ARTICLE 2 - THE CREDIT LINE; LETTERS OF CREDIT; HEDGES

Section 2.1. Credit Line.

2.1.1 Loans. Upon request of the Borrower from time to time during the
period from and including the Closing Date until the Termination Date or any
earlier date on which the Credit Line shall be terminated in accordance with
this Agreement, subject to the terms and conditions set forth herein (including
the conditions precedent set forth in Section 2.10), the Lender shall make
loans or advances to the Borrower from time to time (each such loan or advance
is referred to herein as a Loan) in an aggregate principal amount of up to
$10,000,000 outstanding at any one time; provided, however that in no event
shall the Lender have any obligation to make any Loan if, after giving effect
thereto, the Outstanding Credit Amount shall exceed the lesser of (i) the
Borrowing Base then in effect and (ii) the Maximum Credit Amount. Without
limiting any other provision of this Agreement, the Lender is hereby
irrevocably and unconditionally authorized, upon any drawing under any Letter
of Credit not otherwise immediately reimbursed by the Borrower, to make a Loan
to the Borrower in the amount of such drawing and apply the proceeds of such
Loan directly to the Reimbursement Obligation owing in respect of such drawing;
in the event that the conditions for the making of a Loan hereunder are not
then satisfied, the Lender shall nonetheless have the right, but not the
obligation, to make any such Loan for such purpose.

2.1.2 Use of Proceeds of Loans. The Borrower shall use the proceeds of
the Loans solely for the Borrowers general corporate purposes.

2.1.3 Repayment of Principal of Loans; Mandatory Prepayment . All amounts
outstanding under the Loans, including the principal thereof, all accrued
unpaid interest thereon and any and all applicable fees, charges and other
amounts owing by the Borrower under this Agreement, shall be absolutely due and
payable on the Termination Date or any earlier date on which the Credit Line is
terminated in accordance with this Agreement. In addition, on any date on
which the Outstanding Credit Amount exceeds the lesser of (i) the Maximum
Credit Amount and (ii) the Borrowing Base then in effect, the Borrower shall
make a mandatory prepayment of Loans in a principal amount equal to such
excess.

2.1.4 Letters of Credit. From time to time until the Termination Date,
the Borrower may request, and the Lender, upon any such request but subject to
the terms and conditions set forth herein, shall provide, standby or commercial
Letters of Credit for the account of the Borrower in amounts up to the limits

set forth in this part and otherwise in accordance with the terms and
conditions set forth in this part and subject to the further conditions
precedent set forth in Section 2.10 hereof:

(a) Limitation on Amount of Letters of Credit. Each Letter of Credit
shall be issued in the amount specified by the Borrower in the LC Application
(defined below) therefor submitted by the Borrower; provided, that (i) no
Letter of Credit shall be
issued in an amount which would cause the aggregate amount of the LC
Obligations to exceed the Letter of Credit Sublimit, and (ii) no Letter of
Credit shall be issued in an amount which would cause the Outstanding Credit
Amount, after giving effect to the requested Letter of Credit, to exceed the
Maximum Credit Amount.

(b) Term. Unless otherwise specifically and in writing agreed by the
Lender, no Letter of Credit shall have a term in excess of 12 months, and no
Letter of Credit shall be renewed or extended unless the conditions precedent
to issuance of Letters of Credit are satisfied with respect to such Letter of
Credit, as renewed.

(c) LC Application. Without limiting any other conditions to the Lenders
agreement to issue any Letter of Credit hereunder, the Lender shall have no
obligation to issue any Letter of Credit except upon the delivery by the
Borrower of an Application for Letter of Credit with respect thereto in form
and substance satisfactory to the Lender, with all applicable information
completed in accordance with terms approved by the Lender, executed by the
Borrower (each such Application for Letter of Credit is referred to herein as
an LC Application; LC Application shall include each Application for Letter
of Credit made with respect to those Letters of Credit issued before the
execution and delivery of this Agreement). Each Letter of Credit issued shall
be in a form satisfactory to the Lender and the terms and conditions thereof
shall be as indicated in the applicable LC Application and any other
documentation executed by the Borrower and delivered to and approved by the
Lender in connection with the issuance of such Letter of Credit. Without
limiting any obligations of the Borrower set forth in any LC Application, the
Borrower hereby promises to pay to the Lender, upon demand, the full amount of
all Reimbursement Obligations not otherwise paid with the proceeds of a Loan
made pursuant to subsection 2.1.1 hereof, together with interest thereon until
paid in full at the floating annual rate equal to the Default Rate obtained
from time to time, unless a different rate is specified in the applicable LC
Application. The Borrower hereby waives presentment, notice of dishonor and
protest with respect to each amount which becomes owing by the Borrower to the
Lender in connection with any Letter of Credit.

