IBM PUBLIC LICENSE VERSION 1.0 - SECURE MAILER

THE ACCOMPANYING PROGRAM IS PROVIDED UNDER THE TERMS OF THIS IBM PUBLIC

LICENSE ("AGREEMENT").  ANY USE, REPRODUCTION OR DISTRIBUTION OF THE

PROGRAM CONSTITUTES RECIPIENT'S ACCEPTANCE OF THIS AGREEMENT.

1.  DEFINITIONS

"Contribution" means:  

    a) in the case of International Business Machines Corporation ("IBM"), 

       the Original Program, and 

    b) in the case of each Contributor, 

       i)  changes to the Program, and

       ii) additions to the Program;

           where such changes and/or additions to the Program originate

           from and are distributed by that particular Contributor.  

           A Contribution 'originates' from a Contributor if it was added 

           to the Program by such Contributor itself or anyone acting on 

           such Contributor's behalf.  

    Contributions do not include additions to the Program which:

       (i)  are separate modules of software distributed in conjunction 

            with the Program under their own license agreement, and 

       (ii) are not derivative works of the Program.

"Contributor" means IBM and any other entity that distributes the Program.

"Licensed Patents " mean patent claims licensable by a Contributor which

are necessarily infringed by the use or sale of its Contribution alone

or when combined with the Program.

"Original Program" means the original version of the software accompanying

this Agreement as released by IBM, including source code, object code

and documentation, if any.

"Program" means the Original Program and Contributions.

"Recipient" means anyone who receives the Program under this Agreement, 

including all Contributors.

2.  GRANT OF RIGHTS

    a) Subject to the terms of this Agreement, each Contributor hereby

    grants Recipient a non-exclusive, worldwide, royalty-free copyright

    license to reproduce, prepare derivative works of, publicly display,

    publicly perform, distribute and sublicense the Contribution of such

    Contributor, if any, and such derivative works, in source code and

    object code form.

    b) Subject to the terms of this Agreement, each Contributor hereby

    grants Recipient a non-exclusive, worldwide, royalty-free patent

    license under Licensed Patents to make, use, sell, offer to sell,

    import and otherwise transfer the Contribution of such Contributor,

    if any, in source code and object code form.  This patent license

    shall apply to the combination of the Contribution and the Program

    if, at the time the Contribution is added by the Contributor, such

    addition of the Contribution causes such combination to be covered

    by the Licensed Patents.  The patent license shall not apply to any

    other combinations which include the Contribution.  No hardware per

    se is licensed hereunder.

    c) Recipient understands that although each Contributor grants the

    licenses to its Contributions set forth herein, no assurances are

    provided by any Contributor that the Program does not infringe the

    patent or other intellectual property rights of any other entity.

    Each Contributor disclaims any liability to Recipient for claims

    brought by any other entity based on infringement of intellectual

    property rights or otherwise.  As a condition to exercising the rights

    and licenses granted hereunder, each Recipient hereby assumes sole

    responsibility to secure any other intellectual property rights

    needed, if any.  For example, if a third party patent license

    is required to allow Recipient to distribute the Program, it is

    Recipient's responsibility to acquire that license before distributing

    the Program.

    d) Each Contributor represents that to its knowledge it has sufficient

    copyright rights in its Contribution, if any, to grant the copyright

    license set forth in this Agreement.

3.  REQUIREMENTS

A Contributor may choose to distribute the Program in object code form 

under its own license agreement, provided that:

    a) it complies with the terms and conditions of this Agreement; and

    b) its license agreement:

       i)   effectively disclaims on behalf of all Contributors all

            warranties and conditions, express and implied, including

            warranties or conditions of title and non-infringement, and

            implied warranties or conditions of merchantability and fitness

            for a particular purpose;

       ii)  effectively excludes on behalf of all Contributors all 

            liability for damages, including direct, indirect, special, 

            incidental and consequential damages, such as lost profits; 

       iii) states that any provisions which differ from this Agreement 

            are offered by that Contributor alone and not by any other 

            party; and

       iv)  states that source code for the Program is available from 

            such Contributor, and informs licensees how to obtain it in a 

            reasonable manner on or through a medium customarily used for 

            software exchange. 

When the Program is made available in source code form:

    a) it must be made available under this Agreement; and 

    b) a copy of this Agreement must be included with each copy of the 

       Program.  

Each Contributor must include the following in a conspicuous location 

in the Program: 

    Copyright (c) 1997,1998,1999, International Business Machines

    Corporation and others. All Rights Reserved.

In addition, each Contributor must identify itself as the originator of

its Contribution, if any, in a manner that reasonably allows subsequent

Recipients to identify the originator of the Contribution. 

