                  2001 and then conclude with our corporate goal for 2002. We
                  will then take your questions. Kevin Starr will now review our
                  key financial results, Kevin.

Kevin Starr:      Thanks Gina, and good afternoon to everybody. I'm pleased to
                  report the financial results for another very important year
                  at Millennium in building the leading biopharmaceutical
                  company. Our operating profile continues to reflect our
                  progress, including our strong balance sheet and ongoing
                  success in achieving our commitments to existing and new
                  alliance partners. For the full year 2001, revenue was $246.2
                  million, compared to $196.3 million for 2000. Millennium's
                  alliance strategy continues to provide the company with
                  significant funding used to build the enterprise.

                  Expenditures for research and development for the year ended
                  2001 were $400.6 million, versus $268.7 million for 2000. This
                  increase represents our continued investment in building a
                  sustainable product pipeline of important programs in major
                  franchise areas. General and administrative expenses for the
                  year ended 2001 were $82.7 million, versus $49.3 million in
                  2000. This increase is largely due to the expansion of
                  Millennium's commercial organization, other business groups,
                  and facilities and infrastructure necessary to support the
                  growth at all levels of our business.

                  Other income, on a net basis, for the year ended 2001 was
                  $112.1 million, versus $29.8 million for 2000. This increase
                  is due to a higher level of invested funds, as well as a $20
                  million payment related to our December 2001 restructuring of
                  our partial interest in Millennium and Ilex Partners limited
                  partnership. Net loss before acquisition related charges and
                  debt conversion expenses for the year ended 2001, was
                  consistent with guidance that we provided earlier in the year,
                  at $124.9 million, or 57 cents per share. This compares to a
                  net operating loss of $92 million, or 48 cents per share for
                  2000.

                  In addition, during 2001 Millennium recorded amortization
                  charges of $64.6 million, related to the 1999 acquisition of
                  Leukocyte [sp] and the 2000 acquisition of Cambridge Discovery
                  Chemistry from Oxford Molecular Group. As of December 31,
                  2001, Millennium had approximately $1.5 billion in cash, cash
                  equivalents and marketable securities. This meets our goal of
                  positive cash flow for the year.

                                                   January 22, 2002/3:00 p.m. MT
                                                                    Page 3 of 15


                  Now lets turn to our financial outlook for 2002. The guidance
                  is consistent with that previously announced in a press
                  release on January 7, 2002. Please note that this guidance
                  includes the impact of our merger with COR Therapeutics, we do
                  expect this transaction to close on February 12, 2002, as we
                  incurred and received earlier termination of the waiting
                  period under the Hart-Scott-Rodino Antitrust Act, and the SEC
                  has declared our S4 affective.

                  Our 2002 guidance reflects a continuation of our strategy of
                  leveraging our strong balance and making balanced investments
                  in building a leading biopharmaceutical company. To accomplish
                  this goal, this year we will focus our investments on
                  Integrilin growth and the continuation of building a
                  sustainable product pipeline across businesses in our now four
                  franchise areas, cardiovascular, oncology, inflammation and
                  metabolic disease.

                  We will build this investment onto our investment strategy for
                  a sustainable pipeline with 10 molecules in the clinic, and
                  three to four more new molecules headed to the clinic in 2002.
                  This will be followed by a goal of over five molecules
                  entering the clinic each year, beginning in 2005, and we'll
                  continue amassing the critical mass necessary to make this
                  happen. 2002 will have over $500 million in R&D spending, and
                  one of the strongest balance sheets in the industry. Now lets
                  turn to some of the specific guidance.

                  First lets start with revenue. In 2002 revenue will consist of
                  two components, Integrilin sales and strategic partnerships.
                  We expect worldwide Integrilin sales to increase 30% to
                  approximately $300 million in 2002. Of that Millennium expects
                  to record revenue of approximately $150 million. In addition,
                  we expect strategic alliance revenue of approximately $250
                  million, for a total revenue target of over $400 million for
                  the year.

                  Second, research and development expense. In 2002 we expect to
                  continue our investment strategy in our R&D efforts, resulting
                  in a total annual research and development spending in excess
                  of $500 million. The focus of these investments will include
                  expanded development programs for MLN341 and Integrilin, new
                  and ongoing clinical trials, continued investment in our
                  discovery engine and our industry-leading platform.

                  Third, net operating loss. As a result of these investments,
                  we expect to record a net loss from operations in the range of
                  $175-200 million for 2002. Fourth, cash and debt. We expect to
                  end 2002 with a very strong balance sheet, with a cash target
                  in excess of $1.7 billion and approximately $250 million in
                  long-term outstanding debt. In addition, acquisition related
                  charges, in addition to net loss from operations, Millennium
                  will record the following charges related to our acquisition
                  of COR Therapeutics. The acquisition is valued at
                  approximately $1.9 billion and will be accounted for as
                  follows, approximately $250 million will be recorded as a one
                  time, non-cash charge in 2002, for in process research and
                  development. Approximately $500 million of the total value
                  will be allocated to intangible assets, primarily related to
                  Integrilin. These specifically identified intangible assets
                  will be amortized over a 13 year period, with the 2002 impact
                  expected to be approximately $28 million. The remainder,
                  approximately $1.2 billion, will be allocated to net tangible
                  assets acquired and good will.

