 PRESENTATION

Operator

  Welcome  to  the  Quest  Diagnostics   investor  conference  call.   (OPERATOR
INSTRUCTIONS).  Now I would like to  introduce  Laure Park,  Vice  President  of
Investor Relations for Quest Diagnostics.




- --------------------------------------------------------------------------------
 Laure Park  - Quest Diagnostics - VP, IR

  Thank you for joining us. I am here with Surya  Mohapatra,  Chairman and Chief
Executive Officer of Quest Diagnostics.  We are also joined by Bob Hagemann, our
Chief Financial Officer, and Tom Grant, LabOne's Chairman and CEO. Surya and Tom
will  make a few  brief  remarks  on our  news so that we can get  right to your
questions.

As you know,  LabOne issued its financial  results this morning.  This call will
focus on Quest Diagnostics'  agreement to acquire LabOne. As such we will not be
commenting on LabOne's financial results.  LabOne has canceled its earnings call
for today and plans to file its  second-quarter  10-Q  before the  market  opens
tomorrow  morning.  The terms of this agreement are summarized in this morning's
press  release in the merger  agreement we filed earlier today as part of a Form
8-K.

Some of our  commentary  and answers to  questions  may contain  forward-looking
statements  that  are  based on  current  expectations  and  involve  risks  and
uncertainties  that could cause  actual  results and  outcomes to be  materially
different.  Certain of these risks and  uncertainties are described in the Quest
Diagnostics and LabOne 2004 Forms 10-K, subsequent filings and the press release
related to this transaction issued earlier today. Now here is Surya Mohapatra.

- --------------------------------------------------------------------------------
 Surya Mohapatra  - Quest Diagnostics - Chairman & CEO

  Thank you. I'm excited to announce that we have signed a definitive  agreement
to acquire LabOne in a cash  transaction  valued at $934 million.  We expect the
transaction  will close during the fourth  quarter of 2005.  LabOne is a leading
provider of clinical  diagnostic  testing and drugs of abuse  testing and is the
leader in the health  screening  and risk  assessment  (inaudible)  for the life
insurance industry.

LabOne  operates major modern  laboratories  in Lenexa,  Kansas and  Cincinnati,
Ohio.  It also has a  state-of-the-art  call  center  in  Summit,  Missouri  and
provides  pharmacological  examination services throughout the United States and
Canada to solve the life  insurance  industry.  Our companies  have  contributed
services and facilities.  LabOne operates on a national scale but with a limited
infrastructure. Quest Diagnostics' extensive network infrastructure and our many
other  core  capabilities  will  accelerate  LabOne's  growth  and  improve  its
profitability.

I  anticipate   that  the  acquisition   will  generate   annual   synergies  of
approximately  $30  million.  This  acquisition  will  solidify  our  leadership
position in diagnostic  testing by expanding  access for physicians and patients
and giving us added presence in several geographic areas, and it will expand our
position as the nation's leader in drug of drugs of abuse testing.

In  addition,  this will  establish  us as the  leader in a new  testing-related
business, providing health (inaudible) services to the life insurance industry.

I'm pleased that Tom Grant will join Quest Diagnostics  reporting directly to me
and lead the combined  business,  (inaudible)  the life  insurance  industry and
employers. We look forward to bringing together two companies that are dedicated
to quality, service and (inaudible).

Combining our two companies will significantly  enhance customer service for the
health care  providers  and  patients.  LabOne's  customers  will  benefit  from
improved access to Quest Diagnostic' network of laboratories, approximately 2000
patient  service  centers and strong  logistic  capabilities.  LabOne's  present
customers will have an expanded  testing menu, as well as access to consultation
with the industry's leading network of medical and scientific specialists.  They
will also have access to Quest Diagnostics'  (inaudible) portal. It enables them
to order tests and view results online, as well as create electronic (inaudible)
systems.




Employees and customers will benefit from access to infrastructure  and expanded
testing  options,  including  hair  testing and expanded  wellness  products and
services such as our Blueprint for Wellness.

Now it is my pleasure to introduce Tom Grant.

- --------------------------------------------------------------------------------
 Tom Grant  - LabOne - Chairman & CEO

  Thank you. Good morning,  everybody. I believe this is an exciting opportunity
for  LabOne  and an  attractive  offer for LabOne  shareholders.  Our  physician
customers will benefit from expanded access to lab services.  In addition,  they
will have access to the advanced  science and medicine  offered  through Nichols
Institute,  Quest  Diagnostics  esoteric  testing  laboratory  and  research and
development center, as well as consultation with more than 400 MDs and PhDs.

