                                    RECITALS

     The BORROWER has requested certain credit accommodations from the LENDER.
The LENDER has agreed to provide the requested credit accommodations to the
BORROWER, but only if the GUARANTOR provides to the LENDER the guaranties of
payment and performance set forth in this GUARANTY. The GUARANTOR is willing to
provide this GUARANTY to the LENDER in order to induce the LENDER to provide the
requested credit accommodations to the BORROWER.

     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 LENDER the following
guaranties and indemnifications.

     Section 1. Guaranty. The GUARANTOR guarantees: (a) the payment of any and
all sums now or hereafter due and owing to the LENDER 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 LENDER from time to time, arising out of or related to any
credit accommodation, loan, letter of credit, guaranty, depository relationship,
transaction, event, or occurrence, 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 all renewals, refinancings, extensions, substitutions,
amendments, and modifications thereof, no matter when or how created, arising,
evidenced, or acquired, and whether or not presently contemplated or
anticipated, 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 LENDER shall be paid when and
as due, whether by reason of installment, maturity, acceleration or otherwise,
time being of the essence; and (c) the timely, complete, continuous, and strict
performance and observance by the BORROWER of each of the terms, covenants,
agreements and conditions contained in any and all existing or future documents,
instruments, agreements, and writings of every kind, nature, type, and variety
which evidence, reflect, embody, give rise to or secure any and all existing and
future indebtedness, liabilities, and obligations of any kind of the BORROWER to
the LENDER ("LOAN DOCUMENTS"). 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, both
as described in this Section and in other Sections of this GUARANTY.

     Section 2. Nature Of Guaranty. This GUARANTY: (a) is (i) irrevocable, (ii)
absolute and unconditional, (iii) direct, immediate, and primary, and (iv) one
of payment and not just collection; and (b) makes the GUARANTOR a surety to the
LENDER with respect to the OBLIGATIONS and the equivalent of a co-obligor with
the BORROWER. Without limiting the foregoing, it is specifically understood that
any modification, limitation or discharge of any of the liabilities or
obligations of the BORROWER, any other guarantor or any other obligor under any
of the LOAN DOCUMENTS,



arising out of, or by virtue of, any bankruptcy, arrangement, reorganization or
similar proceeding for relief of debtors under federal or state law initiated by
or against the BORROWER, any other guarantor or any obligor under any of the
LOAN DOCUMENTS shall not modify, limit, lessen, reduce, impair, discharge, or
otherwise affect the liability of the GUARANTOR hereunder in any manner
whatsoever, and this GUARANTY shall remain and continue in full force and
effect.

     Section 3. Accuracy Of Representations. The GUARANTOR guaranties that all
representations and warranties made by the BORROWER or by the GUARANTOR to the
LENDER prior to or after the date of this GUARANTY are and will be true,
correct, accurate, and, to the best of the GUARANTOR'S knowledge, complete and
not knowingly misleading, and the GUARANTOR agrees to indemnify and hold the
LENDER harmless from any loss, cost, or expense which the LENDER may suffer,
sustain or incur as a result of any representation or statement of the BORROWER
or of the GUARANTOR being materially false, incorrect, inaccurate, incomplete,
or knowingly misleading.

     Section 4. Representations Of Guarantor. To induce the LENDER to accept
this GUARANTY for the purposes for which it is given, the GUARANTOR represents
and warrants to the LENDER as follows:

          (a) The GUARANTOR is a corporation duly organized, validly existing
and in good standing under the laws of the state of its incorporation, and each
subsidiary of the GUARANTOR is a corporation duly organized, validly existing
and in good standing under the laws of the state of its incorporation. The
GUARANTOR and its subsidiaries have the lawful power to own their properties and
to engage in the businesses they conduct, and each is duly qualified and in good
standing as a foreign corporation in the jurisdictions wherein the nature of the
business transacted by it or property owned by it makes such qualification
necessary.

          (b) Any financial statements submitted by the GUARANTOR to the LENDER,
including any schedules and notes pertaining thereto, have been prepared in
accordance with generally accepted accounting principles consistently applied,
and fully and fairly present the financial condition of the GUARANTOR and its
subsidiaries at the dates thereof and the results of operations for the periods
covered thereby, and there has been no material adverse change in the
consolidated financial condition or businesses of the GUARANTOR and its
subsidiaries from the dates thereof to the date hereof, other than as disclosed
to the LENDER.