                  So with that, let me turn the call over to Mark.

Mark Levin:       Thanks Kevin, and good afternoon everybody, and happy New
                  Year. Today I will discuss the progress we've made in creating
                  a leading biopharmaceutical company. I will focus my remarks
                  on our overall vision, our four franchise areas, our
                  accomplishments made in 2001, and then I will review our
                  corporate goal for 2002, including delivering on our promise.
                  But first I'd like to start on an overview of where we are
                  with the COR/Millennium merger.

                                                                    Page 4 of 15


                  On December 6 we announced our intention to merge with COR
                  Therapeutics, and we expect to close on February 12, a little
                  over two months from the day of announcement, an amazing
                  effort on the entire team's part. The merger brings us the
                  following, the number one cardiovascular franchise in
                  biotechnology, with the leading inject able anti-platelet drug
                  on the market, and three to four additional molecules in the
                  clinic by year-end. It continues to build on one of the top
                  oncology franchises in the industry today, with one
                  therapeutic product on the market and a total of five to seven
                  molecules in the clinic by year-end. It brings us a leading
                  commercial organization in the United States, which we will be
                  expanding into oncology in both US and Europe. It brings us a
                  biological effort that strengthens all four franchises. And
                  finally, a very strong team that continue to build Millennium
                  for long-term success. This merger gives Millennium the
                  platform to deliver on our promise.

                  Let me just start off and summarize again for everybody our
                  vision, mission and strategy. Millennium's overall vision is
                  transcending medicine, making a difference in the quality of
                  people's lives. That is why we're all at Millennium. In order
                  to make a difference, we are building the leading
                  biopharmaceutical company with three key strategies. First of
                  all breakthrough products, products based on the cause and
                  pathway of human disease, and a sustainable pipeline,
                  something not done today in biotechnology. Secondly, the
                  combination of personalized medicine and productivity, these
                  are the core sells of our revolution in changing the future of
                  medicine and the future of the industry. And we wrap all this
                  together with a value creation model and commitment to
                  shareholders that is based on a sustainable pipeline,
                  personalized medicine, productivity and business innovation.
                  It is these key efforts that feed into an overall model that
                  we monitor and use to make decisions on a monthly and annual
                  basis to drive shareholder value.

                  Let me now go into more detail about the status of the
                  programs of each one of our franchise areas, and I'll start
                  with cardiovascular. Overall the cardiovascular area is the
                  leading franchise in the industry today, representing over $40
                  billion in sales. As a result of the merger with COR, we will
                  have Integrilin, the leading product in its class. And behind
                  that, a very strong clinical pipeline in the cardiovascular
                  area. Integrilin is a breakthrough product for acute coronary
                  syndrome. It's the number one anti-platelet agent in the IV
                  area, with $230 million in sales, representing 33% growth in
                  2001. Market share is now over 50%, which is a remarkable
                  accomplishment achieved over the last couple of years. We
                  expect 30% annual growth toward a $500 million plus market
                  opportunity over the next several years.

                  A second molecule behind Integrilin is Factor 10A, a very
                  important molecule in the overall anticoagulant area. This is
                  going to be a potential replacement for cumadin, a potential
                  multi billion-dollar market. We will end the year with four to
                  five molecules in the clinic, with an exciting discovery
                  pipeline.

                  Now let me talk about oncology. Genomics milicro pathway
                  biological systems again will drive our efforts in oncology.
                  Oncology is the leading area of unmet need in the world today,
                  and in collaboration with our partners, Millennium has brought
                  two oncology products to the market. In addition, Millennium
                  has a deep clinical and pre-clinical pipeline in the oncology
                  area. Our proteasome inhibitor, MLN 341 is a very important
                  molecule. We reported exciting preliminary data late last year
                  in early phase two studies in multiple myeloma. We believe
                  proteasome inhibition is a major point of intervention now in
                  the oncology area. MLN 341 represents a great opportunity for
                  us. New recons and new pathways, broad applications, liquid
                  and solid tumors and a very, very broad iloxial property
                  estate.

                  Our anti PSMA program is an antibody that selectively targets
                  PSMA, a protein or antigen uniquely [unintelligible] on the
                  surface of virtually all prostate cancer cells. PSMA
                  expression increases with advanced tumor grade and disease
                  phase, so as the disease gets worse, PSMA




                                                      MILLENNIUM PHARMACEUTICALS
                                                                  Res. #20147577
                                                           Moderator: Mark Levin
                                                   January 22, 2002/3:00 p.m. MT
                                                                    Page 5 of 15


                  expression increases. ML 591 is now in phase one trials with
                  the [unintelligible] molecule, and we are very excited about
                  what we have seen so far. We expect to have a toxin conjugate
                  at phase one later this year.

                  In the receptor tyrosine kinase area, COR submitted an I&D for
                  CT5351A this past December. If things go well, this will be in
                  the clinic soon for acute myeloid leukemia. So as we look at
                  the overall oncology program, we have two products on the
                  market, 341 and 591 in the clinic, and by year-end we'll have
                  five to seven molecules in clinical trials with a deep
                  discovery effort in antibodies and small molecules.

