     Amount is unused.

     equal to 1.5% per draw to be paid in advance.  In addition, Borrower shall

     Revolving Commitment Amount.  The provisions of the Letter of Credit
     agreement are deemed incorporated in this Agreement by this reference and
     shall be binding upon the Lender and Borrower as if fully set forth herein.

     and any other Loan Document, the terms of the Letter of Credit agreement
     shall control with respect to any Letter of Credit issued pursuant to such

damages, including attorneys' fees and expenses, that Lender may incur as a
result of the foregoing events or occurrences for which the Borrower has assumed
the risk of loss.

     ARTICLE 4.  SECURITY.
     --------------------

     4.1       Grant of Security Interest.  As security for (i) the payment of
               --------------------------
the Loan, and any other extensions of credit, loans, letters of credit or other
financial accommodations now or hereafter made by the Lender for the benefit of
the Borrower,  and (ii) for any other liability or obligation of Borrower to
Lender whether now or hereafter existing, of every kind and description, whether
or not evidenced by notes or other instruments, and whether  or not such
liability or obligations are direct or indirect, fixed or contingent, liquidated
or unliquidated, the Borrower hereby assigns, grants and conveys to the Lender a
security interest in the Collateral.  In addition, except as prohibited by law,
Borrower grants to Lender a security interest in all accounts of Borrower with
Lender or any of Lender's Affiliates.  The Borrower further agrees that the
Lender shall have in respect of the Collateral all of the rights and remedies of
a secured party under the Uniform Commercial Code, other applicable law and this
Agreement.  The Borrower covenants and agrees to execute and deliver such
financing statements and other instruments and filings or perform any and all
acts as are necessary in the opinion of the Lender to perfect, maintain and
protect the security interest hereby granted.  The Borrower shall not
<PAGE>

dispose of the Collateral, or any part thereof, other than in the ordinary
course of its business or as otherwise may be permitted by this Agreement.

     4.2       Certain Rights of the Lender.    The Lender shall have the right,
               ----------------------------
but not the obligation, (i) to pay any taxes or levies on the Collateral or any
costs to repair or to preserve the Collateral; and (ii) to cure any defaults by
Borrower on contracts by the Borrower intended to give rise to Accounts.  Such
payments and the costs of curing such defaults shall constitute Advances under
either the Revolving Note or the Guidance Line of Credit, as applicable, and
shall be secured pursuant to this Agreement notwithstanding that such Advances
may cause the unpaid principal balance of the Loan to exceed the Maximum
Revolving Commitment Amount.

     4.3       Financing Statements.  At the request of the Lender, Borrower
               --------------------
will join with the Lender in executing financing statements, continuation
statements and other documents with respect to the Collateral pursuant to the
Uniform Commercial Code or otherwise, in form satisfactory to the Lender, and
Borrower will pay the cost of filing the same in all public offices wherever the
Lender deems filing to be necessary or desirable.  Borrower agrees that a
carbon, photographic, photostatic or other reproduction of this Agreement or of
a financing statement is sufficient as a financing statement; provided, however,
that it shall not limit the obligations of Borrower as previously set forth
herein.  Borrower grants the Lender the right, at the Lender's option, to file
any or all such financing statements, continuation statements and other
documents pursuant to the Uniform Commercial Code and otherwise, without
Borrower's signature, and irrevocably appoints the Lender as Borrower's
attorney-in-fact to execute any such statements and documents in Borrower's name
and to perform all other acts which the Lender deems appropriate to perfect and
to continue the security interests conferred by this Agreement.

     4.4       Records of Collateral; Information.  Borrower at all times will
               ----------------------------------
maintain accurate books and records covering the Collateral.  Borrower
immediately will mark all books and records with an entry showing the absolute
assignment of and granting of a security interest in all Collateral to Lender,
and hereby grants the Lender the right to audit the books and records of
Borrower relating to Collateral at any time and from time to time.  Borrower
shall (i) promptly furnish the Lender with any information with respect to
Collateral requested by Lender; (ii) allow the Lender or its representatives to
inspect the Collateral, at any time and wherever located, and to inspect and
copy, or furnish the Lender or its representatives with copies of all records
relating to the Collateral; (iii) furnish the Lender or its representatives such
information as the Lender may request to identify the Collateral, at the time
and in the form requested by Lender; and (iv) deliver upon request to Lender
shipping and delivery receipts evidencing the shipment of goods and invoices
evidencing the receipt of the Collateral and payment for the Collateral.

     4.5       No Release.  No injury to the Collateral, loss or destruction of
               ----------
the Collateral, failure to perfect or to continue the perfection of Lender's
security interest in the Collateral, or release of Lender's security interest in
the Collateral, or any part of it, shall relieve Borrower of any obligation
under this Agreement or under any of the other Loan Documents.  Borrower
expressly waives all defenses based on suretyship or impairment of collateral,
and shall not be released or discharged of any obligation under the Loan
Documents, in whole or in part, by Lender's failure to protect or preserve the
Collateral.  No Person, in deciding to enter into this Loan Agreement, has
relied on the execution of this Loan Agreement or the granting of a
<PAGE>

security interest in Collateral by any other Person. Each Person comprised by
the term Borrower waives notice of any change in financial condition of any
Person liable for the Loans or any part thereof, and agrees that maturity of the
Loans or any part thereof may be accelerated, extended or renewed one or more
times by Lender in its discretion, without notice to the Person and without
affecting Lender's security interest in the Collateral. Lender shall not be
required to bring any action against any other Person or to resort to any other
security or to any balance of any deposit account as a condition of enforcing
its rights against any of the Collateral.

     4.6       Assignment of Payments Under Certain Government Contracts and
               -------------------------------------------------------------
Government Accounts.  Lender may, in its sole discretion, require that Borrower
-------------------
execute and deliver to the Lender specific Assignments of Payments due or to
become due with respect to any Government Account designated by the Lender.
Borrower shall execute and deliver any and all documents and take any and all
steps necessary to provide the Lender with an Assignment.  The separate
Assignment to the Lender of a right to payment under specific Government
Contracts, as contemplated under this Section, shall not be deemed to limit the
Lender's security interest to Payments under those particular Government
Contracts and the related Government Accounts, but rather the Lender's security
interest, as stated above, shall extend to Payments under any and all Government
Contracts and the related Government Accounts and proceeds thereof, now or
hereafter owned or acquired by Borrower.

     4.7       Additional Remedy for Failure to Assign Payments.  Borrower
               ------------------------------------------------
acknowledges that the Lender will be irreparably harmed if Borrower fails to
assign Payments due or to become due under any Government Contract when required
by this Agreement, and that the Lender shall have no adequate remedy at law.
Therefore, the Borrower agrees that the Lender shall be entitled, in addition to
all other remedies allowed by law or under this Agreement, to injunctive or
other equitable relief to compel Borrower's compliance with the provisions of
this Agreement requiring the Borrower to assign Payments due or to become due
under any Government Contract.

     4.8       Indemnification.  In any suit, proceeding or action brought by or
               ---------------
against the Lender relating to the Collateral, the Borrower will save, indemnify
and keep the Lender harmless from and against all reasonable expense, loss or
damage suffered by reason of any defense, set-off, counterclaim, recoupment or
reduction of liability whatsoever of any obligor thereunder, arising out of a
breach by the Borrower of any obligation thereunder or arising out of any other
agreement, indebtedness or liability at any time owing to or in favor of such
obligor or its successors from the Borrower, and all such obligations of the
Borrower shall be and remain enforceable against and only against the Borrower
and shall not be enforceable against the Lender.  The foregoing obligation of
the Borrower to indemnify the Lender shall survive the payment of the Loans and
the termination of this Agreement but shall not extend to any suit, proceeding
or action arising out of the Lender's gross negligence or willful misconduct.
<PAGE>

     ARTICLE 5.  BORROWER'S REPRESENTATIONS AND WARRANTIES.

     To induce the Lender to enter into this Agreement and to extend the
Revolving Loan and the Guidance Line of Credit to Borrower, Borrower makes the
following representations and warranties to the Lender.  These representations

or by any other Person is or will be necessary to permit the valid execution,
delivery or performance by Borrower of this Agreement or any of the other Loan
Documents.
<PAGE>

     5.3  Binding Effect, No Violations.  Each of the Loan Documents, upon its
          -----------------------------
execution and delivery, will constitute a legal, valid and binding obligation of
Borrower, enforceable against Borrower in accordance with its terms.  The
execution, delivery and performance of the Loan Documents will not (i) violate,
conflict with or constitute a default (with due notice, lapse of time or both)
under any law, regulation, order or any other requirement of any court,
tribunal, arbitrator or governmental authority, any terms of the Articles or
Certificate of Incorporation or Bylaws of Borrower, or any contract, agreement
or other arrangement binding upon or affecting Borrower or any of its
properties, or (ii) result in the creation, imposition or acceleration of any
indebtedness or any Encumbrance of any nature upon, or with respect to, Borrower
or any of its properties, except such Encumbrances in favor of Lender.

     5.4  Litigation.  Except as set forth in Exhibit D attached hereto and made
          ----------                          ---------
a part hereof, previously disclosed to the Lender in writing, there is no claim,
litigation, proceeding or investigation pending, threatened or reasonably
anticipated against or affecting Borrower, its properties or business, this
Agreement, any of the other Loan Documents, or any of the transactions
contemplated hereby or thereby, before or by any court, tribunal, arbitrator or
governmental authority, and there is no possibility of any judgment, liability
or award which reasonably may be expected to result in any material adverse
change in the business, operations, prospects, properties or assets or
condition, financial or otherwise, of Borrower.  Borrower is not in default with
respect to any judgment, order, writ, injunction, decree, rule, award or
regulation of any court, governmental instrumentality or agency, commission,
board, bureau, arbitrator or arbitration panel.

     5.5  Title to and Condition of Assets.  Except as previously disclosed to
          --------------------------------
the Lender by Borrower in writing, the Borrower has good, valid and marketable
title to all of its properties and assets (whether real or personal), and there
exist no Encumbrances on any of Borrower's properties or assets, including
without limitation, the Collateral.  All personal property of Borrower which is
necessary for Borrower's operations is in good operating condition and repair,
and is suitable and adequate for the uses for which it is being used.  Upon the
execution and delivery of this Agreement, and upon the filing of financing
statements or the Lender's taking possession of the Collateral, as the case may
be, the Lender will have a good, valid and perfected first priority lien and
security interest in the Collateral, subject to no Encumbrance in favor of any
other Person.

