Coordinator       Stewart Lawrence, sir, you may begin when ready.

S. Lawrence       Thank you, Todd.  Thanks for joining us this morning,
                  everybody.  As Todd said, I'm Stewart Lawrence, director of
                  investor relations for MCN Energy Group.  I'm here with
                  MCN's executive vice president and chief financial officer,
                  Lee Dow.  We also have on the line with us DTE Energy's
                  senior vice president of finance and treasurer Dave Meador,
                  who will be available to help answer any questions at the
                  end if needed.

                  Before we get into the discussion I need to remind you that
                  statements included in this conference call that are not
                  historical in nature are forward-looking within the meaning of
                  the Private Securities Litigation Reform Act of 1995. These
                  statements involve certain risks and uncertainties that may
                  cause actual future results to differ materially from those
                  contemplated, projected, estimated, or budged in such
                  forward-looking statements. A discussion of these risks and
                  uncertainties is included in the company's periodic reports
                  filed with the Securities and Exchange Commission.

                                                       MAY 4, 2001/9:00 A.M. CDT
                                                                          PAGE 2


                  I hope by now you've had the opportunity to read through the
                  earnings release issued this morning. The purpose of this call
                  is to review the first quarter results after which we'll
                  entertain your questions.

                  Starting with the earnings review. For the quarter, we
                  reported adjusted income of $63.8 million or $0.71 per diluted
                  share, up slightly from the $0.70 per diluted share in the
                  first quarter of last year. Weather-adjusted, we would have
                  reported $0.76. There was the negative $0.05 per share impact
                  from warmer than normal weather.

                  Consolidated net income came to $43.3 million. That included
                  several cash and non-cash items. On the cash, side the
                  significant item was about $83 million of net gains from asset
                  sales, primarily our coal fines facilities as previously
                  announced. On the non-cash side, we had a cumulative
                  transition charge of about $100.6 million from the adoption of
                  FAS 133, which is the accounting for derivatives and hedges.
                  This charge came in right about where we estimated it would
                  last quarter.

                  Moving on to individual segment results, gas distribution had
                  operating and joint venture income of $164 million, up from
                  $118 million in the 2000 first quarter. These results exclude
                  modest merger costs in both periods. The increase is explained
                  primarily by a $32 million increase in operating profits from
                  the gas sales program as margins rose through the use of low
                  cost gas from storage to meet the program's requirements.

                  Weather also had an impact on the results. While the weather
                  was about 6% warmer than normal, that compares to more than
                  14% warmer than





                                                          MCN ENERGY GROUP, INC.
                                                    MODERATOR:  STEWART LAWRENCE
                                                       MAY 4, 2001/9:00 A.M. CDT
                                                                          PAGE 3


                  normal in last year's first quarter. That's about a $15
                  million improvement in operating income quarter over quarter
                  based on the weather.

                  The pipeline and processing segment had operating and joint
                  venture income of $500,000, down from almost $6 million in
                  last year's first quarter due to the sale of income producing
                  properties as well as lower margins on gathering, processing
                  and methanol production. The lower margins were in line with
                  what we saw in the fourth quarter as we reported at our
                  year-end conference and in line with what we expected to see
                  in early 2001. Not included in this quarter's income number,
                  of course, is the $128 million pretax gain on the sale of our
                  six coal fines facilities. In the electric power segment,
                  asset sales required under the merger agreement brought this
                  segment to about break even on the quarter down from nearly $2
                  million of earnings in the first quarter of 2000. Again, this
                  was in line with the fourth quarter results and our
                  expectations for this year since not much remains within this
                  segment.

                  The E&P segment also suffered from prior year asset sales as a
                  7% drop in production contributed to a decline in operating
                  income, which declined to $3.2 million compared with $4.7
                  million in the 2000 first quarter. This segment has achieved
                  significant operating cost reductions and should report
                  favorably comparable results in future periods.

                  Energy marketing results are difficult to analyze for a number
                  of reasons. As you may recall, a change in accounting for
                  natural gas storage balances beginning in the second quarter
                  of last year makes first quarter





                                                          MCN ENERGY GROUP, INC.
                                                    MODERATOR:  STEWART LAWRENCE
                                                       MAY 4, 2001/9:00 A.M. CDT
                                                                          PAGE 4



                  comparisons next to impossible for the segment. Further
                  complicating things is the first quarter adoption of FAS
                  133, the accounting for derivative instruments and hedging
                  activities.

                  In addition to the cumulative transition charge I talked about
                  earlier, energy marketing got hit with a current period mark
                  to market loss of about $11 million from FAS 133 in the first
                  quarter. This loss is tied to gas sales to power facilities.
                  While we own and produce the gas that supplies these
                  contracts, only the sales contracts themselves and not the
                  physical gas that backs them up gets marked to market. When
                  the futures strip price increases as it did during the first
                  quarter, we report a loss. If the strip decreases we could see
                  that loss get reversed.

                  Similarly, there was about a $5 million loss from marking to
                  market non-hedged natural gas that remained in storage at the
                  end of the quarter. This gas had been marked to more than $10
                  per MCF at year-end, then got marked down to less than $6 at
                  the end of the quarter. On an ongoing basis we shouldn't see
                  such large impacts from this kind of mark to market on hedged
                  gas in storage.

                  Also effecting the quarter was about a $12 million loss as our
                  marketing unit struggled to keep a flat book in a highly
                  volatile market. The problem began in December, which was the
                  coldest on record here in the Midwest, 23% colder than normal.
                  Because of the extreme cold some commercial and industrial
                  customers used significantly more gas than anticipated, which
                  left us in a short position going into January. We bought to
                  cover that short to protect our position in what looked to be
                  a very cold January,






                                                          MCN ENERGY GROUP, INC.
                                                    MODERATOR:  STEWART LAWRENCE
                                                       MAY 4, 2001/9:00 A.M. CDT
                                                                          PAGE 5


                  but then we got hit again since January weather turned out to
                  10% warmer than normal rather than colder as predicted. We
                  were left selling unwanted high cost gas into a plunging
                  market. It's highly unlikely such extreme swings in weather
                  and prices will repeat. At any rate, we're working to reduce
                  our exposure to such phenomenon, so we don't see these losses
                  as an ongoing issue.

                  With that, let me go ahead and turn it over to Lee.

L. Dow            Thank you, Stewart.  First let me recap capital
                  expenditures for the quarter as well as the year's
                  outlook.  For the quarter total expenditures was $35
                  million of which around $20 million of that was in the
                  traditional utility distribution business and about $5
                  million to E&P segment as well as $10 million primarily in
                  our wrapping the Vector construction.

                  For the year we continue to look at our total capital
                  expenditures of $160 million, which we previously discussed as
                  being around $110 million in the distribution and $30 million
                  in E&P and then the other once again primarily in the pipeline
                  segment of $20 million. On a cash basis let me point out again
                  that this is a capital expenditure. It does not include
                  proceeds on sales such as the coal fines in the first quarter
                  as well as to the extent that we are able to sell our out of
                  region assets that don't, long-term, fit into our strategy
                  depending upon prices and our ability to negotiate deals. We
                  of course will continue to pursue the process of selling those
                  assets although not at fire sale pace or price.

                                                    MODERATOR:  STEWART LAWRENCE
                                                       MAY 4, 2001/9:00 A.M. CDT
                                                                          PAGE 6


                  As to the earnings outlook for 2001, other than the nickel
                  impact of weather in the first quarter there was nothing that
                  we discussed for the quarter that would change the guidance we
                  provided on March 7, 2001 of $1.00 to $1.10 per share. Most of
                  the items that Stewart discussed, particularly in energy
                  marketing, relate to accounting issues that we believe we
                  don't know any more about what the price of gas is going to be
                  at year-end 2001 than I did three months ago. A lot of the
                  volatility that we've experienced, nothing about that I
                  believe is sustainable.

                  Now I'd like to close by providing an update on the ongoing
                  status of the long pending merger with DTE Energy. As you
                  know, on May 15th we will have a shareholder meeting to vote
                  on the revised merger agreement. In addition with the filing
                  of the revised U1A on April 27th, we now have a notice period
                  that expires on May 17th with the Securities and Exchange
                  Commission. These now represent the final steps for the merger
                  to close. Assuming prompt action by the SEC, we expect to be
                  able to close by or near the end of May. We at MCN look
                  forward to finally uniting with DTE Energy to form the
                  integrated energy company that has an exciting future here in
                  the Midwest.

                  With that, I will turn it over to Todd so that we can open it
                  up for any questions.

Coordinator       Thank you.  Our first question comes from David Frank of
                  Zimmer Lukas Partners.

D. Frank          I just wanted to ask if you could go over the marketing
                  segment again, some of those costs that were involved.  You
                  said there was a $12 million loss from volatility.  You
                  were short gas early.  You went out to buy gas.  You then
                  sold it at a loss later.

S. Lawrence       Right.

D. Frank          Is this marketing for customers that had signed on a choice
                  program that will fall off at the end of this year?

S. Lawrence       No.  That has absolutely nothing to do with the choice
                  program within the gas distribution segment.  This is the
                  non-regulated energy marketing business, which sells
                  bundled gas services to commercial and industrial
                  customers.

D. Frank          Just out of curiosity if you decided tomorrow that you no
                  longer wanted to participate in gas marketing could you close
                  it down or do you have contracts that go out for some
                  specified time period?

L. Dow            We have contracts that go out particularly with storage and
                  transportation contracts, so we would have those costs.  We
                  wouldn't want to close it down because we think long-term
                  there's value associated with the marketing business, but
                  it is one that we have built assets around.  I will
                  emphasize, however, that this is an example in which the
                  conservative policies of trying to maintain a flat book in
                  the trading business has in fact hurt us by creating shorts
                  and longs that I think a more actively managed and traded
                  portfolio would have been more successful.  I think this is
                  one

                  area we believe that will have a revenue synergy in a post
                  merger environment.

D. Frank          Could you just go over again the other charges?  I think
                  you said you had $11 million mark to market losses and
                  that's based on the strips, not the actual gas price that
                  you had experienced.  Then there's another charge.  I
                  didn't get the amount for marking gas inventory to market.

S. Lawrence       Yes.  David, the $11 million associated with gas sales
                  contracts to power facilities.  These are contracts we
                  entered into a long time ago that were backed up by our
                  production from our Michigan properties.  We've got
                  production to serve these gas contracts.  The problem with
                  FAS 133 is that the owned gas that we have that is
                  supplying the contracts doesn't get marked up or down based
                  on current prices.  The sales contracts themselves do get
                  marked up or down.  In this case because the period over
                  which these contracts are in effect saw increased overall
                  average prices then those sales contracts were considered
                  that much farther out of the money and we took that hit.
                  Again, that's strictly an accounting issue.  The gas is
                  there to back it up.

L. Dow            On that point we believe there is likely a way through
                  other derivatives to make it so going forward we don't have
                  this misleading disconnect of the impact of gas prices on
                  one side of the transaction not being able to be offset by
                  the other side.  Our business strategy here was to have a
                  low risk gas sales program supported by reserves and
                  unfortunately the way the accounting treatment for these
                  contracts is that it is creating the illusion of risk that
                  doesn't exist.

S. Lawrence       The other charge, the $5 million approximately, we maintain
                  some cushion gas that's not hedged for uses as needed. There's
                  about 1.1, 1.2 BCF involved here that got marked up to $10 and
                  something cents at the end of last year and then got marked
                  down to less than $6 at the end of this quarter. Again, this
                  is strictly an accounting issue, but it exists.

D. Frank          Does your $1.00 to $1.10 guidance, what does that include
                  from an operating contribution from gas marketing?

L. Dow            We would expect the gas marketing business to be when you wash
                  out a lot of the accounting to be able to continue to have or
                  to have a very good contribution in 2001 of close to break
                  even to $0.10.

D. Frank          Thank you very much.

L. Dow            You're welcome.

Coordinator       Our next question comes from Zach Schriber of Silcap.

Z. Schriber       We were just wondering if you can sort of tell us about the
                  status of the gas storage draw downs.  I guess I understand
                  that you guys have some low cost gas in inventory, which
                  you've been $0.50 per MCF, which you've been sort of
                  sucking down and reselling that under the fixed price, the
                  $2.85 per MCF.  We're just wondering if that's what you're
                  doing and that's what accounts for the majority of this
                  positive $32 million for the quarter at the gas LDC.  I was
                  also wondering if you could talk to us about





                                                          MCN ENERGY GROUP, INC.
                                                    MODERATOR:  STEWART LAWRENCE
                                                       MAY 4, 2001/9:00 A.M. CDT
                                                                         PAGE 10


                  the physical integrity of the storage. There's been some sort
                  of scuttlebutt that potentially what you were doing could
                  jeopardize the physical integrity of the storage. We're just
                  wondering if you could address that.

L. Dow            I'd be happy to.  The first point, we are doing exactly
                  what we have indicated since early in 2001 we were going to
                  do and for that matter it was one of the hedges that we
                  discussed as we went through the end of 2000.  Much of the
                  increase in the first quarter is in fact the result of the
                  pulling out of storage gas at low cost.

                  Now from the physical standpoint we always cycle storage down
                  at the end of the winter period. So that it's not that,
                  physically, storage balances are any lower than they normally
                  are at March 31st, but the key is that our expectation is that
                  year-end 2001 we will not replace 25 BCF of the gas that we
                  have pulled from storage and that in fact we will have gas
                  contracts in the winter of 2002 where we're going to be buying
                  flowing gas from third party suppliers rather than pulling
                  from storage. There's nothing about the physical aspects up
                  here that's changing. We will sell storage services to third
                  parties in 2001, so storage balances owned by others will
                  likely be higher in MichCon storage fields at the end of the
                  year. But from integrity of the system and from reliability
                  there's nothing that we're doing that would change or have any
                  adverse impacts on that.

Z. Schriber       Can you tell us where storage levels are physically versus
                  financially now versus where they were at the end of 1999, the
                  end of 1998, and how much gas is actually in storage and how
                  does that compare to what you've historically had in storage?





                                                          MCN ENERGY GROUP, INC.

                                                       MAY 4, 2001/9:00 A.M. CDT
                                                                         PAGE 11


L. Dow            I don't have the numbers in front of me, but as of March
                  31st our storage balances at MichCon are in line with what
                  they've been in prior years.  They are a lot lower than
                  what they were in the December 31st period because clearly
                  we have higher storage balances traditionally going into
                  the winter period.  We typically plan on cycling storage
                  down to about a ten to 15 BCF of gas in storage at the end
                  of the withdrawal cycle and I believe that's where we're at
                  today as well.

Z. Schriber       Again, just to make sure I understand what you guys have
                  done is you've cycled physically the storage exactly the
                  same way that you have historically, but what you've done,
                  which is different, is you've re-categorized the inventory
                  such that the gas, which you are actually physically taking
                  out, you're charging yourself a lower cost of goods sold
                  for that physical gas based on the reshuffling of the
                  inventory.

L. Dow            Yes.  Reshuffling probably wouldn't be the word, but based
                  on our expectations as of year-end we will not replace that
                  gas.

Z. Schriber       Historically you do replace that gas at year-end, right?

L. Dow            Yes.  That's correct.

Z. Schriber       Why are you not going to replace that gas at year-end now?

L. Dow            Because we are using this storage to take us through the
                  gas choice program.  We made a commitment with MPSC and our
                  customers to have





                                                          MCN ENERGY GROUP, INC.

                                                       MAY 4, 2001/9:00 A.M. CDT
                                                                         PAGE 12


                  a $2.95 price for the three years. This allows us to honor
                  that commitment. We will instead in the winter of 2002 rather
                  than relying upon the storage withdrawals as we would have in
                  the past, we will be buying gas from flowing supplies from
                  third parties.

Z. Schriber       Then it becomes a pure pass through.

L. Dow            Yes.

Z. Schriber       Great.  The final question is you mentioned this cushion
                  gas as 1.2 BCF where we took a hit when gas prices came
                  down from $10 to $6 per MCF.  What was the gain, which we
                  experienced in the fourth quarter when gas prices shot up
                  to $10 per MCF and how was that gain treated if you could
                  just refresh us?

L. Dow            For that gas it would have been in the quarter would have
                  been written up from whatever the gas price was as of
                  September of 2001, which was probably in the $4 range, $4
                  to $5 range.  We probably marked up just one BCF or so from
                  $5 to $10.  There was a $5 million probably positive impact
                  in the fourth quarter of 2000.  This is just the reversal
                  of that positive impact.

Z. Schriber       Got it.  Again, on the merger can you just go over those
                  key dates, which you spoke about in your prepared remarks,
                  the key dates, which we should look out for again?

L. Dow            The key date would be the shareholder meeting of MCN
                  shareholders is May 15th. The proxy materials are out and the
                  shareholders are voting.

                  We expect the comment period for the SEC approval under the

Z. Schriber       Great.  Thanks so much, guys.

L. Dow            Thank you.

Coordinator       Our next question comes from Margaret Doris of First
                  Capital Alliance.

H. Chu            Actually this is Henry Chu at First Capital.  I'd like to
                  clarify how the dividends will be from an MCN shareholder
                  standpoint will be handled for the closing of the merger.
                  Will we receive the May dividend as well as a DTE dividend
                  for the payment in July or is there going to be some kind
                  of prorated dividend for closure?

S. Lawrence       The MCN dividend is certain. That one's been declared. The
                  shareholder meeting is not until May 15th, so MCN shareholders
                  are certain to hit the record date of May 11th without risk of
                  closing prior to that. That payment date is May 25th, which is
                  relatively meaningless. If we closed before May 25th it
                  doesn't make any difference, or after.

                  As far as qualifying for DTE's dividend, that one's not been
                  declared. Dave might want to speak to it a little bit. It's
                  normally this quarter's dividend, I believe the record date
                  would be June 20th. If that's going to be the case here then
                  if you're holding DTE shares as a result of converting or as a
                  result of buying on the open market or as a result of holding
                  for years and years, you would qualify for that dividend as
                  long as

                  you're a DTE stockholder at the dividend record date, which
                  again has not been declared yet.

H. Chu            As long as the transaction closes let's say hypothetically
                  by the end of May then we'll be eligible to receive the DTE
                  dividend.

S. Lawrence       That's correct.  This is the anticipated window period
                  where no coordination would be required, coordination of
                  dividends.

H. Chu            Great.  Thank you very much.

Coordinator       At this time there are no further questions. I'll return the
                  meeting to you, sir.

S. Lawrence       Thank you very much.  I appreciate everybody joining us
                  this morning and look forward to closing this deal and not
                  having another call.  Thank you very much.

L. Dow            Thank you.