                  Now let me summarize the inflammation franchise. Inflammation
                  is certainly one of the major markets, with over $25 billion
                  in sales today. We're working with rheumatoid arthritis,
                  asthma, IDD, multiple sclerosis and other major areas.
                  Millennium has two molecules in the clinic, 977 and MLN 02;
                  phase two data will be available on both of these programs
                  later this year. We will end the year with three to four
                  molecules in the clinic out of our inflammation franchise.

                  In addition we have strong expertise and a very exciting 50/50
                  partnership with Aventis in this area. Combined with Aventis
                  we have over 350 full time people working just in discovery on
                  these diseases. It's an extraordinary effort, probably one of
                  the largest in the world, on these diseases.

                  And finally, the metabolic franchise. We have a major effort
                  now in obesity across all the different organ sets. We're
                  looking in the brain at satiety and hunger. We're looking at
                  the gut in absorption. We're looking at adipose tissue for
                  thermo genesis, and we're driving a very important deep
                  discovery pipeline forward. Obesity clearly is going to be one
                  of the largest franchises going forward. Tens of millions of
                  people have this disease. Our first molecule, MLN4760, was put
                  in the clinic late last year and there is a potential for
                  another molecule to go into the clinic this year. We have a
                  very important relationship with Abbott, 50/50 around the
                  world, commercialization included. Combined, over 250 people
                  in research now working on driving molecules into the clinic.

                  So in summary, a little over three years ago we were talking
                  with you about genes and targets. Now those genes and targets
                  make up four franchise areas with tremendous potential in the
                  marketplace, and we've done all of this in just a few short
                  years. So let me go back now and summarize the 2001
                  accomplishments. A year ago as we always do, we stated our
                  goals for 2001. I'll now review our accomplishment toward
                  those goals, and I'll break it down into the four key
                  categories. First, breakthrough products. We stated we would
                  have CamPath on the market, CamPath was launched in the United
                  States in June and Europe in August, this goal was
                  accomplished. We said we expected to make rapid clinical
                  progress on MLN 341 by starting phase two multiple myeloma
                  trials and also multiple phase one solid tumor trials. Done.

                  In our inflammation franchise we expected to finish enrollment
                  with MLN02 in phase two trials in patients with Crohn's
                  disease and to initiate a phase two trial with MLN02 in
                  patients with ulcerative colitis. We met our goal on both of
                  these. Also out of our inflammation franchise we met our goal
                  of initiating phase two trials with MLN 977, for treatment of
                  patients with asthma. We expected to expand the breadth of
                  both clinical and pre-clinical pipelines overall by putting 12
                  new molecular entities into the clinic and another 12 new
                  molecular entities into lead optimization and pre-clinical
                  development. We feel that we did very strong justice to this
                  set of goals. While we did not get 12 into the clinic, we got
                  10 in plus one I&D filed, and through the merger with COR, one
                  additional product on the market. And we surpassed the lead
                  optimization pre-clinical goal by advancing 13 programs.

                                                                  Res. #20147577
                                                           Moderator: Mark Levin
                                                   January 22, 2002/3:00 p.m. MT
                                                                    Page 6 of 15


                  We had also stated that one to two of the molecular entities
                  in the clinic would be genomically derived. We succeeded in
                  that goal in November when we announced the initiation of
                  phase one trials with MLN 4760 for the potential treatment of
                  obesity. Let me now move on to the productivity and
                  personalized medicine goals for 2001.

                  In addition to generating $80 million in revenue from our
                  productivity platform, which we said we would, we aggressively
                  continue to move the platform downstream. We are now
                  addressing bottlenecks within the clinical process and have
                  initiated multiple efforts from [unintelligible].

                  We have signed another of important partnerships to move our
                  platforms downstream into pharmacogenomics and admin. These
                  include collaborations with Far Side, Structural Genomics and
                  Abbott, to name a few.

                  And we also expected to make aggressive strides to expand the
                  depth and reach of our unparalleled pipeline and met that goal
                  by characterizing more than 2,000 drugable [sp] targets, and
                  more than 70 high through put screens. Let me now move onto
                  the final category, Valuperation [sp].

                  We said that we would continue to implement our M&A strategy
                  to bring in late-stage molecules products, technology and
                  capabilities, and we feel we've been very highly successful in
                  meeting that goal through our Cor merger. We signed a 50-50
                  deal with Abbot in the area of metabolic disease early in the
                  year, thus meeting our metabolic disease goal. We set forth as
                  a goal an aggressive [unintelligible] licensing strategy and
                  have met that goal by bringing in several clinical and
                  pre-clinical programs, including MLM 591 for Prostate Cancer,
                  GCC for Colin Cancer and a portfolio of new candidates to work
                  in a manner similar to Dual Topolyte [sp] Tyrosine inhibitors
                  but with nominal DNA damaging mechanisms of action for solid
                  tumors.

                  From an intellectual property standpoint, we exceeded our goal
                  of 200 issued patents and 2,000 patent applications. In short,
                  it was a great year for all of us at Millennium. We end this
                  year with two therapeutic products on the market, four
                  franchise areas, 10 molecules in the clinic and one of the
                  strongest financial positions in the industry.

