                               ROYALTY AGREEMENT
                               -----------------

ROYALTY AGREEMENT, made this May, 2000, by and between Marine Shuttle Operations
AS, a Corporation having its principal office and place of business at
Luramyrveien 29, P.O.BOX 1137, N-4301 Sandnes (hereinafter referred to as MSO);
and Marine Shuttle Operations Inc, a Company organized and existing under the
Laws of Nevada, USA, having its principle place of business at 4410 Mountrose
Boulevard, Houston. Texas 77066, USA (hereinafter referred to as MSO Inc);

and

Gunnar Foss, Mezenplein 11, 2566Z6, den Haag, The Netherlands (hereinafter
referred to as Foss).

1.    Background
      ----------

      Foss has entered into Addendum No. 1 to Agreement Regarding Intellectual
      Property, which Addendum relates specifically to the waiver by Foss in
      favour of MSO AS of Intellectual Property Rights to the Offshore Shuttle
      Concept.

      The purpose of this Agreement is to stipulate the Royalty Payments (the
      Royalty Payments) to which Foss shall be entitled in respect of the said
      Addendum No. 1.

      Both parties to this Agreement recognize that the application of the
      Offshore Shuttle Concept has to date not generated any revenues.

      Both parties also recognise that certain work will have to be performed by
      Foss also in the future in order to maintain the Intellectual Property
      Rights to the Offshore Shuttle Concept. The corresponding undertakings by
      Foss are outlined in Article 3 of this Royalty Agreement.

2.    Royalty Payments
      ----------------

      Subject to Article 6 hereof, the parties agree that Foss shall receive
      annual royalty payments (the Royalty Payments) in the amount of USD
      120,000,- (USD -One hundred and twenty thousand-) to be paid in twelve
      monthly installments for a period of 10 consecutive years from the date of
      fulfillment of the conditions contained in Article 3 of the aforementioned
      Addendum No. 1.

      Royalty Payments shall be made without demand, and the first payment shall
      be made on the first day of the first calendar month following the
      completion of the fulfillment of the conditions referred to in the
      foregoing paragraph of this Article.

      In the event that Foss should decease at any time during the 10
      year-period referred to in the first paragraph of this Article 2, then his
      Estate shall be entitled to receive the Royalty Payments for the remainder
      of that 10 year-period. The Estate of Mr. Foss shall in respect of Royalty
      Payments be deemed to be limited to such heirs as the spouse and children,
      inclusive of grandchildren, of Foss.

      All Royalty Payments under this Agreement shall be made in gross amounts,
      without deductions of any kind. Any and all taxes, duties or suchlike
      which may be attracted to the Royalty Payments under this Agreement shall
      be the sole responsibility of Foss or his Estate.

3.    Confidentiality: Maintenance of Intellectual Property Rights
      ------------------------------------------------------------

      Foss shall assist MSO AS in the maintenance of the Intellectual Property
      Rights waived to the benefit of MSO AS in the Agreement Regarding
      Intellectual Property and its Addendum No. 1.

      The following shall apply with regard to the maintenance services provided
      by Foss:

      a)    The work shall consist in the maintenance and further development of
            the Offshore Shuttle Concept being covered by the Intellectual
            Property Rights as provided in Article 6 of the Agreement Regarding
            Intellectual Property Rights.

      b)    During the period following the date of signature of this Royalty
            Agreement and until such time as Offshore Shuttle No. 1 has been
            built, tested and commissioned, and for a reasonable period
            thereafter, such period not to exceed 3 years as from the date of
            the signature of the Royalty Agreement, Foss will be available to
            MSO to do maintenance work for a maximum of 30 hours per week,
            except during periods of illness and holiday.

      c)    After the expiry of the time frame referred to in litre b) and
            during the remaining time of the 10 year period referred to in the
            first paragraph of Article 2, Foss shall make himself available for
            MSO AS not more than 10 hours per month, unless otherwise agreed.

<PAGE>
                                       3

      d)    Foss shall report directly to the Board of Directors of MSO AS and
            MSO Inc., or to individuals nominated by the said directors in his
            work relative to the maintenance of Intellectual Property Rights as
            set forth in this Article 3.

      e)    Foss shall have the right to terminate the maintenance work for MSO
            AS by 30 days' written notice. He shall not receive any Royalty
            Payments as from the effective date of the termination. In such
            case, also this Royalty Agreement shall become terminated from the
            same date, with no effect on the Addendum No. 1 to the Agreement
            regarding Intellectual Property Rights.

