                              EMPLOYMENT AGREEMENT

                  EMPLOYMENT AGREEMENT, dated as of February 16, 2000, by and
between Lennar Corporation, a Delaware corporation (the "Company"), and Isaac
Heimbinder (the "Executive").

                  WHEREAS, the Company wishes to employ the Executive and the
Executive is willing to serve in the employ of the Company for the period and
upon the terms and conditions specified herein.

                  NOW, THEREFORE, in consideration of the mutual promises set
forth below, the Company and the Executive agree as follows:

1.   Effectiveness. This Agreement shall be effective, and the Company shall
employ the Executive, and the Executive shall be employed by the Company, as of
the Effective Time (the "Effective Time"), as such term is defined in the Merger
Agreement among the Company, LEN Acquisition Corporation and U.S. Home
Corporation, dated as of February 16, 2000 (the "Merger Agreement"). If the
Effective Time does not occur, this Agreement shall be null and void and of no
effect.
<PAGE>   2
2.   Employment and Duties. The Executive shall be employed by the Company as
Executive Vice President of E-Commerce and the Chief Executive Officer and the
Chairman of the board of directors of Strategic Technologies, Inc. in Houston,
Texas, and as a member of the board of directors of the Company (the "Board")
for the term of this Agreement. The Executive shall have such duties,
responsibilities and authority as may from time to time be assigned by the
Company's Chief Executive Officer and the Board that are consistent with and
normally associated with the position of chief executive officer of a subsidiary
of a public company and a senior executive engaged in developing e-commerce
activities for such a company. The Executive shall report only to the Company's
Chief Executive Officer. In these capacities, the Executive shall devote
substantially all of his business time and energies to the business of the
Company and shall perform such services as shall from time to time be assigned
to him, provided that the Executive may serve as a director or officer of any
trade association, civic, educational, religious or charitable organization he
deems appropriate, to the extent that such efforts do not interfere with his
duties hereunder to any material extent. Until the Company's 2003 Annual Meeting
of Stockholders or until termination of the Employment Term, if earlier, the
Company shall nominate the Executive for election to the Board and shall use its
best efforts to cause Executive to be elected as a member of the Board.

3.   Term. Except as otherwise provided herein, the term of the Executive's
employment hereunder shall begin on the Effective Time (the "Commencement Date")
and shall continue until the third anniversary thereof (the "Employment Term"),
unless earlier terminated pursuant to the terms hereof.

4.  Compensation and Benefits.

(a)  As an inducement to enter into this Agreement and for other good and
valuable consideration, the Executive shall be entitled to receive a cash
payment of $10,000,000. Such payment shall be made at the Effective Time, unless
the Executive and the Company agree to a different method and/or timing of
payment prior to the Effective Time.
<PAGE>   3
(b)  Annual Compensation. During each calendar year of the Employment Term, the
Company shall pay the Executive: (i) a base salary (the "Base Salary") at a rate
of at least $800,000 per year, payable in accordance with the Company's normal
payroll practices, but no less often than monthly, and (ii) a cash bonus (the
"Bonus") of $1,200,000 with respect to calendar year 2000, and of at least
$1,000,000 with respect to each of 2001 and 2002. Notwithstanding the foregoing,
the Executive's Base Salary and Bonus shall be subject to review by the Board
each year and may be increased (but not decreased) at any time. If Base Salary
is increased at any time, in any subsequent year Base Salary shall be the
increased amount. Any Bonus shall be payable as promptly as practicable after
the end of the period for which it is being paid, but in any event by April 15th
of the following year.
<PAGE>   4
(c)  Stock Options. As of the Effective Time, the Executive shall be granted an
option (the "Option") to purchase 100,000 shares of the Company's common stock
(the "Common Stock") at the closing price per share of the Common Stock on such
date. Such Option shall be granted under a Company stock option plan, and shall
be an "incentive stock option" within the meaning of Section 422 of the Internal
Revenue Code of 1986 (the "Code") to the extent permitted by Section 422(d) of
the Code; to the extent not permitted by Section 422(d), the remaining portion
of the Option shall be a nonqualified stock option. The Option shall vest and
become exercisable at the rate of 33-1/3% per year, beginning on the first
anniversary of the Commencement Date, and, except as otherwise provided herein,
shall remain exercisable for ninety (90) days following the Executive's
termination of employment for any reason (other than for Cause, in which event
the Option shall terminate on the termination of employment date) or, if less,
the remaining term of the Option. The Option shall have a term of five (5) years
from the date on which it is granted.
<PAGE>   5
(d)  Retirement Benefit. The Company acknowledges (a) that, under all
circumstances (including but not limited to, termination for Cause hereunder),
the Executive is entitled to the retirement benefit as described in his
employment agreement with U.S. Home Corporation as in effect as of the day
immediately preceding the date hereof (the "USH Employment Agreement"), provided
that, after the Effective Time, such benefit shall be calculated on the basis of
Base Salary of $800,000 per annum, (b) the existence of a trust fund created
pursuant to a Trust Agreement, dated as of December 18, 1986 between U.S. Home
Corporation, as grantor, and William E. Reichard, as successor trustee (the
"1986 Trust") and certain annuity contracts purchased pursuant thereto, and (c)
that it consents to an additional contribution by U.S. Home Corporation or the
Company to the 1986 Trust at or prior to the Effective Time sufficient to
provide the full retirement benefit payable to the Executive under such prior
employment agreement and hereunder, provided that such amount shall not exceed
$1,000,000 in the aggregate. The Company and the Executive agree that the
retirement benefit will be payable in all cases in the first instance from the
1986 Trust.