Personally I am thrilled to be joining a company focused on patients, growth and
people with strong  vision and values.  I am excited  about leading the combined
risk assessment and employer businesses. I'm proud of the strong track record we
have  established  at  LabOne  as a  result  of the hard  work of our  dedicated
employees who will now become part of the industry leader.

Quest  Diagnostics and LabOne will  complement each other.  Our strengths in the
clinical  testing market enable Quest  Diagnostics to expand its reach,  and I'm
excited about the opportunity to use Quest Diagnostics' distribution network and
many  other  capabilities  to further  differentiate  ourselves  as the  leading
provider to the life insurance industry. This will accelerate growth and improve
profitability of the LabOne business.

- --------------------------------------------------------------------------------
 Surya Mohapatra  - Quest Diagnostics - Chairman & CEO

  Thanks,  Tom. As you know,  we have  demonstrated  our ability to  effectively
integrate companies.  We will use our proven integrated approach that has served
us so well through  previous  acquisitions.  We anticipate  that the (inaudible)
will drive revenue growth and generate significant synergies.

The  biggest  contributor  to  the  synergies  will  be  eliminating   duplicate
infrastructure  and  administrative  and public company costs.  And  integration
(inaudible)  will be  established  with  members  from  both  companies.  We are
building a strong foundation to deliver sustainable  profitable growth, and this
acquisition is an important element of our plan.

Operator, we will now take questions.



 QUESTION AND ANSWER


- --------------------------------------------------------------------------------
Operator

 (OPERATOR INSTRUCTIONS). Tom Gallucci, Merrill Lynch.

- --------------------------------------------------------------------------------
 Tom Gallucci  - Merrill Lynch - Analyst

  I just had two questions if I could.  First, I was wondering  you'll get a new
line of business here in the risk  assessment  area.  Can you just maybe give us
some  thoughts on how you are viewing that  business  longer-term  as Quest gets
into it initially here?




And then the other  question  was, it is a cash deal. I was just  wondering  how
that came  about.  Obviously  Tom will be taking  on a new  position  at the new
company,  so he will continue to have his  incentives  aligned with the Company.
But can you talk about the cash versus a stock deal?

- --------------------------------------------------------------------------------
 Surya Mohapatra  - Quest Diagnostics - Chairman & CEO

  Thank you,  Tom. We are very excited about this  acquisition.  As you know, we
have been signing our  double-digit  growth for two  elements,  the  acquisition
growth that  (inaudible)  growth and organic  growth.  In organic growth for the
last 18  months,  we have been  focused  on how to make the  Company -- take the
Company from solid (inaudible) into sales and science, and we have done a number
of strategic alliances over the last 18 months to establish our organic growth.

When it  comes  to  acquisition  growth,  this  particular  acquisition  is very
important because we are getting into testing (inaudible) business,  which is an
addition to our space. For example,  we believe as people are getting older, the
life  insurance  is  getting  more and more  dependent  on not only  just  their
laboratory  testing but also  paramedical  services.  And LabOne is easily doing
this test. It's $1 billion market, and they have only $250 million.

- --------------------------------------------------------------------------------
 Tom Grant  - LabOne - Chairman & CEO

  260 actually.

- --------------------------------------------------------------------------------
 Surya Mohapatra  - Quest Diagnostics - Chairman & CEO

  260.  And we have  plenty  of  room  to  grow.  The  key  here  is that  Quest
Diagnostics is going to bring a lot of core competencies  which will really help
and accelerate the growth of the insurance business.

Tom, do you want to add anything?

- --------------------------------------------------------------------------------
 Tom Grant  - LabOne - Chairman & CEO

  Yes,  absolutely.  We are very excited about our new  relationship  with Quest
Diagnostics  and  being  part of the  team,  and we think to the life  insurance
industry  bringing  access to a Company  that has over 400 MDs,  many many PhDs,
will be terrific  because  certainly  the life  insurance  industry is using the
laboratory  testing  really -- as really a means to evaluate the risk and having
access to new tests that are developed is of keen interest to the life insurance
industry.

In addition with all of the patient service  centers that Quest  Diagnostics has
around the country,  we think that there is some opportunity  there as well with
some of the paramedical examinations, and we also think with -- although this is
not part of the risk assessment business, two of really the engines that we have
built with our risk assessment  business,  the paramedical business now where we
have over 5000 mobile  phlebotomists  around the country,  the Quest Diagnostics
has a product called Blueprint for Wellness,  and we are extremely excited about
the opportunities for Blueprint for Wellness,  utilizing our mobile  paramedical
network and also  utilizing  our call center  that we  mentioned  earlier and at
least some where we can use  individuals  that are now doing medical  histories,
and they can function really as health counselors for behavior modification.

- --------------------------------------------------------------------------------
 Surya Mohapatra  - Quest Diagnostics - Chairman & CEO




 Bob, would you confirm (inaudible)?

- --------------------------------------------------------------------------------
 Bob Hagemann  - Quest Diagnostics - CFO

  Tom, this is Bob Hagemann. You have heard me consistently say that we generate
a lot of cash,  and our first priority for that cash is to deploy it into growth
opportunities. And this is -- we believe an ideal opportunity for that.

When you think about cash versus stock,  we believe that  utilizing  cash versus
stock is also going to generate  better returns for our  shareholders  given the
cash flow characteristics of our business.

- --------------------------------------------------------------------------------
Operator

  Ricky Goldwasser, UBS.

- --------------------------------------------------------------------------------
 Ricky Goldwasser  - UBS - Analyst

  Good morning.  It seems like LabOne has been for sale for a few years now. And
obviously the added Health  Alliance to the books  business,  which is a greater
explosion  to clinical  testing,  but can you tell us what is  different in your
operating environment today compared to a year ago, two years ago that makes you
decide that you actually want to go ahead with that transaction?

And then the second question is actually relating to Health Alliance.  They made
a decision to go ahead with  LabOne at a time  rather  than one of the  national
players,  and just wondering if there any provisions that would allow the Health
Alliance network to separate themselves in the out years?

- --------------------------------------------------------------------------------
 Surya Mohapatra  - Quest Diagnostics - Chairman & CEO

  Tom?

- --------------------------------------------------------------------------------
 Tom Grant  - LabOne - Chairman & CEO

  Yes,  absolutely.  First,  let me  comment on I think you  mentioned  that the
Company was for sale,  and LabOne was not for sale. We had an  unsolicited  cash
offer for the Company,  and we  certainly  had no  discussions  at any time with
anybody about selling our Company.

Regarding the Health Alliance  situation,  we had built a brand-new  facility in
the Cincinnati area which is dedicated to serving the needs of the physicians in
the Cincinnati  community and certainly the Health Alliance system.  We are very
confident of the  relationship  that we have with the folks at Health  Alliance,
and I know -- as a matter of fact, I think Quest had some  discussions  with the
Health Alliance people as well in the dialogue as they looked to outsource their
laboratory.

- --------------------------------------------------------------------------------
 Ricky Goldwasser  - UBS - Analyst

  So it is part of the due  diligence  process  Quest  talked  with  the  Health
Alliance  people and there are no  provisions  that two or three  years from now
might cause the separation of the business?




- --------------------------------------------------------------------------------
 Bob Hagemann  - Quest Diagnostics - CFO

  As you would expect, we thoroughly  reviewed all of the significant  contracts
that LabOne has,  this one  included,  and we feel very  comfortable  about that
relationship.

- --------------------------------------------------------------------------------
 Surya Mohapatra  - Quest Diagnostics - Chairman & CEO

  As you know,  we have been  driving our strategy  based on patient  growth and
people,  and when we look at LabOne,  our goal was just not to buy a laboratory,
but also to meet our three key drivers of our growth.  To solidify  our position
in radio geographic  areas where we have been working.  The second thing is that
it gives us a new market which we want to bring our core  competencies  and help
LabOne  because  they  are the  leader,  but  when  you put  Quest  Diagnostics,
information  technology  Quest  Diagnostics  (inaudible)  and Quest  Diagnostics
science and  medicine,  it really opens up a lot of  opportunity  for us for the
employer business and also for the insurance business, and this will also become
the platform for our  wellness  products.  So I'm very excited that by combining
these two companies not only we are driving the top line,  but also it makes the
LabOne  business  much  more  profitable,  and it  helps us to  really  meet our
strategic goal also.

- --------------------------------------------------------------------------------
Operator

 Gary Lieberman, Morgan Stanley.

- --------------------------------------------------------------------------------
 Gary Lieberman  - Morgan Stanley - Analyst

  Maybe just to  follow-up a little bit on the last  question  that was asked in
terms of specifically  or just generally,  what has changed now to make this the
right deal versus pursuing this, say, a year ago?

- --------------------------------------------------------------------------------
 Tom Grant  - LabOne - Chairman & CEO

  Again,  we had no  dialogue  with  anybody a year  ago,  and this is Tom Grant
talking  now.  We never had  dialogue  with  anybody  regarding  the sale of our
Company before Quest approached us.

- --------------------------------------------------------------------------------
 Gary Lieberman  - Morgan Stanley - Analyst

  I just directed more toward Surya. From your perspective, what makes this deal
a good deal for you now versus trying to get it done previously?

- --------------------------------------------------------------------------------
 Surya Mohapatra  - Quest Diagnostics - Chairman & CEO

  Well,  first of all,  as I told you that  when I came to see you,  I wanted to
make sure that we can really grow  internally,  and organic growth was extremely
important  for us,  so we  worked  extremely  hard to set our  improving  sales,
improving service and really setting up a lot of strategic alliances as you have
seen over the last  three or four  months.  We signed  up with  three  different
companies in proteomics.




So  having  the  organic  growth  going  and  making  sure that we have a strong
foundation  and  at  the  same  time  we  have  been  looking  for a  number  of
opportunities,  and frankly, a number of opportunities  which we saw were passed
because it did not meet our strategic  goals,  and the  strategic  goal was very
simple. It has to be a well-run company. It has attractive sort of growth, it is
strategic for our future,  and at the same time, it makes economic sense.  And I
am the person who really approached Tom, and it has been really a combination of
desire and will to make this thing happen rather than anything else.

- --------------------------------------------------------------------------------
 Tom Grant  - LabOne - Chairman & CEO

  And Gary,  you have many  add-ons to that and address  what you and Ricky were
asking.  There is nothing  specific that has changed.  Anytime you're looking at
acquisitions,  particularly  one of this size,  it is a  combination  of a whole
bunch  of  things  that  need to come  together.  It  needs  to fit in with  our
priorities.  There needs to be a willing buyer,  willing seller. You need to get
the right  valuations,  and  sometimes  all those things don't come  together as
quickly  as you  would  like.  In  this  case,  they  did,  and we had a  unique
opportunity here.

- --------------------------------------------------------------------------------
 Gary Lieberman  - Morgan Stanley - Analyst

  And then if I could just ask a quick follow-up, you all on the Quest side have
spoken  historically  about being very  disciplined on the pricing front and the
prices that you would be willing to pay for acquisitions. It would look like the
price that  you're  paying at least on an EBITDA  multiple is  significantly  in
excess of where Quest is trading.  So could you talk a little bit more about the
synergies  that you  think  you're  going to be able to  generate  that make you
comfortable with the price that you are paying?

- --------------------------------------------------------------------------------
 Bob Hagemann  - Quest Diagnostics - CFO

  Gary,  we indicated  that we expect to generate  approximately  $30 million in
synergies  once  the  two  companies  are  fully  integrated,  and we  are  very
comfortable  with that number.  They are going to come from the typical areas --
corporate overhead, public company costs, excess testing capacity and duplicated
infrastructure.  And given the amount of the number of integrations that we have
done over the years,  we can usually get very  comfortable  with a pretty  tight
range of synergies.

When you layer  those  synergies  on to the cash  flows and EBITDA  that  LabOne
generates,  we are paying just over an eight times multiple,  which I think when
you look at that relative to other  transactions that have been done relative to
our multiple, it is very reasonable.

- --------------------------------------------------------------------------------
 Gary Lieberman  - Morgan Stanley - Analyst

  Should we expect  this to be  accretive  in the first  year,  or how should we
think about it from an EPS perspective?

- --------------------------------------------------------------------------------
 Bob Hagemann  - Quest Diagnostics - CFO

  Well,  in '05,  if it does close in '05,  which is what we  expect,  we really
don't expect anything  material at all given how late in the year it is going to
close. So the impact to EPS, excluding any charges that we might have associated
with the  transaction,  will really be  immaterial,  and we're not  anticipating
changing our guidance as a result of that.




  And then in '06, we expect it to be modestly accretive.  As you know, we don't
have any guidance out there for '06 at this point.

And then  certainly  beyond '06, as we integrate the  operations and realize the
full synergies, we would expect the accretion to accelerate beyond that point.

- --------------------------------------------------------------------------------
Operator

 Adam Feinstein, Lehman Brothers.

- --------------------------------------------------------------------------------
 Adam Feinstein  - Lehman Brothers - Analyst

  Just a few  questions.  First,  I  think I know  the  answer.  I just  want to
clarify.  Since you guys have  revenues  coming from many  different  sources at
Quest,  I guess do you have any  revenues  now coming  from the risk  assessment
business? Even if very small, do you any revenues?

- --------------------------------------------------------------------------------
 Bob Hagemann  - Quest Diagnostics - CFO

  No, we do not.

- --------------------------------------------------------------------------------
 Adam Feinstein  - Lehman Brothers - Analyst

  Okay. So no current  revenue.  Okay. Just my second question just to follow-up
to the last couple of  questions.  Just on the  synergies,  can we get some more
details?  Considering  this is a new line of business  than just talk about just
the ability to really consolidate the operations, are you're going to close down
centers?  Where exactly  should we see these changes coming from since this is a
new line of business?

- --------------------------------------------------------------------------------
 Bob Hagemann  - Quest Diagnostics - CFO

  As we said,  Adam,  the  synergies  are going to come from  several  areas.  A
significant  piece will come from  corporate  overhead and total company  costs.
Certainly  excess testing  capacity.  But when you think about the other line of
business, we really have complementary operations. And that is not where we were
expecting a significant amount of synergies to come from.  Actually we're hoping
to use our  resources  and the resources of LabOne in that area to actually grow
and accelerate the growth in the risk assessment business.

- --------------------------------------------------------------------------------
 Adam Feinstein  - Lehman Brothers - Analyst

  Okay.  And then just a question  for LabOne here just in terms of maybe -- Tom
may be the best one to answer this.  But just you were talking before saying you
have international I guess operations versus limited  infrastructure  currently.
So what kept you from I guess really  expanding  the  business  more than in the
past?  Clearly  you guys have shown very  strong  growth  over the last  several
years, but was there anything that kept you from really building out the Company
more previously?

- --------------------------------------------------------------------------------
 Tom Grant  - LabOne - Chairman & CEO




  Yes, I think in terms of when you look at the health care  opportunity,  which
clearly was the greatest  opportunity  for our Company,  you are talking about a
$40  billion  market.  The  reality  is that the bulk of our  business  with our
clinical  businesses in the Midwest and Kansas,  Ohio,  and Missouri and to roll
out on a national basis obviously is an expensive  endeavor,  and certainly that
was an endeavor that we were willing to take on but with the opportunity I think
to really partner to work with Quest  Diagnostics with their national platform I
think,  and  with the  premium  for our  stock,  I think  this is an  attractive
alternative for our shareholders.

- --------------------------------------------------------------------------------
 Adam Feinstein  - Lehman Brothers - Analyst

  Okay.  And  then  just  maybe,  Bob,  just one more  question  if I may.  Just
previously you were talking about stock buyback. How should we think about stock
buyback going forward?  I know the deal is not going to close until later in the
year.  But how are you going to balance that,  and I guess should we think about
you guys  taking on the  incremental  debt,  or do you plan on using all of your
free cash for the deal?

- --------------------------------------------------------------------------------
 Tom Grant  - LabOne - Chairman & CEO

  I think,  as we said in the press release,  we plan to finance the acquisition
through a combination of cash, our available credit facilities, and we will most
likely raise some debt. In doing that,  though,  our credit statistics are still
going  to be  very  conservative,  and I think  it  provides  us with  continued
flexibility  to  pursue  other  acquisitions,  as well as  continue  to do share
repurchases.

- --------------------------------------------------------------------------------
 Adam Feinstein  - Lehman Brothers - Analyst

  But will we see I guess from now until the end of the calendar year, would you
guys not be in the market buying stock most likely?

- --------------------------------------------------------------------------------
 Bob Hagemann  - Quest Diagnostics - CFO

  Since we have not given specific  guidance on the amount of share  repurchases
that we do either for the year or for the quarter,  yes, I really cannot comment
on that.  Other than I am telling you that this  acquisition will not impact our
ability to do share repurchases or other acquisitions.

- --------------------------------------------------------------------------------
Operator

 Steve Hamill, Piper Jaffray.

- --------------------------------------------------------------------------------
 Steve Hamill  - Piper Jaffray - Analyst

  First,  I was  wondering  on the  synergy  front if this deal poses more of an
opportunity to take advantage of excess testing  capacity than perhaps  previous
deals that Quest has done given the large size and  capacity  available  both in
Lenexa and Cincinnati?

- --------------------------------------------------------------------------------
 Bob Hagemann  - Quest Diagnostics - CFO




 I would say that it is not typically any different than others. You know   when
you look at the acquisitions that we have done over the last years whether it be
Unilab or AML, I think you have had similar situations. So I would not cite this
as significantly different one way or another.

- --------------------------------------------------------------------------------
 Steve Hamill  - Piper Jaffray - Analyst

  Okay.  And then I was  wondering if maybe Tom could comment a little bit about
the risk assessment  business.  Obviously you just reported your  second-quarter
results also this morning, and that life insurance market in general looks to be
pretty  soft.  Is this  something  that is  probably  going  to turn in the next
several  quarters,  or is just a long-term  decline in the total life  insurance
market in your view?

- --------------------------------------------------------------------------------
 Tom Grant  - LabOne - Chairman & CEO

  The MIB index,  the Medical  Information  Bureau Index, has the number of life
insurance  applications  up about 5%, and the market this year has been somewhat
soft.  But again as you pointed  out,  Steve,  that market  tends to be somewhat
cyclical, and certainly we would anticipate in the future that there would be --
that there would be a strengthening of that marketplace.

- --------------------------------------------------------------------------------
 Steve Hamill  - Piper Jaffray - Analyst

  And is that something where given this  combination you feel like there is any
improved opportunity to take share, or is it pretty tough given the size of your
market share position already?

- --------------------------------------------------------------------------------
 Tom Grant  - LabOne - Chairman & CEO

  Absolutely.  Want me to answer that? I think there is a tremendous opportunity
to take share.  Certainly as I mentioned  earlier before with the access we have
to the scientific talent at Quest Diagnostics, the laboratory testing is of keen
interest and is really  critical in terms of the  evaluation  of risk. So having
access to new -- whether it is cardiovascular  markers or cancer markers is very
significant to the life insurance industry.

We think it's also significant in that now instead of just one or two facilities
for disaster recovery facilities, there are 35 facilities that Quest Diagnostics
has, which will be of I think of keen interest to the life insurance industry as
well. So numerous advantages.

Also on the  paramedical  side,  we  have  already  talked  about  the  wellness
opportunities.  Certainly to utilize some of the fixed  locations in paramedical
collections  is of  interest  as well.  But we think  that we can get  increased
market share.

- --------------------------------------------------------------------------------
 Surya Mohapatra  - Quest Diagnostics - Chairman & CEO

  I'm not very worried  about whether the market grows every year or not. When I
look at the available market, we are only $261 million in that business, and the
market is up roughly $1 billion.

The key is, how do you really bring these two companies  together and to use the
expertise  whether it is a call center,  whether it is  (inaudible)  technology,
whether it is a present  service center or whether  bringing new tests and doing
the appropriate algorithm to find out risk. And one day as Tom says, people will
have individually tailored life insurance. Right, Tom?




- --------------------------------------------------------------------------------
 Tom Grant  - LabOne - Chairman & CEO

  Absolutely.

- --------------------------------------------------------------------------------
 Surya Mohapatra  - Quest Diagnostics - Chairman & CEO

 So we are pretty excited about the skills and the expertise they bring. Also, I
think some of these services LabOne has, which is paramedical services, can help
also our core business. Because obviously as we get older, some people would not
like to come to PSC (ph), so we're looking at how you really utilize the mobile
paramedics also to help our core business.

- --------------------------------------------------------------------------------
Operator

 Eugenia Shin, Thomas Weisel Partners.

- --------------------------------------------------------------------------------
 Eugenia Shin  - Thomas Weisel Partners - Analyst

  Given your focus on the PSCs and the customer, could you just provide a little
bit more granularity on your plans on using the para-services  organization that
drives this?

- --------------------------------------------------------------------------------
 Surya Mohapatra  - Quest Diagnostics - Chairman & CEO

  Well, I'm going to start with the PSC and the  customers,  and I will have Tom
talk about how the paramedical services can be an extension to our field network
we have. You know we have approximately  2013 service centers,  and we're almost
35 to 38 million people go to the PSC.

And, as you know, we have  approximately  140 million  (inaudible)  encounters a
year.  I think that our  businesses  which we could get if we can have access to
paramedical  services,  and that was  some of the  things  that Tom and I talked
about.  How do you really utilize those services not only for life insurance but
also for core and wellness?

- --------------------------------------------------------------------------------
 Tom Grant  - LabOne - Chairman & CEO

  Absolutely.  I think  Surya  talked a little bit about our mobile  paramedical
network.  We think the opportunities for our mobile  paramedical  network really
are twofold, and then I will comment on the patient service centers.

First,  regarding the  wellness,  I think I mentioned  this earlier.  But we are
incredibly excited about the opportunities for utilizing our paramedical network
to do really help there is wellness testing for large corporations.

Right now in American  business you're looking at over the last four years a 50%
increase  in health  care cost.  Obviously  with the advent of  consumer  driven
health care plans and with consumers  having to take or employees having to take
more  responsibility  for their own  health,  companies  are turning to wellness
programs and turning to health risk appraisals. And the key part of those health
risk appraisals is the biometric data from laboratory testing. And to do testing
on a  large-scale  basis for  large  corporations,  having a mobile  paramedical
network to utilize our people is a tremendous  opportunity  for our  paramedical
company called ExamOne.




Secondly,  as Surya said,  they do millions and  millions of patient  encounters
around the  country,  and  certainly  there could be a small  market in terms of
doing some mobile collections with our network in the clinical setting as well.

And then thirdly,  we do right now -- with our  paramedical  office,  we do some
fixed site location  collections,  and certainly that  opportunity is there with
the 2000 patient service centers that we have talked about.

 Eugenia Shin  - Thomas Weisel Partners - Analyst

  Great.  And then the traditional lab attrition rate is about 15 to 20%. Do you
think given your mix that you will be seeing a lower rate?

- --------------------------------------------------------------------------------
 Surya Mohapatra  - Quest Diagnostics - Chairman & CEO

  I did not -- what did you say?

- --------------------------------------------------------------------------------
 Bob Hagemann  - Quest Diagnostics - CFO

  Where did you get your numbers on lab attrition rate? Are you talking customer
turnover?

- --------------------------------------------------------------------------------
 Eugenia Shin  - Thomas Weisel Partners - Analyst

  Yes.

- --------------------------------------------------------------------------------
 Bob Hagemann  - Quest Diagnostics - CFO

  I'm not sure that that is a good number. And, frankly, we have never disclosed
what our attrition rate is, but it is certainly well south of 15%.

 John Wood  - Bank of America - Analyst

  John Wood in for Bob. There is about a 10 day differential in the DSOs between
the  businesses.  Is that a structural or mix issue?  Can you talk about some of
the initiatives that Quest can employ to drive that down?

- --------------------------------------------------------------------------------
 Bob Hagemann  - Quest Diagnostics - CFO

  Certainly I think there are some opportunities there to drive down DSOs on the
LabOne  side.  Some of it is  structural,  though,  in  terms  of  their  mix of
business.  But certainly we will be looking to take all of our



best  practices  in the billing  operation  and see if we can  utilize  those in
LabOne's operations. Their bad debt, keep in mind, is very low already, and that
is driven by a mix of business.  So on one hand, you might have slightly  higher
DSOs. On the other hand, you have much lower bad debt.

- --------------------------------------------------------------------------------
 John Wood  - Bank of America - Analyst

  Can you characterize LabOne's esoteric  capabilities?  Is that an area that we
need to be focused on for the revenue synergies moving forward, especially given
their presence in the hospital market?

- --------------------------------------------------------------------------------
 Surya Mohapatra  - Quest Diagnostics - Chairman & CEO

  Tom, do you want to comment on this?

- --------------------------------------------------------------------------------
 Tom Grant  - LabOne - Chairman & CEO

  Yes,  actually the esoteric testing for us is a very small amount of work that
we are doing for  hospitals.  We have  brought more and more tests  in-house.  I
think this is an opportunity Surya can comment on as far as the esoteric during.

- --------------------------------------------------------------------------------
 Surya Mohapatra  - Quest Diagnostics - Chairman & CEO

  Yes. You know, one of the synergies and one of the  opportunities we think the
LabOne  customers are going to get, they will have access to Nichols  Institute.
And whatever they outsource  (inaudible) it will come to Nichols  Institute.  So
that is an  opportunity  there  both from a synergy  point of view and also both
from the doctors and patients having access to this large menu.

- --------------------------------------------------------------------------------
 John Wood  - Bank of America - Analyst

  Great  and  then  one  more.  Bob,  do you  have a  preliminary  estimate  for
intangibles on the deal?

- --------------------------------------------------------------------------------
 Bob Hagemann  - Quest Diagnostics - CFO

  We have some ranges at this point. I'm not prepared to disclose anything,  but
it has been factored into the  estimates  that we have provided to date.  What I
would tell you is yes, we have run some pretty significant  sensitivities around
that, and despite where we come out within that range, it is not going to impact
our views of the accretion associated with the transaction all that much.

- --------------------------------------------------------------------------------

 Kemp Dolliver, SG Cowen Company.

- --------------------------------------------------------------------------------
 Kemp Dolliver  - SG Cowen Company - Analyst

  Two sets of questions.  First,  and, Bob, you may have cutoff this  discussion
for the  moment,  just any  further  details  you can give with  regards to your
assumptions for 2006 in terms of the accretion,  whether




it is the  percentage  of the  synergies you think you would realize in '06? And
again,  back to the earlier  question about  intangibles  and also net borrowing
costs. Thank you.

- --------------------------------------------------------------------------------
 Bob Hagemann  - Quest Diagnostics - CFO

  It sounds like there were three of them there.

- --------------------------------------------------------------------------------
 Kemp Dolliver  - SG Cowen Company - Analyst

  Sorry about that.

