                                                                 August 17, 2000

Kohlberg & Company, L.L.C.

Mt. Kisco, New York 10549
Attention: Mr. Chris Lacovara

Gentlemen:

     I'm pleased to confirm the agreement in principle of The Prudential
Insurance Company of America, itself, or through one or more of its subsidiaries
or managed accounts ("Prudential"), subject to the following conditions, to
purchase from KBII Acquisition Company, Inc. a newly formed corporation (the
"Company") $19,000,000 principal amount of 13%* Subordinated Fixed Rate Term
Notes due 2008 (the "Notes"), with detachable warrants for the purchase of
common equity representing 14.5% of the fully diluted common equity of KBII
Holdings, Inc. a newly formed corporation ("Holdings") at a nominal purchase and
exercise price. Holdings shall own 100% of the outstanding capital stock of the
Company. The Notes and the warrants are collectively referred to as the
"Securities". Prudential's agreement in principle will expire October 15, 2000,
unless extended in writing by Prudential. The purchase price of the Notes will
be 100% of the principal amount thereof. Certain terms with respect to the
Securities would be as provided in the summary of terms and conditions attached.

     Prudential's purchase of the Securities would be subject to these
conditions:

     (a)   Prudential, the Company, Holdings' equity holders and the Company's
senior lenders have agreed on the terms, conditions, covenants and other
provisions (including subordination provisions) satisfactory to Prudential with
respect to the Securities,

     (b)   Holdings has received $28.4 million in cash consideration for its
common stock, not less than $24.5 million of which shall come from Kohlberg &
Company (or affiliates thereof),

     (c)   The Company has entered into a $47.5 million senior credit facility
with lenders and on terms satisfactory to Prudential, $37.5 million of which
shall be simultaneously funded with the Notes,

- -----------------------------------------------------------
*This rate is subject to change until locked by the Company
 and may increase based upon changes in the U.S. Treasury
 market and/or changes in Prudential's credit spreads.

     (d)   Prudential is satisfied that no material adverse change in the
condition (financial or otherwise) or prospects of BI Incorporated ("BI") has
occurred since June 30, 1999,

     (e)   the information provided to the date of this letter with respect to
BI, the Company and Holdings is complete and accurate in all material respects,

     (f)   the Company simultaneously acquires on a non-hostile basis not less
than 90% of the outstanding common stock of BI on terms and conditions
satisfactory to Prudential,

     (g) Prudential's Law Department is satisfied with the documentation,
proceedings, legal opinions and other matters relating to the proposed
financing, and

     (h)   a $285,000 processing fee has been paid to Prudential, $115,000 upon
the acceptance by the Company of this letter, and the balance at closing.

     The processing fee shall be non-refundable. In addition, following rate
lock with respect to the Notes, the Company may have to pay one or both of the
fees described below.

     The first fee, the Delayed Delivery Fee, would be due if the financing is
not canceled or closed by the 42nd day following rate lock. It represents the
loss in yield to Prudential from receiving the coupon on the Notes later than
expected and would be calculated each time the proposed closing date is
extended. This fee must be paid on the date the transaction closes or is
canceled.

     To calculate the Delayed Delivery Fee, Prudential would:

     Step 1. determine the semi-annual yield of the Notes;

     Step 2. determine the yield of a short-term investment of its choice over
             the expected period of delay;

     Step 3. subtract the short-term yield (Step 2) from the Note yield (Step
             1);

     Step 4. multiply that amount (Step 3) by the number of days from the 42nd
             day after the coupon was fixed to the date this financing closes or
             is canceled;

     Step 5. divide that amount (Step 4) by 360; and

     Step 6. multiply that amount (Step 5) by the dollar amount of the Notes on
             which the coupon was fixed.

     The second fee, the Cancellation Fee, could be due if the financing is
canceled for any reason after the Company has locked a rate on the Notes. It
represents the effect of an increase after the coupon was fixed in the purchase
price of a U.S. Treasury Note comparable in duration to the Notes. This fee
must be paid on the date the transaction is canceled.

     To calculate the Cancellation Fee, Prudential would:

     Step 1. determine the bid price of a U.S. Treasury Note with a duration
             closest to that of the Notes, on the date the coupon was fixed;

     Step 2. determine the ask price of the same Treasury Note on the date the
             financing is canceled;

     Step 3. subtract the bid price (Step 1) from the ask price (Step 2). If the
             difference is a negative number, no Cancellation Fee would be due.
             If the difference is a positive number, then Prudential would -

     Step 4. divide the price increase (Step 3) by the bid price (Step 1); and

     Step 5. multiply that amount (Step 4) by the dollar amount of the Notes on
             which the coupon was fixed.

To determine the price of the Treasury Notes, Prudential will use the prices
reported by Bridge\Telerate Service or any other publicly available source of
similar market data. We will also round the price to two decimal places and base
each price on a Treasury Note with a par value of $100.

     In calculating both the Delayed Delivery Fee and Cancellation Fee, the
transaction will be considered "canceled" on October 15, 2000 (or such later day
we may agree to in writing) or on any prior day on which the Company has told
Prudential that the Company no longer wants to pursue the proposed financing.

     We intend to hire the law firm of Cooley Godward to represent us in
connection with the proposed transaction and may hire other consultants to
advise us with respect to discrete issues. We understand that Kohlberg &
Company, L.L.C. will pay the fees, charges and disbursements of Cooley Godward
and any such consultants if the proposed transaction fails to close for any
reason and that the Company will make such payments in the event the proposed
transaction closes.

* Rate subject to change until locked
** In year 3 only, if the pro forma cash on cash return to Prudential on its
                          ---------
Notes and warrants would be: (i) greater than 2.00x, the Make Whole Amount will
be reduced to the extent necessary (but in no event beyond zero) to result in a
cash on cash return of 2.00x (or such greater return as results following
elimination of the Make Whole Amount); and (ii) at least 1.85x but less than
2.00x, then in lieu of the Make Whole Amount, the amount shall be 108%, but in
no event will this reduction result in a cash on cash return of less than 1.85x.




                        If there is not a concurrent Liquidity Event, the Notes
                        will be redeemable at the option of the Company, in
                        whole or in part, at any time, plus accrued and unpaid
                        interest thereon, at the following terms (percentages
                        are percentage of principal amount):

                        Years 1-3:      100% + Make Whole Amount
                        Year 4:         110.00%
                        Year 5:         107.00%
                        Year 6:         105.00%
                        Year 7:         103.00%

                        Notwithstanding the foregoing, no optional prepayment
                        shall be permitted without the consent of Prudential if
                        (i) there is no concurrent Liquidity Event and (ii) such
                        prepayment would result in a right to put the Warrants
                        and, furthermore, if such put right were exercised, the
                        Company would not be permitted to pay 100% of the put
                        price in cash for any reason.

Make Whole Amount
 Definition:            The "Make Whole Amount" shall be equal to the excess of
                        (x) the present value of the expected future principal
                        and interest payments on the Notes (including all PIK
                        amounts) discounted at a rate equal to the Treasury Note
                        yield corresponding closest to the weighted remaining
                        average life on the Notes calculated at the time of the
                        prepayment plus 100 basis points (or, in the case of a
                        year 3 Liquidity Event, 250 basis points) over (y) the
                        outstanding accreted amount. The Make Whole Amount shall
                        in no event be less than 0.

Liquidity Event
 Definition:            "Liquidity Event" shall mean (i) the sale in a single
                        transaction of substantially all of Holdings equity
                        securities (include all of the warrants and shares
                                            ------
                        purchased upon exercise), (ii) a qualified initial
                        public offering of Holdings common stock by a nationally
                        recognized underwriter of more than $35 million in gross
                        proceeds or (iii) the sale of all or substantially all
                        of the Company's assets and the concurrent distribution
                        to the holders of the warrants and shares purchased upon
                        exercise thereof of their pro rata share of the net
                        sales proceeds.

Security:               None.


Ranking:                The Notes will rank junior in right of payment to the
                        Company's senior indebtedness incurred under the
                        proposed senior credit facilities and up to $7.5 million
                        other senior indebtedness. The amount of senior
                        indebtedness that the Notes will be subordinated to will
                        at no time be greater than $55 million. The Notes will
                        include other subordination terms with respect to the
                        Company's senior lenders typical for transactions of
                        this type satisfactory to Prudential. All other future
                        subordinated debt will rank junior to the Notes pursuant
                        to terms satisfactory to Prudential.

Change of Control:      In the event of a Change of Control, the Company will,
                        at the option of the holders thereof, (i) purchase all
                        of the outstanding Notes at the Optional Redemption
                        price, and (ii) other than in a circumstance where Take
                        Along Rights or Come Along Rights are concurrently
                        exercised (to the extent so exercised in the case of
                        Come Along Rights), purchase the warrants and any shares
                        purchased upon exercise thereof at the fair market value
                        thereof.

                        "Change of Control" will be deemed to have occurred at
                        such time as Kohlberg & Company ("Kohlberg") ceases to
                        control a majority of the Board of Directors of
                        Holdings.

Financial Covenants:    To be determined and expected to be at levels 10% to 15%
                        behind the Senior Secured Credit Facilities. The
                        Financial Covenants will include (but not be limited

                        (iii) Minimum Fixed Charge Coverage Ratio.

                        not limited to):

                        (i)   Limitations on indebtedness, including

Affirmative Covenants:  As are customary, including consummation of the "squeeze
                        out" merger with BI by a date certain.

Representations and
 Warranties:            Customary and acceptable to Prudential.

Conditions Precedent:   As are customary, including conditions relevant to the

                        special counsel and other costs incurred in connection
                        with the documentation and closing of the Notes are
                        payable by the Company if the transaction closes and by

                        obligated to be "taken along" in any sale to a non-
                        affiliate of all of the common stock (and equivalents)
                        by the other stockholders of Holdings, on the same
                        terms.

                        of the shares held by them at closing of this

                        entitled to sell their shares on a pro rata basis and on

                        amount of the Notes in a non-Liquidity Event context, or
