                                    The Loan

         Section 3.01. Amount. On the terms and subject to the conditions of
this Agreement, the Lender agrees to lend to Borrower and Borrower agrees to
borrow from the Lender the Loan, in the amount of Three Million Dollars
($3,000,000) on the Closing Date.

         Section 3.02. Borrowing Procedure.

              (a)     Procedure for Term Loan Borrowing. Borrower shall give the
Lender irrevocable notice (which notice must be received by the Lender prior to
10:00 A.M., Tulsa, Oklahoma time, two Business Days prior to the Closing Date)
requesting that the Lender make the Loan on the Closing Date. Not later than
12:00 Noon, Tulsa, Oklahoma time, on the Closing Date, the Lender shall
transfer the amount of the Loan to the account of the Borrower specified in
such notice in immediately available funds.

         Section 3.03. Interest. Subject to Sections 3.04 and 8.11, Borrower
agrees to pay interest in arrears in respect of the outstanding principal
amount of the Loan from the Closing Date until the Maturity Date at a rate of
six and three tenths percent (6.3%) per annum (the "Loan Interest Rate").
Interest shall be computed on the last Business Day of each calendar month, and
if unpaid pursuant to the provisions of Section 3.06 hereof, added to the
outstanding principal amount of the Loan.

         Section 3.04. Additional Interest. Without limiting the remedies
available to the Lender under this Agreement or otherwise (and subject to the
provisions of Section 8.11), if Borrower fails to make any payment of principal
or interest (including interest payable under this Section) on or before its
due date as specified in this Agreement (whether at stated maturity or upon
prematuring by acceleration or otherwise) or, if not so specified, as notified
by the Lender to Borrower, Borrower shall pay, by way of liquidated damages, in
respect of the amount of such payment due and unpaid, interest at the rate of
twelve per cent (12%) per annum from the date any such payment became due until
the date of actual payment (as well after as before judgment). Such interest
shall be payable on demand.

         Section 3.05. Repayment. On or before the last Business Day of each
calendar month, commencing two months after the Closing Date, Borrower hereby
unconditionally promises to pay the Lender 40% of the Net Cash Flow realized by
NFE in the immediately preceding calendar month, as specified in an Officer's
Certificate delivered by Borrower to Lender in respect of such calendar month.
Such payments shall be applied, first, to pay any accrued but unpaid interest,
second, to pay any other amounts due to Lender under this Agreement, and third,
to reduce the outstanding principal amount of the Loan. In any case, Borrower
hereby unconditionally promises to pay the Lender any remaining outstanding
amount of the Loan on the Maturity Date, including any accrued and unpaid
interest thereon.

or Warrant Shares, the "Warrant Holders(s)").

         WHEREAS, Casuarina, Ltd.("Casuarina", a Bermuda corporation and wholly
owned subsidiary of Parker) and the Company have entered into a certain Credit
Agreement and Note (the "Credit Agreement") dated December ___, 1996, pursuant
to which Casuarina has agreed to loan $3,000,000 to the Company (the "Loan");

collectively, the "Warrants"), of the Company's Common Stock, par value $.001

         NOW, THEREFORE, in consideration of the premises and the mutual
agreements herein and in the Agreement set forth and for other good and
valuable consideration, the parties hereto agree as follows:

         1.      ISSUANCE OF WARRANTS: FORM OF WARRANT. The Company will issue

affiliate thereof designated by Parker, on the Closing Date referred to in the
Credit Agreement. The form of warrant certificate for the Original Warrants is

         The demand and the piggy-back registration rights set forth in Section

         2.      REPRESENTATIONS AND WARRANTIES OF THE COMPANY. The Company
hereby represents and warrants as follows:

                 (a)      EXISTENCE. The Company is a corporation, duly
         organized and validly existing under the laws of the State of Nevada,
         and is authorized to do business and is in good standing as a foreign
         corporation in every jurisdiction in which it owns or leases real
         property or in which the nature of its business requires it to be so
         qualified, except where the failure to so qualify, individually or in
         the aggregate, could not reasonably be expected to have a material
         adverse effect.

                 (b)      POWER AND AUTHORITY. The Company has all requisite
         corporate power and authority, and has taken all corporate action
         necessary, to execute, deliver and perform this Warrant Agreement, to
         grant, issue and deliver this Warrant and to authorize and reserve for
         issuance and, upon payment from time to time of the Exercise Price, to
         issue and deliver the shares of Common Stock or other securities
         issuable upon exercise of the Warrant. This Warrant Agreement has been
         duly executed and delivered by the Company.

                 (c)      RESERVATION, ISSUANCE AND DELIVERY OF COMMON STOCK.
         There have been reserved for issuance, and the Company shall at all
         times keep reserved, out of the authorized and unissued shares of
         Common Stock, a number of shares sufficient to provide for the
         exercise of the rights of purchase represented by the Warrant, and
         such shares, when issued upon receipt of payment therefor in
         accordance with the terms of the Warrant and of this Warrant
         Agreement, will be legally and validly issued, fully paid and
         nonassessable and will be free of any preemptive rights of
         shareholders or any restrictions not otherwise set forth in this
         Warrant Agreement.

                 (d)      EXECUTION AND DELIVERY. Neither the execution or
         delivery of this Warrant Agreement nor the consummation of the
         transactions herein contemplated does or will result in a breach or
         violation of any of the terms or provisions of, or constitute a
         default under, any indenture, mortgage, deed of trust, Credit
         Agreement or other agreement or instrument to which the Company is a
         party or by which the Company is bound or to which any of the property
         or assets of the Company is subject, nor will such action result in
         any violation of any provision of the Certificate of Incorporation or
         Bylaws of the Company or any statute or any order, rule or regulation
         or any court or governmental agency or body having jurisdiction over
         the Company or any of its properties; and no consent, approval,
         authorization, order, registration or qualification of or with any
         such court or governmental agency or body is required for the issuance
         and sale of the Warrant or the consummation by the Company of the
         transactions contemplated by this Warrant Agreement.

         (e)     VALID AND BINDING OBLIGATIONS. This Warrant Agreement and all
related documents, when duly executed and delivered, will be legal, valid and
binding obligations of the Company, enforceable in accordance with their
respective terms, subject to any applicable bankruptcy, insolvency or other
laws of general application affecting creditors' rights and judicial decisions
interpreting any of the foregoing.

         (f)     LIABILITIES, LITIGATION AND RESTRICTIONS. Except for the
litigation and liabilities disclosed in connection with the Credit Agreement,
the Company has no liabilities, direct or contingent, which may reasonably be
expected to result in a material adverse effect. Except as disclosed to Parker
in writing, no litigation or other action of any nature affecting the Company
is pending before any governmental authority or, to the knowledge of the
Company, threatened against or affecting the Company, which might reasonably be
expected to result in a material adverse effect.  To the knowledge of the
Company, no unusual or unduly burdensome restriction, restraint or hazard
exists by contract, law, governmental regulation or otherwise relative to the
business or material properties of the Company, other than such as relate
generally to persons engaged in the business activities similar to those
conducted by the Company.