(e)  Expense Reimbursement. The Company shall promptly pay, or reimburse the
Executive for, all ordinary and necessary business expenses incurred by him in
the performance of his duties hereunder, provided that the Executive properly
accounts for them in accordance with Company policy.

(f) Other Benefit Plans, Fringe Benefits, and Vacations. Effective as of the
Effective Time, the Executive shall, upon satisfying the eligibility
requirements therefor (which shall be waived in the case of plans, policies and
arrangements which are not tax-qualified) immediately become a participant in
each of the Company's present employee benefit plans, policies or arrangements
in which the Company's senior executive officers of similar status ("Executive
Officers") participate (or, if the terms are more favorable, in the medical
plans in which the Executive participated immediately prior to the Effective
Time). The Executive shall be granted full credit for his service with U.S. Home
Corporation immediately prior to the Effective Time
<PAGE>   6
with respect to all such present plans, policies and arrangements, to the extent
consistent with all applicable tax-qualification requirements (without the need
to provide any benefits or other improved provisions to any other employee), and
any such plans, policies or arrangements that the Company may maintain or
establish during the Employment Term and receive all fringe benefits and
vacations for which his position makes him eligible in accordance with the
Company's usual policies and the terms and provisions of such plans, policies or
arrangements. The Company shall not terminate or change, in such a way as to
adversely affect the Executive's rights or reduce his benefits (unless such
decrease is required by law to maintain tax-qualified status, or is generally
applicable to employees eligible to participate in any such plan, policy or
arrangement), any employee benefit plan, policy or arrangement in effect as of
the date hereof or which may hereafter be established and in which the Executive
is eligible to participate.

(g)   Continued Medical Coverage. From and after the last day of the Employment
Term, the Executive, his spouse and eligible dependents shall be entitled to
participate in each of the Company's employee benefit plans, policies or
arrangements which provide medical coverage and similar benefits to the
Company's Executive Officers (the "Company Medical Plan") on the same basis as
the Company's other Executive Officers until the last day of the month on which
the Executive becomes eligible for Medicare or other applicable law, provided
that if such coverage may be obtained through a medical plan maintained by U.S.
Home Corporation, the Executive may determine that such coverage should be
obtained (and the Company or U.S. Home Corporation shall bear the cost of such
additional coverage, up to $5,000 per year). The Executive will pay to the
Company the premium charged the Company for such coverage by the time the
Company is required to make payment of such premium, or through any arrangement
mutually acceptable to the Company and the Executive. If continued coverage
under the Company's Medical Plan is not possible under the terms of any
insurance policy or applicable law following the Employment Term, the Company
will use its best efforts to provide the Executive with coverage equivalent to
that provided to the Company's other
<PAGE>   7
Executive Officers under an insurance policy or arrangement acceptable to the
Executive, and the Executive shall reimburse the Company for the cost of such
coverage. With respect to any type of benefit covered by this Section 4(g), such
benefit shall not be required to be provided if the Executive obtains subsequent
employment (including acting as an independent contractor) and such type of
benefit is made available in connection therewith.

(h)   Office Space. For a period of three (3) years from the end of the
Employment Term or, if earlier, the date of the Executive's termination of
employment for any reason other than Cause, Total Disability or death, the
Company shall provide the Executive with (i) an office (at a location at which
the Company then maintains offices) that is comparable in size and stature to
the office he maintained at the Commencement Date, and (ii) a full-time
secretary. The cost of such office and secretary shall be borne entirely by the
Company.
<PAGE>   8
(i)   Deferred Compensation. The Executive has deferred certain amounts (the
"Deferred Compensation") while employed in his prior position in order that the
payment of such amounts would not be nondeductible under Section 162(m) of the
Code by his prior employer. The Deferred Compensation shall continue to be so
deferred until such time as its payment will not result in such a loss of
deduction by the Company, which determination may be evidenced by an opinion of
Kaye, Scholer, Fierman, Hays & Handler, LLP or other law firm reasonably
acceptable to the Company. Upon the receipt and acceptance of such opinion, the
Company shall pay the Executive the amount of such Deferred Compensation in a
single lump sum in cash as promptly as possible (but in no event more than
thirty (30) days after receipt of the opinion).