                  Let me now move onto our 2002 goals. Our first set of goals,
                  we [unintelligible] are our overall goal of building a
                  sustainable pipeline of very [unintelligible] products, a key
                  strategy in our objective of creating the leading
                  biopharmaceutical company. First, we intend to generate a 30%
                  increase sales in the worldwide sales of Integrilin for a
                  total of $300 million. We intend to accomplish through a
                  variety of initiatives, including seizing market share,
                  growing the market through our innovative Crusade trial and
                  adding new indications for this blockbuster product.

                  Two, we plan to initiate a Phase III trial for Millennium MLM
                  341 in multiple Myeloma in the first half of 2002. We and a
                  number of clinicians are very excited about the promise of
                  this drug. So the initiation of Phase III trials represents a
                  significant step forward in bringing this drug towards
                  commercialization. We will also continue a very aggressive
                  combination trial program in solid tumors.

                  Three, we plan to enter three to four new molecular entities
                  in the clinic. As you could probably surmise form my
                  discussion of our four franchise areas, we have a very deep
                  pre-causal pipeline from which to draw these clinical
                  candidates in 2002.

                  Four, like last year, we intend to deliver our 75 high through
                  put screens, which has been and will continue to be a key
                  factor in our discovery engine and key to a long-term
                  sustainable pipeline.

                  And fifth, under product pipeline, is our overall total R&D
                  investment. As Kevin said, it's expected to be over $500
                  million for 2002, which is in the top of the biotechnology
                  industry. This considerable research and discovery effort will
                  drive the acceleration of our clinical pipeline as well with
                  moving the discovery in pre-clinical compounds forward
                  quickly. All of this is directed towards building a steady
                  stream of novel and important products, through the
                  development process, towards the markets and patients.

                  And the next category of goals relates to personalized
                  medicine and productivity, the cornerstone of our revolution
                  to changing the future of medicine and the pharmaceutical
                  industry. We believe in marshaling the forces of personalized
                  medicine productivity will be necessary to create a major
                  biopharmaceutical company that generates products that make a
                  difference in peoples' lives.

                  In 2002, we will have a major effort underway to incorporate
                  pharmacogenomics in six clinical programs, which we believe
                  represents the strongest commitment in the industry to this
                  effort.

                  And finally, on the Valuperation side, we continue to target
                  break-even in 2004. We will continue to pursue merger and
                  acquisition opportunities of both products and companies as we
                  did last year. We will continue to see transforming alliances
                  with pharmaceutical companies and others. And we will end the
                  year with a strong balance sheet of approximately $1.7 billion
                  in cash, and $250 million in long-term outstanding debt.

                  So in summary, Millennium is delivering on our promise of
                  building a major biopharmaceutical company. We have the
                  leading injectable anti-platelet drug growing to $300 million
                  in 2002. We have 10 molecules in the clinic, with three to
                  four new molecules in the clinic in 2002. We have 341 entering
                  Phase III trials for multiple Myeloma in the first half of
                  2002, and important combination trials for solid tumors
                  continuing. We are building a sustainable pipeline, with
                  five-plus molecules entering the clinic and one to two new
                  products entering the markets [unintelligible] every year
                  beginning in 2005. This has never been done before in
                  biotechnology.

                  The critical mass necessary to make it happen, $500 million in
                  R&D and one of the strongest balance sheets in the industry,
                  the vision of personalized medicine and productivity and the
                  ability to build the biopharmaceutical company of the future
                  and to make a difference in the totality of peoples' lives.
                  With that, I'll turn it over to our operator for questions.
                  Thank you very much.

Operator:         At this time, we will take any questions you may have. If you
                  have a question, please press the one followed by the four on
                  your touchtone phone, and you will hear a three-toned prompt
                  to acknowledge your request. If you would like to cancel your
                  question please press the one followed by the three. Your
                  first question comes from Maykin Ho, Goldman Sachs. Please go
                  ahead.

Maykin Ho:        Hi Mark.

M. Levin:         Hi Maykin, how are you?

M. Ho:            Thanks. On the 341 program, can you give us a little bit more
                  detail in terms of the Phase III trial for [unintelligible]
                  Myeloma? And also, some of the studies that we might be seeing
                  results on this year on solid tumors?

M. Levin:         Yeah, Maykin. John Maraganore's going to do that.

J. Maraganore:    Hi, Maykin. The 341 program is still--the final design is
                  still being finalized. We're looking at a trial that will be
                  between 400 and 600 patients. We'll be randomizing patients to
                  receive either 341 or high-dosed Exemethizone [sp]. Patients
                  enrolled in the trial will include relapse patients as

                                                   January 22, 2002/3:00 p.m. MT
                                                                    Page 8 of 15


                  well as patients that have refractory. And, we plan to conduct
                  the trial in over 50 sites. We believe that the end point for
                  the trial will be timed to disease progression.

M. Ho:            And the other tumors?

J. Maraganore:    We continue to have aggressive programs, as you know, on the
                  solid tumor setting, in addition to our studies that we
                  started earlier last year with [unintelligible]. We recently
                  started a program with Haxatier [sp]. We expect to have much
                  of these data in addition to additional Myeloma data at the
                  upcoming Asco meeting in May.

M. Ho:            Oh, that's great. And, is Vaughn on the phone?

J. Maraganore:    Vaughn is.

M. Ho:            Hi Vaughn. Can you tell us a little bit about the status of
                  Integrilin, what you're seeing in the marketplace, in terms of
                  share? And also the usage and duration setting?
                  [Unintelligible-background noise] it comes to Crusade?

V. Killian:       Sure. In terms of usage, our market share in the November
                  timeframe, our patient market share was in the low 50s. We
                  crossed over the 50% level and now we're seeing our market
                  share in the mid-50s. So the market share is continuing to
                  grow for Integrilin on a patient basis. And obviously, the
                  dollars lag that but are tracking in the same direction.

                  In terms of Crusade, Crusade is enrolling sites right now and
                  we're going to have our first pass at data from hospitals at
                  the ACC meeting in March.

M. Ho:            OK. And, what are you seeing in terms of duration of usage and
                  the usage in the emergency room?

V. Killian:       You know we don't expect to get the results from that market
                  research survey until mid-February. So I would imagine that
                  sometime around the ACC we'd be making that data available.
                  We don't have the most recent data in house, Maykin.

M. Ho:            OK.

V. Killian:       OK?

M. Ho:            It seems that from market share data then it seems that the
                  pick up due to September 11th is now working its way through?

V. Killian:       Yeah. You know, there are several dynamics that were going on
                  there. One was, as you recall we had to get our sales force
                  back to full strength, get over that lull of September.
                  Actually right now, Mark, Kevin and I were all, and John as
                  well, at our national sales meeting, we have all of our sales
                  force here getting excited about the new merger and focusing
                  back in on Integrilin and we have, I believe, darned near a
                  full sales force.

                  We have one territory opened. I'll save it for you, if you
                  want.

M. Levin:         Hey Maykin, this is Mark. Several of us sat in on that meeting
                  most of the day today. I'll tell you, the excitement in the
                  room about Integrilin but also the merger between the two
                  companies was just incredible. And, you know, I came away from
                  that even more convinced that this is going to be just a
                  wonderful, extraordinary merger.

M. Ho:            That's good to hear. Thank you very much.

Operator:         Your next question comes from Matt Geller, with CIBC World
                  Markets. Please go ahead.

Matt Geller:      Hi, could you go into some more details about MLN-02, in terms
                  of what we might expect to learn from the Phase II? What the
                  design of the study and what the timing is and what other
                  [unintelligible] studies it might lead to?

J. Maraganore:    Hi Matt, John Maraganore.

M. Geller:        Hi.

J. Maraganore:    MLN-02, as you know, is our Anti-Alpha 4 Beta 7 antibody. This
                  is a de-immunized antibody directing, effectively, a surgical
                  strike at blocking T-Cell migration to the inflamed
                  [unintelligible] in inflammatory bowel disease. And we believe
                  this is a drug that's got potential, not only in Chron's
                  disease, which is where drugs like Remacaid [sp] and Emberol
                  [sp] are currently proven to be effectively. But also in Ulcer
                  Colitis, which is effectively an untapped market today, with
                  the existing drugs, biologics that have been introduced in
                  IBD.

                  We completed, in December, our Chron study. This is a study of
                  180 patients. It was a multi-dose, placebo-controlled, double
                  blind randomized study across multiple centers, largely in
                  Canada. And we will be reporting on the results of that study
                  in the first half of this year.

                  The end point of that study is the Chron's Disease activity
                  index, which as you know Matt, is the standard end point that
                  is used for measuring efficacy of a drug. The nice thing about
                  that end point is that it also turns out to be an approvable
                  end point from the FDA. But that obviously would come out of
                  our Phase III studies.

M. Geller:        Will that be presented at DDW this year?  Or--?

J. Maraganore:    The timing-we're having to finalize the timing on that. It
                  won't be a formal presentation at DDW, but the results may
                  coincide with that meeting.

M. Geller:        And is this a controlled--this is a controlled double-blind
                  study that you've already unblinded and seen the results of?

J. Maraganore:    No, haven't unblinded the trial yet. We are currently at this
                  point stopped enrollment. We still are collecting data as it
                  relates to follow up in patients that are completing their
                  last follow up route.

M. Geller:        Great, thanks a lot.

J. Maraganore:    Thanks, Matt.

Operator:         Your next question comes from David Witzke with CS First
                  Boston. Please go ahead sir.

May Robb:         Hey, it's May Robb and David and we have a few questions. One
                  of the questions related to the financials. In terms of SG&A,
                  SG&A and R&D, you're significantly above [unintelligible] this
                  quarter, so, you know, excluding the impact of acquisition,
                  which definitely wasn't in the numbers here, what are the
                  reasons? Especially on the SG&A line, and would you expect
                  that trend to continue? And also, David has a few questions.

K. Staff:         Yes, thanks. This is Kevin. On the SG&A side, I think you're
                  starting to see the evolution of Millennium's strategy that,
                  prior to the Cor merger, to build some critical mass in our
                  commercial

                                                                   Page 10 of 15


                  area. One of the biggest drivers was us gearing up for a lot
                  of the activities related to 341 on the market side.

                  We also had some significant business expansion over here.
                  We've talked, in the past, about Millennium's growth. From a
                  people and facilities side, we have about 400 thousand square
                  feet that are now under construction at Millennium. Some of
                  that space is now coming on line. And those are really the two
                  primary drivers of the increase in G&A. It's really commercial
                  infrastructure build and then overall build to support the
                  infrastructure operating the company.

                  And so, what you're going to see post-merger with Cor is,
                  we'll be breaking out, as Cor has done traditionally the sales
                  and marketing line separate from G&A. So you'll more modest
                  growth in the traditional G&A and you'll see us making some
                  pretty significant investments over the next 12 to 18 months
                  in building more commercial capabilities, not just focused on
                  Integrilin but really getting ready for 341.

M. Robb:          OK, and David has a few questions.

David Witzke:     Kevin, I had a couple of questions relating to the quarterly
                  break out. The first, the Cam [unintelligible] revenues from
                  the JV[crosstalk].

K. Starr:         Yeah.

D. Witzke:        [Crosstalk] 20, third and fourth quarters, will that be spread
                  out over the year? Or recognized in those quarters?

K. Starr:         We will have--we'll recognize those Cam[unintelligible]
                  payments in the fourth quarter of each year.

D. Witzke:        Both of them? OK.

K. Starr:         And so, remember folks, when we announce that restructuring of
                  that partnership, we will receive three additional payments,
                  in addition to the 20. We'll have received three additional
                  payments of $40 million each, over the next three years.

D. Witzke:        OK, and a couple of other, on the accounting, as far as the
                  share count following the closure, the merger, are we looking
                  at 58 million new shares? Or, is it 78 million?

K.                Starr: No, it's closer to--it's about 56, 55 to 56 million
                  shares, is what we put in our S4. We think we'll be pretty
                  close to that, pretty close to that number in the transaction.
                  But one thing as you know is, depending on what happens with
                  the convertible debt over the year, would add to that share
                  base. But excluding the convertible debt, we've been averaging
                  about a 3 to 4% dilution effect related to normal use of our
                  stock with options, which is pretty standard, actually a
                  little bit below industry average right now.

D. Witzke:        OK, and then finally, the distribution of the $250 million
                  guidance for partnership revenues? How will that look over the
                  quarters?

K. Starr:         Well, I think it'll look like it has been traditionally. We
                  previously weigh that towards the tail end of the year. I
                  think we've come in at a pretty close pattern on that, each of
                  the last two or three years. So, we suspect it will look very
                  similar to that.

D. Witzke:        OK, thank you.

K. Starr:         Thanks David.

M. Robb:          Thanks.

Operator:         Your next question comes from Ellen Lubman, with Robertson
                  Stephens. Please go ahead.

Ellen Lubman:     Thanks. One of my questions was answered. But the other one
                  was, I was just curious as to how, I guess, the development
                  with the Athi [sp] collaboration is coming along? And how will
                  you be using that in the personalized medicine area, and if
                  you are already doing so? Thanks.

M. Levin:         Hi, this is Mark. On the Athi collaboration is coming along
                  very well. Let me just step back and tell you a little bit
                  about what drove that for us. You know, as you know over the
                  last few years, certainly from the day we founded the company,
                  we were very focused on the early stages of the gene in drug
                  discovery, genes, targets and leads. And we built inside our
                  own transcriptional profiling facility, based on our own Nylon
                  [sp] technology.

                  But based on our commitment to move downstream and build a
                  fully integrated company, at the focus inside on things that
                  we can do best and things that cannot be done on the inside,
                  we again have built this facility.

                  Over the last year or so, based on the fact that genes are
                  becoming available, therefore Olivos [sp] are much more
                  important, we've now been convinced that the Athi Metrics
                  technology is the best technology in the industry, for us to
                  really base our transcriptional profiling facility on. So,
                  you're going to see us aggressively, in 2002, replace our own
                  Nylon platform with the Athi platform, and use that across our
                  overall gene discovery, target discovery. We'll use it in
                  Margery [sp] discovery all the way from gene to patient.

                  And we expect to complete most of that transition during the
                  year 2002.

E. Lubman:        Great, thank you.

M. Levin:         OK, thanks.

Operator:         Thank you. Your next question will come from Dennis Harp, with
                  Deutsche Bank. Please go ahead sir.

Dennis Harp:      Thank you. The first question is for Kevin. On your cash
                  balance, what do you expect to earn as far as your interest
                  rate?

K. Starr:         Well, that's a tough one to forecast, Dennis. I wish I had
                  your crystal ball on that one. You know, our overall net
                  interest incumbent in our projections, are factored into that
                  loss profile. There's obviously going to be a little bit of
                  variability. We're probably in the, you know, 4 to 5, or 5.5%
                  range. It depends on, you know, short-long-term yields shape
                  out over the next year.

D. Harp:          The second question is more for Mark, I guess. That is, you're
                  standing by the objective of '04 profitability. Are you able
                  to get there with the Cor acquisition alone? Or, should we be
                  anticipating additional acquisitions, either companies or
                  products that would get you there by '04?

M. Levin:         That's a good question. Again, as we've started, it's break
                  even, plus or minus, by 2004. And we've felt for many years
                  now that it was important, not only to build a strong
                  discovery and development pipeline, but really drive the
                  company to break even and then, eventually over the next few
                  years, very aggressive growth on an annual basis. So '04 is
                  the break-even year, plus or minus.

