ITEM 1.01  ENTRY INTO A MATERIAL DEFINITIVE AGREEMENT

     On March 29, 2006, Odyssey Marine Exploration, Inc. (the "Company")
entered into an Amended and Restated Revolving Credit Agreement with

by the custodian from 10,000 to 15,000 coins; revised certain loan covenants
for reporting; and increased certain thresholds for notification and approval
by Mercantile Bank.  There is currently approximately $12,000 outstanding
under this line of credit.

EXHIBIT 10.1

                AMENDED AND RESTATED REVOLVING CREDIT AGREEMENT

     THIS AMENDED AND RESTATED REVOLVING CREDIT AGREEMENT, made this 29th day
of March, 2006, by and between ODYSSEY MARINE EXPLORATION, INC., a Nevada
corporation, whose address is 5215 West Laurel Street, Tampa, Florida 33607
("Borrower"), and MERCANTILE BANK, whose address is 2307 West Kennedy
Boulevard, Tampa, FL 33609 ("Lender").

                             W I T N E S S E T H:

     WHEREAS, Borrower and Lender previously entered into that certain
Revolving Credit Agreement dated April 21, 2005 (as it may be amended,
supplemented or modified from time to time, the "Original Loan Agreement"),
pursuant to which the Lender made a revolving credit loan (the "Original
Loan") in the maximum principal amount of $6,000,000.00 to Borrower; and

     WHEREAS, Borrower and Lender desire to amend and restate in its entirety
the Original Loan Agreement pursuant to the terms hereof; and

     WHEREAS, certain capitalized terms used in this Agreement are defined in
Section 10 hereof;

     NOW, THEREFORE, it is agreed as follows:

     1.   Revolving Credit Loan.

          (a)  Revolving Credit Commitment.  Subject to the terms and
conditions hereof, Lender agrees to make Advances to Borrower from time to
time during the Commitment Period in an aggregate principal amount at any one
time outstanding not to exceed THREE MILLION AND 00/100 DOLLARS
($3,000,000.00) (the "Commitment").  As long as no Event of Default has
occurred hereunder and no Default has occurred that, with the passage of
time, the giving of notice, or both, shall constitute an Event of Default
hereunder, Borrower shall be entitled to borrow, repay or prepay and
reborrow, by delivering to Lender a Draw Request in the form of Exhibit "A"
attached hereto ("Draw Request").

          (b)  Revolving Credit Note.  The Revolving Credit Loan shall be
evidenced by a promissory note of Borrower payable to the order of Lender
substantially in the form of Exhibit "B" attached hereto ("Revolving Credit
Note").

          (c)  Interest.  The Revolving Credit Loan shall accrue interest as
provided in the Revolving Credit Note.

          (d)  Borrower's Loan Account.  Lender shall enter in its records of
this Revolving Credit Loan all Advances under the Revolving Credit Loan and
all payments made by or on behalf of Borrower on account thereof.  Any
payments shall be credited first to payment of any late charges, fees or
expenses, if any, then to accrued and unpaid interest and the balance, if
any, ("Credit") to principal.  Lender shall provide Borrower a monthly
accounting of transactions under the Revolving Credit Loan.  Each such

Page 1

accounting shall be deemed final, binding and conclusive upon Borrower in all
respects as to all matters as reflected therein, unless Borrower, within
thirty (30) days after the date the accounting is rendered, notifies Lender
in writing of any objections, describing the basis for such objections with
specificity.  In such event, only those items expressly objected to in the
notice shall be deemed disputed by Borrower.

          (e)  Revolving Credit Commitment Period.  The Commitment Period
shall terminate on April 21, 2008 (the "Termination Date") unless Borrower
shall earlier terminate the Commitment.  Lender shall review its Commitment
hereunder annually, with the first review to occur on or about the first
anniversary hereof.

          (f)  Termination or Reduction of Commitment.  Borrower shall have
the right, upon not less than five (5) Business Days' written notice to
Lender, to terminate or reduce the Commitment at any time, provided that any
notice of termination shall be accompanied by payment in full of the
Revolving Credit Loan and the Advances outstanding thereunder and provided
that any notice of reduction shall be accompanied by payment in full of the
Revolving Credit Loan balance that exceeds the reduced Commitment.

          (g)  Unused Line Fee.  Borrower hereby agrees to pay Lender an
unused line fee at a rate equal to one-fourth of one percent (0.25%) per
annum calculated upon the amount by which $3,000,000.00 exceeds the average
daily principal balance of the outstanding Advances during the immediately
preceding calendar quarter (or part thereof) while this Agreement is in
effect and for so long thereafter as any of the Advances are outstanding,
which fee shall be payable quarterly in arrears.

          (h)  Mandatory Payments.  In the event that Lender shall notify
Borrower that the current Revolving Credit Loan balance exceeds the
Commitment, Borrower shall immediately repay the Revolving Credit Loan by the
amount of such excess.

          (i)  Permissive Prepayments.  Borrower may, at any time and from
time to time, pay or prepay the Revolving Credit Loan, in whole or in part,
without payment of any premium or penalty.

          (j)  Use of Proceeds.  The proceeds of the Revolving Credit Loan
shall be used by Borrower for working capital requirements.

     2.   Security.  As security for the Loan, Borrower shall at Closing
execute and deliver to Lender the Security Agreement, granting to Lender a
lien and security interest on, in and to all of the assets described on
Exhibit "D" which is attached hereto and made a part hereof, now owned or
hereafter acquired, and the proceeds and products thereof ("Collateral") free
of all claims, liens and encumbrances except for claims, liens and
encumbrances, if any, listed on Exhibit "D," except for liens and
encumbrances in favor of Lender, and except for Permitted Liens (as defined
below).  Borrower authorizes the filing by Lender, in form and substance
satisfactory to Lender, of UCC-1 financing statements describing the
Collateral and determined by the Lender to be desirable to perfect the liens
and security interests referred to in this paragraph.


Page 2

     As further security for the Loan, Borrower hereby assigns and grants to
Lender a security interest in and to all property of Borrower which is or may
hereafter be in Lender's possession (by deposit, assignment, purchase or
otherwise) in any capacity including but not limited to all monies owed or to
be owed by Lender to Borrower, deposits (whether or not Lender has possession
of any certificate of deposit or other indicia of ownership), and stocks,
bonds or other securities held in any securities trading account, custodial
account or otherwise; and with respect to all such property, Lender shall
have the same rights as it has to any Collateral.

     As further security for the Loan, Borrower shall at Closing execute and
deliver to Lender the Negative Pledge Agreement, whereby Borrower will
covenant and agree that no claims, liens or encumbrances of any kind shall be
placed upon vessels owned by the Borrower.

