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

                    SEPARATION AGREEMENT AND GENERAL RELEASE

          THIS SEPARATION AGREEMENT AND GENERAL RELEASE ("Agreement") is entered
                                                          ---------
into by and between Jane Taylor ("Executive") and AmericasDoctor.com, Inc. (the
                                  ---------
"Company").
 -------

          Executive and the Company desire to settle fully any and all matters
between them, including, but not limited to, any matters relating to Executive's
employment with the Company, Executive's Employment, Confidentiality and
Non-Competition Agreement with the Company, dated as of April 22, 1998, a copy
of which is attached hereto and is hereby incorporated in part by reference
herein ("Employment Agreement") and Executive's Severance Agreement with the
         --------------------
Company, dated as of April 22, 1998, a copy of which is attached hereto
("Severance Agreement"), and the termination of Executive's employment.
  -------------------
Therefore, in consideration of the mutual promises set forth herein and other
good and valuable consideration, the receipt and sufficiency of which is
acknowledged, Executive and the Company agree as follows:

1. Termination of Employment. Executive's employment with the Company is
terminated effective December 31, 2001 ("Termination Date"). Executive further
                                         ----------------
waives and releases any claim that she has or may have to reemployment with the
Company, or any of its subsidiary companies, affiliates, successors or assigns.

2. Employment Agreement. Per the terms of the Employment Agreement, for a period
of one year following the Termination Date (the "Payment Period"), the Company
                                                 --------------
shall pay to Executive, in accordance with the Company's regular payroll
schedule, pro rata termination payments in the aggregate amount of $155,250,
less applicable taxes, deductions and withholdings, to be distributed
semi-monthly during the Payment Period, commencing as of the Termination Date.
Executive agrees to comply with all of her continuing obligations under the
Employment Agreement, including, without limitation, paragraphs 10, 11, 12 and
15 of the Employment Agreement; provided, however, that (a) each party hereto
                                --------  -------
acknowledges that the business currently being conducted by The Geneva
Foundation shall not be deemed to be a Competing Enterprise for purposes of
paragraph 11 of the Employment Agreement, and (b) the provisions of paragraph
11(c) of the Employment Agreement shall not apply to Ms. Judy Moyer.

3.   Benefits.

     (a) Executive acknowledges that the Company's currently-existing 401(k)
     Plan does not permit Executive to continue to making contributions into
     such 401(k) Plan during the Payment Period. In lieu of matching
     contributions that the Company would have made for Executive's account
     during the Payment Period if Executive continued to participate in the
     401(k) Plan during the Payment Period, the Company shall pay to Executive,
     in the form of a check (which may be added to the amounts due under
     paragraph 2 above) and at such time as it applies matching funds to the
     accounts of other 401(k) Plan participants, an amount equal to such
     matching amount, less applicable withholding taxes;

<PAGE>

     (b) Notwithstanding anything to the contrary in the Executive's stock
     option agreement(s) or certificate(s) or in the stock option plan(s) under
     which Executive's stock options were granted, all of Executive's stock
     options that would have vested in the twenty-four (24) months following the
     Termination Date if Executive had remained employed by the Company during
     such period will automatically become fully vested and exercisable on the
     date that is immediately prior to the Termination Date, and Executive shall
     have the right to exercise any stock options that vested on or before the
     Termination Date (including such accelerated options) at any time no later
     than the date that is twenty-four (24) months after the Termination Date.
     Executive agrees that any and all right to options rights are otherwise
     governed by the stock option certificate(s) and related agreement(s).

     (c) The Executive will be entitled to continuation coverage under COBRA and
     the date of her qualifying event shall be the Termination Date.

     (d) The Company shall pay Executive for up to 100 accrued but unused
     vacation hours, to be determined as of the Termination Date, which vacation
     hours shall be paid on a pro rata basis at 75% of Executive's annual base
     salary of $155,250, and be payable in a lump sum to be added to Executive's
     first paycheck received from the Company under Section 2 above.

The payments and benefits referred to above shall be in lieu of and discharge
any obligations of the Company to Executive for compensation, wages, benefits,
vacation, pain and suffering, or any other expectation of remuneration or
benefit on the part of Executive, set forth in the Employment Agreement or
otherwise. Other than the obligations set forth in paragraphs 2 and 3, Executive
acknowledges that the Company shall have no other obligations to Executive under
this Agreement, the Employment Agreement or the Severance Agreement. Executive
further agrees not to seek any further compensation or benefits from the
Company.

4. No Authority. Executive understands and agrees that effective on the
Termination Date, Executive is no longer authorized to incur any expenses,
obligations, or liabilities on behalf of the Company.

5. Return of Company Property. Executive agrees to immediately turn over to the
Company any and all files, computers, memoranda, notes, records, reports,
photographs, drawings, plans, papers, or other documents (whether paper or
electronic), intellectual property, physical or personal property, obtained by
Executive during the course of her employment with the Company, or any of its,
subsidiary companies, affiliates, successors or assigns, and that are the
property of the Company, or any of its, subsidiary companies, affiliates,
successors or assigns.

6. Complete Release. As a material inducement to the Company to enter into this
Agreement, and per the terms of paragraph 9(a) of the Employment Agreement, the
Executive hereby forever releases and discharges the Company, its subsidiaries,
owners, affiliates, divisions, stockholders, directors, officers, members,
agents, current and former employees, attorneys, related companies,
predecessors, successors and assigns (collectively "Released Parties"), and each
                                                    ----------------

7. No Claims. Executive represents that Executive has not filed any complaints,
charges, or lawsuits with any local, state, or federal agency or court against
the Company or any of the Released Parties, that Executive will not do so at any
time based on any claim that arose on or before the execution of this Agreement,
and that if any such agency or court assumes jurisdiction of any such charge,
complaint, or lawsuit against the Company or any of the Released Parties on

its parent companies, subsidiary companies, affiliates, successors or assigns,
including, but not limited to, any plans, strategies, marketing and sales

of this Agreement for Executive's review and consideration is withdrawn in its
entirety at that time. Executive further understands that Executive has seven

                     REVOLVING CREDIT AND SECURITY AGREEMENT

          THIS REVOLVING CREDIT AND SECURITY AGREEMENT (the "Agreement") dated
as of March 15, 2002, is entered into among AMERICASDOCTOR, INC., a Delaware
corporation, AMERICADOCTORS INTERNET OPERATIONS, INC., a Delaware corporation
and AMERICASDOCTORS.COM COORDINATOR SERVICES, INC., a Delaware corporation
(collectively the "Borrower"), and CAPITALSOURCE FINANCE LLC, a Delaware limited
liability company ("Lender").

