                                      LOAN

     SECTION 2.1. TERMS.

          (a) The maximum aggregate principal amount of credit extended by
Lender to Borrower under this Agreement (the "Loan") that will be outstanding at
any time is Two Million and No/100 Dollars ($2,000,000.00) (the "Maximum Loan
Amount"). Notwithstanding anything in this Loan Agreement to the contrary, the
Maximum Loan Amount will be subject to the sublimit of $1,000,000 unless and
until Borrower requests an increase. If an Event of Default exists at the time
Borrower requests funding above such increase, such increase shall be subject to
approval of Lender's Credit Committee exercising its sole credit judgment.

          (b) The Loan shall be in the nature of a revolving line of credit, and
shall include sums advanced and other credit extended by Lender to or for the
benefit of Borrower from time to time under this Article II (each a "Revolving
Credit Loan") up to the Maximum Loan Amount depending upon the availability in
the Borrowing Base, the requests of Borrower pursuant to the terms and
conditions of Section 2.2, and on such other basis as Lender may reasonably
determine. The outstanding principal balance of the Loan may fluctuate from time
to time, to be reduced by repayments made by Borrower (which may be made without
penalty or

                                       6
<PAGE>   8

premium), and to be increased by future Revolving Credit Loans, advances and
other extensions of credit to or for the benefit of Borrower, and shall be due
and payable in full upon the expiration of the Term. For purposes of this
Agreement, any determination as to whether there is availability within the
Borrowing Base for advances or extensions of credit shall be made by Lender in
its sole and reasonable discretion and is final and binding upon Borrower absent
manifest error.

          (c) At Closing, Borrower shall execute and deliver to Lender a
promissory note evidencing Borrower's unconditional obligation to repay Lender
for Revolving Credit Loans, advances, and other extensions of credit made under
the Loan, in the form of Exhibit A to this Agreement (as amended, modified,
restated or replaced from time to time, the "Note"), dated the date of this
Agreement, payable to the order of Lender in accordance with the terms thereof.
The Note shall bear interest on the outstanding principal balance of the Note
from the date of the Note until repaid, with interest payable monthly in arrears
on the first Business Day of each month, at a rate per annum (on the basis of
the actual number of days elapsed over a year of 360 days) equal to the Base
Rate, provided that after the occurrence and during the continuance of an Event
of Default such rate shall be equal to the Default Rate. Upon Borrower's failure
to comply with the terms of this Agreement, Lender will be entitled, in addition
to exercising any other rights and remedies available to it, but in lieu of
charging the Default Rate, to assess a non-compliance fee which shall operate to
increase the Base Rate by two percent (2%) per annum during any period of
non-compliance. Lender shall be entitled to assess such fee whether or not an
Event of Default is declared or otherwise occurs. Each Revolving Credit Loan,
advance and other extension of credit shall be deemed evidenced by the Note,
which is deemed incorporated into and made a part of this Agreement by this
reference.

          (d) Subject to the terms and conditions of this Agreement, advances
under the Loan shall be made against a borrowing base equal to eighty percent
(80%) of Qualified Accounts (the "Borrowing Base"). Lender, in its sole credit
judgment may further adjust the Borrowing Base by applying percentages (known as
"liquidity factors") to Qualified Accounts based upon Borrower's actual recent
collection history in a manner consistent with Lender's underwriting practices
and procedures. Such liquidity factors may be adjusted by Lender throughout the
Term as warranted by Lender's underwriting practices and procedures in its sole
credit judgment.

     SECTION 2.2. LOAN ADMINISTRATION. Borrowings under the Loan shall be as
follows:

          (a) A request for a Revolving Credit Loan shall be made, or shall be
deemed to be made, in the following manner: (i) Borrower may give Lender notice
of its intention to borrow, in which notice Borrower shall specify the amount of
the proposed borrowing and the proposed borrowing date, not later than 2:00 p.m.
Eastern time two (2) Business Days before the proposed borrowing date; provided,
however, that no such request may be made at a time when there exists an Event
of Default; and (ii) the becoming due of any amount required to be paid under
this Agreement, whether as interest or for any other Obligation, shall be deemed
irrevocably to be a request for a Revolving Credit Loan on the day following the
due date in the

                                       7
<PAGE>   9

amount required to pay such interest or other Obligation if such was not paid by
Borrower on the due date.

          (b) Borrower hereby irrevocably authorizes Lender, and Lender agrees,
subject to the terms and conditions of this Agreement, to disburse the proceeds
of each Revolving Credit Loan requested, or deemed to be requested, as follows:
(i) the proceeds of each Revolving Credit Loan requested under subsection
2.2(a)(i) shall be disbursed by Lender by wire transfer to such bank account as
may be agreed upon by Borrower and Lender from time to time or elsewhere if
pursuant to written direction from Borrower; and (ii) the proceeds of each
Revolving Credit Loan deemed to be requested under subsection 2.2(a)(ii) shall
be disbursed by Lender by way of direct payment of the relevant interest or
other Obligation.

          (c) All Revolving Credit Loans, advances and other extensions of
credit to or for the benefit of Borrower shall constitute one general Obligation
of Borrower, and shall be secured by Lender's lien upon all of the Collateral.

          (d) Lender shall enter all Revolving Credit Loans as debits to a loan
account in the name of Borrower and shall also record in said loan account all
payments made by Borrower on any Obligations and all proceeds of Collateral
which are indefeasibly paid to Lender, and may record therein, in accordance
with customary accounting practice, other debits and credits, including interest
and all charges and expenses properly chargeable to Borrower. All collections
into the Concentration Account pursuant to Section 2.3 shall be applied first to
fees, costs and expenses due and owing under the Loan Documents, then to
interest due and owing under the Loan Documents, and then to principal
outstanding with respect to Revolving Credit Loans.

          (e) Lender will account to Borrower monthly with a statement of
Revolving Credit Loans, charges and payments made pursuant to this Agreement,
and such accounting rendered by Lender shall be deemed final, binding and
conclusive upon Borrower, absent manifest error, unless Lender is notified by
Borrower in writing to the contrary within thirty (30) days of the date each
accounting is mailed to Borrower. Such notice shall be deemed an objection to
those items specifically objected to in the notice.

     SECTION 2.3. COLLECTIONS, DISBURSEMENTS, BORROWING AVAILABILITY, AND
LOCKBOX ACCOUNT. (a) Lender shall establish and maintain a lockbox and a lockbox
account (the "Lockbox" and the "Lockbox Account", respectively) with BANK ONE,
N.A. (the "Lockbox Bank"), and Borrower shall execute with Lender and the
Lockbox Bank a Provider Account Agreement in substantially the form attached
hereto as Exhibit B (the "Lockbox Agreement"), together with any other
agreements or documents necessary to effectuate the intent of the parties as set
forth in this Section 2.3 or in the Lockbox Agreement as Lender may require.
Borrower shall ensure that all collections of Accounts are paid directly from
Account Debtors to the Lockbox. Borrower hereby irrevocably makes, constitutes
and appoints the Lockbox Bank (and all persons designated by the Lockbox Bank
for such purpose) as Borrower's true and lawful attorney and agent-in-fact to
endorse Borrower's name on all checks, items of payment or other

