investment with the objective of capital appreciation on behalf of AJR, Cambrian

of Mr. Roepers is serving as the president and managing officer of the Reporting
Person.

          Item 3 is hereby restated in its entirety as follows:

          The  Shares  purchased  by the  Reporting  Person  on  behalf  of AJR,
Cambrian  Fund,  the  Managed  Accounts  and the Plan  were  purchased  with the
investment capital of such entities and accounts.  The Shares that may be deemed





to be  beneficially  owned by Mr. Roepers  individually  were purchased with the
personal funds of Mr. Roepers or members of Mr. Roepers'  immediate family.  The
aggregate amount of funds used in making the purchases reported on this Schedule
13D Amendment No. 1 was $4,133,368.


Item 4.   Purpose of Transaction.
          ----------------------

          Item 4 is hereby restated in its entirety as follows:

          The Reporting  Person acquired,  on behalf of AJR,  Cambrian Fund, the
Managed Accounts,  the Plan and Mr. Roepers (including  immediate family members
of Mr. Roepers), and continues to hold, the Shares reported in this Schedule 13D
for  investment   purposes.   The  Reporting  Person  intends  to  evaluate  the
performance  of the Shares as an investment in the ordinary  course of business.
The  Reporting  Person  pursues  an  investment  objective  that  seeks  capital
appreciation.  In pursuing  this  investment  objective,  the  Reporting  Person
analyzes the operations, capital structure and markets of companies in which the
Reporting  Person's clients invest,  including the Issuer, on a continuous basis
through analysis of documentation  and discussions with  knowledgeable  industry
and market observers and with representatives of such companies.

          The Reporting Person will continuously  assess the Issuer's  business,
financial  condition,  results of operations  and  prospects,  general  economic
conditions,  the  securities  markets  in  general  and those for the  Shares in
particular, other developments and other investment opportunities.  Depending on
such  assessments,  the Reporting  Person may acquire  additional  Shares or may
determine  to sell or otherwise  dispose of all or some of the Shares  presently
held by AJR,  Cambrian  Fund,  the Managed  Accounts,  the  Plan and Mr. Roepers
(including  immediate  family  members of Mr. Roepers) in the open market  or in
private  transactions.  Such  actions  will  depend  upon a variety of  factors,
including, without limitation, current and anticipated future trading prices for
the Shares, the financial condition,  results of operations and prospects of the
Issuer, alternative investment opportunities, general economic, financial market
and industry  conditions  and other factors that the  Reporting  Person may deem
material to its investment decision.

          The  Reporting  Person will continue its active  discussions  with the
Issuer's  management  with  respect  to  actions  which  might  be  taken by the
management of the Issuer to maximize  shareholder value of the Issuer.  Attached
is a letter dated August 17, 2006 to the Chairman of the Issuer,  outlining  the





Reporting  Person's  proposal  for a $3  billion  share  repurchase  plan  as an
alternative  to a potential sale of the Issuer to a financial  buyers group.  In
addition, the Reporting Person may hold discussions with other parties who might
engage in shareholder  value enhancing  activities for the benefit of all of the
Issuer's shareholders.  There can be no assurance that the Reporting Person will
take any of the actions described in the previous sentence.

          Except as set forth above,  the Reporting  Person has no present plans
or proposals which relate to or would result in any of the transactions required
to be described in Item 4 of Schedule 13D.


Item 5.   Interest in Securities of the Issuer.
          ------------------------------------

          Item 5 is hereby restated in its entirety as follows:

          (a) Based upon the  information  contained in the  Issuer's  Quarterly
Report on Form 10-Q filed with the Securities and Exchange  Commission on August
8, 2006,  there were issued and  outstanding  216,300,000  Shares as of July 31,
2006.

