                                      of
                           ENTRUST TECHNOLOGIES INC.

No. 1                                                        159,692 Shares

THIS CERTIFIES THAT, for value received, the sufficiency of which is hereby

entitled, on the terms and subject to conditions set forth below, to subscribe
for and purchase from Entrust Technologies Inc., a Maryland corporation (the
"Company"), at the Warrant Price defined in Section 2 below, 159,692 fully paid
and non-assessable shares of the Company's Common Stock (the "Warrant Shares"),
such price and such number of shares being subject to adjustment upon occurrence
of the contingencies set forth in this Warrant.

Upon delivery of this Warrant (with the Notice of Exercise in the form attached
as Attachment A), together with payment of the Warrant Price for the shares of
   ------------
the Company's Common Stock, $.01 par value per share (the "Common Stock"),
thereby purchased, which payment may be made by converting this Warrant, or any
portion thereof, pursuant to Section 3 below ("Warrant Conversion"), at the
principal office of the Company or at such other office or agency as the Company
may designate by notice in writing to the holder hereof, the holder of this
Warrant shall be entitled to receive a certificate or certificates for the
shares of Common Stock so purchased.  All shares of Common Stock which may be
issued upon the exercise of this Warrant will, upon issuance, be fully paid and
non-assessable and free from all taxes, liens and charges with respect thereto.

This Warrant is subject to the following terms and conditions:

     Term of Warrant.  This Warrant may be exercised in whole or in part, at any
     ---------------
time after issuance and prior to 5:00 p.m., PST, April 11, 2003 (the "Term").
Upon the expiration of the Term, this Warrant, to the extent not exercised,
shall terminate.

     Warrant Price.  The exercise price of this Warrant (the "Warrant Price")
     -------------
shall equal $21.92 per share, subject to adjustment as provided in Section 5
below.

     Method of Exercise.
     ------------------
          (i)  Cash Exercise.  The purchase rights represented by this Warrant
               -------------
may be exercised by the Warrantholder, in whole, or in part, by the surrender of
this Warrant (with the duly executed Notice of Exercise attached as Attachment
                                                                    ----------
A) at the principal office of the Company, and by the payment to the Company, by
-
certified or cashier's check or other check acceptable to the Company, of an
amount equal to the aggregate Warrant Price of the Warrant Shares being
purchased.
          (ii) Net Issue Exercise.  In lieu of exercising this Warrant for cash
               ------------------
under clause (i), in the event that the Company's securities are listed on the
Nasdaq National Market, the Warrantholder may elect to receive Warrant Shares
equal to the value of this Warrant (or the portion thereof being canceled) by
surrender of this Warrant at the principal office of the Company and
specification of such election on the Notice of Election, in which event the
Company shall issue to the Warrantholder a number of Warrant Shares computed
using the following formula:

X = Y(A-B)
    ------
      A

Where     X    =    the number of Warrant Shares to be issued to the
                    Warrantholder.
          Y    =    the number of Warrant Shares for which this Warrant is then
                    being exercised.
          A    =    the fair market value of one share of the Company's Common
                    Stock.
          B    =    the Warrant Price (as adjusted to the date of such
                    calculation).

     (iii)     Fair Market Value. For purposes of this Section 3, the fair
               -----------------
               market value of the Company's Common Stock shall mean the average
               of the closing bid and asked prices of the Company's Common Stock
               quoted on the
<PAGE>

               Nasdaq National Market, or the closing prices quoted on any
               exchange on which the Common Stock is listed, whichever is
               applicable, as published in the Western Edition of The Wall
                                                                  --------
     4.        Street Journal for the ten (10) trading days prior to the date of
               --------------
               determination of fair market value.
     5.        Vesting.  This Warrant has vested in full.
               Adjustment of Warrant Price and Number of Warrant Shares.
               The number and kind of Warrant Shares purchasable upon the
               exercise of this Warrant and the Warrant Price shall be subject
               to adjustment from time to time in accordance with the following
               provisions:
       (a)     Reclassification, Consolidation, Merger, etc. In case of any
               --------------------------------------------
               reclassification, exchange, substitution or change of outstanding
               securities of the class issuable upon exercise of this Warrant
               (other than as a result of a subdivision or combination), or in
               case of any consolidation or merger of the Company with or into
               another corporation, or the sale, transfer or lease of all or
               substantially all of the assets of the Company, the Company, or
               such successor corporation, as the case may be, shall execute a
               new Warrant, providing that the holder of this Warrant shall have
               the right to exercise such new Warrant, and procure upon such
               exercise in lieu of each Warrant Share previously issuable upon
               exercise of this Warrant, the kind and amount of shares of stock,
               other securities, money and property receivable upon such
               reclassification, exchange, substitution, change, consolidation,
               merger, sale, transfer or lease by a holder of one Warrant Share
               immediately prior to such event. Such new Warrant shall provide
               for adjustments which shall be as nearly equivalent as may be
               practicable to the adjustments provided for in this Section 5.
               The provisions of this paragraph (a) shall similarly apply to
               successive reclassifications, exchanges, substitutions, changes,
               consolidations, mergers, sales, transfers or leases.
<PAGE>

