                  THIS SUBSIDIARIES GUARANTY, dated as of March 25, 2004 (as
amended, modified or supplemented from time to time, this "Guaranty"), is made
by each of the undersigned guarantors (each a "Guarantor," and together with any
other entity that becomes a guarantor hereunder pursuant to Section 26 hereof,
the "Guarantors"). Except as otherwise defined herein, capitalized terms used
herein and defined in the Credit Agreement (as defined below) shall be used
herein as therein defined.

                  WHEREAS, infoUSA Inc. (the "Borrower"), the financial
institutions from time to time party thereto in the capacity of a lender (in
such capacity, the "Lenders"), and Wells Fargo Bank, National Association, as
administrative agent (together with any successor administrative agent, the
"Administrative Agent"), have entered into a Credit Agreement, dated as of March
25, 2004 (as amended, modified, or supplemented from time to time, the "Credit
Agreement"), providing for the making of Loans to, and the issuance of Letters
of Credit for the account of, the Borrower as contemplated therein (the Lenders,
the Collateral Agent, the Issuing Lender and the Administrative Agent are herein
called the "Lender Creditors");

                  WHEREAS, the Borrower may at any time and from time to time
enter into one or more Interest Rate Protection Agreements or Other Hedging
Agreements with one or more Lenders or any affiliate thereof (each such Lender
or affiliate, even if the respective Lender subsequently ceases to be a Lender
under the Credit Agreement for any reason, together with such Lender's or
affiliate's successors and assigns, if any, collectively, the "Other Creditors,"
and together with the Lender Creditors, the "Secured Creditors");

                  WHEREAS, each Guarantor is a direct or indirect Subsidiary of
the Borrower;

                  WHEREAS, it is a condition to the making of Loans to, and the
issuance of Letters of Credit for the account of, the Borrower under the Credit
Agreement that each Guarantor shall have executed and delivered this Guaranty;
and

                  WHEREAS, each Guarantor will obtain benefits from the
incurrence of Loans to, and the issuance of Letters of Credit for the account
of, the Borrower under the Credit Agreement and the entering into by the
Borrower of Interest Rate Protection Agreements or Other Hedging Agreements and,
accordingly, desires to execute this Guaranty in order to satisfy the conditions
described in the preceding paragraph;

                  NOW, THEREFORE, in consideration of the foregoing and other
benefits accruing to each Guarantor, the receipt and sufficiency of which are
hereby acknowledged, each



                  Guarantor hereby makes the following representations and
warranties to the Secured Creditors and hereby covenants and agrees with each
Secured Creditor as follows:

                  1.       Each Guarantor, jointly and severally, irrevocably,
absolutely and unconditionally guarantees: (i) to the Lender Creditors the full
and prompt payment when due (whether at the stated maturity, by acceleration or
otherwise) of (x) the principal of, premium, if any, and interest on the Notes
issued by, and the Loans made to, the Borrower under the Credit Agreement, and
all reimbursement obligations and Unpaid Drawings with respect to Letters of
Credit issued under the Credit Agreement and (y) all other obligations
(including obligations which, but for the automatic stay under Section 362(a) of
the Bankruptcy Code, would become due), liabilities and indebtedness owing by
the Borrower to the Lender Creditors under the Credit Agreement and any other
Credit Document to which the Borrower is a party (including, without limitation,
indemnities, Fees and interest thereon), whether now existing or hereafter
incurred under, arising out of or in connection with the Credit Agreement and
any such other Credit Document and the due performance and compliance by the
Borrower with all of the terms, conditions and agreements contained in all such
Credit Documents (all such principal, premium, interest, liabilities,
indebtedness and obligations being herein collectively called the "Credit
Document Obligations"); and (ii) to each Other Creditor the full and prompt
payment when due (whether at the stated maturity, by acceleration or otherwise)
of all obligations (including obligations which, but for the automatic stay
under Section 362(a) of the Bankruptcy Code, would become due), liabilities and
indebtedness owing by the Borrower under any Interest Rate Protection Agreement
and Other Hedging Agreement, whether now in existence or hereafter arising, and
the due performance and compliance by the Borrower with all of the terms,
conditions and agreements contained in the Interest Rate Protection Agreements
and Other Hedging Agreements (all such obligations, liabilities and indebtedness
being herein collectively called the "Other Obligations," and together with the
Credit Document Obligations, the "Guaranteed Obligations"). Each Guarantor
understands, agrees and confirms that the Secured Creditors may enforce this
Guaranty up to the full amount of the Guaranteed Obligations against such
Guarantor without proceeding against any other Guarantor, the Borrower, against
any security for the Guaranteed Obligations, or under any other guaranty
covering all or a portion of the Guaranteed Obligations.

                  2.       Additionally, each Guarantor, jointly and severally,
unconditionally, absolutely and irrevocably, guarantees the payment of any and
all Guaranteed Obligations whether or not due or payable by the Borrower upon
the occurrence in respect of the Borrower of any of the events specified in
Section 11.1(e) of the Credit Agreement, and unconditionally and irrevocably,
jointly and severally, promises to pay such Guaranteed Obligations to the
Secured Creditors, or order, on demand, in legal tender of the United States.
This Guaranty shall constitute a guaranty of payment, and not of collection.

                  3.       The liability of each Guarantor hereunder is primary,
absolute and unconditional and is exclusive and independent of any security for
or other guaranty of the indebtedness of the Borrower whether executed by such
Guarantor, any other

                                      -2-


Guarantor, any other guarantor or by any other party, and the liability of each
Guarantor hereunder shall not be affected or impaired by any circumstance or
occurrence whatsoever, including, without limitation: (a) any direction as to
application of payment by the Borrower or by any other party, (b) any other
continuing or other guaranty, undertaking or maximum liability of a guarantor or
of any other party as to the Guaranteed Obligations, (c) any payment on or in
reduction of any such other guaranty or undertaking, (d) any dissolution,
termination or increase, decrease or change in personnel by the Borrower, (e)
any payment made to any Secured Creditor on the indebtedness which any Secured
Creditor repays the Borrower pursuant to court order in any bankruptcy,
reorganization, arrangement, moratorium or other debtor relief proceeding, and
each Guarantor waives any right to the deferral or modification of its
obligations hereunder by reason of any such proceeding, (f) any action or
inaction by the Secured Creditors as contemplated in Section 6 hereof or (g) any
invalidity, irregularity or unenforceability of all or any part of the
Guaranteed Obligations or of any security therefor.

                  4.       The obligations of each Guarantor hereunder are
independent of the obligations of any other Guarantor, any other guarantor or
the Borrower, and a separate action or actions may be brought and prosecuted
against each Guarantor whether or not action is brought against any other
Guarantor, any other guarantor or the Borrower and whether or not any other
Guarantor, any other guarantor or the Borrower be joined in any such action or
actions. Each Guarantor waives, to the fullest extent permitted by law, the
benefits of any statute of limitations affecting its liability hereunder or the
enforcement thereof. Any payment by the Borrower or other circumstance which
operates to toll any statute of limitations as to the Borrower shall operate to
toll the statute of limitations as to each Guarantor.

                  5.       Each Guarantor hereby waives notice of acceptance of
this Guaranty and notice of any liability to which it may apply, and waives
promptness, diligence, presentment, demand of payment, protest, notice of
dishonor or nonpayment of any such liabilities, suit or taking of other action
by the Administrative Agent or any other Secured Creditor against, and any other
notice to, any party liable thereon (including such Guarantor, any other
Guarantor, any other guarantor or the Borrower)

                  6.       Any Secured Creditor may at any time and from time to
time without the consent of, or notice to, any Guarantor, without incurring
responsibility to such Guarantor, without impairing or releasing the obligations
of such Guarantor hereunder, upon or without any terms or conditions and in
whole or in part:

                  (a)      change the manner, place or terms of payment of,
         and/or change, increase or extend the time of payment of, renew or
         alter, any of the Guaranteed Obligations (including any increase or
         decrease in the rate of interest thereon), any security therefor, or
         any liability incurred directly or indirectly in respect thereof, and
         the guaranty herein made shall apply to the Guaranteed Obligations as
         so changed, extended, renewed or altered;

                  (b)      take and hold security for the payment of the
         Guaranteed Obligations and sell, exchange, release, surrender, impair,
         realize upon or

                                      -3-


         otherwise deal with in any manner and in any order any property by
         whomsoever at any time pledged or mortgaged to secure, or howsoever
         securing, the Guaranteed Obligations or any liabilities (including any
         of those hereunder) incurred directly or indirectly in respect thereof
         or hereof, and/or any offset thereagainst;

                  (c)      exercise or refrain from exercising any rights
         against the Borrower, any other Credit Party, any Subsidiary thereof or
         otherwise act or refrain from acting;

                  (d)      release or substitute any one or more endorsers,
         Guarantors, other guarantors, the Borrower or other obligors;

                  (e)      settle or compromise any of the Guaranteed
         Obligations, any security therefor or any liability (including any of
         those hereunder) incurred directly or indirectly in respect thereof or
         hereof, and may subordinate the payment of all or any part thereof to
         the payment of any liability (whether due or not) of the Borrower to
         creditors of the Borrower other than the Secured Creditors;

                  (f)      apply any sums by whomsoever paid or howsoever
         realized to any liability or liabilities of the Borrower to the Secured
         Creditors regardless of what liabilities of the Borrower remain unpaid;

                  (g)      consent to or waive any breach of, or any act,
         omission or default under, any of the Interest Rate Protection
         Agreements or Other Hedging Agreements, the Credit Documents or any of
         the instruments or agreements referred to therein, or otherwise amend,
         modify or supplement any of the Interest Rate Protection Agreements or
         Other Hedging Agreements, the Credit Documents or any of such other
         instruments or agreements;

                  (h)      act or fail to act in any manner referred to in this
         Guaranty which may deprive such Guarantor of its right to subrogation
         against the Borrower to recover full indemnity for any payments made
         pursuant to this Guaranty; and/or

                  (i)      take any other action which would, under otherwise
         applicable principles of common law, give rise to a legal or equitable
         discharge of such Guarantor from its liabilities under this Guaranty.

                  7.       This Guaranty is a continuing one and all liabilities
to which it applies or may apply under the terms hereof shall be conclusively
presumed to have been created in reliance hereon. No failure or delay on the
part of any Secured Creditor in exercising any right, power or privilege
hereunder shall operate as a waiver thereof, nor shall any single or partial
exercise of any right, power or privilege hereunder preclude any other or
further exercise thereof or the exercise of any other right, power or privilege.
The rights and remedies herein expressly specified are cumulative and not
exclusive of any rights or remedies which any Secured Creditor would otherwise
have. No notice to or demand on any Guarantor in any case shall entitle such
Guarantor to any other further

                                      -4-


notice or demand in similar or other circumstances or constitute a waiver of the
rights of any Secured Creditor to any other or further action in any
circumstances without notice or demand. It is not necessary for any Secured
Creditor to inquire into the capacity or powers of the Borrower or the officers,
directors, partners or agents acting or purporting to act on its behalf, and any
indebtedness made or created in reliance upon the professed exercise of such
powers shall be guaranteed hereunder.

                  8.       Any indebtedness of the Borrower now or hereafter
held by any Guarantor is hereby subordinated to the indebtedness of the Borrower
to the Secured Creditors, and such indebtedness of the Borrower to any
Guarantor, if the Administrative Agent or the Collateral Agent, after the
occurrence and during the continuance of an Event of Default, so requests, shall
be collected, enforced and received by such Guarantor as trustee for the Secured
Creditors and be paid over to the Secured Creditors on account of the
indebtedness of the Borrower to the Secured Creditors, but without affecting or
impairing in any manner the liability of such Guarantor under the other
provisions of this Guaranty. Without limiting the generality of the foregoing,
each Guarantor hereby agrees with the Secured Creditors that it will not
exercise any right of subrogation which it may at any time otherwise have as a
result of this Guaranty (whether contractual, under Section 509 of the
Bankruptcy Code or otherwise) until all Guaranteed Obligations have been
irrevocably paid in full in cash.