     The release of any Coins from Lender's security interest in connection
with sales of Coins by Borrower in the ordinary course of its business shall
be governed by and made in accordance with the terms and conditions of the
Security Agreement.

     3.   Representations and Warranties of Borrower.  In order to induce
Lender to make the Loan, Borrower makes the following representations and
warranties:

          (a)  Corporate Status.  Borrower (i) is duly incorporated, validly
existing and in good standing under the laws of the State of Nevada; (ii) has
qualified as a foreign corporation to transact business and is in good
standing in Florida; (iii) has qualified as a foreign corporation to transact
business and is in good standing in every other jurisdiction in which any
Collateral is located or the nature of its business or properties makes such
qualification necessary or Borrower owns or leases material properties or
conducts material business; (iv) has the requisite corporate power and
authority to own, pledge and operate its properties, to lease the properties
it operates under lease and to conduct its business as it is now being
conducted; and (v) is in compliance in all material respects with its
articles of incorporation and bylaws.

          (b)  Authorization; No Default.  The execution, delivery and
performance by Borrower of this Agreement and each Loan Document to which it
is or will become a party (i) has been duly authorized on behalf of Borrower
by all necessary corporate action; (ii) does not contravene any law, statute,
rule or regulation or any judgment, decree or order of any court or
governmental agency by which Borrower is bound, or Borrower's articles of
incorporation, bylaws, or any preference stock provisions; (iii) shall not
result in or constitute a default under any agreement, contract, indenture,
mortgage, deed of trust, security agreement or other instrument to which
Borrower is a party or by which Borrower or any of its property, including
any Collateral, is bound; and (iv) shall not result in the creation or
imposition of (or the obligation to create or impose) any lien, charge or
encumbrances upon any assets or property of Borrower or upon any Collateral.

          (c)  Validity.  When executed and delivered by the parties hereto
and thereto, this Agreement and the Loan Documents shall be valid and binding
obligations of Borrower, and shall be enforceable against Borrower in

Page 3


accordance with their terms, except as enforceability may be limited by
equitable principles or by applicable bankruptcy, insolvency, reorganization,
moratorium or similar laws affecting the enforcement of creditors' rights
generally.

          (d)  Financial Statements.  Borrower has delivered or otherwise
made available to Lender:  (i) an audited consolidated balance sheet of
Borrower and its Subsidiaries as of December 31, 2005, and the related
audited consolidated statements of operations, changes in stockholders'
equity and cash flows for the fiscal year then ended, including in each case
the notes thereto, and (ii) the unaudited consolidated balance sheets of
Borrower and its Subsidiaries as of May 31, August 31, and November 30, 2005,
and the related unaudited statements of operations and cash flows for the
three-, six- and nine-months, respectively, then ended, including in each
case the notes thereto.  Such financial statements (x) fairly present, in all
material respects, the consolidated financial condition of Borrower and its
Subsidiaries as of the dates thereof and the results of Borrower's and its
Subsidiaries' consolidated operations for the periods covered thereby and (y)
have been prepared in accordance with GAAP, consistently applied in the
various statements throughout the periods involved, except as otherwise
expressly stated therein, and show all known material liabilities of Borrower
and its Subsidiaries, including contingent liabilities, long term leases and
unusual commitments as of the dates thereof.  Since the date of the balance
sheet included in the most recent financial statements, there has been no
adverse material change in the consolidated financial condition of Borrower.
All other information submitted by Borrower in support of the application for
the Loan is true and correct in all material respects as of the date of this
Agreement, except to the extent that such information expressly relates to an
earlier date, and no material adverse change has occurred.

          (e)  Property and Assets.  Borrower has good and marketable title
to all of Borrower's properties reflected in its balance sheets and financial
statements (except such as have been disposed of in the ordinary course of
business since the date of such balance sheets or financial statements),
including without limitation the Collateral described on Exhibit "D," and
such properties are free and clear of all liens, charges and encumbrances,
except for liens for taxes and assessments not yet due and except such liens,
charges and encumbrances, if any, on properties acquired subsequent to such
balance sheets or financing statements and disclosed to Lender.  It is
acknowledged by Borrower that the only liens, encumbrances and charges
permitted under this Agreement with respect to the Collateral are the
Permitted Liens, as defined in Section 5(a).

          (f)  Coins.  All of the Collateral consisting of Coins, as
described in Exhibit D (the "Coins"), was recovered by the Borrower from the
coordinates described in the Judgment entered by the United States District
Court for the Middle District of Florida on March 24, 2004, in the case
styled Odyssey Marine Explorations, Inc. v. The Unidentified Shipwrecked
Vessel or Vessels, et al., Case No. 8:03-CV-1668-T-24TBM (the "Case").  The
coordinates described in the Case are not within any state or national
boundaries.  No persons other than Atlantic Mutual Insurance Company and the
United States Government have provided notice to Borrower of any claims to

Page 4


any interest in or to the Coins.  Borrower has not assigned, conveyed or
otherwise transferred any of its rights to the Collateral to any Person,
except pursuant to this Agreement and the Collateral Control Agreement.

          (g)  Loss.  No substantial loss, damage, destruction or taking of
any of the real or personal property of Borrower or of the real or personal
property leased by Borrower has occurred which has not been fully restored or
replaced or which is not fully covered by insurance, less applicable
deductibles, and neither such property nor the business of Borrower has been
adversely affected in any substantial way as the result of any theft,
accident, strike, lockout, embargo, riot, war, or act of God, or the public
enemy.

          (h)  Litigation.  There are no investigations, actions, suits, or
proceedings by any federal, state or local government body, agency or
authority, or by any person, pending, or to the knowledge of Borrower,
threatened against Borrower or its Subsidiaries, or other proceedings to
which Borrower or its Subsidiaries are a party (including administrative or
arbitration proceedings), (i) which involve the possibility of any judgment
or liability not fully covered by insurance or by adequate reserves
established by Borrower, (ii) which may result in any material adverse change
in the business or condition, financial or otherwise, of Borrower, or in any
right, interest or title Borrower has in the Collateral, (iii) which involves
any claim of title to the Collateral, or (iv) which, to the knowledge of
Borrower, seek to restrain, enjoin, prohibit or obtain damages or other
relief with respect to the Borrower's conduct of its Business or the
transaction contemplated by this Agreement, including, but not limited to,
the denial of any necessary permit, license or certificate.

          (i)  Contracts; No Defaults.  Borrower is not a party to any
contract, agreement, lease or other instrument which would materially and
adversely affect the Collateral, Borrower's property, the Business,
operations or financial condition or Borrower's ability to perform its
obligations under this Agreement or any other Loan Document.  Borrower is not
in default under any contract, agreement, lease or other instrument to which
is a party and which is material to its property, the Business, prospects,
operations or financial condition.  No event of default or occurrence that,
with the giving of notice, the passage of time, or both, would constitute an
event of default thereunder has occurred and is continuing.

          (j)  Governmental Approvals.  Borrower has complied in all material
respects with all applicable laws and requirements of governmental
authorities including those governing Borrower's conduct of its Business.  No
authorization or approval or other action by, and no notice to or filing
with, any federal, state or local government body, agency or authority is
required for the due execution, delivery and performance by Borrower of this
Agreement or any other Loan Document.

          (k)  Subsidiaries.  Borrower has no subsidiaries (including
subsidiaries of Borrower and/or one or more subsidiaries) except Odyssey
Marine, Inc., a Florida corporation ("Marine"), OVH, Inc., a Nevada
corporation ("OVH"), Odyssey Marine Services, Inc., a Nevada corporation
("Marine Services"), Odyssey Retriever, Inc., a Nevada corporation
("Retriever"), and Odyssey Marine Entertainment, Inc., a Nevada corporation

Page 5


("Odyssey Entertainment", and together with Marine, OVH, Marine Services, and
Retriever, collectively the "Subsidiaries").

          (l)  Securities Laws.  No proceeds of the Loan will be used to
acquire any security in any transaction which is subject to Sections 13 and
14 of the Securities Exchange Act of 1934, as amended.  Borrower is not an
"investment company" or a company "controlled" by an "investment company"
(within the meaning of the Investment Company Act of 1940, as amended).

          (m)  Margin Regulations.  Borrower is not engaged in the business
of extending credit for the purpose of purchasing or carrying margin stock
(within the meaning of Regulation U issued by the Board of Governors of the
Federal Reserve System).  No proceeds of the Loan will be used to purchase or
carry any such margin stock or to extend credit to others for the purpose of
purchasing or carrying any such margin stock.

          (n)  Taxes.  Borrower has filed all federal, state, local and
foreign income tax returns, which to its knowledge, Borrower is required to
file, and has paid all taxes as shown on said returns and all assessments
received by Borrower to the extent that such taxes have become due.

          (o)  ERISA.

               (i)  All pension or welfare benefit plans within the
respective meanings of Section 3(2) and 3(1) of ERISA other than
multiemployer plans (within the meaning of Section 3(37) of ERISA), to which
Borrower is a party or to which Borrower makes any employer contributions
with respect to employees, are set forth on Exhibit "E" which is attached
hereto and made a part hereof.  With regard to the current or prior plan
years of each plan referred to in Exhibit "F," all contributions required to
meet the employer contribution obligations of Borrower under Section 412 of
the Code, Part 3 of Title I(B) of ERISA, the terms of the plan itself, or any
applicable collective bargaining agreement, with respect to the elapsed
portion of the current and previous plan years, have been duly made, and such
plan and its related trust have not incurred any accumulated funding
deficiency (within the meaning of Section 412(a) of the Code and Section 302
of ERISA) since the effective date of ERISA.

               (ii)  Borrower is not a party to any multiemployer plans
(within the meaning of Section 3(37) of ERISA).  In addition, Borrower has
not incurred any withdrawal liability under Title IV of ERISA (as amended by
the Multiemployer Pension Plan Amendments Act of 1980) with respect to any
multiemployer plan.

               (iii)  Neither Borrower nor any Subsidiary or affiliate of
Borrower has engaged in any "prohibited transactions" within the meaning of
Section 4975 of the Code or Section 406 of ERISA, which could subject
Borrower or such subsidiary or affiliate, or any other party, to the tax or
penalty on prohibited transactions imposed by Section 4975 of the Code.  The
execution, delivery and performance of this Agreement and the other
instruments, documents and agreements contemplated hereby, and the making of
the borrowing contemplated hereby by Borrower will not constitute such a

Page 6



"prohibited transaction" (assuming that the funds used by Lender to make the
Loan are disbursed from Lender's general funds and not from any separate
fiduciary or other account maintained by Lender).

               (iv)  No reportable event (as such term is defined in Title IV
of ERISA) has occurred with respect to, nor has there been terminated, any
plans subject to Title IV of ERISA and maintained for any employees of
Borrower or any member of any "controlled group of corporations" (as such
term is defined in Section 1563 of the Code) of which Borrower is a member.

               (v)  Borrower has paid all premiums due to the PBGC with
respect to each plan identified in Exhibit "F" and no premium, late payment
charge, premium penalty or interest thereon is due.  The PBGC has made no
demand on Borrower for payment of any liability, including interest, arising
under Title IV(D) of ERISA, and no lien exists in favor of the PBGC upon any
real or personal property or rights to such property belonging to.

          (p)  Environmental Matters.

               (i)  Borrower and all of its Subsidiaries, if any, are in
compliance in all material respects with all provisions of the Environmental
Laws, and with any rules, regulations, and administrative orders of any
governmental agency, and with any judgments, decrees or orders of any court
of competent jurisdiction with respect thereto.

               (ii)  None of Borrower or its Subsidiaries, if any, has
received from any governmental agency any written assessment, notice of
(primary or secondary) liability or notice of financial responsibility, or
any notice of any action, claim or proceeding to determine such liability or
responsibility, or the amount thereof, or to impose civil penalties with
respect to a site listed on any federal or state listing of sites containing
or believed to contain Hazardous Wastes, nor has any of Borrower or its
Subsidiaries, if any, received written notification from any governmental
agency that any hazardous substances (as defined under CERCLA) that it has
disposed of have been found in any site at which any governmental agency is
conducting an investigation or other proceeding under any Environmental Law.

               (iii)  To the knowledge of Borrower, no part of the real
property leased by Borrower in its business or any building, structure or
facility located thereon or improvement thereto contains or contained

part thereof, when the same shall become due and payable, except for such
items the validity of which is being contested in good faith by appropriate
proceedings; and all income, excess profits, excise, sales, gross receipts,
and other taxes, duties or imposts, whether of a like or different nature,

               (i)  grounds for the termination of any employee benefit plan
or other plan maintained for employees of Borrower and covered by Title IV;
or

               (ii)  the appointment of a trustee by the appropriate United
States District Court to administer any such plan; or

               (iii)  the termination of any such plan within the meaning of
such Title IV other than a "standard termination" within the meaning of
Section 4041(b) of ERISA; or

               (iv)  the institution of proceedings by the PBGC to terminate
any such plan or to appoint a trustee to administer any such plan; or

               (v)  a material outstanding liability of Borrower which has
resulted from the prior occurrence of any of the events enumerated in clauses
(i) through (iv) above.

