PROMISSORY NOTE

References in the boxes above are for Lender’s use only and do not limit the applicability of this document to any particular loan or item.

Any item above containing “***” has been omitted due to text length limitations.

PROMISE TO PAY. Allin Consulting of Pennsylvania, Inc.; Allin Corporation; Allin Corporation of California; Allin Holdings Corporation; Allin Interactive Corporation; Allin Network Products, Inc.; and Codelab Technology Group, Inc. (“Borrower”) jointly and severally promise to pay to S&T Bank (“Lender”), or order, in lawful money of the United States of America, the principal amount of Two Million & 00/100 Dollars ($2,000,000.00) or so much as may be outstanding, together with interest on the unpaid outstanding principal balance of each advance. Interest shall be calculated from the date of each advance until repayment of each advance.

PAYMENT. Borrower will pay this loan in one payment of all outstanding principal plus all accrued unpaid interest on October 30, 2008. In addition, Borrower will pay regular monthly payments of all accrued unpaid interest due as of each payment date, beginning January 30, 2008, with all subsequent interest payments to be due on the same day of each month after that. Unless otherwise agreed or required by applicable law, payments will be applied first to any accrued unpaid interest; then to principal; then to any unpaid collection costs; and then to any late charges. The annual interest rate for this Note is computed on a 365/360 basis; that is, by applying the ratio of the annual interest rate over a year of 360 days, multiplied by the outstanding principal balance, multiplied by the actual number of days the principal balance is outstanding. Borrower will pay Lender at Lender’s address shown above or at such other place as Lender may designate in writing.

VARIABLE INTEREST RATE. The interest rate on this Note is subject to change from time to time based on changes in an index which is Lender’s Prime Rate (the “Index”). This is the rate Lender charges, or would charge, on 90-day unsecured loans to the most creditworthy corporate customers. This rate may or may not be the lowest rate available from Lender at any given time. Lender will tell Borrower the current Index rate upon Borrower’s request. The interest rate change will not occur more often than each day. Borrower understands that Lender may make loans based on other rates as well. The Index currently is 7.250% per annum. The interest rate to be applied to the unpaid principal balance during this Note will be at a rate of 0.500 percentage points over the Index, resulting in an initial rate of 7.750% per annum. NOTICE: Under no circumstances will the interest rate on this Note be more than the maximum rate allowed by applicable law.

PREPAYMENT. Borrower agrees that all loan fees and other prepaid finance charges are earned fully as of the date of the loan and will not be subject to refund upon early payment (whether voluntary or as a result of default), except as otherwise required by law. Except for the foregoing, Borrower may pay without penalty all or a portion of the amount owed earlier than it is due. Early payments will not, unless agreed to by Lender in writing, relieve Borrower of Borrower’s obligation to continue to make payments of accrued unpaid interest. Rather, early payments will reduce the principal balance due. Borrower agrees not to send Lender payments marked “paid in full”, “without recourse”, or similar language. If Borrower sends such a payment, Lender may accept it without losing any of Lender’s rights under this Note, and Borrower will remain obligated to pay any further amount owed to Lender. All written communications concerning disputed amounts, including any check or other payment instrument that indicates that the payment constitutes “payment in full” of the amount owed or that is tendered with other conditions or limitations or as full satisfaction of a disputed amount must be mailed or delivered to: S&T Bank, Attention: Loan Servicing Center, PO Box 469 Indiana, PA 15701.

LATE CHARGE. If a payment is 16 days or more late, Borrower will be charged 5.000% of the regularly scheduled payment or $20.00, whichever is greater.

INTEREST AFTER DEFAULT. Upon default, including failure to pay upon final maturity, the interest rate on this Note shall be increased by adding a 3.000 percentage point margin (“Default Rate Margin”). The Default Rate Margin shall also apply to each succeeding interest rate change that would have applied had there been no default. If judgment is entered in connection with this Note, interest will continue to accrue after the date of judgment at the rate in effect at the time judgment is entered. However, in no event will the interest rate exceed the maximum interest rate limitations under applicable law.

DEFAULT. Each of the following shall constitute an event of default (“Event of Default”) under this Note:

Payment Default. Borrower fails to make any payment when due under this Note.

Other Defaults. Borrower fails to comply with or to perform any other term, obligation, covenant or condition contained in this Note or in any of the related documents or to comply with or to perform any term, obligation, covenant or condition contained in any other agreement between Lender and Borrower.