                  We expect to do that with Integrilin growing as it, the
                  possibilities of 341 entering the marketplace in that time.
                  And also, as you suggest, it's going to be most likely
                  dependent on additional acquisitions of late stage molecules
                  or products on the market today. And that continues to be an
                  ongoing effort of ours. We're looking, but the most likely
                  scenarios are to continue to look in the cardiovascular and
                  oncology areas. Again, late stage molecules, and/or products.

                  It could potentially happen somewhere else, but those are the
                  areas. So look for Integrilin growth, 341 and acquisitions of
                  late molecules and/or products for oncology and
                  cardiovascular.

D. Harp:          Great, and I have one final question. Of the three to four new
                  products to enter the clinic in 2002, what might those be?

M. Levin:         Well, as I mentioned when I went through the overall summary,
                  the actual that we have opportunities across the entire
                  pipeline. If you remember, I mentioned our goal for '01 was
                  the end of the year, with 12 late stage molecules or
                  pre-clinical candidates. We ended the year with 13. So, it
                  could come out of those 13 candidates and those 13 candidates
                  are actually in the cardiovascular area and the oncology area,
                  for the most part. But they also exist in inflammation and
                  metabolic disease. So, they're distributed across all four
                  franchises.

                  So, we enter this year with high confidence about those three
                  to four molecules entering the clinic in 2002.

D. Harp:          And, would you care to say, of those 13, which are the top one
                  or two that you think are most promising?

M. Levin:         I wouldn't want to comment on any specific molecule. As you
                  know, [unintelligible] for pre-clinical [unintelligible]
                  candidates do occur. And we really don't want to say it's this
                  particular molecule, or this particular molecule. We have lots
                  of opportunities. We're certainly excited about all of them.
                  So, I think it's better to say that we've got 13 candidates in
                  front of us and we think we will certainly hit the three to
                  four this year.

                  And I think more importantly, if you remember, I said by the
                  year 2005, based on the discovery pipeline we see in front of
                  us, we will be delivering five-plus molecules to the clinic
                  every year, forever, essentially. And that's something I think
                  is really very important to consider, because no other company
                  in biotechnology does that today.

D. Harp:          Great. Thank you very much.

M. Levin:         Thanks.

Operator:         Your next question will come from Caroline Pratt, with
                  Needham. Please go ahead.

Caroline Pratt:   Hi everybody. My question is, can somebody talk about the RTK
                  program beyond Flip 3? What therapeutic areas are you looking
                  at, and specifically, maybe, what compounds?

J. Maraganore:    Sure Caroline, this is John. We have a very [unintelligible]
                  rich pipeline behind RTK, and Vaughn should certainly chime in
                  here. It builds off of the receptor Tyrosine Kinase work that
                  has been going on at Cor for many, many years. It also
                  synergizes very nicely with the Kinase work that's been going
                  on at Millennium, for quite some time.

                  And, as we look in front of us now, we clearly with CT53518
                  have got a program with a filed I&D, we expect that to head to
                  the clinic shortly, and that's going to be the lead molecule,
                  and

                                                                   Page 13 of 15


                  that's FLID3 Lygan, which as you know is genetically modified
                  in patients with acute myeloid leukemia, and represents almost
                  a glivet [sp] like strategy for intervening in that disease.

                  Behind that we've got a program, 608, which is a backup
                  program with some attributes that we think might make it
                  suited for diseases like glyoblastoma, this includes ability
                  of that molecule to penetrate the blood brain barrier. And
                  then we think there are opportunities even beyond that with
                  agents that are more targeted toward the MGF receptor in
                  settings such as fibrosis and restenosis. So we think that, we
                  look at this across in fact, three of our franchises, so we're
                  covering cardiovascular, inflammation and oncology with this
                  whole platform of receptor tyrosine kinases, and obviously can
                  build off of that in a very significant way.

M. Levin:         Hey John, this is Mark. What's also exciting about this, and
                  John was getting to that, is that the expertise in kinases in
                  general expands across now the merged company. We've
                  identified over 100 novel kinases at Millennium. COR has been
                  doing chemistry in the overall kinase area; we're doing
                  chemistry in the kinase area. We just formed a relationship
                  with Structural Genomics in the overall structural area to
                  look at kinase structure. We're building up our own group
                  inside. So overall receptor tyrosine kinase's internal
                  tyrosine kinases, the structural chemistry around that is
                  really going to drive this across all of our franchises.

V. Killian:       And this is Vaughn, just to tag on to what John said, this is
                  one of the hidden reasons we were so excited about this
                  merger, that there is a lot more commonality of biological
                  interest between the two companies that most people recognize.
                  But we recognized the minute we started talking with Mark and
                  the rest of the scientists here at Millennium.

Woman:            Great, thank you.

M. Levin:         Thanks Carol.

Operator:         Your next question will come from Jeff Meacham with UBS
                  Warburg; please go ahead.

Jeff Meacham:     Hi guys, good afternoon.

M. Levin:         Good afternoon.

J. Meacham:       Could you update us on the status of the oral 2B3 inhibitor?
                  Are you guys going to go forward with this program, or are you
                  instead focusing more on Integrilin for indications?

