                                 LOAN AGREEMENT

         This Loan Agreement (the "Agreement") is entered into as of June 21,
2001, by and among BANK OF AMERICA, N.A., a national banking association
("Bank"), CHATTEM, INC., a Tennessee corporation ("Chattem"), and SIGNAL

                               W I T N E S S E T H
                               -------------------

         WHEREAS, Borrowers have requested that Bank make revolving credit loans
to Borrowers in an aggregate amount from time to time outstanding not to exceed
$10,000,000; and

         WHEREAS, Bank, in reliance upon the representations and inducements of
Borrowers, has agreed to make such loans upon the terms and conditions
hereinafter set forth;

         WHEREAS, this Agreement constitutes a replacement of those certain
Credit Agreements dated as of March 24, 1998, as amended, by and among Chattem,
Signal, NationsBank of Tennessee, N.A., as Agent, and the other lenders party
thereto, including any related notes, guarantees, collateral documents,
instruments, and agreements executed in connection therewith;

         NOW, THEREFORE, for good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the parties agree as follows:

         1.       DEFINITIONS.  The following terms shall have the meaning set
forth with respect thereto:

plus 2.5%.

                  (b) "ADJUSTED LIBOR FLOATING RATE":  means the LIBOR Floating
Rate plus 2.5%.

                  (c) "BASE RATE": means, for any day, the rate per annum

equal to the greater of (a) the Federal Funds Rate in effect on such day plus

the Bank shall have determined (which determination shall be conclusive absent
manifest error) that it is unable after due inquiry to ascertain the Federal
Funds Rate for any reason, including the inability or failure of the Bank to
obtain sufficient quotations in accordance with the terms hereof, the Base Rate
shall be determined without regard to clause (a) of the first sentence of this
definition until the circumstances giving rise to such inability no longer
exist. Any change in the Base Rate due to a change in the Prime Rate or the
Federal Funds Rate shall be effective on the effective date of such change in
the Prime Rate or the Federal Funds Rate, respectively.

                  (d) "BASE RATE LOAN":  means any Revolving Credit Loan bearing
interest at a rate determined by reference to the Base Rate.

                                      ---------------------------------

(or against any other category of liabilities that includes deposits by
reference to which the interest rate of Eurodollar Loans is determined), whether

on and as of the effective date of any change in the Eurodollar Reserve
Percentage.

                  (l) "ERISA": means the Employee Retirement Income Security Act
of 1976, as amended, and any successor statute thereto, as interpreted by the

successor sections.

falls in the next succeeding calendar month, then on the next preceding Business
Day), (b) no Interest Period shall extend beyond April 1, 2002, and (c) where an
Interest Period begins on a day for which there is no numerically corresponding

of credit to any debtor. If Bank of America, N.A. ceases to publish a Prime

         2.       LOANS.

                  (a) REVOLVING CREDIT LOANS.

                           (i) Subject to the terms and conditions hereof, the
Bank agrees to make revolving credit loans ("Revolving Credit Loans") to
Borrowers from time to time during the Commitment Period in an aggregate
principal amount at any one time outstanding not to exceed the Maximum Credit
Amount. Notwithstanding anything to the contrary contained in this Agreement, if
the aggregate principal amount of the Revolving Credit Loans at any time
outstanding exceeds the Maximum Credit Amount, the Borrowers shall immediately
pay to the Bank such amounts necessary to reduce the then outstanding principal
amount of the Revolving Credit Loans to an amount not exceeding such Maximum
Credit Amount. The Revolving Credit Loans made by the Bank shall be evidenced by
a Promissory Note dated the date of this Agreement (that Promissory Note
together with all renewals, extensions, amendments, replacements or
rearrangements thereof being collectively referred to herein as the "Note(s)").
Borrowers may borrow, repay, and re-borrow amounts under the Revolving Credit
Loans subject to the terms and limitations contained in this Agreement and the
other Loan Documents.

                           (ii) By no later than 11:00 A.M. (A) one (1) Business
Day prior to the requested borrowing of Revolving Credit Loans that will be Base
Rate Loans or LIBOR Floating Rate Loans or (B) three (3) Business Days prior to
the date of the requested borrowing of Revolving Credit Loans that will be
Eurodollar Loans, the Borrowers (or either of them) shall submit a written
Notice of Borrowing in form acceptable to Bank (or telephone notice promptly
confirmed in writing) to the Bank setting forth (a) the amount requested and the
date requested, (b) whether such Revolving Credit Loan shall accrue interest at
the Base Rate, the Adjusted

                                        5
<PAGE>

LIBOR Floating Rate, or the Adjusted Eurodollar Rate, and (c) with respect to
Revolving Credit Loans that will be Eurodollar Loans, the Interest Period
applicable thereto. Upon compliance with the terms and conditions hereof, Bank
shall make the amount of the requested Revolving Credit Loans available to the
Borrowers by crediting the Operating Account (or in such other manner as
requested by Borrowers and acceptable to Bank in its sole discretion). The
failure of Bank to require any written request for an advance of Revolving
Credit Loans or to follow any other procedures set forth in this Agreement shall
not in any way affect the treatment of any advance into the Operating Account as
an advance of Revolving Credit Loans under this Agreement.