False Statements. Any warranty, representation or statement made or furnished to Lender by Borrower or on Borrower’s behalf under this Note or the related documents is false or misleading in any material respect, either now or at the time made or furnished or becomes false or misleading at any time thereafter.

Insolvency. The dissolution or termination of Borrower’s existence as a going business, the insolvency of Borrower, the appointment of a receiver for any part of Borrower’s property, any assignment for the benefit of creditors, any type of creditor workout, or the commencement of any proceeding under any bankruptcy or insolvency laws by or against Borrower.

Creditor or Forfeiture Proceedings. Commencement of foreclosure or forfeiture proceedings, whether by judicial proceeding, self-help, repossession or any other method, by any creditor of Borrower or by any governmental agency against any collateral securing the loan. This includes a garnishment of any of Borrower’s accounts, including deposit accounts, with Lender. However, this Event of Default shall not apply if there is a good faith dispute by Borrower as to the validity or reasonableness of the claim which is the basis of the creditor or forfeiture proceeding and if Borrower gives Lender written notice of the creditor or forfeiture proceeding and deposits with Lender monies or a surety bond for the creditor or forfeiture proceeding, in an amount determined by Lender, in its sole discretion, as being an adequate reserve or bond for the dispute.

Events Affecting Guarantor. Any of the preceding events occurs with respect to any guarantor, endorser, surety, or accommodation party of any of the indebtedness or any guarantor, endorser, surety, or accommodation party dies or becomes incompetent, or revokes or disputes the validity of, or liability under, any guaranty of the indebtedness evidenced by this Note. In the event of a death, Lender, at its option, may, but shall not be required to, permit the guarantor’s estate to assume unconditionally the obligations arising under the guaranty in a manner satisfactory to Lender, and, in doing so, cure any Event of Default.

Change In Ownership. Any change in ownership of twenty-five percent (25%) or more of the common stock of Borrower.

Adverse Change. A material adverse change occurs in Borrower’s financial condition, or Lender believes the prospect of payment or performance of this Note is impaired.

Insecurity. Lender in good faith believes itself insecure.

LENDER’S RIGHTS. Upon default, Lender may, after giving such notices as required by applicable law, declare the entire unpaid principal balance under this Note and all accrued unpaid interest immediately due, and then Borrower will pay that amount.

ATTORNEYS’ FEES; EXPENSES. Lender may hire or pay someone else to help collect this Note if Borrower does not pay. Borrower will pay Lender that amount. This includes, subject to any limits under applicable law, Lender’s reasonable attorneys’ fees and Lender’s legal expenses, whether or not there is a lawsuit, including reasonable attorneys’ fees, expenses for bankruptcy proceedings (including efforts to modify or vacate any automatic stay or injunction), and appeals. If not prohibited by applicable law, Borrower also will pay any court costs, in addition to all other sums provided by law.

JURY WAIVER. Lender and Borrower hereby waive the right to any jury trial in any action, proceeding, or counterclaim brought by either Lender or Borrower against the other.

GOVERNING LAW. This Note will be governed by federal law applicable to Lender and, to the extent not preempted by federal law, the laws of the Commonwealth of Pennsylvania without regard to its conflicts of law provisions. This Note has been accepted by Lender in the Commonwealth of Pennsylvania.

CHOICE OF VENUE. If there is a lawsuit, Borrower agrees upon Lender’s request to submit to the jurisdiction of the courts of Allegheny County, Commonwealth of Pennsylvania.

RIGHT OF SETOFF. To the extent permitted by applicable law, Lender reserves a right of setoff in all Borrower’s accounts with Lender (whether checking, savings, or some other account). This includes all accounts Borrower holds jointly with someone else and all accounts Borrower may open in the future. However, this does not include any IRA or Keogh accounts, or any trust accounts for which setoff would be prohibited by law. Borrower authorizes Lender, to the extent permitted by applicable law, to charge or setoff all sums owing on the indebtedness against any and all such accounts.

LINE OF CREDIT. This Note evidences a straight line of credit. Once the total amount of principal has been advanced, Borrower is not entitled to further loan advances. Advances under this Note may be requested either orally or in writing by Borrower or by an authorized person. Lender may, but need not, require that all oral requests be confirmed in writing. All communications, instructions, or directions by telephone or otherwise to Lender are to be directed to Lender’s office shown above. Borrower agrees to be liable for all sums either: (A) advanced in accordance with the instructions of an authorized person or (B) credited to any of Borrower’s accounts with Lender. The unpaid principal balance owing on this Note at any time may be evidenced by endorsements on this Note or by Lender’s internal records, including daily computer print-outs.

