                       DOMESTIC SUBSIDIARIES' GUARANTEE

        DOMESTIC SUBSIDIARIES' GUARANTEE, dated as of March 6, 1996 (this
"Guarantee"), made by each of the corporations that are signatories hereto (the
"Guarantors"), in favor of CHEMICAL BANK, as agent (in such capacity, the
"Agent") for the lenders (the "Lenders") from time to time parties to the
Credit Agreement, dated as of Feb. 29, 1996 (as amended, amended and restated,
supplemented or otherwise modified from time to time, the "Credit Agreement"),
among Berg Electronics Group, Inc. (the "Borrower"), Berg Electronics Corp.,
the Lenders and the Agent.

                                 WITNESSETH:


        WHEREAS, pursuant to the Credit Agreement, the Lenders have agreed to
make loans to, and issue or participate in letters of credit for the account of,
the Borrower upon the terms and subject to the conditions set forth therein;

        WHEREAS, the Borrower owns directly or indirectly all of the issued and
outstanding stock of each Guarantor.

        WHEREAS, the Borrower and the Guarantors are engaged in related
businesses, and each Guarantor will derive substantial direct and indirect
benefit from the making of the loans to, and the issuing of the letters of
credit for the account of, the Borrower under the Credit Agreement; and

        WHEREAS, it is a condition precedent to the obligation of the Lenders
to make their respective loans to, and issue letters of credit for the account
of, the Borrower under the Credit Agreement that the Guarantors shall have
executed and delivered this Guarantee to the Agent for the ratable benefit of
the Lenders.

        NOW, THEREFORE, in consideration of the premises and to induce the
Agent and the Lenders to enter into the Credit Agreement and to induce the
Lenders to make their respective loans to, and issue or participate in letters
of credit for the account of, the Borrower under the Credit Agreement, the
Guarantors hereby agree with the Agent, for the ratable benefit of the Lenders,
as follows:

        1. Defined Terms. Unless otherwise defined herein, terms defined in the
Credit Agreement and used herein shall have the meanings given to such terms in
the Credit Agreement.

                                                                               2



        2. Guarantee.  (a) Subject to the provisions of paragraph 2(b), each of
the Guarantors hereby, jointly and severally, unconditionally and irrevocably,
guarantees to the Agent, for the ratable benefit of the Lenders and their
respective successors, indorsees, transferees and assigns, the prompt and
complete payment and performance by the Borrower when due (whether at the
stated maturity, by acceleration or otherwise) of the Obligations.

        (b)  Anything herein or in any other Loan Document to the contrary
notwithstanding, the maximum liability of each Guarantor hereunder and under
the other Loan Documents shall in no event exceed the amount which can be
guaranteed by such Guarantor under applicable federal and state laws relating
to the insolvency of debtors.

        (c)  Each Guarantor further agrees to pay the reasonable out-of-pocket
expenses which may be paid or incurred by the Agent or the Lenders in
collecting any or all of the Obligations and/or enforcing any rights under this
Guarantee or under the Obligations in accordance with subsection 12.5 of the
Credit Agreement. This Guarantee shall remain in full force and effect until
the Obligations are paid in full and the Commitments are terminated,
notwithstanding that from time to time prior thereto the Borrower may be free
from any Obligations.

        (d)  Each Guarantor agrees that the Obligations may at any time and
from time to time exceed the amount of the liability of such Guarantor
hereunder without impairing this Guarantee or affecting the rights and remedies
of the Agent or any Lender hereunder.

        (e)  No payment or payments made by the Borrower, any of the
Guarantors, any other guarantor or any other Person or received or collected by
the Agent, the Issuing Lender or the Lenders from the Borrower, any of the
Guarantors, any other guarantor or any other Person by virtue of any action or
proceeding or any set-off or appropriation or application at any time or from
time to time in reduction of or in payment of the Obligations shall be deemed
to modify, reduce, release or otherwise affect the liability of any Guarantor
hereunder which shall, notwithstanding any such payment or payments other than
payments made by such Guarantor in respect of the Obligations or payments 
received or collected from such Guarantor in respect of the Obligations, 
remain liable for the Obligations up to the maximum liability of such Guarantor
hereunder until the Obligations are paid in full and the Commitments are 
terminated.

        (f)  Each Guarantor agrees that whenever, at any time, or from time to
time, it shall make any payment to the Agent, the Issuing Lender or the 
Lenders on account of its liability hereunder, it will notify the Agent in 
writing that such payment is made under this Guarantee for such purpose.