          (c) Neither the GUARANTOR nor any of its subsidiaries is in default
with respect to any of its existing indebtedness, and the making and performance
of this GUARANTY will not (immediately, with the passage of time, the giving of
notices, or both), (i) violate the charter or bylaws of the GUARANTOR, (ii)
violate any laws, (iii) result in a default under any contract, agreement, or
instrument to which the GUARANTOR or any of its subsidiaries is a party or by
which the GUARANTOR or any of its subsidiaries or its property is bound, or (iv)
result in the creation or imposition of any security interest in, or lien or
encumbrance upon, any of the assets of the GUARANTOR or any of its subsidiaries
except in favor of the LENDER.

          (d) The GUARANTOR has the power and authority to enter into and
perform this GUARANTY, and to incur the OBLIGATIONS, and has taken all corporate
action necessary to authorize the execution, delivery, and performance of this
GUARANTY.

          (e) This GUARANTY when delivered will be, valid, binding, and
enforceable in accordance with its terms.

                                       2



          (f) The incurring or satisfaction of the OBLIGATIONS has not left and
will not leave the GUARANTOR insolvent, with an unreasonably small capital, or
unable to pay existing or future debts as they mature.

     Section 5. Reporting Requirements. The GUARANTOR shall submit the following
items to the LENDER:

          (a) Within forty-five (45) calendar days after the end of each fiscal
quarter of the GUARANTOR, the GUARANTOR shall submit a copy of its 10Q filing
made with the Securities and Exchange Commission for such fiscal year.

          (b) Within one hundred twenty (120) calendar days after the end of
each fiscal year of the GUARANTOR, the GUARANTOR shall submit: (i) a
consolidated and consolidating statement of stockholders' equity and a
consolidated and consolidating statement of changes in the financial position of
the GUARANTOR and subsidiaries for such fiscal year; (ii) a consolidated and
consolidating income statement of the GUARANTOR and subsidiaries for such fiscal
year; and (iii) a consolidated and consolidating balance sheet of the GUARANTOR
and subsidiaries as of the end of such fiscal year. All financial statements
shall be in reasonable detail, including all supporting schedules and comments
necessary to verify or confirm entries in the financial statements. All
financial statements shall be prepared in accordance with generally accepted
accounting principles consistently applied and audited by an independent
certified public accountant, reasonably acceptable to the LENDER. The costs of
supplying the financial statements shall be paid by the GUARANTOR.

     Section 6. Lender Need Not Pursue Other Rights. The LENDER shall be under
no obligation to pursue any of the LENDER'S rights and remedies against the
BORROWER or any of the collateral of the BORROWER securing the obligations of
the BORROWER to the LENDER or against any other guarantor or any collateral of
any other guarantor before pursuing the LENDER'S rights and remedies against the
GUARANTOR.

     Section 7. Certain Rights Of Lender. The GUARANTOR hereby assents to any
and all terms and agreements between the LENDER and the BORROWER or between the
LENDER and any other guarantor, and all amendments and modifications thereof,
whether presently existing or hereafter made and whether oral or in writing. The
LENDER 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

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,

to the LENDER 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

renew, extend, or amend in any respect the LENDER'S agreement with the BORROWER
or any other guarantor, or any document, instrument, or writing embodying or
reflecting the same, including without limitation modifications which increase
the amount of the OBLIGATIONS or extend the maturity of the OBLIGATIONS.

the LENDER which are guarantied hereby are now or hereafter become invalid or
unenforceable for any reason.

     Section 10. 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 is 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 11. No Duty To Disclose. The LENDER shall have no present or future
duty or obligation to discover or to disclose to the GUARANTOR any information,

collateral securing either the obligations of the BORROWER to the LENDER or of
any other person who may have guarantied in whole or in part the obligations of
the BORROWER to the LENDER. The GUARANTOR waives any right to claim or assert

under any other LOAN DOCUMENT or in any capacity other than as GUARANTOR

                                       4



     Section 14. 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
LENDER, 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 LENDER in making demand on the GUARANTOR for satisfaction of the
OBLIGATIONS shall prejudice or in any way impair the LENDER'S ability to enforce
this GUARANTY.

