This Proxy Statement/Prospectus is being furnished in connection with
the solicitation by the Board of Directors of National Health Laboratories
Incorporated (the "Company") of proxies to be voted at the annual meeting of
stockholders to be held on the 7th day of June 1994 at 10:30 a.m., local time,
at the Sheraton Music City Hotel, 777 McGavock Pike at Century City, Nashville,
Tennessee 37214, and at any adjournments thereof. This Proxy
Statement/Prospectus is first being sent to stockholders on or about
April 26, 1994.

At the annual meeting, the Company's stockholders will be asked (1) to
approve the Agreement and Plan of Merger attached as Exhibit A hereto (the
"Plan of Merger"), (2) to elect the following persons as directors of the
Company until the Company's next annual meeting and until such directors'
successors are elected and shall have qualified: Ronald O. Perelman, Saul J.
Farber, M.D., Howard Gittis, Ann Dibble Jordan, James R. Maher, David J.
Mahoney, Paul A. Marks, M.D., Linda Gosden Robinson and Samuel O. Thier, M.D.,
(3) to ratify the selection of KPMG Peat Marwick as the Company's independent

Incorporated 1994 Stock Option Plan (the "1994 Option Plan") and (5) to take
such other action as may properly come before the annual meeting or any
adjournments thereof.

The Board of Directors of the Company is recommending approval of the
Plan of Merger in connection with a proposed corporate reorganization that will
create a holding company structure for the Company. National Health
Laboratories Holdings Inc. ("NHL Holdings"), a wholly owned subsidiary of the
Company that has been newly formed specifically to effect the reorganization,
will become the parent holding company of the Company. All outstanding shares
of common stock of the Company will be converted on a share-for-share basis
into shares of common stock of NHL Holdings. As a result, the owners of common
stock of the Company will become the owners of common stock of NHL Holdings.
Subsequent to the reorganization, the Company will continue to carry on its
present business as a subsidiary of NHL Holdings. The Company believes the
reorganization will provide increased alternatives available for future
financing. See "Proposed Reorganization--Reasons for Reorganization."

Incorporation and By-laws of NHL Holdings" and "--Description of NHL Holdings'
Common Stock" for further information concerning the securities offered hereby.

Plan.

PROPOSED REORGANIZATION

GENERAL

The Board of Directors of the Company has unanimously approved, and
recommended that the stockholders approve, a proposed corporate reorganization
pursuant to the Plan of Merger. The reorganization will create a parent holding
company and convert the Company's outstanding common stock into common stock of
the new holding company on a share-for-share basis. The affirmative vote of a
majority of the outstanding shares of the Company's common stock is required
for approval of the Plan of Merger.

THE BOARD OF DIRECTORS OF THE COMPANY RECOMMENDS THAT STOCKHOLDERS VOTE
FOR APPROVAL OF THE PLAN OF MERGER.

THE COMPANY AND NHL HOLDINGS

The Company is one of the leading clinical laboratory companies in the
United States. Through a national network of laboratories, the Company offers a
broad range of testing services used by the medical profession in the
diagnosis, monitoring and treatment of disease. The Company's principal
executive offices are located at 4225 Executive Square, Suite 800, La Jolla,
California 92037, and its telephone number is (619) 550-0600.

NHL Holdings, a newly formed, wholly owned subsidiary of the Company,
was organized under the laws of the State of Delaware specifically for the
purpose of becoming the new parent holding company in the reorganization. Its
executive offices are located at the Company's principal executive offices
referred to above. NHL Holdings has newly formed a wholly owned subsidiary, NHL
Sub Acquisition Corp. ("NHL Acquisition"), specifically to effect the
reorganization. Neither NHL Holdings nor NHL Acquisition has any significant
assets or capitalization nor has engaged in any business or prior activities
other than in connection with the reorganization. The formation of the holding
company structure will be accomplished through the merger of NHL Acquisition
with and into the Company, at which time the outstanding common stock of the
Company will be deemed converted into common stock of NHL Holdings on a share-
for-share basis. The form of the Plan of Merger is attached hereto as Exhibit A
and is incorporated herein by reference.

If the Plan of Merger is approved by the stockholders and not
terminated by the Board of Directors of NHL Holdings, the reorganization will
become effective at the close of business on the date that an appropriate
certificate of merger is filed with the Delaware Secretary of State as required
by Delaware law. The Company anticipates that the reorganization will become
effective promptly following the annual meeting.

Immediately following the effective time of the reorganization, NHL
Holdings will have the same consolidated assets, liabilities and stockholders'
equity and the same directors and executive officers as the Company had
immediately prior to such date. In addition, there will be no change in the
state of incorporation from the Company to NHL Holdings since both companies
are Delaware corporations with substantially identical certificates of
incorporation and By-laws. NHL Holdings expects to continue the Company's
current quarterly dividend policy.
TERMS OF REORGANIZATION; CONDITIONS TO CONSUMMATION OF THE REORGANIZATION

Pursuant to the Plan of Merger:

(i) NHL Acquisition will be merged into the Company, with the
Company being the surviving corporation.

(ii) Except as set forth in paragraph (iv) below, each
outstanding share of the Company's common stock will be changed and converted
into one share of common stock of NHL Holdings.
6

(iii) The outstanding shares of common stock of NHL Acquisition
will be changed and converted into the shares of the surviving corporation.

(iv) The outstanding shares of NHL Holdings' common stock and
the Company's common stock held by the Company prior to the time the
reorganization is effected will be cancelled.

As a result of the foregoing, the Company, as the surviving corporation
in the merger, will become a subsidiary of NHL Holdings, and all the common
stock of NHL Holdings outstanding immediately after the merger will be owned by
the former common stockholders of the Company. The Company will continue to own
all outstanding stock of its existing subsidiaries.

As of the effective time of the reorganization, the stockholders of the
Company prior to the effective time will automatically become owners of NHL
Holdings' common stock and, as of the effective time, will cease to be owners
of the Company's common stock. Stock certificates representing shares of the
Company's common stock will, at the effective time, automatically represent
shares of NHL Holdings' common stock. Stockholders of the Company's common
stock will not be required to exchange their stock certificates as a result of
the reorganization. Should a stockholder desire to sell shares of NHL
Holdings' common stock after the effective time, delivery of the stock
certificate or certificates which previously represented shares of the
Company's common stock will be sufficient.

Following the reorganization, certificates bearing the name of NHL
Holdings will be issued in the normal course upon surrender of outstanding
Company common stock certificates for transfer or exchange. If any stockholder
surrenders a certificate representing shares of the Company's common stock for
exchange or transfer and the new certificate to be issued is to be issued in a
name other than that appearing on the surrendered certificate theretofore
representing the Company's common stock, it will be a condition to such
exchange or transfer that the surrendered certificate be properly endorsed and
otherwise be in proper form for transfer and that the person requesting such
exchange or transfer either (i) pay NHL Holdings or its agents any taxes or
other governmental charges required by reason of the issuance of a certificate
registered in a name other than that appearing on the surrendered certificate
or (ii) establish to the satisfaction of NHL Holdings or its agents that such
taxes or other governmental charges have been paid.

The reorganization will not be consummated unless the following
conditions are satisfied: (i) approval of the Plan of Merger by the requisite
vote of stockholders of the Company; (ii) receipt of an opinion of Cravath,
Swaine & Moore, counsel to NHL Holdings and the Company, with respect to the
federal income tax consequences of the reorganization; and (iii) effectiveness
of the Registration Statement covering the shares of NHL Holdings' common stock
to be used in connection with the reorganization.

REASONS FOR REORGANIZATION

The Company has considered and continues to consider acquisitions of
laboratory companies of varying sizes, although there are currently no
definitive plans with respect to any significant acquisition. In that
connection, the agent under the Company's existing revolving credit facility
suggested that a holding company structure would provide a greater degree of
flexibility in structuring financings, and thereby permit borrowing from banks,
other financial institutions or from the securities markets more readily and on
more favorable terms than presently available to the Company. NHL Holdings
could borrow funds directly and contribute them to the Company, securing such
borrowings with a pledge of all the capital stock of the Company.
Alternatively, NHL Holdings could guarantee borrowings made by the Company with
such a pledge. Moreover, following the reorganization, NHL Holdings may create
an intermediate holding company between itself and the Company which could
borrow funds from financial institutions or in the securities markets,
similarly providing the foregoing advantages and freeing NHL Holdings from any
constraints that would be imposed as a condition to such borrowings. This
holding company structure also would provide more flexibility in that companies
could be acquired directly by NHL Holdings rather than through the Company, and
thereby remain independent of the Company's present operations and free from
any constraints on the Company imposed by credit agreements or otherwise.

AMENDMENT OR TERMINATION

The Company, NHL Holdings and NHL Acquisition, by action of their
respective Boards of Directors, may amend, modify or supplement the Plan of
Merger at any time before or after its approval by the stockholders of the
Company. After such approval, no such amendment, modification or supplement may
be made or effected that by law requires further approval by such stockholders
without the further approval of such stockholders.
7

The Plan of Merger provides that it may be terminated, and the
reorganization abandoned, at any time, whether before or after stockholder
approval of the Plan of Merger, by action of the Board of Directors of NHL
Holdings.

FEDERAL INCOME TAX CONSEQUENCES

The Company and NHL Holdings have been advised by their counsel,
Cravath, Swaine & Moore, New York, New York, that, in their opinion, for United
States federal income tax purposes, assuming that the reorganization will take
place as described in the Plan of Merger:

(i) No gain or loss will be recognized by the Company, NHL
Holdings or the stockholders of the Company upon the conversion or exchange of
the Company's common stock for NHL Holdings' common stock pursuant to the Plan
of Merger.

(ii) The tax basis of NHL Holdings' common stock received by
the Company's stockholders pursuant to the Plan of Merger will be the same as
their tax basis in the Company's common stock converted or exchanged.

(iii) The holding period of NHL Holdings' common stock to be
received by the Company's stockholders in connection with the Plan of Merger
will include the period during which the Company's common stock being converted
or exchanged was held, provided that the Company's common stock is held as a
capital asset in the hands of the stockholder at the effective time.

Although it is not anticipated that state or local income tax
consequences to stockholders will vary substantially from the federal income
tax consequences described above, stockholders of the Company are urged to
consult with their own tax advisors with respect thereto, as well as with
respect to any foreign taxes applicable to foreign stockholders.

NEW YORK STOCK EXCHANGE LISTING

The common stock of NHL Holdings has been approved for listing on the
NYSE, subject to official notice of issuance, under the same symbol ("NH") as
the Company's common stock. At the effective time of the reorganization, the
Company's common stock will cease to be listed on the NYSE. As a practical
matter, current owners of the Company's common stock will continue to be able
to sell their shares of the Company's common stock (or, after the effective
time, NHL Holdings' common stock) on the NYSE without interruption.

STOCK OPTION PLANS

If the reorganization is consummated, the Company's stock option plans
(including, if approved, the 1994 Option Plan) will be amended if necessary to
cover any eligible employees of NHL Holdings and its subsidiaries and to
provide that NHL Holdings' common stock will thereafter be issued by NHL
Holdings upon exercise of any options issued thereunder. Stockholder approval
of the reorganization constitutes approval of NHL's assumption of the
obligations of the Company under the stock option plans. The retirement and
other employee benefit plans of the Company will be similarly revised or
amended, as necessary.

REGULATORY APPROVALS

The consummation of the transactions described herein do not require
the approval of, or compliance with rules promulgated by, any federal or state
regulatory authority.

APPRAISAL RIGHTS

Pursuant to Section 262 of the Delaware General Corporation Law, the
stockholders of the Company will not have appraisal rights with regard to the
reorganization.

DIVIDENDS

Quarterly dividends on NHL Holdings' common stock are expected to be
paid on approximately the same terms and dates as currently applicable to
dividends on the Company's common stock. Future dividends on NHL Holdings'
common stock will depend upon the earnings, financial conditions and other
factors of NHL Holdings and its subsidiaries. The quarterly dividend most
recently declared by the Board of Directors of the Company was $0.08 per share,
payable on April 26, 1994 to holders of record of the Company's common stock on
April 5, 1994.

DIRECTORS AND EXECUTIVE OFFICERS

The Board of Directors of NHL Holdings, upon the effectiveness of the
reorganization, is to consist of those persons who, at the effective time of
the reorganization, are serving as directors of the Company, each to have the
term of office for which he or she was elected or appointed. NHL Holdings'
executive officers are now, and upon the effectiveness of the reorganization
are expected to be, the same as those persons who are presently employed as
executive officers of the Company.

CERTIFICATE OF INCORPORATION AND BY-LAWS OF NHL HOLDINGS

The Certificate of Incorporation and By-laws of NHL Holdings have been
prepared in accordance with the Delaware General Corporation Law and do not
differ in any material respect from the Restated Certificate of Incorporation
and By-laws of the Company. The Company's certificate of incorporation and By-
laws are included in the materials incorporated by reference in this Proxy
Statement/Prospectus and NHL Holdings' certificate of incorporation and By-laws
are included as exhibits to the Registration Statement of which this Proxy
Statement/Prospectus forms a part.

As of the effective time of the reorganization, Article FOURTH of the
Company's certificate of incorporation will be amended so that the authorized
number of shares which the Company may issue will be one thousand (1,000).

DESCRIPTION OF NHL HOLDINGS' CAPITAL STOCK

There are no material differences between the terms of the capital
stock of NHL Holdings and the capital stock of the Company. After the effective
time of the reorganization, the number of shares of NHL Holdings' common stock
outstanding will equal the number of shares of the Company's common stock
outstanding immediately prior to the effective time. Following the effective
time, NHL Holdings will also have the same number of shares of preferred stock
authorized (with none being outstanding) as will be the case with respect to
the Company immediately prior to the effective time.

All shares of NHL Holdings' common stock will participate equally with
respect to dividends and rank equally upon liquidation, subject to the rights
of holders of any prior ranking stock which may be subsequently authorized and
issued. In the event of liquidation, dissolution or winding up of NHL Holdings,
the owners of its common stock are entitled to receive pro rata the assets and
funds of NHL Holdings remaining after satisfaction of all creditors of NHL
Holdings and payment of all amounts to which owners of prior ranking stock, if
any, then outstanding may be entitled. Each share of NHL Holdings' common stock
is entitled to one vote.

The Transfer Agent and Registrar for NHL Holdings' common stock will be
the same as is presently serving in such capacity for the Company's common
stock: American Stock Transfer & Trust Co.

COMPENSATION PLANS AND ARRANGEMENTS

The Company has an employment agreement with Mr. Maher which provides
for his employment as President and Chief Executive Officer of the Company
through December 31, 1995 at an annual salary of $1,000,000 and an annual year-
end retention bonus of $500,000. In addition, Mr. Maher is eligible to receive
an additional bonus as may be awarded at the sole discretion of the Board of
Directors or the Employee Benefits Committee. If the employment agreement with
Mr. Maher is terminated by the Company without cause or by Mr. Maher for
certain specified reasons (for example, assignment of duties inconsistent with
his position as Chief Executive Officer, reduction in base salary or bonus, or
relocation) or upon a Change of Control of the Company, the Company will be
required to pay Mr. Maher in a lump sum of $3,000,000. For this purpose, a
"Change of Control" is deemed to occur if Mr. Perelman ceases beneficially to
own 5% or more of the combined voting power of the Company's then outstanding
securities.

The Company has an amended employment agreement with Mr. Flaugh which
provides for Mr. Flaugh to be employed through December 31, 1995 at a base
salary of $500,000 per annum, an annual year-end retention bonus equal to 50%
of base salary and discretionary bonuses each year to be determined in light of
his and the Company's performance, with a one year period of non-competition
following termination of employment. Mr. Flaugh is entitled to receive a
$150,000 lump sum payment in December 1994 if he is then employed by the
Company.

The Company has amended employment agreements with Mr. Brodnik, Dr.
Statland and Dr. Slaunwhite which provide for them to be employed through
December 31, 1996, December 31, 1995 and December 31, 1996, respectively, at a
base salary of $325,000 per annum, an annual year-end retention bonus equal to
50% of base salary and discretionary bonuses each year to be determined in
light of each individual's and the Company's performance, with a one year
period of non-competition following termination of employment. Pursuant to the
employment agreements, Mr. Brodnik, Dr. Statland and Dr. Slaunwhite are
entitled to receive lump sum payments of $100,000, $90,000 and $120,000,
respectively, in December 1994, in each case only if the executive is then
employed by the Company. In addition, Dr. Statland is employed by the Company
as Chairman of the Company's Board of Scientific Advisors at a base salary of
$132,500 per annum. The Company has an employment agreement with Michael L.
Jeub which provides for Mr. Jeub to be employed as Executive Vice President and
Chief Financial Officer of the Company through June 30, 1995 at a base salary
of $250,000 per annum through the end of the term and an annual guaranteed
retention bonus equal to 50% of the base salary.

RETIREMENT BENEFITS AND SAVINGS PLAN.

The following table sets forth the estimated annual retirement benefits

- ----------
(1) Highest consecutive five year average base compensation during final ten years. Compensation considered for this
five year average is reflected in the Summary Compensation Table under the heading "salary." Under the Equalization
Plan, a maximum of $300,000 final average compensation is considered for benefit calculation. No bonuses are considered.

(2) Under the plans, the normal form of benefit for an unmarried participant is a life annuity with a guaranteed minimum payment
of ten years. Payments in other optional forms, including the 50% joint and survivor normal form for married participants,
are actuarially equivalent to the normal form for an unmarried participant. The above table is determined with regard to a
life only form of payment; thus, payment using a ten year guarantee would produce a lower annual benefit.

The Retirement Plan, which is intended to qualify under Section 401 of
the Internal Revenue Code of 1986, as amended (the "Code"), is a defined
benefit pension plan designed to provide an employee having 30 years of
credited service with an annuity equal to 52% of final average compensation
less 50% of estimated individual Social Security benefits. Credited service is
defined generally as all periods of employment with National Health
Laboratories Incorporated, a participating subsidiary or with Revlon prior to
1992, after attainment of age 21 and completion of one year of service. Final
average compensation is defined as average annual base salary during the five
consecutive calendar years in which base salary was highest out of the last ten
years prior to normal retirement age or earlier termination. The Employment
Retirement Income Security Act of 1974, as amended, places certain maximum
limitations upon the annual benefit payable under all qualified plans of an
employer to any one individual. Such limitation for defined benefit pension
plans was $115,641 for 1993 (except to the extent a larger benefit had accrued
as of December 31, 1982) and $118,800 for 1994, and will be subject to cost of
living adjustments for future years. In addition, the Tax Reform Act of 1986
limits the amount of compensation that can be considered in determining the
level of benefits under qualified plans. The applicable limit is adjusted
annually; for 1993 the limit was $235,840 and for 1994 is reduced to $150,000
due to provisions of the Omnibus Budget Reconciliation Act of 1993. The Company
believes that, with respect to certain employees, annual retirement benefits
computed in accordance with the Retirement Plan's benefit formula may be
greater than such qualified plan limitation. The Company's non-qualified,
unfunded, Equalization Plan is designed to provide for the payment of the
difference, if any, between the
15

amount of such maximum limitation and the annual benefit that would be payable
under the Retirement Plan but for such limitation.

As of December 31,1993, credited years of service under the retirement
plans for the following individuals are for Mr. Maher-none, Mr. Flaugh-21
years, Dr. Slaunwhite-11 years, Dr. Statland-1 year and Mr. Brodnik-20 years.

EMPLOYEE BENEFITS COMMITTEE REPORT ON EXECUTIVE COMPENSATION

The Employee Benefits Committee of the Board of Directors (the
"Committee") is comprised of Saul J. Farber, M.D., Howard Gittis, David J.
Mahoney, Linda Gosden Robinson and Samuel O. Thier, M.D. The Committee's duties
include determination of the Company's compensation and benefit policies and
practices for executive officers and key managerial employees. The Committee
also considers and awards options to purchase shares of the Company's common
stock pursuant to the Company's 1988 Stock Option Plan and the 1994 Option
Plan, subject to stockholder approval. In accordance with rules established by
the Commission, the Company is required to provide certain data and information
in regard to the compensation provided to the Company's Chief Executive Officer
and the four other most highly compensated executive officers. The Committee
has prepared the following report for inclusion in this Proxy
Statement/Prospectus.

Compensation Policies. The Company's current compensation arrangements
for senior executives are significantly affected by the Company's long history
as a private company until the 1988 initial public offering, after which an
Employee Benefits Committee was established. The overall compensation program
for officers historically emphasized a strong base salary position in relation
to competitive practice and a competitive annual bonus opportunity dependent
upon the operating income performance of the corporation. In contrast to the
Company's highly competitive cash compensation policy, the Company did not
offer long-term incentive opportunities as an executive compensation element
until 1989 when the first stock option awards were made. The Committee
understands that the combination of strongly competitive cash compensation and
modest use of long-term incentives is typical of private companies with
professional management leadership and this historical approach continued to
influence the Company's programs as a public company from 1989 into 1992. Late
in 1992, with the appointment of James R. Maher as President and Chief
Executive Officer, the Company's compensation philosophy changed to make a
greater portion of executive compensation dependent on the Company's long-term
stock performance.

The option grant and stock award approved in December 1992 by the
Committee for Mr. Maher reflected a shift in the Company's compensation
philosophy. This was followed early in 1993 by an award of stock options to the
next four most highly compensated officers. In 1993, the Committee also granted
options in varying amounts to 133 other senior and mid-level managers. The
option awards at all levels of management is a part of the Committee's desire
to make a growing and more significant portion of senior executive compensation
directly dependent on the Company's long term share price appreciation. The
number of options granted in 1993 to each of the four senior executives named
in the cash compensation table were determined considering the Corporation's
relatively low historical option grants, the Committee's desire to make a
greater proportion of the senior executives' compensation equity-based, an
analysis of the potential value of the options over the term of the option and
a review of option grants at the peer companies listed in the stock performance
graph.

In 1992, after consultations with Mr. Maher, the Committee decided to
raise the senior executive base salary levels and to restructure the annual
bonus opportunity as the combination of a cash year-end retention bonus equal
to 50% of base salary and a performance bonus opportunity. The general effect
of these salary and bonus actions was to set the overall cash compensation
opportunity for senior executives at or below 1992 levels, while strengthening
the retentive elements of the compensation package. When these arrangements
were established it was anticipated that the performance bonus would be based
on achieving operating income growth and the contribution of each senior
executive as evaluated by the Chief Executive Officer and approved by the
Committee.
16

The Committee believes that each of the four most highly compensated
senior executives of the Company have demonstrated superior performance in 1993
during a difficult period for the Company in the aftermath of the government
settlement and the general uncertainty in the medical services marketplace.
Notwithstanding such performance, however, given industry conditions and the
effects of the changes in the industry on the Company's results, the Committee
believes that it would not be appropriate to award any discretionary bonus
above the year end retention bonus nor to increase any compensation levels for
senior executives at this time.

