ARTICLE 2TERMS OF THE LOANS AND LETTERS OF CREDIT

Section 2.1. Commitment
To Extend Loans. Subject to the terms and conditions of this AGREEMENT and
the other CREDIT DOCUMENTS, each of the LENDERS severally agrees to extend a
loan or loans to the BORROWER as an obligor (each a LOAN and collectively,
the LOANS) from time to time until the MATURITY DATE, in aggregate principal
amounts outstanding at any one time which do not exceed the amount of such
LENDERS COMMITMENT AMOUNT; provided, however, that the aggregate
principal unpaid balances of all outstanding and unpaid LOANS (after giving
effect to any amount requested) plus the aggregate amount of L/C
OBLIGATIONS shall not exceed the MAXIMUM AGGREGATE LOAN AMOUNT (as decreased
from time to time in accordance with the terms of this AGREEMENT). The BORROWER
shall not request any advances of proceeds of the LOANS which would cause the
aggregate unpaid principal balances of the LOANS to exceed either of the
above-stated limitations. In the event that the aggregate unpaid principal
balances of the LOANS exceed the limitations provided for herein, the BORROWER
shall immediately make such payments to the ADMINISTRATIVE AGENT as will be
sufficient to reduce the aggregate unpaid principal balances of the LOANS to an
aggregate amount which will not be in excess of such limitations. Each LOAN
extended by a LENDER shall be in a principal amount equal to the LENDERS
COMMITMENT PERCENTAGE of the aggregate principal balance of the LOANS requested
on such occasion. Subject to the terms and conditions of this AGREEMENT and
the other CREDIT DOCUMENTS, the BORROWER may borrow, prepay, and reborrow the
LOANS in whole or in part until the MATURITY DATE.

Section 2.1.1.

repay the LOANS to each of the LENDERS shall be evidenced by the NOTES in the

no longer materially accurate or correct. The BORROWER acknowledges that each
request by the BORROWER for an advance of proceeds of the LOANS constitutes a
reaffirmation by the BORROWER of the continuing accuracy of such
representations and warranties, except to the extent to the contrary disclosed
to the ADMINISTRATIVE AGENT by written notice from the BORROWER.

LENDERS an unused commitment fee (COMMITMENT FEE) calculated by subtracting
the average daily disbursed aggregate principal balances of the LOANS and the
average aggregate face amount of issued and outstanding LETTERS OF CREDIT
during such FISCAL QUARTER (calculated on the basis of the actual number of
days elapsed in a year of 360 days) from the MAXIMUM AGGREGATE LOAN AMOUNT (as
such MAXIMUM AGGREGATE LOAN AMOUNT may be reduced from time to time in
accordance with the provisions of this AGREEMENT), and multiplying any positive

COMMITMENT FEES to be paid on February 2, 2004 for the period of

($5,000,000.00) or, if greater, an integral multiple of One Million Dollars
($1,000,000.00); and (b) no reduction shall be permitted if, after giving
effect thereto, and to any repayments of the LOANS made on the effective date
thereof, the aggregate principal balances of the LOANS then unpaid and
outstanding would exceed the MAXIMUM AGGREGATE LOAN AMOUNT then in effect.

Section 2.2. Interest Terms Applicable To The Loans. Interest shall
accrue upon the unpaid principal balances of the LOANS until the LOANS have
been repaid in full at the rate or rates described below in this Section 2.2.

Section 2.2.1. Adjusted Base Rate. Except as otherwise provided by the
terms of this AGREEMENT, the LOANS shall bear interest on the unpaid principal
balances at the fluctuating ADJUSTED BASE RATE. Absent a timely election by
the BORROWER in accordance with Section 2.2.2.b of this AGREEMENT, the unpaid
balances of the LOANS, including any balances of any LIBOR BORROWINGS for which
the applicable INTEREST PERIOD has expired, shall be automatically deemed to
bear interest at the ADJUSTED BASE RATE. Changes in the interest rate shall be
made when and as changes in the BASE RATE occur. For each BASE RATE BORROWING,
all accrued and unpaid interest shall be payable monthly in arrears on the
first BUSINESS DAY of each succeeding calendar month, with the first of such
payments to be due on February 2, 2004. Each election by the BORROWER of a
BASE RATE BORROWING shall be in the MINIMUM BORROWING AMOUNT applicable to BASE
RATE BORROWINGS, or any multiple thereof.

Section 2.2.2. Adjusted LIBOR Rate Option. Subject to the terms of this
Section, interest may accrue at the election of the BORROWER for INTEREST
PERIODS selected by the BORROWER, at the ADJUSTED LIBOR RATE on portions of the
unpaid principal
balances of the LOANS. Any LIBOR BORROWING or election for a LIBOR
BORROWING pursuant to the provisions of this Section shall be subject to the
following terms and conditions:

a. Payments. For each of the LIBOR BORROWINGS, accrued interest shall be
paid to the ADMINISTRATIVE AGENT for the accounts of the LENDERS in arrears on
the first BUSINESS DAY of each month during each INTEREST PERIOD and on the
last day of each applicable INTEREST PERIOD.

b. Notice Of Election. By 10:00 a.m. Buffalo, New York time on that
BUSINESS DAY which occurs two (2) BUSINESS DAYS prior to the BUSINESS DAY on
which the BORROWER desires that an INTEREST PERIOD commence, the BORROWER shall
deliver a written election to the ADMINISTRATIVE AGENT specifying: (1) the
commencement date of and length of the relevant INTEREST PERIOD, and (2) the
dollar amount of that portion of the total aggregate principal amount of the
LOANS identified by the BORROWER, which are to bear interest at the ADJUSTED
LIBOR RATE, which amount shall not be less than the MINIMUM BORROWING AMOUNT
applicable to LIBOR BORROWINGS and with any increments to the MINIMUM BORROWING
AMOUNT to be in minimum multiples of Two Hundred Fifty Thousand Dollars
($250,000.00).

c. Effect Of Election. Interest shall accrue from and including the first
day of each INTEREST PERIOD selected by the BORROWER to (but not including) the
last day of such INTEREST PERIOD at the ADJUSTED LIBOR RATE determined as
applicable to such INTEREST PERIOD upon the amount of the unpaid principal
balances of the LOANS identified by the BORROWER in the BORROWERS written
election.





---



##### 



d. Interest Periods. There shall be no more than five (5) INTEREST
PERIODS outstanding at any one time. No INTEREST PERIOD may expire after the
MATURITY DATE.

e. Availability. If the REQUIRED LENDERS determine at any time that a
REGULATORY CHANGE or a change in market conditions has made it impractical for
the LENDERS to offer pricing based on the ADJUSTED LIBOR RATE, the
ADMINISTRATIVE AGENT may give notice of such determination to the BORROWER, and
all advances which are then accruing interest at an ADJUSTED LIBOR RATE shall,
on the last day(s) of the then applicable current INTEREST PERIOD(S)
automatically and without further notice, begin to accrue interest at the
ADJUSTED BASE RATE. Until such time as the REQUIRED LENDERS determine that a
REGULATORY CHANGE or a change in market conditions has again made it practical
for the LENDERS to offer pricing at the ADJUSTED LIBOR RATE, the LENDERS will
not be obligated to further offer pricing based upon the ADJUSTED LIBOR RATE,
and any notice from the BORROWER requesting such a rate option will be
ineffective.

f. Breakage Costs. The BORROWER agrees to compensate the LENDERS from time
to time, upon demand from any LENDER through the ADMINISTRATIVE AGENT, for all
losses, expenses, lost earnings, costs and liabilities (including, without
limitation, all interest paid to lenders of funds borrowed by the LENDERS to
carry LIBOR BORROWINGS) which any of the LENDERS sustains if: any repayment or
prepayment of any LIBOR BORROWINGS (including, without limitation, any payment
resulting from the acceleration of the LOANS in accordance with the terms of
this AGREEMENT or as a result of any mandatory prepayments required by the
terms of this AGREEMENT) or any conversion of a LIBOR BORROWING for any reason
occurs on a date which is not the last day of the applicable INTEREST PERIOD;
or any failure by the BORROWER to borrow a LIBOR BORROWING or convert a BASE
RATE BORROWING to a LIBOR BORROWING on the date for such borrowing or
conversion specified in the relevant notice of election given by the BORROWER
to the LENDERS in accordance with the terms of this AGREEMENT.

g. Termination Of Right To Elect LIBOR Borrowings. Notwithstanding
anything to the contrary set forth in this AGREEMENT, and without limiting any
other rights and remedies of the LENDERS, the REQUIRED LENDERS during any
continuing DEFAULT or EVENT OF DEFAULT may suspend the right of the BORROWER to
convert any BASE RATE BORROWING into a LIBOR BORROWING or to permit any LIBOR
BORROWING to be renewed as a LIBOR BORROWING, in which case all LOANS shall be
converted (on the last days of the respective INTEREST PERIODS therefor) or
continued, as the case may be, as BASE RATE BORROWINGS.

Section 2.2.3.Calculation Of Interest. Interest shall be calculated upon
LIBOR BORROWINGS on the basis of a 360 day per year factor applied to the
actual days on which there exists an unpaid balance of the LIBOR BORROWINGS.
Interest shall be calculated upon BASE RATE BORROWINGS on the basis of a 365 or
366 days per year factor applied to the actual days on which there exists an
unpaid balance of the BASE RATE BORROWINGS.

Section 2.2.4.Default Interest. The interest rates payable upon the
LOANS may be increased during any continuing EVENT OF DEFAULT upon the
authorization of the REQUIRED LENDERS to that rate equal to the ADJUSTED BASE
RATE plus two hundred (200) BASIS POINTS until the EVENT OF DEFAULT has been
cured to the satisfaction of the REQUIRED LENDERS or waived by the
ADMINISTRATIVE AGENT upon the authorization of the REQUIRED LENDERS.

Section 2.2.5. Maximum Rate Of Interest. Any provision contained in the
CREDIT DOCUMENTS to the contrary notwithstanding, the holders of the NOTES
shall not be entitled to receive or collect, nor shall the BORROWER be
obligated to pay, interest, fees, or charges thereunder in excess of the
maximum rate of interest permitted by any applicable LAW, and if any provision
of this AGREEMENT, the NOTES or any of the other CREDIT DOCUMENTS is construed
or held by any court of law or GOVERNMENTAL BODY having jurisdiction to permit
or require the charging, collection or payment of any amount of interest in
excess of that permitted by such LAWS, the provisions of this Section shall
control and shall override any contrary or inconsistent provision. The
intention of the parties is to at all times conform strictly with all
applicable usury requirements and other LAWS limiting the maximum rates





---



##### 



of interest which may be lawfully charged upon the LOANS. The interest to be paid
pursuant to the NOTES shall be held subject to reduction to the amount allowed
under said usury or other laws as now or hereafter construed by the courts
having jurisdiction, and any sums of money paid in excess of the interest rate
allowed by applicable law shall be applied in reduction of the principal amount
owing pursuant to the NOTES. The BORROWER acknowledges and irrevocably
stipulates for all purposes that it has been contemplated at all times by the
parties that the LAWS of the State of Maryland will govern the maximum rate of
interest that it is permissible for the LENDERS to charge the BORROWER.

Section 2.2.6. Late Payment Charges. Any payment of principal, interest
or fees due upon any of the LOANS which is received by the ADMINISTRATIVE AGENT
more than fifteen (15) calendar days after its due date shall incur a late
payment charge equal to five percent (5%) of the amount of the payment due.
All late payment charges shall be payable upon the demand of the ADMINISTRATIVE
AGENT. The existence of the right by the LENDERS to receive a late payment
charge shall not be deemed to constitute a grace period or provide any right to
the BORROWER to make a payment other than on such payments scheduled due date.

Section 2.3. Voluntary Prepayments. Any principal balances of the LOANS
accruing interest at the ADJUSTED LIBOR RATE may be prepaid in whole or in part
at any time without penalty or premium, provided that the LENDERS are
compensated for any breakage costs incurred by the LENDERS as a result of any
such repayment in accordance with the provisions of Section 2.2.2.f of this
AGREEMENT. Any principal balance of the LOANS bearing interest at the BASE
RATE may be prepaid in whole or in part at any time without penalty or premium.

Section 2.4. Mandatory Prepayments. The BORROWER shall have the
obligation to apply to the unpaid principal balances of the LOANS and all
accrued interest and fees all of the NET AVAILABLE PROCEEDS received by the
BORROWER from any PREPAYMENT DISPOSITIONS, CASUALTY EVENTS, or issuances of
INDEBTEDNESS for borrowed money other than proceeds from purchase money
INDEBTEDNESS which is otherwise permitted by the terms of this AGREEMENT. The
MAXIMUM AGGREGATE LOAN AMOUNT and the COMMITMENT AMOUNTS shall be permanently
reduced by the amount of each payment of the NET AVAILABLE PROCEEDS that is
applied to the unpaid principal balances of the LOANS. Notwithstanding the
foregoing, (A) an amount equal to such NET AVAILABLE PROCEEDS shall not be
required to be so applied to any of the OBLIGATIONS and to the reduction of the
MAXIMUM AGGREGATE LOAN AMOUNT and the COMMITMENT AMOUNTS so long as no DEFAULT
or EVENT OF DEFAULT is then continuing and such NET AVAILABLE PROCEEDS (i) do
not exceed Five Million Dollars ($5,000,000.00) when
aggregated with all other NET AVAILABLE PROCEEDS not applied to the
OBLIGATIONS and the permanent reduction of the MAXIMUM AGGREGATE LOAN AMOUNT
and the COMMITMENT AMOUNTS, and (ii) are used to purchase replacement assets,
in each case within 180 days following the date of receipt of such NET
AVAILABLE PROCEEDS, and (B) if all or any portion of such NET AVAILABLE
PROCEEDS not required to be so applied as provided above in this Section 2.4
are not so reinvested to purchase replacement assets within such 180-day period
(or such earlier date, if any, if the BORROWER determines not to reinvest the
NET AVAILABLE PROCEEDS as set forth above), an amount equal to such remaining
portion shall be applied on the last day of such period (or such earlier date,
as the case may be) as provided above in this Section 2.4 without regard to
this proviso.

Section 2.5. Letters Of Credit. Subject to the terms and conditions of
this AGREEMENT, the ADMINISTRATIVE AGENT, in reliance upon the agreements of
the LENDERS set forth in Section 2.5.3 of this AGREEMENT, agrees to issue
LETTERS OF CREDIT for the account of the BORROWER on any BUSINESS DAY from the
CLOSING DATE through but not including the MATURITY DATE in such form as may be
approved from time to time by the ADMINISTRATIVE AGENT provided: (a) no DEFAULT
or EVENT OF DEFAULT has occurred and is then continuing; (b) the aggregate
amount of L/C OBLIGATIONS (after giving effect to any requested issuance) shall
not exceed Five Million Dollars ($5,000,000.00); (c) the sum of the L/C
OBLIGATIONS (after giving effect to the requested issuance) plus the aggregate
unpaid principal balances of the LOANS shall not exceed the MAXIMUM AGGREGATE





---



##### 



LOAN AMOUNT (as decreased from time to time in accordance with the terms of
this AGREEMENT); (d) no LETTER OF CREDIT shall have a term greater than one (1)
year nor an expiration date later than the MATURITY DATE; and (e) the issuance
of any requested LETTER OF CREDIT shall not conflict with or cause the
ADMINISTRATIVE AGENT or any LENDER to exceed any limits imposed by any LAWS
applicable to the ADMINISTRATIVE AGENT or the LENDER.

Section 2.5.1 Procedures For Issuance Of Letters Of Credit. The BORROWER
may from time to time request that the ADMINISTRATIVE AGENT issue a LETTER OF
CREDIT by delivering to the ADMINISTRATIVE AGENT a completed letter of credit
application in the standard form then being used by the ADMINISTRATIVE AGENT.
To the extent that any provisions of the ADMINISTRATIVE AGENTS standard form
letter of credit application conflict with the provisions of this AGREEMENT,
the provisions of this AGREEMENT shall control. Upon receipt of the BORROWERS
application, the ADMINISTRATIVE AGENT shall process such application and issue
the LETTER OF CREDIT requested thereby provided, however, that the
ADMINISTRATIVE AGENT shall not be required to issue any LETTER OF CREDIT
earlier than three (3) BUSINESS DAYS after the receipt by the ADMINISTRATIVE
AGENT of the application and of all certificates, documents, and other papers
and information required by the ADMINISTRATIVE AGENT which relates thereto. The
ADMINISTRATIVE AGENT shall promptly furnish a copy of each LETTER OF CREDIT to
the BORROWER and to each of the LENDERS.

Section 2.5.2. Commissions And Charges. The BORROWER shall pay to the
ADMINISTRATIVE AGENT for the account of the LENDERS a per annum fee with
respect to each LETTER OF CREDIT in an amount equal to that sum obtained by
multiplying the face amount of each LETTER OF CREDIT by the APPLICABLE
PERCENTAGE for LETTERS OF CREDIT in effect on the date of the issuance of the
LETTER OF CREDIT, which fee shall be payable on the date of issuance of each
LETTER OF CREDIT. The BORROWER shall further pay or reimburse the
ADMINISTRATIVE AGENT for such normal and customary costs and expenses as are
incurred or charged by the ADMINISTRATIVE AGENT in issuing, effecting payment
under, amending, extending, renewing, or otherwise administering any LETTER OF
CREDIT.

Section 2.5.3. Agreement Of Lenders To Purchase Proportionate Share Of
Letters Of Credit. In order to induce the ADMINISTRATIVE AGENT to issue
LETTERS OF CREDIT for the account of the BORROWER in accordance with the terms
of this AGREEMENT, each LENDER unconditionally and irrevocably agrees to accept
and purchase and hereby accepts and purchases from the ADMINISTRATIVE AGENT, on
the terms and conditions hereinafter stated, for such LENDERS own account and
risk an undivided interest equal to such LENDERS COMMITMENT PERCENTAGE in the
ADMINISTRATIVE AGENTS obligations and rights under each LETTER OF CREDIT
issued hereunder and the amount of each draft paid by the ADMINISTRATIVE AGENT
thereunder. Each LENDER unconditionally and irrevocably agrees with the
ADMINISTRATIVE AGENT that, if a
draft is paid under any LETTER OF CREDIT for which the ADMINISTRATIVE
AGENT is not immediately reimbursed in full by the BORROWER in accordance with
the terms of this AGREEMENT, such LENDER shall pay to the ADMINISTRATIVE AGENT
upon demand by the ADMINISTRATIVE AGENT of an amount equal to such LENDERS
COMMITMENT PERCENTAGE of the amount of such draft, or any part thereof, which
is not so reimbursed.

Section 2.5.4. Reimbursement Obligations Of The Borrower. The BORROWER
unconditionally and irrevocably agrees to reimburse the ADMINISTRATIVE AGENT on
each date on which the ADMINISTRATIVE AGENT notifies the BORROWER of the date
and amount of a draft paid under any LETTER OF CREDIT for the amount of such
draft so paid and any taxes, charges, or other costs or expenses incurred by
the ADMINISTRATIVE AGENT in connection with such payment. If any draft under a
LETTER OF CREDIT is payable in a currency other than U.S. dollars, the BORROWER
shall reimburse the ADMINISTRATIVE AGENT for such draft by paying to the
ADMINISTRATIVE AGENT the equivalent in U.S. dollars of the amount required to
purchase the currency from the ADMINISTRATIVE AGENT at the ADMINISTRATIVE
AGENTS current selling rate of exchange in Buffalo, New York for cable
transfers to the place of payment in the currency and amount in which such
draft was drawn (or if there is no current selling rate of exchange generally
offered by the ADMINISTRATIVE AGENT for effecting such cable transfers, the
amount of U.S. dollars required to be paid shall be based on such rate





---



##### 



as the
ADMINISTRATIVE AGENT shall determine in good faith for such purpose). Interest
shall be payable on any and all amounts remaining unpaid by the BORROWER under
this Section from the date such amounts become payable (whether at stated
maturity, by acceleration, or otherwise) until payment in full at the BASE
RATE. Each drawing under any LETTER OF CREDIT shall be deemed to automatically
constitute a request by the BORROWER to the ADMINISTRATIVE AGENT for a BASE
RATE BORROWING under the LOANS in the amount of such drawing to be made on the
date on which the ADMINISTRATIVE AGENT notifies the BORROWER of the drawing,
and the proceeds of such BASE RATE BORROWING shall be applied automatically by
the LENDER to satisfy the BORROWERS reimbursement obligations set forth in
this Section.

Section 2.5.5. Borrowers Reimbursement Obligations Are Absolute. The
BORROWERS reimbursement obligations hereunder shall be absolute and
unconditional under any and all circumstances and irrespective of any set-off,
counterclaim or defense to payment which the BORROWER may have or has had
against the ADMINISTRATIVE AGENT, the LENDERS, or any beneficiary of a LETTER
OF CREDIT. The BORROWER agrees that neither the ADMINISTRATIVE AGENT nor any
of the LENDERS shall be responsible for, nor shall the BORROWERS duties and
obligations hereunder under the LOAN DOCUMENTS be affected by, among other
things, the form, validity, sufficiency, accuracy, genuineness or legal effect
of documents or of any endorsements thereon, even though such documents shall
in fact prove to be invalid, fraudulent or forged, or any dispute between or
among the BORROWER and any beneficiary of any LETTER OF CREDIT or any other
party to which such LETTER OF CREDIT may be transferred or any claims
whatsoever of the BORROWER against any beneficiary of such LETTER OF CREDIT or
any such transferee. Neither the ADMINISTRATIVE AGENT nor the LENDERS shall be
liable for any error, omission, interruption or delay in transmission, dispatch
or delivery of any message or advice, however transmitted, in connection with
any LETTER OF CREDIT. The BORROWER agrees that any action taken or omitted by
the ADMINISTRATIVE AGENT or the LENDERS under or in connection with any LETTER
OF CREDIT or the related drafts or documents shall be binding on the BORROWER
and shall not result in any liability of the ADMINISTRATIVE AGENT or the
LENDERS to the BORROWER, absent the gross negligence or wilful misconduct of
the ADMINISTRATIVE AGENT or the LENDERS.

Section 2.6. Pro Rata Treatment And Payments.

Section 2.6.1.Distribution Of Payments To Lenders. Except as otherwise
expressly provided to the contrary by the terms of this AGREEMENT, all payments
(including prepayments) to be made by the BORROWER hereunder, whether on
account of principal, interest, fees or otherwise shall be made without set-off
or counterclaim and shall be made prior to 12:00 Noon Buffalo, New York time on
the due date thereof to the ADMINISTRATIVE AGENT for the accounts of the
LENDERS at the ADMINISTRATIVE AGENTS offices in Buffalo, New York, in immediately
available U.S. Dollars. The ADMINISTRATIVE AGENT shall distribute such
payments to the LENDERS entitled to receive the same promptly upon receipt in
like funds as received.

Section 2.6.2. Funding Of Loans. The LENDERS agree that the
ADMINISTRATIVE AGENT may assume that each LENDER will fund its pro rataportion
of each borrowing requested by the BORROWER in accordance with the terms of
this AGREEMENT and that the ADMINISTRATIVE AGENT may, in reliance upon such
assumption, make available to the BORROWER a corresponding amount. If such
amount is not funded and made available to the ADMINISTRATIVE AGENT by the time

AUTHORITY, central bank, or comparable agency charged with the interpretation
or administration thereof, or any request or directive regarding capital
adequacy (whether or not having the force of law) of any such GOVERNMENTAL
AUTHORITY, central bank, or comparable agency after the date hereof has or
would have the effect of reducing the rate of return on the capital of such
LENDER or any corporation controlling such LENDER as a consequence of such
LENDERS obligations hereunder to a level below that which such LENDER or such
corporation could have achieved but for such adoption, change, request, or
directive (taking into consideration its policies with respect to capital

ARTICLE 8RIGHTS AND REMEDIES ON THE OCCURRENCEOF AN EVENT OF DEFAULT

Upon the occurrence of an EVENT OF DEFAULT, the ADMINISTRATIVE AGENT
shall, at the request of, or may with the consent of, the REQUIRED LENDERS,
take any or all of the following actions:

Section 8.1. Secured Parties Specific Rights And Remedies. In addition
to all other rights and remedies provided by LAWS and the CREDIT DOCUMENTS,
upon the occurrence of any EVENT OF DEFAULT, the ADMINISTRATIVE AGENT may with
the consent of the REQUIRED LENDERS and shall at the request of the REQUIRED
LENDERS: (a) accelerate and call immediately due and payable all or any part
of the OBLIGATIONS; (b) seek specific performance or injunctive relief to
enforce performance of the undertakings, duties, and agreements provided in the
CREDIT DOCUMENTS, whether or not a remedy at law exists or is adequate; and (c)
exercise any rights of a secured creditor under the Uniform Commercial Code, as
adopted and amended in Maryland or as otherwise applicable, including the right
to take possession of the COLLATERAL without the use of judicial process or
hearing of any kind and the right to require the BORROWER to assemble the
COLLATERAL at such place as the ADMINISTRATIVE AGENT may specify.

Section 8.2. Automatic Acceleration. Upon the occurrence of an EVENT OF
DEFAULT as described in Sections 7.9 or 7.10 of this AGREEMENT, the OBLIGATIONS
shall be automatically accelerated and due and payable without any notice,
demand or action of any type on the part of the SECURED PARTIES.

Section 8.3. Sale Of Collateral. In addition to any other remedy provided
herein, upon the occurrence of an EVENT OF DEFAULT, the ADMINISTRATIVE AGENT,
in a commercially reasonable fashion, may sell at public or private sale or
otherwise realize upon, in Baltimore, Maryland, or elsewhere, the whole or,
from time to time, any part of all COLLATERAL which is personal property, or
any interest which the BORROWER may have therein. Pending any such action, the
ADMINISTRATIVE AGENT may collect and liquidate the COLLATERAL. After deducting
from the proceeds of sale or other disposition of such COLLATERAL all expenses,
including all expenses for legal services, the ADMINISTRATIVE AGENT shall apply
such proceeds toward the satisfaction of the OBLIGATIONS. Any remainder of the
proceeds after satisfaction in full of the OBLIGATIONS shall be distributed as
required by applicable LAW. Notice of any sale or other disposition (other
than sales or other dispositions of COLLATERAL which is perishable or threatens
to decline speedily in value or of a type customarily sold on a recognized
market) shall be given to the BORROWER not less than ten (10) calendar days
before the time of any intended public sale or of the time after which any
intended private sale or other disposition of the COLLATERAL is to be made,
which the BORROWER hereby agrees would be commercially reasonable notice of
such sale or other disposition. The BORROWER agrees to assemble, or to cause
to be assembled, at the BORROWERS expense, the COLLATERAL at such place or
places as the ADMINISTRATIVE AGENT designates. At any such sale or other
disposition, the ADMINISTRATIVE AGENT may, to the extent permissible under
applicable law, purchase the whole or any part of the COLLATERAL, free from any
right of redemption on the part of the BORROWER, which right is hereby waived
and released to the extent lawfully permitted. Without limiting the generality
of any of the rights and remedies conferred upon the ADMINISTRATIVE AGENT under
this Section, the ADMINISTRATIVE AGENT may, to the full extent

##### 



permitted by
applicable law: (a) enter upon the premises of the BORROWER, exclude therefrom
the BORROWER or any PERSON connected therewith, and take immediate possession
of the COLLATERAL, either personally or by means of a receiver appointed by a
court of competent jurisdiction, using all necessary force to do so; (b) at the
ADMINISTRATIVE AGENTS option, use, operate, manage, and control the COLLATERAL
in any lawful manner; (c) collect and receive all income, revenue, earnings,
issues, and profits therefrom; and (d) maintain, alter or remove the
COLLATERAL.

Section 8.4. Letters Of Credit. Upon the request of the ADMINISTRATIVE
AGENT, during any continuing EVENT OF DEFAULT, the BORROWER shall immediately
deposit in a cash collateral account to be maintained by the ADMINISTRATIVE
AGENT for the benefit of the LENDERS, over which the ADMINISTRATIVE AGENT has
exclusive dominion, an amount equal to the aggregate then undrawn and unexpired
amount of all LETTERS OF CREDIT. Amounts held in such cash collateral account
shall be applied by the ADMINISTRATIVE AGENT to the payment of drafts drawn
under LETTERS OF CREDIT, and the unused portion thereof after all LETTERS OF
CREDIT shall have expired or been fully drawn upon shall be applied to repay
any remaining unpaid OBLIGATIONS. After all LETTERS OF CREDIT have expired or
have been fully drawn upon and all other OBLIGATIONS have been paid in full,
the balance, if any, in such cash collateral account shall be returned to the
BORROWER. In the event the BORROWER fails to deposit into the cash collateral
account an amount equal to the then undrawn and unexpired amount of all LETTERS
OF CREDIT, the ADMINISTRATIVE AGENT shall be authorized to deposit into such
cash collateral account proceeds from the liquidation of the COLLATERAL until
the balance in such account equals the aggregate then undrawn and unexpired
amount of all LETTERS OF CREDIT.