                           (iii) Bank shall maintain on its books an account
(the "Credit Account") which shall be debited for all Revolving Credit Loans and
other amounts chargeable to Borrowers with respect thereto (including interest
accruing thereon) and credited for all payments received on the Revolving Credit
Loans. Each month the Bank shall render to Borrowers a written statement of the
Credit Account which shall be deemed correct and accepted by and binding upon
the Borrowers unless the Bank receives a written statement of the Borrowers'
specific exceptions thereto within thirty (30) days from the date of mailing of
the written statement to Borrowers. The statements of the Credit Account and
books of account of the Bank shall constitute prima facie evidence of the
balance in the Credit Account.

                           (iv) The agreement of the Bank to make any Revolving
Credit Loans is subject to the satisfaction of the following conditions
precedent:

                           (1)      REPRESENTATIONS AND WARRANTIES. Each of the
                                    representations and warranties made by the
                                    Borrowers in or pursuant to any Loan
                                    Document shall be true and correct in all
                                    material respects on and as of such date as
                                    if made on and as of such date, and by this
                                    subsection, the Borrowers represent and
                                    warrant that on the date of each advance of
                                    the Revolving Credit Loans, unless such
                                    representation or warranty refers to another
                                    date, such representations and warranties
                                    shall be true and correct in all material
                                    respects;

                           (2)      NO DEFAULT. No Event of Default shall have
                                    occurred or shall occur after giving effect
                                    to the Revolving Credit Loans requested to
                                    be made on such date, and no other event
                                    shall have occurred which with notice or
                                    lapse of time may constitute an Event of
                                    Default;

                           (3)      ADDITIONAL DOCUMENTS.  The Bank shall have
                                    received such additional documents,
                                    instruments, legal opinions or items of
                                    information reasonably requested by it; and

                           (4)      ADDITIONAL MATTERS. All company and other
                                    proceedings, and all documents, instruments
                                    and other legal matters in connection with
                                    the transactions contemplated by this
                                    Agreement shall be reasonably satisfactory
                                    in form and substance to the Bank.

                                        6
<PAGE>

                           (v) Upon at least three (3) Business Days' notice to
Bank, the Borrowers shall have the right to permanently terminate or reduce the
aggregate unused amount of the Revolving Credit Loans (in other words, reduce
the Maximum Credit Amount) at any time or from time to time; provided that (A)
each partial reduction shall be in an aggregate amount at least equal to
$500,000 and in integral multiples of $100,000 above such amount and (B) no
reduction shall be made which would reduce the Maximum Credit Amount to an
amount less than the aggregate amount of then outstanding Revolving Credit
Loans. Any reduction in (or termination of) the Revolving Credit Loans
(including any reduction in the Maximum Credit Amount) shall be permanent and
may not be reinstated.

                           (vi) Borrowers shall have the option, on any Business
Day, to continue in existence Eurodollar Loans for a subsequent Interest Period,
to convert Base Rate Loans and LIBOR Floating Rate Loans into Eurodollar Loans
or to convert Eurodollar Loans into Base Rate Loans or LIBOR Floating Rate
Loans, or to convert Base Rate Loans to LIBOR Floating Rate Loans or LIBOR
Floating Rate Loans to Base Rate Loans provided, however, that (a) each such
continuation or conversion must be requested by Borrowers (or either of them)
pursuant to a written notice of continuation/conversion in form acceptable to
Bank, (b) Eurodollar Loans may only be continued or converted into Base Rate
Loans or LIBOR Floating Rate Loans on the last day of the Interest Period
applicable thereto, (c) Eurodollar Loans may not be continued nor may Base Rate
Loans or LIBOR Floating Rate Loans be converted into Eurodollar Loans during the
existence and continuation of an Event of Default under this Agreement, and (d)
any request to extend a Eurodollar Loan that fails to comply with the terms
hereof or any failure to request an extension of a Eurodollar Loan at the end of
an Interest Period shall constitute a request for conversion to a Base Rate Loan
on the last day of the applicable Interest Period. Each continuation or
conversion must be requested by Borrowers no later than 11:00 A.M. (a) one (1)
Business Day prior to the date of the requested conversion of a Eurodollar Loan
to a Base Rate Loan or LIBOR Floating Rate Loan, a Base Rate Loan to a LIBOR
Floating Rate Loan, or a LIBOR Floating Rate Loan to a Base Rate Loan or (b)
three Business Days prior to the date for a requested extension of a Eurodollar
Loan or conversion of a Base Rate Loan or LIBOR Floating Rate Loan to a
Eurodollar Loan, in each case pursuant to a written notice of continuation/
conversion submitted to Bank which shall set forth (i) whether the Borrowers
wish to continue or convert such Revolving Credit Loans and (ii) if the request
is to continue a Eurodollar Loan or convert a Base Rate Loan or LIBOR Floating
Rate Loan to a Eurodollar Loan, the Interest Period applicable thereto. If for
any reason whatsoever there is any outstanding Revolving Credit Loan with
respect to which an applicable request is not in place designating an interest
rate option available under this Agreement, then that Revolving Credit Loan
shall be deemed for all purposes of this Agreement and the other Loan Documents
to be a Base Rate Loan until an appropriate designation is effective. Bank may
record the date and the amount of each payment or prepayment of principal on a
Revolving Credit Loan, each continuation thereof, each conversion of all or a
portion thereof to another applicable interest rate, and in the case of
Eurodollar Loans the length of the Interest Period with respect thereto, on its
books and records and such recordation shall constitute prima facie evidence of
the accuracy of the information so recorded in the absence of manifest error.