         (g)     AUTHORIZATION AND CONSENTS. No authorization, consent,
approval, exemption, franchise, permit or license of, or filing with, any
governmental authority or other person is required to authorize, or is
otherwise required in connection with, the valid execution and delivery by the
Company of this Warrant Agreement and all related documents and the performance
by the Company of its obligations hereunder, except for requisite actions under
federal and state securities laws related to the registration of the Warrant
Shares as contemplated by this Warrant Agreement.

         (h)     COMPLIANCE WITH LAWS, RULES, REGULATIONS AND ORDERS. To the
knowledge of the Company, neither the business nor any of the activities of the
Company, as presently conducted, violates any requirement of law the result of
which violation could reasonably be expected to result in a material adverse
effect on the Company. The Company possesses all licenses, approvals,
registrations, permits and other authorizations necessary to enable it to carry
on its business in all material respects as now conducted; all such licenses,
approvals, registrations, permits and other authorizations are in full force and
effect; and the Company has no reason to believe that it will be unable to
obtain the renewal of any such licenses, approvals, registrations, permits and
other authorizations; however, this representation does not extend to such
necessary licenses, approvals, registrations, permits and authorizations of On-
Site Technology, L.L.C.

         (i)     NO MATERIAL MISSTATEMENTS. No information, statement,
certificate, document, exhibit or report prepared by or at the direction or
with the supervision of the Company and furnished to Parker in connection with
the negotiation and preparation of this Warrant Agreement or of the Credit
Agreement and all related documents contains any material misstatements of fact
or omits to state a material fact necessary to make the statements contained
therein not misleading as of the date made or deemed made.

         3.      CONDITIONS TO PURCHASE. Parker's obligations hereunder shall
be subject to satisfaction of the following conditions on the Closing Date
referred to in the Credit Agreement:

                 (a)      All corporate proceedings and other legal matters
         incident to the authorization, form and validity of this Warrant
         Agreement and the Warrants and all other legal matters relating to
         this Warrant Agreement, the Warrants and the transactions contemplated
         hereby shall be satisfactory in all respects to Ronald C. Potter,
         counsel for Parker, in his reasonable judgment, and the Company shall
         have furnished to such counsel all documents and information that he
         may reasonably request to enable him to pass judgment upon such
         matters.

                 (b)      There shall have been duly tendered to Parker or upon
         the order of Parker a certificate or certificates representing the
         Warrants.

                 (c)      Axelrod, Smith & Kirshbaum, counsel for the Company,
         shall have furnished to Parker their written opinion, dated the
         Closing Date, in form and substance satisfactory to Parker, covering
         the matters set forth in subparagraphs 2(a) through 2(g). Opinions by
         counsel for the Company covering the matters set forth in
         subparagraphs 2(f) and 2(g) shall be made to the best of such
         counsel's knowledge after reasonable inquiry.

                 (d)      As required by paragraph 18, Parker and counsel for
         Parker shall have received reimbursement for all reasonable fees and
         expenses for which invoices have been presented.

         4.      REGISTRATION. The Warrants shall be numbered and shall be
registered on the books of the Company (the "Warrant Register") as they are
issued. The Warrants shall be registered initially in such names and such
denominations as Parker has specified to the Company.

         5.      EXCHANGE OF WARRANT CERTIFICATES. Subject to any restriction
upon transfer set forth in this Warrant Agreement, each Warrant certificate may
be exchanged at the option of the Warrant Holder thereof for another
certificate or certificates of different denominations entitling the Warrant
Holder thereof to purchase upon surrender to the Company or its duly authorized
agent a like aggregate number of Warrant Shares as the certificate or
certificates surrendered then entitle such Warrant Holder to purchase. Any
Warrant Holder desiring to exchange a Warrant certificate or certificates shall
make such request in writing delivered to the Company, and shall surrender,
properly endorsed, the certificate or certificates to be so exchanged.
Thereupon, the Company shall execute and deliver to the person entitled thereto
a new Warrant certificate or certificates, as the case may be, as so requested.
Any Warrant issued upon exchange, transfer or partial exercise of the Warrants
shall be the valid obligation of the Company, evidencing the same generic
rights and entitled to the same generic benefits under this Warrant Agreement
as the Warrants surrendered for such exchange, transfer or exercise.

         6.      TRANSFER OF WARRANTS. Subject to the provisions of Section 14
hereof, the Warrants shall be transferrable only on the Warrant Register upon
delivery to the Company of the





                                       4
   22
Warrant certificate or certificates duly endorsed by the Warrant Holder or by
his duly authorized attorney-in-fact or legal representative, or accompanied by
proper evidence of succession, assignment or authority to transfer. In all
cases of transfer by an attorney-in-fact, the original power of attorney, duly
approved, or an official copy thereof, duly certified, shall be deposited with
the Company. In case of transfer by executors, administrators, guardians or
other legal representatives, duly authenticated evidence of their authority
shall be produced, and may be required to be deposited with the Company in its
discretion. Upon any registration of transfer, the Company shall deliver a new
Warrant or Warrants to the person entitled thereto.

         7.      TERM OF WARRANTS; EXERCISE OF WARRANTS.

                 (a)      The Warrants granted hereunder become exercisable
         upon the date of their issuance by the Company. Dates of issuance for
         the Warrants are specified in Section 1 hereof. Once issued, each
         Warrant entitles the Warrant Holder thereof to purchase one share of
         Common Stock at any time prior to 5:00 P.M., Tulsa time, on December
         31, 1998 (the "Expiration Date") at a purchase price of $2.50 per
         share, subject to adjustment in accordance with Section 12 hereof (the
         "Exercise Price").

                 (b)      The Exercise Price and the number of shares issuable
         upon exercise of Warrants are subject to adjustment upon the
         occurrence of certain events, pursuant to the provisions of Section 12
         of this Warrant Agreement. Subject to the provisions of this Warrant
         Agreement, each Warrant Holder shall have the right, which may be
         exercised as expressed in such Warrants, to purchase from the Company
         (and the Company shall issue and sell to such Warrant Holder) the
         number of fully paid and nonassessable shares of Common Stock
         specified in such Warrants, upon surrender to the Company, or its duly
         authorized agent, of such Warrants, with the purchase form on the
         reverse thereof duly filled in and signed, and upon payment to the
         Company of the Exercise Price, as adjusted in accordance with the
         provisions of Section 12 of this Warrant Agreement or upon a net
         exercise pursuant to this subsection of this Warrant Agreement, for
         the number of shares in respect of which such Warrants are then
         exercised. The Warrant Holder may (i) pay the Exercise Price in cash,
         by certified or official bank check payable to the order of the
         Company, or by the surrender to the Company securities of the Company
         having a Market Price equal to the Exercise Price or by the surrender
         to the Company indebtedness owed by the Company pursuant to the Credit
         Agreement (in which case the Company will accept such specified unpaid
         principal amount in full payment, as if such payment had been made in
         cash or (ii) make an exercise of Warrants for "Net Warrant Shares."
         The number of Net Warrant Shares will be determined as described by
         the following formula: Net Warrant Shares = [WS x (MP-EP)]/MP. "WS" is
         the number of Warrant Shares issuable upon exercise of the Warrants or
         portion of Warrants in question. "MP" is the Market Price of the
         Common Stock on the last trading day preceding the date of the request
         to exercise the Warrants. "Market Price" shall mean the then current
         market price per share of Common Stock, as determined in paragraph
         12.1(e). "EP" shall mean the Exercise Price.