                                       8
<PAGE>   10

cash items that are acceptable for collection through the Federal Reserve System
(collectively, "Checks") payable to Rockwell Medical Technologies, Inc. and
Rockwell Transportation (or any reasonable variation of such names) with the
endorsement "CREDIT TO THE ACCOUNT OF HELLER HEALTHCARE FINANCE, INC.
XXXXXXXXXXXX"). Borrower agrees not to change the foregoing irrevocable
instructions to the Lockbox Bank prior to the termination of this Agreement
without the prior written consent of Lender. Notwithstanding anything in the
Lockbox Agreement to the contrary, Borrower agrees that it shall be liable for
any fees and charges in effect from time to time and charged by the Lockbox Bank
in connection with the Lockbox and the Lockbox Account, and that Lender shall
have no liability therefor. Borrower further acknowledges and agrees that, to
the extent such fees and charges are not paid by Borrower directly but are
satisfied using collections in the Lockbox Account, if applicable, such fees and
charges shall be deemed to be Revolving Credit Loans made by Lender hereunder
and, to the extent that the payment of such fees or charges by Borrower as
provided herein results in any overadvance under this Agreement, Borrower agrees
to immediately (upon notice) repay to Lender the amount of such overadvance. It
is understood that Lender's actions pursuant to this Section 2.3 are provided as
a convenience to Borrower and, in consideration thereof, Borrower agrees to
indemnify and hold Lender harmless from any and all liabilities, claims, losses
and demands whatsoever, including reasonable attorney's fees and expenses,
arising from or relating to Lender's or the Lockbox Bank's actions pursuant to
this Section 2.3.

          (b) Borrower agrees that all collections paid to the Lockbox and
deposited by Lender into the Lockbox Account under the Lockbox Agreement will be
immediately transferred by Lender into a depository account maintained by Lender
at Bank One, N.A., or such other financial institution as determined by Lender
in its sole discretion, by written notice to Borrowers and the Lockbox Bank (the
"Concentration Account"). Lender shall apply, on a daily basis, all funds
transferred into the Concentration Account pursuant to this Section 2.3 to
reduce the outstanding indebtedness under the Loan (in accordance with Section
2.2(d)), and all future Revolving Credit Loans, advances and other extensions of
credit to be made by Lender under the conditions set forth in this Article II.
To the extent that any collections of Accounts or proceeds of other Collateral
are not sent directly to the Lockbox but are received by Borrower, such
collections shall be held in trust for the benefit of Lender and immediately
remitted, in the form received, to the Lockbox Bank for transfer to the
Concentration Account immediately upon receipt by Borrower.

          (c) Borrower acknowledges and agrees that its compliance with the
terms of this Section 2.3 is essential, and that Lender will suffer immediate
and irreparable injury and have no adequate remedy at law, if Borrower, through
its acts or omissions, causes or permits Account Debtors to send payments other
than to the Lockbox, or if Borrower fails to immediately deposit collections of
Accounts or proceeds of other Collateral in the Lockbox Account as herein
required. Upon Borrower's failure to comply with the terms of this Section 2.3,
Lender will be entitled, in addition to exercising any other rights and remedies
available to it, to assess a non-compliance fee which shall operate to increase
the Base Rate by two percent (2%) per annum during any period of non-compliance.
Lender shall be entitled to assess such fee whether or not an Event of Default
is declared or otherwise occurs. All funds transferred from the

                                       9
<PAGE>   11

Concentration Account for application to Borrower's indebtedness to Lender shall
be applied to reduce the Loan balance, but for purposes of calculating interest
shall be subject to a seven Business Day clearance period. If as the result of
collections of Accounts pursuant to the terms and conditions of this Section 2.3
a credit balance exists with respect to the Concentration Account, such credit
balance shall not accrue interest in favor of Borrower, but shall be available
to Borrower at any time or times for so long as no Event of Default, and no
event or circumstance which, with notice or the passage of time (or both), would
constitute an Event of Default, exists.

     SECTION 2.4. FEES.

          (a) Upon execution of this Agreement, Borrower shall unconditionally
pay to Lender a commitment fee equal to one percent (1.0%) of the Maximum Loan
Amount (the "Commitment Fee"), payable in installments if and when aggregate
outstanding Revolving Credit Loans exceed the following thresholds:

$0 to $1,000,000                                              $10,000
$1,000,000 to $2,000,000                                      Additional $10,000
</TABLE>

By way of clarification, the maximum aggregate Commitment Fee due under this
Agreement is $20,000.

          (b) For so long as the Loan is available to Borrower, Borrower
unconditionally shall pay to Lender a monthly usage fee (the "Usage Fee") equal
to 0.0425% of the average amount by which the sublimit under the Maximum Loan
Amount exceeds the average amount of the outstanding principal balance of the
Revolving Credit Loans during the preceding month. The Usage Fee shall be
payable monthly in arrears on the first Business Day of each successive calendar
month.

          (c) For so long as the Loan is available to Borrower, Borrower
unconditionally shall pay to Lender a monthly loan management fee (the "Loan
Management Fee") equal to one-quarter of one percent (0.25%) of the average
amount of the outstanding principal balance of the Revolving Credit Loans during
the preceding month. The Loan Management Fee shall be payable monthly in arrears
on the first day of each successive calendar month.

          (d) Borrower shall pay to Lender all out-of-pocket audit and appraisal
fees in connection with audits and appraisals of Borrower's books and records
and such other matters as Lender shall deem reasonably appropriate, which shall
be due and payable on the first Business Day of the month following the date of
issuance by Lender of a request for payment thereof to Borrower, but not less
than ten (10) days after such request in the event that there is not

                                       10
<PAGE>   12

sufficient availability in the Borrowing Base to pay such fees as of such first
Business Day of the month. Absent the existence of an Event of Default, Borrower
shall not be required to pay to Lender the costs of more than four (4) audit or
appraisals per year.

          (e) Borrower shall pay to Lender, on demand, any and all reasonable
out-of pocket fees, costs or expenses which Lender or any participant pays to a
bank or other similar non-affiliated institution (including, without limitation,
any fees paid by Lender to any non-affiliated participant) arising out of or in
connection with (i) the forwarding to Borrower or any other Person on behalf of
Borrower, by Lender, of proceeds of Revolving Credit Loans made by Lender to
Borrower pursuant to this Agreement, and (ii) the depositing for collection, by
Lender or any participant, of any check or item of payment received or delivered
to Lender or any participant on account of Obligations up to a maximum of
$5,000.00 per year.

     SECTION 2.5. PAYMENTS. Principal payable on account of Revolving Credit
Loans shall be payable by Borrower to Lender immediately upon the earliest of
(i) the receipt by Borrower or Lender of any payments on or proceeds from any of
the Collateral, to the extent of such proceeds, (ii) the occurrence of an Event
of Default if the Loan and the maturity of the payment of the Obligations are
accelerated prior to cure of such Event of Default, or (iii) the termination of
this Agreement pursuant to Section 2.8 of this Agreement; provided, however,
that if any advance made by Lender in excess of the Borrowing Base shall exist
at any time, Borrower shall, immediately upon demand, repay such overadvance.
Interest accrued on the Revolving Credit Loans shall be due on the earliest of
(i) the first Business Day of each month (for the immediately preceding month),
computed on the last calendar day of the preceding month, (ii) the occurrence of
an Event of Default if the Loan and the maturity of the payment of the
Obligations are accelerated prior to cure of such Event of Default, or (iii) the
termination of this Agreement pursuant to Section 2.8. Except to the extent
otherwise set forth in this Agreement, all payments of principal and of interest
on the Loan, all other charges and any other obligations of Borrower under this
Agreement, shall be made to Lender to the Concentration Account, in immediately
available funds.