                           (vii) Each request for a borrowing, conversion or
continuation shall be subject to the requirements that (a) each Eurodollar Loan
shall be in a minimum amount of $1,000,000 and in $250,000 increments in excess
thereof, (b) each Base Rate Loan or LIBOR Floating Rate Loan shall be in a
minimum amount of the lesser of $500,000 (and $100,000 increments above that) or
the remaining amount available under the Revolving Credit Loans, and (c) no more
than three (3) Eurodollar Loans shall, in the aggregate, be outstanding
hereunder at any one time unless consented to by Bank in writing.

                  (b) INTEREST RATES AND PAYMENT TERMS.

                           (i) All Base Rate Loans shall accrue interest at the
Base Rate, all Eurodollar Loans shall accrue interest at the Adjusted Eurodollar
Rate, and all LIBOR Floating Rate Loans shall accrue interest at the Adjusted
LIBOR Floating Rate. Upon the occurrence of any Event of Default hereunder, the
principal of, and to the extent permitted by law, interest on the Revolving
Credit Loans and any other amounts owing hereunder, under any of the Notes, or
under any other Loan Document shall bear interest, payable on demand, at a per
annum rate equal to the then applicable interest rate plus 2%. In addition to
the foregoing remedies, to the extent permitted by applicable law, Borrowers
shall pay on demand to Bank a delinquency charge in the amount of five percent
(5%) of any payment not received within five days of the date due to defray
costs incidental to collecting such late payment (such late payment charges
payable notwithstanding any applicable cure period).

                           (ii) Interest on Revolving Credit Loans shall be due
and payable in arrears on each Interest Payment Date. If an Interest Payment
Date falls on a date which is not a Business Day, such Interest Payment Date
shall be deemed to be the next succeeding Business Day (subject to accrual of
interest for the period of extension), except in the case of Eurodollar Loans
where the next succeeding Business Day falls in the next succeeding calendar
month, then on the next preceding Business Day. All outstanding principal,
interest and other amounts owing under this Agreement, the Notes or any other
Loan Document, if not sooner due and payable in accordance with the terms hereof
or thereof, shall be due and payable in full on April 1, 2002.

                           (iii) All payments of principal, interest, and other
amounts owing under this Agreement, the Notes and the other Loan Documents must
be received not later than 2:00 P.M. on the date when due, at Bank's offices at
633 Chestnut Street, Chattanooga, Tennessee. Payments received after such time
shall be deemed to have been received on the next Business Day.

                           (iv) Borrowers shall have the right to prepay
Revolving Credit Loans in whole or in part from time to time without premium or
penalty; provided, however, that (i) Eurodollar Loans may only be prepaid at the
end of the applicable Interest Period on at least three (3) Business Days' prior
written notice to Bank (provided that Borrowers may prepay at any other time so
long as Borrowers pay to Bank all breakage and redeployment costs incurred in
connection with those prepayments); (ii) Base Rate Loans and LIBOR Floating Rate
Loans may only be prepaid after written notice to Bank not later than 11:00 A.M.
on the Business Day of the applicable prepayment; and (iii) each such partial
prepayment shall be in a minimum principal amount of $500,000 and in increments
of $100,000 in excess thereof.

                  (c) FEES. In consideration of the commitment to make Revolving
Credit Loans, Borrowers agree to pay Bank a fee equal to one-quarter of one
percent (0.25%) per annum on the Unused Commitment (the "Commitment Fees"). The
accrued Commitment Fees shall commence to accrue on the date of this Agreement
and shall be payable quarterly in arrears on the day following the last Business
Day of each fiscal quarter of Borrowers (as well as on April 1, 2002, and on any
date that the Maximum Credit Amount is reduced) for the immediately preceding
fiscal quarter of the Borrowers (or portion thereof) beginning with the first of
such dates to occur after the date of this Agreement.