(d) Letter of Credit Fees. Upon the issuance (and each renewal or
extension, as applicable) of each Letter of Credit, the Lender shall have
earned a non-refundable Letter of Credit fee, calculated on an annual basis
(using a 360-day year applied to the actual number of calendar days to elapse
in the applicable period) for the period beginning on and including the date of
issuance thereof (and each date of extension, as applicable) and ending on and
including the expiration date thereof, in an amount obtained by applying the
Letter of Credit Fee Rate to the Stated Amount of the Letter of Credit as of
such date of issuance (or renewal or extension, as the case may be). The
Letter of Credit Fee Rate is (i) 1.25% per annum, except as may otherwise be
agreed in writing by the lender and the Borrower with respect to any Letter of
Credit. The Letter of Credit fees shall be payable by the Borrower, with
respect to each Letter of Credit, in advance on each issuance, renewal or
extension date.

(e) Payment Obligations Unconditional. The payment obligations of the
Borrower under this subsection 2.1.4 shall be unconditional and irrevocable and
shall be paid strictly in accordance with this Agreement and the applicable LC
Applications regardless of the circumstances. Without limiting the

foregoing,
none of the following circumstances shall reduce, discharge, stay, defer or
impair in any other manner the payment obligations of the Borrowers under this
part:

(i) any lack of validity or enforceability of any Letter of Credit, any LC
Application, this Agreement or any related document;

(ii) any amendment, waiver, release or termination of or any consent to
departure from the terms of any Letter of Credit, any LC Application, this
Agreement or any related document;

(iii) any extension of time or other modification or the terms and
conditions governing the making and honoring of any drawing, or any extension
of time or other modification of the terms and conditions for any other act to
be performed under the terms of any Letter of Credit;

(iv) the existence of any claim, set-off, defense or other right which any
Borrower may have at any time against any beneficiary under, or any transferee
of, any Letter of Credit (or any person for whom any such beneficiary or
transferee may hold
a Letter of Credit or any interest therein), or the Lender or any other
person, regardless of whether such claim, set-off, defense or other right is
held or asserted in connection with this Agreement or any unrelated
transaction;

(v) the surrender or impairment of any security for the Obligations;

(vi) any demand, draft, certification, statement or any other document
presented under any Letter of Credit being forged or otherwise fraudulent,
invalid or insufficient in any respect or any statement therein being untrue or
inaccurate in any respect;

(vii) payment by the Lender under any Letter of Credit against
presentation of a draft, certificate or other documentation which does not
comply with the terms of such Letter of Credit, except to the extent that such
payment constitutes gross negligence or willful misconduct of the Lender; or

(viii) any other circumstance or occurrence whatsoever, whether or not
similar to any of the foregoing, except to the extent resulting principally
from the gross negligence or willful misconduct of the Lender.

(f) Subrogation to and Assignment of Beneficiarys Rights. In each
instance in which the Lender honors any drawing under any Letter of Credit, the
Lender shall be subrogated to all of the rights of the beneficiary and all of
the rights of any other person having any beneficial interest in the amounts
drawn under such Letter of Credit (whether held against the Borrower or any
other person or against any monies or property) and, immediately upon payment
to such person of amounts drawn under such Letter of Credit, the Lender shall
be entitled to an assignment of such rights, in form and substance satisfactory
to the Lender. Such rights of subrogation shall be in addition to all other
rights of the Lender under this Agreement, the related loan documents and
applicable law. The Borrower shall have the obligation to do all things and
take all such action, at the Borrowers sole expense, as may be required from
time to time to confirm or establish the Lenders right of subrogation, as
aforesaid.