     SECTION 2.6. USE OF PROCEEDS. The proceeds of Lender's advances under the
Loan shall be used solely for working capital and for other costs of Borrower
arising in the ordinary course of Borrower's business.

     SECTION 2.7. INTEREST RATE LIMITATION. The parties intend to conform
strictly to the applicable usury laws in effect from time to time during the
term of the Loan. Accordingly, if any transaction contemplated by this Agreement
would be usurious under such laws, then notwithstanding any other provision of
this Agreement: (i) the aggregate of all interest that is contracted for,
charged, or received under this Agreement or under any other Loan Document shall
not exceed the maximum amount of interest allowed by applicable law (the
"Highest Lawful Rate"), and any excess shall be promptly credited to Borrower by
Lender (or, to the extent that such consideration shall have been paid, such
excess shall be promptly refunded to Borrower by Lender); (ii) neither Borrower
nor any other Person now or hereafter liable under this Agreement shall be
obligated to pay the amount of such interest to the extent that it is in

                                       11
<PAGE>   13

excess of the Highest Lawful Rate; and (iii) the effective rate of interest
shall be reduced to the Highest Lawful Rate. All sums paid, or agreed to be
paid, to Lender for the use, forbearance, and detention of the debt of Borrower
to Lender shall, to the extent permitted by applicable law, be allocated
throughout the full term of the Note until payment is made in full so that the
actual rate of interest does not exceed the Highest Lawful Rate in effect at any
particular time during the full term thereof. If at any time the rate of
interest under the Note exceeds the Highest Lawful Rate, the rate of interest to
accrue pursuant to this Agreement shall be limited, notwithstanding anything to
the contrary in this Agreement, to the Highest Lawful Rate, but any subsequent
reductions in the Base Rate shall not reduce the interest to accrue pursuant to
this Agreement below the Highest Lawful Rate until the total amount of interest
accrued equals the amount of interest that would have accrued if a varying rate
per annum equal to the interest rate under the Note had at all times been in
effect. If the total amount of interest paid or accrued pursuant to this
Agreement under the foregoing provisions is less than the total amount of
interest that would have accrued if a varying rate per annum equal to the
interest rate under the Note had been in effect, then Borrower agrees to pay to
Lender an amount equal to the difference between (x) the lesser of (A) the
amount of interest that would have accrued if the Highest Lawful Rate had at all
times been in effect, or (B) the amount of interest that would have accrued if a
varying rate per annum equal to the interest rate under the Note had at all
times been in effect, and (y) the amount of interest accrued in accordance with
the other provisions of this Agreement.

     SECTION 2.8. TERM.

          (a) Subject to Lender's right to cease making Revolving Credit Loans
to Borrower upon or during the continuance of any Event of Default, this
Agreement shall be in effect for a period of two (2) years from the Closing
Date, unless terminated as provided in this Section 2.8 (the "Term"), and this
Agreement shall be renewed for one-year periods thereafter upon the mutual
written agreement of the parties.

          (b) Notwithstanding anything in this Agreement to the contrary, Lender
may terminate this Agreement without notice upon and during the continuance of
an Event of Default.

          (c) Upon at least thirty (30) days prior written notice to Lender (the
"Termination Notice Period"), Borrower may terminate this Agreement at any time,
provided however, at the effective date of any termination prior to the end of
the Term, Borrower shall pay to Lender (in addition to the then outstanding
principal, accrued interest and other Obligations owing under the terms of this
Agreement and any other Loan Documents) as yield maintenance for the loss of
bargain and not as a penalty, the Termination Fee. Notwithstanding the
foregoing, the Termination Fee will be waived in the event that Borrower
terminates this Agreement following a 20% reduction in the Borrowing Base
resulting from Lender's unreasonable (i.e. lacking reasonable factual and
economic basis) disqualification of Accounts as Qualified Accounts pursuant to
the discretionary authority granted to Lender under Section 1.40(o) above. The
Termination Fee will not be waived in the event that the 20% Borrowing Base
reduction results from the occurrence of any of the events set forth in Sections
1.40(a)

                                       12
<PAGE>   14

through 1.40(n) or upon the Lender's reasonable disqualification of Accounts as
Qualified Accounts pursuant to Section 1.40(o) above.

          (d) All of the Obligations shall be immediately due and payable upon
the termination date stated in any notice of termination of this Agreement (the
"Termination Date"). All undertakings, agreements, covenants, warranties, and
representations of Borrower contained in the Loan Documents shall survive any
such termination until Borrower has paid the Obligations to Lender, in full, in
immediately available funds and Lender shall retain its liens in the Collateral
and all of its rights and remedies under the Loan Documents notwithstanding such
termination until Borrower has paid the Obligations to Lender, in full, in
immediately available funds.

          (e) Notwithstanding any provision of this Agreement which makes
reference to the continuance of an Event of Default, nothing in this Agreement
shall be construed to permit Borrower to cure an Event of Default following the
lapse of the applicable cure period, and Borrower shall have no such right in
any instance unless specifically granted in writing by Lender.

     SECTION 2.9. JOINT AND SEVERAL LIABILITY; BINDING OBLIGATIONS. Each entity
constituting Borrower shall be jointly and severally liable for all of the
obligations of Borrower under the Note and this Agreement. Each Borrower,
individually, expressly understands, agrees and acknowledges, that the loan
would not be made available on the terms herein in the absence of the collective
credit of all of the Borrowers, the joint and several liability of all
Borrowers, and the cross collateralization of the collateral of all Borrowers.
Accordingly, each Borrower, individually acknowledges that the benefit to each
of the participants in the facility as a whole constitutes reasonably equivalent
value, regardless of the amount of the loan actually borrowed by, advanced to,
or the amount of collateral provided by, any individual Borrower. In addition,
each entity comprising Borrower hereby acknowledges and agrees that all of the
representations, warranties, covenants, obligations, conditions, agreements and
other terms contained in this Agreement shall be applicable to and shall be
binding upon each entity comprising Borrower, and shall be binding upon all such
entities when taken together.

renewals thereof, (ii) the payment of all amounts advanced by Lender to
preserve, protect, defend, and enforce its rights under this Agreement and in

security and liens, in, to and in respect of the Accounts, including, without

          (b) All Borrower's money, securities and other property and the

Affiliate of Lender, whether for safekeeping, pledge, custody, transmission,
collection or otherwise, and all of Borrower's deposits (general or special),
balances, sums and credits, whether or not with Lender in each case, at any time
existing;

          (c) All of Borrower's right, title and interest in, to and in respect
of all goods relating to, or which by sale have resulted in, Accounts,
including, without limitation, all goods described in invoices or other
documents or instruments with respect to, or otherwise representing or

use, and vend goods utilizing any of the foregoing, and permits, licenses,
certifications, authorizations and approvals, and the rights of Borrower
thereunder, issued by any governmental, regulatory, or private authority,
agency, or entity whether now owned or hereafter acquired, together with all
cash and non-cash proceeds and products thereof; provided, however, that nothing
herein shall restrict Borrower's right to license its intangible assets to third
parties pursuant to arm's length licensing transactions;

          (g) All of Borrower's now owned or hereafter acquired inventory of
every description which is held by Borrower for sale or lease or is furnished by
Borrower under any contract of service or is held by Borrower as raw materials,
work in process or materials used or consumed in a business, wherever located,
and as the same may now and hereafter from time to time be constituted, together
with all cash and non-cash proceeds and products thereof;

          (h) All of Borrower's now owned or hereafter acquired machinery,
equipment, computer equipment, tools, tooling, furniture, fixtures, goods,

together with all additions, parts, fittings, accessories, special tools,

connection therewith, all replacements thereof and substitutions therefor, and
all cash and non-cash proceeds and products thereof; and

          (i) The proceeds (including, without limitation, insurance proceeds)
of all of the foregoing.