                  (d) COMPUTATIONS OF INTEREST AND FEES.

                           (i) All computations of interest and fees (including,
without limitation, Commitment Fees) hereunder shall be made on the basis of the
actual number of days elapsed over a year of 360 days provided that calculations
with respect to the Prime Rate shall be made on the basis of the actual number
of days elapsed in a 365/366 day year.

                           (ii) It is the intent of Borrowers and Bank to
conform to and contract in strict compliance with applicable usury laws from
time to time in effect. All agreements between Borrowers and Bank are hereby
limited by the provisions of this paragraph which shall override and control all
such agreements, whether now existing or hereafter arising. If, from any
possible construction of any of the Loan Documents, interest would otherwise be
payable in excess of the maximum non-usurious amount, any such construction
shall be subject to the provisions of this paragraph and such interest rate
shall be automatically reduced to the maximum non-usurious amount permitted
under applicable law without the necessity of execution of any amendment or new
document.

                  (e) CAPITAL ADEQUACY/ILLEGALITY. If, after the date hereof,
Bank reasonably determines that the adoption or becoming effective of, or any
change in, or any change by any Governmental Authority, central bank or
comparable agency in the interpretation or administration of, any applicable
law, regulation or requirement requiring capital adequacy, or compliance by Bank
with any request or directive regarding capital adequacy of any such
Governmental Authority, central bank or comparable agency, has or would have the
effect of reducing the rate of return on Bank's capital or assets as a
consequence of its commitments or obligations to make Eurodollar Loans hereunder
to a level below that which Bank could have achieved but for such adoption,
effectiveness, change or compliance (taking into consideration Bank's policies
with respect to capital adequacy), upon notice from Bank to Borrowers (which
shall include a detailed written explanation of the circumstances requiring the
notice and the computation of the additional amounts owed), the Borrowers shall
be obligated to pay Bank such additional amount or amounts as will compensate
Bank for such reduction or convert Eurodollar Loans to Base Rate Loans or LIBOR
Floating Rate Loans. If prior to the first day of any Interest Period the Bank
shall have determined that, by reason of circumstances affecting the relevant
market, adequate and reasonable means do not exist for ascertaining the
Eurodollar Rate for such Interest Period, Bank shall promptly give notice
thereof to Borrowers. If such notice is given (a)

                                        9
<PAGE>

any Eurodollar Loans requested to be made on the first day of such Interest
Period shall be made as Base Rate Loans, (b) any Revolving Credit Loans that
were to be converted on the first day of such Interest Period to or continued as
Eurodollar Loans shall be converted to or continued as Base Rate Loans, and (c)
any outstanding Eurodollar Loans shall be converted, on the first day of such
Interest Period, to Base Rate Loans. Notwithstanding any other provision herein,
if the adoption of or any change in any requirement of applicable law or in
interpretation or application thereof shall make it unlawful for Bank to make or
maintain Eurodollar Loans as contemplated by this Agreement, no additional
Eurodollar Loans shall be requested by Borrowers and all then outstanding
Eurodollar Loans, if any, shall be converted automatically to Base Rate Loans.

                  (f) USE OF PROCEEDS. The proceeds of the Revolving Credit
Loans shall be used only for working capital, capital expenditures,
acquisitions, and other lawful corporate purposes.

         3. GENERAL REPRESENTATIONS AND WARRANTIES.  Borrowers hereby jointly
and severally represent and warrant to Bank as follows:

                  (a) GOOD STANDING. Chattem is a corporation, duly organized,

No consent or approval of any Governmental Authority or other Person is required
as a condition to the validity of any Loan Document. Each Borrower is in
compliance with all laws, regulations and governmental requirements to which it
is subject except any noncompliance which in the aggregate would not have a
Material Adverse Effect.

                  (c) BINDING AGREEMENT. This Agreement and the other Loan
Documents executed by Borrowers constitute valid and legally binding obligations
of Borrowers, enforceable in accordance with their terms subject to bankruptcy
and equitable principles.

                  (d) LITIGATION. There is no proceeding involving either
Borrower pending or, to the knowledge of either Borrower, threatened before any
court or other Governmental Authority which if adversely determined would have a
Material Adverse Effect except as disclosed to Bank in writing and acknowledged
by Bank prior to the date of this Agreement.

                                       10
<PAGE>

                  (e) NO CONFLICTING AGREEMENTS. There is no charter, bylaw, or
other document pertaining to the organization, power or authority of either
Borrower and no provision of any existing agreement, mortgage, indenture or
contract binding on either Borrower or affecting any of its property, which
would conflict with or in any way prevent the execution, delivery or carrying
out of the terms of the Loan Documents.