          (b) The  Reporting  Person  does  not  directly  own any  Shares.  The
Reporting Person has entered into an investment  advisory agreement with each of
AJR,  Cambrian  Fund,  the Managed  Accounts and the Plan  pursuant to which the
Reporting Person has investment authority with respect to the securities held by
such entities or in such  accounts.  Such power includes the power to dispose of
and the power to vote the Shares.  By reason of the  provisions of Rule 13d-3 of
the Securities Exchange Act of 1934, as amended,  the Reporting Person is deemed
to be the beneficial owner of the Shares held by such entities and accounts.  In
addition,  the Reporting  Person has sole  dispositive and voting power over the
4,900  Shares  that  may be  deemed  to be  beneficially  owned  by Mr. Roepers.
Accordingly,  the Reporting  Person is deemed the beneficial owner of 10,837,200
Shares, or 5.0% of the outstanding Shares.

          (c) The  following  table  details the  transactions  by the Reporting
Person,  on behalf of AJR,  Cambrian Fund, the Managed Accounts and the Plan, in
Shares,  as well as transactions in Shares that may be deemed to be beneficially
owned by Mr. Roepers, during the past sixty (60) days:

Person, any entity for which the Reporting Person serves as investment  advisor,

past sixty (60) days.

August 17, 2006


Mr. Stephen M. Wolf
Chairman
R.R. Donnelley & Sons Company
111 South Wacker Drive
Chicago, Illinois 60606

Dear Mr. Wolf:

As you may know, we are one  of R.R. Donnelley's (RRD) largest shareholders with
over 10.8 million  shares and, as such,  we share a keen  interest  with you and
RRD's Board of Directors to maximize RRD's shareholder value over the long term.

In light of recent news  reports  indicating  that a bid by one or more  private
equity groups may be forthcoming,  I am writing you to underscore the importance
of our December 2005 proposal (please see our 13D filing of January 27, 2006 for
details) to engage in a large share  repurchase  program.  Such a program  would
leverage the value of RRD to the company's current shareholders.

To us, the sell-side suggested potential takeover price (mostly ranging from $36
to $40 per share)  would be  unacceptable,  given that you would be handing over
the majority of the potential appreciation for RRD's shareholders to a financial
buyers  group.  You  have  a  fiduciary   responsibility   to  all  current  RRD
shareholders   to  evaluate  all  avenues  for  long  term   shareholder   value
enhancement.  I am sure  that  this is  your and CEO Mark Angelson's  focus  and
intent as well.  However, the potential of one or more (presumably)  unsolicited
bids has accelerated the need for bold and immediate action.

Therefore, we hereby revise our proposal from  December 2005, which called for a
$1 billion  share buy back.  We now urge the Board of Directors to consider a $3
billion  share buy  back  plan, which  should be  implemented  as  promptly  and
cost-effectively  as possible.  The $3 billion share buy back  represents  about
half  the  senior  debt  that a  financial  buyers  group  would  put on the RRD
businesses (we assumed a $40 per share deal with 25% equity, 50% senior debt and
25% high yield debt).

Excessive  concern  over the reaction of debt rating  agencies  (about which the
potential  financial buyers of RRD will not be concerned) and maintaining nearly
unlimited  financial  flexibility  to  make  acquisitions  will  now  have to be
considered  secondary to the  importance  of doing what is right for all current
shareholders of RRD.





Page Two
Letter to Mr. Stephen M. Wolf
August 17, 2006



We urge you to protect  current  shareholders  from losing most of the upside in
their RRD investment to a newly interested financial buyers group,  particularly
those shareholders who have been patient for the past several years, waiting for
an adequate  return on their  investment.  The $3.0 billion buy back plan we are
suggesting  would  retire  about 87 million  RRD shares (or about 40% of current
shares  outstanding)  and increase EPS in 2007 by an  incremental  27% to $3.45.
Please see the attachment for details.

At the midpoint of a previously achieved,  and well-deserved,  P/E multiple in a
range of 12-15x, RRD shares might trade above $46 per share in the next year. In
addition,  we believe  that the post buy back level of debt will still allow the
company  to  maintain  solid  credit  ratings  and  have  sufficient   financial
flexibility for accretive add-on acquisitions.

I trust that you and the Board of  Directors  will make the right  decision  for
shareholders at this crucial juncture in RRD's history.

Sincerely,


/s/ Alexander J. Roepers

Alexander J. Roepers