     Section 15. Defenses Against Borrower. The GUARANTOR waives any right to
assert against the LENDER 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 16. Events Authorizing Acceleration Of The Obligations. The
occurrence of any of the following (each an "EVENT OF DEFAULT") shall entitle
the LENDER, without notice or demand, to accelerate and call due the
OBLIGATIONS, even if the LENDER has not accelerated and called due the sums owed
to the LENDER by the BORROWER: (a) the commencement by the BORROWER or the
GUARANTOR of a voluntary case or proceeding under any federal or state
bankruptcy, insolvency or similar law; (b) the commencement of an involuntary
case or proceeding against the BORROWER or the GUARANTOR under any federal or
state bankruptcy, insolvency, or similar law, and either (i) such case or
proceeding is not dismissed within ninety (90) calendar days after commencement,
or (ii) an order for relief is entered in such case; (c) the appointment of a
receiver, assignee, custodian, trustee or similar official under any federal or
state insolvency or creditors' rights law for any property of the BORROWER or
the GUARANTOR; (d) the entry of a judgment against the GUARANTOR or the BORROWER
and the failure to satisfy such judgment within thirty (30) days either by
payment or by the filing of a supersedeas bond; (e) a default by the BORROWER
under any of the LOAN DOCUMENTS or under any other agreement between the
BORROWER and the LENDER, and such default is not cured within any applicable
cure period; (f) a failure of the GUARANTOR to perform any covenant or agreement
contained in this GUARANTY or in any other agreement between the GUARANTOR and
the LENDER; (g) any representation or warranty made in this GUARANTY or in any
report or financial statement furnished in connection with this GUARANTY, shall
prove to have been false or misleading when made; (h) the LENDER in its sole
discretion determines in good faith that a material adverse change has occurred
in the financial condition of the GUARANTOR; (i) the death or the liquidation or
dissolution of the BORROWER or of the GUARANTOR; or (j) a failure of the
GUARANTOR to satisfy any of the obligations of the GUARANTOR to the LENDER with
respect to any loan or extension of credit by the LENDER to the GUARANTOR or
under any other guaranty given by the GUARANTOR to the LENDER.

     Section 17. Expenses Of Collection And Attorneys' Fees. Should this
GUARANTY be referred to an attorney for collection, the GUARANTOR shall pay all
of the holder's reasonable costs, fees and expenses resulting from such
referral, including reasonable attorneys' fees, which the holder may incur, even
though judgment has not been confessed or suit has not been filed.

     Section 18. Confession Of Judgment. Upon the occurrence of an EVENT OF
DEFAULT, the GUARANTOR authorizes any attorney admitted to practice before any
court of record in the

                                       5



United States, or the clerk of such court, to appear on behalf of the GUARANTOR
and to confess judgment in any such court against the GUARANTOR in the full
amount due on this GUARANTY at such time plus an attorneys' fee equal to fifteen
percent (15%) of the amount due. The GUARANTOR waives any right to notice or a
hearing prior to the entry of judgment and to the benefit of any and every
statute, ordinance, or rule of court which may be lawfully waived conferring
upon the GUARANTOR any right or privilege of exemption, appeal, 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 which the GUARANTOR has given for any attorney admitted to
practice before any court of record in the United States, or the clerk of such
court, to appear for and confess judgment against the GUARANTOR shall be a
continuous authority which shall not be exhausted or extinguished by any one or
more exercises or imperfect exercises thereof or by any one or more judgments
entered pursuant thereto and may be exercised on one or more occasions and at
such times and from time to time after default and in the same or different
courts or jurisdictions as the LENDER may consider necessary or advisable. In
the event that the LENDER receives, as a result of execution on a judgment
confessed hereunder, attorneys' fees which exceed the actual legal fees incurred
by the LENDER in connection with the enforcement of this GUARANTY, then upon
full and final payment of all other sums due and owing to the LENDER in
accordance with this GUARANTY and the payment to the LENDER of the actual
attorneys' fees incurred by the LENDER, the LENDER shall remit such excess
amount of attorneys' fees to the GUARANTOR.

     Section 19. Interest Rate After Judgment. 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 LOAN DOCUMENTS 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 LENDER an amount as will equal the interest computed at
the highest rate after default provided for in the LOAN DOCUMENTS which would be
due 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 20. Enforcement During Bankruptcy. 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 LENDER 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 LENDER to obtain the relief requested.