                  (f) TAXES. All taxes and assessments due and payable by either
Borrower have been paid or are being contested in good faith by appropriate
proceedings and each Borrower has filed all tax returns which it is required to

present Borrowers' financial condition as of the date or dates thereof, and
there has been no material adverse change in Borrowers' financial condition or
operations since February 28, 2001. To the best of Borrowers' knowledge, all
material factual information furnished by either Borrower to Bank in connection
with this Agreement and the other Loan Documents is and will be accurate and
complete in all material respects on the date as of which such information is
delivered to Bank and is not and will not be incomplete by the omission of any
material fact necessary to make such information not misleading. Neither
Borrower has any material contingent obligations except as disclosed in the
financial statements heretofore delivered to Bank.

                  (h) PROPERTIES. Except for property tax liens for taxes not
presently due and payable, each Borrower owns and has good title to all of its
properties free and clear of all liens, charges, security interests and other
encumbrances (except purchase money security interests and statutory liens which
secure obligations incurred in the ordinary course of business and which are not
yet due and payable), and neither Borrower has executed any security documents
or financing statements relating to such properties. All of each Borrower's
properties are titled in that Borrower's legal name, and neither Borrower has
used, or filed a financing statement under, any other name for at least the last
five (5) years.

                  (j) CONTINUATION OF REPRESENTATION AND WARRANTIES. All

<PAGE>

                  (d) ADVERSE CONDITIONS OR EVENTS. Borrowers shall promptly

taxes, costs or other expenses arising out of this transaction, as the same
become due and payable, except to the extent the same are being contested in
good faith by appropriate proceedings in a diligent manner.

                  (f) MAINTENANCE. Each Borrower shall maintain all of its
assets in good condition and repair (ordinary wear and tear excepted) and make

standards under ERISA with respect to each and every Plan; file each annual
report required to be filed pursuant to ERISA in connection with each Plan for

Reportable Event that might constitute grounds for termination of any capital

appropriate United States District Court of a trustee to administer any Plan.

deliver to Bank such Loan Documents, and shall perform such other tasks, as Bank
reasonably requests to further carry out the purpose and intent of this
Agreement.

         5. NEGATIVE COVENANTS. Until full payment and performance of all
obligations of Borrower under the Loan Documents, and the expiration of any
obligation of Bank to make additional Revolving Credit Loans, Borrowers agree as
follows:

                                       13
<PAGE>

                  (a) CHARACTER OF BUSINESS. Borrowers will not change the
general character of their business as intended to be conducted at the date
hereof, or engage in any type of business not reasonably related to its business
intended to be conducted. Borrowers will not cease operations, liquidate,
dissolve, merge, acquire or consolidate with any other entity, change either of
their names or transfer or sell any of their assets except in the ordinary
course of business.

                  (b) ENCUMBRANCES/NEGATIVE PLEDGE. Borrowers will not, without
first obtaining the prior written consent of Bank, create or permit to exist any
lien, encumbrance, charge, security interest or negative pledge arrangement on
either Borrower's accounts or inventory, whether now owned or hereafter
acquired. Without limiting the generality of the foregoing, Borrowers will not
permit to exist in favor of any other Person a negative covenant similar to the
one contained in the preceding sentence without first obtaining the prior
written consent of Bank.

         6. DEFAULT. Borrowers shall be in default under this Agreement and
under each of the other Loan Documents if any of the following events of default
(each an "Event of Default") shall occur:

                  (a) Borrowers shall fail to pay any principal, interest or
other sum when due under any Note or any of the other Loan Documents, provided
that Borrowers shall have ten (10) days after they receive written notice from
the Bank of any such failure to cure such failure; or

                  (b) Any representation or warranty made or deemed made by
either Borrower herein or in any other Loan Document or which is contained in

in any material respect on or as of the date made or deemed made; or

                  (c) Either Borrower shall default in the observance or
performance of any covenant, term or agreement contained in any of the Loan

them knows of any such default to cure such default if curable;

                  (d) Either Borrower shall (i) default in any payment of
principal of or interest on any indebtedness beyond the period of grace (not to

subordinated or subordinated notes outstanding), or (ii) default in the
observance or performance of any other covenant, term or agreement relating to
any such indebtedness or contained in any instrument or agreement evidencing or
relating thereto, or any other event shall occur or condition exist, the effect
of which default or other event or condition is to cause, or to permit the
holder or holders of such indebtedness to cause, with the giving of notice if
required, such indebtedness to become due prior to its stated maturity; or

                  (e) Either Borrower shall (i) commence any case, proceeding or
other action under any existing or future law of any jurisdiction, domestic or

relief entered with respect to it, or seeking to adjudicate it a bankrupt or
insolvent, or seeking reorganization, arrangement, adjustment, winding-up,

for a period of 30 days; or (ii) generally not, or shall be unable to, or shall

                  (f) One or more judgments or decrees shall be entered against
either Borrower involving in the aggregate a liability of Five Million Dollars

vacated, discharged, stayed or bonded pending appeal within 30 days from the
entry thereof unless Borrowers have insurance in place to fully satisfy such

business, assets, liabilities (actual or contingent), operations, condition
(financial or otherwise) or prospects of either Borrower, or the existence of
any other condition which Bank reasonably determines to constitute a material
impairment of either Borrower's ability to perform its obligations under the
Loan Documents.