        3.  Right of Contribution.  Each Guarantor hereby agrees that to the
extent that a Guarantor shall have paid more than its proportionate share of
any payment made hereunder, such Guarantor shall be entitled to seek and
receive contribution from and against any other Guarantor hereunder who has not
paid its proportionate share of such payment. Each Guarantor's right of
contribution shall be subject to the terms and conditions of Section 5 hereof.
The provisions of this Section 3 shall in no respect limit the obligations and
liabilities

                                                                               3



of any Guarantor to the Agent, the Issuing Lender and the Lenders, and each
Guarantor shall remain liable to the Agent, the Issuing Lender and the Lenders
for the full amount guaranteed by such Guarantor hereunder.

        4. Right of Set-off. Upon the occurrence of any Event of Default, each
Guarantor hereby irrevocably authorizes each Lender and the Issuing Lender at
any time and from time to time without notice to such Guarantor or any other
Guarantor, any such notice being expressly waived by each Guarantor, to set-off
and appropriate and apply any and all deposits (general or special, time or
demand, provisional or final), in any currency, and any other credits,
indebtedness or claims, in any currency, in each case whether direct or
indirect, absolute or contingent, matured or unmatured, at any time held or
owing by such Lender or the Issuing Lender or any branch or agency thereof to
or for the credit or the account of such Guarantor, or any part thereof in such
amounts as such Lender or the Issuing Lender may elect, against and on account
of the obligations and liabilities of such Guarantor to such Lender or the
Issuing Lender hereunder and claims of every nature and description of such
Lender or the Issuing Lender against such Guarantor, in any currency, whether
arising hereunder, under the Credit Agreement, any Note, any Loan Document or
otherwise, as such Lender or the Issuing Lender may elect, whether or not the
Agent, the Issuing Lender or the Lenders have made any demand for payment and
although such obligations, liabilities and claims may be contingent or
unmatured. The Agent, the Issuing Lender and the Lenders agree promptly to
notify such Guarantor after any such set-off and the application made by the
Agent, the Issuing Lender or the Lenders, as the case may be; provided that
the failure to give such notice shall not affect the validity of such set-off
and application. The rights of the Agent, the Issuing Lender and the Lenders
under this Section 4 are in addition to other rights and remedies (including,
without limitation, other rights of set-off) which the Agent, the Issuing
Lender or the Lenders may have.

        5. No Subrogation. Notwithstanding any payment or payments made by any
of the Guarantors hereunder or any set-off or application of funds of any of
the Guarantors by any Lender, no Guarantor shall be entitled to be subrogated
to any of the rights of the Agent, the Issuing Lender or the Lenders against
the Borrower or any other Guarantor or any collateral security or guarantee or
right of offset held by the Agent, the Issuing Lender or the Lenders for the
payment of the Obligations, nor shall any Guarantor seek or be entitled to seek
any contribution or reimbursement from the Borrower or any other Guarantor in
respect of payments made by such Guarantor hereunder, until all amounts owing
to the Agent, the Issuing Lender and the Lenders by the Borrower on account of
the Obligations are paid in full and the Commitments are terminated. If any
amount shall be paid to any Guarantor on account of such subrogation rights at
any time when all of the Obligations shall not have been paid in full, such
amount shall be held by such Guarantor in trust for the Agent, the Issuing
Lender and the Lenders, segregated from other funds of such Guarantor, and
shall, forthwith upon receipt by such Guarantor, be turned over to the Agent in
the exact form received by such Guarantor (duly indorsed by such Guarantor to
the Agent, if required), to be applied against the Obligations, whether
matured or unmatured, in such order as the Agent may determine.

