March 6, 1998

To the Board of Directors of Echlin Inc.:

I  am  writing  to  you  in  your  capacity  as  fiduciaries  for  Echlin's
shareholders.  Echlin appears to be pursuing extreme defensive tactics that
violate the principles of good corporate governance and which could destroy
substantial  value for Echlin  shareholders - and the shareholders of every
other company incorporated in Connecticut.

Indeed,  since  the  day the  Wall  Street  Journal  first  reported  on an
Echlin-instigated  attempt to change Connecticut law to curtail shareholder
voting  rights,  more than $200  million  of value has been  destroyed  for
Echlin shareholders. No other state has ever enacted such a draconian "dead
hand" provision into law, promising  Connecticut lasting national nororiety
for abusive corporate governance.

Do you  realize  what this  unprecedented  bill  would do?  Even if 100% of
Echlin  shareholders  voted to remove directors,  they could not be removed
for a year.  After a year,  even if a new board were elected by 100% of the
shareholders, the new Board could not approve a business combination - even
one all shareholders wanted. Only the old Board - the directors unanimously
voted out by the shareholders - would be able to approve it for five years.

I can't  believe you or  Connecticut  lawmakers  intended  such an abuse of
corporate democracy.

This  is  especially  misguided  because  the  vast  majority  of  Echlin's
Connecticut  jobs are not at risk.  As you know,  less than 3% of  Echlin's
30,000 employees are in Connecticut.  Most of these Connecticut jobs are in
the Branford  manufacturing  facility  which SPX has publicly  committed to
continue  operating.  We have also committed to continue Echlin's community
involvement and charitable  contributions  at least at current  levels.  We
have  pledged  to  maintain a  significant  Connecticut  presence,  explore
expansion  opportunities  in the State,  and evaluate  alternatives for the
Branford  headquarters.  Accordingly,  the Connecticut jobs in question are
approximately 115 corporate  positions at headquarters.  Thus, it should be
quite clear that the issue of Connecticut jobs is a red herring.

Let me also address some misconceptions  contained in Echlin's  preliminary
revocation solicitation materials.

Echlin's  materials  question  whether  SPX has made a  serious,  bona fide
offer. It is simply untrue that, "All SPX has done is to float a proposal."
Let me assure you that SPX is fully committed to acquiring Echlin,  and, as
we stated in our own SEC filings,  we will start our exchange offer as soon
as permitted under the federal  securities laws. Let me remind you that, on
February 17, 1998, SPX delivered a proposed  merger  agreement to you which
SPX was, and still is, prepared to enter into with Echlin. SPX has invested
more  than $43  million  in Echlin  shares - giving  us a larger  ownership
position in Echlin than your entire Board and management  combined - and we
have incurred substantial expenses in connection with our proposal.

In  addition,  SPX has today begun to solicit  written  demands from Echlin
shareholders to call a special  meeting,  after having completed SEC review
of its solicitation materials.

Echlin's  materials  question the business rationale for the combination of
Echlin and SPX,  they  express  doubt  about  SPX's  ability to realize the
anticipated  savings,  and they assert that SPX is  attempting  to purchase
Echlin at a price which does not reflect its true worth.  Our  response has
not changed since we communicated with Echlin last year: meet with us; hear
us out on the  rationale  for  the  transaction  and  its  benefits  to all
constituencies; show us that there is more value inherent in Echlin.

We  recognize  that the  conventional  reaction  to an  unsolicited  merger
proposal is: knee-jerk rejection, a search for a white knight, criticism of
the unsolicited bidder and its motives, and attempts to get self-interested
legislation enacted. You should recognize that the transaction that we have
proposed  is  not an  80's-style  attempt  to  make a  quick  buck.  On the
contrary,  we are not  raiders;  we are serious  business  people who run a
business  similar to Echlin's and who believe that the  combination  of the
two companies is  compelling - and would benefit both sets of  shareholders
as well as all other  constituencies  involved.  Any  concerns you may have
regarding the impact of the  transaction on your  shareholders,  creditors,
employees,  customers,  suppliers  and  communities  can be  addressed.  We
believe SPX is the ideal merger partner for Echlin.

In keeping with your  fiduciary  duty,  we urge you to negotiate  with us a
combination that is clearly in Echlin's best interests.  Let me repeat that
our strong  preference  is to complete  this  transaction  on a  negotiated
basis.  While  we  believe  we have  made a full and  fair  offer  based on
publicly available information, we are prepared to recognize any additional
value Echlin can  substantiate in the context of a negotiated  transaction.
We are also prepared to consider  issues  relating to other  constituencies
you may identify to us. We are ready to meet  immediately with you and your
advisors to quickly complete this compelling transaction.

If you  negotiate  with  us,  we hope to  persuade  you that we  should  be
Echlin's white knight.

Very truly yours,

SPX CORPORATION
