Credit and Collection Policies and Practices

UNITED STATIONERS INC.

Credit Approval Policy

Exhibit B - 1

Attachment A

United Stationers, Inc.

Credit Approval Policy

Policy Statement

It is the Company’s objective to maximize profitable sales. As such, the Client Financial Services Department seeks to support sales efforts while at the same time not exposing the Company to undue credit risk. Credit solutions will be sought out to protect the Company against bad debt losses while enabling sales growth. Generally speaking, credit decision makers will seek to achieve an appropriate balance of risk and reward.

This policy establishes the following:

Credit Line Considerations

It is the policy of the Company to manage the credit exposure to a customer across all business units. The credit approval authority responsible for the customer relationship will assign a consolidated credit line and the amount to be allocated to each individual accounts receivable platform. In addition, the credit line must include exposure (if any) as the result of any unamortized upfront payments made to a customer which are subject to clawback (see description of prepaid assets in the “Accounts Receivable Deferral Policy CR-02).

It is the Company’s policy to make informed credit decisions utilizing the best information available. This includes but is not limited to the following:

In assigning a credit line, the credit approval authority (see below) may require additional collateral in order to be able to protect the Company while providing the amount of credit extension required by the customer. Examples of collateral that may be required include:

Credit lines over $25K must be reviewed annually or more often if deemed necessary due to changing requirements or circumstances.

Exhibit B - 2

Credit Approval Authorities:

Credit lines are subject to the following approval levels:

In addition, all credit lines for buying groups with a central billing program irrespective of dollar amount must be approved by the Vice President and Treasurer. A central billing program is one where all invoices for purchases are the legal responsibility of the buying group and not the member or are paid by the member to the Company through the buying group as an intermediary.

At any time, the credit decision made by an authorized individual may be superseded by an individual with higher credit authority.

If the customer has ratings from both Moody’s Investor Services and Standard and Poor’s, both ratings must be investment grade in order to be considered as such for purposes of the above matrix.

Portfolio Reviews:

Periodically, but no less than twice per year, the Credit Department will conduct detailed portfolio reviews for each Sales Channel. Invited participants include, but are not limited to the following:

Topics to be discussed at each portfolio review include but are not limited to the following:

Interpretation: All questions regarding his policy or its interpretation should be referred the Treasurer.

Exhibit B - 3

Attachment B

Procedure:

Initial credit extension

Credit Associate receives completed and signed credit application and valid resale certificate. Customer financial data (e.g. D&B report, credit references, and financial statements) is obtained and analyzed. Credit Approval authority will determine whether additional security (personal guarantee, UCC-1, or letter of credit) may need to be obtained in order to extent credit. If risk is deemed acceptable, credit limit is reviewed and approved by appropriate level of management.

Annual credit line review

Customers with credit limits of $25k or greater are reviewed at least annually, or as deemed necessary. Credit Approval Authority obtains and analyzes updated customer financial data (e.g. D&B report, credit references, and financial statements), sales and payment history. Associate reviews any additional security. Credit Approval Authority determines if current credit line is adequate or if a change is required. If change is required, limit is reviewed and approved by appropriate level of management.

Credit limits are determined to ensure that business can be transacted normally without the customer exceeding their credit limit. Transactions that result in a breach of the limit will result in a review of order requests by credit personnel.

The Credit Department reviews past due accounts daily and is responsible for contacting customers for payment. Collection activity is prioritized by age and dollar value. Customers may be contacted via phone, email, printed mail and or fax. Additionally, the Company contracts with third party agencies to assist in the collection of past due balances. Any portion of the customer balance that is deemed uncollectable is written off to bad-debt in accordance with the Bad Debt Policy.

Exhibit B - 4

UNITED STATIONERS INC.

Accounts Receivable Deferral and Customer Advance Policy

Policy Statement:

There are various ways in which a customer may request and be granted an extended due date for purchases. In addition, there are various ways in which monies may be provided to a customer in advance of purchases. Each form of deferral of accounts receivable or customer advance increases the amount of credit exposure to the customer and increases the investment in capital required to support the overall customer relationship. All such credit extensions must be within a credit line approved pursuant to the Credit Approval Policy for U.S. entities, Policy No. CR-01.

Non-Standard Payment Terms

Approval to offer a customer payment non-standard payment terms is required in situations where the due date for all invoices for a given customer will be beyond the standard payment terms for that business unit. The standard payment terms for each business unit (excluding MBS Dev) are listed in Attachment A to this policy. MBS Dev standard payment terms are shown in Attachment B.

Offering non-standard payment terms is strongly discouraged. Due dates beyond a business unit’s standard payment terms increases the credit risk associated with a customer relationship and increases the invested capital required to support the relationship. Invested capital requires a net return above the Company’s cost of capital in order to create shareholder value.

Please note that each business unit/sales channel has the authority to set its own approval requirements for offering a customer a discount for paying earlier (not later) than standard payment terms.

Extra Time

Extra Time refers to the extension of the due date of a single order beyond Standard Payment Terms. Generally speaking, such requests are only granted in the following circumstances:

Promotional Dating Programs:

A promotional dating program refers to a business unit wide program offered to all or a significant subset of the customer base to drive the purchases of a certain product(s) for a limited time period.

Set Asides

The term “set-aside” refers to the deferral of the due date of a full or partial month’s billings to be repaid over time with interest.

Exhibit B - 5

All set asides must be meet the following criteria:

It is strongly suggested that set asides meet the following criteria:

Generally speaking, approval of a set-aside will require modeling by the business unit to determine the impact on the ROIC and Economic Profit associated with a customer relationship.

Prepaid Assets

There are certain forms of customer advances issued either in the form of cash payments or credits to the customer’s account and usually defined in contract agreements (sometimes referred to as a Local Partner Rebate Agreements or “LPR”). Such upfront payments include a “clawback” provision to recover the funds in the event of non-compliance with terms and results in the payment being booked as a prepaid asset and taken to expense over time. Such advances represent a form of credit exposure. If the customer becomes insolvent or the clawback provisions are invoked before the amounts advanced have been fully earned, there is risk of a bad debt loss.

Some examples of common forms of customer advances booked as prepaid assets are as follows:

Generally speaking, approval of a customer-related prepaid asset will require modeling by the business unit to determine the impact on the ROIC and Economic Profit associated with a customer relationship

Loans: The advancement of funds to be repaid over time or at a future date, usually with interest. For variety of reasons (risk, disclosure requirements, impact on the covenants in the Company’s lending agreements, etc.), loans will only be done in rare circumstances.

Exhibit B - 6

Authorizations:

The following approvals are required based upon the form of accounts receivable deferral or customer advance (does not include MBS Dev, MBS Dev approval requirements included in Attachment B):

Exhibit B - 7

ATTACHMENT A

Standard Payment Terms

Each business unit has standard payment terms applicable to all orders for customers of that business unit (unless exceptions are approved pursuant to this policy):

—Discountables 15^th prox, Non-Discountables, up to net 20^th prox. This means that payment of the customers statement is due cash in bank by the 15^th of the following month in order to earn applicable discounts , otherwise due by the 20^th)

—Net 30 from Date of Invoice (DOI)

Bad Debt Workout and Write-Off Policy

Exhibit B - 9

Attachment A

United Stationers, Inc.

Bad Debt Workout and Write-Off Policy

Policy Statement

It is the policy of the Client Financial Services Department to use all reasonable and cost effective efforts to actively pursue obligations to the Company for goods or services. Despite best efforts, certain customers will be unable to pay and bad debt losses will be incurred. Given the potential impact on the financial results of the Company, certain actions regarding accounting for the impact of distressed receivables or the workout/resolution of such receivables requires prior authorization. Such actions include but are not limited to the following:

Specific Bad Debt Reserves

Periodically, a specific bad debt reserve will be established against a customer account where in the judgment of the Senior Credit Manager, there is the probability that all or portion of a receivable will be uncollectable due to the inability of the customer to pay for such receivable(s). Please refer to policy CR-4 for bad debt reserve policy and procedures.

Sending an Account to Third-Party Collection

The Director, Client Financial Services will maintain a list of approved collection agencies or collection counsel to whom an account may be referred for collection.

The sending of an account to collection signals the end of an ongoing business relationship with a customer. An account will not be sent to collection until all reasonable efforts to collect the receivable internally have been fully exhausted. No ongoing shipments to a customer may occur once an account has been sent to collection unless prior balances owed have been paid in full.

The sending of an account to third-party collection requires the following approvals:

Settlement or Write-Off of Distressed Account

Settlement of a distressed account refers to agreement by an authorized representative of the Company to accept less than the amount owed as payment in full for receivables owed. Write-off refers to the actual write-off of a receivable on the Company’s books and records.

The following approvals are required for the settlement or write-off of a distressed receivable:

Exhibit B - 10

Attachment B

Procedure:

Collection associates monitor customer account agings daily. Accounts with past due receivables are contacted frequently for payment. Contact can be made via phone, email, printed mail and/or fax.

If payment has not been made within a reasonable period of time and communication has deteriorated, the account is placed on “no sales allowed” by the credit associate assigned to the account. This is communicated to the customer and sales team. The account ownership is then transferred to the Sr. Debt Recovery Analyst for evaluation. The Recovery Analyst will evaluate the account and determine next steps based on known facts relative to non-payment (e.g. bankruptcy, asset sale of business, etc.) and whether the Company holds any type of security. If warranted, the Recovery Analyst will attempt to collect the monies owed either by payment in full or regular partial payments. If a 3^rd party agency or attorney is recommended, Recovery Analyst will forward or will review and gain approval as outlined in Attachment A of the policy.

Every attempt is made to collect the monies owed the Company. Any recoveries collected are applied toward the balance owed. If a settlement is negotiated, it must be reviewed and approved prior to acceptance, in accordance with Attachment A.

The account is recommended for bad-debt write off if no settlement can be reached and recovery is unlikely when:

Upon recommendation for write-off, the credit associate prepares the write-off form indicating the account information, and write-off amount. If the amount is greater than $50,000, the associate also writes a brief summary of the account history and the events leading up to the write-off. The historical summary may be written at time of referral to Recovery Analyst or at time of formal write-off.

All write-offs are appropriately reviewed and approved.