LETTER OF CREDIT AVAILABILITY. In addition to the terms previously set forth, availability under the Note shall be reduced by the amount of any outstanding documentary or standby Letters of Credit issued by the Lender for the Borrower’s account. Letters of Credit issued under this line of credit must be issued with an expiration date prior to the maturity date of the Note. Letters of Credit issued for the Borrower, which are presented for payment prior to the maturity date of the Note, shall be funded by an advance from the line of credit as evidenced by the Note. If not sooner paid, all Letters of Credit presented for payment and funded by an advance from the line of credit shall be due and payable upon the maturity date of the Note.

SUCCESSOR INTERESTS. The terms of this Note shall be binding upon Borrower, and upon Borrower’s heirs, personal representatives, successors and assigns, and shall inure to the benefit of Lender and its successors and assigns.

GENERAL PROVISIONS. If any part of this Note cannot be enforced, this fact will not affect the rest of the Note. Lender may delay or forgo enforcing any of its rights or remedies under this Note without losing them. Each Borrower understands and agrees that, with or without notice to Borrower, Lender may with respect to any other Borrower (a) make one or more additional secured or unsecured loans or otherwise extend additional credit; (b) alter, compromise, renew, extend, accelerate, or otherwise change one or more times the time for payment or other terms of any indebtedness, including increases and decreases of the rate of interest on the indebtedness; (c) exchange, enforce, waive, subordinate, fail or decide not to perfect, and release any security, with or without the substitution of new collateral; (d) apply such security and direct the order or manner of sale thereof, including without limitation, any non-judicial sale permitted by the terms of the controlling security agreements, as Lender in its discretion may determine; (e) release, substitute, agree not to sue, or deal with any one or more of Borrower’s sureties, endorsers, or other guarantors on any terms or in any manner Lender may choose; and (f) determine how, when and what application of payments and credits shall be made on any other indebtedness owing by such other Borrower. Borrower and any other person who signs, guarantees or endorses this Note, to the extent allowed by law, waive presentment, demand for payment, and notice of dishonor. Upon any change in the terms of this Note, and unless otherwise expressly stated in writing, no party who signs this Note, whether as maker, guarantor, accommodation maker or endorser, shall be released from liability. All such parties agree that Lender may renew or extend (repeatedly and for any length of time) this loan or release any party or guarantor or collateral; or impair, fail to realize upon or perfect Lender’s security interest in the collateral; and take any other action deemed necessary by Lender without the consent of or notice to anyone. All such parties also agree that Lender may modify this loan without the consent of or notice to anyone other than the party with whom the modification is made. The obligations under this Note are joint and several. If any portion of this Note is for any reason determined to be unenforceable, it will not affect the enforceability of any other provisions of this Note.

BORROWER HEREBY IRREVOCABLY AUTHORIZES AND EMPOWERS ANY ATTORNEY OR THE PROTHONOTARY OR CLERK OF ANY COURT IN THE COMMONWEALTH OF PENNSYLVANIA, OR ELSEWHERE, TO APPEAR AT ANY TIME FOR BORROWER AFTER A DEFAULT UNDER THIS NOTE AND WITH OR WITHOUT COMPLAINT FILED, CONFESS OR ENTER JUDGMENT AGAINST BORROWER FOR THE ENTIRE PRINCIPAL BALANCE OF THIS NOTE AND ALL ACCRUED INTEREST, LATE CHARGES AND ANY AND ALL AMOUNTS EXPENDED OR ADVANCED BY LENDER RELATING TO ANY COLLATERAL SECURING THIS NOTE, TOGETHER WITH COSTS OF SUIT, AND AN ATTORNEY’S COMMISSION OF TEN PERCENT (10%) OF THE UNPAID PRINCIPAL BALANCE AND ACCRUED INTEREST FOR COLLECTION, BUT IN ANY EVENT NOT LESS THAN FIVE HUNDRED DOLLARS ($500) ON WHICH JUDGMENT OR JUDGMENTS ONE OR MORE EXECUTIONS MAY ISSUE IMMEDIATELY; AND FOR SO DOING, THIS NOTE OR A COPY OF THIS NOTE VERIFIED BY AFFIDAVIT SHALL BE SUFFICIENT WARRANT.