        6. Modification of Obligations. Each Guarantor consents that, without
the necessity of any reservation of rights against any Guarantor and without
notice to or further assent by any Guarantor, any demand for payment of any of
the Obligations made by the Agent, the Issuing Lender or the Lenders may be
rescinded by the Agent, the Issuing Lender or the Lenders and the Obligations
continued, and the Obligations, or the liability of any other party upon or for
any part thereof, or any collateral security or guarantee therefor or right of
offset with respect thereto, may, from time to time, in whole or in part, be
renewed, extended, amended, modified, accelerated, compromised, waived,
surrendered or released by the Agent, the Issuing Lender or the Lenders, and
the Credit Agreement, any Notes and the other Loan Documents, including,
without limitation, any Letter of Credit Application, or any collateral
security document or other guarantee or document in connection therewith may be
amended, modified, supplemented or terminated, in whole or in part, as the
Agent, the Issuing Lender or the Lenders may deem advisable from time to time,
and, to the extent permitted by applicable law, any collateral security or
guarantee or right of offset at any time held by the Agent, the Issuing Lender 
or the Lenders for the payment of the Obligations may be sold, exchanged,
waived, surrendered or released, all without the necessity of any reservation
of rights against any Guarantor which will remain bound hereunder
notwithstanding any such renewal, extension, modification, acceleration,
compromise, amendment, supplement, termination, sale, exchange, waiver,
surrender or release. The Agent, the Issuing Lender and the Lenders shall not
have any obligation to protect, secure, perfect or insure any collateral
security document or property subject thereto at any time held by it as
security for the Obligations or for this Guarantee or any property subject
thereto. When making any demand hereunder against any of the Guarantors, the
Agent, the Issuing Lender or the Lenders may, but shall be under no obligation
to, make a similar demand on any other party or any other Guarantor or
guarantor, and any failure by the Agent, the Issuing Lender or the Lenders to
make any such demand or to collect any payments from the Borrower or any such
other Guarantor or guarantor shall not relieve any of the Guarantors in respect
of which a demand or collection is not made of their several obligations or
liabilities hereunder, and shall not impair or affect the rights and remedies,
express or implied, or as a matter of law, of the Agent, the Issuing Lender or
the Lenders against any of the Guarantors. For the purposes hereof "demand"
shall include the commencement and continuance of any legal proceedings.

        7. Guarantee Absolute and Unconditional. Each Guarantor waives any and
all notice of the creation, renewal, extension or accrual of any of the
Obligations and notice of or proof of reliance by the Agent, the Issuing 
Lender or the Lenders upon this Guarantee or acceptance of this Guarantee, the
Obligations, and any of them, shall conclusively be deemed to have been
created, contracted, continued or incurred in reliance upon this Guarantee; and
all dealings between the Borrower and any of the Guarantors, on the one hand,
and the Agent, the Issuing Lender or the Lenders, on the other hand, likewise
shall be conclusively presumed to have been had or consummated in reliance upon
this Guarantee. Each Guarantor waives diligence, presentment, protest, demand
for payment and notice of default or nonpayment to or upon any of the
Guarantors with respect to the Obligations. This Guarantee shall be construed
as a continuing, absolute and unconditional guarantee of payment without regard
to the validity, regularity or enforceability of the Credit Agreement, any Note
or any other Loan Document, including, without limitation, any Letter of Credit
Application or any collateral security or guarantee therefor or right of offset
with respect thereto at any time or from time

                                                                             5

to time held by the Agent, the Issuing Lender or the Lenders and without regard
to any defense, set-off or counterclaim which may at any time be available to
or be asserted by the Borrower against the Agent, the Issuing Lender, the
Lenders or any other Person, or by any other circumstance whatsoever (with or
without notice to or knowledge of the Borrower or such Guarantor) which
constitutes, or might be construed to constitute, an equitable or legal
discharge of the Borrower for any of the Obligations (other than payment in
money or money's worth and termination of the Commitments), or of such
Guarantor under this Guarantee, in bankruptcy or in any other instance and the
obligations and liabilities of such Guarantor hereunder shall not be
conditioned or contingent upon the pursuit by the Agent, the Issuing Lender or
the Lenders or any other Person at any time of any right or remedy against the
Borrower or against any other Person which may be or become liable in respect
of any Obligations or against any collateral security or guarantee therefor or
right of offset with respect thereto.  This Guarantee shall remain in full
force and effect and be binding in accordance with and to the extent of its
terms upon each Guarantor and the successors and assigns thereof, and shall
inure to the benefit of the Agent and the Lenders, and their respective
successors, endorsees, transferees and assigns, until all the Obligations and
the obligations of each Guarantor under this Guarantee shall have been
satisfied by payment in full and the Commitments shall be terminated,
notwithstanding that from time to time during the term of the Credit Agreement
the Borrower may be free from any Obligations.

        8.  Reinstatement.  This Guarantee shall continue to be effective, or
be reinstated, as the case may be, if at any time payment, or any part thereof,
of any of the Obligations is rescinded or must otherwise be restored or
returned by the Agent, the Issuing Lender or the Lenders upon the insolvency,
bankruptcy, dissolution, liquidation or reorganization of the Borrower or any
Guarantor, or upon or as a result of the appointment of a receiver, intervenor
or conservator of, or trustee or similar officer for, the Borrower or any
Guarantor or any substantial part of its property, or otherwise, all as though
such payments had not been made.

