               This Amendment No. 3 ("Amendment No. 3") to the Rule 13e-3
Transaction Statement on Schedule 13E-3 filed on February 25, 1999 (the
"Original Schedule 13E-3" and together with Amendment No. 1 filed on April
2, 1999, Amendment No. 2 filed on April 20, 1999 and, as amended hereby, this 
"Schedule 13E-3") is being filed jointly by TIC Acquisition LLC, a Delaware 
limited liability company (the "Acquiror"), The Irvine Company, a Delaware 
corporation ("TIC"), and Mr. Donald Bren in connection with the proposed 
merger (the "Merger") of Irvine Apartment Communities, Inc., a Maryland 
corporation (the "Company"), with and into the Acquiror pursuant to an Agreement
and Plan of Merger, dated as of February 1, 1999 (the "Merger Agreement"), by
and between the Company and the Acquiror. TIC is the managing member of the
Acquiror and the sole shareholder of the only other member of the Acquiror. By
filing this Schedule 13E-3, none of the joint signatories concedes that Rule
13e-3 under the Securities Exchange Act of 1934, as amended, is applicable to
the Merger or the other transactions contemplated by the Merger Agreement.
    

               In the Merger, the Company will merge with and into the Acquiror,
with the Acquiror as the surviving company. Upon the effectiveness of the Merger
(the "Effective Time"), each share of common stock, par value $.01 per share, of
the Company (the "Shares"), issued and outstanding immediately prior to the
Effective Time will be converted into and represent the right to receive $34.00
in cash, without interest, subject to applicable back-up withholding taxes.

   
               This Amendment No. 3 is being filed with the Securities and
Exchange Commission concurrently with a revised preliminary proxy statement
filed by the Company pursuant to Regulation 14A under the Securities Exchange
Act of 1934, as amended (the "Proxy Statement"). A copy of the Proxy Statement
is attached hereto as Exhibit 99.1. The following cross reference sheet is being

                                EXPLANATORY NOTE
                           (Not Part of This Exhibit)

Pursuant to the requirements of Rule 13e-3 of the Exchange Act, the following
preliminary analysis is being filed as an exhibit to the Schedule 13E-3. The
following preliminary analysis was prepared by Morgan Stanley and discussed with
the Special Committee on December 22, 1998. The information contained in the
preliminary analysis was prepared as a negotiating tool and to provide the
Special Committee with some background information with respect to possible
alternatives in connection with the offer made by TIC Acquisition LLC. It is
important to note that neither the due diligence nor the analysis performed by
Morgan Stanley reflected in the above referenced draft was complete at the time
the preliminary draft was prepared and it was not intended to be relied upon by
the Special Committee or any third parties, including the Shareholders. The
Special Committee was aware of the status of and the preliminary nature of the
draft and the fact that it was not to be relied upon. The preliminary analysis
was prepared as of December 22, 1998 and reflects information made available to
Morgan Stanley prior to such date. Therefore, Morgan Stanley's preliminary
analysis performed as of December 22, 1998 does not and did not reflect the
final views of Morgan Stanley with respect to Morgan Stanley's valuation of the
Company or an opinion as to the fairness of the proposed transaction as of the
date it was provided to the Special Committee.

BACKGROUND / CHRONOLOGY

     -    On December 1, 1998, following the close of trading, Beta published a
          proposal (the "Proposal") to acquire the shares of Alpha (or the
          "Company") it does not already own in a going-private transaction

          -    Price: $32.50/share

          -    Declared to have no financing contingency

          -    Contemplates a cash merger with no tender to precede (draft
               Merger Agreement has been received)

     -    A special committee was formed by Alpha's Board of Directors to work
          with legal and financial advisors in considering the Proposal and
          formulating a response

     -    On December 8, 1998, Morgan Stanley was notified that it had been
          selected by the special committee as the Company's financial advisor

     -    On December 10, 1998 Morgan Stanley requested and began receiving and
          reviewing information for Alpha

     -    On December 15, 1988, Morgan Stanley met with management and local
          consultants of Alpha to discuss a number of topics:

          -    Review of business plan

          -    Review of projections / company model

          -    Discussion of market conditions and market studies

                                Executive Summary

FINANCIAL ANALYSIS


     -    In evaluating the Proposal, we have attempted to estimate a valuation
          range for the Company by the application of several different
          valuation methodologies

          -    Net asset value: Looks at the current value of the Company's
               assets on an asset sale basis, netting out debt and preferred to
               estimate common equity value. This is analogous to liquidation
               value, although debt and preferred penalties to retire are not
               included nor is the time value of any disposition program

          -    Discounted cash flow: Relies on projections, based on several
               scenarios, of the Company's performance to estimate a going
               concern value, either under the current capital structure or
               under a more highly leveraged structure consistent with the
               Proposal

          -    Comparable company analysis: Estimates the value of the Company
               based on trading levels of selected peers, without implying that
               it has traded or would trade similarly. It is important to note
               that no good comparable company exists

          -    Ability-to-pay: Estimates the value of the Company if it were
               acquired by another public apartment company based on a variety
               of assumptions as to the acquirer's acceptable level of earnings
               accretion or dilution

          -    Comparable multifamily transactions: Looks at other transactions
               that have occurred in the sector. As these (a) were typically
               mergers of equals and (b) involved stock as consideration as
               opposed to cash, they are not considered sufficiently comparable
               so as to allow meaningful value conclusions to be drawn

          -    Comparable squeeze-out transactions: Reviews premiums paid in
               prior squeeze-out transactions. Although a resulting range is
               shown, the applicability is limited because of variations, among
               other factors, in the rights of each side and the pre-offer
               public trading valuation relative to a theoretical intrinsic
               value

          -    Wall Street's view: Synopsis of statements as to the value of the
               Company published by research analysts before and after
               publication of the Proposal

ALTERNATIVE TRANSACTIONS

     -    To assess the Proposal, a number of other potential transactions were
          reviewed and assessed

               -    These transactions included doing nothing (status quo, an
                    alternative which the Company is in a strong position to
                    elect to pursue), pursuing a strategic partner other than
                    Beta, and extinguishing the Land Rights Agreement (in
                    conjunction with some or all of the following elements: sale
                    of the Company, sale of assets to Beta, recapitalization)

               -    They were assessed on the basis of

                    -    Shareholder value
                    -    Execution risk
                    -    Future access to capital and business plan risk
                    -    Tax impact to shareholders
                    -    Resolution of issues relative to Beta

                               Key NAV Assumptions


STABILIZED PROPERTIES

The 55 stabilized properties including two recent acquisitions, were placed into
three tiers based upon:

               - year built             - average rent
               - location               - quality

Each tier was ascribed a cap rate range:

               Tier I      Newer properties in prime locations with highest 
                           rents. Cap rate range: 7.25% - 7.75%
               Tier II     Late 1980s product including the student housing
                           properties. Cap rate range: 7.5% - 8.0%
               Tier III    Older product, lower average rent. Cap rate 
                           range: 7.75% - 8.25%

Cap rates were applied to 1999E NOI

These ranges were evaluated and deemed appropriate in light of cash flow yields
(NOI less capital reserves) which would be about 96% as high
Net operating income was calculated based on:

               - 4th quarter forecasted NOI was annualized
               - Operating margin is assumed to be 70% and annual revenues are
                 increased 5% to 10%
               - Expenses are escalated at 3%

PROPERTIES UNDER DEVELOPMENT

Properties under development were valued as follows:

               DCFs were performed for each property from 1/1/99 until
                  stabilization
               Cap rates were applied ranging from 7.25% to 8.25% to compute
                  terminal value at stabilization
               Discount rates of 12% to 16% were utilized 
               The values computed were adjusted by development costs to be 
                  incurred from 9/30/98 to 1/1/99

LAND RIGHTS AGREEMENT

The Land Rights Agreement was calculated utilizing two methodologies:

     I.   Below-market land acquisition prices

          Assuming the land is being transferred to Alpha at prices below what a
             third party would pay, the value differential was calculated given
             Alpha pays 95% of appraised value, with a total discount of 5% to
             15% compared to a third party 

          The agreement was valued based upon the following variables:

<TABLE>
<S>                                         <C>
Discount to market: 5% to 15%               Average cost/unit: $50,000 to $75,000
Units Developed: 1,000 to 1,500 per year    Discount Rates: 10% to 13%
</TABLE>

     II.  Value of Non-Compete

          The value differential between Alpha having the Agreement and the
             choice to develop, versus a third party developing on-ranch
          The agreement was valued based upon the comparison of two DCF 
             analyses:

          1.   Third party developer develops on-ranch, rents increase 7% in
               1999, 4% in 2000, and 3% thereafter

          2.   Alpha stops developing on-ranch, rents increase over time, at
               rates of 1% to 2% above rates for Analysis I

                              Process / Next Steps

- -    Many elements / audiences need to be considered in determining the next
     actions to be taken by the special committee

     -    Beta

     -    Management 

     -    Public shareholders / other potentially interested parties

- - The most important response is to Beta

     -    Form of response

     -    Consider providing an indication of value / range of values

     -    Timing of response

     -    Also need to consider the appropriate messenger

- -    Dealing with management is also critical

     -    Ensure appropriate participation by key people in this process, which
          will help maximize value for shareholders

          -    Stay bonuses

          -    Change-of-control termination compensation

     -    Preserve ability of Company to function if Proposal or other
          transaction is not completed 

- -    Gaining shareholder support for the selected course of action is imported

     -    Share price reaction to announcement will indicate support or
          opposition -- important to Board for reaction to be positive

     -    Shareholder vote required: will be influenced by research analysts'
          reactions

- -    Other potential steps to consider

     -    Public announcement of engagement of advisor

     -    PR program to create negotiating leverage, specifically if
          negotiations with Beta are not progressing

IRVINE APARTMENT COMMUNITIES
Irvine Company Buyout Proposal: Rich Price - No, Reasonable Price - Maybe
(N/IAC)

         December 10, 1998 * Recent Price $31.81 * DJIA 9009 * RMS 305
- --------------------------------------------------------------------------------
I. SUMMARY

The Irvine Company (TIC), through a wholly-owned unit, recently proposed to
purchase the 16.6 million shares (83% of the common shares outstanding, or 37%
of the combined common shares and OP units outstanding) of Irvine Apartment
Communities (IAC) that it doesn't already own. The proposed price is $540
million, or $32.50/sh, a 19% premium to the prior day's closing price of $27.38.
TIC is clearly paying a large premium to the value that the public market
ascribed to IAC, but the buyout price does not fully reflect the intrinsic value
of the company and operating partnership as a whole.

TIC's offer is not subject to a financing contingency, and calls for IAC's
existing debt and preferred stock to remain outstanding. TIC announced that it
does not expect the debt or preferred stock to be affected by the transaction.
The offer will be financed from TIC's balance sheet, with the proceeds infused
into IAC as equity, thereby leaving IAC's debt and preferred stock unaffected
from a capital structure standpoint. What is less certain is how the rating
agencies will react as a result of "intangible" changes at IAC. The change in
the financial management team, the possible perception that the new IAC could
lack public market discipline, and the reduction in financing options available
to a private company may be discomforting to the agencies and could result in
negative rating implications. After the announcement of the offer, IAC was put
on credit watch for possible downgrade.

If IAC and the assets of the operating partnership were auctioned off in their
entirety, the company would likely fetch a higher price. However, TIC's majority
control, and the special voting rights that were afforded TIC at the formation
of the company, effectively preclude such an auction from taking place.
Therefore, evaluating the appropriateness of the pricing of the proposal raises
some interesting valuation issues, not the least of which is the disparity in
pricing that the public market ascribed to IAC versus what a private buyer might
pay.

IAC's Board of Directors may determine that the pricing is inadequate, but be
hard pressed to refute the proposal due to the robust premium being offered. At
the end of the day, we believe most shareholders would support the current
offer, but there could be some upside to the price if IAC's Board squawks loud
enough. Of course, squawking too much runs the risk of having TIC revoke its
offer entirely, although that risk is probably remote. In any event, it is hard
to envision a scenario where shareholders aren't at least paid a minimum of
$32.50/sh for their holdings.

The closing date of the transaction is uncertain, but is likely to fall sometime
near the end of the first quarter or early in the second quarter of 1999.
Assuming the company declares and pays a fourth quarter dividend, and the
transaction is completed at the stated price within fourth months, investors
would generate an annualized return of roughly 12% at the current share price.

The proposed buyout is interesting because it sends two messages to the REIT
industry. First, a savvy real estate industry veteran, Donald Bren (TIC is
privately held and 100% owned by Mr. Bren), has suggested that the REIT
structure doesn't work for his company. Mr. Bren's conclusion may be alarming to
most REIT proponents, but it shouldn't be because his situation is unique. We do
not foresee a wholesale movement to de-REIT or go private by other REIT
management teams despite such speculation by others. Second, and perhaps more
importantly, Mr. Bren, one of the most successful real estate entrepreneurs in
recent history, determined that the public market valuation of his company was
at least 19% too low. While some may choose to ignore it, the signal being sent
by Mr. Bren should be bullish for REITs in general, and apartment REITs with
exposure to California in particular.

STRUCTURE OF IAC AND RELATED ENTITIES

                                  [FLOW CHART]

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

I. STRUCTURE

Exhibit 1 contains a chart depicting the structure of IAC and its operating
partnership. As can be seen, TIC has a sizable (63%) economic interest in the
operating partnership, directly through its limited partner interest and
indirectly through its ownership of IAC shares. The bottom line is that public
shareholders own a minority interest in the operating partnership, although they
own a majority interest in IAC, the sole general partner of the partnership.
Despite controlling a majority interest in the general partner, public
shareholders do not have complete control over the partnership.

The Operating Partnership Agreement, the Certificate of Incorporation, and IAC's
Bylaws effectively prohibit any sale, merger, or business combination of IAC or
the operating partnership without the approval of TIC. Thus, IAC is not in a
position to "auction" off the entire company, and is at a disadvantage when it
comes to ensuring that the best possible price is paid for its interests. This
is not to say that TIC's current offer is coercive or even unreasonable in any
way, but rather that other potential bidders are effectively locked out of
competing for the company. As a result, TIC is not under as much pressure to
offer the "best" price possible when proposing to buy the company. All other
things being equal, TIC has an incentive to pay only the minimum price that gets
the deal done. We have heard some argue that TIC may have aspirations of someday
returning to the public market, either with IAC's portfolio or the balance of
its commercial real estate holdings, and therefore is motivated to pay an
inflated price to leave public shareholders with a good taste in their mouths.
While the logic may be sound, $32.50/sh does not represent premium pricing for a
portfolio and company of IAC's quality.

III. NAV AND PRICING

In Exhibit 2, we present a range of NAV calculations for IAC as of 9/30/98 
using various capitalization rates. Heretofore, we have used an economic cap 
rate of 7.9% to value IAC's portfolio knowing that other apartment assets in 
IAC's markets have traded hands at much lower cap rates (i.e. higher values). 
We knowingly used an above-market cap rate for two primary reasons. First, the 
7.9% rate, although not reflective of "market", was a full 30 basis points 
lower than that used to value any other apartment REIT portfolio, and REIT 
investors have displayed a discomfort with valuing fringe companies too 
dissimilarly from the average. Second, despite the use of an above-market cap 
rate, we have had a very strong buy on the company for some time, and recently 
touted the company as the

cheapest apartment REIT, and possibly even the cheapest REIT overall. Herein, we
present a range of economic cap rates from 7.0% to 7.5%. While we present three
scenarios, our best guess is that the NAV of the company really falls somewhere
around the mid-range, namely $33.50/sh (rounded). In our calculations we attempt
to give credit for the current development projects, but ascribe no specific
value to the Land Rights Agreement between TIC and IAC which gives IAC the
exclusive right to develop apartments on TIC's extensive land holdings through
the year 2020.

The value of the agreement is difficult to quantify because TIC is not obligated
to sell land to IAC, but should it so desire, or be required, to have apartments
developed, it must sell such land to IAC at a price that is no more than 95% of
appraised value. Any appraisal based system is subject to abuse and/or vagaries,
but here the pricing mechanism seemed to work to IAC's advantage because the
third party "comps" that would presumably be used would most likely be inferior
properties. Also, if IAC wanted to play hardball, it could preclude the
development of any new apartments on TIC owned land, and effectively "force"
favorable pricing in the event that apartments had to be developed (zoning
authorities often require a minimum amount of affordable housing). At the end of
the day, it is nearly impossible to accurately estimate the value of the
agreement, but at the very least it is worth something to TIC to buy itself out
of the obligation.

At $32.50/sh, TIC's offer is at the lower-end of our estimate of the range of
IAC's true NAV, and equates to an economic cap rate of 7.4% (a nominal cap rate
of 7.7%), representing a per unit value of approximately $130,000. The per unit
value may sound high, but other inferior apartment assets located in Orange
County have closed during the last few months at valuations of $128,000-$148,000
per unit. TIC's offer ascribes no value to terminating the Land Rights 
Agreement, nor any "franchise value" for IAC, which has been active in creating
value through development off the Irvine Ranch in San Diego and Northern
California. Thus, using an intrinsic value approach, the offer price appears to
represent a discounted value based on recent private transactions, and should
provide TIC with meaningful upside.

