                  SERIES C SENIOR CONVERTIBLE PREFERRED STOCK
                                       OF
                               OPTIUM CORPORATION

                           VOID AFTER JANUARY 31, 2013

          This Warrant is issued to William Krimmel or his registered assigns
(the "Employee") by Optium Corporation, a Delaware corporation (including any
successors as provided herein, the "Company"), on May 1, 2003 (the "Warrant
Issue Date"). This Warrant is issued to the Employee in connection with his
employment by the Company.

          1.   NUMBER OF SHARES SUBJECT TO WARRANT; EXERCISE PRICE. Subject to
the terms and conditions hereinafter set forth, the Employee is entitled, upon
surrender of this Warrant at the principal office of the Company, to purchase
from the Company 5,801 shares (the "Shares") of Series C Senior Convertible
Preferred Stock, par value $0.0001 per share (the "Series C Preferred Stock"),
at a purchase price of $0.05036 per share (as may be adjusted herein, the
"Exercise Price").

          2.   VESTING; EXERCISE PERIOD. Except as otherwise provided for
herein, this Warrant shall be exercisable, in whole or in part, at any time and
from time to time beginning on the earlier of (i) December 31, 2003 or (ii) the
moment in time that is immediately prior to the consummation of a Change in
Control (as defined in the Company's 2001 Stock Incentive Plan, as amended) and
ending at 5:00 p.m. eastern time on the tenth (10th) anniversary of the Warrant
Issue Date (the "Warrant Termination Date"); PROVIDED, that if the employment by
the Company of the Employee is terminated for any reason or reasons prior to
this Warrant becoming exercisable, then this Warrant shall expire without ever
becoming exercisable; and, PROVIDED FURTHER, that if the employment by the
Company of the Employee is terminated for any reason or reasons after this
Warrant first becomes exercisable, then this Warrant shall expire and no longer
be exercisable on the earlier of: the Warrant Termination Date or (ii) the date
that is ninety (90) days following the date of such termination.

          3.   NOTICE OF SALE OR CONVERSATION. The Company shall provide written
notice to the Employee not less than thirty (30) days prior to the consummation
of a Change in

<Page>

Control or any transaction that would cause the conversion of all outstanding
shares of Series C Preferred Stock into Common Stock of the Company.

          4.   METHOD OF EXERCISE. While this Warrant remains outstanding and
exercisable in accordance with SECTION 2 hereof, the purchase rights hereby
represented may be exercised in whole but not in part, at the election of the
Employee, by the tender of the Notice of Exercise in substantially the form
attached hereto as EXHIBIT A and the surrender of this Warrant at the principal
office of the Company and by the payment to the Company in cash, by check,
cancellation of indebtedness, shares of Series C Preferred Stock that have been
held by the Employee for at least six (6) months (or shares previously issued
upon conversion thereof) or other form of payment acceptable to the Company, of
an amount equal to the then applicable Exercise Price multiplied by the number
of Shares then being purchased. For purposes of this SECTION 4, the fair market
value of a share of Series C Preferred Stock (or shares previously issued upon
conversion thereof) as of a particular date shall be determined by the Company's
Board of Directors in its reasonable discretion; PROVIDED that if such shares
issuable upon exercise of this Warrant are traded on a national securities
exchange or admitted to quotation on the National Association of Securities
Dealers Automated Quotation System, the fair market value on any given date
shall be the average of the closing sale prices on such exchange or system of
such shares issuable upon exercise of this Warrant for the 20 trading days
preceding such date.

          5.   CERTIFICATES FOR SHARES. Upon the exercise of the purchase rights
evidenced by this Warrant, one or more certificates for the number of Shares so
purchased shall be issued as soon as practicable thereafter (with appropriate
restrictive legends, as applicable).

