without regard as to whether the obligations of the BORROWERS under the LOAN


                                       24
<PAGE>

DOCUMENTS have been accelerated, are in default, or are being paid as agreed by
the BORROWERS in accordance with the terms of the LOAN DOCUMENTS.

         Section 9. LENDER NEED NOT PURSUE OTHER RIGHTS. The LENDER shall be
under no obligation to pursue the LENDER'S rights against the BORROWERS or any
GUARANTOR or any other guarantor or source of repayment before pursuing the
LENDER'S rights against any other GUARANTOR.

         Section 10. ENFORCEMENT OF LIENS. Upon the acceleration of the payment
of the OBLIGATIONS as authorized by this GUARANTY, the LENDER may, in addition
to all other rights and remedies provided by applicable LAWS or the LOAN
DOCUMENTS, 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. Without limitation to the foregoing, 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 interests which the
GUARANTORS may have therein. Pending any such action, the LENDER may collect and
liquidate such 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 shall be given to the GUARANTORS at least ten (10)
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 GUARANTORS hereby agree shall be commercially reasonable notice of
such sale or other disposition. The GUARANTORS shall assemble, or shall cause to
be assembled, at the GUARANTORS' 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 permissible under applicable law, purchase the whole
or any part of the COLLATERAL, free from any right of redemption on the part of
the GUARANTORS, 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 GUARANTORS,
exclude therefrom the GUARANTORS 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 11. CONFESSION OF JUDGMENT. Upon the occurrence of an EVENT OF
DEFAULT, each of the GUARANTORS authorizes any attorney admitted to practice
before any court of record in the United States, or the clerk of such court, to
appear on behalf of it and to confess judgment in any such court against it in
the full amount due on this GUARANTY at such time plus attorneys' fees equal to
fifteen percent (15%) of the amount due on this GUARANTY and court



                                       25
<PAGE>

costs. Each of 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 GUARANTORS 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
each of the GUARANTORS 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 each of the GUARANTORS 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, amounts in respect of attorneys' fees which exceed the actual legal
fees incurred by the LENDER in connection with this GUARANTY, then, upon full
and final payment of all of the other OBLIGATIONS, the LENDER shall remit such
excess to the GUARANTORS.

         Section 12. SUBROGATION. Each of the GUARANTORS hereby irrevocably
agrees to subordinate any SUBROGATION RIGHTS to the rights of the LENDER (and
its assigns and successors in interest) to recover from the BORROWERS or any
other GUARANTOR or any other PERSON with respect to any payments made or
obligations incurred as a result of this GUARANTY. To effectuate such
subordination, each of the GUARANTORS hereby agrees that it shall not be
entitled to any payment from the BORROWERS or from any other GUARANTOR or PERSON
in respect of any SUBROGATION RIGHT until all of the OBLIGATIONS have been
indefeasibly paid in full. If any amount shall be paid to any GUARANTOR in
violation of the preceding sentence and the OBLIGATIONS shall not have been paid
in full, such amount shall be deemed to have been paid to such GUARANTOR for the
benefit of, and held in trust for, the LENDER (and its assigns and successors in
interest), and shall forthwith be paid to the LENDER (or its assigns or
successors in interest) to be credited and applied to the OBLIGATIONS, whether
matured or unmatured. Each of the GUARANTORS acknowledges that it will receive
direct and indirect benefits from the credit transactions contemplated by the
LOAN DOCUMENTS and that the subordination set forth in this Section is knowingly
made in contemplation of obtaining such benefits.

         Section 13. RIGHT OF CONTRIBUTION. Each of the GUARANTORS hereby agrees
that to the extent that a GUARANTOR shall have paid more than its proportionate
share of any payment made hereunder upon the OBLIGATIONS, such GUARANTOR shall
be entitled to seek and receive contribution from and against any other
GUARANTOR hereunder which has not paid its proportionate share of such payment.
Each GUARANTOR'S right of contribution shall be subject to the terms and
subordination conditions of this GUARANTY. The provisions of this Section shall
in no respect limit the obligations and liabilities of any GUARANTOR hereunder
and each GUARANTOR shall remain jointly and severally liable for the full amount
guaranteed by the GUARANTORS hereunder.