 (b) [Intentionally omitted]

 (c) Subdivision, Stock Dividend or Combination of Shares. If the Company at any
     ----------------------------------------------------
time while this Warrant remains outstanding and unexpired shall subdivide or
combine the Common Stock, or shall issue a stock dividend with respect to the
Common Stock, the Warrant Price shall be proportionately decreased in the case
of a subdivision or stock dividend or increased in the case of a combination.

 (d) Adjustment of Number of Shares.  Upon each adjustment in the Warrant Price
     ------------------------------
for subdivisions or combinations as contemplated under paragraph (c) above, the
number of shares of Common Stock purchasable hereunder shall be adjusted, to the
nearest whole share, to the product obtained by multiplying the number of shares
purchasable immediately prior to such adjustment in the Warrant Price by a
fraction, the numerator of which shall be the Warrant Price immediately prior to
such adjustment and the denominator of which shall be the Warrant Price
immediately thereafter.

 (e) No Impairment.  The Company shall not, by amendment of its Articles of
     -------------
Incorporation or through a reorganization, transfer of assets, consolidation,
merger, dissolution, issue, or sale of securities or any other voluntary action,
avoid or seek to avoid the observance or performance of any of its terms to be
observed or performed under this Warrant by the Company, but shall at all times
in good faith assist in carrying out of all the provisions of this Section 5 and
in taking all such action as may be necessary or appropriate to protect the
Warrantholder's rights under this Section 5 against impairment.  If the Company
takes any action affecting the Common Stock other than as described above that
adversely affects Warrantholder's rights under this Warrant, the Warrant Price
shall be adjusted downward.

6.   Reservation of Stock. On and after the date hereof, the Company will
     --------------------
reserve from its authorized and unissued Common Stock a sufficient number of
shares to provide for the issuance of the Warrant Shares upon the exercise of
this Warrant.

7.   Notices.
     -------

 (a) Upon any adjustment of the Warrant Price and any increase or decrease in
the number of shares of Common Stock purchasable upon the exercise of this
Warrant, then the Company shall give written notice of such adjustment promptly
thereafter to the registered holder of this Warrant (the "Notice"). The Notice
shall be mailed to the address of such holder as shown on the books of the
Company and shall state the Warrant Price as adjusted and the increased or
decreased number of shares purchasable upon the exercise of this Warrant,
setting forth in reasonable detail the method of calculation of each.

 (b) [Intentionally omitted]

8.   Miscellaneous.
     -------------

 (a) The terms of this Warrant shall be binding upon and shall inure to the
benefit of any successors or assigns of the Company and of any permitted assigns
of the Warrantholder.

 (b) Other than as provided herein, no holder of this Warrant, as such, shall be
entitled to vote or receive dividends or be deemed to be a shareholder of the
Company for any purpose, nor shall anything contained in this Warrant be
construed to confer upon the holder of this Warrant, as such, any rights of a
shareholder of the Company or any right to vote, give or withhold consent to any
corporate action, receive notice of meetings, receive dividends or subscription
rights, or otherwise.

 (c) Receipt of this Warrant by the holder hereof shall constitute acceptance of
and agreement to the foregoing terms and conditions.

 (d) Upon receipt of evidence reasonably satisfactory to the Company of the
loss, theft, destruction or mutilation of this Warrant and, in the case of any
such loss, theft or distribution, upon delivery of an indemnity agreement
reasonably satisfactory in form and amount to the Company or, in the case of any
such mutilation, upon surrender and cancellation of such Warrant, the Company at
its expense will execute and deliver, in lieu thereof, a new Warrant of like
date and tenor.

 (e) Any provision of this Warrant may be amended, waived or modified upon the
written consent of the Company and the holders of a majority of the Warrant
Shares issued or issuable upon exercise of this Warrant or any successor
warrant(s).