        9.  Payments.  Each Guarantor hereby guarantees that payments hereunder
will be paid to the Agent without set-off or counterclaim in Dollars at the
office of the Agent located at 270 Park Avenue, New York, New York 10017.

        10.  Representations and Warranties.  Each Guarantor hereby represents

bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium or
similar laws affecting the enforcement of creditors' rights generally (whether
enforcement is sought by proceedings in equity or at law);

        (d)  the execution, delivery and performance of this Guarantee will not
violate any provision of any material Requirement of Law or material
Contractual Obligation of such Guarantor and will not result in the creation or

Guarantor pursuant to any Requirement of Law or Contractual Obligation of the
Guarantor, except as set forth in the Credit Agreement;

        (e)  no consent or authorization of, filing with, or other act by or in

each borrowing by, or issuance of a Letter of Credit for the account of, the
Borrower under the Credit Agreement on and as of such date of borrowing or
issuance as though made hereunder on and as of such date, except to the extent
they related to a specified date in which case they shall be true and correct
as of such date.

        11.  Authority of Agent.  Each Guarantor acknowledges that the rights
and responsibilities of the Agent under this Guarantee with respect to any
action taken by the Agent or the exercise or non-exercise by the Agent of any
option, right, request, judgment or other right or remedy provided for herein
or resulting or arising out of this Guarantee shall, as between the Agent and
the Lenders, be governed by the Credit Agreement and by such other agreements
with respect thereto as may exist from time to time among them, but, as between
the Agent and such Guarantor, the Agent shall be conclusively presumed to be
acting as agent for the Lenders with full and valid authority so to act or
refrain from acting, and no Guarantor shall be under any obligation, or
entitlement, to make any inquiry respecting such authority.

        12.  Notices.  All notices, requests and demands to or upon the Agent,
any Lender or any Guarantor to be effective shall be in writing (or by telex,

<PAGE>   7
                                                                               7




        (a)     if to the Agent or any Lender, at its address or transmission
number for notices provided in subsection 12.2 of the Credit Agreement; and

        (b)     if to any Guarantor, at its address or transmission number for
notices set forth under its signature below.

        The Agent, each Lender and each Guarantor may change its address and
transmission numbers for notices by notice in the manner provided in this
Section 12. 

        13.     Counterparts.  This Guarantee may be executed by one or more of
the Guarantors on any number of separate counterparts, and all of said
counterparts taken together shall be deemed to constitute one and the same
instrument. A set of the counterparts of this Guarantee signed by all the
Guarantors shall be lodged with the Agent. 

        14.     Severability.  Any provision of this Guarantee which is
prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction,
be ineffective to the extent of such prohibition or unenforceability without

unenforceability in any jurisdiction shall not invalidate or render
unenforceable such provision in any other jurisdiction. 

        15.     Integration.  This Guarantee represents the agreement of each
Guarantor with respect to the subject matter hereof and there are no promises
or representations by the Agent or any Lender relative to the subject matter
hereof not reflected herein. 

        16.     Amendments in Writing; No Waiver; Cumulative Remedies.  (a)
None of the terms or provisions of this Guarantee may be waived, amended,
supplemented or otherwise modified except by a written instrument executed by
each Guarantor and the Required Lenders. 

        (b)     Neither the Agent nor any Lender shall by any act (except by a
written instrument pursuant to paragraph 16(a) hereof), delay, indulgence,
omission or otherwise be deemed to have waived any right or remedy hereunder or
to  have acquiesced in any Default or Event of Default or in any breach of any
of the terms and conditions hereof. No failure to exercise, nor any delay in
exercising, on the part of the Agent or any Lender, any right, power or
privilege hereunder shall operate as a waiver thereof. No single or partial
exercise of any right, power or privilege hereunder shall preclude any other or
further exercise thereof or the exercise of any other right, power or
privilege. A waiver by the Agent or any Lender of any right or remedy
hereunder on any one occasion shall not be construed as a bar to any right or
remedy which the Agent or such Lender would otherwise have on any future
occasion. 

        (c)     The rights and remedies herein provided are cumulative, may be
exercised singly or concurrently and are not exclusive of any other rights or

                (c)     agrees that service of process in any such action or

        been notified pursuant to Section 12;

                (d)     agrees that nothing herein shall affect the right to
        effect service of process in any other manner permitted by law or shall
        limit the right to sue in any other jurisdiction; and

                (e)     waives, to the maximum extent not prohibited by law,
        any right it may have to claim or recover in any legal action or
        proceeding referred to in this Section any special, exemplary, punitive
        or consequential damages.