4.    Confidentiality: Protection of Trade Secrets
      --------------------------------------------

      All memoranda, notes, records or other documents made or compiled by Foss
      or made available to him prior to or subsequent to the execution of this
      Agreement, relating wholly or in part to the Offshore Shuttle-Concept,
      shall be deemed to be Trade Secrets.

      Foss undertakes to treat all Trade Secrets with the utmost confidentiality
      against all third parties and will not divulge or make known any such
      Trade Secret without the prior written consent of the MSO.

      Foss further undertakes to keep such Trade Secrets in safe keeping in
      accordance with guidelines which may from time to time may be issued by
      MSO, provided, however, that such guidelines do not cause Foss to incur
      costs and/or burdens substantially different from those reasonably
      envisaged by him at the time of execution of this Royalty Agreement.

5.    Non-Competition
      ---------------

      From the date for execution of this Agreement and for the duration of the
      10 year-period referred to in the first paragraph of Article 2 hereof,
      Foss will not compete with, or directly or indirectly, own, manage,
      operate, control, loan money to, or participate in the ownership,
      management, operation or control of, or be connected with as a director,
      officer, employee, partner, consultant, agent, independent contractor or
      otherwise, or acquiesce in the use of his name in any other business
      organization which competes with MSO or its subsidiaries or sister
      companies in any geographical area in which the Offshore Shuttle Concept
      or any development thereof may be applied.

      It is further agreed that Foss shall make available to MSO any and all
      such Trade Secrets as referred to in Article 3 hereof, inclusive of such
      unrecorded knowledge that may be available to Foss, which MSO from time to
      time may require.

6.    General
      -------

      In the event that Foss significantly should fail to observe any of his
      obligations and/or undertakings as specified in Articles 3, 4, 5 and 6
      hereof, then Foss shall have forfeited his right to receive Royalty
      Payments from MSO, and MSO shall be entitled to discontinue any and all
      payments of Royalty Payments from the date of such failure by Foss. The
      same will apply in the event that Foss is in material breach of any other
      of his explicit or implied contractual undertakings towards MSO or
      companies directly or indirectly contracted by MSO.

                                 LOAN AGREEMENT

      THIS LOAN AGREEMENT (this "Agreement") is dated as of July 26, 2000,
between Mr. Holger Timm, an individual with an address at Trabener Stra(beta)e
12, 14193 Berlin, Germany ("Lender"), and Marine Shuttle Operations Inc., a
Nevada corporation with an address at Luramyrveien 29, 4391 Sandnes, Norway
("Borrower").

                             W I T N E S S E T H :

      WHEREAS, Borrower desires to borrow money from Lender, and Lender desires
to loan money to Borrower, subject to the terms and provisions of this
Agreement;

      NOW THEREFORE, for and in consideration of the premises, and other good
and valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, the parties agree as follows:

      1. Loan. Lender will provide the Borrower with a loan in the amount of up
to $1,500,000 (the "Loan"). Borrower and Lender agree that $450,000 has
heretofore been advanced under the Loan and that Schedule 1 attached hereto is a
complete and accurate statement of advances of principal of the Loan. The Loan
shall be evidenced by Borrower's promissory note in the form attached hereto as
Exhibit A (the "Note"). The Loan proceeds will be advanced to Borrower in
minimum $200,000 increments upon ten (10) business days written notice of demand
by Borrower; provided, however, Lender is not required to advance more than
$500,000 in any single month. Advances shall be limited in the aggregate to the
stated principal amount of the Loan; the Loan is not a revolving line of credit.
The following are conditions precedent to any advance hereunder (except to the
extent and in the manner expressly waived by Lender, and any such conditions
waived by Lender may be reimposed as a condition of subsequent advances):

            (a)   Borrower shall have executed and delivered the Note to the
Lender.

            (b)   All representations and warranties made by Borrower in this
Agreement shall be true, complete and correct on and as of the date of the
making of any advance hereunder as though such representations and warranties
were made anew on such date.

            (c)   There shall not have occurred and be continuing any default in
the performance or observance of any of the material covenants, agreements, or
conditions to be performed or observed by Borrower under this Agreement or the
Note.

      2.    Interest. The Loan shall bear interest at a rate of seven and one
half percent (7.5%) per annum.

      3.    Repayment of Loan. The outstanding principal balance of the Loan and
accrued and unpaid interest thereon shall be due and payable on December 31,
2000, unless sooner converted or paid as provided in the Note.

      4.    Representations, Warranties, and Covenants of Borrower. Borrower
represents, warrants, and covenants to Lender as follows:

<PAGE>

            (a)   Corporate Organization and Good Standing. Borrower is a
corporation duly organized, validly existing and in good standing under the laws
of its jurisdiction, with all requisite corporate power and authority to own,
operate and lease its properties and to carry on its business as it is now being
conducted. Borrower is qualified and in good standing to do business in all
jurisdictions where its business or ownership or leasing of property or assets
requires such qualification, except where the failure to be so qualified would
not have a material adverse effect on Borrower's business, operations, financial
condition, properties, or assets (a "Material Adverse Effect").

            (b)   Authority. Borrower has all requisite corporate power and
authority to execute and deliver this Agreement and to perform its obligations
hereunder and to consummate the transactions contemplated hereby. The execution
and delivery of this Agreement by Borrower and the consummation by Borrower of
the transactions contemplated hereby have been duly authorized by its board of
directors or similar governing body, if applicable, and no other corporate or
shareholder proceedings on the part of Borrower are necessary to authorize this
Agreement or to consummate the transactions contemplated hereby. This Agreement
has been duly executed and delivered by Borrower and is a valid and binding
obligation of Borrower.

            (c)   Actions and Proceedings. There is no claim, arbitration,
grievance, action, suit, investigation, bankruptcy, insolvency, rearrangement or
similar actions or proceedings, whether voluntary or involuntary, by or before
any court, arbiter, administrative agency or other governmental authority, now
pending or threatened against Borrower, or which involves any of the business,
properties or assets of Borrower that, if adversely resolved or determined,
would have a Material Adverse Effect.

      5.    Representations, Warranties, and Covenants of Lender. Lender
represents, warrants, and covenants to Borrower as follows:

            (a)   Offshore Transaction. (i) Lender is not a U.S. person ("U.S.
Person") as that term is defined in Regulation S; (ii) the Note was not offered
to Lender in the United States; (iii) at the time of execution of this Agreement
and the time of any offer to Lender to purchase the Note hereunder, Lender was
physically outside the United States; (iv) Lender is purchasing the Note for his
own account and not on behalf of or for the benefit of any U.S. Person, and the
sale and resale of the Note have not been prearranged with any U.S. Person or
buyer in the United States; and (v) Lender is not an underwriter, dealer,
distributor, or other person who is participating, pursuant to a contractual
arrangement, in the distribution of the Note offered or sold in reliance on
Regulation S.

            (b)   Lender's Independent Investigation. Lender, in subscribing for
the Note hereunder, has relied solely upon an independent investigation made by
him and his representatives, if any. Prior to the date hereof, Lender has been
given the opportunity to ask questions of, and receive answers from,
representatives of Borrower. Lender also has been given access to and the
opportunity to examine all books and records of Borrower, and all material
contracts and documents of Borrower which have been filed as exhibits to
Borrower's filings made under the Act and the Securities Exchange Act of 1934,
as amended

                                       2
<PAGE>

(the "Exchange Act"). In making his investment decision to purchase the Note,
Lender is not relying on any oral or written representations or assurances from
Borrower or any other person other than as set forth in this Agreement. Lender
has received and reviewed Borrower's Annual Report on Form 10-K for the year
ended December 31, 1999, Borrower's Form 10-Q for the quarter ended March 31,
2000, and Borrower's Offering Circular dated April 27, 2000 (collectively the
"Disclosure Documents"). Lender has such experience in business and financial
matters that he is capable of evaluating the risk of his investment and
determining the suitability of his investment.

            (c)   Accredited Investor; Investment Knowledge. Lender is an
accredited investor as defined in Rule 501 of Regulation D promulgated under the
Act. Lender has sufficient knowledge and experience in financial and business
matters so as to be capable of evaluating the risks and merits of Lender's
investment in Borrower. Lender is knowledgeable about the affairs of Borrower.

            (d)   Lender's Economic Risk. Lender understands and acknowledges
that an investment in the Note involves a high degree of risk. Lender
acknowledges that there are limitations on the liquidity of the Note. Lender
represents that Lender is able to bear the economic risk of an investment in the
Note, including a possible total loss of investment. Lender has adequate means
of providing for Lender's current needs and contingencies, and Lender is able to
afford to hold the Note for an indefinite period. Further, Lender has no present
need for liquidity in the Note and Lender is willing to accept such investment
risks.

