   threatening diseases characterized by high chronic care costs. The current
   focus of United Therapeutics is the development of therapies to treat
   patients with pulmonary hypertension, a generally fatal disorder of the
   pulmonary arteries, and peripheral vascular disease, a limb-threatening
   disorder affecting millions of Americans. All of United Therapeutics'
   products are currently in clinical trial programs.

      United Therapeutics has four wholly owned subsidiaries: Lung Rx, Inc.,
   Unither Pharmaceuticals, Inc., Unither Telemedicine Services Corporation and

   not necessarily indicative of results for an entire year.

3.    INVESTMENTS

      Investments at September 30, 1999 consist of marketable debt securities
   that have remaining maturities of six months or less.

4.    NOTES PAYABLE

      In June 1999, United Therapeutics refinanced its note payable. The
   outstanding principal totaled approximately $315,000 and was paid in full
   from the proceeds of a new mortgage note payable. The new mortgage note
   payable was issued for $720,000 and is payable in monthly installments. This
   30-year adjustable rate note had an interest rate of 6.25 percent in effect
   at September 30, 1999 and is secured by the building and property owned by
   United Therapeutics located at 1110 Spring Street in Silver Spring, Maryland.

      In September 1999, United Therapeutics purchased a building adjacent to
   1110 Spring Street in Silver Spring, Maryland. The total cost of the building
   was approximately $1,544,000. United Therapeutics issued a mortgage note
   payable to finance this purchase. The mortgage note payable was

   issued for $1,078,000 and is payable in monthly installments. This 30-year
   adjustable rate note had an interest rate of 5.75 percent in effect at
   September 30, 1999 and is secured by a certificate of deposit and the
   building and property owned by United Therapeutics located at 1106 Spring
   Street in Silver Spring, Maryland.

5.    STOCKHOLDERS' EQUITY

      During the nine month period ended September 30, 1999, the following
   events and transactions impacted stockholders' equity:

      (a) Private Placements of Common Stock
      During the first quarter of 1999, United Therapeutics sold 111,370 shares
   of common stock at a price of $18.00 per share through private placements.
   Total proceeds from these private placements, net of offering expenses,
   approximated $2.0 million.

      (b) Issuance of Common Stock for License
      In March 1999, United Therapeutics issued 500,000 shares of common stock
   in exchange for an exclusive license agreement. The stock was valued at $9.0
   million ($18.00 per share) based on recent sales at $18.00 per share. The
   total of $9.0 million was expensed as research and development in the first
   quarter of 1999.

      (c) Reverse Stock Split
      In April 1999, United Therapeutics' Board of Directors approved a
   one-for-three reverse stock split of its outstanding common stock.
   Shareholders of United Therapeutics subsequently approved the reverse split
   and it was effected on June 11, 1999, prior to the public offering.
   Fractional shares were not issued and no consideration was given for
   fractional shares. Authorized shares and the par values of common and
   preferred stock were not affected by the reverse stock split, although at the
   same time United Therapeutics increased the total number of authorized shares
   of common stock to 100,000,000. All share and per share amounts in these
   notes, the accompanying financial statements and otherwise in this report on
   Form 10-Q have been retroactively adjusted to reflect the reverse stock split
   for all periods presented.

      (d) Initial Public Offering
      On June 17, 1999, United Therapeutics' initial public offering, which
   involved the sale of 4,500,000 shares of common stock at $12.00 per share,
   was declared effective by the SEC. United Therapeutics closed the initial
   public offering on June 22, 1999 and received net proceeds, after deducting
   underwriting commissions and offering expenses, of approximately $48.9
   million.

   over-allotment shares of common stock to its underwriters. The underwriters'
   over-allotment option was exercised at the initial public offering price of
   $12.00 per share. The net proceeds, after deducting underwriting commissions
   and offering expenses, were approximately $7.5 million.

6.    EQUITY INVESTMENTS

   provide Internet access via cable television portals worldwide. UTSC received
   20 percent of the initial outstanding common stock of AboveCable.com, Inc.
   and the exclusive rights to offer telemedicine and electronic health services
   at the portal level. United Therapeutics has agreed to provide the services

      (b) Quantum Medical Corporation
      In August 1999, Unither Telemedicine Services Corporation (UTSC) entered
   into an agreement to form Quantum Medical Corporation, a Delaware
   corporation, to develop and commercialize infrared wound healing technology.
   UTSC received approximately 35 percent of the initial outstanding common
   stock of Quantum Medical Corporation. United Therapeutics has agreed to
   provide the services of its Chief Executive Officer as Co-Chairman of the new
   company. The agreement does not require UTSC to contribute cash or other
   capital. From the date of the agreement until September 30, 1999, UTSC
   provided office space and administrative services pursuant to a lease with
   Quantum Medical Corporation for $3,000 per month, which lease terminated on
   November 1, 1999. At September 30, 1999, accounts receivable in the
   accompanying consolidated balance sheet includes $3,000 due from Quantum
   Medical Corporation. At September 30, 1999, UTSC's 35 percent investment in
   Quantum Medical Corporation was reported at zero and UTSC's equity in the
   underlying net assets was approximately $100,000. A member of United

7.    COMMITMENTS

      (a) Leases
      In September 1999, United Therapeutics purchased a building and property

   expected to continue in operation until their expiration, which will be at
   various dates through 2002. Additionally, a subsidiary of United Therapeutics
   subleased a portion of its office space to Quantum Medical Corporation (see
   note 6). The minimum annual rents due from tenants are approximately as

   eligible to participate in the Plan. The Plan provides for annual
   discretionary employer contributions. Employees may also contribute to the
   Plan at their discretion. For the nine month period ended September 30, 1999,
   no employer contributions were made to the Plan.

8.    LICENSE AGREEMENT

      In September 1999, United Therapeutics entered into an agreement with
   Shearwater Polymers, Inc. to obtain an exclusive right to Shearwater's
   know-how for the design, development, production, and use of pegylation
   technology to develop and produce sustained release prostacyclin molecules
   for the possible treatment of pulmonary hypertension, peripheral vascular
   disease, stroke, heart disease, cancer, and related diseases worldwide. In
   exchange, United Therapeutics paid Shearwater $100,000 in cash and agreed to
   pay Shearwater milestone payments of up to $2,900,000. Milestone payments
   will come due upon the achievement of certain product development goals set

   and are expected to be paid over a period of approximately six years. United
   Therapeutics also agreed to pay royalties ranging from 2 to 4 percent of net
   sales from developed products. Minimum annual royalties of $1,000,000 are
   required commencing with the thirteenth month following government approval
   of a developed product. License fees expensed as research and development for
   the quarter ended September 30, 1999 were $100,000.