         Section 14. CERTAIN RIGHTS OF LENDER. Each of the GUARANTORS hereby
assents to any and all terms and agreements between the LENDER and the



                                       26
<PAGE>

BORROWERS 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 GUARANTORS from the GUARANTORS' duties
to pay and perform the OBLIGATIONS and without notifying or obtaining the prior
approval of any of the GUARANTORS, at any time or from time to time: (a) waive
or excuse a default by the BORROWERS or any other GUARANTOR, or delay in the
exercise of any or all of the LENDER'S rights or remedies with respect to such
default or defaults; (b) grant extensions of time for payment or performance by
the BORROWERS or any other GUARANTOR; (c) release, substitute, exchange,
surrender, or add collateral of the BORROWERS or of any other GUARANTOR, or
waive, release, or subordinate, in whole or in part, any lien or security
interest held by the LENDER on any real or personal property securing payment or
performance, in whole or in part, of the obligations of the BORROWERS to the
LENDER or of any other GUARANTOR or any other PERSON; (d) release the BORROWERS
or any other GUARANTOR or other PERSON from any duties or obligations owed by
the BORROWERS or any other GUARANTOR or other PERSON to the LENDER; (e) increase
the obligations of the BORROWERS under the LOAN DOCUMENTS; and (f) modify,
change, renew, extend, terminate, or amend in any respect any of the LOAN
DOCUMENTS or the LENDER'S agreements with the BORROWERS or with any other
GUARANTOR.

         Section 15. WAIVERS BY GUARANTORS. Each of the GUARANTORS waives: (a)
any and all notices whatsoever with respect to this GUARANTY or with respect to
any of the obligations owed by the BORROWERS to the LENDER, including, but not
limited to, notice of (i) the acceptance hereof by the LENDER or of the
intention to act by the LENDER, or any action taken by the LENDER in reliance
hereon, (ii) the present existence or future incurring of any of the obligations
of the BORROWERS to the LENDER or any terms or amounts thereof or any change
therein, (iii) any default by the BORROWERS or any surety, pledgor, grantor of
security, or any PERSON who has guaranteed or secured in whole or in part any of
the obligations of the BORROWERS to the LENDER, and (iv) the obtaining or
release of any guaranty or surety agreement, pledge, assignment, or other
security for any of the obligations of the BORROWERS to the LENDER; (b)
presentment and demand for payment of any sum due from the BORROWERS or any
other GUARANTOR and protest of nonpayment; (c) demand for performance by the
BORROWERS or any other GUARANTOR; and (d) any defenses to this GUARANTY or the
payment and performance of the OBLIGATIONS based upon any suretyship or
impairment of collateral.

         Section 16. UNENFORCEABILITY OF OBLIGATIONS OF BORROWERS. This GUARANTY
shall be valid, binding, and enforceable even if any or all of the obligations
of the BORROWERS to the LENDER which are guaranteed hereby are now, or
hereafter, become invalid or unenforceable for any reason, or are set aside,
avoided or determined to have been invalid for any reason, in whole or in part.

         Section 17. NO CONDITIONS PRECEDENT. This GUARANTY shall be effective
and enforceable immediately upon its execution. The GUARANTORS acknowledge 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



                                       27
<PAGE>

any event, occurrence, or happening, or upon any condition existing or coming
into existence either before or after the execution of this GUARANTY.

         Section 18. NO DUTY TO DISCLOSE. The LENDER shall not have any present
or future duty or obligation to discover or to disclose to any GUARANTOR any
information, financial or otherwise, concerning the BORROWERS, any other
GUARANTOR, the LOAN, the LOAN DOCUMENTS, or any collateral securing the
obligations of the BORROWERS to the LENDER or of any other PERSON who may have
guaranteed in whole or in part the obligations of the BORROWERS to the LENDER.
Each of the GUARANTORS waives any right to claim or assert any such duty or
obligation on the part of the LENDER. The GUARANTORS agree to obtain all
information which the GUARANTORS consider either appropriate or relevant to this
GUARANTY and the agreements and undertakings of the GUARANTORS hereunder from
sources other than the LENDER and to become and remain at all times current and
continuously apprised of all information concerning the BORROWERS, other
GUARANTORS, the LOAN, or the LOAN DOCUMENTS which the GUARANTORS consider to be
material or relevant to the duties of the GUARANTORS pursuant to this GUARANTY
or the payment and performance of the OBLIGATIONS by the GUARANTORS.

