                                                            Wayne, Pennsylvania
                                                                  June 18, 1996
$1,000,000

     FOR VALUED RECEIVED, Tangram Enterprise Solutions, Inc., a Pennsylvania
corporation (the "Borrower"), having an office at 5511 Capital Center Drive,
Suite 400, Raleigh, North Carolina 27606, hereby promises to pay to the order
of Safeguard Scientifics (Delaware), Inc., a Delaware corporation (the
"Lender"), at the Lender's office located at 435 Devon Park Drive, Wayne,
Pennsylvania 19087 or at such other place in the continental United States as
the Lender may designate in writing, upon demand, in lawful money of the United
States, and in immediately available funds, the principal sum of up to One
Million and no/100 Dollars ($1,000,000), or so much thereof as shall have been
advanced by the Lender to the Borrower as hereinafter set forth and then be
outstanding, and to pay interest thereon monthly in arrears on the first
business day of each calendar month at an annual rate equal to the announced
prime rate of Midlantic Bank, N.A. of Philadelphia, Pennsylvania (the "Prime
Rate") plus one percent (1%). All amounts advanced hereon, but not to exceed
$1,000,000 at any one time outstanding in the aggregate, shall be so advanced
upon the request of the Borrower. All amounts so advanced hereon and all
payments made on account of the principal hereof shall be recorded in the books
of the Lender, which records shall be final and binding, but failure to do so
shall not release the Borrower from any of its obligations hereunder.

     Borrower's obligations under this Note, regardless of whether demand for
payment has been made by Lender, are subject and subordinate to all of
Borrower's obligations to Wachovia Bank of North Carolina, N.A. ("Wachovia
Bank"), and all liens and security interests granted by Borrower to Wachovia
Bank. Upon the occurrence of an event of default by Borrower and Wachovia Bank,
Borrower shall immediately notify Lender, regardless of whether demand for
payment has been made by Lender, and Lender shall not exercise any of its rights
or remedies against Borrower, and Borrower shall not make any payments to Lender
hereunder, for a period of 90 days thereafter without the consent of Wachovia
Bank so long as there is no uncured event of default outstanding under any
Wachovia Bank loan, Borrower may make all required payments to Lender under this
Note.

     The unpaid principal balance of the Note shall be paid on the date which
is one year and one month after the date of demand for payment by the Lender;
provided that, in the event of a sale of substantially all of the assets of
Borrower, a merger or consolidation of Borrower with or into a third party, or
the acquisition of a majority of Borrower's outstanding voting stock by a
"person" (as such term is defined under Section 13 of the Securities Exchange
Act of 1934, as amended) other than Safeguard Scientifics, Inc. or any of its
wholly-owned subsidiaries, the unpaid principal balance of the Note shall be
paid on the date which is five days after the date of demand for payment by the
Lender.
     All payments made on this Note (including, without limitation, prepayments)
shall be applied, at the option of the Lender, first to late charges and
collection costs, if any, then to accrued interest and then to principal.
Interest payable hereunder shall be calculated for actual days elapsed on the
basis of a 360-day year. Accrued and unpaid interest shall be due and payable
upon maturity of this Note. After maturity or in the event of default, interest
shall continue to accrue on the Note at the rate set forth above and shall be
payable on demand of the Lender.

     Unless there is an uncured event of default under any Wachovia Bank loan,
the outstanding principal amount of this Note may be prepaid by the Borrower


                                       1
<PAGE>


upon notice to the Lender in whole at any time or in part from time to time
without any prepayment penalty or premium; provided, that upon such payment
any interest due to the date of such prepayment on such prepaid amount shall
also be paid.

     Notwithstanding anything in this Note, the interest rate charged hereon
shall not exceed the maximum rate allowable by applicable law. If any stated
interest rate herein exceeds the maximum allowable rate, then the interest
rate shall be reduced to the maximum allowable rate, and any excess payment
of interest made by the Borrower at any time shall be applied to the unpaid
balance of any outstanding principal of this Note.

     An event of default hereunder shall consist of:

       (i) a default in the payment by the Borrower to the Lender of principal
  or interest under this Note as and when the same shall become due and payable;

      (ii) an event of default by the Borrower under any other obligation,
  instrument, note or agreement for borrowed money, beyond any applicable notice
  and/or grace period;

     (iii) institution of any proceeding by or against the Borrower under any
  present or future bankruptcy or insolvency statute or similar law and, if
  involuntary, if the same are not stayed or dismissed within sixty (60) days,
  or the Borrower's assignment for the benefit of creditors or the appointment
  of a receiver, trustee, conservator or other judicial representative for the
  Borrower or the Borrower's property or the Borrower's being adjudicated a
  bankrupt or insolvent.

