         NOW, THEREFORE, for good and valuable consideration, the receipt and

guaranties to KCIT the prompt and full
   2
payment of the Indebtedness described in Section 1 below in this Guaranty
(collectively called the "Guaranteed Obligations"), this Guaranty being upon
the following terms and conditions:

1.       GUARANTY OF PAYMENT.  Guarantor hereby unconditionally and irrevocably
         guarantees to KCIT the punctual payment when due, whether by lapse of
         time, by acceleration of maturity, or otherwise, and at all times
         thereafter, of all principal, interest (including interest accruing
         after the commencement of any bankruptcy or insolvency proceeding by
         or against Borrower or PRN as the case may be, whether or not allowed
         in such proceeding), costs, expenses, and other sums of money now or
         hereafter due and owing pursuant to (i) the terms of the Guaranteed
         Notes, and (ii) all renewals, extensions, refinancings, modifications,
         supplements or amendments of such indebtedness or any part thereof
         (the indebtedness described in clauses (i) and (ii) above in this
         Section 1 is herein collectively called the "Indebtedness").  This
         Guaranty covers the Indebtedness, whether presently outstanding or
         arising subsequent to the date hereof.  The guaranty of Guarantor as
         set forth in this Section 1 is a continuing guaranty of payment and
         not a guaranty of collection.

2.       PRIMARY LIABILITY OF GUARANTOR.

         (a)     This Guaranty is an absolute, irrevocable and unconditional
                 guaranty of payment. Guarantor shall be liable for the payment
                 of the Guaranteed Obligations, as set forth in this Guaranty,
                 as a primary obligor.  This Guaranty shall be effective as a
                 waiver of, and Guarantor hereby expressly waives, any and all
                 rights to which Guarantor may otherwise have been entitled
                 under any suretyship laws in effect from time to time.

         (b)     In the event of default by Borrower and/or PRN, in payment of
                 the Guaranteed Obligations, or any part thereof, when such
                 indebtedness becomes due, either by its terms or as the result
                 of the exercise of any power to accelerate, Guarantor shall,
                 on demand and without presentment, protest, notice of
                 acceptance of this Guaranty, protest, further notice of
                 nonpayment or of dishonor or of default or nonperformance, or
                 notice of acceleration or of intent to accelerate, or any
                 other notice whatsoever, make payment in respect of or fully
                 perform, as the case may be, the Guaranteed Obligations.
                 Further, it shall not be necessary for KCIT, in order to
                 enforce such payment by Guarantor, first to institute suit or
                 pursue or exhaust any rights or remedies against Borrower, PRN
                 or others liable on such indebtedness, or to enforce any
                 rights against any security that shall ever have been given to
                 secure such indebtedness, or to join  Borrower, PRN or any
                 others liable for the payment of the Guaranteed Obligations or
                 any part thereof in any action to enforce this Guaranty, or to
                 resort to any other means of obtaining payment or performance
                 of the Guaranteed Obligations.

         (c)     Suit may be brought or demand may be made against all parties
                 who have signed this Guaranty or any other guaranty covering
                 all or any part of the Guaranteed

   3
                 Obligations, or against any one or more of them, separately or
                 together, without impairing the rights of KCIT against any
                 party hereto.  At any time that KCIT is entitled to exercise
                 its rights or remedies hereunder, it may in its discretion
                 elect to demand payment.

3.       CERTAIN AGREEMENTS AND WAIVERS BY GUARANTOR.

                 nor Guarantor's obligations under the terms of this Guaranty

                 (iv)         whether express or by operation of law, any
                              partial release of the liability of Guarantor

                              right that Guarantor may at any time have against
                              Borrower or PRN whether or not arising in
                              connection with this Guaranty or the Guaranteed
                              Notes (provided, that nothing contained herein
                              shall prevent the assertion of any such claim by
                              separate suit or compulsory counterclaim); or

                 (xii)        the unenforceability of all or any part of the
                              Guaranteed Obligations against Borrower or PRN,
                              whether because the Guaranteed Obligations exceed
                              the amount permitted by law or violate any usury
                              law, or because the act of creating the
                              Guaranteed Obligations, or any part thereof, is
                              ultra vires, or because the officers or persons
                              creating same acted in excess of their authority,
                              or because of a lack of validity or
                              enforceability of or defect or deficiency in the
                              Guaranteed Notes, or because of the subordination
                              of, or moratorium on, payments due and owing
                              under the Guaranteed Notes at such times as the
                              same would otherwise become due and owing under
                              the Guaranteed Notes but for such subordination
                              or moratorium, regardless of the party or
                              parties, including, without limitation, Congress
                              Financial Corporation, intended to be benefited
                              by such subordination or moratorium or because
                              Borrower's or PRN's obligation ceases to exist by
                              operation of law, or because of any other reason
                              or circumstance, it being agreed that Guarantor
                              shall remain liable hereon regardless of whether
                              Borrower, PRN or any other person be found not
                              liable on the Guaranteed Obligations, or any part
                              thereof, for any reason (and regardless of any
                              joinder of Borrower, PRN or any other party in
                              any action to obtain payment of any or all of the
                              Guaranteed Obligations); provided, however, that
                              if any part of the Guaranteed Obligations is not
                              enforceable against Borrower or PRN, as the case
                              may be, because of the proper exercise of any
                              right of set-off against the Guaranteed Notes
                              pursuant to the terms of the Acquisition
                              Agreement, that such part of the Guaranteed
                              Obligations shall not be enforceable against
                              Guarantor.

