[Microtest Letterhead]                               [Fluke Networks Letterhead]

                      Q&A for Microtest Independent Reps

                Re: The Merger of Microtest and Fluke Networks


1.  Will we be able to sell the Fluke Networks (FNET) products?  Nothing will
    change in the immediate future until the Microtest shareholders and
    government agencies approve the deal. Going forward, it is important that
    everyone understand that this is a merger of two successful companies.
    Consequently, our first step would be to evaluate both companies' channels
    and territories and determine how best to use the resources at our disposal.
    But again, no change in sales responsibilities will happen until the deal is
    approved and this evaluation can be conducted.

2.  Will we be terminated in favor of the direct or indirect FNET sales
    channels?  As stated above, our goal is to use the best mix of resources in
    each territory. Therefore, we want to carefully evaluate both the Microtest
                                                             ----
    and the FNET channels to determine what kind and quantity of sales assets we
    need to meet the customer demand based on our new, expanded product
    offering. It is conceivable that we may need even more resources in a given
    territory than are there today for both companies. Therefore, no change in
    sales responsibilities will happen until that evaluation can be conducted.
    Needless to say, it is in everyone's best interest to keep selling
    aggressively!

3.  Will our contract be modified in any way?  Of course it's premature to
    discuss contracts until the sale is approved, and part of our evaluation in
    the meantime will include current channel contracts. Just as a side note, we
    have found that the philosophies of both Microtest and FNET are very similar
    in this area.

4.  Will any of the current Microtest products be discontinued?  There are
    currently no plans to discontinue any of the cable test products of either
    company.

5.  Will the Phoenix location be "shut down"?  There are no plans to close the
    Phoenix facility. The acquisition was based on the value FNET saw in the
    Microtest organization - its engineering, sales, marketing, support and
    brand resources. Fluke Networks has a track record of leaving successful
    operations where they originally resided: Colorado Springs, Dallas, Austin,
    Boston, and, now, Phoenix.

6.  Will we still "report" to the current Microtest regional organization?
    There is no change in reporting relationship while the deal is being
    approved. In the event the deal is approved, and after our complete channel
    evaluation, we will make those kinds of determinations.

7.  What do I tell my current and prospective customers?  It's business as
    usual. For the time being, they will see no change in sales and support from
    either Fluke Networks or Microtest. Eventually, they will get the benefit of
    dealing with the best aspects of the two leading cable and network test
    companies.


8.  What do I tell my distribution contacts? How will they be notified and what
    will they be told?  It is important to note that most of our fulfillment
    channels are basically the same. We are communicating with the distributors
    immediately informing them of the intent to merge, and will get in contact
    as soon as it's appropriate after the approval period. In the meantime, we
    are urging them to continue business as usual.

9.  What do I do if a customer is considering FNET products versus Microtest?
    Until the transaction closes pending approval of Microtest shareholders and
    government agencies, it's business as usual.
