                     be the Appraised Value;

               (iii) If the foregoing two appraisals are not the same and the
                     lower value determined by an appraiser differs by more than
                     one percent of the value determined by the other, then the
                     appraisers shall together select a third appraiser to
                     determine a value;

               (iv)  If the determination of the third appraiser is greater than
                     the largest of the first two appraisals or less than the
                     smallest of the first two appraisals, then the average of

               (v)   If the determination of the third appraiser is between the
                     first two appraisals, then the average of the third
                     appraisal and the closest of the first two appraisals shall
                     be the Appraised Value.

Each party shall pay the fees and costs of the appraiser it selects, and the
fees and costs of the third appraiser, if any, shall be paid equally by Company
and Lender.

               (c) Remedies.  Failure to comply with the terms of the put right 
                   --------    
set forth in this Section 3.03 within 30 days of Lender's demand thereunder
shall entitle Lender to all of the rights and remedies available to Lender under
this Agreement and at law or equity, including, without limitation, the right of
specific performance.

               (d) Financing of Put.  Upon the exercise of the put rights 
                   ----------------        
described in this section, the Company shall pay the Put Price in cash, to the
extent the Company (i) has funds legally available, and (ii) has available cash
or short term investments which may be liquidated. To the extent the Company is
unable to pay the Put Price in cash, Lender will provide financing to the
Company to pay the Put Price through subordinated debt without equity at an
interest rate of 12% and on other commercially reasonable terms. The Company
shall not be required to finance the Put Price by issuing additional equity
securities.

                   (e) Limitation on Exercise of Put.  In no event may Lender 
                       -----------------------------    
exercise its rights hereunder if doing so would cause the Company to violate the
terms of the Bank Loan Agreement, or any successor document, or any similar
agreement entered into by the Company with a lender of Permitted Senior Debt.

          3.04  Personal Gain Upon Sale.  In the event of a Transfer of
                -----------------------                                
Company's Business, then any personal gain relating to such Transfer of
Company's Business and flowing to any officer, director or principal shareholder
of the Company otherwise than through direct payment for their equity ownership
in the Company, or through dividends or return of capital paid in respect
thereof or through severance arrangements entered into prior to commencement of
negotiations with respect to such Transfer, shall be added to the direct
consideration for the sale in calculating the total sale price for purposes of
determining any share thereof which the Lender may be entitled to receive.  Such
personal gain shall include without limitation any salaries or consulting fees
in excess of fair market compensation payable in connection with the Company's
operations after such sale or any points or fees paid to induce such sale.  In
the event of any disputes arising hereunder, the parties shall obtain a fairness
opinion from an investment banker chosen by the parties.  In the event the
parties cannot agree on an investment banker, the Company shall select one
investment banker, Lender shall select one investment banker and the two
investment bankers shall select a third investment banker who shall be retained
to render the fairness opinion.  The Company and Lender shall equally share the
expenses related hereto.

copy of the audited consolidated financial statements summarizing the financial
results of operation of the Company for the fiscal year ending December 31, 1997
provided to Lender by the Company (the "Audited Financials"). The Audited

principles consistently applied, and present fairly, in all material respects,

operations at such dates and for the periods then ended. The auditors have
issued an unqualified statement to the Company concerning the Audited

transactions contemplated by this Agreement, the present fair saleable value of
the Company's assets as a going concern is greater than the amount required to
pay the Company's total indebtedness (contingent or otherwise), and is greater
than the amount that will be required to pay such indebtedness as it matures and
as it becomes absolute and matured.  The transactions contemplated hereby were
effectuated without actual intent to hinder, delay or defraud present or future
creditors of the Company; it is the Company's express intention that it will
maintain a solvent financial condition, giving effect to the debt incurred
hereunder, as long as any of the Obligations remain outstanding or the Company
is obligated to the Lender in any other manner

is a party or by which the Company or any of the Company's assets is bound,
together with all amendments or supplements thereto (collectively, the "Leases")
which list provides with respect to each lease the landlord, commencement date,
rent and termination date.  True and complete copies of each of the Leases have

Company's knowledge, each of the Leases is valid, binding and enforceable in
accordance with its terms and remains in full force and effect.  Except as set
forth on Exhibit 4.13, the Company is not in default or alleged to be in default
         ------------

default or alleged to be in default with the giving of notice, passage of time,
or both), and, to the best of the Company's knowledge, no party other than the
Company is in default with respect to such party's obligations under any of the
Leases (or would be in default or alleged to be in default with the giving of
notice, passage of time, or both).  The Company's possession of any property
leased by it has not been disturbed, nor has any claim been asserted against the
Company that is or could be adverse to the Company's interests under any of the
Leases.  None of the Leases is subject to any rights of set-off, recoupment or
similar deduction or offset.  Except as disclosed on Exhibit 4.13, the Company

