Ladies and Gentlemen:

          The undersigned, a shareholder of Teltech Resource Network
Corporation, a Minnesota corporation ("Teltech"), hereby enters into this
Agreement pursuant to Section 8.3(i) of the Agreement and Plan of Merger and
Reorganization dated as of January 21, 2000, pursuant to which Teltech will
merge (the "Merger") with and into a wholly owned subsidiary of Sopheon PLC, a
United Kingdom public company limited by shares ("Sopheon"). The undersigned
will receive shares of common stock of Sopheon ("Sopheon Shares") in connection
with the Merger and agrees with and represents to Sopheon as follows:

          1.   The undersigned is the holder of and is entitled to vote
               ___________ shares of the outstanding common stock and ______
               shares of the outstanding preferred stock of Teltech. Such
               shares, together with any other voting shares of Teltech acquired
               by the undersigned after signing this Agreement and before the
               effective time of the Merger are referred to herein as the
               "Teltech Shares". The undersigned does not own any other voting
               shares of Teltech.

          2.   Except with respect to the exchange of Teltech Shares for Sopheon
               Shares pursuant to the Merger, the undersigned has no current
               plan or intention to engage in any sale of any Teltech Shares
               (whether or not acquired pursuant to the exercise of a stock
               option) on, or prior to, the Merger. The undersigned will
               immediately notify Sopheon and Teltech in writing via facsimile
               of any sale of Teltech Shares by the undersigned on, or prior to,
               the Merger.

          3.   From the date of this Agreement until the effective time of the
               Merger, the undersigned will not purchase, sell, exchange,
               transfer, pledge or otherwise trade in Sopheon stock or rights to
               purchase or sell Sopheon stock. The undersigned understands and
               agrees that this prohibition against trading in Sopheon stock is
               a requirement of the Dutch Securities and Exchange Commission and
               the regulatory bodies of the London Stock Exchange.

          4.   The undersigned will not, without prior written consent of
               Sopheon, sell, transfer or otherwise dispose of, or agree to
               sell, transfer or otherwise dispose of any Sopheon Shares owned
               by the undersigned, or sell or grant options, rights or warrants
               with respect to any Sopheon Shares for a period of 365 days after
               the effective date of the Merger, other than by gifts to donees
               who agree to be bound by the same restriction, or by will or the
               laws of descent.

          5.   The undersigned will not sell, transfer or otherwise dispose of
               any Sopheon Shares other than through a broker specified by
               Sopheon or only after full consultation with such broker.

          6.   This Agreement shall be enforceable by, and shall inure to the
               benefit of and be binding upon, Sopheon and the undersigned and
               their respective successors and assigns. With respect to the
               undersigned, the term "successors and assigns" includes heirs,
               executors, administrators, trustees and successor trustees, and
               personal and other representatives. This Agreement shall be
               governed by and construed, interpreted, and enforced in
               accordance with the laws of the State of Minnesota, without
               regard to the conflicts of law provisions thereof.
