THIS CREDIT AGREEMENT (the "Agreement") dated as of June 30, 2000 (the "Effective Date") is between Wells Fargo Bank Minnesota, National Association (the "Bank") and Datalink Corporation (the "Borrower").

BACKGROUND

    The Borrower has asked the Bank to provide it with a $10,000,000.00 line of credit to be used for financing potential acquisitions. The Borrower has also asked the Bank to provide it with a $5,000,000.00 line of credit for financing its working capital needs. The Bank is agreeable to meeting the Borrower's request, provided that the Borrower agrees to the terms and conditions of this Agreement.

    For purposes of this Agreement, Revolving Note A and Revolving Note B shall collectively be referred to as the "Notes." The Notes and this Agreement, and any modifications, amendments or replacements thereto shall be referred to collectively as the "Documents."

    In consideration of the above premises, the Bank and the Borrower agree as follows:

1.  LINE OF CREDIT A

1.1 Line of Credit A Amount. During the Line A Availability Period defined below, the Bank agrees to provide a revolving line of credit ("Line A") to the Borrower. Outstanding amounts under Line A shall not, at any one time, exceed TEN MILLION AND 00/100 DOLLARS ($10,000,000.00).

1.2 Line A Availability Period. The "Line A Availability Period" shall mean the period of time from the Effective Date or the date on which all conditions precedent described in this Agreement have been met, whichever is later, to the Line A Expiration Date of June 30, 2001.

1.3 Revolving Note A. The Borrower's obligation to repay advances under Line A shall be evidenced by a single promissory note ("Revolving Note A") dated as of the Effective Date, and in form and content acceptable to the Bank. Reference is made to Revolving Note A for interest rate and repayment terms.

2.  LINE OF CREDIT B

The Borrower's obligation to repay advances under Line B shall be evidenced by a single promissory note ("Revolving Note B") dated as of the Effective Date, and in form and content acceptable to the Bank.

2.4 Standby Letters of Credit

(a)  Issuance and Expiration.  During the Line B Availability Period, the Bank agrees to issue standby letters of credit ("Standby L/Cs") for the account of the Borrower, provided that the Borrower is in compliance with the terms of this Agreement. Each Standby L/C must expire at the earlier of the Line B Expiration Date or 180 days after issuance, or at such time as the Bank and the Borrower may agree to at the time of issuance. Prior to the issuance of a Standby L/C, the Borrower will execute the Bank's

standard Application and Agreement for Irrevocable Standby Letter of Credit (the "Standby L/C Agreement") and such other documents as the Bank deems necessary.

(b)  Fees.  The Borrower shall pay a standby letter of credit fee of 1.50% per annum on the face amount of each Standby L/C, subject to a minimum fee of $300, and calculated on the basis of actual days elapsed in a 360-day year. This fee shall be paid quarterly in advance and is in addition to all other fees or expenses provided for in the L/C Application.

(c)  Reduction of Line Availability.  Availability under Line B shall be reduced dollar for dollar by the face amount of all outstanding Standby L/Cs, plus any unreimbursed draws. Without limiting any rights and remedies available to the Bank under any Standby L/C Agreement, any draw under a Standby L/C may, at the Bank's option, be repaid through an automatic advance under Line B, which shall be repayable according to the terms of this Agreement.

(d)  Cash Collateralization of Outstanding Standby L/Cs.  Should a default occur under this Agreement, the Bank may require the Borrower to deposit with it in a non-interest bearing account, immediately available funds equal to the face amount of outstanding Standby L/Cs. The Borrower hereby grants the Bank a security interest in these funds as security for all of the Borrower's obligations to the Bank.

2.5 Documentary Letters of Credit

(a)  Issuance and Expiration.  During the Line B Availability Period, the Bank agrees to issue documentary letters of credit ("Documentary L/Cs") for the account of the Borrower, provided that the Borrower is in compliance with the terms of this Agreement. Each Documentary L/C must expire prior to the Line B Expiration Date or at such time as the Bank and the Borrower agree to at the time of issuance, and must require drafts payable at sight. Prior to the issuance of a Documentary L/C, the Borrower will execute the Bank's standard Application and Agreement for Irrevocable Documentary Letters of Credit (the "Documentary L/C Agreement") and such other documents as the Bank deems necessary.

