     WHEREAS, Lernout & Hauspie Speech Products NV, a Belgian limited liability
company ("Obligor"), on the one hand, has entered into a Revolving Credit
Facility Agreement dated as of May 2, 2000 (the "Credit Agreement") with, on the
other hand, KBC Bank NV and Fortis Bank NV as Lead Arrangers; Artesia Banking
Corporation NV, Deutsche Bank NV and Dresdner Bank Luxembourg SA as Joint
Arrangers; Artesia Banking Corporation NV as Agent for the Tranche A Facility;
KBC Bank NV in its capacity as Agent for the Tranche B Facility and KBC Bank NV,
Artesia Banking Corporation NV, Fortis Bank NV, Deutsche Bank NV and Dresdner
Bank Luxembourg NV (together, the "Lenders"); and

     WHEREAS, as a condition subsequent to Obligor's obligations under the
Credit Agreement, the Lenders have required that Dictaphone Corporation
("Guarantor"), a wholly-owned subsidiary of Obligor and the beneficiary of a
portion of the funds made available to Obligor under the Credit Agreement
(through, among other things, advances Obligor has made or later may make to
Guarantor to enable Guarantor to pay some of its indebtedness existing as of the
date of Obligor's acquisition of Guarantor), guarantee the full and prompt
payment and performance of Obligor's obligations under the Credit Agreement on
the terms and conditions provided herein.

     NOW, THEREFORE, for good and valuable consideration, the receipt and
sufficiency of which is hereby acknowledged, and in consideration of any and all
loans, advances, and extensions of credit now or hereafter made or extended by
Lenders to, for the account of or on behalf of Obligor pursuant to and under the
Credit Agreement, Guarantor hereby unconditionally and absolutely guarantees to
Lenders the full and prompt payment and performance by Obligor of all
obligations which Obligor now or hereafter may have to Lenders of any kind or
nature, whether now existing or hereafter arising, under or evidenced by the
Credit Agreement, in an amount not to exceed $167 million, plus interest
accruing thereon under the Credit Agreement, plus the "Indenture Amount" (as
that term is defined below) (the "Obligations").  The Obligations will decrease
in proportion to (i) the amounts by which the facility made available to the
Obligor under the Credit Agreement is reduced and/or (ii) any amounts under the
facility are cancelled by the Obligor.  "Indenture Amount" shall mean the total
outstanding balance of advances received by Obligor under the Credit Agreement,
which Obligor advances to Guarantor to enable Guarantor to satisfy its
obligations ($200 million principal, plus interest and any applicable premium,
charges and fees) under the following:  (i) Dictaphone Corporation 11  3/4 %
Senior Subordinated Notes due 2005 in the aggregate original principal amount of
$200,000,000 and (ii) that certain Indenture dated as of August 11, 1995 by and
among Dictaphone Corporation and State Street Bank & Trust Company, as successor
to Shawmut Bank Connecticut, National Association, as Trustee.

     Payments due by the Obligor under this Guaranty shall be paid upon receipt
of the Lenders' written demand to that effect, sent by the Agents on behalf of
the Lenders.

in connection with the Obligations.  The Guarantor further waives the following:
notice of incurring of indebtedness and obligations by Obligor; acceptance of
this Guaranty by Lenders; presentment and demand for payment, protest, notice of

notice to or consent of the Guarantor, by any of the following: (a) new
agreements or obligations of Obligor with or to Lenders; (b) amendments,
indulgences, extensions, modifications, renewals or waivers of default as to any
existing or future agreements or obligations of Obligor or third parties with or
to Lenders, or extensions of credit by Lenders to Obligor; (c) adjustments,
compromises or releases of any obligations of Obligor, Guarantor or other
parties, including any other guarantors, or exchanges, releases, dispositions or
sales of any security of Obligor, Guarantor or other parties, including any
other guarantors; (d) invalidity, irregularity, defect, or unenforceability, for
any reason, of any of the Obligations, or of any instrument or writing, or of
any security or other guaranty, or acts or omissions by Lenders or Obligor; (e)
interruptions in the business relations between Lenders and Obligor; (f)
voluntary or involuntary bankruptcy (including a reorganization in bankruptcy)
of Obligor or entry of an order for relief against or with respect to the
Obligor under Title 11 of the United States Code or similar foreign laws; (g)
composition, extension, moratoria or other forms of debtor relief granted to
Obligor pursuant to law presently in force or hereafter enacted; (h) payment of
any or all obligations and indebtedness of Obligor in the event such payment is
invalidated or avoided by a trustee, custodian or receiver of Obligor; (i) the
dissolution of Obligor; and (j) the reorganization, merger or consolidation of
Obligor into or with another entity, corporate or otherwise, or the sale or
disposition of all or substantially all of the capital stock, business or assets
of Obligor to any other person or party.

     For purposes of any action or proceeding involving this Guaranty, Guarantor
hereby expressly submits to the jurisdiction of all federal and state courts