                                       5
   23
         Upon such surrender of Warrants, and payment of the Exercise Price,
with cash or securities, or upon a net exercise as aforesaid, the Company at
its expense shall issue and cause to be delivered with all reasonable dispatch
to or upon the written order of the Warrant Holder and in such name or names as
the Warrant Holder may designate, a certificate or certificates for the number
of full shares of Common Stock so purchased upon the exercise of such Warrants,
together with cash, as provided in Section 12 of this Warrant Agreement, in
respect of any fraction of a share of such stock otherwise issuable upon such
surrender. Such certificate or certificates shall be deemed to have been issued
and any person so designated to be named therein shall be deemed to have become
a holder of record of such shares as of the date of the surrender of such
Warrants and payment of the Exercise Price or receipt of shares by net exercise
as aforesaid. The rights of purchase represented by the Warrants shall be
exercisable, at the election of the Warrant Holders thereof, either in full or
from time to time in part and, in the event that any Warrant is exercised in
respect of less than all of the shares purchasable on such exercise at any time
prior to the Expiration Date, a new certificate evidencing the remaining
Warrant or Warrants will be issued.

         8.      COMPLIANCE WITH GOVERNMENT REGULATIONS. The Company covenants
that if any share of Common Stock required to be reserved for purposes of
exercise or conversion of Warrants require, under any Federal or state law or
applicable governing rule or regulation of any national securities exchange,
registration with or approval of any governmental authority, or listing on any
such national securities exchange, before such shares may be issued upon
exercise, the Company will use its best efforts to cause such shares to be duly
registered, approved or listed on the relevant national securities exchange, as
the case may be.

         9.      PAYMENT OF TAXES. The Company will pay all documentary stamp
taxes, if any, attributable to the initial issuance of Warrant Shares upon the
exercise of Warrants and any securities issued pursuant to Section 12 hereof;
provided, however, that the Company shall not be required to pay any tax or
taxes which may be payable in respect of any transfer involved in the issue or
delivery of any Warrants or certificates for Warrant Shares and any securities
issued pursuant to Section 12 hereof in a name other than that of the Warrant
Holder of such Warrants.

         10.     MUTILATED OR MISSING WARRANTS. Upon receipt by the Company of
an affidavit signed by an officer of Parker evidencing the mutilation, loss,
theft or destruction of any of the Warrants, the Company shall issue and
deliver in exchange and substitution for and upon cancellation of the mutilated
Warrant, or in lieu of and in substitution for the Warrant lost, stolen or
destroyed, a new Warrant of like tenor and representing an equivalent right or
interest.

         11.     RESERVATION OF WARRANT SHARES; PURCHASE AND CANCELLATION OF
WARRANTS. The Company shall at all times reserve, out of the authorized and
unissued shares of Common Stock, a number of shares sufficient to provide for
the exercise of the rights of purchase represented by the Warrants, and the
transfer agent for the Common Stock ("Transfer Agent") and every subsequent
transfer agent for any shares of the Company's capital stock issuable upon the
exercise of any of the rights of purchase aforesaid are hereby irrevocably
authorized and directed at all times until the Expiration Date to reserve such
number of authorized and unissued shares as shall be requisite for such
purpose. The Company will keep a copy of this Warrant Agreement on file





                                       6
   24
with the Transfer Agent and with every subsequent transfer agent for any shares
of the Company's capital stock issuable upon the exercise of the rights of
purchase represented by the Warrants. The Company will supply the Transfer
Agent and any such subsequent transfer agent with duly executed stock
certificates for such purpose and will itself provide or otherwise make
available any cash which may be issuable as provided by Section 13 of this
Warrant Agreement. The Company will furnish to the Transfer Agent and any such
subsequent transfer agent a copy of all notices of adjustments, and
certificates related thereto, transmitted to each Warrant Holder pursuant to
Section 12.3 hereof. All warrants surrendered in the exercise of the rights
thereby evidenced shall be cancelled, and such cancelled Warrants shall
constitute sufficient evidence of the number of shares of stock which have been
issued upon the exercise of such Warrants (subject to adjustment as herein
provided). No shares of stock shall be subject to reservation in respect of the
Warrants subsequent to the Expiration Date except to the extent necessary to
comply with the terms of this Warrant Agreement.

         12.     ADJUSTMENT OF EXERCISE PRICE AND NUMBER OF WARRANT SHARES. The
number and kind of securities purchasable upon the exercise of each Warrant and
the Exercise Price shall be subject to adjustment from time to time upon the
occurrence of certain events, as hereafter defined.

                 12.1.    MECHANICAL ADJUSTMENTS. The number of Warrant Shares
         purchasable upon the exercise of each Warrant and the Warrant Price
         shall be subject to adjustment as follows:

                          (a)     In case the Company shall (i) pay a dividend
                 in shares of Common Stock or make a distribution in shares of
                 Common Stock, (ii) subdivide its outstanding shares of Common
                 Stock into a larger number of shares of Common Stock, (iii)
                 combine its outstanding shares of Common Stock into a smaller
                 number of shares of Common Stock or (iv) issue by
                 reclassification of its shares of Common Stock other
                 securities of the Company (including any such reclassification
                 in connection with a consolidation or merger in which the
                 company is the surviving corporation), the number of Warrant
                 Shares purchasable upon exercise of each Warrant immediately
                 prior thereto shall be adjusted so that the Warrant Holder
                 shall be entitled to receive the kind and number of Warrant
                 Shares or other securities of the Company which he would have
                 owned or have been entitled to receive after the happening of
                 any of the events described above, had such Warrant been
                 exercised immediately prior to the happening of such event or
                 any record date with respect thereto regardless of whether the
                 Warrants are exercisable at the time of the happening of such
                 event or at the time of any record date with respect thereto.
                 An adjustment made pursuant to this paragraph (a) shall become
                 effective immediately after the effective date of such event
                 retroactive to the record date, if any, for such event.