     5.6  Loan Application.  The statements made and the documents delivered by
          ----------------
Borrower to the Lender in connection with its application for the Revolving Loan
and the Guidance Line of Credit, and in connection with this Agreement and the
other Loan Documents are true, correct and complete, in all material respects,
omit no material facts, are not misleading, and present fairly the condition
(financial or otherwise) of Borrower.

     5.7  No Change.  No change in the business, operations, properties or
          ---------
condition (financial or otherwise) of Borrower or Guarantor, or any other event,
has occurred since the date of the most recent financial statements submitted to
the Lender by Borrower, which change might adversely affect the ability of
Borrower to perform or comply with all terms, conditions and agreements to be
performed or complied with by Borrower under this Agreement or under any of the
other Loan Documents, or to perform the transactions contemplated by this
<PAGE>

Agreement or the other Loan Documents.

     5.8  Taxes.  Borrower has timely filed all tax returns and reports required
          -----
by any governmental authority to be filed by Borrower, and such returns and
reports are true and correct.  Borrower has paid all taxes, assessments and
other government charges imposed upon it or its income, profits or properties,
or upon any part thereof, other than those presently payable without penalty or
interest and Borrower has timely filed all claims for refunds to which Borrower
is entitled.  The amounts reserved as a liability for income and other taxes
payable in the most recent financial statements of Borrower provided to the
Lender are sufficient for the payment of all unpaid federal, state, county and
local income, excise, property and other taxes, whether or not disputed, of
Borrower accrued for or applicable to the period and on the dates of such
financial statements and all years and periods prior thereto, and for which
Borrower may be liable in its own right or as a transferee of the assets of, or
as successor to, any other Person.

     5.9  No Event of Default.  As of the date this representation and warranty
          -------------------
is made (or remade), no Event of Default, and no event which with notice, lapse
of time or other condition would constitute an Event of Default, has occurred
and is continuing.

     5.10  Compliance with Laws, Governance Documents and Agreements.  Borrower
           ---------------------------------------------------------
has complied and is in full compliance in all material respects with all
applicable laws, ordinances, rules, regulations, orders and other requirements
of any governmental authority or arbitrator, and with all terms and conditions
of its Governance Documents, and with each agreement binding upon or affecting
Borrower or any of its properties.  Borrower is not in default with respect to
any Debt.  Borrower will take all necessary actions to remain in full compliance
with such laws, ordinances, rules, regulations, orders and any other
requirements, the Governance Documents and all other agreements.  Should
Borrower be deemed by any governmental authority or deem itself to be in
violation of any relevant law, ordinance, rule, regulation, orders or other
requirement, Governance Document or agreement, Borrower shall notify the Lender
promptly of such violation and take all necessary remedial actions.  Without
limiting the generality of the foregoing, Borrower represents to Lender that:
(1) Borrower has previously disclosed to Lender all of Borrower's activities
that involve the use, manufacturing, storage, disposal, emission, discharge,
generation or transportation of Hazardous Wastes, Toxic Substances or other
materials regulated by Environmental Laws; (2) Borrower has complied and is in
full compliance with all Environmental Laws; (3) Borrower maintains in full
force and effect all permits required by Environmental Laws; and (4) there
exists no pending or threatened litigation, order, ruling, notice or
investigation regarding the Borrower's use, manufacturing, storage, disposal,
emission, discharge generation or transportation of Hazardous Wastes or Toxic
Substances or regarding any violation or alleged violation of any Environmental
Laws.

     5.11  Licenses and Contracts.  All franchises, licenses, trademarks, trade
           ----------------------
names, copyrights, patents, permits, certificates, consents, approvals,
authorizations, agreements and contracts necessary to operate Borrower's
business as it currently is being operated and to own or lease Borrower's
property have been obtained, are in effect, have been complied with in all
material respects by Borrower, are free from challenge, and to the best of
Borrower's knowledge are fully assignable to the Lender for the purpose of
securing the Revolving Loan and the Guidance Line of Credit.  Borrower has no
knowledge and has not received any notice to the effect that any product it
manufactures or sells, or any service it renders, or any process, method,
<PAGE>

know-how, trade secret, part or material it employs in the manufacture of any
product it makes or sells or any service it renders, or the marketing or use by
it or another of any such product or service, may infringe any trademark, trade
name, copyright, patent, trade secret or legally protected right of any other
Person.

     5.12  Intellectual Property.  The Borrower owns all right, title and
           ---------------------
interest in and to all Intellectual Property used in and material to the
operation of its business or, for such Intellectual Property that is not owned,
possesses adequate licenses or other legally enforceable rights to use the same.
The Borrower has no reason to believe that any valid basis exists upon which a
claim adversely affecting any such Intellectual Property may be asserted against
the Borrower or any subsidiary.  To the best knowledge of the Borrower, no
Person is infringing upon the Intellectual Property used by the Borrower or any
subsidiary material to the operation of their respective businesses.  The
Borrower has taken appropriate steps to protect the secrecy, confidentiality and
value of its and all subsidiaries' rights in and to such Intellectual Property
and to prevent others from using such Intellectual Property without consent.

     5.13  Disclosure.  No representation or warranty of Borrower contained in
           ----------
this Agreement or any of the Loan Documents and no written statement of fact
furnished or to be furnished by Borrower to the Lender pursuant to this
Agreement or any of the Loan Documents, when viewed together, contains or will
contain any untrue statement of a fact material to the financial condition of
Borrower, or omits or will omit to state any material fact necessary in order to
make the statements contained herein or therein, or furnished herewith or
therewith, not misleading.

     5.14  Trade Name; Merger.  During the five years immediately preceding the
           ------------------
date of this Agreement, neither the Borrower nor any predecessor of the Borrower
has used any corporate or fictitious name other than its current corporate name.
Borrower utilizes no trade names in the conduct of its business, except as
disclosed in writing to the Lender, and has not changed its name, or been the
surviving entity in a merger or acquired any business.

     5.15  Payment of Employees and Subcontractors.  Borrower is not in default
           ---------------------------------------
with regard to the payment of any employee or subcontractor.

     5.16  ERISA  Borrower is in compliance with Borrower's obligations under
           -----
ERISA.  Without limiting the generality of the foregoing:

               a.  During the five-year period prior to the date on which this
representation is made or deemed made; (i) no Termination Event has occurred,
and, to the best of the Borrower's knowledge, no event or condition has occurred
or exists as a result of which any Termination Event could reasonably be
expected to occur, with respect to any Plan; (ii) no "accumulated funding
deficiency," as such term is defined in Section 302 of ERISA and Section 412 of
the Code, whether or not waived, has occurred with respect to any Plan; (iii)
each Plan has been maintained, operated and funded in compliance with its own
terms and in material compliance with the provisions of ERISA, the Code, and any
other applicable federal or state laws; and (iv) no lien in favor of the PBGC or
a Plan has arisen or is reasonably likely to arise on account of any Plan.
<PAGE>

               b.  The actuarial present value of all "benefit liabilities"
under each Single Employer Plan (determined within the meaning of Section
401(a)(2) of the Code, utilizing the actuarial assumptions used to fund such
Plans), whether or not vested, did not, as of the last annual valuation date
prior to the date on which this representation is made or deemed made, exceed
the current value of the assets of such Plan allocable to such accrued
liabilities.

               c.  Neither the Borrower nor any of its subsidiaries nor any
ERISA Affiliate has incurred, or, to the best of the Borrower's knowledge, are
reasonably expected to incur any withdrawal liability under ERISA to any
Multiemployer Plan or Multiple Employer Plan. Neither the Borrower, any of its
subsidiaries nor any ERISA Affiliate has received any notification that any
Multiemployer Plan is in reorganization (within the meaning of Section 4241 of
ERISA), is insolvent (within the meaning of Section 4245 of ERISA), or has been
terminated (within the meaning of Title IV of ERISA), and no Multiemployer Plan
is, to the best knowledge of the Borrower, reasonably expected to be in
reorganization, insolvent or terminated.

              d.  No prohibited transaction (within the meaning of Section 406
of ERISA or Section 4975 of the Code) or breach of fiduciary responsibility has
occurred with respect to a Plan which has subjected or may subject the Borrower
or any of its subsidiaries or any ERISA Affiliate to any liability under
Sections 406, 409, 502(i), or 502(l) of ERISA or Section 4975 of the Code, or
under any agreement or other instrument pursuant to which the Borrower or any of
its subsidiaries or any ERISA Affiliate has agreed or is required to indemnify
any Person against any such liability.

     5.17  Supporting Documentation is Correct.  All documents, financial
           -----------------------------------

are and will be true and correct in all material respects.

     5.18  Regarding the Representations and Warranties.  The representations
           --------------------------------------------
and warranties made in this Agreement and all of the other Loan Documents (i) do
not and will not contain, at the time furnished, any untrue statement of a
material fact; and (ii) do not and will not omit to state any material fact
necessary in order to make the statements contained therein not misleading.

     5.19  Representations and Warranties Deemed Redated and Remade.  The

representations and warranties made in this Agreement and all of the other Loan
Documents are made as of the date of this Agreement and shall be deemed remade
and redated as of the date of each advance of proceeds under any of the Loans
and date of issuance of each Letter of Credit.

           --------------------
terms of any Government Contract, and no Government Contract has been canceled

Borrower's Government Contracts.

     5.23  Assignment of Claims Act.  In the event that Lender receives  a
           ------------------------
direct assignment of Payments under a Government Contract, Borrower shall be in
compliance with any and all of the requirements of the Assignment of Claims Act,
where such statutes are applicable to any Government Contract, and shall take
all such other action as may be necessary to facilitate the assignment and
perfection of the Lender's interest in Payments under any Government Contract.

or any instrument received in payment thereof or for any damage resulting
therefrom.  The Lender is authorized to accept the return of the goods
represented by any of the Accounts, without notice to or consent by Borrower, or
without discharging or in any manner affecting either the Revolving Loan or the
Guidance Line of Credit, as applicable.  Upon receipt of any returned or
rejected goods, Borrower shall immediately issue and deliver a credit memo to

prices, to such purchasers, and upon such terms as the Lender deems advisable.

costs and expenses of such sale, including reasonable attorneys' fees.  Borrower
shall use its best efforts and shall take any and all steps necessary to collect

liability under Section 406, 409, 502(i), or 502(l) of ERISA or Section 4975 of
the Code, or under any agreement or other instrument pursuant to which the
Borrower or any of its subsidiaries or any ERISA Affiliate has agreed or is
required to indemnify any person against any such liability.