IV. CONCLUSION

This transaction is unique in several ways. TIC's majority ownership position of
the operating partnership effectively gives it control, and diminishes the value
of IAC's minority interest position. The pricing of REITs of late provides an
opportunity for TIC to offer a premium to the public market price, but a dis-

count to the private market value. The independent committee of IAC's Board
faces an interesting valuation issue, but should be motivated to maximize the
value of the offer. James Mead, IAC's CFO, recently announced his resignation
from the company, and may serve as a good advocate for shareholders; although he
no longer owns shares himself. Mr. Mead is arguably well suited to assess the
value of IAC, and doesn't appear to have a bias in determining the
appropriateness of the current offer.

How IAC's Board ultimately decides to proceed is anybody's guess. TIC's offer is
not fully-priced based on the public's pro rata share of the value of the
company as a whole, but it is not a low-ball offer either. At a 19% premium to
the public market's valuation of the company, TIC's offer is much more richly
priced than other acquisition or merger transactions that have occurred in
REITdom, suggesting that the price is more than reasonable on that measure. The
Board could determine that the offer is acceptable, and have a fairly good
defense for that conclusion. On the other hand, the Board could determine that
the offer must reflect IAC's pro rata share of the full value of the company or
something more close to it. If the Board takes this second stance, there is a
risk that TIC withdraws its offer and the shares trade back to their previous
range, although we believe that risk is remote. More likely TIC would either up
its bid, or perhaps call a shareholder vote (which Mr. Bren can do as Chairman
of the Board) and allow investors to directly evaluate the merits of the
proposal.

The reality of the situation is that Mr. Bren will be the one to decide whether
a higher price will be paid. IAC's Board can bluster and posture for a fight,
but we think Mr. Bren will ultimately be successful even if the offer is not
increased. His offer is, by any definition, reasonable. However, he has
contended that the offer is actually rich, as a result of his desire to exit the
public market with a feeling of good will from the investment community. We,
however, strongly disagree with his contention that this offer is rich. If he
truly wants to leave investors with a favorable impression, the offer needs to
be increased. The odds of this happening are highly influenced by his own
perception of whether TIC, IAC or some combination thereof may later wish to
access public equity markets again. On this point, we think there is a
reasonable chance of an Irvine-related entity coming public at some point in the
future. Because of this, there is also a reasonable chance that he will choose
to up his offer. We would not suggest that this is a high probability, but we
believe it is a legitimate possibility.

At the recent price, we recommend investors continue to BUY shares of IAC. At a
minimum, they should provide close to a 12% annualized return and a sweetened
bid by TIC could enhance that return.

                 IRVINE PROPOSES TO GO PRIVATE. IS THIS THE FIRST OF MANY? IS
                 THE DEAL FAIR?

                                                                December 6, 1998

                 The answer to the first question is maybe some, but not many.
                 There is a lot that makes Irvine very different from most other
                 REITs, particularly in aspects which affect the probability of
                 going private. Seeing what makes Irvine different goes a long
                 way to sorting out the probabilities of others following its
                 example. It also provides some insight into the second question
                 as to whether this deal is really good and fair for
                 shareholders. While it is still early, an affirmative answer on
                 the fairness issue seems a stretch.


The Facts

                 Late Tuesday, a special purpose affiliate of The Irvine Company
                 proposed to purchase all of the outstanding common shares of
                 Irvine Apartment Communities, Inc (IAC: NYSE; hereinafter IAC,
                 or the Company) at a price of $32.50 per share, $5.69 or 21.2%
                 over their closing price the prior day, and $15.00, or 85.7%
                 over their $17.50 price at their December 1993 IPO. The Irvine
                 Company and its affiliates, all largely controlled by Donald
                 Bren, owned IAC outright prior to the IPO, and afterwards
                 continued to hold an approximate 63% interest in IAC, largely
                 in the form of Operating Partnership units. Irvine Company
                 management estimated the compound annual return to shareholders
                 since the IPO to a takeover at this price would be 19.8%, a
                 number which would argue that the take-over was a good deal.
                 But a good deal is not necessarily a fair deal; there seem
                 certain other alternatives that would address the needs stated
                 by Mr. Bren in a manner shareholders might feel better serves
                 their differing interest.

The Differences 

                 An unusually large number of facts and circumstances make IAC
                 quite different from most other REITs and, in almost all these
                 areas of difference, make a similar privatization less likely.
                 These include a variety of factors reflecting both

                 the feasibility of going-private and incentives unique to The
                 Irvine Company for so doing.

                 FEASIBILITY CONSIDERATIONS: LEVERAGING THE PURCHASE. It seems
                 reasonable to assume that the aggregate purchase price of $540
                 million will be funded by a borrowing against the IAC assets,
                 or at least that would be preferable if it were feasible. The
                 feasibility of arranging this borrowing depends on both not
                 exceeding aggregate loan-to-value ratios at which most lenders
                 would balk and having collateral available to pledge to these
                 lenders. Both these considerations are made relatively more
                 easy by the shares to be purchased being less than a majority
                 of all outstanding shares and OP equivalents, more specifically
                 being 37% of shares and equivalents. Secondly, if the Company
                 is valued at a 9.0% cap rate, then existing liabilities
                 represent 41.3% of value and the $540 million to be borrowed
                 would represent 28.3%; the resulting post-privatization entity
                 would be leveraged at 69.6%, generally a quite feasible
                 level.(1) In an important sense, leveraging for this purchase
                 may be even easier than these ratios indicate because a great
                 deal of the Company's debt is very low cost debt. For the most
                 recent quarter, the Company had a very healthy interest
                 coverage ratio of 5.44 times; if it were to borrow the
                 $540 million at 7.0% - if anything, a slightly lower rate seems
                 feasible -- its coverage ratio would be 2.44 times, still very
                 acceptable to even the most cautious of lenders.

                 The last possible constraint is the availability of
                 unencumbered collateral to pledge to a lender. Based on the
                 Company's 1997 10K, secured indebtedness encumbers only 63% of
                 assets completed at that time, or 55.3% of assets including
                 (and treating as unencumbered) properties then under
                 development.(2) If all properties have uniform per-unit
                 valuations, then borrowing $540 million against unencumbered
                 assets would produce only an 87% loan-to-value on these pledged
                 assets, assuming these assets are valued at a 9.0% cap and
                 assuming no change in G & A, or a 73% LTV at a 8.0% cap with G
                 & A excluded as an operating expense. Including properties
                 under development, the LTV is 63% under the 9.0% cap/100% G&A
                 assumptions, or 53% under the 8.0% cap/0% G&A assumptions.

                 Very simply, even in today's difficult real estate borrowing
                 environment, financing this purchase looks like a no-brainer.

                 FEASIBILITY CONSIDERATIONS: BY-LAW TAKE-OVER IMPEDIMENTS. The
                 Company is a Maryland Corporation. Among the various reasons
                 that the Company, like many other REITs, elected this domicile
                 are the somewhat rigorous and time consuming procedures boards
                 of directors can impose on would-be acquirers to deter a
                 takeover proposal, procedures that are not available in all
                 other states. However, the Company's By-Laws explicitly exempt
                 Mr. Bren and his affiliates from complying with certain of
                 these standards and procedures.

(1) These figures are based on third quarter, 1998 results annualized, valuing
property under development and other assets at book and treating G & A as a
property operating expense. Assuming savings of 50% of G & A and an 8.0% cap
rate, gross asset value increases 14% to $2.17 billion, and the resulting
post-privatization leverage reduces to very easy to obtain 61.1%.

most recent tax exempt financing served to unencumber additional assets.

     INTERESTED STOCKHOLDERS. Maryland General Corporation Law (MGCL) generally
     prohibits certain "business combinations" between an Interested Stockholder
     or an affiliate thereof "for five years after the most recent date on which
     the Interested Stockholder becomes an Interested Stockholder. An Interested
     Stockholder is defined as any person holding 10% or more of the voting
     stock. Customarily, after the five-year period, any such combination must
     be recommended by the vote of the board of directors of the corporation and
     approved by at least (i) 80% of the votes entitled to be cast by holders of
     outstanding voting shares and (ii) two-thirds of the votes entitled to be
     cast by holders of outstanding voting shares of the corporation other than
     shares held by the Interested Stockholder, unless, among other conditions,
     the corporation's common stockholders receive a minimum price for their
     shares and the consideration is received in cash or in the same form as
     previously paid by the Interested Stockholder for its shares."(3)

     SEC filings by the Company go on to say, "The Articles of Incorporation and
     resolutions adopted by the Board of Directors have exempted from these
     provisions any business combination with The Irvine Company, or any
     affiliates of The Irvine Company or Mr. Bren, or any members of the
     immediate family of Mr. Bren and any other person acting in concert or as a
     group with any of the foregoing. All other stockholders are subject to the
     business combination statute."(4) Effectively, Mr. Bren is excused from
     having to secure the affirmative vote of two-thirds of the shares in the
     Company he does not own.

     CONTROL SHARES. MGCL provides that at certain ranges of percentage
     ownership by a potential acquirer, "control shares" are established that
     "have no voting rights except to the extent approved by a vote of
     two-thirds of the votes entitled to be cast on the matter, excluding shares
     of stock owned by the acquirer or by officers or directors who are
     employees of the corporation." With his ownership of common shares
     currently at 17%, Mr. Bren does not have the minimum one-fifth common-share
     ownership percentage that would normally trigger the "control share" rule.
     But again, as reported in Company's SEC filings, "the Company's bylaws
     adopted by the Board of Directors have exempted control share acquisitions
     involving The Irvine Company, or any affiliate of The Irvine Company or Mr.
     Bren, or any members of the immediate family of Mr. Bren and any other
     person acting in concert or as a group. All other stockholders are subject
     to the control share acquisition statute." Mr. Bren, unfettered by the
     control share statute, is now free to convert enough of his interest in the
     Operating Partnership into common shares (under the Exchange Rights granted
     to The Irvine Company) to achieve the requisite voting control of the
     Company, and then would not have these holdings subject to the Control
     Shares provisions and restrictions as specified in the Company's Articles
     of Incorporation.

These provisions make Mr. Bren different from other would-be acquirers of the 
Company.(5) In the event his buy-out proposal is contested then, Mr. Bren

- ------------------------
(3)  These provisions of Maryland law do not apply to business combinations 
     that are approved or exempted by the board of directors prior to the time
     that the Interested Stockholder becomes an Interested Stockholder.

     and Exchange Commission, May 14, 1997.

(5)  Another item in the bylaws which is not especially unique but deserves
     some small mention here because it could potentially have had a role in
     deterring a contested takeover of the Company. The Company's bylaws require
     that "with respect to an annual meeting of stockholders, the proposal of
     business to be considered by stockholders... may be made only by advance
     written notice procedures set forth in the Bylaws." The advance notice
     procedures also apply to the nomination of persons for election to the
     Board. However, Company filings make clear Mr. Bren's considerable
     advantages: "The advance notice provisions are not applicable to The Irvine
     Company," which suggests that competing offers to purchase the Company 
     could potentially never be included in Board business or presented at a
     shareholders' meeting.

                would not have to jump through various requirements that might
                be an annoyance, if not a final deterrent, to others interested
                in taking over the Company. While we have not made a similar
                survey of the by-law provisions of other REITs, we strongly
                suspect that few give similar privileges to their dominant
                shareholder.

                FEASIBILITY CONSIDERATIONS: DEBT COVENANTS. There seems to be a
                good chance that leveraging up might violate certain loan
                covenants, especially leveraging up with secured debt. The
                Company's shelf registration statement speaks of covenants not
                to permit debt to rise above policy limits of 60%. Setting aside
                the problem of determining how a private Company might determine
                debt to market cap ratios, it is probably more relevant to
                consider what would be the consequences of a violation of loan
                covenants. In most cases, the recourse of debt holders is to
                call their loan, not to reset or establish any kind of penalty
                interest rate. A decade ago, in the midst of a collapsing real
                estate market, more than one lender who called a loan after a
                technical default only to find the borrower appearing the next
                day tendering repayment at a 100 cents on the dollar, having
                happily avoided loan-maintenance prepayment penalties in
                repaying an expensive loan. While IAC might not experience as
                large a windfall, there does seem some possibility it might
                easily refinance existing indebtedness at a lesser cost. The
                Company's existing $100 million of unsecured notes, its
                liability most likely to contain covenants which would be
                violated, bears interest at 7.0%, slightly higher than where it
                could likely refinance this debt.

                FEASIBILITY CONSIDERATIONS: DE-REITING AND OTHER TAX ISSUES.
                There are likely a great many tax issues that complicate a
                takeover or privatization, including the possibility that IAC
                could lose its REIT tax-status, and/or that the IAC Operating
                Partnership might terminate for tax purposes. In considering
                these topics we are swimming in dangerous waters where
                tax-sharks more knowledgeable than we have previously taken big
                bites of our flesh. However, to our amateur eye, there seems to
                be important differences in the details that make a
                privatization easier for Mr. Bren than it would be for other
                major holders of other REITs.

                De-REITing seems an inevitability for Mr. Bren and for many
                other would-be acquirers of other REITs. De-REITing means that
                the tax-free pass-through of cash flow would be lost: instead,
                any cash flow passed through what was the IAC REIT would now be
                diluted by taxation. While tax-free pass-through could be
                regained by exchanging the REIT shares for OP Units, such an
                exchange seems unlikely to be deemed a like-kind, and therefor
                tax-deferred exchange. Tax deferral should make no difference
                for Mr. Bren because his basis in newly-acquired REIT shares
                would be $32.50, meaning that the taxable gain and tax liability
                would be minimal to non-existent(6). So far, there is nothing in
                Mr. Bren's position that makes him different from dominant
                shareholders of other REITs.



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

(6) There would be gain only if the value of OP Units were deemed to be greater 
than the $32.50 per share basis. Mr. Bren, might however, have a tax liability 
with respect to shares owned by him to the extent that these shares had a lower 
basis. A minority, but significant part of his holdings are in the form of 
shares.

THE PENOBSCOT GROUP, INC.

                This moves to the second problem, where the facts and
                circumstances of the Company vary significantly from other
                REITs. Assuming that the transaction by which REIT shares are
                replaced by OP units is deemed for tax purposes a transfer of OP
                Units, then, if 50% or more of the interests in the Operating
                Partnership were so transferred, the Operating Partnership might
                terminate for tax purposes, giving all former OP unit holders a
                taxable gain to the extent of difference between the fair market
                value of their OP units and their tax basis in these units. But
                in fact, the Irvine Company holds an approximate 55% interest in
                Irvine Apartment Communities, L.P., the Operating Partnership,
                of which IAC is 45% general partner. Thus a transfer of all of
                the OP units of IAC would not create a tax termination of the
                Irvine Apartment Operating Partnership. In this respect, IAC is
                very different from most other REITs. There may be other ways
                others could skin their respective cats, but these methods seem
                unavailable at most other REITs.

                Very simply, the facts and circumstances unique to Mr. Bren and
                IAC seem to suggest that tax issues and potential costs that
                others might face are absent here.

                SPECIAL INCENTIVES: LAND ISSUES. IAC had now come face to face,
                but not yet come to grips with a zero-sum issue that would pit
                the interests of public shareholders against controlling
                insiders. The issue is, of course, the pricing of land to be
                purchased by IAC from Mr. Bren's Irvine Company, on which IAC
                would develop additional apartment communities. At the IPO,
                under what is known as The Land Rights Agreement, The Irvine
                Company agreed to sell land to the Company for an interim period
                at prices which were estimated to result in a total 10.0% to
                10.5% return on the Company's total investment. The Company's
                rights to buy under this arrangement lapsed with the land
                previously purchased on which 1,884 apartments have been or are
                now being constructed. Thereafter, purchase prices were simply
                not to exceed 95% of appraised value.

                Given history and the interests of parties concerned, value
                seems like a fight waiting to happen, and, but for this
                privatization, likely to have happen very soon. Mr. Bren and the
                Irvine Company would point to the same thing they pointed to in
                announcing the buy-out proposal: "Accretive acquisitions of
                Class A multi-family properties in California are difficult to
                find." This means that cap rates are low and land should be
                priced to reflect a similar low rate of return on investment. In
                fact, we think it likely that they might argue that land on the
                Irvine Ranch should be priced at an even lower cap and return on
                cost than land elsewhere. Other parties, however, might point to
                the land for the 1,884 units bought most recently. Absent some
                prior agreement that these transactions could not be deemed a
                comparable, it could be argued that these are the most direct
                comparable, even if slightly stale.

                The difference, we strongly suspect, is quite large, perhaps 300
                to 400 basis points of return on total investment. A difference
                of 300 basis points could amount to something like $60,000 per
                rental unit.(7) Mr. Bren then faced the pos-

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

(7) The figure of $60,000 is based on a pro forma valuation of the Company at
$127,000 per unit, based on a 9.0% cap rate, and otherwise on the assumptions
more fully described above. If, alternatively, value were premised on a 6.0% cap
rate on the same average per unit NOI, per unit value would be $190,500 per unit
or $63,500 per unit higher. This is an imperfect comparison in that we are
comparing implicit per unit valuation as between 9.0% and 6.0%, as compared to a
more likely range of dispute of between 10.0% and 7.0%, but it

     sibility that he ultimately won the value war, it would destroy the
     economics of IAC which he owns a majority of, while at the same time
     alienating all other holders of IAC shares.(8) There is also the
     possibility that he might have been advised that he wouldn't win the
     valuation argument or that, if he won in the short run, he could expect to
     subject to all sorts of shareholder rights suits, some of which might seek
     punitive damages. The fight was going to have costs, even if it was
     ultimately won. There seems to be value simply in avoiding the fight as is
     achieved by taking the Company private.(9)

     SPECIAL INCENTIVES: COMFORT AS A PUBLIC COMPANY. Donald Bren's role at IAC
     had very few, if any, parallels in the REIT industry. He has a stature as
     an experienced and successful investor over a number of years, a reputation
     similar to that held by Sam Zell, Mort Zuckerman, or Richard Rainwater. But
     he did not choose to take a particularly visible role and rarely attended
     industry functions or in other ways tried to extend the luster of his
     reputation in any which might expand the pricing multiple of IAC shares.
     But although his face was rarely seen, his hand was more visible. We saw
     what appeared as his influence in the turnover of senior officers,
     especially officers who seemed to develop an independent standing or
     stature in the industry.