            (e)   No Government Recommendation or Approval. Lender understands
that no United States federal or state agency, or similar agency of any other
country, has reviewed, approved, passed upon, or made any recommendation or
endorsement of Borrower or the purchase of the Note.

            (f)   Borrower's Reliance on Representations of Lender. Lender
understands that the Note is being offered and sold to him in reliance on
specific exemptions from the registration requirements of U.S. securities laws,
and that Borrower is relying upon the truth and accuracy of the representations,
warranties, agreements, acknowledgments, and understandings of Lender set forth
herein in order to determine the applicability of such exemptions and the
suitability of Lender to acquire the Note.

            (g)   Shares Not Registered Under the Act. Lender understands that
(i) the offer and sale of the Note have not been registered under the Act or the
laws of any other jurisdiction ("Foreign Acts"), and are being offered and sold
pursuant to Regulation S based in part upon the representations of Lender
contained herein; (ii) the Note must be held indefinitely unless a subsequent
disposition thereof is registered under the Act or is made pursuant to
Regulation S or an exemption from such registration; (iii) the certificate
evidencing the Note shall bear a legend to such effect, and (iv) Borrower will
make a notation on its transfer books to such effect.

            (h)   Investment Intent. Lender is acquiring the Note for his own
account for investment, not as a nominee and not with a view to the distribution
thereof. Lender has no present plan or intention to sell the Note at any
predetermined time, and has made no predetermined arrangements to sell the Note.

                                       3
<PAGE>

            (i)   Lender's Power and Authority. Lender has the full power and
authority to execute, deliver, and perform this Agreement. This Agreement, when
executed and delivered by Lender, will constitute a valid and legally binding
obligation of Lender, enforceable in accordance with its terms.

            (j)   No Tax Advice From Borrower or Its Agents. Lender has had an
opportunity to review with his own tax advisors the foreign, federal, state and
local tax consequences of this investment, and the transactions contemplated by
this Agreement. Lender is relying solely on such advisors and not on any
statements or representations of Borrower or any of its agents and understands
that Lender (and not Borrower) shall be responsible for Lender's own tax
liability that may arise as a result of this investment or the transactions
contemplated by this Agreement.

            (k)   No Legal Advice from Borrower or Its Agents. Lender
acknowledges that he has had the opportunity to review this Agreement and the
transactions contemplated by this Agreement with his own legal counsel. Lender
is relying solely on such counsel and not on any statements or representations
of Borrower or any of its agents for legal advice with respect to this
investment or the transactions contemplated by this Agreement, except for
representations, warranties and covenants set forth herein.

            (l)   No Scheme to Evade Registration. Lender's acquisition of the
Note 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.

            (m)   No Direct Selling Efforts. To Lender's knowledge, neither
Borrower, nor any person acting for Borrower, has conducted any "directed
selling efforts" in the United States as the term is defined in Regulation S,
which in general, means any activity undertaken for the purpose of, or that
could reasonably be expected to have the effect of, conditioning the market in
the United States for any of the Note being offered in reliance on Regulation S.
Such activity includes, without limitation, the mailing of printed material to
investors residing in the United States, the holding of promotional seminars in
the United States, and the placement of advertisements with radio or television
stations broadcasting in the United States or in publications with a general
circulation in the United States, that refers to the offering of the Note in
reliance on Regulation S.

      6.    Resales of Note by Lender; Legends.
            ----------------------------------

            (a)   Resales of Note. Lender acknowledges, covenants, and agrees
that Lender may not and will not resell the Note unless such resale is made
pursuant to an exemption from registration under the Act, pursuant to an
effective and current registration statement under the Act, or pursuant to
Regulation S. Lender shall cause a transferee of the Note to execute, prior to
any such transfer, an agreement containing provisions substantially similar to
Sections 5 and 6 hereof.

                                       4
<PAGE>

            (b)   Legend. To insure compliance with the provisions of the Act,
the Note shall bear a legend (the "Regulation S Restrictive Legend")
substantially as follows:

            "THE ISSUANCE OF THE SECURITIES EVIDENCED HEREBY HAS NOT BEEN
            REGISTERED UNDER THE U.S. SECURITIES ACT OF 1933, AS AMENDED (THE
            "ACT"). THE SECURITIES WERE ISSUED PURSUANT TO A SAFE HARBOR FROM
            REGISTRATION UNDER REGULATION S ("REGULATION S") PROMULGATED UNDER
            THE ACT. THE SECURITIES MAY NOT BE OFFERED, SOLD, OR OTHERWISE
            TRANSFERRED UNLESS SUCH OFFERS, SALES, AND TRANSFERS ARE REGISTERED
            UNDER THE ACT, ARE MADE PURSUANT TO AN AVAILABLE EXEMPTION FROM THE
            REGISTRATION REQUIREMENTS OF THE ACT, OR ARE MADE PURSUANT TO
            REGULATION S. FURTHERMORE, HEDGING TRANSACTIONS INVOLVING THE
            SECURITIES MAY NOT BE CONDUCTED UNLESS IN COMPLIANCE WITH THE ACT."

