Joseph Alsop, CEO of Progress Software Corporation, sent the following email to
eXcelon employees on November 5, 2002.


To:       Everyone at eXcelon Worldwide

From:     Joseph Alsop

Date:     5 November 2002

Subject:  Update on eXcelon-PSC Business Integration Plan

It has been about two weeks since we announced our agreement to combine eXcelon
and Progress Software Corporation (PSC).

We have formed a matrix of integration planning teams made up of leaders in both
companies that are looking at all aspects of the business integration effort.
Regular meetings are already occurring in areas such as engineering, sales,
information technology, and so forth. As many of you will be asked for input to
the planning process, I thank you in advance for your commitment to our mutual
success. Conversely, if you feel you have input that may be important to the
process, please don't wait to be asked. Contact one of the following integration
team ("I-Team") leaders as soon as possible:

The response to our announcement from analysts and press has been very positive.
For example, Gartner Group analyst Roy Schulte was quoted in the publication
Line56 saying, "The eXcelon acquisition brings that company's Stylus Studio,
extensible information server (XIS) and business process management (BPM)
components to bear... Sonic's ESB [Enterprise Service Bus] twist is a lighter,
simpler version of what classic integration brokers offer... It's at a fraction
of the price, it's simpler and in some cases easier to implement."

And AMR wrote: "With the advent of XML-based Web services, companies will also
see more advantages to using a database and a range of tools designed
specifically to support XML and a service-oriented architecture... And Sonic
gains deeper integration capabilities as well as the development tools and
database to get it out of the scenario of competing just for integration
business. Overall, the two should make a good play for a Web services
infrastructure bundle."

We concur. The product synergies and market opportunities of our combined
companies are compelling. Check out the FAQ posted on eXcelon's intranet and on
the PSC investor relations website at:

http://media.corporate-
- -----------------------
ir.net/media_files/nsd/prgs/faq_3.pdf
- -------------------------------------

for the strategic directions driving this merger.

So far, integration planning has involved research and meeting people on both
sides. Over the next few weeks we hope to start establishing more specific
plans. We also have been busy preparing the SEC filings necessary to gain
approval by the SEC and eXcelon stockholders, which are prerequisites to
closing. On Monday eXcelon filed the preliminary stockholder proxy for review by
the SEC and we continue to believe we are on track to close sometime around the
end of the calendar year.



I know many of you have specific questions about what will take place and when.
You may wonder if there will be room for you in the combined organization. Where
will you work? What will it be like working for the Progress Company (tPC) or
Sonic Software?

As you can imagine, there are many things to sort out here. Our primary goals
are to ensure a solid and sustainable business around the object database
products, accelerate growth of Sonic from synergies with eXcelon's XML products,
and create a work environment that will allow us to capture other upside
opportunities from this merger.

We cannot yet say how many people will be affected by staff reductions, but it
is our desire to retain as many as possible to meet our business goals, which
also include a commitment to sell, support, and continue developing all key
eXcelon products. In making decisions, we are looking at the talent pool of the
combined organizations as a whole to obtain the top talent we need to be
successful moving forward.

At the time of the merger all eXcelon employees will become employees of one of
the business units of PSC. Roughly speaking, about half will become part of the
Progress Company, and most of the rest part of Sonic Software. Most employees
will move to the PSC facility nearest to their present eXcelon office location
within a few weeks of the merger.

eXcelon employees that become PSC employees (whether they join Sonic, or the
Progress Company, or one of the other organizations within PSC) will be eligible
for all the same benefits, programs, job opportunities, and other privileges as
available to other PSC employees. Also, your years of service with eXcelon will
be credited toward PSC seniority with respect to benefits programs.

Please take time to read the "HR FAQ" that follows at the bottom of this e-mail,
which may help answer additional questions about working for PSC. I trust that
you'll find PSC to be a vibrant and stimulating atmosphere with lots of
potential for growth. If you have additional questions about any of our HR
programs, please contact Joe Andrews, VP of Human Resources at PSC, as indicated
above.



Regarding eXcelon customers, I am aware that many have been asking about the
future of eXcelon products and what they can expect from PSC. Please look for a
joint letter that Joe Bellini and I plan to send directly to each customer,
explaining our intent to continue support for eXcelon products and to build
long-term business relationships with them. Should you have the opportunity to
convey this message directly to customers and prospects, please do so.

We will do our best to keep you informed within the limits of our need to
continue as separate companies for now. Please stay tuned, and thank you for
whatever you can contribute to the integration planning effort.

Excitement for this merger is definitely building here at PSC. We hope you feel
it too.


Joe Alsop
CEO Progress Software



******************************************
.................................................................................

Human Resources FAQ for eXcelon Employees:

1.   Will all employees be hired by Progress Software Corporation (PSC)?

     At this point in time PSC and eXcelon are reviewing business plans and have
     not finalized the organizational structure. Therefore, headcount
     requirements have not been determined. As a result of the consolidation and
     the possibility of having redundant positions within the two companies we
     do expect that there will be a reduction in force.

2.   Will eXcelon employees have to apply for jobs and be interviewed for
     positions at PSC?

     You will not have to formally apply for positions created within PSC as a
     result of this acquisition. The integration leaders from both companies
     will be making staffing decisions based on the relative skill sets required
     to meet the new business plans.



3.   When will we become PSC employees?

     Once all of the regulatory and stockholder approvals have been secured and
     the acquisition has officially closed, eXcelon employees will become
     employees of PSC. We expect this to occur in the second half of December or
     in January.

4.   How many employees are there at PSC overall?

     Currently there are over 1300 employees worldwide in PSC; Sonic has just
     over 100; the Progress Company has just over 1000; the balance are in
     PeerDirect and corporate organizations.

5.   What kind of career path and opportunities for growth will there be for me
     at PSC?

     Once the final approval of the acquisition is granted, eXcelon employees
     who continue with PSC after the acquisition will share the same
     opportunities as current PSC employees.

6.   Is PSC secure enough to offer increased opportunities in future?

     PSC has been in business for over 20 years, a public company since 1991,
     and consistently profitable with no debt and significant cash reserves.
     We've shown year over year revenue growth over the last 5 quarters and
     profit growth for the last three quarters. PSC is committed to growth in
     both revenue and profit in the markets we serve, and we believe combining
     forces with eXcelon will accelerate our growth strategies.

7.   Will my pay or compensation plan change?

     It is PSC's general intention not to negatively impact the compensation of
     those employees who remain with PSC. However, after the business model is
     finalized, a competitive market analysis will be completed and appropriate
     compensation packages will be developed and communicated to employees.

8.   Will my manager change?



     Once the business plans have been finalized and the organizational
     structure has been determined, we will be in a better position to identify
     the management team. As a result, it's possible your manager may change.

9.   What will happen to my eXcelon options? Will I receive PSC options?

     Once all approvals have been obtained and the acquisition is completed, all
     options to purchase shares of eXcelon common stock for less than $3.19 per
     share will be cashed in for the difference between the exercise price and
     $3.19 per share; options with exercise prices above $3.19 per share will
     have no value.

     eXcelon employees who become PSC employees shall be eligible for the same
     equity programs as other PSC employees. Included is the potential for
     option grants for key employees and eligibility to participate in the
     Employee Stock Purchase Plan.

10.  What will happen to our benefits package?

     PSC offers a complete benefits package for its employees. eXcelon employees
     who transfer to PSC will be eligible to participate in all PSC's benefit
     plans as applicable to your locale. In the US, highlights of our benefit
     package include:

     -   A comprehensive medical and dental plan with doctor and prescription
         drug copays very similar to what is offered with the eXcelon medical
         plan. For calendar year 2002, PSC pays 90% of the monthly premium for
         Individual only coverage and 83% of the Family monthly premium. These
         percentages are subject to change in future plan years.

     -   A 401(k) plan managed through Fidelity with a discretionary company
         match based on attaining corporate financial goals and subject to
         service requirements.

     -   Income protection coverage with short term and long term disability and
         employee life insurance all paid by the Company; optional life
         insurance available for employee, spouse, and dependent children.



     -   Flexible spending reimbursement accounts to reimburse you for certain
         health, dental and adoption expenses.

     -   An innovative Employee Stock Purchase Plan where employees can purchase
         PSC stock at a 15% discount with an extended offering period of 27
         months (versus 6 months typically), to maximize the potential for
         gains.

     -   Time off policies allowing for employee flexibility - includes a
         competitive vacation package and holiday pay. Our vacation accrues as
         follows: Up to 5 years = 15 days/annually, 5 through 9 years = 18
         days/annually, 10+ years = 21 days/annually. At any point in time, you
         can have a vacation balance up to your annual accrual. Holiday Pay
         accrues at 11 total holidays per year: currently 6 company designated,
         5 employee designated.

     Complete details of PSC' benefit package and costs will be provided as we
     move closer to the actual close. Employees transferring to PSC will retain
     their service date, which will apply to appropriate benefit programs.

11.  What will the company culture be like? (e.g. dress code, flex time,
     formality)

     PSC has an open and entrepreneurial culture where we value employee
     contributions and successes. Our values focus on leadership in the market,
     strong financial performance, partner and customer focus, employee
     professional growth and honesty and integrity. We have no formal dress code
     and casual attire is welcomed. Flex time practices are left to the managers
     of individual departments.

12.  What can we expect over the next several weeks? How will we learn the
     details of PSC as they unfold?

     We must all make sure we stay focused on continuing to provide outstanding
     service to our customers. eXcelon will continue to operate independently
     until eXcelon stockholders approve the acquisition and the transaction is
     closed. We must stay focused so as to prevent a let down in service during
     this interim time frame.



     During the interim, integration teams will be meeting regularly to develop
     business and action plans for going forward. We will continue to ask you
     for information, which is critical to ensuring that we build a solid future
     and we encourage you to ask the same type of questions of any one of the
     PSC Leadership Team members.

     As the teams start to build concrete strategic plans, the PSC and eXcelon
     leadership teams will provide you with updated information. We expect that
     some decisions and business practices will evolve and shift with time. This
     evolution is very common in business integrations such as ours and we aim
     to communicate frequently throughout this process.

13.  What should we do if we have questions we would like answered?

     Please don't hesitate to seek answers to questions you have. You should
     address questions to your direct supervisor and in the event that he/she
     doesn't have the answers, questions can be directed to the PSC/eXcelon
     Integration Managers who have been named in other communications.

     It is important to communicate questions and concerns during this time of
     transition. The PSC/ Sonic/ tPC management team is committed to being as
     responsive as possible to your information needs. You can also contact Joe
     Alsop (jwa@progress.com), CEO of Progress Software, Greg O'Connor
     (oconnor@sonicsoftware.com), President of Sonic Software, or Dave Ireland
     (direland@progress.com), President of the Progress Company, with any
     questions you may have.

14.  Where can I find out more information on PSC?

     You can visit PSC's website at www.progress.com to get more information. In
     addition, you can pose questions to representatives of PSC/Sonic/tPC, some
     of who will be present at your office on multiple occasions. We will be
     either meeting with you or emailing you every two weeks with updates.