         (b)     In the event any payment by Borrower, PRN or any other party
                 to KCIT is held to constitute a preference,  fraudulent
                 transfer or other voidable payment under any bankruptcy,
                 insolvency or similar law, or if for any other reason KCIT is
                 required to refund such payment or pay the amount thereof to
                 any other party, such payment by Borrower, PRN or any other
                 party to KCIT shall not constitute a release of Guarantor from
                 any liability hereunder, and this Guaranty shall continue to
                 be effective or shall be reinstated (notwithstanding any prior
                 release or discharge by KCIT of this Guaranty or of
                 Guarantor), as the case may be, with respect to, and this
                 Guaranty shall apply to, any and all amounts so refunded by
                 KCIT or paid by KCIT to another party, together with any
                 interest paid by KCIT and any attorneys' fees, costs and
                 expenses paid or incurred by KCIT in





                                      -5-
   6
                 connection with any such event (all of which amounts shall
                 constitute part of the Guaranteed Obligations).  It is the
                 intent of Guarantor and KCIT that the obligations and
                 liabilities of Guarantor hereunder are absolute and
                 unconditional under any and all circumstances and that until
                 the Guaranteed Obligations are fully and finally paid, and not
                 subject to refund or disgorgement, the obligations and
                 liabilities of Guarantor hereunder shall not be discharged or
                 released, in whole or in part, by any act or occurrence that
                 might, but for the provisions of this Guaranty, be deemed a
                 legal or equitable discharge or release of a guarantor. KCIT
                 shall be entitled to continue to hold this Guaranty in its
                 possession for a period of one year from the date the
                 Guaranteed Obligations are paid and performed in full and for
                 so long thereafter as may be necessary to enforce any
                 obligation of Guarantor hereunder and/or to exercise any right
                 or remedy of KCIT hereunder.

         (c)     If acceleration of the time for payment of any amount payable
                 by Borrower and/or PRN under the Guaranteed Notes is stayed or
                 delayed by any law or tribunal, all such amounts shall
                 nonetheless be payable by Guarantor on demand by KCIT.

4.       OTHER LIABILITY.  If Guarantor becomes liable for any indebtedness
         owing by Borrower or PRN to KCIT other than under this Guaranty, such
         liability shall not be in any manner impaired or affected hereby, and
         the rights of KCIT hereunder shall be cumulative of any and all other
         rights that KCIT may have against Guarantor.  If Borrower or PRN is or
         becomes indebted to KCIT for any indebtedness other than or in excess
         of the Indebtedness for which Guarantor is liable under this Guaranty,
         any payment received or recovery realized upon any indebtedness of
         Borrower or PRN to KCIT may, except to the extent paid by Guarantor on
         the Indebtedness for which Guarantor is liable under this Guaranty or
         specifically required by law or agreement of KCIT to be applied to the
         Indebtedness for which Guarantor is liable under this Guaranty, in
         KCIT's sole discretion, be applied upon indebtedness of Borrower or
         PRN to KCIT other than the Indebtedness for which Guarantor is liable
         under this Guaranty.

5.       KCIT ASSIGNS.  This Guaranty is for the benefit of KCIT and KCIT's
         successors and assigns, and in the event of a permitted assignment of
         the Guaranteed Obligations, or any part thereof, the rights and
         benefits hereunder, to the extent applicable to the Guaranteed
         Obligations so assigned, may be transferred with such Guaranteed
         Obligations. Guarantor waives notice of any transfer or assignment of
         the Guaranteed Obligations, or any part thereof, and agrees that
         failure to give notice will not affect the liabilities of Guarantor
         hereunder.

6.       BINDING EFFECT.  This Guaranty is binding not only on Guarantor, but
         also on Guarantor's successors and assigns.  Words importing persons
         herein shall include firms, associations, partnerships (including
         limited partnerships), joint ventures, trusts,





                                      -6-
   7
         corporations and other legal entities, including public or governmental
         bodies, agencies or instrumentalities, as well as natural persons.

