INDEPENDENT AUDITORS' REPORT
- ----------------------------

To the Trustees and Participants of
The GMAC Mortgage Corporation Savings Incentive Plan
Horsham, Pennsylvania

We have audited the accompanying statements of net assets available for benefits
of The GMAC  Mortgage  Corporation  Savings  Incentive  Plan (the  "Plan") as of
December 31, 1998 and 1997, and the related  statements of changes in net assets
available for benefits for the years then ended. These financial  statements are
the responsibility of the Plan's management. Our responsibility is to express an
opinion on these financial statements based on our audits.

We  conducted  our  audits  in  accordance  with  generally   accepted  auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements.  An audit also includes
assessing the  accounting  principles  used and  significant  estimates  made by
management,  as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our  opinion,  such  financial  statements  present  fairly,  in all material
respects,  the net assets  available for benefits of the Plan as of December 31,
1998 and 1997,  and the changes in net assets  available  for  benefits  for the
years then ended in conformity with generally accepted accounting principles.

Our audits  were  conducted  for the  purpose of forming an opinion on the basic
financial statements taken as a whole. The supplemental  schedules of (1) assets
held  for  investment  purposes  as of  December  31,  1998  and (2)  reportable
transactions  for the year ended December 31, 1998 are presented for the purpose
of  additional  analysis  and are not a  required  part of the  basic  financial
statements  but are  supplementary  information  required by the  Department  of
Labor's Rules and  Regulations  for Reporting and Disclosure  under the Employee
Retirement Income Security Act of 1974. The supplemental  information by fund in
the  statements of net assets  available for benefits  included in the financial
statements  and the  statements of changes in net assets  available for benefits
included in the notes to the  financial  statements is presented for the purpose
of  additional  analysis  rather  than to present the net assets  available  for
benefits  and changes in net assets  available  for  benefits of the  individual
funds.  The supplemental  schedules and supplemental  information by fund is the
responsibility  of  the  Plan's  management.  Such  supplemental  schedules  and
supplemental  information by fund have been subjected to the auditing procedures
applied in our audits of the basic financial statements and, in our opinion, are
fairly stated in all material  respects when considered in relation to the basic
financial statements taken as a whole.

THE GMAC MORTGAGE CORPORATION SAVINGS INCENTIVE PLAN

Notes:

      (1)  Trust to Trust  transfers  involve  mapping the funds from the former
           entity's  plan to the  Company's  current  plan.  Funds are  directly
           transferred  from  the  former  entity's  trustee  to  the  Company's
           trustee.
      (2)  Rollovers   afford  the  former   entity's  plan   participants   the
           opportunity to roll their funds into the Company's Plan. Participants
           are  eligible to rollover to the  Company's  Plan as of the  entity's
           acquisition date.

      In all types of  transfers,  employees of the former  entity are vested in
      accordance  with the Plan's  vesting  schedule and their original dates of
      hire, except where noted.

      (3)  Approximate  amount of assets to be  transferred  in a Trust to Trust
           transfer is noted  above.  No amount is  disclosed  for  Rollovers as
           participants are not required to roll funds over to the Plan.
      (4)  Acquisitions affecting the 1998 plan year are included in the current
           year  activity  noted  within the  statement of changes of net assets
           available for benefits.
      (5)  Prior to their acquisition by the Company, DiTech Funding Corporation
           employees did not  participate  in a 401(k) plan.  Upon  acquisition,
           employees of the former DiTech Funding  Corporation were eligible for
           participation  in the  Company's  Plan.  Employees  will be vested in
           accordance with the Plan's vesting  schedule and their original dates
           of hire.
      (6)  Former employees of Carlson Real Estate Company,  Norwood Real Estate
           Company and Landry,  Lyons & Whyte  Company are vested in  accordance
           with their former plan's vesting schedule and their original dates of
           hire.

      The Plan is sponsored  and  administered  by the Company.  At December 31,
      1998 and 1997, all assets were held in trust at Fidelity  Management Trust
      Company, Inc.

      A general  description of the Plan provisions is incorporated in the notes
      which  follow.  A Summary  Plan  Description,  providing a more  extensive
      description  of Plan  provisions,  has been  published and is available to
      participants in the Plan.

2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

      The financial statements of the plan are prepared on the accrual method of
      accounting.   The  significant   accounting   policies   followed  in  the
      preparation of the accompanying financial statements are as follows:

      .  Investment  transactions  are recorded on the trade date and investment
         balances  are  stated at fair  value.  Assets  are  invested  in common
         stocks, mutual funds and pooled separate accounts are carried at quoted
         market price.  Participant loans are valued at cost, which approximates
         fair value.

      .  Net  appreciation in fair value of investments is computed based on the
         fair value of investments at the beginning of the Plan year.

THE GMAC MORTGAGE CORPORATION SAVINGS INCENTIVE PLAN

      .  Dividends  and interest are included in income when earned based on the
         term of the  investments  and the periods during which the  investments
         are owned by the Plan.

      .  Balances in the loan fund are carried at the principal balance
         outstanding.

      .  Distributions are recorded when paid.

      .  The  preparation  of  the  financial   statements  in  conformity  with
         generally accepted  accounting  principles  requires management to make
         estimates and  assumptions  that affect the reported  amounts of assets
         and liabilities and disclosure of contingent  assets and liabilities at
         the  date of the  financial  statements  and the  reported  amounts  of
         revenues and expenses during the reporting  period.  Actual results may
         differ from those estimates.

3.    CONTRIBUTIONS TO THE PLAN

      Annual  additions  to  an  Employee's   account  are  subject  to  certain
      limitations imposed by the Plan.  Employees may elect to contribute to the
      Plan on a pre-tax basis, in even multiples of 1% of base compensation,  up
      to 12% of  compensation  (subject to a limit of $10,000 and $9,500 for the
      years  ended  December  31,  1999 and 1997,  respectively).  The  Employee
      contribution   limitation  is  evaluated   annually  to  determine  if  an
      adjustment  for cost of living  increases  to the extent  permitted by the
      Internal Revenue Code of 1986, as amended (the "Code").  Effective July 1,
      1997,  the  contribution  level was increased  from 9% to 12%. The Company
      will match an Employee's contribution in cash up to 6% of compensation, to
      an annual limit of $3,000.  Employer contributions are made to the General
      Motors  Unitized Stock Fund.  Based on the Employee's  election,  employee
      contributions  can be  directed  to any of  several  investment  funds  or
      options  (see  Note 7).  Participants  may  elect to  change  contribution
      elections  daily and are  permitted to change  allocations  among funds or
      transfer balances between funds, in 1% increments daily.

4.    VESTING

      Two pre-tax basis accounts are maintained for each participating Employee.
      The Salary Reduction Account consists of a participant's contributions and
      is  fully  vested.   The  Matching   Account  consists  of  the  Company's
      contributions.  A  participant's  Matching  Account  vested balance is 20%
      after one year of credited  service and increases 20% per year  thereafter
      until fully vested.

      While the Company has not  expressed  any intent to terminate the Plan, it
      may do so at any time.  In the  event of  termination  of the  Plan,  each
      participant's  Matching  Account becomes fully vested to the extent of the
      amount in the participant's Matching Account.

THE GMAC MORTGAGE CORPORATION SAVINGS INCENTIVE PLAN

5.    DISTRIBUTIONS

      Participants   may  withdraw   their  vested  assets  at  any  time  after
      termination of employment.  Prior to termination of employment, the assets
      may  only be  withdrawn  because  of  disability  or  financial  hardship.
      Participants  may elect to receive  their  withdrawal in either a lump-sum
      payment, by purchase of various annuities or over various periods of time.
      Participants  may also  elect a  distribution  of  shares  of stock to the
      extent shares have been credited to their account.  Participants also have
      the option of borrowing  against their vested  balances in an amount up to
      50% of the  participant's  accrued  vested  benefit as  determined  on the
      valuation date, or $50,000, whichever is less (see Note 8).

6.    FORFEITURES

      Participant   forfeitures  are  utilized  to  reduce  subsequent   Company
      contributions.   Upon   termination,   the   nonvested   portion   of  the
      participant's Matching Account is forfeited.

7.    INVESTMENT FUNDS OR OPTIONS

      Participants  can direct the Plan Trustee to make  investments of Employee
      contributions in the Investment Options described below:

      Fidelity Growth & Income Fund - The fund seeks  long-term  capital growth,
      current income and growth of income consistent with reasonable  investment
      risk.  It invests in common  stocks,  securities  convertible  into common
      stocks, preferred stocks and fixed income securities.

      Fidelity Magellan Fund - The fund seeks long-term capital  appreciation by
      investing in stocks of both  well-known  and  lesser-known  companies with
      potentially  above-average  growth potential and a correspondingly  higher
      level of risk.  Securities may be of foreign,  domestic and  multinational
      companies.

      Fidelity  Managed  Income  Fund - The fund seeks to  preserve  capital and
      provide  a   competitive   level  of  income  over  time.   It   purchases
      high-quality,   short-  and  long-term   investment  contracts  issued  by
      insurance companies, banks and other approved financial institutions.

      Fidelity  Contrafund - The fund seeks  long-term  capital  appreciation by
      investing  mainly in the  securities  of  companies  believed to be out of
      favor or  undervalued.  The fund invests in common  stocks and  securities
      convertible  into common stock,  but it may purchase other securities that
      may produce capital appreciation.

      Fidelity  Asset  Manager  Fund - The fund seeks a high total  return  with
      reduced risk over the long term by  allocating  its assets among  domestic
      and foreign equities, bonds and short-term instruments.

      Fidelity Retirement  Government Money Market Fund - The fund seeks as high
      a level of  current  income  as is  consistent  with the  preservation  of
      principal and liquidity. It invests in obligations issued or guaranteed as
      to  principal  and  interest  by the  U.S.  Government,  its  agencies  or
      instrumentalities,   and  in   repurchase   agreements   secured   by  the
      obligations.

THE GMAC MORTGAGE CORPORATION SAVINGS INCENTIVE PLAN

      Fidelity Overseas Fund - The fund seeks long-term capital growth primarily
      through investments in foreign securities.  Investments may include common
      stock, securities convertible to common stock and debt instruments. Due to
      currency  fluctuations  and  the  political  and  economic   uncertainties
      associated  with  foreign  investments,  the risks and  potential  rewards
      relating  to  this  fund  are  greater  than  funds  which  purchase  U.S.
      investments.

      Fidelity  OTC  Portfolio  Fund - The fund seeks  capital  appreciation  by
      investing  mainly in  equity  securities  traded  on the  over-the-counter
      market.

      Fidelity  Puritan Fund - The fund seeks high income with  preservation  of
      capital and the potential  for growth of capital.  It invests in a broadly
      diversified portfolio of high-yielding equity and debt securities.

      Fidelity  Small Cap Stock Fund - The fund seeks  capital  appreciation  by
      investing  mainly in equity  securities  of  companies  with small  market
      capitalization  believed  to be  undervalued  compared  to others in their
      industry.  The fund may also invest in all types of equity  securities and
      may invest a portion of its assets in the stock of  companies  with larger
      capitalization.

      Fidelity  Ginnie Mae Fund - The fund seeks a high level of current  income
      by investing primarily in Government National Mortgage Association (Ginnie
      Mae) securities and other securities that are guaranteed by the full faith
      and credit of the U.S. Government and private issuers. Assets not invested
      in Ginnie  Maes may be  invested  in any type of U.S.  or foreign  debt or
      other income producing investments.

      Fidelity Freedom Funds - These funds provide investment diversity based on
      the  projected  years to  retirement.  A  participant  can choose the fund
      tailored to their retirement specification. These funds eliminate the need
      for the investor to determine the asset allocation.  Five Fidelity Freedom
      Funds are included in the plan.  Fidelity  Freedom  Income Fund,  Fidelity
      Freedom 2000,  Fidelity Freedom 2010,  Fidelity Freedom 2020, and Fidelity
      Freedom 2030.

      General Motors Unitized Stock Fund - The objective is to provide a General
      Motors Stock  investment  option that can be traded and accessed  with the
      same  frequency  and  timeliness as a Fidelity  mutual fund.  This fund is
      primarily  comprised  of GM Common  Stock and a small  percentage  of cash
      and/or other liquid  investments  (usually 1-3%).  The availability of the
      cash makes it possible to trade shares of GM Common Stock without  waiting
      the  mandatory  five-day   settlement   period.   During  1998  and  1997,
      contributions to each  participant's  Matching Account are invested in the
      GM Unitized Stock Fund.

     First Union Financial Corp.  Common Stock  (formerly  CoreStates  Financial
     Corp.  Common  Stock)  - The  option  is the  residual  of the  former
     Colonial Companies Savings  Incentive Plan (which became the Plan in 1986).
     Activity is limited to the reinvestment of earnings and participant
     distributions.

THE GMAC MORTGAGE CORPORATION SAVINGS INCENTIVE PLAN

      Raytheon Stock Fund - Effective December 17, 1997, GM spun-off the defense
      electronics  business  of  Hughes  Electronics,  a GM  subsidiary  (Hughes
      Defense),  to holders of $1-2/3  par and Class H common  stock,  which was
      immediately  followed  by the  merger  of  Hughes  Defense  with  Raytheon
      Company. In connection with the above transaction, Raytheon Class A common
      stock was distributed to holders of GM $1-2/3 par value and Class H common
      stocks.  Plan  participants  holding  Class H Common Stock Fund units were
      allocated  approximately .81 units of Raytheon Class A units for each unit
      of GM Class H held. Plan  participants  holding GM $1-2/3 par value Common
      Stock Fund units were allocated  approximately .08 units of Raytheon Class
      A units  for  each  unit  of GM  $1-2/3  held.  The  determination  of the
      allocation  ratio for units was based on the  number of units  held in the
      Plan.  Such  exchange  was  recorded  as  a  stock  dividend  and  totaled
      approximately  $314  million of which $172  million and $142  million were
      distributed  to $1-2/3 par value  common  stockholders  and Class H common
      stockholders, respectively.

      This  exchange  required the addition of Raytheon  Common Stock Fund which
      will remain as an investment option through December 31, 2002; however, no
      further  contributions or exchanges from any other investment options into
      the  Raytheon  Common  Stock  Fund will be  permitted  during  that  time.
      Dividends,  if any,  paid on  Raytheon  Class A Common  Stock held will be
      invested  in an income  fund  investment  option  prior to  allocation  to
      participant's accounts.

      Assets held in this fund are expressed in terms of units and not shares of
      stock. Each unit represents a proportionate interest in all assets of this
      fund. The value of each participant's  account is determined each business
      day by the number of units to the participant's credit,  multiplied by the
      current unit value.  The return on a participant's  investment is based on
      the value of units,  which,  in turn, is determined by the market price of
      the  Raytheon  Class A Common  Stock,  the  amount of any  dividends  paid
      thereon,  and any interest  earned on short-term  investments  held by the
      fund.

THE GMAC MORTGAGE CORPORATION SAVINGS INCENTIVE PLAN

8.    LOANS RECEIVABLE FROM PARTICIPANTS

      Active  participants in the Plan are generally eligible to borrow from the
      Plan  up to the  lesser  of  $50,000  or 50% of the  participant's  vested
      account balance.  Interest on participant  loans is determined by the Plan
      Administrator  based on rates  offered by  commercial  lenders for similar
      type loans. Loan repayments are in level monthly  installments over a term
      not to exceed five years.  Loans are funded through the liquidation of the
      participant's related investments.  Repayments of principal are reinvested
      based upon the participant's  current investment options.  During the year
      ended  December  31,  1998,  there  were   approximately   $2,746,000  and
      $1,949,000 of new borrowings and principal  repayments,  respectively.  At
      December  31,  1998,  there  were 818 loans  outstanding  with an  average
      balance and interest rate of $5,392 and 9.76%,  respectively.  At December
      31, 1997,  there were 667 loans  outstanding  with an average  balance and
      interest rate of $5,489 and 9.51%, respectively.

      Two of the  employees  of the Company who serves on the Pension  Committee
      also  have  outstanding   loans   receivable.   Loan  activity  for  these
      individuals for the years ended December 31, 1998 and 1997 is as follows:

                                             1998          1997

      The Plan  obtained  its latest  determination  letter on July 13,  1995 in
      which the Internal  Revenue  Service stated that the Plan,  subject to the
      adoption  of several  technical  amendments,  was in  compliance  with the
      applicable requirements of the Internal Revenue Code. The Plan adopted the
      technical  amendments  on August 9, 1995 to comply  with the  requirements
      noted in the letter.  Therefore,  no  provision  for income taxes has been
      included in the Plan's financial statements.

      Temporary  employees  do not  normally  qualify  for  benefits  due to the
      expected tenure of their employment.  However,  from 1993 to 1996, certain
      temporary  employees qualified for Plan benefits as a result of working in
      excess of 1,000 hours for the eligibility  computation  period.  Due to an
      administrative  error,  these  employees were not given the opportunity to
      participate  in the Plan.  As a result,  the  Company has filed for relief
      with  the IRS  under  the  Standardized  Voluntary  Compliance  Resolution
      Procedure  ("SVP") and will make  contributions  required to obtain relief
      under  SVP.  The  Company  has  developed  an  estimate  of the  potential
      additional contributions which are not material to the Plan.