                  9.       (a)      Each Guarantor waives any right (except as
         shall be required by applicable law and cannot be waived) to require
         the Secured Creditors to: (i) proceed against the Borrower, any other
         Guarantor, any other guarantor of the Guaranteed Obligations or any
         other party; (ii) proceed against or exhaust any security held from the
         Borrower, any other Guarantor, any other guarantor of the Guaranteed
         Obligations or any other party; or (iii) pursue any other remedy in the
         Secured Creditors' power whatsoever. Each Guarantor waives any defense
         based on or arising out of any defense of the Borrower, any other
         Guarantor, any other guarantor of the Guaranteed Obligations or any
         other party other than payment in full of the Guaranteed Obligations,
         including, without limitation, any defense based on or arising out of
         the disability of the Borrower, any other Guarantor, any other
         guarantor of the Guaranteed Obligations or any other party, or the
         unenforceability of the Guaranteed Obligations or any part thereof from
         any cause, or the cessation from any cause of the liability of the
         Borrower other than payment in full of the Guaranteed Obligations. The
         Secured Creditors may, at their election, foreclose on any security
         held by the Administrative Agent, the Collateral Agent or the other
         Secured Creditors by one or more judicial or nonjudicial sales, whether
         or not every aspect of any such sale is commercially reasonable, or
         exercise any other right or remedy the Secured Creditors may have
         against the Borrower or any other party, or any security, without
         affecting or impairing in any way the liability of any Guarantor
         hereunder except to the extent the Guaranteed Obligations have been
         paid in full in cash. Each Guarantor waives any defense arising out of
         any such election by the Secured Creditors, even though such election
         operates to impair or extinguish any right of reimbursement or
         subrogation or other right or remedy of such Guarantor against the
         Borrower or any other party or any security.

                                      -5-


                  (b)      Each Guarantor waives all presentments, demands for
         performance, protests and notices, including, without limitation,
         notices of nonperformance, notices of protest, notices of dishonor,
         notices of acceptance of this Guaranty, and notices of the existence,
         creation or incurring of new or additional indebtedness. Each Guarantor
         assumes all responsibility for being and keeping itself informed of the
         Borrower's financial condition and assets, and of all other
         circumstances bearing upon the risk of nonpayment of the Guaranteed
         Obligations and the nature, scope and extent of the risks which such
         Guarantor assumes and incurs hereunder, and agrees that the Secured
         Creditors shall have no duty to advise any Guarantor of information
         known to them regarding such circumstances or risks.

                  10.      The Secured Creditors agree that this Guaranty may be
enforced only by the action of the Administrative Agent or the Collateral Agent,
in each case acting upon the instructions of the Required Lenders (or, after the
date on which all Credit Document Obligations have been paid in full, the
holders of at least the majority of the outstanding Other Obligations) and that
no other Secured Creditors shall have any right individually to seek to enforce
or to enforce this Guaranty or to realize upon the security to be granted by the
Security Documents, it being understood and agreed that such rights and remedies
may be exercised by the Administrative Agent or the Collateral Agent or, after
all the Credit Document Obligations have been paid in full, by the holders of at
least a majority of the outstanding Other Obligations, as the case may be, for
the benefit of the Secured Creditors upon the terms of this Guaranty and the
Security Documents. The Secured Creditors further agree that this Guaranty may
not be enforced against any director, officer, employee, partner, member or
stockholder of any Guarantor (except to the extent such partner, member or
stockholder is also a Guarantor hereunder).

                  11.      In order to induce the Lenders to make Loans to, and
issue Letters of Credit for the account of, the Borrower pursuant to the Credit
Agreement, and in order to induce the Other Creditors to execute, deliver and
perform the Interest Rate Protection Agreements and Other Hedging Agreements,
each Guarantor represents, warrants and covenants that:

                  (a)      Such Guarantor (i) is a duly organized and validly
         existing corporation, partnership or limited liability company, as the
         case may be, in good standing under the laws of the jurisdiction of its
         organization, (ii) has the corporate, partnership or limited liability
         company, power and authority, as the case may be, to own its property
         and assets and to transact the business in which it is engaged and
         presently proposes to engage and (iii) is duly qualified and is
         authorized to do business and is in good standing in each jurisdiction
         where the conduct of its business requires such qualification except
         for failures to be so qualified which, individually or in the
         aggregate, could not reasonably be expected to have a Material Adverse
         Effect.

                  (b)      Such Guarantor has the corporate, partnership or
         limited liability company, power and authority, as the case may be, to
         execute, deliver and perform the terms and provisions of this Guaranty
         and each other Credit

                                      -6-


         Document to which it is a party and has taken all necessary corporate,
         partnership or limited liability company, action, as the case may be,
         to authorize the execution, delivery and performance by it of this
         Guaranty and each such other Credit Document. Such Guarantor has duly
         executed and delivered this Guaranty and each other Credit Document to
         which it is a party, and this Guaranty and each such other Credit
         Document constitutes the legal, valid and binding obligation of such
         Guarantor enforceable in accordance with its terms, except to the
         extent that the enforceability hereof or thereof may be limited by
         applicable bankruptcy, insolvency, reorganization, moratorium or other
         similar laws generally affecting creditors' rights and by equitable
         principles (regardless of whether enforcement is sought in equity or at
         law).

