only in accordance with the terms and conditions of such Rule and, further,
that in case such Rule is not applicable to any sale of Holdco Preferred
Shares, FCG Preferred Shares, Holdco Warrants and FCG Warrants, as applicable,
resale thereof may require compliance with some other exemption under the
Securities Act prior to resale. Holdco and FCG have informed the Investor that
certificates representing the Holdco Preferred Shares, FCG Preferred Shares,
Holdco Warrants and FCG Warrants issued pursuant to this Agreement bear the
following legend:

of such earlier date), (2) where the failure of any representations and

Section 2(d) shall be true and correct other than in any de minimis respect,
and Holdco shall have duly performed, complied with and satisfied in all
material respects all covenants, agreements and conditions required by this

respects all covenants, agreements and conditions required by this Agreement

this Agreement.

               (iv) Since the date of this Agreement, Holdco and its
subsidiaries taken as a whole shall not have suffered a Holdco Material

               (v) All filings, registrations, authorizations, permits,

          (d) Frustration of Closing Conditions. Neither FCG nor the Investor
may rely on the failure of any condition set forth in Sections 6(a), (b), (c)
or (d), respectively, to be satisfied if such failure was caused by such
party's failure to perform its obligations hereunder or to use its
commercially reasonable efforts to cause the Closing to occur as required by
Section 6.

     7. Further Assurances. From time to time, as and when requested by
another party hereto, a party hereto shall execute and deliver, or cause to be

other than the parties hereto and such permitted successors and assigns, any
legal or equitable rights hereunder.

Agreement shall be effective unless it shall be in writing and signed by the

5(A)(b) of the Merger Agreement, for the period of any applicable statute of
limitations) following the Closing. Notwithstanding anything to the contrary
contained in the foregoing, nothing in this Section 11 is intended to indicate
that any representation or warranty will be true at any time other than at the
time of execution of this Agreement and at the Closing.

     12. Indemnification.

          (a) Indemnity by Holdco and FCG. Holdco and FCG shall, jointly and
severally, indemnify the Investor and its affiliates, controlling persons,
constituent partners and subsidiaries and their directors, officers, members,
employees against all expenses, costs, losses, claims, damages, liabilities
and judgments (including, without limitation, reasonable attorney's fees and
expenses) incurred or sustained by any such party resulting from (i) any
breach of the representations and warranties of Holdco set forth in Section 2
or FCG set forth in Section 3, (ii) FCG's, Holdco's or VANTAS' acts or failure
to act, (iii) any misstatements or omissions made in any disclosure or other
information or materials delivered or made available to the Investor in
connection with the investment contemplated under this Agreement, (iv) the
action or failure to act by an indemnified party with FCG's, Holdco's or
VANTAS' consent or in reliance on FCG's, Holdco's or VANTAS' action or failure
to act or (v) any and all environmental liabilities, costs and expenses
arising out of or incurred in connection with the consummation of the Merger,
the Second Step Merger or the investment contemplated in this Agreement;
provided, however, that such indemnity shall not extend to any expenses,
costs, losses, claims, damages, liabilities or judgments to the extent arising
out of (A) the gross negligence or willful misconduct of any person
indemnified under this Section 12(a) as determined by a court of competent
jurisdiction in a final, non-appealable judgment or (B) a breach by the
Investor of its representations and warranties contained herein.

     FCG agrees to indemnify the Investor against any Company Level Loss or
Direct Loss (each as defined below) directly or indirectly suffered or
incurred by it arising out of (i) Rule 10b-5 under the Exchange Act with
respect to VANTAS' failure to file reports with the Securities and Exchange
Commission as required under the Exchange Act prior to the date hereof or (ii)
the Shareholder Litigation (as defined in the Form of Indemnification and
Escrow Agreement attached as Exhibit E to the Merger Agreement (the
"Indemnification Agreement"). FCG shall pay the Investor, in full and complete
satisfaction of FCG's obligation under clause (ii) in this paragraph, an
amount (which, in the case of a Direct Loss, shall not exceed such Direct
Loss) equal to the product of (A) a fraction, the numerator of which equals
the sum of the number of shares of Preferred Stock (determined on an
As-Converted Basis) and the number of shares of Common Stock purchasable upon
exercise of the Initial Warrants, in each case owned by the Investor at the
Closing, and the denominator of which equals the sum of the number of shares
of Preferred Stock (determined on an As-Converted Basis) and the number of
shares of Common Stock purchasable upon exercise of the Initial Warrants, in
each case owned by the Investor at the Closing, and the number of shares of
Common Stock owned by FCG at the Closing, multiplied by (B) the dollar value
of any recovery obtained by FCG from CarrAmerica under the Indemnification
Agreement. A "Company Level Loss" shall mean any loss, liability, claim,
damage or expense (including, without limitation, reasonable attorney's fees
and expenses) incurred by Holdco or Old HQ or its successor; it being
understood that a Company Level Loss shall not include (i) any consequential,
incidental or punitive damages or (ii) any Direct Loss; it being understood
that a Company Level Loss shall include any loss or damage suffered by the
Investor as a result of a diminution in value (either directly or indirectly)
of the interest held by the Investor in Holdco. A "Direct Loss" shall mean any
loss, liability, claim, damage or expense (including reasonable attorney's
fees and expenses) incurred by the Investor; it being understood that a Direct
Loss shall not include (i) any consequential, incidental or punitive damages,
(ii) any Company Level Loss or (iii) any loss or damage suffered by the
Investor as a result of a diminution in value (either directly or indirectly)
of the interest held by the Investor in Holdco.

          (b) Indemnity by the Investor. The Investor shall indemnify FCG,
Holdco and their respective directors, officers and employees against all
expenses, costs, losses, claims, damages, liabilities and judgments
(including, without limitation, reasonable attorney's fees and expenses)
incurred or sustained by any such party resulting from any breach of the
representations and warranties of the Investor set forth in Section 4;
provided, however, that such indemnity shall not extend to any expenses,
costs, losses, claims, damages, liabilities and judgments to the extent
arising out of (A) the gross negligence or willful misconduct of any person
indemnified under this Section 12(b) as determined by a court of competent
jurisdiction in a final, non-appealable judgment or (B) a breach by Holdco or
FCG, as the case may be, of the representations and warranties set forth in
Section 2 or Section 3, respectively. Under no circumstances shall the
Investor be liable to FCG, Holdco or any other indemnified party under this
Section 12(b) for any punitive, exemplary, consequential or indirect damages
arising therefrom.

          (c) Notice of Actions or Proceedings. In case any action or
proceeding shall be commenced involving any party in respect of which
indemnity may be sought pursuant to Sections 12(a) or 12(b) (the "indemnified
party"), the indemnified party shall promptly notify the party against whom
such indemnity may be sought (the "indemnifying party") in writing of such
action or proceeding; provided, however, that failure of an indemnified party
to provide such notice shall not relieve the indemnifying party of its
obligations under this Section 12 if such failure does not materially and
adversely affect the rights of the indemnifying party.