     9.2  Rights and Remedies of the Lender.  Upon the occurrence of any Event
          ---------------------------------
of Default, the Lender may, at its option, exercise any one or more of the
following rights and remedies:

          a.  Declare this Agreement and the Lender's obligation to make or
extend any Advances on the Revolving Loan and the Guidance Line of Credit to be
terminated, and declare the entire unpaid principal amounts of the Revolving
Loan and the Guidance Line of Credit, all interest accrued and unpaid thereon,
and all other amounts payable under this Agreement and the other Loan Documents
to be accelerated, and to be immediately due and payable (except that upon the
occurrence of an Event of Default arising out of voluntary or involuntary
bankruptcy proceedings in which the Borrower is the debtor, such acceleration
shall occur automatically and immediately without any declaration or other
action on the part of the Lender) whereupon the Revolving Loan and the Guidance
Line of Credit, all such accrued interest, and all such amounts shall become and
be immediately due and payable, without presentment, demand, protest or
<PAGE>

further notice of any kind, all of which are hereby expressly waived by
Borrower, anything contained herein or in any of the other Loan Documents to the
contrary notwithstanding;

          b.  Take possession or control of, store, lease, operate, manage, sell
or otherwise dispose of all or any part of the Collateral in accordance with the
remedies provided to secured parties under the Uniform Commercial Code, this
Agreement, the Loan Documents or other applicable law. In taking possession of
the Collateral, the Lender may enter the Borrower's premises and otherwise
proceed without legal process, and the Borrower shall on the Lender's demand,
promptly assemble and make the Collateral available to the Lender at a place
designated by the Lender. The Lender shall be entitled to immediate possession
of all books and records evidencing or pertaining to any of the Collateral;

          c.  Notify any or all Customers to make any Payments due to Borrower
from such Customers directly to the Lender. To facilitate direct collection,
Borrower hereby appoints the Lender and any officer or employee of the Lender,
as the Lender may from time to time designate, as attorney-in-fact for Borrower
to (i) receive, open and dispose of all mail addressed to Borrower and take
therefrom any Payments on or proceeds of Accounts; (ii) take over Borrower's
post office boxes or make such other arrangements, in which Borrower shall
cooperate, to receive Borrower's mail, including notifying the post office
authorities to change the address for delivery of mail addressed to Borrower to
such address as the Lender shall designate; (iii) endorse the name of Borrower
in favor of the Lender upon any and all checks, drafts, money orders, notes,
acceptances or other evidences of payment or Collateral that may come into the
Lender's possession; (iv) sign and endorse the name of Borrower on any invoice
or bill of lading relating to any of the Accounts, on verifications of Accounts
sent to any Customer, to drafts against any Customer, to assignments of
Accounts, and to notices to any Customer; and (v) do all acts and things
necessary to carry out this Agreement and the transactions contemplated hereby,
including signing the name of Borrower on any instruments required by law in
connection with the transactions contemplated hereby and on financing statements
as permitted under the Uniform Commercial Code of any appropriate state.
Borrower hereby ratifies and approves all acts of such attorneys-in-fact, and
neither the Lender nor any other such attorney-in-fact shall be liable for any
acts of commission or omission, or for any error of judgment or mistake of fact
or law of any such attorney-in-fact unless such acts are due to willful
misconduct. This power, being coupled with an interest and given to secure an
obligation, is irrevocable so long as the Revolving Loan and the Guidance Line
of Credit remain unsatisfied, or any Loan Document remains effective, as solely
determined by the Lender;

          d.  In the Lender's own name, or in the name of Borrower, demand,
collect, receive, sue for and give receipts and releases for, any and all
amounts due on Accounts, but the Lender shall not, under any circumstances, be
liable for any error or omission or delay of any kind occurring in the
settlement, collection or payment of any Accounts or any instrument received in
payment thereof or for any damage resulting therefrom unless caused by Lender's
willful misconduct;

          e.  Endorse as the agent of Borrower any chattel paper, documents or
instruments forming all or any part of the Collateral;
<PAGE>

          f.  Make formal application for the transfer of all of Borrower's
permits, licenses, approvals, agreements and the like relating to the Collateral
or to Borrower's business to the Lender or to any assignee of the Lender or to
any purchaser of any of the Collateral;

          g.  Obtain appointment of a receiver for all or any of the Collateral,
Borrower hereby consenting to the appointment of such a receiver and agreeing
not to oppose any such appointment.  Any receiver so appointed shall have such
powers as may be conferred by the appointing authority including any or all of
the powers, rights and remedies which the Lender is authorized to exercise by
the Loan Documents, and shall have the right to incur such obligations and to
issue such certificates therefor as the appointing authority shall authorize;

          h.  Take any other action which the Lender deems necessary or
desirable to protect and realize upon its security interest in the Collateral;

          i.  Borrower acknowledges that any failure to comply with its
obligation regarding the Collateral, including (without limiting the generality
of the foregoing) granting of Assignments and collection of the Accounts, shall
cause irreparable harm to the Lender for which the Lender has no adequate remedy
at law, and agrees that the Lender shall be entitled to specific performance, an
injunction or other equitable relief to enforce the Borrower's obligations under
this Agreement; and

          j.  In addition to the foregoing, and not in substitution therefor,
exercise any one or more of the rights and remedies exercisable by the Lender
under other provisions of this Agreement, under any of the other Loan Documents,
or provided by applicable law (including, without limiting the generality of the
foregoing, the Uniform Commercial Code).

     9.3  Application of Proceeds.  Any proceeds from the collection or sale or
          -----------------------
other disposition of the Collateral shall be applied in the following order of
priority:

          First, to the payment of all expenses of collecting, storing, leasing,
          -----
operating, managing, selling or disposing of the Collateral, and to the payment
of all sums which the Lender may be required or may elect to pay, if any, for
taxes, assessments, insurance and other charges upon such Collateral or any part
thereof, and of all other payments which the Lender may be required or
authorized to make under any provision of this Agreement or of any other Loan
Document (including in each such case reasonable legal costs and attorneys' fees
and expenses);

          Second, to the payment of all obligations on either the Revolving Loan
          ------
or the Guidance Line of Credit, as applicable, under this Agreement, and under
the other Loan Documents, and to the payment of any other obligations due to the
Lender, in such order as the Lender may determine in its sole discretion; and

          Third, to the payment of any surplus then remaining to Borrower,
          -----
unless otherwise provided by law or directed by a court of competent
jurisdiction; provided that Borrower shall be liable for any deficiency if the
proceeds of the Collateral are insufficient to satisfy all obligations due to
the Lender.
<PAGE>

     9.4  Collection/Enforcement Costs.  Borrower shall pay all costs and
          ----------------------------
expenses incurred by Lender in connection with the enforcement of its rights

reasonable legal costs and attorneys' fees (whether or not suit is instituted)

Agreement or any of the other Loan Documents, including without limitation, the
fees and expenses of an audit by employees or agents of the Lender, of counsel
to the Lender and with respect to any arbitration fees and costs; and (ii) pay,
and hold the Lender and each subsequent holder of the Note harmless from and
against, any and all present and future stamp taxes or similar document taxes or

<PAGE>

authorized, at any time or times without prior notice to Borrower, to set off,
appropriate and apply any and all deposits, credits, indebtedness or claims at
any time held or owing by the Lender to or for the credit or the account of

other Loan Documents may be executed in as many counterparts as may be required;

irrevocably waives, to the fullest extent permitted by law, any objection that
the Borrower may now or hereafter have to the laying of venue of any such suit,
action, or proceeding brought in any such court, or any claim that any such
suit, action, or proceeding brought in any such court has been brought in an
inconvenient forum.  Final judgment in any such suit, action, or proceeding
brought in any such court shall be conclusive and binding upon the Borrower.

upon the Borrower in any such suit, action or proceeding and (ii) shall, to the
fullest extent permitted by law, be taken and held to be valid personal service
upon and personal delivery to the Borrower. Nothing in this Section shall affect
the right of the Lender to serve process in any manner permitted by law, or
limit any right that the Lender may have to bring proceedings against the
Borrower in the courts of any jurisdiction or to enforce in any lawful manner a
judgment obtained in one jurisdiction in any other jurisdiction.

          (the "LIBOR-Based Rate").  Pricing Ratio is Funded Debt divided by Net
          Income plus Interest Expense, Taxes, Depreciation, and Amortization
          minus current period Capitalized Software Development Costs.  LIBOR
          Market Index Rate is, for any day, the annual percentage rate of
          interest equal to the London Interbank Offered Rate (rounded to the
          next higher 1/100 of 1%) for U.S. Dollar deposits for a 1-month
          maturity as reported on Telerate page 3750 as of 11:00 a.m. London
          time, for such day, provided, if such day is not a London business
          day, the immediately preceding London business day (or if not so
          reported, then as determined by Lender from another recognized source
          or interbank quotation).   Absent manifest error, the Lender's
          certificate to the Borrower stating the LIBOR-Based Rate for a
          specific day shall be conclusive upon the Borrower.

All interest payable under the terms of this Note shall be calculated on the
basis of a 360-day factor applied to the actual number of days elapsed.

     2.  Payments and Maturity.  The unpaid Principal Sum, together with
         ---------------------
interest thereon at the rate or rates provided above, shall be payable as
follows:

          a.  interest shall be due and payable monthly, commencing on the last
     day of the first calendar month commencing after the date of this Note, and

     Date").  If the Loan Agreement provides for the Borrower to make additional
     payments on account of the Principal Sum from time to time, Borrower
     promises to make those payments at the time and in the manner specified in
     the Loan Agreement.

This Note evidences Borrower's promise to repay advances and readvances under
the Loan Agreement.  This Note will continue in full force and effect and will

and evidenced by this Note may be reduced to zero from time to time.

     3.  Default Interest.  Upon the occurrence of an Event of Default (as
         ----------------
hereinafter defined), unless otherwise required by law, the Lender shall be
entitled to interest on the unpaid balance at a rate of five percent (5%) above
Lender's "Prime Rate" of interest, being that rate of interest announced by the
Lender from time to time as being its Prime Rate, in its sole discretion.

     4.  Late Charges.  If the Borrower fails to make any payment under the
         ------------
terms of this Note within ten (10) days after the date such payment is due, the
Borrower shall pay to the Lender on demand a late charge equal to five percent
(5%) of such payment.

     5.  Application and Place of Payments.    Except as otherwise provided in
         ---------------------------------
the Loan Agreement (hereinafter defined), all payments, made on account of this
Note shall be applied first to the payment of accrued and unpaid interest then
due hereunder, second to the unpaid principal balance and the remainder, if any,
shall be applied to any other amounts which remain owing hereunder.  All
payments on account of this Note shall be paid in lawful money of the United
States of America in immediately available funds during regular business hours
of the Lender at its office at 8300 Greensboro Drive, Suite 550, McLean,
Virginia 22102-3604, or at such other times and places as the Lender may at any
time and from time to time designate in writing to the Borrower.

         --------------
Revolving Line of Credit Loan Agreement and Security Agreement of even date
herewith by and between the Borrower and the Lender (the "Loan Agreement").  The
indebtedness evidenced by this Note is included within the meaning of the term
"Debt" as defined in the Loan Agreement.  The term "Loan Documents" as used in
this Note shall have the meaning ascribed to that term in the Loan
<PAGE>

Agreement. Capitalized terms used in this Note but not defined herein have the

         --------
Collateral described in the Loan Agreement.

     8.  Events of Default.  The occurrence of any one or more of the following
         -----------------
events shall constitute an event of default (individually, an "Event of Default"
and collectively, the "Events of Default") under this Note:

          a.  the failure of the Borrower to pay to the Lender when due any
     amount payable by the Borrower to the Lender under the terms of this Note;
     or

          b.  the occurrence of an event of default under any of the other Loan
     Documents.

     9.  Remedies.  Upon the occurrence of an Event of Default, at the option of
         --------
the Lender, all principal, accrued interest and other sums payable by the
Borrower to the Lender under the terms of this Note shall become immediately due
and payable, and the Lender shall have all of the rights, powers, and remedies
available under the terms of this Note, any of the other Loan Documents and all
applicable laws.  The Borrower and all endorsers hereby jointly and severally
waive presentment, protest and demand, notice of protest, notice of demand and
of dishonor and non-payment of this Note and expressly agree that this Note or
any payment hereunder may be extended from time to time without in any way

          --------
Lender all reasonable costs and expenses incurred by the Lender in connection
with the collection and enforcement of this Note, including, without limitation,

costs.

     11.  Notices.  Any notice, request, or demand to or upon the Borrower or
          -------

     12.  Miscellaneous.  Each right, power, and remedy of the Lender as
          -------------
provided for in this Note or any of the other Loan Documents, or now or
hereafter existing under any applicable law or otherwise shall be cumulative and
concurrent and shall be in addition to every other right, power, or remedy
provided for in this Note or any of the other Loan Documents or now or hereafter
existing under any applicable law, and the exercise or beginning of the exercise
by the Lender of any one or more of such rights, powers, or remedies shall not
preclude the simultaneous or later exercise by the Lender of any or all such
other rights, powers, or remedies.  No failure or delay by the Lender to insist
upon the strict performance of any term, condition, covenant, or agreement of
this Note or any of the other Loan Documents, or to exercise any
<PAGE>

right, power, or remedy consequent upon a breach thereof, shall constitute a
waiver of any such term, condition, covenant, or agreement or of any such
breach, or preclude the Lender from exercising any such right, power, or remedy
at a later time or times. By accepting payment after the due date of any amount
payable under the terms of this Note, the Lender shall not be deemed to waive
the right either to require prompt payment when due of all other amounts payable
under the terms of this Note or to declare an Event of Default for the failure
to effect such prompt payment of any such other amount. No course of dealing or
conduct shall be effective to amend, modify, waive, release, or change any
provisions of this Note. This Note may not be changed orally, but only by an
agreement in writing signed by the party against whom enforcement of any waiver,
change, modification or discharge is sought.

     13.  Partial Invalidity.  If any term or provision of this Note or the
          ------------------
application thereof to any person or circumstance shall be invalid or
unenforceable to any extent, the remainder of this Note and the application of
such term or provision to persons or circumstances other than those as to which
it is held invalid or unenforceable, shall not be affected thereby, and each
term and provision of this Note shall be valid and be enforceable to the fullest
extent permitted by law.

accelerate payment of all sums due hereunder; and (ii) to exercise all of its
rights and remedies provided in the Loan Agreement to be exercised upon the
occurrence of an Event of Default (as defined in the Loan Agreement).  In the
event that at any time this Note and any note or any other obligation to the
Lender are held by different persons, each of such persons shall have all of the
rights, privileges and options provided to the Noteholder herein and/or in the
Loan Agreement.

BANK OF AMERICA, N.A.                                           December 9, 1999

                                    GUARANTY
                                    --------

     1.  As an inducement for and in consideration of any loan(s) or other
financial accommodation(s) of even date herewith granted to Integral Systems,
Inc., a Maryland corporation (hereinafter called "Borrower"), by Bank of
America, N.A., 8300 Greensboro Drive, Suite 550, McLean, Virginia 22102-3604
(hereinafter, together with its successors and assigns, called "Lender"), the
undersigned (hereinafter called "Guarantor"), hereby unconditionally guarantees
the full and prompt payment, observance and performance when due, whether at the
stated time, by acceleration or otherwise, of all obligations of Borrower to
Lender, howsoever created, arising or evidenced, whether direct or indirect,
absolute or contingent, whether or not of the same or similar class or of like
kind to any indebtedness incurred contemporaneously with the execution of this
Guaranty, and whether now or hereafter existing, or due or to become due,
including without limitation, the following:

          a.  Any and all amounts owed by Borrower under, in connection with,
     and/or pursuant to the indebtedness evidenced by that certain Revolving
     Note of even date herewith, in the original principal sum of Nine Million
     and No/100 and No/100 Dollars ($9,000,000.00) (the "Revolving Note") and by
     that certain Guidance Line of Credit Note of even date herewith, in the
     original principal sum of Six Million and No/100 Dollars ($6,000,000.00)
     (the "Guidance Note"), both with interest thereon according to the
     provisions thereof, and all obligations of Borrower thereunder, in
     connection therewith and/or pursuant to any and all agreements and other
     documents in connection therewith; and

          b.  Any and all amounts owed by Borrower under, in connection with,
     and/or pursuant to the indebtedness evidenced by that certain Revolving
     Line of Credit Loan Agreement and Security Agreement between Borrower and
     Lender of even date herewith (the "Loan Agreement"), any and all
     obligations of Borrower thereunder, in connection therewith and/or pursuant
     to any and all agreements and other documents in connection therewith; and

          c.  All sums advanced or expenses or costs paid or incurred (including
     without limitation attorneys' fees and other legal expenses and arbitration
     fees and costs) by Lender pursuant to or in connection with the Revolving
     Note, the Guidance Note or any agreements and other documents in connection
     therewith plus applicable interest on such sums, expenses or costs; and

          d.  Any extensions, modifications, changes, substitutions,
     restatements, renewals or increases or decreases of any or all of the
     indebtedness referenced above; and

          e.  Any and all other indebtedness, obligations and liabilities of any
     kind, of Borrower to Lender, now or hereafter existing, absolute or
     contingent, joint and/or several, due or not due, secured or unsecured,
     arising by operation of law or otherwise, direct or indirect, including
     without limitation indebtedness, obligations and liabilities of

                                       1
<PAGE>

     Borrower to Lender as a member of any partnership, syndicate or association
     or other group and whether incurred by such Borrower as principal, surety,
     endorser, guarantor, accommodation party or otherwise, and any obligations
     which give rise to an equitable remedy for breach of performance if such
     breach gives rise to an obligation by such Borrower to pay Lender.

     2.  All of the obligations described in paragraph 1, above, shall be
referred to hereafter as the "Liabilities."  In the event any of the Liabilities
shall not be paid or performed according to their terms (subject to any
applicable grace or cure period), Guarantor shall immediately pay, perform or
cause the performance of the same, this Guaranty being a guarantee of full
payment and performance and not of collectibility and in no way conditional or
contingent.  This Guaranty is an absolute, unconditional and continuing
guarantee with the Guarantor being jointly and severally liable with the
Borrower and is in no way conditioned upon any requirement that Lender first
attempt to collect payment or seek performances of any of the Liabilities from
Borrower or any other borrower or guarantor, or resort to any other security or
other means of obtaining payment or performance of any of the Liabilities, or
upon any other contingency whatsoever.

     3.  Guarantor further agrees to pay all expenses (including reasonable
attorneys' fees and expenses and arbitration fees and costs) paid or incurred by
Lender in endeavoring to collect the Liabilities, or any part thereof, and in
enforcing or defending this Guaranty, whether or not a lawsuit is commenced.

     4.  Guarantor represents and warrants that Guarantor is either financially
interested in Borrower or will receive other material economic benefits as a
result of any loan(s), leases(s) or other financial accommodation(s) made or
granted to Borrower by Lender from time to time.  Guarantor further represents
and warrants that Guarantor is willing to enter into this Guaranty as a material
inducement to Lender to extend loan(s) or other financial accommodation(s), or
to enter into lease(s), from time to time with Borrower, and acknowledges that
Lender would not be willing to extend any such loan(s) or other financial
accommodation(s) or enter into such lease(s) absent this Guaranty.

     5.  Guarantor agrees that the occurrence of any of the following events
shall constitute a default under this Guaranty:  (a) the failure of any
Guarantor to perform or observe any obligation under this Guaranty, or (b) the
dissolution or insolvency of Borrower, or (c) the inability of Borrower to pay
debts generally as they mature, or (d) an assignment by Borrower of any of the
Liabilities for the benefit of creditors, or (e) the institution of any
proceeding by or against Borrower (under the Bankruptcy Code or otherwise)
seeking to adjudicate Borrower bankrupt or insolvent, or seeking reorganization,
arrangement, adjustment or composition of it or its debts under any law relating
to bankruptcy, insolvency or reorganization or relief of debtors or seeking the
appointment of a receiver, trustee or custodian for itself or for all or a
substantial part of its property, which proceeding (unless instituted by
Borrower) is not dismissed within thirty (30) days thereafter, or (f) the
default by Borrower under any agreement or document concerning or relating to
the Liabilities, or (g) any representation or warranty contained herein or in
any other document delivered by or on behalf Borrower to Lender shall be false
or misleading in any material respect, or (h) there shall be a default or event
of default under any other

                                       2
<PAGE>

agreement or document securing or guaranteeing any of the obligations secured by
this Guaranty, or (i) there shall be a default or event of default under any
indebtedness or obligation of Borrower to any third party that causes that third
party to declare such indebtedness or other obligation due prior to its
scheduled date of maturity. Upon and after the occurrence of a default
hereunder, the Liabilities shall be automatically accelerated and shall become
immediately due and payable by Guarantor, or Guarantor's successor or estate,
without presentment, demand, protest, or further notice of any kind, all of
which are hereby expressly waived by Guarantor.

     6.  Guarantor further agrees that this Guaranty shall continue to be
effective or shall be reinstated, as the case may be, if at any time payment to
or for the benefit of Lender of the Liabilities, or any part thereof, is
rescinded or must otherwise be returned by Lender due to the insolvency,
bankruptcy or reorganization of Borrower or otherwise, all as though such
payment to or for the benefit of Lender had not been made.

     7.  Lender may, without demand or notice of any kind, at any time when any
amount shall be due and payable hereunder by Guarantor, appropriate and apply
toward the payment of such amount, and in such order of application as Lender
may from time to time elect, any property, balances, credits, deposits,
accounts, instruments or moneys of Guarantor in the possession or control of
Lender for any purpose.

     8.  This Guaranty shall be a continuing, absolute and unconditional
guaranty of payment and performance and not of collectibility and shall remain
in full force and effect as to Guarantor, subject to discontinuance only as
follows:  Guarantor, or any person duly authorized and acting on behalf of
Guarantor, may give written notice to Lender of discontinuance of this Guaranty,
but no such notice shall be effective in any respect until it is actually
received by Lender and no such notice shall affect or impair the obligations
hereunder of Guarantor with respect to any Liabilities existing at the date of
receipt of such notice by Lender (or any Liabilities required or permitted to be
advanced by Lender on or after such date), or for renewals or extensions of such
Liabilities made after Lender receives Guarantor's notice, or any interest
thereon or any expenses paid or incurred by Lender in endeavoring to collect
such Liabilities, or any part thereof, or in enforcing this Guaranty against
Guarantor.  Any such notice of discontinuance by or on behalf of any Guarantor
shall not affect, impair or release the obligations hereunder of any other
guarantor with respect to any of the Liabilities.

     9.  Lender may at any time and from time to time, without the consent of,
or notice to, Guarantor, and without affecting, impairing or releasing the
obligations of Guarantor hereunder, do any or all of the following:  (a) retain
or obtain a security interest in any property to secure any of the Liabilities
or any obligations hereunder, (b) retain or obtain the primary or secondary
liability of any party or parties, in addition to Guarantor, with respect to any
of the Liabilities, (c) renew, extend (including extensions beyond the original
term), modify, alter, change the interest rate of, release or discharge any of
the Liabilities, (d) settle, release or compromise any liability of the Borrower
or of any of the Liabilities or any liability of any nature of any other party
or parties with respect to the Liabilities or any security therefor, (e) accept
partial payments of the Liabilities, (f) settle, release (by operation of law or
otherwise), compound, compromise, collect or liquidate any of the Liabilities
and any property securing any of the Liabilities, (g) consent to the transfer of
any property securing any of the Liabilities, (h)

                                       3
<PAGE>

resort to Guarantor for payment of any of the Liabilities, whether or not Lender
shall have resorted to any property securing any of the Liabilities or any
obligation hereunder or shall have proceeded against any other guarantor or any
other party primarily or secondarily liable on any of the Liabilities, (i) make
any other changes in its agreements with Borrower, and (j) stop lending money or
extending other credit to Borrower.

     10.  Any amount received by Lender from whatsoever source and applied by it
to the payment of the Liabilities may be applied in such order of application as
Lender may from time to time elect.

     11.  Guarantor is now adequately informed of Borrower's financial
condition, and Guarantor agrees to keep so informed.  Guarantor agrees that
Lender has no obligation to provide Guarantor with any present or future
information concerning the financial condition of Borrower.  Guarantor has not
relied on financial information furnished by Lender in deciding to execute this
Guaranty.

     12.  Guarantor hereby agrees that any debt of Borrower to Guarantor is
expressly subordinate to the right of Lender to payment of the Liabilities, and
that Lender shall be entitled to full payment of all of the Liabilities prior to
the exercise by Guarantor of any rights to payment or performance of any debt
which the Borrower may owe Guarantor.  Guarantor assigns to Lender all rights
Guarantor may have in any proceeding under the Federal Bankruptcy Code or any
receivership or insolvency proceeding of Borrower, including all rights of
Guarantor to be paid by Borrower.  This assignment does not prevent Lender from
enforcing Guarantor's obligations hereunder in any way.  To the extent permitted
by law, any payments or other property at any time received by Guarantor from
the Borrower in respect of any indebtedness of Borrower to Guarantor shall be
held in trust for and shall be paid or transferred to Lender upon demand.

     13.  Guarantor hereby expressly waives: (a) notice of the acceptance of
this Guaranty, (b) notice of the existence or creation of all or any of the
Liabilities, (c) presentment, demand, notice of dishonor, protest, and all other
notices whatsoever, (d) all diligence in collection or protection of or
realization upon the Liabilities or any part thereof, any obligation hereunder,
or any security for any of the foregoing, (e) all defenses based on suretyship
or impairment of collateral, and (f) all events and circumstances which might
otherwise constitute a defense or discharge of the obligations of Borrower,
Guarantor or any other guarantor.  Guarantor shall not be released or
discharged, either in whole or in part, by Lender's failure to perfect, delay in
perfection or failure to continue the perfection of any security interest in any
property that secures any of the Liabilities or any obligation of Guarantor
hereunder, or to protect the property covered by any such security interest.
Guarantor further waives, to the extent permitted by law, (i) the benefits of
Sections 49-25 and 49-26 of the Code of Virginia (1950), as amended, and any
amendments thereto or any similar statutes or rules of law and (ii) the benefit
of any homestead or similar exemption, state or federal, with respect to the
obligations covered by this Guaranty.

     14.  The Lender shall have the right to set-off, at any time without notice
to the Guarantor, any and all deposits or other sums at any time or times
credited by or due from the

                                       4
<PAGE>

Lender to the Guarantor (whether or not matured) against the obligations of the
Guarantor hereunder.

     15.  Lender may, without notice to Guarantor or Borrower of any kind, sell,
assign, or transfer all or any of the Liabilities, and in such event each and
every immediate and successive assignee, transferee, or holder of all or any of
the Liabilities shall have the right to enforce this Guaranty, by suit or
otherwise, for the benefit of such assignee, transferee, or holder, as fully as
if such assignee, transferee or holder were herein by name specifically given
such rights, powers and benefits.  Lender shall have an unimpaired right, prior
and superior to that of any such assignee, transferee or holder, to enforce this
Guaranty for the benefit of Lender as to so much of the Liabilities as it has
not sold, assigned, or transferred.

     16.  No delay on the part of Lender in the exercise of any right or remedy
shall operate as a waiver thereof, and no single or partial exercise by Lender
of any right or remedy shall preclude other or further exercise thereof or the
exercise of any other right or remedy.

     17.  No action of Lender permitted hereunder shall in any way affect,
impair or release this Guaranty.

     18.  Representations and Warranties of Guarantor.  To induce Lender to make
          -------------------------------------------
the loans evidenced by the Revolving Note and by the Guidance Note, Guarantor
makes the following representations and warranties, upon each of which Lender,
its successors, and assigns are entitled to rely and have relied,
notwithstanding any investigation heretofore or hereafter made by Lender and
such successors and assigns.  All such representations and warranties are true
and complete in all respects and do not omit any material fact necessary to make
such representations and warranties not misleading.

          (a) No Conflicts or Defaults.  The execution and delivery of this
              ------------------------
Guaranty and the performance by the Guarantor of the Guarantor's obligations
hereunder will not conflict with or violate, or constitute a default or require
any consent or waiver under, any provision of any mortgage, deed of trust,
evidence of indebtedness, order, decree or agreement to which the Guarantor is a
party or for which the Guarantor or any part of the Guarantor's property is
bound.

          (b) Enforceability.  This Guaranty is a legal, valid and binding
              --------------
obligation of the Guarantor, enforceable against the Guarantor in accordance
with its terms, except as limited by bankruptcy, insolvency and other laws
affecting the rights of creditors generally and general principles of equity.

          (c) Litigation; Violations of Law.  There are no actions, suits or
              -----------------------------
proceedings of a material nature of which Guarantor has knowledge pending or
overtly threatened against or affecting the Guarantor, and to Guarantor's
knowledge no event has occurred (including, without limitation, the execution,
acknowledgment and delivery of this Guaranty and the consummation of the
transactions contemplated hereby) which will violate, be in conflict with,
result in the breach of or constitute (with or without notice or the passage of
time, or both) a default under any judicial decision, statute, ruling,
direction, rule, regulation, permit, certificate or ordinance of any
governmental authority in any way applicable to the Guarantor.  The Guarantor is
not in

                                       5
<PAGE>

default with respect to any judgment, order, writ, injunction, decree or demand
of any court, arbitrator, administrative agency or other governmental or quasi-
governmental authority.

          (d) Financial Information.  All financial information furnished to

                                    GUARANTY
                                    --------

     1.  As an inducement for and in consideration of any loan(s) or other
financial accommodation(s) of even date herewith granted to Integral Systems,
Inc., a Maryland corporation (hereinafter called "Borrower"), by Bank of
America, N.A., 8300 Greensboro Drive, Suite 550, McLean, Virginia 22102-3604
(hereinafter, together with its successors and assigns, called "Lender"), the
undersigned (hereinafter called "Guarantor"), hereby unconditionally guarantees
the full and prompt payment, observance and performance when due, whether at the
stated time, by acceleration or otherwise, of all obligations of Borrower to
Lender, howsoever created, arising or evidenced, whether direct or indirect,
absolute or contingent, whether or not of the same or similar class or of like
kind to any indebtedness incurred contemporaneously with the execution of this
Guaranty, and whether now or hereafter existing, or due or to become due,
including without limitation, the following:

          a.  Any and all amounts owed by Borrower under, in connection with,
     and/or pursuant to the indebtedness evidenced by that certain Revolving
     Note of even date herewith, in the original principal sum of Nine Million
     and No/100 and No/100 Dollars ($9,000,000.00) (the "Revolving Note") and by
     that certain Guidance Line of Credit Note of even date herewith, in the
     original principal sum of Six Million and No/100 Dollars ($6,000,000.00)
     (the "Guidance Note"), both with interest thereon according to the
     provisions thereof, and all obligations of Borrower thereunder, in
     connection therewith and/or pursuant to any and all agreements and other
     documents in connection therewith; and

          b.  Any and all amounts owed by Borrower under, in connection with,
     and/or pursuant to the indebtedness evidenced by that certain Revolving
     Line of Credit Loan Agreement and Security Agreement between Borrower and
     Lender of even date herewith (the "Loan Agreement"), any and all
     obligations of Borrower thereunder, in connection therewith and/or pursuant
     to any and all agreements and other documents in connection therewith; and

          c.  All sums advanced or expenses or costs paid or incurred (including
     without limitation attorneys' fees and other legal expenses and arbitration
     fees and costs) by Lender pursuant to or in connection with the Revolving
     Note, the Guidance Note or any agreements and other documents in connection
     therewith plus applicable interest on such sums, expenses or costs; and

          d.  Any extensions, modifications, changes, substitutions,
     restatements, renewals or increases or decreases of any or all of the
     indebtedness referenced above; and

          e.  Any and all other indebtedness, obligations and liabilities of any
     kind, of Borrower to Lender, now or hereafter existing, absolute or
     contingent, joint and/or several, due or not due, secured or unsecured,
     arising by operation of law or otherwise,

                                       1
<PAGE>

     direct or indirect, including without limitation indebtedness, obligations
     and liabilities of Borrower to Lender as a member of any partnership,
     syndicate or association or other group and whether incurred by such
     Borrower as principal, surety, endorser, guarantor, accommodation party or
     otherwise, and any obligations which give rise to an equitable remedy for
     breach of performance if such breach gives rise to an obligation by such
     Borrower to pay Lender.

     2.  All of the obligations described in paragraph 1, above, shall be
referred to hereafter as the "Liabilities."  In the event any of the Liabilities
shall not be paid or performed according to their terms (subject to any
applicable grace or cure period), Guarantor shall immediately pay, perform or
cause the performance of the same, this Guaranty being a guarantee of full
payment and performance and not of collectibility and in no way conditional or
contingent.  This Guaranty is an absolute, unconditional and continuing
guarantee with the Guarantor being jointly and severally liable with the
Borrower and is in no way conditioned upon any requirement that Lender first
attempt to collect payment or seek performances of any of the Liabilities from
Borrower or any other borrower or guarantor, or resort to any other security or
other means of obtaining payment or performance of any of the Liabilities, or
upon any other contingency whatsoever.

     3.  Guarantor further agrees to pay all expenses (including reasonable
attorneys' fees and expenses and arbitration fees and costs) paid or incurred by
Lender in endeavoring to collect the Liabilities, or any part thereof, and in
enforcing or defending this Guaranty, whether or not a lawsuit is commenced.

     4.  Guarantor represents and warrants that Guarantor is either financially
interested in Borrower or will receive other material economic benefits as a
result of any loan(s), leases(s) or other financial accommodation(s) made or
granted to Borrower by Lender from time to time.  Guarantor further represents
and warrants that Guarantor is willing to enter into this Guaranty as a material
inducement to Lender to extend loan(s) or other financial accommodation(s), or
to enter into lease(s), from time to time with Borrower, and acknowledges that
Lender would not be willing to extend any such loan(s) or other financial
accommodation(s) or enter into such lease(s) absent this Guaranty.

     5.  Guarantor agrees that the occurrence of any of the following events
shall constitute a default under this Guaranty:  (a) the failure of any
Guarantor to perform or observe any obligation under this Guaranty, or (b) the
dissolution or insolvency of Borrower, or (c) the inability of Borrower to pay
debts generally as they mature, or (d) an assignment by Borrower of any of the
Liabilities for the benefit of creditors, or (e) the institution of any
proceeding by or against Borrower (under the Bankruptcy Code or otherwise)
seeking to adjudicate Borrower bankrupt or insolvent, or seeking reorganization,
arrangement, adjustment or composition of it or its debts under any law relating
to bankruptcy, insolvency or reorganization or relief of debtors or seeking the
appointment of a receiver, trustee or custodian for itself or for all or a
substantial part of its property, which proceeding (unless instituted by
Borrower) is not dismissed within thirty (30) days thereafter, or (f) the
default by Borrower under any agreement or document concerning or relating to
the Liabilities, or (g) any representation or warranty contained herein or in
any other document delivered by or on behalf Borrower to Lender shall be false
or misleading

                                       2
<PAGE>

in any material respect, or (h) there shall be a default or event of default
under any other agreement or document securing or guaranteeing any of the
obligations secured by this Guaranty, or (i) there shall be a default or event
of default under any indebtedness or obligation of Borrower to any third party
that causes that third party to declare such indebtedness or other obligation
due prior to its scheduled date of maturity. Upon and after the occurrence of a
default hereunder, the Liabilities shall be automatically accelerated and shall
become immediately due and payable by Guarantor, or Guarantor's successor or
estate, without presentment, demand, protest, or further notice of any kind, all
of which are hereby expressly waived by Guarantor.

     6.  Guarantor further agrees that this Guaranty shall continue to be
effective or shall be reinstated, as the case may be, if at any time payment to
or for the benefit of Lender of the Liabilities, or any part thereof, is
rescinded or must otherwise be returned by Lender due to the insolvency,
bankruptcy or reorganization of Borrower or otherwise, all as though such
payment to or for the benefit of Lender had not been made.

     7.  Lender may, without demand or notice of any kind, at any time when any
amount shall be due and payable hereunder by Guarantor, appropriate and apply
toward the payment of such amount, and in such order of application as Lender
may from time to time elect, any property, balances, credits, deposits,
accounts, instruments or moneys of Guarantor in the possession or control of
Lender for any purpose.

     8.  This Guaranty shall be a continuing, absolute and unconditional
guaranty of payment and performance and not of collectibility and shall remain
in full force and effect as to Guarantor, subject to discontinuance only as
follows:  Guarantor, or any person duly authorized and acting on behalf of
Guarantor, may give written notice to Lender of discontinuance of this Guaranty,
but no such notice shall be effective in any respect until it is actually
received by Lender and no such notice shall affect or impair the obligations
hereunder of Guarantor with respect to any Liabilities existing at the date of
receipt of such notice by Lender (or any Liabilities required or permitted to be
advanced by Lender on or after such date), or for renewals or extensions of such
Liabilities made after Lender receives Guarantor's notice, or any interest
thereon or any expenses paid or incurred by Lender in endeavoring to collect
such Liabilities, or any part thereof, or in enforcing this Guaranty against
Guarantor.  Any such notice of discontinuance by or on behalf of any Guarantor
shall not affect, impair or release the obligations hereunder of any other
guarantor with respect to any of the Liabilities.

     9.  Lender may at any time and from time to time, without the consent of,
or notice to, Guarantor, and without affecting, impairing or releasing the
obligations of Guarantor hereunder, do any or all of the following:  (a) retain
or obtain a security interest in any property to secure any of the Liabilities
or any obligations hereunder, (b) retain or obtain the primary or secondary
liability of any party or parties, in addition to Guarantor, with respect to any
of the Liabilities, (c) renew, extend (including extensions beyond the original
term), modify, alter, change the interest rate of, release or discharge any of
the Liabilities, (d) settle, release or compromise any liability of the Borrower
or of any of the Liabilities or any liability of any nature of any other party
or parties with respect to the Liabilities or any security therefor, (e) accept
partial payments of the Liabilities, (f) settle, release (by operation of law or
otherwise), compound, compromise, collect or liquidate any of the Liabilities
and any property securing any

                                       3
<PAGE>

of the Liabilities, (g) consent to the transfer of any property securing any of
the Liabilities, (h) resort to Guarantor for payment of any of the Liabilities,
whether or not Lender shall have resorted to any property securing any of the
Liabilities or any obligation hereunder or shall have proceeded against any
other guarantor or any other party primarily or secondarily liable on any of the
Liabilities, (i) make any other changes in its agreements with Borrower, and (j)
stop lending money or extending other credit to Borrower.

     10.  Any amount received by Lender from whatsoever source and applied by it
to the payment of the Liabilities may be applied in such order of application as
Lender may from time to time elect.

     11.  Guarantor is now adequately informed of Borrower's financial
condition, and Guarantor agrees to keep so informed.  Guarantor agrees that
Lender has no obligation to provide Guarantor with any present or future
information concerning the financial condition of Borrower.  Guarantor has not
relied on financial information furnished by Lender in deciding to execute this
Guaranty.

     12.  Guarantor hereby agrees that any debt of Borrower to Guarantor is
expressly subordinate to the right of Lender to payment of the Liabilities, and
that Lender shall be entitled to full payment of all of the Liabilities prior to
the exercise by Guarantor of any rights to payment or performance of any debt
which the Borrower may owe Guarantor.  Guarantor assigns to Lender all rights
Guarantor may have in any proceeding under the Federal Bankruptcy Code or any
receivership or insolvency proceeding of Borrower, including all rights of
Guarantor to be paid by Borrower.  This assignment does not prevent Lender from
enforcing Guarantor's obligations hereunder in any way.  To the extent permitted
by law, any payments or other property at any time received by Guarantor from
the Borrower in respect of any indebtedness of Borrower to Guarantor shall be
held in trust for and shall be paid or transferred to Lender upon demand.

     13.  Guarantor hereby expressly waives: (a) notice of the acceptance of
this Guaranty, (b) notice of the existence or creation of all or any of the
Liabilities, (c) presentment, demand, notice of dishonor, protest, and all other
notices whatsoever, (d) all diligence in collection or protection of or
realization upon the Liabilities or any part thereof, any obligation hereunder,
or any security for any of the foregoing, (e) all defenses based on suretyship
or impairment of collateral, and (f) all events and circumstances which might
otherwise constitute a defense or discharge of the obligations of Borrower,
Guarantor or any other guarantor.  Guarantor shall not be released or
discharged, either in whole or in part, by Lender's failure to perfect, delay in
perfection or failure to continue the perfection of any security interest in any
property that secures any of the Liabilities or any obligation of Guarantor
hereunder, or to protect the property covered by any such security interest.
Guarantor further waives, to the extent permitted by law, (i) the benefits of
Sections 49-25 and 49-26 of the Code of Virginia (1950), as amended, and any
amendments thereto or any similar statutes or rules of law and (ii) the benefit
of any homestead or similar exemption, state or federal, with respect to the
obligations covered by this Guaranty.

     14.  The Lender shall have the right to set-off, at any time without notice
to the Guarantor, any and all deposits or other sums at any time or times
credited by or due from the

                                       4
<PAGE>

Lender to the Guarantor (whether or not matured) against the obligations of the
Guarantor hereunder.

     15.  Lender may, without notice to Guarantor or Borrower of any kind, sell,
assign, or transfer all or any of the Liabilities, and in such event each and
every immediate and successive assignee, transferee, or holder of all or any of
the Liabilities shall have the right to enforce this Guaranty, by suit or
otherwise, for the benefit of such assignee, transferee, or holder, as fully as
if such assignee, transferee or holder were herein by name specifically given
such rights, powers and benefits.  Lender shall have an unimpaired right, prior
and superior to that of any such assignee, transferee or holder, to enforce this
Guaranty for the benefit of Lender as to so much of the Liabilities as it has
not sold, assigned, or transferred.

     16.  No delay on the part of Lender in the exercise of any right or remedy
shall operate as a waiver thereof, and no single or partial exercise by Lender
of any right or remedy shall preclude other or further exercise thereof or the
exercise of any other right or remedy.

     17.  No action of Lender permitted hereunder shall in any way affect,
impair or release this Guaranty.

     18.  Representations and Warranties of Guarantor.  To induce Lender to make
          -------------------------------------------
the loans evidenced by the Revolving Note and by the Guidance Note, Guarantor
makes the following representations and warranties, upon each of which Lender,
its successors, and assigns are entitled to rely and have relied,
notwithstanding any investigation heretofore or hereafter made by Lender and
such successors and assigns.  All such representations and warranties are true
and complete in all respects and do not omit any material fact necessary to make
such representations and warranties not misleading.

          (a) No Conflicts or Defaults.  The execution and delivery of this
              ------------------------
Guaranty and the performance by the Guarantor of the Guarantor's obligations
hereunder will not conflict with or violate, or constitute a default or require
any consent or waiver under, any provision of any mortgage, deed of trust,
evidence of indebtedness, order, decree or agreement to which the Guarantor is a
party or for which the Guarantor or any part of the Guarantor's property is
bound.

          (b) Enforceability.  This Guaranty is a legal, valid and binding
              --------------

with its terms, except as limited by bankruptcy, insolvency and other laws
affecting the rights of creditors generally and general principles of equity.

          (c) Litigation; Violations of Law.  There are no actions, suits or
              -----------------------------
proceedings of a material nature of which Guarantor has knowledge pending or
overtly threatened against or affecting the Guarantor, and to Guarantor's
knowledge no event has occurred (including, without limitation, the execution,
acknowledgment and delivery of this Guaranty and the consummation of the
transactions contemplated hereby) which will violate, be in conflict with,
result in the breach of or constitute (with or without notice or the passage of
time, or both) a default under any judicial decision, statute, ruling,
direction, rule, regulation, permit, certificate or ordinance of any
governmental authority in any way applicable to the Guarantor.  The Guarantor is
not in

                                       5
<PAGE>

default with respect to any judgment, order, writ, injunction, decree or demand
of any court, arbitrator, administrative agency or other governmental or quasi-
governmental authority.

          (d) Financial Information.  All financial information furnished to
              ---------------------

accurately presents such Guarantor's financial condition in all material
respects as of the dates thereof, and no material adverse change has occurred in
the financial condition reflected therein since the dates thereof.

          (e) Insolvency Matters.  No bankruptcy, reorganization, arrangement,
              ------------------
readjustment of debt, insolvency or other proceeding has been commenced or
threatened by or against the Guarantor, or consented to or acquiesced in by the

of Operating Costs with respect to the 5200 Building.  Notwithstanding any
provision of the Original Lease, the First Amendment, or this Second Amendment
to the contrary:

          a.   "Project Operating Costs" shall also include any and all
obligations of Landlord to any neighboring or other property owner for the

<PAGE>

replacement, operation, and/or management of any roadways, parking areas,
landscaped areas, water, sanitary sewer, storm drainage, or other site
improvement or facilities which may be in common between the Project and the
property owned by such neighboring or other property owner; and

          b.   In the event that any expense relating to the exterior or common
areas of the Project benefits only a portion of the Project, which portion
includes the Building, Landlord may, at Landlord's option, equitably adjust such
expense to reflect the portion of the Project so benefited.

          c.   In the event that any expense relating to the exterior of the
Building or common areas of the Building, if any, benefits only a portion of the
Building, which portion includes the Leased Premises, Landlord may, at
Landlord's option, equitably adjust such expense to reflect the portion of the
Building so benefited.

     7.   Construction Conditions.
          -----------------------

          a.   The leasehold improvements with respect to the Expansion Premises
(the "Improvements") shall be constructed in accordance with Schedule 3-B
hereof.  If any act, omission or change requested or caused by Tenant increases
the cost of work or materials or the time required for completion of
construction, Tenant shall reimburse Landlord for such increase in cost at the
time the increased cost is incurred and shall reimburse Landlord for any loss in
Rent at the time the Rent would have become due.  Landlord's approval of
Tenant's plans for Improvements shall create no responsibility or liability on
the part of Landlord for their completeness, design sufficiency, or compliance
with laws, rules and regulations of governmental agencies or authorities.

          b.   Tenant acknowledges that, except as expressly set forth in
Schedule 3-B hereof, it has inspected and accepts the 5000 Building, the 5200
Building, the Original Premises, and the Expansion Premises in their present,
"as-is" condition, in the configuration described in Schedule 1 of the Original
Lease and Schedule 1-B hereof, and as suitable for the purpose for which the
Original Premises and the Expansion Premises are leased.  Tenant further
acknowledges that no representations as to the repair of the Original Premises
or the Expansion Premises, nor promises to alter, remodel or improve the
Original Premises or the Expansion Premises have been made by Landlord, unless
such are expressly set forth in Schedule 3 of the Original Lease or Schedule 3-B
hereof.

          c.   Notwithstanding any provision of the Original Lease, the First
Amendment, or this Second Amendment to the contrary, in the event that a
building, zoning, fire, or other governmental law, ordinance, regulation, or
rule is enacted or otherwise becomes applicable to the Leased Premises after the
date hereof (regardless of the cause thereof or the reason therefor) and such
law, ordinance, regulation, or rule requires that alterations or improvements be
made to the Leased Premises in order to comply therewith, Tenant shall, at
Tenant's expense and subject to Paragraph 11 of the Original Lease, make such
alterations or improvements as may be required by such law, ordinance,
regulation, or rule, in which event Landlord's approval thereof shall not be
unreasonably withheld, conditioned, or delayed.

     8.   Insurance.
          ---------

          a.   With respect to the fire insurance required under Paragraph
7(A)(1) of the Original Lease to be secured and maintained by Landlord
throughout the Lease Term and notwithstanding any provision of such paragraph to
the contrary, Landlord shall only be required to secure and maintain fire
insurance with extended coverage endorsements attached in an amount sufficient
for Landlord to not be deemed a co-insurer of the Building.

          b.   Notwithstanding any provision of Paragraph 8 of the Original
Lease to the contrary, Tenant and Landlord release each other and waive any
right of recovery against each other for loss or damage to the waiving party's
property which occurs in or about the Leased Premises or the Building, whether
due to the negligence of either party, their agents, employees, officers,
contractors, licensees, invitees or otherwise, to the extent that such loss or
damage would be covered by the fire and extended coverage insurance policies
required to be maintained by the waiving party hereunder.  Tenant and Landlord
agree that all policies of insurance obtained by either of them in connection
with the Leased Premises shall contain appropriate waiver of subrogation
clauses.

     9.   Subordination and Attornment.  The text of Paragraph 38 of the
          ----------------------------
Original Lease is hereby deleted in its entirety, and the following is hereby
inserted in place thereof:

     "Tenant acknowledges that this Lease is subject and subordinate to all
     leases in which Landlord is lessee and to any mortgage or deed of trust now
     in force against the Building and to all advances made or hereafter to be
     made thereunder, or any amendments or modifications thereof.  Tenant also
     agrees that this Lease shall be subject and subordinate to any future
     leases in which Landlord is lessee and to any future first mortgage or deed
     of trust hereafter in force against the Building and to all advances made
     or hereafter to be made thereunder, or any amendments or modifications
     thereof (all such existing and future leases, mortgages and deeds of trust
     referred to collectively as "Superior Instruments"). Tenant also agrees
     that if the holder of any Superior Instrument elects to have this Lease
     superior to its Superior Instrument and gives notice of its election to
     Tenant, then this Lease shall be superior to the lien of any such lease,
     mortgage or deed of trust and all renewals, replacements and extensions
     thereof, whether this Lease is dated before or after such lease, mortgage
     or deed of trust. If requested in writing by Landlord or any first
     mortgagee or ground lessor of Landlord, Tenant agrees to execute a
     subordination agreement required to further effect the provisions of this
     paragraph.

     "In the event of (a) any transfer of the Building in lieu of foreclosure
     or, (b) the termination of a lease for the Building in which Landlord is
     lessee or, (c) the foreclosure of any Superior Instrument, or (d) a sale of
     the Building pursuant to any Superior Instrument, Tenant shall attorn to
     such purchaser, transferee or, lessor, or purchaser and shall recognize
     such party as landlord under this Lease, provided such party acquires and
     accepts the Leased Premises subject to this
<PAGE>

     Lease. The agreement of Tenant to attorn contained in the immediately
     preceding sentence shall survive any such foreclosure sale or transfer."

     10.  Roof Antennae.
          -------------

          a.   Subject to (i) compliance with all rules, regulations, statutes,
and codes of any governmental authority having jurisdiction thereover and (ii)
compliance with any covenants, conditions, and restrictions applicable to the
Building and/or the Project, Tenant shall have (A) the exclusive right to
install, at any time after the date hereof, upon the roof of the 5000 Building
an Orbitron Model SX-12 mesh antennae for Tenant's exclusive use (the
"Antennae") and (B) the non-exclusive right, at any time and from time to time
thereafter, to maintain and repair the Antennae, including the non-exclusive
right to access the Antennae for maintenance and repair purposes; provided that
such maintenance, repair, and/or access does not void any roof or other warranty
applicable to the 5000 Building.  Subject to Paragraph 10(e) hereof and for
purposes of this Paragraph 10, Tenant accepts the roof of the 5000 Building in
its condition as of the date hereof.

          b.   Tenant shall obtain any and all licenses, approvals, permits,
etc. which are necessary for the installation, maintenance, repair, and/or use
of the Antennae and that its use thereof shall not in any way conflict with any
applicable law, statute, ordinance, or governmental rules or regulation now in
force or which may hereafter be enacted.  Tenant further agrees that it will, at
its sole cost and expense, promptly comply or ensure that the 5000 Building
complies with all laws, statutes, ordinances, governmental rules or regulations,
or requirements of any board of fire insurance underwriters or similar bodies
now or hereafter constituted, which laws, statutes, ordinances, rules,
regulations, or requirements relate to or affect Tenant's use, maintenance,
and/or repair of the Antennae.  In addition, Tenant shall indemnify and hold
Landlord harmless from and against any and all loss, cost, damage, or liability
(including any attorney's fees incurred in defending Landlord with respect
thereto) arising out of any violations of said laws, statutes, ordinances,
rules, regulations, or requirements by Tenant or with respect to any personal
injury and/or property damage arising out of the installation, inspection,
adjustment, maintenance, repair, and/or removal of the Antennae.  If the premium
payable with respect to any insurance policy carried by Landlord is increased as
a result of the presence of or Tenant's use, maintenance, and/or repair of the
Antennae, Tenant shall pay such premium increase to Landlord as additional rent
within thirty (30) days after Landlord's demand therefore.

          c.   Tenant shall, at its sole expense, maintain and repair the
Antennae and, from time to time as necessary, promptly repair any and all damage
to the roof and/or any other component of the 5000 Building or the Project which
may be attributable to such maintenance and/or repair.  Tenant's rights
hereunder shall be exercised so as to not (i) create any hazardous condition or
interfere with or impair the operation of the heating, ventilation, air
conditioning, plumbing, electrical, fire protection, life safety, public
utilities, and/or other systems or facilities within the 5000 Building or the
Project or (ii) directly or indirectly interfere with, delay, restrict, or
impose any expense, work, or other obligation upon Landlord in the maintenance,
repair, and/or operation of the 5000 Building.  In addition, the Antennae shall
be used by Tenant solely in the ordinary course of Tenant's business operations,
and Tenant shall not, directly or
<PAGE>

indirectly, sublease, license, or otherwise permit any third party to use the
Antennae for any purpose whatsoever.

          d.   At any time after the date hereof and provided that an Event of
Default is not then continuing under the Amended Lease, Tenant shall have the
right to remove the Antennae from the roof of the Building.  Upon the expiration
or sooner termination of the Lease, Tenant shall remove the Antennae from the
roof of the Building, which removal shall be at Landlord's option in the event
that an Event of Default is then continuing under the Lease.  Any removal of the
Antennae shall be at Tenant's sole cost and expense and shall include the repair
of any damage caused thereby to the 5000 Building (including the roof thereof)
or other improvements to the land on which the 5000 Building is located, and any
removal of the Antennae, except for a temporary removal for the purpose of
repair, any such removal shall include the removal of any ancillary equipment or
structures, including without limitation any concrete slab and any electrical
cables.  Upon any such removal in accordance herewith, the Antennae shall be
deemed to be the personal property of Tenant for all purposes hereof.

          e.   Tenant hereby agrees that prior to the installation of the
Antennae upon the roof of the 5000 Building, Tenant shall make certain
structural alterations to the steel beams and joists supporting the roof of the
5000 Building, which structural alterations are necessary to support the
Antennae and are more particularly described in those certain structural
drawings entitled "Integral Systems Roof Top Dish Support Framing, Plans,
Section and Notes" and "Integral Systems, Roof Reinf." and prepared by ET&A
Consulting, Inc, a copy of which structural drawings have been delivered by
Landlord to Tenant.  Such structural alterations shall be deemed "alterations"
for all purposes of the Lease, including without limitation Paragraph 11 of the
Original Lease, and notwithstanding any provision of such paragraph to the
contrary, Landlord hereby consents to such structural alterations subject to all
applicable provisions of the Lease, which consent shall not be deemed or
otherwise construed as Landlord's consent to any additional or other alterations
to the structure of the roof of the 5000 Building or otherwise.

     11.  Limitation of Landlord's Liability.  The obligations of Landlord under
          ----------------------------------
the Lease do not constitute personal obligations of the individual members,
partners, shareholders, directors, officers, employees, or agents of Landlord,
and Tenant shall look solely to Landlord's interest in the Building and to no
other assets of Landlord for satisfaction of any liability in respect of the
Lease.  Tenant hereby agrees that it will not seek recourse against the
individual members, partners, shareholders, directors, officers, employees, or
agents of Landlord or any of their personal assets for such satisfaction.
Notwithstanding any provision of the Original Lease, the First Amendment, or
this Second Amendment to the contrary, Landlord shall not be liable to Tenant or
its employees, agents, or contractors for any consequential damages or damages
for loss of profits.

     12.  Severability.  The parties intend this Second Amendment, the First
          ------------
Amendment, and the Original Lease to be legally valid and enforceable in
accordance with all of their terms to the fullest extent permitted by law. If
any term thereof shall be invalid or unenforceable, the parties agree that such
term shall be stricken therefrom to
<PAGE>

the extent unenforceable, the same as if it never had been contained therein.
Such invalidity or unenforceability shall not extend to any other term thereof,
and the remaining terms thereof shall continue in effect to the fullest extent
permitted by law, the same as if such stricken term never had been contained
therein.

     13.  Construction.  This Second Amendment, the First Amendment, and the
          ------------
Original Lease shall each be construed according to the laws of the state in
which the Leased Premises are located.  Notwithstanding the drafting of the
Original Lease, the First Amendment, and this Second Amendment by Landlord,
neither this Second Amendment nor the First Amendment or the Original Lease
shall be construed against Landlord.  Except as otherwise provided therein, to
the extent that any provision thereof is subject to the consent or approval of
Landlord, such consent or approval may be withheld or conditioned in Landlord's
sole, absolute, and subjective discretion.

     14.  Entire Agreement. The Lease and the schedules and addenda attached to
          ----------------
the Original Lease, the First Amendment, and this Second Amendment set forth all
of the covenants, promises, agreements, representations, conditions, statements
and understandings between Landlord and Tenant concerning the Leased Premises,
the Building, and the Project, and there are no representations, either oral or
written between them other than those in the Lease. The Lease shall not be
amended or modified further except in writing signed by both parties.  Failure
to exercise any right under the Lease in one or more instances shall not be
construed as a waiver of the right to strict performance or as a further
amendment to the Lease.

     15.  Notices. Any notice or demand provided for or given pursuant to the
          -------
Lease shall be in writing and served on the parties at the addresses listed in
Paragraphs 2(k) and (l) hereof.  Any notice shall be either (i) personally
delivered to the addressee set forth above, in which case it shall be deemed

certified mail/return receipt requested, in which case it shall be deemed
delivered three (3) business days after being deposited in the U.S. Mail; (iii)
sent by a nationally recognized overnight courier, in which case it shall be

hours, in which case it shall be deemed delivered during the next normal
business hours), provided that an original is also sent by a nationally
recognized overnight courier and that such original is received within one (1)
business day thereafter.  The addresses and telecopier numbers listed in
Paragraphs 2(k) and (l) hereof may be changed by written notice to the other
party; provided, however, that no notice of a change of address or Fax number
shall be effective until the date of delivery of such notice. Copies of notices
are for informational purposes only and a failure to give or receive copies of
any notice shall not be deemed a failure to give notice.

     16.  Headings.  The headings contained in this Second Amendment are
          --------
included for convenience only and shall not be taken into consideration in any
construction or interpretation of this Second Amendment or any of its
provisions.

agreement therewith, and Tenant and Landlord each agrees to defend, indemnify
and hold harmless the other party against any loss, cost, expense or liability
for any compensation, commission, fee or charge, including reasonable attorney's
fees, resulting from any claim of any other broker, agent or finder claiming
under or through the indemnifying party in connection with the Expansion
Premises, this Second Amendment, or its negotiation.

     18.  Authority of Tenant.  If Tenant is a corporation, partnership, or
          -------------------

behalf of said corporation, partnership, or limited liability company represents

direction of Landlord.  Tenant shall cooperate with Landlord and its agents and
contractors to promote the efficient and expeditious completion of the

      ----------------------
Lease to the contrary and except as otherwise provided in the Amendment, no
delay in the Substantial Completion of the Additional Improvements within the

therefor, shall entitle Tenant to any abatement of Rent payable under the Lease
or any extension of the Lease Term beyond that set forth in the Lease.  In the
event that Tenant, prior to the Substantial Completion of the Additional
Improvements, does not, for any reason, comply with any requirement hereof or of
the Lease on or before the deadline established herein or in the Lease therefor,
the Expansion Date shall, without regard to the Substantial Completion of the
Additional Improvements or Tenant's occupancy of the Original Premises or the

with such requirement.

  6.  Access To Original Premises.  Tenant will use all reasonable and
      ---------------------------
diligent efforts to facilitate Landlord's installation of the Additional
Improvements within the Original Premises and the Expansion Premises and to not
interfere with Landlord and/or its agents and/or contractors in the performance
of such work within the Original Premises, the Expansion Premises, and/or the
Building.  Tenant will be responsible for any additional costs and expenses
incurred by Landlord as a result of Tenant's failure to facilitate such
installation or such interference, which additional costs and expenses shall be
payable by Tenant to Landlord upon demand therefor.  Tenant further agrees that,
to the extent permitted by law, Landlord and its principals shall not be liable
in any way for any injury or death to any person or persons, loss or damage to
any of the Additional Improvements or other installations made within the
Expansion Premises, or loss or damage to property placed therein or thereabout,
the same being Tenant's sole risk.  Nothing contained herein shall be deemed or
otherwise construed to obligate Landlord to install the Additional Improvements
within the Original Premises and/or the Expansion Premises at any time(s) other
than during normal business hours.

          ----------------------------------
forth with respect to the Additional Improvements, Landlord has no agreement
with Tenant and has no obligation to do any work with respect to the Leased
Premises.  Any other work in the Leased Premises which may be permitted by
Landlord pursuant to the terms and conditions of the Lease shall be done at
Tenant's sole cost and expense and in accordance with the terms and conditions
of the Lease.

     7.2  Limitation on Applicability.  This Schedule 3-B shall not be deemed
          ---------------------------
applicable to: (a) any space added to the Leased Premises at any time, whether

the Leased Premises (including any space added thereto) in the event of a
renewal or further extension of the Lease Term beyond that stated in the Lease,

Leased Premises which are not contemplated by this Schedule 3-B shall be
effected pursuant to a separate work letter agreement or other document in the
form then being used by Landlord, which agreement or other document shall