7.       GOVERNING LAW.  This Guaranty, and its validity, enforcement, and
         interpretation, shall for all purposes by governed by and construed in
         accordance with the laws of the State of Delaware and applicable
         United States federal law, and is intended to be performed in
         accordance with, and only to the extent permitted by, such laws.  All
         obligations of Guarantor hereunder are payable and performable at the
         place or places where the Guaranteed Obligations are payable and
         performable.

8.       INVALIDITY OF CERTAIN PROVISIONS.  If any provision of this Guaranty
         or the application thereof to any person or circumstance shall, for
         any reason and to any extent, be judicially declared to be invalid or
         unenforceable, neither the remaining provisions of this Guaranty nor
         the application of such provision to any other Person or circumstance
         shall be affected thereby, and the remaining provisions of this
         Guaranty, or the applicability of such provision to other Persons or
         circumstances, as applicable, shall remain in effect and be
         enforceable to the maximum extent permitted by applicable law.

9.       ATTORNEYS' FEES AND COSTS OF COLLECTION.  Guarantor shall pay on
         demand all reasonable attorneys' fees and all other costs and expenses
         incurred by KCIT in the enforcement of or preservation of KCIT's
         rights under this Guaranty.  Guarantor agrees to pay interest on any
         expenses or other sums due to KCIT under this Section 9 that are not
         paid when due, at a rate per annum equal to the lesser of (i) the
         maximum rate of interest permitted by applicable law, or (ii) the
         Default Rate (as defined in the Guaranteed Notes). Guarantor's
         obligations and liabilities under this Section 9 shall survive any
         payment or discharge in full of the Guaranteed Obligations.

10.      PAYMENTS.  All sums payable under this Guaranty shall be paid in
         lawful money of the United States of America that at the time of
         payment is legal tender for the payment of public and private debts.

11.      CONTROLLING AGREEMENT.  It is not the intention of KCIT or Guarantor
         to obligate Guarantor to pay interest in excess of that lawfully
         permitted to be paid by Guarantor under applicable law.  Should it be
         determined that any portion of the Guaranteed Obligations or any other
         amount payable by Guarantor under this Guaranty constitutes interest
         in excess of the maximum amount of interest that Guarantor, in
         Guarantor's capacity as guarantor, may lawfully be required to pay
         under applicable law, the obligation of Guarantor to pay such interest
         shall automatically be limited to the payment thereof in the maximum
         amount so permitted under applicable law.  The provisions of this
         Section 11 shall override and control all other provisions of this
         Guaranty and of any other agreement between Guarantor and KCIT.

12.      REPRESENTATIONS, WARRANTIES, AND COVENANTS OF GUARANTOR.  Guarantor
         hereby represents, warrants, and covenants that (a) after giving
         effect to this Guaranty,





                                      -7-
   8
         Guarantor is solvent, and does not intend to incur or believe that it
         will incur debts that will be beyond its ability to pay as such debts
         mature; (b) KCIT has no duty at any time to investigate or inform
         Guarantor of the financial or business condition or  affairs of
         Borrower or PRN or any change therein, and Guarantor will keep itself
         fully appraised of Borrower's and PRN's financial and business
         condition; (c) Guarantor acknowledges and agrees that Guarantor may be
         required to pay and perform the Guaranteed Obligations in full without
         assistance or support from Borrower, PRN or any other party; and (d)
         Guarantor has read and fully understand the provisions contained in
         the Guaranteed Notes.  Guarantor's representations, warranties and
         covenants are a material inducement to KCIT to make the Loan and
         accept the Guaranteed Notes and shall survive the execution hereof and
         any bankruptcy, foreclosure, transfer of security or other event
         affecting Borrower, PRN, Guarantor, any other party, or any security
         for all or any part of the Guaranteed Obligations.

13.      NOTICES.  Unless specifically provided otherwise, any notice for
         purposes of this Guaranty or any other document relating hereto shall
         be given in writing or by telex or by facsimile (fax) transmission and
         shall be addressed or delivered to the respective addresses set forth
         in this Guaranty, or to such other address as may have been previously
         designated by the intended recipient by notice given in accordance
         with this Section.  If sent by prepaid, registered or certified mail
         (return receipt requested), the notice shall be deemed effective when
         deposited in a regularly maintained receptacle of the United States
         Postal Service; if transmitted by telex, the notice shall be effective
         when transmitted (answerback confirmed); and if transmitted by
         facsimile or personal delivery, the notice shall be effective when
         received.  No notice of change of address shall be effective except
         upon actual receipt.  This Section 13 shall not be construed in any
         way to affect or impair any waiver of notice or demand provided in
         this Guaranty or in any other Loan Document or to require giving
         notice or demand to or upon any Person in any situation or for any
         reason.