V. Killian:       This is Vaughn. As you know the oral 2B3A program is one
                  that's been plagued by misfortune on the part of all the
                  competitive products. The only product out there beside
                  karmafiban [sp] is a product from Dupont/Merck that is now
                  part of the BMS collaboration. We've been waiting to see the
                  results of their phase three trial before we even recommended
                  to Millennium that they invest in that program. Clearly until
                  you see that its hard to proceed down this path. And looking
                  at the rich pipeline that Mark has already described for you,
                  and John started to describe, we think that until there's
                  clear evidence that we might have a significant opportunity
                  here, we're much better off allocating resources elsewhere.
                  But the product is still there, still available and can be
                  moved forward very rapidly.

J. Meacham:       OK. And I guess a question for John, could you also update us
                  on the status of MLN977? You said that we'll see data this
                  year?

J. Maraganore:    Yes, that's our program in asthma. This is a small molecule
                  drawn that's targeting fibro glysoginase [sp] which is a
                  central pathway in the generation of proto-inflammatory
                  leucotwains [sp]. We have an oral program that's in phase two,
                  we also have an inhaled program that we're

                  developing, because we've seen some very strong data regarding
                  the ability of providing topical delivery of this drug, to
                  have a more significant anti-inflammatory affect. We will be
                  completing enrollment of our phase two program over the first
                  half of the year, and will be reporting our results this year
                  as well.

J. Meacham:       Any indication as to the end points of the trial, or the
                  number of patients?

J. Maraganore:    Sure. The program is enrolling across multiple centers, up to
                  300 patients. We have, as a primary end point of the study;
                  we're looking at FEV1. It's a multi-dose study, so we're
                  looking at multiple doses of the drug, we're looking at the
                  effects on FEV1, which is a primary end point in many asthma
                  studies, and we are also looking at secondary endpoints as it
                  relates to other symptoms of asthma, like nocturnal symptoms.

J. Meacham:       OK, great, thanks.

Operator:         Your next question will come from Anna Kazanchyan with
                  Wachovia Securities; please go ahead.

Anna Kazanchyan:  How are you?

M. Levin:         Hi, how are you?

A. Kazanchyan:    Fine, thank you. Several of my questions have already been
                  answered, but I have just two additional questions. You did
                  mention that you intend to grow through M&A during this year
                  and going forward. Could you provide us a little more color on
                  that as far as are you looking more to acquire companies
                  versus product, and if you are looking to acquire companies,
                  how do you plan to deal with explosive growth that may result?
                  And secondly, now that you have the fourth franchise, the
                  cardiovascular franchise, I assume you also will be looking at
                  cardiovascular compounds and companies, but overall it has
                  been my impression that these trials require more prolonged
                  follow up and are generally enrolling more patients, they are
                  more expensive than some of the cancer trials that one can
                  conduct. In light of that I'm wondering if the R&D estimate
                  for next year is a little bit more conservative than it should
                  be? Thank you.

M. Levin:         OK, good questions. Let me just kind of give you a little
                  color on that, as you suggested. One of the important things
                  to think about is when you're building, as we are, the next
                  major biopharmaceutical company, is that certainly you want to
                  drive it internally, but you want to complement it with
                  expertise, technologies and certainly molecules and products
                  from the outside. And we had a board meeting, which we've
                  talked about many times before, a little over three years ago,
                  where we said, lets drive the company from the inside, but
                  lets complement it with expertise and with molecules from the
                  outside.

                  And if you look back at the history of the entire
                  pharmaceutical industry, not just over the last couple of
                  years, but if you look at Pfizer and the Merck's and all the
                  major pharmaceutical companies, 30 and 40 and 50 and 60 years
                  ago, they were all built by bringing important companies
                  together, again not just over the last couple of years. So
                  that's been a Millennium premise, in order to build a major
                  company, bring assets together. So where are we today? Well,
                  we do have a major effort in this whole area. We have a team
                  in place; the team is continuously evaluating what we believe
                  to be the major most important companies in the industry. We
                  are also evaluating all the pipelines of the major companies,
                  and certainly evaluating a lot of the pipelines of the major
                  pharmaceutical companies.

                  These discussions are ongoing every week, we have a
                  significant meeting every Monday night where we review all the
                  data, and it's tied into an overall value creation model that
                  we're driving the company on, building a major pharmaceutical
                  company over the next 10 years. So where are

                  we focused today? We're focused certainly on cardiovascular
                  area and the oncology area, as I said before. We're looking
                  for late stage molecules and/or products on that market.
                  That's the driving force today. I should tell you that it
                  doesn't have to occur this month or six months from now, or
                  twelve months from now, its based on the quality and the match
                  of the people and the products, and they will occur at the
                  appropriate time. A big part of this overall strategy is
                  continuous evaluation, continuously talking to the best people
                  in the industry, and then the appropriate opportunity. Because
                  if you're not talking all the time, you will miss a lot of
                  important opportunities. So focus is cardiovascular and
                  oncology, and we believe that's certainly going to be key in
                  breaking even in '04 and building a major company over the
                  next eight to ten years. Does that answer your first question?

A. Kazanchyan:    Yes, thank you.

M. Levin:         OK, thanks. Hello?