          6.   ADJUSTMENT OF EXERCISE PRICE AND NUMBER OF SHARES. The number of
and kind of securities purchasable upon exercise of this Warrant and the
Exercise Price shall be subject to adjustment from time to time as follows:

               (a) SUBDIVISIONS, COMBINATIONS AND OTHER ISSUANCES. If the
Company shall at any time prior to the exercise or expiration of this Warrant
subdivide its shares of Series C Preferred Stock (or any successor security as
provided for in SECTION 6(b)), by split-up or otherwise, or combine its shares
of Series C Preferred Stock (or any successor security as provided for in
SECTION 6(b)), or issue additional Common Stock as a dividend with respect to
any of its shares of Series C Preferred Stock (or any successor security as
provided for in SECTION 6(b)), the number of Shares issuable on the exercise of
this Warrant shall forthwith be proportionately increased in the case of a
subdivision or stock dividend, or proportionately decreased in the case of a
combination. Appropriate adjustments shall also be made to the Exercise Price,
provided that the aggregate exercise price payable hereunder for the total
number of Shares purchasable under this Warrant (as adjusted) shall remain the
same. Any adjustment under this SECTION 6(a) shall become effective at the close
of business on the date the subdivision or combination becomes effective, or as
of the record date of such dividend, or in the event that no record date is
fixed, upon the making of such dividend.

                                       -2-
<Page>

               (b)  RECLASSIFICATION, REORGANIZATION AND CONSOLIDATION. In the
event of any corporate reclassification, capital reorganization, consolidation,
spin-off or change in the shares of Series C Preferred Stock (other than as a
result of a subdivision, combination, or dividend provided for in SECTION 6(a)
above), then, as a condition of such event, lawful provision shall be made, and
duly executed documents evidencing the same from the Company or its successor
shall be delivered to the Employee, so that the Employee shall have the right at
any time prior to the expiration of this Warrant to purchase, at a total price
equal to that payable upon the exercise of this Warrant, the kind and amount of
shares of stock and/or other securities and property receivable in connection
with such event by a Employee of the same number of shares for which this
Warrant could have been exercised immediately prior to such event. In any such
case appropriate provisions shall be made with respect to the rights and
interest of the Employee so that the provisions hereof shall thereafter be
applicable with respect to any shares of stock or other securities and property
deliverable upon exercise hereof, and appropriate adjustments shall be made to
the Exercise Price, provided that the aggregate exercise price payable hereunder
for the total number of Shares purchasable under this Warrant (as adjusted)
shall remain the same.

               (c)  NOTICE OF ADJUSTMENT. When any adjustment is required to be
made to the Exercise Price or in the number or kind of Shares purchasable upon
exercise of the Warrant, the Company shall promptly notify the Employee of such
event and of the adjusted Exercise Price or number of Shares or other securities
or property thereafter purchasable upon exercise of this Warrant.

          7.   ASSUMPTION OF WARRANT. If at any time while this Warrant, or any
portion thereof, is outstanding and unexpired there shall be an acquisition of
the Company by another entity by means of a merger, reorganization or
consolidation of the Company or any other similar transaction, then, as a part
of such acquisition, lawful provision shall be made so that the Employee shall
thereafter be entitled to receive upon exercise of this Warrant, during the
period specified herein and upon payment of the aggregate Exercise Price then in
effect, the number of shares of stock or other securities or property of the
successor corporation resulting from such acquisition which the Employee would
have been entitled to receive in such acquisition if this Warrant had been
exercised immediately before such acquisition.

          8.   NO FRACTIONAL SHARES OR SCRIP. No fractional Shares or scrip
representing fractional Shares shall be issued upon the exercise of this
Warrant, but in lieu of such fractional Shares the Company shall make a cash
payment therefor on the basis of the fair market value determined in accordance
with SECTION 4.

          9.   NO SHAREHOLDER RIGHTS. Prior to exercise of this Warrant, the
Employee shall not be entitled to any rights of a shareholder with respect to
the Shares, including (without limitation) the right to vote such Shares,
receive dividends or other distributions thereon, exercise preemptive rights or
be notified of shareholder meetings, and such Employee shall not be entitled to
any notice or other communication concerning the business or affairs of the
Company. However, nothing in this SECTION 9 shall limit the right of the
Employee to be provided the notices required under this Warrant.

between SILICON VALLEY BANK ("Bank"), whose address is 3003 Tasman Drive, Santa
Clara, California 95054 and having a loan production office at 5 Radnor Corp.

CORPORATION, a corporation organized and in good standing in the State of
Delaware ("Borrower"), whose address is 500 Horizon Drive, Clalfont,
Pennsylvania, 18914 provides the terms on which Bank will lend to Borrower and
Borrower will repay Bank. The parties agree as follows:

1.   ACCOUNTING AND OTHER TERMS

     Accounting terms not defined in this Agreement will be construed following
GAAP. Calculations and determinations must be made following GAAP. The term
"financial statements" includes the notes and schedules. The terms "including"
and "includes" always mean "including (or includes) without limitation," in this
or any Loan Document.

2.   LOAN AND TERMS OF PAYMENT

2.1  PROMISE TO PAY.

     Borrower promises to pay Bank the unpaid principal amount of all Credit
Extensions and interest on the unpaid principal amount of the Credit Extensions.

2.1.1 REVOLVING ADVANCES.

     (a) Bank will make Advances not exceeding (i) the lesser of (A) the
Committed Revolving Line minus all amounts for services utilized under the Cash
Management Services Sublimit, (ii) the amount of all outstanding Letters of
Credit (including drawn but unreimbursed Letters of Credit), and minus (iii) the
FX Reserve (collectively, the "Sublimit Outstandings") or (B) the Borrowing
Base, minus the Sublimit Outstandings. Amounts borrowed under this Section may
be repaid and reborrowed during the term of this Agreement. All advances shall
be evidenced by the Revolving Promissory Note to be executed and delivered by
Borrower to Bank on the Closing Date and shall be repaid in accordance with the
terms of the Revolving Promissory Note.

     (b) To obtain an Advance, Borrower must notify Bank by facsimile or
telephone by 3:00 p.m. Eastern time on the Business Day the Advance is to be
made. Borrower must promptly confirm the notification by delivering to Bank the
Loan Payment/Advance Request Form attached as EXHIBIT B (the "Payment/Advance
Form"). Bank will credit Advances to Borrower's deposit account. Bank may make
Advances under this Agreement based on instructions from a Responsible Officer
or his or her designee or without instructions if the Advances are necessary to
meet Obligations which have become due. Bank may rely on any telephone notice
given by a person whom Bank believes is a Responsible Officer or designee.
Borrower will indemnify Bank for any loss Bank suffers due to such reliance.

     (c) The Committed Revolving Line terminates on the Revolving Maturity Date,
when all Advances are immediately payable.

     (d) Bank's obligation to lend the undisbursed portion of the Obligations
will terminate if, in Bank's sole discretion, there has been a material adverse
change in the general affairs, management, results of operation, condition
(financial or otherwise) or the prospect of repayment of the Obligations, or
there has been any material adverse deviation by Borrower from the most recent
business plan of Borrower presented to and accepted by Bank prior to the
execution of this Agreement.

2.1.2 LETTERS OF CREDIT SUBLIMIT.

     Bank will issue or have issued Letters of Credit for Borrower's account not
exceeding (i) the lesser of the Committed Revolving Line or the Borrowing Base,
minus the Sublimit Outstandings; however, the face amount of outstanding Letters
of Credit (including drawn but unreimbursed Letters of Credit) and Sublimit
Outstandings may not at any time exceed Five Hundred Thousand Dollars
($500,000). Each Letter of Credit will have an expiry date of no later than one
hundred eighty (180) days after the Revolving Maturity Date, but Borrower's
obligations to reimburse Bank under the Letters of Credit will be secured by
cash on terms acceptable to Bank at any time after the Revolving Maturity Date
if the term of this Agreement is not extended by Bank. Borrower agrees to
execute any further

<Page>

documentation in connection with the Letters of Credit as Bank may reasonably
request. Prior to or simultaneously with the opening of each Letter of Credit,
Borrower shall pay to Bank, its standard letter of credit fees (each a "Letter
of Credit Fee" and collectively the "Letter of Credit Fees"). Such Letter of
Credit Fees shall be paid in advance upon the issuance of the Letter of Credit
and upon each anniversary thereof, if any. In addition, Borrower shall pay to
Bank any and all additional issuance, negotiation, processing, transfer or other
fees to the extent and as and when required by Bank.

2.1.3 FOREIGN EXCHANGE SUBLIMIT.

     If there is availability under the Committed Revolving Line and the
Borrowing Base, then Borrower may enter in foreign exchange forward contracts
with the Bank under which Borrower commits to purchase from or sell to Bank a
set amount of foreign currency more than one business day after the contract
date (the "FX Forward Contract"). Bank will subtract 10% of each outstanding FX
Forward Contract from the foreign exchange sublimit which together with all
Sublimit Outstandings is a maximum of Five Hundred Thousand Dollars ($500,000)
(the "FX Reserve"). The total FX Forward Contracts at any one time may not
exceed 10 times the amount of the FX Reserve. Bank may terminate the FX Forward
Contracts if an Event of Default occurs.

2.1.4 CASH MANAGEMENT SERVICES SUBLIMIT.

     Borrower may use up to Five Hundred Thousand Dollars ($500,000) for Bank's
Cash Management Services, which may include merchant services, direct deposit of
payroll, business credit card, and check cashing services identified in various
cash management services agreements related to such services (the "Cash
Management Services"), provided that the aggregate amount of all Cash management
Services and Sublimit Outstandings can not exceed Five Hundred Thousand Dollars
($500,000). Such aggregate amounts utilized under the Cash Management Services
Sublimit will at all times reduce the amount otherwise available to be borrowed
under the Committed Revolving Line. Any amounts Bank pays on behalf of Borrower
or any amounts that are not paid by Borrower for any Cash Management Services
will be treated as Advances under the Committed Revolving Line and will accrue
interest at the rate for Advances.

2.1.5 EQUIPMENT ADVANCES.

     (a) Through September 30, 2004 (the "Equipment Availability End Date"),
Bank will make advances ("Equipment Advance" and, collectively, "Equipment
Advances") not exceeding the Committed Equipment Line. The Equipment Advances
may only be used to finance Equipment purchased on the date of each Equipment
Advance and may not exceed one hundred percent (100%) of the equipment invoice,
excluding taxes, shipping, warranty charges, freight discounts and installation
expense. Software may constitute up to twenty five percent (25%) of the
aggregate Equipment Advances. Each Equipment Advance must be for a minimum of
Fifty Thousand Dollars ($50,000). The number of Equipment Advances is limited to
six (6).

     (b) Interest accrues from the date of each Equipment Advance at the rate in
Section 2.3 (a) and is payable monthly. Equipment Advances outstanding on the
Equipment Availability End Date are payable in thirty (30) equal monthly
installments of principal, plus accrued interest, beginning on the first (1st)
day of each month commencing on October 1, 2004 and ending on April 1, 2007 (the
"Equipment Maturity Date"). All Equipment Advances shall be evidenced by the
Equipment Term Note to be executed and delivered by Borrower to Bank on the
Closing. Equipment Advances when repaid may not be reborrowed.

     (c) To obtain an Equipment Advance, Borrower must notify Bank (the notice
is irrevocable) by facsimile no later than 3:00 p.m. Eastern time one (1)
Business Day before the day on which the Equipment Advance is to be made. The
notice in the form of EXHIBIT B (Payment/Advance Form) must be signed by a
Responsible Officer or designee and include a copy of the invoice for the
Equipment being financed.

2.2  OVERADVANCES.

     If Borrower's Obligations under Sections 2.1.1, 2.1.2, 2.1.3 and 2.1.4
exceed the lesser of either (i) the Committed Revolving Line or (ii) the
Borrowing Base, Borrower shall immediately pay Bank the excess.

2.3  INTEREST RATE, PAYMENTS.

     (a) Interest Rate. (i) Advances accrue interest on the outstanding
principal at a per annum rate of one and three quarters of one (1.75) percentage
point above the Prime Rate, until such time as Borrower has EBITDA in excess of
$1.00 as of any quarter end and commencing on the first day of the first
calendar quarter thereafter at the rate of at one and one quarter (1.25)
percentage point in excess of the Prime Rate. (ii) Equipment Advances accrue
interest on the outstanding principal balance at a per annum rate of two and one
half (2.5) percentage points above the Prime Rate. After and during the
continuance of an Event of Default, Obligations accrue interest at five percent
(5%) above the rate effective immediately before the Event of Default. The
interest rate increases or decreases when the Prime Rate changes. Interest is
computed on a 360 day year for the actual number of days elapsed.