          (s)  Insecurity.  If any condition or situation occurs, which, in
the sole determination of Lender, constitutes a danger or impairment to the
security and/or repayment of the Loan, and such condition or situation is not
remedied within thirty (30) days after written notice to Borrower to remedy
such condition or situation.

     9.   Remedies for Default.

          (a)  Termination of Advances.  Upon the occurrence of any Event of
Default or Default that, with the giving of notice, passage of time, or both,
shall constitute an Event of Default, Lender may, without notice, terminate
this facility with respect to further Advances under the Revolving Credit
Loan, in which event Lender shall have no further obligation to make Advances
as long as said Event of Default or Default shall continue.

          (b)  Acceleration and Setoff.  Upon the occurrence of any Event of
Default, Lender may, by written notice, declare the entire principal and all
interest on the Loan and all other indebtedness of Borrower to Lender,
whether Borrower's liability for payment thereof is primary or secondary,
direct or indirect, sole, joint, several, or joint and several, or whether
the indebtedness is matured or unmatured, due or to become due, fixed,
absolute or contingent, to be immediately due and payable and the Loan and
all such indebtedness thereupon shall be and become immediately due and

Page 18


payable, and Lender may proceed to collect the same by foreclosure, at law,
or as otherwise provided in the instruments, documents and/or agreements
signed by Borrower; provided, however, that in the event that the Loan or any
other such indebtedness is payable on demand, Borrower expressly waives the
foregoing requirement for written notice.  In addition, without limiting any
other right of Lender, whenever Lender has the right to declare any
indebtedness to be immediately due and payable (whether or not it has so
declared), Lender may set off against the indebtedness without notice any
amounts then owed to Borrower by Lender in any capacity, whether due or not
due, including without limitation deposits, stocks, bonds and other
securities and other assets held in any custodial accounts, and Lender shall
be deemed to have exercised its right to set off immediately at the time its
right to such election accrues.

          (c)  Cumulative Remedies.  All rights, remedies or recourses of
Lender under this Agreement, the Note or any other Loan Documents, under the
Uniform Commercial Code or other law, in equity or otherwise, are cumulative,
and exercisable concurrently, and may be pursued singularly, successively or
together and may be exercised as often as occasion therefor shall arise.  No
act of commission or omission by Lender, including, but not limited to, any
failure to exercise, or any delay, forbearance or indulgence in the exercise
of, any right, remedy or recourse  hereunder or any other Loan Document shall
be deemed a waiver, release or modification of that or any other right,
remedy or recourse, and no single or partial exercise of any right, remedy or
recourse shall preclude Lender from any other or future exercise of the
right, remedy or recourse or the exercise of any other right, remedy or
recourse.  No waiver or release of any such rights, remedies and recourses
shall be effective against Lender unless in writing and manually signed by an
authorized officer on Lender's behalf, and then only to the extent recited
therein.  A waiver, release or modification with reference to any one event
shall not be construed as continuing or constituting a course of dealing, nor
shall it be construed as a bar to, or as a waiver, release or modification
of, any subsequent right, remedy or recourse as to a subsequent event.

$3,000,000.00 Maximum                                        Tampa, Florida
                                                             March 29, 2006

     FOR VALUE RECEIVED the undersigned, ODYSSEY MARINE EXPLORATION, INC., a
Nevada corporation ("Maker"), promises to pay to the order of MERCANTILE BANK
and its successors or assigns, together with any other holder hereof
("Holder"), at 2307 West Kennedy Boulevard, Tampa, FL 33609, or such other
place as Holder may from time to time designate in writing, the aggregate
unpaid principal amount of all advances made by Holder to Maker, which amount
in no event shall exceed the sum of THREE MILLION AND 00/100 DOLLARS
($3,000,000.00), plus accrued interest, to be paid in lawful money of the
United States of America, as follows:

     1)   This Note shall bear interest at the rate equal to the "LIBOR 30
Day Index Rate" plus two hundred sixty-five basis points (2.65%) (the "LIBOR
Spread") per annum on the outstanding principal balance, but in no event
shall the interest rate be greater than the Maximum Rate (as defined below).
"LIBOR 30-Day Index Rate" means the rate of interest per annum equal to the
London Interbank Offered Rate ("LIBOR") for thirty (30) day U.S. dollar
deposits as published in the "Money Rates" column of the local edition of The
Wall Street Journal.  If such 30-Day Index Rate is no longer available,
Lender shall choose a new 30-Day Index Rate based on comparable information,
and such selection by Lender of a comparable rate shall be dispositive of the
issue as to the appropriate rate.  If more than one rate is quoted, Lender
shall use the arithmetic average of such rates.  This rate will be effective
on and from the date of disbursement of the Loan proceeds of this Note
through the last day of the current month based on the most recent
information available on the date of this Note.  On the first day of the next
month, the interest rate shall be readjusted to the current LIBOR 30-Day
Index Rate plus the LIBOR Spread based on the most recent rate information
available on the date that the interest rate is adjusted and such rate shall
be effective for the next thirty (30) day period.  The rate shall be adjusted
every thirty (30) days thereafter at the current LIBOR 30-Day Index Rate plus
the LIBOR Spread based on the most recent rate information available on the
date that the interest rate is adjusted.  If The Wall Street Journal is no
longer published or if The Wall Street Journal no longer publishes such rate,
then Lender shall select another publication that publishes such rate and
this new publication shall be substituted for The Wall Street Journal.

     2)   Advances and payments:

          (a)  All or part of the principal amount evidenced by this Note may
be borrowed (and to the extent any principal amount advanced is repaid by
Maker, such sum may be borrowed again) prior to the Maturity Date (as defined
below), but only in accordance with the terms of the Revolving Credit
Agreement (as defined below) and only if Maker is not in default hereunder or
under any Loan Documents (as defined below).  At no time, however, shall the
principal balance hereunder exceed THREE MILLION AND 00/100 DOLLARS
($3,000,000.00).

Page 1


          (b)  Payments of accrued interest only shall be due and payable
commencing on May 1, 2006, and continuing on the same day of every month.

          (c)  Maker shall have no obligation to repay the outstanding
principal balance prior to the Maturity Date, except for mandatory payments
of amounts owing hereunder in accordance with the terms of the Revolving
Credit Agreement or unless acceleration is made by Holder pursuant to the
provisions of this Note.

     The remaining outstanding principal indebtedness, together with all
accrued and unpaid interest thereon, shall be due and payable on April 21,
2008 (the "Maturity Date"), unless acceleration is made by Holder pursuant to
the provisions hereof.

     Interest on this Note shall be computed on the basis of a 365 day or 366
day year as the case may be for the actual number of days outstanding.

     Except as set forth in Section 1(d) of the Revolving Credit Agreement,
any payment or prepayment hereunder shall be applied first to unpaid costs of
collection and late charges, if any, then to accrued and unpaid interest and
the balance, if any, to installments of principal, in the inverse order of
their maturity.

     After maturity or acceleration, this Note shall bear interest at the
Default Interest Rate (as defined below) until paid in full.

     The actual amount due and owing from time to time hereunder shall be
evidenced by Holder's records of receipts and disbursements, which records
(absent manifest error) shall be conclusive evidence of such amount.

     This Note is executed pursuant to the terms and conditions of that
certain Amended and Restated Revolving Credit Agreement of even date herewith
between Maker, as Borrower, and Holder, as Lender (the "Revolving Credit
Agreement"), and is secured by, inter alia, an Amended and Restated Security
Agreement of even date herewith.  The foregoing and all other agreements,
instruments and documents delivered in connection therewith and herewith are
collectively referred to as the "Loan Documents."

     This Note has been executed and delivered in, and is to be governed by
and construed under the laws of, the State of Florida, as amended, except as
modified by the laws and regulations of the United States of America.

     Maker shall have no obligation to pay interest or payments in the nature
of interest in excess of the maximum rate of interest allowed to be
contracted for by law, as changed from time to time, applicable to this Note
(the "Maximum Rate").  Any interest in excess of the Maximum Rate paid by
Maker ("excess sum") shall be credited as a payment of principal, or, if
Maker so requests in writing, returned to Maker, or, if the indebtedness and
other obligations evidenced by this Note have been paid in full, returned to
Maker together with interest at the same rate as was paid by Maker during
such period.  Any excess sum credited to principal shall be credited as of
the date paid to Holder.  The Maximum Rate varies from time to time and from
time to time there may be no specific maximum rate.  Holder may, without such
action constituting a breach of any obligations to Maker, seek judicial

Page 2


determination of the applicable rate of interest, and its obligation to pay
or credit any proposed excess sum to Maker.


     The "Default Interest Rate" and, in the event no specific maximum rate
is applicable, the Maximum Rate shall be twenty five percent (25%) per annum
if the face amount of this Note is greater than $500,000.00; otherwise, it
shall be eighteen percent (18%) per annum.

     Holder shall have the right to declare the total unpaid balance hereof
to be immediately due and payable in advance of the Maturity Date upon the
failure of Maker to pay when due any payment of principal or interest or
other amount due hereunder; or upon the occurrence of an event of default
pursuant to any other Loan Documents now or hereafter evidencing, securing
payment of this Note or if Maker shall become insolvent or declare a
voluntary or involuntary petition of bankruptcy.  Exercise of this right
shall be without notice to Maker or to any other person liable for payment
hereof, notice of such exercise being hereby expressly waived.

     Without in any way altering the generality of this Note, upon the
occurrence of any event of default or upon an occurrence that, with the
giving of notice, or passage of time, or both, will constitute such an event
of default hereunder or under any other Loan Documents now or hereafter
evidencing, securing or guarantying payment of this Note, Holder shall have
no further obligation under this Note or any Loan Document to disburse
additional funds to Maker.

     Any payment hereunder not paid when due (at maturity, upon acceleration
or otherwise) shall bear interest at the Default Interest Rate from the due
date until paid.

     Provided Holder has not accelerated this Note, Maker shall pay Holder a
late charge of five percent (5%) of any required payment which is not
received by Holder when said payment is due.  The parties agree that said
charge is a fair and reasonable charge for the late payment and shall not be
deemed a penalty.

     Time is of the essence hereunder.  In the event that this Note is
collected by law or through attorneys at law, or under advice therefrom,
Maker agrees to pay all reasonable costs of collection, including reasonable
attorneys' fees, whether or not suit is brought, and whether incurred in
connection with collection, trial, appeal, bankruptcy or other creditors'
proceedings or otherwise.

     Acceptance of partial payments or payments marked "payment in full" or
"in satisfaction" or words to similar effect shall not affect the duty of
Maker to pay all obligations due hereunder, and shall not affect the right of
Holder to pursue all remedies available to it under any Loan Documents.

     The remedies of Holder shall be cumulative and concurrent, and may be
pursued singularly, successively or together, at the sole discretion of
Holder, and may be exercised as often as occasion therefor shall arise.  No
action or omission of Holder, including specifically any failure to exercise
or forbearance in the exercise of any remedy, shall be deemed to be a waiver

Page 3


or release of the same, such waiver or release to be effected only through a
written document executed by Holder and then only to the extent specifically
recited therein.  A waiver or release with reference to any one event shall
not be construed as continuing or as constituting a course of dealing, nor
shall it be construed as a bar to, or as a waiver or release of, any
subsequent remedy as to a subsequent event.

     Maker hereby consents and submits to the jurisdiction of the courts of
the State of Florida, and, notwithstanding its place of residence or
organization or the place of execution of this Note, any litigation relating
hereto, whether arising in contract or tort, by statute or otherwise, shall
be brought in (and, if brought elsewhere, shall be transferred to) a State
court of competent jurisdiction in Hillsborough County, Florida.

     Any notice to be given or to be served upon any party hereto in
connection with this Note, whether required or otherwise, may be given in any
manner permitted under the Loan Documents.

     Whenever the context so requires, the neuter gender includes the
feminine and/or masculine, as the case may be, and the singular number
includes the plural, and the plural number includes the singular.

     Maker hereby expressly waives any valuation and appraisal, presentment,
demand for payment, notice of dishonor, protest, notice of nonpayment or
protest, all other forms of notice whatsoever, and diligence in collection.

     MAKER, BY EXECUTING THIS NOTE OR ANY OTHER DOCUMENT CREATING SUCH
LIABILITY, WAIVES ITS RIGHTS TO A TRIAL BY JURY IN ANY ACTION, WHETHER
ARISING IN CONTRACT OR TORT, BY STATUTE OR OTHERWISE, IN ANY WAY RELATED TO
THIS NOTE.  THIS PROVISION IS A MATERIAL INDUCEMENT FOR HOLDER'S EXTENDING
CREDIT TO MAKER AND NO WAIVER OR LIMITATION OF HOLDER'S RIGHTS UNDER THIS
PARAGRAPH SHALL BE EFFECTIVE UNLESS IN WRITING AND MANUALLY SIGNED ON
HOLDER'S BEHALF.