         Section 19. ENFORCEMENT DURING BANKRUPTCY. Enforcement of this GUARANTY
against any GUARANTOR 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 either of the BORROWERS or any other GUARANTOR. Should the LENDER (or
the assignee or successor in interest thereof) 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 any GUARANTOR, such 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 (or the assignee or successor
in interest thereof) to obtain the relief requested.

         Section 20. CUMULATIVE  LIABILITY.  The liability of the  GUARANTORS to
the LENDER pursuant to this GUARANTY shall be cumulative to, and not in lieu of,
all other duties, obligations and liabilities owed by any of the GUARANTORS to
the LENDER from time to time.

         Section 21. OBLIGATIONS ARE UNCONDITIONAL. The payment and performance
of the OBLIGATIONS shall be the absolute and unconditional duty and obligation
of each of the GUARANTORS, and shall be independent of any defense or any rights
of set-off, recoupment or counterclaim which any of the GUARANTORS might
otherwise have against the LENDER. The GUARANTORS shall pay and perform all
OBLIGATIONS, free of any deductions and without abatement, diminution or
set-off. Until such time as the OBLIGATIONS have been fully paid and performed,
each 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, in whole or in part, for any reason. No delay by the LENDER in
making demand upon the GUARANTORS for satisfaction of the OBLIGATIONS shall
prejudice or in any way impair the ability of the LENDER to enforce this
GUARANTY.


                                       28
<PAGE>

         Section 22. DEFENSES AGAINST BORROWERS. Until the OBLIGATIONS of the
GUARANTORS hereunder have been satisfied in full, each of the GUARANTOR waives
any right to assert against either of the BORROWERS any defense (whether legal
or equitable), claim, counterclaim, or right of set-off or recoupment which the
GUARANTORS may now or hereafter have against the BORROWERS or any other
GUARANTOR or PERSON.

         Section 23. 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 as a waiver of the right to exercise the same
or any other right at any time, and from time to time, thereafter.

         Section 24. DISCHARGE OF GUARANTY. This GUARANTY shall not be
discharged and the GUARANTORS shall not be released from liability until all
OBLIGATIONS (including contingent OBLIGATIONS) have been paid, performed and
satisfied in full and the satisfaction of the OBLIGATIONS is not subject to
challenge, contest or any other potential contingency. If all or any portion of
the OBLIGATIONS are satisfied and the LENDER is required by order of a court of
competent jurisdiction to pay to any PERSON the sums used to satisfy the
OBLIGATIONS, the OBLIGATIONS shall remain in effect and enforceable to the
extent thereof.

         Section 25. SUBORDINATION OF CERTAIN INDEBTEDNESS. If any of the
GUARANTORS has advanced or advances any sums to the BORROWERS or their
successors or assigns or if the BORROWERS or their successors or assigns shall
hereafter become indebted to the GUARANTOR, such sums and indebtedness shall be
subordinate in payment and right of enforcement and in all other respects to the
amounts then or thereafter due and owing to the LENDER by the BORROWERS.

         Section 26. EXCHANGE OF INFORMATION. Each of the GUARANTORS irrevocably
authorizes the LENDER to share and discuss with any holder of SUBORDINATED DEBT
such information concerning the GUARANTORS, the BORROWERS, the OBLIGATIONS, the
LOAN, the COLLATERAL, this GUARANTY and the finances, business affairs and
operations of the GUARANTORS and the BORROWERS as the LENDER may desire from
time to time without any notice or consent from the GUARANTORS. The GUARANTORS
also authorize any holder of SUBORDINATED DEBT to share and discuss any such
information with the LENDER.

         Section 27. 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 28. CONSENT TO JURISDICTION; AGREEMENT AS TO VENUE. Each of the
GUARANTORS 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. Each of the
GUARANTORS agrees that venue shall be proper in any circuit court of



                                       29
<PAGE>

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 29. 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 30. AMENDMENT OR WAIVER. This GUARANTY may be amended only by a
writing duly executed by the GUARANTORS and by 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 31. NOTICES. Any notice required or permitted by or in