Company's interest thereunder.  The Company has previously delivered to Lender

Closing, including financing arrangements with sellers in connection with

and the Economic Impact Assessment signed where required by the Company and

                --------------------------------------                         
does not intend to become, an "investment company", as such term is defined in
the Investment Company Act of 1940, as amended (the "40 Act"), and neither the
Company nor any of its officers, directors, partners or controlling persons is

amended Regulations promulgated under the SBA Act, nor an "affiliated person" of
any Lender, as such term is defined in Section 2(a)(3) of the 40 Act.

          4.26  General Legal Compliance.  To the best of the Company's
                ------------------------                               
knowledge, the Company is not in violation of any Applicable Law that would
apply to it or to its business, the violation of which would have a material
adverse effect on the Company, its business, or its prospects.

          4.27  Environmental Legal Compliance.  Without limiting the generality
                ------------------------------                                  
of the representation and warranty made in Section 4.26 above, to the best of
the Company's knowledge, the Company is not in violation of any applicable
Environmental Law, which violation would have a material adverse effect on the
Company or its business or prospects, and the Company has not been notified of
any action, suit, proceeding or investigation which calls into question
compliance by the Company with any Environmental Laws or which seeks to suspend,
revoke or terminate any license, permit or approval necessary for the
generation, handling, storage, treatment or disposal of any Hazardous Material.
As used in this Agreement, the term "Environmental Law" shall mean,
collectively, the Comprehensive Environmental Response, Compensation, and
Liability Act of 1980, as amended, 42 U.S.C. (S)9601 et seq. ("CERCLA"); the
Solid Waste Disposal Act, as amended, 42 U.S.C. (S)6901 et seq.("SWDA")
including the Resource Conservation and Recovery Act of 1976, as amended, 42
U.S.C. (S)6901 et seq. ("RCRA"); the Clean Water Act, as amended, 42 U.S.C.
(S)1251 et seq.("CWA"); the Clean Air Act, as amended, 42 U.S.C. (S)7401 et
seq.; any "superfund" or "superlien" law; and any other Applicable Law
regulating, relating to, or imposing liability or standards of conduct
concerning, any hazardous, toxic or dangerous waste, substance or material, and
the term "Hazardous Material" shall mean and include any hazardous, toxic or
dangerous waste, substance or material, the generation, handling, storage,
disposal, treatment or emission of which is subject to any Environmental Law.

          4.28  Employee Benefit Matters.  There is no existing single-employer
                ------------------------                                       
plan defined in Section 4021(a) of the Employee Retirement Income Security Act
of 1974, as amended ("ERISA") as to which the Company is, or immediately after
the Closing will be, an 

                                      -15-
<PAGE>
 
"employer" or a "substantial employer" as defined in Sections 3(5) and
4001(a)(2) of ERISA, respectively. Attached hereto as Exhibit 4.28 is an
                                                      ------------
accurate and complete list of each plan described in Section 4021(a) of ERISA,
as to which the Company is assuming any liability or will be liable to make
contributions or for the payment of benefits. The Company has made available to
Lender true and complete copies of each of the plans listed on Exhibit 4.28
                                                               ------------
attached hereto. To the best knowledge of the Company, there have been no
"reportable events" as set forth in Section 4043(b) of ERISA with respect to any
such plan, and no termination of any such plan since the effective date of ERISA
which could result in any tax, penalty or liability being imposed upon the
Company. The Company has not participated in, and the execution and delivery of
this Agreement by the Company will not involve, any "prohibited transaction" (as
defined in Section 4975 of the Internal Revenue Code of 1986, as amended) that
could subject the Company to any tax or penalty imposed by Section 4975 of the
Internal Revenue Code of 1986, as amended. To the best knowledge of the Company,
no predecessor-in-interest to the Company has participated in any "prohibited
transaction" (as defined in Section 4975 of the Internal Revenue Code of 1986,
as amended) that could subject the Company to any tax or penalty imposed by
Section 4975 of the Internal Revenue Code of 1986, as amended. Since the
effective date of ERISA, neither the Company, nor, to the best knowledge of the
Company, any predecessor-in-interest to the Company, has incurred any
"accumulated funding deficiency", as such term is defined in Section 302 of
ERISA, to which the Company could be subject or for which it might be liable.
The Company is not, and immediately after the Closing will not be, a party to,
and none of the operations of the Company is, or after the Closing will be,
covered by, a "multiemployer plan", as defined in Section 3(37) of ERISA.

