         certificates if requested prior thereto, liquidated damages will
         accrue in an amount equal to $1,000.00 for each $100,000.00 principal
         amount of Debentures as to which conversion has been requested then
         outstanding for each day that such shares of Common Stock are not
         delivered up to 10 days, and $2,000.00 for each $100,000.00 principal
         amount of Debentures as to which conversion has been requested then
         outstanding for each day that such shares of Common Stock are not
         delivered in excess of 10 days.  Such amounts will accrue and be
         payable to the Purchaser by the Issuer upon demand notices of
         conversion shall be submitted by facsimile transmission and shall be
         deemed to have been received on the date transmitted.

8.       Indemnification.

         Each of the Issuer and the Purchaser agrees to indemnify and to hold
         the other harmless from and against any and all losses, damages,
         liabilities, costs and expenses which the other may sustain or incur
         in connection with the breach by the indemnifying party of any
         representation, warranty or covenant made in this agreement.  Each of
         the Issuer and the Purchaser agrees that the Escrow Agent shall be
         relieved of any liability arising out of acting as escrow agent and
         each also hereby agrees to indemnify the Escrow Agent against expenses
         including attorneys fees, judgements, fines and amounts paid in
         settlement incurred by the Escrow Agent as a result of any threatened,
         pending or completed action, suit or proceeding of every nature by
         reason of the fact that it served as escrow agent.

9.       Notices.

                 David L. Kagel
                 1801 Century Park East, #2500
                 Los Angeles, California 90067

                 Facsimile:       (310) 553 - 9693

         The Escrow Agent shall be entitled to a fee of $3,000 for each of the
         last four tranches which shall close.

10.      Closing Date.

         This agreement shall be effective from the date of execution by the
         Purchaser.  Each Closing shall be effected through delivery of funds
         and certificates to the Escrow Agent.  The Closing Date, which shall
         be so designated by a "Closing Certificate" from the Escrow Agent,
         shall be deemed to be that date upon which the Escrow Agent shall have
         the Securities available for delivery to the Purchaser and the
         Purchaser's funds in the Escrow Agent's account available for
         delivery to the Issuer.  The Debentures will be issuable in five
         tranches of $2,000,000 each.  The first tranche will close no later
         than April 15, 1997.  Subject to the provisions of Paragraph 11 the
         second tranche will close within five business days after the later of
         (a) the effective date of the SEC Filing, or (b) the conversion of the
         entire principal amount of Debentures purchased in the first tranche.
         Each of the next three tranches will close on the later of (a) ninety
         days following the Closing of the previous tranche, or (b) the
         conversion of the entire principal amount of Debentures purchased in
         the previous tranche.

11.      Right of First Refusal.

         Provided the Purchaser funds at least two tranches the Issuer will not
         sell any new equity securities (or securities convertible into equity
         securities) at a discount to the then-current market price per share
         of Common Stock, other than offerings in connection with mergers,
         acquisitions and certain benefit plans of the Issuer (a "discounted
         equity offering") for a period of ninety (90) Days from the funding of
         the last tranche.  At any time after the effective date of the
         Registration Statement and prior to the funding of all tranches
         contemplated hereunder Issuer may give written notice (a "Funding
         Notice") to Purchaser that funding of a tranche is





                                       10
   11
         requested.  Funding of any tranche after the first is at the sole
         discretion of the Purchaser.  If Purchaser shall elect not to fund
         such tranche by written notice to Issuer or by failing to effect a
         Closing within five days of receipt of a Funding Notice, and provided
         that such failure to is not the result of Issuer's inability or
         unwillingness to satisfy its obligations for such Closing, Issuer
         shall be free to sell any of its securities to any third party.  In
         the event of such sale the Purchaser of such securities shall not
         effect a public distribution of Common stock of Issuer until the
         earlier of (a) 90 days following the effective date of the SEC Filing,
         or (b) the conversion of 75 percent of the Common Stock issuable upon
         exercise of the Debentures.  Provided the Purchaser funds at least two
         tranches, for a period of one year from the Closing of the last
         tranche the Company will offer the Purchaser the opportunity to
         participate in all or any portion of any such financings on a right of
         first refusal basis.  The Purchaser will have five (5) days from the
         date of receipt of a notice of such offering to respond to any notice
         by the Issuer of any right of first refusal.

12.      Security.

         In order to secure its obligations under this Subscription Agreement
         and the Debentures Issuer will (a) grant Purchaser a first lien on the
         Issuer's gold mining claims and properties in the state of Nevada,
         which shall be released upon the conversion by Purchaser of 75% of the
         Debentures, and (b) arrange for Issuer to pledge 1,000,000 shares of
         common stock of Issuer in favor of Purchaser.

13.      Origination Fee.

         Issuer will pay from Escrow (and execute appropriate instructions with
         respect thereto) an origination fee of ten percent (10%) of the gross
         proceeds of the closing of the first two tranches and seven percent of
         the gross proceeds of each tranche thereafter to such persons and in
         such manner as Purchaser may advise.

14.      Conditions to the Issuer's Obligation to Sell.

         Issuer shall have the right to reject any given executed Agreement
         which is tendered to the Issuer hereunder, but only for the reason
         that the Issuer reasonably believes any representations and warranties
         of such Purchaser contained therein to be untrue, and in such event
         Issuer shall promptly provide Purchaser written notice of such
         rejection and the reason therefor and shall provide reasonable
         opportunity for a response to such stated reason.  Purchaser
         understands that Issuer's obligation to sell the Securities is
         conditioned upon:

         (i)     The receipt and acceptance by Issuer of this





                                       11
   12
                 Agreement for all of the Securities evidenced by execution of
                 this Agreement by the Issuer or Issuer's duly authorized
                 agent.  In the absence of a written acknowledgement of this
                 Agreement by the Issuer, the delivery of Securities to the
                 designated Escrow Agent and/or the transfer of funds to the
                 Issuer shall be deemed to be constructive acceptance of this
                 Agreement.

         (ii)    Delivery to the Escrow Agent by Purchaser of good funds as
                 payment in full of the Purchase Price of the securities
                 subscribed for and all fees and commissions hereunder.

15.      Conditions to Purchaser's Obligation to Purchase.

         Issuer understands that Purchaser's obligation to purchase the
         Securities is conditioned upon delivery of (i) the opinion of counsel
         specified in Section 4(i)(f) herein, (ii) the Securities as described
         herein, and (iii) such documents, certificates and other evidence of
         the Issuer's compliance with necessary corporate and statutory
         formalities as Purchaser shall reasonably require.  Further, the
         Purchaser anticipates being in a position to close and fund the
         initial tranche no later than April 15, 1997.  However, each Closing
         is conditioned upon (a) the execution and delivery of, and performance
         under, appropriate documentation (including but not limited to an
         executed agreement, form of debenture, warrants, and book entry
         transfer agreement), all in form and substance mutually acceptable to
         the parties and containing representations, warranties and agreements
         customary for transactions of this type; (b) the truth and accuracy of
         each of the representations and warranties contained herein, both when
         made and as of each Closing Date; (c) satisfactory completion of due
         diligence by Purchaser (applies to the initial Closing only); (d) the
         absence of any material adverse change in the business, condition
         (financial or otherwise), earnings or prospects of the Issuer; and
         (e) the availability of a valid exemption under the Act regarding the
         offering and sale of the Securities and shares of Common Stock
         issuable on the conversion or exercise thereof.

16.      Governing Law.

         This agreement shall be governed by and construed under the laws of
         the State of California without regard to its choice of law
         principles.

         This Agreement constitutes the entire agreement among the parties
         hereof with respect to the subject matter hereof and supersedes any
         and all prior or contemporaneous

                      NEVADA MANHATTAN MINING INCORPORATED
           8% SENIOR SECURED CONVERTIBLE DEBENTURE DUE MARCH 31, 2000

The securities represented hereby have not been registered under the Securities
Act of 1933, as amended (the "Act") and may not be sold, transferred or
hypothecated, except pursuant to registration under the Act or an exemption
from the registration requirements of the Act.

This Debenture is one of a duly authorized issue of Debentures of Nevada
Manhattan Mining Incorporated, a corporation duly organized and existing under
the laws of the state of Nevada (the "Issuer") designated as Eight Percent (8%)
Convertible Debentures Due March 31, 2000, in an aggregate principal amount not
exceeding Ten Million Dollars ($10,000,000.00).

FOR VALUE RECEIVED, the Issuer promises to pay to Silenus Limited, the
registered holder hereof and its successors and assigns (the "Holder"), the
principal sum of One Hundred Thousand Dollars ($100,000), on March 31, 2000
("Maturity Date"), and to pay interest on the principal sum outstanding at the
rate of 8% per annum.  Interest shall be due and payable quarterly on the last
day of June, September, December and March in each year.  Accrual of interest
shall commence on the first business day to occur after the date hereof and
shall continue until payment in full of the principal amount has been made or
duly provided for.  At the option of Issuer interest may be paid in common
stock of the Issuer ("Common Stock") at the average of the closing "bid" prices
for the common stock for the five trading days immediately prior to the date on
which such interest payment is due.  The interest so payable will be paid to
the person in whose name this Debenture (or one or more predecessor Debentures)
is registered on the records of the Issuer regarding registration and transfers
of the Debentures (the "Debenture Register"); provided, however, that the
Issuer's obligation to a transferee of this Debenture arises only if such
transfer, sale or other disposition is made in accordance with the terms and
conditions of the Subscription Agreement dated as of April 14, 1997 between the
Issuer and Holder (the "Subscription Agreement").  Except as set forth above,
the principal of, and interest on, this Debenture are payable in such coin or
currency of the United States of America as at the time of payment is legal
tender for payment of public and private debts, at the address last appearing
on the Debenture Register of the Issuer as designated in writing by the Holder
hereof from time to time.  The Issuer will pay the principal of and all accrued
and unpaid interest due upon





                                       16
   17
this Debenture on the Maturity Date, less any amounts required by law to be
deducted or withheld, to the Holder at the last address as set forth on the
Debenture Register.