5.  Termination.

(a)   Compensation and Benefits. Upon termination of the Executive's employment
(including the Executive's voluntary termination), in addition to any other
benefits he or his estate, as applicable, shall be entitled to receive hereunder
(i) any Base Salary or other benefit that has accrued but not been paid up to
the date of his termination of employment or for the period required by law,
(ii) unless such termination is for Cause, a pro rata portion of the Bonus
payable with respect to the calendar year of termination, determined by
multiplying the Bonus for such year as set forth in Section 4(b) hereof by a
fraction, the numerator of which is the number of calendar days in such year up
to the termination of employment date and the denominator of which is 365, (iii)
a lump sum in cash for any accrued but unpaid vacation days, and (iv) any unpaid
expense reimbursements. In addition, in the event of the Executive's death
during the Employment Term, his estate or beneficiary shall be entitled to
exercise any then exercisable Option until the earlier of twelve (12) months
following his date of death or the end of the Option term. The provisions of
Section 4 expressly applicable after termination of employment and the
provisions of this Section 5 shall be the Executive's exclusive rights hereunder
in the event of termination.
<PAGE>   9
(b)  Termination on Death and Disability.

(i)   The Executive's employment hereunder shall terminate upon his death or
upon a finding that he has become Totally Disabled. For purposes of this
Agreement, the Executive shall be "Totally Disabled" if he is physically or
mentally incapacitated so as to render him incapable of performing his usual and
customary duties hereunder for a period of six (6) consecutive months or for
shorter periods aggregating six (6) months in any period of twelve (12)
consecutive months. The Executive's receipt of Social Security disability
benefits shall be deemed conclusive evidence of Total Disability for purposes of
this Agreement, provided, however, that in the absence of such Social Security
benefits, Total Disability shall be evidenced by the written determination of a
physician, licensed in the State of Texas, mutually selected by the Board and
the Executive.

(ii)   In the event that the Executive is Totally Disabled or dies before his
retirement benefit pursuant to Section 4(d) hereof has commenced to be
distributed (whether or not he is in the employ of the Company at the time he
dies or is so Totally Disabled), such retirement benefit shall commence to be
distributed to him or his designated beneficiary to the extent and in the manner
provided under the terms of the Executive's USH Employment Agreement and/or the
other documents governing the payment of such retirement benefit as in effect on
the day before the date hereof.

(iii)   In the event of the Executive's death (while Totally Disabled or
otherwise) after his retirement benefit has commenced to be distributed pursuant
to Section 4(d) hereof or subparagraph (ii) above, as applicable, the retirement
benefit shall be paid to his designated beneficiary to the extent and in the
manner provided under the terms of the Executive's USH Employment Agreement
and/or the other documents governing the payment of such retirement benefit as
in effect on the day before the date hereof.

(c)   Termination For Cause. The Executive's employment hereunder may be
terminated for Cause. For purposes of this Agreement, the term "Cause" shall
mean (i) the
<PAGE>   10
Executive's continuing willful failure to perform his duties hereunder (other
than as a result of total or partial incapacity due to physical or mental
illness), (ii) the Executive's gross negligence or gross malfeasance by the
Executive in the performance of his duties hereunder, (iii) an act or acts on
the Executive's part constituting fraud, theft or embezzlement or act that
otherwise constitutes a felony under the laws of the United States or any state
thereof which results or was intended to result directly or indirectly in gain
or personal enrichment by the Executive at the expense of the Company, or
conviction of any felony or crime of moral turpitude, (iv) breach of the
provisions of Section 6(b) hereof, or (v) any other material breach of this
Agreement. In any case described in this section, the Executive shall be given
written notice of the alleged breach in accordance with Section 8(b) hereof,
and, in the case of clauses (i), (ii) and (v) above, the Executive shall have
thirty (30) days from the date of receipt of such notice to cure such breach.
Such notice shall set forth in detail the reason or reasons for such
termination, including any act or failure to act that is the basis for the
decision to terminate the Executive. Within thirty (30) days after the aforesaid
notice, the Executive shall be given an opportunity to make a presentation to
the Board (accompanied by counsel or other representative if so desired) at a
meeting of the Board. Following such meeting, the Board shall determine whether
to terminate the Executive for "Cause" and shall notify the Executive of its
determination.

