agreement, representation or warranty of either of Sellers contained in this

to be furnished by either of Sellers hereunder; and (iii) any suit, action,

                --------------------------
          hold Sellers, and Sellers' affiliates, directors, officers, employees,

          Indemnified Parties"), harmless from and against any and all claims,
          demands, losses, obligations, liabilities (including, without limit,
          attorneys' fees and costs) and any other damages, except consequential
          or indirect damages in excess of $1,000,000, that Sellers' Indemnified
          Parties shall incur or suffer, arising from,

<PAGE>

          related to or in connection with: (i) any misrepresentation, violation
          or breach of any representation, warranty, covenant, or agreement of
          the Buyer in the Purchase Agreement and/or any other of the
          Transaction Documents, certificates or instruments furnished by Buyer;
          and (ii) any suit, cause of action, proceeding, claim, representation,
          pending or threatened, regarding the Assets or Assumed Liabilities as
          of and after the Closing Date (subsections 6.02(i) and (ii) are
          collectively referred to herein as the "Buyer's Obligations").

     (d)  Section 6.03 is hereby deleted in its entirety and replaced with the
following:

          "6.03  Limitation of Right To Indemnification.

          (i)  With respect to this Article VI, any Buyer Indemnified Party or
          Seller Indemnified Party to be indemnified hereunder shall be referred
          to as the "Indemnified Party," and the party obligated to indemnify
          the Indemnified Party is defined as the "Indemnifying Party." No
          Indemnified Party shall be entitled to seek indemnification from the
          Indemnifying Party hereunder unless and until the aggregate amount of
          the Indemnified Parties' claims for indemnification hereunder exceed
          the sum of $25,000.00 (the "Threshold Claim Amount"); provided,
          however, that once the Threshold Claim Amount has been exceeded, any
          Indemnified Party shall be entitled to seek indemnification for the
          full amount of such party's claims, including the Threshold Claim
          Amount; and

          (ii) Notwithstanding the foregoing, the aggregate amount of
          indemnification payments to the Indemnified Parties for which the
          Indemnifying Party may be liable pursuant to this Article shall be
          limited to a total of $4,000,000.00 (the "Maximum Indemnification
          Payment Amount")."

     (e)  The following shall be added as a new Section 6.04:

          "6.04  Indemnification Procedures.  With respect to third-party
                 --------------------------
          claims, all claims for indemnification by any Indemnified Party
          hereunder shall be asserted and resolved as set forth in this Section
          6.04.  In the event that any written claim or demand for which an
          Indemnifying Party would be liable to any Indemnified Party hereunder
          is asserted against or sought to be collected from an Indemnified
          Party by a third party, such Indemnified Party shall promptly, but in
          no event more than thirty (30) days following such Indemnified Party's
          receipt of such claim or demand, notify the Indemnifying Party of such
          claim or demand and the amount or the estimated amount thereof to the
          extent then feasible (which estimate shall not be conclusive of the
          final amount of such claim or demand) ("Claim Notice"); provided,
          however, that the Indemnified Party's failure to

                                       3
<PAGE>

          provide such notice in not more than thirty (30) days shall not
          preclude the Indemnified Party from being indemnified for such claim
          or demand except to the extent that the failure to give timely notice
          results in the forfeiture of substantive defenses by the Indemnifying
          Party. The Indemnifying Party shall have thirty (30) days from the
          personal delivery or mailing of the Claim Notice ("Notice Period") to
          notify the Indemnified Party: (a) whether or not the Indemnifying
          Party disputes the liability of the Indemnifying Party to the
          Indemnified Party hereunder with respect to such claim or demand; and
          (b) whether or not it desires to defend the Indemnified Party against
          such claim or demand. All costs and expenses incurred by the
          Indemnifying Party in defending such claim or demand shall be the
          liability of the Indemnifying Party; provided, however, that the
          amount of such costs and expenses that shall be the liability of the
          Indemnifying Party shall not exceed the Maximum Indemnification
          Payment Amount. Except as hereinafter provided, in the event that the
          Indemnifying Party notifies the Indemnified Party within the Notice
          Period that it desires to defend the Indemnified Party against such
          claim or demand, the Indemnifying Party shall have the right to defend
          the Indemnified Party against such claim or demand by appropriate
          proceedings and shall have the sole power to direct and control such
          defense; provided, however, that to the extent provided by the
          Indemnifying Party's insurer, the selection of counsel shall be done
          with the consent of the Indemnified Party, which consent shall not be
          unreasonably withheld. If any Indemnified Party desires to participate
          in any such defense, it may do so at its sole cost and expense. The
          Indemnified Party shall not settle a claim or demand without the
          consent of the Indemnifying Party. The Indemnifying Party shall not,
          without the prior written consent of the Indemnified Party, settle,
          compromise or offer to settle or compromise any such claim or demand
          on a basis which would result in the imposition of a consent order,
          injunction or decree that would materially restrict the future
          activity or conduct of the Indemnified Party or any subsidiary or
          affiliate thereof. If the Indemnifying Party elects not to defend the
          Indemnified Party against such claim or demand, whether by not giving
          the Indemnified Party timely notice as provided above or otherwise,
          then the amount of any such claim or demand or, if the same be
          contested by the Indemnified Party, then that portion thereof as to
          which such defense is unsuccessful (and the reasonable costs and
          expenses pertaining to such defense), shall be the liability of the
          Indemnifying Party, subject to the limitations set forth in Section
          6.03 of this Agreement. To the extent the Indemnifying Party shall
          direct, control or participate in the defense or settlement of any
          third-party claim or demand, the Indemnified Party will give the
          Indemnifying Party and its counsel, without charge, access to, during
          normal business hours, the relevant business records and any other
          documents, and shall permit them to consult with the employees and
          counsel of the Indemnified Party. The Indemnified Party shall use its
          commercially reasonable best efforts in the defense of all such claims
          or demands. Notwithstanding the foregoing, the Indemnified Party shall
          have the right to employ separate counsel at the Indemnified Party's
          expense and solely to control its own defense of such assessed
          liability; provided the Indemnified Party shall