 (f) This Warrant shall be governed by the internal substantive laws, but not
the choice of law rules, of the State of California.

SECURITY            :    Common Stock
NUMBER OF SHARES    :
DATE                :    _______________, 200_

In connection with the purchase of the above-listed Securities, the Purchaser
represents to the Company the following:

          (a)  It has substantial experience in evaluating and investing in
private placement transactions of securities in companies similar to the Company
so that it is capable of evaluating the merits and risks of its investment in
the Company and has the capacity to protect its own interests. It acknowledges
that its investment in the Company is highly speculative and entails a
substantial degree of risk and it is in a position to lose the entire amount of
such investment.

          (b)  It is acquiring the Securities for investment for its own
account, not as a nominee or agent, and not with the view to, or for resale in
connection with, any distribution thereof. It understands that the Securities
have not been, and will not be, registered under the Securities Act of 1933, as
amended (the "Securities Act"), by reason of a specific exemption from the
registration provisions of the Securities Act, the availability of which depends
upon, among other things, the bona fide nature of the investment intent and the
                              ---- ----
accuracy of its representations as expressed herein. It is an "accredited
investor" within the meaning of Regulation D, Rule 501(a), promulgated by the
Securities and Exchange Commission (the "SEC").

          (c)  It acknowledges that the Securities must be held indefinitely
unless subsequently registered under the Securities Act or unless an exemption
from such registration is available. It is aware of the provisions of Rule 144
promulgated under the Securities Act which permit limited resale of shares
purchased in a private placement subject to the satisfaction of certain
conditions, including, among other things, the existence of a public market for
the shares, the availability of certain current public information about the
Company, the resale occurring not less than one year after a party has purchased
and paid for the security to be sold, the sale being effected through a
"broker's transaction" or in transactions directly with a "market maker" and the
number of shares being sold during any three-month period not exceeding
specified limitations.

          (d)  [Intentionally omitted]

          (e)  It has had an opportunity to discuss the Company's business,
management and financial affairs with its management. It has also had an
opportunity to ask questions of officers of the Company, which questions were
answered to its satisfaction. It understands that such discussions, as well as
any written information issued by the Company, were intended to describe certain
aspects of the Company's business and prospects but were not a thorough or
exhaustive description. It acknowledges that any business plans prepared by the
Company have been and continue to be subject to change and that any projections
included in such business plans are necessary speculative in nature, and it can
be expected that
<PAGE>

some or all of the assumptions of the projections will not materialize or will
vary significantly from actual results.

          (f)  It understands that the certificates evidencing the Securities
will be imprinted with a legend which prohibits the transfer of the Securities
unless they are registered or such registration is not required in the opinion
of counsel for the Purchaser reasonably satisfactory to the Company or unless
the Company receives a no-action letter from the SEC.

The following legends will be placed on the certificate(s) for the Securities,
or any substitutions therefor:

          THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE BEEN
          ACQUIRED FOR INVESTMENT AND HAVE NOT BEEN REGISTERED
          UNDER THE SECURITIES ACT OF 1933, AS AMENDED.  SUCH
          SECURITIES MAY NOT BE SOLD OR TRANSFERRED IN THE ABSENCE
          OF SUCH REGISTRATION UNLESS THE COMPANY RECEIVES AN
          OPINION OF COUNSEL REASONABLY ACCEPTABLE TO IT STATING
          THAT SUCH SALE OR TRANSFER IS EXEMPT FROM THE
          REGISTRATION AND PROSPECTUS DELIVERY REQUIREMENTS OF
          SUCH ACT.

                            FOURTEENTH AMENDMENT TO
                     DEBTOR-IN-POSSESSION CREDIT AGREEMENT

                         Dated as of November 22, 2000

          Reference is made to that certain Debtor-In-Possession Credit
Agreement dated as of September 13, 1999 (as heretofore amended, supplemented or
otherwise modified, the "DIP Credit Agreement"), by and among Vencor, Inc., a
Delaware corporation ("Vencor"), and Vencor Operating, Inc., a Delaware
corporation ("Vencor Opco"), each as debtor and debtor-in-possession, and each
of Vencor's subsidiaries listed on the signature pages thereof, each as debtor
and debtor-in-possession (each such subsidiary, Vencor and Vencor Opco
individually referred to herein as a "Borrower" and, collectively, on a joint
and several basis, as the "Borrowers"); the Lenders listed on the signature
pages thereof; and Morgan Guaranty Trust Company of New York, as arranger,
collateral agent and administrative agent (in such capacity, "Administrative
Agent") for the Lenders, and as an issuing bank for Letters of Credit
thereunder. Capitalized terms used herein without definition herein shall have
the meanings assigned to such terms in the DIP Credit Agreement.