(b)  Fees and Expenses.  Fees and expenses related to each Documentary L/C will be agreed upon at issuance.

(c)  Reduction of Line Availability.  Availability under Line B shall be reduced dollar for dollar by the face amount of all outstanding Documentary L/Cs, plus any unreimbursed draws. Without limiting any rights and remedies available to the Bank under the Documentary L/C Agreement and related documents, any draw under a Documentary L/C may, at the Bank's option, be repaid through an automatic advance under Line B, which shall be repayable according to the terms of this Agreement.

(d)  Cash Collateralization of Outstanding Documentary L/Cs.  Should a default occur under this Agreement the Bank may require the Borrower to deposit with it in a non-interest bearing account immediately available funds equal to the face amount of outstanding Documentary L/Cs. The Borrower hereby grants the Bank a security interest in these funds as security for all of the Borrower's obligations to the Bank.

2.6 Line B Commitment Fee. During the Line B Availability Period, the Borrower shall pay the Bank a commitment fee of 0.15% per annum on the average daily unused amount of Line B. This fee shall be calculated on the basis of actual days elapsed in a 360 day year and shall be paid quarterly in arrears.

3.  FEES AND EXPENSES

3.1 Documentation Expense. The Borrower agrees to reimburse the Bank for its reasonable expenses relating to the preparation of the Documents and any possible future amendments to the Documents, which reimbursement may include, but shall not be limited to, reimbursement of reasonable attorneys' fees, including the allocated costs of the Bank's in-house counsel. Despite such reimbursement the Borrower acknowledges that the Bank's counsel is engaged solely to represent the Bank and does not represent the Borrower.

3.2 Collection Expense. In the event the Borrower fails to comply with any covenant or condition of this Agreement or the Documents, or fails to pay the Bank any amounts due under this Agreement or under the Documents, the Borrower shall pay all costs of workout and collection, including reasonable attorneys' fees and legal expenses incurred by the Bank.

4.  ADVANCES AND PAYMENTS

4.1 Requests for Advances. Any line advance requested under the terms of this Agreement shall be requested by telephone or in a writing delivered to the Bank (or transmitted via facsimile) by any person reasonably believed by the Bank to be authorized by the Borrower to do so. The Bank will not consider any such request following an event which is, or with notice or the lapse of time would be, an event of default under this Agreement. Proceeds shall be deposited into the Borrower's account at the Bank or disbursed in such other manner as the parties may agree.

4.2 Interest Rate Options For Revolving Notes A and B. Revolving Notes A and B permit the Borrower to fix an interest rate for a time period and principal amount agreeable to the Bank and the Borrower, based on (1) the Base Rate (as defined in each note), floating, minus 1.0% (the "Base Rate Option"), which shall apply at all times whenever the rate has not otherwise been fixed by the agreement of the Bank and the Borrower, or (2) an interest rate or rates described in each note that is derived from and available to the Bank on international money markets for a similar time period and principal amount, which rates are more fully described in each note, plus a margin that, with respect to Revolving Note A, will vary based upon the Borrower's financial performance as provided in Section 4.3 of this Agreement, and, with respect to Revolving Note B, of 1.10% (the "LIBOR Interest Rate Option").

    To elect the LIBOR Interest Rate Option, the Borrower must request a quote from the Bank two days prior to funding. This request must designate an amount (the "LIBOR Interest Rate Portion") and a period (the "LIBOR Interest Rate Period"). The LIBOR Interest Rate Portion must be at least $100,000 and the LIBOR Interest Rate Period will be for 30, 60 or 120 days, or any other period to which the parties may agree. The Bank shall not be obligated to provide a LIBOR Interest Rate quote if it determines that no deposits with an amount and maturity equal to those for which a quotation has been requested are available to it in the London Interbank Market. The Borrower must orally accept a quote when received or it will be deemed rejected. If accepted, the LIBOR Interest Rate Option will remain in effect for the LIBOR Interest Rate Period specified in the quote. At the end of each LIBOR Interest Rate Period the principal amount subject to the LIBOR Interest Rate Option shall bear interest at the Base Rate Option.