14.      CUMULATIVE RIGHTS.  The exercise of KCIT of any right or remedy
         hereunder or under the Guaranteed Notes, or at law or in equity, shall
         not preclude the concurrent or subsequent exercise of any other right
         or remedy.  KCIT shall have all rights, remedies and recourses
         afforded to KCIT by reason of this Guaranty, the Guaranteed Notes, or
         by law, equity or otherwise, and the same (a) shall be cumulative and
         concurrent, (b) may be pursued separately, successively or
         concurrently against Guarantor or others obligated for the Guaranteed
         Obligations, or any part thereof, or against any one or more of them,
         or against any security or otherwise, at the sole discretion of KCIT,
         (c) may be exercised as often as occasion therefor shall arise, it
         being agreed by Guarantor that the exercise of, discontinuance of the
         exercise of or failure to exercise any of such rights, remedies, or
         recourses shall in no event be construed as a waiver or release
         thereof or of any other right, remedy, or recourse, and (d) are
         intended to be, and shall be, non-exclusive.  No  waiver of any
         default on the part of Guarantor or of any breach of any of the
         provisions of this Guaranty or of any other document shall be
         considered a waiver of any other or subsequent default or breach, and
         no delay or omission in exercising or





                                      -8-
   9
         enforcing the rights and powers granted herein or in any other
         document shall be construed as a waiver of such rights and powers, and
         no exercise or enforcement of any rights or powers hereunder or under
         any other document shall be held to exhaust such rights and powers,
         and every such right and power may be exercised from time to time. The
         granting of any consent, approval or waiver by KCIT shall be limited
         to the specific instance and purpose therefor and shall not constitute
         consent or approval in any other instance or for any other purpose.
         No notice to or demand on Guarantor in any case shall of itself
         entitle Guarantor to any other or further notice or demand in similar
         or other circumstances.  No provision of this Guaranty or any right,
         remedy or recourse of KCIT with respect hereto, or any default or
         breach, can be waived, nor can this Guaranty or Guarantor be released
         or discharged in any way or to any extent, except specifically in each
         case by a writing intended for that purpose (and which refers
         specifically to this Guaranty) executed, and delivered to Guarantor,
         by KCIT.

15.      TERM OF GUARANTY.  This Guaranty shall continue in effect until all
         the Guaranteed Obligations are fully and finally paid, and discharged,
         except that, and notwithstanding any return of this Guaranty to
         Guarantor, this Guaranty shall continue in effect (i) with respect to
         all obligations and liabilities of Guarantor under Section 9 of this
         Guaranty, and (ii) as provided in Section 4(b) hereof.

16.      FURTHER ASSURANCES.  Guarantor at Guarantor's expense will promptly
         execute and deliver to KCIT upon KCIT's request all such other and
         further documents, agreements, and instruments in compliance with or
         accomplishment of the agreements of Guarantor under this Guaranty.

17.      NO FIDUCIARY RELATIONSHIP.  The relationship between KCIT and
         Guarantor is solely that of KCIT and guarantor.  KCIT has no fiduciary
         or other special relationship with or duty to Guarantor and none is
         created hereby.

18.      INTERPRETATION.  The term "KCIT" shall be deemed to include any
         permitted subsequent holder(s) of the Guaranteed Notes.  Whenever the
         context of any provisions hereof shall require it, words in the
         singular shall include the plural, words in the plural shall include
         the singular, and pronouns of any gender shall include the other
         genders.  Captions and headings herein are for convenience only and
         shall not affect the construction of the document.  All references in
         this Guaranty to Schedules, Articles, Sections, Subsections,
         paragraphs and subparagraphs  refer to the respective subdivisions of
         this Guaranty, unless such reference specifically identifies another
         document.  The terms "herein," "hereof," "hereto," "hereunder" and
         similar terms refer to this Guaranty and not to any particular section
         or subsection of this Guaranty.  The terms "include" and "including"
         shall be interpreted as if followed by the words "without limitation."
         All references in this Guaranty to sums denominated in dollars or with
         the symbol "$" refer to the lawful currency of the United States of
         America, unless such reference specifically identifies another

19.      TIME OF ESSENCE.  Time shall be of the essence in this Guaranty with
         respect to all of Guarantor's obligations hereunder.

20.      ENTIRE AGREEMENT.  This Guaranty embodies the entire agreement between
         KCIT and Guarantor with respect to the guaranty by Guarantor of the
         Guaranteed Obligations.  This Guaranty supersedes all prior agreements
         and understandings, if any, with respect to the guaranty by Guarantor
         of the Guaranteed Obligations.  No condition or conditions precedent
         to the effectiveness of this Guaranty exist.  This Guaranty shall be
         effective upon execution by Guarantor and delivery to KCIT.

         IN WITNESS WHEREOF, Guarantor duly executed this Guaranty as of the
30th day of September, 1994.

                                               GUARANTOR:
