On what's involved in carrying out today's agreement:

1) "Within 48 hours of the signing of this agreement, a special law will be adopted, signed and promulgated, which will restore the Constitution of 2004 including amendments passed until now."
That's up to the parliament - but the Prez's party is the biggest, & most of the oppo is in on this, so probably np there.
2) That's the intention, & the Constit'n (see Chapter XIII, i.e. articles 154-9) describes how it can be changed. In the single parliamentary chamber a motion needs the support of 300 or more People's Deputies (2/3rds of MPs). A referendum is needed for 3 particular chapters but these are extraneous to the agreement: General Principles; Elections & Referendum; & Introducing Amendments to the Constitution of Ukraine.

3) "Signatories declare their intention to create a coalition and form a national unity government within 10 days thereafter [after the new law]"
So a GNU by Wed. morn, 5 March.
4) It means, doesn't it, that Svoboda will have a ministry, if not two? Maybe guardian of the nation's culture? After all, Fini ran the Italian Culture Ministry. Or maybe a xenophobic nationalist imposing policy at the Ministry of Youth & Sport, or of Education & Science? Unlikely is Defence, Internal Affairs, or Justice - but you never know.
At the moment, besides the PM, there are 22 jobs: 4 Deputy PMs (!), & 18 Ministers. Expect that no. to increase, even though 10 of the incumbents are in no party.

5) It's unclear what #2 of the statement means, "Constitutional reform, balancing the powers of the President, the government and parliament, will start immediately and be completed in September 2014", as #1 describes the Constit'n changing within 48hrs.
6) The Communist Party seems to have been written out of the opposition, even though it is the 4th largest party, almost as many votes in 2012 as the boxer's party (#4).
7) Blonde-babe-in-jail party, boxer party, & Svoboda have agreed to "undertake serious efforts for the normalisation of life in the cities and villages by withdrawing from administrative and public buildings and unblocking streets, city parks and squares. Illegal weapons should be handed over to the Ministry of Interior bodies within 24 hours of the special law" (#5). We'll see how all that goes.
8) Please note, nothing in the agreement on blonde-babe-in-jail, Yulia.
ADDED: #3 of the statement says, "Presidential elections will be held as soon as the new Constitution is adopted but no later than December 2014". The phrase "as soon as" is surprising in that #1 speaks of instituting by Sunday morning the 2004 Constitution (i.e. as amended by the 8 Dec 2004 law).