      7.    Covenants by Lender. Lender covenants that he will not knowingly
make any sale, transfer, or other disposition of the Note, or engage in hedging
transactions with respect to the Note, in violation of the Act (including
Regulation S), the Exchange Act, any applicable Foreign Acts, or the rules and
regulations promulgated under any of the foregoing.

      8.    Covenants of Borrower. Borrower will refuse to register any transfer
of the Note not made in accordance with Regulation S, pursuant to an effective
registration statement under the Act, or pursuant to an available exemption from
registration.

      9.    Miscellaneous.
            -------------

            (a)   Notice. All notices, requests, demands and other

over-night delivery service, with costs for "next day" delivery prepaid,
addressed in either case to the parties at their respective addresses first set
forth above (or to such other address as such party may from time to time
designate to the other by like written notice).

            (b)   Governing Law and Choice of Forum. This Agreement and the Note
will be governed by and construed in accordance with the laws of the State of
Texas. The parties agree that any appropriate court located in Texas will have
exclusive jurisdiction of any case or controversy arising under or in connection

or controversy. The parties expressly consent to personal jurisdiction and venue
in such courts.

            (c)   Entire Agreement/Amendment. This Agreement embodies the entire
agreement of the parties hereto relating to the subject matter hereof and
supersedes all oral agreements, and to the extent inconsistent with the terms

            (d)   Severability. In the event any provision (or any part of any
provision) contained in this Agreement shall for any reason be finally held by a
court of competent jurisdiction to be invalid, illegal or unenforceable in any
respect, such invalidity, illegality or unenforceability shall not affect any
other provision (or remaining part of the affected provision) of this Agreement;
but this Agreement shall be construed as if such invalid, illegal or
unenforceable provision (or part thereof) had never been contained herein, but
only to the extent it is invalid, illegal or unenforceable.

            (e)   Captions and Section Headings. Captions and section headings
used herein are for convenience only and are not a part of this Agreement and
will not be used in construing it.

$1,500,000                                                 July 26, 2000

      FOR VALUE RECEIVED, Marine Shuttle Operations Inc., a Nevada corporation
with an address at c/o Marine Shuttle Operations AS, Luramyrveien 29, 4391
Sandnes, Norway ("Borrower"), does hereby promise to pay to the order of Mr.
Holger Timm or any other holder hereof ("Lender"), at Trabener Stra(beta)e 12,
14193 Berlin, Germany or at such other place as Lender may designate by written
notice to Borrower, the principal sum of ONE MILLION FIVE HUNDRED THOUSAND
DOLLARS ($1,500,000) (or such lesser amount as shall be advanced hereunder),
together with interest thereon as provided below, on or before December 31, 2000
(unless sooner converted as provided below). This Note is being issued pursuant
to that certain Loan Agreement, of even date herewith, by and between the
Borrower and Lender (the "Loan Agreement").

      1.    Acknowledgement of Receipt of Funds. As of the date of this Note,
Borrower has received aggregate advances of $450,000 in principal funds (not
including interest or any other sums payable hereunder) from Lender pursuant to
the terms of this Note.

      2.    Interest. Interest will accrue on the outstanding principal amount
of this Note at the rate of seven and one half percent (7.5%) per annum from the
date of each advance, and until all amounts outstanding under this Note have
been paid in full.

      3.    Payments. Interest, principal and all other sums payable hereunder
(collectively, the "Obligations") shall be payable, without any offset,
reduction, counterclaim or recoupment whatsoever, in lawful money of the United
States of America which shall be legal tender in payment of all debts and dues,
public and private, at the time of payment.