(d)   Good Reason. The Executive may terminate his employment hereunder for Good
Reason. For purposes of this Agreement, the term "Good Reason" shall mean and be
deemed to exist if, without the Executive's prior written consent, (i) the
Executive is assigned duties or responsibilities that are inconsistent with the
scope of the duties or responsibilities associated with his titles or position
as set forth in this Agreement (or which he may receive during the Employment
Term), (ii) the Executive's duties or responsibilities are significantly
reduced, (iii) the Executive is assigned to report to anyone other than the
Company's Chief Executive Officer, or the Board, (iv) the Company fails to
perform any material term or provision of this Agreement, (v) benefits to which
the Executive is entitled under the Company's benefit plans are
<PAGE>   11
decreased, unless such decrease is required by law to maintain tax-qualified
status or is applicable to all employees of the Company eligible to participate
in any plan so affected, (vi) the Executive's office location is relocated to
one that is more than 10 miles from the location at which the Executive was
based immediately prior to the relocation, (vii) the Executive's title, as of
the Commencement Date, is adversely changed, (viii) the Company fails to obtain
a full assumption of this Agreement by a successor entity in accordance with
Section 8(e) hereof, or (ix) the Executive is not elected (prior to the
Effective Time) or reelected to the Board, or is forced to resign therefrom or
from such title for any reason not constituting Cause. The Executive shall
provide the Company with written notice of the alleged breach in accordance with
Section 8(b) hereof and, in the case of clauses (i), (ii), (iv), (v) and (viii)
above, the Company shall have thirty (30) days from the date of receipt of such
notice to cure such notice. Such notice shall set forth in detail the reason or
reasons for his termination, including any act or failure to act that is the
basis for his decision to terminate for Good Reason.
<PAGE>   12
(e)  Termination for Good Reason or Without Cause. If the Executive's employment
hereunder is terminated without Cause or the Executive terminates for Good
Reason, as soon as practicable (but not later than 30 days) after such
termination, (i) he shall receive a lump sum cash payment equal to the sum of an
amount equal to his highest monthly Base Salary ($66,666 per month for the first
year hereof) and one-twelfth (1/12) of the Bonus paid in the preceding calendar
year (or $100,000 per month if termination occurs in the first year hereof)
multiplied by the number of full or partial months remaining in the Employment
Term, and (ii) any Option held by the Executive shall become immediately
exercisable and shall remain exercisable until the earlier of end of the Option
term or three (3) months following the date of the Executive's termination. In
addition to the foregoing benefits, if the Executive is terminated without Cause
or he terminates for Good Reason, he shall continue to be entitled to
reimbursement for expenses and other benefits following termination of
employment, in the amounts and in the manner set forth in Sections 4(e) and 4(f)
hereof.

(f)  Termination Following a Change in Control.

(i)   In the event the Executive's employment terminates for any reason other
than death, Total Disability or Cause prior to the first anniversary of a Change
in Control of the Company, he shall be entitled to a lump sum cash payment
within ten (10) days of his termination of employment in an amount equal to the
remaining Base Salary and Bonus he would have been paid hereunder for the
remainder of the Employment Term. In addition, Section 6(b) hereof shall not be
applicable to the Executive from and after the date of his termination of
employment.

(ii) For purposes of this Agreement, a Change in Control shall mean the
happening of any of the following:

(1) any "person," as such term is used in Section 13(d) and 14(d) of the
Securities Exchange Act of 1934 (the "Exchange Act") (other than the Company or
any subsidiary of the Company, or any trustee or other fiduciary holding
securities under an
<PAGE>   13
employee benefit plan of the Company or any subsidiary) becomes the "beneficial
owner" (as defined in Rule 13d-3 under the Exchange Act), directly or
indirectly, of securities of the Company representing more than fifty percent
(50%) of the combined voting power of the Company's then outstanding securities;

(2)   during any period of two consecutive years beginning on or after the
Commencement Date, individuals who at the beginning of such period constitute
the Board, and any new director (other than a director designated by a person
who has entered into an agreement with the Company to effect a transaction
described in clause (1), (3) or (4)) whose election by the Board or nomination
for election by the Company's shareholders was approved by a vote of at least
one-half (1/2) of the directors then still in office who either were directors
at the beginning of the period or whose election or nomination for election was
previously so approved (unless the approval of the election or nomination for
election of such new directors was in connection with an actual or threatened
election or proxy contest), cease for any reason to constitute at least a
majority thereof;

(3)   the shareholders of the Company approve a merger or consolidation of the
Company with any other corporation, other than (x) a merger or consolidation
which would result in the voting securities of the Company outstanding
immediately prior thereto continuing to represent (either by remaining
outstanding or by being converted into voting securities of the surviving
entity) more than fifty percent (50%) of the combined voting power of the voting
securities of the Company or such surviving entity outstanding immediately after
such merger or consolidation or (y) a merger or consolidation effected to
implement a recapitalization of the Company (or similar transaction) in which no
"person" (as defined above in clause (1)) acquires more than fifty percent (50%)
of the combined voting power of the Company's then outstanding securities; or

(4)   the shareholders of the Company approve a plan of complete liquidation of
the Company or an agreement for the sale or disposition by the Company of all or
<PAGE>   14
substantially all of the Company's assets or any transaction having a similar
effect. Notwithstanding the foregoing, no transfer of a security to a "Permitted
Holder" shall give rise to, or otherwise be taken into account for purposes of
determining whether there has occurred, a Change in Control. For these purposes,
a "Permitted Holder" shall mean any holder of the Company's Class B Common Stock
as of the Effective Time and any permitted transferee of the Company's Class B
Common Stock under the terms of the Company's Certificate of Incorporation, as
it exists as of the Effective Time.

(g)   No Mitigation, No Offset. In the event of any termination of the
Executive's employment under this Section 5, the Executive shall be under no
obligation to seek other employment and there shall be no offset against any
amounts due the Executive under this Agreement on account of any remuneration
the Executive may obtain from any subsequent employment. Any amounts due under
this Section 5 are in the nature of liquidated damages, and not in the nature of
a penalty.

6.       Covenants.

(a)  Confidentiality. The Executive acknowledges that he has acquired and will
acquire confidential information respecting the business of the Company.
Accordingly, the Executive agrees that, without the written consent of the
Company as authorized by the Board, he will not, at any time, willfully disclose
any such confidential information to any unauthorized third party. For this
purpose, information shall be considered confidential only if such information
is uniquely proprietary to the Company and has not been made publicly available
prior to its disclosure by the Executive.

(b)  Competitive Activity. Until the end of the Employment Term, the Executive
shall not, without the consent of the Board, directly or indirectly, knowingly
engage or be interested in (as owner, partner, shareholder, employee, director,
officer, agent, consultant or otherwise), with or without compensation, any
business which (i) is in competition with any line of business that U.S. Home
Corporation or any of its affiliates or subsidiaries conducted
<PAGE>   15
immediately prior to the Effective Time, or (ii) shall hire any person who was
employed by the Company or any of its affiliates or subsidiaries within the
six-month period preceding such hiring, except for any employee whose annual
rate of compensation is not in excess of $55,000. Nothing herein, however, shall
prohibit the Executive from acquiring or holding not more than one percent of
any class of publicly traded securities of any such business.
<PAGE>   16
(c)  Remedy for Breach. The Executive acknowledges that the provisions of this
Section 6 are reasonable and necessary for the protection of the Company and
that the Company will be irrevocably damaged if such covenants are not
specifically enforced. Accordingly, the Executive agrees that, in addition to
any other relief to which the Company may be entitled, the Company shall be
entitled to seek and obtain injunctive relief (without the requirement of any
bond) from a court of competent jurisdiction for the purposes of restraining the
Executive from any actual or threatened breach of such covenants.

7.       Change in Control Payments
<PAGE>   17
(a)   Gross-Up Payment. Notwithstanding anything herein to the contrary, in the
event that any payments to the Executive pursuant to this Agreement or under any
other agreement, plan or arrangement of the Company (the "Change in Control
Payments") become subject to the tax imposed by Section 4999 of the Code (the
"Excise Tax"), the Company shall pay to the Executive at the time specified
below, an additional cash amount (the "Gross-Up Payment") such that the net
amount retained by the Executive after deduction of any Excise Tax on the Change
in Control Payments and any federal, state and local income tax and Excise Tax
upon the payment provided by this paragraph, shall be equal to the Change in
Control Payments. For purposes of determining whether any of the Change in
Control Payments will be subject to the Excise Tax and the amount of such Excise
Tax, (a) any other payments or benefits received or to be received by the
Executive in connection with a Change in Control of the Company or U.S. Home
Corporation shall be treated as "parachute payments" within the meaning of
Section 280G of the Code, and all "excess parachute payments" within the meaning
of such Section 280G shall be treated as subject to the Excise Tax, unless in
the opinion of tax counsel selected by the Company's independent auditors and
acceptable to the Executive, such other payments or benefits (in whole or in
part) do not constitute parachute payments, or such excess parachute payments
(in whole or in part) represent reasonable compensation for services actually
rendered within the meaning of Section 280G of the Code, and (b) the value of
any non-cash benefits or any deferred payment or benefits shall be determined by
such independent auditors in accordance with the principles of Section 280G of
the Code. For purposes of determining the amount of the Gross-Up Payment, the
Executive shall be deemed to pay federal income taxes at the highest marginal
rate of federal income taxation in the calendar year in which the Gross-Up
Payment is to be made and state and local income taxes at the highest marginal
rates of taxation in the state and locality of his residence on the date of his
termination of employment net of the maximum reduction in federal income taxes
which could be obtained from deduction of such state and local taxes.
<PAGE>   18
(b)   Overpayment of Gross-Up Payment. In the event that the Company furnishes
the Executive with a written opinion of its independent accountants (reasonably
satisfactory to the Executive) that the Excise Tax due has been subsequently
determined to be less than the amount taken into account hereunder at the time a
Gross-Up Payment was paid, the Executive shall repay to the Company at the time
that the amount of such reduction in Excise Tax is finally determined, the
portion of the Gross-Up Payment attributable to such reduction plus interest on
the amount of such repayment at the rate provided in Section 1274(b)(2)(B) of
the Code. Notwithstanding the foregoing, if any portion of the Gross-Up Payment
to be refunded to the Company has been paid to any federal, state or local tax
authority, repayment thereof shall not be required until an actual refund or
credit of such portion has been made to or obtained by the Executive from such
tax authority, and any interest payable to the Company shall not exceed the
interest received or credited to the Executive by any such tax authority. The
Executive shall be fully indemnified by the Company for any out-of-pocket costs,
expenses or fees attributable to the filing of any refund or other claim.

(c)   Underpayment of Gross-Up Payment. In the event the Executive notifies the
Company that the Excise Tax has been determined (by the Internal Revenue
Service) to exceed the amount taken into account hereunder at the time a
Gross-Up Payment was made (including by reason of any payment the existence or
amount of which cannot be determined at the time of the Gross-Up Payment), the
Company shall make an additional Gross-Up Payment in respect of such excess
Excise Tax (plus any interest payable with respect to such excess) at the time
that the amount of such excess is finally determined.
<PAGE>   19
(d) Timing of Payment. Any Gross-Up Payment shall be paid to or on behalf of the
Executive not later than ten (10) business days following the payment of any
Change in Control Payments which are subject to Section 4999 of the Code.

                           Attention: David W. Bernstein, Esq.

(c)  Entire Agreement; Amendment. This Agreement shall supersede any and all
existing agreements between the Executive and the Company or any of its
affiliates or subsidiaries relating to the terms of his employment; provided,
however, that this Agreement shall not supersede or adversely impair in any way
the right of the Executive and his designated beneficiary to receive the
retirement benefit as described in his USH Employment Agreement and/or the other
documents governing the payment of such retirement benefit as in effect on the
day before the date hereof. It may not be amended except by a written agreement
signed by both parties.

(d)  Waiver. The failure of a party to insist upon strict adherence to any term
of this Agreement on any occasion shall not be considered a waiver thereof or
deprive that party of the right thereafter to insist upon strict adherence to
that term or any other term of this Agreement.

(e)  Assignment. Except as otherwise provided in this paragraph, this Agreement
shall inure to the benefit of and be binding upon the parties hereto and their
respective heirs, representatives, successors and assigns. This Agreement shall
not be assignable by the Executive, and shall be assignable by the Company only
to any corporation or other entity resulting from the reorganization, merger or
consolidation of the Company with any other corporation or entity or any
corporation or entity to which the Company may sell all or substantially all of
its assets, and it must be so assigned by the Company to, and accepted as
binding upon it by, such other corporation or entity in connection with any such
reorganization, merger, consolidation or sale.

(f)  Litigation Costs. In the event that the Executive shall successfully
prosecute a judicial proceeding to enforce any provision of this Agreement, in
addition to any other relief awarded the Executive by the court in such action,
the parties agree that the judgment rendered
<PAGE>   21
shall award the Executive all of his attorneys' fees, disbursements and other
costs incurred by the Executive in prosecuting such suit.

(g) Separability. If any provision of this Agreement is invalid or
unenforceable, the balance of the Agreement shall remain in effect, and if any
provision is inapplicable to any person or circumstance, it shall nevertheless
remain applicable to all other persons and circumstances.

(h)   Arbitration. Any and all disputes or controversies arising out of or
relating to this Agreement, other than injunctive relief pursuant to Section
6(c), shall be resolved by arbitration at the American Arbitration Association
at its Houston, Texas offices before a panel of three arbitrators under the then
existing rules and regulations of the American Arbitration Association. The
parties agree that in any such arbitration, the arbitrators shall not have the
power to reform or modify this Agreement in any way and to that extent their
powers are so limited. The determination of the arbitrators shall be final and
binding on the parties hereto and judgment on it may be entered in any court of
competent jurisdiction. In the event Executive prevails in such proceedings, as
determined by the arbitrators, the Company shall reimburse Executive for all
expenses incurred by Executive in connection with such proceeding or any other
proceeding in which Executive prevails in contesting or defending any claim or
controversy arising out of or relating to this Agreement. All such amounts shall
be paid promptly, but in any event within ten (10) business days after Executive
provides the Company with a statement of such amounts to be recovered. In the
event Executive does not prevail in such proceedings, as determined by the
arbitrators, each party hereto shall be responsible for their own expenses
(including, without limitation, legal fees and expenses) incurred in connection
with such proceedings.

                                 March 10, 2000

Lennar Corporation
700 N.W. 107th Avenue
Miami, Florida 33172

Gentlemen/Ladies:

            Lennar Corporation ("Borrower") has requested credit facilities (the
"Facilities") in the aggregate principal amount of $1,300,000,000 (the
"Aggregate Commitment") to finance the acquisition (the "Acquisition") of all of
the issued and outstanding capital stock of U.S. Home Corporation (the "Target")
in exchange for $265,800,000 of Lennar stock and $265,800,000 in cash, the
refinancing of certain indebtedness of Borrower and the Target (including
certain debt securities of the Target) and for other general corporate purposes.

            Bank One, NA, having its principal office in Chicago, Illinois
("Bank One"), and Bankers Trust Company ("BT") are pleased to provide Borrower
with, in the case of Bank One, up to $650,000,000 and, in the case of BT, up to
$650,000,000 of the Aggregate Commitment. Bank One shall be Administrative Agent
and BT shall be Syndication Agent (collectively, the "Agents") on the terms and
conditions set forth in this commitment letter ("Commitment Letter") and the
term sheet attached hereto ("Term Sheet"). Banc One Capital Markets, Inc.
("BOCM"), an affiliate of Bank One, and Deutsche Bank Securities Inc, an
affiliate of BT ("DBSI" and together with BOCM, the "Co-Lead Arrangers"), are
pleased to provide Borrower with their respective undertakings to syndicate all
or a portion of the Facilities to additional lenders (together with the Agents,
the "Lenders"). While Agents' agreement herein is to provide the entire amount
of the Facilities on a fully underwritten basis, Co-Lead Arrangers reserve the
right to syndicate all or a portion of the Facilities to additional Lenders with
a corresponding reduction in the Agents' commitments. The Agents and Co-Lead
Arrangers (and their respective agents, officers and employees) will have the
right to share with each other information received from Borrower's agents,
officers, and employees. The obligations of the Agents hereunder are several and
not joint, and neither of the Agents shall be responsible for the failure of the
other Agent to perform such other Agent's obligations hereunder; provided that
each Agent's commitment to provide a portion of the Facilities is subject to the
other Agent's providing its portion of the Facilities Agent reserves the right
to allocate its commitment among its respective affiliates.