4.  COMMERCIAL DISTRIBUTION

Commercial distributors of software may accept certain responsibilities

with respect to end users, business partners and the like.  While this

license is intended to facilitate the commercial use of the Program, the

Contributor who includes the Program in a commercial product offering

should do so in a manner which does not create potential liability for

other Contributors.   Therefore, if a Contributor includes the Program in

a commercial product offering, such Contributor ("Commercial Contributor")

hereby agrees to defend and indemnify every other Contributor

("Indemnified Contributor") against any losses, damages and costs

(collectively "Losses") arising from claims, lawsuits and other legal

actions brought by a third party against the Indemnified Contributor to

the extent caused by the acts or omissions of such Commercial Contributor

in connection with its distribution of the Program in a commercial

product offering.  The obligations in this section do not apply to any

claims or Losses relating to any actual or alleged intellectual property

infringement.  In order to qualify, an Indemnified Contributor must:

    a) promptly notify the Commercial Contributor in writing of such claim,

and 

    b) allow the Commercial Contributor to control, and cooperate with

       the Commercial Contributor in, the defense and any related 

       settlement negotiations.  The Indemnified Contributor may 

       participate in any such claim at its own expense.

For example, a Contributor might include the Program in a commercial

product offering, Product X.  That Contributor is then a Commercial

Contributor.  If that Commercial Contributor then makes performance

claims, or offers warranties related to Product X, those performance

claims and warranties are such Commercial Contributor's responsibility

alone.  Under this section, the Commercial Contributor would have to

defend claims against the other Contributors related to those performance

claims and warranties, and if a court requires any other Contributor to

pay any damages as a result, the Commercial Contributor must pay those

damages.

5.  NO WARRANTY

EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, THE PROGRAM IS PROVIDED

ON AN "AS IS" BASIS, WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, EITHER

EXPRESS OR IMPLIED INCLUDING, WITHOUT LIMITATION, ANY WARRANTIES OR

CONDITIONS OF TITLE, NON-INFRINGEMENT, MERCHANTABILITY OR FITNESS FOR A

PARTICULAR PURPOSE. Each Recipient is solely responsible for determining

the appropriateness of using and distributing the Program and assumes

all risks associated with its exercise of rights under this Agreement,

including but not limited to the risks and costs of program errors,

compliance with applicable laws, damage to or loss of data, programs or

equipment, and unavailability or interruption of operations. 

6.  DISCLAIMER OF LIABILITY

EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, NEITHER RECIPIENT NOR

ANY CONTRIBUTORS SHALL HAVE ANY LIABILITY FOR ANY DIRECT, INDIRECT,

INCIDENTAL, SPECIAL, EXEMPLARY, OR CONSEQUENTIAL DAMAGES (INCLUDING

WITHOUT LIMITATION LOST PROFITS), HOWEVER CAUSED AND ON ANY THEORY OF

LIABILITY, WHETHER IN CONTRACT, STRICT LIABILITY, OR TORT (INCLUDING

NEGLIGENCE OR OTHERWISE) ARISING IN ANY WAY OUT OF THE USE OR DISTRIBUTION

OF THE PROGRAM OR THE EXERCISE OF ANY RIGHTS GRANTED HEREUNDER, EVEN IF

ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

7.  GENERAL

If any provision of this Agreement is invalid or unenforceable under

applicable law, it shall not affect the validity or enforceability of

the remainder of the terms of this Agreement, and without further action

by the parties hereto, such provision shall be reformed to the minimum

extent necessary to make such provision valid and enforceable.

If Recipient institutes patent litigation against a Contributor with

respect to a patent applicable to software (including a cross-claim or

counterclaim in a lawsuit), then any patent licenses granted by that

Contributor to such Recipient under this Agreement shall terminate

as of the date such litigation is filed.  In addition, If Recipient

institutes patent litigation against any entity (including a cross-claim

or counterclaim in a lawsuit) alleging that the Program itself (excluding

combinations of the Program with other software or hardware) infringes

such Recipient's patent(s), then such Recipient's rights granted under

Section 2(b) shall terminate as of the date such litigation is filed.

All Recipient's rights under this Agreement shall terminate if it fails

to comply with any of the material terms or conditions of this Agreement

and does not cure such failure in a reasonable period of time after

becoming aware of such noncompliance.  If all Recipient's rights under

this Agreement terminate, Recipient agrees to cease use and distribution

of the Program as soon as reasonably practicable.  However, Recipient's

obligations under this Agreement and any licenses granted by Recipient

relating to the Program shall continue and survive. 

IBM may publish new versions (including revisions) of this Agreement

from time to time.  Each new version of the Agreement will be given a

distinguishing version number.  The Program (including Contributions)

may always be distributed subject to the version of the Agreement under

which it was received. In addition, after a new version of the Agreement

is published, Contributor may elect to distribute the Program (including

its Contributions) under the new version. No one other than IBM has the

right to modify this Agreement.  Except as expressly stated in Sections

2(a) and 2(b) above, Recipient receives no rights or licenses to the

intellectual property of any Contributor under this Agreement, whether

expressly, by implication, estoppel or otherwise.  All rights in the

Program not expressly granted under this Agreement are reserved.

This Agreement is governed by the laws of the State of New York and the

intellectual property laws of the United States of America. No party to

this Agreement will bring a legal action under this Agreement more than

one year after the cause of action arose.  Each party waives its rights

to a jury trial in any resulting litigation.