(g) Issuance of Letters of Credit Subject to Applicable Law. The Lender
shall have no obligation to issue any Letter of Credit if, in the Lenders good
faith determination, such issuance (i) would violate any applicable law or any
other guideline or directive (whether or not having the force of law)

-14-

##### 



issued by
any governmental authority having supervisory or other regulatory authority
over the Lender, if it is the Lenders usual practice to comply with guidelines
or directives issued by such governmental authority, or (ii) would subject the
Lender to any cost or to any reduction in the amounts or rate of return to be
received by the Lender with respect to the Credit Line (other than costs or
reductions which would be applicable under the laws, guidelines and directives
applicable to the Lender or Letters of Credit issued hereunder and in effect on
the Effective Date) unless the Lender shall have received from the Borrower an
amount deemed by the Lender to be sufficient to fully compensate the Lender for
any such cost or reduction in amounts or rate of return to be received by the
Lender.

2.1.5 Hedges . From time to time, the Borrower may request, and the
Lender, upon any such request but subject to the terms and conditions set forth
herein, and also in the Lenders sole and absolute discretion, may enter into
any Hedge with the Borrower upon terms and conditions mutually satisfactory to
the Lender and the Borrower. Without limiting the Lenders discretion in any
such matter, the parties anticipate that no Hedge will be made which shall
cause the Hedge Exposure Amount to exceed $1,000,000.

2.1.6 Deposit of Cash Collateral For LC Obligations and Hedge Exposure
Amount Upon Termination of Credit Line. If, on or after the Termination Date
or on any other date on which the Credit Line is otherwise terminated in
accordance with this Agreement, any Letter of Credit remains outstanding or any
Hedge remains in effect, the Borrower shall, without demand or the taking of
any other action by the Lender, deposit with the Lender, in Dollars and in
immediately available funds, the amount which is equal to the sum of (i) 101%
of the aggregate of the Stated Amounts of such Letters of Credit, plus (ii) the
Hedge Exposure Amount (the sum of (i) and (ii) as of any applicable
determination date on or after the termination of the Credit Line shall be
referred to as the Cash Collateral Requirement), which funds shall be held by
the Lender in a restricted collateral account maintained by the Lender in its
own name, for the purpose of providing the Lender security for and a source for
reimbursement for drawings and acceptances paid under such Letters of Credit
and security for the payment to the Lender of amounts payable by the Borrower
to the Lender under such Hedges (the amount on deposit in the aforesaid
restricted collateral account from time to time shall be referred to herein as
the Cash Collateral Balance). From time to time,
upon the expiration or surrender of any such outstanding Letter of Credit
or the termination of such Hedge(s), after receiving payment of the
Reimbursement Obligations in respect of such Letters of Credit and, if any, the
accrued unpaid interest thereon, and, as applicable, amounts payable to the
Lender in connection with the termination of such Hedge(s), the Lender shall
promptly remit to the Borrower, from the remaining balance of such collateral
account, the amount equal to the excess of the Cash Collateral Balance over the
Cash Collateral Requirement, provided that no Event of Default shall have
occurred and be continuing. The aforesaid collateral account shall be an
interest bearing account of a type then generally offered by the Lender in the
ordinary course of its business as a depository institution and shall be
mutually satisfactory to the Lender and the Borrower, provided that if such
account is a time deposit account, the term or terms for which the rate or
rates applicable to such account is fixed shall end on or before the expiration
date(s) of the Letter(s) of Credit in respect of which such account is
established. Upon any drawing on any of such Letters of Credit or upon any
amount becoming due and payable to the Lender under any Hedge, the Lender shall
be, and hereby irrevocably is, authorized to apply the amounts in such
collateral account against the obligation becoming due in connection with such
drawing or such Hedge, as the case may be; provided, however, that prior to
such application, the amounts contained in the applicable collateral account
shall be applied to pay any applicable early withdrawal fees, breakage costs or
similar charges incurred upon the liquidation of such collateral account. The
amount of any deposit required pursuant to this Section shall be considered to
constitute a principal obligation then due and payable for purposes of
determining the amount owing by Borrower

hereunder, including any such
determination made in connection with an action brought to enforce the payment
of the Obligations.