Upon the occurrence of any event of default, interest shall accrue on the
outstanding balance of this Note at the Prime Rate plus three percent (3%), the
entire unpaid principal amount of this Note and all unpaid interest accrued
thereon shall, at the sole option of the Lender, without notice, become
immediately due and payable, and the Lender shall thereupon have all the rights
and remedies provided hereunder or now or hereafter at law or in equity.

     Any action, suit or proceeding where the amount in controversy as to at
least one party, exclusive of interest and costs, exceeds $1,000,000 ("Summary
Proceeding"), arising out of or relating to this Agreement, or the breach,
termination or validity thereof, shall be litigated exclusively in the Superior
Court of the State of Delaware (the "Delaware Superior Court") as a summary
proceeding pursuant to Rules 124-131 of the Delaware Superior Court, or any
successor rules (the "Summary Proceeding Rules"). Each of the parties hereto
hereby irrevocably and unconditionally (i) submits to the jurisdiction of the
Delaware Superior Court for any Summary Proceeding, (ii) agrees not to commence
any Summary Proceeding except in the Delaware Superior Court, (iii) waives, and
agrees not to plead or to make, any objection to the venue of any Summary
Proceeding in the Delaware Superior Court, (iv) waives, and agrees not to plead
or to make, any claim that any Summary Proceeding brought in the Delaware
Proceeding brought in the Delaware Superior Court has been brought in an
improper or otherwise inconvenient forum, (v) waives, and agrees not to plead
or to make, any claim that the Delaware Superior Court lacks personal
jurisdiction over it, (vi) waives its right to remove any Summary Proceeding to
the federal courts except where such courts are vested with sole and exclusive
jurisdiction by statute and (vii) understands and agrees that it shall not seek
a jury trial or punitive damages in any Summary Proceeding based upon or arising
out of or otherwise related to this Agreement waives any and all rights to any
such jury trial or to seek punitive damages.

     In the event any action, suit or proceeding where the amount in controversy
as to at least one party, exclusive of interest and costs, does not exceed
$1,000,000 (a "Proceeding"), arising out of or relating to this Agreement or the
breach, termination or validity thereof is brought, the parties to such
Proceeding agree to make application to the Delaware Superior Court to proceed


                                       2

under the Summary Proceeding Rules. Until such time as such application is
rejected, such Proceeding shall be treated as a Summary Proceeding and all of
the foregoing provisions of this Section relating to Summary Proceedings shall
apply to such Proceeding.

     If a Summary Proceeding is not available to resolve any dispute hereunder,
the controversy or claim shall be settled by the arbitration conducted on a
confidential basis, under the U.S. Arbitration Act, if applicable, and the
then current Commercial Arbitration Rules of the American Arbitration
Association (the "Association") strictly in accordance with the terms of this
Agreement and the substantive law of the State of Delaware. The arbitration
shall be conducted at the Association's regional office located closest to the
Borrower's principal place of business by three arbitrators, at least one of
whom shall be knowledgeable in software design, programming and implementation
and one of whom shall be an attorney. Judgment upon the arbitrators' award may
be entered and enforced in any court of competent jurisdiction. Neither party
shall institute a proceeding hereunder unless at least 60 days prior thereto
such party shall have given written notice to the other party of its intent to
do so.

     Neither party shall be precluded hereby from securing equitable remedies in
courts of any jurisdiction, including, but not limited to, temporary restraining
orders and preliminary injunctions to protect its rights and interests but shall
not be sought as a means to avoid or stay arbitration or Summary Proceedings.

     The Borrower hereby waives presentment, demand, protest and notice of
dishonor and protest, and also waives all other exemptions; and agrees that
extension or extensions of the time of payment of this Note or any installment
or part thereof may be made before, at or after maturity by agreement by the
Lender. Upon default hereunder the Lender shall have the right to offset the
amount owed by the Borrower against any amounts owed by the Lender in any
capacity to the Borrower, whether or not due, and the Lender shall be deemed to
have exercised such right to offset and to have made a charge against any such
account or amounts immediately upon the occurrence of an event of default
hereunder even though such charge is made or entered on the books of the Lender
subsequent thereto. The Borrower shall pay to the Lender, upon demand, all costs
and expenses, including, without limitation, attorneys' fees and legal expenses,
that may be incurred by the Lender in connection with the enforcement of this
Note.

     Notices required to be given hereunder shall be deemed validly given (i)
three business days after sent, postage prepaid, by certified mail, return
receipt requested, (ii) one business day after sent, charges paid by the sender,
by Federal Express Next Day Delivery or other guaranteed delivery service, (iii)
when sent by facsimile transmission, or (iv) when delivered by hand.:
