May 27, 1997

Dear Fellow Stockholder,

         As a follow-up to our May 19, 1997 letter,  we want to provide you with
additional   information  regarding  Gary  D.  Engle  and  the  PLM  Stockholder
Committee. We also want to identify the specific statements and accusations made
by Mr. Engle in information he has distributed which we believe are misleading.

                           PLM'S "NET INCOME" FIGURES

         In our prior  letter,  we  objected to Engle's  statement  that PLM has
incurred  nearly $22.7 million of  cumulative  net losses since 1991. We believe
this  statement  is  inaccurate  because  it does not point out that the  losses
included  dividends of approximately  $21.4 million on preferred stock which has
now been  retired and $5.1 million  resulting  from a  non-recurring  accounting
change. We do, however,  acknowledge that Engle's statement is accurate in to so
far as it  reflects  the  Company's  net income to common  shares for these five
years.

WE DOUBT ENGLE'S CHARACTERIZATION OF HIMSELF AS A "CONCERNED STOCKHOLDER" WHO IS
                         LOOKING OUT FOR YOUR INTEREST.

         In our prior letter, we noted that Engle and companies he controls have
sponsored  21  unsolicited  tender  offers  for  companies  that  he  originally
organized and managed, and have been sued in a federal class action lawsuit, and
in  Massachusetts  Superior  court,  for  breach of his duties to  investors  in
connection with those tender offers.

         Ultimately,  these lawsuits were settled. In the Settlement  Agreement,
without admitting or denying fault,  Engle agreed to disseminate a Supplement to
the Offers  providing  additional  information  to each of the  unitholders,  to
increase the tender offer prices to reflect a premium, and to purchase up 35% of
the outstanding units in the partnerships.

       WE QUESTION ENGLE'S CLAIM THAT "A SALE OF THE COMPANY TO EQUIS ...
                     WOULD BE ATTRACTIVE TO STOCKHOLDERS."

         As  noted  in our  prior  letter  and  press  releases,  shortly  after
submitting his proposals and commencing  this proxy contest,  Engle  delivered a
letter to your Board of Directors  stating  that another  company he controls is
"prepared to offer" to pay  stockholders  $5 per share for all of the  Company's
outstanding  stock.  Engle's proposed  purchase price is below the Company's per
share book  value and below the  market  price as of the close of trading on May
16, 1997. However, a $5.00 price does represent a premium to stock prices before
Engle's  submission  of his  proposed  transaction,  stockholder  proposals  and
nominees  for election to the Board,  and over the historic  price levels of the
past five years.

         Although your Board has decided not to pursue the $5 proposal submitted
by Engle,  it is  committed  to  maximizing  stockholder  value and has  engaged
Josephthal  Lyon & Ross  Incorporated  to assist  the Board in its review of all
financial and strategic  alternatives which fully reflect the Company's inherent
value.

WE DON'T  BELIEVE  ENGLE'S  PROMISE TO INCREASE THE VALUE OF YOUR  INVESTMENT IN
                                      PLM.

         Engle's  past  record  shows a history  of making  below-market  tender
offers for  companies  and  liquidating  them for his own profit.  In one of the
unsolicited tender offers referred to above,  Engle's investment earned a return
of 138% in just eleven  months.  Investors in the same  company  earned 0.6% per
year over approximately 8 years! Indeed,  Engle's proxy materials reveal that he
is already  cashing in -- during the stock's recent price  increase,  Gary Engle
SOLD 31,500 shares of PLM's common stock.

         In our prior  letter,  we noted  that in 13 of the  unsolicited  tender
offers referred to above,  Engle  liquidated the companies  within one year even
though in documents filed with the Securities and Exchange  Commission he stated
that there were no plans to liquidate the companies or sell their assets. We are
concerned that these past actions cast doubt on Mr. Engle's intentions regarding
PLM, not only in the context of a proposed  "cash-out  merger" or tender  offer,
but also in conjunction with his contest for representation on the Board.

        WE DO BELIEVE THAT ENGLE IS ATTEMPTING TO PROFIT AT YOUR EXPENSE

         We do believe that Engle and his  associates  are trying to do the same
thing to PLM's  investors as they have done to other  companies'  investors.  As
part of their attempt to gain control of your Company,  Engle and his associates
submitted five proposals for your  consideration  which would make it easier for
him to succeed in a coercive takeover. They are also sponsoring two nominees for
election to your Board of Directors.

         We  also  think  it is  important  to set  PLM  International's  record
straight.

ENGLE'S STOCK PERFORMANCE GRAPHS ARE MISLEADING.

ENGLE SAYS:           "The poor  performance  of the  Company's  stock is
                      underscored by comparing its significant  decline with the
                      tremendous increase in the major stock market indices ..."

THE TRUTH  IS:        Since  completing  its  restructuring  plan in
                      December 1994,  PLM's stock price has almost doubled,  and
                      it  has  increased  60%  this  year  alone.1  During  both
                      periods, PLM's stock price outperformed the S&P 500 (SPX).
                      Engle's  information  distorts PLM's stock  performance by
                      presenting  different  scales in his two charts.  As shown
                      below,  the  comparative   results  since  completing  our
                      restructuring  appear  much  different  when  PLM's  stock
                      performance is measured on charts using the same scale.

                        [INSERT STOCK PERFORMANCE GRAPH]

The diagram is a line graph showing the percentage change in daily closing price
through  5/16/97 for PLM and the S&P 500. During the defined time period the PLM
line stays generally  above the S&P 500 line (a greater  increase in value since
12/1/94)  until May 1996, and then after lagging behind the S&P 500 for about 11
months, catches and exceeds it in April 1997.

In 1994,  the Board  initiated a share  repurchase  program,  believing that the
Company's  stock price did not fully reflect the intrinsic  value of the shares.
The Board of Directors believes that this program, which to date has resulted in
the  repurchase  of a total  of  approximately  3,500,000  shares  (representing
approximately  22% of the  outstanding  shares) at an average price of $3.60 per
share, has had a positive impact on the increase in the stock price reflected on
the preceding graph. The Company has also experienced nine consecutive  quarters
of profitable operations since completing its restructuring plan.

                     DON'T GAMBLE YOUR INVESTMENT ON ENGLE

We have rebuilt PLM International into a financially sound, growth company.  The
Board  of  Directors  believes  that  it is  not  in the  best  interest  of all
stockholders to turn over control of the Company just when the positive  results
of our strategic plan are beginning to become apparent.