     First was Dick Moran, who was nominally Executive Vice President and CFO at
     the IPO but held the position of highest visibility initially. In March
     1995, the nominal President as of the IPO, T. Patrick Smith, was gone and
     Mr. Bren stepped in as Acting President. Many people, ourselves included,
     expected Moran to be named President, thus formally acknowledging the role
     he seemed to already have. In May 1995, Steven Albert joined IAC to become
     President; in October 1996 Moran announced his departure and shortly
     thereafter emerged as CFO at Kilroy Realty Corp. Moran was replaced as CFO
     by Jim Mead who had been at IAC in a less visible position for some time.
     Mead then assumed a profile very similar to what Moran had held. By the
     time IAC's 1996 Annual Report was released, Albert was no longer President
     and Mr. Bren was once again, this time with no hyphenated "Acting"
     preceding that title.

     But that tenure was short-lived, and in 1997, William McFarland, who had
     become a director in 1996 and had been associated with Irvine affiliates
     since 1984 and with Mr. Bren previously, became President. Then, in October
     1998, the departure of Jim Mead was announced, as of early 1999.

     Admittedly, what we draw from these patterns is subjective, not conclusive
     and subject to different interpretations. But what we see is a pattern of
     those who have developed an eyeball-to-eyeball sense of trust with the
     investing public not lasting long, while Mr. Bren seems to work his will
     while avoiding the development of any relationship with other shareholders.
     By no means does this suggest that Mr. Bren has or is about to willfully do
     anything to harm the interests of public shareholders. Rather, it suggests
     that he may not have

does nevertheless give some sense of the magnitude of the gap. At $60,000 per
apartment unit the $540 million purchase price would be fully recouped with
9,000 units, roughly 52% of what the Company now has.

(8)  Based on this possibility, an argument could be made that Mr. Bren is 
doing shareholders a favor by buying them out now rather than later.

(9)  On the other hand, if the argument that the 10.0% to 10.5% return is real 
value was to win, there might also be a strong argument that the $32.50 per 
share buyout price is inadequate.

                 developed a sense of being partners with shareholders to the
                 same extent as other, more visible REIT major-domos. In taking
                 IAC private, there is clearly no sense that, for better or
                 worse, we are all in this together.

Is This Good Deal
     A Fair Deal?

                 At the advertised 19.8% compound annual return, it seems that
                 investors have a deal that should elicit few complaints. A
                 19.8% return is considerably better than the NAREIT Equity
                 Total Return Index which produced an IRR we measure at a little
                 over 10% over that same period.(10) But on the other hand,
                 these have been times of strong cyclical recovery. And in
                 California that recovery lagged the rest of the country,
                 meaning that compared to REITs with assets elsewhere, a larger
                 part of the California recovery occurred during this period,
                 and a lesser portion at times preceding this. Thus a 19.8%
                 return could well be merely what is to have been expected from
                 California assets over this time, or maybe even less than what
                 should be expected.

                 No less important, a good return is not necessarily the same
                 thing as a fair return. There will be those who assume that
                 anytime an insider buys from outsiders, the outsiders are being
                 disadvantaged, that the buyer, who can be presumed to know
                 relevant facts than the seller, thinks there is value at the
                 price being paid. Going from raw paranoia to the numbers seems
                 to dissipate the case, but only very slightly.

                 PER UNIT VALUATIONS. At $32.50 per share, the valuation of the
                 Company is roughly $148,000 per apartment unit.(11) This
                 compares to roughly $153,000 per unit cost of recently
                 constructed or now under construction units on the Ranch (which
                 were built on land priced to yield a 10.0% return), or $211,000
                 off the Ranch.(12) Off the Ranch figures are skewed by a
                 119-unit development in Santa Monica, estimated to cost
                 $630,000 per unit, but then again, that Santa Monica asset is
                 included in what Mr. Bren proposes to soon own all of at a
                 valuation of $148,000 per unit.

                 CAP RATE VALUATIONS. Based on trailing NOI, the value seems to
                 imply a 6.8% cap rate.(13) There would be roughly 20 basis
                 points of incremental yield from halving G&A. Adding in the
                 development pipeline at a 10.0% yield, together with halving
                 G&A gives an indicated 8.16% yield. If the development pipeline
                 produces a yield 50 basis points higher (i.e. 10.5%), the
                 composite cap rate moves by a little over 10 basis points to
                 8.27%. And lastly, if forward-looking, rather

(10) We have calculated return on the NAREIT Index using an internal rate of
return over the same time frame.

(11) These calculations reflect (a) the sum of (1) 45.09 million shares and
equivalents times $32.50 each, plus (2) $789 million of liabilities, plus (3)
$144 million of redeemable preferred shares, plus (4) an estimated $333 million
to complete properties now under construction, less (5) $41 million of other
assets, divided by (b) 18,197 units. The figure of 18,197 units includes units
presently under construction. This data is drawn from Company reports as of the
end of its third quarter, 1998.

(12) It might be argued that newer units should have a value above existing
older units. But IAC's old units bring with them one almost unique difference
which positively influences their value: roughly $325 million of tax-exempt
mortgage bond financing bearing interest at a rate of 5.28%. Indeed, as of the
end of 1997, IAC's $704 million of debt bore interest at a weighted average rate
of 6.06%.

(13) This figure is based on $36.6 million of quarterly NOI, annualized to
$150.5 million divided by the value determined for per units calculations above.

                 than trailing NOI were used, as is customary, there might be 10
                 to 50 basis points additional increase in return, especially
                 given the strong movement in rents in this market.

                 It would be interesting to compare these per unit and cap rate
                 valuation benchmarks with the specific examples that brought
                 The Irvine Company to conclude that "Accretive acquisitions of
                 Class A multi-family properties in California are difficult to
                 find." It looks like Mr. Bren may have found a quite accretive
                 acquisition sitting right under his nose.

                 MORE EQUITABLE ALTERNATIVES. The leverage feasibility analysis
                 above seems to argue that, in full fairness, shareholders
                 perhaps should be offered one or two other alternatives to a
                 buyout. The first alternative would be to keep ownership as is,
                 take down similar debt and distribute the proceeds to
                 shareholders. That would of course mean the $540 million would
                 go to all shareholders and thus be less than $32.50 per-share;
                 we estimate it would be roughly $11.98 per-share. And it would
                 have a negative impact on per share FFO which can be estimated
                 at a reduction of roughly $0.84 per year.

                 While many shareholders might find this a not altogether
                 attractive alternative, in a roundabout way, thinking about
                 this possibility brings up another potential solution to the
                 problems that seem to have brought Mr. Bren to propose a buyout
                 as being in the best interests of the Company.(14) Part of the
                 stated reason for going private is to be able to retain
                 capital. But by leveraging up to fund a privatization, there is
                 actually going to be less cash flow available, even if all of
                 it could be retained and reinvested. Despite this inconsistency
                 with Mr. Bren's stated goals, the transaction is attractive to
                 him, largely because of a presumed cost of the capital
                 necessary to effectuate the buyout of 7.0% or less. Thus it
                 might more in the interest of shareholders to leave ownership
                 unchanged, but increase its leverage to the extent of $540,000
                 million and invest those proceeds in the opportunities Mr. Bren
                 sees as being lost to the present obligation to distribute all
                 cash flow; then shareholders in addition to Mr. Bren might
                 enjoy the benefits of higher leverage at prevailing rates. Or
                 stated another way, there is more than one way to deal with the
                 problems Mr. Bren purports to be solving and many shareholders
                 might find that solution preferable to being bought out at
                 $32.50 per share.

   Probabilities 
       Elsewhere Very few other REITs seem to have similar facts and
                 circumstances to make a take-over by dominant insiders likely.
                 In our coverage universe, REITs where insiders hold a large
                 percentage of effective ownership of the consolidated
                 enterprise include Boston Properties (19.4% owned by the
                 chairman, management and their families), Cousins (19.2%),
                 Crescent (13.0%), CBL (27.9%), General Growth (17.2%), Simon
                 (23.6%, including DeBartolo family interests), Urban (38.0%),
                 and Taubman (17.7%).(15) All of these are some distance from

(14) At this point the "Company" seems to have taken on a metaphysical quality
wholly separate from the interests of its various shareholders. It seems to us a
more constructive approach would be to view the interests of the Company as
equivalent to the aggregate interest of these owners.

their most recent proxy and shares and equivalents as of the third quarter of
1998.

THE PENOBSCOT GROUP, INC.

                     level owned by Mr. Bren. Existing debt as a percent of the
                     fair market value of assets, using a 9.0% cap rate on
                     trailing NOI annualized, is generally higher than IAC's
                     level. At Boston Properties, liabilities equal 52% of FMV
                     calculated on this method, at Cousins 31%, at Crescent 42%,
                     at CBL 66%, at General Growth 78%, at Simon 94%, at Taubman
                     58% and at Urban 70%. Using an 8.0% cap rate, the mall
                     REIT's leverage is lower, 59% for CBL, 70% for General
                     Growth, 83% for Simon, 52% for Taubman, and 62% for Urban.
                     Very simply, the likelihood of the dominant shareholders of
                     these REITs following Mr. Bren's example seem quite low.
                     The most plausible exception seems to be Cousins, where
                     there may also be hidden value in non-income producing land
                     holdings.

                     In a sense, this analysis seems to turn the conventional
                     wisdom that larger ownership interests by management are
                     better than smaller. But as we see it the correct
                     conclusion is more a refinement than a refutation of
                     conventional wisdom. In effect a corollary should be added
                     to conventional wisdom: when management's interest is so
                     large as to give them effective unilateral control, it is
                     good to be attentive to all those signals which indicate
                     whether such a dominant shareholder views other
                     shareholders as either his partners, or as a convenient
                     source of the interim financing for his company.

 Tying This Deal to
          Our Macro
Perspectives Stated
          Elsewhere
                     Our regular readers are no doubt aware of our recent 
                     speculations regarding the possibility of deflation in 
                     real estate.(16) In those ruminations, we have argued that 
                     certain types of property might be spared the negative 
                     effects of deflation and instead experience land 
                     appreciation to arrive at full equilibrium between, on one 
                     hand, supply and demand as reflected in rents and, on the 
                     other hand, replacement cost as factored by the cost of 
                     capital, the long-term debt portion of which has recently 
                     declined significantly and appears likely to remain low. 
                     We argued that the more favorable scenario is more likely 
                     in circumstances where the providers of space have some 
                     pricing control, some ability to avoid the other scenario 
                     characterized by real declines in rents rather than land 
                     appreciation. While we have also characterized urban 
                     properties as more likely to perform in a manner 
                     consistent with the land appreciation scenario, not all 
                     urban areas would enjoy this pattern and not all non-urban 
                     would not. One of the more likely locations to perform 
                     well is the Irvine Ranch, a prospect that argues that it, 
                     or more specifically, the Company should be valued 
                     differently than real estate in other locations. It also 
                     means that IAC might be especially missed by investors and 
                     those of us who like to try to figure out what is really 
                     going on.

               [REALTY STOCK REVIEW FRONT PAGE, DECEMBER 4, 1998]

           Market Analysis of REITs & Real Estate Operating Companies



WATERSHED OR NO BIGGIE?

     After the market closed on December 1, The Irvine Company, a private real
estate entity controlled by Donald Bren, announced an offer to buy the
approximately 16.6 million shares of Irvine Apartment Communities that it
doesn't already own for $32.50 per share. Simply put, in a deal valued at $540
million, Bren is proposing to take private the company that he took public in
December 1993 at $17.50 per share. The Irvine Company hopes to have the deal
approved by the end of this year.

     The Irvine Company is the largest current stockholder of IAC. As of
December 1, it held approximately 17% of the outstanding common shares. It also
owns approximately 55% of the partnership interests of Irvine Apartment
Communities, L.P. of which IAC is a 45% general partner. In all, Bren owns an
approximate 63% economic interest in IAC. Bottom line: After roughly five years
in the public fishbowl, Bren has apparently decided that he wants it all!

     In its press release announcing the proposal, The Irvine Company stated
that the bid is not subject to a financing contingency. In addition, The Irvine
Company noted that the existing debt and preferred stock of Irvine Apartment
Communities, L.P., IAC's operating partnership, will remain outstanding and are
not expected to be affected by the proposed transaction.

     We have mixed feelings about Bren's offer. On one hand, Bren is paying a
"fair" price for IAC (more on that subject, in a bit). On the other hand, though
IAC has had its ups and downs -- a mind-boggling number of senior level
management changes hasn't helped matters -- it is the sort of company we'd like
to see in the public arena. Furthermore, it has delivered solid returns for
investors, and our view is that even "better times" lie ahead.

                     [GRAPH SHOWING STOCK PRICE AND VOLUME]

BIG QUESTIONS

     Is Bren the first of many to pack it in and take his REIT private? We 
don't think so. First, we never thought Bren's heart was really in being 
public. (He shuns the spotlight.) His attitude toward the public market from 
the outset was tentative, at best. We 


<PAGE>   59
                                                                           DRAFT


suspect Bren took IAC public -- and thought long and hard about taking other
pieces of The Irvine Company public -- not because he, like a Sam Zell, saw the
"equitization" of real estate as a long-term goal, but rather because it solved
shorter-term issues. (Though we suspect that had things gone differently he
might have stayed around, at least a while longer.) So, as we see it, Bren's
decision doesn't say anything about the resolve of those who came public over
the past five years or so to remain public.

     Second, though some observers suggest the price Bren is offering -- roughly
a 20% premium to what IAC was going for before the announcement -- confirms that
REITs are under-valued by the market currently, we don't agree. REITs may be
cheap on a relative and possibly even on an absolute basis, but whatever price
Bren has to pay to get the shares of IAC he doesn't already own, it reflects the
uniqueness of the situation. Extrapolating from what Bren is willing to pay to
the market generally isn't warranted, though it would be nice to be able to do
so.

IAC RECAP

     According to IAC's latest 10-Q (filed on November 11), the company had
20,129,873 common shares outstanding as of October 31. It owned 62 apartment
communities (it owned 42 when it came public) with 16,029 apartment units. (The
overwhelming majority of those are located in Orange County, California on the
Irvine Ranch.) It had 2,729 apartment units under development. The company broke
ground on its first apartment community, off the Irvine Ranch in Northern
California's Silicon Valley, in May of last year.

     IAC reported third quarter FFO/share (diluted) of 60 cents vs. 51 cents in
the year-ago period. (It's 3Q98 FFO/share was a penny or two ahead of most
estimates, by the way.) FAD (funds available for distribution) was 57 cents vs.
49 cents in the year-ago period. (Weighted average shares/units outstanding was
45.157 million.) Same-store results -- 48 properties with 13,451 units owned and
stabilized before 1997 -- experienced a 10.1% increase in net operating income
over the year-ago period ($32.5 million vs. $29.5 million). Average monthly rent
went from $1,119 to $1,171 per unit. Physical occupancy went from 93.8% to
94.1%.

ISSUES TO WEIGH

     Bren isn't trying to steal the company, but he's not overpaying either. His
offer of $32.50 per share is, as noted, well above the price IAC was changing
hands at immediately prior to the announcement. It's also a premium over "our
consensus NAV of $24.43 per share." (The high end of the consensus is in the
neighborhood of $28 to $29 per share.) However, recent conversations with
non-REIT folks in Orange County who are familiar with IAC's portfolio and local
economics lead us to believe that in some instances the cap rates being used to
value the portfolio are on the high side. (Something in the low 7% range seems
right to us.) More important, however, when IAC came public there was a good
deal of controversy about its valuation, generally, and specifically about the
company's unique development story. So, though an investor who bought IAC at the
IPO and held on to it has done well, we believe Bren's offer doesn't fully
reflect the "future" value that shareholders paid for when they bought IAC. It's
tough to nail down a hard number, though if IAC develops, say, $150 to $200
million in apartments per year and earns a 20% to 25% development profit on that
investment, it would add at least another $30 million to the mix annually. An
offer in the $34 to $35 range better reflects not only IAC's current value, but
also gives investors who bought the development story's potential something for
their vote of confidence in Bren.

     It will be interesting (no, fascinating) to see how IAC's senior executives
and independent directors deal with Bren's offer. As one buy-sider put it, "Bren
casts a mighty large shadow, especially in Southern California." (This is yet
another test of corporate governance in the REIT sector.) Again, we wouldn't
accuse Bren of trying to steal the company, but given what he said when IAC came
public about the development story, we'd feel a lot better if he sweetened his
offer by $1.50 to $2.50 a share.

     When we went to press, IAC was changing hands at $31 5/8 per share.
Assuming a transaction at $32.50 per share -- and counting IAC's fourth quarter
dividend of 38.5 cents per share -- an investor could earn roughly a 4% total
return in a month. Not too shabby! Moreover, in our view, there's at least a
50/50 chance that Bren will sweeten his offer. For those reasons, we're raising
our rating on IAC from DCA to a BUY.

KEY POINTS

- -We have downgraded our rating on Irvine To Neutral from Outperform.

- -Irvine Apartment Communities' stock price rose 15% to $31-9/16 from $27-3/8 on 
Wednesday December 2, 1998 after the announcement that the privately held 
Irvine Company offered $32.50 for the 16.6 million shares outstanding that it 
does not own.

DETAILS

*WE ARE DOWNGRADING OUR RATING TO NEUTRAL FROM OUTPERFORM. The board of Irvine 
Apartment Communities (IAC) received a letter from TIC Acquisition LLC, a 
subsidiary of The Irvine Company (TIC) proposing to acquire the outstanding 
shares in the REIT for $32.50 per share. The stock closed yesterday at 
$31-9/16, which is within 3.0% of the offered price. The shares traded up 15% 
from the prior day's close of $27-3/8. TIC management indicated they would like 
to close during the first quarter of 1999. We think a competing bid is 
unlikely. The price would have to move beyond $36 to warrant an Outperform 
rating. Consequently, we have downgraded our rating to Neutral.

*THE IRVINE COMPANY OWNS A MAJORITY OF THE OPERATING PARTNERSHIP. The Irvine 
Company is a privately held real estate firm that owns the Irvine Ranch in 
Orange County, California. The ranch is the largest master-planned community in 
the country. TIC owns 55% of the partnership interests of Irvine Apartment 
Communities, L.P. Irvine Apartment Communities, the REIT, owns the remaining 
45%. However, TIC also owns 17% of the stock in the REIT, giving TIC an overall 
63% economic interest in the operating partnership.

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

*A SUBSIDIARY OF THE IRVINE COMPANY MADE THE $32.50 PER SHARE PROPOSAL. The
proposal was made on December 1, 1998 to the Board of Directors of IAC with a
response requested by December 31, 1998. Now, we believe the board has to have
its committee evaluate the proposal and provide an answer.

*WE DO NOT EXPECT COMPETING OFFERS. One of the attractions of investment in IAC
was its exclusive right to develop multifamily communities on the Irvine Ranch.
Management of TIC indicated to us that such a right might not transfer to
another acquirer of the REIT, which could make such an investment much less
appealing. Also, the $32.50 per share price offered represents 12.7x our 1999
FFO estimate of $2.55 per share. Such a price would likely be dilutive to most
other REITs.

We had been carrying a $31 per share net asset value (NAV) for IAC. Thus, a
price of $32.50 appears reasonable. We derived our net asset value using an 8.0%
cap rate on fourth quarter expected net operating income. We calculate that it
would take a 7.75% cap rate to reach the $32.50 per share level. In addition, a
price-to-FFO multiple of 12.7x our 1999 estimate, or 13.7x using our AFFO
(adjusted FFO, or FFO less recurring capital expenditures) estimate is well
beyond the upper end of the range we are carrying for our multifamily universe.
TIC management indicated that the offered price represented a 21% premium to the
stock's closing price prior to the offer.

*TIMING IS STILL UNCERTAIN. Management of TIC indicates it would likely pursue a
merger with the REIT or a tender offer. A merger could take much longer owing to
requirements for the mailing of a proxy, setting a shareholder meeting, and
conducting the vote. A tender offer, however, could proceed much more quickly if
the requisite number of stockholders tender their shares.

*TIC HAS FINANCING LINED UP. TIC delivered a no financing contingency offer to
IAC's board. The funds are immediately available to close on the transaction.
TIC has a $350 million acquisition term loan from the Bank of America and other
cash and credit facilities available to fund the $540 million needed to purchase
16.6 million shares at $32.50. If successful, TIC would leave the operating
partnership intact and, therefore, would not have to retire its outstanding debt
or preferred stock.

*TIC OUTLINED SEVERAL REASONS FOR THE TRANSACTION. Among them, it believes it
can access capital on a more cost efficient basis as a private company. Raising
equity has become a more expensive proposition for REITs, including IAC, at
current prices. Also, the dividend distribution requirement limits the amount of
capital left to reinvest in the business and fund development.

For a more detailed discussion on how this may affect other multifamily REITs,
see our First Call note dated December 2, 1998.

Real Estate (I/REA): IAC COULD BE FIRST MULTIFAMILY REIT TO GO PRIVATE
Steven G. Bloom, CFA (212) 761-6284                   Date: December 2, 1998 
                                                     Type: Industry Overview

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

KEY POINTS

- -The Irvine Company plans to take Irvine Apartment Communities, a multifamily 
REIT, private at $32.50 per share. The decision to go private points to some 
REIT limitations like the inability to retain and the high current cost of 
raising capital.

- -In most ways, the situation is unique to this REIT. However, it does confirm 
our belief that many multifamily REITs are trading at or below net asset value 
(NAV).

- -In our universe, Berkshire Realty (BRI, $10, Outperform) and Summit Properties 
(SMT, $17, Outperform) are trading about 20% below our estimated NAV.

- -We think the better-managed companies with exposure to strong markets ought to 
trade at a slight premium to NAV. Our top picks include Avalon Bay 
Communities (AVB, $33, Strong Buy) and BRE Properties (BRE, $24, Strong Buy).

DETAILS

IRVINE APARTMENT COMMUNITIES COULD GO PRIVATE. The Irvine Company (TIC), which 
owns a majority 55% interest of Irvine Apartment Communities LP and 17% of the 
shares of Irvine Apartment Communities Inc. (IAC, a real estate investment 
trust), announced an offer to IAC's board to acquire the remaining 16.6 million 
shares of IAC it does not already own. IAC is unusual in that the REIT is a 
minority owner of the operating partnership. TIC intends to pay $32.50 per 
share. The shares closed on December 1, 1998, just prior to the announcement, 
at $27 3/8.

THE DECISION POINTS TO SEVERAL CHALLENGES FACING MULTIFAMILY REITS TODAY. The 
Irvine Company offered several reasons for its decision. On one hand, it 
believes a private company is better situated to handle development risks. On 
the other, raising new capital has become expensive. The decision to take the
REIT private points to some of the limitations affecting multifamily REITs 
today. We think it also confirms our belief that many companies are trading at 
or below net asset value.

In general, distributing at least 95% of net income, and in most cases, 70-80% 
of cash flow after reserving for recurring capital expenditures, leaves little 
in the way of retained earnings to reinvest in the company. With many companies 
trading at or below net asset value, selling new equity can be expensive. 
Combined with historically low leverage levels, many multifamily REITs have 
lost their low cost of capital advantage, especially if capital continues to 
flow to private players.

WHILE GOING PRIVATE MAY SERVE AS A CATALYST FOR THE SECTOR. . .IAC is the 
first company in our multifamily universe to commence with plans to go private. 
To the degree management has stepped up and indicated it sees more value in the 
REIT than the public markets give credit for, investors may pay greater 
attention to the sector. Most of the companies in our universe are trading at 
or below our estimate for net asset value. There are two stocks we have rated 
Outperform that are trading approximately 20% below our estimated net asset 
value. They are Berkshire Realty (BRI, $10) and Summit Properties (SMT, $17).

 . . . IAC WAS A UNIQUE SITUATION. IAC was the only company we track whereby the 
REIT owned a minority interest in the operating partnership. Moreover, the 
Irvine Company appears very well capitalized and clearly has the

wherewithal to carry out the transaction. By leaving the operating partnership
intact it does not have to refund the partnership's debt and preferred
securities. Even if another management team wanted to take its company private,
debt costs may still be prohibitive.

WE DERIVE A 7.75% CAP RATE FOR THE TRANSACTION. At $32.50 per share, we believe
the company's income is being valued at approximately a 7.75% cap rate. We had
used an 8% cap rate in coming up with our $31 net asset value (NAV). Assets in
California are generally valued more highly than other areas of the country
given favorable demographics and high barriers to new construction. IAC was
particularly interesting because the Irvine Company owns the Irvine Ranch in
Orange County, which is the largest master planned community in the U.S. The
REITs had an exclusive right to develop multifamily communities on the ranch,
effectively giving it a local monopoly on new development. We presume that the
Irvine Company saw even greater value to the REIT or future development to
justify the price offered for the shares.

WE BELIEVE BETTER-QUALITY COMPANIES OUGHT TO TRADE AT PREMIUMS TO NAV. We think
the better-managed companies with strong balance sheets, low payout ratios, and
exposure to attractive markets ought to be able to trade at a premium to NAV.
Alternatively, when a company's strategy is not embraced by investors the stock
may trade below NAV. Over time, the difference may determine which multifamily
REITs can issue equity on a cost-effective basis and continue to grow through
acquisitions and development compared to those that may be precluded from
raising cheap capital.

We maintain our cautious near-term outlook for companies with exposure to
markets that may experience oversupply problems during 1999 such as Dallas,
Houston, and Orlando. While we expect apartment starts to slow by year-end and
through the early part of next year, recent increases in starts could contribute
to market weakness during 1999 as new communities are completed. We think the
supply outlook ought to improve in 2000.

TOP PICKS: AVB AND BRE. We would continue to focus on companies with exposure 
to markets that have been undersupplied and with high barriers to entry. Our 
top picks include Strong Buy rated Avalon Bay Communities (AVB, $33) and BRE 
Properties (BRE, $24). Avalon Bay has a national presence through exposure to 
West Coast, Midwest, Mid-Atlantic, and Northeast markets. BRE's portfolio is 
located primarily in West Coast markets.

         IAC TO GO PRIVATE; DONALD BREN OFFERS $32.50 PER COMMON SHARE

WE ARE LOWERING OUR INVESTMENT RATING ON IRVINE APARTMENT COMMUNITIES, INC. TO

TARGET PRICE. HOWEVER, GIVEN THE APPRECIATION IN THE SHARE PRICE IN REACTION TO 
THE ANNOUNCEMENT, THE PROPOSAL OFFERS ONLY MODEST UPSIDE FROM THE CURRENT SHARE 
PRICE, PRECIPITATING OUR RATING CHANGE. GIVEN THE IRVINE COMPANY'S CONTROLLING 
POSITION IN THE REIT AND OVER THE IRVINE RANCH, WE WOULD NOT EXPECT ANY 
COMPETING OFFERS. WE BELIEVE THAT CURRENT SHAREHOLDERS SHOULD HOLD IAC SHARES 
AND REINVEST THE CASH PROCEEDS IN THE SHARES OF ESSEX PROPERTY TRUST, INC. (ESS 
- - $31 1/8, BUY) AND BRE PROPERTIES, INC. (BRE - $24 9/16, BUY), THE TWO 
REMAINING WEST COAST MULTIFAMILY SECTOR PURE PLAYS.

o    THE IRVINE COMPANY TO TAKE IAC PRIVATE - Yesterday, TIC Acquisition LLC, a
     wholly owned subsidiary of The Irvine Company, announced an offer to
     purchase the 16.6 million common shares of IAC that it currently does not
     own for $32.50 per share in cash, for a total purchase price of
     approximately $540 million. IAC management stated that conditions facing
     REITs have become increasingly difficult and that it believes that a
     private company is better suited to operate in such an environment.

o    TRANSACTION ANTICIPATED TO CLOSE WITHIN TWO TO THREE MONTHS - Given the
     Irvine Company's controlling ownership position in the REIT and over the
     Irvine Ranch, we do not expect any competing offers. Through its ownership
     of 17% of the outstanding common shares and 55% interest in the operating
     partnership, The Irvine Company holds a 63% economic interest in IAC. The
     Irvine Company also controls the land and, therefore, development on the
     Irvine Ranch, making the operation of the REIT by an unfriendly third party
     economically unfeasible. The proposal does not include a tender and IAC's
     Board of Directors has until December 31, 1998 to respond to the proposal.
     We expect the deal to be completed within two to three months.

* FAIR PRICE TO IAC SHAREHOLDERS; OPPORTUNITY TO TRADE INTO REMAINING WEST COAST
  APARTMENT PLAYS -- We believe that the $32.50 share price offer, a 21% premium
  over the previous day's closing price, is a fair price for several reasons:
  (i) it represents a small premium (1/8) over the stocks all-time high of $32
  7/16; (ii) at 12.7x our 1999 FFO/share estimate, it represents a significant
  premium over the peer group average multiple of 9.8x; and (iii) it is above
  our $32 price target. We believe that current shareholders should Hold IAC
  shares and reinvest the cash proceeds in the shares of Essex Property Trust
  (9.9x our 1999 FFO/share estimate of $3.15) and BRE Properties (10.2x our 1999
  FFO estimate of $2.40), the two remaining West Coast multifamily sector pure
  plays.

                           (Not Part of This Exhibit)

Pursuant to the requirements of Rule 13e-3 of the Exchange Act, the following
preliminary analysis is being filed as an exhibit to the Schedule 13E-3. The
following preliminary analysis was prepared by Morgan Stanley and discussed with
the Special Committee on January 14, 1999. The information contained in the
preliminary analysis was prepared as a negotiating tool and to provide the
Special Committee with some background information with respect to possible
alternatives in connection with the offer made by TIC Acquisition LLC. It is
important to note that neither the due diligence nor the analysis performed by
Morgan Stanley reflected in the above referenced draft was complete at the time
the preliminary draft was prepared and it was not intended to be relied upon by
the Special Committee or any third parties, including the Shareholders. The
Special Committee was aware of the status of and the preliminary nature of the
draft and the fact that it was not to be relied upon. The preliminary analysis
was prepared as of January 14, 1999 and reflects information made available to
Morgan Stanley prior to such date. Therefore, Morgan Stanley's preliminary
analysis performed as of January 14, 1999 does not and did not reflect the final
views of Morgan Stanley with respect to Morgan Stanley's valuation of the
Company or an opinion as to the fairness of the proposed transaction as of the
date it was provided to the Special Committee.

BACKGROUND / CHRONOLOGY

- -    December 15, 1988: Morgan Stanley met with management and local consultants
     of Alpha to discuss a number of topics:

     -    Review of business plan

     -    Review of projections / company model

     -    Discussion of market conditions and market studies

- -    December 22, 1998: Alpha's special committee and its financial and legal
     advisors met to discuss the Proposal, consisting primarily of:

     -    Analysis of Alpha

     -    Alternatives potentially available to Alpha

     -    Structural considerations

- -    December 30, 1998: The financial advisors of Alpha and Beta met to discuss
     valuation analyses of Alpha that each had performed. In addition, Morgan
     Stanley requested that all information considered by Beta or its advisors
     in valuing Alpha be provided to Morgan Stanley

     which Morgan Stanley believes that assumptions made by NationsBanc in its
     valuation of Alpha do not adequately reflect the value of Alpha

- -    January 8, 1999: Materials received from NationsBanc per request dated
     December 30, 1998 (index included)

                                EXECUTIVE SUMMARY
                                   (CONTINUED)

FINANCIAL ANALYSIS

- -    In evaluating the Proposal, we have attempted to estimate a valuation range
     for the Company by the application of several different valuation
     methodologies

     -    Net asset value: Looks at the current value of the Company's assets on
          an asset sale basis, netting out debt and preferred to estimate common
          equity value. This is analogous to liquidation value, although debt
          and preferred penalties to retire are not included nor is the time
          value of any disposition program

     -    Discounted cash flow: Relies on projections, based on several
          scenarios, of the Company's performance to estimate a going concern
          value. Includes dividend discount model, free cash flow model, and
          leveraged recapitalization analysis 
 
    -     Comparable company analysis: Estimates the value of the Company based
          on trading levels of selected peers, without implying that it has
          traded or would trade similarly. It is important to note that no good
          comparable company exists

     -    Ability-to-pay: Estimates the value of the Company if it were acquired
          by another public apartment company based on a variety of assumptions
          as to the acquirer's acceptable level of earnings accretion or
          dilution

     -    Comparable multifamily transactions: Looks at other transactions that
          have occurred in the sector. As these (a) were typically mergers of
          equals and (b) involved stock as consideration as opposed to cash,
          they are not considered sufficiently comparable so as to allow
          meaningful value conclusions to be drawn

     -    Comparable squeeze-out transactions: Reviews premiums paid in prior
          squeeze-out transactions. Although a resulting range is shown, the
          applicability is limited because of variations, among other factors,
          in the rights of each side and the pre-offer public trading valuation
          relative to a theoretical intrinsic value

     -    Wall Street's view: Synopsis of statements as to the value of the
          Company published by research analysts before and after publication of
          the Proposal

                               KEY NAV ASSUMPTIONS

STABILIZED PROPERTIES

The 56 stabilized properties including recent acquisitions Park Place, Hamptons
and Rancho Santa Fe, were placed into three tiers based upon:

           - year built       - average rent
           - location         - quality

Each tier was ascribed a cap rate range:

          Tier I     Newer properties in prime locations with highest rents.
                     Cap rate range: 7.25% - 7.75%

          Tier II    Late 1980s product including the student housing
                     properties. Cap rate range: 7.5% - 8.0%

          Tier III   Older product, lower average rent. Cap rate range:
                     7.75% - 8.25%

Cap rates were applied to 1999E NOI
These ranges were evaluated and deemed appropriate in light of cash flow yields
(NOI less capital reserves) which would be about 96% as high
Net operating income was calculated based on:

          -    4th quarter forecasted NOI was increased at a quarterly
               compounded growth rate
          -    Operating margin is assumed to be 70% and annual revenues are
               increased 7% to 12%
          -    Expenses are escalated at 3%

PROPERTIES UNDER DEVELOPMENT

Properties under development were valued as follows:

          -    DCFs were performed for each property from l/l/99 until
               stabilization

          -    Cap rates were applied ranging from 7.25% to 8.25% to compute
               terminal value at stabilization

          -    Discount rates of 12% to 16% were utilized

LAND RIGHTS AGREEMENT

The Land Rights Agreement was calculated utilizing two methodologies:

          I.   Below-market land acquisition prices 
               Assuming the land is being transferred to Alpha at prices below
               what a third party would pay, the value differential was
               calculated given Alpha pays 95% of appraised value, with a total
               discount of 5% to 15% compared to a third party 
               The agreement was valued based upon the following variables:
<TABLE>
<S>                                <C>                       <C>                  <C>
               Discount to market: 5% to 15%                 Average cost / unit: $50,000 to $75,000
               Units Developed:    1,000 to 1,500 per year   Discount Rates:      12% to 15%
</TABLE>

          II.  Value of Non-Compete 
               The value differential between Alpha having the Agreement and the
               choice to develop, versus a third party developing on-ranch 
               The agreement was valued based upon the comparison of two DCF
               analyses:
               1.   Third party developer develops on-ranch, rents increase 7%
                    in 1999, 4% in 2000, and 3% thereafter
               2.   Alpha stops developing on-ranch, rents increase over time,
                    at rates of 1% to 2% above rates for Analysis 1

                    Discounted Cash Flow Analysis Assumptions

Basic Assumptions
 - Rent growth in 2001 and thereafter is assumed to be 3% (see below for 1999
   and 2000).
 - Expenses grown at 3% annually.
 - Interest rate assumed to be 7.5% on all future debt.
 - Development continues according to company projections but 1999 acquisitions
   have been omitted. 
 -Rent growth and occupancy for off-ranch properties left at company projections
   (rent growth ranging from 4% to 5%, occupancy averages 95%).
 - Other income consists of income derived from projects such as the utility
   billing service (RUBS) and the appliance rental service as well as late
   charges and parking fees. For developments it is assumed to be 0.5% of total
   gross scheduled rent and for existing properties it grows at 3% annually, as
   per company projections. Also includes income derived from revenue sharing
   projects such as cable and telecommunications as well as application,
   termination, and pet fees, laundry service, and damage receipts. For
   developments it is assumed to be 1% of total gross scheduled rent and for
   existing properties it grows at 3% annually, as per company projections.
 - For cases with current capital structure, company's projected dividends
   increased by 100% of FFO percentage increase in 2000 through 2003 (FFO payout
   ratio averages 69% in 1999 to 2003).
 - For cases with leveraged capital structure, 50% of FAD paid quarterly as
   dividends.
 - Shares outstanding: 45,330,741 (assumes options converted by treasury method
   using $35.00 per share value).

Variables
  - Occupancy: targeted stabilization occupancy of on-ranch properties is 96%.
  - 1999 rent growth: on-ranch property rent growth in 1999 is 7% (Conservative
    Case) and 12% (Chairman's Case).  
  - Rent growth for 2000 according to Company projections (4%) except in
    Chairman's Case where rate is 8%. 
  - G&A for leveraged scenarios is 55% of Company projections, as per separate
    schedule.
  - In leveraged recapitalization scenarios, Beta is assumed to borrow $550 MM
    to buy shares of Alpha at $32.50 on 1/l/99.

                              Transaction Rationale


                                     ALPHA

- -    Attractive price relative to numerous valuation methodologies

- -    Provides shareholders approximately 20% compounded annual return, including
     dividends, for shareholders who purchased shares in IPO

- -    Future performance and valuation of Alpha would likely be negatively
     impacted given conflicts of interest with Beta

- -    Financing development plan may be difficult, and would be if current equity
     market conditions continued

- -    Management uncertainty prior to, and after, Proposal

- -    Delivery of multi-family parcels on the ranch may be slowed

- -    Public real estate market has softened as investors have left the market


                                      BETA

- -    100% control and ownership of Alpha

     -    receive all of projected earnings and cash flow growth

     -    control of management and all decision-making

     -    alignment of Alpha's and Beta's interest should maximize combined
          valuation

     -    capture full development profit and the right to develop on the Irvine
          Ranch

- -    Finance company better without public company debt limitations

     -    access less expensive, private sources of capital

- -    Eliminate public scrutiny and disclosure requirements

     -    Also reduces overhead associated with a public company

STABILIZED PROPERTIES

The 56 stabilized properties including recent acquisitions Park Place, Hamptons
and Rancho Santa Fe, were placed into three tiers based upon:

      - year built                               - average rent

      - location                                 - quality

Each tier was ascribed a cap rate range:

      Tier I   Newer properties in prime locations with highest rents. Cap
               rate range: 7.25% - 7.75%

      Tier II  Late 1980s product including the student housing properties.
               Cap rate range: 7.5% - 8.0%

      Tier III Older product, lower average rent. Cap rate range: 7.75% - 8.25%

Cap rates were applied to 1999E NOI

These ranges were evaluated and deemed appropriate in light of cash
flow yields (NOI less capital reserves) which would be about 96% as high

Net operating income was calculated based on:

      - 4th quarter forecasted NOI was increased at a quarterly
        compounded growth rate 

      - Operating margin is assumed to be 70% and annual revenues are 
        increased 5% to 9% 

      - Expenses are escalated at 3%

PROPERTIES UNDER DEVELOPMENT

Properties under development were valued as follows:

      DCFs were performed for each property from 1/1/99 until stabilization
      Cap rates were applied ranging from 7.25% to 8.25% to compute
      terminal value at stabilization 

      Discount rates of 12% to 16% were utilized

LAND RIGHTS AGREEMENT

The Land Rights Agreement was calculated utilizing two methodologies:

        I.  Below-market land acquisition prices

        Assuming the land is being transferred to Alpha at prices below what a
        third party would pay, the value differential was calculated given Alpha
        pays 95% of appraised value, with a total discount of 5% to 15% compared
        to a third party. The agreement was valued based upon the following
        variables:

<TABLE>
<S>                          <C>                      <C>                  <C>
        Discount to market:  5% to 15%                Average cost / unit: $50,000 to $75,000
        Units Developed:     1,000 to 1,500 per year  Discount Rates:      12% to 15%
</TABLE>

        II. Value of Non-Compete

            The value differential between Alpha having the Agreement and the
            choice to develop, versus a third party developing on-ranch. The
            agreement was valued based upon the comparison of two DCF analyses:

        1. Third party developer develops on-ranch, rents increase 7% in 1999,
           4% in 2000, and 3% thereafter

        2. Alpha stops developing on-ranch, rents increase over time, at rates
           of 1% to 2% above rates for Analysis I

                    Discounted Cash Flow Analysis Assumptions

Basic Assumptions

     -    Rent growth in 2000 is assumed to be 4%.

     -    Rent growth in 2001 and thereafter is assumed to be 3%.

     -    Expenses grown at 3% annually.

     -    Interest rate assumed to be 7.5% on all future debt.

     -    Development continues according to company projections but 1999
          acquisitions have been omitted.

     -    Rent growth and occupancy for off-ranch properties left at company
          projections (rent growth ranging from 4% to 5%, occupancy averages
          95%).

     -    Other income consists of income derived from projects such as the
          utility billing service (RUBS) and the appliance rental service as
          well as late charges and parking fees. For developments it is assumed
          to be 0.5% of total gross scheduled rent and for existing properties
          it grows at 3% annually, as per company projections. Also includes
          income derived from revenue sharing projects such as cable and
          telecommunications as well as application, termination, and pet fees,
          laundry service, and damage receipts. For developments it is assumed
          to be 1% of total gross scheduled rent and for existing properties it
          grows at 3% annually, as per company projections.

     -    Shares outstanding: 45,330,741 (assumes options converted by treasury
          method using $35.00 per share value).

Variables

     -    Occupancy: targeted stabilization occupancy of on-ranch properties is
          95% for conservative case, 96% for other cases.

     -    1999 rent growth: on-ranch property rent growth in 1999 is 5% to 9%.

     -    G&A for leveraged scenarios is 55% of Company projections, as per
          separate schedule.

     -    In leveraged recapitalization scenarios, Beta is assumed to borrow
          $550 MM to buy shares of Alpha at $32.50 on 1/l/99.

     -    For conservative case with current capital structure, Company dividend
          projection assumed.

     -    For other cases with current capital structure, company's projected
          dividends increased by 100% of FFO percentage increase in 2000 through
          2003 (FFO payout ratio averages 69% in 1999 to 2003).

     -    For cases with leveraged capital structure, 50% of FAD paid quarterly
          as dividends.

Board of Directors
Irvine Apartment Communities
550 Newport Center Drive, Suite 300
Irvine, CA 92660

MEMBERS OF THE BOARD:

We understand that Irvine Apartment Communities (the "Company"), The Irvine 
Company ("TIC") and TIC Acquisition LLC, a wholly owned subsidiary of TIC 
("Acquiror"), propose to enter into an Agreement and Plan of Merger (the 
"Merger Agreement") which provides, among other things, that each outstanding 
share of common stock, par value $.01 per share (the "Company Common Stock"), 
of the Company, other than shares held in treasury or held by Acquiror, TIC or 
any affiliate of Acquiror, will be converted into the right to receive $34.00 
per share in cash. The Company shall be merged with and into Acquiror (the 
"Merger"), and the separate corporate existence of the Company shall cease and 
Acquiror shall continue as the surviving entity. The terms and conditions of 
the Merger are more fully set forth in the Merger Agreement.

You have asked for our opinion as to whether the consideration to be received 
by the shareholders of Company Common Stock pursuant to the Merger Agreement is 
fair from financial point of view to such holders.

For purposes of the opinion set forth herein, we have:

     (i)   reviewed certain publicly available financial statements and other
           information of the Company;

     (ii)  reviewed certain internal financial statements and other financial
           and operating data concerning the Company prepared by the management
           of the Company;

     (iii) analyzed certain financial projections prepared by the management of
           the Company;

     (iv)  discussed the past and current operations and financial condition and
           the prospects of the Company with senior executives of the Company;

     (v)   reviewed the reported prices and trading activity for the Common
           Stock;
<PAGE>   63

     (vi)   compared the financial performance of the Company and the prices and
            trading activity of the Common Stock with that of certain other
            comparable publicly-traded companies and their securities;

     (vii)  reviewed the financial terms, to the extent publicly available, of
            certain comparable acquisition transactions;

     (viii) participated in discussions and negotiations among representatives
            of the Company and Acquiror and their financial and legal advisors;

     (ix)   reviewed the draft Merger Agreement dated ____________, 1999; and
            __________;

     (x)    performed such other analyses as we have deemed appropriate.

We have assumed and relied upon without independent verification the accuracy
and completeness of the information reviewed by us for the purpose of this
opinion. With respect to the financial projections, we have assumed that they

Our opinion is necessarily based on economic, market and other conditions as in
effect on, and the information made available to us as of, the date hereof.

In arriving at our opinion, we were not authorized to solicit, and did not
solicit, interest from any party with respect to the acquisition of the Company
or any of its assets.

Directors of the Company only and may not be used for any other purpose without

consideration to be received by the shareholders of Company Common Stock
pursuant to the Merger Agreement is fair from a financial point of view to such
holders (other than Acquiror and its affiliates).


                                            Very truly yours,

                          IRVINE APARTMENT COMMUNITIES
   Irvine Company Buyout Proposal: Rich Price - No, Reasonable Price - Maybe
                                    (N/IAC)


         December 10, 1998 * Recent Price $31.81 * DJIA 9009 * RMS 305

I. SUMMARY

The Irvine Company (TIC), through a wholly-owned unit, recently proposed to
purchase the 16.6 million shares (83% of the common shares outstanding, or 37%
of the combined common shares and OP units outstanding) of Irvine Apartment
Communities (IAC) that it doesn't already own. The proposed price is $540
million, or $32.50/sh, a 19% premium to the prior day's closing price of $27.38.
TIC is clearly paying a large premium to the value that the public market
ascribed to IAC, but the buyout price does not fully reflect the intrinsic value
of the company and operating partnership as a whole.

TIC's offer is not subject to a financing contingency, and calls for IAC's
existing debt and preferred stock to remain outstanding. TIC announced that it
does not expect the debt or preferred stock to be affected by the transaction.
The offer will be financed from TIC's balance sheet, with the proceeds infused
into IAC as equity, thereby leaving IAC's debt and preferred stock unaffected
from a capital structure standpoint. What is less certain is how the rating
agencies will react as a result of "intangible" changes at IAC. The change in
the financial management team, the possible perception that the new IAC could
lack public market discipline, and the reduction in financing options available
to a private company may be discomforting to the agencies and could result in
negative rating implications. After the announcement of the offer, IAC was put
on credit watch for possible downgrade.

If IAC and the assets of the operating partnership were auctioned off in their
entirety, the company would likely fetch a higher price. However, TIC's majority
control, and the special voting rights that were afforded TIC at the formation
of the company, effectively preclude such an auction from taking place.
Therefore, evaluating the appropriateness of the pricing of the proposal raises
some interesting valuation issues, not the least of which is the disparity in
pricing that the public market ascribed to IAC versus what a private buyer might
pay.

IAC's Board of Directors may determine that the pricing is inadequate, but be
hard pressed to refute the proposal due to the robust premium being offered. At
the end of the day, we believe most shareholders would support the current
offer, but there could be some upside to the price if IAC's Board squawks loud
enough. Of course, squawking too much runs the risk of having TIC revoke its
offer entirely, although that risk is probably remote. In any event, it is hard
to envision a scenario where shareholders aren't at least paid a minimum of
$32.50/sh for their holdings.

The closing date of the transaction is uncertain, but is likely to fall sometime
near the end of the first quarter or early in the second quarter of 1999.
Assuming the company declares and pays a fourth quarter dividend, and the
transaction is completed at the stated price within fourth months, investors
would generate an annualized return of roughly 12% at the current share price.

The proposed buyout is interesting because it sends two messages to the REIT
industry. First, a savvy real estate industry veteran Donald Bren (TIC is
privately held and 100% owned by Mr. Bren), has suggested that the REIT
structure doesn't work for his company. Mr. Bren's conclusion may be alarming
to most REIT proponents, but it shouldn't be because his situation is unique. We
do not foresee a wholesale movement to de-REIT or go private by other REIT
management teams despite such speculation by others. Second, and perhaps more
importantly, Mr. Bren, one of the most successful real estate entrepreneurs in
recent history, determined that the public market valuation of his company was
at least 19% too low. While some may choose to ignore it, the signal being sent
by Mr. Bren should be bullish for REITs in general, and apartment REITs with
exposure to California in particular.

                                   [DIAGRAM]


I.  STRUCTURE

Exhibit 1 contains a chart depicting the structure of IAC and its operating 
partnership. As can be seen, TIC has a sizable (63%) economic interest in the 
operating partnership, directly through its limited partner interest and 
indirectly through its ownership of IAC shares. The bottom line is that public 
shareholders own a minority interest in the operating partnership, although 
they own a majority interest in IAC, the sole general partner of the 
partnership. Despite controlling a majority interest in the general partner, 
public shareholders do not have complete control over the partnership.

The Operating Partnership Agreement, the Certificate of Incorporation, and 
IAC's Bylaws effectively prohibit any sale, merger, or business combination of 
IAC or the operating partnership without the approval of TIC. Thus, IAC is not 
in a position to "auction" off the entire company, and is at a disadvantage 
when it comes to ensuring that the best possible price is paid for its 
interests. This is not to say that TIC's current offer is coercive or even 
unreasonable in any way, but rather that other potential bidders are 
effectively locked out of competing for the company. As a result, TIC is not 
under as much pressure to offer the "best" price possible when proposing to buy 
the company. All other things being equal, TIC has an incentive to pay only the 
minimum price that gets the deal done. We have heard some argue that TIC may 
have aspirations of someday returning to the public market, either with IAC's 
portfolio or the balance of its commercial real estate holdings, and therefore 
is motivated to pay an inflated price to leave public shareholders with a good 
taste in their mouths. While the logic may be sound, $32.50/sh does not 
represent premium pricing for a portfolio and company of IAC's quality.

III.  NAV AND PRICING

In Exhibit 2, we present a range of NAV calculations for IAC as of 9/30/98 
using various capitalization rates. Heretofore, we have used an economic cap 
rate of 7.9% to value IAC's portfolio knowing that other apartment assets in 
IAC's markets have traded hands at much lower cap rates (i.e. higher values). 
We knowingly used an above-market cap rate for two primary reasons. First, the 
7.9% rate, although not reflective of "market", was a full 30 basis points 
lower than that used to value any other apartment REIT portfolio, and REIT 
investors have displayed a discomfort with valuing fringe companies too 
dissimilarly from the average. Second, despite the use of an above-market cap 
rate, we have had a very strong buy on the company for some time, and recently 
touted the company as the

cheapest apartment REIT, and possibly even the cheapest REIT overall. Herein, 
we present a range of economic cap rates from 7.0% to 7.5%. While we present 
three scenarios, our best guess is that the NAV of the company really falls 
somewhere around the mid-range, namely $33.50/sh (rounded). In our calculations 
we attempt to give credit for the current development projects, but ascribe no 
specific value to the Land Rights Agreement between TIC and IAC which gives IAC 
the exclusive right to develop apartments on TIC's extensive land holdings 
through the year 2020.

The value of the agreement is difficult to quantify because TIC is not 
obligated to sell land to IAC, but should it so desire, or be required, to have 
apartments developed, it must sell such land to IAC at a price that is no more 
than 95% of appraised value. Any appraisal based system is subject to abuse 
and/or vagaries, but here the pricing mechanism seemed to work to IAC's 
advantage because the third party "comps" that would presumably be used would 
most likely be inferior properties. Also, if IAC wanted to play hardball, it 
could preclude the development of any new apartments on TIC owned land, and 
effectively "force" favorable pricing in the event that apartments had to be 
developed (zoning authorities often require a minimum amount of affordable 
housing). At the end of the day, it is nearly impossible to accurately estimate 
the value of the agreement, but at the very least it is worth something to TIC 
to buy itself out of the obligation.

At $32.50/sh, TIC's offer is at the lower-end of our estimate of the range of 
IAC's true NAV, and equates to an economic cap rate of 7.4% (a nominal cap rate 
of 7.7%), representing a per unit value of approximately $130,000. The per unit 
value may sound high, but other inferior apartment assets located in Orange 
County have closed during the last few months at valuations of 
$128,000-$148,000 per unit. TIC's offer ascribes no value to terminating the 
Land Rights Agreement nor any "franchise value" for IAC, which has been active 
in creating value through development off the Irvine Ranch in San Diego and 
Northern California. Thus, using an intrinsic value approach, the offer price 
appears to represent a discounted value based on recent private transactions, 
and should provide TIC with meaningful upside.

IV.  CONCLUSION

This transaction is unique in several ways. TIC's majority ownership position 
of the operating partnership effectively gives it control, and diminishes the 
value of IAC's minority interest position. The pricing of REITs of late 
provides an opportunity for TIC to offer a premium to the public market price, 
but a dis-
<PAGE>   67
count to the private market value. The independent committee of IAC's Board 
faces an interesting valuation issue, but should be motivated to maximize the 
value of the offer. James Mead, IAC's CFO, recently announced his resignation 
from the company, and may serve as a good advocate for shareholders; although 
he no longer owns shares himself. Mr. Mead is arguably well suited to assess 
the value of IAC, and doesn't appear to have a bias in determining the 
appropriateness of the current offer.

How IAC's Board ultimately decides to proceed is anybody's guess. TIC's offer 
is not fully-priced based on the public's pro rata share of the value of the 
company as a whole, but it is not a low-ball offer either. At a 19% premium to 
the public market's valuation of the company, TIC's offer is much more richly 
priced than other acquisition or merger transactions that have occurred in 
REITdom, suggesting that the price is more than reasonable on that measure. The 
Board could determine that the offer is acceptable, and have a fairly good 
defense for that conclusion. On the other hand, the Board could determine that 
the offer must reflect IAC's pro rata share of the full value of the company or 
something more close to it. If the Board takes this second stance, there is a 
risk that TIC withdraws its offer and the shares trade back to their previous 
range although we believe that risk is remote. More likely TIC would either up 
its bid, or perhaps call a shareholder vote (which Mr. Bren can do as Chairman 
of the Board) and allow investors to directly evaluate the merits of the 
proposal.

The reality of the situation is that Mr. Bren will be the one to decide whether
a higher price will be paid. IAC's Board can bluster and posture for a fight,
but we think Mr. Bren will ultimately be successful even if the offer is not
increased. His offer is, by any definition, reasonable. However, he has
contended that the offer is actually rich, as a result of his desire to exit the
public market with a feeling of good will from the investment community. We,
however, strongly disagree with his contention that this offer is rich. If he
truly wants to leave investors with a favorable impression, the offer needs to
be increased. The odds of this happening are highly influenced by his own
perception of whether TIC, IAC or some combination thereof may later wish to
access public equity markets again. On this point, we think there is a
reasonable chance of an Irvine-related entity coming public at some point in the
future. Because of this, there is also a reasonable chance that he will choose
to up his offer. We would not suggest that this is a high probability, but we
believe it is a legitimate possibility.

At the recent price, we recommend investors continue to BUY shares of IAC. At a 
minimum, they should provide close to a 12% annualized return and a sweetened 
bid by TIC could enhance that return.

     Irvine Proposes to Go Private. Is This the First of Many? Is the Deal Fair?

                                                                December 6, 1998

     The answer to the first question is maybe some, but not many. There is a
     lot that makes Irvine very different from most other REITs, particularly in
     aspects which affect the probability of going private. Seeing what makes
     Irvine different goes a long way to sorting out the probabilities of others
     following its example. It also provides some insight into the second
     question as to whether this deal is really good and fair for shareholders.
     While it is still early, an affirmative answer on the fairness issue seems
     a stretch.

The Facts

     Late Tuesday, a special purpose affiliate of The Irvine Company proposed to
     purchase all of the outstanding common shares of Irvine Apartment
     Communities, Inc. (IAC: NYSE; hereinafter IAC, or the Company) at a price
     of $32.50 per share, $5.69 or 21.2% over their closing price the prior day,
     and $15.00, or 85.7% over their $17.50 price at their December 1993 IPO.
     The Irvine Company and its affiliates, all largely controlled by Donald
     Bren, owned IAC outright prior to the IPO, and afterwards continued to hold
     an approximate 63% interest in IAC, largely in the form of Operating
     Partnership units. Irvine Company management estimated the compound annual
     return to shareholders since the IPO to a takeover at this price would be
     19.8%, a number which would argue that the take-over was a good deal. But a
     good deal is not necessarily a fair deal; there seem certain other
     alternatives that would address the needs stated by Mr. Bren in a manner
     shareholders might feel better serves their differing interest.

The Differences

     An unusually large number of facts and circumstances make IAC quite
     different from most other REITs and, in almost all these areas of
     difference, make a similar privatization less likely. These include a
     variety of factors reflecting both

                 the feasibility of going-private and incentives unique to The
                 Irvine Company for so doing.

                 FEASIBILITY CONSIDERATIONS: LEVERAGING THE PURCHASE. It seems
                 reasonable to assume that the aggregate purchase price of $540
                 million will be funded by a borrowing against the IAC assets,
                 or at least that would be preferable if it were feasible. The
                 feasibility of arranging this borrowing depends on both not
                 exceeding aggregate loan-to-value ratios at which most lenders
                 would balk and having collateral available to pledge to these
                 lenders. Both these considerations are made relatively more
                 easy by the shares to be purchased being less than a majority
                 of all outstanding shares and OP equivalents, more specifically
                 being 37% of shares and equivalents. Secondly, if the Company
                 is valued at a 9.0% cap rate, then existing liabilities
                 represent 41.3% of value and the $540 million to be borrowed
                 would represent 28.3%; the resulting post-privatization entity
                 would be leveraged at 69.6%, generally a quite feasible
                 level.(1) In an important sense, leveraging for this purchase
                 may be even easier than these ratios indicate because a great
                 deal of the Company's debt is very low cost debt. For the most
                 recent quarter, the Company had a very healthy interest
                 coverage ratio of 5.44 times; if it were to borrow the
                 $540 million at 7.0% - if anything, a slightly lower rate seems
                 feasible -- its coverage ratio would be 2.44 times, still very
                 acceptable to even the most cautious of lenders.

                 The last possible constraint is the availability of
                 unencumbered collateral to pledge to a lender. Based on the
                 Company's 1997 10K, secured indebtedness encumbers only 63% of
                 assets completed at that time, or 55.3% of assets including
                 (and treating as unencumbered) properties then under
                 development.(2) If all properties have uniform per-unit
                 valuations, then borrowing $540 million against unencumbered
                 assets would produce only an 87% loan-to-value on these pledged
                 assets, assuming these assets are valued at a 9.0% cap and
                 assuming no change in G & A, or a 73% LTV at a 8.0% cap with G
                 & A excluded as an operating expense. Including properties
                 under development, the LTV is 63% under the 9.0% cap/100% G&A
                 assumptions, or 53% under the 8.0% cap/0% G&A assumptions.

                 Very simply, even in today's difficult real estate borrowing
                 environment, financing this purchase looks like a no-brainer.

                 FEASIBILITY CONSIDERATIONS: BY-LAW TAKE-OVER IMPEDIMENTS. The
                 Company is a Maryland Corporation. Among the various reasons
                 that the Company, like many other REITs, elected this domicile
                 are the somewhat rigorous and time consuming procedures boards
                 of directors can impose on would-be acquirers to deter a
                 takeover proposal, procedures that are not available in all
                 other states. However, the Company's By-Laws explicitly exempt
                 Mr. Bren and his affiliates from complying with certain of
                 these standards and procedures.

(1) These figures are based on third quarter, 1998 results annualized valuing
property under development and other assets at book and treating G & A as a
property operating expense. Assuming savings of 50% of G & A and an 8.0% cap
rate, gross asset value increases 14% to $2.17 billion, and the resulting
post-privatization leverage reduces to very easy to obtain 61.1%.

(2) This measures assets by rental units. We are told by management that their 
most recent tax exempt financing served to unencumber additional assets.

               INTERESTED STOCKHOLDERS. Maryland General Corporation Law (MGCL) 
               generally prohibits certain "business combinations" between an 
               Interested Stockholder or an affiliate thereof "for five years 
               after the most recent date on which the Interested Stockholder 
               becomes an Interested Stockholder. An Interested Stockholder is 
               defined as any person holding 10% or more of the voting stock. 
               Customarily, after the five-year period, any such combination 
               must be recommended by the vote of the board of directors of the 
               corporation and approved by at least (i) 80% of the votes 
               entitled to be cast by holders of outstanding voting shares and 
               (ii) two-thirds of the votes entitled to be cast by holders of 
               outstanding voting shares of the corporation other than shares 
               held by the Interested Stockholder, unless, among other 
               conditions, the corporation's common stockholders receive a 
               minimum price for their shares and the consideration is received 
               in cash or in the same form as previously paid by the Interested 
               Stockholder for its shares."(3)

               SEC filings by the Company go on to say, "The Articles of 
               Incorporation and resolutions adopted by the Board of Directors 
               have exempted from these provisions any business combination 
               with The Irvine Company, or any affiliates of The Irvine Company 
               or Mr. Bren, or any members of the immediate family of Mr. Bren 
               and any other person acting in concert or as a group with any of 
               the foregoing. All other stockholders are subject to the 
               business combination statute."(4) Effectively, Mr. Bren is 
               excused from having to secure the affirmative vote of two-thirds 
               of the shares in the Company he does not own.

               CONTROL SHARES. MGCL provides that at certain ranges of 
               percentage ownership by a potential acquirer, "control shares" 
               are established that "have no voting rights except to the extent 
               approved by a vote of two-thirds of the votes entitled to be 
               cast on the matter, excluding shares of stock owned by the 
               acquirer or by officers or directors who are employees of the 
               corporation." With his ownership of common shares currently at 
               17%, Mr. Bren does not have the minimum one-fifth common-share 
               ownership percentage that would normally trigger the "control 
               share" rule. But again, as reported in Company's SEC filings, 
               "the Company's bylaws adopted by the Board of Directors have 
               exempted control share acquisitions involving The Irvine 
               Company, or any affiliate of The Irvine Company or Mr. Bren, or 
               any members of the immediate family of Mr. Bren and any other 
               person acting in concert or as a group. All other stockholders 
               are subject to the control share acquisition statute." Mr. Bren, 
               unfettered by the control share statute, is now free to convert 
               enough of his interest in the Operating Partnership into common 
               shares (under the Exchange Rights granted to The Irvine Company) 
               to achieve the requisite voting control of the Company, and then 
               would not have these holdings subject to the Control Shares 
               provisions and restrictions as specified in the Company's 
               Articles of Incorporation.

          These provisions make Mr. Bren different from other would-be 
          acquirers of the Company.(5) In the event his buy-out proposal is 
          contested then, Mr. Bren

(5) Another item in the bylaws which is not especially unique but deserves some 
small mention here because it could potentially have had a role in deterring a 
contested takeover of the Company. The Company's bylaws require that "with 
respect to an annual meeting of stockholders, the proposal of business to be 
considered by stockholders... may be made only by advance written notice 
procedures set forth in the Bylaws." The advance notice procedures also apply 
to the nomination of persons for election to the Board. However, Company 
filings make clear Mr. Bren's considerable advantages. "The advance notice 
provisions are not applicable to The Irvine Company," which suggests that 
competing offers to purchase the Company could potentially never be included in 
Board business or presented at a shareholders' meeting.

          would not have to jump through various requirements that might be an
          annoyance, if not a final deterrent, to others interested in taking
          over the Company. While we have not made a similar survey of the
          by-law provisions of other REITs, we strongly suspect that few give
          similar privileges to their dominant shareholder.

          FEASIBILITY CONSIDERATIONS: DEBT COVENANTS. There seems to be a good
          chance that leveraging up might violate certain loan covenants,
          especially leveraging up with secured debt. The Company's shelf
          registration statement speaks of covenants not to permit debt to rise
          above policy limits of 60%. Setting aside the problem of determining
          how a private Company might determine debt to market cap ratios, it is
          probably more relevant to consider what would be the consequences of a
          violation of loan covenants. In most cases, the recourse of debt
          holders is to call their loan, not to reset or establish any kind of
          penalty interest rate. A decade ago, in the midst of a collapsing real
          estate market, more than one lender who called a loan after a
          technical default only to find the borrower appearing the next day
          tendering repayment at a 100 cents on the dollar, having happily
          avoided loan-maintenance prepayment penalties in repaying an expensive
          loan. While IAC might not experience as large a windfall, there does
          seem some possibility it might easily refinance existing indebtedness
          at a lesser cost. The Company's existing $100 million of unsecured
          notes, its liability most likely to contain covenants which would be
          violated, bears interest at 7.0%, slightly higher than where it could
          likely refinance this debt.

          FEASIBILITY CONSIDERATIONS: DE-REITING AND OTHER TAX ISSUES. There are
          likely a great many tax issues that complicate a takeover or
          privatization, including the possibility that IAC could lose its REIT
          tax-status, and/or that the IAC Operating Partnership might terminate
          for tax purposes. In considering these topics we are swimming in
          dangerous waters where tax-sharks more knowledgeable than we have
          previously taken big bites of our flesh. However, to our amateur eye,
          there seem to be important differences in the details that make a
          privatization easier for Mr. Bren than it would be for other major
          holders of other REITs.

          De-REITing seems an inevitability for Mr. Bren and for many other
          would-be acquirers of other REITs. De-REITing means that the tax-free
          pass-through of cash flow would be lost; instead, any cash flow passed
          through what was the IAC REIT would now be diluted by taxation. While
          tax-free pass-through could be regained by exchanging the REIT shares
          for OP Units, such an exchange seems unlikely to be deemed a
          like-kind, and therefor tax-deferred exchange. Tax deferral should
          make no difference for Mr. Bren because his basis in newly-acquired
          REIT shares would be $32.50, meaning that the taxable gain and tax
          liability would be minimal to non-existent.(6) So far, there is
          nothing in Mr. Bren's position that makes him different from dominant
          shareholders of other REITs.


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

(6) There would be gain only if the value of OP Units were deemed to be greater
than the $32.50 per share basis. Mr. Bren might, however, have a tax liability
with respect to shares owned by him to the extent that these shares had a lower
basis. A minority, but significant part of his holdings are in the form of
shares.

<PAGE>   72
     This moves to the second problem, where the facts and circumstances of the
     Company vary significantly from other REITs. Assuming that the transaction
     by which REIT shares are replaced by OP units is deemed for tax purposes a
     transfer of OP Units, then, if 50% or more of the interests in the
     Operating Partnership were so transferred, the Operating Partnership might
     terminate for tax purposes, giving all former OP unit holders a taxable
     gain to the extent of difference between the fair market value of their OP
     units and their tax basis in these units. But in fact, the Irvine Company
     holds an approximate 55% interest in Irvine Apartment Communities, L.P.,
     the Operating Partnership, of which IAC is 45% general partner. Thus a
     transfer of all of the OP units of IAC would not create a tax termination
     of the Irvine Apartment Operating Partnership. In this respect, IAC is very
     different from most other REITs. There may be other ways others could skin
     their respective cats, but these methods seem unavailable at most other
     REITs.

     Very simply, the facts and circumstances unique to Mr. Bren and IAC seem to
     suggest that tax issues and potential costs that others might face are
     absent here.

     SPECIAL INCENTIVES: LAND ISSUES. IAC had now come face to face, but not yet
     come to grips with a zero-sum issue that would pit the interests of public
     shareholders against controlling insiders. The issue is, of course, the
     pricing of land to be purchased by IAC from Mr. Bren's Irvine Company, on
     which IAC would develop additional apartment communities. At the IPO, under
     what is known as The Land Rights Agreement, The Irvine Company agreed to
     sell land to the Company for an interim period at prices which were
     estimated to result in a total 10.0% to 10.5% return on the Company's total
     investment. The Company's rights to buy under this arrangement lapsed with
     the land previously purchased on which 1,884 apartments have been or are
     now being constructed. Thereafter, purchase prices were simply not to
     exceed 95% of appraised value.

     Given history and the interests of parties concerned, value seems like a
     fight waiting to happen, and, but for this privatization, likely to have
     happen very soon. Mr. Bren and the Irvine Company would point to the same
     thing they pointed to in announcing the buy-out proposal: "Accretive
     acquisitions of Class A multi-family properties in California are difficult
     to find." This means that cap rates are low and land should be priced to
     reflect a similar low rate of return on investment. In fact, we think it
     likely that they might argue that land on the Irvine Ranch should be priced
     at an even lower cap and return on cost than land elsewhere. Other parties,
     however, might point to the land for the 1,884 units bought most recently.
     Absent some prior agreement that these transactions could not be deemed a
     comparable, it could be argued that these are the most direct comparable,
     even if slightly stale.

The difference, we strongly suspect, is quite large, perhaps 300 to 400 basis 
points of return on total investment. A difference of 300 basis points could 
amount to something like $60,000 per rental unit(7). Mr. Bren then faced the 
pos-

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

(7) The figure of $60,000 is based on a pro forma valuation of the Company at
    $127,000 per unit based on a 9.0% cap rate, and otherwise on the assumptions
    more fully described above. If, alternatively, value were premised on a 6.0%
    cap rate on the same average per unit NOI, per unit value would be $190,500
    per unit or $63,500 per unit higher. This is an imperfect comparison in that
    we are comparing implicit per unit valuation as between 9.0% and 6.0%, as
    compared to a more likely range of dispute of between 10.0% and 7.0%; but it

     sibility that if he ultimately won the value war, it would destroy the
     economics of IAC which he owns a majority of, while at the same time
     alienating all other holders of IAC shares(8). There is also the
     possibility that he might have been advised that he wouldn't win the
     valuation argument or that if he won in the short run, he could expect to
     subject to all sorts of shareholder rights suits, some of which might seek
     punitive damages. The fight was going to have costs, even if it was
     ultimately won. There seems to be value simply in avoiding the fight as is
     achieved by taking the Company private.(9)

     SPECIAL INCENTIVES: COMFORT AS A PUBLIC COMPANY. Donald Bren's role at IAC
     had very few, if any, parallels in the REIT industry. He has a stature as
     an experienced and successful investor over a number of years, a reputation
     similar to that held by Sam Zell, Mort Zuckerman, or Richard Rainwater. But
     he did not choose to take a particularly visible role and rarely attended
     industry functions or in other ways tried to extend the luster of his
     reputation in any which might expand the pricing multiple of IAC shares.
     But although his face was rarely seen, his hand was more visible. We saw
     what appeared as his influence in the turnover of senior officers,
     especially officers who seemed to develop an independent standing or
     stature in the industry.

     First was Dick Moran, who was nominally Executive Vice President and CFO at
     the IPO but held the position of highest visibility initially. In March
     1995, the nominal President as of the IPO, T. Patrick Smith, was gone and
     Mr. Bren stepped in as Acting President. Many people, ourselves included,
     expected Moran to be named President, thus formally acknowledging the role
     he seemed already to have. In May 1995, Steven Albert joined IAC to become
     President; in October 1996 Moran announced his departure and shortly
     thereafter emerged as CFO at Kilroy Realty Corp. Moran was replaced as CFO
     by Jim Mead who been at IAC in a less visible position for some time. Mead
     then assumed a profile very similar to what Moran had held. By the time
     IAC's 1996 Annual Report was released, Albert was no longer President and
     Mr. Bren was once again, this time with no hyphenated "Acting" preceding
     that title.

     But that tenure was short-lived, and in 1997, William McFarland, who had
     become a director in 1996 and had been associated with Irvine affiliates
     since 1984 and with Mr. Bren previously, became President. Then, in October
     1998, the departure of Jim Mead was announced, as of early 1999.

     Admittedly, what we draw from these patterns is subjective, not conclusive
     and subject to different interpretations. But what we see is a pattern of
     those who have developed an eyeball-to-eyeball sense of trust with the
     investing public not lasting long, while Mr. Bren seems to work his will
     while avoiding the development of any relationship with other shareholders.
     By no means does this suggest that Mr. Bren has or is about to willfully do
     anything to harm the interests of public shareholders. Rather, it suggests
     that he may not have

- --------------------------------------------------------------------------------
     does nevertheless give some sense of the magnitude of the gap. At $60,000
     per apartment unit, the $540 million purchase price would be fully recouped
     with 9,000 units, roughly 52% of what the Company now has.

(8)  Based on this possibility, an argument could be made that Mr. Bren is doing
     shareholders a favor by buying them out now rather than later.

(9)  On the other hand, if the argument that the 10.0% to 10.5% return is real
     value was to win, there might also be a strong argument that the $32.50 per
     share buyout price is inadequate.

IRVINE GOES PRIVATE                   DECEMBER 6, 1998                    PAGE 6

                 developed a sense of being partners with shareholders to the
                 same extent as other, more visible REIT major-domos. In taking
                 IAC private, there is clearly no sense that, for better or
                 worse, we are all in this together.

IS THIS GOOD DEAL
     A FAIR DEAL?

                 At the advertised 19.8% compound annual return, it seems that
                 investors have a deal that should elicit few complaints. A
                 19.8% return is considerably better than the NAREIT Equity
                 Total Return Index which produced an IRR we measure at a little
                 over 10% over that same period.(10) But on the other hand,
                 these have been times of strong cyclical recovery. And in
                 California that recovery lagged the rest of the country,
                 meaning that compared to REITs with assets elsewhere, a larger
                 part of the California recovery occurred during this period,
                 and a lesser portion at times preceding this. Thus a 19.8%
                 return could well be merely what is to have been expected from
                 California assets over this time, or maybe even less than what
                 should be expected.

                 No less important, a good return is not necessarily the same
                 thing as a fair return. There will be those who assume that
                 anytime an insider buys from outsiders, the outsiders are being
                 disadvantaged, that the buyer, who can be presumed to know
                 relevant facts than the seller, thinks there is value at the
                 price being paid. Going from raw paranoia to the numbers seems
                 to dissipate the case, but only very slightly.

                 PER UNIT VALUATIONS. At $32.50 per share, the valuation of the
                 Company is roughly $148,000 per apartment unit.(11) This
                 compares to roughly $153,000 per unit cost of recently
                 constructed or now under construction units on the Ranch (which
                 were built on land priced to yield a 10.0% return), or $211,000
                 off the Ranch.(12) Off the Ranch figures are skewed by a
                 119-unit development in Santa Monica, estimated to cost
                 $630,000 per unit, but then again, that Santa Monica asset is
                 included in what Mr. Bren proposes to soon own all of at a
                 valuation of $148,000 per unit.

                 CAP RATE VALUATIONS. Based on trailing NOI, the value seems to
                 imply a 6.8% cap rate.(13) There would be roughly 20 basis
                 points of incremental yield from halving G&A. Adding in the
                 development pipeline at a 10.0% yield, together with halving
                 G&A gives an indicated 8.16% yield. If the development pipeline
                 produces a yield 50 basis points higher (i.e. 10.5%), the
                 composite cap rate moves by a little over 10 basis points to
                 8.27%. And lastly, if forward-looking, rather

(10) We have calculated return on the NAREIT Index using an internal rate of
return over the same time frame.

(11) These calculations reflect (a) the sum of (1) 45.09 million shares and
equivalents times $32.50 each, plus (2) $789 million of liabilities, plus (3)
$144 million of redeemable preferred shares, plus (4) an estimated $333 million
to complete properties now under construction, less (5) $41 million of other
assets, divided by (b) 18,197 units. The figure of 18,197 units includes units
presently under construction. This data is drawn from Company reports as of the
end of its third quarter, 1998.

(12) It might be argued that newer units should have a value above existing
older units. But IAC's old units bring with them one almost unique difference
which positively influences their value: roughly $325 million of tax-exempt
mortgage bond financing bearing interest at a rate of 5.28%. Indeed, as of the
end of 1997, IAC's $704 million of debt bore interest at a weighted average rate
of 6.06%.

(13) This figure is based on $36.6 million of quarterly NOI, annualized to
$150.5 million divided by the value determined for per units calculations above.


                 IRVINE GOES PRIVATE         DECEMBER 6, 1998             PAGE 7
<PAGE>   75
     than trailing NOI were used, as is customary, there might be 10 to 30 basis
     points additional increase in return, especially given the strong movement
     in rents in this market.

     It would be interesting to compare these per unit and cap rate valuation
     benchmarks with the specific examples that brought The Irvine Company to
     conclude that "Accretive acquisitions of Class A multi-family properties in
     California are difficult to find." It looks like Mr. Bren may have found a
     quite accretive acquisition sitting right under his nose.

     MORE EQUITABLE ALTERNATIVES. The leverage feasibility analysis above seems
     to argue that, in full fairness, shareholders perhaps should be offered one
     or two other alternatives to a buyout. The first alternative would be to
     keep ownership as is, take down similar debt and distribute the proceeds to
     shareholders. That would of course mean the $540 million would go to all
     shareholders and thus be less than $32.50 per-share; we estimate it would
     be roughly $11.98 per-share. And it would have a negative impact on per
     share FFO which can be estimated at a reduction of roughly $0.84 per year.

     While many shareholders might find this a not altogether attractive
     alternative, in a roundabout way, thinking about this possibility brings up
     another potential solution to the problems that seem to have brought Mr.
     Bren to propose a buyout as being in the best interests of the Company.(14)
     Part of the stated reason for going private is to be able to retain
     capital. Buy by leveraging up to fund a privatization, there is actually
     going to be less cash flow available, even if all of it could be retained
     and reinvested. Despite this inconsistency with Mr. Bren's stated goals,
     the transaction is attractive to him, largely because of a presumed cost of
     the capital necessary to effectuate the buyout of 7.0% or less. Thus it
     might more in the interest of shareholders to leave ownership unchanged,
     but increase its leverage to extent of $540,000 million and invest those
     proceeds in the opportunities Mr. Bren sees as being lost to the present
     obligation to distribute all cash flow; then shareholders in addition to
     Mr. Bren might enjoy the benefits of higher leverage at prevailing rates.
     Or stated another way, there is more than one way to deal with the problems
     Mr. Bren purports to be solving and many shareholders might find that
     solution preferable to being bought out at $32.50 per share.

PROBABILITIES
ELSEWHERE

     Very few other REITs seem to have similar facts and circumstances to make a
     take-over by dominant insiders likely. In our coverage universe, REITs
     where insiders hold a large percentage of effective ownership of the
     consolidated enterprise include Boston Properties (19.4% owned by the
     chairman, management and their families), Cousins (19.2%), Crescent
     (13.0%), CBL (27.9%), General Growth (17.2%), Simon (23.6%, including
     DeBartolo family interests), Urban (38.0%), and Taubman (17.7%).(15) All of
     these are some distance from the

      wholly separate from the interests of its various shareholders. It seems 
      to us a more constructive approach would be to view the interests of the
      Company as equivalent to the aggregate interest of these owners.

(15)  This is calculated based on shareholdings of the chairman and board as of
      their most recent proxy and shares and equivalents as of the third quarter
      of 1998.

     level owned by Mr. Bren. Existing debt as a percentage of the fair market
     value of assets, using a 9.0% cap rate on trailing NOI annualized, is
     generally higher than IAC's level. At Boston Properties, liabilities equal
     52% of FMV calculated on this method, at Cousins 31%, at Crescent 42%, at
     CBL 66%, at General Growth 78%, at Simon 94%, at Taubman 58% and at Urban
     70%. Using an 8.0% cap rate, the mall REIT's leverage is lower, 59% for
     CBL, 70% for General Growth, 83% for Simon, 52% for Taubman, and 62% for
     Urban. Very simply, the likelihood of the dominant shareholders of these
     REITs following Mr. Bren's example seem quite low. The most plausible
     exception seems to be Cousins, where there may also be hidden value in
     non-income producing land holdings.

     In a sense, this analysis seems to turn the convention wisdom that larger
     ownership interests by management are better than smaller. But as we see it
     the correct conclusion is more a refinement than a refutation of
     conventional wisdom. In effect a corollary should be added to conventional
     wisdom: when management's interest is so large as to give them effective
     unilateral control, it is good to be attentive to all those signals which
     indicate whether such a dominant shareholder views other shareholders as
     either his partners, or as a convenient source of the interim financing for
     his company.

TYING THIS DEAL TO
OUR MACRO
PERSPECTIVES STATED
ELSEWHERE

     Our regular readers are no doubt aware of our recent speculations regarding
     the possibility of deflation in real estate.(16) In those ruminations, we
     have argued that certain types of property might be spared the negative
     effects of deflation and instead experience land appreciation to arrive at
     a full equilibrium between, on one hand, supply and demand as reflected in
     rents and, on the other hand, replacement cost as factored by the cost of
     capital, the long-term debt portion of which has recently declined
     significantly and appears likely to remain low. We argued that the more
     favorable scenario is more likely in circumstances where the providers of
     space have some pricing control, some ability to avoid the other scenario
     characterized by real declines in rents rather than land appreciation.
     While we have also characterized urban properties as more likely to perform
     in a manner consistent with the land appreciation scenario, not all urban
     areas would enjoy this pattern and not all non-urban would not. One of the
     more likely locations to perform well is the Irvine Ranch, a prospect that
     argues that it, or more specifically, the Company should be valued
     differently than real estate in other locations. It also means that IAC
     might be especially missed by investors and those of us who like to try to
     figure out what is really going on.

           Market Analysis of REITs & Real Estate Operating Companies

WATERSHED OR NO BIGGIE?

     After the market closed on December 1, The Irvine Company, a private real 
estate entity controlled by Donald Bren, announced an offer to buy the 
approximately 16.6 million shares of Irvine Apartment Communities that it 
doesn't already own for $32.50 per share. Simply put, in a deal valued at $540 
million, Bren is proposing to take private the company that he took public in 
December 1993 at $17.50 per share. The Irvine Company hopes to have the deal 
approved by the end of this year.

     The Irvine Company is the largest current stockholder of IAC. As of 
December 1, it held approximately 17% of the outstanding common shares. It also 
owns approximately 55% of the partnership interests of Irvine Apartment 
Communities, L.P. of which IAC is a 45% general partner. In all, Bren owns an 
approximate 63% economic interest in IAC. Bottom line: After roughly five years 
in the public fishbowl, Bren has apparently decided that he wants it all!

     In its press release announcing the proposal, The Irvine Company stated 
that the bid is not subject to a financing contingency. In addition, The Irvine 
Company noted that the existing debt and preferred stock of Irvine Apartment 
Communities, L.P., IAC's operating partnership, will remain outstanding and are 
not expected to be affected by the proposed transaction.

     We have mixed feelings about Bren's offer. On one hand, Bren is paying a 
"fair" price for IAC (more on that subject, in a bit). On the other hand, 
though IAC has had its ups and downs -- a mind-boggling number of senior level
management changes hasn't helped matters -- it is the sort of company we'd like
to see in the public arena. Furthermore, it has delivered solid returns for 
investors, and our view is that even "better times" lie ahead.

BIG QUESTIONS

     Is Bren the first of many to pack it in and take his REIT private? We 
don't think so. First, we never thought Bren's heart was really in being 
public. (He shuns the spotlight.) His attitude toward the public market from 
the outset was tentative, at best. We 
<PAGE>   79
suspect Bren took IAC public -- and thought long and hard about taking other
pieces of The Irvine Company public -- not because he, like a Sam Zell, saw the
"equitization" of real estate as a long-term goal, but rather because it solved
shorter-term issues. (Though we suspect that had things gone differently he
might have stayed around, at least a while longer.) So, as we see it, Bren's
decision doesn't say anything about the resolve of those who came public over
the past five years or so to remain public.

     Second, though some observers suggest the price Bren is offering -- roughly
a 20% premium to what IAC was going for before the announcement -- confirms that
REITs are under-valued by the market currently, we don't agree. REITs may be
cheap on a relative and possibly even on an absolute basis, but whatever price
Bren has to pay to get the shares of IAC he doesn't already own, it reflects the
uniqueness of the situation. Extrapolating from what Bren is willing to pay to
the market generally isn't warranted, though it would be nice to be able to do
so.

IAC RECAP

     According to IAC's latest 10-Q (filed on November 11), the company had
20,129,873 common shares outstanding as of October 31. It owned 62 apartment
communities (it owned 42 when it came public) with 16,029 apartment units. (The
overwhelming majority of those are located in Orange County, California on the
Irvine Ranch.) It had 2,729 apartment units under development. The company broke
ground on its first apartment community, off the Irvine Ranch in Northern
California's Silicon Valley, in May of last year.

     IAC reported third quarter FFO/share (diluted) of 60 cents vs. 51 cents in
the year-ago period. (It's 3Q98 FFO/share was a penny or two ahead of most
estimates, by the way.) FAD (funds available for distribution) was 57 cents vs.
49 cents in the year-ago period. (Weighted average shares/units outstanding was
45.157 million.) Same-store results -- 48 properties with 13,451 units owned and
stabilized before 1997 -- experienced a 10.1% increase in net operating income
over the year-ago period ($32.5 million vs. $29.5 million). Average monthly rent
went from $1,119 to $1,171 per unit. Physical occupancy went from 93.8% to
94.1%.

ISSUES TO WEIGH

     Bren isn't trying to steal the company, but he's not overpaying either. His
offer of $32.50 per share is, as noted, well above the price IAC was changing
hands at immediately prior to the announcement. It's also a premium over "our
consensus NAV of $24.43 per share." (The high end of the consensus is in the
neighborhood of $28 to $29 per share.) However, recent conversations with
non-REIT folks in Orange County who are familiar with IAC's portfolio and local
economics lead us to believe that in some instances the cap rates being used to
value the portfolio are on the high side. (Something in the low 7% range seems
right to us.) More important, however, when IAC came public there was a good
deal of controversy about its valuation, generally, and specifically about the
company's unique development story. So, though an investor who bought IAC at the
IPO and held on to it has done well, we believe Bren's offer doesn't fully
reflect the "future" value that shareholders paid for when they bought IAC. It's
tough to nail down a hard number, though if IAC develops, say, $150 to $200
million in apartments per year and earns a 20% to 25% development profit on that
investment, it would add at least another $30 million to the mix annually. An
offer in the $34 to $35 range better reflects not only IAC's current value, but
also gives investors who bought the development story's potential something for
their vote of confidence in Bren.

     It will be interesting (no, fascinating) to see how IAC's senior executives
and independent directors deal with Bren's offer. As one buy-sider put it, "Bren
casts a mighty large shadow, especially in Southern California." (This is yet
another test of corporate governance in the REIT sector.) Again, we wouldn't
accuse Bren of trying to steal the company, but given what he said when IAC came
public about the development story, we'd feel a lot better if he sweetened his
offer by $1.50 to $2.50 a share.

     When we went to press, IAC was changing hands at $31? per share. Assuming a
transaction at $32.50 per share -- and counting IAC's fourth quarter dividend of
38.5 cents per share -- an investor could earn roughly a 4% total return in a
month. Not too shabby! Moreover, in our view, there's at least a 50/50 chance
that Bren will sweeten his offer. For those reasons, we're raising our rating on
IAC from DCA to a BUY.

HIGHLIGHTS          o  On December 2, The Irvine Company, a privately held real estate concern controlled by Donald
                       Bren, announced a proposal to acquire the 16.6 million common shares of Irvine Apartment
                       Communities (IAC) that it does not already own for $32.50 per share in cash--a 21% premium to the
                       most recent closing price. On the quantitative front, the pricing of the transaction appears rich
                       in light of declining property values, therefore presenting a clear positive for current
                       shareholders.

                    o  The proposed takeout price is set at 12.5 times our revised 1999 FFO estimate and approximately 
                       12.5 times our estimated EBITDA (after stripping out approximately $200 million in land and
                       construction in progress), or about an 8% cap rate equivalent--a 30%-plus premium to its peer
                       group multiple. On the qualitative front, we are also surprised that The Irvine Company is taking
                       IAC out of the public fold and willing to forego access to both public and private capital.

                    o  With respect to our earnings estimates, we are revising our estimates for 1998 and 1999. For 1998
                       we are raising our FFO estimate from $2.20 per share to $2.30 per share and our FAD estimate from
                       $2.07 per share to $2.16 per share. In 1999, we are raising our FFO estimate from $2.50 per share
                       to $2.60 per share and our FAD estimate from $2.29 per share $2.40 per share.

                    o  In our view this is not the beginning of a wave of REIT LBOs.

                    IRVINE APARTMENT COMMUNITIES ACT (IAC)
                    RATING: MARKET PERFORMANCE
                    ------------------------------------------------------------

VIEWPOINT           On December 2, The Irvine Company, a privately held real 
                    estate concern controlled by Donald Bren, announced a 
                    proposal to acquire the 16.6 million common shares of 
                    Irvine Apartment Communities (IAC) that it does not already 
                    own for $32.50 per share in cash -- a 21% premium to the 
                    closing price. This transaction essentially amounts to a 
                    leveraged buyout (LBO) and would take IAC private. Recall, 
                    IAC has been somewhat of a financing entity in that it has 
                    acted as a vehicle to develop certain land interests on The 
                    Irvine Ranch in California held by Donald Bren. It is 
                    notable that the takeout price implies a total enterprise 
                    value for IAC of $2.20 billion, of which $736 million is 
                    debt. Of the $1.46 billion in equity, The Irvine Company 
                    holds the $813 million of operating partnership units
                    (OP units) an additional $111 million in common stock, 
                    thus making the tender offer for $540 million. The offer is 
                    not subject to financing contingencies.

                    In our view, we find this transaction surprising on both 
                    quantitative and qualitative fronts. On the quantitative 
                    front, the pricing of the transaction appears rich in light 
                    of declining property values, therefore presenting a clear 
                    positive for current shareholders. We have expressed for 
                    some time our opinion that asset values are likely to be on 
                    the decline due to the stanching of both debt and equity 
                    capital for real estate. Furthermore, while we have always 
                    recognized IAC's quality asset base and strong market 
                    fundamentals, our neutral rating on the stock has been 
                    purely a function of its 12% comparative multiple premium. 
                    The proposed takeout price is set at 12.5 times our revised 
                    1999 FFO estimate and approximately 12.5 times our 
                    estimated EBITDA (after stripping out approximately $200 
                    million in land and construction in progress), or about an 
                    8% cap rate equivalent -- a 30%-plus premium to its peer 
                    group multiple. Without knowing for sure, Mr. Bren is 
                    obviously paying this premium for IAC shares based on his 
                    more bullish view of the company's upcoming development 
                    pipeline, asset values, and future growth prospects. On the 
                    qualitative front, we are also surprised that The Irvine 
                    Company is taking IAC out of the public fold and is willing 
                    to forego access to both public and private capital. Mr. 
                    Bren obviously believes -- maybe rightfully so -- that 
                    retention of cash flow as a private company and lack of 
                    public scrutiny will provide it greater flexibility as a 
                    developer; he may also believe accounting issues relating 
                    to development are unduly restraining.

                    With respect to our earnings estimates, we are revising our
                    estimates for 1998 and 1999. For 1998 we are raising our FFO
                    estimate from $2.20 per share to $2.30 per share and our FAD
                    estimate from $2.07 per share to $2.16 per share. In 1999,
                    we are raising our FFO estimate from $2.50 per share to
                    $2.60 per share and our FAD estimate from $2.29 per share
                    $2.40 per share. Given today's news and the move in the
                    stock, it is now clear IAC shareholders have maximized
                    value.

IMPORTANT POINTS    Is this the first in a wave of REIT LBOs? In our view, it 
                    is not. We think the IAC transaction is an anomaly for 
                    several reasons. First, the acquirer in the IAC transaction 
                    already owns 67% of the enterprise. Therefore, the cross 
                    ownership of the two enterprises makes this deal somewhat 
                    unique. Donald Bren, most likely, believes that retention 
                    of capital would provide The Irvine Company an important 
                    source of funds with which to finance its large development 
                    appetite. Second, Mr. Bren has historically shunned the 
                    public markets, and most likely views private ownership of 
                    IAC to be less restrictive. Third, we estimate that most 
                    REITs trade only on par with their underlying net asset 
                    values. At these levels, prices are too high to undertake 
                    LBOs.

     IAC's core market, Orange County, should continue to perform well over the
     near-to-intermediate term. In our recently rolled out DLJ Real Estate
     Forward Supply/Demand Index, we highlighted the 20 markets that contain the
     most and least supply versus demand risk over the next 18 months. Based on
     our calculations, we contend that Orange County should exhibit greater
     demand growth than supply growth (by about 200 basis points). The Irvine
     Company may now be willing to pay the premium it has offered because of its
     current and expected strength in this core market of theirs.

     Does this transaction change the competitive landscape in the Southern
     California apartment market? Given the fact that we consider Donald Bren
     and his organization to be "smart money," this transaction is a very
     bullish signal that there is imbedded value in the Southern California
     apartment markets. However, we do not think the competitive landscape
     between IAC and its competitors should change much. We say this because IAC
     will likely continue in its private form developing, acquiring, and
     managing its operations at least as aggressively as it has been in the REIT
     wrapper. Thus, today's transaction is a bullish signal from a well-heeled
     investor about the prospects for other multifamily REITs situated in
     southern California, such as Archstone Communities (ASN), AvalonBay
     Communities (AVB), Essex Property Trust (ESS), and Pacific Gulf Properties
     (PAG). BRE Properties (BRE) and Equity Residential (EQR) could also benefit
     if Mr. Bren's confidence in his real estate markets manifests.

KEY POINTS
- -We have downgraded our rating on Irvine to Neutral from Outperform.

- -Irvine Apartment Communities' stock price rose 15% to $31 9/16 from $27 3/8 on 
Wednesday December 2, 1998 after the announcement that the privately held Irvine
Company offered $32.50 for the 16.6 million shares outstanding that it does not 
own.

DETAILS

*WE ARE DOWNGRADING OUR RATING TO NEUTRAL FROM OUTPERFORM. The board of Irvine 
Apartment Communities (IAC) received a letter from TIC Acquisition LLC, a 
subsidiary of The Irvine Company (TIC) proposing to acquire the outstanding 
shares in the REIT for $32.50 per share. The stock closed yesterday at $31 
9/16, which is within 3.0% of the offered price. The shares traded up 15% from 
the prior day's close of $27 3/8. TIC management indicated they would like to 
close during the first quarter of 1999. We think a competing bid is unlikely. 
The price would have to move beyond $36 to warrant an Outperform rating. 
Consequently, we have downgraded our rating to Neutral.

*THE IRVINE COMPANY OWNS A MAJORITY OF THE OPERATING PARTNERSHIP. The Irvine 
Company is a privately held real estate firm that owns the Irvine Ranch in 
Orange County, California. The ranch is the largest master-planned community in 
the country. TIC owns 55% of the partnership interests of Irvine Apartment 
Communities, L.P. Irvine Apartment Communities, the REIT, owns the remaining 
45%. However, TIC also owns 17% of the stock in the REIT, giving TIC an overall 
63% economic interest in the operating partnership.

- --------------------------------------------------------------------------------
*A SUBSIDIARY OF THE IRVINE COMPANY MADE THE $32.50 PER SHARE PROPOSAL. The
proposal was made on December 1, 1998 to the Board of Directors of IAC with a
response requested by December 31, 1998. Now, we believe the board has to have
its committee evaluate the proposal and provide an answer.

*WE DO NOT EXPECT COMPETING OFFERS. One of the attractions of investment in IAC
was its exclusive right to develop multifamily communities on the Irvine Ranch.
Management of TIC indicated to us that such a right might not transfer to
another acquirer of the REIT, which could make such an investment much less
appealing. Also, the $32.50 per share price offered represents 12.7x our 1999
FFO estimate of $2.55 per share. Such a price would likely be dilutive to most
other REITs.

We had been carrying a $31 per share net asset value (NAV) for IAC. Thus, a
price of $32.50 appears reasonable. We derived our net asset value using an 8.0%
cap rate on fourth quarter expected net operating income. We calculate that it
would take a 7.75% cap rate to reach the $32.50 per share level. In addition, a
price-to-FFO multiple of 12.7x our 1999 estimate, or 13.7x using our AFFO
(adjusted FFO, or FFO less recurring capital expenditures) estimate is well
beyond the upper end of the range we are carrying for our multifamily universe.
TIC management indicated that the offered price represented a 21% premium to the
stock's closing price prior the offer.

*TIMING IS STILL UNCERTAIN. Management of TIC indicates it would likely pursue a
merger with the REIT or a tender offer. A merger could take much longer owing to
requirements for the mailing of a proxy, setting a shareholder meeting, and
conducting the vote. A tender offer, however, could proceed much more quickly if
the requisite number of stockholders tender their shares.

*TIC HAS FINANCING LINED UP. TIC delivered a no financing contingency offer to
IAC's board. The funds are immediately available to close on the transaction.
TIC has a $350 million acquisition term loan from the Bank of America and other
cash and credit facilities available to fund the $540 million needed to purchase
16.6 million shares at $32.50. If successful, TIC would leave the operating
partnership intact and, therefore, would not have to retire its outstanding debt
or preferred stock.

*TIC OUTLINED SEVERAL REASONS FOR THE TRANSACTION. Among them, it believes it
can access capital on a more cost efficient basis as a private company. Raising
equity has become a more expensive proposition for REITs, including IAC, at
current prices. Also, the dividend distribution requirement limits the amount of
capital left to reinvest in the business and fund development.

For a more detailed discussion on how this may affect other multifamily REITs,
see our First Call note dated December 2, 1998.

Real Estate (I/REA): IAC COULD BE FIRST MULTIFAMILY REIT TO GO PRIVATE
Steven G. Bloom, CFA (212) 761- 6284                  
                                                      Date: December 2, 1998
                                                      Type: Industry Overview

KEY POINTS

- - The Irvine Company plans to take Irvine Apartment Communities, a multifamily
REIT, private at $32.50 per share. The decision to go private points to some
REIT limitations like the inability to retain and the high current cost of
raising capital.

- - In most ways, the situation is unique to this REIT. However, it does confirm
our belief that many multifamily REITs are trading at or below net asset value
(NAV).

- - In our universe, Berkshire Realty (BRI, $10, Outperform) and Summit Properties
(SMT, $17, Outperform) are trading about 20% below our estimated NAV.

- - We think the better-managed companies with exposure to strong markets ought to
trade at a slight premium to NAV. Our top picks include Avalon Bay Communities
(AVB, $33, Strong Buy) and BRE Properties (BRE, $24, Strong Buy).

DETAILS

IRVINE APARTMENT COMMUNITIES COULD GO PRIVATE. The Irvine Company (TIC), which
owns a majority 55% interest of Irvine Apartment Communities LP and 17% of the
shares of Irvine Apartment Communities Inc. (IAC, a real estate investment
trust), announced an offer to IAC's board to acquire the remaining 16.6 million
shares of IAC it does not already own. IAC is unusual in that the REIT is a
minority owner of the operating partnership. TIC intends to pay $32.50 per
share. The shares closed on December 1, 1998, just prior to the announcement, at
$27 3/8.

THE DECISION POINTS TO SEVERAL CHALLENGES FACING MULTIFAMILY REITS

TODAY. The Irvine Company offered several reasons for its decision. On one hand,
it believes a private company is better situated to handle development risks. On
the other, raising new capital has become expensive. The decision to take the
REIT private points to some of the limitations affecting multifamily REITs
today. We think it also confirms our belief that many companies are trading at
or below net asset value.

In general, distributing at least 95% of net income, and in most cases, 70-80%
of cash flow after reserving for recurring capital expenditures, leaves little
in the way of retained earnings to reinvest in the company. With many companies
trading at or below net asset value, selling new equity can be expensive.
Combined with historically low leverage levels, many multifamily REITs have lost
their low cost of capital advantage, especially if capital continues to flow to
private players.

WHILE GOING PRIVATE MAY SERVE AS A CATALYST FOR THE SECTOR... IAC is the first
company in our multifamily universe to commence with plans to go private. To the
degree management has stepped up and indicated it sees more value in the REIT
than the public markets give credit for, investors may pay greater attention to
the sector. Most of the companies in our universe are trading at or below our
estimate for net asset value. There are two stocks we have rated Outperform that
are trading approximately 20% below our estimated net asset value. They are
Berkshire Realty (BRI, $10) and Summit Properties (SMT, $17)

 ... IAC WAS A UNIQUE SITUATION. IAC was the only company we track whereby the
REIT owned a minority interest in the operating partnership. Moreover, the
Irvine Company appears very well capitalized and clearly has the

wherewithal to carry out the transaction. By leaving the operating partnership
intact it does not have to refund the partnership's debt and preferred
securities. Even if another management team wanted to take its company private,
debt costs may still be prohibitive.

WE DERIVE A 7.75% CAP RATE FOR THE TRANSACTION. At $32.50 per share, we believe
the company's income is being valued at approximately a 7.75% cap rate. We had
used an 8% cap rate in coming up with our $31 net asset value (NAV). Assets in
California are generally valued more highly than other areas of the country
given favorable demographics and high barriers to new construction. IAC was
particularly interesting because the Irvine Company owns the Irvine Ranch in
Orange County, which is the largest master planned community in the U.S. The
REIT had an exclusive right to develop multifamily communities on the ranch,
effectively giving it a local monopoly on new development. We presume that the
Irvine Company saw even greater value to the REIT or future development to
justify the price offered for the shares.

WE BELIEVE BETTER-QUALITY COMPANIES OUGHT TO TRADE AT PREMIUMS TO NAV. We think
the better-managed companies with strong balance sheets, low payout ratios, and
exposure to attractive markets ought to be able to trade at a premium to NAV.
Alternatively, when a company's strategy is not embraced by investors the stock
may trade below NAV. Over time, the difference may determine which multifamily
REITs can issue equity on a cost-effective basis and continue to grow through
acquisitions and development compared to those that may be precluded from
raising cheap capital.

We maintain our cautious near-term outlook for companies with exposure to
markets that may experience oversupply problems during 1999 such as Dallas,
Houston, and Orlando. While we expect apartment starts to slow by year-end and
through the early part of next year, recent increases in starts could contribute
to market weakness during 1999 as new communities are completed. We think the
supply outlook ought to improve in 2000.

TOP PICKS: AVB and BRE. We would continue to focus on companies with exposure to
markets that have been undersupplied and with high barriers to entry. Our top
picks include Strong Buy rated Avalon Bay Communities (AVB, $33) and BRE
Properties (BRE, $24). Avalon Bay has a national presence through exposure to
West Coast, Midwest, Mid-Atlantic, and Northeast markets. BRE's portfolio is
located primarily in West Coast markets.