          WHEREAS, Borrower has requested that Lender make available to Borrower
a revolving credit facility (the "Revolving Facility") in a maximum principal
amount at any time outstanding of up to Four Million Dollars ($4,000,000) (the
"Facility Cap"), the proceeds of which shall be used by Borrower for refinancing
Borrower's existing obligations and indebtedness and working capital needs; and

          WHEREAS, Lender is willing to make the Revolving Facility available to
Borrower upon the terms and subject to the conditions set forth herein.

          NOW, THEREFORE, in consideration of the foregoing and for other good
and valuable consideration, the receipt and adequacy of which hereby are
acknowledged, Borrower and Lender hereby agree as follows:

I.   DEFINITIONS

     1.1 General Terms

          For purposes of this Agreement, in addition to the definitions above
and elsewhere in this Agreement, the terms listed in Appendix A hereto shall
                                                     ----------
have the meanings given such terms in Appendix A, which is incorporated herein
                                      ----------
and made a part hereof. All capitalized terms used which are not specifically
defined shall have meanings provided in Article 9 of the UCC in effect on the
date hereof to the extent the same are used or defined therein. Unless otherwise
specified herein or in Appendix A, any agreement or contract referred to herein
                       ----------
or in Appendix A shall mean such agreement as modified, amended or supplemented
      ----------
from time to time. Unless otherwise specified, as used in the Loan Documents or
in any certificate, report, instrument or other document made or delivered
pursuant to any of the Loan Documents, all accounting terms not defined in
Appendix A elsewhere in this Agreement shall have the meanings given to such
----------
terms in and shall be interpreted in accordance with GAAP.

II.  ADVANCES, PAYMENT AND INTEREST

     2.1 The Revolving Facility

          (a) Subject to the provisions of this Agreement, Lender shall make
Advances to Borrower under the Revolving Facility from time to time during the
Term; provided that, notwithstanding any other provision of this Agreement, the
      -------------
aggregate amount of all Advances at any one time outstanding under the Revolving
Facility shall not exceed either of (a) the Facility Cap and (b) the
Availability as defined below. The Revolving Facility is a revolving credit
facility, which may be drawn, repaid and redrawn, from time to time as permitted
under this Agreement. Unless otherwise permitted by Lender, each Advance shall
be in an amount of at least $1,000. Subject to the provisions of this Agreement,
Borrower may request Advances under the Revolving Facility up to and including
the value, in dollars, of fifty percent (50%) of the Borrowing Base minus, if
applicable, amounts reserved pursuant

<PAGE>

to this Agreement (such calculated amount being referred to herein as the
"Availability"). Advances under the Revolving Facility automatically shall be
made for the payment of interest on the Note and other Obligations on the date
when due to the extent available and as provided for herein.

          (b) Lender has established the above-referenced advance rate for
Availability and, in its sole credit judgment, may further adjust the
Availability and such advance rate by applying percentages (known as "liquidity
factors") to Eligible Receivables based upon Borrower's actual recent collection
history in a manner consistent with Lender's generally applicable underwriting
practices and procedures, including without limitation Lender's review and
analysis of, among other things, Borrower's historical returns, rebates,
discounts, credits and allowances (collectively, the "Dilution Items"). Such
liquidity factors and the advance rate for Availability may be adjusted by
Lender throughout the Term as warranted in Lender's sole credit judgment,
consistent with Lender's generally applicable underwriting practices and
procedures. Also, Lender shall have the right to establish from time to time, in
its sole credit judgment, consistent with its generally applicable lending
practices, reserves against the Borrowing Base, which reserves shall have the
effect of reducing the amounts otherwise eligible to be disbursed to Borrower
under the Revolving Facility pursuant to this Agreement.

     2.2  The Note; Maturity

          (a) All Advances under the Revolving Facility shall be evidenced by
the Note, evidencing the aggregate indebtedness of Borrower to Lender resulting
from Advances under the Revolving Facility, from time to time. Lender hereby is
authorized, but is not obligated, to enter the amount of each Advance under the
Revolving Facility and the amount of each payment or prepayment of principal or
interest thereon in the appropriate spaces on the reverse of or on an attachment
to the Note. Lender will account to Borrower monthly with a statement of
Advances under the Revolving Facility and charges and payments made pursuant to
this Agreement, and in the absence of manifest error, such accounting rendered
by Lender shall be deemed final, binding and conclusive unless Lender is
notified by Borrower in writing to the contrary within thirty (30) calendar days
of Receipt of each accounting, which notice shall be deemed an objection only to
items specifically objected to therein.

          (b) All amounts outstanding under the Note and other Obligations shall
be due and payable in full, if not earlier in accordance with this Agreement, on
the earlier of (i) the occurrence of an Event of Default if required pursuant
hereto or Lender's demand upon an Event of Default, and (ii) the last day of the
Term (such earlier date being the "Maturity Date").

     2.3  Interest

          Interest on outstanding Advances under the Note shall be payable
monthly in arrears on the first Business Day of each calendar month at an annual
rate of Prime Rate plus 2.0%, provided, however, that, notwithstanding any
                              --------  -------
provision of any Loan Document, the interest on outstanding Advances under the
Note shall be not less than 7.5%, in each case calculated on the basis of a
360-day year and for the actual number of calendar days elapsed in each interest
calculation period. Interest accrued on each Advance under the Note shall be due
and payable on the first day of each calendar month, in accordance with the
procedures provided for herein, commencing the month immediately following the
first Advance, and continuing until the later of the expiration of the Term and
the full performance and irrevocable payment in full in cash of the Obligations
and termination of this Agreement.