Section 2.2 Interest on the Loans. Interest on the Loans shall accrue on
the outstanding principal balance of each Loan at a floating and fluctuating
per annum rate which for each day shall be equal to the rate obtained by adding
the Applicable Margin then in effect to the Prime Rate then in effect;
provided, that for each day on which any Event of Default has occurred and is
continuing, the applicable interest rate shall be the Default Rate in effect
for such day. All computations of interest payable under this Agreement and
the Note shall be made on the basis of a three hundred sixty (360) day year,
for actual days elapsed. Interest shall continue to accrue on each Loan as
provided herein until full payment thereof. Interest on each outstanding Loan
shall be due and payable on each of the following dates: (i) on the first day
of each calendar month until the earlier of the Termination Date or the full
repayment of such Loan, (ii) on the Termination Date and on any other date on
which the principal of such Loan becomes due and payable (whether by
acceleration or otherwise), and (iii) after the Termination Date or any other
date on which the principal of such Loan becomes due and payable, upon demand
until all Obligations are paid in full. Interest accrued upon the Loans and
the Reimbursement Obligations shall be computed on outstanding balances as
reflected on the Lenders books and records.

Section 2.3 Note. The Borrower shall execute and deliver to the Lender
the Borrowers Revolving Credit Note made to the order of the Lender in the
stated principal amount of $10,000,000.00, in substantially the form of Exhibit
A attached hereto (as the same may be extended, renewed, or otherwise modified
or replaced from time to time, the Note), which instrument shall evidence the
Borrowers obligation to pay to the Lender all amounts outstanding from time to
time under the Loans, including principal, interest, charges and fees. The
date and amounts of each Loan made by the Lender and each payment made by the
Borrower shall be recorded by the Lender on the books and records of the
Lender, but any failure to record such dates or amounts shall not relieve the
Borrower of its duties and obligations under the Loan Documents.

Section 2.4 Optional Prepayment. The Borrower may make optional
prepayments of the Loans from time to time, without penalty or premium.
Amounts prepaid may be readvanced subject to the terms and conditions of this
Agreement.

Section 2.5 Commitment Fee. On the Closing Date, the Borrower shall have
paid to the Lender the full amount of the commitment fee described in the
commitment letter dated January 23, 2003 issued by the Lender to the Borrower,
in the amount of $20,000, which shall be non-refundable. Such commitment fee
has been fully earned by the Lender.

Section 2.6 Reinstatement of Avoided Payments. If any amount received by
the Lender on account of the Obligations is required to be returned or paid to
any Borrower or any other person pursuant to any insolvency or bankruptcy law
or for any other reason (each such amount, together with any interest required
to be paid by the Lender thereon, is referred to as an Avoided Payment), then
as of the date the Lender makes such return or other payment, (i) the
Borrowers agreements and obligations under the Loan Documents shall be
reinstated, (ii) the amount of the Avoided Payment shall be reinstated as
principal bearing interest at the Default Rate, and all such amounts
shall be immediately due and payable (without presentment, demand, notice

applicable thereto or release the obligor thereon. The Lender is authorized
and empowered to accept the return of the goods represented by any of the
Receivables, without notice to or consent by the Borrower, all without
discharging or in any way affecting the liability of the Borrower under the

(o) The indictment of any Borrower or Guarantor for a felony under any

(p) The issuance of any injunction against the Borrower which enjoins or

Borrowers business affairs; or

(q) any breach or violation by the Borrower of any covenant or other
agreement of the Borrower under this Agreement other than those addressed by
the preceding paragraphs of this Section 7.1, and the failure of the Borrower
to cure such breach or violation within 30 days after written notice thereof to
the Borrower.

Section 7.2. Certain Default Remedies. In addition to all other rights
and remedies provided by law and the Loan Documents, upon the occurrence of any
Event of Default, the Lender may: (a) terminate the Credit Line; (b)
accelerate and call immediately due and payable all or any part of the
Obligations; (c) seek specific performance or injunctive relief to enforce
performance of the undertakings, duties, and agreements provided in the Loan
Documents, whether or not a remedy at law exists or is adequate; and (d)
exercise any rights of a secured creditor under the Uniform Commercial Code, as
adopted and amended in Maryland, 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
Lender may specify.

Section 7.3. Automatic Acceleration. Upon the occurrence of an Event of
Default as described in Sections 7.1(i) or 7.1(j) 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 Lender.