     Notwithstanding the foregoing, upon (a) Borrower's sale in the ordinary
course of business of any assets set forth in subsection 3.1(h) above, or (b)
Borrower's sale of furniture, fixtures and equipment from its facility located
in Wixom, Michigan, Lender agrees to release its lien on such assets subject to
sale by executing any documents necessary to formally effectuate such release.
Moreover, upon Borrower's achieving positive EBTDA (i.e. earnings before taxes,
depreciation and amortization, as determined in accordance with GAAP,
consistently applied) for two consecutive fiscal quarters as reported by
Borrower in its quarterly reporting to the

                                       15
<PAGE>   17

Securities and Exchange Commission (10 Qs), then Lender agrees to release its
lien on all assets set forth in subsections 3.1(f)(g) and (h) above.

     SECTION 3.2. LIEN DOCUMENTS. At Closing and thereafter as Lender deems
necessary in its sole discretion, Borrower shall execute and deliver to Lender,
or have executed and delivered (all in form and substance satisfactory to Lender
in its sole discretion):

          (a) UCC-1 Financing Statements pursuant to the Uniform Commercial Code
in effect in the jurisdiction(s) in which Borrower operates, which Lender may
file in any jurisdiction where any Collateral is or may be located and in any
other jurisdiction that Lender deems appropriate; provided that a carbon,
photographic, or other reproduction or other copy of this Agreement or of a
financing statement is sufficient as and may be filed in lieu of a financing
statement; and

          (b) Any other agreements, documents, instruments, and writings deemed
necessary by Lender or as Lender may otherwise request from time to time in its
sole and reasonable discretion to evidence, perfect, or protect Lender's lien
and security interest in the Collateral required under this Agreement.

     SECTION 3.3. COLLATERAL ADMINISTRATION.

          (a) All Collateral (except deposit accounts) will at all times be kept
by Borrower at its principal office(s) as set forth on Schedule 4.15 and shall
not be moved from such locations without the prior written consent of Lender,
which consent shall not be unreasonably withheld.

          (b) Borrower shall keep accurate and complete records of its Accounts
and all payments and collections thereon and shall submit to Lender on such
periodic basis as Lender shall request, but not more often than monthly, a sales
and collections report for the preceding period, in form satisfactory to Lender.
In addition, if Accounts in an aggregate face amount in excess of $50,000.00
become ineligible because they fall within one of the specified categories of
ineligibility set forth in the definition of Qualified Accounts or otherwise,
Borrower shall notify Lender of such occurrence on the first Business Day
following the date it became aware of such occurrence and the Borrowing Base
shall thereupon be adjusted to reflect such occurrence. If requested by Lender,
Borrower shall execute and deliver to Lender formal written assignments of all
of its Accounts monthly (or more frequently upon and during the continuance of
an Event of Default), which shall include all Accounts that have been created
since the date of the last assignment, together with copies of claims, invoices
or other information related thereto.

          (c) Whether or not an Event of Default has occurred, any of Lender's
officers, employees or agents shall have the right, at any time or times
hereafter, in the name of Lender or any designee of Lender or Borrower, to
verify the validity, amount or any other matter relating to any Accounts by
mail, telephone, telegraph or otherwise. Borrower shall cooperate fully with
Lender in an effort to facilitate and promptly conclude such verification
process.

                                       16
<PAGE>   18

          (d) To expedite collection, Borrower shall endeavor in the first
instance to make collection of its Accounts for Lender. Lender retains the right
at all times after the occurrence and during the continuance of an Event of
Default, to notify Account Debtors that Accounts have been assigned to Lender
and to collect Accounts directly in its own name and to charge reasonable
collection costs and expenses, including attorneys' fees, to Borrower.

     SECTION 3.4. OTHER ACTIONS. In addition to the foregoing, Borrower (i)
shall provide prompt written notice to each entity that is currently an Account
Debtor or who becomes an Account Debtor at any time following the date of this
Agreement that Lender has been granted a first priority lien and security
interest in, upon and to all Accounts applicable to such Account Debtor and
directs each Account Debtor to make payments into the Lockbox, and hereby
authorizes Lender, upon Borrower's failure to send such notices within fifteen
(15) days after the date of this Agreement (or fifteen (15) days after the
entity becomes an Account Debtor), to send any and all similar notices to such
Account Debtors, and (ii) shall do anything further that may be lawfully
required by Lender to secure Lender and effectuate the intentions and objects of
this Agreement, including but not limited to the execution and delivery of
lockbox agreements, continuation statements, amendments to financing statements,
and any other documents required under this Agreement. At Lender's request,
Borrower shall also immediately deliver to Lender all items for which Lender
must receive possession to obtain a perfected security interest. Borrower shall,
on Lender's demand, deliver to Lender all notes, certificates, and documents of
title, chattel paper, warehouse receipts, instruments, and any other similar
instruments constituting Collateral.

     SECTION 3.5. SEARCHES. Before Closing, and thereafter (as and when
determined by Lender in its sole discretion, but not more often than quarterly
absent the existence of an Event of Default or an event reasonably giving rise
to an Event of Default following the expiration of any applicable cure periods),
Lender will perform the searches described in clauses (a) and (b) below against
Borrower (the results of which are to be consistent with Borrower's
representations and warranties under this Agreement), all at Borrower's expense:

          (a) Uniform Commercial Code searches with the Secretary of State and
local filing offices of each jurisdiction where Borrower maintains its executive
offices, a place of business, or assets;

          (b) Judgment, federal tax lien and corporate and partnership tax lien
searches, in each jurisdiction searched under clause (a) above; and

     In addition, prior to Closing, at Borrower's expense, Borrower shall obtain
and deliver to Lender good standing certificates showing Borrower to be in good
standing in its state of formation and in each other state in which it is doing
and currently intends to do business for which qualification is required.

                                       17
<PAGE>   19

     SECTION 3.6. POWER OF ATTORNEY. Each of the officers of Lender is hereby
irrevocably made, constituted and appointed the true and lawful attorney for
Borrower (without requiring any of them to act as such) with full power of
substitution, during an Event of Default or following an event which, through
the passage of time, would become an Event of Default, to do the following: (i)
endorse the name of Borrower upon any and all checks, drafts, money orders, and
other instruments for the payment of money that are payable to Borrower and
constitute collections on Borrower's Accounts; (ii) execute in the name of
Borrower any financing statements, schedules, assignments, instruments,
documents, and statements that Borrower is obligated to give Lender under this
Agreement; and (iii) do such other and further acts and deeds in the name of
Borrower that Lender may deem necessary or desirable to enforce any Account or
other Collateral or perfect Lender's security interest or lien in any
Collateral. In addition, if Borrower breaches its obligation to direct payments
of the proceeds of the Collateral to the Lockbox Account, Lender, as the
irrevocably made, constituted and appointed true and lawful attorney for
Borrower pursuant to this paragraph, may, by the signature or other act of any
of Lender's officers (without requiring any of them to do so), direct any
federal, state or private payor or fiscal intermediary to pay proceeds of the
Collateral to Borrower by directing payment to the Lockbox Account.