     2.4  Revolving Facility Disbursements; Requirement to Deliver Borrowing
          Certificate

                                       2

<PAGE>

          So long as no Default or Event of Default shall have occurred and be
continuing, Borrower may give Lender irrevocable written notice requesting an
Advance under the Revolving Facility by delivering to Lender not later than
11:00 a.m. (New York City time) at least two but not more than four Business
Days before the proposed borrowing date of such requested Advance (the
"Borrowing Date"), a completed Borrowing Certificate and relevant supporting
documentation reasonably satisfactory to Lender, which shall (i) specify the
proposed Borrowing Date of such Advance which shall be a Business Day, (ii)
specify the principal amount of such requested Advance, and (iii) certify the
matters contained in Section 4.2. Each time a request for an Advance is made,
                     ------------
and, in any event and regardless of whether an Advance is being requested, on
the last Business Day of each month during the Term (and more frequently if
Lender shall so request) until the Obligations are indefeasibly paid in cash in
full and this Agreement is terminated, Borrower shall deliver to Lender a
Borrowing Certificate as of the immediately preceeding month end accompanied by
a separate detailed aging and categorizing of Borrower's accounts receivable and
accounts payable and such other supporting documentation with respect to the
figures and information in the Borrowing Certificate as Lender shall reasonably
request from a credit or security perspective or otherwise. On each Borrowing
Date, Borrower irrevocably authorizes Lender to disburse the proceeds of the
requested Advance to Borrower's account(s) as set forth on Schedule 2.4, in all
                                                           ------------
cases for credit to Borrower (or to such other account as to which Borrower
shall instruct Lender) via Federal funds wire transfer no later than 4:00 p.m.
(New York City time).

     2.5  Revolving Facility Collections; Repayment; Borrowing Availability and
          Lockbox

          Each Borrower shall maintain one or more lockbox accounts
(individually and collectively, the "Lockbox Account") with one or more banks
reasonably acceptable to Lender (each, a "Lockbox Bank"), and shall execute with
each Lockbox Bank one or more agreements reasonably acceptable to Lender
(individually and collectively, the "Lockbox Agreement"), and such other
agreements related thereto as Lender may reasonably require to perfect a
security interest therein. Borrower shall ensure that all collections of its
Accounts and all other cash payments received by Borrower are paid and delivered
directly from Account Debtors and other Persons into the appropriate Lockbox
Account. The Lockbox Agreements shall provide that the Lockbox Banks immediately
will transfer all funds paid into the Lockbox Accounts into a depository account
or accounts maintained by Lender or an Affiliate of Lender at such bank as
Lender may communicate to Borrower from time to time (the "Concentration
Account") or such other account as directed by Borrower in accordance with the
terms and conditions of the Lockbox Agreement. Notwithstanding and without
limiting any other provision of any Loan Document, Lender shall apply, on a
daily basis, all funds transferred into the Concentration Account pursuant to
the Lockbox Agreement and this Section 2.5 in such order and manner as
                               -----------
determined by Lender. To the extent that any Accounts collections of Borrower or
any other cash payments received by Borrower are not sent directly to the
appropriate Lockbox Account but are received by Borrower or any of their
Affiliates, such collections and proceeds shall be held in trust for the benefit
of Lender and immediately remitted (and in any event within two (2) Business
Days), in the form received, to the appropriate Lockbox Account for immediate
transfer to the Concentration Account. Borrower acknowledges and agrees that
compliance with the terms of this Section 2.5 is an essential term of this
                                  -----------
Agreement. All funds transferred to the Concentration Account for application to
the Obligations under the Revolving Facility shall be applied to reduce the
Obligations under the Revolving Facility, but, for purposes of calculating
interest hereunder, shall be subject to a seven Business Day clearance period.
If as the result of collections of Accounts and/or any other cash payments
received by Borrower pursuant to this Section 2.5 a credit balance exists with
                                      -----------
respect to the Concentration Account, such credit balance shall be immediately,
and in any event within two (2) Business Days, transferred to an account
designated by Borrower from time to time; provided that each such transfer will
                                          --------
not occur unless and until the credit balance is at least $5,000. If applicable,
at any time prior to the execution of

                                       3

<PAGE>

all or any of the Lockbox Agreements and operation of all or any of the Lockbox
Accounts, Borrower and their Affiliates shall direct all collections or proceeds
it receives on Accounts or from other Collateral to the accounts(s) and in the
manner specified by Lender in its reasonable discretion.

     2.6  Manner of Payment

          Any payments made by Borrower (other than payments automatically paid
through Advances under the Revolving Facility as provided herein), shall be made
only by wire transfer on the date when due, without offset or counterclaim, in
Dollars, in immediately available funds to such account as may be indicated in
writing by Lender to Borrower from time to time. Any such payment received after
2:00 p.m. (New York City time) on the date when due shall be deemed received on
the following Business Day. Whenever any payment hereunder shall be stated to be
due or shall become due and payable on a day other than a Business Day, the due
date thereof shall be extended to, and such payment shall be made on, the next
succeeding Business Day, and such extension of time in such case shall be
included in the computation of payment of any interest (at the interest rate
then in effect during such extension) and/or fees, as the case may be.