Compensation of Chief Executive Officer. The compensation arrangement
with the Company's President and Chief Executive Officer was entered into in
December 1992. At that time, the Committee considered the salary and incentive
pay levels at public companies whose financial characteristics and market
capitalization are similar to the Company and whose workforce skills
requirements and customer base are similar. The Committee also considered the
Company's circumstances and special leadership challenges in the aftermath of
the settlement with the federal government. In the Committee's judgment, these
circumstances required stable new direction at the chief executive officer
level to help ensure sustained quality of the Company's services and continued
employee commitment to the Company's objectives.

Based on these considerations and the Company's strategic direction for
executive compensation, it was determined to provide a cash compensation
arrangement for the Chief Executive consisting of an annual salary of $1
million, a year-end retention bonus of $500,000 for each year of the contract
term and an annual discretionary performance bonus opportunity. The Committee
also determined that it was important to structure the Chief Executive
Officer's total compensation package to reflect the policy of creating strong
financial incentives for executive officers to achieve a high level of long
term shareholder return. Accordingly, the Chief Executive Officer was awarded
100,000 shares of the Company's common stock and granted options to purchase
300,000 shares at the then fair market value of the shares, which options vest
during the term of the three year contract. The Committee views the common
stock and stock option awards as the primary means by which the Chief Executive
Officer would be rewarded for the Company's business success and believes it is
important for the Chief Executive Officer to maintain and increase his equity
interest in the Company. The annual discretionary bonus opportunity was adopted
as a special recognition vehicle appropriate for years in which the Company
achieves superior performance as measured against industry results for growth
in operating income and revenues. The Committee decided that with respect to
1993, Mr. Maher, like the other senior executives, would receive no
discretionary cash bonus in excess of his year end retention bonus.

Limit on Deductibility of Compensation. The Omnibus Budget
Reconciliation Act of 1993 ("OBRA") limits the tax deductibility of
compensation paid to the chief executive officer and each of the four highest
paid employees of public companies to $1 million for fiscal years beginning on
or after January 1, 1994. Certain types of compensation, however, including
qualifying performance-based compensation and compensation arrangements entered
into prior to February 17, 1993 are excluded from the limitation. The Company's
general policy is to preserve the tax deductibility of compensation paid to its
executive officers. OBRA recognizes stock option plans as performance-based if
such plans meet certain requirements. The Company's 1994 Option Plan that will
be voted upon at the annual meeting of stockholders is structured to meet the
requirements of OBRA. In future years, the Compensation Committee will consider
taking such steps as it deems necessary to qualify compensation so as not to be
subject to the limit on deductibility.

COMMON STOCK PERFORMANCE

The Commission requires a five-year comparison of stock performance for
the Company with stock performance of appropriate similar companies. The
Company's common stock is traded on the NYSE. Set forth below is a line graph
comparing the yearly percentage change in the cumulative total shareholder
return on the Company's common stock and the cumulative total return on the S&P
Composite-500 Stock Index and a peer group of companies. The peer group of
companies includes eighteen companies selected by the Company. Two of these are
medical service laboratories like the Company - Nichols Institute and Unilab
Corporation. (Other direct competitors of the Company are subsidiaries of much
larger diversified corporations which were not believed appropriate to be peer
companies.) The remaining fifteen companies are all publicly traded medical
service and medical supply companies with sales ranging from $400 million to
$1.6 billion - Continental Medical Systems, Inc., Universal Health Services,
Inc., Charter Medical Corporation, Columbia Hospital Corporation, Allergan,
Inc., C. R. Bard, Inc., Pall Corporation, Thermo Electron Corporation, United
States Surgical Corporation, Bausch & Lomb Incorporated, Millipore Corporation,
Amsco International, Inc., Beckman Instruments, Inc., FHP International
Corporation and Fisher Scientific International, Inc. (Damon Corporation which
had been included in the Company's peer group in the 1993 Proxy Statement is no
longer a public company and is therefore not included in the peer group.)

EMPLOYEE BENEFITS COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

The members of the Employee Benefits Committee are Saul J. Farber,
M.D., Howard Gittis, David J. Mahoney, Linda Gosden Robinson and Samuel O.
Thier, M.D. No member of the Employee Benefits Committee is an officer or
employee of the Company.

Certain Director Relationships. Robinson, Lake, Lerer &
Montgomery/Sawyer Miller Group, the corporate communications firm of which Ms.
Robinson is President and Chief Executive Officer performs corporate
communications services for MacAndrews & Forbes and its affiliates, including
the Company. The amount of compensation paid to Robinson, Lake for services to
the Company in 1993 was $180,705. On September 17, 1993, the Company purchased
66% of the common stock of a newly-formed corporation, Health Partners, Inc.
("Health Partners"), which was formed to make acquisitions in the health care
industry. Ms. Robinson purchased 2% of the common stock of Health Partners and,
in connection with such purchase, entered into a consulting agreement with
Health Partners. Ms. Robinson currently receives no cash compensation for her
consulting services to Health Partners. A portion of Ms. Robinson's common
stock is held in escrow by Health Partners subject to vesting during the term
of her consulting agreement. In January 1993, the Company entered into an
agreement with Macalester Partners Ltd. ("Macalester"), a corporation in which
Ms. Robinson is a stockholder, pursuant to which Macalester will provide
consulting services to the Company in identifying investment opportunities for
the Company in the health care sector. Ms. Robinson received no compensation
from Macalester during 1993. The agreement with Macalester was terminated as of
September 7, 1993 in connection with the formation of Health Partners. For its
services, the Company paid Macalester $525,000 in 1993. Ms. Robinson is the
wife of a consultant to MacAndrews & Forbes who receives $250,000 per annum for
his services to MacAndrews & Forbes.

Ms. Jordan is the wife of a director of a subsidiary of MacAndrews &
Forbes who is a partner in a law firm that has on a regular basis in the past
provided services and that continues to provide services to MacAndrews & Forbes
and its affiliates, including the Company. The amount of fees and disbursements
charged to the Company for services performed by such firm in 1993 was
approximately $31,000.

Dr. Farber is on the Company's Scientific Advisory board and is paid
$15,000 per annum for such services.

RATIFICATION OF INDEPENDENT AUDITORS

The Audit Committee and the Board of Directors has selected, subject to
ratification by the stockholders, KPMG Peat Marwick to audit the accounts of
the Company for the fiscal year ending December 31, 1994. The ratification of
the selection of KPMG Peat Marwick will require the affirmative vote of the
holders of a majority of the outstanding shares of common stock present in
person or represented by proxy at the annual meeting and entitled to vote.
Under applicable Delaware law, in determining whether the proposal has received
the requisite number of affirmative votes, abstentions and broker non-votes
will be counted and will have the same effect as a vote against the proposal.

KPMG Peat Marwick has audited the consolidated financial statements of
the Company for more than the past five years. For 1993, KPMG Peat Marwick's
audit fees totalled approximately $175,000. KPMG Peat Marwick

representatives will be present at the annual meeting with the opportunity to
make a statement if they desire to do so and will be available to respond to
appropriate questions.

THE COMPANY RECOMMENDS THAT STOCKHOLDERS VOTE FOR THE RATIFICATION OF
THE SELECTION OF KPMG PEAT MARWICK AS THE COMPANY'S INDEPENDENT AUDITORS.
1994 OPTION PLAN

The Company's Board proposes that the stockholders approve the 1994
Option Plan approved by the Employee Benefits Committee on February 10, 1994
and by the Company's Board on February 15, 1994, subject to the approval of the
Company's stockholders. The approval of the 1994 Option Plan requires the
affirmative vote of the holders of a majority of the outstanding shares of the
Company's common stock. Following the reorganization, NHL Holdings will assume
all obligations under the 1994 Option Plan. See "Proposed Reorganization-Stock
Option Plans".

The Company has heretofore granted options relating to all the 2.5
million shares which were available under its 1988 Stock Option Plan.

The following paragraphs summarize the principal features of the 1994
Option Plan. This summary is subject, in all respects, to the terms of the 1994
Option Plan. The Company will provide promptly, upon written request and
without charge, a copy of the full text of the 1994 Option Plan to each person
to whom a copy of this proxy statement is delivered. Requests should be
directed to: National Health Laboratories Incorporated, 4225 Executive Square,
Suite 800, La Jolla, California 92037, Attention: Stockholder Relations.

Subject to certain modifications required by changes in law and
regulation and except as otherwise described herein, the Company's 1994 Option
Plan is substantially identical to its 1988 Stock Option Plan. The 1994 Option
Plan will be administered by the Employee Benefits Committee appointed by the
Company's Board of Directors. During the ten-year period ending on the tenth
anniversary of the adoption of the 1994 Option Plan, the Employee Benefits
Committee will have authority, subject to the terms of the 1994 Option Plan, to
determine when and to whom to make grants under the plan, the number of shares
to be covered by the grants, the types and terms of options and SARs granted
and the exercise price of the shares of common stock covered by options and
SARs, and to prescribe, amend and rescind rules and regulations relating to the
1994 Option Plan.

The Company's Board of Directors may amend or terminate the 1994 Option
Plan at any time except that, unless approved (at a meeting held within 12
months before or after the date of such amendment) by a majority of the voting
shares of common stock of the Company, no such amendment may (i) increase the
maximum number of shares as to which options may be granted under the 1994
Option Plan, except for adjustments to reflect stock dividends or other
recapitalizations affecting the number or kind of outstanding shares, (ii)
change the requirements as to eligibility for participation in the 1994 Option
Plan or (iii) otherwise materially change the 1994 Option Plan.

Under the terms of the 1994 Option Plan, incentive stock options
("ISOs") within the meaning of Section 422 of the Internal Revenue Code of
1986, as amended (the "Code"), non-qualified stock options ("NQSOs"), and SARs
may be granted by the Employee Benefits Committee in its discretion to key
employees (including officers and directors who are employees) of the Company
and any of its affiliates, except that ISOs may be granted only to employees of
the Company and its parent company and any subsidiary corporation. Due to the
provision of the plan which permits awards in the discretion of the Employee
Benefits Committee, it is not possible to determine how many employees of the
Company and its affiliates may be eligible for grants of options and SARs. The
1994 Option Plan generally provides that no individual employee may be granted
options or SARs representing an aggregate of more than 750,000 shares of the
Company's common stock. The aggregate number of shares of common stock as to
which options and SARs may be granted under the 1994 Option Plan will not
exceed 3,000,000.
22

The aggregate fair market value, as defined in the 1994 Option Plan and
determined as of the date of grant of an ISO, of common stock with respect to
which ISOs granted under the 1994 Option Plan and all other option plans of the
Company and its parent company first become exercisable during any calendar
year may not exceed $100,000 for any employee. The foregoing limitation does
not apply to NQSOs.

Initially, each ISO will be exercisable over a period, determined by
the Employee Benefits Committee in its discretion, but not to exceed ten years
from the date of grant, as required by the Code. In addition, in the case of an
ISO granted to an individual who, at the time such ISO is granted, owns shares
possessing more than ten percent of the total combined voting power of all
classes of stock of the Company (a "Ten Percent Stockholder"), the exercise
period for an ISO may not exceed five years from the date of grant. In the case
of NQSOs, the exercise period will in all cases be determined by the Employee
Benefits Committee. Options may be exercised during the option period at such
times, in such amount, in accordance with such terms and conditions, and
subject to such restrictions, as are set forth in the option agreement
evidencing the grant of such options.

The exercise price of an ISO or a NQSO ("Option Price") may not be less
than one hundred percent (100%) of the fair market value of the shares of the
common stock on the date of grant, except that, in the case of an ISO granted
to a Ten Percent Stockholder, such Option Price may not be less than one
hundred ten percent (110%) of such fair market value. The Option Price of, and
the number of shares covered by, each option will not change during the life of
the option, except for adjustments to reflect stock dividends, splits, other
recapitalizations or reclassifications or changes affecting the number or kind
of outstanding shares.

The shares of common stock purchased upon the exercise of an option are
to be paid for in cash (including cash that may be received from the Company at
the time of exercise as additional compensation) or through the delivery of
other shares of the common stock with a value equal to the total Option Price
or in a combination of cash and such shares, or with money lent by the Company
to the optionee in compliance with applicable law and on terms and conditions
to be determined by the Company.

No option may be transferred by an optionee during his lifetime. If the
employment of an optionee terminates for any reason (other than by reason of
death, disability or retirement) the optionee may, within the three-month
period following such termination, exercise such options to the extent he was
entitled to exercise such options at the date of termination. If an optionee
dies while employed (or within three months after termination of employment) or
terminates employment by reason of disability or retirement, all previously
granted options (whether or not then exercisable), may, unless earlier
terminated in accordance with their terms, be exercised by the person or
persons to whom the optionee's rights pass within one year after the optionee's
death or by the optionee within one year after the optionee's disability or
retirement.

The Employee Benefits Committee may also grant SARs either alone ("Free
Standing Rights") or in conjunction with all or part of an option ("Related
Rights"). Upon the exercise of a SAR, a holder is entitled, without payment to
the Company, to receive cash, unrestricted shares of common stock or any
combination thereof, as determined by the Employee Benefits Committee, in an
amount equal to the excess of the fair market value of one share of common
stock over the exercise price per share specified in the related option (or in
the case of a Free Standing Right, the price per share specified in such
right), multiplied by the number of shares in respect of which the SAR is
exercised.

The Company is required to charge earnings at the close of each
accounting period during which the SARs are outstanding. The charge will be
equal to the amount by which the fair market value of the shares of stock
subject to the SARs exceeds the price for which the SARs may be exercised, less
the tax deduction to which the Company may be entitled if the SARs were
exercised and less any portion of such amount charged to earnings in prior
periods. In the event that the stock subject to the SARs has depreciated in
market value since the last accounting period, there will be a credit to
earnings.
23

Under the 1994 Option Plan, the exercisability of options and Related
Rights will be accelerated upon a Change in Control of the Company (as defined
in the 1994 Option Plan). The 1998 Stock Option Plan did not have such a change
in control provision. (The proposed reorganization discussed herein will not
constitute such a Change in Control of the Company.) If the exercisability of
an option or SAR is so accelerated, payments made with respect to such option
or SAR may constitute an "excess parachute payment" that is not deductible by
the Company in whole or in part under Section 280G of the Code. Such
acceleration may also subject the holder of such option or SAR to a 20% federal
excise tax under Section 4999 of the Code on all or a portion of the value
conferred on such holder by reason of the Change in Control. Option agreements
may provide that the Company will reimburse such holder for the full amount of
any such excise tax imposed.

THE COMPANY RECOMMENDS THAT STOCKHOLDERS VOTE FOR THE APPROVAL OF THE
ADOPTION OF THE 1994 OPTION PLAN.

SECURITY OWNERSHIP OF CERTAIN BENEFICIAL HOLDERS

The following table sets forth as of April 25, 1994, the total number
of shares of common stock beneficially owned, and the percent so owned, by each
director of the Company who is a beneficial owner of any shares of common
stock, by each person known to the Company to be the beneficial owner of more
than 5% of the outstanding common stock, by the officers named in the summary
compensation table and by all directors and officers as a group. The number of
shares owned are those "beneficially owned," as determined under the rules of
the Commission, and such information is not necessarily indicative of
beneficial ownership for any other purpose. Under such rules, beneficial
ownership includes any shares as to which a person has sole or shared voting
power or investment power and any shares of common stock which the person has
the right to acquire within 60 days through the exercise of any option, warrant
or right, through conversion of any security, or pursuant to the automatic
termination of power of attorney or revocation of trust, discretionary account
or similar arrangement.

CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

Tax Allocation Arrangement. The Company was included in the
consolidated federal income tax returns, and in certain state income tax
returns, of Mafco, M&F Holdings, Revlon Group Incorporated and Revlon Holdings
Inc., formerly known as Revlon Inc. As a result of the reduction of MacAndrews
& Forbes' ownership interest in the Company on May 7, 1991, the Company is no
longer a member of the Mafco consolidated tax group. For periods subsequent to
May 7, 1991, the Company files its own separate federal, state and local income
tax returns. Nevertheless, the Company will remain obligated to pay to M&F
Holdings (or other members of the consolidated group of which M&F Holdings is a
member) any income taxes the Company would have had to pay (in excess of those
which it has already paid) if it had filed separate income tax returns for
taxable periods beginning on or after January 1, 1985 (but computed without
regard to (i) the effect of timing differences (i.e., the liability or benefit
that otherwise could be deferred will be, instead, includible in the
determination of current taxable income) and (ii) any gain recognized on the
sale of any asset not in the ordinary course of business). In addition, despite
the reduction of MacAndrews & Forbes' indirect ownership of the Company, the
Company will continue to be subject under existing federal regulations to
several liability for the consolidated federal income taxes for any
consolidated return year in which it was a member of any consolidated group of
which
25

Mafco, M&F Holdings, Revlon Group or Revlon was the common parent. However,
Mafco, M&F Holdings, Revlon Group and Revlon have agreed to indemnify the
Company for any federal income tax liability (or any similar state or local
income tax liability) of Mafco, M&F Holdings, Revlon Group, Revlon or any of
their subsidiaries (other than that which is attributable to the Company or any
of its subsidiaries) that the Company could be required to pay.

Registration Rights Agreement. The Company entered into a Registration
Rights Agreement with Health Care pursuant to which the Company will be
obligated, upon the request of Health Care, to file registration statements
("demand registration statements") from time to time with the Commission
covering the sale of any shares of common stock owned by Health Care. Such
demand registration statements may also cover the resale from time to time of
any shares of common stock that Health Care may purchase in the open market at
a time when it is deemed to be an affiliate (as such term is defined under Rule
144 under the Securities Act of 1933, as amended), and certain securities
issued in connection with a combination of shares, recapitalization,
reclassification, merger or consolidation, or other pro rata distribution.
Health Care will also have the right to include such common stock and other
securities in any registration statement filed by the Company for the
underwritten public offering of shares of common stock (whether or not for the
Company's account), subject to certain reductions in the amount of such common
stock and securities if the managing underwriters of such offering determine
that the inclusion thereof would materially interfere with the offering. The
Company agreed not to effect any public or private sale, distribution or
purchase of any of its securities which are the same as or similar to the
securities covered by any demand registration statement during the 15-day
period prior to, and during the 45-day period beginning on, the closing date of
each underwritten offering under such registration statement and Health Care
agreed to a similar restriction with respect to underwritten offerings by the
Company. Health Care's rights under the Registration Rights Agreement are
transferable.

EXHIBIT A

CONFORMED COPY

AGREEMENT AND PLAN OF MERGER dated as of April 15, 1994, among
NATIONAL HEALTH LABORATORIES HOLDINGS INC., a Delaware corporation ("Parent"),
NHL SUB ACQUISITION CORP., a Delaware corporation ("Sub") and a wholly owned

corporation (the "Company").

WHEREAS the respective Boards of Directors of Parent, Sub and
the Company have approved the merger of Sub into the Company (the "Merger"),
upon the terms and subject to the conditions set forth in this Agreement,
whereby each issued and outstanding share of common stock, par value $.01 per
share, of the Company ("Company Common Stock"), other than shares owned
directly or indirectly by Parent or the Company, will be converted into the
right to receive common stock, par value $.01 per share, of Parent ("Parent
Common Stock");

WHEREAS the Merger requires the approval of the holders of a
majority of the outstanding shares of the Company Common Stock entitled to vote
thereon at the meeting of holders of Company Common Stock to be called therefor
(the "Company Stockholder Approval"); and

WHEREAS, for Federal income tax purposes, it is intended that
the Merger shall qualify as a reorganization under the provisions of Section
368(a) of the Internal Revenue Code of 1986, as amended (the "Code");

NOW, THEREFORE, the parties agree as follows:

ARTICLE I

The Merger

SECTION 1.01. The Merger. Upon the terms and subject to the
conditions set forth in this Agreement, and in accordance with the Delaware
General Corporation Law (the "DGCL"), Sub shall be merged with and into the
Company at the Effective Time of the Merger (as defined in Section 1.03).
Following the Effective Time of the Merger, the separate corporate existence of
Sub shall cease and the Company shall continue as the surviving corporation
(the "Surviving Corporation") and shall succeed to and assume all the rights
and obligations of Sub in accordance with the DGCL.

SECTION 1.02. Closing. The closing of the Merger (the
"Closing") will take place at 10:00 a.m. on a date to be specified by the
parties (the "Closing Date"), which shall be no later than the second business
day after satisfaction of the conditions set forth in Section 4.01, at the

SECTION 1.03. Effective Time. Subject to the provisions of
this Agreement, as soon as practicable following the satisfaction or waiver of
the conditions set forth in Section 4.01, the parties shall file a certificate
of merger or other appropriate documents (in any such case, the "Certificate of

shall make all other filings or recordings required under the DGCL. The Merger
shall become effective at such time as the Certificate of Merger is duly filed
with the Delaware Secretary of State, or at such other time as Sub and the
Company shall agree should be specified in the Certificate of Merger (the time
the Merger becomes effective being hereinafter referred to as the "Effective
Time of the Merger").

SECTION 1.04. Effects of the Merger. The Merger shall have
the effects set forth in Section 259 of the DGCL.

SECTION 1.05. Certificate of Incorporation and By-laws. (a)
The certificate of incorporation of the Company, as in effect immediately prior
to the Effective Time of the Merger, shall be amended as of the Effective Time
of the Merger so that Article FOURTH of such certificate of incorporation reads
in its entirety as follows: "The total number of shares of stock which the
Corporation shall have authority to issue is one thousand (1,000) shares of
Common Stock each having a par value of $1.00 per share." and, as so amended,
such certificate of incorporation shall be the certificate of incorporation of
the Surviving Corporation until thereafter changed or amended as provided
therein or by applicable law.

(b) The by-laws of the Company as in effect at the Effective
Time of the Merger shall be the by-laws of the Surviving Corporation until
thereafter changed or amended as provided therein or by applicable law.

SECTION 1.06. Directors. The directors of the Company at the
Effective Time of the Merger shall be the directors of the Surviving
Corporation, until the earlier of their resignation or removal or until their
respective successors are duly elected and qualified, as the case may be.

ARTICLE II

Effect of the Merger on the Capital Stock of the
Constituent Corporations; Exchange of Certificates

SECTION 2.01. Effect on Capital Stock. As of the Effective
Time of the Merger, by virtue of the Merger and without any action on the part
of the holder of any shares of Company Common Stock or any shares of capital
stock of Sub:

(a) Capital Stock of Sub. Each issued and outstanding share
of capital stock of Sub shall be converted into and become one fully paid and
nonassessable share of Common Stock, par value $.01 per share, of the Surviving
Corporation.

(b) Cancellation of Treasury Stock and Company-Owned Stock.
Each share of Company Common Stock and each share of Parent Common Stock that
is owned by the Company or its subsidiaries shall automatically be cancelled
and retired and shall cease to exist, and no Parent Common Stock or other
consideration shall be delivered in exchange for such Company Common Stock.

(c) Conversion of Company Common Stock. Each issued and
outstanding share of Company Common Stock (other than shares to be cancelled in
accordance with Section 2.01(b)) shall be converted into the right to receive
one fully paid and nonassessable share of Parent Common Stock. As of the
Effective Time of the Merger, all such shares of Company Common Stock shall no
longer be outstanding and shall automatically be cancelled and retired and
shall cease to exist, and each holder of a certificate representing any such
shares of Company Common Stock shall cease to have any rights with respect
thereto, except the right to receive the shares of Parent Common Stock to be
issued in consideration therefor upon surrender of such certificate in
accordance with Section 2.02, without interest.

SECTION 2.02. Exchange of Certificates. (a) Stock
Certificate. Following the Effective Time of the Merger, each holder of an
outstanding certificate or certificates theretofore representing shares of
Company Common Stock may, but shall not be required to, surrender the same to
Parent for cancellation or transfer, and each such holder or transferee will be
entitled to receive certificates representing the same number of shares of
Parent Common Stock as the shares of Company Common Stock previously
represented by the stock certificates surrendered. If any certificate
representing shares of Parent Common Stock is to be issued in a name other than
that in which the certificate theretofore representing Company Common Stock
surrendered is registered, it shall be a condition to such issuance that the
certificate surrendered shall be properly endorsed and otherwise in proper form
for transfer and that the person requesting such issuance shall either:

(i) pay Parent or its agents any taxes or other governmental
charges required by reason of the issuance of certificates representing shares
of Parent Common Stock in a name other than that of the registered holder of
the certificate so surrendered; or

(ii) establish to the satisfaction of Parent or its agents that
such taxes or governmental charges have been paid.

Until so surrendered or presented for transfer each outstanding certificate
which, prior to the Effective Time, represented Company Common Stock shall be
deemed and treated for all corporate purposes to represent the ownership of the
same number of shares of Parent Common Stock as though such surrender or
transfer and exchange had taken place.

(b) No Further Ownership Rights in Company Common Stock. All
shares of Parent Common Stock issued upon the surrender for exchange of
Certificates in accordance with the terms of this Article II shall be deemed to
have been issued (and paid) in full satisfaction of all rights pertaining to
the shares of Company Common Stock theretofore represented by such
Certificates, subject, however, to the Surviving Corporation's obligation to
pay any dividends or make any other distributions with a record date prior to
the Effective Time of the Merger which may have been declared or made by the
Company on such shares of Company Common Stock in accordance with the terms of
this Agreement or prior to the date of this Agreement and which remain unpaid
at the Effective Time of the Merger, and there shall be no further registration
of transfers on the stock transfer books of the Surviving Corporation of the
shares of Company Common Stock which were outstanding immediately prior to the
Effective Time of the Merger. If, after the Effective Time of the Merger,
Certificates are presented to the Surviving Corporation they shall be cancelled
and exchanged as provided in this Article II, except as otherwise provided by
law.

ARTICLE III

Additional Agreements

SECTION 3.01. Affiliates and Certain Stockholders. (a) Prior
to the Closing Date, the Company shall deliver to Parent a letter identifying
all persons who are, at the time the Merger is submitted for approval to the
stockholders of the Company, "affiliates" of the Company for purposes of Rule
145 under the Securities Act of 1933, as amended (the "Securities Act"). The
Company shall use its best efforts to cause each such person to deliver to
Parent on or prior to the Closing Date a written agreement substantially in the
form attached as Schedule A hereto.

(b) The Company shall deliver to Parent on the date of the
proxy statement relating to the Company Stockholder Approval (such proxy
statement, as amended or supplemented from time to time, the "Proxy Statement")
and on the Closing Date letters, in each case dated as of such respective dates
and identifying all persons who are, as of such respective dates, beneficial
owners of five percent or more of the Company Common Stock. The Company shall
use its best efforts to cause each such person to deliver to counsel to Parent
and to the Company on the date of the Proxy Statement and on the Closing Date
written agreements, in each case dated as of such respective dates and
substantially in the form attached as Schedule B hereto.
ARTICLE IV

Conditions Precedent

SECTION 4.01. Conditions to Each Party's Obligation To Effect
the Merger. The respective obligation of each party to effect the Merger is
subject to the satisfaction or waiver on or prior to the Closing Date of the
following conditions:

(a) Stockholder Approval. The Company Stockholder Approval
shall have been obtained.

(b) Form S-4. The registration statement on Form S-4 to be
filed with the Securities and Exchange Commission by Parent in connection with
the issuance of Parent Common Stock in the Merger shall have become effective
under the Securities Act and shall not be the subject of any stop order or
proceedings seeking a stop order.

Cravath, Swaine & Moore, counsel to the Company, on the date of the Proxy

representations of Company provided to such counsel, dated as of such
respective dates and stating that the Merger will be treated for Federal income
tax purposes as a reorganization within the meaning of Section 368(a) of the
Code and that Parent, Sub and the Company will each be a party to that
reorganization within the meaning of Section 368(b) of the Code.

approval by the stockholders of the Company of matters presented in connection
with the Merger, by Parent.

termination of this Agreement as provided in Section 5.01, this Agreement shall

of the Merger, the parties may waive compliance by the other parties with any
of the agreements or conditions contained in this Agreement. Any agreement on
the part of a party to any such waiver shall be valid only if set forth in an
instrument in writing signed on behalf of such party. The failure of any party
to this Agreement to assert any of its rights under this Agreement or otherwise
shall not constitute a waiver of such rights.

SECTION 5.05. Procedure for Termination, Amendment, Extension
or Waiver. A termination of this Agreement pursuant to Section 5.01, an
amendment of this Agreement pursuant to Section 5.03 or a waiver pursuant to
Section 5.04 shall, in order to be effective, require in the case of Parent,
Sub or the Company, action by its Board of Directors or the duly authorized
designee of its Board of Directors.

SCHEDULE A
Form of Company Affiliate Letter
Gentlemen:

The undersigned, a holder of shares of Common Stock, par value
$.01 per share ("Company Stock"), of National Health Laboratories Incorporated,
a Delaware corporation (the "Company"), is entitled to receive in connection
with the merger (the "Merger") of the Company with NHL Sub Acquisition Corp., a
Delaware corporation, securities (the "Parent Securities") of National Health
Laboratories Holdings Inc., a Delaware corporation ("Parent"). The undersigned
acknowledges that the undersigned may be deemed an "affiliate" of the Company
within the meaning of Rule 145 ("Rule 145") promulgated under the Securities
Act of 1933, as amended (the "Securities Act"), although nothing contained
herein should be construed as an admission of such fact.

If in fact the undersigned were an affiliate under the
Securities Act, the undersigned's ability to sell, assign or transfer the
Parent Securities received by the undersigned in exchange for any shares of
Company Stock pursuant to the Merger may be restricted unless such transaction
is registered under the Securities Act or an exemption from such registration
is available. The undersigned understands that such exemptions are limited and
the undersigned has obtained or will obtain advice of counsel as to the nature
and conditions of such exemptions, including information with respect to the
applicability to the sale of such securities of Rules 144 and 145(d)
promulgated under the Securities Act.

The undersigned hereby represents to and covenants with the
Company that the undersigned will not sell, assign or transfer any of the
Parent Securities received by the undersigned in exchange for shares of Company
Stock pursuant to the Merger except (i) pursuant to an effective registration
statement under the Securities Act or (ii) in a transaction which, in the
opinion of independent counsel reasonably satisfactory to Parent (the
reasonable fees of which counsel will be paid by Parent) or as described in a
"no-action" or interpretive letter from the Staff of the Securities and
Exchange Commission (the "SEC"), is not required to be registered under the
Securities Act.
In the event of a sale or other disposition by the undersigned
of Parent Securities pursuant to Rule 145, the undersigned will supply Parent
with evidence of compliance with such Rule, in the form of a letter in the form
of Annex I hereto and the opinion of counsel or no-action letter referred to
above.

The undersigned acknowledges and agrees that appropriate
legends will be placed on certificates representing Parent Securities received
by the undersigned in the Merger or held by a transferee thereof, which legends
will be removed by delivery of substitute certificates upon receipt of an
opinion in form and substance reasonably satisfactory to Parent from
independent counsel reasonably satisfactory to Parent (the reasonable fees of
which counsel will be paid by Parent) to the effect that such legends are no
longer required for purposes of the Securities Act.

The undersigned acknowledges that (i) the undersigned has
carefully read this letter and understands the requirements hereof and the
limitations imposed upon the distribution, sale, transfer or other disposition
of Parent Securities and (ii) the receipt by Parent of this letter is an
inducement and a condition to Parent's obligations to consummate the Merger.
Very truly yours,
Dated:

ANNEX I
TO SCHEDULE A
(Name) (Date)
On , the undersigned sold the securities
("Securities") of National Health Laboratories Holdings Inc. ("Parent")
described below in the space provided for that purpose (the "Securities"). The
Securities were received by the undersigned in connection with the merger of
NHL Sub Acquisition Corp., a subsidiary of Parent, with and into National
Health Laboratories Incorporated.

Based upon the most recent report or statement filed by Parent
with the Securities and Exchange Commission, the Securities sold by the
undersigned were within the prescribed limitations set forth in paragraph (e)
of Rule 144 promulgated under the Securities Act of 1933, as amended (the
"Securities Act").

The undersigned hereby represents that the Securities were sold
in "brokers' transactions" within the meaning of Section 4(4) of the Securities
Act or in transactions directly with a "market maker" as that term is defined
in Section 3(a)(38) of the Securities Exchange Act of 1934, as amended. The
undersigned further represents that the undersigned has not solicited or
arranged for the solicitation of orders to buy the Securities, and that the
undersigned has not made any payment in connection with the offer or sale of
the Securities to any person other than to the broker who executed the order in
respect of such sale.
Very truly yours,

(Space to be provided for description of the Securities.)

PART II

INFORMATION NOT REQUIRED IN PROSPECTUS
Item 20. Indemnification of Directors and Officers

As authorized by Section 145 of the General Corporation Law of
Delaware (the "Delaware Corporation Law"), each director and officer of the
Registrant may be indemnified by the Registrant against expenses (including
attorney's fees, judgments, fines and amounts paid in settlement) actually and
reasonably incurred in connection with the defense or settlement of any
threatened, pending or completed legal proceedings in which he is involved by
reason of the fact that he is or was a director or officer of the Registrant if
he acted in good faith and in a manner that he reasonably believed to be in or
not opposed to the best interests of the Registrant, and, with respect to any
criminal action or proceeding, if he had no reasonable cause to believe that
his conduct was unlawful. If the legal proceeding, however, is by or in the
right of the Registrant, the director or officer may not be indemnified in
respect of any claim, issue or matter as to which he shall have been adjudged
to be liable for negligence or misconduct in the performance of his duty to the
Registrant unless a court determines otherwise.

Article Fifth of the Certificate of Incorporation of the
Registrant, a copy of which is filed as Exhibit 3.1 to this Registration
Statement, provides that no director of the Registrant shall be personally
liable to the Registrant or its stockholders for monetary damages for any
breach of his fiduciary duty as a director; provided, however, that such clause
shall not apply to any liability of a director (1) for any breach of his duty
of loyalty to the Registrant or its stockholders, (2) for acts or omissions
that are not in good faith or involve intentional misconduct or a knowing
violation of the law, (3) under Section 174 of the Delaware Corporation Law or
(4) for any transaction from which the director derived an improper personal
benefit. In addition, Article Sixth of the Certificate of Incorporation and
Article Seventh of the By-laws, a copy of which is filed as Exhibit 3.2 hereto,
authorize the Registrant to indemnify any person entitled to be indemnified
under law to the fullest extent permitted by law.

(b) Financial Statement Schedules: Not applicable.
Item 22. Undertakings

(a) As to Rule 415:

The undersigned registrant hereby undertakes:

(1) To file, during any period in which offers or sales are
being made of the securities registered hereby, a post-effective amendment to
this registration statement:

(i) to include any prospectus required by Section
10(a)(3) of the Securities Act of 1933, as amended;

(ii) to reflect in the prospectus any facts or events
arising after the effective date of this registration statement (or the most
recent post-effective amendment hereof) which, individually or in the
aggregate, represent a fundamental change in the information set forth in this
registration statement; and

(iii) to include any material information with respect
to the plan of distribution not previously disclosed in this registration
statement or any material change to such information in this registration
statement.

(2) That, for the purpose of determining any liability under
the Securities Act of 1933, as amended, each such post-effective amendment
shall be deemed to be a new registration statement relating to the securities
offered therein, and the offering of such securities at that time shall be
deemed to be the initial bona fide offering thereof.

(3) To remove from registration by means of a post-effective
amendment any of the securities being registered which remain unsold at the
termination of the offering.

(b) As to documents subsequently filed that are
incorporated by reference:

The undersigned registrant hereby undertakes that, for purposes
of determining any liability under the Securities Act of 1933, as amended, each
filing of the registrant's annual report pursuant to Section 13(a) or Section
15(d) of the Securities Exchange Act of 1934, as amended, that is incorporated
by reference in this registration statement shall be deemed to be a new
registration statement relating to the securities offered herein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

Insofar as indemnification for liabilities arising under the
Securities Act of 1933, as amended, may be permitted to directors, officers and
controlling persons of the registrant pursuant to the provisions described
under Item 15 above, or otherwise, the registrant has been advised that in the
opinion of the Securities and Exchange Commission such indemnification is
against public policy as expressed in the Securities Act of 1933, as amended,
and is, therefore, unenforceable. In the event that a claim for indemnification
against such liabilities (other than the payment by the registrant of expenses
incurred or paid by a director, officer or controlling person of the registrant
in the successful defense of any action, suit or proceeding) is asserted by
such director, officer or controlling person in connection with the securities
being registered, the registrant will, unless in the opinion of its counsel the
matter has been settled by controlling precedent, submit to a court of
appropriate jurisdiction the question whether such indemnification by it is
against public policy as expressed in the Securities Act of 1933, as amended,
and will be governed by the final adjudication of such issue.

II-2

(d) The undersigned registrant hereby undertakes:

(1) that prior to any public reoffering of the securities
registered hereunder through use of a prospectus which is a part of the
registration statement, by any person or party who is deemed to be an
underwriter within the meaning of Rule 145(c) under the Securities Act of 1933,
as amended, the issuer undertakes that such reoffering prospectus will contain
the information called for by the applicable registration form with respect to
reofferings by persons who may be deemed underwriters, in addition to the
information called for by the other items of the applicable form; and

(2) that every prospectus (i) that is filed pursuant to
paragraph (1) immediately preceding, or (ii) that purports to meet the
requirements of Section 10(a)(3) of the Securities Act of 1933, as amended, and
is used in connection with an offering of securities subject to Rule 415 under
the Securities Act of 1933, as amended, will be filed as a part of an amendment
to the registration statement and will not be used until such amendment is
effective, and that, for purposes of determining any liability under the
Securities Act of 1933, as amended, each such post-effective amendment shall be
deemed to be a new registration statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.

(e) The undersigned registrant hereby undertakes to respond to
requests for information that is incorporated by reference into the prospectus
pursuant to Items 4, 10(b), 11 or 13 of this Form, within one business day of
receipt of such request, and to send the incorporated documents by first class
mail or other equally prompt means. This includes information contained in
documents filed subsequent to the effective date of the registration statement
through the date of responding to the request.

(f) The undersigned registrant hereby undertakes to supply by
means of a post-effective amendment all information concerning a transaction,
and the company being acquired involved therein, that was not the subject of
and included in the registration statement when it became effective.
