Re:               Going Private Transaction
- --------------------------------------------------------------------------------

As you may be aware,  on July 28, 2005, we entered into a merger  agreement with
Insight Acquisition Corp., a corporation  organized by affiliates of The Carlyle
Group for the sole purpose of effecting the merger and related transactions. The
transaction  would  have the  effect  of  taking  Insight  private  through  the
acquisition of all of the outstanding publicly-held shares of Insight.

Consummation  of the transaction is subject to stockholder  approval  (including
approval  by a  majority  of the  disinterested  public  stockholders)  and  the
satisfaction  of a number  of other  legal  requirements,  including  rules  and
regulations  issued by the Securities and Exchange  Commission.  If the proposed
transaction is consummated, the currently outstanding shares of Insight's common
stock,  other than certain shares held by certain  continuing  investors,  would
receive a cash payment equal to $11.75 per share.

Insight's  records  indicate that you presently own the Insight equity set forth
on the  attached  Statement  of  Equity  Holdings.  If you  believe  any of this
information  is  incorrect,   please  contact  Gerald  Isaacs,  Human  Resources
Coordinator,  as soon as possible.  Attached to the Statement of Equity Holdings
are  appendices  that  describe  the  treatment  of your equity  holdings in the
proposed transaction. Certain of these documents also contain brief descriptions
of certain federal income tax  consequences  associated  with the  going-private
proposal.  Of  course,  tax  consequences  may vary  depending  upon  individual
circumstances  and these  materials  are not  intended  to provide  you with tax
advice.  Accordingly,  we urge you to consult  with your  personal  tax  adviser
regarding  your own federal  income tax  consequences,  as well as any state and
local tax consequences.

If the  transaction  is not approved by the  stockholders  or does not otherwise
close,  Insight  would  continue  operating as a public  company and your equity
holdings would be unaffected.

THIS  MEMORANDUM IS NOT A SOLICITATION  OF A PROXY OR A SUBSTITUTE FOR ANY PROXY
STATEMENT OR OTHER  FILINGS THAT WILL BE MADE WITH THE  SECURITIES  AND EXCHANGE
COMMISSION  ("SEC").  YOU ARE URGED TO THOROUGHLY REVIEW AND CONSIDER  INSIGHT'S
PRELIMINARY PROXY STATEMENT FILED WITH THE SEC AND ANY OTHER MATERIAL RELATED TO
THE  TRANSACTION  WHEN  FILED  WITH THE SEC  BECAUSE  THEY DO AND  WILL  CONTAIN
IMPORTANT INFORMATION. ANY SUCH DOCUMENTS, ONCE FILED, WILL BE AVAILABLE FREE OF
CHARGE AT THE SEC'S WEBSITE  (WWW.SEC.GOV) AND FROM INSIGHT.  YOU SHOULD NOT PUT
UNDUE RELIANCE ON THE  PRELIMINARY  PROXY  STATEMENT,  AS IT IS NOT COMPLETE AND
REMAINS SUBJECT TO REVIEW BY THE SEC AND INSIGHT AND CHANGES MAY BE SUBSTANTIAL.

                              STOCK OPTION APPENDIX

A.   VESTED "IN THE MONEY" STOCK OPTIONS  (I.E.,  OPTIONS WITH AN EXERCISE PRICE
     LOWER THAN THE PRICE TO BE PAID FOR INSIGHT SHARES IN THE MERGER)

Upon the consummation of the merger, these options would be canceled in exchange
for the right to receive a cash payment per option share equal to the difference
between the  exercise  price and the $11.75 per share  merger  price.  This cash
payment would be taxable to you as ordinary income.

B.   "OUT OF THE MONEY" OPTIONS  (I.E.,  OPTIONS WITH AN EXERCISE PRICE EQUAL TO
     OR HIGHER THAN THE PRICE TO BE PAID FOR INSIGHT SHARES IN THE MERGER)

Upon the  consummation  of the merger,  you would  receive no cash  payments for
these options and they would be canceled. You would not recognize any tax on the
cancellation of your underwater options.

Of course,  tax consequences may vary depending on individual  circumstances and
these materials are not intended to provide you with tax advice. Accordingly, we
urge you to consult  your own personal  tax advisor  regarding  your own federal
income tax consequences, as well as any state and local tax consequences.




                                 401(K) APPENDIX


Upon  consummation of the merger,  you may continue to participate in the 401(k)
plan. If you currently hold Insight stock in your 401(k) account,  including any
fractional shares,  these shares would be cashed out in the merger at the merger
price. That transaction would be tax deferred. You will also receive information
regarding the reinvestment of the cash proceeds received into your account.