Section 8.5. Remedies Cumulative. The rights and remedies provided in
this AGREEMENT and in the other CREDIT DOCUMENTS or otherwise under applicable
LAWS shall be cumulative and the exercise of any particular right or remedy
shall not preclude the exercise of any other rights or remedies in addition to,
or as an alternative of, such right or remedy.

BORROWER), independent accountants and other experts selected by the
ADMINISTRATIVE AGENT. The ADMINISTRATIVE AGENT may deem and treat the payee of
any NOTE as the owner thereof for all purposes unless such NOTE shall have been
transferred in accordance with the applicable provisions of this AGREEMENT.
The ADMINISTRATIVE AGENT shall be fully justified in refusing to take any
action requested or suggested by a LENDER in connection with this AGREEMENT or
any of the other CREDIT DOCUMENTS or which otherwise relates to the BORROWER or
the COLLATERAL, unless the ADMINISTRATIVE AGENT shall first receive such advice
or concurrence of the REQUIRED LENDERS, and the ADMINISTRATIVE AGENT is

AGENT, deems advisable.

Section 9.7.Non-Reliance On The Administrative Agent And Other Lenders.
Each LENDER expressly acknowledges that neither the ADMINISTRATIVE AGENT nor
any of the officers, directors, employees, agents, attorneys-in-fact,
subsidiaries or affiliates of the ADMINISTRATIVE AGENT have made any
representations or warranties to it and that no act by the ADMINISTRATIVE AGENT
hereinafter taken, including any review of the affairs of the BORROWER shall be
deemed to constitute any representation or warranty by the ADMINISTRATIVE AGENT
to any LENDER. Each LENDER represents to the ADMINISTRATIVE AGENT that it has,
independently and without reliance upon the ADMINISTRATIVE AGENT or any other
LENDER, and based on such documents and information as it has deemed
appropriate, made its own appraisal of and investigation into the businesses,
operations, properties, financial and other conditions and creditworthiness of
the BORROWER and made its own decision to extend the LOANS to the BORROWER and
to enter into this AGREEMENT. Each LENDER also represents that it will,
independently and without reliance upon the ADMINISTRATIVE AGENT or any other
LENDER, and based on such documents and information as it shall deem
appropriate at the time, continue to make its own credit analysis, appraisals
and decisions in taking or not taking action under this AGREEMENT and the other
CREDIT DOCUMENTS, and to make such investigations as it deems necessary to
inform itself as to the businesses, operations, properties, financial and other
conditions and creditworthiness of the BORROWER. Except for notices, reports
and other documents expressly required to be furnished to the LENDERS by the
ADMINISTRATIVE AGENT hereunder or by the other CREDIT DOCUMENTS, the
ADMINISTRATIVE AGENT shall not have any duty or responsibility to provide any
LENDER with any credit or other information concerning the businesses,
operations, properties, financial and other conditions or creditworthiness of
the BORROWER which may come into the possession of the ADMINISTRATIVE AGENT or
any of its officers, directors, employees, agents, attorneys-in-fact,
subsidiaries or affiliates.

Section 9.8. Indemnification. Each LENDER agrees to indemnify the
ADMINISTRATIVE AGENT in the ADMINISTRATIVE AGENTS capacity as the appointed
agent of the LENDERS (to the extent not reimbursed by the BORROWER and without
limiting the obligations of the BORROWER to do so), ratably according to its
COMMITMENT PERCENTAGE, from and against any and all liabilities, obligations,
losses, damages, penalties, actions, judgments, suits, costs, expenses or
disbursements of any kind whatsoever which may at any time (including, without
limitation, at any time following the payment of the NOTES) be imposed on,
incurred by or asserted against the ADMINISTRATIVE AGENT in any way relating to
or arising out of this AGREEMENT or the other CREDIT DOCUMENTS, or any
documents contemplated by or referred to herein or therein or the transactions
contemplated hereby or thereby or any action taken or omitted by the
ADMINISTRATIVE AGENT under or in connection with any of the foregoing; provided
that no LENDER shall be liable for the payment of any portion of such
liabilities, obligations, losses, damages, penalties, actions, judgments,
suits, costs, expenses or disbursements resulting solely from the
ADMINISTRATIVE AGENTS gross negligence or willful misconduct. The agreements

enforcement rights. Each LENDER agrees that no LENDER shall have any right
individually to seek to realize upon any security granted by any of the CREDIT
DOCUMENTS or to individually exercise any of the remedies or rights of
enforcement provided by the CREDIT DOCUMENTS or as otherwise available under
applicable LAWS, it being agreed that such rights and remedies shall be
exercised only by the ADMINISTRATIVE AGENT for the benefit of the LENDERS in
accordance with the terms of the CREDIT DOCUMENTS.

Section 9.10. The Administrative Agent In Its Individual Capacity. The
ADMINISTRATIVE AGENT and the ADMINISTRATIVE AGENTS parent and subsidiaries and
affiliates may make loans to, accept deposits from and generally engage in any
kind of business with the BORROWER as though the ADMINISTRATIVE AGENT were not
an ADMINISTRATIVE AGENT hereunder. With respect to any LOAN made or renewed by
the ADMINISTRATIVE AGENT and any NOTE issued to the ADMINISTRATIVE AGENT, the
ADMINISTRATIVE AGENT shall have
the same rights and powers provided by this AGREEMENT and the other CREDIT
DOCUMENTS as any other LENDER and may exercise the same as though it were not
the ADMINISTRATIVE AGENT, and the terms LENDER and LENDERS shall include
the ADMINISTRATIVE AGENT in its individual lending capacity. The LENDERS, in

OBLIGATIONS.

Section 9.11. Removal Or Resignation Of The Administrative Agent;
Successor Administrative Agent. The ADMINISTRATIVE AGENT may be removed for

or resignation, the REQUIRED LENDERS, with the prior written approval of the
BORROWER (which approval shall not unreasonably be withheld or delayed, and
shall not be required if a DEFAULT or an EVENT OF DEFAULT shall have occurred
and be continuing), shall appoint a successor ADMINISTRATIVE AGENT, which
successor shall have minimum capital and surplus of at least Five Hundred
Million Dollars ($500,000,000.00). If a successor ADMINISTRATIVE AGENT has not
been so appointed or has not accepted such appointment within thirty (30) days
after the ADMINISTRATIVE AGENTS giving of notice of resignation, then the
ADMINISTRATIVE AGENT may, on behalf of the LENDERS, appoint a successor, which
successor shall have minimum capital and surplus of at least Five Hundred
Million Dollars ($500,000,000.00). Upon the acceptance of any appointment as
ADMINISTRATIVE AGENT hereunder by a successor ADMINISTRATIVE AGENT, such
ADMINISTRATIVE AGENT shall thereupon succeed to and become vested with all
rights, powers, privileges and duties of the retiring or removed ADMINISTRATIVE
AGENT, and the retiring or removed ADMINISTRATIVE AGENT shall be discharged
from its duties and obligations hereunder. After the resignation and removal
of any ADMINISTRATIVE AGENT, the provisions of this Article 9 shall continue in
effect with respect to actions taken or omitted to be taken by such
ADMINISTRATIVE AGENT while the retired or removed ADMINISTRATIVE AGENT was
acting in the capacity of ADMINISTRATIVE AGENT.

Section 9.12. Benefits Of Article 9. None of the provisions of this
Article 9 shall inure to the benefit of the BORROWER or any other PERSON other
than the ADMINISTRATIVE AGENT and the LENDERS; consequently, neither the
BORROWER nor any other PERSON shall be entitled to rely upon, or to raise as a
defense, in any manner whatsoever, the failure of the ADMINISTRATIVE AGENT or
any LENDER to comply with such provisions.

Section 9.13. Syndication And Documentation Agent. No LENDER identified
in this AGREEMENT as a SYNDICATION AGENT or as a DOCUMENTATION AGENT shall

shall be conclusive, in the absence of manifest error, and the BORROWER, the
ADMINISTRATIVE AGENT and the LENDERS may treat each PERSON whose name is
recorded in the REGISTER as a LENDER hereunder for all purposes of this

proportion than any such amount received by any other LENDER, then the LENDER
receiving such proportionately greater payment shall notify the ADMINISTRATIVE
AGENT of such receipt, and equitable adjustment will be made in the manner
stated in this Section so that, in effect, all such excess amounts will be
shared ratably among all of the LENDERS. The LENDER receiving such excess

##### 



shall be deemed to have done simultaneously
upon its receipt of a disproportionate payment) a participation in the
applicable OBLIGATIONS owed to such other LENDERS in such amount as shall
result in a ratable sharing by all LENDERS of such excess amount. If all or any
portion of such excess amount is thereafter recovered from the LENDER making
such purchase, such purchase shall be rescinded and
the purchase price restored to the extent of such recovery, together with
interest or other amounts, if any, required by LAW to be paid by the LENDER
making such purchase.

or any part thereof are subsequently invalidated, declared to be fraudulent or
preferential, set aside, avoided, and/or required to be repaid to a trustee,
receiver or any other party under any bankruptcy law, state or federal law,
common law or equitable cause, then, to the extent of such payment or proceeds
repaid, the OBLIGATIONS or part thereof intended to be satisfied shall be
revived and continued in full force and effect as if such payment or proceeds
had not been received by the LENDERS or the ADMINISTRATIVE AGENT.

Section 10.4. Amendments, Waivers And Consents. Except as expressly set
forth below in this Section, any term, covenant, agreement or condition of this
AGREEMENT or of any of the other CREDIT DOCUMENTS may be amended or waived by
the REQUIRED LENDERS on behalf of the LENDERS, and any consent may be given by
the REQUIRED LENDERS on behalf of the LENDERS; provided, however, that no
amendment, waiver or consent shall, without the prior written consent of all of
the LENDERS: (a) increase the principal amount or extend the time for payment
of any of the LOANS; (b) change any COMMITMENT PERCENTAGE or COMMITMENT AMOUNT
of any LENDER (except as specifically permitted to reflect an assignment

any of the LOANS or the time or times of payment of interest on any of the
LOANS; (d) increase or reduce the rate of interest or fees payable on any of

EVENT OF DEFAULT arising pursuant to a violation of either Section 6.3 or
Section 7.1 of this AGREEMENT; (or) (j) waive the condition precedent to
advances of proceeds of the LOANS set forth in Section 2.1.4 of this AGREEMENT
with respect to any then continuing EVENTS OF DEFAULT. Except as expressly
provided to the contrary in this AGREEMENT and with the exception of amendments
to any provision of Article 9 of this AGREEMENT, this AGREEMENT may not be
amended without the prior written consent of the BORROWER. The ADMINISTRATIVE
AGENT and all of the LENDERS may amend or modify any provision of Article 9 of
this AGREEMENT (excluding (i) those provisions relating to the consent rights
of the BORROWER, and (ii) those provisions relating to the qualifications of a
successor ADMINISTRATIVE AGENT) without the need for any consent or approval
from the BORROWER, it being acknowledged that the BORROWER is not a third-party
beneficiary of any of the provisions of Article 9 (without implying that the
BORROWER has any other third-party beneficiary rights).

Section 10.5. Set Off. The BORROWER agrees that, to the fullest extent
permitted by law, if any OBLIGATION shall be due and payable (by acceleration
or otherwise), each SECURED PARTY or PARTICIPANT (and any branch, subsidiary or
affiliate thereof) shall have the right, without notice to the BORROWER, to set
off against and to appropriate and apply to such OBLIGATION any indebtedness,
liability or obligation of any nature owing to the BORROWER by such SECURED
PARTY, PARTICIPANT (or branch, subsidiary or affiliate thereof), including but
not limited to all deposits (whether time or demand, general or special,
provisionally credited or finally credited, whether or not evidenced by a
certificate of deposit) now or hereafter maintained by the BORROWER with such
SECURED PARTY, PARTICIPANT

(or branch, subsidiary or affiliate thereof). Such right shall be
absolute and unconditional in all circumstances and, without limitation, shall
exist whether or not any notice or demand has been given to the BORROWER or any
other PERSON, whether such indebtedness, obligation or liability owed to the
BORROWER is contingent, absolute, matured or unmatured (it being agreed that
any such indebtedness, obligation or liability shall be deemed to be then due
and payable at the time of such set-off), and regardless of the existence or
adequacy of any collateral, guaranty or any other security, right or remedy
available. The rights provided by this Section are in addition to all other
rights of set-off and bankers LIEN and all other rights and remedies which the
SECURED PARTIES, any PARTICIPANT, or any branch, subsidiary or affiliate
thereof, may otherwise have under this AGREEMENT, any other CREDIT DOCUMENT,
at law or in equity, or otherwise, and nothing in this AGREEMENT or any other
CREDIT DOCUMENT shall be deemed a waiver or prohibition of or restriction on
the rights of set-off or bankers LIEN of any such PERSON.

Section 10.6. Secured Party Expenses. All reasonable
SECURED PARTY EXPENSES shall be paid by the BORROWER upon the demand of the
ADMINISTRATIVE AGENT, whether incurred prior to or after the date of CLOSING.

Section 10.7. Obligations Are Unconditional. The
payment and performance of the OBLIGATIONS shall be the absolute and
unconditional duty and obligation of the BORROWER, and shall be independent of
any defense or any rights of set-off, recoupment or counterclaim which the
BORROWER might otherwise have against any of the SECURED PARTIES. The BORROWER
shall pay the payments of the principal and interest to be made upon the
OBLIGATIONS, free of any deductions and without abatement, diminution or
set-off other than those herein expressly provided. Until the OBLIGATIONS have
been fully paid and performed, the BORROWER shall not: (a) suspend or
discontinue any payments required by the CREDIT DOCUMENTS; and (b) fail to
perform and observe all of the BORROWERS covenants and agreements set forth in
the CREDIT DOCUMENTS.