                                       4
<PAGE>

          not settle or compromise any claim or demand without the consent of
          the Indemnifying Party, such consent not to be unreasonably withheld."

     (f) The following shall be added as a new Section 6.05:

          "Section 6.05  Manner of Indemnification of Indemnified Party.
                         ----------------------------------------------

          the Indemnified Party is any of the Sellers' Indemnified Parties under
          this Article VI shall be effected by delivery of a cashier's check or
          certified check to the Indemnified Party not later than thirty (30)
          days from the earlier of: (i) the date on which the Indemnified Party
          and the Indemnifying Party agree as to the amount of payment for such
          indemnification; or (ii) the date on which a final non-appealable
          arbitration, decision, or order of court of competent jurisdiction is
          issued.

               (b)  Payment for indemnification by the Indemnifying Party, where
          the Indemnified Party is any of the Buyer's Indemnified Parties under
          this Article VI, shall be effected by the utilization of the Escrow
          Fund in accordance with Section 1.07 of the Purchase Agreement and the
          Escrow Agreement."

     (g)  The following shall be added as a new Section 6.06:

                                ---------------

$1,500,000.00                                            Raleigh, North Carolina
                                                               February 13, 2001

     FOR VALUABLE CONSIDERATION, receipt of which is hereby acknowledged, the
undersigned, Tangram Enterprise Solutions Inc., a Pennsylvania corporation
("Maker"), hereby agrees to pay to Axial Technology Holding AG, a Swiss
registered company, or order ("Payee"), the principal sum of One Million Five
Hundred Thousand Dollars ($1,500,000.00), without interest thereon.  Unless
stated otherwise in this Note, all sums owing hereunder must be paid in lawful
money of the United States of America. This Note is given in connection with
that certain Asset Purchase Agreement dated February 13, 2001, as amended by the
First Addendum to the Asset Purchase Agreement dated as of February 13, 2001 by
and among Maker, Payee and Wyzdom Solutions Inc., a California corporation.

     Maker shall pay Payee the aggregate amount of $1,500,000.00, without
offset, payable in three installments as follows: (1) $300,000.00 on February
13, 2002; (2) $500,000.00 on February 13, 2003; and (3) $700,000.00 on February
13, 2004.  In the event that any installment is not paid within ten (10) days
after the date such installment is due, Maker agrees to pay the installment
amount together with a late charge equal to the interest thereon from the due
date of such installment until paid in full at the rate of twelve percent (12%)
per annum, compounded monthly; provided that interest hereunder shall not exceed
the maximum rate allowed by law.  Privilege is reserved of Maker paying this
Note in full or in part at any time prior to any installment date without
penalty.

     If Maker shall (a) fail to pay when due any sums payable hereunder; or (b)
file a petition for bankruptcy, make a general assignment for the benefit of
creditors, or apply for the appointment of a receiver, trustee, or custodian,
then Payee may, in its sole discretion, declare all sums owing under this Note
immediately due and payable; provided, however, that if any document related to
this Note provides for automatic acceleration of payment of sums owing
hereunder, all sums owing hereunder shall be automatically due and payable in
accordance with the terms of that document.

records, Maker furnishes Payee with a written objection to such statement
specifying the error or errors contained in such statement.