                  (c)      Neither the execution, delivery or performance by
         such Guarantor of this Guaranty or any other Credit Document to which
         it is a party, nor compliance by it with the terms and provisions
         hereof and thereof, will (i) contravene any provision of any applicable
         law, statute, rule or regulation or any applicable order, writ,
         injunction or decree of any court or governmental instrumentality, (ii)
         conflict with or result in any breach of any of the terms, covenants,
         conditions or provisions of, or constitute a default under, or result
         in the creation or imposition of (or the obligation to create or
         impose) any Lien (except pursuant to the Security Documents) upon any
         of the property or assets of such Guarantor or any of its Subsidiaries
         pursuant to the terms of any indenture, mortgage, deed of trust, loan
         agreement, credit agreement, or any other material agreement, contract
         or instrument to which such Guarantor or any of its Subsidiaries is a
         party or by which it or any of its property or assets is bound or to
         which it may be subject or (iii) violate any provision of the
         certificate of incorporation or by-laws (or equivalent organizational
         documents) of such Guarantor or any of its Subsidiaries.

                  (d)      No order, consent, approval, license, authorization
         or validation of, or filing, recording or registration with (except as
         have been obtained or made) or exemption by, any governmental or public
         body or authority, or any subdivision thereof, is required to
         authorize, or is required for, (i) the execution, delivery and
         performance of this Guaranty by such Guarantor or any other Credit
         Document to which such Guarantor is a party or (ii) the legality,
         validity, binding effect or enforceability of this Guaranty or any
         other Credit Document to which such Guarantor is a party.

                  (e)      There are no actions, suits or proceedings pending
         or, to such Guarantor's knowledge, threatened (i) with respect to this
         Guaranty or any other Credit Document to which such Guarantor is a
         party or (ii) with respect to such Guarantor or any of its Subsidiaries
         that, either individually or in the aggregate, could reasonably be
         expected to have a Material Adverse Effect.

                  12.      Each Guarantor covenants and agrees that on and after
the Effective Date and until the termination of the Total Commitment and all
Interest Rate Protection Agreements and Other Hedging Agreements and until such
time as no Note or

                                      -7-


Letter of Credit remains outstanding and all Guaranteed Obligations have been
paid in full, such Guarantor will comply, and will cause each of its
Subsidiaries to comply, with all of the applicable provisions, covenants and
agreements contained in Articles 9 and 10 of the Credit Agreement, and will
take, or will refrain from taking, as the case may be, all actions that are
necessary to be taken or not taken so that it is not in violation of any
provision, covenant or agreement contained in Articles 9 or 10 of the Credit
Agreement, and so that no Default or Event of Default, is caused by the actions
of such Guarantor or any of its Subsidiaries.

                  13.      The Guarantors hereby jointly and severally agree to
pay all reasonable out-of-pocket costs and expenses of each Secured Creditor in
connection with the enforcement of this Guaranty and of the Administrative Agent
in connection with any amendment, waiver or consent relating hereto (including
in each case, without limitation, the reasonable fees and disbursements of
counsel employed by each Secured Creditor).

                  14.      This Guaranty shall be binding upon each Guarantor
and its successors and assigns and shall inure to the benefit of the Secured
Creditors and their successors and assigns.

                  15.      Neither this Guaranty nor any provision hereof may be
changed, waived, discharged or terminated except with the written consent of
each Guarantor directly affected thereby and with the written consent of either
(x) the Required Lenders (or to the extent required by Section 13.11 of the
Credit Agreement, with the written consent of each Lender) at all times prior to
the time on which all Credit Document Obligations have been paid in full or (y)
the holders of at least a majority of the outstanding Other Obligations at all
times after the time on which all Credit Document Obligations have been paid in
full; provided, that any change, waiver, modification or variance affecting the
rights and benefits of a single Class (as defined below) of Secured Creditors
(and not all Secured Creditors in a like or similar manner) shall also require
the written consent of the Requisite Creditors (as defined below) of such Class
of Secured Creditors (it being understood that the addition or release of any
Guarantor hereunder shall not constitute a change, waiver, discharge or
termination affecting any Guarantor other than the Guarantor so added or
released). For the purpose of this Guaranty, the term "Class" shall mean each
class of Secured Creditors, i.e., whether (x) the Lender Creditors as holders of
the Credit Document Obligations or (y) the Other Creditors as the holders of the
Other Obligations. For the purpose of this Guaranty, the term "Requisite
Creditors" of any Class shall mean (x) with respect to the Credit Document
Obligations, the Required Lender (or to the extent required by Section 13.11 of
the Credit Agreement, each Lender) and (y) with respect to the Other
Obligations, the holders of at least a majority of all obligations outstanding
from time to time under the Interest Rate Protection or Other Hedging
Agreements.