9.    SUBSEQUENT EVENTS

      SynQuest, Inc.
      On October 7, 1999, United Therapeutics acquired all the outstanding stock
   of SynQuest, Inc. (SynQuest), an Illinois corporation engaged in the
   synthesis and manufacture of complex molecules. SynQuest manufactures UT-15,
   United Therapeutics' lead compound. The total cost of this acquisition was
   approximately $3.3 million, including transaction costs. Cash of $200,000 and
   United Therapeutics' common stock valued at $3.0 million was paid to the
   sellers as consideration. A holdback equivalent to $500,000 of United
   Therapeutics' common stock, which will be reduced to $200,000 of United
   Therapeutics' common stock on October 7, 2000, is being held in escrow for
   unknown liabilities and will be paid to the sellers over four years, subject
   to certain conditions.

      Goodwill and other intangibles resulting from the acquisition are expected
   to be approximately $2.6 million and will be amortized in a straight line
   manner over periods ranging up to five years. The acquisition will be
   accounted for as a purchase. Beginning on October 7, 1999, SynQuest's
   operations will be included in United Therapeutics' consolidated financial
   statements.


ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS

      The following discussion should be read in conjunction with the financial
statements and related notes appearing in the United Therapeutics' Registration
Statement on Form S-1 dated June 17, 1999. The following discussion contains
forward-looking statements concerning the cash needed for current research and
development contract obligations through the end of 1999, the adequacy of United
Therapeutics' resources to fund operations through 2002 and the anticipated
success and costs of United Therapeutics' efforts to become Year 2000 compliant.
These forward-looking statements reflect the plans and estimated beliefs of
management as of the date of this report. Actual results could differ materially
from those anticipated in the forward-looking statements. Factors that could
cause or contribute to such differences include those discussed below and in the
section "Risk Factors" in the Registration Statement, the accuracy of United
Therapeutics' assumptions concerning its contract research needs, and unexpected
developments in United Therapeutics' Year 2000 efforts.

OVERVIEW

      United Therapeutics develops pharmaceuticals to treat vascular diseases
including pulmonary hypertension and peripheral vascular disease, as well as
selected other chronic conditions. United Therapeutics commenced operations in
June 1996 and, since its inception, has devoted substantially all of its
resources to its research and development programs. United Therapeutics has
generated no product revenues and has funded its operations primarily from the
proceeds of the sale of its equity securities. United Therapeutics operates with
a minimal number of employees and has contracted with qualified third parties
for substantially all pharmaceutical development activities, including drug
manufacturing and certain key aspects of clinical trials.

      United Therapeutics has incurred net losses each year since inception and
had an accumulated deficit of $40.5 million at September 30, 1999. United
Therapeutics expects to continue to incur net losses and cannot provide
assurances that, in the future, it will have product sales or become profitable.

                                       7
<PAGE>   10

      United Therapeutics has contracted with various companies and research
organizations to coordinate and perform clinical trials and to provide other
activities related to the development of its lead product, UT-15, and other
products. It is anticipated that approximately $6.5 million in cash will be used
for the remainder of 1999 under these agreements. These expenses will be funded
from existing working capital.

FINANCIAL POSITION

      On June 17, 1999, United Therapeutics completed an initial public offering
of 4.5 million shares of common stock at $12.00 per share. The offering closed
on June 22, 1999 and United Therapeutics received net proceeds, after deducting
underwriting commissions and offering expenses, of approximately $48.9 million.
On July 16, 1999, United Therapeutics closed on the sale of 675,000
over-allotment shares to its underwriters and received net proceeds, after
deducting underwriting commissions and offering expenses, of approximately $7.5
million.

      Investments in marketable debt securities at September 30, 1999 were $53.9
million as compared to $10.0 million at December 31, 1998. The increase of
approximately $43.9 million is due to receipt of the net proceeds from the
initial public offering and the sale of the over-allotment shares, less amounts
used for operations during the nine months ended September 30, 1999.

      Accounts payable at September 30, 1999 were $2.2 million as compared to
$1.7 million at December 31, 1998. This increase in accounts payable is due to
clinical trial activities. The notes payable as of September 30, 1999 totaled
$1.8 million as compared to $314,000 as of December 31, 1998. A new mortgage
note payable was issued in June 1999 for $720,000, the proceeds from which were
used to pay off the original mortgage note payable. The new mortgage note is
secured by the building and property owned by United Therapeutics located at
1110 Spring Street in Silver Spring, Maryland. Another mortgage note payable was
issued in September 1999 for $1,078,000, the proceeds from which were used to
purchase 1106 Spring Street in Silver Spring, Maryland. That mortgage note is
secured by a certificate of deposit and building and property owned by United
Therapeutics located at that address.

      Common stock and additional paid-in capital at September 30, 1999
increased as compared to amounts at December 31, 1998. This increase of
approximately $67.4 million was due to the net proceeds of the initial public
offering of $48.9 million, sales of common stock through private placements
prior to commencement of the initial public offering totaling $2.0 million,
stock issued in exchange for an exclusive license agreement totaling $9.0
million, and approximately $7.5 million in net proceeds from the sale of
over-allotment shares to the underwriters.

RESULTS OF OPERATIONS

THREE MONTHS ENDED SEPTEMBER 30, 1999 AND 1998

      Revenue for the three months ended September 30, 1999 was approximately
$54,000, as compared to none for the same period in 1998. This revenue was
earned under an "orphan drug" grant awarded by the FDA related to United
Therapeutics' development of UT-15 for the treatment of primary pulmonary
hypertension. The FDA may designate a product as an "orphan drug" if the drug is
one intended to treat a rare disease or condition and has done so with respect
to UT-15.

      Research and development expenses consist primarily of costs to acquire
pharmaceutical products for development and amounts paid to contract research
organizations, hospitals and laboratories for the provision of services and
materials for drug development and clinical trials. Research and development
expenses were $6.0 million for the three months ended September 30, 1999, as
compared to $4.2 million for the three months ended September 30, 1998. This net
increase of approximately $1.8 million is due primarily to an increase of
approximately $3.1 million related to increased levels of patient enrollment in


                                       8
<PAGE>   11

United Therapeutics' clinical trials of UT-15, offset by a decrease of
approximately $1.5 million in licensing fees.

      General and administrative expenses consist primarily of personnel
salaries, office expenses and professional fees. General and administrative
expenses were $1.2 million for the three months ended September 30, 1999, as
compared to $595,000 for the three months ended September 30, 1998. This
increase was due primarily to increased staffing and related travel to support
expanded operations.