     2.7  Repayment of Excess Advances

          Any balance of Advances under the Revolving Facility outstanding at
any time in excess of the lesser of the Facility Cap or the Availability shall
be immediately due and payable by Borrower without the necessity of any demand,
at the Payment Office, whether or not a Default or Event of Default has occurred
or is continuing and shall be paid in the manner specified in Section 2.8.
                                                              ------------

     2.8  Payments by Lender

          Should any amount required to be paid under any Loan Document be
unpaid for more than three (3) Business Days after the due date, such amount may
be paid by Lender, which payment shall be deemed a request for an Advance under
the Revolving Facility as of the date such payment is due, and Borrower
irrevocably authorizes disbursement of any such funds to Lender by way of direct
payment of the relevant amount, interest or Obligations. No payment or
prepayment of any amount by Lender or any other Person shall entitle any Person
to be subrogated to the rights of Lender under any Loan Document unless and
until the Obligations have been fully performed and paid irrevocably in cash and
this Agreement has been terminated. Any sums reasonably expended by Lender as a
result of Borrower's failure to pay, perform or comply with any Loan Document or
any of the Obligations may be charged to Borrower's account as an Advance under
the Revolving Facility and added to the Obligations.

     2.9  Grant of Security Interest; Collateral

          (a) To secure the payment and performance of the Obligations, Borrower
hereby grants to Lender a continuing first priority security interest (subject
to Permitted Liens, which in no case shall include or permit liens on Accounts
or proceeds thereof) in and Lien upon, and pledges to Lender, all of its right,
title and interest in and to the following (collectively and each individually,
the "Collateral"); provided, however, that the Collateral shall not include any
                   --------  -------
of the following to the extent the following relates to, and is utilized solely
in connection with, the contractual arrangements between Borrower and Sepracor,
Inc.:

                                       4

<PAGE>

               (i) all of such Borrower's tangible personal property now owned
or hereafter acquired, other than Inventory and Equipment;

               (ii) all of such Borrower's intangible personal property,
including without limitation all present and future Accounts, securities,
contract rights, Permits, General Intangibles, Chattel Paper, Documents,
Instruments and Deposit Accounts, rights to the payment of money or other forms
of consideration of any kind, tax refunds, insurance proceeds, now owned or
hereafter acquired, and all intangible and tangible personal property relating
to or arising out of any of the foregoing; and

               (iii) any and all additions to any of the foregoing, and any and
all replacements, products and proceeds (including insurance proceeds) of any of
the foregoing.

          (b) Notwithstanding the foregoing provisions of this Section 2.9, such
                                                               -----------
grant of a security interest shall not extend to, and the term "Collateral"
shall not include, any General Intangibles of Borrower to the extent that (i)
such General Intangibles are not assignable or capable of being encumbered as a
matter of law or under the terms of any license or other agreement applicable
thereto (but solely to the extent that any such restriction shall be enforceable
under applicable law) without the consent of the licensor thereof or other
applicable party thereto, and (ii) such consent has not been obtained; provided,
                                                                       --------
however, that the foregoing grant of a security interest shall extend to, and
-------
the term "Collateral" shall include, each of the following: (a) any General
Intangible which is in the nature of an Account or a right to the payment of
money or a proceed of, or otherwise related to the enforcement or collection of,
any Account or right to the payment of money, or goods which are the subject of
any Account or right to the payment of money, (b) any and all proceeds of any
General Intangible that is otherwise excluded to the extent that the assignment,
pledge or encumbrance of such proceeds is not so restricted, and (c) upon
obtaining the consent of any such licensor or other applicable party with
respect to any such otherwise excluded General Intangible, such General
Intangible as well as any and all proceeds thereof that might theretofore have
been excluded from such grant of a security interest and from the term
"Collateral."

          (c) Upon the execution and delivery of this Agreement, and upon the
proper filing of the necessary financing statements, without any further action,
Lender will have a good, valid first priority (subject to Permitted Liens, which
in no case shall include or permit liens on Accounts or the proceeds thereof)
Lien and security interest in the Collateral, subject to no transfer or other
restrictions or Liens of any kind in favor of any other Person except for
Permitted Liens. No financing statement relating to any of the Collateral is on
file in any public office except those (i) on behalf of Lender, and/or (ii) in
connection with Permitted Liens.

     2.10 Collateral Administration

          (a) All Collateral (except Deposit Accounts) will at all times be kept
by Borrower at the locations set forth on Schedule 5.18B hereto and shall not,
                                          --------------
without thirty (30) calendar days prior written notice to Lender, be moved
therefrom, and in any case shall not be moved outside the United States.

          (b) Borrower shall keep commercially reasonable accurate and complete
records of its Accounts and all payments and collections thereon and shall
submit such records to Lender on such periodic bases as may reasonably request
(but unless an Event of Default has occurred and is continuing, not more
frequently than monthly). In addition, if (i) Accounts of Borrower in an
aggregate face amount in excess of $40,000 become ineligible because they fall
within one of the specified categories of ineligibility set forth in the
definition of Eligible Receivables and (ii) Borrower has borrowed fifty percent
(50%) or more of its Availability and such amount is currently outstanding, then
Borrower shall

                                       5

<PAGE>

notify Lender of such occurrence on the first Business Day following Borrower's
knowledge thereof and the Borrowing Base shall thereupon be adjusted to reflect
such occurrence. If requested by Lender after the occurrence and during the
continuance of an Event of Default, Borrower shall execute and deliver to Lender
formal written assignments of all of its Accounts weekly or daily as Lender may
request, including all Accounts created since the date of the last assignment,
together with copies of claims, invoices and/or other information related
thereto. To the extent that collections from such assigned accounts exceed the
amount of the Obligations, such excess amount shall not accrue interest in favor
of Borrower, but shall be available to Borrower upon Borrower's written request.

          (c) Whether or not an Event of Default has occurred, any of Lender's
officers, employees, representatives or agents shall have the right, at any time
during normal business hours, in the name of Lender, any designee of Lender or
Borrower, to verify the validity, amount or any other matter relating to any
Accounts of Borrower which, prior to the occurrence or continuation of a Default
or Event of Default shall not include the right to contact Borrower's customers
or account debtors. Borrower shall cooperate fully with Lender in an effort to
facilitate and promptly conclude such verification process.

          (d) Lender shall have the right at all times after the occurrence and
during the continuance of an Event of Default to notify Account Debtors owing
Accounts to Borrower that their Accounts have been assigned to Lender and to
collect such Accounts directly in its own name and to charge collection costs
and expenses, including reasonable attorney's fees, to Borrower.