Section 7.4. Sale Of Collateral. In addition to any other remedy provided
herein, upon the occurrence of an Event of Default, the Lender, 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
Lender 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 Lender 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 is 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
shall be commercially reasonable notice of such sale or other disposition. The
Borrower shall assemble, or shall cause to be assembled, at the Borrowers own
expense, the Collateral at such place or places as the Lender shall designate.
At any such sale or other disposition, the Lender may, to the extent

-35-





---



##### 



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 Lender under this Section, the Lender 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 Lender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 as the Lender may determine in the Lenders discretion.

Section 7.5 Confession of Judgment. Upon the occurrence of an Event of
Default, the Borrower authorizes any attorney admitted to practice before any
court of record in the United States to appear on behalf of the Borrower 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 Borrower without
prior notice or opportunity of the Borrower for prior hearing, in favor of the
Lender in an amount equal to the sum of the full amount of the Obligations then
outstanding (including the principal of and interest on the Loans and the
Reimbursement Obligations and all fees, costs, charges and other amounts owing
under the Loan Documents), plus attorneys fees equal to the amount equal to
15% of the sum of the amounts described in clauses (a) and (b) of this
sentence, plus court costs. The Borrower consents to the jurisdiction of the
Circuit Court for Baltimore City, Maryland or any County in the State of
Maryland, as selected by the Lender, or of the United States District Court for
the District of Maryland in the event there is a basis for federal subject
matter jurisdiction, and consents that venue and jurisdiction shall be proper
in any of the aforesaid Circuit Courts selected by the Lender or in the United
States District Court for the District of Maryland. The Borrower waives the
benefit of any and every statute, ordinance, or rule of court which may be
lawfully waived conferring upon the Borrower 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 Borrower 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 Lender shall deem necessary or
advisable.

In the event that the Lender receives, as a result of execution on a
judgment confessed hereunder, amounts in respect of attorneys fees which
exceed the actual attorneys fees incurred by the Lender in connection with the
Obligations and the Loan Documents, then, upon full and final payment of all of
the other obligations of the Borrower to the Lender, the Lender shall remit
such excess to the Borrower.

Section 7.6. Remedies Cumulative. The rights and remedies provided in
this Agreement and in the other Loan 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.

ARTICLE 8 - GENERAL CONDITIONS AND TERMS

Section 8.1. 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 the Lender. 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 such time as the Obligations have been fully paid and performed, the
Borrower shall not: (a) suspend or discontinue any payments required by the
Loan Documents; and (b) fail to perform and observe all of the Borrowers
covenants and agreements set forth in the Loan Documents.

Section 8.2. Indemnity. The Borrower agrees to defend, indemnify and hold

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 Lender
or an affiliated entity is a party thereto) and the prosecution and defense
thereof, arising out of or in any way connected with any Loan 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 Lender, an entity affiliated with the
Lender, or any of their respective employees, agents, officers or directors.
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

forth herein.

Section 8.6. Waivers. The Lender at any time or from time to time may
waive all or any rights under this Agreement or any other Loan Document, but
any waiver or indulgence by the Lender at any time or from time to time shall
not constitute a future waiver of performance or exact performance by the
Borrower.

Section 8.7. Continuing Obligation Of Borrower. The terms, conditions,
and covenants set forth herein and in the Loan Documents shall survive Closing
and shall constitute a continuing obligation of the Borrower during the course
of the transactions contemplated herein. The security interests, 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. At any time that the Obligations have been paid in full and no
Hedge or Letter of Credit remains in effect, the Borrower may terminate this
Agreement and the Lender shall provide, at the Borrowers expense,
documentation sufficient to release all liens and security interests of the Lender in the Collateral;
provided, that the foregoing provisions of this Section shall be subject to
Section 2.6 hereof.

Section 8.8. Choice Of Law. The laws of the State of Maryland (excluding,
however, conflict of law principles) shall govern and be applied to determine

Section 8.9.3. Waiver Of Objections To Venue. Waives any right to object
to the maintenance of any suit in any of the courts specified in Section 8.9.2

REVOLVING CREDIT NOTE

THIS REVOLVING CREDIT NOTE (this Note) is made this      day of
February, 2003, by MARTEK BIOSCIENCES CORPORATION and MARTEK BIOSCIENCES
BOULDER CORPORATION (collectively, the Borrower; provided, that where the
context so requires, the term Borrower shall mean either of such persons) to
and for the benefit of ALLFIRST BANK (the Lender), and the Lenders
successors and assigns (including each subsequent holder of this Note). This
Note is the Note under the Loan and Security Agreement of even date herewith
by and between the Borrower and the Lender (as amended, supplemented, replaced
or otherwise modified from time to time, collectively, the Loan Agreement)
and evidences the Loans made from time to time pursuant to such Loan Agreement.
Capitalized terms used herein but not otherwise defined herein shall have the
respective meanings given in the Loan Agreement, except in any instance in
which the context clearly requires otherwise. The rules of construction set
forth in Section 1.2 of the Loan Agreement shall be applicable to this Note, as
if set forth in full herein.

FOR VALUE RECEIVED, the undersigned Borrower hereby promises (jointly and
severally as to each Borrower) to pay to the order of the Lender, and the
Lenders successors and assigns (including each subsequent holder of this
Note), at the office of the Lender at 25 South Charles Street, Baltimore,
Maryland 21201 (or at such other address as the holder of this Note may
specify from time to time by written notice to the Borrower), on the
Termination Date specified in the Loan Agreement (including any extension
thereof), the principal sum of TEN MILLION DOLLARS ($10,000,000.00) or so much
thereof as shall be outstanding on account of the principal of the Loans,
together with interest on the unpaid principal balance hereof outstanding from
time to time at the rate or rates hereafter specified until paid in full, and
all other sums owing by the Borrower to the holder under this Note and under
the other Loan Documents.

1.     Interest Rate; Calculation of Interest; Payment of Interest. Interest
on the unpaid principal balance hereof shall be due and payable and calculated

in accordance with the provisions of Section 2.2 of the Loan Agreement
[captioned Interest on the Loans]. Interest shall accrue at the annual
interest rate or rates specified in Section 2.2 of the Loan Agreement until
this Note is fully paid, notwithstanding entry of judgment on this Note.
Without limiting the provisions of Section 2 below, interest payments shall be
made at the times and in the amounts provided in subsection 2.2 of the Loan
Agreement, at the place for payment provided above in this Note.

2.     Full Payment on Termination Date; Revolving Credit. All amounts
outstanding on this Note, including all unpaid principal, accrued unpaid
interest, charges and fees, are due and payable in full on the Termination Date
specified in the Loan Agreement. Principal amounts hereunder may be paid or
prepaid without penalty or premium and, until the Termination Date and to the
extent provided in the Loan Agreement, readvanced from time to time.

3.     Late Payment Charge. If any monthly interest payment hereunder is not
received by the holder within 15 days after its due date, the Borrower shall
pay to the holder hereof a late payment charge in an amount
equal to 5% of the amount then due and payable. The late payment charge
shall be due whether or not the holder exercises any right of the holder to
accelerate the maturity hereof or any other default remedy. The existence of
the right by the holder to receive a late payment charge shall not constitute a
grace period or provide any right in the Borrower to make any payment other
than on its due date.

##### 



4.     Application of Payments. All payments made hereunder shall be applied
first to late payment charges and reimbursement for collection expenses, if
any, which are then due, next to accrued unpaid interest, and then to
principal, or in such other order or proportion as the holder, in the holders
sole discretion, may elect from time to time.

5.     Default; Acceleration; Confession of Judgment. Upon any failure by
the Borrower to pay any amount evidenced by this Note when and as the same
becomes due, which is not cured within any grace or cure period made applicable
pursuant to the Loan Agreement, or upon the occurrence of any other Event of
Default under the Loan Agreement or any of the other Loan Documents, the entire
unpaid principal balance of this Note, together with all accrued unpaid
interest hereunder and all other amounts due hereunder, shall, at the option of
the holder, become due and payable in full; and, in addition to all other
rights or remedies available to the holder under the Loan Documents or under
applicable law, the Borrower authorizes any attorney admitted to practice
before any court of record in the United States to appear on behalf of the
Borrower 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
Borrower, without prior notice or opportunity of the Borrower for prior
hearing, in favor of the holder of this Promissory Note in the full amount
outstanding under this Note (including principal, accrued interest and any and
all penalties, fees and costs) plus attorneys fees equal to fifteen percent
(15%) of the amount outstanding hereunder plus court costs. The Borrower
agrees and consents that venue and jurisdiction shall be proper in the Circuit
Court of any County of the State of Maryland or of Baltimore City, Maryland, or
in the United States District Court for the District of Maryland. The Borrower
waives the benefit of any and every statute, ordinance, or rule of court which
may be lawfully waived conferring upon any Borrower 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 Borrower 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 holder shall deem necessary or
advisable.