            In addition to the Facilities contemplated by this Commitment
Letter, the Acquisition and the refinancing of certain indebtedness of Borrower
and the Target (including certain debt securities of the Target) will be funded
with the proceeds of $500,000,000 of senior and/or subordinated debt securities
to be issued by the Borrower (the "Debt Securities") or from a $500,000,000
bridge loan to be obtained by the Borrower (the "Bridge Loan") The terms and
conditions of the Debt Securities and the Bridge Loan, including, without
limitation, those pertaining to amortization, interest rate, covenants,
defaults, subordination and standstill must be acceptable to Agents and Co-Lead
Arrangers. In addition, the definitive structure and the

                                     Page 1
<PAGE>   2

financial, legal, accounting and tax aspects of the Acquisition must be
satisfactory to Agents and Co-Lead Arrangers.

            Agents and Co-Lead Arrangers have reviewed certain historical and
pro forma financial statements of Borrower and Target and other materials
provided by Borrower. Agents and Co-Lead Arrangers have not had the opportunity
to complete their due diligence review, inspection, and evaluation of the assets
and liabilities of the Target and Borrower and their respective subsidiaries,
and their respective financial condition and prospects. Agents' commitments and
Co-Lead Arrangers' undertakings are subject to their respective satisfaction
with the foregoing and to the continuing satisfaction therewith and the
satisfaction of such other due diligence investigation as may be necessary for
their respective evaluation.

            Borrower agrees (i) to reimburse Agents and Co-Lead Arrangers for
all out-of-pocket expenses (including the fees of outside counsel and time
charges for inside counsel) incurred in connection with this Commitment Letter,
Fee Letter (as hereinafter defined), and the Term Sheet (the Commitment Letter,
Fee Letter and Term Sheet collectively the "Commitment"), the transactions
contemplated by the Commitment, and Agents' and Co-Lead Arrangers' ongoing due
diligence, including without limitation travel expenses and costs incurred in
connection with the preparation, negotiation, execution, administration,
syndication, and enforcement of any document relating to this transaction and
Agents' and Co-Lead Arrangers' roles hereunder, (ii) to indemnify and hold
harmless the Agents, Co-Lead Arrangers, Lenders and their respective officers,
employees, agents, attorneys, directors, and affiliates (collectively, the
"Indemnified Persons") against any and all losses, claims, damages, or
liabilities of every kind whatsoever to which the Indemnified Persons may become
subject in connection in any way with the transaction which is the subject of
the Commitment, including without limitation expenses incurred in connection
with investigating or defending against any liability or action whether or not a
party thereto, except to the extent any of the foregoing is found in a final
judgment by a court of competent jurisdiction to have arisen from such Lender's
gross negligence or willful misconduct; and (iii) that no Indemnified Person
shall have any liability to Borrower for consequential damages on any theory of
liability in connection in any way with the transaction which is the subject of
the Commitment. The obligations described in this paragraph are independent of
all other obligations of Borrower hereunder and under the Loan Documents (as
defined in the Term Sheet), shall survive the expiration, revocation or
termination of the Commitment, and shall be payable whether or not the financing
transactions contemplated by the Commitment shall close. Agents' and Co-Lead
Arrangers' respective obligations under the Commitment are enforceable solely by
the party signing the Commitment and may not be relied upon by any other person.
If the commitment, or any act, omission or event described in this paragraph
becomes the subject of a dispute, the parties hereto each hereby waive trial by
jury. For purposes of this paragraph, the terms "Agents" and "Co-Lead Arrangers"
shall include any affiliate of either.