      Interest income for the three months ended September 30, 1999 was
$791,000, as compared to $174,000 for the three months ended September 30, 1998.
This increase was attributable primarily to an increase in the amount of cash
available for investing resulting from sales of common stock totaling
approximately $48.9 million during the second quarter of 1999, and $7.5
million during the third quarter of 1999, less amounts used for operations.


NINE MONTHS ENDED SEPTEMBER 30, 1999 AND 1998

      Revenue for the nine months ended September 30, 1999 was approximately
$161,000, as compared to none for the corresponding period in 1998. This revenue
was earned under the "orphan drug" grant awarded by the FDA related to United
Therapeutics' development of UT-15 for the treatment of primary pulmonary
hypertension.

      Research and development expenses consist primarily of costs to acquire
pharmaceutical products for development and amounts paid to contract research
organizations, hospitals and laboratories for the provision of services and
materials for drug development and clinical trials. Research and development
expenses were $22.8 million for the nine months ended September 30, 1999, as
compared to $7.0 million for the nine months ended September 30, 1998.
Approximately $6.1 million of the increase in research and development expenses
is related to increased levels of patient enrollment in United Therapeutics'
clinical trials of UT-15. Additionally, $9.1 million of the increase is related
to the payment in March 1999 of an up-front licensing fee consisting of common
stock valued at $9.0 million and $100,000 in cash to obtain the exclusive rights
to develop beraprost, an oral form of prostacyclin, to treat peripheral vascular
disease in the United States and Canada.

      General and administrative expenses consist primarily of personnel
salaries, office expenses and professional fees. General and administrative
expenses were $3.2 million for the nine months ended September 30, 1999, as
compared to $1.8 million for the nine months ended September 30, 1998. This
increase was due primarily to increased staffing and related travel to support
expanded operations.

      Interest income for the nine months ended September 30, 1999 was $1.2
million, as compared to $304,000 for the nine months ended September 30, 1998.
This increase was attributable to an increase in the amount of cash available
for investing resulting from sales of common stock since September 30, 1998,
less amounts used for operations.

LIQUIDITY AND CAPITAL RESOURCES

      Until June 1999, United Therapeutics financed its operations principally
through various private placements of common stock. On June 17, 1999, United
Therapeutics completed an initial public offering of 4.5 million shares of
common stock at $12.00 per share. Net proceeds to United Therapeutics, after
deducting underwriting commissions and offering expenses, were approximately
$48.9 million. On July 16, 1999, United Therapeutics' closed on the sale of
675,000 over-allotment shares to its underwriters and received net proceeds,
after deducting underwriting commissions and offering expenses, of approximately
$7.5 million.



                                       9
<PAGE>   12

      United Therapeutics' working capital at September 30, 1999 was $57.5
million, as compared with $15.1 million at December 31, 1998. Current
liabilities at September 30, 1999 were approximately $2.3 million, as compared
with $1.8 million at December 31, 1998. United Therapeutics' debt at September
30, 1999 was approximately $1.8 million, as compared with $314,000 at December
31, 1998, and consisted of two mortgage notes, one secured by a certificate of
deposit, and both secured by the buildings and property owned by United
Therapeutics located at 1106 - 1110 Spring Street in Silver Spring, Maryland and
are due in monthly installments over 30 years.

      Net cash used in operating activities was approximately $16.0 million and
$6.3 million for the nine months ended September 30, 1999 and 1998,
respectively. The increase resulted from the expansion of United Therapeutics'
operations, particularly with respect to increased costs for the UT-15 trials.
For the nine months ended September 30, 1999 and 1998, United Therapeutics
invested approximately $1.9 million and $1.2 million, respectively, in cash for
property, plant, and equipment. Net cash provided by financing activities was
approximately $59.9 million and $17.4 million for the nine months ended
September 30, 1999 and 1998, respectively. Cash flows from financing activities
for the nine months ended September 30, 1999 were derived primarily from private
equity financings in the first quarter, the initial public offering in June, and
the sale of the over-allotment shares to the underwriters in July. Cash flows
from financing activities for the nine months ended September 30, 1998 were
derived primarily from private equity financings during that period.

      United Therapeutics has contracted with various companies and research
organizations to coordinate and perform clinical trials and to provide other
activities related to the development of UT-15 and other products. It is
anticipated that approximately $6.5 million in cash will be used for the
remainder of 1999 under these agreements. These expenses will be funded from
existing working capital. United Therapeutics does not expect to make any
milestone or royalty payments during 1999.

      United Therapeutics expects that existing capital resources will be
adequate to fund its operations through 2002. United Therapeutics' future
capital requirements and the adequacy of its available funds will depend on many
factors, including:

   - Regulatory approval of UT-15 and beraprost;

   - Size and scope of its development efforts for additional products;

   - Cost, timing and outcomes of regulatory reviews;

   - Rate of technological advances;

   - Determinations as to the commercial potential of United Therapeutics'
   products under development;

   - Status of competitive products;

   - Defending and enforcing intellectual property rights;

   - Establishment, continuation or termination of third-party manufacturing
   arrangements;

   - Development of sales and marketing resources or the establishment,
   continuation or termination of third-party manufacturing arrangements;

   - Development of sales and marketing resources or the establishment,
   continuation or termination of third-party sales and marketing arrangements;
   and

   - Establishment of additional strategic or licensing arrangements with other
   companies.

      As of December 31, 1998, United Therapeutics had available approximately
$10.0 million in net operating loss carryforwards and $3.6 million in business
tax credit carryforwards for federal income tax purposes that expire at various
dates through 2018. As of September 30, 1999, United Therapeutics had available
approximately $29.1 million in net operating loss carryforwards and $8.8 million
in business tax credit carryforwards. United Therapeutics has not experienced
ownership changes as defined by rules enacted with the Tax Reform Act of 1986
that would limit United Therapeutics' ability to use its net operating loss and
tax credit carryforwards.

YEAR 2000

      United Therapeutics uses a number of computer software programs and
operating systems in its internal operations, including applications used in
financial business systems and various administrative functions. To the extent
that these software applications, and the software applications of United
Therapeutics' vendors, suppliers, financial institutions and service providers,
contain source code that is unable to appropriately interpret the upcoming
calendar year 2000, some level of modification or even possibly replacement of
such source code or applications will be necessary.