4.3 Performance Based Rate Pricing For Line A. Following its review of the Borrower's interim financial statements and quarterly Compliance Certificate, the Bank shall adjust the LIBOR Interest Rate Option margin applicable to Revolving Note A to a margin that is based on the following performance criteria:

(a) Effective the first day of the calendar quarter in which the Borrower's Funded Debt to EBITDA Ratio, as defined in Section 7.2(d), is determined by the Bank to be less than 0.55 to 1.0, the margin shall be 1.10%.

(b) Effective the first day of the calendar quarter in which the Borrower's Funded Debt to EBITDA Ratio, as defined in Section 7.2(d), is determined by the Bank to be at least 0.55 to 1.0 but no more than 1.10 to 1.0, the margin shall be 1.30%.

(c) Effective the first day of the calendar quarter in which the Borrower's Funded Debt to EBITDA Ratio, as defined in Section 7.2(d), is determined by the Bank to be more than 1.10 to 1.0, the margin shall be 1.50%, unless the default rate of interest set forth in Section 4.5 of this Agreement is applicable.

4.4 Effective Date of Performance Based Pricing Changes. Any margin change described above shall become effective on the first day of the calendar quarter following the Bank's receipt of the Borrower's interim financial statements and Compliance Certificate as provided in Sections 7.1(b) and

7.1(c) of this Agreement. Following any event of default defined described in Section 8 of this Agreement, and regardless of whether or not the Revolving Note has been accelerated, Revolving Note A shall commence accruing interest at the rate described in Section 4.3(c) herein.

4.5 Default Rate of Interest. Following the occurrence of any event of default as defined in Section 8 of the Agreement, or following the maturity of each of Line A and Line B and the acceleration of Revolving Note A and Revolving Note B, the interest rate applicable to Revolving Note A and Revolving Note B shall be increased to annual rate equal to the Base Rate plus 2.0%, floating. This rate of interest shall commence as of the date that the Bank in its sole discretion determines that the last event constituting the event of default takes place, which period shall include any applicable grace period, if any, and shall continue through the last day of the fiscal quarter in which the event of default has been cured. The rate shall also apply in the event that Line A and Line B have matured and that Revolving Note A and Revolving Note B have been accelerated.

The Bank's assessment or acceptance of interest paid at an increased rate shall not constitute a waiver of any default under the terms of the Agreement and Revolving Note A and Revolving Note B, or a waiver of the Bank's right to terminate Line A and Line B and accelerate or demand payment of Revolving Note A or Revolving Note B.

4.6 Payments. All principal, interest and fees due under the Documents shall be paid by the direct debit of available funds deposited in the Borrower's account with the Bank. The Bank shall debit the account on the dates the payments become due. If a due date does not fall on a day on which the Bank is open for substantially all of its business (a "Banking Day", except as otherwise provided), the Bank shall debit the account on the next Banking Day, and interest shall continue to accrue during the extended period. If there are insufficient funds in the account on the day the Bank enters any debit authorized by this Agreement, the debit will be reversed and the payment shall be due immediately without necessity of demand by direct remittance of immediately available funds. For amounts bearing interest at the LIBOR Rate (if any), a Banking Day is a day on which the Bank is open for business and on which dealings in U.S. dollar deposits are carried on in the London Interbank Market.

5.  CONDITIONS PRECEDENT

    The Borrower must deliver to the Bank the documents described in Exhibit B, properly executed and in form and content acceptable to the Bank, prior to the Bank's initial advance or disbursement under this Agreement.

6.  REPRESENTATIONS AND WARRANTIES

    To induce the Bank to enter into this Agreement, the Borrower, to the best of its knowledge and upon due inquiry, makes the representations and warranties contained in Exhibit C. Each request for an advance or a disbursement under this Agreement following the Effective Date constitutes a reaffirmation of these representations and warranties.

7.  COVENANTS

    Base Rate Option.  Unless the Borrower chooses the LIBOR Interest Rate Option as defined below, the principal balance outstanding under this Revolving Note A shall bear interest at an annual rate equal to the Base Rate, minus 1.0%, floating (the "Base Rate Option"). Base Rate means the rate of interest established by the Bank from time to time as its "base" or "prime" rate of interest at its principal office in Minneapolis, Minnesota.

