the rate of interest charged on the Advances shall become effective, without
notice to Borrower, on the effective date of each change in the Prime Rate or
the Maximum Rate, as the case may be; provided, however, if at any time the rate
of interest specified in clause (b) preceding shall exceed the Maximum Rate,
thereby causing the interest on the Advances to be limited to the Maximum Rate,
then any subsequent reduction in the Prime Rate shall not reduce the rate of
interest on the Advances below the Maximum Rate until the aggregate amount of
interest actually accrued on the Advances equals the amount of interest which
would have accrued on the Advances if the interest rate specified in clause (b)
preceding had at all times been in effect. Accrued and unpaid interest on the
Advances shall be payable on the first day of each month commencing on December
1, 2005, and on the Termination Date. If an Event of Default has occurred and is
continuing, all principal of the Advances shall bear interest at the Default
Rate.

     Section 2.5. Requests for Advances. Borrower shall give Lender notice of
each requested Advance by delivery to Lender of an Advance Request Form executed
by an Authorized Representative, properly completed and containing the
information required therein. Borrower may transmit Advance Request Forms by fax
or scanned electronic mail, provided that Borrower holds Lender harmless with
respect to actions taken by Lender based upon Advance Request Forms sent by fax
or scanned electronic mail. Prior to making any Advance, Lender may require that
Borrower deliver a Borrowing Base Certificate dated a recent date acceptable to
Lender. Assuming that each Advance Request Form or request for Advance is in
proper form, if Lender receives an Advance Request Form or request for Advance
prior to 1:00 p.m. on any Business Day, Lender will make the requested Advance
on the same Business Day, and if Lender receives an Advance Request Form or
request for Advance after 1:00 p.m., Lender will make the requested Advance on
the next Business Day.

     Section 2.6. Use of Proceeds. The proceeds of Advances shall be used for
working capital purposes.

     Section 2.7. Mandatory Prepayment. If at any time the outstanding principal
amount of the Advances plus the Letter of Credit Liabilities exceeds the
Borrowing Base, Borrower shall immediately prepay the outstanding Advances by
the amount of the excess plus accrued and unpaid interest on the amount so
prepaid or, if no (or insufficient) Advances are outstanding, Borrower shall
immediately pledge to Lender cash or cash equivalent investments in an amount
equal to the excess as security for the Obligations.

     Section 2.8. Unused Commitment Fee; Reduction or Termination of Commitment.
Borrower agrees to pay to Lender a commitment fee on the average daily unused
portion of the Commitment, from and including the Closing Date to and including
the Termination Date, at the rate of one-fourth of one percent (.25%) per annum
based on a 365 day year and the actual number of days elapsed, payable monthly,
in arrears and on the Termination Date. For the purpose of calculating the
commitment fee hereunder, the Commitment shall be deemed utilized by the amount
of all outstanding Advances and Letter of Credit Liabilities. Borrower shall
have the right at any time to terminate in whole or from time to time to
irrevocably reduce in part the Commitment upon at least three (3) Business Days
prior notice to Lender specifying the effective date thereof, whether a
termination or reduction is being made, and the amount of any partial reduction;
provided, however, the Commitment shall never be reduced below an amount equal
to the outstanding Letter of Credit Liabilities. Simultaneously with giving such
notice, Borrower shall prepay the amount by which the unpaid principal amount of
the Advances plus the outstanding Letter of Credit Liabilities exceeds the
Commitment (after giving effect to such notice) plus accrued and unpaid interest
on the principal amount so prepaid. The Commitment may not be reinstated after
it has been terminated or reduced.

     Section 2.9. Facility Fee. Borrower agrees to pay to Lender a facility fee
in the amount of (a) $18,000.00 on the Closing Date, and (b) $18,000.00 on
October 11, 2006. Such facility fee shall be fully earned when paid.

     Section 2.10. Letters of Credit. Subject to the terms and conditions of
this Agreement, Lender agrees to issue one or more Letters of Credit for the
account of Borrower from time to time from the date hereof to and including the
Termination Date; provided, however, that the outstanding Letter of Credit
Liabilities shall not at any time exceed the least of (a) $500,000.00, (b) an
amount equal to the Commitment minus the outstanding Advances, or (c) the
Borrowing Base minus the outstanding Advances. Each Letter of Credit shall have
an expiration date which shall not be more than two (2) years from the date of
issuance of such Letter of Credit, shall have an expiration date which is at
least five (5) Business Days prior to


                                      -9-
<PAGE>

the Termination Date, shall be payable in United States dollars, shall support a
transaction that is entered into in the ordinary course of Borrower's business,
and shall otherwise be satisfactory in form and substance to Lender. No Letter
of Credit shall require any payment by Lender to the beneficiary thereunder
pursuant to a drawing prior to the third Business Day following presentment of a
draft and any related documents to Lender.