                                   ARTICLE IV

                         REPRESENTATIONS AND WARRANTIES

     Except as specifically disclosed to Lender in writing to the contrary, each
entity comprising Borrower represents and warrants to Lender, and shall be
deemed to represent and warrant on each day on which any Obligations shall be
outstanding under this Agreement, that:

     SECTION 4.1. SUBSIDIARIES. Except as set forth in Schedule 4.1, Borrower
has no subsidiaries.

     SECTION 4.2. ORGANIZATION AND GOOD STANDING. Borrower is a corporation duly
organized, validly existing, and in good standing under the laws of its state of
formation, is in good standing as a foreign corporation in each jurisdiction in
which the character of the properties owned or leased by it therein or the
nature of its business makes such qualification necessary except where the
failure to be so qualified would not have a Material Adverse Effect, has the
corporate power and authority to own its assets and transact the business in
which it is engaged, and has obtained all material certificates, licenses and
qualifications required under all laws, regulations, ordinances, or orders of
public authorities necessary for the ownership and operation of all of its
properties and transaction of all of its business, except for certificates,
licenses and qualifications which the failure to obtain would not have a
Material Adverse Effect.

                                       18
<PAGE>   20

     SECTION 4.3. AUTHORITY. Borrower has full corporate power and authority to
enter into, execute, and deliver this Agreement and to perform its obligations
under this Agreement, to borrow the Loan, to execute and deliver the Note, and
to incur and perform the obligations provided for in the Loan Documents, all of
which have been duly authorized by all necessary corporate action. No consent or
approval of shareholders of, or lenders to, Borrower and no consent, approval,
filing or registration with any Governmental Authority is required as a
condition to the validity of the Loan Documents or the performance by Borrower
of its obligations under the Loan Documents.

     SECTION 4.4. BINDING AGREEMENT. This Agreement and all other Loan Documents
constitute, and the Note, when issued and delivered pursuant to this Agreement
for value received, will constitute, the valid and legally binding obligations
of Borrower, enforceable against Borrower in accordance with their respective
terms.

     SECTION 4.5. LITIGATION. Except as disclosed in Schedule 4.5, there are no
actions, suits, proceedings or investigations pending or threatened against
Borrower before any court or arbitrator or before or by any Governmental
Authority which, in any one case or in the aggregate, if determined adversely to
the interests of Borrower, could have a Material Adverse Effect. Borrower is not
in default with respect to any order of any court, arbitrator, or Governmental
Authority applicable to Borrower or its properties.

     SECTION 4.6. NO CONFLICTS. The execution and delivery by Borrower of this
Agreement and the other Loan Documents do not, and the performance of its
obligations under the Loan Documents will not, violate, conflict with,
constitute a material default under, or result in the creation of a lien or
encumbrance upon the property of Borrower (other than for the benefit of Lender)
under: (i) any provision of Borrower's articles of incorporation, (ii) any
provision of any law, rule, or regulation applicable to Borrower, or (iii) any
of the following: (A) any indenture or other agreement or instrument to which
Borrower is a party or by which Borrower or its property is bound; or (B) any
judgment, order or decree of any court, arbitration tribunal, or Governmental
Authority having jurisdiction over Borrower which is applicable to Borrower.

     SECTION 4.7. FINANCIAL CONDITION. The annual financial statements of
Borrower as of and for the period ending December 31, 2000 audited by Plante &
Moran and the unaudited financial statements of Borrower as of and for the
period ending February 28, 2001, certified by the chief financial officer of
Borrower on behalf of Borrower, which have been delivered to Lender, fairly
present the financial condition of Borrower and the results of its operations
and changes in financial condition as of the dates and for the periods referred
to, and have been prepared in accordance with GAAP. There are no material
unrealized or anticipated liabilities, direct or indirect, fixed or contingent,
of Borrower as of the dates of such financial statements which are not reflected
in such financial statements or in the notes to such financial statements. There
has been no material adverse change in the business, properties, or operations
of Borrower since December 31, 2000. Borrower's fiscal year ends on December 31.
The federal tax identification number of each entity comprising Borrower is as
described on Schedule 4.7.

                                       19
<PAGE>   21

     SECTION 4.8. NO DEFAULT. Except as set forth in Schedule 4.8, Borrower is
not in default under or with respect to any obligation in any respect which has
had a Material Adverse Effect, or which would reasonably be expected to
materially adversely affect the ability of Borrower to perform its obligations
under the Loan Documents. No Event of Default or event which, with the giving of
notice or lapse of time, or both, would become an Event of Default, has occurred
and is continuing.

     SECTION 4.9. TITLE TO PROPERTIES. Borrower has good and marketable title to
its properties and assets, including the Collateral and the properties and
assets reflected in the financial statements described in Section 4.7, subject
to no lien, mortgage, pledge, encumbrance or charge of any kind, other than

Agreement nor any other Loan Document nor any other agreement, document,
certificate, or statement furnished to Lender by or on behalf of Borrower in
connection with the transactions contemplated by this Agreement contains any

and is not contingent in any respect or for any reason;

          (e) To the best of Borrower's knowledge, there are no facts, events or
occurrences which in any way impair the validity or enforceability of any
Accounts or tend to reduce the amount payable thereunder from the face amount of
the claim or invoice and statements delivered to Lender with respect thereto;

          (a) Upon the occurrence of and during the continuance of an Event of
Default under this Agreement or the other Loan Documents, Lender, in addition to

or at law or in equity, may take any of the following steps (which list is given
by way of example and is not intended to be an exhaustive list of all such
rights and remedies):

               (i) Terminate the Loan, whereupon all outstanding Obligations
(including without limitation the Termination Fee) shall be immediately due and
payable;

               (ii) Exercise all other rights granted to it under this Agreement

now or hereafter in effect, including but not limited to:

                    (A) The right to take possession of, send notices regarding,
and collect directly the Collateral, with or without judicial process;

                    (B) The right to (by its own means or with judicial
assistance) enter any of Borrower's premises and take possession of the
Collateral or dispose of the Collateral on such premises in compliance with

other sums, and Borrower shall not resist or interfere with such action; and

                                       36
<PAGE>   38

          (b) Borrower agrees that a notice received by it at least fifteen (15)
days before the time of any intended public sale, or the time after which any
private sale or other disposition of the Collateral is to be made, shall be
deemed to be reasonable notice of such sale or other disposition. If permitted
by applicable law, any perishable Collateral which threatens to speedily decline
in value or which is sold on a recognized market may be sold immediately by
Lender without prior notice to Borrower. At any sale or disposition of
Collateral, Lender may (to the extent permitted by applicable law) purchase all
or any part of the Collateral, free from any right of redemption by Borrower,
which right is hereby waived and released. Borrower covenants and agrees not to
interfere with or impose any obstacle to Lender's exercise of its rights and
remedies with respect to the Collateral.