          The Borrowers have requested that Lenders further extend the deadline
for filing a plan of reorganization acceptable to the Required Lenders in the
Chapter 11 Cases.  Accordingly, Borrowers and the undersigned Lenders hereby
agree that Section 5.10 of the DIP Credit Agreement is hereby amended by
deleting the reference to "November 22, 2000" contained therein and substituting
therefor "December 20, 2000".

          On and after the Amendment Effective Date (as defined below), each
reference in the DIP Credit Agreement to "this Agreement", "hereunder",
"hereof", "herein" or words of like import referring to the DIP Credit
Agreement, and each reference in the other Financing Documents to the "DIP
Credit Agreement", "thereunder", "thereof" or words of like import referring to
the DIP Credit Agreement, shall mean and be a reference to the DIP Credit
Agreement as amended by this Amendment to Debtor-In-Possession Credit Agreement
(this "Amendment"; the DIP Credit Agreement, as so amended, being the "Amended
Agreement").

          Without limiting the generality of the provisions of Section 11.05 of
the DIP Credit Agreement, the amendments set forth in the paragraphs above shall
be limited precisely as written, and nothing in this Amendment shall be deemed
to prejudice any right or remedy that the Administrative Agent or any Lender may
now have or may have in the future under or in connection with the DIP Credit
Agreement or any of such other Financing Documents.  Except as specifically
amended by this Amendment, the DIP Credit Agreement and such other Financing
Documents shall remain in full force and effect and are hereby ratified and
confirmed.

          In order to induce Lenders to enter into this Amendment, each
Borrower, by its execution of a counterpart of this Amendment, represents and
warrants that (a) such Borrower
<PAGE>

has the corporate or other power and authority and all material Governmental
Approvals required to enter into this Amendment and to carry out the
transactions contemplated by, and perform its obligations under, the Amended
Agreement, (b) the execution and delivery of this Amendment and the performance
of the Amended Agreement have been duly authorized by all necessary corporate or
other action on the part of such Borrower, (c) the execution and delivery by
such Borrower of this Amendment and the performance by such Borrower of the
Amended Agreement do not and will not contravene, or constitute a default under,
any Applicable Laws (including an applicable order of the Court) or any
provision of its Organizational Documents, or of any agreement or other
instrument binding upon it or result in or require the imposition of any Liens
(other than the Liens created by the Collateral Documents) on any of its assets,
(d) the execution and delivery by such Borrower of this Amendment and the
performance by such Borrower of the Amended Agreement do not and will not
require any action by or in respect of, or filing with, any governmental body,
agency or official, (e) this Amendment and the Amended Agreement have been duly
executed and delivered by such Borrower and constitute the valid and binding
obligations of such Borrower, enforceable in accordance with their respective
terms, except as may be limited by general principles of equity, (f) for
purposes of the Borrowing Order (i) this Amendment constitutes a non-material
modification of the DIP Credit Agreement and the Financing Documents, and (ii)
notice of this Amendment has been given to and received by counsel to the
Committee (as defined in the Borrowing Order), and (g) after giving effect to
this Amendment, no event has occurred and is continuing or will result from the
consummation of the transactions contemplated by this Amendment that would
constitute a Default.

          This Amendment may be executed in any number of counterparts and by
different parties hereto in separate counterparts, each of which when so
executed and delivered shall be deemed an original, but all such counterparts
together shall constitute but one and the same instrument.  This Amendment shall
become effective (the date of such effectiveness being the "Amendment Effective
Date") upon the earliest date on or prior to November 29, 2000 that (a) the
Borrowers and Required Lenders shall have executed counterparts of this
Amendment and the Borrowers and the Administrative Agent shall have received
written or telephonic notification of such execution and authorization of
delivery thereof; (b) the Administrative Agent shall have received evidence
satisfactory to it that all outstanding statements of O'Melveny & Myers LLP,
Davis Polk & Wardwell and Policano & Manzo that are received by Vencor prior to
12:00 Noon (New York City time) on November 20, 2000 have been paid in full; and
(c) no objections to this Amendment have been served on the Administrative Agent
by the Committee.

          Pursuant to paragraph 3 of the Borrowing Order, this Amendment shall
become effective upon the Amendment Effective Date without the need for any
further order of the Court and upon compliance with the notice requirement of