                  16.      Each Guarantor acknowledges that an executed (or
conformed) copy of each of the Credit Documents and Interest Rate Protection
Agreements or Other Hedging Agreements has been made available to a senior
officer of such Guarantor and such officer is familiar with the contents
thereof.

                                      -8-


                  17.      In addition to any rights now or hereafter granted
under applicable law and not by way of limitation of any such rights, upon the
occurrence and during the continuance of an Event of Default (such term to mean
and include any "Event of Default" as defined in the Credit Agreement or any
payment default under any Interest Rate Protection Agreement or Other Hedging
Agreement continuing after any applicable grace period), each Secured Creditor
is hereby authorized, at any time or from time to time, without notice to any
Guarantor or to any other Person, any such notice being expressly waived, to set
off and to appropriate and apply any and all deposits (general or special) and
any other indebtedness at any time held or owing by such Secured Creditor to or
for the credit or the account of such Guarantor, against and on account of the
obligations and liabilities of such Guarantor to such Secured Creditor under
this Guaranty, irrespective of whether or not such Secured Creditor shall have
made any demand hereunder and although said obligations, liabilities, deposits
or claims, or any of them, shall be contingent or un-matured.

                  18.      All notices, requests, demands or other
communications pursuant hereto shall be sent or delivered by mail, telegraph,
telex, telecopy, cable or overnight courier service and all such notices and
communications shall, when mailed, telegraphed, telexed, telecopied, or cabled

delivered to the telegraph company, cable company or overnight courier, as the
case may be, or sent by telex or telecopier and when mailed shall be effective
three Business Days following deposit in the mail with proper postage, except
that notices and communications to the Administrative Agent or any Guarantor
shall not be effective until received by the Administrative Agent or such
Guarantor, as the case may be. All notices and other communications shall be in
writing and addressed to such party at (i) in the case of any Lender Creditor,
as provided in the Credit Agreement, (ii) in the case of any Guarantor, as
provided in the Security Agreement and (iii) in the case of any Other Creditor,
at such address as such Other Creditor shall have specified in writing to the
Guarantors; or in any case at such other address as any of the Persons listed
above may hereafter notify the others in writing.

                  19.      If claim is ever made upon any Secured Creditor for
repayment or recovery of any amount or amounts received in payment or on account
of any of the Guaranteed Obligations and any of the aforesaid payees repays all
or part of said amount by reason of (i) any judgment, decree or order of any
court or administrative body having jurisdiction over such payee or any of its
property or (ii) any settlement or compromise of any such claim effected by such
payee with any such claimant (including the Borrower) then and in such event
each Guarantor agrees that any such judgment, decree, order, settlement or
compromise shall be binding upon such Guarantor, notwithstanding any revocation
hereof or other instrument evidencing any liability of the Borrower, and such
Guarantor shall be and remain liable to the aforesaid payees hereunder for the
amount so repaid or recovered to the same extent as if such amount had never
originally been received by any such payee.

                  20.      (a)      THIS GUARANTY AND THE RIGHTS AND OBLIGATIONS
         OF THE SECURED CREDITORS AND OF THE UNDERSIGNED HEREUNDER SHALL BE
         GOVERNED BY AND

                                      -9-


         CONSTRUED IN ACCORDANCE WITH THE LAW OF THE STATE OF MINNESOTA. Any
         legal action or proceeding with respect to this Guaranty or any other
         Credit Document to which any Guarantor is a party may be brought in the
         courts of the State of Minnesota or of the United States of America for
         the District of Minnesota, and, by execution and delivery of this
         Guaranty, each Guarantor hereby irrevocably accepts for itself and in
         respect of its property, generally and unconditionally, the
         jurisdiction of the aforesaid courts. Each Guarantor hereby further
         irrevocably waives any claim that any such court lacks personal
         jurisdiction over such Guarantor, and agrees not to plead or claim in
         any legal action or proceeding with respect to this Guaranty or any
         other Credit Document to which such Guarantor is a party brought in any
         of the aforesaid courts that any such court lacks personal jurisdiction
         over such Guarantor. Each Guarantor further irrevocably consents to the
         service of process out of any of the aforementioned courts in any such
         action or proceeding by the mailing of copies thereof by registered or
         certified mail, postage prepaid, to such Guarantor at its address set
         forth opposite its signature below, such service to become effective 30
         days after such mailing. Each Guarantor hereby irrevocably waives any
         objection to such service of process and further irrevocably waives and
         agrees not to plead or claim in any action or proceeding commenced
         hereunder or under any other Credit Document to which such Guarantor is
         a party that such service of process was in any way invalid or
         ineffective. Nothing herein shall affect the right of any of the
         Secured Creditors to serve process in any other manner permitted by law
         or to commence legal proceedings or otherwise proceed against each
         Guarantor in any other jurisdiction.

                  (b)      Each Guarantor hereby irrevocably waives (to the
         fullest extent permitted by applicable law) any objection which it may
         now or hereafter have to the laying of venue of any of the aforesaid
         actions or proceedings arising out of or in connection with this
         Guaranty or any other Credit Document to which such Guarantor is a
         party brought in the courts referred to in clause (a) above and hereby
         further irrevocably waives and agrees not to plead or claim in any such
         court that such action or proceeding brought in any such court has been
         brought in an inconvenient forum.

                  (c)      EACH GUARANTOR AND EACH SECURED CREDITOR (BY ITS
         ACCEPTANCE OF THE BENEFITS OF THIS GUARANTY) HEREBY IRREVOCABLY WAIVES
         ALL RIGHTS TO A TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM
         ARISING OUT OF OR RELATING TO THIS GUARANTY, THE OTHER CREDIT DOCUMENTS
         TO WHICH SUCH GUARANTOR IS A PARTY OR THE TRANSACTIONS CONTEMPLATED
         HEREBY OR THEREBY.

                  21.      In the event that all of the capital stock of one or
more Guarantors is sold or otherwise disposed of or liquidated in compliance
with the requirements of Section 10.2 of the Credit Agreement (or such sale or
other disposition has been approved in writing by the Required Lenders (or all
Lenders if required by Section 13.11 of the Credit Agreement)) and the proceeds
of such sale, disposition or liquidation are

                                      -10-


applied in accordance with the provisions of the Credit Agreement, to the extent
applicable, such Guarantor shall upon consummation of such sale or other
disposition (except to the extent that such sale or disposition is to the
Borrower or another Subsidiary thereof) be released from this Guaranty
automatically and without further action and this Guaranty shall, as to each
such Guarantor or Guarantors, terminate, and have no further force or effect (it
being understood and agreed that the sale of one or more Persons that own,
directly or indirectly, all of the capital stock of any Guarantor shall be
deemed to be a sale of such Guarantor for the purposes of this Section 21).

