January 19, 2005

Mr. George M. Monk
[Address]
[Address]

Dear George,

I am pleased offer you the position of VP Finance and Acting CFO at Macrovision
Corporation (the "Company"), reporting to me. This job location is based in our
offices located at 2830 De La Cruz Blvd in Santa Clara and does not involve
telecommuting. In your role as Acting CFO, you will be responsible for all
accounting and finance functions and have worldwide accounting and finance
personnel reporting to you (however, personnel in legal, human resources and MIS
departments will report to me).

Your position will also include serving as Macrovision's Principal Accounting
Officer and signing the periodic reports of the Company in such capacity, which
will be filed with the Securities and Exchange Commission ("SEC"). Upon your
first day of employment, your position of VP Finance and Acting CFO will be
added to our directors and officers liability insurance policies ("D&O
Insurance") as an insured person under such policies. Prior to signing the
periodic reports to be filed with the SEC, the Company's chief legal officer
will provide you with an opinion as to whether there are any additional
liabilities that to the Company's knowledge that will not be covered by D&O
Insurance policies and the standard indemnification provisions contained in the
bylaws of the Company.

Your compensation will consist of a base salary of $190,000 annually. You will
also be eligible to participate in our EIP (Executive Incentive Plan) for the
2005 calendar year. I anticipate that within the next month the compensation
committee will approve the 2005 EIP Plan with few changes to the 2004 Plan which
provided a payout at 100% achievement of targets equal to 40% of your earned
salary. The EIP bonus payout is split with 50% based on the Company meeting both
its revenue and EBIT plan, and 50% based on your achievement of specific MBO
objectives that you and I will develop together. I have attached a copy of the
2004 EIP Plan for your review.

You will be eligible to receive gross (taxable) bonuses as follows: $15,000 upon
acceptance of this offer of employment and your first day of employment, $22,000
upon your 1 year anniversary of employment and $20,000 upon your 2 year
anniversary of employment. In the event that you voluntarily terminate your
employment with Macrovision prior to May 1, 2005, the signing bonus will be
reimbursed to Macrovision. In order to receive each of these bonuses, you must
be employed by Macrovision at the time such bonus payment is due and such bonus
payment shall not be prorated for any interim periods.

Additionally, you will receive a 100,000 share stock option grant, which needs
to be approved by the Compensation Committee of the Board of Directors. The
price per share for this grant will be set at the closing market price of
Macrovision Corporation stock (NASDAQ: MVSN) on your first day of employment.
These options will vest in 3 years in accordance with the terms and conditions
of the Macrovision Corporation 2000 Equity Incentive Plan as follows: 3,000
shares per month for the first twelve months of your employment, 2,500 shares
per month for the next twelve months and 2,833 shares per month for the final
twelve months.

As long as the Company continues with its current employee stock option program
(which may be curtailed if FASB implements mandatory stock option expensing
rules, or may be changed at will by the Board of Directors) you will be eligible
for annual refresh grants that are typically awarded twice per year based on
performance and prior initial grant levels.

                                   -- MORE --

As a Macrovision employee, you will receive our standard benefits including
Flexible Time Off (FTO), Paid Holidays, Medical, Dental, Life, Accidental Death
and Dismemberment, Long-term and Short-term Disability coverage, and enrollment
into our Employee Stock Purchase Plan (ESPP), Medical Spending and 401(k) Plans.
A description of our benefits is attached. Additionally, your salary, along with
your performance, will be reviewed in one year from your date of hire (your
anniversary date). These, and other matters, will be fully explained to you
during your orientation; however, feel free to contact me or George Greeley, our
Director of HR, with any questions prior to that time.

In compliance with the Immigration Reform and Control Act of 1986, we are
responsible for verifying employment eligibility of all new employees. If you
choose to accept our offer, please bring with you on your first day documents
that show both proof of your identity and your eligibility to work (i.e.,
state-issued driver's license, U.S. passport, social security card, birth
certificate, etc.). In addition, in order to verify your recent salary and
compensation, you are asked to bring your W-2 forms (or other evidence of your
work-related compensation) for two of the last three years: 2002, 2003, 2004.
This offer of employment is contingent upon your providing the appropriate
identification and salary history information.

As Macrovision's relationship with employees is at-will, either you or
Macrovision may terminate the employment relationship at any time for any
reason, with or without notice. Between your date of hire and July 31, 2005, if
you resign or your employment is terminated because of a demonstrated inability
to perform the duties of the job to a level normally expected of the position,
or for "Cause" (as defined below), you will not receive any severance pay
benefits from Macrovision. Between August 1, 2005 and December 31, 2005, if you
resign or are terminated for any reason other than Cause, you will be paid a
severance pay benefit equal to seven months of your then current annualized base
salary plus your prorated EIP bonus at the 40% target for the total months
employed up to 12 months; provided, however, that if you accept alternative
employment during such seven-month severance period, your severance payments
will be reduced by the amount of your new monthly salary. Such severance pay
benefits will be payable ratably over the seven month period after termination
in accordance with Macrovision's regular pay periods. After December 31, 2005,
if you resign or your employment is terminated for any reason, you will not
receive any severance pay benefits from Macrovision. Notwithstanding the
foregoing, if you remain employed by Macrovision after December 31, 2005, you
will be offered our standard Executive Severance and Employment Agreement that
will be effective as of January 1, 2006. The intent of such agreement is to
protect you and provide accelerated stock option vesting and a minimum of
6-months' severance pay should a `Change of Control' (as such term is defined in
the Executive Severance and Arbitration Agreement) of the Company occur and
should you lose your job or have your job materially diminished in title, job
function, or salary as a result.

 "Cause" means the occurrence of any one or more of the following: (i)
conviction of any felony or any act of fraud, misappropriation or embezzlement
which has an immediate and materially adverse effect on the Company, (ii)
engaging in a fraudulent act to the material damage or prejudice of the Company
or in conduct or activities materially damaging to the property, business or
reputation of the Company, (iii) your failure to comply in any material respect
with any written policies or directives of the Board which have an immediate and
materially adverse effect on the Company and which have not been corrected
within 30 days after written notice from the Company of such failure, (iv) any
material act or omission involving your malfeasance or negligence in the
performance of employment duties which has an immediate and materially adverse
effect on the Company and which has not been corrected within 30 days after
written notice from the Company, or (v) material breach of any other agreement
with the Company by you, which has an immediate and materially adverse effect on
the Company and which has not been cured within 30 days after written notice
from the Company of such breach. Upon a termination of employment for Cause,
your right to receive compensation and benefits shall terminate immediately upon
the effective date of the termination for Cause. Without limiting the foregoing,
you shall not receive any base salary for any period after the effective date of
any such termination for Cause, shall not receive any EIP bonus for any year
during which any such termination for Cause occurs and shall not be entitled

                                   -- MORE --

to further vesting or accelerated exercisability of any Stock Options following
any such termination for Cause.

Any dispute arising out of or relating to your employment with Macrovision,
including, but not limited to, the manner in which that employment is
terminated, or any claims that Macrovision has violated any state or federal
civil rights laws shall be submitted to binding arbitration under the
administration of the American Arbitration Association. It is understood that
with respect to the at-will employment relationship and the binding arbitration
provision stated above, that this constitutes the full, complete and final
expression of the agreement with Macrovision, and that it may not be modified,
altered or amended, either expressly or impliedly, unless in writing signed by
the CEO of Macrovision.

As a matter of policy, we like to make it clear that if a prospective employee
accepts our offer, he/she should not bring to Macrovision from his or her
previous employers any drawings, documents, customer lists, or similar material.
Although this caution is in most cases unnecessary, we feel that it is important
to emphasize that the Macrovision policy prohibits the transfer or use of such
material from other employers. Additionally, as a condition of employment, all
employees must sign a Proprietary Information and Inventions Agreement, as well
as our Securities Trading Policy, both of which are attached.

George, I look forward to your joining Macrovision and helping us grow our
finance department capabilities to meet the challenges of scaling our business.
I think you can bring an energy level and attention to process that will be very
beneficial to the Company. And I think you will find that your personality and
approach to business is a good fit with our culture and our team orientation. If
the foregoing meets with your approval, please indicate by signing below and
returning a copy of this letter to me no later than January 21, 2005.

Sincerely,

/s/ William A. Krepick

                                   -- MORE --SECOND AMENDMENT TO EMPLOYMENT AGREEMENT BETWEEN DIGITAS AND DAVID KENNY

 EXHIBIT 10.1 
  
 AMENDMENT TO EMPLOYMENT AGREEMENT 
  
 This SECOND AMENDMENT TO EMPLOYMENT AGREEMENT dated as of January 21, 2005 between Digitas Inc., a Delaware corporation (the
“Company”), and David W. Kenny (the “Executive”). 
  
 WHEREAS,
the Executive is currently employed as Chairman and Chief Executive Officer of the Company, under an Employment Agreement dated January 6, 1999, as amended on February 1, 2000 (collectively, the “Agreement”); and 
  
 WHEREAS, the Board of Directors of the Company has authorized certain severance provisions in
respect of senior executives of the Company, and the parties hereto consider it appropriate that the Agreement be amended to reflect such provisions; 
  
 NOW, THEREFORE, the Company and the Executive agree to the following amendment to the Agreement. Defined terms used in this Amendment shall have the same meanings as in
the Agreement. 
  
 1. Section 4(d)(i) of the Agreement is deleted and replaced
with the following: 
  
 “(i)     For a
period of twenty-four months after the Date of Termination, the Company shall continue to pay the Executive (A) the Base Salary at the rate in effect immediately before the Date of Termination (but, in the case of a termination by the Executive for
Good Reason, disregarding any reduction thereof that was the basis for such termination) and (B) a bonus amount (the “Bonus Amount”) equal to two times (2x) the average of the annual bonuses paid to the Executive for the three years
immediately preceding the year of the Date of Termination. If no bonus was paid to the Executive for the year immediately preceding the year of the Date of Termination, the Bonus Amount shall be calculated at fifty percent (50%) of the Base Salary
multiplied by two (2x); 
  
 2. Section 4(d) of the Agreement is amended to include
the following section following subsection (v): 
  
 “(vi)     Restricted stock previously granted to the Executive shall become vested immediately.”