     Section 2.11. Procedure for Issuing Letters of Credit. Each Letter of
Credit shall be issued upon receipt by Lender of written notice from an
Authorized Representative requesting the issuance of such Letter of Credit,
which notice shall be received by Lender at least three (3) Business Days prior
to the requested date of issuance of such Letter of Credit. Such notice shall be
accompanied by Lender's standard application for issuance of Letters of Credit
(commercial or standby) as then in effect and such other documents and
instruments as Lender may require. Such notice and application (both front and
back sides) may be sent by fax, provided that Borrower holds Lender harmless
with respect to actions taken by Lender based upon notices and applications sent
by fax. Each request for a Letter of Credit shall constitute a representation by
Borrower to Lender as to each of the matters set forth in the Borrowing Base
Certificate, including representations that (a) the sum of (i) the outstanding
Advances plus (ii) the Letter of Credit Liabilities plus (iii) the face amount
of the requested Letter of Credit does not exceed the lesser of the Borrowing
Base or the Commitment, and (b) no Event of Default exists. Prior to Issuing any
Letter of Credit, Lender may request a Borrowing Base Certificate from Borrower
dated of a recent date acceptable to Lender evidencing that the statements
contained in the preceding sentence are correct.

     Section 2.12. Payments Constitute Advances. Each payment by Lender pursuant
to a drawing under a Letter of Credit shall constitute and be deemed an Advance
by Lender to Borrower under the Note and this Agreement as of the day and time
such payment is made by Lender and in the amount of such payment.

     Section 2.13. Letter of Credit Fees. Borrower shall pay to Lender a letter
of credit fee payable on the date each Letter of Credit is issued in an amount
equal to the greater of (a) one and one-fourth of one percent (1.25%) per annum
of the stated amount of such Letter of Credit for the period during which such
Letter of Credit will remain outstanding, based on a 360 day year and the actual
number of days elapsed, and (b) $350.00. In addition, Borrower shall pay to
Lender (a) at the time of issuance of any Letter of Credit, all out-of-pocket
costs incurred by Lender in connection with the issuance of such Letter of
Credit (b) upon the payment of any Letter of Credit, all applicable payment
fees, and (c) upon the amendment (including the extension) of any Letter of
Credit, all applicable amendment fees.

     Section 2.14. Obligations Absolute. The obligations of Borrower under this
Agreement and the other Loan Documents, including without limitation the
obligation of Borrower to reimburse Lender for payment of drawings under any
Letter of Credit, shall be absolute, unconditional and irrevocable, and shall be
performed strictly in accordance with the terms of this Agreement and the other
Loan Documents under all circumstances, including (a) any lack of validity or
enforceability of any Letter of Credit or any other Loan Document, (b) the
existence of any claim, set-off, counterclaim, defense or other rights which
Borrower, any Obligated Party or any other Person may have at any time against
any beneficiary of any Letter of Credit, Lender, or any other Person, whether in
connection with this Agreement or any other Loan Document or any unrelated
transaction, (c) if any statement, draft or other document presented under any
Letter of Credit proves to be forged, fraudulent, invalid or insufficient in any
respect or any statement therein is untrue or inaccurate in any respect
whatsoever, (d) payment by Lender under any Letter of Credit against
presentation of a draft or other document which does not comply with the terms
of such Letter of Credit in a manner which is not material, (e) any amendment or
waiver of, or any consent to departure from, any


                                      -10-

<PAGE>

Loan Document or (f) any other circumstance or happening whatsoever, whether or
not similar to any of the foregoing.

     Section 2.15. Limitation of Liability. Borrower assumes all risks of the
acts or omissions of any beneficiary of any Letter of Credit with respect to its
use of such Letter of Credit. Neither Lender or any of its officers, employees
or directors shall have any responsibility or liability to Borrower or any other
Person for (a) the failure of any draft to bear any reference or adequate
reference to any Letter of Credit, or the failure of any documents to accompany
any draft at negotiation, or the failure of any Person to surrender or to take
up any Letter of Credit or to send documents apart from drafts as required by
the terms of any Letter of Credit, or the failure of any Person to note the
amount of any instrument on any Letter of Credit, each of which requirements, if
contained in any Letter of Credit itself, it is agreed may be waived by Lender,
(b) errors, omissions, interruptions or delays in transmission or delivery of
any messages, (c) the validity, sufficiency or genuineness of any draft or other
document, or any endorsement thereon, even if any such draft, document or
endorsement should in fact prove to be in any and all respects invalid,
insufficient, fraudulent or forged or any statement therein is untrue or
inaccurate in any respect, (d) the payment by the Lender to the beneficiary of
any Letter of Credit against presentation of any draft or other document that
does not comply with the terms of the Letter of Credit in a respect which is not
material or (e) any other circumstance whatsoever in making or failing to make
any payment under a Letter of Credit. Lender may accept documents that appear on
their face to be in order, without responsibility for further investigation,
regardless of any notice or information to the contrary. Notwithstanding the
foregoing, Lender shall be liable to Borrower to the extent of any direct, but
not consequential, damages suffered by Borrower which Borrower proves in a final
nonappealable judgment were caused by (i) Lender's willful misconduct or gross
negligence in determining whether documents presented under any Letter of Credit
complied with the terms thereof or (ii) Lender's willful failure to pay under
any Letter of Credit after presentation to it of documents strictly complying
with the terms and conditions of such Letter of Credit.

     Section 2.16. Provisions Regarding Electronic Issuance of Letters of
Credit. Lender may adopt procedures pursuant to which Borrower may request the
issuance of Letters of Credit by electronic means and Lender may issue Letters
of Credit based on such electronic requests. Such procedures may include the
entering by Borrower into the Letter of Credit Applications electronically. All
the procedures, actions and documents referred to in the two preceding sentences
are referred to as "Electronic Applications". Borrower holds Lender harmless
with respect to actions taken by Lender based upon Electronic Applications.
Borrower further agrees to be bound by all the terms and provisions contained in
the Letter of Credit Applications, including, without limitation, the terms and
provisions of the Letter of Credit Applications contained on the reverse side of
the paper copies thereof, including the release and indemnification provisions
contained therein.

under this Agreement, the Note or any other Loan Document shall be stated to be
due on a day that is not a Business Day, such payment may be made on the next
Business Day, and interest shall continue to accrue during such extension.

evidenced by the Note shall be computed on the basis of a year of 365 or 366

result of any Regulatory Change there shall be imposed, modified, or deemed
applicable any tax, reserve, special deposit, or similar requirement against or
with respect to or measured by reference to Letters of Credit issued or to be
issued hereunder or Lender's Commitment to issue Letters of Credit hereunder,
and the result shall be to increase the cost to Lender of issuing or maintaining
any Letter of Credit or its Commitment to issue Letters of Credit hereunder or
reduce any amount receivable by Lender hereunder in respect of any Letter of
Credit (which increase in cost, or reduction in amount receivable, shall be the
result of Lender's reasonable allocation of the aggregate of such increases or
reductions resulting from such event), then, upon demand by Lender, Borrower
agrees to pay to Lender from time to time as specified by Lender, such
additional amounts as shall be sufficient to compensate Lender for such
increased costs or reductions in amount. A statement as to such increased costs
or reductions in amount incurred by Lender, submitted by Lender to Borrower,
shall be conclusive as to the amount thereof, provided that the determination
thereof is made on a reasonable basis.

ABOVE, ANY CLAIM WHICH ARISES AS A RESULT OF THE NEGLIGENCE OF LENDER; PROVIDED,
HOWEVER, THAT BORROWER'S INDEMNIFICATION OBLIGATIONS UNDER THIS SECTION 11.2
SHALL NOT APPLY TO THE EXTENT THAT THE CLAIMS ARISE AS A RESULT OF THE
NEGLIGENCE OR WILLFUL MISCONDUCT OF ANY INDEMNIFIED PERSON.

     Section 11.3. Limitation of Liability. Neither Lender nor any affiliate,

     Section 11.4. No Waiver; Cumulative Remedies. No failure on the part of
Lender to exercise and no delay in exercising, and no course of dealing with
respect to, any right, power, or privilege under this Agreement shall operate as
a waiver thereof, nor shall any single or partial exercise of any right, power,
or privilege under this Agreement preclude any other or further exercise thereof
or the exercise of any other right, power, or privilege. The rights and remedies
provided for in this Agreement and the other Loan Documents are cumulative and
not exclusive of any rights and remedies provided by law.