          (d) Defense of Actions and Proceedings. The indemnifying party may
assume the defense of such action or proceeding provided that the expenses of
the indemnified party are reimbursed as they are incurred (including, without
limitation, the payment of all reasonable and documented fees and expenses of
counsel to the indemnified party) and the indemnifying party has not failed to
comply with any such reimbursement request. Any indemnified party shall have
the right to employ separate counsel in any such action or proceeding and
participate in the defense thereof, but the reasonable fees and expenses of
such counsel shall be at the expense of the indemnified party, unless (i) the
employment of such counsel shall have been specifically authorized in writing
by the indemnifying party, (ii) the indemnifying party shall have failed to
assume the defense of such action or proceeding or (iii) the named parties to
any such action (including any impleaded parties) include both the indemnified
party and the indemnifying party, and the indemnified party shall have been
reasonably advised by such counsel that the representation of the indemnifying
party and the indemnified party by the same counsel would be inappropriate due
to actual or potential differing interests between the indemnifying party and
the indemnified party or there are defenses that are available to the
indemnified party that may be in conflict with or contradict those available
to the indemnifying party (in which case the indemnifying party shall not have
the right to assume the defense of such action on behalf of the indemnified
party). In any such case, the indemnifying party shall not, in connection with
any one action or separate but substantially similar or related actions or
proceedings in the same jurisdiction arising out of the same general
allegations or circumstances, be liable for the reasonable fees and expenses
of more than one separate firm of attorneys for all indemnified parties and
all such reasonable fees and expenses shall be reimbursed as they are
incurred. The indemnifying party shall indemnify and hold harmless the
indemnified party from and against any and all expenses, costs, losses,
claims, damages, liabilities and judgments by reason of any settlement made by
the indemnified party of any action effected with the indemnifying party's
written consent. The indemnifying party shall not, without the prior written
consent of the indemnified party, effect any settlement or compromise of, or
consent to the entry of judgment with respect to, any pending or threatened
action or proceeding in respect of which the indemnified party is or could
have been a party and indemnity may be or could have been sought hereunder by
the indemnified party, unless (i) such settlement, compromise or judgment
includes an unconditional release of the indemnified party from all liability
on claims that are the subject matter of such action or proceeding and does
not include a statement as to or an admission of fault or culpability by or on
behalf of the indemnified party and (ii) reasonable prior written notice of
settlement, compromise or judgment is given to the indemnified party.

     13. Notices. All notices or other communications required or permitted to
be given hereunder shall be in writing and shall be delivered by hand or sent
by prepaid telex, cable or telecopy or sent, postage prepaid, by registered,

          Merger, each outstanding option to purchase shares of VANTAS Common
          Stock granted under the VANTAS 1996 Stock Option Plan (the "VANTAS
          1996 Stock Options"), is automatically amended to constitute an
          option to acquire the number of shares of Voting Common Stock of the
          Company as the holder of such VANTAS 1996 Stock Option would have
          been entitled to receive as Merger Consideration in the Merger had
          such holder exercised such VANTAS 1996 Stock Option (free of and
          without regard to any limitation on the vesting of the right to
          exercise such VANTAS 1996 Stock Option) immediately prior to the
          effective time of the Merger at an exercise price equal to the
          quotient of (a) the applicable exercise price for each such VANTAS
          1996 Stock Option immediately prior to the effective time of the
          Merger divided by (b) the Conversion Ratio.

          The following is a list of options granted under the VANTAS 1996
          Stock Option Plan that are subject to the foregoing:

          o   36,750 Options at an exercise price of $2.00

          o   40,458 Options at an exercise price of $4.00

     12.  As soon as practicable following the effective time of the Merger,
          Mr. Gary Kusin and Mr. David Rupert will receive options to purchase
          common stock of the Company with a value equal to 6X and 4X,
          respectively, of their respective Base Compensation, or $3,600,000
          or $1,600,000, respectively, which will become exercisable over a
          four-year period (37.5% after 18 months, then 12.5% every 6 months
          up to 100% in total, provided in each case that the executive is
          still employed by the Company on the applicable vesting date). The
          exercise price per share will equal the per share valuation used for
          purposes of the Merger.

     13.  As soon as practicable following the effective time of the Merger,
          Mr. Kusin and Mr. Rupert will receive a grant of restricted common
          stock in the Company with a value equal to 2.5X and 1.5X,
          respectively, of their respective Base Compensation, or $1,500,000
          or $600,000, respectively, which will become vested over a four-year
          period (37.5% after 18 months, then 12.5% every 6 months up to 100%
          in total, provided in each case that the executive is still employed
          by the Company on the applicable vesting date).

     14.  It is anticipated that options and restricted stock with respect to
          3% and 1%, respectively, of the outstanding common and preferred
          stock of the Company will be issued in connection with employee
          incentive compensation.