     Section 21. Remedies Cumulative. All of the LENDER'S rights and remedies
shall be cumulative and any failure of the LENDER to exercise any right
hereunder shall not be construed

                                       6



as a waiver of the right to exercise the same or any other right at any time,
and from time to time, thereafter.

     Section 22. Continuing Guaranty. This GUARANTY is a continuing guaranty of
all existing and future obligations of the BORROWER to the LENDER and may not be
terminated by the GUARANTOR until the LOAN DOCUMENTS are terminated, in
accordance with the provisions thereof, and the payment (which payment shall not
be subject to challenge or contest) in full of all of the OBLIGATIONS and all of
the BORROWER'S obligations and liabilities to the LENDER under the LOAN
DOCUMENTS.

     Section 23. 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 LOAN 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 LENDER to
the BORROWER or any other person or entity under any insolvency, bankruptcy or
other federal and/or state laws 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 24. Rights Of Subrogation, Etc. In the event the GUARANTOR pays any
sum to or for the benefit of the LENDER 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 BORROWER to the LENDER or the obligations of any other
guarantor to the LENDER until such time as the LENDER has 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 LENDER if some action of the LENDER, 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 LENDER pursuant to this GUARANTY.

     Section 25. 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 LENDER by the BORROWER.

     Section 26. Setoff. The LENDER shall have the right to setoff and apply
against the OBLIGATIONS any sums which the GUARANTOR at any time has on deposit
with the LENDER whether such deposits are general or special, time or demand,
provisional or final, and the GUARANTOR hereby pledges and grants to the LENDER
a security interest in all such deposits.

     Section 27. Renewals, Etc. This GUARANTY shall apply to all sums now or
hereafter owed by the BORROWER to the LENDER and to all extensions,
modifications, amendments, renewals, substitutions, and refinancings thereof.

     Section 28. 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

                                       7



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 29. Consent To Jurisdiction; Agreement As To Venue. The GUARANTOR
irrevocably consents to the non-exclusive jurisdiction of the courts of the
State of Maryland and of the United States District Court for the District of
Maryland, if a basis for federal jurisdiction exists. The GUARANTOR agrees that
venue shall be proper in any circuit court of the State of Maryland selected by
the LENDER or in the United States District Court for the District of Maryland
if a basis for federal jurisdiction exists 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 30. Proofs Of Sums Due On Guaranty. In any action or proceeding
brought by the LENDER to collect the sums owed on this GUARANTY, a certificate
signed by an officer of the LENDER setting forth the unpaid balances of
principal, and any accrued interest, default interest, attorneys' fees, and late
charges owed with respect hereto shall be presumed correct and shall be
admissible in evidence for the purpose of establishing the truth of what it
asserts.

     Section 31. Actions Against Lender. Any action brought by the GUARANTOR
against the LENDER which is based, directly or indirectly, on this GUARANTY or
any matter in or related to this GUARANTY, including but not limited to the
obligations of the BORROWER to the LENDER, the administration, collection, or
enforcement thereof, shall be brought only in the courts of the State of
Maryland. The GUARANTOR may not file a counterclaim against the LENDER in a suit
brought by the LENDER against the GUARANTOR in a state other than the State of
Maryland unless under the rules of procedure of the court in which the LENDER
brought the action or the counterclaim is mandatory, and not merely permissive,
and will be considered waived unless filed as a counterclaim in the action
instituted by the LENDER. 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 LENDER 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.

     Section 32. 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 33. Amendment Or Waiver. This GUARANTY may be amended only by a
writing duly executed by the GUARANTOR and the LENDER. No waiver by the LENDER
of any of the provisions of this GUARANTY or any of the rights or remedies of
the LENDER with respect hereto shall be considered effective or enforceable
unless in writing.

     Section 34. Notices. Any notice required or permitted by or in connection
with this GUARANTY 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 electronic mail, by hand delivery, by
Federal Express, or other similar overnight delivery service, or by certified
mail,

                                       8



unrestricted delivery, return receipt requested, postage prepaid, addressed to
the LENDER 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 LENDER
or the GUARANTOR. Notice shall be considered given as of the date of the
facsimile or the hand delivery, as of the date of receipt of confirmation that
the electronic mail was received and opened, 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 case may be, provided the giver of
notice can establish the fact that notice was given as provided herein. If
notice is tendered pursuant to the provisions of this Section and is refused by
the intended recipient thereof, the notice, nevertheless, shall be considered to
have been given and shall be effective as of the date herein provided.