     SECTION 8.4. NATURE OF REMEDIES. Lender shall have the right to proceed
against all or any portion of the Collateral to satisfy the liabilities and
Obligations of Borrower to Lender in any order. All rights and remedies granted
Lender under this Agreement and under any agreement referred to in this
Agreement, or otherwise available at law or in equity, shall be deemed
concurrent and cumulative, and not alternative remedies, and Lender may proceed
with any number of remedies at the same time until the Loans, and all other
existing and future liabilities and obligations of Borrower to Lender, are
satisfied in full. The exercise of any one right or remedy shall not be deemed a
waiver or release of any other right or remedy, and Lender, upon the occurrence
of an Event of Default, may proceed against Borrower, and/or the Collateral, at
any time, under any agreement, with any available remedy and in any order.

                                   ARTICLE IX

                                  MISCELLANEOUS

     SECTION 9.1. EXPENSES AND TAXES.

          (a) Borrower agrees to pay, whether or not the Closing occurs, a
reasonable documentation preparation fee, together with actual audit and
appraisal fees and all other out-of-pocket charges and expenses incurred by
Lender in connection with the negotiation, preparation, legal review and
execution of each of the Loan Documents, including but not limited to UCC and
judgment lien searches and UCC filings and fees for post-Closing UCC and
judgment lien searches. In addition, Borrower shall pay all such fees associated
with any amendments to the Loan Documents following Closing.

          (b) Borrower also agrees to pay all reasonable out-of-pocket charges
and expenses incurred by Lender (including the fees and expenses of Lender's
counsel) in connection with the enforcement, protection or preservation of any
right or claim of Lender, the termination of this Agreement, the termination of
any liens of Lender on the Collateral, or the collection of any amounts due
under the Loan Documents. If Lender uses in-house counsel for any of these
purposes (i.e., for any task in connection with the enforcement, protection or
preservation of any

                                       37
<PAGE>   39

right or claim of Lender and the collection of any amounts due under its Loan
Documents), Borrower further agrees that its Obligations under the Loan
Documents include reasonable charges for such work commensurate with the fees
that would otherwise be charged by outside legal counsel selected by Lender for
the work performed.

          (c) Borrower shall pay all taxes (other than taxes based upon or
measured by Lender's income or revenues or any personal property tax), if any,
in connection with the issuance of the Note and the recording of the security
documents therefor. The obligations of Borrower under this clause (c) shall
survive the payment of Borrower's indebtedness under this Agreement and the
termination of this Agreement.

     SECTION 9.2. ENTIRE AGREEMENT; AMENDMENTS. This Agreement and the other
Loan Documents constitute the full and entire understanding and agreement among
the parties with regard to their subject matter and supersede all prior written
or oral agreements, understandings, representations and warranties made with
respect thereto. No amendment, supplement or modification of this Agreement nor
any waiver of any provision thereof shall be made except in writing executed by
the party against whom enforcement is sought.

     SECTION 9.3. NO WAIVER; CUMULATIVE RIGHTS. No waiver by any party to this
Agreement of any one or more defaults by the other party in the performance of
any of the provisions of this Agreement shall operate or be construed as a
waiver of any future default or defaults, whether of a like or different nature.
No failure or delay on the part of any party in exercising any right, power or
remedy under this Agreement shall operate as a waiver of such right, power or
remedy nor shall any single or partial exercise of any such right, power or
remedy preclude any other or further exercise of such right, power or remedy or
the exercise of any other right, power or remedy. The remedies provided for in
this Agreement are cumulative and are not exclusive of any remedies that may be
available to any party to this Agreement at law, in equity or otherwise.

any extent, invalid or unenforceable, the remainder of this Agreement and the
application of such term, covenant, or condition to parties or circumstances
other than those as to which it is held invalid or unenforceable, shall not be
affected thereby, and each term, covenant or condition shall be valid and
enforced to the fullest extent permitted by law. Upon determination that any
such term is invalid, illegal or unenforceable, Lender may, but is not obligated
to, advance funds to Borrower under this Agreement until the parties to this
Agreement amend this Agreement so as to effect the original intent of the
parties as closely as possible in a valid and enforceable manner.

     SECTION 9.6. SUCCESSORS AND ASSIGNS. This Agreement, the Note, and the

Agreement shall be deemed to include singular and plural and masculine, feminine

Parties (or any of them) have, whether now or in the future, (whether directly
or indirectly) against the Released Parties or any of them except those arising
out of gross negligence or willful misconduct. The Borrower acknowledges that
the foregoing release is a material inducement ot Lender's decision to extend to

perform any act on a Saturday, Sunday, or a legal holiday under the laws of the
State of Maryland (or other jurisdiction where Borrower is required to make the
payment or perform the act), the payment may be made or the act performed on the
next Business Day. Time is of the essence in Borrower's performance under this
Agreement and all other Loan Documents.

     SECTION 9.12. COMMISSIONS. The transaction contemplated by this Agreement
was brought about by Lender and Borrower acting as principals and without any
brokers, agents, or finders being the effective procuring cause. Borrower
represents that it has not committed Lender to the payment of any brokerage fee,
commission, or charge in connection with this

                                       40
<PAGE>   42

transaction. If any such claim is made on Lender by any broker, finder, or agent
or other person, Borrower will indemnify, defend, and hold Lender harmless from
and against the claim and will defend any action to recover on that claim, at
Borrower's cost and expense, including Lender's counsel fees. Borrower further
agrees that until any such claim or demand is adjudicated in Lender's favor, the
amount demanded will be deemed a liability of Borrower under this Agreement,
secured by the Collateral.

     SECTION 9.13. THIRD PARTIES. No rights are intended to be created under
this Agreement or under any other Loan Document for the benefit of any third
party donee, creditor, or incidental beneficiary of Borrower. Nothing contained
in this Agreement shall be construed as a delegation to Lender of Borrower's
duty of performance, including without limitation Borrower's duties under any
account or contract in which Lender has a security interest.

     SECTION 9.14. DISCHARGE OF BORROWER'S OBLIGATIONS. Lender, in its sole
discretion, shall have the right at any time, and from time to time, without
prior notice to Borrower if Borrower fails to do so, to: (i) obtain insurance
covering any of the Collateral as required under this Agreement; (ii) pay for
the performance of any of Borrower's obligations under this Agreement; (iii)
discharge taxes, liens, security interests, or other encumbrances at any time
levied or placed on any of the Collateral in violation of this Agreement unless
Borrower is in good faith with due diligence by appropriate proceedings
contesting those items; and (iv) pay for the maintenance and preservation of any
of the Collateral, provided Lender provides Borrower with written notice
promptly after doing so. Expenses and advances shall be added to the Loan, until
reimbursed to Lender and shall be secured by the Collateral. Any such payments
and advances by Lender shall not be construed as a waiver by Lender of an Event
of Default.

     SECTION 9.15. INFORMATION TO PARTICIPANTS. Lender may divulge to any
participant it may obtain in the Loan, or any portion of the Loan, all
information, and furnish to such participant copies of reports, financial
statements, certificates, and documents obtained under any provision of this
Agreement or any other Loan Document, provided such participant enters into an
agreement reasonably satisfactory to Borrower to keep such information
confidential.

     SECTION 9.16. INDEMNITY. Borrower hereby agrees to indemnify and hold
harmless Lender, its partners, officers, agents and employees (collectively,
"Indemnitee") from and against any liability, loss, cost, expense, claim,
damage, suit, action or proceeding ever suffered or incurred by Lender
(including reasonable attorneys' fees and expenses) arising from Borrower's
failure to observe, perform or discharge any of its covenants, obligations,
agreements or duties under this Agreement, or from the breach of any of the
representations or warranties contained in Article IV of this Agreement. In
addition, Borrower shall defend Indemnitee against and save it harmless from all
claims of any Person with respect to the Collateral. Notwithstanding any
contrary provision in this Agreement, the obligation of Borrower under this
Section 9.16 shall survive the payment in full of the Obligations and the
termination of this Agreement.

                                       41
<PAGE>   43

     SECTION 9.17. APPOINTMENT OF AGENT UNDER THIS AGREEMENT.

          (a) Each of the entities comprising Borrower hereby irrevocably
appoints and constitutes Thomas Klema as its agent to request and receive
Revolving Credit Loans (and to otherwise act on behalf of each such entity
pursuant to this Agreement and the other Loan Documents) from Lender in the name
or on behalf of each such entity. Lender may disburse the Revolving Credit Loans
to the bank account of any one or more of such entities without notice to any of
the other entities comprising Borrower or any other Person at any time obligated
on or in respect of the Obligations.

          (b) Each of the entities comprising Borrower hereby irrevocably
appoints and constitutes Thomas Klema as its agent to receive statements of
account and all other notices from Lender with respect to the Obligations or
otherwise under or in connection with this Agreement and the other Loan
Documents.

          (c) No purported termination of the appointment of Thomas Klema as
agent shall be effective without the prior written consent of Lender.

     SECTION 9.18. LENDER APPROVALS. Unless expressly provided herein to the
contrary, any approval, consent, waiver or satisfaction of Lender with respect
to any matter that is the subject of this Agreement, the other Loan Documents
may be granted or withheld by Lender in its sole and absolute discretion.

     SECTION 9.19. CHOICE OF LAW; CONSENT TO JURISDICTION. THIS AGREEMENT AND
THE NOTE SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE
STATE OF MARYLAND, WITHOUT REGARD TO ANY OTHERWISE APPLICABLE PRINCIPLES OF
CONFLICTS OF LAWS. IF ANY ACTION ARISING OUT OF THIS AGREEMENT OR THE NOTE IS
COMMENCED BY LENDER IN THE STATE COURTS OF THE STATE OF MARYLAND OR IN THE U.S.
DISTRICT COURT FOR THE DISTRICT OF MARYLAND, BORROWER HEREBY CONSENTS TO THE
JURISDICTION OF ANY SUCH COURT IN ANY SUCH ACTION AND TO THE LAYING OF VENUE IN
THE STATE OF MARYLAND. ANY PROCESS IN ANY SUCH ACTION SHALL BE DULY SERVED IF
MAILED BY REGISTERED MAIL, POSTAGE PREPAID, TO BORROWER AT ITS ADDRESS DESCRIBED
IN SECTION 9.4. OR IF SERVED BY ANY OTHER MEANS PERMITTED BY APPLICABLE LAW.

     SECTION 9.20. INTENTIONALLY DELETED

     SECTION 9.21. WAIVER OF TRIAL BY JURY. BORROWER HEREBY (A) COVENANTS AND
AGREES NOT TO ELECT A TRIAL BY JURY OF ANY ISSUE TRIABLE OF RIGHT BY A JURY, AND
(B) WAIVES ANY RIGHT TO TRIAL BY JURY FULLY TO THE EXTENT THAT ANY SUCH RIGHT
SHALL NOW OR HEREAFTER EXIST. THIS WAIVER OF RIGHT TO TRIAL BY JURY IS
SEPARATELY GIVEN,

                                       42
<PAGE>   44

KNOWINGLY AND VOLUNTARILY, BY BORROWER, AND THIS WAIVER IS INTENDED TO ENCOMPASS
INDIVIDUALLY EACH INSTANCE AND EACH ISSUE AS TO WHICH THE RIGHT TO A JURY TRIAL
WOULD OTHERWISE ACCRUE. LENDER IS HEREBY AUTHORIZED AND REQUESTED TO SUBMIT THIS
AGREEMENT TO ANY COURT HAVING JURISDICTION OVER THE SUBJECT MATTER AND THE
PARTIES TO THIS AGREEMENT, SO AS TO SERVE AS CONCLUSIVE EVIDENCE OF BORROWER'S
WAIVER OF THE RIGHT TO JURY TRIAL. FURTHER, BORROWER HEREBY CERTIFIES THAT NO
REPRESENTATIVE OR AGENT OF LENDER (INCLUDING LENDER'S COUNSEL) HAS REPRESENTED,
EXPRESSLY OR OTHERWISE, TO BORROWER THAT LENDER WILL NOT SEEK TO ENFORCE THIS
WAIVER OF RIGHT TO JURY TRIAL PROVISION.

     SECTION 9.22. CONFESSION OF JUDGMENT. UPON THE OCCURRENCE AND DURING THE
CONTINUANCE OF AN EVENT OF DEFAULT, BORROWER AUTHORIZES ANY ATTORNEY ADMITTED TO
PRACTICE BEFORE ANY COURT OF RECORD IN THE UNITED STATES OR THE CLERK OF SUCH
COURT TO APPEAR ON BEHALF OF BORROWER IN ANY COURT IN ONE OR MORE PROCEEDINGS,
OR BEFORE ANY CLERK THEREOF OF PROTHONOTARY OR OTHER COURT OFFICIAL, AND TO
CONFESS JUDGMENT AGAINST BORROWER IN FAVOR OF LENDER IN THE FULL AMOUNT DUE ON
THIS AGREEMENT (INCLUDING PRINCIPAL, ACCRUED INTEREST AND ANY AND ALL CHARGES,
FEES AND COSTS) PLUS REASONABLE ATTORNEYS' FEES NOT TO EXCEED FIFTEEN PERCENT
(15%) OF THE AMOUNT DUE, PLUS COURT COSTS, ALL WITHOUT PRIOR NOTICE OR
OPPORTUNITY OF BORROWER FOR PRIOR HEARING. BORROWER AGREES AND CONSENTS THAT
VENUE AND JURISDICTION SHALL BE PROPER IN THE CIRCUIT COURT OF ANY COUNTY OF THE
STATE OF MARYLAND OR OF BALTIMORE CITY, MARYLAND, OR IN THE UNITED STATES
DISTRICT COURT FOR THE DISTRICT OF MARYLAND. BORROWER WAIVES THE BENEFIT OF ANY
AND EVERY STATUTE, ORDINANCE, OR RULE OF COURT WHICH MAY BE LAWFULLY WAIVED
CONFERRING UPON BORROWER ANY RIGHT OR PRIVILEGE OF EXEMPTION, HOMESTEAD RIGHTS,
STAY OF EXECUTION, OR SUPPLEMENTARY PROCEEDINGS, OR OTHER RELIEF FROM THE
ENFORCEMENT OR IMMEDIATE ENFORCEMENT OF A JUDGMENT OR RELATED PROCEEDINGS ON A
JUDGMENT. THE AUTHORITY AND POWER TO APPEAR FOR AND ENTER JUDGMENT AGAINST
BORROWER SHALL NOT BE EXHAUSTED BY ONE OR MORE EXERCISES THEREOF, OR BY ANY
IMPERFECT EXERCISE THEREOF, AND SHALL NOT BE EXTINGUISHED BY ANY JUDGMENT
ENTERED PURSUANT THERETO; SUCH AUTHORITY AND POWER MAY BE EXERCISED ON ONE OR
MORE OCCASIONS FROM TIME TO TIME, IN THE SAME OR DIFFERENT JURISDICTIONS, AS
OFTEN AS LENDER SHALL DEEM NECESSARY, CONVENIENT, OR PROPER.