     Maker acknowledges that the above paragraph has been expressly bargained
for by Holder as part of the loan evidenced hereby and that, but for Maker's
agreement, Holder would not have extended the loan for the term and with the
interest rate provided herein.

     This Note amends and restates in its entirety that certain Revolving
Credit Note dated April 21, 2005 executed by Maker in favor of Holder.

     IN WITNESS WHEREOF, Maker has executed this Note on the day and year
first above written.

EXHIBIT 10.3

                     AMENDED AND RESTATED SECURITY AGREEMENT

     THIS AMENDED AND RESTATED SECURITY AGREEMENT (this "Agreement") is
entered into this 29th day of March, 2006 by and between ODYSSEY MARINE
EXPLORATION, INC., a Nevada corporation ("Debtor"), and MERCANTILE BANK
("Secured Party").

                           1.   SECURITY INTEREST

     To secure payment and performance of the Obligations (as defined below),
Debtor grants Secured Party a security interest in all of the property
described below in which Debtor has or acquires an interest, wherever
located, whether now owned or hereafter acquired, ("Collateral"):

          (a)  All of the silver coins recovered by Debtor from the shipwreck
known as "SS Republic" as specifically listed on Schedule 1 attached hereto,
together with additions (the "Coins");

          (b)  All accounts, contract rights, documents, chattel paper
(including electronic chattel paper), instruments, and general intangibles,
and all returned or repossessed goods arising from sales of the Coins (the
"Accounts");

          (c)  All proceeds of insurance policies insuring any of the Coins
against loss (whether or not the Secured Party is a loss payee or additional
insured thereof) and any indemnity, warranty or guaranty payable by reason of
loss or damage to or otherwise with respect to the Coins;

          (d)  All salvage rights of the Debtor with respect to its services
in recovering the Coins;

          (e)  All equipment, fixtures, and inventory (including all goods
held for sale, lease or demonstration or to be furnished under contracts of
service, goods leased to others, trade-ins and repossessions, raw materials,
work in process and materials or supplies used or consumed in Debtor's
business), including all spare and repair parts, special tools, equipment and
replacements for any of the foregoing, and any software embedded therein or
related thereto;

          (f)  All financial assets, investment property, securities (whether
certificated or uncertificated, and including investment company securities),
security entitlements, securities accounts, commodity contracts, and
commodity accounts, including all substitutions and additions thereto, and
all dividends, distributions and sums distributable or payable from, upon or
in respect of such property;

          (g)  All commercial tort claims;

          (h)  All deposit accounts of Debtor maintained by Secured Party;

          (i)  All letter-of-credit rights; and


Page 1

          (j)  All supporting obligations that support the payment or
performance of any of the foregoing ("Supporting Obligations");

          (k)  All additions and accessions to, all proceeds, products,
offspring and profits of, and all rights and privileges incident to, any of
the foregoing.

          The term "Obligations" is used herein in its most comprehensive
sense and includes (without limitation) any and all present and future debts,
obligations and liabilities of Debtor to Secured Party pursuant to that
certain Amended and Restated Revolving Credit Agreement of even date herewith
(the "Loan Agreement") between Debtor and Secured Party, as the same may be
amended, renewed, modified or extended from time to time, and any and all
other debts, obligations, and liabilities of Debtor to Secured Party,
heretofore, now or hereafter made, incurred, or created, whether voluntary or
involuntary and however arising, whether due or not due, absolute or
contingent, liquidated or unliquidated, determined or undetermined, secured
or unsecured, whether Debtor is liable individually or jointly with others,
whether for principal, interest or other debts, obligations or liabilities,
and whether or not any or all such debts, obligations and liabilities are or
become barred by any statute of limitations or otherwise unenforceable,
including (without limitation) all obligations of Debtor under this
Agreement, all obligations with respect to overdrafts in deposit accounts,
letters of credit and bankers' acceptances, and interest rate swap, cap,
floor, collar, option and other derivative transactions, and including any of
the foregoing that arise after the filing of a petition by or against Debtor
under the United States Bankruptcy Code.

                         2.   DEBTOR'S WARRANTIES

     Debtor warrants to Secured Party that while any of the Obligations are
unpaid:

          (a)  Ownership.  Debtor is the owner of the Collateral free of all
encumbrances and security interests except Secured Party's security interest
and Permitted Liens, as defined in the Loan Agreement.

          (b)  Other Financing.  Unless waived by Secured Party in writing,
no financing statement (other than Secured Party's) is on file covering the
Collateral or its products or proceeds.

          (c)  Documents.  If Collateral is represented or covered by
documents of title, Debtor is the owner of the documents, free of all
encumbrances and security interests other than Secured Party's security
interest.

          (d)  Sale of Goods.  Each account and chattel paper constituting
Collateral arose from a bona fide sale of goods, which have been delivered or
shipped to the account debtor and for which Debtor has genuine invoices,
shipping documents or receipts.



Page 2


          (e)  Enforceability.  Each account, contract right and chattel
paper constituting Collateral is genuine and (except as disclosed to Secured
Party in writing) enforceable against the account debtor according to its
terms.  It and the transaction out of which it arose comply with all
applicable laws and regulations.  The amount represented by Debtor to Secured
Party as owing by each account debtor is the amount actually owing and is not
subject to setoff, credit, allowance or adjustment, except discount for
prompt payment, nor (except as disclosed to Secured Party in writing) has any
account debtor returned the goods or disputed its liability.  There has been
no default as of the date of this Agreement according to the terms of any
Accounts or Supporting Obligation and no step has been taken to foreclose the
security interest it evidences or otherwise enforce its payment.  As of the
date of this Agreement Debtor has no notice or knowledge of anything which
might impair the credit standing of any account debtor.

          (f)  Authority to Contract.  The execution and delivery of this
Agreement and any instruments evidencing Obligations will not violate or
constitute a breach of Debtor's articles of incorporation or bylaws or any
agreement or restriction to which Debtor is a party or is subject.

          (g)  Accuracy of Information.  All information, certificates or
statements given to Secured Party pursuant to this Agreement shall be true
and complete in all material respects when given, except to the extent that
such information, certificate or statement is expressly given as of an
earlier date.