     (b) Payments. Interest due on the Committed Revolving Line is payable on
the fifth (5th) day of each month. Interest due on the Equipment Advances is
payable on the first (1st) day of each month. Bank may debit any of Borrower's
deposit accounts including Account Number __________________________________ for
principal and interest payments owing or any amounts Borrower owes Bank. Bank
will promptly notify Borrower when it debits Borrower's accounts. These debits
are not a set-off. Payments received after 12:00 noon Eastern time are
considered received at the opening of business on the next Business Day. When a
payment is due on a day that is not a Business Day, the payment is due the next

9.1  RIGHTS AND REMEDIES.

     When an Event of Default occurs and continues Bank may, without notice or
demand, do any or all of the following:

     (a) Declare all Obligations immediately due and payable (but if an Event of
Default described in Section 8.5 occurs all Obligations are immediately due and
payable without any action by Bank);

     (b) Stop advancing money or extending credit for Borrower's benefit under
this Agreement or under any other agreement between Borrower and Bank;

     (c) Settle or adjust disputes and claims directly with account debtors for
amounts, on terms and in any order that Bank considers advisable;

     (d) Make any payments and do any acts it considers necessary or reasonable
to protect its security interest in the Collateral. Borrower will assemble the
Collateral if Bank requires and make it available as Bank designates. Bank may
enter premises where the Collateral is located, take and maintain possession of
any part of the Collateral, and pay, purchase, contest, or compromise any Lien
which appears to be prior or superior to its security interest and pay all
expenses incurred. Borrower grants Bank a license to enter and occupy any of its
premises, without charge, to exercise any of Bank's rights or remedies;

     (e) Apply to the Obligations any (i) balances and deposits of Borrower with
Bank or its Affiliate it holds, or (ii) amount held by Bank owing to or for the
credit or the account of Borrower;

     (f) Ship, reclaim, recover, store, finish, maintan, repair, prepare for
sale, advertise for sale, and sell the Collateral. Bank is granted a
non-exclusive, royalty-free license or other right to use, without charge,
Borrower's labels, Patents, Copyrights, rights of use of any name, trade
secrets, trade names, Trademarks, service marks, and advertising matter, or any
similar property as it pertains to the Collateral, in completing production of,
advertising for sale, and selling any Collateral and, in connection with Bank's
exercise of its rights under this Section, Borrower's rights under all licenses
and all franchise agreements inure to Bank's benefit; and

     (g) Dispose of the Collateral according to the Code.

9.2  POWER OF ATTORNEY.

     Effective only when an Event of Default occurs and continues. Borrower
irrevocably appoints Bank as its lawful attorney to: (i) endorse Borrower's name
on any checks or other forms of payment or security; (ii) sign Borrower's name
on any invoice or bill of lading for any Account or drafts against account
debtors, (iii) make, settle, and adjust all claims under Borrower's insurance
policies; (iv) settle and adjust disputes and claims about the Accounts directly
with account debtors, for amounts and on terms Bank determines reasonable; and
(v) transfer the Collateral into the name of Bank or a third party as the Code
permits. Bank may exercise the power of attorney to sign Borrower's name on any
documents necessary to perfect or continue the perfection of any security
interest regardless of whether an Event of Default has occurred. Bank's
appointment as Borrower's attorney in fact, and all of Bank's

                                        9

<Page>

rights and powers, coupled with an interest, are irrevocable until all
Obligations have been fully repaid and performed and Bank's obligation to
provide Credit Extensions terminates.

9.3  ACCOUNTS COLLECTION.

     When an Event of Default occurs and continues, Bank may notify any Person
owing Borrower money of Bank's security interest in the funds and verify the
amount of the Account. Borrower must collect all payments in trust for Bank and,
if requested by Bank, immediately deliver the payments to Bank in the form
received from the account debtor, with proper endorsements for deposit.

9.4  BANK EXPENSES.

     If Borrower fails to pay any amount or furnish any required proof of
payment to third persons, Bank may make all or part of the payment or obtain
insurance policies required in Section 6.5, and take any action under the
policies Bank deems prudent. Any amounts paid by Bank are Bank Expenses and
immediately due and payable, bearing interest at the then applicable rate and
secured by the Collateral. No payments by Bank are deemed an agreement to make
similar payments in the future or Bank's waiver of any Event of Default.

9.5  BANK'S LIABILITY FOR COLLATERAL.

     If Bank complies with reasonable banking practices and the Code, it is not
liable for: (a) the safekeeping of the Collateral; (b) any loss or damage to the
Collateral; (c) any diminution in the value of the Collateral; or (d) any act or
default of any carrier, warehouseman, bailee, or other person. Borrower bears
all risk of loss, damage or destruction of the Collateral.

9.6  REMEDIES CUMULATIVE.

     Bank's rights and remedies under this Agreement, the Loan Documents, and
all other agreements are cumulative. Bank has all rights and remedies provided
under the Code, by law, or in equity. Bank's exercise of one right or remedy is
not an election, and Bank's waiver of any Event of Default is not a continuing
waiver. Bank's delay is not a waiver, election, or acquiescence. No waiver is
effective unless signed by Bank and then is only effective for the specific
instance and purpose for which it was given.

9.7  DEMAND WAIVER.

     Borrower waives demand, notice of default or dishonor, notice of payment
and nonpayment, notice of any default, nonpayment at maturity, release,
compromise, settlement, extension, or renewal of accounts, documents,
instruments, chattel paper, and guarantees held by Bank on which Borrower is
liable.

10.  NOTICES

related agreement must be in writing and be personally delivered or sent by an
overnight delivery service, by certified mail, postage prepaid, return receipt
requested, or by telefacsimiie to the addresses set forth at the beginning of
this Agreement. A party may change its notice address by giving the other party
written notice.

11.  CHOICE OF LAW. VENUE AND JURY TRIAL WAIVER

     Pennsylvania law governs the Loan Documents without regard to principles of
conflicts of law. Borrower and Bank each submit to the exclusive jurisdiction of
the State and Federal courts in the Commonwealth of Pennsylvania provided,
however, that if for any reason the Bank can not avail itself of the courts of
the Commonwealth of Pennsylvania (other than due to Bank's failure to qualify to
do business in Pennsylvania), the Borrower and Bank each submit to the
jurisdiction of the State and Federal Courts in Santa Clara County, California.

BORROWER AND BANK EACH WAIVE THEIR RIGHT TO A JURY TRIAL OF ANY CLAIM OR CAUSE
OF ACTION ARISING OUT OF ANY OF THE LOAN DOCUMENTS OR ANY CONTEMPLATED
TRANSACTION, INCLUDING CONTRACT, TORT, BREACH OF DUTY AND ALL OTHER CLAIMS. THIS
WAIVER IS A MATERIAL INDUCEMENT FOR BOTH PARTIES TO ENTER INTO THIS AGREEMENT.
EACH PARTY HAS REVIEWED THIS WAIVER WITH ITS COUNSEL.

records each Advance made by Bank under this Note and the amount of each payment
or prepayment of principal of each such Advance received by Bank; it being
understood, however, that failure to make any such endorsement (or any error in
notation) shall not affect the obligations of Borrower with respect to Advances
made hereunder, and payments of principal by Borrower shall be credited to
Borrower notwithstanding the failure to make a notation (or any errors in
notation) thereof on such books and records.

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

          (a) The failure of Borrower to pay to Bank within 3 days of the date
due any and all amounts payable by Borrower to Bank under the terms of this
Note; or

          (b) The occurrence and continuance of an Event of Default (as defined
therein) under the terms and conditions of any of the other Loan Documents.

     Upon the occurrence and during the continuance of an Event of Default, at
the option of Bank, all amounts payable by Borrower to Bank under the terms of
this Note shall immediately become due and payable by Borrower to Bank without
notice to Borrower or any other person, and Bank shall have all of the rights,
powers, and remedies available under the terms of this Note, any of the other
Loan Documents and all applicable laws. Borrower and all endorsers, guarantors,
and other parties who may now or in the future be primarily or secondarily
liable for the payment of the indebtedness evidenced by this Note hereby
severally waive presentment, protest and demand, notice of protest, notice of
demand and of dishonor and non-payment of this Note and expressly agree that
this Note or any payment hereunder may be extended from time to time without in
any way affecting the liability of Borrower, guarantors and endorsers.

     Borrower promises to pay all costs and expense of collection of this Note
and to pay all reasonable attorneys' fees incurred in such collection, whether
or not there is a suit or action, or in any suit or action to collect this Note
or in any appeal thereof. No delay by Bank in exercising any power or right
hereunder shall operate as a waiver of any power or right. Time is of the
essence as to all obligations hereunder.

     This Note is issued pursuant to the Loan Agreement, which shall govern the
rights and obligations of Borrower with respect to all obligations hereunder.

     Borrower acknowledges and agrees that this Note shall be governed by the
laws of the Commonwealth of Pennsylvania, excluding conflicts of laws