      United Therapeutics has identified the software applications that are not
Year 2000 compliant. United Therapeutics anticipates its Year 2000 remediation
efforts will be completed by December 1, 1999 and expects to incur expenses of
less than $100,000 to complete its remediation efforts.

      United Therapeutics has contacted all of its major vendors, suppliers,
financial institutions and service providers to ensure they are Year 2000
compliant. Key third party vendors have been asked to certify in writing that
their software or systems are Year 2000 compliant. United Therapeutics has
confirmed with MiniMed that the microinfusion devices used to deliver its key
drug, UT-15, to patients have been tested and are Year 2000 compliant.

      United Therapeutics believes its worst case scenario relating to Year 2000
risks includes a power interruption and a lack of pharmaceutical products to
support clinical trials. United Therapeutics is implementing a contingency plan
to cover this situation by building up inventories of its drug products to
sustain its studies for 12 months and has purchased a generator to deal with
power failures. United Therapeutics has now accelerated its spending on
inventory of its drug products in order to build up inventories.

RECENT ACCOUNTING PRONOUNCEMENTS

      In June 1998, the FASB issued SFAS No. 133, "Accounting for Derivative
Instruments and Hedging Activities." United Therapeutics is required to adopt
SFAS No. 133, as amended, for fiscal quarters beginning after June 15, 2000.
SFAS No. 133 established methods of accounting for derivative financial
instruments and hedging activities related to those instruments as well as other
hedging activities. Because United Therapeutics holds no derivative financial
instruments and does not engage in hedging activities, adoption of SFAS No. 133
is not expected to have a material impact on United Therapeutics' financial
condition or results of operations.

      In March 1998, the American Institute of Certified Public Accountants
issued Statement of Position, or "SOP", 98-1, "Accounting for the Costs of
Computer Software Developed or Obtained for Internal Use." SOP 98-1 requires
that entities capitalize certain costs related to internal-use software once
certain criteria have been met. United Therapeutics is required to implement SOP
98-1 for the year ending December 31, 1999. Adoption of SOP 98-1 is not expected
to have a material impact on United Therapeutics' financial condition or results
of operations.

      In April 1998, the American Institute of Certified Public Accountants
issued Statement of Position 98-5, "Reporting on the Costs of Start-Up
Activities." SOP 98-5 requires that entities expense the cost of start-up
activities including organization costs. United Therapeutics is required to
implement SOP 98-5 for the year ending December 31, 1999. Adoption of SOP 98-5
is not expected to have a material impact on United Therapeutics' financial
condition or results of operations.

PART II. OTHER INFORMATION

ITEM 2. CHANGES IN SECURITIES AND USE OF PROCEEDS

      (d) United Therapeutics registered 4,500,000 shares of its common stock,
par value $.01 per share, and an additional 675,000 shares of its common stock
for sale to the underwriters exclusively to cover over-allotments, on
Registration Statement on Form S-1, Commission File No. 333-76409. Deutsche Banc
Alex. Brown acted as lead manager of the underwriting. A.G. Edwards & Sons, Inc.
and Vector Securities International, Inc. acted as co-managers. The Securities
and Exchange Commission declared United Therapeutics' registration statement
effective on June 17, 1999.

      United Therapeutics closed the sale of 4,500,000 shares on June 22, 1999.
On July 13, 1999, the underwriters exercised their option to purchase the
over-allotment shares and on July 16, 1999 United Therapeutics closed the sale
of the 675,000 over-allotment shares. The aggregate price of the offering amount
registered, including the over-allotment shares, was $86,250,000 and the
aggregate offering price of the amount sold, including the over-allotment
shares, was $62,100,000. The offering is now terminated.

      From June 17, 1999 to September 30, 1999, the amount of expenses incurred
by United Therapeutics due to underwriting discounts and commissions, finders'
fees and expenses paid to or for underwriters for the sale of the 4,500,000
shares was $3,780,000 and a reasonable estimate of other expenses incurred by
United Therapeutics in connection with the offering is $39,300. Of the $39,300
in other expenses incurred, approximately $1,800 was paid to Mahon Patusky
Rothblatt & Fisher, Chartered, a law firm for which the Chief Executive Officer
of United Therapeutics serves as Of Counsel. The net proceeds to United
Therapeutics from the offering of the 4,500,000 shares, after deducting the
total expenses described above and expenses incurred prior to the effectiveness
of the registration statement, was approximately $48.9 million.

      On July 13, 1999, the underwriters exercised their option to purchase the
675,000 over-allotment shares. The amount of expenses incurred by United
Therapeutics due to underwriting discounts and commissions, finders' fees and
expenses paid to or for underwriters for the over-allotment shares was $567,000
and a reasonable estimate of other expenses incurred by United Therapeutics in
connection with the over-allotment exercise is $18,500. Of the $18,500 in other
expenses incurred, approximately $3,500 was paid to Mahon Patusky Rothblatt &
Fisher, Chartered, a law firm for which the Chief Executive Officer of United
Therapeutics serves as Of Counsel. The net proceeds to United Therapeutics from
the sale of the 675,000 over-allotment shares, after deducting the total
expenses described above, was approximately $7.5 million.

      From June 22, 1999 to September 30, 1999, United Therapeutics temporarily
invested all the net proceeds from the offering of the 4,500,000 shares in
marketable debt securities. United Therapeutics temporarily invested all of the
net proceeds from the sale of the 675,000 over-allotment shares in marketable
debt securities and money market funds. The net proceeds from the offering and
the over-allotment sale were added to cash equivalents and investments of United
Therapeutics on hand at the time of the offering of approximately $9 million.
The net proceeds remain temporarily invested and have not yet been applied.

         (a)     On the date which is one year from the Closing Date, the
Escrow Agent shall distribute from Escrow to the Stockholders other than Davis,
pro rata in accordance with their percentage ownership of the Company on the
date hereof, certificates representing all remaining shares of the UT Stock
Holdback less (i) that number of shares of UT Stock then equal in value (based
on the then Market Price of UT Stock) to the amount of the Offset under Section
6.3 below, if any; and (ii) that number of shares of UT Stock then equal in
value to the sum of $200,000 (based on the then Market Price of UT Stock).

         (b)     On the date which is four years from the Closing Date, the
Escrow Agent shall distribute from Escrow to the Stockholders other than Davis,
pro rata in accordance with their percentage ownership of the Company on the

account in connection with the Escrow disbursement contemplated by Section
1.7(a) above.

take any action that would cause the Merger to fail to qualify as a
reorganization within the meaning of Section 368(a) of the Code.  Following the
Effective Time, UT shall use its reasonable best efforts to conduct its
business in a manner that would not jeopardize the characterization of the
Merger as a reorganization within the meaning of Section 368(a).  UT presently
intends to continue and shall continue for periods after the Effective Time at
least one significant historic business line of the Company, or use at least a
significant portion of the Company's historic business assets in a business, in
each case within the meaning of Treasury Regulation Section 1.368-1(d).