          (e) As and when determined by Lender in its sole discretion, Lender
will perform the searches described in clauses (i) and (ii) below against
Borrower (the results of which are to be consistent with Borrower's
representations and warranties under this Agreement) once per calendar quarter
prior to the occurrence and continuation of any Default or Event of Default at
Borrower's expense, and following the occurrence and continuation of a Default
or Event of Default, as often as Lender reasonably shall deem appropriate, all

Account, Lender, as the irrevocably made, constituted and appointed true and
lawful attorney for Borrower pursuant to this paragraph, may, upon the

III. FEES AND OTHER CHARGES; ALLOCATION OF PURCHASE PRICE

          Borrower shall pay to Lender an unused line fee (the "Unused Line
Fee") in an amount equal to 0.042% (per month, prorated for partial months where
this Agreement is only effective for a portion of any such month) of the
difference derived by subtracting (i) the daily average amount of the balances
under the Revolving Facility outstanding during the preceding month, from (ii)
the Facility Cap. The Unused Line Fee shall be payable monthly in arrears on the

     3.4  Early Termination Fees

          If (i) Borrower terminates the Revolving Facility under Section 11.1
                                                                  ------------
hereof, (ii) Lender demands or Borrower is otherwise required to make payment in
full of the Revolving Facility and/or Obligations relating to the Revolving
Facility upon the occurrence of an Event of Default, (iii) a voluntary or
involuntary Change of Control occurs, (iv) any prepayment of the Revolving
Facility and/or Obligations occurs (other than reductions to zero of the
outstanding balance of the Revolving Facility resulting from the ordinary course
operation of the provisions of Section 2.5), whether by virtue of Lender's
                               -----------
exercising its right of set-off or otherwise, or (v) any acceleration of the
Obligations or cessation of lending and termination of the commitment to lend
occurs as a result of or during a bankruptcy, reorganization or other proceeding
or liquidation or pursuant to any Debtor Relief Law (a "termination"), then, at
the effective date of any such termination, Borrower shall pay Lender (in
addition to the then outstanding principal, accrued interest and other
Obligations relating to the Revolving Facility pursuant to the terms of this
Agreement and any other Loan Document), as yield

                                       7

          All fees hereunder shall be computed on the basis of a year of 360

applicable. In no contingency or event whatsoever, whether by reason of
acceleration or otherwise, shall the interest and other charges paid or agreed
to be paid to Lender for the use, forbearance or detention of money hereunder
exceed the maximum rate permissible under applicable law which a court of
competent jurisdiction shall, in a final determination, deem applicable hereto.
If, due to any circumstance whatsoever, fulfillment of any provision hereof, at
the time performance of such provision shall be due, shall exceed any such
limit, then, the obligation to be so fulfilled shall be reduced to such lawful
limit, and, if Lender shall have received interest or any other charges of any
kind which might be deemed to be interest under applicable law in excess of the
maximum lawful rate, then such excess shall be applied first to any unpaid fees
and charges hereunder, then to unpaid principal balance owed by Borrower
hereunder, and if the then remaining excess interest is greater than the
previously unpaid principal balance, Lender shall promptly refund such excess
amount to Borrower and the provisions hereof shall be deemed amended to provide
for such permissible rate. The terms and provisions of this Section 3.5 shall
                                                            -----------
control to the extent any other provision of any Loan Document is inconsistent
herewith.

          Upon the occurrence and during the continuation of an Event of

the Obligations shall be increased by 3.0% per annum (the "Default Rate").

income. If Borrower shall be required by law to deduct any such amounts from or

local taxing authorities with respect to interest or commitment fees or other
fees payable hereunder or changes in the rate of tax on the overall net income
of Lender), or (B) imposes on Lender any other condition or increased cost in
connection with the transactions contemplated thereby or participations therein;
and the result of any of the foregoing is to increase the cost to Lender of
making or continuing any Loan hereunder or to reduce any amount receivable
hereunder, then, in any such case, Borrower shall promptly pay to Lender any
additional amounts necessary to compensate Lender, on an after-tax basis, for
such additional cost or reduced amount as determined by Lender. If Lender
becomes entitled to claim any additional amounts pursuant to this Section 6.14
                                                                  ------------
it shall promptly notify Borrower of the event by reason of which Lender has
become so entitled, and each such notice of additional amounts payable pursuant
to this Section 6.14 submitted by Lender to Borrower shall, absent manifest
        ------------

being limited by any other provision of any Loan Document, Borrower at all times
shall retain and use a Person acceptable to Lender to process, manage and pay
its payroll taxes and shall cause to be delivered to Lender, within ten (10)
calendar days after such Person provides Borrower with a report and evidence of
payment of such payroll taxes (which Borrower shall require such Person to
deliver no less often than once per quarter), a copy of such report and related
evidence.

          (a) In addition to the acceleration provisions set forth in Article
                                                                      -------
VIII above, upon the occurrence and continuation of an Event of Default, Lender
----
shall have the right to exercise any and all rights, options and remedies
provided for in any Loan Document, under the UCC or at law or in equity,
including, without limitation, the right to (i) apply any property of Borrower
held by Lender to reduce the Obligations, (ii) foreclose the Liens created under
the Security Documents, (iii) realize upon, take possession of and/or sell any
Collateral or securities pledged with or without judicial process, (iv) exercise
all rights and powers with respect to the Collateral as Borrower, as applicable,
might exercise, (v) collect and send notices regarding the Collateral, with or
without judicial process, (vi) by its own means or with judicial assistance,

or other sums, and no Borrower shall resist or interfere with such action, (vii)
at Borrower's expense, require that all or any part of the Collateral be
assembled and made available to Lender at any place designated by Lender, (viii)
reduce or otherwise change the Facility Cap, and/or (ix) relinquish or abandon

prior notice, to the extent Borrower is required to do so or act hereunder, to:
(i) obtain insurance covering any of the Collateral; (ii) pay for the
performance of any of Obligations; (iii) discharge taxes or Liens on any of the
Collateral that are in violation of any Loan document unless Borrower is in good

(iv) pay for the maintenance and preservation of the Collateral. Such expenses
and advances shall be added to the Obligations until reimbursed to Lender and
shall be secured by the Collateral, and such payments by Lender shall not be

remedies of Lender.

          (b) Borrower agrees that notice received by it at least ten (10)
calendar days before the time of any intended public sale, or the time after

be deemed to be reasonable notice of such sale or other disposition. If
permitted by applicable law, any perishable Collateral which threatens to
speedily decline in value or which is sold on a recognized market may be sold
immediately by Lender without prior notice to Borrower. At any sale or
disposition of Collateral or securities pledged, Lender may (to the extent
permitted by applicable law) purchase all or any part thereof free from any
right of redemption by Borrower which right is hereby waived and released.
Debtor covenants and agrees not to interfere with or impose any obstacle to
Secured Party's exercise of its rights and remedies under the UCC with respect
to the Collateral. Lender, in dealing with or disposing of the Collateral or any
part thereof, shall not be required to give priority or preference to any item

expenses, liabilities and advances made or incurred in connection therewith);
(ii) second, to the payment of all Obligations as provided herein; (iii) third,
     ------                                                              -----
to the satisfaction of Indebtedness secured by any subordinate security interest
of record in the Collateral if written notification of demand therefor is
received before distribution of the proceeds is completed, provided, that, if
                                                           --------
requested by Lender, the holder of a subordinate security interest shall furnish
reasonable proof of its interest, and unless it does so, Lender need not address
its claims; and (iv) fourth, to the payment of any surplus then remaining to
                     ------
Borrower, unless otherwise provided by law or directed by a court of competent
jurisdiction, provided that Borrower shall be liable for any deficiency if such
              --------
proceeds are insufficient to satisfy the Obligations or any of the other items
referred to in this section.

     9.3  Rights of Lender to Appoint Receiver

          Without limiting and in addition to any other rights, options and
remedies Lender has under the Loan Documents, the UCC, at law or in equity, upon
the occurrence and continuation of an Event of Default, Lender shall have the
right to apply for and have a receiver appointed by a court of competent
jurisdiction in any action taken by Lender to enforce its rights and remedies in
order to manage, protect and preserve the Collateral and continue the operation
of the business of Borrower and to collect all revenues and profits thereof and
apply the same to the payment of all expenses and other charges of such
receivership including the compensation of the receiver and to the payments as
aforesaid until a sale or other disposition of such Collateral shall be finally
made and consummated.

     9.4  Rights and Remedies not Exclusive

          Lender shall have the right in its sole discretion to determine which
rights, Liens and/or remedies Lender may at any time pursue, relinquish,
subordinate or modify, and such determination will not in any way modify or
affect any of Lender's rights, Liens or remedies under any Loan Document,
applicable law or equity. The enumeration of any rights and remedies in any Loan
Document is not intended to be exhaustive, and all rights and remedies of Lender
described in any Loan Document are cumulative and are not alternative to or
exclusive of any other rights or remedies which Lender otherwise may have. The
partial or complete exercise of any right or remedy shall not preclude any other
further exercise of such or any other right or remedy.

X. WAIVERS AND JUDICIAL PROCEEDINGS

          Except as expressly provided for herein, Borrower hereby waives
demand, presentment, protest and all defenses with respect to any and all

provision or affect the liability of Borrower or preclude any other or further
exercise of such

                                       28

defaults by any other party in the performance of any of the provisions of any

          The Loan Documents shall be governed by and construed in accordance
with the internal laws of the State of Maryland without giving effect to its
choice of law provisions. Any judicial proceeding against Borrower with respect
to the Obligations, any Loan Document or any related agreement may be brought in
any federal or state court of competent jurisdiction located in the State of
Maryland. By execution and delivery of each Loan Document to which it is a
party, Borrower (i) accepts the non-exclusive jurisdiction of the aforesaid
courts and irrevocably agrees to be bound by any judgment rendered thereby, (ii)
waives personal service of process, (iii) agrees that service of process upon it
may be made by certified or registered mail, return receipt requested, pursuant
to Section 12.5 hereof, and (iv) waives any objection to jurisdiction and venue
   ------------
of any action instituted hereunder and agrees not to assert any defense based on
lack of jurisdiction, venue or convenience. Nothing shall affect the right of
Lender to serve process in any manner permitted by law or shall limit the right
of Lender to bring proceedings against Borrower in the courts of any other
jurisdiction having jurisdiction. Any judicial proceedings against Lender
involving, directly or indirectly, the Obligations, any Loan Document or any
related agreement shall be brought only in a federal or state court located in
the State of Maryland or the State of Delaware. All parties acknowledge that
they participated in the negotiation and drafting of this Agreement and that,
accordingly, no party shall move or petition a court construing this Agreement
to construe it more stringently against one party than against any other.

     12.2 Successors and Assigns; Participations; New Lenders

          The Loan Documents shall inure to the benefit of Lender, Transferees
and all future holders of any Note, the Obligations and/or any of the
Collateral, and each of their respective successors and assigns. Each Loan
Document shall be binding upon the Persons' other than Lender that are parties
thereto and their respective successors and assigns, and no such Person may
assign, delegate or transfer any Loan Document or any of its rights or
obligations thereunder without the prior written consent of Lender. No rights
are intended to be created under any Loan Document for the benefit of any third
party donee, creditor or incidental beneficiary of Borrower. Nothing contained
in any Loan Document shall be construed as a delegation to Lender of any other
Person's duty of performance. BORROWER ACKNOWLEDGES AND AGREES THAT LENDER AT
ANY TIME AND FROM TIME TO TIME MAY (I) DIVIDE AND RESTATE ANY NOTE, AND/OR (II)
sell, assign or GRANT PARTICIPATING INTERESTS IN OR TRANSFER ALL OR ANY PART OF
ITS RIGHTS OR OBLIGATIONS UNDER ANY LOAN DOCUMENT, NOTE, THE OBLIGATIONS AND/OR
THE COLLATERAL TO OTHER PERSONS (EACH SUCH TRANSFEREE, ASSIGNEE OR PURCHASER, A
"TRANSFEREE"), provided that all such assignments or transfers shall be in
               -------- ----
minimum amount of $500,000 or, if less, Lender's entire interest under the Loan
Documents and, provided further, that any such transfer by Lender shall not be
               -------- -------
to a Person known by Lender to be a competitor of Borrower. Each Transferee
shall have all of the rights and benefits with respect to the Obligations,
Notes, Collateral and/or Loan Documents held by it as fully as if the original
holder thereof, and either Lender or any Transferee may be designated as the
sole agent to manage the transactions and obligations contemplated