         7. REMEDIES UPON DEFAULT. If an Event of Default shall occur, any
obligation of Bank to make any Revolving Credit Loan shall terminate, Bank may

under each of the Loan Documents as well as all rights, powers and remedies
available at law or in equity. Bank may, upon the occurrence of an Event of
Default, and without notice to Borrowers, apply any property, deposits and other
sums credited by or due from Bank to either Borrower or subject to withdrawal
from the Bank by either Borrower to Borrowers' obligations under the Notes and
the other Loan Documents.

         8. NOTICES. All notices, requests or demands which any party is
required or may desire to give to any other party under any provision of this
Agreement must be in writing delivered to the other party at the following

         633 Chestnut Street
         Chattanooga, Tennessee 37450
         Attention:  Lawrence M. Richey

or to such other address as any party may designate by written notice to the
other party. Each such notice, request and demand shall be deemed given or made
as follows:

                  (a) If sent by hand delivery, upon delivery; and

                  (b) If sent by mail, upon the earlier of the date of receipt
or three (3) days after deposit in the U.S. Mail, first class postage prepaid.

         9. COSTS, EXPENSES AND ATTORNEY'S FEES. Borrowers shall pay to Bank
immediately upon demand the full amount of all costs and expenses, including
reasonable attorneys' fees, incurred by Bank in connection with the enforcement
of the Loan Documents or collection of any amounts outstanding thereunder.

         10. MISCELLANEOUS. Borrower and Bank further covenant and agree as
follows, without limiting any requirement of any other Loan Document:

                  (a) CUMULATIVE RIGHTS AND NO WAIVER. Each and every right
granted to Bank under any Loan Document, or allowed it by law or equity shall be
cumulative of each other and may be exercised in addition to any and all other
rights of Bank, and no delay in exercising any right shall operate as a waiver
thereof, nor shall any single or partial exercise by Bank of any right preclude
any other or future exercise thereof or the exercise of any other right.
Borrowers expressly waive any presentment, demand, protest or other notice of
any kind, including but not limited to notice of intent to accelerate and notice
of acceleration. No notice to or demand on Borrowers in any case shall, of
itself, entitle Borrower to any other or future notice or demand in similar or
other circumstances.

                  (b) APPLICABLE LAW.  This Agreement and the rights and
obligations of the parties hereunder shall be governed by and interpreted in
accordance with the laws of Tennessee and applicable United States federal law.

                  (c) AMENDMENT/SUCCESSORS. No modification, consent, amendment
or waiver of any provision of any Loan Document, nor consent to any departure by
Borrowers therefrom, shall be effective unless the same shall be in writing and
signed by an officer of Bank, and then

                                       16
<PAGE>

shall be effective only in the specified instance and for the purpose for which
given. This Agreement is binding upon Borrowers, their successors and assigns,
and inures to the benefit of Bank, its successors and assigns; however, no
assignment or other transfer of either Borrower's rights or obligations
hereunder shall be made or be effective without Bank's prior written consent,
nor shall it relieve either Borrower of any obligations hereunder. This
Agreement, the Notes and all of the other Loan Documents may be endorsed,
assigned and/or transferred in whole or in part by Bank, and any such holder
and/or assignee of the same shall succeed to and be possessed of the rights and
powers of the Bank under all of the same to the extent transferred and assigned.
Borrowers authorize Bank to disclose to any prospective successor or assignee of
Bank any and all financial and other information in Bank's possession concerning
the Borrowers.

                  (d) DOCUMENTS. All documents, certificates and other items
required under this Agreement to be executed and/or delivered to Bank shall be
in form and content satisfactory to Bank. This Agreement and the other Loan
Documents constitute the entire agreement between the parties with respect to
the subject matter hereof and there are no promises, undertakings,
representations or warranties by the Bank relative to the subject matter hereof
not expressly set forth or referred to herein or the other Loan Documents.