1.12     Additional Actions.

(except as otherwise provided at Section 2.34 to indemnify, defend and hold
Acquisition Subsidiary, the Surviving Corporation and their respective
Affiliates, officers, directors, shareholders, employees and agents harmless
from and against any and all losses, liabilities, damages, claims, demands,
costs, obligations, deficiencies and expenses (including without limitation
interest, penalties and reasonable attorneys' fees and expenses and, in the
case of environmental matters, reasonably necessary facility and equipment
repairs, modifications and additions) (collectively and including without
limitation Tax Losses, "LOSSES") which arise, or result, directly or
indirectly, from:

                 (i)      Representations, Warranties and Covenants -- except
as otherwise provided herein, any material breach of or failure to perform, any
representation, warranty, covenant or obligation of any of the Stockholders or
the Company in this Agreement or in any Schedule or certificate delivered
pursuant hereto;

                 (ii)     Identified Claims and Litigation Matters (Designated

with the claims and litigation matters against the Company which are identified
on Schedule 6.1(a)(ii) (such claims and matters, the "DESIGNATED CLAIM"; Losses

<PAGE>   39
                 (iii)    Liabilities -- any and all liabilities, debts, or
obligations, known or unknown, fixed or contingent, liquidated or unliquidated,
secured or unsecured, direct or indirect, or of any other kind, of the Company,
which arose or accrued prior to Closing, other than (i) liabilities
specifically disclosed and identified as to amount on the Stub Balance Sheet or

(Designated Claims).  The foregoing liabilities shall include, without
limitation, any and all losses that the Surviving Corporation might incur by
reason of any claim, suit, demand or action alleging that the operation of the
Business of the Company prior to Closing conflicted with, infringed upon or
misappropriated the Proprietary Rights of any third party, only to the extent
covered by Stockholders' warranties and representations under this Agreement;
and

                 (iv)     Taxes -- in addition to Losses resulting from any

(all such Losses in this clause (vi) with respect to Tax matters are referred
to herein as "TAX LOSSES").

         (b)   Acquisition Subsidiary agrees, jointly and severally, to
indemnify, defend and hold Stockholders harmless from and against any and all
Losses which arise or result, directly or indirectly, from any breach of or
failure to perform, any representation, warranty, covenant or obligation of the
Acquisition Subsidiary in this Agreement.



6.2      Notice of Claims.

         (a)     If an indemnified party reasonably believes that it may incur
any Losses hereunder, or receives notice of a third-party claim for which it
intends to seek indemnification hereunder, it shall give the indemnifying party
prompt written notice of such claim, specifying the facts and circumstances of
the indemnification claim and the estimated amount of the Losses.

         (b)     The indemnifying party under this Section 6.2 shall have the
right to conduct and control, through counsel of its own choosing but
reasonably acceptable to the indemnified party, any third-party claim, action
or suit or compromise or settlement thereof but only so long as prior to
assuming the conduct or control of such claims, action or suit, the
indemnifying party confirms in writing to the indemnified party that such
claim, action or suit is one in respect of which the indemnifying party is
obligated to provide indemnification under this Agreement.  The indemnified
<PAGE>   40
party may, at its election, participate in the defense of any such claim,
action or suit through counsel of its own choosing, but the fees and expenses
of such counsel shall be at the expense of the indemnified party, unless the
indemnified party shall have been advised by such counsel that there are one or
more legal defenses available to it that are inconsistent and conflicting with
those available to the indemnifying party (in which case, if the indemnified
party notifies the indemnifying party in writing that it elects separate
counsel at the expense of the indemnifying party, the indemnifying party shall
not have the right to assume the defense of such action on behalf of the
indemnified party with respect to such defenses).  If the indemnifying party
shall fail to defend promptly and aggressively any such third-party claim,
action or suit, then the indemnified party may defend, through counsel of its
own choosing, such claim, action or suit and may settle such claim, action or
suit and recover from the indemnifying party the amount of such settlement or
of any judgment and the costs and expenses of such defense.  The obligations of
the indemnifying party hereunder shall not be reduced as a result of any action
by the party furnishing the notice of third-party claim responding to such
claim if such action is reasonably required to minimize damages or to avoid a
forfeiture or penalty or to comply with a requirement imposed by law.  The
indemnifying party shall not compromise or settle any third-party claim, action
or suit that includes any term which shall require any act or forbearance by
the indemnified party and which does not unconditionally release the
indemnified party from all liability in respect of such claim, action or suit
without the prior written consent of the indemnified party.  Acquisition
Subsidiary and Stockholders shall cooperate in all reasonable respects with
each other in connection with the defense, negotiation or settlement of any
legal proceeding, claim or demand referred to in this Section 6.2.

         (c)     Notwithstanding any of the foregoing:

                 (i)      UT and the Surviving Corporation shall be entitled to
control any audit,  contest, or proceeding involving Taxes, but shall allow,
and shall cause the Subsidiaries to allow, the Stockholders to be present with
the Surviving Corporation at all meetings with Tax authorities in respect of
audits, and to be present at all other proceedings and hearings with respect to
all Tax contests, to the extent such meetings, proceedings or hearings relate
to the Tax returns of the Company with respect to periods on or prior to the
Closing in respect of which UT or the Acquisition Subsidiary seek
indemnification from Stockholders.  Stockholders shall also be entitled to make
any reasonable written submissions in respect of such Tax audits, proceedings
and hearings, provided that all positions taken in such submissions are based
upon substantial authority, are made in good faith, and are prepared by counsel
of recognized national standing, and further provided that prior to making such
submissions, Stockholders shall afford Acquisition Subsidiary reasonable
opportunity to review and comment on such submissions.  UT and the Surviving
Corporation will not settle any such Tax audit, proceeding or contest in a
manner that would adversely affect any of the Stockholders without the prior
written consent of such Stockholders, which consent shall not be unreasonably
withheld, conditioned or delayed.  Stockholders' consent shall be deemed to
have been given in the event Stockholders fail to respond to and disapprove of
the Surviving Corporation's request for consent within 5 Business Days of
notice given pursuant to the provisions of Section 7.5.

                 (ii)     Notwithstanding the procedure detailed in Section
6.2(c)(i) above, in the
<PAGE>   41
event that UT or the Surviving Corporation has no exposure to potential Taxes
and the impact of any Taxes would fall solely on the Stockholders then, in such
event, the Stockholders may control any audits, contests or proceedings but
shall allow UT and the Surviving Corporation to be present at all meetings with
Tax authorities in respect of audits, and to be present at all other
proceedings and hearings with respect to all Tax contests, and to receive
copies of all correspondence to and from tax authorities, to the extent such
meetings, proceedings, hearings or correspondence relate to the Tax returns of
the Company.  In the event that during the course of Stockholders' control of
any audits, contests or proceedings, the Surviving Corporation or UT becomes
exposed to potential Taxes and the impact of any Taxes would fall on the
Surviving Corporation or UT then, in such event, the Surviving Corporation and
UT shall be entitled to immediately control any audit, contest, or proceeding
as provided in Section 6.2(c)(i) above.

                 (iii)    Acquisition Subsidiary shall have the right to
conduct and control the claims and litigation the subject of indemnification
pursuant to Section 6.1(a)(ii) (Designated Claims), subject to the following:

                          (A)  To the extent that the total cumulative
Designated Claim Losses are in excess of $250,000, prior to settling such
Designated Claims, the Surviving Corporation shall secure the approval of
Stockholders of such settlement, which approval shall not be unreasonably
withheld or delayed.  Stockholders' approval shall be deemed to have been given
in the event Stockholders fail to respond to and disapprove of the Surviving
Corporation request for approval within 5 Business Days of notice given
pursuant to the provisions of Section 7.5; and

                          (B)  The Surviving Corporation shall continue to use
counsel handling the Designated Matters reasonably acceptable to the
Stockholders.

6.3      Offset.

         (a)     Subject to Section 6.4, Acquisition Subsidiary shall have the
right to offset from the UT Stock Holdback pursuant to Section 1.4 any amounts
representing Losses (including Tax Losses) resulting to either of the Surviving
Corporation  or UT as a result of any indemnification claim contained in this
Agreement.  Subject to the limitations of Section 6.4, exercise of the offset
rights under this Section 6.3(a) and Section 6.3(b) by the Surviving
Corporation or UT shall not limit the rights of the Surviving Corporation or UT
to recover any amounts owed to any of them that exceed the amount obtained by
exercise of those rights and such exercise shall not be in substitution of or
in any way limit the exercise by either of the Surviving Corporation or UT, of
their other rights and remedies.  Stockholders acknowledge and agree that the
exercise of its rights pursuant to this Section 6.3(a) and pursuant to Section
6.3(b) by the Surviving Corporation or UT shall not limit the rights of the
Surviving Corporation or UT to recover any amounts owed to any of them that
exceed the amount obtained by exercise of those rights and such exercise shall
not limit the exercise by either of the Surviving Corporation or UT of their
other rights and remedies under this Agreement.

         (b)     In the event that on the date payment of the net UT Stock
Holdback retained pursuant to Section 1.7 there are then pending third-party
claims which give rise to rights to indemnification in favor of the Surviving
Corporation or UT, and their respective Affiliates,
<PAGE>   42
officers, directors, shareholders, employees and agents under this Article 6
which have not been fully resolved or settled, the Surviving Corporation or UT
shall be entitled to exercise the set-off rights provided above with respect to
such claims by withholding from the UT Stock Holdback an amount equal to the
reasonable assessment of the amount of Losses that are likely to be incurred by
the Surviving Corporation or UT in respect of such claims.  In connection with
such exercise of set-off rights, the Surviving Corporation or UT shall give
written notice to Stockholders of the amount of its assessment of the Losses in
question.  If Stockholders disagree with assessment of the Losses by the
Surviving Corporation or UT, they shall give written notice to the Surviving
Corporation or UT of their objection no later than 30 days after receipt of the
first notice from the Surviving Corporation or UT.  If the parties are unable
to resolve their differences within 30 days of Stockholders' notice to the
Surviving Corporation or UT, the matter shall be submitted to KPMG, Washington,
D.C., for the Surviving Corporation or UT, and Blackman, Kallick and
Bartelstein for Seller, to arrive at a proposed resolution on Losses
assessment.  In the event that KPMG and Blackman, Kallick and Bartelstein
arrive at a mutual recommendation, it shall be adopted by the parties.  In the
event that KPMG and Blackman, Kallick and Bartelstein are unable to arrive at a
mutual recommendation, then KPMG and Blackman, Kallick and Bartelstein shall
agree upon a third CPA firm to act as an arbitrator (the "ACCOUNTING
ARBITRATOR") for a final determination of the reasonable assessment of the
amount of Losses that are likely to be incurred in respect of such claim.  If
the Accounting Arbitrator determines that the amount withheld by the Surviving
Corporation or UT is in excess of the amount of Losses that are likely to be
incurred by the Surviving Corporation or UT, then the Surviving Corporation or
UT shall release the excess amount, to the Stockholders.  The fees and expenses
of the Accounting Arbitrator shall be borne equally by the Surviving
Corporation or UT, on the one hand, and by the Stockholders, on the other.
Each of the parties shall bear its own attorneys' and accountants' fees and
expenses incurred in connection with resolution of the matter by the Accounting
Arbitrator.

6.4      Limitations.

         (a)     No Losses shall be payable by Stockholders pursuant to Section
6.l(a)(i) (Representations, Warranties and Covenants), Section 6.l(a)(iv)

Surviving Corporation or UT against Stockholders exceeds Twenty-Five Thousand

amount of such Losses exceeds the Deductible Amount, the Surviving Corporation
or UT shall be entitled to be indemnified for the amount of such Losses in

Losses the subject of Section 6.l(a)(ii) (Designated Claims) and such Losses
shall be subject only to such deductible or threshold as set expressly set

three (3) years from the Closing Date shall terminate as the end of the period

claim prior to the end of such period.

circumstances, equals or exceeds $5,000, at which point, the Surviving

7.6      Law Governing: Arbitration.

         (a)     This Agreement shall be construed in accordance with of the
State of New York.

         (b)     Any controversy or claim arising out of or relating to this
Agreement, or to any breach thereof, shall be finally resolved by arbitration
pursuant to this Section 7.8.  To institute the provisions of this paragraph,
the party desiring to institute the procedure shall first notify the other
party and then both parties shall attempt to resolve the claim within fifteen
(15) Business Days.  In the event the parties cannot resolve the claim within
such time period, the matter shall be submitted to the American Arbitration
Association ("AAA") in accordance with the Commercial Arbitration Rules of the
American Arbitration Association as they exist on the date of this Agreement.
The parties agree that the exclusive proper place of venue for any arbitration
hearing shall be New York, NY.  The parties agree that the arbitrator(s) may
grant any relief that could have been granted if the case were determined by
the civil courts of general jurisdiction.  If, however, the arbitrator(s)
determine(s) that he or she is or they are not empowered to exercise the
equitable powers of the courts, the party being denied the equitable relief may
have the matter tried by the civil courts.
<PAGE>   47
Each of the parties consents to the jurisdiction of the state and federal
courts sitting in New York, NY (and of the appropriate appellate courts), in
any such action or proceeding and waives any objection to venue laid therein.
In addition, nothing contained herein shall prevent Acquisition Subsidiary or
their Affiliates from pursuing any remedies, including but not limited to any
of the remedies afforded hereunder, in any courts or other tribunals in which
any labor dispute or action involving any employment contract may be pending
with any of the Stockholders.  Process in respect of litigation or arbitration
may be served on any party by mail, in addition to every other method permitted
by law.

7.7      Assignability; Successors.

         The Stockholders may not assign any of their rights or obligations

such notice shall cover a transfer by such partnership to its partners and
provided, further, however, that the shares so transferred shall remain subject
to this Agreement.  Each certificate representing the Restricted Stock
transferred as above provided shall bear the legend set forth in Section 2,
unless (i) such transfer is in accordance with the provisions of Rule 144 (or
any other rule permitting public sale without registration under the Securities
Act) and is not made by an affiliate of the Company or (ii) the opinion of
counsel referred to above is to the further effect that the transferee and any
subsequent transferee (other than an affiliate of the Company) would be
entitled to transfer such securities without registration under the Securities
Act.

         The foregoing restrictions on transferability of Restricted Stock
shall terminate as to any particular shares of Restricted Stock when such
shares shall have been effectively registered under the Securities Act and sold
or otherwise disposed of in accordance with the intended method of disposition
by the seller or the sellers thereof set forth in the registration statement
concerning such shares.  Whenever a holder of Restricted Stock is able to
demonstrate to the Company (and its counsel) that the provisions of Rule 144(k)
of the Securities Act are available to such holder without limitation, such
holder of Restricted Stock shall be entitled to receive from the Company,
without expense, a new certificate not bearing the restrictive legend set forth
in Section 2 in exchange for the surrender of the existing certificate, which
shall be marked canceled by the Company.

         4.  Incidental Registration.  If the Company at any time proposes to
register any of its Common Stock under the Securities Act for sale to the
public, whether for its own account or for the account of other security
holders or both (except with respect to registration statements on Form S-4 or
S-8 or another form not available for registering the Restricted Stock for sale
to the public), it will give written notice at such time to all holders of
outstanding Restricted Stock of its intention to do so.  Upon the written
request of any such holder, given within 20 days after receipt of





                                       3
<PAGE>   4
any such notice by the Company, to register any of its Restricted Stock (which
request shall state the intended method of disposition thereof), the Company
will use its best efforts to cause the Restricted Stock as to which
registration shall have been so requested to be included in the securities to
be covered by the registration statement proposed to be filed by the Company,
all to the extent


requisite to permit the sale or other disposition by the holder in accordance
with its written request) of such Restricted Stock.  In the event that any
registration pursuant to this Section 4 shall be, in whole or in part, an
underwritten public offering of Common Stock, the Company shall specify that
either (i) such Restricted Stock is to be included in the underwriting on the
same terms and conditions as the shares of Common Stock otherwise being sold
through underwriters under such registration, or (ii) such Restricted Stock is
to be sold in the open marker without any underwriting, on terms and conditions
comparable to those normally applicable to offerings of common stock in
reasonably similar circumstances.  In any such underwritten public offering of
Common Stock, if, in the opinion of the managing underwriter, the Restricted
Stock so requested to be registered would adversely affect the marketing of
such Common Stock, the Company shall include in such registration, to the
extent of the number which the Company is advised can be sold in such offering,
(x) first, securities proposed by the Company to be sold for its own account,
(y) second, Restricted Stock requested to be included in such registration by
the holder or holders thereof and other securities of the Company requested to
be included in such registration pursuant to registration rights granted by the
Company to the holders of such securities prior to the date hereof, pro rata
among the requesting holders of Restricted Stock and such other securities
based upon the number of shares of Restricted Stock and such other Securities
requested to be registered,  and (z) third, other securities of the Company
requested to be included in such registration (other than as described in
clause (y) above).

         5.  Registration Procedures.  If and whenever the Company is required
by the provisions of Section 4 hereof to use its reasonable best efforts to
effect the registration of any of the Restricted Stock under the Securities
Act, the Company will, as expeditiously as possible:

                 a.       prepare (and afford counsel for the selling holders
reasonable opportunity to review and comment thereon) and file with the
Commission a registration statement with respect to such securities and use its
best efforts to cause such registration statement to become and remain
effective for the period of the distribution contemplated thereby (determined
as hereinafter provided);

                 b.       prepare (and afford counsel for the selling holders
reasonable opportunity to review and comment thereon) and file with the
Commission such amendments and supplements to such registration statement and
the prospectus





                                       4
<PAGE>   5
used in connection therewith as may be necessary to keep such registration
statement effective for the period specified in paragraph 5(a) above and as
shall comply with the provisions of the Securities Act with respect to the
disposition of all Restricted Stock covered by such registration statement for
such period;

                 c.       furnish to each seller and to each underwriter such
number of copies of the registration statement and the prospectus included
therein (including each preliminary prospectus) as such persons may reasonably
request in order to facilitate the public sale or other disposition of the
Restricted Stock covered by such registration statement;

                 d.       use its best efforts to register or qualify the
Registered Stock covered by such registration statement under the securities or
blue sky laws of such jurisdictions as the sellers of Restricted Stock or, in
the case of an underwritten public offering, the managing underwriter, shall
reasonably request, and use its best efforts to list all Restricted Stock
covered by such registration statement on any securities exchange on which any
other securities exchange on which any other securities of the same class as
the Restricted Stock are then listed;

                 e.       immediately notify each seller under such
registration statement and each underwriter, at any time when a prospectus
relating thereto is required to be delivered under the Securities Act, of the
happening of any even as a result of which the prospectus contained in such
registration statement, as then in effect, includes an untrue statement of a
material fact or omits to state any material fact required to be stated therein
or necessary to make the statements therein now misleading in the light of the
circumstances then exiting;

                 f.       use its best efforts (if the offering is
underwritten) to furnish, at the request of any seller, on the date that
Restricted Stock is delivered to the underwriters for sale pursuant to such
registration:  (i) an opinion dated such date of counsel representing the
Company for the purposes of such registration, addressed to the underwriters
and to such seller, stating that such registration statement has become
effective under the Securities Act and that (A) to the knowledge of such
counsel, no stop order suspending the effectiveness thereof has been issued and
no proceedings for that purpose  have been instituted or are pending or
contemplated under the Securities Act, (B) the registration statement, the
related prospectus, and each amendment or supplement thereof, comply as to form
in all material respects with the requirements of the Securities Act and the
applicable rules and regulations of the Commission thereunder (except that such
counsel need express no opinion as to financial statements contained therein or
any information provided by the underwriters or the sellers) and (C) to such
other effects as may reasonably be requested by counsel for the underwriters,
and (ii) a letter dated such date from the independent public accountants
retained by the Company, addressed to the underwriters and to such seller,
stating that they are independent public accountants within the meaning of the
Securities Act and that,





                                       5
<PAGE>   6
in the opinion of such accountants, the financial statements of the Company
included in the registration statement or the prospectus, or any amendment or
supplement thereof, comply as to form in all material respects with the
applicable accounting requirements of the Securities Act, and such letter shall
additionally


cover such other financial matters (including information as to the period
ending no more than five business days prior to the date of such letter) with
respect to the registration in respect of which such letter is being given as
such underwriters or seller may reasonably request; and

                 g.       make available for inspection by each seller, any
underwriter participating in any distribution pursuant to such registration
statement, and any attorney, accountant or other agent retained by such seller
or underwriter, all financial and other records, pertinent corporate documents
and properties of the company, and cause the Company's officers, directors and
employees to supply all information reasonably requested by any such seller,
underwriter, attorney, accountant or agent in connection with such registration
statement and permit such seller, attorney, accountant or agent to participate
in the preparation of such registration statement.

For purposes of paragraphs (a) and (b) above, the period of distribution of
Restricted Stock in a firm commitment underwritten public offering shall be
deemed to extend until each underwriter has completed the distribution of all
securities purchased by it, and the period of distribution of Restricted Stock
in any other registration shall be deemed to extend until the earlier of the
sale of all Restricted Stock covered thereby or six months after the effective
date thereof.

         In connection with each registration hereunder, the selling holders of
Restricted Stock will furnish to the Company in writing such information with
respect to themselves and the proposed distribution by them as shall be
reasonably necessary in order to assure compliance with federal and applicable
state securities laws.

         In connection with each registration pursuant to Section 4 hereof
covering an underwritten public offering, the company agrees to enter into a
written agreement with the managing underwriter selected in the manner herein
provided in such form and containing such provisions as are customary in the
securities business for such an arrangement between underwriters and companies
of the Company's size and investment stature, provided that such agreement
shall not contain any such provision applicable to the Company which is
inconsistent with the provisions hereof and provided, further, that the time
and place of the closing under said agreement shall be as mutually agreed upon
among the Company and such underwriter.

         6.  Expenses.  All expenses incurred by the Company in complying with
Section 4 hereof, including, without limitation, all registration and filing
fees, printing expenses, fees and disbursements of counsel and independent
public accountants for the Company, fees of the National Association of
Securities Dealers, Inc. or any successor thereto, transfer taxes, fees or
transfer agents and


registrars, and costs of insurance, but excluding any Selling Expenses, are

         The Company will pay all Registration Expenses in connection with each
registration statement filed pursuant to Section 4 hereof. All Selling Expenses
in connection with any registration statement filed pursuant to Section 4
hereof shall be borne by the participating sellers in proportion to the number
of shares sold by each, or by such persons other than the Company (except to
the extent the Company shall be a seller) as they may agree.

         7.  Representations and Warranties of the Company.  The Company
represents and warrants to you as follows:

                 a.       The execution, delivery and performance of this
Agreement by the Company have been duly authorized by all requisite corporate
action and will not violate any provision of law, any order of any court or
other agency of government, the Certificate of Incorporation or By-laws of the
Company, or any provision of any indenture, agreement or other instrument to
which it or any of its properties or assets is bound, or conflict with, result
in a breach of or constitute (with due notice or lapse of time or both) a
default under any such indenture, agreement or other instrument, or result in
the creation or imposition of any lien, charge or encumbrance of any nature
whatsoever upon any of the properties or assets of the Company.

                 b.       This Agreement has been duly executed and delivered
by the Company and constitutes the legal, valid and binding obligation of the
Company, enforceable in accordance with its terms, subject to applicable
bankruptcy, insolvency, reorganization, moratorium and other similar laws from
time to time in effect affecting the enforcement of creditors rights generally
and to general equitable principles.

         8.  Rule 144 Reporting.  The Company agrees with you as follows:

from and after the date it is first required to do so.





                                       7
<PAGE>   8
                 b.       The Company shall file with the Commission in a
timely manner all reports and other documents as the Commission may prescribe

such reporting requirements of the Exchange Act.

                 c.       The Company shall furnish to such holder of
Restricted Stock forthwith upon request (i) a written statement by the Company

from and after the date it first becomes subject to such reporting
requirements), and of the Securities Act and the Exchange Act (at any time
after it has become subject to such reporting requirements), (ii) a copy of the
most recent annual or quarterly report of the Company, and (iii) such other
reports and documents so filed as a holder may reasonably request to avail
itself of any rule or regulation of the Commission allowing a holder of

         9.  Miscellaneous.

                 a.       All covenants and agreements contained in this
Agreement by or on behalf of any of the parties hereto shall bind and inure to
the benefit of the respective successors and assigns of the parties hereto
whether so expressed or not.  Without limiting the generality of the foregoing,
the registration rights conferred herein on the holders of Restricted Stock
shall inure to the benefit of any and all subsequent holders from time to time

Restricted Stock shall be required to bear the legend specified in Section 2
hereof.

                 b.       This Agreement shall be governed by and construed in
accordance with the law of the State of Delaware.

                 c.       No change, modification, extension, termination or

valid unless made in writing and signed by duly authorized representatives of
the parties

                 d.       If any provision of this Agreement is found to be
invalid or unenforceable in any jurisdiction, it shall be ineffective to the
extent of such invalidity or unenforceability in such jurisdiction, without
rendering invalid or unenforceable the remaining provisions hereof and without
affecting the validity or unenforceability of any of the terms of this
Agreement in any other jurisdiction.  The parties agree to renegotiate in good
faith any term held invalid and be bound by the mutually agreed substitute
provision.

Company any you.