    LIBOR Interest Rate Option.  Subject to the terms and conditions of the Agreement the Borrower may elect that all or portions of the principal balance of this Revolving Note A bear interest at the LIBOR Interest Rate plus the margin described in Section 4.3 of the Agreement (the "LIBOR Interest Rate Option"). Specific reference is made to the Interest Rate Options section of the Agreement for terms governing the designation of interest periods and rate portions. The initial margin applicable to borrowings as of the Effective date shall be 1.10%.

    The LIBOR Interest Rate shall be computed in accordance with the following formula.

LIBOR Interest Rate	=	London Interbank Offered Rate 1.00 – Reserve Requirement
Where,

    (1) "London Interbank Offered Rate" means the Bank's cost of funds as determined by the Bank's Treasury Division, based upon the average rate at which U.S. Dollar deposits with a term equal to the applicable LIBOR Interest Rate Period and in an amount equal to the LIBOR Interest Rate Portion are available to the Bank at the time of determination on the London Interbank Market.

    (2) "Reserve Requirement" means the Federal Reserve System requirement (expressed as a percentage) applicable to the dollar deposits used in calculating the LIBOR Interest Rate above.

    DEFAULT RATE OF INTEREST.  Following the occurrence of any event of default as defined in Section 8 of the Agreement, the interest rate applicable to this Revolving Note A shall be increased to annual rate equal to the Base Rate plus 2.0%, floating. This default rate of interest shall commence as of the date that the Bank in its sole discretion determines that the last event constituting the event of default takes place, which period shall include any applicable grace period, if any, and shall continue through the last day of the fiscal quarter in which the event of default has been cured.

The Bank's assessment or acceptance of interest paid at an increased rate shall not constitute a waiver of any default under the terms of the Agreement and this Revolving Note A, or a waiver of the Bank's right to accelerate or demand payment of this Revolving Note A.

REPAYMENT TERMS

    Interest.  Interest accruing under the Base Rate Option shall be payable on the first day of each month, beginning July 1, 2000. Interest accruing under the LIBOR Interest Rate Option shall be

payable, as applicable, at the end of each LIBOR Interest Rate Period or the first day of each month, whichever is earlier.

    Principal.  Principal, and any unpaid interest, shall be due on the Line Expiration Date set forth in Section 1.2 of the Agreement.

    PREPAYMENT AND PREPAYMENT FEE.  The Borrower may prepay principal accruing interest under the Base Rate Option at any time without penalty. Each prepayment of principal accruing interest at an optional interest rate, whether voluntary or by reason of acceleration, shall be accompanied by a prepayment fee equal to the amount of interest that would have accrued on the amount of principal prepaid from the date of prepayment or its maturity or repricing date, at an annual rate equal to (1) the optional rate then in effect under this Revolving Note A on the principal being prepaid, less (2) the yield (including interest and discount) on a United States Treasury Security of comparable term that could be purchased on the date of prepayment with a maturity on (or about) the maturity or repricing date, discounted to its present value using the yield on the replacement security as a discount factor, discounted monthly; provided, however, that no prepayment fee shall be due (and no credit or rebate required) if the yield described in clause (2) exceeds the rate described in clause (1).

    Each prepayment shall be applied in inverse order of maturity or as the Bank in its sole discretion may deem appropriate. Such prepayment shall not excuse the Borrower from making subsequent payments in the order agreed to above until the indebtedness is paid in full.

    ADDITIONAL TERMS AND CONDITIONS.  This Revolving Note A is issued pursuant to a Credit Agreement of even date between the Bank and the Borrower (the "Agreement"). The Agreement, and any amendments or substitutions, contains additional terms and conditions, including default and acceleration provisions, which are incorporated into this Revolving Note A by reference. Capitalized terms not expressly defined herein shall have the meanings given them in the Agreement. The Borrower agrees to pay all costs of collection, including reasonable attorneys' fees and legal expenses incurred by the Bank if this Revolving Note A is not paid as provided above. This Revolving Note A shall be governed by the substantive laws of the State of Minnesota.

    WAIVER OF PRESENTMENT AND NOTICE OF DISHONOR.  Borrower and any other person who signs, guarantees or endorses this Revolving Note A, to the extent allowed by law, hereby waives presentment, demand for payment, notice of dishonor, protest, and any notice relating to the acceleration of the maturity of this Revolving Note A.