          4.29  Collective Bargaining.  The Company is not, and after the
                ---------------------                                    
Closing will not be, a party to or subject to any collective bargaining
agreements or union contracts.  There are no labor disputes pending or
threatened against the Company or, to the best knowledge of the Company, between
the Company and its employees which have affected, or so far as the Company can
reasonably foresee may affect, materially and adversely the business or
condition of the Company or the Company's business or prospects.

          4.30  Employees.  Attached hereto as Exhibit 4.30 is an accurate and
                ---------                      ------------                   
complete list of all employment and compensation contracts, including all
retirement benefit agreements not disclosed on Exhibit 4.28, between the Company
                                               ------------                     
and officers and executives of the Company.  The Company has made available to
the Lender accurate and complete copies of all such contracts.  No officer of
the Company has advised the Company (orally or in writing) that he or she
intends to terminate employment with the Company.

          4.31  Brokers.  The Company has no knowledge of any brokerage fees due
                -------                                                         
for the transactions contemplated hereby and will indemnify Lender for any
claims with respect thereto.

          10.06  No Oral Modification or Waivers.  The terms herein may not be
                 -------------------------------

          10.07  Relationship of the Parties; Advice of Counsel.  This Agreement
                 ----------------------------------------------                 
provides for the making of an investment in the form of loans made by Lender, in
its capacity as lender, to the Company, in its capacity as borrower, and for the
payment of interest and repayment of principal by the Company to Lender.  The
provisions herein for compliance with financial covenants and delivery of
financial statements are intended solely for the benefit of Lender to protect
its interest as lender in assuring payments of interest and repayment of
principal, and nothing contained in this Agreement shall be construed as
permitting or obligating Lender to act as financial or business advisor or
consultant to the Company, as permitting or obligating Lender to control the
Company or to conduct the Company's operations, as creating any fiduciary
obligation on the part of Lender to the Company, or as creating any joint
venture, agency or other relationship between the parties other than as
explicitly and specifically stated in this Agreement.  Lender is not (and shall
not be construed as) a partner, joint venturer, alter-ego, manager, controlling
person, operator or other business participant of any kind of the Company;
neither Lender nor the Company intend that Lender assumes such status and,
accordingly, Lender shall not be deemed responsible for (or a participant in)
any acts or omissions of the Company.  The Company and each of the other Loan
Parties each represent and warrant to Lender that they have had the advice of
experienced counsel of their own choosing in connection with the negotiation and
execution of this Agreement and with respect to all matters contained herein.

out of this Agreement or any of the other Loan Documents shall be proper only in
the state or federal courts of the State of Maryland, and all parties to this
Agreement and the other Loan Documents hereby consent to such venue and agree
that it shall not be not inconvenient and not subject to review by any court
other than such courts in Maryland;

                 (b)  The Company and each of the other Loan Parties intend and
agree that the courts of the jurisdictions in which the Company is formed and in

any judgment rendered by a court of the State of Maryland against the Company or
any other Loan Party under this Agreement and the other Loan Documents, and the
Company and each other Loan Party under this Agreement and the other Loan
Documents each intend and agree that such courts should hold that the Maryland

registered mail or by hand-delivering a copy of such process to the Company or
such other Loan Party (as applicable) at its address specified above; and

                 (d)  The Company and each other Loan Party all expressly
acknowledge and agree that the provisions of this Section 10.09 are reasonable
and made for the express benefit of each of the Lenders.

          10.10  Waiver of Trial by Jury.  Each party to this Agreement agrees
                 -----------------------                                      
that any suit, action or proceeding, whether claim, defense or counterclaim,
brought or instituted by any party hereto or any successor or assign of any
party on or with respect to this Agreement or any other Loan Document or which
in any way relates, directly or indirectly, to the Note or any event,
transaction or occurrence arising out of or in any way connected with this
Agreement, the other Loan Documents or the dealings of the parties with respect
thereto, shall be tried only by a court and not by a jury.  EACH PARTY HEREBY
EXPRESSLY WAIVES ANY RIGHT TO A TRIAL BY JURY IN ANY SUCH SUIT, ACTION OR
PROCEEDING, AND ACKNOWLEDGES THAT THIS IS A WAIVER OF A LEGAL RIGHT AND THAT IT
MAKES THIS WAIVER VOLUNTARILY AND KNOWINGLY AFTER CONSULTATION WITH, OR THE
OPPORTUNITY TO CONSULT WITH, COUNSEL OF ITS CHOICE.

          10.11  Costs and Fees Related to Enforcement or a Successful Defense.
                 -------------------------------------------------------------