                                       30

<PAGE>

therein; provided that, notwithstanding anything to the contrary in any Loan
         -------- ----
Document, Borrower shall not be obligated to pay under this Agreement to any
Transferee any sum in excess of the sum which Borrower would have been obligated
to pay to Lender had such participation not been effected. Notwithstanding any
other provision of any Loan Document, Lender may disclose to any Transferee all
information, reports, financial statements, certificates and documents obtained
under any provision of any Loan Document.

     12.3 Application of Payments

          To the extent that any payment made or received with respect to the
Obligations is subsequently invalidated, determined to be fraudulent or
preferential, set aside or required to be repaid to a trustee, debtor in
possession, receiver, custodian or any other Person under any Debtor Relief Law,
common law or equitable cause or any other law, then the Obligations intended to
be satisfied by such payment shall be revived and shall continue as if such
payment had not been received by Lender. Any payments with respect to the
Obligations received shall be credited and applied in such manner and order as
Lender shall decide in its sole discretion.

     12.4 Indemnity

          Borrower shall indemnify Lender, its Affiliates and its and their
respective managers, members, officers, employees, Affiliates, agents,
representatives, successors, assigns, accountants and attorneys (collectively,
the "Indemnified Persons") from and against any and all liabilities,
obligations, losses, damages, penalties, actions, judgments, suits, costs,
expenses and disbursements of any kind or nature whatsoever (including, without
limitation, reasonable fees and disbursements of counsel and in-house
documentation and diligence fees and legal expenses) which may be imposed on,
incurred by or asserted against any Indemnified Person other than Borrower with
respect to or arising out of, or in any litigation, proceeding or investigation
instituted or conducted by any Person with respect to any aspect of, or any
transaction contemplated by or referred to in, or any matter related to, any
Loan Document or any agreement, document or transaction contemplated thereby,
whether or not such Indemnified Person is a party thereto, except to the extent
that any of the foregoing arises out of the gross negligence or willful
misconduct of such Indemnified Person or a claim of Borrower finally determined
by a court of competent jurisdiction in favor of Borrower. If any Indemnified
Person uses in-house counsel for any purpose for which Borrower is responsible
to pay or indemnify, Borrower expressly agrees that its indemnification
obligations include reasonable charges for such work commensurate with the fees
that would otherwise be charged by outside legal counsel selected by such
Indemnified Person in its reasonable discretion for the work performed. Lender
agrees to give Borrower reasonable notice of any event of which Lender becomes
aware for which indemnification may be required under this Section 12.4, and
                                                           ------------
Lender may elect (but is not obligated) to direct the defense thereof, provided
that the selection of counsel shall be subject to Borrower's consent, which
consent shall not be unreasonably withheld or delayed. Any Indemnified Person
may, in its reasonable discretion, take such actions as it deems necessary and
appropriate to investigate, defend or, with Borrower's written consent, which
still not be unreasonably withheld, settle any event or take other remedial or
corrective actions with respect thereto as may be necessary for the protection
of such Indemnified Person or the Collateral. Notwithstanding the foregoing, if
any insurer agrees to undertake the defense of an event (an "Insured Event"),
Lender agrees not to exercise its right to select counsel to defend the event if
that would cause Borrower's insurer to deny coverage; provided, however, that
                                                      --------  -------
Lender reserves the right to retain counsel to represent any Indemnified Person
with respect to an Insured Event at its sole cost and expense. To the extent
that Lender obtains recovery from a third party other than an Indemnified Person
of any of the amounts that

                                       31

<PAGE>

Borrower has paid to Lender pursuant to the indemnity set forth in this Section
                                                                        -------
12.4, then Lender shall promptly pay to such Borrower the amount of such
----
recovery.

     12.5 Notice

          Any notice or request under any Loan Document shall be given to any
party to this Agreement at such party's address set forth beneath its signature
on the signature page to this Agreement, or at such other address as such party
may hereafter specify in a notice given in the manner required under this
Section 12.5. Any notice or request hereunder shall be given only by, and shall
------------
be deemed to have been received upon (each, a "Receipt"): (i) registered or
certified mail, return receipt requested, on the date on which such received as
indicated in such return receipt, (ii) delivery by a nationally recognized
overnight courier, one (1) Business Day after deposit with such courier, or
(iii) facsimile or electronic transmission, in each case upon telephone or
further electronic communication from the recipient acknowledging receipt
(whether automatic or manual from recipient), as applicable.

     12.6 Severability; Captions; Counterparts; Facsimile Signatures

          If any provision of any Loan Document is adjudicated to be invalid
under applicable laws or regulations, such provision shall be inapplicable to
the extent of such invalidity without affecting the validity or enforceability
of the remainder of the Loan Documents which shall be given effect so far as
possible. The captions in the Loan Documents are intended for convenience and
reference only and shall not affect the meaning or interpretation of the Loan
Documents. The Loan Documents may be executed in one or more counterparts (which
taken together, as applicable, shall constitute one and the same instrument) and
by facsimile transmission, which facsimile signatures shall be considered
original executed counterparts. Each party to this Agreement agrees that it will
be bound by its own facsimile signature and that it accepts the facsimile
signature of each other party.