          (h)  Form of Organization; Names and Addresses.  Debtor is a
corporation organized under the laws of the State of Nevada.  The name of
Debtor set forth in this Agreement is the correct and exact name of Debtor as
it appears in the offices of the Nevada Secretary of State.  Debtor does not
do business under any other name. The address appearing below Debtor's
signature is Debtor's chief executive office.  Debtor shall advise Secured
Party in writing at least thirty (30) days before any change of name,
identity, form of organization, state of organization, or chief executive
office.  The address where the Coins will be kept is set forth in Schedule 2.
No Coins will be kept at any other location without the prior written consent
of Secured Party, but the parties intend that the Coins, wherever located,
are covered by this Agreement.

          (i)  Environmental Laws.  (i) To the knowledge of Debtor, no
substances or materials have been, are or will be stored, deposited, treated,
recycled or disposed of on, under or at any real estate now or at any time
owned or occupied by Debtor ("Property") which substances or materials, if
known to be present on, at or under the Property, would require cleanup,
removal or some other remedial action under any federal, state or local laws,
regulations, ordinances, codes or rules relating to the discharge of air
pollutants, water pollutants, or process wastewater or otherwise relating to
hazardous or toxic substances or materials ("Environmental Laws"), (ii) To
the knowledge of Debtor, there are no conditions existing currently or likely
to exist during the term of this Agreement which would subject Debtor to
damages, penalties, injunctive relief or cleanup costs under Environmental
Laws, and (iii) Debtor is not subject to any judgment, decree, order or
citation relating to or arising out of Environmental Laws.


Page 3

                         3.   SALE AND COLLECTIONS

          (a)  Proceeds of Collateral.  So long as no default exists under
any of the Obligations or this Agreement, Debtor may sell the Coins and other
inventory in the ordinary course of Debtor's business for cash or on terms
approved by Secured Party (which approval shall not be unreasonably withheld,
conditioned or delayed).  So long as no default exists under any of the
Obligations or this Agreement, Debtor may sell the Coins in the ordinary
course of Debtor's business for cash or on terms approved by Secured Party
(which approval shall not be unreasonably withheld, conditioned or delayed),
at sales prices not less than the full appraised values as set forth on
Schedule 1.  The aggregate sales proceeds of all Coins shall be applied to
reduce on a dollar-for-dollar basis the amount of the Commitment (as defined
in the Loan Agreement), which Commitment comprises a portion of the
Obligations secured hereby, unless Debtor provides to Secured Party within
five (5) days after the closing of such sale substitution Coin(s), acceptable
to Secured Party, which have an appraised value equal to or greater than the
Coins which were sold.  All sales of Coins made in accordance with all of the
above terms and conditions shall be consummated free from any security
interest of Secured Party in accordance with the Florida Uniform Commercial
Code.

          (b)  Verification and Notification.  Secured Party may verify
accounts, chattel paper and contract rights in any manner, and Debtor shall
assist Secured Party in so doing.  Secured Party may at any time and Debtor
shall, upon request of Secured Party, notify the account debtors to make
payment directly to Secured Party and Secured Party may enforce collection
of, settle, compromise, extend or renew the indebtedness of such account
debtors.  Until account debtors are otherwise notified, Debtor, as agent of
Secured Party, shall make collections on the Collateral.

                          4.   DEBTOR'S COVENANTS

     Debtor agrees:

          (a)  Maintenance of Collateral.  Debtor shall:  maintain the
Collateral in salable condition and not permit its value to be materially
impaired; keep it free from all liens, encumbrances and security interests
(other than Secured Party's security interest and Permitted Liens (as defined
in the Loan Agreement)); defend it against all claims and legal proceedings
by persons other than Secured Party; pay and discharge when due all taxes,
license fees, levies and other charges upon it, other than for amounts
contested in good faith by appropriate proceedings; not sell, lease, license
or otherwise dispose of it or permit it to become a fixture or an accession
to other goods, except for sales of Coins authorized as provided in this
Agreement; not permit it to be used in violation of any applicable law,
regulation or policy of insurance; and, as to Collateral consisting of
instruments and chattel paper, preserve rights in it against prior parties.
Loss of or damage to the Collateral shall not release Debtor from any of the
Obligations.

          (b)  Insurance.  Unless otherwise agreed in writing by Secured
Party, Debtor shall keep the Collateral and Secured Party's interest in it
insured under policies with such provisions, for such amounts and by such
insurers as shall satisfy the requirements of the Loan Agreement.  Debtor

Page 4


assigns (and directs any insurer to pay) to Secured Party the proceeds of all
such insurance and any premium refund, and authorizes Secured Party to
endorse in the name of Debtor any instrument for such proceeds or refunds
and, at the option of Secured Party, to apply such proceeds and refunds to
any unpaid balance of the Obligations whether or not due, and/or to
restoration of the Collateral, returning any excess to Debtor.  Secured Party
is authorized, in the name of Debtor or otherwise, to make, adjust, settle
claims under and/or cancel any insurance on the Collateral.

          (c)  Maintenance of Security Interest.  Where Collateral is in the
possession of a third party, Debtor will join with Secured Party in notifying
the third party of Secured Party's security interest and obtaining an
acknowledgement from the third party that it is holding the Collateral for
the benefit of Secured Party.  Debtor will cooperate with Secured Party in
obtaining a Collateral Control Agreement in form and substance satisfactory
to Secured Party with respect to Collateral in the custody of any third
party.

          Debtor shall pay all expenses and, upon request, execute and
deliver any further documents and take any further actions reasonably deemed
advisable by Secured Party to preserve the Collateral or to establish,
determine priority of, perfect, continue perfected, terminate and/or enforce
Secured Party's interest in it or rights under this Agreement.

          (d)  Collateral Records and Statements.  Debtor shall keep accurate
and complete records respecting the Collateral in such form as Secured Party
shall reasonably request.  At such times as Secured Party may require, Debtor
shall furnish to Secured Party a statement certified by Debtor and in such
form and containing such information as may be prescribed by Secured Party,
showing the current status and value of the Collateral.

          (e)  Inspection of Collateral.  At reasonable times and in a manner
that will not unreasonably interfere with normal business operations, Secured
Party may examine the Collateral and Debtor's records pertaining to it,
wherever located, and make copies of records.  Debtor shall assist Secured
Party in so doing.

          (f)  Chattel Paper.  Chattel Paper constituting Collateral shall be
on forms approved by Secured Party.  Debtor shall promptly mark all such
chattel paper, and all copies, to indicate conspicuously the Secured Party's
interest and, upon request, deliver them to Secured Party.

          (g)  Modifications.  Without the prior written consent of Secured
Party (which consent will not be unreasonably withheld, conditioned or
delayed), Debtor shall not alter, modify, extend, renew or cancel any
Collateral.

          (h)  Returns and Repossessions.  Debtor shall promptly notify
Secured Party of the return to or repossession by Debtor of any Collateral
and Debtor shall hold and dispose of them only as Secured Party directs.


Page 5


          (i)  Taxes and Other Charges.  Debtor shall pay and discharge all
lawful taxes, assessments and governmental charges upon Debtor or against its
properties prior to the date on which penalties attach, unless and to the
extent only that such taxes, assessments and charges are contested in good
faith and by appropriate proceedings by Debtor.

                         5.   RIGHTS OF SECURED PARTY

          (a)  Authority to Perform for Debtor.  If Debtor fails to act as
required by this Agreement or the Obligations, Secured Party is authorized,
in Debtor's name or otherwise, to take any such action including, without
limitation, signing Debtor's name or paying any amount so required, and the
cost shall be one of the Obligations secured hereby and shall be payable by
Debtor upon demand with interest from the date of payment by Secured Party at
the highest rate then payable on the Obligations.

          (b)  Charging Debtor's Credit Balance.  Without limiting the
generality of Section 1 above, Debtor grants Secured Party, as security for
the Obligations, a security interest and lien in any credit balance and other
money now or hereafter owed Debtor by Secured Party, including deposit
accounts and certificates of deposit, and, in addition, agrees that Secured
Party may, without prior notice or demand, charge against any such credit
balance or other money any amount owing upon the Obligations, whether due or
not.

          (c)  Power of Attorney.  Debtor irrevocably appoints any officer of
Secured Party as Debtor's attorney, with power (exercisable at any time after
default) to receive, open and dispose of all mail addressed to Debtor; to
notify the Post Office authorities to change the address for delivery of all
mail addressed to Debtor to such address as Secured Party may designate; and
to endorse the name of Debtor upon any instruments which may come into
Secured Party's possession.

          The power of attorney created by this section 5(c) is coupled with
an interest and may not be revoked by Debtor. All acts of such attorney are
ratified and approved.  Such attorney is not liable for any act or omission
or for any error of judgment or mistake of fact or law taken without willful
misconduct.

          (d)  Nonliability of Secured Party.  Secured Party has no duty to
protect, insure, collect or realize upon the Collateral or preserve rights in
it against prior parties.  Debtor releases Secured Party from any liability
for any act or omission relating to the Obligations, the Collateral or this
Agreement, except Secured Party's willful misconduct.

          (e)  Financing Statements.  Debtor authorizes Secured Party to
prepare and file financing statements describing the Collateral in such
jurisdictions as Secured Party deems appropriate.

          (f)  No Waiver.  No delay on the part of the Secured Party in
exercising any right, power or privilege hereunder shall operate as a waiver
thereof, nor shall any single or partial exercise of any right, power or
privilege hereunder preclude other or further exercise thereof or the
exercise of any other right, power or privilege.  The rights and remedies

Page 6



herein specified are cumulative and not exclusive of any rights or remedies
which the Secured Party would otherwise have.

                                 6.   DEFAULT

     Upon the occurrence of any Event of Default, as defined in Article 8 of
the Loan Agreement or any other default under any instrument, document or
agreement evidencing or governing any of the Obligations, all of the
Obligations shall, at the option of Secured Party and without notice or
demand, become immediately payable; and Secured Party shall have all rights
and remedies for default provided by the Uniform Commercial Code, as well as
any other applicable law and the Obligations.  With respect to such rights
and remedies:

          (a)  Repossession.  To the extent permitted by applicable law,
Secured Party may enter into premises where any Collateral may be located,
and may take possession of Collateral, all without notice or hearing.

          (b)  Assembling Collateral.  Secured Party may require Debtor to
assemble the Collateral and to make it available to Secured Party at any
convenient place designated by Secured Party.  It is agreed that Secured
Party will not have an adequate remedy at law if this obligation is breached,
and accordingly that Debtor's obligation to assemble Collateral shall be
specifically enforceable.

          (c)  Notice of Disposition.  Written notice, when required by law,
sent to any address of Debtor in this Agreement at least 10 calendar days
(counting the day of sending) before the date of a proposed disposition of
the Collateral is reasonable notice.

          (d)  Disposition.  Secured Party may sell Collateral on credit (and
reduce the Obligations only when payment is actually received from the buyer)
at wholesale and with or without an agent or broker; and Secured Party may
but need not complete, process or repair any Collateral prior to disposition.

          (e)  Expenses and Application of Proceeds.  Debtor shall reimburse
Secured Party for any expense incurred by Secured Party in protecting or
enforcing its rights under this Agreement before and after judgment
including, without limitation, reasonable attorneys' fees and legal expenses
and all expenses of taking possession, holding, preparing for disposition and
disposing of the Collateral.  After deduction of such expenses, Secured Party
may apply the proceeds of disposition to the other Obligations in such order
and amounts as it elects, subject only to section 3(a) above.

          (f)  Waiver.  Secured Party may permit Debtor to remedy any default
without waiving the default so remedied, and Secured Party may waive any
default without waiving any other subsequent or prior default by Debtor.

          (g)  No Obligation to Pursue Others.  Secured Party has no
obligation to attempt to satisfy the Obligations by collecting them from any
other person liable for them and Secured Party may release, modify or waive
any collateral provided by any other person to secure any of the Obligations,

all without affecting Secured Party's rights against Debtor.  Debtor waives
any right it may have to require Secured Party to pursue any third person for
any of the Obligations.

          (h)  Compliance with Other Laws.  Secured Party may comply with any
applicable state or federal law requirements in connection with a disposition
of the Collateral, and such compliance will not be considered adversely to
affect the commercial reasonableness of any such disposition.

          (i)  Warranties.  Secured Party may sell or otherwise dispose of
Collateral without giving any warranties as to the Collateral and may
specifically disclaim any warranties of title or the like, all without being
deemed to have impaired the commercial reasonableness of any disposition of
Collateral.

          (j)  Sales on Credit.  If Secured Party sells any of the Collateral
on credit, Debtor will be credited only with payments actually made by the
purchaser, received by Secured Party and applied to the indebtedness of the
purchaser.  In the event the purchaser fails to pay for the Collateral,
Secured Party may resell the Collateral and Debtor shall be credited with the
proceeds of such resale.

          (k)  No Marshalling.  Secured Party shall have no obligation to
marshal any assets for the benefit of Debtor or any third party.

                              7.   PERSONS BOUND

     This Agreement benefits Secured Party, its successors and assigns,
including every holder or owner of any of the Obligations, binds the
Debtor(s) and their respective heirs, personal representatives and
successors, and shall bind all persons who become bound as a Debtor to this

written consent of Secured Party.