Section 10.8. Indemnity. The BORROWER agrees to
defend, indemnify and hold harmless each of the SECURED PARTIES and the
entities affiliated with the SECURED PARTIES and all of the SECURED PARTIES
and their respective affiliated entities employees, agents, officers and
directors, from and against any losses, penalties, fines, liabilities,
settlements, damages, costs and expenses, suffered in connection with any
claim, investigation, litigation or other proceeding (whether or not the
SECURED PARTY or an affiliated entity is a party thereto) and the prosecution
and defense thereof, arising out of or in any way connected with any CREDIT
DOCUMENT, including without limitation reasonable attorneys and consultants
fees, except to the extent that any of the foregoing directly result from the
gross negligence or willful misconduct of the party seeking indemnification
therefor. Notwithstanding any termination of this AGREEMENT or payment and
performance of the OBLIGATIONS, the indemnities provided for herein shall
continue in full force and effect and shall protect all of the above-described
PERSONS against events arising after such termination, payment or performance
as well as before.

Section 10.9. Incorporation. The terms and conditions
of the CREDIT DOCUMENTS are incorporated by reference and made a part hereof,
as if fully set forth herein.

Section 10.10. Waivers. The ADMINISTRATIVE AGENT at
any time or from time to time may waive all or any rights under this AGREEMENT
or any other CREDIT DOCUMENT upon the consent of the REQUIRED LENDERS or all
LENDERS as required by the terms of this AGREEMENT, but any waiver or
indulgence at any time or from time to time shall not constitute a future
waiver of performance or exact performance by the BORROWER.

Section 10.11. Continuing Obligation Of Borrower. The
terms, conditions, and covenants set forth herein
and in the CREDIT DOCUMENTS shall survive CLOSING and shall constitute a
continuing obligation of the BORROWER during the course of the transactions
contemplated herein. The LIENS and other security provided by this AGREEMENT
shall remain in effect so long as any OBLIGATION, whether direct or contingent,
is outstanding, unpaid, or unsatisfied or is being challenged or contested. At
such time as the OBLIGATIONS have been paid, performed and satisfied in full
and no INTEREST RATE





---



##### 



HEDGE or LETTER OF CREDIT remains in effect and provided
that no challenge or contest to such payment and performance or attempt to
avoid or set aside any payment upon the OBLIGATIONS is pending, the
ADMINISTRATIVE AGENT shall provide, at the BORROWERS expense, documentation
sufficient to release all LIENS of the ADMINISTRATIVE AGENT in the COLLATERAL;
and provided, that without limitation, the foregoing provisions of this Section
shall be subject to Section 2.12 hereof.

Section 10.12. Choice Of Law. The laws of the State of
Maryland (excluding, however, conflict of law principles) shall govern and be
applied to determine all issues relating to this AGREEMENT and the rights and
obligations of the parties hereto, including the validity, construction,
interpretation, and enforceability of this AGREEMENT and its various provisions
and the consequences and legal effect of all transactions and events which
resulted in the execution of this AGREEMENT or which occurred or were to occur
as a direct or indirect result of this AGREEMENT having been executed.

Section 10.13. Submission To Jurisdiction; Venue; Actions Against
Secured Parties. For purposes of any action, in law or in equity,
which is based directly or indirectly on this AGREEMENT, any other CREDIT
DOCUMENT or any matter related to this AGREEMENT or any other CREDIT DOCUMENT,
including any action for recognition or enforcement of any of the SECURED
PARTIES rights under the CREDIT DOCUMENTS or any judgment obtained by the
SECURED PARTIES in respect thereof, the BORROWER hereby:

Section 10.13.1. Jurisdiction. Irrevocably submits to
the non-exclusive general jurisdiction of the courts of the State of Maryland
and, if a basis for federal jurisdiction exists at any time, the courts of the
United States of America for the District of Maryland.

Section 10.13.2. Venue. Agrees that venue shall be
proper in the Circuit Court for Baltimore City, Maryland, the Circuit Court for
any county in the state of Maryland, as selected by the SECURED PARTIES, and,
if a basis for federal jurisdiction exists, the courts of the United States of
America for the District of Maryland.

Section 10.13.3. Waiver Of Objections To Venue. Waives
any right to object to the maintenance of any suit in any of the courts
specified in Section 10.13.2 above on the basis of improper venue or
convenience of forum. The BORROWER further agrees that it shall not institute
any suit or other action against any of the SECURED PARTIES, in law or in
equity, which is based directly or indirectly on this AGREEMENT, any other
CREDIT DOCUMENT or any matter related to this AGREEMENT or any other CREDIT
DOCUMENT, in any court other than a court specified in Section 10.13.2 above;
provided, that in any instance in which there is then pending a suit instituted
by the LENDER against the BORROWER in a court other than a court specified in
Section 10.13.2 above, the BORROWER may file in such suit any counterclaim
which it has against any of the SECURED PARTIES but only if such counterclaim
is a compulsory counterclaim and would be barred if not filed as a counterclaim
in such suit. The BORROWER agrees that any suit brought by it against any of
the SECURED PARTIES not in accordance with this paragraph should be forthwith
dismissed or transferred to a court specified in Section 10.13.2 above.

Section 10.14. Notices. Any notice required or
permitted by or in connection with this AGREEMENT shall be in writing (except
to the extent that telephonic notice is expressly authorized by the terms of
this AGREEMENT) and shall be made by facsimile (confirmed on the date the
facsimile is sent by one of the other methods of giving notice provided for in

GUARANTY AGREEMENT

(Martek Biosciences Boulder Corporation)

THIS GUARANTY AGREEMENT (GUARANTY) is made to be effective as of January
26, 2004, by MARTEK BIOSCIENCES BOULDER CORPORATION, a Delaware corporation
(GUARANTOR), for the benefit of MANUFACTURERS AND TRADERS TRUST COMPANY,
individually and in its capacity as the Administrative Agent (ADMINISTRATIVE
AGENT) for the LENDERS that are now or hereafter parties to a Loan And
Security Agreement (LOAN AGREEMENT) of even date herewith by and among MARTEK
BIOSCIENCES CORPORATION, a Delaware corporation (BORROWER), the
ADMINISTRATIVE AGENT, and the LENDERS. Hereafter, the ADMINISTRATIVE AGENT and
the LENDERS are collectively referred to as the SECURED PARTIES.

RECITALS

The LENDERS have been requested to extend loans to the BORROWER in the
maximum aggregate principal amount of Eighty-Five Million Dollars
($85,000,000.00) (collectively, LOANS). The LENDERS are unwilling to extend
the LOANS to the BORROWER unless the GUARANTOR agrees to guaranty to the
SECURED PARTIES the payment and performance by the BORROWER of all obligations
owed by the BORROWER to the SECURED PARTIES in connection with the LOANS. The
GUARANTOR will derive substantial direct and indirect economic benefits from
the extension of the LOANS by the SECURED PARTIES to the BORROWER, and has
agreed to execute and deliver this GUARANTY in order to induce the SECURED
PARTIES to extend the LOANS to the BORROWER. Hereafter, the LOAN AGREEMENT and
all documents and writings evidencing or securing the LOANS are collectively
referred to as the CREDIT DOCUMENTS.

NOW, THEREFORE, in consideration of these premises and other good and
valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, the GUARANTOR hereby agrees to provide to the SECURED PARTIES the
following guaranties and indemnifications.

Section 1. Guaranty. The GUARANTOR guarantees to the
SECURED PARTIES: (a) the payment of any and all sums now or hereafter due and
owing to the SECURED PARTIES by the BORROWER as a result of or in connection
with any and all existing or future indebtedness, liability, or obligation of
every kind, nature, type, and variety owed by the BORROWER to the SECURED
PARTIES from time to time, arising out of or related to the LOANS or the CREDIT
DOCUMENTS, whether direct or indirect, absolute or contingent, primary or
secondary, joint or several, unconditional or conditional, known or unknown,
liquidated or unliquidated, contractual or tortious, including, but not limited
to, all amounts of principal, interest, charges, reimbursements, advancements,
escrows, and fees; (b) that all sums now or hereafter due and owing by the
BORROWER to the SECURED PARTIES in connection with or arising from the LOANS
shall be paid when and as due, whether by reason of installment, maturity,
acceleration or otherwise, time being of the essence; (c) the payment and
performance of all indemnification obligations and duties to defend owed by the
BORROWER to the SECURED PARTIES in accordance with the terms of the CREDIT
DOCUMENTS; and (d) the timely, complete, continuous, and strict performance and
observance by the BORROWER of each of the terms, covenants, agreements and
conditions contained in the CREDIT DOCUMENTS. The GUARANTOR agrees to hold
harmless and indemnify the SECURED PARTIES from any and all costs and expenses,
including reasonable attorneys fees, incurred by the SECURED PARTIES as a
result of a failure by the BORROWER to satisfy its duties and obligations under
the CREDIT DOCUMENTS or the GUARANTORS failure to satisfy the duties and
obligations assumed by the GUARANTOR under this GUARANTY. As used in this
GUARANTY, the term OBLIGATIONS shall refer to the obligations of payment,
performance, and indemnification which the GUARANTOR has undertaken and assumed
pursuant to this GUARANTY, as described in this Section and in other Sections
of this GUARANTY.

Section 2. Nature Of Guaranty. This GUARANTY is
irrevocable and absolute and one of payment and not just collection, and is
direct, immediate, and primary. This GUARANTY makes the GUARANTOR a surety to
the SECURED PARTIES for the ratable and proportionate benefit of the SECURED
PARTIES with respect to the OBLIGATIONS and the equivalent of a co-obligor with
the BORROWER.

Section 3. Secured Parties Need Not Pursue Other
Rights. The SECURED PARTIES shall be under no obligation to pursue
any of the SECURED PARTIES rights and remedies against: (a) the BORROWER; (b)
any of the BORROWERS collateral securing the obligations of the BORROWER to
the SECURED PARTIES; (c) any other guarantor; or (d) any other guarantors
collateral, before pursuing the SECURED PARTIES rights and remedies against
the GUARANTOR.

Section 4. Certain Rights Of Secured Parties. The
GUARANTOR hereby assents to any and all terms and agreements between the
SECURED PARTIES and the BORROWER or between the SECURED PARTIES and any other
guarantor, and all amendments and modifications thereof, whether presently
existing or hereafter made and whether oral or in writing. The SECURED PARTIES
may, without compromising, impairing, diminishing, or in any way releasing the
GUARANTOR from the OBLIGATIONS and without notifying or obtaining the prior
approval of the GUARANTOR, at any time or from time to time: (a) waive or
excuse a default by the BORROWER or any other guarantor, or delay in the
exercise by the SECURED PARTIES of any or all of the SECURED PARTIES rights or
remedies with respect to such default or defaults; (b) grant extensions of time
for payment or performance by the BORROWER or any other guarantor; (c) release,
substitute, exchange, surrender, or add collateral of the BORROWER or of any
other guarantor, or waive, release, or subordinate, in whole or in part, any
lien or security interest held by the SECURED PARTIES on any real or personal
property securing payment or performance, in whole or in part, of the
obligations of the BORROWER to the SECURED PARTIES or of any other guarantor;
(d) release the BORROWER or any other guarantor; (e) apply payments made by the
BORROWER or by any other guarantor to any sums owed by the BORROWER to the
SECURED PARTIES, in any order or manner, or to any specific account or
accounts, as the SECURED PARTIES may elect; and (f) modify, change, renew,
extend, or amend in any respect any of the CREDIT DOCUMENTS or any guaranties,
security agreements or other agreements between the SECURED PARTIES and any
other guarantor, including without limitation modifications which increase the
amount of the OBLIGATIONS or extend the maturity of the OBLIGATIONS.

Section 5. Waivers By Guarantor. The GUARANTOR waives:
(a) any and all notices whatsoever with respect to this GUARANTY or with
respect to any of the obligations of the BORROWER to the SECURED PARTIES,
including, but not limited to, notice of (i) the SECURED PARTIES acceptance
hereof or the SECURED PARTIES intention to act, or the SECURED PARTIES
action, in reliance hereon, (ii) the present existence or future incurring of
any of the obligations of the BORROWER to the SECURED PARTIES or any terms or
amounts thereof or any change therein, (iii) any default by the BORROWER or any
surety, pledgor, grantor of security, guarantor or any person who has
guarantied or secured in whole or in part the obligations of the BORROWER to
the SECURED PARTIES, and (iv) the obtaining or release of any guaranty or
surety agreement, pledge, assignment, or other security for any of the
obligations of the BORROWER to the SECURED PARTIES; (b) presentment and demand
for payment of any sum due from the BORROWER or any other guarantor and protest
of nonpayment; and (c) demand for performance by the BORROWER or any other
guarantor.

Section 6. Unenforceability Of Obligations Of Borrower.
This GUARANTY shall be valid, binding, and enforceable even if the obligations
of the BORROWER to the SECURED PARTIES which are guaranteed hereby are now or
hereafter become invalid, unenforceable or uncollectible for any reason.

Section 7. No Conditions Precedent. This GUARANTY
shall be effective and enforceable immediately upon its execution. The
GUARANTOR acknowledges that no unsatisfied conditions precedent to the
effectiveness and enforceability of this GUARANTY exist as of the date of its
execution and that the effectiveness and enforceability of this GUARANTY are
not in any way conditioned or contingent upon any event, occurrence, or
happening, or upon any condition existing or coming into existence either
before or after the execution of this GUARANTY.

Section 8. No Duty To Disclose. The SECURED PARTIES
shall have no present or future duty or obligation to discover or to disclose
to the GUARANTOR any information, financial or otherwise, concerning the
BORROWER, any other guarantor, or any collateral securing either the
obligations of the BORROWER to the SECURED PARTIES or of any other person who
may have guarantied in whole or in part the obligations of the BORROWER to the
SECURED PARTIES. The GUARANTOR waives any right to claim or assert any such
duty or obligation on the part of the SECURED PARTIES. The GUARANTOR agrees to
obtain all information which the GUARANTOR considers either appropriate or
relevant to this GUARANTY from sources other than the SECURED PARTIES and to
become and remain at all times current and continuously apprised of all
information concerning the

2



---



##### 



BORROWER, other guarantors, and any collateral which is material and
relevant to the OBLIGATIONS of the GUARANTOR under this GUARANTY.

Section 9. Existing Or Future Guaranties. The
execution of this GUARANTY shall not discharge, terminate or in any way impair
or adversely affect the validity or enforceability of any other guaranty given
by the GUARANTOR to the SECURED PARTIES. The execution and delivery by the
GUARANTOR of any future guaranty for the benefit of the SECURED PARTIES shall
not discharge, terminate, or in any way impair or adversely affect the validity
or enforceability of this GUARANTY unless expressly stated therein. All
guaranties provided by the GUARANTOR to the SECURED PARTIES are intended to be
cumulative and shall remain in full force and effect unless and until
discharged and terminated in accordance with any expressly stated termination
provisions set forth therein.

Section 10. Cumulative Liability. The liability of the
GUARANTOR under this GUARANTY shall be cumulative to, and not in lieu of, the
GUARANTORS liability under any other CREDIT DOCUMENT or in any capacity other
than as GUARANTOR hereunder.

Section 11. Obligations Are Unconditional. The payment
and performance of the OBLIGATIONS shall be the absolute and unconditional duty
and obligation of the GUARANTOR, and shall be independent of any defense or any
rights of setoff, recoupment or counterclaim which the GUARANTOR might
otherwise have against the SECURED PARTIES, and the GUARANTOR shall pay and
perform these OBLIGATIONS, free of any deductions and without abatement,
diminution or setoff. Until such time as the OBLIGATIONS have been fully paid
and performed, the GUARANTOR: (a) shall not suspend or discontinue any
payments provided for herein; (b) shall perform and observe all of the
covenants and agreements contained in this GUARANTY; and (c) shall not
terminate or attempt to terminate this GUARANTY for any reason. No delay by
the SECURED PARTIES in making demand on the GUARANTOR for satisfaction of the
OBLIGATIONS shall prejudice or in any way impair the SECURED PARTIES ability
to enforce this GUARANTY.

Section 12. Defenses Against Borrower. The GUARANTOR
waives any right to assert against the SECURED PARTIES any defense (whether
legal or equitable), claim, counterclaim, or right of setoff or recoupment
which the GUARANTOR may now or hereafter have against the BORROWER or any other
guarantor.

Section 13. Events Of Default. The occurrence of any
of the following (each an EVENT OF DEFAULT) shall entitle the SECURED
PARTIES, without notice or demand, to accelerate and call due the OBLIGATIONS,
even if the SECURED PARTIES have not accelerated and called due the sums owed
to the SECURED PARTIES by the BORROWER: (a) the occurrence of an EVENT OF
DEFAULT, as such term is defined in the LOAN AGREEMENT; and (b) a failure of
the GUARANTOR to pay any of the OBLIGATIONS to the SECURED PARTIES at such time
as the nonpayment thereof by the BORROWER would constitute an EVENT OF
DEFAULT under the LOAN AGREEMENT.

Section 14. Expenses Of Collection And Attorneys Fees.
Should this GUARANTY be referred to an attorney for collection, the GUARANTOR
shall pay all of the SECURED PARTIES reasonable costs, fees and expenses
resulting from such referral, including reasonable attorneys fees, which the
SECURED PARTIES may incur, even though judgment has not been confessed or suit
has not been filed.

Section 15. Confession Of Judgment. Upon the occurrence
of an EVENT OF DEFAULT, the GUARANTOR authorizes any attorney designated by the
SECURED PARTIES or admitted to practice before any court of record in the
United States to appear on its behalf in any court in one or more proceedings,
or before any clerk thereof or prothonotary or other court official, and to
confess judgment against the GUARANTOR in the full amount due on this GUARANTY
(including principal, accrued interest and any and all charges, fees and costs)
plus attorneys fees equal to fifteen percent (15%) of the amount due, plus
court costs, all without prior notice or opportunity of the GUARANTOR for a
prior hearing. The GUARANTOR waives the benefit of any statutes, ordinances,
or rules of court which may be lawfully waived conferring upon it any right or
privilege of exemption, homestead rights, stay of execution, or supplementary
proceedings, or other relief from the enforcement or immediate enforcement of a
judgment or related proceedings on a judgment. The authority and power to
appear for and enter judgment against the GUARANTOR shall not be exhausted by
one or more exercises thereof, or by any imperfect exercise thereof, and shall
not be extinguished by any judgment entered pursuant thereto; such authority
and power may be exercised on one or more occasions from time to time, in the
same or different jurisdictions, as often as the SECURED PARTIES shall deem
necessary, convenient, or

proper. In the event that the SECURED PARTIES receive, as a result of
execution on a judgment confessed hereunder, attorneys fees which exceed the
actual legal fees incurred by the SECURED PARTIES in connection with the
enforcement of this GUARANTY, then upon full and final payment of all other
sums due and owing to the SECURED PARTIES in accordance with this GUARANTY and
the payment to the SECURED PARTIES of the actual attorneys fees incurred by
the SECURED PARTIES, the SECURED PARTIES shall remit such excess amount of
attorneys fees to the GUARANTOR.

Section 16. Interest Rate. If judgment is entered
against the GUARANTOR on this GUARANTY, the amount of the judgment entered
(which, unless applicable law specifically provides to the contrary, includes
all principal, prejudgment interest, late charges, prepayment charges if any
are provided for, collection expenses, attorneys fees, and court costs) shall
bear interest at the highest rate after default authorized by the CREDIT
DOCUMENTS (DEFAULT RATE) as of the date of entry of the judgment to the
extent permitted by applicable law. In the event any statute or rule of court
specifies the rate of interest which a judgment on this GUARANTY may bear or
the amount on which such interest rate may apply and such rate or amount is
less than that called for in the preceding sentence absent a restriction under
applicable law, the GUARANTOR: (a) agrees to pay to the order of the SECURED
PARTIES an amount as will equal the interest computed at the DEFAULT RATE on
the judgment amount (which, for this purpose, shall be considered to include
all principal, prejudgment interest, late charges, prepayment charges if any
are provided for, collection expense fees, attorneys fees, and court costs)
less the interest due on the amount of the judgment which bears judgment
interest; and (b) authorizes the confession of judgment pursuant to the
confession of judgment provision of this GUARANTY if the GUARANTOR fails to
make payment thereof.

Section 17. Enforcement During Bankruptcy Of Borrower.
Enforcement of this GUARANTY shall not be stayed or in any way delayed as a
result of the filing of a petition under the United States Bankruptcy
Code, as amended, by or against the BORROWER. Should the SECURED
PARTIES be required to obtain an order of the United States Bankruptcy Court to
begin enforcement of this GUARANTY after the filing of a petition under the
United States Bankruptcy Code, as amended, by or against the
BORROWER, the GUARANTOR hereby consents to this relief and agrees to file or
cause to be filed all appropriate pleadings to evidence and effectuate such
consent and to enable the SECURED PARTIES to obtain the relief requested.

Section 18. Remedies Cumulative. All of the SECURED
PARTIES rights and remedies shall be cumulative and any failure of the SECURED
PARTIES to exercise any right hereunder shall not be construed as a waiver of
the right to exercise the same or any other right at any time, and from time to
time, thereafter.

Section 19. Continuing Guaranty. This GUARANTY is a
continuing guaranty of all existing and future obligations of the BORROWER to
the SECURED PARTIES arising out of or relating to the LOANS or the CREDIT
DOCUMENTS and may not be terminated by the GUARANTOR until after the repayment
and performance in full of the LOANS and all of the OBLIGATIONS and in the
absence of any pending or threatened proceedings to avoid or recover any
payment previously received by the SECURED PARTIES upon the LOANS or any of the
OBLIGATIONS. All obligations and duties of indemnification assumed by the
GUARANTOR under this GUARANTY and the obligations of the GUARANTOR to guaranty
any covenants or agreements of indemnification or duties to defend provided by
the BORROWER to the SECURED PARTIES shall survive the repayment of the LOANS
and the termination of this GUARANTY.

Section 20. Reinstatement. If at any time any payment,
or portion thereof, made by, or for the account of, the BORROWER or the
GUARANTOR on account of any of the obligations and liabilities under any of the
CREDIT DOCUMENTS is set aside by any court or trustee having jurisdiction as a
voidable preference, or fraudulent conveyance or must otherwise be restored or
returned by the SECURED PARTIES to the BORROWER or any other person or entity
under any insolvency, bankruptcy or other federal and/or state law or as a
result of any dissolution, liquidation or reorganization of the BORROWER or any
other person or entity, or for any other reason, the GUARANTOR hereby agrees
that this GUARANTY shall continue and remain in full force and effect or be
reinstated, as the case may be, all as though such payment(s) had not been
made.

Section 21. Rights Of Subrogation, Etc. In the event
the GUARANTOR pays any sum to or for the benefit of the SECURED PARTIES
pursuant to this GUARANTY, the GUARANTOR may not enforce any right of
contribution, indemnification, exoneration, reimbursement, subrogation or other
right or remedy against the BORROWER, any other guarantor, or any collateral,
whether real, personal, or mixed, securing the obligations of the

4



---



##### 



BORROWER to the SECURED PARTIES or the obligations of any other guarantor
to the SECURED PARTIES until such time as the SECURED PARTIES have been paid in
full and has no further claim against the BORROWER, any other guarantor, or any
collateral. The GUARANTOR waives and releases any claim which the GUARANTOR
hereafter may have against the SECURED PARTIES if some action of the SECURED
PARTIES, whether intentional or negligent, impairs, destroys, or in any way
adversely affects any right of contribution, indemnification, exoneration,
reimbursement, subrogation, or the like which the GUARANTOR may have upon the
payment of any sum to or for the benefit of the SECURED PARTIES pursuant to
this GUARANTY.

Section 22. Subordination Of Certain Indebtedness. If
the GUARANTOR advances any sums to the BORROWER or its successors or assigns or
if the BORROWER or its successors or assigns shall hereafter become indebted to
the GUARANTOR, such sums and indebtedness shall be subordinate in all respects
to the amounts then or thereafter due and owing to the SECURED PARTIES by the
BORROWER; provided, however, that unless an EVENT OF DEFAULT shall have
occurred and be continuing the BORROWER shall be permitted to repay such sums
and indebtedness to the GUARANTOR.

Section 23. Renewals, Etc. This GUARANTY shall apply
to all sums now or hereafter owed by the BORROWER to the SECURED PARTIES and to
all extensions, modifications, amendments, renewals, substitutions, and
refinancings thereof.

Section 24. Choice Of Law. The laws of the State of
Maryland (excluding, however, conflict of law principles) shall govern and be
applied to determine all issues relating to this GUARANTY and the rights and
obligations of the parties hereto, including the validity, construction,
interpretation, and enforceability of this GUARANTY and its various provisions
and the consequences and legal effect of all transactions and events which
resulted in the issuance of this GUARANTY or which occurred or were to occur as
a direct or indirect result of this GUARANTY having been executed.

Section 25. Consent To Jurisdiction; Agreement As To
Venue. The GUARANTOR irrevocably consents to the non-exclusive
jurisdiction of the courts of the State of Maryland, including all United
States District Courts located in Maryland. The GUARANTOR agrees that venue
shall be proper in any circuit court of the State of Maryland selected by the
SECURED PARTIES or in any United States District Court located in Maryland and
waives any right to object to the maintenance of a suit in any of the state or
federal courts of the State of Maryland on the basis of improper venue or of
inconvenience of forum.

Section 26. Invalidity Of Any Part. If any provision
or part of any provision of this GUARANTY shall for any reason be held invalid,
illegal, or unenforceable in any respect, such invalidity, illegality, or
unenforceability shall not affect any other provisions or the remaining part of
any effective provisions of this GUARANTY, and this GUARANTY shall be construed
as if such invalid, illegal, or unenforceable provision or part thereof had
never been contained herein, but only to the extent of its invalidity,
illegality, or unenforceability.

Section 27. Amendment Or Waiver. This GUARANTY may be
amended only by a writing duly executed by the GUARANTOR and the ADMINISTRATIVE
AGENT with the consent of those SECURED PARTIES as may be required under the
LOAN AGREEMENT. No waiver by the SECURED PARTIES of any of the provisions of
this GUARANTY or any of the rights or remedies of the SECURED PARTIES with
respect hereto shall be considered effective or enforceable unless in writing.

Section 28. Notices. Any notice required or permitted
by or in connection with this GUARANTY shall be in writing and shall be made by

methods of giving notice provided for in this Section) or by hand delivery, by

addressed to the SECURED PARTIES or the GUARANTOR at the appropriate address

calendar day after delivery to Federal Express or similar overnight delivery
service, or three (3) calendar days after the date of mailing, independent of
the date of actual delivery or whether delivery is ever in fact made, as the

GUARANTY AGREEMENT

(Martek Biosciences Kingstree Corporation)

THIS GUARANTY AGREEMENT (GUARANTY) is made to be effective as of January
26, 2004, by MARTEK BIOSCIENCES KINGSTREE CORPORATION, a Delaware corporation
(GUARANTOR), for the benefit of MANUFACTURERS AND TRADERS TRUST COMPANY,
individually and in its capacity as the Administrative Agent (ADMINISTRATIVE
AGENT) for the LENDERS that are now or hereafter parties to a Loan And
Security Agreement (LOAN AGREEMENT) of even date herewith by and among MARTEK
BIOSCIENCES CORPORATION, a Delaware corporation (BORROWER), the
ADMINISTRATIVE AGENT, and the LENDERS. Hereafter, the ADMINISTRATIVE AGENT and
the LENDERS are collectively referred to as the SECURED PARTIES.

RECITALS

The LENDERS have been requested to extend loans to the BORROWER in the
maximum aggregate principal amount of Eighty-Five Million Dollars
($85,000,000.00) (collectively, LOANS). The LENDERS are unwilling to extend
the LOANS to the BORROWER unless the GUARANTOR agrees to guaranty to the
SECURED PARTIES the payment and performance by the BORROWER of all obligations
owed by the BORROWER to the SECURED PARTIES in connection with the LOANS. The
GUARANTOR will derive substantial direct and indirect economic benefits from
the extension of the LOANS by the SECURED PARTIES to the BORROWER, and has
agreed to execute and deliver this GUARANTY in order to induce the SECURED
PARTIES to extend the LOANS to the BORROWER. Hereafter, the LOAN AGREEMENT and
all documents and writings evidencing or securing the LOANS are collectively
referred to as the CREDIT DOCUMENTS.

NOW, THEREFORE, in consideration of these premises and other good and
valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, the GUARANTOR hereby agrees to provide to the SECURED PARTIES the
following guaranties and indemnifications.

Section 1. Guaranty. The GUARANTOR guarantees to the
SECURED PARTIES: (a) the payment of any and all sums now or hereafter due and
owing to the SECURED PARTIES by the BORROWER as a result of or in connection
with any and all existing or future indebtedness, liability, or obligation of
every kind, nature, type, and variety owed by the BORROWER to the SECURED
PARTIES from time to time, arising out of or related to the LOANS or the CREDIT
DOCUMENTS, whether direct or indirect, absolute or contingent, primary or
secondary, joint or several, unconditional or conditional, known or unknown,
liquidated or unliquidated, contractual or tortious, including, but not limited
to, all amounts of principal, interest, charges, reimbursements, advancements,
escrows, and fees; (b) that all sums now or hereafter due and owing by the
BORROWER to the SECURED PARTIES in connection with or arising from the LOANS
shall be paid when and as due, whether by reason of installment, maturity,
acceleration or otherwise, time being of the essence; (c) the payment and
performance of all indemnification obligations and duties to defend owed by the
BORROWER to the SECURED PARTIES in accordance with the terms of the CREDIT
DOCUMENTS; and (d) the timely, complete, continuous, and strict performance and
observance by the BORROWER of each of the terms, covenants, agreements and
conditions contained in the CREDIT DOCUMENTS. The GUARANTOR agrees to hold
harmless and indemnify the SECURED PARTIES from any and all costs and expenses,
including reasonable attorneys fees, incurred by the SECURED PARTIES as a
result of a failure by the BORROWER to satisfy its duties and obligations under
the CREDIT DOCUMENTS or the GUARANTORS failure to satisfy the duties and
obligations assumed by the GUARANTOR under this GUARANTY. As used in this
GUARANTY, the term OBLIGATIONS shall refer to the obligations of payment,
performance, and indemnification which the GUARANTOR has undertaken and assumed
pursuant to this GUARANTY, as described in this Section and in other Sections
of this GUARANTY.

Section 2. Nature Of Guaranty. This GUARANTY is
irrevocable and absolute and one of payment and not just collection, and is
direct, immediate, and primary. This GUARANTY makes the GUARANTOR a surety to
the SECURED PARTIES for the ratable and proportionate benefit of the SECURED
PARTIES with respect to the OBLIGATIONS and the equivalent of a co-obligor with
the BORROWER.

Section 3. Secured Parties Need Not Pursue Other
Rights. The SECURED PARTIES shall be under no obligation to pursue
any of the SECURED PARTIES rights and remedies against: (a) the BORROWER; (b)
any of the BORROWERS collateral securing the obligations of the BORROWER to
the SECURED PARTIES; (c) any other guarantor; or (d) any other guarantors
collateral, before pursuing the SECURED PARTIES rights and remedies against
the GUARANTOR.

Section 4. Certain Rights Of Secured Parties. The
GUARANTOR hereby assents to any and all terms and agreements between the
SECURED PARTIES and the BORROWER or between the SECURED PARTIES and any other
guarantor, and all amendments and modifications thereof, whether presently
existing or hereafter made and whether oral or in writing. The SECURED PARTIES
may, without compromising, impairing, diminishing, or in any way releasing the
GUARANTOR from the OBLIGATIONS and without notifying or obtaining the prior
approval of the GUARANTOR, at any time or from time to time: (a) waive or
excuse a default by the BORROWER or any other guarantor, or delay in the
exercise by the SECURED PARTIES of any or all of the SECURED PARTIES rights or
remedies with respect to such default or defaults; (b) grant extensions of time
for payment or performance by the BORROWER or any other guarantor; (c) release,
substitute, exchange, surrender, or add collateral of the BORROWER or of any
other guarantor, or waive, release, or subordinate, in whole or in part, any
lien or security interest held by the SECURED PARTIES on any real or personal
property securing payment or performance, in whole or in part, of the
obligations of the BORROWER to the SECURED PARTIES or of any other guarantor;
(d) release the BORROWER or any other guarantor; (e) apply payments made by the
BORROWER or by any other guarantor to any sums owed by the BORROWER to the
SECURED PARTIES, in any order or manner, or to any specific account or
accounts, as the SECURED PARTIES may elect; and (f) modify, change, renew,
extend, or amend in any respect any of the CREDIT DOCUMENTS or any guaranties,
security agreements or other agreements between the SECURED PARTIES and any
other guarantor, including without limitation modifications which increase the
amount of the OBLIGATIONS or extend the maturity of the OBLIGATIONS.

Section 5. Waivers By Guarantor. The GUARANTOR waives:
(a) any and all notices whatsoever with respect to this GUARANTY or with
respect to any of the obligations of the BORROWER to the SECURED PARTIES,
including, but not limited to, notice of (i) the SECURED PARTIES acceptance
hereof or the SECURED PARTIES intention to act, or the SECURED PARTIES
action, in reliance hereon, (ii) the present existence or future incurring of
any of the obligations of the BORROWER to the SECURED PARTIES or any terms or
amounts thereof or any change therein, (iii) any default by the BORROWER or any
surety, pledgor, grantor of security, guarantor or any person who has
guarantied or secured in whole or in part the obligations of the BORROWER to
the SECURED PARTIES, and (iv) the obtaining or release of any guaranty or
surety agreement, pledge, assignment, or other security for any of the
obligations of the BORROWER to the SECURED PARTIES; (b) presentment and demand
for payment of any sum due from the BORROWER or any other guarantor and protest
of nonpayment; and (c) demand for performance by the BORROWER or any other
guarantor.

Section 6. Unenforceability Of Obligations Of Borrower.
This GUARANTY shall be valid, binding, and enforceable even if the obligations
of the BORROWER to the SECURED PARTIES which are guaranteed hereby are now or
hereafter become invalid, unenforceable or uncollectible for any reason.

Section 7. No Conditions Precedent. This GUARANTY
shall be effective and enforceable immediately upon its execution. The
GUARANTOR acknowledges that no unsatisfied conditions precedent to the
effectiveness and enforceability of this GUARANTY exist as of the date of its
execution and that the effectiveness and enforceability of this GUARANTY are
not in any way conditioned or contingent upon any event, occurrence, or
happening, or upon any condition existing or coming into existence either
before or after the execution of this GUARANTY.

Section 8. No Duty To Disclose. The SECURED PARTIES
shall have no present or future duty or obligation to discover or to disclose
to the GUARANTOR any information, financial or otherwise, concerning the
BORROWER, any other guarantor, or any collateral securing either the
obligations of the BORROWER to the SECURED PARTIES or of any other person who
may have guarantied in whole or in part the obligations of the BORROWER to the
SECURED PARTIES. The GUARANTOR waives any right to claim or assert any such
duty or obligation on the part of the SECURED PARTIES. The GUARANTOR agrees to
obtain all information which the GUARANTOR considers either appropriate or
relevant to this GUARANTY from sources other than the SECURED PARTIES and to
become and remain at all times current and continuously apprised of all
information concerning the

2



---



##### 



BORROWER, other guarantors, and any collateral which is material and
relevant to the OBLIGATIONS of the GUARANTOR under this GUARANTY.

Section 9. Existing Or Future Guaranties. The
execution of this GUARANTY shall not discharge, terminate or in any way impair
or adversely affect the validity or enforceability of any other guaranty given
by the GUARANTOR to the SECURED PARTIES. The execution and delivery by the
GUARANTOR of any future guaranty for the benefit of the SECURED PARTIES shall
not discharge, terminate, or in any way impair or adversely affect the validity
or enforceability of this GUARANTY unless expressly stated therein. All
guaranties provided by the GUARANTOR to the SECURED PARTIES are intended to be
cumulative and shall remain in full force and effect unless and until
discharged and terminated in accordance with any expressly stated termination
provisions set forth therein.

Section 10. Cumulative Liability. The liability of the
GUARANTOR under this GUARANTY shall be cumulative to, and not in lieu of, the
GUARANTORS liability under any other CREDIT DOCUMENT or in any capacity other
than as GUARANTOR hereunder.

Section 11. Obligations Are Unconditional. The payment
and performance of the OBLIGATIONS shall be the absolute and unconditional duty
and obligation of the GUARANTOR, and shall be independent of any defense or any
rights of setoff, recoupment or counterclaim which the GUARANTOR might
otherwise have against the SECURED PARTIES, and the GUARANTOR shall pay and
perform these OBLIGATIONS, free of any deductions and without abatement,
diminution or setoff. Until such time as the OBLIGATIONS have been fully paid
and performed, the GUARANTOR: (a) shall not suspend or discontinue any
payments provided for herein; (b) shall perform and observe all of the
covenants and agreements contained in this GUARANTY; and (c) shall not
terminate or attempt to terminate this GUARANTY for any reason. No delay by
the SECURED PARTIES in making demand on the GUARANTOR for satisfaction of the
OBLIGATIONS shall prejudice or in any way impair the SECURED PARTIES ability
to enforce this GUARANTY.

Section 12. Defenses Against Borrower. The GUARANTOR
waives any right to assert against the SECURED PARTIES any defense (whether
legal or equitable), claim, counterclaim, or right of setoff or recoupment
which the GUARANTOR may now or hereafter have against the BORROWER or any other
guarantor.

Section 13. Events Of Default. The occurrence of any
of the following (each an EVENT OF DEFAULT) shall entitle the SECURED
PARTIES, without notice or demand, to accelerate and call due the OBLIGATIONS,
even if the SECURED PARTIES have not accelerated and called due the sums owed
to the SECURED PARTIES by the BORROWER: (a) the occurrence of an EVENT OF
DEFAULT, as such term is defined in the LOAN AGREEMENT; and (b) a failure of
the GUARANTOR to pay any of the OBLIGATIONS to the SECURED PARTIES at such time
as the nonpayment thereof by the BORROWER would constitute an EVENT OF
DEFAULT under the LOAN AGREEMENT.

Section 14. Expenses Of Collection And Attorneys Fees.
Should this GUARANTY be referred to an attorney for collection, the GUARANTOR
shall pay all of the SECURED PARTIES reasonable costs, fees and expenses
resulting from such referral, including reasonable attorneys fees, which the
SECURED PARTIES may incur, even though judgment has not been confessed or suit
has not been filed.

Section 15. Confession Of Judgment. Upon the occurrence
of an EVENT OF DEFAULT, the GUARANTOR authorizes any attorney designated by the
SECURED PARTIES or admitted to practice before any court of record in the
United States to appear on its behalf in any court in one or more proceedings,
or before any clerk thereof or prothonotary or other court official, and to
confess judgment against the GUARANTOR in the full amount due on this GUARANTY
(including principal, accrued interest and any and all charges, fees and costs)
plus attorneys fees equal to fifteen percent (15%) of the amount due, plus
court costs, all without prior notice or opportunity of the GUARANTOR for a
prior hearing. The GUARANTOR waives the benefit of any statutes, ordinances,
or rules of court which may be lawfully waived conferring upon it any right or
privilege of exemption, homestead rights, stay of execution, or supplementary
proceedings, or other relief from the enforcement or immediate enforcement of a
judgment or related proceedings on a judgment. The authority and power to
appear for and enter judgment against the GUARANTOR shall not be exhausted by
one or more exercises thereof, or by any imperfect exercise thereof, and shall
not be extinguished by any judgment entered pursuant thereto; such authority
and power may be exercised on one or more occasions from time to time, in the
same or different jurisdictions, as often as the SECURED PARTIES shall deem
necessary, convenient, or

3

##### 



proper. In the event that the SECURED PARTIES receive, as a result of
execution on a judgment confessed hereunder, attorneys fees which exceed the
actual legal fees incurred by the SECURED PARTIES in connection with the
enforcement of this GUARANTY, then upon full and final payment of all other
sums due and owing to the SECURED PARTIES in accordance with this GUARANTY and
the payment to the SECURED PARTIES of the actual attorneys fees incurred by
the SECURED PARTIES, the SECURED PARTIES shall remit such excess amount of
attorneys fees to the GUARANTOR.

Section 16. Interest Rate. If judgment is entered
against the GUARANTOR on this GUARANTY, the amount of the judgment entered
(which, unless applicable law specifically provides to the contrary, includes
all principal, prejudgment interest, late charges, prepayment charges if any
are provided for, collection expenses, attorneys fees, and court costs) shall
bear interest at the highest rate after default authorized by the CREDIT
DOCUMENTS (DEFAULT RATE) as of the date of entry of the judgment to the
extent permitted by applicable law. In the event any statute or rule of court
specifies the rate of interest which a judgment on this GUARANTY may bear or
the amount on which such interest rate may apply and such rate or amount is
less than that called for in the preceding sentence absent a restriction under
applicable law, the GUARANTOR: (a) agrees to pay to the order of the SECURED
PARTIES an amount as will equal the interest computed at the DEFAULT RATE on
the judgment amount (which, for this purpose, shall be considered to include
all principal, prejudgment interest, late charges, prepayment charges if any
are provided for, collection expense fees, attorneys fees, and court costs)
less the interest due on the amount of the judgment which bears judgment
interest; and (b) authorizes the confession of judgment pursuant to the
confession of judgment provision of this GUARANTY if the GUARANTOR fails to
make payment thereof.

Section 17. Enforcement During Bankruptcy Of Borrower.
Enforcement of this GUARANTY shall not be stayed or in any way delayed as a
result of the filing of a petition under the United States Bankruptcy
Code, as amended, by or against the BORROWER. Should the SECURED
PARTIES be required to obtain an order of the United States Bankruptcy Court to
begin enforcement of this GUARANTY after the filing of a petition under the
United States Bankruptcy Code, as amended, by or against the
BORROWER, the GUARANTOR hereby consents to this relief and agrees to file or
cause to be filed all appropriate pleadings to evidence and effectuate such
consent and to enable the SECURED PARTIES to obtain the relief requested.

Section 18. Remedies Cumulative. All of the SECURED
PARTIES rights and remedies shall be cumulative and any failure of the SECURED
PARTIES to exercise any right hereunder shall not be construed as a waiver of
the right to exercise the same or any other right at any time, and from time to
time, thereafter.

Section 19. Continuing Guaranty. This GUARANTY is a
continuing guaranty of all existing and future obligations of the BORROWER to
the SECURED PARTIES arising out of or relating to the LOANS or the CREDIT
DOCUMENTS and may not be terminated by the GUARANTOR until after the repayment
and performance in full of the LOANS and all of the OBLIGATIONS and in the
absence of any pending or threatened proceedings to avoid or recover any
payment previously received by the SECURED PARTIES upon the LOANS or any of the
OBLIGATIONS. All obligations and duties of indemnification assumed by the
GUARANTOR under this GUARANTY and the obligations of the GUARANTOR to guaranty
any covenants or agreements of indemnification or duties to defend provided by
the BORROWER to the SECURED PARTIES shall survive the repayment of the LOANS
and the termination of this GUARANTY.

Section 20. Reinstatement. If at any time any payment,
or portion thereof, made by, or for the account of, the BORROWER or the
GUARANTOR on account of any of the obligations and liabilities under any of the
CREDIT DOCUMENTS is set aside by any court or trustee having jurisdiction as a
voidable preference, or fraudulent conveyance or must otherwise be restored or
returned by the SECURED PARTIES to the BORROWER or any other person or entity
under any insolvency, bankruptcy or other federal and/or state law or as a
result of any dissolution, liquidation or reorganization of the BORROWER or any
other person or entity, or for any other reason, the GUARANTOR hereby agrees
that this GUARANTY shall continue and remain in full force and effect or be
reinstated, as the case may be, all as though such payment(s) had not been
made.

Section 21. Rights Of Subrogation, Etc. In the event
the GUARANTOR pays any sum to or for the benefit of the SECURED PARTIES
pursuant to this GUARANTY, the GUARANTOR may not enforce any right of
contribution, indemnification, exoneration, reimbursement, subrogation or other
right or remedy against the BORROWER, any other guarantor, or any collateral,
whether real, personal, or mixed, securing the obligations of the

4



---



##### 



BORROWER to the SECURED PARTIES or the obligations of any other guarantor
to the SECURED PARTIES until such time as the SECURED PARTIES have been paid in
full and has no further claim against the BORROWER, any other guarantor, or any
collateral. The GUARANTOR waives and releases any claim which the GUARANTOR
hereafter may have against the SECURED PARTIES if some action of the SECURED
PARTIES, whether intentional or negligent, impairs, destroys, or in any way
adversely affects any right of contribution, indemnification, exoneration,
reimbursement, subrogation, or the like which the GUARANTOR may have upon the
payment of any sum to or for the benefit of the SECURED PARTIES pursuant to
this GUARANTY.

Section 22. Subordination Of Certain Indebtedness. If
the GUARANTOR advances any sums to the BORROWER or its successors or assigns or
if the BORROWER or its successors or assigns shall hereafter become indebted to
the GUARANTOR, such sums and indebtedness shall be subordinate in all respects
to the amounts then or thereafter due and owing to the SECURED PARTIES by the
BORROWER; provided, however, that unless an EVENT OF DEFAULT shall have
occurred and be continuing the BORROWER shall be permitted to repay such sums
and indebtedness to the GUARANTOR.

Section 23. Renewals, Etc. This GUARANTY shall apply
to all sums now or hereafter owed by the BORROWER to the SECURED PARTIES and to
all extensions, modifications, amendments, renewals, substitutions, and
refinancings thereof.

Section 24. Choice Of Law. The laws of the State of
Maryland (excluding, however, conflict of law principles) shall govern and be
applied to determine all issues relating to this GUARANTY and the rights and
obligations of the parties hereto, including the validity, construction,
interpretation, and enforceability of this GUARANTY and its various provisions
and the consequences and legal effect of all transactions and events which
resulted in the issuance of this GUARANTY or which occurred or were to occur as
a direct or indirect result of this GUARANTY having been executed.

Section 25. Consent To Jurisdiction; Agreement As To
Venue. The GUARANTOR irrevocably consents to the non-exclusive
jurisdiction of the courts of the State of Maryland, including all United
States District Courts located in Maryland. The GUARANTOR agrees that venue
shall be proper in any circuit court of the State of Maryland selected by the
SECURED PARTIES or in any United States District Court located in Maryland and
waives any right to object to the maintenance of a suit in any of the state or
federal courts of the State of Maryland on the basis of improper venue or of
inconvenience of forum.

Section 26. Invalidity Of Any Part. If any provision
or part of any provision of this GUARANTY shall for any reason be held invalid,
illegal, or unenforceable in any respect, such invalidity, illegality, or
unenforceability shall not affect any other provisions or the remaining part of
any effective provisions of this GUARANTY, and this GUARANTY shall be construed
as if such invalid, illegal, or unenforceable provision or part thereof had
never been contained herein, but only to the extent of its invalidity,
illegality, or unenforceability.

Section 27. Amendment Or Waiver. This GUARANTY may be
amended only by a writing duly executed by the GUARANTOR and the ADMINISTRATIVE
AGENT with the consent of those SECURED PARTIES as may be required under the
LOAN AGREEMENT. No waiver by the SECURED PARTIES of any of the provisions of
this GUARANTY or any of the rights or remedies of the SECURED PARTIES with
respect hereto shall be considered effective or enforceable unless in writing.

Section 28. Notices. Any notice required or permitted
by or in connection with this GUARANTY shall be in writing and shall be made by

methods of giving notice provided for in this Section) or by hand delivery, by
Federal Express, or other similar overnight delivery service, or by certified
mail, unrestricted delivery, return receipt requested, postage prepaid,
addressed to the SECURED PARTIES or the GUARANTOR at the appropriate address
set forth below or to such other address as may be hereafter specified by
written notice by the SECURED PARTIES or the GUARANTOR. Notice shall be
considered given as of the date of the facsimile or the hand delivery, one (1)
calendar day after delivery to Federal Express or similar overnight delivery
service, or three (3) calendar days after the date of mailing, independent of
the date of actual delivery or whether delivery is ever in fact made, as the

acts and promises set forth in this Article 4:

Section 4.1. Payment And Performance. All OBLIGATIONS
shall be paid and performed in full when and as due.

Section 4.2. Casualty Insurance. Until the full and
complete satisfaction of all of the OBLIGATIONS, the GUARANTOR shall maintain
for all of its respective assets and properties, whether real, personal, or
mixed and including but not limited to the COLLATERAL, fire and extended
coverage casualty insurance in amounts satisfactory to the ADMINISTRATIVE AGENT
in the exercise of its reasonable discretion and sufficient to prevent any
co-insurance liability (which amount shall be the full insurable value of the
assets and properties insured unless the ADMINISTRATIVE AGENT in writing agree
to a lesser amount), naming the ADMINISTRATIVE AGENT as sole loss payee with
respect to the COLLATERAL. The GUARANTOR shall submit to the ADMINISTRATIVE
AGENT satisfactory evidence of the originals of the casualty insurance policies

levies imposed upon it or on any of its property or which it is required to
withhold and pay over to the taxing authority or which it must pay on its
income, except where contested in good faith, by appropriate proceedings and at
its own cost and expense; provided, however, that the GUARANTOR shall not be
deemed to be contesting in good faith by appropriate proceedings unless: (a)
such proceedings operate to prevent the taxing authority from attempting to
collect the taxes, assessments or charges; (b) the COLLATERAL is not subject to
sale, forfeiture or loss during such proceedings; (c) the GUARANTORS contest
does not subject the SECURED PARTIES to any claim by the taxing authority or
any other person; (d) the GUARANTOR establishes appropriate reserves in
accordance with generally accepted accounting principles for the payment of all
taxes, assessments, charges, levies, legal fees, court costs and other expenses
for which the GUARANTOR would be liable if it is unsuccessful in its contest;

amounts determined to be payable, including but not limited to all taxes,

as the ADMINISTRATIVE AGENT reasonably determines to be necessary to perfect,

6

##### 



confirm, establish, reestablish, continue, or complete the security interests
and liens in the COLLATERAL. If the GUARANTOR fails to execute any such
document within five (5) business days of being requested to do so by the
SECURED PARTIES, the GUARANTOR hereby appoints the ADMINISTRATIVE AGENT or any
officer of the ADMINISTRATIVE AGENT as the GUARANTORS attorney in fact for
purposes of executing such documents in the GUARANTORS name, place and stead,
which power of attorney shall be considered as coupled with an interest and
irrevocable.

Section 4.8. Advancements. If the GUARANTOR fails to
perform any of the affirmative covenants contained in this Article or to
protect or preserve the COLLATERAL or the status and priority of the security
interest of the SECURED PARTIES in the COLLATERAL, and such failure shall

have notified the GUARANTOR thereof, the SECURED PARTIES may make advances to
perform the same on behalf of the GUARANTOR or to protect or preserve the
COLLATERAL or the status and priority of the security interest of the SECURED
PARTIES in the COLLATERAL, and all sums so advanced shall immediately upon
advance become secured by the security interest created by this AGREEMENT. The
contrary notwithstanding, the authorization contained in this Section shall
impose no duty or obligation on the SECURED PARTIES to perform any action or
make any advancement on behalf of the GUARANTOR and is for the sole benefit and
protection of the SECURED PARTIES.

Section 4.9. Documentation Of Collateral. The
GUARANTOR, upon the reasonable request of the ADMINISTRATIVE AGENT, shall
provide the ADMINISTRATIVE AGENT from time to time with: (a) written
statements or schedules identifying and describing the COLLATERAL, and all
additions, substitutions, and replacements thereof, in such detail as the
ADMINISTRATIVE AGENT may reasonably require; (b) copies of CUSTOMERS invoices
or billing statements; (c) evidence of shipment or delivery of goods or
merchandise to or performance of services for CUSTOMERS; and (d) such other
schedules and information as the ADMINISTRATIVE AGENT reasonably may require.
The items to be provided under this Section shall be in form satisfactory to
the ADMINISTRATIVE AGENT in its reasonable discretion and are to be executed
and delivered to the ADMINISTRATIVE AGENT from time to time solely for the
ADMINISTRATIVE AGENTS convenience in maintaining RECORDS of the COLLATERAL.
The GUARANTORS failure to give any of such items to the ADMINISTRATIVE AGENT
shall not affect, terminate, modify or otherwise limit the SECURED PARTIES
security interest in the COLLATERAL. The ADMINISTRATIVE AGENT shall have the
right, at any time and from time to time, to verify the GUARANTORS
RECEIVABLES, including during any continuing EVENT OF DEFAULT obtaining
verification of the RECEIVABLES directly from CUSTOMERS.

Section 4.10. Compliance With Laws. Except to the
extent described in Schedule 3.6 attached hereto, the GUARANTOR shall comply in
all material respects with all applicable LAWS, the noncompliance with which
would or could reasonably be expected to cause a MATERIAL ADVERSE EVENT,
including, but not limited to, all LAWS with respect to: (a) all restrictions,
specifications, or other requirements pertaining to products that it sells or
to the services it performs; (b) the conduct of its business; (c) the use,
maintenance, and operation of the real and personal properties owned or leased

circuit court of the State of Maryland selected by the SECURED PARTIES or in

counterclaim is mandatory, and not merely permissive, and will be considered
waived unless filed as a counterclaim in the action instituted by the SECURED
PARTIES. The GUARANTOR agrees that any forum other than the State of Maryland
is an inconvenient forum and that a suit brought by the GUARANTOR against the
SECURED PARTIES in a court of any state other than the State of Maryland should
be forthwith dismissed or transferred to a court located in the State of
Maryland by that court.

prepaid, addressed to the SECURED PARTIES or the GUARANTOR at the appropriate

LOAN AGREEMENT, will comply with each of the following covenants:

Section 12.1. No Transfers. The PLEDGOR will not
sell, convey, or otherwise dispose of any of the COLLATERAL or any interest
therein, or create, incur, or permit to exist any pledge, mortgage, lien,
charge, encumbrance or any security interest whatsoever in or with respect to
any of the COLLATERAL or the proceeds thereof, except as may be expressly
consented to by the SECURED PARTIES in writing.

Section 12.2. Warrant Title. The PLEDGOR will, at the
PLEDGORS sole expense, warrant and defend the right, title, special property
and security interests and pledges of the SECURED PARTIES in and to the

entity.

Section 12.3. No Additional Shares. The PLEDGOR will
not consent to or approve the issuance of any additional shares of any class of
capital stock in the CORPORATION or any securities convertible voluntarily by
the holder thereof or automatically upon the occurrence or non-occurrence of
any event or condition into, or exchangeable for, any such shares; or any

purchase or otherwise acquire any such shares.

PARTIES, copies of any written notices or other communications received by the

complete the security interests, pledges and liens of the SECURED PARTIES in
the COLLATERAL, it being the intention of the PLEDGOR to provide hereby a full
and absolute warranty of further assurance to the SECURED PARTIES.

Section 12.6. Cooperation With Enforcement Activities.
The PLEDGOR, upon the occurrence of an EVENT OF DEFAULT and the written
request therefor by the SECURED PARTIES, will promptly execute and deliver to
the SECURED PARTIES such documents, letters, or written representations as may
reasonably be requested by the SECURED PARTIES or any broker, from time to time
in order to accomplish the sale of all or any part of the COLLATERAL, including
but not limited to, all forms and documents required under any applicable LAWS.

Section 13. Waivers. No course of dealing between the
PLEDGOR and the SECURED PARTIES, nor any failure to exercise, nor any delay in
exercising, any right, power or privilege of the SECURED PARTIES hereunder or
under any other agreement between the PLEDGOR and the SECURED PARTIES, or under
any agreement between the SECURED PARTIES and the CORPORATION, shall operate as
a waiver of any term or condition of this PLEDGE AGREEMENT; nor shall any
single or partial exercise of any right, power or privilege hereunder or
thereunder preclude any other or further exercise thereof or the exercise of
any other right, power or privilege.

Section 14. Sale Of Collateral.

Section 14.1. Terms Of Sale. In addition to all other
rights and remedies available to the SECURED PARTIES pursuant to any other
agreements with the PLEDGOR or as otherwise provided by applicable LAWS, the
SECURED PARTIES, may upon the occurrence of an EVENT OF DEFAULT sell or
otherwise dispose of and deliver all or any portion of the COLLATERAL, in one
or more parcels, at public or private sale or sales, at any exchange, brokers
board or at any location selected by the SECURED PARTIES, at such prices and on
such terms as the SECURED PARTIES may deem best for cash or on credit, or for
future delivery without assumption of any credit risk. Any such sale shall be
in compliance with all applicable LAWS. Any purchaser of the COLLATERAL,
including the SECURED PARTIES, shall purchase the COLLATERAL in whole or in
part free of any right or equity of redemption in the PLEDGOR, which right or
equity is hereby expressly waived and released by the PLEDGOR, to the extent
permitted by applicable LAWS. The PLEDGOR acknowledges that the terms of sale
for the COLLATERAL may include: (a) a requirement that the COLLATERAL be sold
to only one individual purchaser for such purchasers own account and not as a
representative of any purchaser; (b) a requirement that any purchaser of all or
any part of the COLLATERAL represent in writing that such purchaser is
purchasing the shares constituting the COLLATERAL for investment purposes only
and without any intention to make a distribution thereof; (c) a requirement
that the certificates for any PLEDGED STOCK bear a legend to the effect that
the stock may not be resold without compliance with applicable federal and
state securities laws; and (d) a requirement that any purchaser of the
COLLATERAL make such representations and warranties to the SECURED PARTIES as
deemed necessary by the SECURED PARTIES.

Section 14.2. Delays In Sale; Private Sales. The
PLEDGOR acknowledges that it will be commercially reasonable for the SECURED
PARTIES to:(a) defer disposing of all or any portion of the COLLATERAL after an
EVENT OF DEFAULT has occurred for as long as the CORPORATION or the SECURED
PARTIES may require to comply with any requirements of applicable LAWS,
notwithstanding the fact that the value of the COLLATERAL may decline during
the time that disposition is deferred; and (b) sell all or any part of the
COLLATERAL at private sale, subject to investment letter or in any other manner
which will not require the COLLATERAL, or any part thereof, to be registered in
accordance with the Securities Act of 1933, as amended, or
the rules and regulations promulgated thereunder, or any other applicable LAW.
The PLEDGOR acknowledges that the SECURED PARTIES may, in the SECURED PARTIES
sole and absolute discretion,
approach a restricted number of potential purchasers and that a sale under
such circumstances may yield a lower price for the COLLATERAL or any portions
thereof than would otherwise be obtainable if the COLLATERAL were registered
and sold in the open market. The PLEDGOR acknowledges that a private sale of
the COLLATERAL would be a commercially reasonable sale.

Section 14.3. Application Of Proceeds Of Disposition.
The proceeds from any sale or from any other disposition of the COLLATERAL
shall be applied as follows:

a. First, to the costs and expenses incurred in
connection with the sale or disposition of the COLLATERAL, including but not
limited to all costs incurred in the care or safekeeping of the COLLATERAL,
reasonable attorneys fees, brokers commissions, appraisers fees and other
expenses incurred by the SECURED PARTIES;

b. Second, to the satisfaction of the OBLIGATIONS
regardless of when the amounts due upon the OBLIGATIONS mature and are due and
payable;

5

##### 



c. Third, to the payment of any other amounts or to
such other application as required by applicable LAWS or as required by the
decree, directive or injunction issued by a GOVERNMENTAL AUTHORITY; and

d. Fourth, to the PLEDGOR to the extent of any surplus
proceeds.

Section 14.4. Notice; Procedures Of Sale. The SECURED
PARTIES need not give more than ten (10) business days notice of the time and
place of any public sale or of the time after which a private sale of any or
all of the COLLATERAL may take place, which notice the PLEDGOR hereby agrees to
be commercially reasonable. The SECURED PARTIES shall be entitled to purchase
any or all of the COLLATERAL in any sale in the name or names of the SECURED
PARTIES, or in the name of any designee or nominee of the SECURED PARTIES. In
connection with any sale or transfer of any or all of the COLLATERAL, the
nominee of the SECURED PARTIES shall have the right to execute any document or
form, in the name of the SECURED PARTIES or in the name of the PLEDGOR, which
may be necessary or desirable in order to implement such sale, including
without limitation any forms required pursuant to Rule144
promulgated by the Securities And Exchange Commission. The PLEDGOR hereby
agrees to cooperate fully with the SECURED PARTIES in order to permit the
SECURED PARTIES to sell, at foreclosure or other private sale, any or all of
the COLLATERAL in compliance with all applicable LAWS.

Section 15. Remedies And Rights Cumulative. The rights
and remedies provided in this PLEDGE AGREEMENT and in the LOAN AGREEMENT or
otherwise provided by any other agreement between the PLEDGOR and the SECURED
PARTIES shall be cumulative, and the exercise of any particular right or remedy
shall not preclude the exercise of any other rights or remedies.

Section 16. Invalidity Of Any Part. If any provision
or part of any provision of this PLEDGE AGREEMENT shall for any reason be held
invalid, illegal, or unenforceable in any respect, such invalidity, illegality,
or unenforceability shall not affect any other provisions or the remaining part
of any effective provisions of this PLEDGE AGREEMENT, and this PLEDGE 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 of its
invalidity, illegality, or unenforceability.

Section 17. Amendment Or Waiver. This PLEDGE AGREEMENT
may be amended only by a writing duly executed by the PLEDGOR and by the
ADMINISTRATIVE AGENT with the consent of those other SECURED PARTIES as may be
required under the LOAN AGREEMENT. No waiver by the SECURED PARTIES of any of
the provisions of this PLEDGE AGREEMENT or of any of the rights or remedies of
the SECURED PARTIES with respect hereto shall be considered effective or
enforceable unless in writing.

Section 18. Fees And Expenses; Indemnification. The
PLEDGOR shall pay all fees, expenses, costs and charges, including reasonable
attorneys fees, which may be incurred by the SECURED PARTIES in connection
with enforcing any term or provision of this PLEDGE AGREEMENT. The PLEDGOR
shall indemnify and hold the SECURED PARTIES harmless from and against,
and reimburse the SECURED PARTIES with respect to, any and all loss, damage,
liability, cost or expense (including reasonable attorneys fees) incurred by
the SECURED PARTIES from time to time which in any manner relate or pertain to
this PLEDGE AGREEMENT and the actions and transactions contemplated herein.
The foregoing indemnification obligation shall include, but is not limited to,
indemnification of the SECURED PARTIES with respect to all claims brought
against the SECURED PARTIES based upon allegations that any prospectus,
memorandum or other disclosure document furnished to the purchaser of any of
the COLLATERAL contains any untrue or allegedly untrue statement of a material
fact which statement is derived from statements or representations made by the
PLEDGOR.

Section 19. Notices. Any notice required or permitted
by or in connection with this AGREEMENT shall be in writing and shall be made
by facsimile (confirmed on the date the facsimile is sent by one of the other
methods of giving notice provided for in this Section) or by hand delivery, by
Federal Express, or other similar overnight delivery service, or by certified
mail, unrestricted delivery, return receipt requested, postage prepaid,
addressed to the SECURED PARTIES or the PLEDGOR at the appropriate address set

request therefor by the SECURED PARTIES, will promptly execute and deliver to

reasonably be requested by the SECURED PARTIES or any broker, from time to time
in order to accomplish the sale of all or any part of the COLLATERAL, including
but not limited to, all forms and documents required under any applicable LAWS.

Section 13. Waivers. No course of dealing between the
PLEDGOR and the SECURED PARTIES, nor any failure to exercise, nor any delay in
exercising, any right, power or privilege of the SECURED PARTIES hereunder or
under any other agreement between the PLEDGOR and the SECURED PARTIES, or under
any agreement between the SECURED PARTIES and the CORPORATION, shall operate as
a waiver of any term or condition of this PLEDGE AGREEMENT; nor shall any
single or partial exercise of any right, power or privilege hereunder or
thereunder preclude any other or further exercise thereof or the exercise of
any other right, power or privilege.

Section 14. Sale Of Collateral.

Section 14.1. Terms Of Sale. In addition to all other
rights and remedies available to the SECURED PARTIES pursuant to any other
agreements with the PLEDGOR or as otherwise provided by applicable LAWS, the
SECURED PARTIES, may upon the occurrence of an EVENT OF DEFAULT sell or
otherwise dispose of and deliver all or any portion of the COLLATERAL, in one
or more parcels, at public or private sale or sales, at any exchange, brokers
board or at any location selected by the SECURED PARTIES, at such prices and on
such terms as the SECURED PARTIES may deem best for cash or on credit, or for
future delivery without assumption of any credit risk. Any such sale shall be
in compliance with all applicable LAWS. Any purchaser of the COLLATERAL,
including the SECURED PARTIES, shall purchase the COLLATERAL in whole or in
part free of any right or equity of redemption in the PLEDGOR, which right or
equity is hereby expressly waived and released by the PLEDGOR, to the extent
permitted by applicable LAWS. The PLEDGOR acknowledges that the terms of sale
for the COLLATERAL may include: (a) a requirement that the COLLATERAL be sold
to only one individual purchaser for such purchasers own account and not as a
representative of any purchaser; (b) a requirement that any purchaser of all or
any part of the COLLATERAL represent in writing that such purchaser is
purchasing the shares constituting the COLLATERAL for investment purposes only
and without any intention to make a distribution thereof; (c) a requirement
that the certificates for any PLEDGED STOCK bear a legend to the effect that
the stock may not be resold without compliance with applicable federal and
state securities laws; and (d) a requirement that any purchaser of the
COLLATERAL make such representations and warranties to the SECURED PARTIES as
deemed necessary by the SECURED PARTIES.

Section 14.2. Delays In Sale; Private Sales. The
PLEDGOR acknowledges that it will be commercially reasonable for the SECURED
PARTIES to:(a) defer disposing of all or any portion of the COLLATERAL after an
EVENT OF DEFAULT has occurred for as long as the CORPORATION or the SECURED
PARTIES may require to comply with any requirements of applicable LAWS,
notwithstanding the fact that the value of the COLLATERAL may decline during
the time that disposition is deferred; and (b) sell all or any part of the
COLLATERAL at private sale, subject to investment letter or in any other manner
which will not require the COLLATERAL, or any part thereof, to be registered in
accordance with the Securities Act of 1933, as amended, or
the rules and regulations promulgated thereunder, or any other applicable LAW.
The PLEDGOR acknowledges that the SECURED PARTIES may, in the SECURED PARTIES
sole and absolute discretion, approach a restricted number of potential
purchasers and that a sale under such circumstances may yield a lower price for
the COLLATERAL or any portions thereof than would otherwise be obtainable if
the COLLATERAL were registered and sold in the open market. The PLEDGOR
acknowledges that a private sale of the COLLATERAL would be a commercially
reasonable sale.

Section 14.3. Application Of Proceeds Of Disposition.
The proceeds from any sale or from any other disposition of the COLLATERAL
shall be applied as follows:

a. First, to the costs and expenses incurred in
connection with the sale or disposition of the COLLATERAL, including but not
limited to all costs incurred in the care or safekeeping of the COLLATERAL,
reasonable attorneys fees, brokers commissions, appraisers fees and other
expenses incurred by the SECURED PARTIES;

b. Second, to the satisfaction of the OBLIGATIONS
regardless of when the amounts due upon the OBLIGATIONS mature and are due and
payable;

such other application as required by applicable LAWS or as required by the
decree, directive or injunction issued by a GOVERNMENTAL AUTHORITY; and

proceeds.

PARTIES need not give more than ten (10) business days notice of the time and
place of any public sale or of the time after which a private sale of any or
all of the COLLATERAL may take place, which notice the PLEDGOR hereby agrees to
be commercially reasonable. The SECURED PARTIES shall be entitled to purchase
any or all of the COLLATERAL in any sale in the name or names of the SECURED
PARTIES, or in the name of any designee or nominee of the SECURED PARTIES. In
connection with any sale or transfer of any or all of the COLLATERAL, the
nominee of the SECURED PARTIES shall have the right to execute any document or
form, in the name of the SECURED PARTIES or in the name of the PLEDGOR, which
may be necessary or desirable in order to implement such sale, including
without limitation any forms required pursuant to Rule144
promulgated by the Securities And Exchange Commission. The PLEDGOR hereby
agrees to cooperate fully with the SECURED PARTIES in order to permit the
SECURED PARTIES to sell, at foreclosure or other private sale, any or all of
the COLLATERAL in compliance with all applicable LAWS.

Section 15. Remedies And Rights Cumulative. The rights
and remedies provided in this PLEDGE AGREEMENT and in the LOAN AGREEMENT or
otherwise provided by any other agreement between the PLEDGOR and the SECURED
PARTIES shall be cumulative, and the exercise of any particular right or remedy
shall not preclude the exercise of any other rights or remedies.

Section 16. Invalidity Of Any Part. If any provision
or part of any provision of this PLEDGE AGREEMENT shall for any reason be held
invalid, illegal, or unenforceable in any respect, such invalidity, illegality,
or unenforceability shall not affect any other provisions or the remaining part
of any effective provisions of this PLEDGE AGREEMENT, and this PLEDGE 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 of its
invalidity, illegality, or unenforceability.

Section 17. Amendment Or Waiver. This PLEDGE AGREEMENT
may be amended only by a writing duly executed by the PLEDGOR and by the
ADMINISTRATIVE AGENT with the consent of those other SECURED PARTIES as may be
required under the LOAN AGREEMENT. No waiver by the SECURED PARTIES of any of
the provisions of this PLEDGE AGREEMENT or of any of the rights or remedies of
the SECURED PARTIES with respect hereto shall be considered effective or
enforceable unless in writing.

Section 18. Fees And Expenses; Indemnification. The
PLEDGOR shall pay all fees, expenses, costs and charges, including reasonable
attorneys fees, which may be incurred by the SECURED PARTIES in connection
with enforcing any term or provision of this PLEDGE AGREEMENT. The PLEDGOR
shall indemnify and hold the SECURED PARTIES harmless from and against, and
reimburse the SECURED PARTIES with respect to, any and all loss, damage,
liability, cost or expense (including reasonable attorneys fees) incurred by
the SECURED PARTIES from time to time which in any manner relate or pertain to
this PLEDGE AGREEMENT and the actions and transactions contemplated herein.
The foregoing indemnification obligation
shall include, but is not limited to, indemnification of the SECURED
PARTIES with respect to all claims brought against the SECURED PARTIES based
upon allegations that any prospectus, memorandum or other disclosure document
furnished to the purchaser of any of the COLLATERAL contains any untrue or
allegedly untrue statement of a material fact which statement is derived from
statements or representations made by the PLEDGOR.

Section 19. Notices. Any notice required or permitted
by or in connection with this AGREEMENT shall be in writing and shall be made