                  22.      At any time a payment in respect of the Guaranteed
Obligations is made under this Guaranty, the right of contribution of each
Guarantor against each other Guarantor shall be determined as provided in the
immediately following sentence, with the right of contribution of each Guarantor
to be revised and restated as of each date on which a payment (a "Relevant
Payment") is made on the Guaranteed Obligations under this Guaranty. At any time
that a Relevant Payment is made by a Guarantor that results in the aggregate
payments made by such Guarantor in respect of the Guaranteed Obligations to, and
including the date of the Relevant Payment exceeding such Guarantor's
Contribution Percentage (as defined below) of the aggregate payments made by all
Guarantors in respect of the Guaranteed Obligations to and including the date of
the Relevant Payment (such excess, the "Aggregate Excess Amount"), each such
Guarantor shall have a right of contribution against each other Guarantor who
has made payments in respect of the Guaranteed Obligations to and including the
date of the Relevant Payment in an aggregate amount less than such other
Guarantor's Contribution Percentage of the aggregate payments made to and
including the date of the Relevant Payment by all Guarantors in respect of the
Guaranteed Obligations (the aggregate amount of such deficit, the "Aggregate
Deficit Amount") in an amount equal to (x) a fraction the numerator of which is
the Aggregate Excess Amount of such Guarantor and the denominator of which is
the Aggregate Excess Amount of all Guarantors multiplied by (y) the Aggregate
Deficit Amount of such other Guarantor. A Guarantor's right of contribution
pursuant to the preceding sentences shall arise at the time of each computation,
subject to adjustment to the time of each computation; provided, that no
Guarantor may take any action to enforce such right until the Guaranteed
Obligations have been irrevocably paid in full in cash, it being expressly
recognized and agreed by all parties hereto that any Guarantor's right of
contribution arising pursuant to this Section 22 against any other Guarantor
shall be expressly junior and subordinate to such other Guarantor's obligations
and liabilities in respect of the Guaranteed Obligations and any other
obligations owing under this Guaranty. As used in this Section 22: (i) each
Guarantor's "Contribution Percentage" shall mean the percentage obtained by
dividing (x) the Adjusted Net Worth (as defined below) of such Guarantor by (y)
the aggregate Adjusted Net Worth of all Guarantors; (ii) the "Adjusted Net
Worth" of each Guarantor shall mean the greater of (x) the Net Worth (as defined
below) of such Guarantor and (y) zero; and (iii) the "Net Worth" of each
Guarantor shall mean the amount by which the fair salable value of such
Guarantor's assets on the date of any Relevant Payment exceeds its existing
debts and other liabilities (including contingent liabilities, but without
giving effect to any Guaranteed Obligations arising under this Guaranty) on such
date. All parties hereto recognize and agree that, except for any right of
contribution arising pursuant to this Section 22, each Guarantor who makes any
payment in respect of the

                                      -11-


Guaranteed Obligations shall have no right of contribution or subrogation
against any other Guarantor in respect of such payment until all of the
Guaranteed Obligations have been irrevocably paid in full in cash. Each of the
Guarantors recognizes and acknowledges that the rights to contribution arising
hereunder shall constitute an asset in favor of the party entitled to such
contribution. In this connection, each Guarantor has the right to waive its
contribution right against any Guarantor to the extent that after giving effect
to such waiver such Guarantor would remain solvent, in the determination of the
Required Lenders.

                  23.      Each Guarantor and each Secured Creditor (by its
acceptance of the benefits of this Guaranty) hereby confirms that it is its
intention that this Guaranty not constitute a fraudulent transfer or conveyance
for purposes of the Bankruptcy Code, the Uniform Fraudulent Conveyance Act of
any similar Federal or state law. To effectuate the foregoing intention, each
Guarantor and each Secured Creditor (by its acceptance of the benefits of this
Guaranty) hereby irrevocably agrees that the Guaranteed Obligations guaranteed
by such Guarantor shall be limited to such amount as will, after giving effect
to such maximum amount and all other (contingent or otherwise) liabilities of
such Guarantor that are relevant under such laws, and after giving effect to any
rights to contribution pursuant to any agreement providing for an equitable
contribution among such Guarantor and other Guarantors, result in the Guaranteed
Obligations of such Guarantor in respect of such maximum amount not constituting
a fraudulent transfer or conveyance.

                  24.      This Guaranty may be executed in any number of
counterparts and by the different parties hereto on separate counterparts, each
of which when so executed and delivered shall be an original, but all of which
shall together constitute one and the same instrument. A set of counterparts
executed by all the parties hereto shall be lodged with the Guarantors and the
Administrative Agent.

                  25.      All payments made by any Guarantor hereunder will be
made without setoff, counterclaim or other defense and on the same basis as
payments are made by the Borrower under Sections 5.3 and 5.4 of the Credit
Agreement.

                  26.      It is understood and agreed that any Subsidiary of
the Borrower that is required to execute a counterpart of this Guaranty after
the date hereof pursuant to the Credit Agreement shall become a Guarantor
hereunder by executing a counterpart hereof and delivering the same to the
Administrative Agent.

                  27.      Each Guarantor has independently, and without
reliance on any information supplied by any Secured Creditor, taken, and will
continue to take, whatever steps it deems necessary to evaluate the financial
condition and affairs of the Borrower or any Collateral, and the Secured
Creditors shall have no duty to advise any Guarantor of information at any time
known to them regarding such financial condition or affairs or any Collateral.

be executed and delivered as of the date first above written.
