  Tessera Highlights Significant Progress on Plan to Deliver Value to
  Stockholders

 Says Starboard agenda disruptive, lacks understanding of the IP business and
  not in the interests of Tessera stockholders; Cites failed track record at
                          competitor Unwired Planet

Business Wire

SAN JOSE, Calif. -- April 25, 2013

Tessera Technologies, Inc. (NASDAQ:TSRA) ("Tessera" or the "Company") today
issued and will mail a letter to stockholders highlighting the substantial
steps underway to drive performance, strengthen its financial profile, and
create value for the Company’s stockholders both in the near and long term.
The letter also details the Company’s concerns that the election of Starboard
Value LP’s (“Starboard”) director nominees could quickly destroy stockholder
value and disrupt the significant progress that the Company has made.

The current board and management team have taken significant steps to position
Tessera to deliver meaningful stockholder value, including key governance,
operational and managerial changes. Since August 2012, the leadership team has
aggressively taken actions that include:

  *Halted DigitalOptics Corporation’s (“DOC”) vertical manufacturing efforts
    and refocused its strategy on the differentiated MEMS-related technologies
    – projecting to reduce DOC operating expenses by nearly 40% exiting 2013,
    compared to 2012;
  *Implemented actions to reduce corporate overhead by 38% from 2012 levels
    by the end of 2013;
  *Reconstituted the Board with expanded breadth of directly relevant skills;
    and
  *Strengthened corporate governance.

The Company is acutely aware that there is more work to be done, and
stockholders should feel confident the leadership team remains focused on
continuing to execute its new strategic plan. This plan includes long-term
growth for Tessera’s Intellectual Property (“IP”) segment through new
customers, Invensas technology and selective acquisitions of patent
portfolios. For DOC, the strategic plan is focused on unlocking stockholder
value by shifting to a less cash-and capital-intensive path to bring DOC’s
transformational MEMS auto-focus technology to the mobile market more quickly.

Additionally, the letter from interim chief executive officer (“CEO”) and
executive chairman Richard S. Hill highlights a number of aspects of
Starboard’s campaign to replace the majority of the board of directors that
should give stockholders pause, including the failure to disclose to Tessera
stockholders troubling allegations of conflicts of interest and violations of
professional ethics rules that have been raised regarding one of Starboard's
nominees.

“The restructured Board includes the right mix of independent and new
directors to oversee the continued execution of our strategy and position
Tessera for sustainable growth and profitability. We believe that electing the
Starboard slate would put stockholder value at serious risk by installing
underqualified and conflicted director nominees seeking to implement a flawed
agenda and disrupt a strategy that is gaining momentum,” stated Hill.

The letter further states that “Starboard has launched a proxy fight to take
control of Tessera without paying a premium and without any concrete details
of a new plan or a management team that will drive increased stockholder
value. Importantly, Peter Feld has a history of problematic actions that raise
questions about his true agenda.” The letter also advises that “At best, the
few suggestions Starboard has made are actions that we have already
implemented or announced and, at worst, reflect a complete lack of
understanding of our business.”

Text of April 25 letter from Mr. Hill to Tessera stockholders:

Dear Tessera Stockholders:

On May 23^rd, at our Annual Meeting of Stockholders, you will be presented
with an important choice about your investment and the future path of Tessera
Technologies, Inc. (“Tessera” or the “Company”).

The current board and management team have taken significant steps to position
Tessera to deliver meaningful stockholder value. The leadership team has
aggressively reduced costs and capital spending within DigitalOptics
Corporation (“DOC”); restructured DOC’s supply chain model and manufacturing
objectives and significantly simplified the product portfolio; cut corporate
overhead; enhanced the Board composition and strengthened corporate
governance. We are acutely aware that there is more work to be done and remain
focused on executing our strategic plan and realizing our long-term
objectives. Moreover, we believe it is imperative that we all remain intently
focused on getting the business on the right track, and we believe Starboard’s
actions would undermine our progress at this critical time at Tessera.

TESSERA HAS THE RIGHT BOARD IN PLACE

Recent and dramatic enhancements to the Board ensure that we have the right
team with the critical skills to oversee execution of our strategy:

  *We have added five new independent directors since August 2012 and I was
    appointed as non-executive chairman in March 2013;
  *Each of our nominees has deep financial, operational, engineering, sales
    and/or board level experience at companies that specialize in introducing
    complex technologies into the market;
  *Nearly all of our nominees have CEO or CFO-level experience at companies
    other than Tessera; and
  *Each of our nominees is independent, with the lone recent exception
    arising from my appointment as interim CEO and executive chairman in April
    2013.

Moreover, the directors are as unhappy as you about the Company’s recent
financial performance. However, with the help of our strong new team and after
making some tough decisions, we have begun demonstrating significant progress
that will deliver higher value to stockholders.

TESSERA HAS THE RIGHT MANAGEMENT AND STRATEGIC PLANS

Since August 2012, the Board has driven a number of strategic changes to
improve financial performance and generate returns to our stockholders.
Specifically, we:

  *Assembled a best-in-class management team by appointing new presidents for
    our two business units, Intellectual Property (“IP”) and DOC;
  *Announced the signing of eight-year licenses with SK hynix for both our
    existing IP portfolio and for the first time, our Invensas portfolio in
    January 2013; we expect similarly structured agreements to occur with
    Micron and Samsung in the future;
  *Scored a major litigation win against Amkor with a favorable ruling in
    February 2013 – over $130 million of cash expected over the next few
    years.
  *Announced initial cost cutting measures of $15-18 million within DOC in
    November 2012;
  *Halted DOC’s vertical manufacturing efforts and refocused its strategy on
    the differentiated MEMS-related technologies – projecting to reduce DOC
    operating expenses by nearly 40%, excluding costs of revenues, to an
    annual run rate of approximately $53 million exiting 2013, compared to $88
    million spent in 2012; and
  *Implemented actions to reduce corporate overhead by 38% from 2012 levels
    by the end of 2013.

The markets are paying attention and recognizing our progress. Since we began
to implement Board-approved changes in August 2012, the Company’s stock has
risen by nearly 30%, while our peer group has only risen by approximately 6%.

Going forward, we have set near-term and longer-term objectives for our core
business units, as well as financial targets for 2016. Our strategic plan
includes long-term growth for our IP business through new customers, Invensas
technology and selective acquisitions of patent portfolios. For DOC, our
strategic plan is focused on unlocking stockholder value by shifting to a less
cash- and capital-intensive path to bring DOC’s transformational MEMS
auto-focus technology to the mobile market more quickly. The changes we
announced in March 2013 are critical to rapidly achieving the quality and
yield in high-volume manufacturing necessary to deliver profitable,
high-performance products. We expect to invest an additional $50 million
maximum in net spend this year to achieve several deliverables, including the
development of the 8 MP mems | cam^TM product for commercialization.

In short, Tessera has the right plan to deliver value to our stockholders over
the near and long term: continue to reduce costs, manage capital spending
carefully, and adjust our strategic plan as conditions warrant to ensure
attractive returns on our investments. The restructured Board includes the
right mix of independent and highly experienced directors to oversee the
continued execution of our strategy and positioning of Tessera for sustainable
growth and profitability.

STARBOARD’S FLAWED STRATEGY LACKS DETAIL AND WOULD DESTROY STOCKHOLDER VALUE

Notwithstanding our progress, Starboard, an activist hedge fund owning
approximately 7.6% of Tessera common stock, would like to take control of your
Board and change the Company's direction – all without paying a control
premium.

Even more troubling for Tessera’s stockholders is Starboard's failure to
provide a detailed new business plan. At best, the few suggestions it has made
are actions that we have already implemented or announced and, at worst, they
reflect an utter lack of understanding of our business. For example, Starboard
wants to force the Company to significantly reduce our in-house IP research
and development efforts and expenses. Starboard clearly does not understand or
appreciate that our innovations drive the sustainability and growth of our IP
revenue stream. Starboard’s Peter Feld doesn't believe engineering is an
essential tool in the development of our portfolio; he sees engineering as a
commodity that can "just be purchased from companies who have failed to exert
their rights to those patents."

Nothing could be further from the truth.

Tessera has built a mosaic of technology patents and know-how that provide our
licensees with time-to-market and performance leadership. Tessera continues to
invest in these technologies to ensure our licensees see continued value in
the IP and know-how they receive, and our customers look to our patent assets
to bring new and enhanced products to market.

Moreover, we believe that Starboard’s fundamental lack of knowledge of the IP
business is a reason why Unwired Planet, whose board is led by Starboard’s Mr.
Feld, has seen its revenues decline rapidly to such anemic levels. Your vote
will help determine whether Tessera will meet the same dismal fate as Unwired
Planet.

So why is Starboard really pushing such a flawed and flimsy agenda in support
of its proxy fight for control? We would not be surprised if Feld had an
undisclosed financial agenda to make money at the expense of Tessera
stockholders by merging Tessera with a company in dire financial straits.

We believe that electing the Starboard slate would put stockholder value at
serious risk by installing underqualified and conflicted director nominees
seeking to implement a flawed agenda and disrupt a strategy that is gaining
momentum. We urge you to support the appointment of all six of the Company's
nominees as directors of the board by casting your votes using the GOLD proxy
card.

PETER FELD’S HISTORY OF PROBLEMATIC ACTIONS

Peter Feld has a history with Tessera, having attempted to gain board seats in
the prior year with minimal ownership. This time he has launched a proxy fight
to take majority control of Tessera without paying a premium and without any
concrete details of a new plan or a management team that will drive increased
stockholder value. Moreover, Feld has launched this proxy fight despite his
clear conflicts of interest, poor track record as the chairman of an IP
competitor, Unwired Planet, and troubling, undisclosed and unanswered
questions about allegations of conflicts of interest and ethics violations
raised about one of his nominees.

Feld’s history of problematic actions raises questions about his true agenda:

1. Appallingly poor track record as chairman of ailing IP competitor Unwired
Planet.

Since becoming chairman at IP competitor Unwired Planet on September 9, 2011,
Feld has overseen a company that has generated a paltry $35,000 in total
revenues from the fourth quarter of 2011 to the fourth quarter of 2012, while
licensing and litigation expenses have totaled nearly $20 million and cash
loss from operations have totaled over $56 million in the same period.

Additionally, Feld has effectively put in place a “poison pill” at Unwired
Planet by establishing a potential $1 billion payment to Ericsson should a
change of control of Unwired Planet occur in the first three years.

2. Troubling questions about one of his nominees.

Feld failed to disclose that one of his nominees, attorney Donald Stout, has a
history of questionable ethical practices. Courts that examined how Stout came
to control the patents underlying the Blackberry suit found that actions Mr.
Stout was alleged to have engaged in would constitute “a clear case of
conflict of interest” and would violate “any number of Virginia professional
ethics rules.” More importantly, although Stout has patent litigation
experience, he would not pass our Board’s rigorous screening and nomination
process.

As a result, we believe certain of Starboard’s nominees would destroy value
for Tessera’s stockholders, and all of them are tethered to Starboard's flawed
agenda. Our Nominating Committee carefully reviewed the Starboard slate and
determined that certain individuals lack the qualifications and experience to
be suitable candidates for the Board. The Nominating Committee also determined
that certain Starboard nominees had what appeared on paper to be solid
credentials worth exploring; unfortunately, despite numerous requests,
Starboard would not permit our Nominating Committee to talk with those
nominees and evaluate their merits.

TESSERA’S BOARD AND MANAGEMENT ARE SETTING THE STAGE FOR A PROFITABLE FUTURE

Tessera’s Board and management are aggressively positioning the Company to
benefit from our customers’ continued reliance of our IP portfolio and the
market’s demand for DOC’s superior MEMS-based autofocus technology.

We are making significant progress.

Now is not the time to disrupt that work. Please vote for Tessera’s six
nominees and make sure that your interests are protected as your committed and
energized Board continues to build and deliver value for our stockholders,
today and in the future.

EXPANDING THE BOARD TO CONTINUE ADDING FRESH PERSPECTIVES

We also commit that, if elected, our nominees will endeavor to expand the
board by two, and add the two most qualified Starboard candidates. We are not
opposed to fresh views on the board, nor do we take issue with all of the
Starboard nominees.

Like you, we simply want what is right for Tessera and all of its
stockholders.

Your vote is important in this election, and we urge you to vote TODAY so that
your voice is heard. To elect the Tessera Board’s nominees, we encourage you
to vote today by telephone, by Internet, or by signing and dating the enclosed
GOLD proxy card and returning it in the postage-paid envelope provided. It is
imperative to know as a stockholder, voting on the WHITE card and withholding
on all Starboard nominees does not have the same effect as voting on the GOLD
card. Only the card that has the latest date counts, and you cannot submit two
cards in an effort to pick and choose between the two slates. We urge you to
discard all WHITE proxy cards sent to you by Starboard.

Sincerely,

Richard S. Hill

Interim Chief Executive Officer and Executive Chairman