                  (e) PARTIAL INVALIDITY/SEVERABILITY. The unenforceability or
invalidity of any provision of a Loan Document shall not affect the
enforceability or validity of any other provision herein and the invalidity or
unenforceability of any provision of any Loan Document to any Person or
circumstance shall not affect the enforceability or validity of such provision
as it may apply to other Persons or circumstances. If any provision of a Loan
Document would otherwise be unenforceable or invalid as to any Person or
circumstance, then without further action by any party that provision as it
applies with respect to such Person or circumstance shall be deemed modified to
the minimum extent necessary to make that provision fully enforceable and valid.
In any action or proceeding involving bankruptcy, insolvency, reorganization or
other law affecting the rights of creditors generally, if the obligations of any
Borrower would otherwise be held or determined to be invalid or unenforceable on
the account of the amount of its liability under any Loan Document, then
notwithstanding any other provision to the contrary, the amount of such
Borrower's liability shall, without further action by any party, be
automatically limited and reduced to the highest amount which is valid and
enforceable as determined in such action or proceeding. Each Borrower hereby
fully subordinates all claims that Borrower has against the other Borrower with
regard to any amounts paid under this Agreement or any other Loan Document and
agrees not to assert such claims or collect any amounts with respect to such
claims until all obligations under this Agreement and the other Loan Documents
are paid in full and any obligation of Bank to make additional Revolving Credit
Loans has expired or been terminated.

                  (f) SURVIVABILITY. All covenants, agreements, representations
and warranties made herein or in the other Loan Documents shall survive the
making of the Revolving Credit Loans and shall continue in full force and effect
so long as any Revolving Credit Loan is outstanding or the obligation of the
Bank to make any advances under Revolving Credit Loans shall not have expired.

EXHIBIT 4.1

2002 STOCK OPTION PLAN
OF
RPM TECHNOLOGIES, INC.

RPM Technologies, Inc., a Delaware corporation (the "Company"), hereby
adopts the 2002 Stock Option Plan of RPM Technologies, Inc. (the "Plan"),
on this 21st day of February, 2002.  Under this Plan, the Company may grant
options to acquire (the "Options") Three Hundred Thousand (300,000) shares
of its common stock, par value $0.001 (the "stock"), from time to time to
employees of the Company or its subsidiaries, all on the terms and
conditions set forth herein.  In addition, at the discretion of the Board
of Directors, options to acquire stock of the Company may from time to time
be granted under this Plan to other individuals, including consultants or
advisors, who contribute to the success of the Company or its subsidiaries
and are not employees of the Company or its subsidiaries, provided that
bona fide services shall be rendered by consultants and advisors and such
services shall not be in connection with the offer or sale of securities in
a capital-raising transaction and do not directly or indirectly promote or
maintain a market in our securities.

1.	Purpose of this Plan. This Plan is intended to aid the Company in
maintaining and developing a management team, and in attracting new
personnel as needed and to provide such personnel with an incentive to
remain employees of the Company, to use their best efforts to promote the
success of the Company's business, and to provide them with an opportunity
to obtain or increase a proprietary interest in the Company.  It is also
designed to permit the Company to reward those individuals who are not
employees of the Company but who management perceives to have contributed
to the success of the Company, or who are important to the continued
business and operations of the Company.  The above goals will be achieved
through the granting of Options.

2.	Administration of this Plan.  Administration of this Plan shall be
determined by the Company's Board of Directors (the "Board").  Subject to
compliance with applicable provisions of governing law, the Board may
delegate administration of this Plan or specific administrative duties with
respect to this Plan on such terms and to such committees of the Board as
it deems proper (hereinafter the Board or its authorized committee shall be
referred to as "Plan Administrators").  The interpretation and construction
of the terms of this Plan by the Plan Administrators thereof shall be final
and binding on all participants in this Plan absent a showing of
demonstrable error.  No member of the Plan Administrators shall be liable
for any action taken or determination made in good faith with respect to
this Plan.  The grant of any Option approved by a majority vote of those
Plan Administrators attending a duly and properly held meeting shall be
valid.  Any Option approved by the Plan Administrators shall be approved as
specified by the Board at the time of delegation.

3.	Shares of Stock Subject to this Plan.  A total of Three Hundred
Thousand (300,000) shares of Stock may be subject to, or issued pursuant
to, Options granted under this Plan. The number of shares of Stock subject
to, or issued pursuant to, Options granted under this Plan may be increased
or decreased as the Plan Administrators deem advisable.

4.	Reservation of Stock on Granting of Option.  At the time any Option
is granted under the terms of this Plan, the Company will reserve for
issuance the number of shares of Stock subject to such Option until it is
exercised or expires.  The Company may reserve either authorized but
unissued shares or issued shares reacquired by the Company.

5.	Eligibility.  The Plan Administrators may grant Options to
employees, officers, and directors of the Company and its subsidiaries, as
may be existing from time to time, and to other individuals who are not
employees of the Company, or its subsidiaries, including consultants and
advisors, provided that such consultants and advisors render bona fide
services to the Company or its subsidiaries and such services are not
rendered in connection with the offer or sale of securities in a capital-
raising transaction and do not directly or indirectly promote or maintain a
market in our securities.  In any case, the Plan Administrators shall
determine, based on the foregoing limitations and the Company=s best
interests, which employees, officers, directors, consultants and advisors
are eligible to participate in this Plan.  Options shall be in the amounts,
and shall have the rights and be subject to the restrictions, as may be
determined by the Plan Administrators, all as may be within the provisions
of this Plan.