                                       43

     SECTION 9.23. CONFIDENTIALITY. Lender agrees to keep all information
provided to it by Borrower strictly confidential and not to disclose any of such
information to any third party, except as provided by Section 9.15.

     SECTION 9.24. TERMINATION. Promptly following the Termination of the Loan
and the payment by Borrower of all Obligations, Lender will terminate all Liens
and take such other actions as reasonably requested by Borrower to reflect the
termination of this Agreement and the Loans.

Third Amendment to Lease

      This THIRD AMENDMENT TO LEASE
(“Amendment”) effective this 20th
day of December, 2000, by and between ESPERION THERAPEUTICS, INC., (“Lessee”), and STATE-94 LIMITED PARTNERSHIP,
(“Lessor”), serves to amend the Lease for the premises known as 695 KMS Place, Ann Arbor, Michigan, hereof for the
purpose of renewing and extending said Lease.

WITNESSETH

      WHEREAS, Lessor and Lessee entered into that certain lease dated November 30, 1998 (as amended, the
“Lease”) for premises consisting of approximately 12,400 square feet in the building described hereinabove.
Lessor and Lessee entered into a First Amendment to Lease dated 12/28/98 to address construction reimbursements.
Lessor and Lessee entered into a Second Amendment to the Lease dated April 6, 2000 increasing Lessee’s total area
to approximately 18,813 square feet.

NOW, THEREFORE, Lessor and Lessee, in consideration of the mutual covenants herein contained, and for other good
and valuable consideration, do hereby agree that the Lease is amended as follows:

	•	 	Lessor and Lessee agree that the correct square footage of the demised premises is 20,118 square feet
and the Lease is hereby amended to reflect the correct square footage. Lessee shall not be liable for any
additional rent due to the increase in square footage prior to 1/1/01.

	•	 	Increased Real Property Taxes and Operating Expenses and Utilities. For the period commencing January
1, 2001 and ending on the Lease termination date, Lessee shall pay its pro-rata share of taxes, utilities
and operating expenses in accordance with the Lease. Said share shall be 15.93% of the total.

	•	 	Lessor and Lessee mutually agree to extend Lessee’s lease term for three years, through and including
December 31, 2003. Lessee has no rights of first refusal on any space in the building. Lessee shall be
granted one three- (3) year option to renew as detailed in this Amendment.

Tenant Improvement Allowances: Lessor shall provide Lessee with a Tenant Improvement allowance of $25,000

	 	 	to be
utilized by Lessee to make renovations and improvements to the leased  premises, including without
limitation, to the heating and cooling system of the premises. Upon receipt of invoices and, if
reasonably required by Lessor, fully executed lien waivers in an amount up to the $25,000.00 allowance,
Lessee may deduct $25,000 from the rent due for the following month (but no sooner than March, 2001.)
	 
	 	 	Furthermore, promptly upon delivery of additional paid receipts and, if reasonably required by Lessor,
fully executed lien waivers of up to $75,000 in the aggregate, Lessor shall pay to Lessee that amount
(to a maximum of $75,000.00 in total) for additional improvements to the leased premises. However,
Lessee shall repay said $75,000 allowance as additional rent amortized over thirty-six (36) months plus
interest at nine and one-half (9.5) percent per annum.
	 
	 	 	Lessee may make renovations to the leased premises with contractors selected by Lessee, but all such
contractors shall be reasonably acceptable to Lessor. Lessor shall provide its

	 	 	consent or denial with
reasons therefor within five (5) business days of Lessee’s request for consent. Lessee hereby agrees to
indemnify, defend and hold Lessor harmless from any and all claims whatsoever in nature, including
construction liens, to the extent resulting from renovations made by Lessee. Lessee shall not make any
improvements to the demised premises without the prior written consent of the Lessor. Such consent will
be delivered within five (5) business days and shall not be unreasonably withheld.
	 
	 	 	Section 2001 is hereby amended as follows: Lessee shall insure all improvements Lessee makes.

Rent: Effective January 1, 2001, and subject to the credits and allowances set forth above, Lessee shall pay
to

	 	 	Lessor base monthly rent and the amortized improvement allowance for the premises in the sum of One
million fifty-one thousand two and 00/100 ($1,051,002.00) Dollars in monthly installments on the first
day of each month as follows:

	 	•		For the period January 1, 2001 through December 31, 2001 installments of Twenty-eight thousand
three hundred fifty-six and 25/100 ($28,356.25) Dollars;

	 	•	 	For the period of January 1, 2002 through December 31, 2002 installments of Twenty-nine
thousand one hundred ninety-four and 50/100 ($29,194.50) Dollars;

	 	•	 	For the period of January 1, 2003 through December 31, 2003 installments of Thirty thousand
thirty-two and 75/100 ($30,032.75) Dollars.

All rent shall be paid in accordance with Paragraph 402 of the Lease.

Option: Section 3401 of the Lease shall be changed to read as follows:

	 	 	Lessee will have the option to extend and renew the Term of this Lease for one (1) additional term of
three (3) years (which shall be referred to as a “Renewal Term”). The Renewal Term will commence January
1, 2004. Rent during the Renewal Term shall be made in monthly installments as follows:

	 		 •	For the period January 1, 2004 through December 31, 2004 installments of $30,428.48;

	 		 •	For the period January 1, 2005 through December 31, 2005 installments of $31,949.90;

	 		 •	For the period January 1, 2006 through December 31, 2006 installments of $33,547.39.

	 	 	Otherwise, the Lease shall continue on the same terms and conditions, except that there will be no
further options to renew the Term after the Renewal Term. The renewal option shall be exercisable by
written notice to Lessor not later than nine (9) months before the expiration of the current Term,
provided Lessee is not in default under any of the terms or conditions of this Lease at the date Lessee
gives notice of renewal or at any time thereafter to and including the first day of the Renewal Term.
Failure to timely exercise Lessee’s option to renew, in writing, shall forfeit Lessee’s rights under
this Section. Lessee expressly waives any oral right to renew or any claim for renewal based upon oral
promises of Lessor or its agents.

Assignment: Section 1501 of the Lease shall be amended to read as follows:

	 	 	Lessee shall submit to Lessor, with any request for Lessor’s consent to any proposed assignment, written
evidence of the business experience and financial condition of the proposed assignee, and a description
of the business proposed to be conducted in the Premises by the assignee. Lessor will have the right to
disapprove of any proposed

	 	 	assignment for any lawful reason Lessor determines in good faith, which may
include (without limitation) the business experience and/or financial condition of the proposed
assignee, and/or the nature of the business to be conducted in the Premises. Upon approval of proposed
assignee, Lessee shall be responsible for all reasonable attorneys’ fees incurred by Lessor to draft or
review any documents necessary to transfer all legal and financial responsibility to the assignee.

Except as expressly modified herein, all terms, conditions and provisions of the Lease are hereby ratified and
affirmed and remain in full force and effect.

Submission of this Amendment by LESSOR is not an offer to enter into this Amendment but rather is a solicitation
for such an offer by LESSEE. LESSOR shall not be bound by this Amendment until LESSOR has executed and delivered
the same to LESSEE.

IN WITNESS WHEREOF, the parties hereto have executed this Amendment as of the day and year first above written.