     Section 11.5. Successors and Assigns. This Agreement is binding upon and
shall inure to the benefit of Lender and Borrower and their respective
successors and assigns, except that Borrower may not assign or transfer any of
its rights or obligations under this Agreement without prior written consent of
Lender.

     Section 11.6. Survival. All representations and warranties made in this
Agreement or any other Loan Document or in any document, statement, or
certificate furnished in connection with this Agreement shall survive the
execution and delivery of this Agreement and the other Loan Documents, and no
investigation by Lender or any closing shall affect the representations and
warranties or the right of Lender to rely upon them. Without prejudice to the
survival of any other obligation of Borrower hereunder, the obligations of
Borrower under Sections 11.1 and 11.2 shall survive repayment of the Note and
termination of the Commitment and the Letters of Credit.

     Section 11.7. Amendment. The provisions of this Agreement and the other
Loan Documents to which Borrower is a party may be amended or waived only by an
instrument in writing signed by the parties hereto.

     Section 11.8. Maximum Interest Rate. No provision of this Agreement or of
any other Loan Documents shall require the payment or the collection of interest
in excess of the maximum permitted by applicable law. If any excess of interest
in such respect is hereby provided for, or shall be adjudicated to be so
provided, in any other Loan Documents or otherwise in connection with this loan
transaction, the provisions of this Section shall govern and prevail and neither
Borrower nor the sureties, guarantors, successors, or assigns of Borrower shall
be obligated to pay the excess amount of such interest or any other excess sum
paid for the use, forbearance, or detention of sums loaned pursuant hereto. In
the event Lender ever receives, collects, or applies as interest any such sum,
such amount which would be in excess of the maximum amount permitted by
applicable law shall be applied as a payment and reduction of the principal of
the indebtedness evidenced by the Note; and, if the principal of the Note has
been paid in full, any remaining excess shall forthwith be paid to Borrower. In
determining whether or not the interest paid or payable exceeds the Maximum
Rate, Borrower and Lender shall, to the extent permitted by applicable law, (a)
characterize any non-principal payment as an expense, fee, or premium rather
than as interest, (b) exclude voluntary prepayments and the effects thereof, and
(c) amortize, prorate, allocate, and spread in equal or unequal parts the total
amount of interest throughout the entire contemplated term of the indebtedness
evidenced by the Note so that interest for the entire term does not exceed the
Maximum Rate.

     Section 11.9. Notices. (a) All notices and other communications provided
for in this Agreement and the other Loan Documents shall be in writing and may
(subject to paragraph (b) below) be telecopied (faxed), mailed by certified mail
return receipt requested, or delivered by hand or overnight courier service to
the intended recipient at the addresses specified below or at such other address
as shall be designated by any party listed below in a notice to the other

jurisdiction of such courts and waives any objection it may now or hereafter
have as to the venue of any such action or proceeding brought in any such court
or that any such court is an inconvenient forum. Borrower agrees that service of
process upon it may be made by certified or registered mail, return receipt
requested, at its office specified in this Agreement. Except as provided in the

other Loan Documents shall affect the right of Lender to serve process in any
other manner permitted by law or shall limit the right of Lender to bring any

any action or proceeding by Borrower against Lender shall be brought only in a

any time and from time to time to sell or transfer one or more participation
interests in the Note and the indebtedness evidenced thereby to one or more
purchasers ("Purchasers"), whether related or unrelated to Lender. Lender may
provide to any one or more Purchasers or potential Purchasers any information,
financial statements, data or knowledge Lender may have about Borrower or about
any other matter relating to the Obligations, and Borrower waives any rights to
privacy it may have with respect to such matters. Borrower further waives any
and all notices of sale of participation interests and notices of repurchases of
participation interests. Borrower agrees that the owners of any participation
interests will be considered as the absolute owners of their interests in the
Obligations and will have all the rights granted under the participation
agreements or other agreements governing the sale of their participation
interests. Borrower waives all rights of offset or counterclaim that it may now
or later have against Lender or against any Purchaser and agrees that either
Lender or any Purchaser may enforce Borrower's obligations under the Loan