6.	Term of Options and Certain Limitations on Right to Exercise.

a.	Each Option shall have its term established by the Plan
Administrators at the time the Option is granted but in no event may such
term exceed five (5) years.

b.	The term of the Option, once it is granted, may be reduced only as
provided for in this Plan and under the express written provisions of the
Option.

c.	Unless otherwise specifically provided by the written provisions of
the Option or required by applicable disclosure or other legal requirements
promulgated by the Securities and Exchange Commission ("SEC"), no
participant of this Plan or his or her legal representative, legatee, or
distributee will be, or shall be deemed to be, a holder of any shares
subject to an Option unless and until such participant exercises his or her
right to acquire all or a portion of the Stock subject to the Option and
delivers the full exercise price to the Company in accordance with the
terms of this Plan and the Option and then only as to the number of shares
of Stock validly acquired. Except as specifically provided in this Plan or
as otherwise specifically provided by the written provisions of the Option,
no adjustment to the exercise price or the number of shares of Stock
subject to the Option shall be made for dividends or other rights for which
the record date is prior to the date on which the Stock subject to the
Option is acquired by the holder.

d.	The number of shares of Stock subject to an Option shall be
adjusted to take into account any stock splits, stock dividends,
recapitalization of the Stock as provided in the Plan.

e.	Options shall vest and become exercisable at such time or times and
on such terms as the Plan Administrators may determine at the time Options
are granted, subject to this Plan=s requirements and restrictions.

f.	Options may contain such other provisions, including further lawful
restrictions on the vesting and exercise of the Options as the Plan
Administrators may deem advisable.

g.	In no event may an Option be exercised after the expiration of its
term.

h.	Options shall be non-transferable, except by the laws of descent
and distribution.

7.	Exercise Price.  At the time Options are granted, the Plan
Administrators shall establish the exercise price payable to the Company
for shares to be obtained pursuant to Options.

8.	Payment of Exercise Price.  The exercise of any Option shall be
contingent on receipt by the Company of the exercise price paid in either
cash, certified or personal check payable to the Company, or such other
consideration determined appropriate by the Company.

9.	Withholding.  If the grant or exercise of an Option is subject to
withholding or other trust fund payment requirements of the Internal
Revenue Code of 1986, as amended (the "Code"), or applicable state or local
laws, the Company may initially pay the Optionee's liability and be
reimbursed by Optionee no later than six months after such liability arises
and as a condition of accepting Options hereunder, all Optionees hereby
agree to such reimbursement terms.

10.	Dilution or Other Adjustment.  The shares of Stock subject to this
Plan and the exercise price of outstanding Options are subject to
proportionate adjustment in the event of a stock dividend on the Stock or a
change in the number of issued and outstanding shares of Stock as a result
of a stock split, consolidation, or other recapitalization.

11.	Options to Foreign Nationals.   The Plan Administrators may, in
order to fulfill the purpose of this Plan and without amending this Plan,
grant Options to foreign nationals or individuals residing in foreign
countries that contain provisions, restrictions, and limitations different
from those set forth in this Plan and the Options made to United States
residents in order to recognize differences among the countries in law, tax
policy, and custom.  Such grants shall be made in an attempt to give such
individuals essentially the same benefits as contemplated by a grant to
United States residents under the terms of this Plan.

12.	Listing and Registration of Shares.   Each unexercised Option shall
be subject to the requirement that, if at any time, the Plan Administrators
shall determine, in its sole discretion, that it is necessary or desirable
to list, register, or qualify the shares covered by unexercised Options on
any securities exchange or under any state or federal law, or obtain the
consent or approval of any governmental agency or regulatory body as a
condition of, or in connection with, the granting of such Option or the
issuance or purchase of shares thereunder, such Option may not be exercised
in whole or in part unless and until such listing, registration, consent,
or approval shall have been effected or obtained free of any conditions not
acceptable to the Plan Administrators.

13.	Expiration and Termination of this Plan.  This Plan may be
abandoned or terminated at any time by the Plan Administrators except with
respect to any Options then outstanding under this Plan.  This Plan shall
otherwise terminate on the earlier of the date that is five (5) years from
the date first appearing in this Plan or the date on which the three
hundred thousandth (300,000th) share is issued hereunder.

14.	Amendment of this Plan.   This Plan may not be amended more than
once during any six-month period, other than to comport with changes in the
Code or the Employee Retirement Income Security Act or the rules and
regulations promulgated thereunder.  The Plan Administrators may modify and
amend this Plan in any respect; provided, however, that to the extent such
amendment or modification would cause this Plan to no longer comply with
the applicable provisions of the Code governing incentive stock options as
they may be amended from time to time, such amendment or modification shall
also be approved by the shareholders of the Company.