- --------------------------------------------------------------------------------
 Bob Hagemann  - Quest Diagnostics - CFO

  That is okay.  As I said  earlier,  we have not provided  guidance for 2006 at
this  point.  In 2006,  though,  we do  expect  to start  realizing  some of the
synergies  associated  with this  transaction.  We will  also  have  some  costs
associated  with  integrating  the two  operations as well.  But even the net of
those,  we are expecting  will be modestly  accretive in '06. As I said earlier,
once the integration is fully complete, we would expect that the accretion would
accelerate beyond '06.

And as far as the  intangibles  go, yes, I indicated that we are not prepared to
identify how much was specifically allocating to the intangibles.  We still have
some work to do there, but certainly we have run a number of sensitivities,  and
I think we have got the whole spectrum of outcomes  there.  And that within that
spectrum  of  outcomes,  we are very  comfortable  that the  numbers  that we're
putting forth here still hold.

And then on the cost of financing,  I think was your last question,  it is going
to be a mix, quite frankly. Because we will be using some cash. We will be using
some existing credit  facilities  which are LIBOR-based and carry relatively low
grades.  And then we would be  expecting  to go out and raise  some money in the
bond market as well.

- --------------------------------------------------------------------------------
 Kemp Dolliver  - SG Cowen Company - Analyst

  That is fine.  Just one detailed  question on the  synergies is, what kinds of
actions do you think you will be able to take in 2006 to realize  the  synergies
and which actions come later?

- --------------------------------------------------------------------------------
 Bob Hagemann  - Quest Diagnostics - CFO

  Well, I think  certainly the public  company and corporate  overhead costs are
the first  things  that you can get at,  and we will be  getting  at those  very
quickly.  I  think  when  you are  looking  at  excess  capacity  and  duplicate
infrastructure,  some of those  things  take  systems to get  converted  and get
standardized  before you can really realize the full benefits of those. So those
are the type things that come later down the line.

  Congratulations on your transaction.  Just a quick question with regard to the
8-K filing just made. It appears that there is a  divestiture  cap of about 2.5%
of LabOne revenues.  And I was just wondering if there is any particular  reason
you selected that amount? Is there any area of divestitures you think that would
be  required,  or is  that  just  a  number  that  makes  the  transaction  work
financially?

- --------------------------------------------------------------------------------
 Bob Hagemann  - Quest Diagnostics - CFO

  It is a  negotiated  amount  between  the two  parties.  There  we  feel  very
comfortable that from a regulatory  standpoint this will receive full clearance,
and we are expecting to make our filings within the next several weeks.

- --------------------------------------------------------------------------------
 Sam Sabak  - Quattro Global Capital - Analyst

  Okay.  And what impact,  if any,  will this change of control have on LabOne's
State Farm contract?

- --------------------------------------------------------------------------------
 Tom Grant  - LabOne - Chairman & CEO

  We are actually very  confident that this will enhance our  relationship  with
State  Farm.  Because  having  a  relationship  and  being  part  of  the  Quest
Diagnostics  team will  only  strengthen  the  partnership  with the State  Farm
Insurance Company for reasons that I have articulated earlier.

  Congratulations  on the deal. Just a follow-up on the antitrust.  What are the
LabOne revenues in Kansas City and Ohio?

- --------------------------------------------------------------------------------
 Bob Hagemann  - Quest Diagnostics - CFO

  I don't believe we have disclosed revenues in any particular geography, and it
has been our practice  not do disclose  revenues by business  unit,  and I would
expect that we would continue that.

- --------------------------------------------------------------------------------
 Edward Genis  - Tidderman (ph) - Analyst

  Are there any local markets here where the two businesses overlap?




- --------------------------------------------------------------------------------
 Bob Hagemann  - Quest Diagnostics - CFO

  Certainly  there is overlap in many of the markets,  but as we said,  we fully
expect to receive regulatory clearance.

- --------------------------------------------------------------------------------
Operator

 Frank Bianco (ph), McMann Securities.

- --------------------------------------------------------------------------------
 Frank Bianco  - McMann Securities - Analyst

  Two questions.  The first is, do you see any antitrust issues?  And the second
relates to the converts. It looks like the payment date is the 15th of December.
If you convert prior to then, are you still entitled to your coupon?

- --------------------------------------------------------------------------------
 Bob Hagemann  - Quest Diagnostics - CFO

  Let me try and respond to the FTC. Earlier we said we fully expect  regulatory
clearance.  We do not anticipate any issues with this  transaction.  Although we
operate in similar markets,  there is no significant overlap in any of them, and
we will be filing our HSR filings within the next several weeks.

And then with respect to the convert,  I think it is a document that is publicly
filed. When you look at it, you will see that there is a premium associated with
it, and we have  factored that into the cost of the  transaction  for us, and we
are  expecting  that to convert.  We will  essentially  consume  about 3 million
shares and translate into about $132 million in costs.