In the event that the Lender receives, as a result of execution on a
judgment confessed hereunder, amounts in respect of attorneys fees which
exceed the actual attorneys fees incurred by the Lender in connection with the
Obligations and the Loan Documents, then, upon full and final payment of all of
the other obligations of the Borrower to the Lender, the Lender shall remit
such excess to the Borrower.

6.     Costs of Enforcement. The Borrower shall pay all of the holders
reasonable costs, fees (including, without limitation, reasonable attorneys
fees) and expenses incurred in connection with the holders enforcement or
collection of this Note.

7.     Negotiable Instrument. The Borrower agrees that each holder of this
Note shall have, with respect to this Note, all rights of a holder of a
negotiable instrument, even if, absent this paragraph, this Note would not be
considered a negotiable instrument under applicable law. If the holder hereof
would qualify as a holder in due course with respect to this Note, assuming
that this Note is a negotiable instrument, then the holder shall have all
rights of a holder in due course with respect to this Note.

8.     Notices. Any notice or demand required or permitted by or in
connection with this Note shall be given in the manner specified in the Loan
Agreement for the giving of notices under the Loan Agreement; provided, that
each notice or demand actually received in writing by the Borrower shall be
effective even if the manner of delivery is other than as provided in the Loan
Agreement.

and each other person executing this Note or otherwise assuming liability for
the payment hereof, whether as maker, co-maker, endorser or guarantor.

10.     Manner and Method of Payment. All payments called for in this
Promissory Note shall be made in lawful money of the United States of America.
If any payment is made by check, draft, or other payment instrument, such
check, draft, or other payment instrument shall represent immediately available
funds. In the holders sole discretion, any payment made by a check, draft, or
other payment instrument shall not be considered to have been made until such
time as the funds represented thereby have been collected by the holder. If
the due date of any payment falls on a day which is not a Business Day, the
Borrower shall make such payment on the immediately succeeding Business Day.

11.     Unconditional Obligation. The payment of this Note shall be the
absolute and unconditional 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 the holder, and the Borrower shall pay
absolutely, when and as due, all amounts which from time to time are
outstanding hereunder, free of any deductions and without abatement, diminution
or set-off.

12.     Waivers; Consent to Extension. Each Person executing this Note as
Borrower and each other Person which becomes a maker, co-maker, endorser,
guarantor or other co-obligor on this Note hereby (a) waive demand,
presentation, protest, notice of default; and (b) agree that the maturity of
this Note, or any payment due hereunder, may be extended at any time or from
time to time by the holder of this Note without releasing, discharging, or
otherwise affecting the liability of such party.

13.     Assignable by Lender. This Note may be assigned by the Lender (or any
other holder hereof), in whole or in part, at any time and from time to time.

14.     Successors and Assigns. This Note shall be binding upon the
successors and assigns of the Borrower and shall inure to the benefit of the
successors and assigns of the Lender (including each subsequent holder hereof).

15.     Applicable Law. This Note and the other Loan Documents shall be
governed by and construed in accordance with the laws of the State of Maryland,
without regard to the conflicts of law principles.

16.     Severability. If any provision or part of any provision of this Note
shall for any reason be held invalid, illegal or unenforceable in any respect,
such invalidity, illegality or unenforceability shall not affect any other
provisions of this Note and this Note 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.

17.     Venue; Jurisdiction. The provisions of Section 8.9 of the Loan
Agreement (captioned Submission To Jurisdiction; Venue; Actions Against
Lender) are hereby incorporated into this Note by reference and made a part
hereof as if set forth in full herein.

with respect to this Note or any other Loan Document or which in any way
relates, directly or indirectly, to the Loan or any event, transaction, or
occurrence arising out of or in any way connected with the Loan, or the
dealings of the parties with respect thereto, shall be tried only by a court
and not by a jury. EACH PARTY HEREBY EXPRESSLY WAIVES ANY RIGHT TO A TRIAL BY
JURY IN ANY SUCH SUIT, ACTION, OR PROCEEDING. This Section is a specific and
material aspect of the agreement among the parties.