            Co-Lead Arrangers will, in consultation with Borrower, manage all
aspects of the syndication, including, without limitation, decisions as to the
selection of institutions to be approached and when they will be approached,
when their commitments will be accepted, which institutions will participate,
the allocations of the commitments among the Lenders and the amount and
distribution of the fees discussed herein among the Lenders. Upon Co-Lead
Arrangers' acceptance of any such commitment from a Lender, Agents shall be
relieved of their

                                     Page 2
<PAGE>   3

respective commitments to fund such amount on a pro rata basis. To assist
Co-Lead Arrangers in their syndication efforts, Borrower shall (a) provide and
to cause its advisors to provide Co-Lead Arrangers upon request with all
information deemed reasonably necessary by it to complete successfully the
syndication, including, without limitation, all information and projections
prepared by Borrower or on Borrower's behalf relating to the transactions
contemplated hereby, (b) cause the management of the Borrower to actively
participate in, both the preparation of an information package regarding the
operations and prospects of the Borrower and the presentation of the information
to prospective Lenders; and (c) not make any statement publicly about the
Commitment or the Facilities which might negatively affect Co-Lead Arrangers'
ability to syndicate the Facilities. Borrower will also, if Co-Lead Arrangers so
request, assist Co-Lead Arrangers in the process of obtaining for Borrower a
credit rating from a nationally recognized rating agency (and Borrower will pay
the reasonable fees and out-of-pocket expenses incurred in connection with
obtaining such a rating).

            Agents and Co-Lead Arrangers shall be entitled, after consultation
with Borrower, to change any or all of the structure, terms or pricing of the
Facilities if the syndication has not been completed and if Agents and Co-Lead
Arrangers determine that such changes are advisable in order to ensure a
successful syndication of the Facilities; provided that the amount of the
Facilities remains unchanged. Co-Lead Arrangers' undertakings and Agents'
commitments hereunder are subject to the agreements in this paragraph.

            Borrower authorizes each of Agents and Co-Lead Arrangers to answer
inquiries from the media with respect to the Facilities and to issue press
releases with respect to the Facilities. Borrower hereby authorizes each of
Agents and Co-Lead Arrangers, at their respective sole expense but without any
prior approval by Borrower, to publish such tombstones and give such other
publicity to the Facilities as each may from time to time determine in its sole
discretion. The foregoing authorizations shall remain in effect unless the
Borrower notifies each in writing that such authorization is revoked.

            Please indicate your acceptance of the Commitment by Agents and
undertaking by Co-Lead Arrangers in the space indicated below and return a copy
of this letter so executed to Agents and Co-Lead Arrangers. The Commitment and
undertaking will expire at 5 p.m (Chicago time) March 14, 2000, unless on or
prior to such time Agents and Co-Lead Arrangers shall have received a copy of
this letter executed by Borrower. Notwithstanding timely acceptance of the
Commitment pursuant to the preceding sentence, the Commitment will automatically
terminate unless definitive Loan Documents are executed and the Acquisition is
consummated on or before June 3, 2000. By its acceptance hereof, Borrower agrees
to pay Agents and Co-Lead Arrangers the fees described in the fee letters
(collectively, the "Fee Letter") of even date herewith.

            By accepting delivery of this letter, Borrower hereby agrees that,
prior to the execution hereof, Borrower will not disclose, either expressly or
impliedly, without Agents' and Co-Lead Arrangers' consent, to any person any of
the terms of the Commitment, or the fact that the Commitment or the financing
proposal represented thereby exists except that Borrower may disclose any of the
foregoing to any employee, financial advisor (but not to any financial advisor
which may be a provider of debt in this transaction) or attorney of Borrower to
whom, in each case, it is necessary to disclose such information, so long as any
such employees, advisors or attorneys are directed to observe

                                     Page 3
<PAGE>   4

this confidentiality obligation. Upon Borrower's execution of this Commitment
Letter, Borrower may make public disclosure of the existence and the amount of
the Aggregate Commitment, and Borrower may publicly file a copy of the
Commitment Letter and Term Sheet (but not the Fee Letter), or make such other
disclosures if such disclosure is, in the opinion of Borrower's counsel,
required by law. Without Limiting the generality of the foregoing, Borrower will
not make a public disclosure of the Fee Letter without a written opinion of its
counsel indicating such disclosure is required by law or regulation. If Borrower
does not accept the Commitment, Borrower is to immediately return it and all
copies of it to Administrative Agent.

            Agents' and Co-Lead Arrangers' agreement hereunder is separate and
distinct from BOCM's and DBSI's agreement to act as Borrower's joint lead
managers in connection with the Debt Securities or the commitment of Bankers
Trust Corporation and First Chicago Capital Corporation to make the Bridge Loan.
Borrower has directed Agents and Co-Lead Arrangers that those personnel of
Agents and Co-Lead Arrangers working on the commitment hereunder and those
working on the private placement of the Debt Securities and those personnel of
Bankers Trust Corporation and First Chicago Capital Corporation working on the
Bridge Loan should share the Borrower's confidential information with each other
and generally work together on this transaction. Borrower acknowledges and
consents to these units acting in these multiple roles, and further acknowledges
that the fact that affiliates of the Agents are providing placement services or
bridge loan financing to Borrower does not mean that the terms of any such
proposal (i) are acceptable to Agents or Co-Lead Arrangers in their capacities
as such or as Lenders or (ii) are or will be acceptable to any other Lenders.

            Each Agent reserves the right to assign some or all of its rights
and delegate some or all of its responsibilities hereunder to one of its
affiliates. This letter and Term Sheet supersede any and all prior versions
thereof. This letter shall be governed by the internal laws of the State of New
York, and may only be amended by a writing signed by all parties.