                          (b)     In case the Company shall issue rights,
                 options or warrants to holders of its outstanding Common Stock
                 (other than rights, options or warrants issued to an officer,
                 director or employee of the Company as compensation,





                                       7
   25
                 regardless of whether such officer, director or employee is a
                 holder of the Company's Common Stock immediately prior to such
                 issue), without any charge to such holders, entitling them to
                 subscribe for or purchase shares of Common Stock at a price
                 per share which is lower, at the record date mentioned below,
                 than the then current market price per share of Common Stock
                 (as determined in accordance with paragraph (e) below), then
                 in each such case the number of Warrant Shares thereafter
                 purchasable upon the exercise of each Warrant shall be
                 determined by multiplying the number of Warrant Shares
                 theretofore purchasable upon exercise of each Warrant by a
                 fraction, of which the numerator shall be the number of shares
                 of Common Stock outstanding on the date of issuance of such
                 rights, options or warrants plus the number of additional
                 shares of Common Stock offered for subscription or purchase,
                 and of which the denominator shall be the number of shares of
                 Common Stock outstanding on the date of issuance of such
                 rights, options or warrants plus the number of shares which
                 the aggregate offering price of the total number of shares of
                 common stock so offered would purchase at the then current
                 market price per share of Common Stock. Such adjustment shall
                 be made whenever such rights, options or warrants are issued,
                 and shall become effective immediately after the record date
                 for the determination of stockholders entitled to receive such
                 rights, options or warrants.

                          (c)     In case the Company shall distribute to
                 holders of its shares of Common Stock evidences of its
                 indebtedness or assets (including cash dividends or other cash
                 distributions) or rights, options or warrants, or convertible
                 or exchangeable securities containing the right to subscribe
                 for or purchase shares of Common Stock (excluding those
                 referred to in paragraph (b) above), then in each case the
                 number of Warrant Shares thereafter purchasable upon the
                 exercise of each Warrant shall be determined by multiplying
                 the number of Warrant Shares theretofore purchasable upon the
                 exercise of each Warrant by a fraction, of which the numerator
                 shall be the then current market price per share of Common
                 Stock (as determined in accordance with paragraph (e) below)
                 on the date of such distribution, and of which the denominator
                 shall be the then current market price per share of Common
                 Stock, less the then fair value (as determined in good faith
                 by the Board of Directors of the Company, whose determination
                 shall be conclusive, absent manifest error) of the portion of
                 the assets or evidences of indebtedness so distributed or of
                 such subscription rights, options or warrants, or of such
                 convertible or exchangeable securities applicable to one share
                 of Common Stock. Such adjustment shall be made whenever any
                 such distribution is made, and shall become effective on the
                 date of distribution retroactive to the record date for the
                 determination of stockholders entitled to receive such
                 distribution.

                          In the event of distribution, by the Company to
                 holders of its shares of Common Stock, of stock of a
                 subsidiary or securities convertible into or exercisable for
                 such stock, then in lieu of an adjustment in the number of
                 Warrant Shares purchasable upon the exercise of each Warrant,
                 the Warrant Holder, upon





                                       8
   26
                 the exercise thereof at any time after such distribution,
                 shall be entitled to receive from the Company, such subsidiary
                 or both, as the Company shall determine, the stock or other
                 securities to which such Warrant Holder would have been
                 entitled if such Warrant Holder had exercised such Warrant
                 immediately prior thereto regardless of whether the Warrants
                 are exercisable at such time, all subject to further
                 adjustment as provided in this subsection 12.1; provided,
                 however, that no adjustment in respect of dividends or
                 interest on such stock or other securities shall be made
                 during the term of a Warrant or upon the exercise of a
                 Warrant.

                          (d)     In case the Company shall sell and issue
                 shares of Common Stock (other than (i) the shares of Common
                 Stock being offered for sale pursuant to the filing on Form
                 SB-2 made by the Company with the Securities and Exchange
                 Commission dated October 29, 1996; and (ii) the shares of
                 Common Stock offered by the Company in a private placement
                 memorandum dated September 18, 1996, provided that no more
                 than 2,000,000 shares of Common Stock are offered or sold in
                 such private placement) or rights, options, warrants or
                 convertible securities containing the right to subscribe for
                 or purchase shares of Common Stock (excluding shares, rights,
                 options, warrants or convertible securities issued in any of
                 the transactions described in paragraphs (a), (b) or (c)
                 above) at a price per share of Common Stock (determined, in
                 the case of such rights, options, warrants or convertible
                 securities, by dividing (w) the total of the amount received
                 or receivable by the Company (determined as provided below) in
                 consideration of the sale and issuance of such rights,
                 options, warrants or convertible securities, by (x) the total
                 number of shares of Common Stock covered by such rights,
                 options, warrants or convertible securities) lower than 75% of
                 the then current market price per share of Common Stock (as
                 determined in accordance with paragraph (e) below) in effect
                 immediately prior to such sale and issuance, then the number
                 of Warrant Shares thereafter purchasable upon the exercise of
                 the Warrants shall be determined by multiplying the number of
                 Warrant Shares theretofore purchasable upon exercise by a
                 fraction, of which the numerator shall be the number of shares
                 of Common Stock outstanding on the date of issuance of such
                 shares, rights, options, warrants or convertible securities
                 plus the number of additional shares of Common Stock sold or
                 subject to issuance pursuant to such rights, options, warrants
                 or convertible securities, and of which the denominator shall
                 be the number of shares of Common Stock outstanding on the
                 date of issuance of such shares, rights, options, warrants or
                 convertible securities plus the number of shares of Common
                 Stock which the aggregate consideration received or receivable
                 (determined as provided below) for such sale or issuance would
                 purchase at 75% of the then current market price. Such
                 adjustment shall be made successively whenever such an
                 issuance is made. For the purposes of such adjustments, the
                 consideration received or receivable by the Company for
                 rights, options, warrants or convertible securities shall be
                 deemed to be the consideration received by the Company for
                 such rights, options, warrants or convertible securities, plus
                 the consideration or premiums stated in such rights, options,
                 warrants or convertible





                                       9

                 securities to be paid for the shares of Common Stock covered
                 thereby. In case the Company shall sell and issue shares of
                 Common Stock, or rights, options, warrants or convertible
                 securities containing the right to subscribe for or purchase
                 shares of Common Stock, for a consideration consisting, in
                 whole or in part, of property other than cash or its
                 equivalent, then in determining the "price per share of Common
                 Stock" and the "consideration received or receivable by the
                 Company" for purposes of the first sentence of this paragraph
                 (d), the Board of Directors shall determine, in its
                 discretion, the fair value of said property, and such
                 determination, if made in good faith, shall be binding upon
                 all Holders.

                          (e)     For the purpose of any computation under
                 paragraphs (b), (c) and (d) of this Section, the current
                 market price per share of Common Stock at any date shall be
                 the average of the daily closing prices of the Company's
                 Common Stock, as reported on the National Association of
                 Securities Dealers OTC Bulletin Board, for 30 consecutive
                 trading days commencing 45 trading days before the date of
                 such computation. The closing price for each day shall be the
                 last such reported sales price regular way or, in case no such
                 reported sale takes place on such day, the average of the
                 closing bid and asked prices regular way for such day, in each
                 case on the principal national securities exchange on which
                 the shares of Common Stock are listed or admitted to trading
                 or, if not listed or admitted to trading, the average of the
                 closing bid and asked prices of the Common Stock in the
                 over-the-counter market as reported by NASDAQ or any
                 comparable system. In the absence of one or more such
                 quotations, the Board of Directors of the Company shall
                 determine the current market price, in good faith, on the
                 basis of such quotations as it considers appropriate.

                          (f)     In any case in which this Section 12.1 shall
                 require that any adjustment in the number of Warrant Shares be
                 made effective as of immediately after a record date for a
                 specified event, the Company may elect to defer until the
                 occurrence of the event the issuing to the holder of any
                 Warrant exercised after that record date the shares of Common
                 Stock and other securities of the Company, if any, issuable
                 upon the exercise of any Warrant over and above the shares of
                 Common Stock and other securities of the Company, if any,
                 issuable upon the exercise of any Warrant prior to such
                 adjustment; provided, however, that the Company shall deliver
                 to such Warrant Holder a due bill or other appropriate
                 instrument evidencing the holder's right to receive such
                 additional shares or securities upon the occurrence of the
                 event requiring such adjustment.

                          (g)     No adjustment in the number of Warrant Shares
                 purchasable hereunder shall be required unless such adjustment
                 would require an increase or decrease of at least one percent
                 (1%) in the number of Warrant Shares purchasable upon the
                 exercise of each Warrant; provided, however, that any
                 adjustments which by reason of this paragraph (g) are not
                 required to be made shall be carried forward





                                       10
   28
                 and taken into account in any subsequent adjustment. All
                 calculations shall be made to the nearest one-thousandth of a
                 share.

                          (h)     Whenever the number of Warrant Shares
                 purchasable upon the exercise of each Warrant is adjusted, as
                 herein provided, the Warrant Price payable upon the exercise
                 of each Warrant shall be adjusted by multiplying such Warrant
                 Price immediately prior to such adjustment by a fraction, of
                 which the numerator shall be the number of Warrant Shares
                 purchasable upon the exercise of such Warrant immediately
                 prior to such adjustment, and of which the denominator shall
                 be the number of Warrant Shares purchasable immediately
                 thereafter.

                          (i)     No adjustment in the number of Warrant Shares
                 purchasable upon the exercise of each Warrant need be made
                 under paragraphs (b), (c) and (d) if the Company issues or
                 distributes to each Warrant Holder the rights, options,
                 warrants, or convertible or exchangeable securities, or
                 evidences of indebtedness or assets referred to in those
                 paragraphs which each Warrant Holder would have been entitled
                 to receive had the Warrants been exercised prior to the
                 happening of such event or the record date with respect
                 thereto, regardless of whether the Warrants are exercisable at
                 the time of the happening of such event or at the time of any
                 record date with respect thereto. No adjustment need be made
                 for a change in the par value of the Warrant Shares.

                          (j)     For the purpose of this Section 12.1, the
                 terms "shares of Common Stock" shall mean (i) the class of
                 stock designated as the Common Stock of the Company at the
                 date of this Agreement, or (ii) any other class of stock
                 resulting from successive changes or reclassifications of such
                 shares consisting solely of changes in par value, or from par
                 value to no par value, or from no par value to par value. In
                 the event that at any time, as a result of an adjustment made
                 pursuant to paragraph (a) above, the Warrant Holders shall
                 become entitled to purchase any securities of the Company
                 other than shares of Common Stock, thereafter the number of
                 such other securities so purchasable upon exercise of each
                 Warrant and the Exercise Price of such securities shall be
                 subject to adjustment from time to time in a manner and on
                 terms as nearly equivalent as practicable to the provisions
                 with respect to the Warrant Shares contained in paragraphs (a)
                 through (i), inclusive, above, and the provisions of Section 7
                 and Section 12.2 through 12.5, inclusive, with respect to the
                 Warrant Shares, shall apply on like terms to any such other
                 securities.

                          (k)     Upon the expiration of any rights, options,
                 warrants or conversion or exchange privileges, if any thereof
                 shall not have been exercised, the Warrant Price and the
                 number of shares of Common Stock purchasable upon the exercise
                 of each warrant shall, upon such expiration, be readjusted and
                 shall thereafter be such as it would have been had it been
                 originally adjusted (or had the original adjustment not been
                 required, as the case may be) as if (A) the only shares of
                 Common Stock





                                       11
   29
                 so issued were the shares of Common Stock, if any, actually
                 issued or sold upon the exercise of such rights, options,
                 warrants or conversion or exchange rights and (B) such shares
                 of Common Stock, if any, were issued or sold for the
                 consideration actually received by the Company upon such
                 exercise plus the aggregate consideration, if any, actually
                 received by the Company for the issuance, sale or grant of all
                 such rights, options, warrants or conversion or exchange
                 rights whether or not exercised; provided, however, that no
                 such readjustment shall have the effect of increasing the
                 Warrant Price or decreasing the number of Warrant Shares by an
                 amount in excess of the amount of the adjustment initially
                 made with respect to the issuance, sale or grant of such
                 rights, options, warrants or conversion or exchange rights.

         12.2.   VOLUNTARY ADJUSTMENT BY THE COMPANY. The Company may, at its
option, at any time during the term of the Warrants, reduce the then current
Exercise Price to any amount determined appropriate by the Board of Directors
of the Company.

         12.3.   NOTICE OF ADJUSTMENT. When the number of Warrant Shares
purchasable upon the exercise of each Warrant or the Exercise Price of such
Warrant Shares is adjusted, as herein provided, the Company shall promptly mail
by first class, postage prepaid, to each Warrant Holder notice of such
adjustment or adjustments and a certificate of a firm of independent public
accountants selected by the Board of Directors of the Company (who may be the
regular accountants employed by the Company) setting forth the number of
Warrant Shares purchasable upon the exercise of each Warrant and the Exercise
Price of such Warrant Shares after such adjustment and setting forth a brief
statement of the facts requiring such adjustment and setting forth the
computation by which such adjustment was made. Such certificate, absent
manifest error, shall be conclusive evidence of the correctness of such
adjustment.

         12.4.   PRESERVATION OF PURCHASE RIGHTS UPON MERGER, CONSOLIDATION,
ETC. In case of any consolidation of the Company with or merger of the Company
into another person or in case of any sale, transfer or lease to another person
of all of or substantially all the assets of the Company, the Company or such
successor or purchaser, as the case may be, shall execute with each Warrant
Holder an agreement that each Warrant Holder shall have the right thereafter
upon payment of the Exercise Price in effect immediately prior to such action
to purchase upon exercise of each Warrant the kind and amount of shares and
other securities and property which the Warrant Holder would have owned or have
been entitled to receive after the happening of such consolidation, merger,
sale, transfer or lease had such Warrant been exercised immediately prior to
such action regardless of whether the Warrants are exercisable at the time of
such action. Such agreement shall provide for adjustments, which shall be as
nearly equivalent as may be practicable to the adjustments provided for in this
Section 12. The provisions of this Section 12.4 shall similarly apply to
successive consolidations, mergers, sales, transfers or leases.

         12.5.   STATEMENT ON WARRANTS. Even though Warrants heretofore or
hereafter issued may continue to express the same price and number and kind of
shares as are stated in the Warrants initially issuable pursuant to this
Warrant Agreement, the parties understand and agree that such





                                       12
   30
Warrants will represent rights consistent with any adjustments in the Exercise
Price or the number or kind of shares purchasable upon the exercise of the
Warrants.

         13.     FRACTIONAL INTERESTS. The Company shall not be required to
issue fractional Warrant Shares on the exercise of Warrants. If more than one
Warrant shall be presented for exercise in full at the same time by the same
Warrant Holder, the number of full Warrant Shares which shall be issuable upon
the exercise thereof shall be computed on the basis of the aggregate number of
Warrant Shares purchasable on exercise of the Warrants so presented. If any
fraction of a Warrant Share would, except for the provisions of this Section
13, be issuable on the exercise of any Warrant (or specified portion, thereof),
the Company shall pay an amount in cash equal to the closing price for one
share of the Common Stock on the trading day immediately preceding the date the
Warrant is presented for exercise, multiplied by such fraction.

         14.     REGISTRATION UNDER THE SECURITIES ACT OF 1933. Parker
represents and warrants to the Company that it will not dispose of the Warrant
or Warrant Shares except pursuant to (i) an effective registration statement,
or (ii) an applicable exemption from registration under the Securities Act of
1933 (the "Act"). In connection with any sale by Parker pursuant to clause (ii)
of the preceding sentence, it shall furnish to the Company an opinion of
counsel reasonably satisfactory to the Company to the effect that such
exemption from registration is available in connection with such sale.

         15.     CERTIFICATE TO BEAR LEGENDS. The Warrants shall be subject to
a stop-transfer order and the certificate or certificates therefor shall bear
the following legend by which each Warrant Holder shall be bound:

                 "THE WARRANTS REPRESENTED BY THIS CERTIFICATE AND THE SHARES
                 OF COMMON STOCK OR OTHER SECURITIES ISSUABLE UPON EXERCISE
                 THEREOF MAY NOT BE OFFERED OR SOLD EXCEPT PURSUANT TO (i) AN
                 EFFECTIVE REGISTRATION STATEMENT, OR (ii) AN APPLICABLE
                 EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT OF 1933.
                 ANY SALE PURSUANT TO CLAUSE (ii) OF THE PRECEDING SENTENCE
                 MUST BE ACCOMPANIED BY AN OPINION OF COUNSEL REASONABLY
                 SATISFACTORY TO THE COMPANY TO THE EFFECT THAT SUCH EXEMPTION
                 FROM REGISTRATION IS AVAILABLE IN CONNECTION WITH SUCH SALE."

         The Warrant Shares or other securities issued upon exercise of the
Warrants shall, unless issued pursuant to an effective registration statement,
be subject to a stop-transfer order and the certificate or certificates
evidencing any such Warrant Shares or securities shall bear the following
legend by which the Warrant Holder thereof shall be bound:

                 "THE SHARES OR OTHER SECURITIES REPRESENTED BY THIS
                 CERTIFICATE MAY NOT BE OFFERED OR SOLD EXCEPT PURSUANT TO (i)
                 AN EFFECTIVE REGISTRATION STATEMENT, OR (ii) AN





                                       13
   31
                 APPLICABLE EXEMPTION FROM REGISTRATION UNDER THE SECURITIES
                 ACT OF 1933. ANY SALE PURSUANT TO CLAUSE (ii) OF THE PRECEDING
                 SENTENCE MUST BE ACCOMPANIED BY AN OPINION OF COUNSEL TO THE
                 EFFECT THAT SUCH EXEMPTION FROM REGISTRATION IS AVAILABLE IN
                 CONNECTION WITH SUCH SALE."

         16.     REGISTRATION RIGHTS.

                 (a)      DEMAND REGISTRATION RIGHTS. The Company covenants and
         agrees with Parker and any subsequent holders of the Warrants and/or
         Warrant Shares that within sixty (60) days after receipt of a written
         request from holders of 60% in interest of the Warrants and/or Warrant
         Shares issued pursuant to this Agreement (the "Initiating Holders"),
         the Company shall file a registration statement (and use its best
         efforts to cause such registration statement to become effective under
         the Act) with respect to the offering and sale or other disposition of
         any number of Warrants and/or Warrant Shares (including any securities
         received by the Warrant Holders pursuant to Section 12 hereof) (all
         such securities, the "Registrable Securities"). The Company shall
         continuously maintain the effectiveness of such registration statement
         for the lesser of (i) 180 days after the effective date of the
         registration statement or (ii) the consummation of the distribution by
         the holders of the Registrable Securities covered by such registration
         statement (the "Termination Date"); provided, however, that if at the
         Termination Date, the Offered Securities are covered by a registration
         statement which also covers other securities and which is required to
         remain in effect beyond the Termination Date, the Company shall
         maintain in effect such registration statement as it relates to the
         Registrable Securities for so long as such registration statement (or
         any subsequent registration statement) remains or is required to
         remain in effect for any of such other securities. The Company shall
         not be required to comply with more than two requests for registration
         pursuant to this Section 16(a). The Company shall not be required to
         comply with a request for registration pursuant to this Section 16(a)
         made after December 31, 2000, provided, however, that if a request is
         properly and timely made on or prior to December 31, 2000 pursuant to
         this Section 16(a), the Company shall be required to comply with such
         request even though the registration statement does not or cannot
         become effective until after December 31, 2000 or the effectiveness of
         such registration statement is otherwise required under this Section
         16(a) to be maintained beyond December 31, 2000. All expenses of such
         registration shall be borne by the Company, except that underwriting
         commissions and expenses attributable to the Registrable Securities
         will be borne by such Warrant Holders requesting that such securities
         be offered.

         If the Initiating Holders intend to distribute the Registrable
Securities covered by their request by means of an underwriting, they shall so
advise the Company as a part of their request made pursuant to this Section
16(a). The right of any other holder to registration pursuant to this Section
16(a) shall be conditioned upon such holder's participation in such
underwriting and the inclusion of such holder's Registrable Securities in the
underwriting (unless otherwise mutually





                                       14
   32
agreed by a majority in interest of the Initiating Holders and such holder with
respect to such participation and inclusion) to the extent provided herein. A
holder may elect to include in such underwriting all or a part of the
Registrable Securities he holds. If other holders of registration rights
request inclusion in any registration statement pursuant to this Section 16(a),
such holders may be included in the underwriting conditioned on their
acceptance of the further applicable provisions of this Section 16(a). The
Company shall (together with other holders proposed to distribute their
securities through such underwriting) enter into an underwriting agreement in
customary form with a representative of the underwriter or underwriters
selected for such underwriting by a majority in interest of the Initiating
Holders. If the representative advises the Initiating Holders in writing that
marketing factors require a limitation on the number of shares to be
underwritten, then securities held by holders other than the Initiating Holders
shall be excluded from such registration to the extent so required by such
limitation.

                 (b)      PIGGY-BACK REGISTRATION RIGHTS. The Company covenants
         and agrees with Parker and any subsequent holders of the Warrants
         and/or Warrant Shares that, in the event the Company proposes to file
         a registration statement under the Act prior to December 31, 2000 with
         respect to the firm commitment offering of Common Stock (other than in
         connection with an exchange offer or a registration statement on Form
         S-4 or S-8 or other similar registration statements not available to
         register securities so requested to be included), the Company shall in
         each case give written notice of such proposed filing to (i) the
         holders of the Warrant Shares and (ii) if on or before the Expiration
         Date, the Warrant Holders, in each case at least 30 days before the
         earlier of the anticipated or the actual effective date of the
         registration statement and at least ten days before the initial filing
         of such registration statement and such notice shall offer to such
         Warrant Holders the opportunity to include in such registration
         statement such number of Warrants and/or Warrant Shares (and any
         securities received by the Warrant Holders pursuant to Section 12
         hereof) (the "Piggy-back Securities", and together with the securities
         referred to in Section 16(a) above, the "Registrable Securities") as
         they may request. Warrant Holders desiring inclusion of Piggy-back
         Securities in such registration statement shall so inform the Company
         by written notice, given within 10 days of the giving of such notice
         by the Company in accordance with the provisions of Section 18 hereof.
         The Company shall permit, or shall cause the managing underwriter of a
         proposed offering to permit, the holders of Piggy-back Securities
         requested to be included in the registration to include such
         securities in the proposed offering on the same terms and conditions
         as applicable to securities of the Company. Notwithstanding the
         foregoing, if any such managing underwriter shall advise the Company
         in writing that, in its opinion, the distribution of securities by
         holders thereof, including all or a portion of the Piggy-back
         Securities, requested to be included in the registration concurrently
         with the securities being registered by the Company would materially
         adversely affect the distribution of such securities by the Company
         for its own account, then the holders of such Warrants and/or Warrant
         Shares shall delay their offering and sale of Piggy-back Securities
         (or the portions thereof so designated by such managing underwriter)
         for such period, not to exceed 90 days, as the managing underwriter
         shall request, provided that if any other securities are included in
         such registration statement for the account of any person other than
         the Company and the





                                       15
   33
holders of Warrants and/or Warrant Shares, then such securities, including the
Warrants and/or Warrant Shares, so included shall be apportioned among holders
who wish to be included therein pro rata according to amounts so requested to
be included by each such person.  No such delay shall in any event impair any
right granted hereunder to make subsequent requests for inclusion pursuant to
the terms of this Section 16(b).  The Company shall continuously maintain in
effect any registration statement with respect to which the Piggy-back
Securities have been requested to be included (and so included) for a period of
not less than (i) 180 days after the effectiveness of such registration
statement or (ii) the consummation of the distribution by the Warrant Holders
of the Piggy-back Securities ("Piggy-back Termination Date"); provided,
however, that if at the Piggy-back Termination Date the Piggy-back Securities
are covered by a registration statement which is, or is required to remain, in
effect beyond the Piggy-back Termination Date, the Company shall maintain in
effect the registration statement as it relates to the Piggy-back Securities
for so long as such registration statement remains or is required to remain in
effect for any of such other securities.  All expenses of such registration
shall be borne by the Company, except that underwriting commissions and
expenses attributable to the Piggy-back Securities and fees and distributions
of counsel (if any) to the Warrant Holders requesting that the Piggy- back
Securities be offered will be borne by such Warrant Holders.



         (c)              OTHER MATTERS. In connection with the registration 
of Registrable Securities in accordance with Paragraph (a) or (b) above, the
Company agrees to:

                 (i)      Use its best efforts to register or qualify the
         Registrable Securities for offer or sale under state securities or
         Blue Sky laws of such jurisdictions in which the holders of such
         Warrants and/or Warrant Shares shall designate; provided, that in no
         event shall the Company be obligated to qualify to do business in any
         jurisdiction where it is not so qualified at the time of the request
         to register the Registrable Securities or to take any action which
         would subject it to general service of process in any jurisdiction
         where it is not so subject at the time of the request to register the
         Registrable Securities, and use its best efforts to do any and all
         other acts and things which may be necessary or advisable to enable
         the Warrant Holders to consummate the sale, transfer or other
         disposition of such securities in any jurisdiction;

                 (ii)     Enter into indemnity and contribution agreements,
         each in customary form, with each underwriter, if any, and each holder
         of Registrable Securities included in such registration statement;
         and, if requested, enter into an underwriting agreement containing
         customary representations, warranties, covenants, allocation of
         expenses, and customary closing conditions including, but not limited
         to, opinions of counsel, accountants' cold comfort letters, engineers'
         reports and environmental reports, with any underwriter who
         participates in the offering of Registrable Securities;





                                       16
   34

                 (iii)    Pay all expenses in connection with the registration
         of the Warrants and/or Warrant Shares under the Act and compliance
         with the provisions of clause (i) above, except to the extent
         otherwise provided in Sections 16(a) and 16(b); and

                 (iv)   List the Warrant Shares on each securities exchange on
         which the Common Stock is listed.

       In connection with the registration of Registrable Securities in
accordance with Paragraph (b) above, the Warrant Holders agree to enter into an
underwriting agreement containing customary representations, warranties,
covenants, allocation of expenses (not otherwise inconsistent with this Warrant
Agreement), and customary closing conditions, with any underwriter who
participates in the offering of Registrable Securities.

                 (d)      RESTRICTIONS ON PUBLIC SALE BY THE COMPANY AND
         WARRANT HOLDERS, The Company agrees (i) not to effect any public sale
         or distribution of any securities similar to the Registrable
         Securities or any securities convertible into or exchangeable or
         exercisable for such securities (or any option or other right for such
         securities), except for any securities that may be issued to the
         Warrant Holders pursuant Section 12 hereof, during the 15-day period
         prior to, and during the 60-day period beginning on the effective date
         of any registration statement under which the Registrable Securities
         are registered in accordance with Section 16(a) (other than as part of
         such registration).

                 (e)      RULE 144, With a view to making available to Warrant
         Holders the benefits of certain rules of the Securities and Exchange
         Commission (the "Commission") that may permit the sale of Registrable
         Securities to the public without registration, the Company hereby
         covenants and agrees to use its best efforts to: (i) file in a timely
         manner all reports and other documents required to be filed by it
         under the Act and the Securities Exchange Act of 1934 and the rules
         and regulations adopted by the Commission thereunder necessary to
         permit sales under Rule 144 under the Act, and the Company will take
         such further action to the extent required from time to time to enable
         Warrant Holders to sell Registrable Securities (whether or not any
         such securities have been the subject of a demand or piggy-back request
         under Section 16 hereof) without registration under the Act within the
         limitation of the exemptions provided by (a) Rule 144 under the Act,
         as such Rule may be amended from time to time, or (b) any similar rule
         or regulation hereafter adopted by the Commission and (ii) promptly
         furnish each Warrant Holder a copy of all such reports and documents.
         Upon the request of a Warrant Holder, the Company will deliver to such
         Warrant Holder a written statement as to whether it has complied with
         such requirements.

                 (f)      OTHER REGISTRATION RIGHTS. The Company hereby agrees
         that it shall not issue any additional registration rights with
         respect to shares of its Common Stock, warrants to purchase its Common
         Stock or securities convertible into its Common Stock, which are
         inconsistent with the provisions of this Agreement.

          17.    NO RIGHTS AS STOCKHOLDERS; NOTICE TO WARRANT HOLDERS.  Nothing
contained in this Warrant Agreement or in any of the Warrants shall be
construed as conferring upon the Warrant Holders or their transferees the right
to vote or to receive dividends or to consent or to receive notice as
stockholders in respect of any meeting of stockholders for the election of
directors of the Company or any other matter, or any rights whatsoever as
stockholders of the Company.  If, however, at any time prior to the expiration
of the Warrants and prior to their exercise, any of the following events shall
occur:

                 (a)      the Company shall declare any dividend payable in any
         securities upon its shares of Common Stock or make any distribution
         (other than a cash dividend) to the holders of its shares of Common
         Stock; or

                 (b)      the Company shall offer to the holders of its shares
         of Common Stock any additional shares of Common Stock or securities
         convertible into or exchangeable for shares of Common Stock or any
         right to subscribe to or purchase any thereof; or

                 (c)      a dissolution, liquidation or winding up of the
         Company (other than in connection with a consolidation, merger, sale,
         transfer or lease or all or substantially all of its property, assets,
         and business as an entirety) shall be proposed,

then in any one or more of said events the Company shall (a) give notice in
writing of such event to the Warrant Holders as provided in Section 21 hereof
and (b) if there are more than 100 Warrant Holders, cause notice of such event
to be published once in The Wall Street Journal (national edition), such giving
of notice and publication to be completed at least 15 days prior to the date
fixed as a record date or the date of closing the transfer books for the
determination of the stockholders entitled to such dividend, distribution, or
subscription rights, or for the determination of stockholders entitled to vote
on such proposed dissolution, liquidation or winding up. Such notice shall
specify such record date or the date of closing the transfer books, as the case
may be.  Failure to publish, mail or receive such notice or any defect therein
or in the publication or mailing thereof shall not affect the validity of any
action taken in connection with such dividend, distribution or subscription
rights, or such proposed dissolution, liquidation or winding up.



         18.     EXPENSES.  The Company shall pay all legal and other reasonable
out-of-pocket expenses of the Warrant Holders and of their counsel, subject to
a limit of $5,000.

         19.     RIGHTS TO INFORMATION. The Company, in accordance with Section
16(c) above, will provide to all Warrant Holders and to all holders of Warrant
Shares, on a timely basis, copies of all documents and reports filed with the
Commission and annual and quarterly financial statements, prepared in
accordance with GAAP; and additionally will provide upon reasonable request any
other pertinent financial information.

RELATED DOCUMENTS SHALL BE DEEMED TO BE CONTRACTS MADE UNDER AND SHALL BE

WITHOUT GIVING EFFECT TO PRINCIPLES OF CONFLICTS OF LAW.



         22.     SUPPLEMENTS AND AMENDMENTS.  The Company and the Warrant
Holders may from time to time supplement or amend this Warrant Agreement in
order to cure any ambiguity or to correct or supplement any provision contained
herein which may be defective or inconsistent with any other provision herein,
or to make any other provisions in regard to matters or questions arising
hereunder which the Company and the Warrant Holder may deem necessary or
desirable and which shall not be inconsistent with the provisions of the
Warrants and which shall not adversely affect the interests of the Warrant
Holders.  Any amendment to this Warrant Agreement may be effected with the
consent of Warrant Holders of at least a majority of the total then outstanding
Warrants (for this purpose Warrant Shares shall be deemed to be Warrants in the
proportion that Warrant Shares are then issuable upon the exercise of
Warrants); provided that, any amendment which shall have the effect of
materially adversely affecting the interests of any Warrant Holder shall not be
effective with respect to such Warrant Holder if such Warrant Holder shall not
have consented thereto.


         23.     SURVIVAL OF REPRESENTATIONS, WARRANTIES AND COVENANTS.  All
representations and warranties of the Company and all covenants and agreements
made herein shall survive the execution and delivery of this Warrant Agreement
and the Warrants and shall remain in force and effect until the Expiration

         25.     MERGER OR CONSOLIDATION OF THE COMPANY.  So long as this
Warrant Agreement remains in effect, the Company will not merge or consolidate
with or into, or sell, transfer or lease all or substantially all of its
property to, any other corporation unless the successor or purchasing
corporation, as the case may be (if not the Company), shall expressly assume,
by supplemental agreement executed and delivered to the Warrant Holders, the
due and punctual performance and observance of each and every covenant and
condition of this Warrant Agreement to be performed and observed by the
Company.

         26.     BENEFITS OF THIS WARRANT AGREEMENT.  Nothing in this Warrant
Agreement shall be construed to give to any person or corporation other than
the Company and the Warrant Holders, any legal or equitable right, remedy or
claim under this Warrant Agreement, but this Warrant Agreement shall be for the
sole and exclusive benefit of the Company and the holders of the Warrants and
Warrant Shares.

         27.     CAPTIONS. The captions of the sections and subsections of this
Warrant Agreement have been inserted for convenience and shall have no
substantive effect.

         28.     COUNTERPARTS. This Warrant Agreement may be executed in any
number of counterparts, each of which so executed shall be deemed to be an
original; but such counterparts together shall constitute but one and the same
instrument.

         IN WITNESS WHEREOF, the parties hereto have caused this Warrant
Agreement to be duly executed on the day, month and year first above written.