      4.    Conversion.
            ----------

            (a)   Any or all of the Obligations outstanding at any particular
time may be converted by Lender into that number of shares (rounded up to the
next whole share) of Borrower's common stock, par value $0.001 per share (the
"Common Stock"), determined by dividing the amount of the Obligation to be
converted by the Conversion Price. The Conversion Price shall equal 80% of the

<PAGE>

Average Price (as hereinafter defined); provided, however, in no event shall the
Conversion Price be less than $0.70, subject to adjustment as provided below
(the "Floor Price"). Each conversion shall be effected by delivering to Borrower
a duly executed copy of the Conversion Notice attached hereto, and such other
documents that may be reasonably be requested by Lender. Promptly after receipt
of the Conversion Notice, Borrower shall issue and deliver to Lender a stock
certificate or certificates for the number of shares of Common Stock to which
Lender shall be entitled. As used herein, Average Price shall mean the average
of the last sale prices of the Common Stock (or in case no such reported sale
takes place on a particular day, the average of the last reported bid and asked
prices on such day) on NASDAQ (or on the principal national securities exchange
on which the Common Stock is admitted to trading or listed), or if not listed or
admitted to trading on NASDAQ or a national securities exchange, as reported by
Pink Sheets, LLC or other similar organization, for the five (5) trading days
immediately preceding the date upon which Lender sends, by facsimile
transmission or otherwise, the Conversion Notice to Borrower at its executive
offices.

            (b)   If Borrower shall, at any time or from time to time, declare
and pay to the holders of Common Stock a dividend in shares of Common Stock, or
Borrower shall subdivide the outstanding shares of Common Stock into a greater
number of shares of Common Stock, or combine the outstanding shares of Common
Stock into a smaller number of shares of Common Stock, then the Floor Price
shall be adjusted so that the same shall equal the price determined by
multiplying the Floor Price in effect immediately prior to the happening of such
event by a fraction, the numerator of which shall be the number of shares of
Common Stock issued and outstanding immediately prior to the happening of such
event and the denominator of which shall be the number of shares of Common Stock
issued and outstanding immediately after the happening of such event. Such
adjustment shall become effective immediately after the opening of business of
the day following the record date, in the event of a stock dividend, or the day
upon which the subdivision or combination becomes effective, as the case may be.

      5.    Advances. Advances by Lender under this Note shall be made only as
provided in, and are subject to the terms and conditions -------- of, the Loan
Agreement.

      6.    Application of Payments. All payments shall be applied first on
account of Lender's costs of collection (including, without limitation,
reasonable attorneys' fees and expenses), if any, then to accrued and unpaid
interest, and the balance to the reduction of principal. For the purposes of
computing interest on the debt evidenced hereby, interest shall be calculated on
the basis of a year consisting of three hundred sixty (360) days, and shall be
charged on the basis of the actual number of calendar days that the principal
amount advanced remains unpaid to Lender.

      7.    Default; Remedies. Upon the happening of any of the following
events, the Obligations shall become due and payable at the option of Lender
upon notice to Borrower, and Lender may exercise any or all additional remedies
provided under this Note:

            (a)   if Borrower shall fail to make payment when due of any
      Obligation hereunder, and such failure to comply shall continue for a
      period of ten (10) days after Lender shall have given Borrower written
      notice thereof;

                                       2
<PAGE>

            (b)   if any warranty or representation made by Borrower in this
      Note or the Loan Agreement shall be false or misleading in any material
      adverse respect; or any financial statement, information or certification
      submitted to Lender shall be false or misleading in any material adverse
      respect; or Borrower shall fail to comply with any material term,
      condition or covenant contained in this Note or the Loan Agreement, if, in
      each instance, the circumstances giving rise to any false or misleading
      condition or such failure to comply shall continue for a period of
      fourteen (14) days after Lender shall have given Borrower written notice
      thereof;

            (c)   if Borrower shall make a general assignment for the benefit of
      creditors; or if a receiver or trustee shall be appointed for all or any
      portion of Borrower's assets; or if there shall be filed by Borrower any
      petition or application for relief under the Bankruptcy Code; or

            (d)   if there shall be filed against Borrower any petition or
      application for relief under the Bankruptcy Code which is not discharged
      or bonded off to the satisfaction of Lender within sixty (60) days, or if
      Borrower consents to any order for relief.

      Failure of Lender to exercise the option to accelerate payment or exercise
other remedies in the event of any default shall not constitute a waiver of the
right to exercise the same in the event of any subsequent default.

      8.    Prepayment. The privilege is reserved to Borrower to prepay the
indebtedness evidenced hereby, in whole or in part, at any time or from time to
time, without prepayment premium or penalty.

      9.    Waivers. Borrower hereby waives presentment, protest and demand,
notice of protest and notice of dishonor of this Note.
