Pursuant  to  Section  9.5  of  the  Loandata  LLC  Operating   Agreement   (the
"Agreement"),  Section 3.7.1 of the Agreement (as heretofore  amended) is hereby
amended and restated to read in its entirety as follows:



                      3.7.1.  At any time prior to the date on which the Company
        has received an aggregate of $7,500,000 in Capital  Contributions (other
        than by way of  contributions  in the form of property) and capital from
        the funding of the Vaults as contemplated in Section 3.9.1 (except prior
        to the End of Offer  Period  relating  to an Offer  Notice  pursuant  to
        Section  3.7.2,  during the pendency of a Third Party Offer  pursuant to
        Section 3.7.3, or prior to the End of New Offer Period relating to a New
        Offer Notice pursuant to Section 3.7.4, in any of which cases the rights
        of the Class A Member to make  additional  Capital  Contributions  under
        this Section 3.7 shall be governed by the provisions of Sections  3.7.2,
        3.7.3 or 3.7.4,  as the case may be),  and  subject to the provision set
        forth in the last  sentence of this  Section  3.7.1,  the Class A Member
        may, in its sole  discretion,  by written notice to the Company elect to
        make additional  Capital  Contributions  to the Company on the terms set
        forth in this  Section  3.7.1.  Until the dates  indicated,  the Class A
        Member may acquire the following additional  Percentage Interests in the
        Company pursuant to this Section 3.7.1 (or lesser  Percentage  Interests
        on a proportionate basis for lesser Capital Contributions) by making the
        additional  Capital  Contribution  set  forth  opposite  the  respective
        Percentage Interests (with prior Capital  Contributions from all Members
        after  the  initial  Capital  Contributions  made as of the date of this
        Agreement and all capital received by the Company through the funding of
        the  Vaults  as   contemplated  in  Section  3.9.1  treated  as  Capital
        Contributions solely for purposes of valuing the New Interest):

               $1,500,000    an additional 21.868% July 31, 1998
               $2,250,000    an additional 11.765% October 31, 1998
               $3,150,000    an additional  6.666% January 31, 1999;

        provided,  however,  that the Class A Member may not make an  additional
        Capital  Contribution  pursuant to this Section  3.7.1 after the date on
        which the Company has received an aggregate of $2,100,000 before October
        27, 1998 (or $4,350,000 afterwards) in Capital Contributions (other than
        by way of  contributions  in the form of property)  and capital from the
        funding  of the Vaults as  contemplated  in Section  3.9.1  without  the
        consent of a majority of the Board of Managers,  which majority includes
        at least one member who is not designated by the Class A Member.

        Notwithstanding  anything  to the  contrary  in  this  Agreement,  it is
        anticipated  that the  Class A Member  may  loan  the  Company  money or
        provide  services or property  to the  Company,  at the Class A Member's
        option (in addition to its capital  contribution  of  $1,500,000 in July
        1998)  and this  loan  will be  evidenced  by a note or  notes  from the
        Company.  If on or before September 30, 1998 the Company has not entered
        into a definitive agreement with an investor to make an investment of at
        least  $1,000,000 at a valuation  equal to or greater than the valuation
        step then in effect under this  section  3.7.1 and if (i) any portion of
        the loan remains  outstanding  and unpaid on September 30, 1998; or (ii)
        any investor has agreed in writing to make an  investment in the Company
        at a valuation or terms less favorable to the Company than the valuation
        step then in effect under this  section  3.7.1;  or (iii)  approved by a
        majority of the Board of Managers,  which majority includes at least one
        member  who is not  designated  by the Class A  Member,  then all or any
        portion of the outstanding loan (including  accrued interest) may at the
        option of the Class A Member be converted on or before  January 31, 1999
        to equity at a rate of 7.144% per $250,000.



This amendment  restatement  supersedes  all other  amendments to this Agreement
which are dated before the effectiveness of this Amendment.



In all other  respects  the  Agreement  shall  remain in full  force and  effect
without alteration. Effective as of the 17th day of July 1998.