     12.7 Expenses

          Borrower shall pay, whether or not the Closing occurs, all costs and
expenses incurred by Lender and/or its Affiliates, including, without
limitation, documentation and diligence fees and expenses, all search, audit,
appraisal, recording, professional and filing fees and expenses and all other
out-of-pocket charges and expenses (including, without limitation, UCC and
judgment and tax lien searches and UCC filings and fees for post-Closing UCC and
judgment and tax lien searches and wire transfer fees and audit expenses), and
reasonable attorneys' fees and expenses, (i) in any effort to enforce, protect
or collect payment of any Obligation or to enforce any Loan Document or any
related agreement, document or instrument, (ii) in connection with entering
into, negotiating, preparing, reviewing and executing the Loan Documents and/or
any related agreements, documents or instruments (which shall not exceed $50,000
without Lender's prior notice to Borrower, (iii) arising in any way out of
administration of the Obligations, (iv) in connection with instituting,
maintaining, preserving, enforcing and/or foreclosing on Lender's Liens in any
of the Collateral or securities pledged under the Loan Documents, whether
through judicial proceedings or otherwise, (v) in defending or prosecuting any
actions, claims or proceedings arising out of or relating to Lender's
transactions with Borrower, (vi) in seeking, obtaining or receiving any advice
with respect to its rights and obligations under any Loan Document and any
related agreement, document or instrument, and/or (vii) in connection with any
modification, restatement, supplement, amendment, waiver or extension of any
Loan Document and/or any related agreement, document or instrument. To the
extent incurred hereunder and not reimbursed promptly, all of the foregoing
shall be charged to Borrower's account and shall be part of the Obligations. If
Lender or any of its Affiliates uses in-house counsel for any purpose under any
Loan Document for which Borrower is responsible to pay or indemnify, Borrower
expressly agrees that its

                                       32

<PAGE>

Obligations include reasonable charges for such work commensurate with the fees
that would otherwise be charged by outside legal counsel selected by Lender or
such Affiliate in its sole discretion for the work performed. Without limiting
the foregoing, Borrower shall pay all taxes (other than taxes based upon or
measured by Lender's income, franchise taxes in lieu thereof, or revenues or any
personal property tax), if any, in connection with the issuance of any Note and
the filing and/or recording of any documents and/or financing statements.

     12.8 Entire Agreement

          This Agreement and the other Loan Documents to which Borrower is a
party constitute the entire agreement between Borrower and Lender with respect
to the subject matter hereof and thereof, and supersede all prior agreements and
understandings, if any, relating to the subject matter hereof or thereof. Any
promises, representations, warranties or guarantees not herein contained and
hereinafter made shall have no force and effect unless in writing signed by
Borrower and Lender. No provision of this Agreement may be changed, modified,
amended, restated, waived, supplemented, discharged, canceled or terminated
orally or by any course of dealing or in any other manner other than by an
agreement in writing signed by Lender and Borrower. Each party hereto
acknowledges that it has been advised by counsel in connection with the
negotiation and execution of this Agreement and is not relying upon oral
representations or statements inconsistent with the terms and provisions hereof.

     12.9 Lender Approvals

          Unless expressly provided herein to the contrary, any approval,
consent, waiver or satisfaction of Lender with respect to any matter that is
subject of any Loan Document may be granted or withheld by Lender in its sole
and absolute discretion.

     12.10 Confidentiality and Publicity

          (a) Borrower agrees, and agrees to cause each of its Affiliates, (i)
not to transmit or disclose any provision of any Loan Document to any Person
(other than to Borrower's advisors and officers on a need-to-know basis) without
Lender's prior written consent, (ii) to inform all Persons of the confidential
nature of the Loan Documents and to direct them not to disclose the same to any
other Person and to require each of them to be bound by these provisions. Lender
reserves the right to review and approve all materials that Borrower or any of
its Affiliates prepares that contain Lender's name or describe or refer to any
Loan Document, any of the terms thereof or any of the transactions contemplated
thereby. Borrower shall not, and shall not permit any of its Affiliates to, use
Lender's name (or the name of any of Lender's Affiliates) in connection with any
of its business operations. Nothing in this paragraph shall condition or limit
Borrower's ability to disclose the Loan Documents in any filing with a
governmental agency or in connection with its financial statements. Nothing
contained in any Loan Document is intended to permit or authorize Borrower or
any of its Affiliates to contract on behalf of Lender.

          (b) Lender agrees to keep confidential during the Term any material or
information about Borrower that was delivered, disclosed, furnished or provided
by Borrower or any agent, attorney or accountant of Borrower to Lender and that
was identified by Borrower or such other Person in writing as confidential (the
"Confidential Information"). Confidential Information excludes material or
information that is or becomes generally available to the public or to any third
party (other than Lender and its Representatives) than as a result of a breach
by Lender hereof, or that was within the knowledge or possession of Lender or
its Representatives (defined below) prior to being furnished by Borrower or any
agent, attorney or accountant of Borrower to Lender, or was or becomes available
to Lender or its

                                       33

<PAGE>

Representatives from a third party, or that was independently developed by
Lender or its Representatives without reference to the Confidential Information.
Notwithstanding the foregoing or any other provision of this Agreement, Lender
may disclose, provide and/or furnish Confidential Information: (a) to its
officers, directors, partners, members, managers, stockholders, controlling
persons, affiliates, agents, advisors, representatives and employees, and any
potential Transferee of the Loans (each, a "Representative"); and (b) otherwise
pursuant to any of the following: (i) to any other person subject to an
obligation to maintain the confidentiality of such Confidential Information on
substantially similar terms as those in this subsection, or (ii) if required by
any governmental entity, law, regulation, governmental proceeding, court order
or similar process or otherwise, (iii) in connection with enforcing any
agreement or rights between Borrower and Lender or defending any action or
relating to the relationship between Lender and Borrower, and/or (iv) with
respect to public or non-confidential portions of such Confidential Information.
Lender further agrees not to use Borrower's name or logo in any written
publication without Borrower's prior consent, which shall not be unreasonably
withheld or delayed.