This Debenture is subject to the following additional provisions:

1.       The Debentures are issuable in denominations of One Hundred Thousand
         Dollars ($100,000) and integral multiples thereof.  The Debentures are
         exchangeable for an equal aggregate principal amount of Debentures of
         different authorized denominations, as requested by the Holders
         surrendering the same.  No service charge will be made for
         registration, transfer or exchange.

2.       The Issuer shall be entitled to withhold from all payments of
         principal of, and interest on, this Debenture any amounts required to
         be withheld under the applicable provisions of the United States
         income tax or other applicable laws at the time of such payments.

3.       This Debenture has been issued subject to investment representations
         of the original Holder hereof and may be transferred or exchanged in
         compliance with the Act and applicable state securities laws.  Prior
         to the due presentment for transfer of this Debenture, the Issuer and
         any agent of the Issuer may treat the person in whose name this
         Debenture is duly registered on the Issuer's Debenture Register as the
         owner hereof for the purpose of receiving payment as herein provided
         and all other purposes, whether or not this Debenture be overdue, and
         neither the Issuer nor any such agent shall be affected by notice to
         the contrary.

4.       The Holder of this Debenture is entitled, at its option, at any time
         commencing forty-five days from the date hereof, to convert the
         principal amount of this Debenture into shares of Common Stock of the
         Issuer (the "Common Stock") at a conversion price for each share of
         Common Stock equal to Seventy-Five percent (75%) of the Market Price
         (as defined below) of the Common Stock for all conversions for which
         notice is received after the date hereof and a conversion price of
         Seventy-two and one-half percent (72 1/2%) of the Market Price
         thereafter.  For purposes of this Section 4, the "Market Price" shall
         be the lesser of (a) the closing bid price of the Common Stock on the
         day prior to the Closing of the first tranche; (b) the closing bid
         price of the Common Stock on the day prior to the Closing of any
         subsequent tranche; or (c) the average closing bid price of the Common
         Stock for the five (5) New York Stock Exchange Trading days
         immediately preceding each conversion date, in each case as reported
         by the National Association of Securities Dealers Automated Quoting
         System, or as reported by the American Stock Exchange of the Common
         Stock





                                       17
   18
         shall then be listed in trading upon such exchange.  Such conversion
         shall be effected by surrendering the Debentures to be converted (with
         a copy by facsimile or courier, to the Issuer) to the Issuer, with the
         form of conversion notice attached hereto as Exhibit 1, executed by
         the Holder of this Debenture or a specified portion (as provided)
         hereof, and accompanied, if required by the Issuer, by proper
         assignment hereof in blank.  No fractional shares or scrip
         representing fractions of shares will be issued on conversion or
         payment in lieu of interest, but the number of shares issuable shall
         be rounded to the nearest whole share, with the fraction paid in cash
         at the discretion of the Issuer.  For purposes of this Debenture, the
         "Conversion Date" on which notice of conversion is given shall be
         deemed to be the date on which the Holder has delivered by facsimile
         transmission a duly executed notice of conversion followed by delivery
         by mail or courier of this Debenture, with the conversion notice duly
         executed, to the Issuer, if such notice of conversion and this
         Debenture are received by mail or courier by the Issuer within three
         (3) business days.

5.       No provision of this Debenture shall alter or impair the obligation of
         the Issuer which is absolute and unconditional, to pay the principal
         of, and interest on, this Debenture at the place, time, and rate, and
         in the coin or currency, herein prescribed.

6.       The Issuer hereby expressly waives demand and presentment for payment,
         notice of nonpayment, protest, notice of protest, notice of dishonor,
         notice of acceleration or intent to accelerate, bringing of suit and
         diligence in taking any action to collect amounts called for hereunder
         and shall be directly and primarily liable for the payment of all
         sums owing and to be owing hereon, regardless of any without any
         notice, diligence, act or omission as or with respect to the
         collection of any amount called for hereunder.

7.       The Issuer agrees to pay all costs and expenses, including reasonable
         attorneys' fees which may be incurred by the Holder in collecting any
         amount due or exercising the conversion rights under this Debenture.

8.       If one or more of the following described "Events of Default" shall
         occur:

         (a)     The Issuer shall default in the payment of principal or
                 interest on this Debenture; or

         (b)     Any of the representations or warranties made by the Issuer
                 herein, in the Subscription Agreement, or in any certificate
                 or financial or other statements heretofore

   19
                 or hereafter furnished by or on behalf of the Issuer in
                 connection with the execution and delivery of this Debenture
                 or the Subscription Agreement shall be false or misleading in
                 any material respect at the time made; or

         (c)     The Issuer shall fail to perform or observe any other
                 covenant, term, provision, condition, agreement or obligation
                 of the Issuer under this Debenture or the Subscription
                 Agreement, including but not limited to conversion of this
                 Debenture as provided herein and therein, and such failure
                 shall continue uncured for a period of seven (7) days after
                 notice from the Holder of such failure; or

         (d)     The Issuer shall (1) become insolvent; (2) admit in writing
                 its inability to pay its debts generally as they mature; (3)
                 make an assignment for the benefit of creditors or commence

         competent jurisdiction to be excessive in scope or otherwise invalid
